Dr. Neeraj Agarwal and Dr. Peter Hoskin discuss key abstracts in GU cancers from the 2025 ASCO Genitourinary Cancers Symposium, including novel therapies in prostate, bladder, and kidney cancer and the impact of combination therapies on patient outcomes. TRANSCSRIPT Dr. Neeraj Agarwal: Hello, and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, the director of the Genitourinary Oncology Program and professor of medicine at the Huntsman Cancer Institute at the University of Utah, and editor-in-chief of ASCO Daily News. Today, we'll be discussing practice-informing abstracts and other key advances in GU oncology featured at the 2025 ASCO Genitourinary Cancers Symposium. Joining me for this discussion is Dr. Peter Hoskin, the chair of this year's ASCO GU Symposium. Dr. Hoskin is a professor in clinical oncology in the University of Manchester and honorary consultant in clinical oncology at the Christie Hospital, Manchester, and University College Hospital London, in the United Kingdom. Our full disclosures are available in the transcript of this episode. Peter, thank you for joining us today. Dr. Peter Hoskin: Thank you so much, Neeraj. I am very pleased to be here. Dr. Neeraj Agarwal: The GU meeting highlighted remarkable advancements across the spectrum of GU malignancies. What stood out to you as the most exciting developments at the ASCO GU Symposium?  Dr. Peter Hoskin: The theme of this year's meeting was "Driving Innovation, Improving Patient Care," and this reflected ASCO GU's incredible milestone in GU cancer research over the years. We were thrilled to welcome almost 6,000 attendees on this occasion from over 70 countries, and most of them were attending in person and not online, although this was a hybrid meeting. Furthermore, we had more than 1,000 abstract submissions. You can imagine then that it fostered fantastic networking opportunities and facilitated valuable knowledge and idea exchanges among experts, trainees, and mentees. So, to start I'd like to come back to you for a second because the first day started with a focus on prostate cancer and some of the key clinical trials. And congratulations to you, Neeraj, on sharing the data from the TALAPRO-2 trial, which we were eagerly awaiting. I'd love to get your thoughts on the data that you presented. Could you tell us more about that trial, Abstract LBA18?  Dr. Neeraj Agarwal: Yes, Peter, I agree with you. It was such an exciting conference overall and thank you for your leadership of this conference. So, let's talk about the TALAPRO-2 trial. First of all, I would like to remind our audience that the combination of talazoparib plus enzalutamide was approved by the U.S. FDA in June 2023 in patients with metastatic castration-resistant prostate cancer harboring HRR gene alterations, after this combination improved the primary endpoint of radiographic progression-free survival compared to enzalutamide alone in the randomized, double-blind, placebo-controlled, multi-cohort phase 3 TALAPRO-2 trial. In the abstract I presented at ASCO GU 2025, we reported the final overall survival data, which was a key alpha-protected secondary endpoint in cohort 1, which enrolled an all-comer population of patients with mCRPC. So, at a median follow-up of around 53 months, in the intention-to-treat population, the combination of talazoparib plus enzalutamide significantly reduced the risk of death by 20% compared to enzalutamide alone, with a median OS of 45.8 months in the experimental arm versus 37 months in the control arm, which was an active control arm of enzalutamide. This improvement was consistent in patients with HRR alterations with a hazard ratio of 0.54 and in those with non-deficient or unknown HRR status, with a hazard ratio of 0.87. In a post hoc analysis, the hazard ratio for OS was 0.78 favoring the combination in those patients who did not have any HRR gene alteration in their tumors by both tissue and ctDNA testing. Consistent with the primary analysis, the updated rPFS data also favored the experimental arm with a median rPFS of 33.1 compared to 19.5 months in the control arm, and a hazard ratio of 0.667. No new safety signals were identified with extended follow-up. Thus, TALAPRO-2 is the first PARP inhibitor plus ARPI study to show a statistically significant and a clinically meaningful improvement in OS compared to standard-of-care enzalutamide as first-line treatment in patients with mCRPC unselected for HRR gene alterations. Dr. Peter Hoskin: Thank you, Neeraj. That's a great summary of the data presented and very important data indeed. There was another abstract also featured in the same session, Abstract 20, titled “Which patients with metastatic hormone-sensitive prostate cancer benefit more from androgen receptor pathway inhibitors? STOPCAP meta-analyses of individual participant data.” Neeraj, could you tell us more about this abstract? Dr. Neeraj Agarwal: Absolutely, I would be delighted to. So, in this meta-analysis, Dr. David Fischer and colleagues pooled individual participant data from different randomized phase 3 trials in the mHSPC setting to assess the potential ARPI effect modifiers and determine who benefits more from an ARPI plus ADT doublet. The primary outcome was OS for main effects and PFS for subgroup analyses. Prostate cancer specific survival was a sensitivity outcome. The investigators pooled data from 11 ARPI trials and more than 11,000 patients. Overall, there was a clear benefit of adding an ARPI on both OS and PFS, with hazard ratios of 0.66 and 0.51, respectively, representing a 13% and 21% absolute improvement at 5 years, respectively, with no clear difference by the class of agent. When stratifying the patients by age group, the effects of adding an ARPI on OS and PFS were slightly smaller in patients older than 75, than in those younger than 65, or aged between 65 and 75 years. Notably, in the trials assessing the use of abiraterone, we saw very little OS effects in the group of patients older than 75, however there was some benefit maintained in prostate-cancer specific survival, suggesting that other causes of death may be having an impact. The effects of the other ARPIs, or ‘lutamides' as I would call them, were similar across all three age subgroups on both OS and PFS. Therefore, the majority of patients with mHSPC benefit from the addition of ARPIs, and the benefits/risks of abiraterone and other ‘amides' must be considered in older patients.  Dr. Peter Hoskin: Thanks, Neeraj. Another great summary relevant to our day-to-day practice. Of course, there's ongoing collection of individual patient data from other key trials, which will allow robust comparison of ARPI doublet with triplet therapy (including docetaxel), guiding more personalized treatment.   Dr. Neeraj Agarwal: I agree with you, Peter, we need more data to help guide personalized treatment for patients with mHSPC and potentially guide de-escalation versus escalation strategies. Now, moving on to a different setting in prostate cancer, would you like to mention Abstract 17 titled, “Overall survival and quality of life with Lu-PSMA-617 plus enzalutamide versus enzalutamide alone in poor-risk, metastatic, castration-resistant prostate cancer in ENZA-p (ANZUP 1901),” presented by Dr. Louise Emmett? Dr. Peter Hoskin: Of course I will. So, ENZA-p was a multicenter, open-label, randomized, phase 2 trial conducted in Australia. It randomized 163 patients into adaptive doses (2 or 4 cycles) of Lu-PSMA-617 plus enzalutamide versus enzalutamide alone as first-line treatment in PSMA-PET-CT-positive, poor-risk, mCRPC. The interim analysis of ENZA-p with median follow-up 20 months showed improved PSA-progression-free survival with the addition of Lu-PSMA-617 to enzalutamide. Here, the investigators reported the secondary outcomes, overall survival, and health-related quality of life (HRQOL). After a median follow up of 34 months, overall survival was longer in the combination arm compared to the enzalutamide arm, with a median OS of 34 months compared to 26 months; with an HR of 0.55. Moreover, the combination improved both deterioration-free survival and health-related quality of life indicators for pain, fatigue, physical function, and overall health and quality of life compared to the control arm. Consistent with the primary analysis, the rPFS also favored the experimental arm with a median rPFS of 17 months compared to 14 months with a HR of 0.61. So, the addition of LuPSMA improved overall survival, and HRQOL in patients with high-risk mCRPC. Dr. Neeraj Agarwal: Thank you, Peter. Great summary, and promising results with Lu-177 and ARPI combination in first line treatment for mCRPC among patients who had two or more high risk features associated with early enzalutamide failure. Before we move on to bladder cancer, would you like to tell us about Abstract 15 titled, “World-wide oligometastatic prostate cancer (omPC) meta-analysis leveraging individual patient data (IPD) from randomized trials (WOLVERINE): An analysis from the X-MET collaboration,” presented by Dr. Chad Tang?  Dr. Peter Hoskin: Sure. So, with metastatic-directed therapy (MDT), we have a number of phase 2 studies making up the database, and the X-MET collaboration aimed to consolidate all randomized data on oligometastatic solid tumors. This abstract presented pooled individual patient data from all the published trials involving patients with oligometastatic prostate cancer who received MDT alongside standard of care (SOC) against SOC alone. The analysis included data from five trials, encompassing 472 patients with oligometastatic prostate cancer, and followed for a median of 41 months. Patients were randomly assigned in a 1:1 ratio to receive either MDT plus SOC or SOC alone. The addition of MDT significantly improved PFS. The median PFS was 32 months with MDT compared to 14.9 months with SOC alone, with an HR of 0.45. Subgroup analyses further confirmed the consistent benefits of MDT across different patient groups. Regardless of factors like castration status, receipt of prior primary treatment, stage, or number of metastases, MDT consistently improved PFS. In patients with mHSPC, MDT significantly delayed the time to castration resistance by nine months, extending it to a median of 72 months compared to 63 months in the SOC group with an HR of 0.58. In terms of OS, the addition of MDT improved the 48-month survival rate by 12%, with OS rates of 87% in the MDT+SOC group compared to 75% in the SOC alone group. Dr. Neeraj Agarwal: Thank you, Peter. These data demonstrate that adding MDT to systemic therapy significantly improves PFS, rPFS, and castration resistance-free survival, reinforcing its potential role in the treatment of oligometastatic prostate cancer. So, let's switch gears to bladder cancer and start with Abstract 658 reporting the OS analysis of the CheckMate-274 trial. Would you like to tell us about this abstract?  Dr. Peter Hoskin: Yes, sure, Neeraj. This was presented by Dr. Matt Milowsky, and it was additional efficacy outcomes, including overall survival, from the CheckMate-274 trial which evaluated adjuvant nivolumab versus placebo in patients with high-risk muscle-invasive bladder cancer after radical surgery. The phase 3 trial previously demonstrated a significant improvement in disease-free survival with nivolumab. With a median follow-up of 36.1 months, disease-free survival was longer with nivolumab compared to placebo across all patients with muscle-invasive bladder cancer, reducing the risk of disease recurrence or death by 37%. Among patients who had received prior neoadjuvant cisplatin-based chemotherapy, nivolumab reduced this risk by 42%, whilst in those who had not received chemotherapy, the risk was reduced by 31%. Overall survival also favored nivolumab over placebo, reducing the risk of death by 30% in all patients with muscle-invasive bladder cancer and by 52% in those with tumors expressing PD-L1 at 1% or higher. Among patients who had received prior neoadjuvant chemotherapy, nivolumab reduced the risk of death by 26%, whilst in those who had not received chemotherapy, the risk was reduced by 33%. Alongside this, the safety profile remained consistent with previous findings. Dr. Neeraj Agarwal: Thank you, Peter, for such a nice overview of this abstract. These results reinforce adjuvant nivolumab as a standard of care for high-risk muscle-invasive bladder cancer, offering the potential for a curative outcome for our patients. Dr. Peter Hoskin: I agree with you Neeraj. Perhaps you would like to mention Abstract 659 titled, “Additional efficacy and safety outcomes and an exploratory analysis of the impact of pathological complete response (pCR) on long-term outcomes from NIAGARA.” Dr. Neeraj Agarwal: Of course. Dr. Galsky presented additional outcomes from the phase 3 NIAGARA study, which evaluated perioperative durvalumab combined with neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer. The study previously demonstrated a significant improvement in event-free survival and overall survival with durvalumab compared to chemotherapy alone, with a manageable safety profile and no negative impact on the ability to undergo radical cystectomy. Among the 1,063 randomized patients, those who received durvalumab had a 33% reduction in the risk of developing distant metastases or death and a 31% reduction in the risk of dying from bladder cancer compared to those who received chemotherapy alone. More patients who received durvalumab achieved a pathological complete response at the time of surgery with 37% compared to 28% in the chemotherapy-alone group. Patients who achieved a pathological complete response had better event-free survival and overall survival compared to those who did not. In both groups, durvalumab provided additional survival benefits, reducing the risk of disease progression or death by 42% and the risk of death by 28% in patients with a pathological complete response, while in those patients without a pathological complete response, the risk of disease progression or death was reduced by 23% and the risk of death by 16% when durvalumab was added to the chemotherapy. Immune-mediated adverse events occurred in 21% of patients in the durvalumab group compared to 3% in the chemotherapy-alone group, with grade 3 or higher events occurring in 3% compared to 0.2%. The most common immune-related adverse events included hypothyroidism in 10% of patients treated with durvalumab compared to 1% in the chemotherapy-alone group, and hyperthyroidism in 3% versus 0.8%. At the time of the data cutoff, these adverse events had resolved in 41% of affected patients in the durvalumab group and 44% in the chemotherapy-alone group. Dr. Peter Hoskin: Thank you, Neeraj, for the great summary. These findings further support the role of perioperative durvalumab as a potential standard of care for patients with muscle-invasive bladder cancer. Dr. Neeraj Agarwal: I concur with your thoughts, Peter. Before wrapping up the bladder cancer section, would you like to mention Abstract 664 reporting updated results from the EV-302 trial, which evaluated enfortumab vedotin in combination with pembrolizumab compared to chemotherapy as first-line treatment for patients with previously untreated locally advanced or metastatic urothelial carcinoma? Dr. Peter Hoskin: Yes, of course. Dr. Tom Powles presented updated findings from the EV-302 study, and in this abstract presented 12 months of additional follow-up for EV-302 (>2 y of median follow-up) and an exploratory analysis of patients with confirmed complete response (cCR). The study had a median follow-up of 29.1 months and previously demonstrated significant improvements in progression-free survival and overall survival with enfortumab vedotin and pembrolizumab. This is now the standard of care in global treatment guidelines. Among the 886 randomized patients, enfortumab vedotin and pembrolizumab reduced the risk of disease progression or death by 52% and the risk of death by 49% compared to chemotherapy. The survival benefit was consistent regardless of cisplatin eligibility or the presence of liver metastases. The confirmed objective response rate was higher with enfortumab vedotin and pembrolizumab at 67.5% compared to 44.2% with chemotherapy. The median duration of response was 23.3 months with enfortumab vedotin and pembrolizumab compared to 7.0 months with chemotherapy. A complete response was achieved in 30.4% of patients in the enfortumab vedotin and pembrolizumab group compared to 14.5% in the chemotherapy group, with the median duration of complete response not yet reached in the enfortumab vedotin and pembrolizumab group compared to 15.2 months in the chemotherapy group. Severe treatment-related adverse events occurred in 57.3% of patients treated with enfortumab vedotin and pembrolizumab compared to 69.5% in the chemotherapy group, while in patients who achieved a complete response, severe adverse events occurred in 61.7% of those treated with enfortumab vedotin and pembrolizumab compared to 71.9% with chemotherapy. Treatment-related deaths were reported in 1.1% of patients treated with enfortumab vedotin and pembrolizumab compared to 0.9% with chemotherapy, with no treatment-related deaths occurring in those who achieved a complete response. These findings clearly confirm the durable efficacy of enfortumab vedotin and pembrolizumab, reinforcing its role as the standard of care for the first-line treatment of patients with locally advanced or metastatic urothelial carcinoma, and no new safety concerns have been identified. Dr. Neeraj Agarwal: Thank you for this great summary. Moving on to kidney cancer, let's talk about Abstract 439 titled, “Nivolumab plus cabozantinib (N+C) vs sunitinib (S) for previously untreated advanced renal cell carcinoma (aRCC): Final follow-up results from the CheckMate-9ER trial.” Dr. Peter Hoskin: Sure. Dr. Motzer presented the final results from the phase 3 CheckMate-9ER trial, which compared the combination of cabozantinib and nivolumab against sunitinib in previously untreated advanced renal cell carcinoma. The data after more than five years follow-up show that the combination therapy provided sustained superior efficacy compared to sunitinib. In terms of overall survival, we see an 11-month improvement in median OS, 46.5 months for the cabo-nivo versus 35.5 months for sunitinib and a 42% reduction in the risk of disease progression or death, with median progression-free survival nearly doubling – that's 16.4 months in the combination group and 8.3 months with sunitinib. Importantly, the safety profile was consistent with the known safety profiles of the individual medicines, with no new safety concerns identified. Dr. Neeraj Agarwal: Great summary, Peter. These data further support the efficacy of cabo-nivo combination therapy in advanced renal cell carcinoma, which is showing a 11-month difference in overall survival. Dr. Peter Hoskin: Neeraj, before wrapping up this podcast, would you like to tell us about Abstract 618? This is titled “Prospective COTRIMS (Cologne trial of retroperitoneal lymphadenectomy in metastatic seminoma) trial: Final results.” Dr. Neeraj Agarwal: Sure, Peter. I would be delighted to. Dr Heidenrich from the University of Cologne in Germany presented the COTRIMS data evaluating retroperitoneal LN dissection in patients with clinical stage 2A/B seminomas. Seminomas are classified as 2A or B when the disease spreads to the retroperitoneal lymph nodes of up to 2 cm (CS IIA) or of more than 2 cm to up to 5 cm (CS 2B) in maximum diameter, respectively. They account for 10-15% of seminomas and they are usually treated with radiation and chemotherapy. However, radiation and chemo can be associated with long-term toxicities such as cardiovascular toxicities, diabetes, solid cancers, leukemia, particularly for younger patients. From this standpoint, Dr Heidenrich and colleagues evaluated unilateral, modified template, nerve-sparing retroperitoneal lymph node dissection as a less toxic alternative compared to chemo and radiation. They included 34 patients with negative AFP, beta-HCG, and clinical stage 2A/B seminomas. At a median follow-up of 43.2 months, the trial demonstrated great outcomes: a 99.3% treatment-free survival rate and 100% overall survival, with only four relapses. Antegrade ejaculation was preserved in 88% of patients, and severe complications such as grade 3 and 4 were observed in 12% of patients. Pathological analysis revealed metastatic seminoma in 85% of cases, with miR371 being true positive in 23 out of 24 cases and true negative in 100% of cases. It appears to be a valid biomarker for predicting the presence of lymph node metastases. These findings highlight retroperitoneal lymph node dissection is feasible; it has low morbidity, and excellent oncologic outcomes, avoiding overtreatment in 80% of patients and sparing unnecessary chemotherapy or radiotherapy in 10-15% of cases. Dr. Peter Hoskin: Great summary and important data on retroperitoneal lymphadenectomy in metastatic seminoma. These findings will help shape clinical practice. Any final remarks before we conclude today's podcast? Dr. Neeraj Agarwal: Before wrapping up this podcast, I would like to say that we have reviewed several abstracts addressing prostate, bladder, kidney cancers, and seminoma, which are impacting our medical practices now and in the near future.

We love to hear from our listeners. Send us a message. For all the drug commercialization successes he's played a leading hand in during his tenures at GSK, Genentech, and ImClone—Androderm, Augmentin, necitumumab, and Erbitux among them—Michael Bailey concedes that he's likely better known for his failures. After hearing his stories on this episode of the Business of Biotech, I tend to disagree. While he offers a transparent and instructive look at the failures themselves, I'd contend it's what he's done with those setbacks that defines his biopharma and biotech leadership legacy. Today, Bailey is CEO at Aveo Oncology, a company that saw its own set of challenges during the clinical development of now-commercial FOTIVDA (tivozanib) and ficlatuzumab.

Dr. Pedro Barata and Dr. Lillian Siu discuss recent advances in cancer vaccines and biomarkers, including the potential of the neoantigen and immune modulatory vaccines and the challenges surrounding cancer vaccine development. TRANSCRIPT Dr. Pedro Barata: Hello, I'm Dr. Pedro Barata, your guest host for the ASCO Daily News Podcast today. I'm a GU medical oncologist at the University Hospitals Seidman Cancer Center in Cleveland, Ohio, and an associate professor of medicine at Case Western Reserve University School of Medicine. I'm also an associate editor of the ASCO Educational Book. And today we'll be discussing a timely article that was recently published in the Educational Book titled, “State-Of-The-Art Advancements on Cancer Vaccines and Biomarkers.”   I'm delighted to welcome one of the article's co-authors and a world-renowned oncologist, Dr. Lillian Siu. She is a senior medical oncologist and director of the Phase 1 Program at the Princess Margaret Cancer Center and a professor of medicine at the University of Toronto.  Welcome, Dr. Siu. Dr. Lillian Siu: Thank you, Dr. Barata; it's great to be here. Dr. Pedro Barata: Wonderful. Dr. Siu will discuss new tools for cancer vaccine development, strategies for combating the immunosuppressive and tumor microenvironment. She will also address cancer vaccine guidelines and patient recruitment strategies to optimize patient selection and access to cancer vaccine trials. I should say that Dr. Siu and her co-authors also addressed this topic during an Education Session at the ASCO 2024 Annual Meeting.  Finally, our full disclosures are available in the transcript of this episode.  So again, Dr. Siu, great to be speaking with you today. I'm looking forward to our discussion.  Dr. Lillian Siu: Thank you, Dr. Barata. And before I begin, I want to acknowledge Dr. Jeffrey Weber and Dr. Inge Marie Svane, who both presented during the ASCO session you mentioned. They gave excellent presentations related to the topic of neoantigen vaccines and immune-modulatory vaccines, which we will talk about later. Dr. Pedro Barata: Wonderful. So let's get started. Cancer vaccines are among the most promising frontiers for breakthrough innovations and new strategies in the fight against cancer. The successes in vaccine development during the COVID-19 pandemic, I think, inspired further research in this area. Why do you think it's important that we harness these recent successes and technological advances to really accelerate progress in vaccine development? Dr. Lillian Siu: Absolutely. I think all of us who have lived through COVID really appreciated how important the COVID vaccine development was to all of us. It saved millions of lives. And I think we witnessed a paradigm change in drug development that none of us thought was possible, that we're able to actually bring a concept to a drug from bench to bedside within an extremely short time. That timeline is not something we would ever imagine to have happened, and it did. And I think it gives us hope that perhaps this is not just limited to the COVID vaccine; it's also extrapolatable to other therapeutics – that we can bring promising medicines to our patients in a really expedited timeline, obviously without compromising their safety.  We now know that cancer vaccines have entered a new, or maybe I should say, renewed era of promise. And it's holding promise on many fronts, Pedro, if I may. It's very exciting in the area of molecular residual disease. In other words, a setting where the cancer is treated definitively by surgery or radiation, plus adjuvant treatment. And we know some patients will relapse because we know they're at high risk. And now we also have different ways to detect these microscopic risks, such as by ctDNA, circulating tumor DNA, or biomarkers. And we know that having some therapeutic that can eradicate these cancers at such microscopic levels would be very attractive, especially with low toxicity, and I think cancer vaccine is such a candidate. And of course, we can even look further into the future of using such treatment in cancer prevention, especially in those with high risk of developing cancer, for example, those with hereditary syndromes like lynch syndrome. We're not there yet, but I think it holds that promise.   So I think, going back to your original question, if we can develop such a therapeutic that is showing promise in a very short period of time, it brings the timeline and the hope to a much shorter timeframe to really deliver to our patients in a very timely manner while safeguarding all the important parts, such as safety and tolerability. Dr. Pedro Barata: Wow, those are such important points. I couldn't agree with you, more. It's really exciting. As I think through this, and as I was reading through your piece, I was thinking it would be great if you could highlight some of the novel approaches to personalized neoantigen vaccine development that are driving progress in this space. Dr. Lillian Siu: Absolutely. And during the session, Dr. Weber spoke about the neoantigen vaccine, and he's a pioneer in this space. So I can only try to iterate some of the points he had delivered during his talk. Neoantigen is a very exciting space for immunologists because we know that tumors express these neoantigens. Many of these are unique antigens that are only expressed in tumors, so-called tumor specific antigens, that we can use as our targets, including vaccines, but not limited to vaccines. And with these altered sequences in DNA in different forms, they could be mutations and splice alterations, etc. We expect that we have modified proteins that are expressed by tumor cells, and these become targets for our drug development of vaccines. And now we can have very specific strategies, very sophisticated algorithms to figure out which neoantigens are more so called immunogenic, more likely to stimulate or activate the immune system, and they can be recognized by T cells. So leveraging this knowledge and technology, we have been able to develop especially mRNA vaccines that are deliverable to our patients through different mechanisms, for example, in lipopeptides, etc., so that we can deliver to the patients in a safe way, such that we can use it to deliver vaccines, such as in the MRD setting that I mentioned earlier, as well as in the advanced disease setting. So Dr. Weber, in his presentation, highlighted one of such vaccines that have been tested in a randomized controlled trial that is KEYNOTE-942, which randomized 157 patients to the mRNA vaccine plus pembrolizumab versus pembrolizumab alone in patients with advanced melanoma. This is a vaccine against 34 mutated neoantigens, and it showed a significant difference in the recurrence free survival with a hazard ratio of 0.56. And if you look at the 18-month relapse free survival rate, it was 78.6% versus 62.2%. Obviously, these are still fairly early data and numbers are still small. I think we would definitely look forward to the randomized phase 3 study of neoantigen vaccine in melanoma and other cancers. Dr. Pedro Barata: No, absolutely. And I agree, it's really exciting. Dr. Weber did a fantastic job going through some of that data. So let me ask you Dr. Siu, as you think about this cancer vaccine field, what are the limitations that you'd highlight when you think about cancer vaccine development? What challenges do you encounter, obstacles do you encounter?  Dr. Lillian Siu: There are many, many potential challenges. And to some extent, that's probably why cancer vaccine development has been somewhat slow for the many decades until more recently. We know first of all; the target has to be recognized. So we need immunogenic targets. So I think a lot of the effort has been put into trying to understand which antigens expressed by cancer cells are immunogenic, able to activate the immune system. They're obviously assay based methods. You're going to try and see if you can ex vivo stimulate immune cells on dishes and models, etc. But we need to also develop in silico computerized algorithms, and now with AI, I think that makes it even more tangible and exciting that we can actually understand through a large number of neoantigens or other antigens, whether we can choose the ones that are most likely going to actually stimulate T cells to be activated. And I think that is one area that there is a lot of interest in development, how to really develop ways to select out the most attractive antigens.   I would also want to highlight that the platforms, which is how we deliver the vaccine, can also pose significant challenges. For example, vaccines can be delivered using peptide-based formulation, cell-based formulation, nucleic acids and viral vectors. For some of these formulations, for example, the peptides very often are restricted to HLA. They can be rapidly degraded in the body, such that they become not really visible to the T cells anymore. Some of the formulations can be very complex. For example, the cell-base; it may need to have cells isolated from patients, cultured, stored and transported to the site of delivery, which can be very complex. For some of the nucleic acid vaccines, they can have very low transfection efficiency. It could be at risk for also having, for example, DNA vaccines integrated into the host genome. And then lastly, there's also the immune suppressive environment in the TME, such that it does not really have the effect when you give it repeatedly. It becomes attenuated and no longer effective. So these are some of the challenges associated with cancer vaccines.  Dr. Pedro Barata: Thank you for that summary. I think it's really important for folks out there, including researchers getting into this field, to be aware of potential obstacles they might encounter.  So let me ask you the opposite question as we see more compelling preclinical and clinical data emerging in this field of vaccine development, what is really exciting you the most about the newest technologies that are shaping the future of cancer vaccines, in your opinion?  Dr. Lillian Siu: I think one I want to highlight is the immune-modulatory vaccine that Dr. Svane, Dr. Inge Marie Svane had presented during the presentation at ASCO. This is a completely different strategy from the neoantigen vaccine. It targets antigens in the tumor microenvironment. And we know that in the tumor microenvironment, we have tumor cells, we have immune cells, and there are many types of cell types, including, for example, macrophages, cancer associated fibroblasts, regulatory T cells, etc. And using these particular cell types, we know that we can really develop vaccines that can stimulate the body's immune system to attenuate, to downgrade some of the negative factors in the tumor microenvironment. And this is what Dr. Svane and her group is trying to do. For example, they have an IDO vaccine that is able to actually target these antigens in the tumor microenvironment, and by that, not just suppressing the negative forces, so to speak, but also activate T cells to help attack cancer cells. I think that's a very interesting area. Very early promise has been seen already in non-small cell lung cancer in early phase trials using the immune-modulatory vaccine.  But going back to your question, what kind of advances; I mentioned earlier about having novel ways to select our antigens that are most immunogenic. There are many algorithms that are being developed, and I think we can try and leverage that kind of knowledge from artificial intelligence, machine learning. So I think that's definitely very exciting. There are also new vaccine platforms coming out. For example, there's recent data using modification of peptides, so called amphiphile vaccines, that already show very early promise in colorectal cancer, microsatellite status, colorectal cancer, as well as in pancreatic cancer in the molecular residual disease setting, where these long peptide vaccines targeting KRAS mutants together with adjuvant oligonucleotide DNA, combined together, can actually be given to patients and reduce the chance of cancer relapse in patients with resected colorectal cancer, as well as pancreatic cancer, with endpoints such as ctDNA or biomarker being downregulated. I think that's a very exciting example. Another very exciting example is cell-based vaccines that are being developed in Europe by the NKI Netherlands Cancer Institute Group, where they are looking at plasmacytoid dendritic cells that are loaded with peptides from different tumor associated antigens and then given to patients, which, again, in non-small cell lung cancer, together with pembrolizumab, has yielded very high response rate. And we will almost certainly see more trials coming out using that particular platform with the dendritic cells. So that's just some of the examples of exciting things that are happening in the vaccine field. Dr. Pedro Barata: Thank you. I'm wondering if you can share with our listeners about what really are the existing guidelines for using these new tools for discovery, methods of treatment, and perhaps optimizing patient selection to access trials.  Dr. Lillian Siu: To be honest, the latest guideline that was published from the FDA that I can find is almost 13 years ago in 2011. So I think it is time for a new guidance, or at least a draft guidance, to give some additional support and guidance in terms of what to do with these new treatments from the FDA and perhaps other regulatory agencies as well. I think we're now entering a very exciting time that cancer vaccines are no longer an ineffective therapeutic. It is now showing evidence of efficacy, not just in the advanced setting, but also in the molecular residual disease setting. There're so many questions to be answered, like how to develop these trials in early disease; what's the end point? Can we incorporate them into the neoadjuvant setting, and if so, how do we give these drugs before surgery, and do we give them maintenance after surgery? I think guidance from the regulatory authorities would be extremely helpful and informative to guide academic groups as well as the pharmaceutical sector to develop these agents in the right way. Dr. Pedro Barata: Dr. Siu, this is a fantastic summary, and we certainly are on the cusp of a new dawn of discovery and development in cancer vaccines, and super interesting to hear from you talking about it. Before letting you go, do you have any final thoughts that you'd like to share with the listeners, with all of us about this topic? Dr. Lillian Siu: I think as a drug developer like you are, I'm extremely excited because we now have yet another way to leverage the host immunity as a cancer therapeutic, and it is going to be opening a new door to combination therapy because we can imagine combining these treatments with other immunotherapeutics such as bispecific molecules such as CAR Ts and even vaccine plus vaccine combination is feasible. That came up actually during the session as a question from the audience. Can we combine neoantigen vaccines and immune-modulatory vaccines together? And both of our speakers who presented felt that it was possible. Obviously, we have to understand the sequence question and the endpoints question, but the fact that it opens a new door to combinatorial therapy, not just with immunotherapeutics, but perhaps with other therapeutics as well, antibody drug conjugates, etc., really, I think, is very exciting for this field to become further explored.  I mentioned earlier in the podcast that the whole area of cancer prevention is something that we have not been tapping into for the last decade with vaccines because it has not been very effective. Viral vaccines, of course, HPV and other vaccines targeting viruses, but targeting cancer cells is not something we have been successful using vaccines to prevent cancer from developing. I think we would be very interested to see if this will become a reality in the next decade. I think we would start off with patients with high risk of developing cancers such as, as I mentioned earlier, those with lynch syndrome, those harboring BRCA alterations, for example. Can we use these vaccines to actually prevent the cancers from developing in such high-risk individuals? I think the field is definitely open to that consideration.  Dr. Pedro Barata: Definitely. And I'd like to thank you, Dr. Siu, for sharing these great insights with us today on the ASCO Daily News Podcast.

Dr. Neeraj Agarwal and Dr. Rana McKay discuss promising studies in GU cancers featured at the 2024 ASCO Annual Meeting that highlighted improved outcomes in urothelial carcinoma, improved survival in renal cell carcinoma, and the role of ctDNA as a potential biomarker for predicting outcomes.   TRANSCRIPT Dr. Neeraj Agarwal: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, your guest host of the ASCO Daily News Podcast today. I am the director of the Genitourinary Oncology Program, a professor of medicine at the University of Utah's Huntsman Cancer Institute, and editor-in-chief of the ASCO Daily News.  I am delighted to welcome Dr. Rana McKay, a GU medical oncologist and associate professor at the University of California San Diego. Today, we'll be discussing some key GU abstracts featured at the 2024 ASCO Annual Meeting. Our full disclosures are available in the transcript of this episode. Rana, we're thrilled to have you on the podcast today to share your insights on key advances in GU oncology from ASCO24. Dr. Rana McKay: Thank you so much, Neeraj; it's a pleasure to be here. Dr. Neeraj Agarwal: So, Rana, let's start with some bladder cancer abstracts. Could you tell us about Abstract 4503, titled “Impact of exposure on outcomes with enfortumab vedotin in patients with locally advanced or metastatic urothelial cancer”? Dr. Rana McKay: Of course, I would be delighted to. First, I would like to remind our listeners that enfortumab vedotin (EV) was approved as a monotherapy for the treatment of locally advanced or metastatic urothelial cancer based on the results of EV-201 and EV-301 trials. In these pivotal studies, EV was initiated at a dose of 1.25 mg/kg, and dose modifications, such as reductions and interruptions, were used to manage adverse events. In the abstract presented at ASCO 2024, Dr. Daniel Petrylak and colleagues conducted a post-hoc exploratory analysis to evaluate the association between EV plasma exposure and outcomes. They used multiple pharmacokinetic samples collected during the first two cycles and pre-dose samples from 3 EV monotherapy studies, namely EV-101, EV-201, and EV-301, that were conducted in patients with previously treated locally advanced or metastatic urothelial carcinoma. Dose reductions to 1 mg/kg were required in 42.1% and 35.1% of patients in the EV-201 and EV-301 trials, respectively, and reductions to 0.75 mg/kg were required in 13.6% and 11.1% in the EV-201 and EV-301 trials, respectively. Higher EV exposure during the first two cycles was associated with a higher objective response rate. The ORR was 21.4% for the dose of 0.75 mg/kg, while it was 18.5% for the dose of 1.0 mg/kg. Interestingly, increasing the dosage to 1.25 mg/kg improved the ORR, which ranged from 40 to 51.1% across various studies. In the EV-301 trial, when comparing the efficacy of EV to chemotherapy, EV improved PFS and OS across all dose quartiles, and there was no evidence that recommended dose modifications impacted long-term efficacy outcomes. Dr. Neeraj Agarwal: Thank you, Rana, for this great summary. I would like to add that the meticulously conducted pharmacokinetic studies demonstrated that serum levels of EV correlated with responses. Importantly, patients who had to decrease the dose did not experience compromised outcomes as EV improved PFS and OS outcomes vs chemotherapy in across all exposure quartiles in the EV-301 trial where EV was compared with chemotherapy. These findings highlight the need to start at the recommended dose of 1.25 mg/kg and reduce it, if necessary, however, clinicians should not start at a lower dose.  Dr. Rana McKay: I totally agree with you, Neeraj. Now, moving on to a different setting in bladder cancer, what can you tell us about LBA4517, titled “Perioperative sacituzumab govitecan alone or in combination with pembrolizumab for patients with muscle-invasive urothelial bladder cancer: SURE-01/02 interim results”? Dr. Neeraj Agarwal: Of course! So, SURE was a multicohort, open-label, phase 2 study in patients with muscle-invasive bladder cancer assessing sacituzumab govitecan as a neoadjuvant therapy either alone in SURE-01 or as a combination with pembrolizumab followed by adjuvant pembro in SURE-02 in a flexible design allowing a bladder-sparing approach. In the abstract presented at ASCO 2024, Dr. Antonio Cigliola and colleagues report interim results of the SURE-01 study. Patients with cT2-4N0M0 urothelial carcinoma who were ineligible for or refused cisplatin-based neoadjuvant chemotherapy were planned to receive 4 cycles of neoadjuvant sacituzumab govitecan at a dose of 10 mg/kg followed by radical cystectomy.  An extensive assessment was performed at baseline and after the 4 cycles for response assessment. Patients with clinical complete response defined with negative MRI, cystoscopy and ctDNA assays refusing radical cystectomy were offered redo transurethral resection of the bladder tumor or repeat TURBT followed by observation in the absence of viable high-grade tumor in the bladder. The primary endpoint was pathological complete response rate, while secondary endpoints included pathological downstaging rate and safety. After the first 8 patients were enrolled, the protocol was amended due to the occurrence of grade 3 and 4 neutropenia and diarrhea in 75% and 50% of patients, respectively, and 2 deaths – one of which was deemed to be treatment-related due to sepsis. Key protocol changes included the reduction of the dose of sacituzumab govitecan to 7.5 mg/kg, the introduction of G-CSF as primary prophylaxis, and the exclusion of patients at high risk of febrile neutropenia per ASCO guidelines.  Among 21 patients who received at least one cycle of sacituzumab govitecan and included in the intention-to-treat population, 47.6% had a complete pathological response, and 52.4% had pathological downstaging. 11 patients underwent radical cystectomy, while 7 received repeat-TURBT due to complete clinical response or patient preference. Regarding the safety profile, grade 3 or more adverse events occurred in 42.5% of patients. Treatment-related adverse events leading to dose interruptions or discontinuations were more common before the protocol amendment. It is noteworthy that 3 patients died after treatment discontinuation, with one deemed treatment-related, as previously mentioned. Dr. Rana McKay: Thank you, Neeraj, for a great summary. The pathological complete responses observed show promising activity for sacituzumab govitecan as a neo-adjuvant therapy and a window for bladder-sparing approaches, which is definitely exciting news for our patients! However, although the 3 deaths encountered in a neo-adjuvant setting could be concerning, the improvement of the safety profile after protocol amendments is reassuring and supports the continuation of the study. Dr. Neeraj Agarwal: Before wrapping up the bladder cancer section, would you like to share your insights with our listeners on Abstract 4518, titled “Quantitative circulating tumor DNA (ctDNA) assessment in patients with advanced urothelial carcinoma treated with pembrolizumab or platinum-based chemotherapy from the phase 3 KEYNOTE-361 trial”?  Dr. Rana McKay: Sure. So, the KEYNOTE-361 trial was a randomized phase 3 study with 3 arms that included pembrolizumab plus chemotherapy, pembrolizumab monotherapy, or chemotherapy alone in patients with previously untreated advanced urothelial carcinoma. The results showed that neither the combination of pembrolizumab plus chemotherapy nor pembrolizumab monotherapy improved survival outcomes compared to the chemotherapy arm. So, in this exploratory analysis presented at ASCO24, Dr. Tom Powles and colleagues sought to assess the role of ctDNA as a potential biomarker between the pembrolizumab monotherapy arm and the chemotherapy arm. Tumor tissue mutations were evaluated using whole exome sequencing, and plasma ctDNA was assessed with the Guardant 360 assay. Changes in ctDNA from pre-treatment cycle 1 to on-treatment cycle 2, so 3 weeks post-baseline assessment, were quantified by the maximum variant allele frequency of tumor tissue-specific mutations.  Results showed that lower baseline ctDNA levels were associated with improved clinical outcomes of response in the pembrolizumab arm but not in the chemotherapy arm. This improvement in the pembrolizumab arm was also robust to adjustment for tumor mutational burden and PD-L1. Additionally, chemotherapy led to a ctDNA clearance rate of 41% compared to 11% in the pembrolizumab arm. Patients who had a large ctDNA reduction with pembrolizumab had significantly improved outcomes compared to those achieving a large reduction with chemotherapy with a hazard ratio of 0.25. However, this did not replicate in patients who did not achieve a large reduction, as these patients had similar outcomes across both arms. Let's switch gears to kidney cancer and start with Abstract 4508, reporting the final OS analysis from the JAVELIN Renal-101 trial. Neeraj, what would you like to tell us about this abstract? Dr. Neeraj Agarwal:  Well, as a quick reminder, the JAVELIN Renal-101 was a randomized phase 3 trial where patients with previously untreated advanced or metastatic clear cell renal cell carcinoma were randomized to receive either the combination of avelumab plus axitinib or sunitinib. In previous analyses, the combination of avelumab and axitinib significantly improved PFS compared to sunitinib and was subsequently approved by the FDA for the first-line treatment of patients with advanced RCC in 2019. This superiority in PFS was maintained across the different analyses; however, OS data remained immature. In the abstract presented at ASCO24 by Dr. Robert Motzer from Memorial Sloan Kettering Cancer Center and colleagues, the authors reported OS results at a median follow-up of around 73 months and a minimum of 68 months for all patients, which is the longest follow-up for any ICI-TKI combination in RCC. The final analysis in the overall population favored the combination of avelumab plus axitinib with a median OS of 44.8 months compared to 38.9 months with sunitinib, however, this did not reach statistical significance with a hazard ratio of 0.88. The PFS results and safety profile were consistent with previous analyses.  Dr. Rana McKay: Thank you, Neeraj, for such a nice overview of this abstract. These new data could make this regimen less optimal than other ICI-TKI combinations in the first-line mRCC setting.   Dr. Neeraj Agarwal: I concur, Rana. Moving on to perhaps one of the most exciting GU abstracts featured, Abstract 4506, titled “Circulating kidney injury molecule-1 biomarker analysis in IMmotion010: A randomized phase 3 study of adjuvant atezolizumab vs placebo in patients with renal cell carcinoma at increased risk of recurrence after resection.” Rana, what are your thoughts on this abstract? Dr. Rana McKay: Well, first, I would like to take a step back and remind our audience that in the IMmotion010 trial, patients with resected intermediate to high-risk RCC with clear cell and/or sarcomatoid component were randomized in a 1:1 ratio to receive either atezolizumab or placebo. Investigator-assessed disease-free survival, which was the primary endpoint, favored the atezolizumab arm but did not reach statistical significance. In the abstract featured at ASCO24, Dr. Laurence Albiges and colleagues build on data previously reported in the ASSURE and CheckMate 914 trials and report provocative findings regarding a molecule known as kidney injury molecule 1 or KIM-1, which is a type 1 membrane glycoprotein that has been identified as a minimally invasive potential peripheral blood circulating biomarker. The KIM-1 level of 86 pg/ml was identified as the optimized threshold for defining post-nephrectomy KIM-1 high vs KIM-1 low subgroups in the IMmotion010 trial. KIM-1 levels were measured at baseline or pre-treatment, at cycle 4 day 1, and at disease recurrence or discontinuation without disease recurrence. Baseline characteristics were balanced between the KIM-1 high and KIM-1 low groups, except perhaps for a slightly higher pathological stage in the KIM-1 high subgroup.  I would like to highlight 3 key takeaways from this abstract. First, KIM-1 high level was associated with significantly worse DFS with a hazard ratio of 1.75. Second, patients in the KIM-1 high subgroup receiving atezolizumab had a 28% reduction in the risk of recurrence or death compared to those receiving placebo, while those in the KIM-1 low subgroup had comparable outcomes across both treatment arms. Third, patients in the KIM-1 high subgroup receiving atezolizumab were significantly less likely to experience an on-treatment increase in KIM-1 levels, which was associated with worse DFS in both high and low KIM-1 subgroups, regardless of treatment arm. Thus, these findings support the use of KIM-1 as both a predictive and prognostic biomarker in patients with RCC. Dr. Neeraj Agarwal: Yes, Rana, this is amazing data! I would like to add that these results warrant larger and, ideally, prospective studies to validate the utility of KIM-1 as a noninvasive biomarker for identifying minimal residual disease after nephrectomy and for predicting outcomes to immune checkpoint inhibitors. Dr. Rana McKay: Also, in the field of biomarkers, 2 abstracts interrogating different biomarkers in a different setting, so in patients with advanced or metastatic RCC were presented. Neeraj, could you tell us more about these abstracts? Dr. Neeraj Agarwal: Of course! I think you are referring to Abstracts 4504 and 4505. In abstract 4504, Dr. Toni Choueiri and colleagues sought to assess the clinical implications of different biomarkers in the CLEAR trial, which was a randomized phase 3 trial that led to the approval of the combination of pembrolizumab plus lenvatinib in the first-line mRCC setting. On the other hand, in abstract 4505, Dr. Brian Rini presented biomarker results in KEYNOTE-426, which was also a randomized phase 3 trial based on which the combination of pembrolizumab plus axitinib was approved in patients with mRCC. The authors in both trials sought to investigate the role of biomarkers in predicting treatment outcomes from 3 different angles. Starting with PD-L1 expression, the superiority of the combination arms over sunitinib was not impacted by PD-L1 status in both trials. Moving on to RCC driver gene mutations on whole exome sequencing, such as VHL, SETD2, PBRM1, and BAP1, ICI combination therapies improved outcomes regardless of mutation gene status, and this improvement was statistically significant with PBRM1 mutations in KEYNOTE-426 compared to wild-type PBRM1, but this did not replicate in the CLEAR trial. Finally, using transcriptomic signatures derived from RCC trials, especially the IMmotion 151 and JAVELIN Renal 101 trials, where 7 clusters or molecular subtypes were identified, the combination arms outperformed sunitinib in all clusters in both trials and the magnitude of this benefit differed across clusters.  Dr. Rana McKay: Thank you for this very interesting summary and comparison of the results of these 2 abstracts. These findings support the use of ICI-based combinations in all patients with mRCC as a first-line option. Although these abstracts could not identify specific biomarkers that could guide us clinicians in treatment selection, they provide very interesting biological insights on these molecular biomarkers that are, however, not yet clinically actionable. Dr. Neeraj Agarwal: Very interesting point, Rana. Moving on to prostate cancer, let's start with abstract LBA5000 titled, “Cabazitaxel with abiraterone versus abiraterone alone randomized trial for extensive disease following docetaxel: The CHAARTED2 trial of the ECOG-ACRIN Cancer Research Group (EA8153).” Rana, what is your takeaway on this abstract? Dr. Rana McKay: As a reminder to our audience, the CHAARTED2 trial was a randomized open-label phase 2 study that compared the combination of cabazitaxel and abiraterone to abiraterone alone in patients with mCRPC previously treated with ADT plus docetaxel in the hormone-sensitive setting. The primary endpoint was progression-free survival. After a median follow-up of 47.3 months, Dr. Christos Kyriakopoulos and colleagues reported in LBA5000 that patients receiving the combination of cabazitaxel plus abiraterone had a 27% reduction in the risk of progression or death. However, there was no significant difference in overall survival between the two arms, with a median OS of 25 months in the cabazitaxel+abiraterone arm and 26.9 months in the abiraterone arm, although the study was underpowered for this endpoint. Regarding the toxicity profile, the combination of cabazitaxel and abiraterone was overall well tolerated with more cytopenias, as expected.  Dr. Neeraj Agarwal: Very nice summary of this abstract, Rana. I would like to add that the treatment landscape of patients with mHSPC has evolved since the design of the study and now includes combination therapies of ADT + ARPI with or without docetaxel, and ADT + docetaxel is no longer a standard of care, which limits the applicability of these results in clinical practice today.  Dr. Rana McKay: Excellent point, Neeraj. Let's discuss Abstract 5001, titled “CYCLONE 2: A phase 3 study of abemaciclib with abiraterone in patients with metastatic castration-resistant prostate cancer”. Dr. Neeraj Agarwal: Sure! In the abstract featured at ASCO24, Dr. Matthew Smith and colleagues report the primary results of the CYCLONE 2 trial, which was a randomized phase 2/3 study that investigated the combination of abemaciclib plus abiraterone versus abiraterone monotherapy in patients with mCRPC. Stratification factors included radiographic progression at study entry, presence of measurable disease, and prior docetaxel for mHSPC. Part 1 of the study established the recommended phase 2 dose of abemaciclib at 200 mg twice daily. In part 2, patients were randomized to placebo or abemaciclib, and an adaptive interim analysis using prespecified criteria was performed and recommended the expansion of the study to part 3. The primary endpoint was investigator-assessed radiographic progression-free survival by RECIST 1.1 and PCWG3 criteria in the intention-to-treat population. At the time of the primary analysis, adding abemaciclib to abiraterone did not improve rPFS, with a hazard ratio of 0.83. The median rPFS was 22 months for the combination arm and 20.3 months for the abiraterone arm. The combination was well tolerated, and the safety profile was consistent with the known adverse events. Dr. Rana McKay: So, the addition of abemaciclib to abiraterone did not improve outcomes in patients with mCRPC. These findings suggest that no further investigation is warranted for abemaciclib or CDK4/6 inhibitors in biomarker-unselected patients with prostate cancer.  Dr. Neeraj Agarwal: Rana, what's your take-home message on Abstract 5006, titled “Health-related quality of life results from PRESTO (AFT-19), a phase 3 randomized trial of intensification of androgen blockade in patients with high-risk biochemically relapsed castration sensitive prostate cancer”? Dr. Rana McKay: So, as a reminder to our audience, the PRESTO trial was a randomized phase 3 study that assessed the effects of intensified androgen receptor blockade in patients with biochemically recurrent prostate cancer following local therapies. Patients with a PSA doubling time of less than 9 months and no evidence of metastatic disease were randomized to receive either 52 weeks of ADT alone, ADT plus apalutamide, or ADT plus apalutamide plus abiraterone. In their paper published earlier this year in the Journal of Clinical Oncology, the authors showed that patients receiving ADT plus apalutamide with or without abiraterone had significantly longer PSA-progression-free survival than those receiving ADT alone. In the oral presentation featured at ASCO24, Dr. Ronald Chen and colleagues report health-related quality of life outcomes that were assessed using various questionnaires or scales at baseline, at cycle 7, which is around 6 months on treatment, and at the end of treatment. Results showed that this intensified approach with apalutamide did not significantly increase severe adverse events, did not lengthen the time to testosterone recovery, and did not meaningfully increase common treatment-related symptoms such as hormonal symptoms, sexual dysfunction, hot flash interference, and fatigue. Importantly, additional intensification with abiraterone did not further improve PSA-PFS but did increase the rate of serious adverse events, lengthened the time to testosterone recovery, and increased hot flash interference.  Dr. Neeraj Agarwal: So, in conclusion, the PRESTO trial supports using intensified androgen blockade with apalutamide to improve PSA-PFS in patients with high-risk biochemically recurrent prostate cancer without compromising health-related quality of life. However, adding abiraterone did not offer additional benefits and increased side effects.  Dr. Rana McKay: Let's move on to LBA5002 titled, “A randomized, double-blind, placebo-controlled trial of metformin in reducing progression among men on expectant management for low-risk prostate cancer: The MAST (Metformin Active Surveillance Trial) study.” Would you like to share your insights on this abstract with our listeners? Dr. Neeraj Agarwal: Absolutely. MAST was a randomized, double-blinded, placebo-controlled trial that investigated the impact of metformin on the progression of low-risk localized prostate cancer in patients choosing to undergo active surveillance. Eligible patients had biopsy-proven, low-risk, localized prostate cancer diagnosed within the past 6 months, characterized by a Gleason score of less than 6 observed in less than one-third of the total cores, less than 50% positivity in any one core, a PSA level of less than 10 ng/ml, and a clinical-stage between T1c and T2a. Patients were randomized in a 1:1 ratio to receive either metformin 850 mg twice daily or placebo for three years. All patients underwent repeat prostate biopsy at 18 and 36 months. The primary endpoint was time to progression, defined as the earliest occurrence of primary prostate cancer therapy, such as prostatectomy, radiation, hormonal therapy, or pathological progression on subsequent biopsies, which was defined as more than 1/3 of total cores involved, at least 50% of any one core involved, or Gleason pattern 4 or higher. The study included 407 patients, with 204 receiving metformin and 203 receiving a placebo. Results presented by Dr. Anthony Joshua showed no statistically significant difference in progression-free survival, including therapeutic and pathologic progression, with an unadjusted hazard ratio of 1.08.  Interestingly, there was a signal that patients with a BMI more than 30 had a detriment to taking metformin with a higher risk of progression compared to those receiving placebo with an unadjusted HR of 2.39 and a p-value of 0.01. Dr. Rana McKay: I would like to add that this study showed that metformin use does not prevent the progression of low-risk localized prostate cancer on active surveillance and could represent a potential detriment for patients with high BMI at study entry. Dr. Neeraj Agarwal: Yes, Rana, I concur. Any final remarks before we conclude today's podcast? Dr. Rana McKay:  Thank you, Neeraj; it's been wonderful being here with you today and you having me on the podcast to highlight these important advances and the amazing work that many investigators are conducting and the patients who were involved in the context of these trials. It's really excellent to see these updated results.   Dr. Neeraj Agarwal: Before we wrap up this podcast, I would like to say that we have reviewed a selection of abstracts addressing prostate, bladder, and kidney cancer, which are significantly impacting our medical practices now and in the near future. Rana, thank you for sharing your insights today. These updates are undoubtedly exciting for the entire GU oncology community, and we greatly appreciate your valuable contribution to the discussion.

Dr. Neeraj Agarwal and Dr. Jeanny Aragon-Ching discuss promising combination therapies and other compelling advances in genitourinary cancers in advance of the 2024 ASCO Annual Meeting. TRANSCRIPT Dr. Neeraj Agarwal: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, your guest host of the ASCO Daily News Podcast today. I'm the director of the Genitourinary Oncology Program and a professor of medicine at the University of Utah Huntsman Cancer Institute, and editor-in-chief of the ASCO Daily News. I'm delighted to be joined by Dr. Jeanny Aragon-Ching, a GU medical oncologist and the clinical program director of genitourinary cancers at the Inova Schar Cancer Institute in Virginia. Today, we will be discussing some key abstracts in GU oncology that will be featured at the 2024 ASCO Annual Meeting.  Our full disclosures are available in the transcript of this episode. Jeanny, it's great to have you on the podcast. Dr. Jeanny Aragon-Ching: Thank you so much, Dr. Agarwal. It's a pleasure to be here. Dr. Neeraj Agarwal: So, Jeanny, let's start with some bladder cancer abstracts. Could you tell us about the Abstract 4509 titled, “Characterization of Complete Responders to Nivolumab plus Gemcitabine Cisplatin versus Gemcitabine Cisplatin Alone in Patients with Lymph Node Only Metastatic Urothelial Carcinoma from the CheckMate 901 Trial.”  Dr. Jeanny Aragon-Ching: Of course, Neeraj, I would be delighted to. First, I would like to remind our listeners that the CheckMate 901 trial was a randomized, open-label, phase 3 study, in which this particular sub-study looked at cisplatin-eligible patients with previously untreated, unresectable, or metastatic urothelial carcinoma who were assigned to receive the combination of gemcitabine and cisplatin, followed by up to 2 years of nivolumab or placebo. Based on the data presented at ESMO 2023 and subsequently published in the New England Journal of Medicine, which shows significantly improved progression-free survival and overall survival in patients receiving the combination of gemcitabine, cisplatin, and nivolumab, this regimen was approved in March 2024 as a first-line therapy for patients with unresectable or metastatic urothelial carcinoma.  In the abstract that will be featured at ASCO this year, Dr. Matt Galsky and colleagues present a post-hoc analysis that aims to characterize a subset of patients with complete response as well as those with lymph node-only metastatic disease. In patients receiving the experimental treatment, 21.7% achieved a complete response, while 11.8% of the patients in the control arm achieved a complete response.  Among these complete responders, around 52% had lymph- node-only disease in both arms. Furthermore, when characterizing the subgroup of patients with lymph-node-only disease, those receiving the combination of gemcitabine-cisplatin plus nivolumab had a 62% reduction in the risk of progression or death and a 42% reduction in the risk of death compared to those treated with gemcitabine-cisplatin alone.  The median overall survival in the experimental arm in this subgroup was around 46.3 months, while it was only 24.9 months in the control arm. The ORR in patients with lymph-node-only disease receiving gem-cis plus nivo was about 81.5% compared to 64.3% in those treated with gem-cis alone. Dr. Neeraj Agarwal: Thank you, Jeanny, for the excellent summary of this abstract. We can say that nivolumab plus gemcitabine-cisplatin induced durable disease control and clinically meaningful improvements in OS and PFS compared to gem-cis alone in patients with lymph- node-only metastasis, and deserves to be considered as one of the options for these patients.  In a similar first-line metastatic urothelial carcinoma setting, Abstract 4502, also reported data on a recently approved combination of enfortumab vedotin and pembrolizumab. Can you tell us more about this abstract, Jeanny? Dr. Jeanny Aragon-Ching: Sure, Neeraj. So, as quick reminder to our audience, this regimen was tested in the EV-302 phase 3 trial, where patients with previously untreated, locally advanced or metastatic urothelial carcinoma were randomized to receive enfortumab vedotin, plus pembrolizumab or gemcitabine plus either cisplatin or carboplatin. These data were also first presented at ESMO 2023 and subsequently published in the New England Journal of Medicine. They showed that this immune based combination significantly improved both progression free survival and overall survival, which were the primary endpoints compared to chemotherapy. In this abstract, Dr. Shilpa Gupta from the Cleveland Clinic and colleagues present the results of patient reported outcomes based on quality-of-life questionnaires in this trial.  Time to pain progression and time to confirm deterioration were numerically longer in patients treated with EV plus pembro, and patients with moderate to severe pain at baseline receiving this combination had a meaningful improvement in the Brief Pain Inventory Short-Form worst pain from week 3 through 26. Dr. Neeraj Agarwal: Thank you, Jeanny. This means that patients treated with EV plus pembro did not only have improved survival compared with platinum-based chemotherapy, but also improvement in their quality-of-life and functioning, further supporting the value of this combination for patients with locally advanced or metastatic urothelial carcinoma. This is terrific news for all of our patients.   Before we wrap up the bladder cancer section, would you like to tell our listeners about Abstract 4565, which provides the data on the efficacy of trastuzumab deruxtecan in patients with bladder cancer? Dr. Jeanny Aragon-Ching: Yes, Neeraj; this is timely given the recent FDA approval, which we will talk about. The abstract is titled, “Efficacy and Safety of Trastuzumab Deruxtecan in Patients with HER2 Expressing Solid Tumors: Results from the Bladder Cohort of the DESTINY-PanTumor02 Study.” And as a quick reminder, the DESTINY-PanTumor02 was a phase 2 open-label study where trastuzumab deruxtecan, an antibody-drug conjugate targeting HER2 expression on cancer cells, was evaluated in patients with HER2-expressing locally advanced or metastatic disease who previously received systemic treatment or who had no other treatment options. The expression of HER2 was evaluated on immunohistochemistry by local or central testing.   The primary endpoint was confirmed objective response rate by investigator assessment. Secondary endpoints included duration of response, progression free survival, disease control rate, and safety. The primary analysis, which was published in the Journal of Clinical Oncology, showed an ORR of 37.1% and responses across all cohorts and the median duration of response was 11.3 months. Based on these results, fam-trastuzumab deruxtecan-nxki was just granted accelerated FDA approval for unresectable or metastatic HER2-positive solid tumors in April 2024.  So, back to this abstract; Dr. Wysocki and colleagues report the results of the bladder cancer cohort. This study included 41 patients with urothelial cancer and at a median follow up of around 12.6 months, the objective response rate among these patients was 39%, the median PFS was 7 months, and the duration of response median was 8.7 months. The disease control rate at 12 weeks was around 71%. Regarding the safety profile, 41.5% of patients experienced grade ≥3 drug related adverse events and interstitial lung disease or pneumonitis did occur in about 4 patients. Although there was no statistical comparison between different groups, the ORR was numerically highest among the HER2 3+ group with 56.3%.  Dr. Neeraj Agarwal: Thank you, Jeanny. So, these data support consideration of trastuzumab deruxtecan as a salvage therapy option for pre-treated patients with HER2 expressing urothelial cancers and show that we are extending our treatment options to include therapies with novel mechanisms of action. This is definitely exciting news for patients with bladder cancer. Dr. Jeanny Aragon-Ching: Yes, absolutely, Neeraj. Now, let's switch gears a bit to prostate cancer. Could you tell us about Abstract 5005 which is titled, “EMBARK Post Hoc Analysis of Impact of Treatment Suspension on Health Quality-of-Life?” Dr. Neeraj Agarwal: Of course, I'd be happy to. So, enzalutamide was recently granted FDA approval for the treatment of patients with non-metastatic castration-sensitive prostate cancer with biochemical recurrence at high-risk of metastasis, based on the results of the EMBARK trial, which was a phase 3 study where patients with high-risk biochemical recurrence were randomized to receive either enzalutamide with leuprolide, enzalutamide monotherapy, or placebo plus leuprolide. The primary endpoint was metastasis-free survival with secondary endpoints including overall survival and safety.  Results showed that patients receiving enzalutamide alone or enzalutamide plus leuprolide had significantly improved metastasis-free survival compared to those treated with leuprolide alone while preserving health-related quality-of-life.   One important aspect in the design of the trial was that patients who achieved undetectable PSA at week 37 underwent treatment suspension. The treatment was resumed if PSA rose to more than 2 ng/ml for patients who underwent radical proctectomy or when PSA rose to more than 5 ng/ml for those who did not undergo surgery.  In this abstract, Dr. Stephen Freedland and colleagues present a post-hoc analysis of health-related quality-of-life outcomes after treatment suspension between weeks 37 and 205. They found that treatment was suspended in 90.9% of patients receiving enzalutamide plus leuprolide, 85.9% of those receiving enzalutamide monotherapy, and 67.8% of those receiving leuprolide monotherapy. Among those patients who stayed on treatment suspension, a trend toward numerical improvement in health-related quality-of-life after week 37 was seen in all 3 arms and this reached clinically meaningful threshold at week 205 in pain questionnaires, physical well-being, urinary and bowel symptoms. For hormonal treatment side effects, all arms reached clinically meaningful improvement at the subsequent assessments of week 49 to week 97. However, patients slowly deteriorated, with clinically meaningful deterioration at week 205 relative to week 37 in patients receiving the combination of enzalutamide and leuprolide and those treated with leuprolide.    Concerning sexual activity, a clinically meaningful improvement was reported only in patients receiving enzalutamide plus leuprolide, possibly because sexual function was better preserved prior to suspension in the enzalutamide monotherapy arm and thus there was less opportunity for “improvement” while on suspension.  Dr. Jeanny Aragon-Ching: Thank you, Neeraj, for this great summary. This analysis confirms that treatment suspension in good responders might lead to a clinically meaningful improvements in health-related quality-of-life.   Now, moving on to patients with metastatic castration-resistant prostate cancer, what can you tell us, about Abstract 5008 titled, “Baseline ctDNA analyses and associations with outcomes in taxane-naive patients with mCRPC treated with 177Lu-PSMA-617 versus change of ARPI in PSMAfore”?  Dr. Neeraj Agarwal: Sure, Jeanny. The PSMAfore trial was a phase 3 study that compared the efficacy of 177Lu-PSMA-617 versus an ARPI switch in patients with mCRPC and prior progression on a first ARPI, and not previously exposed to docetaxel chemotherapy. The primary endpoint was rPFS and OS was an important secondary endpoint. The primary analysis presented at ESMO 2023 showed a significantly prolonged rPFS in patients receiving lutetium. In the abstract that will be featured at the 2024 ASCO Annual Meeting, Dr. Johann De Bono and colleagues present an exploratory analysis regarding the associations between baseline circulating tumor DNA and outcomes.  ctDNA fraction was evaluated in all samples as well as alterations in key prostate cancer drivers prevalent in more than 10% of participants.  The investigators sought to interrogate the association of ctDNA fraction or alterations with rPFS, PSA response, and RECIST response at data cutoff. They showed that median rPFS was significantly shorter in patients with a ctDNA fraction >1% compared to those with a fraction < 1% regardless of the treatment arm. Furthermore, ctDNA fraction >1% was also associated with worst RECIST response and PSA50 response. Regarding prostate cancer drivers, median rPFS was significantly shorter in patients with alterations in the AR, TP53 or PTEN in both treatment arms. There was no significant association between ctDNA alterations and PSA or objective responses. Dr. Jeanny Aragon-Ching: Thank you, Neeraj. So, these results show that the presence of a ctDNA fraction >1% or alterations in AR, P53 and PTEN were all associated with worse outcomes regardless of treatment with lutetium or change in the ARPI. These data are definitely important for counseling and prognostication of patients in the clinic and may guide the design of future clinical trials. Let's move on to kidney cancer. Neeraj, do you have any updates for us?  Dr. Neeraj Agarwal:  Sure. In Abstract 4512 titled, “A Multi-institution Analysis of Outcomes with First-Line Therapy for 99 Patients with Metastatic Chromophobe Renal Cell Carcinoma,” Dr. Sahil Doshi and colleagues present a retrospective, multi-institutional study comparing survival outcomes, including time-to-treatment failure and overall survival, between different first-line treatment options in patients with metastatic chromophobe renal cell carcinoma, where limited clinical trial data exists to guide systemic therapy. They categorized patients into 4 treatment groups: and immune checkpoint inhibitors + targeted therapy doublets (such as ICI VEGF TKI); pure immune checkpoint inhibitor monotherapy and doublets (such as ipilimumab plus nivolumab); targeted therapy doublets (such as lenvatinib plus everolimus), and targeted monotherapy (such as sunitinib).  They identified 99 patients, of whom 54 patients received targeted monotherapy, 17 received ICI VEGF-TKI, 14 received targeted doublet, and 14 patients received only ICI therapies. So the patients treated with any doublet containing a targeted agent had a 52% decrease in the risk of treatment failure and a 44% decrease in the risk of death compared to those treated with targeted monotherapy. The median time to treatment failure was 15 months with IO-targeted doublet, and the median overall survival was 56 months. Dr. Jeanny Aragon-Ching: Thank you, Neeraj. So, these results show that targeted doublet regimens resulted in a longer time to treatment failure and overall survival compared to any monotherapy in patients with chromophobe metastatic RCC and definitely provides valuable insights on treatment selection, albeit I would say there's still a small number of patients that were included in this retrospective analysis. Dr. Neeraj Agarwal: I completely agree this is a relatively small number of patients, but I decided to highlight the abstract given how rare the cancer is, and it is highly unlikely that we'll see large randomized clinical trials in patients with metastatic chromophobe renal cell carcinoma.  So, before we wrap up the podcast, what would you like to tell us about Abstract 5009 which is titled, “A Phase II Trial of Pembrolizumab Platinum Based Chemotherapy as First Line Systemic Therapy in Advanced Penile Cancer: HERCULES (LACOG 0218) Trial.” Dr. Jeanny Aragon-Ching: I'm glad you brought this up, Neeraj. As our listeners may know, advanced penile squamous cell carcinoma has a poor prognosis with limited treatment options. From this perspective, the results of the LACOG 0218 trial are very important. As you mentioned, this was a phase 2 single-arm study evaluating the addition of pembrolizumab to platinum-based chemotherapy as first-line treatment in patients with metastatic or locally advanced penile squamous cell carcinoma not amenable to curative therapy. Patients enrolled received chemotherapy, namely 5-Fluorouracil with cisplatin or carboplatin and pembrolizumab 200 mg IV every 3 weeks for 6 cycles, followed by pembrolizumab 200 mg IV every 3 weeks up to 34 cycles. The primary endpoint was confirmed overall response rate by investigator assessment.  In the 33 patients eligible for the efficacy analysis, the confirmed ORR by investigator assessment was 39.4% and included one complete response and 12 partial responses. The confirmed ORR was 75% in patients with high TMB and 55.6% in patients positive for HPV16, making TMB and HPV16 potential predictive biomarkers for efficacy in this study. Concerning the toxicity profile, any grade treatment-related adverse events were reported in around 92% of patients, and grade 3 or more treatment-related adverse events occurred in 51% of patients. 10.8% of patients discontinued treatment due to adverse events.  Dr. Neeraj Agarwal: Thank you, Jeanny. I would like to add that HERCULES is the first trial to demonstrate the efficacy of an immune checkpoint inhibitor in advanced penile squamous cell carcinoma with a manageable safety profile. Thus, the combination of ICI with platinum-based chemotherapy is a promising treatment for advanced penile squamous cell carcinoma and warrants further investigation.  Dr. Jeanny Aragon-Ching: I agree, Neeraj. Any final remarks before we conclude today's podcast? Dr. Neeraj Agarwal: Jeanny, I really want to thank you for your participation and valuable insights. Your contributions are always appreciated, and I sincerely thank you for taking the time to join us today. Dr. Jeanny Aragon-Ching: Thank you, Neeraj. It was a pleasure.  Dr. Neeraj Agarwal:  As we bring this podcast to an end, I would like to acknowledge the significant advances happening in the treatment of patients with genitourinary cancers. During our upcoming 2024 ASCO Annual Meeting, there will be an array of different studies featuring practice-changing data presented by researchers and physicians from around the globe. I urge our listeners to not only participate in this event to celebrate these achievements, but to also play a role in sharing these cutting-edge data with healthcare professionals worldwide. Through our collective efforts, we can surely optimize the benefits of patients on a global scale.   And thank you to our listeners for joining us today.

Drs. Neeraj Agarwal and Todd Morgan discuss CONTACT-02, KEYNOTE-564, CheckMate-67T, and other notable studies featured at the 2024 ASCO Genitourinary Cancers Symposium, as well as additional key abstracts in prostate, kidney, and bladder cancers that will significantly influence clinical practice. TRANSCRIPT Dr. Neeraj Agarwal: Hello, and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, the director of the Genitourinary Oncology Program and professor of medicine at the Huntsman Cancer Institute at the University of Utah, and editor-in-chief of ASCO Daily News. Today, we'll be discussing practice-changing abstracts and other key advances in GU oncology featured at the 2024 ASCO Genitourinary Cancers Symposium. Joining me for this discussion is Dr. Todd Morgan, the chair of this year's ASCO GU. Dr. Morgan is a urologic surgeon, chief of urologic oncology at Michigan Medicine, and a professor of urology at the University of Michigan. Our full disclosures are available in the transcript of this episode, and the disclosures of all guests on the podcast can be found at asco.org/DNpod. Todd, thank you for joining us today. Dr. Todd Morgan: Thanks so much, Neeraj. It's an honor to be here and I'm just thrilled to be able to do this with you. Dr. Neeraj Agarwal: Thank you. So, the GU meeting showcased significant advancements across the spectrum of GU malignancies. Can you tell us about the hot topics that captured the headlines this year? What did you find exciting this year at the ASCO GU Symposium? Dr. Todd Morgan: The theme of this year's meeting was "20 Years of Advancing Science and Transforming Patient Care," and this reflected ASCO GU's incredible milestone in GU cancer research over the last 2 decades. We were thrilled to welcome over 5,200 attendees from over 70 countries, and, believe it or not, there were more than 875 abstract submissions, compared to more than 300 in the meeting's first year. Most of the participants were present in person and that was fantastic. It enabled great networking opportunities and opportunities for experts, trainees, and mentees to exchange knowledge and ideas. Without a doubt, ASCO GU remains the annual meeting in our field, and it's amazing to hear the breadth and depth of the state-of-the-art science that's presented at this meeting, and so much of it impacts patient care the second that you return home. Additionally, the meeting's focus on diversity and interactivity, networking, multidisciplinary collaboration, and evidence-based care were absolutely phenomenal from my standpoint. We had a lunch session for women's networking that was a huge success—the first time we've done that. The keynote lecture by Dr. Cheryl Lee that talked about ensuring adequate representation in clinical trials was a huge hit, and we had tremendous positive feedback from that lecture. There were also multiple featured sessions on different diagnostic and therapeutic challenges in localized, recurrent, and advanced GU cancers. And, Neeraj, my personal favorite during the symposium is always the Trainee and Early-Career Networking Luncheon on the first day and then the additional networking luncheons on the 2 following days. I had great conversations with a ton of trainees and junior faculty, and I feel so fortunate for the opportunity to get to know the future superstars in our field. So I'd like to kick it back to you for a second because the first day started with a focus on prostate cancer and some of the key clinical trials. A great example is Abstract 17, which was the second oral presentation delivered, and really congratulations to you, Neeraj, on sharing the exciting data from the CONTACT-02 trial which we were eagerly awaiting. And I'd love to get your thoughts on the data that you presented. Could you tell us more about that trial? Dr. Neeraj Agarwal: Yes, Todd, I agree with you. It was such an exciting conference overall, and thank you for your leadership of this conference. So let's talk about the CONTACT-02 trial. It was a phase 3 randomized trial assessing the combination of cabozantinib and atezolizumab versus a second NHT in patients with metastatic castration-resistant prostate cancer after progression on one NHT. This patient population had to have extrapelvic soft tissue metastases, which could be liver metastases, lung metastases, or lymph nodal metastases, and about up to a quarter of patients had liver metastases. And overall, this was a high-risk patient population which was randomized to, as I said, cabozantinib plus atezolizumab versus a second line NHT. And these patients had received a prior NHT, mostly in the mCRPC setting.  The co- or dual primary endpoints were overall survival and progression-free survival (PFS). And a unique thing was that PFS was assessed only by RECIST 1.1 because, as per our discussions with regulatory authorities, the trial was focused on soft tissue metastases because of questions in the past that cabozantinib can affect bone lesions in an artifactual fashion, possibly concerns. That's why the PCWG 3 criteria were not used as the primary endpoint, but, of course, indeed used as another key endpoint, so we have information on both. Anyway, coming back to the endpoint 1:1 randomization. The randomization was stratified by presence or absence of liver metastases, prior docetaxel chemotherapy, and the setting in which NHT was given (mCSPC or CRPC). The PFS or primary endpoint was significantly improved with a 35% reduction in risk of progression or death with the cabozantinib-atezolizumab combination versus second NHT. And there was a trend for overall survival, with a hazard ratio of 0.79 favoring the cabozantinib-atezolizumab combination. Interestingly, all subgroups benefitted, regardless of age, region, site of metastases, but we decided to choose three clinical subgroups of interest such as patients with liver metastases, patients with prior docetaxel chemotherapy in the castration-sensitive setting, and bone metastases, and all these subgroups seemed to be benefitting with the strongest signal in the liver metastasis subgroup, with a 57% reduction in risk of progression or death, which I would argue we have never seen with any combination or any regimen in the metastatic prostate cancer setting yet, barring some targeted therapies in very selected patients. But overall, across the non-biomarker-selected patients, we have never seen this kind of signal. Toxicity — no discussion is complete without discussing toxicity, so I would like to highlight that. Safety signal — there were no new safety signals. The most common grade 3-4 adverse events were hypertension in 7%, anemia in 6%, which were similar in both arms, and, of course, diarrhea and fatigue in 4% each. And if we look at the secondary endpoints, such as time to chemotherapy and time to symptomatic skeletal events, they tended to favor the cabozantinib-atezolizumab. To sum it up, cabozantinib-atezolizumab showed a significant PFS benefit, with a 35% reduction in risk of progression or death, with a trend for overall survival in this patient population with an unmet need. So thank you so much, Todd, for allowing me to summarize the results of this trial. Dr. Todd Morgan: Yeah, wow. That's so impressive, and not surprising that you could so fluidly go right through all that data. Amazing. We heard some discussion of the NHT control arm in this trial. Could you discuss that for a bit? Because it obviously has implications on the similar control arm of other ongoing trials in this setting. Dr. Neeraj Agarwal: Absolutely. Pretty much all trials, every trial which has recently been reported or started in metastatic castrate-resistant prostate cancer have a similar second NHT arm. Whether there were multiple immunotherapy trials which we have just reported, or new trials which are starting or just started enrolling patients. And the reason for that is no randomized trial has ever shown superiority of docetaxel chemotherapy over a second NHT after failure of prior NHT in the mCRPC setting. That's number one. If you look at NHT as a control, it is accepted by health authorities globally with multiple recent trials which are just starting also having NHDR and it would not have been possible without the approval of global regulatory authorities across the world.  Then, if you look at the recently reported trial in the mCRPC setting with prior treatment with an NHT, there is an indication that chemotherapy may not be superior to NHT. For example, in the KEYNOTE-641 trial in patients with mCRPC with prior NHT, randomizing patients to enzalutamide plus pembrolizumab versus enzalutamide, the median PFS with enzalutamide was 9 months. This is very similar with docetaxel in patients randomized to docetaxel plus pembrolizumab versus docetaxel; the median PFS with docetaxel is 8 months or 8.3 months. And lastly, if you really want to have a comparison of chemotherapy with NHT which has been done after progression on NHT and docetaxel chemotherapy, so later line of mCRPC setting, that is the CARD trial, as you can imagine, cabazitaxel versus NHT, especially in patients with visceral metastasis, which was the point of discussion. For example, people may not feel comfortable randomizing patients to NHT compared to taxane. The hazard ratio for PFS supporting cabazitaxel was 0.79, so almost a 0.80 PFS hazard ratio, which we have never seen turning out to be a clinically significant benefit. So, if you combine all these data together, I think it was absolutely acceptable to us as investigators to have a second NHT as the control arm. And of course, when we are consenting the patient, we have to keep alternatives in mind, and we do talk about those alternatives with the patients. And if alternatives seem more applicable, we should not be talking to patients about those clinical trials or a given clinical trial in the clinic. I'm glad you brought this up, Todd, because this control NHT arm is not an issue with this trial, but all trials which should be presented in GU ASCO in the future meetings in the coming years. So, thank you. Dr. Todd Morgan: Yeah, thank you. It's such an important topic and controversy at some level, but it's a difficult problem to think about and obviously highly relevant to all the trials that we're looking at. Congrats again on that trial, that's tremendous. There was another important randomized phase 3 trial and it covers radiotherapy in patients with high-risk localized prostate cancer. Can you give us your insights on that one? Dr. Neeraj Agarwal: Yeah, Todd, I think you are referring to LBA259, titled "Long-term Results of Dose Escalation of Radiation Therapy from 70 Gy to 80 Gy Combined with Long-term Androgen Deprivation Therapy in High-risk Prostate Cancer: The GETUG-AFU 18 Randomized Trial." As you mentioned, in this randomized phase 3 trial, Dr. Christophe Hennequin and colleagues randomized patients with high-risk prostate cancer, which means they had to have either clinical stage T3 or T4 disease, or PSA ≥20 nanograms per milliliter, or a Gleason score between 8 and 10. These patients were randomized to receive ADT for 3 years combined with either dose-escalated intensity-modulated radiotherapy. So, I'd like to highlight, this was in the context of IMRT in the dose of 80 Gy or a conventional dose of 70 Gy. Now, you can argue that more people are using more than 70 Gy nowadays, but across the world, the conventional dose is still considered 70 Gy. So, 80 Gy versus 70 Gy were tested. Patients also had to have negative lymph node status on CT scans and MRI. The primary endpoint was biochemical progression-free survival or clinical progression-free survival at 5 years following the ASTRO Phoenix definition. Secondary endpoints – and these are quite important secondary endpoints – include overall survival, acute and late toxicity, and quality of life. The best part is that this trial met its primary endpoint with a 44% reduction in risk of biochemical or clinical progression or death in the dose-escalation radiotherapy arm compared with the conventional radiotherapy arm. Interestingly, a significant 52% improvement in prostate cancer-specific survival and a 39% improvement in overall survival was observed in the dose-escalated arm. So, 80 Gy continued to be superior to 70 Gy IMRT across the primary and secondary endpoints. Now, the best part is, regarding the toxicity profile, there was no significant difference between the 2 arms, with 78% of patients in the higher dose arm and 76% of patients in the conventional arm experiencing grade 2 or more toxicities. Dr. Todd Morgan: Great summary and really important, great news for our patients. Of course, it's a slightly different setting as it's high-risk localized prostate cancer. I checked in with our radiation oncologists at the University of Michigan after that [presentation] because I couldn't remember exactly where we are in terms of dose on these patients. And they were like, “Yeah, we've been doing 80 to 90 Gy for several years,” so it's great having this data to support that. And I think, as you said, the field at many centers has already moved that way. And again, the key takeaway from this abstract would be that IMRT, in combination with long-term androgen deprivation therapy, is effective and safe and increases not only the biochemical or clinical PFS rate, but also the cancer-specific survival and overall survival, again, in high-risk localized prostate cancer patients. And it does not appear to increase long-term toxicity. So really important. It'd be great to switch gears and discuss kidney cancer, if that's okay, and talk about some key abstracts in that field. What do you think? Dr. Neeraj Agarwal: There were so many exciting data in all cancers, which is amazing. So, Todd, could tell us about the LBA359, which I thought was one of the most impactful abstract presentations in the ASCO GU this year. It was titled, “Overall Survival Results from the Phase 3 KEYNOTE-564 Study of Adjuvant Pembrolizumab Versus Placebo for Treatment of Clear Cell Renal Cell Carcinoma (ccRCC)."   Dr. Todd Morgan: Yeah, this was a really big moment in our field, complete with a mid-presentation round of applause that was well deserved. And so this abstract was presented by Dr. Toni Choueiri from Dana-Farber Cancer Institute, and it included patients with clear cell renal cell carcinoma at intermediate high or high risk of recurrence, meaning that they had positive nodal disease or negative nodal disease with PT 2 and grade 4, or sarcomatoid features, or stage PT 3 or 4. These patients underwent nephrectomy with or without metastasectomy less than 12 weeks before randomization and had not received prior systemic therapy for clear cell RCC. Patients were randomized to receive either pembrolizumab 200 milligrams or placebo IV every three weeks for at least 17 cycles, or until disease recurrence, intolerable toxicity, or withdrawal of consent. Disease-free survival by investigator assessment was the primary endpoint, and overall survival was a key secondary endpoint. In this abstract, Dr. Choueiri and colleagues report results of the third prespecified interim analysis with a median follow-up of around 57 months in 496 patients receiving pembrolizumab and 498 patients receiving placebo. So, just as a reminder to the audience here, the first interim analysis reported at a median follow-up of 24 months and showed a significant reduction of 32% in the risk to recurrence or death in patients in the pembrolizumab arm. Then subsequently in November of 2021, the FDA approved pembrolizumab for the adjuvant treatment of patients with RCC who are at intermediate high or high risk of recurrence following nephrectomy or following nephrectomy and resection of metastatic lesions. At that time, though, overall survival data were still immature. So, at the third prespecified interim analysis with a median follow-up of around 57 months, pembrolizumab showed, for the first time in an adjuvant RCC setting, improved overall survival with a 38% reduction in the risk of death. The estimated OS rate at 48 months was 91.2% with pembrolizumab and 86% with placebo. Furthermore, the OS benefit was observed across key subgroups, including patients with non-metastatic disease, patients with metastatic but no evidence of disease, patients with PDL-1 combined positive score less than or greater than or equal to one, and patients with presence or absence of sarcomatoid features. In each of these subgroups, the forest plot looks really impressive. And the DFS benefit was similar to previously reported interim analyses with a hazard ratio of 0.72. Also, no new safety signals with pembrolizumab were observed so just tremendous data. Dr. Neeraj Agarwal: Thank you, Todd, for such a great summary of these very important results. So the key message from this abstract, as you said, is that after a median follow-up of around 57 months, which is a long follow-up, adjuvant pembrolizumab demonstrates a statistically significant and clinically meaningful improvement in overall survival versus placebo in patients with RCC at high risk of disease recurrence after surgery. And this is, by the way, the first phase 3 study to show improved overall survival with any adjuvant therapy in RCC. Basically, this means we should continue to use adjuvant pembrolizumab or at least bring it up in our discussion with our patients who are in a similar situation with high-risk RCC after surgery. So this is great news overall. Todd, there was another kidney cancer abstract, LBA360, which compared, interestingly, subcutaneous nivolumab with intravenous nivolumab in patients with metastatic renal cell carcinoma. Could you please give us your insight about this abstract?   Dr. Todd Morgan: Sure. Really interesting study. Really interesting data that were presented. So as you mentioned, CheckMate 67T was a multicenter, randomized, open-label phase three study led by Dr. Saby George and colleagues that evaluated pharmacokinetics and objective response rate non-inferiority of subcutaneous nivolumab versus IV nivolumab in patients with locally advanced or metastatic clear cell RCC. So patients with measurable disease that progressed during or after 1 to 2 prior systemic regimens and who did not receive a prior immuno-oncology treatment were randomized 1-1 to receive either subcutaneous nivolumab 1200 milligrams every 4 weeks or IV nivolumab 3 milligrams per kilogram every two weeks until disease progression, unacceptable toxicity, withdrawal of consent, completion of two years of treatment, or death. The coprimary pharmacokinetics endpoints for non-inferiority testing were time-average serum concentration over the first 28 days and minimum serum concentration at steady state determined by a population pharmacokinetics analysis. A key secondary endpoint was objective response rate by independent review. So in 248 patients receiving subcutaneous nivolumab and 247 patients receiving IV nivolumab, non-inferiority for the coprimary pharmacokinetics and key-powered secondary objective response rate endpoints were met. The relative risk ratio for objective response rate was 1.33. The median PFS by independent review was 7.23 months in the subcutaneous group and 5.65 months in the IV group. Treatment-related serious adverse events occurred in 6.5% of patients in each group, and study drug toxicity led to 3 deaths in the subcutaneous group and 1 death in the IV group. These results could support using subcutaneous nivolumab as a new option to improve healthcare efficiency, especially since the average injection time with subcutaneous nivolumab was less than 5 minutes. I think we all know what issues are going on in infusion beds across the country, including, I'm sure, your center and mine. Dr. Neeraj Agarwal: Yes, absolutely. I think this is great news for our patients, Todd. Thank you. This shows that we are not only improving therapeutic options and diagnostic tools, but maybe we're also on the right track towards more practical administration routes, assisting in addressing the treatment burden and improving the efficiencies of healthcare systems. We love to have this option available for our patients, especially those who are pressed for time. So, Todd, would you like to move on to bladder cancer now?  Dr. Todd Morgan: Yeah, Neeraj, that'll be fantastic. I'm sure listeners would love to hear more about LBA530. Could you tell us more about this one, Neeraj? Dr. Neeraj Agarwal: Of course. I think this abstract is titled "Enfortumab Vedotin in Combination with Pembrolizumab Versus Chemotherapy in Previously Untreated, Locally Advanced or Metastatic Urothelial Carcinoma: Subgroup Analysis Results from EV-302," which was a global phase three study and was presented by Dr. Michiel Van Der Heijden. As our audience may recall, the EV-302 trial was presented at the ESMO 2023 meeting by Dr Tom Powles and the results were very exciting where, for the first time, a combination outperformed traditional gemcitabine-cisplatin chemotherapy. In this trial, patients with previously untreated with metastatic advanced urothelial carcinoma were randomized 1-1 to receive a 3-week cycle of a combination of enfortumab vedotin, which, as we know, is an antibody-drug conjugate targeting nectin-4 expressed on the cancer cells and pembrolizumab, which is a PD-1 inhibitor, versus gemcitabine and cisplatin or carboplatin, which were, until recently, the standard of care in this setting, and continue to be so in many countries in the world. The combination of enfortumab and pembrolizumab reduced the risk of progression or death by 55% and reduced the risk of death by 53% in the overall population. So consistent decrease in the hazard ratios for PFS and OS, and consistent improvement in overall survival and PFS in that previously reported presentation in the ESMO 2023. Now, based on these results, this combination was recently approved by the FDA in December 2023 for patients with advanced or metastatic urothelial carcinoma. So now the abstract, which was presented at the ASCO GU 2024 meeting, reported the results of a prespecified subgroup analysis. Select secondary endpoints included objective responses, duration of response, and safety. In 442 patients receiving the combination of enfortumab vedotin plus pembrolizumab, and a similar number of patients receiving chemotherapy both PFS and OS were higher for the combination of EV and pembro among prespecified subgroups such as race, platinum eligibility, PDL-1 expression, metastatic site, involvement of the liver or kidney function. Interestingly, the combination of EV and pembro reduced the risk of death by 53% in patients with visceral metastasis and 54% in patients with node-only metastasis. The improvement in PFS seems to be consistent regardless of the site of metastasis. In patients with moderate to severe renal function, the risk of death was reduced by 50% in patients receiving combination therapy. This is one of the best findings of these results because we always face challenges in treating patients with suboptimal kidney function and we cannot use cisplatin. Overall, EV plus pembro continues to show superior efficacy compared to platinum-based regimens across subgroups across the subgroups across the site of metastasis regardless of kidney function and so on. Dr. Todd Morgan: Yeah, just amazing data. I love hearing you spell it out like that. So, thank you again for the opportunity for me to sit here with you and listen to you talk about these data. It's impressive that we have been able to expand our therapeutic arsenal for urothelial carcinoma with an immune-targeting regimen that can spare our patients potential side effects of chemotherapy. What would your final takeaway on this abstract be? Dr. Neeraj Agarwal: I agree with you, Todd. I would add that the OS benefit was consistently observed across these select prespecified subgroups, including those historically associated with poor prognosis. The results of this new analysis support the finding of primary results, which indicate that EV plus pembro is a potentially new standard of care for patients with newly diagnosed, locally advanced, or metastatic urothelial carcinoma. Before we wrap up the bladder cancer session and the podcast, Todd, could you please give us insights about LBA531? Dr. Todd Morgan: Yeah, absolutely. I loved getting to hear this abstract presented. This one is titled “Ambassador,” known as the AMBASSADOR trial aligns A031501, a phase 3 randomized adjuvant study of pembrolizumab in muscle-invasive and locally advanced urothelial carcinoma versus observation, that was presented by Dr. Andrea Apolo. It's an open-label, randomized, phase 3 trial that included patients with muscle-invasive urothelial carcinoma of the bladder, upper tract, or urethra. Eligible patients had pathologic tumor stage T2 or greater and/or positive pathologic nodal disease or positive margins at surgery following neoadjuvant chemotherapy, or patients with pathologic tumor stage T3 or greater and/or positive pathologic nodal disease or positive margins at surgery without prior neoadjuvant chemotherapy, and who were cisplatin ineligible or declined adjuvant cisplatin-based therapy. These patients were randomized one to one to either receive pembrolizumab 200 milligrams every 3 weeks for 1 year or observation. The dual primary endpoints were disease-free survival and overall survival. Secondary objectives included evaluation of DFS and OS in PDL-1 positive and negative patients and assessing safety. A total of 354 patients were enrolled to receive pembrolizumab and 348 to the observation arm, and 21% of the patients in the observation arm received a subsequent immune checkpoint inhibitor. At a median follow-up of 22.3 months for DFS, the median disease-free survival in the pembrolizumab arm was 29 months, while it was only 14 months in the observation arm with a hazard ratio of 0.69. At the interim analysis, OS data showed only a trend toward better outcomes in the pembrolizumab arm, which did not, however, reach statistical significance, with a median of 50.9 months in the pembrolizumab arm and 55.8 months in the observation arm with a hazard ratio of 0.98. These results could nevertheless have been impacted by the subsequent treatment of patients in the observation arm with an immune checkpoint inhibitor, especially after the FDA approval of nivolumab in 2021 for patients with muscle-invasive urothelial carcinoma, based on results of the CheckMate 274 trial. In terms of the safety profile, grade three or more adverse events occurred in 48.4% of patients in the pembrolizumab arm and 31.8% of patients in the observation arm. Dr. Neeraj Agarwal: That's great, Todd. This is such a great summary of this trial, and this is exciting news for our patients with muscle-invasive urothelial carcinoma. I'm hoping that pembrolizumab will be another option for our patients when we are discussing adjuvant immunotherapy in the clinic, moving forward very soon. With that, we have covered several abstracts addressing prostate, bladder, and kidney cancer, significantly influencing our medical practices, at least at the current moment or in the near future. Todd, thank you for sharing your insights today. These are undoubtedly exciting updates for all members of the GU oncology community, and we are grateful for your valuable contribution to the discussion. Many thanks. Dr. Todd Morgan: Thanks, for having me, Neeraj; this was really fun. I'm just really proud and excited to still be part of this field, to be part of the GU oncology field, and it continues to be exciting for all the folks who are coming up. Dr. Neeraj Agarwal: Indeed.

Drs. Neeraj Agarwal and Jeanny Aragon-Ching discuss several key abstracts to be presented at the 2024 ASCO GU Cancers Symposium, including sequencing versus upfront combination therapies for mCRPC in the BRCAAway study, updates on the CheckMate-9ER and CheckMate-214 trials in ccRCC, and a compelling real-world retrospective study in mUC of patients with FGFR2 and FGFR3 mutations. TRANSCRIPT Dr. Neeraj Agarwal: Hello, everyone, and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, your guest host of the podcast today. I am the director of the Genitourinary Oncology Program and a professor of medicine at the University of Utah's Huntsman Cancer Institute, and editor-in-chief of ASCO Daily News. I am delighted to welcome Dr. Jeanny Aragon-Ching, a genitourinary oncologist and the clinical program director of Genitourinary Cancers at the Inova Schar Cancer Institute in Virginia. Today, we will be discussing key posters and oral abstracts that will be featured at the 2024 ASCO Genitourinary Cancer Symposium, which is celebrating 20 years of evolution in GU oncology this year.  You will find our full disclosures in the transcript of this podcast, and disclosures of all guests on the podcast at asco.org/DNpod.  Jeanny, it's great to have you on the podcast today to highlight some key abstracts for our listeners ahead of the GU meeting. Dr. Jeanny Aragon-Ching: Thank you so much, Neeraj. It's an honor to be here. Dr. Neeraj Agarwal: Jeanny, as you know, this year we are celebrating the 20th anniversary of the ASCO GU Cancers Symposium, and judging from this year's abstracts, it's clear that this meeting continues to play a major role in advancing GU cancer research. Dr. Jeanny Aragon-Ching: Indeed, Neeraj. This year's abstracts reflect the important strides we have made in GU cancers. So, let's start with the prostate cancer abstracts. What is your takeaway from Abstract 19 on BRCAAway, which will be presented by Dr. Maha Hussein, and of which you are a co-author? As our listeners know, several PARP inhibitor combinations with second-generation androgen receptor pathway inhibitors, or ARPIs, have recently been approved as first-line treatment for patients with metastatic castrate-resistant prostate cancer, or metastatic CRPC, and the question of sequencing PARP inhibitors and ARPIs instead of combining them has emerged. From that perspective, the results of the BRCAAway trial are very important. Can you tell us a little bit more about this abstract, Neeraj?  Dr. Neeraj Agarwal: I totally agree with you, Jeanny. The BRCAAway study attempts to answer the crucial questions regarding sequencing versus upfront combination of therapies in the mCRPC setting. It is a phase 2 trial of abiraterone versus olaparib versus abiraterone with olaparib in patients with mCRPC harboring homologous recombination repair mutations. Enrolled patients had mCRPC disease and no prior exposure to PARP inhibitors or ARPIs or chemotherapy in the mCRPC setting and had BRCA1 or BRCA2 or ATM mutations. As previously mentioned, these patients were randomized to 3 arms: abiraterone monotherapy at 1000 milligrams once daily, or olaparib monotherapy at 300 milligrams twice daily, or the combination of abiraterone and olaparib. The primary endpoint was progression-free survival per RECIST 1.1 or Prostate Cancer Working Group 3-based criteria or clinical assessment or death, so, whichever occurred first was deemed to be progression.   Secondary endpoints included measurable disease response rates, PSA response rate, and toxicity. This was a relatively small trial with 21 patients in the combination arm, 19 patients in the abiraterone monotherapy arm, and 21 patients in the olaparib monotherapy arm. It should be noted that 26% of patients had received docetaxel chemotherapy in the hormone-sensitive setting, and only 3% of patients had any prior exposure to an ARPI, and these were darolutamide or enzalutamide or in the non-metastatic CRPC setting.  The results are very interesting. The median progression-free survival was 39 months in the combination arm, while it was 8.4 months in the abiraterone arm and 14 months in the olaparib arm. An important finding that I would like to highlight is that crossover was also allowed in the monotherapy arms. Of the 19 patients receiving abiraterone, 8 crossed over to receive olaparib, and of the 21 patients receiving olaparib, 8 crossed over to the abiraterone arm. The median PFS from randomization was 16 months in both groups of patients who received abiraterone followed by olaparib or those who received olaparib followed by abiraterone. This is striking when compared to 39 months in patients who started therapy with the combination therapy of abiraterone with olaparib. Dr. Jeanny Aragon-Ching: Thank you so much for that wonderful summary, Neeraj. So the key message from this abstract is that combining olaparib and abiraterone upfront seems to be associated with improvement in PFS compared to just sequencing those agents. Dr. Neeraj Agarwal: Exactly, Jeanny. I would like to add that these results are even more important given that in real-world practice, only half of the patients with mCRPC receive a second-line treatment. Based on these results, upfront intensification with a combination of an ARPI plus a PARP inhibitor in the first-line mCRPC setting seems to have superior efficacy compared to sequencing of these agents. Dr. Jeanny Aragon-Ching: Thank you so much. Now, moving on to a different setting in prostate cancer, there were a couple of abstracts assessing transperineal biopsy compared to the conventional transrectal biopsy for the detection of prostate cancer. So let's start with Abstract 261. Neeraj, can you tell us a little bit more about this abstract? Dr. Neeraj Agarwal: Sure, Jeanny. So, in Abstract 261 titled "Randomized Trial of Transperineal versus Transrectal Prostate Biopsy to Prevent Infection Complications," Dr. Jim Hugh and colleagues led a multicenter randomized trial comparing these 2 approaches, so, transperineal biopsy without antibiotic prophylaxis with transrectal biopsy with targeted prophylaxis in patients with suspected prostate cancer. The primary outcome was post-biopsy infection. Among the 567 participants included in the intention-to-treat analysis, no infection was reported with the transperineal approach, while 4 were detected with the transrectal approach, with a p-value of 0.059. The rates of other complications, such as urinary retention and significant bleeding, were very low and similar in both groups. The investigators also found that detection of clinically significant cancer was similar between the 2 techniques and concluded that the transperineal approach is more likely to reduce the risk of infection without antibiotic prophylaxis. Dr. Jeanny Aragon-Ching: So the key takeaway from this abstract sounds like office-based transperineal biopsy is well-tolerated and does not compromise cancer detection, along with better antibiotic stewardship and health care cost benefits.  Moving on to Abstract 273, also comparing these two approaches, what would be your key takeaway message, Neeraj?  Dr. Neeraj Agarwal: In this Abstract 273, titled "Difference in High-Risk Prostate Cancer Detection between Transrectal and Transperineal Approaches," Dr. Semko and colleagues found that the transperineal biopsy based on MRI fusion techniques was also characterized by a higher possibility of detecting high-risk prostate cancer and other risk factors as well, such as perineural and lymphovascular invasion or the presence of cribriform pattern, compared to the conventional transrectal method. Dr. Jeanny Aragon-Ching: Thank you, Neeraj. So we can see that the transperineal approach is gaining more importance and could be associated with more benefits compared to the conventional methods.   Let's now switch gears to kidney cancer, Neeraj. Dr. Neeraj Agarwal: Sure, Jeanny. Let's start by highlighting Abstract 361, which discusses patient-reported outcomes of the LITESPARK-005 study. So what can you tell us about this abstract, Jeanny?  Dr. Jeanny Aragon-Ching: Thank you, Neeraj. So as a reminder to our listeners, based on the LITESPARK-005 trial, it was a Phase 3 trial looking at belzutifan, which is an inhibitor of hypoxia inducible factor 2 alpha or I'll just call HIF-2 alpha for short, was very recently approved by the FDA as a second-line treatment option for patients with advanced or metastatic clear cell renal cell carcinoma after prior progression on immune checkpoint and antiangiogenic therapies. The title of Abstract 361 is "Belzutifan versus Everolimus in Patients with Previously Treated Advanced RCC: Patient-Reported Outcomes in the Phase 3 LITESPARK-005 Study," and this will be presented by Dr. Tom Pells at the meeting. At a median follow-up of 25.7 months, the median duration of treatment with belzutifan was 7.6 months, while it was only 3.9 months with everolimus. At the time of data cutoff date for the second interim analysis, 22.6% of patients remained on belzutifan while only 5% remained on everolimus. In the quality of life questionnaires, the time of deterioration to various quality of life scores, as assessed by standardized scales, was significantly longer in patients randomized to the belzutifan arm compared to those in the everolimus arm. Also, patients in the everolimus arm had worse physical functioning scores. Dr. Neeraj Agarwal: Yes, Jeanny. In addition to the improved outcomes associated with belzutifan, patient-reported outcomes indicate better disease-specific symptoms and better quality of life among patients treated with belzutifan compared to everolimus. This is great news for patients with advanced renal cell carcinoma.  Now, Jeanny, can you please tell us about the two abstracts that reported longer follow-up of CheckMate 9ER and CheckMate 214 trials in untreated patients with advanced or metastatic renal cell carcinoma? Dr. Jeanny Aragon-Ching: Yes, Neeraj. So you are referring to Abstracts 362 and 363. Let's start with Abstract 362. This abstract reports the results after a median follow-up of 55 months in the CheckMate 9ER trial, comparing the combination of nivolumab and cabozantinib to sunitinib in patients with advanced RCC without any prior treatment, so first-line therapy. The primary endpoint was PFS per RECIST 1.1 as assessed by an independent central review. So there were key secondary outcomes including overall survival (OS), objective response rates, and safety. Consistent with prior analysis at a median follow-up time of 18.1 and 44 months, the combination of nivolumab and cabozantinib at a median follow up of 55.6 months continues to show a significant reduction in the risk of progression or death by 42% and in the risk of death by 23% compared to sunitinib.  Dr. Neeraj Agarwal: And Jeanny, what can you tell us about the efficacy results of this combination by IMDC risk categories? Dr. Jeanny Aragon-Ching: Similar to prior results in patients with intermediate to poor risk IMDC risk category, the combination treatment maintained significant efficacy and reduced the risk of progression or death by 44% and the risk of death by 27%. To put it simply, the update now shows a 15-month improvement in overall survival with the cabozantinib-nivolumab combination compared to sunitinib, which is amazing. Also, in patients with favorable IMDC risk group, which represented truly a small number of patients in the trial, there was a strong trend for improvement of outcomes as well. I would like to point out that no new safety concerns were identified. Dr. Neeraj Agarwal: So, it looks like the key message from this abstract is that with longer follow-up, the combination of nivolumab and cabozantinib maintains a meaningful long-term efficacy benefit over sunitinib, supporting its use for newly diagnosed patients with advanced or metastatic renal cell carcinoma.   Let's move on to Abstract 363, which compares nivolumab with ipilimumab to sunitinib in first-line advanced renal cell carcinoma. What would you like to tell us about this abstract, Jeanny? Dr. Jeanny Aragon-Ching: Yes, Neeraj. The title of this abstract is "Nivolumab plus Ipilimumab versus Sunitinib for the First-Line Treatment of Advanced RCC: Long-Term Follow-Up Data from the Phase 3 CheckMate 214 Trial." In this abstract, Dr. Tannir and colleagues report outcomes with the longest median follow-up in first-line advanced RCC setting for any clinical trial. So the median follow-up now is about 18 months. The primary endpoints were OS, PFS, and objective response rates, as assessed by an independent review according to RECIST 1.1 criteria in the intermediate to poor risk IMDC risk group, which is the intent-to-treat (ITT) analysis, while secondary outcomes included the same outcomes in the ITT population of patients. Although the progression-free survival was similar in both arms, the combination of nivolumab-ipilimumab reduced the risk of death by 28% compared to sunitinib in the ITT population of patients. When stratifying the results by IMDC risk groups, the combination arm of nivolumab-ipilimumab showed significant improvement in the intermediate to poor risk group, but there was no difference in the favorable risk group. But in the study, no new safety signals were identified. Dr. Neeraj Agarwal: Thank you, Jeanny, for such a comprehensive description of the results of these two studies. I'd like to add that the median overall survival of patients with metastatic renal cell carcinoma in the ITT population in the CheckMate 214 trial has now reached 53 months, which would have been unimaginable just a decade ago. This is wonderful news for our patients. So the key takeaway from these two abstracts would be that immune checkpoint inhibitor-based combinations remain the backbone of first-line advanced renal cell carcinoma treatment.  Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. This is wonderful news for all of our patients, especially for those who are being treated for first-line therapy.  Now, let's move on to the bladder cancer abstracts. We have two exciting abstracts from the UNITE database. What are your insights on Abstract 537, titled "Outcomes in Patients with Advanced Urethral Carcinoma Treated with Enfortumab Vedotin After Switch-Maintenance of Avelumab in the UNITE Study"? Dr. Neeraj Agarwal: As our listeners know, enfortumab vedotin is an antibody-drug conjugate that binds to a protein called Nectin 4 expressed on bladder cancer cells. In this abstract, Dr. Amanda Nizam and colleagues describe outcomes in 49 patients receiving third-line enfortumab vedotin after prior progression on platinum-based therapy and maintenance avelumab. At a median follow-up of 8.5 months, the median progression-free survival was 7 months and the median overall survival was 13.3 months with enfortumab vedotin in this treatment-refractory setting, the objective response rates were 54%. The message of this study is that enfortumab vedotin is an effective salvage therapy regimen for those patients who have already progressed on earlier lines of therapies, including platinum-based and immunotherapy regimens. Dr. Jeanny Aragon-Ching: Thank you, Neeraj, for that comprehensive review.  I want to focus on another patient population in the UNITE database, which is the use of fibroblast growth factor receptor (FGFR) alterations. Can you tell us more about the sequencing now of erdafitinib and enfortumab vedotin in these patients with metastatic urothelial cancer, as discussed in Abstract 616? Dr. Neeraj Agarwal: Sure, Jeanny. As a reminder, erdafitinib is a fibroblast growth factor receptor kinase inhibitor approved for patients with locally advanced or metastatic urothelial carcinoma harboring FGFR2 or FGFR3 alterations after progression on platinum-based chemotherapy. However, the optimal sequencing of therapies in these patients is unclear, especially with enfortumab vedotin being approved in the salvage therapy setting and now in the frontline therapy setting.  So in this retrospective study, all patients with metastatic urothelial carcinoma had FGFR2 or FGFR3 alterations. Dr. Cindy Jiang and colleagues report outcomes in 24 patients receiving enfortumab vedotin after erdafitinib, 15 patients receiving erdafitinib after enfortumab vedotin, and 55 patients receiving enfortumab vedotin only. This is a multicenter national study. Interestingly, patients receiving both agents had a longer overall survival in a multivariate analysis, regardless of the treatment sequencing, than patients receiving enfortumab vedotin alone or only with a hazard ratio of 0.52. The objective response rate of enfortumab vedotin in the enfortumab vedotin monotherapy arm was 49%. When these agents were sequenced, the objective response with enfortumab vedotin was 32% after erdafitinib and 67% when used before erdafitinib. Dr. Jeanny Aragon-Ching: Thank you so much, Neeraj. I think these are important real-world data results, but I would like to point out that larger and prospective studies are still needed to confirm these findings, especially regarding the outcome of erdafitinib after enfortumab vedotin, particularly when the latter is used in the first-line setting. Dr. Neeraj Agarwal: I totally agree, Jeanny. Now, let's discuss some abstracts related to disparities in the management of patients with genitourinary cancers.  Dr. Jeanny Aragon-Ching: Sure, actually, I would like to discuss 2 abstracts related to disparities in patients with prostate cancer. So the first one, Abstract 265, titled "Patient-Provider Rurality and Outcomes in Older Men with Prostate Cancer." In this study, Dr. Stabellini, Dr. Guha and the team used a SEER Medicare-linked database that included more than 75,000 patients with prostate cancer. The primary outcome was all-cause mortality, with secondary outcomes included prostate cancer-specific mortality. The investigators showed that the all-cause mortality risk was 44% higher in patients with prostate cancer from rural areas who had a provider from a non-metropolitan area compared to those who were in a metropolitan area and had a provider also from a metropolitan area. Dr. Neeraj Agarwal: Those are very important data and highlight the healthcare disparities among the rural population with prostate cancer that still exist.  So what is your key takeaway from Abstract 267, titled "Rural-Urban Disparities in Prostate Cancer Survival," which is a population-based study? Dr. Jeanny Aragon-Ching: Of course. This abstract discusses, actually, a very similar issue regarding access to healthcare among rural versus urban patients. In this study, Dr. Hu and Hashibe and colleagues and team at the Huntsman Cancer Institute assessed all-cause death and prostate cancer-related death risk in a retrospective study in which patients with prostate cancer based on rural versus urban residencies looked at 18,000 patients diagnosed with prostate cancer between 2004 and 2017. 15% lived in rural counties. Similar to the prior abstract we talked about, patients living in rural areas had about a 19% higher risk of all-cause mortality and a 21% higher risk of prostate cancer-specific mortality in comparison to patients living in urban areas. Dr. Neeraj Agarwal: So Jeanny, we can say that both of these abstracts, led by different groups of investigators, highlight that patients with prostate cancer living in rural areas have inferior survival outcomes compared to those living in urban areas, and it is time to focus on the disparities experienced by the rural population with prostate cancer.  Dr. Jeanny Aragon-Ching: Yeah, absolutely Neeraj. I concur with your thoughts.  So, any final thoughts before we wrap up the podcast today? Dr. Neeraj Agarwal: Yes, before concluding, Jeanny, I want to express my gratitude for your participation and the valuable insights you have shared today. Your contributions are always appreciated, and I sincerely thank you for taking the time to join us today.   As we bring this podcast to a close, I would like to highlight the significant advances happening in the treatment of patients with genitourinary cancers during our upcoming 2024 ASCO GU meeting. Many studies featuring practice-impacting data will be presented by investigators from around the globe. I encourage our listeners to not only participate at this event to celebrate these achievements, but to also play a role in disseminating these cutting-edge findings to practitioners worldwide. By doing so, we can collectively maximize the benefit for patients around the world.  And thank you to our listeners for joining us today.

Today, we'll explore how we interpret and integrate recently reported clinical research into practice. In a previous episode, we explored the clinical scenario of localized prostate cancer progressing to metastatic hormone-sensitive disease. Today, our focus will be on de novo metastatic prostate cancer. My name is Kriti Mittal and I am the Medical Director of GU Oncology at the University of Massachusetts. I am delighted to co-host today's discussion with my colleague, Dr. Jorge Garcia.  Dr. Garcia is a Professor of Medicine and Urology at Case Western Reserve University School of Medicine. He is also the George and Edith Richmond Distinguished Scientist Chair and the current Chair of the Solid Tumor Oncology Division at University Hospitals Seidman Cancer Center.  Here are the details of the patient case we will be exploring: The patient also notes intermittent difficulty in emptying his bladder with poor stream for the last six months. A CT scan of the abdomen and pelvis demonstrates enlarged prostate gland with bladder distension, pathologically enlarged internal and external iliac lymph nodes, and multiple osteolytic lesions in the lumbar sacral, spine, and pelvic bones. A CT chest also reveals supraclavicular lymphadenopathy and sclerotic foci in three ribs. So this patient meets the criteria for high-volume disease and also has axial and appendicular lesions.  The patient was admitted for further evaluation. A bone scan confirmed uptake in multiple areas identified on the CT, and a PSA was found to be greater than 1500. Biopsy of a pelvic lymph node confirmed the diagnosis of prostate cancer. This patient is somewhat different from the first case we presented in terms of timing of presentation; this patient presents with de novo metastatic high-volume disease, in contrast to the first patient who then became metastatic after undergoing treatment for high-risk localized disease.  Would you consider these two cases different for the purposes of dosing docetaxel therapy when you offer upfront triplet therapy combinations?  Dr. Jorge Garcia: That's a great question. I actually do not. The natural history of someone with localized disease receiving local definitive therapy progressing over time is different than someone walking in with de novo metastatic disease. But now, with the challenges that we have seen with prostate cancer screening, maybe even COVID, to be honest with you, in North America, with the late care and access to testing, we do see quite a bit of patients actually walking in the office with de novo metastatic disease. So, to me, what defines the need for this patient to get chemotherapy is the volume of his disease, the symptoms of his disease – to be honest with you – and the fact that, number one, he is clinically impaired. He has symptomatic disease, and he does have a fair amount of disease, even though he may not have visceral metastasis. Then his diseases give him significant pain.  Oral agents are very good for pain control. I'm not disputing the fact that that is something that actually these agents can do. But I also believe I'm senior enough and old enough to remember that chemotherapy, when it works, can actually really alleviate pain quite drastically. So for me, I think that the way that I would probably counsel this patient is to say, "Listen, we can give you ADT plus an oral agent, but I really believe your symptomatic progression really talks about the importance of rapid control of your disease.” And based upon the charted data from the United States, and equally important, PEACE-1, which is the French version of ADT, followed by abiraterone, if you will, and certainly ARASENS is the standard of care for me for a patient like this will be triple therapy with ADT and docetaxel.  What I think is important for us to remember is that, in ARASENS, it was triple therapy together. I am worried sometimes about the fatigue that patients can have during the first six cycles of docetaxel. So oftentimes, I tell them if they're super fit, I may just do triple therapy up front, but if they I think they're going to struggle, what I tell them is, "Hey, we're going to put you on ADT chemotherapy. Right after you're about to complete chemo, we'll actually add on the darolutamide." So I do it in a sequence, and I think that's part of the data; we just still don't know if it should be given three at front or ADT chemo, followed by immediately, followed by an ARI. So I love to hear if that's how you practice or you perhaps have a different thought process. Dr. Kriti Mittal: So I usually start the process of prior authorization for darolutamide the day I meet them for the first time. I think getting access to giving docetaxel at the infusion center is usually much faster than the few weeks it takes for the prior authorization team to get copay assistance for darolutamide. So, in general, most of my patients start that darolutamide either with cycle two or, depending on their frailty, I do tend to start a few cycles in like you suggested. I've had a few patients that I've used the layered-in approach, completing six cycles of chemotherapy first and then layering in with darolutamide.  I think conceptually the role of intensifying treatment with an androgen receptor inhibitor is not just to get a response. We know ADT will get us a PSA response. I think the role of an androgen receptor inhibitor is to prevent the development of resistance. So, delaying the development of resistance will be pertinent to whether we started with cycle one, cycle six, or after. So, we really have to make decisions looking at the patient in front of us, looking at their ECOG performance status, their comorbidities, and frailty, and we cannot use a one-size-fits-all approach.  Dr. Jorge Garcia: Yeah, I like that and I concur with that. Thank you for that discussion. I think that you may recall some of our discussions in different venues. When I counsel patients, I tell the patients that really the goal of their care is on the concept of the three Ps, P as in Peter. The first P is we want to prolong your life. That's the hallmark of this regimen, the hallmark of the data that we have. That's the goal, the primary goal of these three indications is survival improvement. So we want to prolong your life so you don't die anytime soon from prostate cancer.  The second P, as in Peter, is to prevent, and the question is preventing what? We want to prevent your cancer from growing, from growing clinically, from growing radiographically, and from growing serologically, which is PSA and blood work. Now, you and I know and the audience probably realize that the natural history of prostate cancer is such that traditionally your PSA will rise first. There is a lead time bias between the rise and the scan changes and another gap in time between scans and symptoms. So it's often not the case when we see symptomatic disease preceding scans or PSAs, but sometimes in this case, it's at the same time. So that is the number one. And as you indicated, it's prevention of resistance as well, which obviously we can delay rPFS, which is a composite endpoint of radiographic progression, symptomatic progression, and death of any cause.  But the third P is I called it the P and M, which is protecting and maintaining, and that is we want to protect your quality of life while we treat you. And we want to maintain your quality of life while we treat you. So to me, it's critically important that in addition of aiming for an efficacy endpoint, we don't lose sight of the importance of quality of life and the protection of that patient in front of us. Because, undoubtedly, where you get chemo or where you get an oral agent, anything that we offer our patients has the potential of causing harm. And I think it is a balance between that benefit and side effect profile that is so critically important for us to elucidate and review with the patient.  And as you know, with the charted data, Dr. Alicia Morgans now at Dana-Farber, published a very elegant paper in JCO looking at the impact of docetaxel-based chemotherapy as part of the charted data in the North American trial and into quality of life. And we clearly define that your quality of life may go down a bit in the first few months of therapy, predictably because you're getting chemotherapy. But at the end of the six months, nine months, and certainly at the end of a year mark, the quality of life data for those who receive ADT and chemotherapy was far better than those who actually got ADT alone.  Now, if you look at the quality of data for RSNs, a similar pattern will appear that although chemotherapy is tied to misconceptions of significant toxicity, in our hands, in good hands, and I think our community of oncology in North America are pretty familiar with the side effects and how to manage and minimize side effects on chemotherapy, I think it still requires a balance and a thoughtful discussion to make sure that we're not moving forward chasing a PSA reduction at the expense of the quality of life of the patient. So I think orchestrating that together with the patient as a team is critically important as well.  Dr. Kriti Mittal: Thank you, Dr. Garcia. Moving on to the next concept we'd like to discuss in today's podcast the role of PARP inhibitors. Case Two was treated with androgen deprivation docetaxel and darolutamide. Consistent with current guidelines, the patient was also referred to germline testing and was found to be BRCA 2-positive. The patient's disease remained stable for 24 months, at which time he demonstrated disease progression, radiographically and clinically, and his disease was termed castration-resistant. There has been a lot published in the last few years regarding the role of PARP inhibitors in metastatic castration-resistant prostate cancer, or mCRPC.  The PROfound trial led to the approval of olaparib in patients with deleterious mutations in HRR genes for those who had been treated previously with AR-directed therapy. The TRITON2 trial led to the approval of rucaparib in the same month for mCRPC patients with BRCA mutation for those patients who had previously been treated with AR inhibitors and taxine-based chemotherapy. More recently, we saw data from the TRITON3 trial exploring the role of rucaparib versus physicians' choice of docetaxel versus AR-inhibitor therapy in the mCRPC space for patients harboring BRCA 1, BRCA 2, or ATM mutation. Based on these data, it would be very tempting to offer a PARP inhibitor to the patient in case two. While regulatory authorities are still reviewing those data for approval, how would you consider treating this newly castrate-resistant patient in the frontline setting? Would you consider a PARP inhibitor in the frontline treatment of mCRPC in this patient with a BRCA 2 mutation? Dr. Jorge Garcia: So that's a loaded question, to be honest with you. We have compelling data, but controversial data, as you know as well. So I think that since we have a genomic profile on this patient and we know he had high volume disease, then the first thought to me is not a genetic or a genomic question or a sequence. It's actually a clinical question, to be honest with you. And that is: How are you progressing? Because I think that if you're progressing serologically, you and I may think of that patient differently. If you're progressing radiographically with alone plus minus PSA production but no symptoms, you may also tilt your scale into this life-prolonging agents in a different way. Whereas if you have true symptomatic disease, knowing what you know, prior therapy, CrPC with a BRCA 2 alteration, then you may actually go for something different.   So if it's a rising PSA, if it is radiographic, but the patient is stable clinically, is not basically compromised by symptomatic disease, I do feel that a PARP inhibitor as a single agent would be a very reasonable choice. In this case, you can use, obviously, rucaparib. You can use olaparib. I don't have a vested interest in either/or. I think either/or is fine. The subtleties and side effects, as you know, the olaparib data was probably the data that you and I probably are more accustomed to, used to the most just by virtue of how the agents got registered in the United States. But either/or, I think a PARP inhibitor would be a reasonable approach.   I think the question perhaps, and I pitch that back to you, is what are you looking for with a PARP inhibitor? Because, as you know, all DNA repair deficiencies are not biologically the same. They do not respond the same way to PARP inhibitors. And even BRCA 2, where we think it's monoallelic or biallelic, may have subtleties in how those patients respond to PARP therapy. But the answer is yes, obviously, you have a biomarker, the patient has it, you can use it. I think the question is, how are you going to follow the patient? And what is going to be the endpoint that you're going to pay attention to in this case to find that the patient has a benefit or not granted, that could be PSA driven, but I think that perhaps I'm pushing you to think beyond PSA.  Dr. Kriti Mittal: I agree, Dr. Garcia. I think we need to think about the patient as a whole. PSA-based changes in treatment are not generally part of our practice. I think evaluating the patient for symptoms and also thinking about the sites of progression, sites of disease they've had in the past, preventing development of cord compression, because some of these patients progress very rapidly and present with cord compression at the time of progression. Those are the things we are trying to predict and prevent. I think in a patient with BRCA 2 mutation, in this situation, I would feel compelled to offer rucaparib, given that even in the intention-to-treat analysis, the hazard ratio was 0.6 in terms of median progression-free survival. I think what was quite impressive was the subset analysis comparing rucaparib versus docetaxel. And that was something surprising. And I think we'll have to wait for long-term outcomes. But certainly, for a BRACA 2-mutated patient, this could be a reasonable consideration provided the drug is available and approved.  Dr. Jorge Garcia: As you know, the three most common DNA repair deficiencies that we see are BRCA1, BRCA2, and ATM. BRCA2 is probably the one that we see the most. But we also recognize that with the limited data we have for ATMs, that patients with an ATM abnormality do not tend to benefit the most. And then yet we have also another series of DNA repair deficiencies, deficiencies, PALB2, CHEK2, CDK12 and so forth. And yet we have some exquisite responses to some of those patients.   So I can tell you that I have a patient of mine who had an ATM mutation, a germline ATM mutation, and I predicted that initially that the likelihood of benefit to a PARP inhibitor would be low. He was placed on a PARP inhibitor and surprise, surprise, he was on a PARP inhibitor for almost a couple of years. What I want to convey to the audience is that if you have the appropriate biomarker, you certainly should consider a PARP inhibitor in this scenario.   I think the bigger question is also understanding that not every DNA repair would benefit the same way. So being very thoughtful and very structured as to how you're going to manage the patient, it cannot be PSA only, the patient has to be followed radiographically and clinically because I would argue that if this patient had just a serologic progression, I would put the patient on a PARP inhibitor and the PSA kinetics change north, but slowly, what is the urgency of you switching the patient to something else?   And also the misconception that if you look at PROfound, that olaparib for that matter has to always be given after docetaxel. That's not the case. The makeup of PROfound is different than this patient, obviously, because this patient got triple therapy upfront, whereas most patients on the PROfound were CRPC who receive chemotherapy in the CRPC space. But yet undoubtedly, I think that your case illustrates the importance of next-generation sequencing and the importance of understanding the access to two oral PARP inhibitors that are super solid.  I think that perhaps the bigger question is going to be should you do a PARP inhibitor alone or should we use a combination of a PARP inhibitor plus an oral agent, such as in this case, maybe abiraterone acetate plus olaparib. Or maybe even thinking of TALAPRO, maybe enza plus a PARP inhibitor. So I don't know where you sit on those thoughts, Doctor-. Dr. Kriti Mittal: I change toxicity considerations, temper my enthusiasm for offering PARP inhibitors in combination with AR inhibitors or abiraterone at this time. I think I would certainly consider monotherapy with rucaparib for a patient in this situation. I am not entirely convinced that putting a patient through dual treatment in the mCRPC setting in the frontline, I don't think we are there yet. Dr. Jorge Garcia: There are two very important trials that are looking at the combination of an adrenal biosynthesis inhibitor plus olaparib in this context, and one is PROpel and the other one is MAGNITUDE. And both trials have very different results in many ways because they look at patients with a biomarker, meaning DNA repair, and patients without the biomarker. And I think the bigger question is, should this patient who was an abiraterone– Let's say this patient hypothetically was on a PEACE-1-like style. So the patient got ADT or triple therapy but was an abiraterone or an adrenal biosynthesis inhibitor instead of chemotherapy. And the patient was progressing slowly on abiraterone, you knew that the patient had a DNA repair deficiency. How comfortable with the PROpel and MAGNITUDE data would you and I feel to add on or layer, if you allow me to express it like that, a PARP inhibitor into this regime? Dr. Kriti Mittal: My personal interpretation of the currently available data is that at this point, combination therapy is not something I would use in my clinical practice. I think there are two camps in the GU oncology community of how people interpret the PROpel, MAGNITUDE, TRITON, and TALAPRO data in full. I think each of these trials had very different patient populations. I think in a biomarker unselected population, I would certainly not advocate for combination therapy. But even in the biomarker-selected population, I think how the biomarkers were tested and how the populations were defined may not always match what we are doing in clinical practice. And so I would, at this time, advocate for monotherapy over combination therapy. Dr. Jorge Garcia: I'm sure the audience will have probably read or heard about PROpel and MAGNITUDE and the data in patients without a biomarker positivity disease. So I'd love to hear your thoughts as to if you had no biomarker. By that I mean if you had a patient with CRPC, with metastatic CRPC without a DNA repair deficiency, would you consider using an adrenal biosynthesis inhibitor and a PARP inhibitor together based upon the potential synergistic of additive benefits and some of the data to suggest that you can delay rPFS when you combine therapy, but in the absence of biomarker positivity. Dr. Kriti Mittal: In the absence of biomarker positivity, I think the preclinical data are stronger than the clinical results we are seeing in trials. So while I think we should continue researching further into this because there certainly is preclinical rationale, looking at the clinical outcomes from these several trials, I would not offer PARP inhibitor to an unselected patient. Dr. Jorge Garcia: Great. Dr. Kriti Mittal: Moving on to second-line treatment for castration-resistant prostate cancer. I think talking of access issues and talking about the current treatment paradigms in the United States, there is still not widespread availability of lutetium. The listeners would love to hear your thoughts, Dr. Garcia, on practical management tips, safety issues, and the multidisciplinary nature of the management of lutetium therapy.  Dr. Kriti Mittal: So I think the challenges with lutetium are multiple. Number one is the correct identification of the patient, the ideal patient for lutetium. Secondly is who manages the patient and as you indicated, the importance of a team approach in that. Thirdly is how do we follow that patient during therapy? So it's beyond the technical aspects of who infuses the patient. Fourthly is what are the true goals of lutetium for that patient population and the side effects that those patients may embark on that some people may not be fully aware of and creates complexity. And lastly, perhaps, is how the movement, how we develop lutetium in CRPC and how we're going to move lutetium or have started to move lutetium and alike, meaning radiopharmaceuticals, radioligand-based therapies outside lutetium opinion and others as you know, earlier into the natural history of prostate cancer, maybe even in the locally advanced disease in combination with radiation or for patients with N1 positive disease. So it's a lot of movement in that space. I think that this is just the beginning of radiopharmaceutical entering diagnostics. But let me just address this succinctly, if I may. Number one, you do need a PET PSMA in order for you to select the patient because we're talking about a potential biomarker. But this is what I call an imaging biomarker. If you see it, you treat it.  So the standard of care right now for lutetium is very simple: you need to have men with metastatic castration-resistant prostate cancer. Two, you need to have failed a prior oral agent, in this case, a novel hormonal agent, independent of which agent you have seen, independent of the timing when you have seen an oral agent at the front, the middle, the end. And lastly, you have to have progress through chemotherapy. Yet again, it depends on when you see chemo.  So if you have someone who has high volume metastatic disease from the beginning, de novo disease, and you got ADT, daro, and docetaxel, and the patient progresses, that patient can go on. If that patient has a positive PSMA PET, that patient can go on to get lutetium. Similarly, if you have someone who got ADT alone in the adjuvant space for radiation therapy, progress, got an oral agent, progress, got a PARP or not, or got docetaxel, that patient could also be a candidate for lutetium. It's dependent on how you run the patient through therapy.  Secondly is who gives lutetium? So I do believe, and I may be biased, I certainly believe in the importance of a team approach with radiation oncology and nuclear medicine. But the reality of it is, I believe these patients are so advanced in their stage of their disease, then the idea of quarterback, in my personal opinion, resides in medical oncology. And I think the bigger question is going to be if nuclear medicine at your given institution is going to be delivering lutetium, or is it going to be radiation oncology? And I think, as you know, in places in America, it's RadOnC, in other places is NucMed, in our institution right now it is NucMed. Having said that, I do predict that for those places where nuclear medicine is heavily involved in delivering lutetium or partnering with MedOnc to deliver lutetium, radiation oncology in the future will have a bigger role as well because we are moving lutetium earlier in settings where radiation oncology is commonly used, such as high-risk prostate cancer patients, or even in the salvage setting, or even in patients with metastatic disease, where we want to combine radiation and lutetium, which are part of clinical trials as we think through for the future. But either/or, I think the quarterback should be really MedOnc in this case.  Thirdly is how do we do it? So clearly, at least in my practice, and I think it's probably standard across the United States, MedOnc will see the patient, determine viability and feasibility of therapy, determine who's the ideal candidate, discusses the pros and the cons, and then works along with RadOnc or NucMed to start the process. As you know, it is once every six weeks. So here in my practice, we will see the patient every time before treatment. Sometimes we see them the day off, sometimes we see them a few days before. Patients will get blood work. Specifically, we're interested in seeing everything CMPs, but certainly blood counts, red cell counts, platelets, and white cell counts, just to make sure that patients do not start with impaired bone marrow that can increase the risk for myelosuppression and therefore significant challenges with side effects, hematologic side effects, specifically. And we do that.   Sometimes we see them, sometimes our nurse practitioners would do so. And then the patient will basically follow through and complete up to six cycles of treatments. Six times six, that's actually 36 weeks or so. That's a long time on therapy for those who can get six cycles. I think the question becomes how do you follow those patients? And if we pay attention to the VISION data, as you know, those patients were actually followed serially quite closely on trial every eight weeks for the first 24 weeks, and then they stretch the scans out. But the scans that we're using in the trial are conventional imaging.  And I think the bigger question that you and I will have is if we get a PET PSMA to use to make that decision to get on lutetium PSMA, should I go back and use a CT or so to stage the patient? I think we're moving more toward PET follow-up, but we also don't know fully the impact of lutetium PSMA on PSMA metabolically during treatment. I think that we all recognize anecdotally and at least with some of the emerging data and we have the SUV may change, that PSA reductions also appear to be important as to define who is likely to benefit or not. But those are questions that remain to be seen, to be honest with you. We follow the patients serologically, clinically, and radiographically. And at least in my group, we tend to do PSMA PETs in between therapy to ascertain the impact of therapy in radiographic and also metabolic changes. And lastly is how we manage side effects. So I think that I'm pretty OCD about these patients because I have seen in my practice patients having outstanding responses to therapy but unfortunately become transfusion dependent, either transiently or permanently, just by virtue of side effects. And I think the importance of understanding the most common side effects of lutetium, in this case fatigue, myelosuppression, xerostomia, are really, really important. And that is the importance of having a multi-team effort approach so everybody is fully aware of the baseline characteristics of that patient or how the patient is enduring therapy and how the therapy is impacting the quality of life and impacting bone marrow production for those patients.  I think I remind the audience that the vast majority of our patients do have bone metastases. In fact, in the VISION trial it was around what, over 85, 90% of patients are so with bone metastases. So their marrow has already been impacted not only by disease but equally importantly by the prior chemotherapy that they may have seen. And some of the patients that we have in the first bubble effect is they have seen probably docetaxel, some may even have seen dual therapy with cabazitaxel as a second-line chemotherapy. So I think the understanding as to how you manage the side effects is critically important for our patients as well.  Dr. Kriti Mittal: Those are very relevant, practical life issues.

Drs. Pedro Barata and Naomi Haas discuss the emergence of clinical trials investigating triplet combinations in advanced renal cell carcinoma, factors that influence treatment decisions, strategies to personalize therapies in the frontline setting, including response-adaptive treatment strategies, and the use of biomarkers such as gene expression analysis to guide initial therapy. TRANSCRIPT Dr. Pedro Barata: Hello, I'm Dr. Pedro Barata. I'm your guest host of the ASCO Daily News Podcast today. I'm an associate professor of medicine and also a GU medical oncologist at University Hospital Seidman Cancer Center, Case Western University in Cleveland, Ohio. I'm also an associate editor for the ASCO Educational Book. Today I'm really delighted to welcome Dr. Naomi Haas, the director of the Prostate and Kidney Cancer Program at the Abramson Cancer Center and professor of medicine at the University of Pennsylvania.  Welcome, Dr. Haas. Dr. Naomi Haas: Thank you, Dr. Barata. It's a pleasure to be interviewed. Dr. Pedro Barata: Thank you. As you know, we've seen significant strides in the frontline treatment for patients with advanced clear cell renal cell carcinoma (RCC), and there are multiple doublet regimens that are now the standard of care for those patients. The goal for us to chat today is to discuss the emergence of clinical trials that are really investigating triple combinations and the factors that influence treatment decisions around triplet combinations for patients with advanced renal cell carcinoma. I want to congratulate you for the great work that you did in a recently published article in the 2023 ASCO Educational Book. So thank you for your contributions. And just before we get started, I just want to highlight that our full disclosures are available in the transcript of this episode. So, Dr. Haas, again, it's great to have you. Thank you for taking the time. Let me get started. So, we know that there are multiple standard of care doublet regimens, all of them immunotherapy-based combos, and they usually include 1 checkpoint inhibitor or 2, such as ipilimumab plus nivolumab or a combination of an immune checkpoint inhibitor with a VEGF TKI. And we have a number of examples like that. Can you tell us about the trials that have emerged exploring triplet therapies in the first-line setting for patients with advanced RCC? Dr. Naomi Haas: Sure, and I'm going to focus just on triplet therapies that are just about ready to go. But as you know, Pedro, there are probably many different combinations that we'll see in the future. Some of the combinations that have already been conducted as clinical trials include combinations of VEGF receptor tyrosine kinase inhibitors along with immune checkpoint inhibitors. I'll highlight one which was batiraxcept plus cabozantinib and nivolumab, and it's a combination of VEGF inhibitor, immune checkpoint inhibitor, and also an AXL inhibitor. So, most of these capitalize on other vulnerabilities with renal cell carcinoma.  So, as you said, they build on the tyrosine kinase inhibitor pathway or on the immune checkpoint inhibitor pathway. Some of them are combining drugs such as CDK inhibitors. There was axitinib plus nivolumab plus palbociclib trial that is getting ready to launch. Others are combining the use of belzutifan, which is a HIF inhibitor in combination with VEGF inhibitor and immune checkpoint inhibitor. There are a couple of those that are ongoing, one of them looking at combinations with lenvatinib. And I think there are also trials getting ready to launch that are using it in combination with cabozantinib and nivolumab.  Additionally, another very interesting direction is trying to affect the gut microbiome. And there was a clinical trial presented by Dr. Monty Pal at the gut microbiome session at ASCO, which combined CBM-588, which is a probiotic, in combination with cabozantinib and nivolumab. And that showed an improvement in progression-free survival compared to the combination of cabozantinib and nivolumab alone. And previously there was work published using CBM-588 in combination with ipilimumab and nivolumab. So that's an area of high interest to patients. But most of these combinations capitalize on either vulnerabilities, signs of resistance in pathways or in adding other pathways that have previously been unaddressed in renal cell carcinoma, and are combined with pathways that we know are effective. Dr. Pedro Barata: Wow, that's a fantastic overview of some of the approaches being considered in the frontline, so thank you for that. And actually to your point, some of them we've seen some data, others more later stages of development. So with that in mind, we also know that we have on one side of the story we have how much of these combos of triplets can actually be effective and help patients. From the other perspective is about tolerability, treatment options, and patient health. They're both very important considerations.  Can you tell us a little bit about the safety profile of these triplet combos? I know we're talking about many different things. The microbiome triplet has a different safety profile than perhaps a combination with a TKI and different checkpoints, for instance. Can you tell us a little bit about what we expect from the safety profile when we start to combine these therapies in the upfront setting?  Dr. Naomi Haas: Sure. I think 2 of the very tolerable triplet regimens have been the combination of the CBM-588 in combination with ipilimumab and nivolumab. Really in those combinations, the authors at least have demonstrated that there has not been a great difference between the two study arms of either the doublet or the doublet in combination with the CBM-588 trial. And that's based on basically changing the bacterial flora of the gut. The Avera trial, which was using the AXL inhibitor in combination with cabozantinib and nivolumab, also seems to have a very tolerable safety profile. Now, this trial was not compared to sort of a standard of care arm, so it's a little bit difficult. A standard of care arm that I would have considered for this clinical trial would have been to use either cabozantinib alone or cabozantinib with nivolumab. Instead, this was more of a dose-finding protocol. So, more work needs to be done with that, but the side effects of that combination additive to what we already know seem to be just infusion reactions from the AXL inhibitor.  The trial that got the most attention so far has been COSMIC-313, which was combining cabozantinib with ipilimumab and nivolumab upfront. And of course, the concern with this triplet combination was that there was more hepatotoxicity seen and it was difficult to know whether the hepatotoxicity was from the combinations of the immune checkpoint inhibitors or the use of the cabozantinib. And although the trial showed an improvement in progression-free survival, it did not show as many complete responses as the comparator arm. And the other concern was that there was quite a bit of dropout due to toxicity. And of course, we don't have the overall survival endpoint for that trial yet. Dr. Pedro Barata: Great, thank you for that. I agree completely. We've seen many different safety profiles with these different triplets.  Let me touch base on a slightly different topic, and that has to do with what kind of strategies can we think to personalize treatment for clear cell RCC in the frontline. And this is not necessarily applicable only to triplet therapy. There are also some efforts with doublets, but the goal is, I would argue, is response adaptive treatment strategies or even the use of upfront biomarkers such as gene expression analysis, for example, to help us guide initial therapy. Can you give us an idea what your thoughts are about what is coming? What do you think the future will look like in terms of developing this like a biomarker-based approach? What kind of factors or markers we can use to select who gets what in the frontline setting? Dr. Naomi Haas: Sure. So, I'll just highlight ahead of that that one important biomarker that we're already using is the IMDC criteria, which I think if that algorithm had not been developed, we would be struggling a lot in renal cancer and that's, of course, the algorithm that uses the thing such as performance status, hemoglobin, calcium, and time for the development of metastatic disease as well as the neutrophil count and the platelet count. And that has helped us divide categories of patients with clear cell renal cell carcinoma into poor risk, intermediate risk, or favorable risk categories. And that was recently validated in the immune therapy combinations that were previously been validated just in VEGF inhibitor therapies.  But the other useful, let's start with clinical tools that I think are going to be very important are the health-related quality of life tools which primarily measure things such as functional health, as well as toxicity. And one of these is the FKSI-19 score which captures most renal disease-related symptoms, treatments, side effects, and functional well-being. And this has been implemented in some trials and are looked at over time whether the patient's functional status improves. And patients who are responding to therapies generally will improve as far as their overall well-being. Although that can be difficult as a tool because if patients are experiencing toxicity, those signs might not be apparent. But that's one tool that's being used.  Now, people, both patient advocates and patients, have pointed out that it's very hard to use a tool like this in real life to implement in clinic, but there are efforts being carried out to make these tools a little bit easier so that people can use them day-to-day. So, I can see that being implemented more often.  The others have to do with response assessments, and I think it's very important to look at immune-related responses which kind of builds on the resist response, but it uses two dimensions of measurement as opposed to one dimension of measurement. And looking at those, we know now that patients who have what we call a deep response, so something better than a 75% shrinkage or even a 90% shrinkage in a very short period of time tend to be those patients who behave like patients who have complete responses. And both progression-free survival and overall survivals seem to be going in a very encouraging way looking at these tools so you could see that this tool could be implemented in real life with treating a patient and if they have a very deep response quickly, you can feel, the physician or the APP, could be very confident that the patient is going to do well for a long period of time. I think the tools that we're waiting for the most, however, are as you said, the biomarker tools. And this is where we still have a lot of work to do, but one example of this is the transcriptomics which has been conducted in both the atezolizumab-based trials such as the IMmotion trials, and also to some extent with the JAVELIN trials, the avelumab and axitinib trials. And this goes back to looking at the tissues sample and looking at transcriptomics which show mRNA expression as well as some alterations in some of the important genes such as BAP1 and PRBM1.  And those tools have been implemented, especially in the IMmotion trial, there were 7 clusters identified, and two of the clusters are groups of patients whose tumors have transcriptomics that indicate that they would respond well to a VEGF inhibitor. And a couple of them also showed very good responses to immune checkpoint pathways. There were additional pathways which suggested that patients wouldn't be responsive to either of these. And there is a trial called OPTIC that is funded by the Department of Defense (DOD) which is currently applying these transcriptomics, and then assigning patients to get either a VEGF IO therapy combination or a dual immune checkpoint inhibitor combination, based on their transcriptomics.  And I think what everybody would really like to see is, number 1, that these transcriptomics consistently bear out that there isn't irregularity in using these as predictors. So, they do need to be validated. But I think if there was a quick and easy way to do this, to assign patients to therapies based on these profiles, that would perhaps go a long way in predicting what therapy a patient should start with.  Another useful tool is the development of artificial intelligence. And there are a number of companies that are looking at these tools. We're implementing this retrospectively in the ASSURE trial, which was the adjuvant seraphinib synontib or placebo trial, for patients at high risk for RCC. And we're working with a company to identify, using AI, looking at the slides. And I think that if these kinds of techniques, which are already being used in prostate cancer, are something that can be developed, then what I could see in the future is that a patient's slide could be tested very quickly, and that that might also indicate things that perhaps we can't see under the microscope, as far as either a response to treatment or a risk. So, you could use that in the adjuvant setting to predict whether a patient might need adjuvant therapy or not. So I can see those being implemented.  And then the third is looking at cell-free DNA. And there are many different mechanisms that have been tested in other solid tumors, using either circulating tumor DNA or cell-free DNA. Now, the circulating tumor DNA seems to be a little bit more difficult to assess in metastatic kidney cancer because it doesn't have the mutational burden and doesn't seem to have as many mutations and things floating around that can be captured. However, cell-free DNA, which has the capability of measuring DNA methylation profiles, does seem to be showing some promise, and there have been some publications.  So this has also been tested in cancers of all stages and can be measured in both the plasma and in the urine. And that could be another helpful tool that needs to be validated, but that could be used to start a patient on treatment. And if the amounts of cell-free DNA went down with therapy, that could be a good indication, perhaps in advance of imaging, that a patient is doing well with therapy.  So those are some examples that I see potentially being used in the future to help direct therapy, provided that we can make these tools, that we can validate these tools, and secondly, that these tools are relatively inexpensive and that they're nimble, that they could be used right away, that it wouldn't take a long time to get the results back to help guide. Dr. Pedro Barata: For sure. I couldn't agree more. What a masterclass of all the emerging tools that are being investigated in RCC, this is fantastic.  So, I guess maybe one last question before I let you go. We have now a number of doublets, we have perhaps a triplet, if not more. If you were to guess, who do you think will be the ideal population for a triplet therapy? Some, in addition to all the tools you mentioned, maybe sarcomatoid features, etc. that might be part of the AI complement to what you mentioned earlier. But if you were to guess, do you think that 5 years from now, we're going to be offering a triplet therapy, whatever that triple therapy might be, to everybody, to certain populations? What can you tell us to help us predict what might happen in the near future to make us think about a thoughtful, shared decision-making process and try to predict who might be the ideal population for triplet therapy? Dr. Naomi Haas: So, I don't think we're going to use triplet therapy in everybody. And in fact, I hope we don't use triplet therapy in everybody because I have patients who have responded to single-agent nivolumab and remained in a continuous CR many years after they were treated that way. And I have other patients who really progressed very rapidly or relapsed very quickly after doublet therapy combinations. So, I think that what I would see in the future would be using the triplet therapy combinations in the challenging patients, the patients who we know we're not getting as far along with the doublet approach. And that's really our challenge. And I would see that perhaps some of this transcriptomics which indicates that there are subsets of renal cell carcinoma which are not going to respond well to a VEGF inhibitor or to an immune checkpoint inhibitor, that those are areas where there might be other relevant pathways where maybe the signal isn't quite as good with– maybe they have some response, but not an optimal response. And then combining another pathway into that would be a way forward to achieve a complete response in those populations.  I also want to emphasize that it may be that triplet therapy isn't the way to go, but that triplet therapy can be more of an adaptive design where a doublet therapy is started, and then the third drug, a triplet, is added at a later time. And an example of that is PDIGREE, which is the combination of ipilimumab and nivolumab. And then following imaging, patients are assigned, depending on the response, to get either cabozantinib alone, cabozantinib with nivolumab, or to continue on just nivolumab alone. And that might be a better way to address toxicity. But some of these other triplet combinations, one could also see- you could start, for example, with ipilimumab and nivolumab, and if they were having a response but you wanted to heighten the response, maybe adding the CBM-588 as an adaptive response or adding a CDK inhibitor, but sort of staggering the combination so that you spare patients some of the toxicity. So, I think all of those approaches need to be tested. Dr. Pedro Barata: That is fantastic. Dr. Haas, this is an incredible podcast. You did highlight several triplet combinations that are currently under investigation. You highlighted very, very important ongoing clinical trials. You touched base on what the future might bring as far as tools that might help us decide or optimize patient selection. We talked about adaptive designs. So really outstanding work. And also, I think this reflects the fantastic work in the manuscript that you wrote in the 2023 ASCO Educational Book.  So, thank you so much, Dr. Haas, for the incredible work that you have done and you continue to do in the GU field, and for taking the time to share your insights with us today on the ASCO Daily News Podcast.

Drs. Rana McKay and Jonathan Rosenberg highlight key advances in genitourinary cancers featured at the 2023 ASCO Annual Meeting, including the THOR study in mUCC, VESPER in muscle-invasive bladder cancer, CONTACT-03 in mRCC, and TALAPRO-2 in mCRPC. TRANSCRIPT  Dr. Rana McKay: Hello, and welcome to the ASCO Daily News Podcast. I'm Dr. Rana McKay, your guest host for the podcast today. I'm a GU medical oncologist at the Morris Cancer Center at the University of California in San Diego and an associate professor at the University of California in San Diego School of Medicine. Joining me today is Dr. Jonathan Rosenberg, the chief of the Genitourinary Oncology Service at the Memorial Sloan Kettering Cancer Center in New York. We'll be discussing practice-changing studies and other key advances in genitourinary cancers that were featured at the 2023 ASCO Annual Meeting.   You'll find our full disclosures in the transcript of this episode, and disclosures of all guests featured on the ASCO Daily News Podcast are available on our transcripts at asco.org/DNpod.  Jonathan, it's great to have you with us today. How are you?  Dr. Jonathan Rosenberg: I'm doing very well. Thanks so much for hosting today.  Dr. Rana McKay: Oh, of course. It's always fun to step back from ASCO and reflect on all the practice-changing and practice-informing studies that were presented.  Dr. Jonathan Rosenberg: Absolutely.  Dr. Rana McKay: Maybe we can dive right in with LBA4619. This is the much-talked-about THOR study of erdafitinib versus chemotherapy in patients with advanced or metastatic urothelial cancer with select FGFR alterations. What are your key takeaways from this study?  Dr. Jonathan Rosenberg: It is indeed a study we've been waiting for, for quite some time, to see the results in the confirmatory study after the accelerated approval of erdafitinib. This is half of the THOR trial. There were 2 cohorts of patients. One cohort were patients who previously received a checkpoint inhibitor randomized to chemotherapy or erdafitinib, and those data were reported at ASCO this year. The other cohort was randomized against a checkpoint inhibitor in patients who have not received a checkpoint inhibitor, and we'll see those data in a future meeting.   The bottom line for the THOR study is that FGFR3 inhibition improved overall survival compared with chemotherapy, and the chemotherapy in this study was a taxane. The overall survival was 12.1 months for erdafitinib compared to 7.8 months for chemotherapy with a hazard ratio of 0.64. This led to the DMC to stop the study and blind the data and cross people over. There was also a PFS advantage. There really weren't a lot of new toxicity signals seen; the usual suspects in terms of mucositis, hyperphosphatemia, diarrhea, dry mouth, and onycholysis.  And so, what it tells us ultimately is that in a patient who's progressed on a checkpoint inhibitor, we can feel comfortable about using erdafitinib knowing it provides a survival advantage in patients who've been previously treated for advanced urothelial cancer and have an FGFR alteration, either an FGFR2 or 3. And hopefully, we'll see more data in the future from the study, maybe not too long in the future from the other part of the study, comparing it to checkpoint inhibition.   Dr. Rana McKay: That's really exciting. I think it's exciting to see the data about the positivity of erdafitinib versus chemotherapy in this context. Looking at the phase 3 data is going to be really important. Looking at the data in the IO naive context is going to be really important. I feel like this sort of reaffirms what we've been doing in clinical practice. But how do you feel that the study is practice-changing?   Dr. Jonathan Rosenberg: I think it gives us reassurance that for these patients, erdafitinib is an appropriate option. There's no randomized data between erdafitinib and other choices, such as sacituzumab, which is also based on an accelerated approval, or enfortumab, which is based on randomized phase 3 trial. But it gives us level-1 evidence. I do wonder whether the comparison against the checkpoint inhibitor may turn out differently, but we'll see. Those data aren't in evidence. And I do think it was interesting that the majority of patients who were enrolled on the trial were PDL-1 low. We'll see what the comparison to a checkpoint inhibitor is like and whether those patients have similar characteristics.  Dr. Rana McKay: Yeah, you're almost kind of selecting for people that were not primed to respond.   Dr. Jonathan Rosenberg: Exactly.   Dr. Rana McKay: Well, that's really exciting, I think. Moving on to localized bladder cancer, Dr. Pfister presented the results of the VESPER trial. That's LBA4507. I think this study was really important. This was a trial that explored dose-dense MVAC with methotrexate, vinblastine, doxorubicin, and cisplatin or gemcitabine-cisplatin as a perioperative chemotherapy for muscle-invasive bladder cancer. I think there's always been some discussion around these regimens and how they pair up against one another. Can you tell us about these data?   Dr. Jonathan Rosenberg: It's a very interesting study. It was designed back when it was felt that we could not give patients neoadjuvant therapy. And it was designed as either a neoadjuvant or adjuvant approach. Although, in reality, almost everybody who was enrolled in the study got neoadjuvant chemotherapy, which I think speaks to the shift in practice over the last 10 to 15 years towards neoadjuvant rather than adjuvant therapy. It's an interesting trial in that it used a duration of chemotherapy for the MVAC regimen, the dose-dense MVAC regimen that we don't usually use, which is 6 cycles. And functionally, about 40% of patients couldn't make it to 6 cycles and had to stop sooner, versus 4 cycles of q3-week gemcitabine and cisplatin.   And what the data show is that the progression-free survival for the entire intent-to-treat population didn't reach significance. But if you looked at the neoadjuvant population only, there was an improvement in progression-free survival as well as overall survival. So, it's sort of a negative positive trial. Negative for the primary endpoint, but positive for key secondary endpoints. They did a very interesting analysis looking at the number of cycles that patients received regardless of arm, but looking at it by arm. And it's clear from that analysis that the more chemotherapy they got, the better they did.   Although, the flaw in that analysis is that the healthier patients are, the more chemotherapy they're able to tolerate, and therefore that may translate to an improved overall survival irrespective of the amount of chemotherapy. And this was not necessarily a pre-specified analysis. I think some of the statisticians were clutching their chests during the report of this trial, having talked to several afterward. On the other hand, it does say to me that for a fit, younger patient, it is important to consider dose-dense MVAC instead of gemcitabine and cisplatin.   I'll also note, reading the publication from the first part of the trial, that it appears that nobody over 70 was enrolled from everything I could tell. And so, I question the validity of the tolerability of the results for the average 75-year-old that I see in my practice. Although age is not a bright line cut-off for anybody in terms of cancer treatment. But my own experience has been that dose-dense MVAC has been harder to tolerate for a lot of patients in their 70s, whereas I think we should feel quite comfortable giving it to patients in their sixties. And if you ask me how many cycles I would give, I probably wouldn't say 6, for dose-dense MVAC, I would probably say 4.   Dr. Rana McKay: Was there a predilection that there was a more aggressive disease like nodal disease or other things to prompt the 6 versus 4?  Dr. Jonathan Rosenberg: I think that they stopped primarily for toxicity reasons, but it wasn't clear to me that it was a disease-based issue. And for the neoadjuvant therapy, everyone was supposed to be clinically node-negative on entry, so that probably wouldn't have explained it.  Dr. Rana McKay: Very exciting. I know that the data were quite provocative, but I think it's always difficult to interpret these sorts of subgroup of subgroup analyses, and there's a lot of bias in why people may get more versus less. And I think trying to reduce these data to clinical practice is going to be really important, as you've stated.  Dr. Jonathan Rosenberg: Rana, I'd also like to talk about some key advances in renal cell carcinoma that were reported at ASCO. Dr. Choueiri presented data on LBA4500, the CONTACT-03 study, which really was the first study of its kind in solid tumors because it addressed a major question in the kidney cancer field and in other fields: Is there a role for immunotherapy rechallenge after progression on immunotherapy? Specifically, the study looked at the efficacy and safety of atezolizumab plus cabozantinib versus cabozantinib alone after progression with prior immune checkpoint inhibitor therapy in metastatic RCC. I'd like you to tell me what you think of this study and the results and how they may affect our practice.   Dr. Rana McKay: Absolutely. This was a critically important study looking at the role of IO post-progression on IO. It was a large phase 3 trial that enrolled patients with clear cell and non-clear cell patients. It actually allowed patients with papillary RCC, unclassified RCC, to enroll in the study, whereas most of these studies are excluding patients with non-clear cell disease. Patients had to have progressed on an immune checkpoint inhibitor given either as adjuvant first line or second line, given either as a single agent or in combination with one of the other combos, whether a VEGF or IO. And patients were randomized one-to-one to receive the combination of atezolizumab plus cabozantinib versus cabozantinib alone. And the dosing of the cabozantinib here is at 60 milligrams in the combination, which is the standard dosing of cabozantinib monotherapy. And the primary endpoints for the trial included PFS and OS.   And in essence, this trial was a completely negative study. The primary endpoint, which was centrally reviewed, rPFS, was negative. The hazard ratio there was 1.03. Overall survival was also negative with a hazard ratio of 0.94. And when you look at the subgroup analyses, there really wasn't any specific subgroup that seemed to derive any benefit, potentially those that had a prior response to an immune checkpoint inhibitor, but in essence, a negative study.   And I think these data are really informative because the discussion at ASCO was conducted by Dr. David Braun, and he actually had conducted a very highly scientific Twitter poll to help guide how to interpret the data and what people do. And from that, about 30% of individuals that completed the poll were actually layering on IO therapy, and continuing IO therapy after somebody progressed on therapy layering in a TKI while keeping the IO backbone going.   And I think what this study proves is that we really don't have any really robust data to guide doing that at the present time. And what we may end up doing is compromising the efficacy of the oral TKI or dose-compromising the oral TKI to try to maintain an ineffective IO. And so, I think at the present time these data, while negative, were truly practice-informing. There are other studies that are looking at this strategy as well. I think one of the criticisms here is that atezolizumab really has not had a great track record in renal cell carcinoma in every single context where it was tested, either alone or in combination. It has not met its primary endpoint and it's not utilized as a treatment in RCC. So, there's some discussion that could this be the fact that this is a PDL-1 inhibitor and that it's atezolizumab. And additionally, I think the thing to point out for is that in the modern era if we look at the cabozantinib control arm, cabozantinib in the refractory setting had a PFS of 10.8 months, which is pretty impressive for a later line PFS, if you will. So, there is another study currently ongoing called the TiNivo-2 study that's looking at tivozanib plus nivolumab versus tivozanib alone in a similar patient population. That trial is enrolling only clear cell patients that had progressed on prior IO. So, I think we'll have additional data, but very, I think, informative. I think this question comes up in a lot in other tumor sites as well because of the broad use of checkpoint inhibitors across hematologic and solid tumor malignancies.   Dr. Jonathan Rosenberg: I think this was the most informative negative study and the most negative trial I've seen in a while as well. But it did highlight the importance of asking these questions where people assume they know the answer already, and in fact, we often don't, and our assumptions are wrong. So, I thought that was fascinating and very well described.    Staying in the kidneys arena. I'd like to talk to you also about the phase 2 KEYNOTE-B61, that's Abstract 4518. It looked at first-line lenvatinib and pembrolizumab across non-clear cell carcinomas. Tell me what you thought of the trial and what your takeaways were.   Dr. Rana McKay: This is an important study. I think the treatment of non-clear cell RCC has lagged. I guess the advances have lagged behind clear cell RCC, and really robust phase 3 randomized studies in people with non-clear cell histologies are very limited. This was a single-arm phase 2, so I think we need to kind of take that for what it's worth, that enrolled patients who had non-clear cell RCC per investigator that had received no prior systemic therapy. So, this was a frontline study, and patients received pembrolizumab plus lenvatinib until disease progression or toxicity.   The study enrolled a very robust 158 patients, which is pretty impressive for a modern-day non-clear cell cohort. We've seen data from nivo-cabo that had gotten presented previously by Dr. Lee. That study was a single institution, about 40 patients or so if you will. The primary endpoint of this study was objective response rate, and the bulk of the patients that were enrolled were papillary RCC. As you would imagine, around 60% of patients were papillary. It did include around 18% with chromophobe RCC. And when we break things down by IMDC risk category, about 44% of patients were favorable-risk disease. I think the percentage of patients who were favorable is higher than if we were to take an all-comer metastatic RCC patient population.   But the objective response rate was pretty impressive at 49% with this combination. The CR rate was right around 5.7%. So, I think certainly a pretty solid signal of efficacy. But again, this is a single-arm phase 2 study. I think what's also really interesting, and I think we have to take subset analyses with a grain of salt if you will, but there were responses that were seen across all histologies. And the prior nivo-cabo study that I had shared with you had previously done a futility analysis for patients with chromophobe RCC, and that cohort actually closed down. And in this study, the response rate for the chromophobe patients, though it wasn't a lot of patients, 29 patients with chromophobia RCC, was around 27.6%, so I think these data are certainly informative. If you look at the waterfall plot, there were some deep responses that were certainly observed, and the bulk of patients had some degree of tumor shrinkage with very little patients that had primary PD.   Dr. Jonathan Rosenberg: It's really provocative. So, are we getting to a point where we might start thinking about randomized trials in the non-clear cell population to try to establish the best standard of care?  Dr. Rana McKay: Well, I think PAPMET2 is currently enrolling patients. That study is looking at the combination of cabozantinib with atezolizumab versus cabozantinib alone for frontline papillary. PAPMET1, which was led by Dr. Pal, I mean, these studies are really magnanimous because it takes all hands on deck to get these patients enrolled because they're few and far between. So, I definitely think we need to be moving in that direction. And I think we need to be moving away from lumping all non-clear cells into one bucket because I think what we're seeing is that, one, the biology of these tumors is very distinct and unique, and they don't all behave the same to any one given therapy. So, we really need to move away from just lumping all non-clear cells into one bucket and try to actually conduct studies for each specific subtype.    Dr. Jonathan Rosenberg: Understood and agree. Let's switch gears for a second and talk about prostate cancer. Can you talk about the data from Abstract 5004, the TALAPRO-2 study of talazoparib and enzalutamide compared to placebo and enzalutamide as a first-line treatment with metastatic CRPC that have HR homologous recombination repair gene alterations?    Dr. Rana McKay: Absolutely. So the TALAPRO-2 study is one of three studies that have looked at the combination of PARP inhibitors with an ARSI in the frontline mCRPC setting. And this trial randomized patients to talazoparib and enzalutamide versus placebo enzalutamide. And again, this was first-line mCRPC. Patients were allowed to have received prior docetaxel or prior abiraterone in the castration-sensitive setting, and the primary endpoint was overall survival.  At GU ASCO this year, we saw the top-line data from TALAPRO-2 first get presented. And what was actually presented at this meeting was the subset of patients that were HRR-mutated only. They had two cohorts: an all-comer cohort that was previously presented, and then now they're presenting the subset of the patients that were HRR-mutated. And I think what we've seen across the board is that the efficacy of PARP inhibitors kind of differs by underlying HRR mutations.     When we look at the entire population of HRR-deficient patients, the study was positive, talazoparib plus enzalutamide resulted in an improvement in rPFS compared to enzalutamide placebo. The hazard ratio there was 0.45. And then when we break things down by selected gene groups, they did this subset analysis in patients with only BRCA1, only BRCA2, only PALB2, only CDK12, ATM CHEK2 if you will. The data are most robust for those patients with a BRCA1/2 alteration with hazard ratios of 0.17, 0.19. Again, this is for rPFS.     But then, when we look at some of these other mutations, like ATM CHEK2, hazard ratios are higher, 0.76, 0.90. So, the effect size really kind of drops off for those non-BRCA1/2 altered HRR genes. But if we look across the different subgroup analyses, the interim OS data for the HR deficient, the time to PSA, time to cytotoxic chemo, all of that favored the combination versus placebo enzalutamide for patients that were HR deficient if we just lumped everybody all together.  Dr. Jonathan Rosenberg: How does this fit into the general landscape around this question with selection versus not selecting for HRR alterations?  Dr. Rana McKay: The data that were presented were for the selected patients, and I think that that's not where the controversy is. I think that the selected patients are the ones that seem to derive the most benefit. It's interesting because in looking at the data from PROpel and the final FDA label based off of the PROpel data, the label is only for BRCA1 and 2 patients and not for all comer HRR. It's even a more restricted label than olaporib monotherapy. So, I think it's going to be interesting. I don't know what the right answer is. I think it's going to be interesting to see how this is going to unfold for TALAPRO-2 and even for MAGNITUDE, if you will, like, how select is the selected population going to be. But at the present time, I think the label is what it is for olaparib plus abiraterone in those BRCA1/2 frontline. My hope is that this population is shrinking because everybody should be getting escalated in the metastatic hormone-sensitive setting, and we shouldn't be having people who are naive to an ARSI in frontline mCRPC.  Dr. Jonathan Rosenberg: Understood and agreed.   Dr. Rana Mckay: Well, thank you so much, Jonathan, for joining me today. It's really been a pleasure kind of going through all of the compelling advances in GU cancers from ASCO. I think it was a really exciting meeting, and thanks for your time. Dr. Jonathan Rosenberg: My pleasure. It's been great to talk to you today.     Dr. Rana Mckay: And thank you to our listeners for your time today.

Dr. John Sweetenham and Dr. Neeraj Agarwal discuss advances across the spectrum of malignancies, including key studies in precision oncology and disparities in cancer care in advance of the 2023 ASCO Annual Meeting.  TRANSCRIPT Dr. John Sweetenham: Hello, I'm Dr. John Sweetenham, now the associate director for cancer network clinical affairs at UT Southwestern's Harold C. Simmons Comprehensive Cancer Center, and host of the ASCO Daily News Podcast. I'm delighted to welcome Dr. Neeraj Agarwal, director of the Genitourinary Oncology Program and a professor of medicine at the University of Utah Huntsman Cancer Institute, who is editor-in-chief of the ASCO Daily News.  Today we'll be discussing some key advances across the spectrum of malignancies, as well as novel approaches in precision medicine and cancer disparities that will be featured at the 2023 ASCO Annual Meeting.  Our full disclosures are available in the transcript of this episode, and disclosures of all guests on the podcast can be found on our transcripts at asco.org/DNpod.  Neeraj, it's great to have you back on the podcast today. Dr. Neeraj Agarwal: Thank you so much, John, for having me. Dr. John Sweetenham: Neeraj, let's begin by discussing some practice-changing phase 3 trials, starting with Abstract 5500, the KEYNOTE-826 study. This study reports the final overall survival results from a randomized, double-blind, phase 3 study of pembrolizumab plus chemotherapy versus placebo plus chemotherapy for first-line treatment of persistent, recurrent, or metastatic cervical cancer, which will be presented by Dr. Bradley Monk.  Dr. Neeraj Agarwal: I'd be happy to. The initial analysis of the KEYNOTE-826 study revealed that first-line pembrolizumab plus chemotherapy provided significant improvements in the overall survival and progression-free survival compared to placebo plus chemotherapy in patients with metastatic, persistent, or recurrent cervical cancer who had not previously received systemic chemotherapy and were not candidates for curative treatments such as surgery or radiation. In this study, patients were randomly assigned in a 1:1 ratio to receive pembrolizumab or placebo at 200 milligrams every three weeks for up to 35 cycles, along with chemotherapy with paclitaxel, plus a platinum therapy with or without bevacizumab.   From November 2018 to January 2020, 617 patients were enrolled with 308 receiving pembrolizumab plus chemotherapy and 309 patients receiving placebo plus chemotherapy. At the data cutoff of October 3, 2022, the median follow-up was 39 months. At this protocol-specified final overall survival analysis, pembrolizumab plus chemotherapy treatment continues to show a significant improvement in overall survival and progression-free survival, regardless of whether patients receive bevacizumab or not. The incidence of grade 3 or more adverse events was higher in the pembrolizumab plus chemotherapy arm than the placebo plus chemotherapy arm, with the most common adverse event being anemia, neutropenia, and hypertension. Dr. John Sweetenham: These are exciting data, Neeraj. So the main message from this trial is that pembrolizumab plus chemotherapy, with or without bevacizumab, can now be considered as standard of care for first-line treatment of persistent, recurrent, or metastatic cervical cancer. Dr. Neeraj Agarwal: Yes, I agree, John. Now, moving on to a different common type of cancer, let's discuss Abstract 1001, titled “Second-Line Endocrine Therapy with or without Palbociclib Maintenance in Patients with Hormone Receptor-Positive/HER2-Negative Advanced Breast Cancer: Results from the PALMIRA Trial,” which will be discussed by Dr. Antonio Llombart-Cussac. So, John, based on this abstract, can you please tell us about the role of palbociclib after prior progression on this drug? Dr. John Sweetenham: Yes. In this study, the authors aimed to determine if palbociclib maintenance with an alternative endocrine therapy improves the anti-tumor activity of second-line treatment in patients with endocrine-sensitive hormone receptor-positive and HER2-negative advanced breast cancer who had disease progression to first-line treatment with palbociclib in combination with endocrine therapy. After including 198 patients in the trial with a 2:1 randomization, 136 patients received palbociclib with endocrine therapy and 62 patients received endocrine therapy alone. And at a median follow-up of 8.7 months, the primary endpoint of progression-free survival was not met with a median progression-free survival of 4.2 months in the palbociclib-containing combination versus 3.6 months in the control arm. Also, higher grade 3 to 4 adverse events were reported in patients treated in the palbociclib arm. Dr. Neeraj Agarwal: Thanks, John. So you are saying that continuing the CDK4/6 inhibitor palbociclib after prior disease progression on palbociclib, even when the primary endocrine therapy has been changed, doesn't seem to be beneficial, therefore, this practice may be discouraged in the clinical setting? Dr. John Sweetenham: Yes, that's correct. Neeraj, I think that's the conclusion from this study. Dr. Neeraj Agarwal: So, John, now let's switch gears and highlight some precision oncology studies.  Dr. John Sweetenham: Well, Abstract 3602, titled “Real World Rates of FDA-Approved Targeted Therapy and Immunotherapy Prescriptions for Metastatic Colorectal Cancer Patients in the VA's National Precision Oncology Program” will be presented by Dr. Alice Nono Djosta. Can you tell us more about this abstract, Neeraj? Dr. Neeraj Agarwal: Well, comprehensive genomic profiling has the potential to guide the administration of FDA-approved biomarker-directed therapies and improve outcomes among patients with metastatic colorectal cancer. So, in this study, Abstract 3602, investigators sought to determine the rates of actionable biomarkers and prescription of associated FDA-approved therapies among veterans in the National Precision Oncology Program. Patients with metastatic colorectal cancer who had undergone comprehensive genomic profiling via tissue or liquid biopsy were included between 2019 and 2022 and had 1 of the following 5 actionable biomarker profiles including: NRAS, KRAS, BRAF wild-type, BRAF V600E mutation, MSI-high, TMB-high, NTRK fusion or rearrangements.  Prescription data for seven FDA-approved biomarker-directed therapies were extracted and rates of comprehensive genomic profiling (CGP)-directed therapy prescriptions were assessed by the investigators. A total of 908 patients with metastatic colorectal cancer underwent comprehensive genomic profiling, with 80% patients having colon adenocarcinoma and 20% with rectal adenocarcinoma. The combined rates of any actionable variants were 47% in patients with colon adenocarcinoma and 45% in patients with rectal adenocarcinoma. After including 424 eligible patients for FDA-approved biomarker therapy, only 70% patients with MSI-high, 48% patients with TMB-high, 38% patients with NRAS, KRAS, and BRAF wild-type, and only 17% of patients with BRAF V600E mutation received FDA-approved CGP-directed therapies.  Dr. John Sweetenham: Very important data, Neeraj. What's the main conclusion of this study? Dr. Neeraj Agarwal: So, in conclusion, this study found that almost 30% of patients with MSI-high metastatic colorectal cancer did not receive effective immune checkpoint inhibitors. And overall, a significant number of eligible patients did not receive FDA-approved biomarker-directed therapies. So, it is crucial that we evaluate the barriers to prescribing comprehensive genomic profiling-directed therapies in our patients with metastatic colorectal cancers.  So, John, let's move on to lung cancer, where the use of single-gene testing is still common in the community practice. Can you please tell us about Abstract 6506, titled “The Impact of Single-Gene Testing on Subsequent Comprehensive Genomic Profiling Success in Community Oncology Practice for Advanced Non–small Cell Lung Cancer”? These are results from a prospective observational reference laboratory testing program and these results will be presented by Dr. Mary Nesline. Dr. John Sweetenham: Yes, definitely. In this study, researchers aim to investigate the impact of prior single-gene testing on comprehensive genomic profiling success and therapeutic opportunities for patients with non–small cell lung cancer in community settings. They included patients who underwent at least 1 single gene testing for guideline recommending genomic variants in non–small cell lung cancer such as BRAF, EGFR, KRAS, MET exon 14 skipping mutations, ALK, RET, and ROS1 rearrangements as well as PD-L1 immunohistochemistry.  And they offered comprehensive genomic profiling either before or after receipt of a negative single gene test. Of 580 patients with non–small cell lung cancer with the comprehensive genomic profiling ordered between 2021 and 2022, around 30% of the patients had at least 1 single-gene testing ordered prior to the comprehensive testing, with a median of 5 prior single-gene tests. Compared to CGP-only cases. CGP per cases with prior negative single gene testing was canceled twice as often at tissue review, had a higher DNA extraction failure, and a lower DNA sequencing success. CGP also identified guideline-recommended variants in genes with no single-gene testing offered during the study period, such as ERBB2 mutations, or NTRK2/3 fusions, as well as variants targeted in ongoing clinical trials in 28% of patients. Dr. Neeraj Agarwal: Very interesting. So John, what is your key takeaway message from this? Dr. John Sweetenham: The main message is that in a community oncology setting, the practice of ordering single gene testing prior to comprehensive genomic profiling for patients with non–small cell lung cancer is common. Prior negative single-gene testing led to a higher rate of CGP test cancellation due to tissue insufficiency and increased CGP DNA extraction failures. The practice of single-gene testing does not align with practice guideline recommendations and may negatively impact the potential benefits of CGP testing for patients with non–small cell lung cancer.  Now, let's move on to another important abstract that our fellow clinicians should hear about. This is Abstract 1534 titled “Real-World Experience of an In-House Dihydropyrimidine Dehydrogenase Genotype Test to Guide Fluoropyrimidine Dosing at a Multi-Site Cancer Hospital” that will be presented by Dr. Jai Patel. Can you tell us more about this abstract, Neeraj? Dr. Neeraj Agarwal: Sure. Fluoropyrimidines, such as 5-fluorouracil and capecitabine, are commonly used to treat solid tumor cancers such as gastrointestinal and breast cancers. We know that severe toxicity occurs in one-third of patients, which delays the timely completion of treatments and result in prolonged hospitalization of these patients. These toxicities may be due in part to genetic variation in the DPYD gene. Five variants are known to have moderate to strong evidence according to the Clinical Pharmacogenetics Implementation Consortium. So, in this observational study, the authors describe the implementation of an in-house DPYD test and its impact on the dosing of these fluoropyrimidines, which include capecitabine and 5-fluorouracil.  From March 2020 to December 2022, 491 patients received DPYD genotyping testing, and 90% of them had gastrointestinal cancers. The median lab turnaround time was only 3 days. Pre-treatment testing was ordered in 80% of patients, and 93% of patients had results before starting cycle 1. Overall, 6% of patients were heterozygous carriers. Fluoropyrimidine dose was reduced, avoided, or discontinued in 90% of these patients. Moreover, in pre-treatment carriers, 90% of patients received an upfront dose reduction, avoidance, or they even declined chemotherapy. Dr. John Sweetenham: Thanks, Neeraj. So what do you think is the key takeaway message here? Dr. Neeraj Agarwal: So, DPYD genotype-guided dosing of fluoropyrimidine, including 5-fluorouracil and capecitabine, is logistically feasible with a rapid turnaround time and can result in treatment dose modifications for most carriers, potentially avoiding or mitigating severe toxicities, especially in those patients who received pre-treatment testing. Dr. John Sweetenham: Thanks again. Now let's transition to studies that focus on disparities in cancer care. Dr. Neeraj Agarwal: Definitely. Let's discuss Abstract 6530, titled “Impact of Free Hospital-Provided Rideshare Service on Radiation Therapy Completion Rates: A Matched Cohort Analysis.” In this study, Dr. Eric Chen and colleagues assess the potential of rideshare services in facilitating timely radiation therapy for patients facing barriers, such as limited transportation, financial constraints, and lack of adequate social support. So the authors analyzed data from about 2,900 patients who underwent radiation therapy and found that 58 of them utilized a free hospital-provided rideshare service.  These free hospital-provided rideshare service utilizers had a lower median age and were more likely to identify as Black or African American compared to those who did not utilize these services. They also had higher socioeconomic disadvantages and traveled shorter distances for treatment. Interestingly, more rideshare utilizers underwent radiation therapy with curative intent, had longer treatment course duration, and a higher number of fractions prescribed. In the matched-cohort analysis, the study found that radiation therapy completion rates were significantly higher for rideshare utilizers compared to non-rideshare utilizers, especially for patients who were undergoing radiation therapy with curative intent.  Dr. John Sweetenham: So what's the key take-home message from this abstract? Dr. Neeraj Agarwal: This study highlights the potential benefit of utilizing hospital-provided free ride-share services, particularly for patients facing barriers to timely treatment. So, using these services were associated with higher radiation therapy completion rates, especially in the curative setting.  So, John, there is another study, Abstract 1606, titled “Trends and Disparities in Oncology Telehealth after the Initial Pandemic Era” that will be presented by Dr. Michael Lee and colleagues. They evaluated whether telehealth utilization continued after the pandemic and if demographic differences in its users persist. So John, please tell us more about this abstract. Dr. John Sweetenham: Yes, the authors conducted a retrospective cohort study in 22 Kaiser Permanente Northern California hematology and oncology clinics between October 1, 2020, and June 1, 2022. The study investigated the use of office, video, and telephone visits, analyzing more than 340,000 hematology oncology visits with MD or DO providers. Of these visits, 25% were in-office, 37% were video visits, and 39% were telephone visits. Monthly telehealth visits peaked in January 2021, representing around 86% of total visits, and decreased to 69% of the total visits by June 2022. Video visits were more common for new appointments, whereas telephone visits were more common for return appointments. Moving to the post-pandemic period, telehealth visits remained popular, with video visits being the most commonly utilized. However, telehealth use varied among demographic populations. Video visits were a significantly higher proportion of all visits among individuals less than 45 years old, primary English speakers, patients with commercial insurance, non-Hispanic Whites and Asians, compared with Hispanic, Whites, and Blacks, and patients living in the deprived neighborhoods. Dr. Neeraj Agarwal: Interesting data, John. So what is the key takeaway message from this abstract? Dr. John Sweetenham: Well, overall, it's encouraging to see that even after the pandemic, telehealth continued to be widely used. However, the concerning issue is that telehealth is less utilized in patients who may need it most. The next step, in my view, will be to work on barriers to access telehealth by underprivileged populations.   And that brings our discussion to a close today. Before we wrap up the podcast, Neeraj, do you have any final thoughts to share? Dr. Neeraj Agarwal: Yes, thanks, John. I would urge our listeners to come and join us at the ASCO Annual Meeting, not only to celebrate these successes but also to help disseminate these cutting-edge data to practitioners and patients across the world. Dr. John Sweetenham: Absolutely. I'd like to thank our listeners for joining us today, and thank you, Neeraj, for sharing your insights with us as well.  You will find links to the abstracts discussed today on the transcripts of this episode.

Dr. Neeraj Agarwal and Dr. Jeanny Aragon-Ching discuss the CLEAR study in renal cell carcinoma, a new exploratory analysis combining the TheraP and VISION trials in metastatic urothelial cancer, and compelling advances in prostate cancer and across GU oncology in advance of the 2023 ASCO Annual Meeting.  TRANSCRIPT Dr. Neeraj Agarwal: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, your guest host for the ASCO Daily News Podcast today. I'm the director of the Genitourinary Oncology Program and a professor of medicine at the University of Utah Huntsman Cancer Institute, and editor-in-chief of the ASCO Daily News. I'm delighted to welcome Dr. Jeanny Aragon-Ching, a GU medical oncologist and the clinical director of the Genitourinary Cancers Program at the Inova Schar Cancer Institute in Virginia.   Today, we'll be discussing some key abstracts in GU oncology that will be featured at the 2023 ASCO Annual Meeting.  Our full disclosures are available in the show notes and disclosures of all guests on the podcast can be found on our transcript at asco.orgDNpod.   Jeanny, it's great to have you on the podcast today. Dr. Jeanny Aragon-Ching: Thank you so much, Dr. Agarwal, for having me. Dr. Neeraj Agarwal: Jeanny, let's begin with Abstract 4502 regarding long-term updated results on the CLEAR study. The abstract reports the final, prespecified overall survival analysis of the CLEAR trial, a four-year follow-up of lenvatinib plus pembrolizumab versus sunitinib in patients with advanced renal cell carcinoma. Dr. Jeanny Aragon-Ching: Yes, I would be happy to. So, just as a reminder, the combination of lenvatinib and pembrolizumab was initially approved by the FDA in August 2021 for first-line treatment of adult patients with advanced renal cell carcinoma. So, this was based on significant benefits that were seen in progression-free survival, which was a primary endpoint, but also showed improvement in the overall response rates compared with sunitinib in first-line advanced renal cell carcinoma.   So this abstract reports on longer-term follow-up now at a median of 49.8 months, and PFS favored the combination lenvatinib and pembrolizumab compared to sunitinib across all MSKCC risk groups, and PFS benefit versus lenvatinib and pembro compared to sunitinib was maintained with a hazard ratio of 0.47. And even overall survival was also maintained with the combination with a hazard ratio of 0.79, and the overall survival favored the combination across all risk groups. If we look at the CR rate, it was 18.3% for the combination compared to 4.8% with sunitinib, unless patients in the combination arm received subsequent anticancer therapies, and that's intuitive. And the PFS2 was also longer with the combination at 43 months compared to 26 months. Now, it is important to note that grade III or more treatment-related adverse events did occur in about 74% of the patients in the combination of lenvatinib and pembro, compared to 60.3% in patients with sunitinib. Dr. Neeraj Agarwal: Jeanny, this is good news. So the main message from the abstract is that sustained results from this combination of lenvatinib plus pembrolizumab are being seen even after a longer follow-up of more than four years.  Dr. Jeanny Aragon-Ching: Yes, I agree. So now, moving on, Neeraj, to a different setting in the RCC space, let's look at Abstract 4519, which is titled “Efficacy of First-line Immunotherapy-based Regimens in Patients with Sarcomatoid and/or Rhabdoid Metastatic Non-Clear Cell RCC: Results from the IMDC,” which will be discussed by Dr. Chris Labaki. So, Neeraj, based on this abstract, can you tell us a little bit more about the impact of these adverse pathologic risk features in non-clear cell RCC?  Dr. Neeraj Agarwal: Of course. So, using real-world patient data, the IMDC investigators compared the outcomes of patients with metastatic non-clear cell RCC who were treated with immunotherapy-based combination regimens versus those who were treated with VEGF-TKIs alone. They also assessed the impact of sarcomatoid and rhabdoid features on response to IO-based combinations versus VEGF-TKIs. Of 103 patients with metastatic non-clear cell RCC who had rhabdoid or sarcomatoid features, 32% of patients were treated with immunotherapy-based combinations.   After adjusting for confounding factors, the authors show that those treated with a combination of two immune checkpoint inhibitors or an immune checkpoint inhibitor with a VEGF-TKI combination had significantly improved overall survival, which was not reached in the immunotherapy combination group versus seven months within the VEGF-TKI group. Time to treatment failure and objective responses were also prolonged, significantly higher, and better in the immunotherapy groups compared with patients who were treated with VEGF-TKIs alone. Interestingly, if you look at those 430 patients with metastatic non-clear cell RCC who did not have sarcomatoid or rhabdoid features, they didn't seem to benefit with immunotherapy-based combinations.  Dr. Jeanny Aragon-Ching: This is an exciting update, Neeraj. What are the key takeaways from this abstract? Dr. Neeraj Agarwal: So the main takeaway is if you see a patient with advanced non-clear cell RCC who has sarcomatoid and rhabdoid features, there appears to be a rather substantial and selective benefit with IO-based combinations. And in this context, I would like to highlight the ongoing SWOG 2200 trial also known as PAPMET2 trial, which is comparing the combination of cabozantinib plus atezolizumab. So immuno-therapy-based combinations versus cabozantinib alone in advanced papillary renal cell carcinoma setting. So this trial is being led by Dr. Benjamin Maughan and Dr. Monty Pal. And I like to encourage our listeners to consider referring their patients for involvement in this federally funded trial so that we can validate the data from this retrospective study in a prospective way. So, Jeanny, let's now move on to another important disease type which is urothelial carcinoma. There is a very recent accelerated FDA approval of the drug combination of enfortumab vedotin and pembrolizumab for cisplatin-ineligible metastatic urothelial carcinoma patients. This is Abstract 4505, which is being presented by Dr. Shilpa Gupta and colleagues. Can you please tell us more about this update? Dr. Jeanny Aragon-Ching: Yeah, absolutely. So, as you mentioned, Neeraj, the FDA just granted accelerated approval in April 2023 for this combination of enfortumab vedotin or EV, which is and ADC, antibody drug conjugate against nectin-4 and the PD-1 inhibitor pembroluzimab. So it's a combination for patients with locally advanced or metastatic urothelial carcinoma who are considered cisplatin ineligible. So this is nearly a four-year follow-up.   So as a reminder, this was a phase 1b/2 trial that included 45 patients and it had a primary endpoint of safety and tolerability although the key secondary endpoints included confirmed overall responses, duration of response, progression-free survival, and the resist criteria was investigated via investigator and BICRs which is in a blinded independent central review. Even overall survival was a key secondary endpoint.  So, the bottom line was the confirmed overall response by BICR was 73.3%, the disease control rate was about 84%, and the CR rate was 15.6% with a PFS of close to 13 months, and a 12-month overall survival rate of 83%. However, it is important to cite that there were treatment-related adverse events including skin reactions in 66%, neuropathy occurred in 62%, and ocular disorders in 40%. And there was a little bit of pneumonitis in close to 9%, colitis, and hypothyroidism, so there are side effects to watch out for.  Dr. Neeraj Agarwal: So, Jeanny this is great. What is the key takeaway from this trial?  Dr. Jeanny Aragon-Ching: So I think the most important thing is we now have a new combination of EV and pembro which shows very promising responses and survival in part which led to the FDA accelerated approval in the cisplatin-ineligible population of patients. However, we must note that the phase 3 trial of EV302 will ultimately establish which approach is really beneficial for all of our cisplatin-ineligible patients, either a carboplatin-based chemotherapy regimen or a non-platinum-based regimen such as EV and pembro. Dr. Neeraj Agarwal: Thanks Jeanny, would you like to discuss any other study in the bladder cancer space? Dr. Jeanny Aragon-Ching: Absolutely. I think Abstract 4508 from Dr. Seth Lerner and colleagues will be very relevant to our colleagues. This abstract is SWOG S1011, which is a phase 3 surgical trial to evaluate the benefit of a standard versus an extended lymphadenectomy performed at the time of radical cystectomy for muscle-invasive bladder cancer.  Dr. Neeraj Agarwal: Yes. So this trial, as you said, is an important trial which randomized in a one-on-one fashion 618 patients with muscle-invasive bladder cancer undergoing radical cystectomy, and these patients were randomized to either standard lymph node dissection or an extended lymph node dissection. And standard lymph node dissection included, as we know, external and internal iliac and operative lymph node. The extended lymph node dissection included lymph nodes up to aortic bifurcation which included common iliac, presciatic, and presacral lymph nodes. At a median follow-up of approximately 6 years, there was no disease-free survival or overall survival benefit in patients undergoing an extended lymph node dissection compared to standard lymph node dissection. And extended lymph node dissection was also associated with greater morbidity and preoperative mortality. Dr. Jeanny Aragon-Ching: Very interesting data, Neeraj. So these results, I think, will be very useful for a lot of our surgical colleagues in both academia and the community who may still be inclined to perform extended lymphadenectomy during cystectomy. This study shows that it's actually not necessary. Dr. Neeraj Agarwal: Absolutely. So now let's move on to another disease type, which is very important - prostate cancer. There are several practice-informing abstracts that are worthwhile discussing. The first of these involves Abstract 5002, which looks at the impact of the PSA nadir as a prognostic factor after radiation therapy for localized prostate cancer, which will be presented by Dr. Praful Ravi and  colleagues. Jeannie, can you please tell us more about this abstract? Dr. Jeanny Aragon-Ching: Yeah, definitely. So this abstract, as you mentioned, Neeraj, is a prognostic impact of PSA nadir of more than or equal to 0.1 nanogram per ml within six months after completion of radiotherapy for localized prostate cancer - an individual patient data analysis of randomized trials from the ICECaP Collaborative. Basically, it refers to an attempt to evaluate early surrogate measures to predict for long term outcomes such as prostate cancer-specific survival, metastases-free survival, and overall survival. So they looked at a big registry from the ICECaP collaboration that included 10,415 patients across 16 randomized controlled trials. And those men underwent treatment for intermediate risk and high risk prostate cancer treated with either radiation therapy alone in about a quarter of patients, or they got RT with short-term ADT in about 58% of patients, and 17% of them got RT with long-term ADT.  So, after a median follow-up of ten years, what they found was, if you had a PSA nadir that is over or equal to 0.1 nanogram per ml within six months after completion of radiation therapy, it was associated with worse prostate cancer-specific survival, metastases-free survival, and overall survival. For instance, the five-year metastases-free survival for those who achieved a PSA nadir of less than 0.1 was 91% compared to those who did not, which was 79%. Therefore, they concluded that if you achieve a bad PSA of 0.1 or above within six months after you completed radiation, you had worse outcomes.  Dr. Neeraj Agarwal: Jeanny, what is the key takeaway message from this study? Dr. Jeanny Aragon-Ching: The key takeaway from this ICECaP analysis is that this information would be very important to augment a signal-seeking endpoint, especially for clinical trial development, so that we can develop further strategies to de-escalate for those who don't need systemic intensification or therapy intensification versus escalation for those who really do. Dr. Neeraj Agarwal: So, my radiation oncology colleagues need to watch out for those patients who do not achieve a PSA of less than 0.1 nanogram per ml within the first six months of finishing radiation therapy. Very interesting data.  Dr. Jeanny Aragon-Ching: Yes, absolutely. So. Neeraj another important abstract for our fellow clinicians, switching gears a little bit now, is Abstract 5011, which is titled “Do Bone Scans Overstage Disease Compared to PSMA PET?” This was an international, multicenter retrospective study with blinded, independent readers. Can you tell us more about this abstract? Dr. Neeraj Agarwal: Yes, a relatively small retrospective study, but still pertinent to our practice. So I'll summarize it. This study by Dr. Wolfgang Fendler and colleagues evaluated the ability of bone scans to detect osseous metastasis using PSMA PET scan as a reference standard. So in this multicenter retrospective study, 167 patients were included, of which 77 patients were at the initial staging of prostate cancer, 60 had biochemical recurrence after definitive therapy, and 30 patients had CRPC or castor-resistant disease.  These patients had been imaged with a bone scan and a PSMA PET scan within 100 days. And in all patients, the positive predictive value, negative predictive value and specificity for bone scan were evaluated at different time points. They had bone scan and PSMA PET scan and both were compared. And what they found was interesting. All these three values - positive predictive value, negative predictive value, and specificity for bone scan were 0.73, 0.82 and 0.82 in all patients, and in initial staging, it was even lower at 0.43 and 0.94 and 0.80.  So, without getting into too much detail regarding these numbers, I want to highlight the most important part of the study, that at the initial staging, 57% patients who had a positive bone scan had false positive bone scans. The interreader agreement for bone disease was actually moderate for bone scans and quite substantial for the PSMA PET scan.  Dr. Jeanny Aragon-Ching: So, Neeraj, what do you think is the key takeaway message here for our audience?   Dr. Neeraj Agarwal: The key takeaway message is that positive predictive value of bone scan was low in prostate cancer patients at initial staging, with the majority of positive bone scans being false positive. This suggests that a large proportion of patients which we consider to have low-volume metastatic disease by bone scan actually have localized disease. So in the newly diagnosed patients with prostate cancer, patients should ideally have a PSMA PET scan to rule out metastatic disease.   So, let's move on to another abstract I would like to discuss, which has important implications in treatment, especially now that lutetium 177 is approved, but frankly not available widely. Dr. Jeanny Aragon-Ching: Yeah, that's actually very timely. So the abstract you're referring to is 5045, which is being presented by Dr. Yu Yang Sun and colleagues entitled “Effects of Lutetium PSMA 617 on Overall Survival in TheraP Versus VISION Randomized Trials: An Exploratory Analysis.” So, Neeraj, can you tell us more about the relevance of this exploratory analysis? Dr. Neeraj Agarwal: Definitely. In this abstract, Dr. Yang Sun and colleagues assess the effect of lutetium PSMA on overall survival in two different trials, TheraP and VISION trials. So, just for our listeners' recollection, the phase 2 TheraP trial compared lutetium PSMA and cabazitaxel in patients with mCRPC who had progression on docetaxel and had significant PSMA avidity on gallium PSMA pet scan, which was defined as a minimum uptake of SUV max of 20 at least one site of disease and SUV max of more than 10 at all sites of measurable disease.  In this trial, 20 of 101 patients in the cabazitaxel arm crossed over to lutetium PSMA, and 32 of 99 patients in the lutetium PSMA arm crossed over to cabazitaxel. In the VISION trial, patients with mCRPC who previously progressed on at least one ARPI and one taxane-based therapy and had a positive gallium PSMA scan, and here, positivity was not stringently pre-specified as it was done in the context of TheraP trial. So, positive gallium pet scans were randomly assigned in two to one fashion to receive either lutetium PSMA plus best supportive care or standard of care versus standard of care.  And I'd like to highlight that the standard of care comprised ARPIs and bone protecting agents and these patients were not allowed to have cytotoxic chemotherapy such as cabazitaxel in the standard of care arm. Now, overall survival was similar in the lutetium PSMA group regardless of whether they got lutetium PSMA in the VISION trial or TheraP trial. There was no difference in overall survival with lutetium in the lutetium arms of VISION and TheraP trial with a hazard ratio of 0.92. And there was no difference in the overall survival between the lutetium PSMA and the cabazitaxel group in the TheraP trial if you use counterfactual analysis, assuming crossover had not occurred. So, quite interesting in my view. Dr. Jeanny Aragon-Ching: Yeah, thanks Neeraj for that wonderful synopsis and discussion. So, what is the key take home message then? Dr. Neeraj Agarwal: The main message in this new exploratory analysis, which combined both the TheraP and VISION trials, is that lutetium PSMA and cabazitaxel seem to be associated with similar overall survival benefit in these highly selected patients with PSMA positivity. Additionally, the difference in the observed effect of lutetium PSMA and overall survival in the TheraP and VISION trials may be actually better explained by the use of different treatments in the respective control arms of these trials. And these results, in my view, are quite pertinent for those patients and providers who do not have access to lutetium-177 therapy.  Let's go to another abstract that is currently relevant to our practice, given many patients with advanced prostate cancer who have concurrent diabetes; I'm talking about Abstract 5066. Jeanny, can you please tell us more about this abstract?  Dr. Jeanny Aragon-Ching: Certainly, Neeraj. So this abstract will be presented by Dr. Amy Shaver and colleagues. So it's also very relevant, since many men who are diagnosed with prostate cancer frequently also have a concomitant diagnosis of type 2 diabetes mellitus. So, this was a SEER-Medicare population database analysis that looked at men who were treated with either abiraterone or enzalutamide and also had concomitant diagnosis of type 2 diabetes mellitus (DM). And they were identified using ICD-9 and ICD-10 codes and they were all tied in to acute care utilization. So they looked at CMS research data codes and ER hospitalization visits six months after treatment initiation was recorded. So all in all, they took a sample of 11,163 men, of whom close to 62% were treated with abiraterone and about 38% were treated with enzalutamide.  So, of these, about 27% of them had type 2 DM, of whom 59% received abiraterone and about 41% had enzalutamide. So, the bottom line is, compared to those without diabetes mellitus, those who had type 2 diabetes had worse acute care utilization, which was 43% higher than those who got abiraterone compared to enzalutamide, and also had higher overall mortality. Therefore, the bottom line is, having type 2 diabetes mellitus, unfortunately, portends worse outcomes in men with prostate cancer, so careful attention needs to be paid to those who are starting out already with such comorbidities. So Neeraj, any final thoughts you have regarding this abstract and overall before we wrap up on the podcast today?  Dr. Neeraj Agarwal: Absolutely. So it looks like, based on this very important pertinent Abstract 5066, which talks about the impact of diabetes on our patients, I think we need to be very watchful regarding the impact of diabetes on our patients who are being treated with abiraterone or enzalutamide, especially drugs which are known to make the metabolic syndrome and diabetes worse. I think close monitoring and close attention to control of diabetes is very important. So with that, I would urge the listeners to come and join us at the Annual Meeting, not only to celebrate these successes but also to help disseminate this cutting-edge data to practitioners and maximize the benefit to our patients across the globe.   And thank you to our listeners for joining us today.

Otra semana, otro episodio. Quisiera ser Hector Lavoe, pero me siento el Aveo de Hector.

In this episode of ASCO Educational podcasts, we'll explore how we interpret and integrate recently reported clinical research into practice. The first scenario involves a 72-year old man with high-risk, localized prostate cancer progressing to hormone-sensitive metastatic disease.  Our guests are Dr. Kriti Mittal (UMass Chan Medical School) and Dr. Jorge Garcia (Case Western Reserve University School of Medicine). Together they present the patient scenario (1:12), review research evidence regarding systemic and radiation therapy for high-risk localized disease (5:45), and reflect on the importance of genetic testing and (10:57) and considerations for treatment approaches at progression to metastatic disease (16:13).  Speaker Disclosures Dr. Kriti Mittal:  Honoraria – IntrinsiQ; Targeted Oncology; Medpage; Aptitude Health; Cardinal Health  Consulting or Advisory Role – Bayer; Aveo; Dendreon; Myovant; Fletcher; Curio Science; AVEO; Janssen; Dedham Group  Research Funding - Pfizer Dr. Jorge Garcia:  Honoraria - MJH Associates: Aptitude Health; Janssen Consulting or Advisor – Eisai; Targeted Oncology Research Funding – Merck; Pfizer; Orion Pharma GmbH; Janssen Oncology;  Genentech/Roche; Lilly  Other Relationship - FDA Resources  ASCO Article: Implementation of Germline Testing for Prostate Cancer: Philadelphia Prostate Cancer Consensus Conference 2019 ASCO Course: How Do I Integrate Metastasis-directed Therapy in Patients with Oligometastatic Prostate Cancer?

Today we'll explore how we interpret and integrate recently reported clinical research into practice, focusing on two clinical scenarios: localized prostate cancer progressing to hormone-sensitive metastatic disease; and a case of de novo metastatic hormone-sensitive prostate cancer progressing to castration-resistant disease.   My name is Kriti Mittal and I am the Medical Director of GU Oncology at the University of Massachusetts. I am delighted to co-host today's discussion with my colleague, Dr. Jorge Garcia. Dr. Garcia is a Professor of Medicine and Urology at Case Western Reserve University School of Medicine. He is also the George and Edith Richmond Distinguished Scientist chair and the current chair of the Solid Tumor Oncology Division at University Hospital's Seidman Cancer Center. Let me begin by presenting the first patient scenario.  Case 1: A 72-year-old male was referred to urology for evaluation of hematuria. A rectal exam revealed an enlarged prostate without any nodules. A CT urogram was performed that revealed an enlarged prostate with bladder trabeculations. A cystoscopy revealed no stones or tumors in the bladder, but the prostatic urethra appeared to be abnormal looking. Transurethral resection of the prostate was performed. The pathology revealed Gleason score 4+5=9 prostate cancer, involving 90% of the submitted tissue. PSA was performed one week later and was elevated at 50. Patient declined the option of radical prostatectomy and was referred to radiation and medical oncology.   So I guess the question at this point is, Dr. Garcia, in 2023, how do you stage patients with high-risk localized prostate cancer and how would you approach this case? Dr. Jorge Garcia: That's a great question and a great case, by the way, sort of what you and I in our practice will call ‘bread and butter'. Patients like this type of case that you just presented come from different places to our practice.  So either they come through urology or oftentimes they may come through radiation oncology. And certainly, it depends where you practice in the United States, at ‘X', US, they may come through medical oncology.   So I think that the first question that I have is in whatever role I'm playing in this case, where the patient has seen a urologist or a rad onc or me first, I think it's important for us in medical oncology, at least in the prostate cancer space, to talk about how do we think of their case and put those comments into context for the patient. It's very simple for you to tell a patient you can probably have surgery, radiation therapy, but at the end of the day, how do you counsel that patient as to the implications of the features of his disease is going to be really important. I use very simple examples that I relate to my patients, but really this patient is a patient that has very high-risk prostate cancer based upon the NCCN guidelines and how we actually stratify patients into what we call low-risk, intermediate-, and high-risk, and between those very low and very high risk.  So his PSA is high, very high, I would argue. His Gleason score, now, what we call group grading is high. He has high-volume disease. So the first question that I would have is, what are the choices for treatment for a patient like this? But even before you and I may talk about treatment options, we really want to understand the volume of their disease and whether or not they have localized prostate cancer with high-risk features or whether or not they have locally advanced or hopefully not metastatic disease. So back in the days prior to the FDA approval for PSMA PET imaging, we probably will have a Technetium-99 whole-body bone scan, and/or we probably will actually use CT scanning. Most people in the past, we used to do just a CT of the abdomen and pelvic region. As you know, with the movement of oral agents in the advanced setting, I think most of us will do a chest CT, abdomen and pelvic region, and certainly we also probably will have a Technetium-99 bone scan.  Now, with the utility and the use of PET imaging, I think most people like him will probably undergo PET PSMA, where you use F-18 PSMA or Gallium-68 PSMA. I think the importance depends on how you look at the approval of these two technologies. I think that PET PSMA imaging is here to stay. It's probably what most of us will use. And based upon that, we will define yet the truest stage of this patient. So right now, what we know is he has high-risk features. Hopefully, their disease is localized. We'll probably put the patient through an imaging technology. If you don't have access to a PET, then obviously CT and a bone scan will do. But if you do, the PET will actually help us define if the patient has disease outside of the prostate region, in the pelvic area, or even if they have distant metastases. Dr. Kriti Mittal: I would agree with that approach, Dr. Garcia. I think in the United States, we've been late adopters of PSMA scans. I think this patient with high-risk localized disease, if insurance allows at our institution, would get a PSMA for staging. There are still some patients where insurance companies, despite peer-to-peer evaluations, are not approving PSMAs. And in those situations, the patient would benefit from conventional CTs and a bone scan. So let's say this patient had a PSMA and was found not to have any regional or distant metastases. He decided against surgery, and he is seeing you as his medical oncologist together with radiation. What would your recommendations be?  Dr. Jorge Garcia: I think the bigger question is, do we have any data to suggest or to demonstrate that if in the absence of metastatic disease with conventional imaging or with emerging technologies such as PSMA PET, there is no evidence of distant disease, which I think you probably agree with me, that would be sort of unlikely with a patient with these features not to have some form of PSMA uptake somewhere in their body. But let's assume that indeed then the PSMA PET was negative, so we're really talking about high-risk localized prostate cancer. So I don't think we can tell a patient that radical prostatectomy would not be a standard of care. We never had a randomized trial comparing surgery against radiation therapy. This patient has already made that decision and surgery is not an option for him. If he, indeed, had elected radiotherapy, the three bigger questions that I ask myself are where are you going to aim the beam of that radiation therapy? What technology, dose, and fractionation are you going to use? And lastly, what sort of systemic therapy do you need, if any, for that matter? Where we do have some data maybe less controversial today in 2023 compared to the past? But I think the question is, do we do radiation to the prostate only or do we expand the field of that radiation to include the pelvic nodes?  Secondly, do we use IMRT? Do you use proton beam or not? Again, that's a big question that I think that opens up significant discussions. But more important, in my opinion, is the term of hypofractionation. I think the field of radiation oncology has shifted away from the old standard, five, seven weeks of radiation therapy to more hypofractionation, which in simple terms means a higher dose over a short period of time. And there was a concern in the past that when you give more radiation on a short period of time, toxicities or side effects would increase. And I think that there is plenty of data right now, very elegant data, demonstrated that hypofractionation is not worse with regards to side effects. I think most of us will be doing or supporting hypofractionation. And perhaps even to stretch that, the question now is of SBRT. Can we offer SBRT to a selected group of patients with high-risk prostate cancer? And again, those are discussions that we will naturally, I assume, in your practice, in your group, you probably also have along with radiation oncology.  Now, the bigger question, which in my mind is really not debatable today in the United States, is the need for systemic therapy. And I think we all will go back to the old data from the European EORTC data looking at the duration of androgen deprivation therapy. And I think most of us would suggest that at the very least, 24 months of androgen deprivation therapy is the standard of care for men with high-risk prostate cancer who elect to have local definitive radiation therapy as their modality of treatment. I think that whether or not it's 24 or 36, I think that the Canadian data looking at 18 months didn't hit the mark. But I think the radiation oncology community in the prostate cancer space probably has agreed that 24 months clinically is the right sort of the sweetest spot.  What I think is a bit different right now is whether or not these patients need treatment intensification. And we have now very elegant data from the British group and also from the French group, suggesting, in fact, that patients with very high-risk prostate cancer who don't have evidence of objective metastasis may, in fact, benefit from ADT plus one of the novel hormonal agents, in this case, the use of an adrenal biosynthesis inhibitor such as abiraterone acetate. So I think in my practice, what I would counsel this patient is to probably embark on radiotherapy as local definitive therapy and also to consider 24 months of androgen deprivation therapy. But I would, based upon his Gleason score of group grading, his high-volume disease in the prostate gland, and his PSA, to probably consider the use of the addition of abiraterone in that context. Dr. Kriti Mittal: That is in fact how this patient was offered treatment. The patient decided to proceed with radiation therapy with two years of androgen deprivation. And based on data from the multi-arm STAMPEDE platform, the patient met two of the following three high-risk features Gleason score >8, PSA >40, and clinical >T3 disease. He was offered two years of abiraterone therapy. Unfortunately, the patient chose to decline upfront intensification of therapy. In addition, given the diagnosis of high-risk localized prostate cancer, the patient was also referred to genetic counseling based on the current Philadelphia Consensus Conference guidelines. Germline testing should be considered in patients with high-risk localized node-positive or metastatic prostate cancer, regardless of their family history. In addition, patients with intermediate-risk prostate cancer who have cribriform histology should also consider germline genetic testing.  Access to genetic counseling remains a challenge at several sites across the US, including ours. There is a growing need to educate urologists and medical oncologists to make them feel comfortable administering pretest counseling themselves and potentially ordering the test while waiting for the results and then referring patients who are found to have abnormalities for a formal genetics evaluation. In fact, the Philadelphia Consensus Conference Guideline offers a very elegant framework to help implement this workflow paradigm in clinical practice. And at our site, one of our fellows is actually using this as a research project so that patients don't have to wait months to be seen by genetics. This will have implications, as we will see later in this podcast, not only for this individual patient as we talk about the role of PARP inhibitors but also has implications for cascade testing and preventative cancer screening in the next of kin. Dr. Jorge Garcia: Dr. Mittal, I think that we cannot stress enough the importance of genetic testing for these patients. Oftentimes I think one of the challenges that our patients are facing is how they come into the system. If you come through urology, especially in the community side, what I have heard is that there are challenges trying to get to that genetic counsel. Not so much because you cannot do the test, but rather the interpretation of the testing and the downstream effect as you're describing the consequences of having a positive test and how you're going to counsel that patient. If you disregard the potential of you having an active agent based upon your genomic alteration, is the downstream of how your family may be impacted by a finding such as the DNA repair deficiency or something of that nature. So for us at major academic institutions because the flow how those patients come through us, and certainly the bigger utilization of multi-disciplinary clinics where we actually have more proximity with radiation oncology urology, and we actually maybe finesse those cases through the three teams more often than not, at least discuss them, then I think that's less likely to occur. But I think the bigger question is the timing of when we do testing and how we do it.  So there are two ways -- and I'd love to hear how you do it at your institution -- because there are two ways that I can think one can do that. The low-hanging fruit is you have tissue material from the biopsy specimen. So what you do, you actually use any of the commercial platforms to do genomic or next-generation sequencing or you can do in-house sequencing if your facility has an in-house lab that can do testing. And that only gets you to what we call ‘somatic testing', which is really epigenetic changes over time that are only found in abnormal cells. It may not tell you the entire story of that patient because you may be missing the potential of identifying a germline finding. So when you do that, did you do germline testing at the same time that you do somatic testing or did you start with one and then you send to genetic counseling and then they define who gets germline testing? Dr. Kriti Mittal: So at our site, we start with germline genetic testing. We use either blood testing or a cheek swab assay and we send the full 84-gene multigene panel. Dr. Jorge Garcia: Yeah, and I think for our audience, Dr. Mittal, that's great. I don't think you and I will be too draconian deciding which platform one uses. It's just that we want to make sure that at least you test those patients. And I think the importance of this is if you look at the New England Journal paper from many years ago, from the Pritchard data looking at the incidence of DNA repair deficiency in men with prostate cancer in North America, that was about what,  around 10% or so, take it or leave it. So if you were to look only for germline testing, you only will, in theory, capture around 10% of patients. But if you add somatic changes that are also impacting the DNA pathway, then you may add around 23%, 25% of patients. So we really are talking that if we only do one type of testing, we may be missing a significant proportion of patients who still may be candidates, maybe not for family counseling if you had a somatic change, rather than germline testing, the positivity, but if you do have somatic, then you can add into that equation the potential for that patient to embark on PARP inhibitors down the road as you stated earlier. It may not change how we think of the patient today, or the treatment for that matter. But you may allow to counsel that patient differently and may allow to sequence your treatments in a different way based upon the findings that you have. So I could not stress the importance of the NCCN guidelines and the importance of doing genetic testing for pretty much the vast majority of our patients with prostate cancer. Dr. Kriti Mittal: Going back to our patient, three years after completion of his therapy, the patient was noted to have a rising PSA. On surveillance testing, his PSA rose from 0.05 a few months prior to 12.2 at the time of his medical oncology appointment. He was also noted to have worsening low back pain. A PSMA scan was performed that was noteworthy for innumerable intensely PSMA avid osseous lesions throughout his axial and appendicular skeleton. The largest lesion involved the right acetabulum and the right ischium. Multiple additional sizable lesions were seen throughout the pelvis and spine without any evidence of pathologic fractures. So the question is, what do we do next? Dr. Jorge Garcia: The first question that I would have is, the patient completed ADT, right? So the patient did not have treatment intensification, but at the very least he got at least systemic therapy based upon the EORTC data. And therefore, one would predict that his outcome will have been improved compared to those patients who receive either no ADT or less time on ADT. But what I'm interested in understanding is his nadir PSA matters to me while he was on radiation and ADT. I would like to know if his nadir PSA was undetectable, that's one thing. If he was unable to achieve an undetectable PSA nadir, that would be a different thought process for me.   And secondly, before I can comment, I would like to know if you have access to his testosterone level. Because notably, what happens to patients like this maybe is that you will drive down testosterone while you get ADT, PSAs become undetectable. Any of us could assume that the undetectability is the result of the radiation therapy. But the true benefit of the combination of radiation and ADT in that context really comes to be seen when the patient has got off the ADT, has recovered testosterone, and only when your testosterone has normalized or is not castrated, then we'll know what happens with your serologic changes. If you rise your PSA while you recover testosterone, that is one makeup of patient. But if you rise your PSA while you have a testosterone at the castrated level, that would be a different makeup of a patient. So do we have a sense as to when the patient recovered testosterone and whether or not if his PSA rose after recovery?  Dr. Kriti Mittal: At the time his PSA rose to 12, his testosterone was 275. Dr. Jorge Garcia: Okay, perfect. You and I would call this patient castration-naive or castration-sensitive. I know that it's semantics. A lot of people struggle with the castration-naive and castration-sensitive state. What that means really to me, castration-naive is not necessarily that you have not seen ADT before. It's just that your cancer progression is dependent on the primary fuel that is feeding prostate cancer, in this case, testosterone or dihydrotestosterone, which is the active metabolite of testosterone. So in this case, recognizing the patient had a testosterone recovery and his biochemical recurrence, which is the rising of his PSA occur when you have recovery of testosterone, makes this patient castration-sensitive. Now the PET scan demonstrates now progression of his disease. So clearly he has a serologic progression, he has radiographic progression. I assume that the patient may have no symptoms, right, from his disease?  Dr. Kriti Mittal: This patient had some low back pain at the time of this visit. So I think we can conclude he has clinical progression as well. Dr. Jorge Garcia: Okay, so he had the triple progression, serologic, clinical, and radiographic progression. The first order of business for me would be to understand the volume of his disease and whether we use the US CHAARTED definition of high volume or low volume, or whether we use the French definition for high volume from Latitude, or whether we use STAMPEDE variation for definition, it does appear to me that this patient does have high-volume disease. Why? If you follow the French, it's a Gleason score of >8, more than three bone metastases, and the presence of visceral disease, and you need to have two out of the three. If you follow CHAARTED definition, we did not use Gleason scoring, the US definition. We only use either the presence of visceral metastases or the presence of more than four bone lesions, two of which had to be outside the appendicular skeleton. So if we were to follow either/or, this patient would be high-volume in nature.  So the standard of care for someone with metastatic disease, regardless of volume, is treatment intensification, is you suppress testosterone with androgen deprivation therapy. And in this case, I'd love to hear how you do it in Massachusetts, but here, for the most part, I would actually use a GnRH agonist-based approach, any of the agents that we have. Having said that, I think there is a role to do GnRH antagonist-based therapy. In this case, degarelix, or the oral GnRH antagonist, relugolix, is easier to get patients on a three-month injection or six-month injection with GnRH agonist than what it is on a monthly basis. But I think it's also fair for our audience to realize that there is data suggesting that perhaps degarelix can render testosterone at a lower level, meaning that you can castrate even further or have very low levels of testosterone contrary to GnRH agonist-based approaches.  And also for patients maybe like this patient that you're describing, you can minimize the flare that possibly you could get with a GnRH agonist by transiently raising the DHT before the hypothalamic-pituitary axis would shut it down. So either/or would be fine with me. Relugolix, as you know, the attraction of relugolix for us right now, based upon the HERO data, is that you may have possibly less cardiovascular side effects. My rationale not to use a lot of relugolix when I need treatment intensification is quite simple. I'm not aware, I don't know if you can mitigate or minimize that potential cardiovascular benefit by adding abiraterone or adding one of the ARIs, because ARIs and abiraterone by themselves also have cardiovascular side effects. But either/or would be fine with me. The goal of the game is to suppress your male hormone.  But very important is that regardless of volume, high or low, every patient with metastatic disease requires treatment intensification. You can do an adrenal biosynthesis inhibitor such as abiraterone acetate. You can pick an androgen receptor inhibitor such as apalutamide or enzalutamide if that's the case. The subtleties in how people feel comfortable using these agents, I think, none of us – as you know, Dr. Mittal - can comment that one oral agent is better than the other one. Independently, each of these three oral agents have randomized level 1, phase III data demonstrating survival improvement when you do treatment intensification with each respective agent. But we don't have, obviously, head-to-head data looking at this.  What I think is different right now, as you know, is the data with the ARASENS data, which was a randomized phase III trial, an international effort looking at triple therapy, and that is male hormone suppression plus docetaxel-based chemotherapy against testosterone suppression plus docetaxel-based chemotherapy plus the novel androgen receptor inhibitor known as darolutamide. This trial demonstrated an outcome survival improvement when you do triple therapy for those high-volume patients. And therefore, what I can tell you in my personal opinion and when I define a patient of mine who is in need of chemotherapy, then the standard of care in my practice will be triple therapy. So if I know you are a candidate for chemotherapy, however, I make that decision that I want you to get on docetaxel upfront. If you have high-volume features, then the standard of care would not be ADT and chemo alone, it would be ADT, chemo, and darolutamide.  What I don't know, and what we don't know, as you know, is whether or not triple therapy for a high-volume patient is better, the same, equivalent, or less than giving someone ADT plus a novel hormonal agent. That is the data that we don't have. There are some meta-analyses looking at the data, but I can tell you that at the very least, if you prefer chemo, it should be triple therapy. If you prefer an oral agent, it certainly should be either apalutamide, abiraterone acetate, and/or enzalutamide. But either/or, patients do need treatment intensification, and what is perplexing to me, and I know for you as well, is that a significant proportion of our patients in North America are still not getting treatment intensification, which is really sub-optimal and sub-standard for our practice.  Dr. Kriti Mittal: Thank you, Dr. Garcia, for a terrific discussion on the application of recent advances in prostate cancer to clinical practice.

Guest host Dr. Neeraj Agarwal and Dr. Christian Kollmannsberger discuss practice-changing abstracts that were presented at the 2023 ASCO Genitourinary Cancers Symposium, including results from the TALAPRO-2, PROpel, TRITON3, ARASENS, KEYNOTE-057, CheckMate 274, and CheckMate 9ER studies. TRANSCRIPT Dr. Neeraj Agarwal: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, the director of the Genitourinary Oncology Program, and professor of Medicine at the Huntsman Cancer Institute at the University of Utah, and editor-in-chief of the ASCO Daily News.  Today, we will be discussing practice-changing abstracts and other key advances in GU Oncology featured at the 2023 ASCO Genitourinary Cancers Symposium. Joining me for this discussion is Dr. Christian Kollmannsberger, the chair of this year's ASCO GU. Dr. Kollmannsberger is a GU medical oncologist at the BC Cancer Vancouver Cancer Center and a clinical professor at the University of British Columbia.  Our full disclosures are available in the transcript of this episode, and the disclosures of all guests on the podcast can be found on our transcripts at asco.org/DNpod.  Christian, thank you for joining us on the podcast today.  Dr. Christian Kollmannsberger: Thank you very much, Neeraj. It's a real pleasure to be here and have this discussion. Dr. Neeraj Agarwal: Thank you. So, Christian, the GU meeting featured remarkable progress in various GU malignancies. Could you please share some of the prominent topics that made the headlines this year and give us an overall feel of ASCO GU this year? Dr. Christian Kollmannsberger: Absolutely. I think it was a great meeting with over 5,800 attendees from more than 70 countries. And most of the attendees were in person, so it was a great event. ASCO GU is truly the premier global event to feature the very best of GU cancer research and treatment. The theme of this year's meeting was "Today's Science, Tomorrow's Treatment," and that was reflected in the novel scientific and clinical findings that were presented and will potentially lead to changes in our daily clinical practice. It also reminds us how quickly the development today is and how quickly novel scientific progress is immediately translated into clinical practice, particularly oncology.   I was very impressed by the meeting's emphasis on diversity, interactivity, networking, multidisciplinary collaboration, and evidence-based care. We introduced several new features such as a “Meet the Professor session, a women's networking event, etc. And the first day really kicked off with a very rich focus on prostate cancer and much attention given to PARP inhibitors in our first session. As an example, LBA 17 was the first late-breaking abstract presented. And congratulations to you, Neeraj, on delivering this exciting data on the TALAPRO-2 trial, which were eagerly awaited. Let's start with that. Can you tell us about this trial? Dr. Neeraj Agarwal: Yes, of course. So the TALAPRO-2 trial was a phase 3 randomized trial where patients in newly diagnosed metastatic CRPC settings were randomized to standard of care enzalutamide plus placebo versus enzalutamide plus talazoparib PARP inhibitor. And as we know, Christian, the rationale has been that dual inhibition of PARP and AR may enhance the efficacy of each. And there's a laboratory preclinical rationale and based on which other studies have been done in the past. So, without getting into too much detail into the rationale for the trial, I'll come right to the results of the trial. So, this was the first-line mCRPC setting where rPFS was the primary endpoint as assessed by the independent radiology assessment. And in this trial, patients were recruited regardless of the homologous recombination repair gene alterations. So, patients were recruited and they were prospectively tested for whether they had these HRR gene alterations or not, but all comer population was included in this trial. And after a median follow-up of approximately 23 months, the trial read out, and we found that trial made the primary endpoint was improved radiographic progression-free survival with the rPFS being about 22 months in the enzalutamide arm and not reached in the combination arm with a 37% reduction in risk of progression or death.  If you look at the subgroup analysis of patients who were HRR+, there was a 54% reduction risk of progression or death. If you look at patients who were stratified in HRR- or unknown group, there was a 30% reduction risk of progression or death. If you specifically look at an exploratory analysis we did to look for patients who were HRR- by prospective tumor tissue testing; there was a 34% reduction in risk of death with a hazard ratio of 0.66 favoring the combination arm. So overall, the rPFS primary endpoint was met in all groups. We also see significant delay in PSA progression in the combination arm by more than nine months. We also see delays in the time to cytotoxic chemotherapy. We saw delay in progression or death on subsequent neoplastic therapy after the protocol treatment. We saw delays in deterioration of quality of life and global health status. All these were significant and happened on the talazoparib plus enzalutamide arm.  So overall, if you look at the totality of the data, these all favored the combination of talazoparib plus enzalutamide compared to enzalutamide alone. I want to highlight that overall survival is immature at 31% maturity with a hazard issue of 0.89, currently favoring enzalutamide plus talazoparib. But we'll have to look at more mature data as time passes.  Dr. Christian Kollmannsberger: Wow. Thank you, Neeraj. So, it sounds like that was a very positive trial, and it's potentially practice-changing. One of the concerns is always safety and toxicity. So can you tell us whether there were any new safety signals, and can you tell us more about the common adverse events that were noticed in TALAPRO-2? Dr. Neeraj Agarwal: No discussion is complete without talking about safety results, so I'm glad you asked me, Christian. The most common dose-affecting toxicity, if you will - so toxicities which led to dose modification and dose discontinuation of talazoparib were cytopenias, as we expect from this class of agents. So anemia, neutropenia, thrombocytopenia, these were the common toxicities. In fact, rate with anemia was 46.5%. Neutropenia and cytopenia were much less common.  I would like to highlight one fact which also came up during the discussion section after our oral presentation. The qualifying criteria for entry in this trial was a hemoglobin of 9-gram percent. And 49% of patients had grade 1 to 2 anemia at baseline, that is before starting treatment with talazoparib. So, we knew that if you mandate dose reduction, a lot of patients will not get adequate dosing of talazoparib. So, we waited for grade 3 anemia and then instituted dose reduction. And that I thought personally was a good strategy because the grade 3 anemia happened after a median duration of three months, 3.3 months to be more precise. And then, these patients underwent protocol-mandated dose reduction, following which the dose discontinuations were quite low actually. Only 8.3% patients discontinued talazoparib because of anemia, and the median dose intensity or median relative dose intensity of talazoparib in the talazoparib arm remained quite high at more than 80%, which translates to a talazoparib dose of 0.4 milligram daily when the starting dose was 0.5 milligram. So those were the hallmark of toxicities.   I do like to mention that those grade 3, 4 toxicities which are more known to affect the quality of life of our patients, such as grade 3, 4 anorexia, fatigue, nausea and vomiting, they were quite rare, happening in 1 to 4% patients who were on talazoparib. So overall, regarding the side effects, they were manageable, there were no new safety signals, and we could maintain adequate talazoparib dosing with dose reduction, which happened quite early during the protocol treatment.  Dr. Christian Kollmannsberger: Thank you, Neeraj. Very impressive results indeed. The patient population included in TALAPRO-2 was very similar to those included in the PROpel phase 3 trial, which tested the combination of abiraterone and olaparib in the first-line mCRPC setting. So, I'd like to just mention that we also saw LBA16 on the PROpel study, which was the final overall survival in PROpel, which was presented by Noel Clarke. So PROpel, as you know, was a randomized phase 3 trial evaluating efficacy and safety of olaparib plus abiraterone versus placebo plus abiraterone as first-line therapy for mCRPC in the first-line metastatic castration resistance setting. The enrollment in that study was independent of known defects in the homologous recombination repair gene pathway in contrast to other studies, such as MAGNITUDE, which tested the biomarker upfront. A total of 796 patients were randomly assigned to either olaparib plus abiraterone or placebo plus abiraterone. And we saw similar results, significant radiographic progression-free survival with olaparib plus abiraterone in PROpel, which was the primary endpoint similar to TALAPRO-2, and that was published last year in the New England Journal of Medicine Evidence.  Now, this abstract presented here at ASCO GU reported on overall survival with an overall survival majority of 47.9% and showed that with the addition of the PARP inhibitor olaparib to abiraterone, a statistically non-significant but clinically meaningful improvement in overall survival of about seven months were achieved compared to standard of care in abiraterone alone. The numbers were 42.1 versus 34.7 months in the all-comers population of patients in the first-line mCRPC setting. Importantly, I think the median overall survival of more than 42 months really represents the longest reported median overall survival thus far in a phase III trial for first-line metastatic castration-resistant prostate cancer. Although the median overall survival for the non-HRR group remains not statistically significant, with a hazard ratio of 0.89. Dr. Neeraj Agarwal: Such a great synopsis of the PROpel result data. Thank you, Christian, for highlighting these results. As we know, the combination is already approved by the EMA, the European Medical Agency, for patients in the first-line mCRPC setting who are not candidates for docetaxel chemotherapy. If this combination is approved by the FDA, we may have one more therapeutic option for our patients in first-line mCRPC.  So, just continuing on the PARP inhibitors, there was one more oral presentation with PARP inhibitor rucaparib by Dr. Alan Bryce from the Mayo Clinic, Arizona. This was Abstract 18 on the primary result of the TRITON3 trial. So to complete our PARP inhibitor section, I would like to summarize the result of the TRITON3 trial, which was a randomized phase III trial evaluating rucaparib versus physician choice, which notably included docetaxel in addition to abiraterone or enzalutamide in patients with chemotherapy-naive mCRPC with BRCA1, BRCA2 or ATM alterations. These patients had disease progression after having one novel hormonal therapy, or we call them second-generation androgen pathway inhibitors in any setting. So these patients had to have disease progression on a novel hormonal therapy.   In the BRCA subgroup and the subsequent intention to treat the population, the primary endpoint tested first was radiographic progression-free survival, and overall survival was the key secondary endpoint. The subgroup of patients with BRCA-altered disease had a median rPFS of 11.2 months with rucaparib compared to 6.4 months with physician choice of treatment - looks like almost doubling of the rPFS with the rucaparib. In the overall ITT population, median rPFS was 10.2 months with rucaparib and 6.4 months with the physician's choice of treatment. Although the overall survival data are immature, we still see a trend for improved overall survival with rucaparib. Regardless, the study clearly demonstrates the value of rucaparib for treating BRCA1 and BRCA2-altered mCRPC after disease progression on an androgen receptor pathway inhibitor. So these were the impressive results from the TRITON3 trial.  But before we switch to non-prostate abstract, I would like to complete the prostate cancer discussion by talking about the Abstract 15, which was based on the results of the ARASENS trial presented by Dr. Maha Hussain. As we know, ARASENS is a randomized phase 3 trial evaluating the efficacy and safety of darolutamide plus androgen deprivation therapy plus docetaxel versus androgen deprivation therapy or ADT plus docetaxel. So the triplet of ADT plus darolutamide plus docetaxel being compared to ADT plus docetaxel chemotherapy in patients with newly diagnosed metastatic castration-sensitive prostate cancer. A total of 1,300 patients were randomly assigned to the doublet versus triplet. As presented in the last ASCO GU meeting exactly one year ago, the primary endpoint of the study was met with a significant improvement in overall survival and a 32% reduction in risk of death for patients on the triplet therapy with ADT plus docetaxel plus darolutamide versus ADT plus docetaxel chemotherapy. So triplet therapy was already approved based on these data.  The abstract presented by Dr. Hussain this year is a post-talk analysis where Dr. Hussain and colleagues investigated the impact of triplet therapy across patients with high volume versus low volume per chartered criteria and higher risk versus low risk using latitude trial criteria. And investigators knew that these results would be highly attractive to practicing oncologists who are now choosing treatment based on volume of disease or risk of disease, more commonly, volume of disease.  So, let's come to what was presented this ASCO GU. So, after 1,305 patients in ARASENS, the majority had high-volume disease and high-risk disease. Among patients with high-volume disease, the addition of darolutamide reduced the risk of death by 30% compared with ADT and docetaxel, with a hazard ratio of 0.69. In the risk groups, the addition of darolutamide seems to favor both high-risk and low-risk groups. Among patients with low-volume disease, there was a trend towards improvement in overall survival with the addition of darolutamide, but it did not reach statistical significance. The great news was that there was no new safety signal. So, to summarize these data, the triplet of darolutamide plus ADT plus docetaxel showed superior overall survival compared to doublet of ADT plus docetaxel, with an important caveat that triplet was not compared with any of the modern doublets of ADT plus a second generation androgen receptor pathways inhibitor such as abiraterone, apalutamide, or enzalutamide, or even darolutamide. So, I wish there was a third arm of ADT plus darolutamide.  Having said that, triplet can be considered a standard of care now based on these data for patients with metastatic hormone sensory prostate cancer, where we would be using ADT plus docetaxel chemotherapy. And from this meeting data, this efficacy of triplet can be applied to high-volume disease and all risk disease. And we just need more time to see how the data pans out in low-volume patients with metastatic hormone-sensitive prostate cancer.  Dr. Christian Kollmannsberger: Yes, I completely agree, Neeraj. I think all the data presented in these abstracts are really impressive and will impact our daily clinical practice and our patients more or less immediately. I think the use of PARP inhibitors, whether as a monotherapy or in combination with androgen receptor pathway inhibitors, as well as now the option of triplet therapy in the metastatic castration sensitive setting really offer patients with metastatic prostate cancer new treatment strategies and most importantly, improved survival outcomes. And it is impressive to see how we have pushed the prognosis and the outcomes for our patients with prostate cancer, I would say, in the last five to ten years. And similar to last year, I think the entire Prostate Cancer Day at ASCO GU 2023 was full with impressive data and featured dynamic content throughout the day. Dr. Neeraj Agarwal: Indeed. So, let's move on to bladder cancer. Christian, what are your key takeaways from the bladder cancer studies presented at the meeting? Dr. Christian Kollmannsberger: I think there were interesting abstracts in both the non-muscle-invasive and the muscle-invasive setting and the metastatic setting. So, for example, Abstract 442 was presented by Dr. Andrea Necchi on the cohort B of the phase 2 KEYNOTE-057 trial. As a background here, the standard treatment for high-risk non-muscle-invasive bladder cancer involves transurethral resection of the bladder tumor, a TURBT, followed by intravesical BCG therapy to eradicate any residual disease. And patients who fail to adequately respond to BCG are usually recommended to undergo radical cystectomy. So in the cohort B of the phase 2  KEYNOTE-057 trial that investigated the safety and efficacy of pembrolizumab as a single agent for patients with BCG-unresponsive, high-risk non-muscle-invasive bladder cancer who were ineligible or declined to undergo radical cystectomy, enrolled patients received standard-dose pembrolizumab of 200 milligrams every three weeks for up to 35 cycles. So very common as we do it with other disease sites. And at a median follow-up of 45.4 months, the primary endpoints of disease-free survival at twelve months was 43.5%. The median disease-free survival duration was 7.7 months. These are encouraging results, and we should keep in mind that a radical cystectomy has immense impact on our patients' quality of life. So I think it is important that we do these trials.  Now in order to address potential biases in this phase II trial, such as the underlying heterogeneity of transurethral resection of bladder tumor quality, and to obtain a more comprehensive understanding of pembrolizumab's efficacy relative to a particular control group, we need further evaluation of pembrolizumab in a randomized trial before we can really go for regulatory approval. But overall, I think for the first time in a long time that we seem to be able to move the needle in non-muscle-invasive bladder cancer. Dr. Neeraj Agarwal: Thank you, Christian, for this great overview. Could you please also share the findings presented by Dr. Matt Galsky on Abstract 443? Dr. Christian Kollmannsberger: Of course, Neeraj. Abstract 443, presented by Matt Galsky, reported the extended follow-up results from the CheckMate 274 trial, which looked at another very important field where we haven't made that much progress, which is the adjuvant setting. And CheckMate 274 examined adjuvant nivolumab compared to placebo for patients with high-risk resected muscle-invasive urothelial carcinoma. In this trial, nivolumab was given at 240 milligrams every two weeks or placebo every two weeks for up to one year of treatment. After following up with patients for a median of 36.1 months, the study found that those who received nivolumab had a median DFS of 22 months compared to only 10.9 months for those who received placebo among the ITT patients. So basically, a doubling of the DFS with the addition of adjuvant nivolumab.  The results were particularly notable for patients with high PD-L1 expressions or PD-L1 expression of 1% or more, as those who are treated with nivolumab had a median DFS of 52.6 months, which was six times higher than the DFS in the control group where patients received placebo, which was only 8.4 months. And I think that is truly impressive. One year of adjuvant therapy with nivolumab continues to show a sustained disease-free survival benefit over a period of three years in both the ITT and the PD-L1-high patient population. In my view, these results reinforce the utility of nivolumab in the adjuvant urothelial carcinoma setting after surgery. And it will be interesting to see how the overall survival pans out in this study.  So, Neeraj, moving on to kidney cancer, what were your key takeaways from these studies on kidney cancer presented in this meeting?  Dr. Neeraj Agarwal: So, there were exciting results presented from multiple studies in this area as well. For example, Abstract 603 presented by Dr. Mauricio Burotto, senior author was, Dr. Toni Choueiri on the three-year follow-up from the phase 2 CheckMate-9ER trial. So, in this trial, patients were randomized one-to-one to nivolumab 240 milligrams every two weeks, plus cabozantinib 40 milligrams daily versus sunitinib 50 milligrams daily for four weeks, and it was a six-week cycle for sunitinib until disease progression or unacceptable toxicity. So this was the design of the phase 3 CheckMate-9ER trial. And after a median follow-up of three years, the benefit of nivolumab plus cabozantinib remained consistent with previous follow-ups. So, as we know, these data have been presented in the past, also published in the New England Journal of Medicine. But this meeting was a clear follow-up of these data.  Notably, the median overall survival of patients treated with cabozantinib plus nivolumab in the ITT population, which included all favorable intermediate and poor IMDC score patients, was significantly improved at 49.5 months compared to 35.5 months in the sunitinib arm. It is so heartening to see that median overall survival breaching the four-year mark in our patients with metastatic RCC in a consistent fashion. We saw similar data with the combination of ipilimumab plus nivolumab recently. And as these trials are maturing, we are probably going to see more combinations breaching this four-year mark. So importantly, no new safety signals emerged with the additional follow-up in either arm. And I think these results provide further support for the use of cabozantinib plus nivolumab as a first-line treatment option for patients with metastatic or advanced renal cell carcinoma. Dr. Christian Kollmannsberger: Indeed, I think it is extremely impressive what we've seen over the last 15 years in metastatic kidney cancer, going from a median overall survival of about a year to now more than four years. I think that is a great achievement, and we can see it on a daily basis in our clinical practice.  Now, before we wrap up, I would like to highlight another potentially practice-changing trial, LBA602, which titled, “Results from Phase 3 Study of 89Zr-DFO-Girentuximab for PET/CT Imaging of Clear Cell Renal Cell Carcinoma: The ZIRCON Trial” presented by Dr. Brian Shuch. The background of this is that the detection of renal masses poses a challenge due to the limitations of diagnostic options such as imaging and biopsy. And we often, in clinical practice, are confronted with "What exactly is this?" And what's even more importantly, “What's the histology of this?” And a non-invasive, accurate method is needed for pre-treatment risk stratification. Girentuximab, a monoclonal antibody that targets carbonic anhydrase IX expressed on clear cell renal cell carcinoma, can obviously now aid in the differentiation between clear cell renal cell carcinomas and other renal lesions when radiolabeled with this new agent.  The ZIRCON trial was open-label and designed to include patients with renal masses up to 7 cm in size or clear tumor stage cT1 who were scheduled for partial nephrectomy within 90 days of planned TLX250-CDx administration. The enrolled patients received a single intravenous dose of girentuximab on day 0 and underwent FDG PET/CT imaging on day 5 before their scheduled surgery. And the co-primary endpoints were to assess the sensitivity and specificity of girentuximab PET/CT imaging for detecting clear cell renal cell carcinoma in patients with indeterminate renal masses, with histology as the reference standard, which I think is a great way to test these agents because you get 100% validation.  In the primary analysis of 284 patients, the average sensitivity and specificity across all three central readers were 86% and 87%, respectively, exceeding the prespecified thresholds. The positive and negative predictive values were 93.4% and 78%, respectively. And with very few related adverse events reported, the study affirms that girentuximab PET/CT is safe and effective in identifying clear cell renal cell carcinoma in patients with indeterminate renal masses. And the findings hold potential for developing optimal management strategies for patients with indeterminate renal masses. I think this is important that we add a non-invasive method to this because we are confronted on a regular basis with patients who either cannot tolerate a biopsy or where the biopsy is indeterminate. And this could potentially be a great tool to help us with our pre-treatment planning of our treatment strategy. Dr. Neeraj Agarwal: Wow. So, it looks like a new PET scan using a unique tracer and antibody to detect the clear cell renal cell carcinoma with high specificity and sensitivity. It reminds me of drawing a crude analogy from the PSMA PET scan in prostate cancer. And hopefully, we will be able to use these newer scans that we call TLX250-CDx PET/CT scan. I hope they have a simpler name for this very soon. Or maybe follow up for patients who had kidney cancer, localized kidney cancer taken out by radical surgery, and then we are following them. And sometimes, we don't know if a small lung nodule is metastatic or not. And these kinds of imaging studies may help us down the line in monitoring those patients as well. So indeed, very exciting progress not only in the therapeutic area now but also in diagnostic fields at this GU ASCO.   So with that, we have seen multiple abstracts on prostate, bladder, and kidney cancer with real impact on how we practice medicine.

Guest host Dr. Neeraj Agarwal and Dr. Jeanny Aragon-Ching discuss several crucial studies that will be presented at the 2023 ASCO Genitourinary Cancers Symposium, including ARASENS, TRITON3, and others in prostate cancer, as well as novel therapies in mRCC and urothelial carcinoma. TRANSCRIPT Dr. Neeraj Agarwal: Hello, and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, your guest host of the ASCO Daily News Podcast today. I'm the director of the Genitourinary Oncology Program, a professor of medicine at the University of Utah Huntsman Cancer Institute, and editor-in-chief of the ASCO Daily News. I'm delighted to welcome Dr. Jeanny Aragon-Ching, a medical oncologist and the clinical program director of the Genitourinary Cancers Program at the Inova Schar Cancer Institute in Virginia.   Today we will be discussing key abstracts in genitourinary oncology that will be featured at the 2023 ASCO Genitourinary Cancers Symposium.   Our full disclosures are available in the show notes, and disclosures for all guests on the podcast can be found on our transcripts at asco.org/podcasts. Jeanny, it is great to have you on the podcast today.   Dr. Jeanny Aragon-Ching: Thank you so much, Dr. Agarwal, for having me.  Dr. Neeraj Agarwal: So Jeanny, let's begin with Abstract 15 on the update on the ARASENS trial, which Dr. Maha Hussain will present [at the meeting]. In March ‘22, as we know, almost a year ago, the results of the ARASENS trials were published in the New England Journal of Medicine. Darolutamide, which is an AR signaling inhibitor plus androgen deprivation therapy plus docetaxel chemotherapy, significantly reduced the risk of death by 32.5% versus placebo plus ADT plus docetaxel. The effect of triplet therapy, including darolutamide on overall survival, was consistent across prespecified subgroups. However, survival outcomes by disease volume were not reported at the time. Can you please tell us about Abstract 15?  Dr. Jeanny Aragon-Ching: Yeah, thank you so much, Neeraj, I would be happy to. So, this new data is actually very crucial for all clinicians. The title of this abstract is “Efficacy and Safety of Darolutamide in Combination with ADT and Docetaxel by Disease Volume and Disease Risk in the Phase 3 ARASENS Study.” So, as a quick reminder, in this trial, patients were randomized 1:1 to the standard dose of darolutamide 600 milligrams twice daily or placebo with ADT and docetaxel in the metastatic hormone-sensitive prostate cancer setting.    Now remember, too, high volume disease was defined per the charted criteria, which is visceral metastases and/or four or more bone lesions, of which at least one or more has to be beyond the vertebral column or pelvis. 8And high-risk disease was actually defined per the LATITUDE criteria, which is any two or more of the following three factors: Gleason scores eight or more, bone lesions that are three or more, and the presence of measurable visceral metastases. Of all the 1,305 patients, 77% of them were actually classified as having high-volume disease, and 70% of them had high-risk disease. So, in both of these high-volume and low-volume disease patients, the triplet therapy darolutamide, ADT, and docetaxel actually improved overall survival and hazard ratio was 0.69 and 0.68, respectively. Compared to the placebo and ADT, and docetaxel arm. So overall survival improvement was also significant in patients across all risk, high-risk, or low-risk disease.   Dr. Neeraj Agarwal: So, Jeanny, this is great news. So, the main message from this abstract for our audience is that triplet therapy of darolutamide plus docetaxel plus ADT is more efficacious than the doublet of ADT plus docetaxel chemotherapy, regardless of disease volume or risk status.   One important caveat I would like to note is that triplet therapy with the darolutamide was not compared with the doublet therapy of ADT plus darolutamide or any androgen receptor signaling inhibitor such as abiraterone or apalutamide or enzalutamide, all of which have shown benefit consistently, regardless of volume status, and in the case of abiraterone, also in the context of high-risk disease setting, as we saw in the LATITUDE trial.  Dr. Jeanny Aragon-Ching: Absolutely. I agree with that, Neeraj. Those are important points to consider.   Now, moving on to a different setting in prostate cancer across the disease continuum, let's discuss Abstract 18, titled “Rucaparib for Metastatic Castrate-Resistant Prostate Cancer.” This is TRITON3 entering overall survival and efficacy of rucaparib versus docetaxel or second-generation engine pathway inhibitor therapy, which will provide us with some additional data regarding overall survival. Neeraj, based on this new abstract, can you tell us more about TRITON3, which will be presented by Dr. Alan Bryce and colleagues from the Mayo Clinic Arizona?  Dr. Neeraj Agarwal: Of course. So TRITON3 is a randomized multicenter open-label phase 3 trial where rucaparib was compared with the physician choice of docetaxel chemotherapy or abiraterone or enzalutamide in those patients who had not received chemotherapy in the metastatic castration-resistant prostate cancer setting, and they had to be progressing on a prior androgen receptor signaling inhibitor in any setting prior. So, they just had to have disease progression either in the hormone-sensitive setting or CRPC setting on one of the AR inhibitors, and they had to have a BRCA1, BRCA2, or ATM alteration.   So, in this context, these patients were randomized to rucaparib versus physician's choice of agent, which could again be docetaxel chemotherapy, abiraterone, or enzalutamide. So, OS maturity is 54% in BRCA group and 59% in the intention to treat population. In BRCA1 and BRCA2 populations, radiographic PFS, which was the primary endpoint, was 11.2 months in rucaparib group and 6.4 months in the physician choice arm. In the intention to treat population where you include all patients BRCA plus ATM patients, ATM positive patients. Radiographic PFS was 10 months almost versus 6.4 months with standard of care. And both were statistically significant as well as clinically meaningful improvement in the radiographic progression-free survival with rucaparib over physician's choice of either docetaxel or enzalutamide, or abiraterone. I would like to note that most frequent toxicity which we see with this group of agents is most frequent grade III or more toxicity was anemia, which was present in approximately 24% patients treated with rucaparib.  Dr. Jeanny Aragon-Ching: Yeah. This is a really exciting update, Neeraj. What do you think is the key takeaway from this abstract?  Dr. Neeraj Agarwal: The key takeaway is that TRITON3 trial met its primary endpoint, and rucaparib significantly improves radiographic progression-free survival in BRCA mutation-positive patients or BRCA ATM-positive patients. Overall survival is still immature, and these results further establish rucaparib as one of the standard of care options in those patients who have metastatic CRPC with prior treatment with the AR signaling inhibitor and who harbor one of the BRCA mutations or BRCA NAT mutations.   So, Jeanny, before moving on to the renal cell carcinoma section in this podcast, there is an Abstract in prostate cancer talking about correlation between the source of funding and disparities among patients with advanced prostate cancer. So, I'm referring to that Abstract 40, titled “Source of Funding and Enrollment Disparity in Prostate Cancer Clinical Trials.” I thought this was an interesting abstract. Could you please tell us more about this abstract?  Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. So, in Abstract 40, Dr. Riaz and Dr. Bryce, and colleagues actually looked at phase II and III clinical trials that involved prostate cancer patients that reported on patients with age by 65 years, and they got the data from the MEDLINE and Embase databases. Trials recruiting from the United States were considered eligible for analysis by race and ethnicity. So, in terms of race and ethnic enrollment, they found that black patients were significantly underrepresented in the industry's funded trials. Notably, no significant disparity was observed in the US government-funded trials, but Hispanics were also significantly underrepresented in industry-funded clinical trials. However, no significant disparity was seen in terms of older adults overall and by funding sources. Remarkably, Black patients' representation in industry-funded prostate cancer trials has actually decreased over the last three decades.  Dr. Neeraj Agarwal: That's concerning. So, what is your key takeaway from this trial, Jeanny?  Dr. Jeanny Aragon-Ching: The key message here is that Black and Hispanic men with prostate cancer are significantly less likely to be included in industry-sponsored clinical trials. A bigger concern is that black patients' representation actually continues to decline over time. So these results warrant a really more proactive role by regulatory bodies to ensure that a proportional representation of minorities in the industry trials, which in turn will make these results more applicable to a wider entire population of men with prostate cancer.  Dr. Neeraj Agarwal: Thanks, Jeanny. Let's move on to renal cell carcinoma. I saw some innovative research correlating the efficacy of immune checkpoint inhibitors with the time of the day these checkpoint inhibitors were administered. So, interestingly, there were two studies from two different groups of investigators showing very similar results. Please tell us about this innovative research correlating outcomes with immune checkpoint inhibitors with the time of the day these medicines or these drugs were infused into the patients.   Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. I think they're very exciting and interesting. So there's actually two abstracts, so Abstract 681 and 678, which we, of course, can discuss separately. So, let's probably start first with Abstract 678. Neeraj, do you want to explain to us further about this abstract?  Dr. Neeraj Agarwal: Yes. When our center participated in that abstract, which was led by Dr. Nazli Dizman from Yale University, Dr. Dizman and colleagues examined the relationship between the time of the administration of immune checkpoint inhibitors, or ICIs, as we call them, during the time of the day, and outcomes in patients with metastatic renal cell carcinoma. So, I'd like to point out that previously Dr. Qian and colleagues reported an association between the time of day of immunotherapy infusion and survival outcomes in patients with metastatic melanoma.   In this study, Dr. Dizman and colleagues, which included our center also, patients with metastatic RCC who received nivolumab with or without ipilimumab– so these patients all received either nivolumab alone or without ipilimumab. And patients who received less than 25% of infusion after 4:30 pm. were assigned to the early-time of infusion group. So, if they have received less than 25% infusion of these immunotherapies after 04:30 pm in the evening, they belong to the early infusion group, and the rest were assigned to the late infusion group.  In the univariate analysis, numerically higher objective responses and time to treatment failure were observed in the early infusion group compared to the late infusion group. So, differences were 33% versus 25% in objective responses in early versus late infusion group. If you look at time to treatment failure, 8.3 months versus 4.4 months in early versus late infusion group. In the multivariate models, which took into account the clinical characteristics such as age, gender, line of treatment, IMDC risk category, histological subtypes, there was a trend towards improved outcomes in those who received these infusions with ICIs early in the day. So, Dr. Dizman concluded that larger randomized and controlled investigations are warranted to examine the impact of this chronal modulation, if you will, on the efficacy of immune checkpoint inhibitors in metastatic RCC sets.  Dr. Jeanny Aragon-Ching: Yeah, this is very interesting data, Neeraj. And that actually resonates closely with this other abstract by Fernandez Manias and colleagues in Abstract 681. So, in this abstract, the primary outcome was overall survival, but they did look at other secondary endpoints like time on treatment, time to the next treatment, and overall response rates. Now, because of the small number of events, the authors actually focused on just patients who received second-line immune checkpoint inhibitors. And what they did was they looked at patients who received overall more than 20% of their infusions after 04:30 pm, and they found that those who did receive actually fewer infusions had a significantly shorter time on treatment and had a worse overall survival. And similar results were seen when they looked at those who got more than 50% of their dose of checkpoint inhibitors that were administered after 04:30 pm, so interestingly enough, there was a 16% increase in the risk of death for each 10% increment of checkpoint infusion after 04:30 pm. So the key message here is that administration of checkpoint inhibitors after 04:30 pm is associated, unfortunately, with inferior outcomes. Now, these results should, of course, be further considered in the organization overall of the outpatient clinic as it can impact patient survival and outcomes.  Dr. Neeraj Agarwal: Very interesting. So similar results from two independent groups of investigators from two different continents obviously made this research area very appealing and pertinent. Ideally, I think these results should be validated prospectively, but that will take time. But investigators who have already lagged multiple phase III trials should explore validating these results in the last phase 3 trials which have already been reported and where the data on the timing of infusion is available. Once validated, I think these results may profoundly influence how we organize, as you said, Jeanny, the outpatient scheduling of these checkpoint therapy infusions compared to those who are not checkpoint inhibitors. I think this is going to have very interesting data overall, no doubt.   Before moving onto bladder cancer, I would like to discuss an important abstract related to testicular cancer patients titled “Longitudinal Evaluation of Plasma MicroRNA-371 to Detect Minimal Residual Disease and Early Relapse of Germ Cell Tumors.” Could you please tell us more about this abstract?  Dr. Jeanny Aragon-Ching: Yeah, absolutely, Neeraj. So this is a very interesting up-and-coming Abstract, it's number 407, which will be presented by Dr. Lucia Nappi and colleagues. In this study, clinical patients with stage I germ cell tumor with available plasma samples after they underwent radical orchiectomy were all included. So, they looked at sensitivity, specificity, negative, positive predictive values, an area under the curve in predicting tumor recurrence, and they evaluated the microRNA-371, I'll just call it and truncate it as miR-371, and compared the same operating characteristics of current gold standard diagnostic tests. Relapse-free survival was correlated to post-orchiectomy miR-371 status, which could be either positive or negative.   So, at a median follow-up of 41 months, 101 patients with clinical stage one germ cell tumor were included. About 35% of them experienced a disease relapse during that time of follow-up. Now, what they found was miR-371 was positive in about 63% of the relapsed patients, and the miR-371 positivity preceded clinically evident disease by a median of about three months. The specificity and positive predictive values were 100%, sensitivity was like 63%, and negative predictive value was 83.5%, so very high. No false positive results were seen. And, the authors reported that the recurrence-free survival of the patients who had positive post-orchiectomy miR-371 was significantly shorter compared to those patients who had a negative biomarker for the miR-371. So, they concluded that the miR-371 sensitivity correlated with the tumor burden, time between tumor relapse, the microRNA testing, and histology. It was notably a little bit more sensitive in non-seminomas compared to those who had seminoma.  Dr. Neeraj Agarwal: Interesting findings, indeed. So, Jeanny, what is the take-home message from this abstract?   Dr. Jeanny Aragon-Ching: Yeah, so I think the key takeaway is that microRNA-371 seems to be a good test, like a biomarker for predicting disease relapse in patients with early-stage germ cell tumor. So, additionally, its high specificity and positive predictive value in predicting relapse could really be used and utilized to guide adjuvant therapy, selections, and decisions after orchiectomy. Further validation in other studies, such as swab 1823, are currently ongoing or planned to validate its clinical utility.   So Neeraj, moving on to bladder cancer, the last abstract I'd like to mention before we wrap up the podcast is Abstract 563, titled “Utility of ctDNA in Predicting Outcome and Pathological Complete Response in Patients with Bladder Cancer as a Guide for Selective Bladder Preservation Strategies.” Neeraj, can you tell us more about this abstract?  Dr. Neeraj Agarwal: Sure. So, this study was led by Dr. Lars Dyrskjøt. He and colleagues evaluated the prognostic value of circulating tumor DNA, or ctDNA, in predicting recurrence in a cohort of 68 patients with muscle-invasive bladder cancer who received new adjuvant chemotherapy prior to cystectomy. So ctDNA was analyzed two times at baseline before new adjuvant chemotherapy and then before surgery or before cystectomy. So, patients had ctDNA assessed before neoadjuvant chemotherapy and then before cystectomy after completion of new adjuvant chemotherapy. At baseline, of the 64 patients, around 60% were ctDNA negative, and 40% were positive for ctDNA. So of those patients who were ctDNA negative, 84% achieved pathologic complete response, while in those who tested ctDNA positive, only 35% achieved their pathologic complete response after surgery.   Prior to surgery, 84% of patients were ctDNA negative, and 81% achieved pathologic complete response. While none of the ctDNA-positive patients who were positive before surgery and after neoadjuvant chemotherapy, none of them achieved pathologic complete response, which translates into a positive predictive value of 100% and a negative predictive value of 81% for this test. So based on both ctDNA time points, the probability of ctDNA negative patients to achieve a pathologic complete response was significantly higher than ctDNA positive patients.   At a median follow-up of 59 months, ctDNA-positive patients without pathologic complete response demonstrated significantly lower recurrence-free survival and overall survival compared to those who were ctDNA negative. So, I want to repeat that, at a longer follow-up, which Dr. Dyrskjøt will be presenting, ctDNA positive patients without pathologic complete response had significantly lower recurrence-free survival and overall survival compared to ctDNA negative patients. Furthermore, ctDNA status at baseline, which is before neoadjuvant chemotherapy and before cystectomy, was a better predictor of recurrence-free survival compared to pathologic complete response, which is a remarkable finding here, although it's a smaller data set.  Dr. Jeanny Aragon-Ching: Agree completely, Neeraj. So, I think the importance here, too, is upon prospective validation in larger data sets, we will find that a negative ctDNA test would help in identifying patients who can benefit more from bladder-sparing strategies.   Neeraj, any final thoughts before we wrap up the podcast today?  Dr. Neeraj Agarwal: Before I share my final thoughts, Jeanny, I would like to thank you for joining us and sharing your insights.

JCO PO author Dr. Shilpa Gupta, MD, Associate Professor of Medicine at the Cleveland Clinic and GU Medical Oncology Director, shares analysis on outcomes in real-world settings for metastatic urothelial carcinoma (mUC) patients. Host Dr. Rafeh Naqash and Dr. Gupta discuss the utility of tumor mutational burden (TMB) to determine treatment, and mUC patient response from immune checkpoint inhibitors (ICPI) as compared with carboplatin. Click here to read the article!   TRANSCRIPT Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations. I am Dr. Rafeh Naqash, assistant professor of medicine at OU Stephenson Cancer Center. You're listening to the JCO Precision Oncology Conversations podcast.   Today I'll be talking with Dr. Shilpa Gupta, who is an associate professor of medicine at the Cleveland Clinic and also the GU Medical Oncology Director. And we'll be talking about their group's recent paper, ‘Tumor Mutational Burden as a Predictor of First-Line Immune Checkpoint Inhibitor Versus Carboplatin Benefit in Cisplatin-Unfit Patients With Urothelial Carcinoma'.   Full disclosures for our guest can be found on the article's publication page.   Hello and welcome to the podcast, Dr. Gupta. It's nice to have you here. For the sake of this podcast, we'll be referring to each other using our first names. So welcome and thanks for joining us today.   Dr. Shilpa Gupta: It's my pleasure to be here, Rafeh, I'm really excited about chatting about this paper with you. Thank you for the opportunity.   Dr. Rafeh Naqash: Thank you so much. So today we'll be discussing this interesting publication of yours, talking about biomarkers. And I often refer to biomarkers as the Pandora's Box for immune checkpoint inhibitors because definitely one size does not fit all. And reading through your paper, I saw a lot of interesting findings that you have defined in this publication. But for starters, what was the premise and background of why you wanted to study this question of tumor mutational burden as a biomarker in this patient population?   Dr. Shilpa Gupta: Yeah, that's a great question, Rafeh. The treatment paradigm for urothelial cancer patients has really evolved over the last many years. For example, patients who are eligible to receive cisplatin-based chemotherapy, that's the treatment of choice. And for patients who are not eligible to receive cisplatin due to a variety of reasons like chronic kidney disease, heart failure, peripheral neuropathy, poor performance status, or hearing loss, in the past, we used to treat them with gemcitabine and carboplatin, but outcomes were quite dismal with median overall survival less than six months or so. And then in 2017, the approval of pembrolizumab and atezolizumab as single agents was welcome news because these patients had more durable responses and survival was longer than historically with gemcitabine-carboplatin. And this is what became the standard of care based on the FDA expedited approval.   However, in 2018, the FDA restricted the use of immunotherapy only to those patients whose tumors had high PD-L1 or who were not eligible to receive carboplatin, based on the interim analysis from the phase three trials IMvigor130, which compared atezolizumab to gemcitabine-carboplatin, one of the cohorts for cis-ineligible patients, and KEYNOTE-361, which compared pembrolizumab to gemcitabine-carboplatin in the cis-ineligible cohort. And furthermore, recently, the FDA actually further restricted the label for pembrolizumab, because in the phase 3 study, even in high PD-L1 subgroups, pembrolizumab did worse than gemcitabine-carboplatin, regardless of their PD-L1 status. There were early deaths, lower response rates, and in the IMvigor130 study, we recently saw that atezolizumab was actually withdrawn for this indication altogether.   So there has been this attraction for PD-L1 for a long time, but now multiple studies in urothelial cancer have shown that PD-L1 is not a durable biomarker. And we wanted to see if there's other biomarkers which can be accessible at the point of care. And we wanted to study how tumor mutational burden can or cannot pan out as a treatment selection or complementary to clinical criteria. Right now, there's no biomarkers to guide treatment for patients in urothelial cancer for carboplatin or immunotherapy use. And that was the premise for the study.   Dr. Rafeh Naqash: Excellent. Thank you so much for that detailed understanding of why you decided to pursue this.   Now, from the listener standpoint when you define cisplatin-ineligible patients, in your practice, what is the percentage of patients that you see who are technically cisplatin-ineligible? Does comorbidity play an important role in determining which patients, or does it depend on your discussion with the patient? What are those factors that you would describe to define what cisplatin-ineligibility would constitute?   Dr. Shilpa Gupta: So historically, Matt Galsky and colleagues described cisplatin-ineligibility as patients with a creatinine clearance less than 60 mLs per minute, hearing loss greater than grade two, poor ECOG performance status two or higher, peripheral neuropathy, which is significant or significant heart failure. Now, those all make patients ineligible for cisplatin. Now, more recently, we know that we can safely give cisplatin as long as creatinine clearance is above 50. So for the real world, 50 is a threshold where we can use split dose cisplatin. And I'll say, given that bladder cancer or urothelial cancer is a disease of the elderly, median age being 71 years, a lot of our patients have these comorbidities, chronic kidney disease, diabetes, and whatnot, which precludes us from using cisplatin. So in the real world, I would say that around 50% of patients are ineligible to receive cisplatin.   Dr. Rafeh Naqash: Interesting. And that goes back to the point where not everything that resulted from clinical trials, or the data that we get, may not be exactly applicable to the real world patient population, as you have pointed out in this interesting paper. So going back to the manuscript now from a methodology perspective, what kind of data did you include to get to the results that we'll talk about next? What was the inclusion and what was the patient population in this analysis?   Dr. Shilpa Gupta: So the patient population basically were patients who had a confirmed diagnosis of metastatic urothelial cancer. And the databases we used were the US-wide Flatiron Foundation Medicine Clinical Genomic Database, which has patients who were listed as metastatic urothelial cancer. But in addition, they also had genomic testing performed from their tumors, and results were available. And we accessed the database between 2011 until April 2021. And all these patients had had genomic testing using Foundation Medicine assay. And this de-identified data was basically US-wide across 280 cancer clinics and that's around 800 sites of care. And there's a whole range of retrospective longitudinal clinical data that was available, derived from the electronic health records comprising patient-level structured and unstructured data and also their genomic information from the tumors. And there was clinical data including demographics, lab values, performance status, timing of treatment, exposure, as well as time of progression and survival.   We decided to include patients if they received a frontline single agent immunotherapy, no matter what it was, whether pembrolizumab, atezolizumab, Nivolumab, durvalumab or avelumab, or a carboplatin-based chemotherapy. And just for the readers, this is a retrospective review. So we just used these selected patients who got in these therapies. We also required that these patients had tumor mutational burden information available through the tissue biopsy and patients who received chemotherapy and immunotherapy together were excluded and details are present in the manuscript, but this was pretty much the broad selection criteria.   Dr. Rafeh Naqash: Thank you so much. And definitely a very representative patient population from a real world setting with different therapy and different other clinical variables that are relevant in the real world setting.   So from an analysis standpoint, you, from what I read, define both a predictive and a prognostic aspect to tumor mutational burden. Could you tell us more about those results and highlight some of the interesting findings from that perspective?   Dr. Shilpa Gupta: Yes, absolutely. So as you know, tumor mutation burden cut off of ten mutations per megabase is currently utilized by the FDA, whereby approval of pembrolizumab for tumor agnostic condition was made. So that's what we considered high versus low. And we found that in this, after propensity weighing in, the tumor mutational burden less than ten group, basically those patients did not benefit from checkpoint inhibitor single agent as compared to tumor mutational burden of ten or greater. And so basically, we found that patients who had tumor mutational burden ten or higher overall had more favorable progression-free survival time to next treatment, as well as overall survival when they got a single agent immune checkpoint inhibitor, as opposed to those who got carboplatin, and also when compared to those who had tumor mutational burden less than ten. So we also looked at PD-L1 information available from the genomic database, but it was only available for around 35% of patients and still we were able to see that PD-L1 did not correlate with any of these outcomes as we show in the paper.   Dr. Rafeh Naqash: I see. And as you mentioned, you show both time to treatment failure PFS being better in TMB high patients defined as ten mutations per megabase. I didn't specifically see results related to TMB high versus low in a carboplatin specific cohort. Is that analysis something that was looked at and trying to understand whether neoantigens in a platinum-based setting specifically make a difference whether high TMB is predictive there in the carboplatin setting. Was that looked at?   Dr. Shilpa Gupta: So yes, we looked at, in the Figure 4, for the comparison of the TMB and which we were looking at the checkpoint inhibitor versus chemo. So for TMB low the chemotherapy cohort had more favorable results. Is this what you were getting at?   Dr. Rafeh Naqash: Yeah, I think what I was specifically trying to look at, like you have shown in the paper, is TMB is predictive of benefit with checkpoint inhibitors and is also prognostic in the checkpoint inhibitor setting. So my question was more whether it had a prognostic implication in a carboplatin specific cohort. So meaning high TMB, whether it correlated with better outcomes with carboplatin therapy versus low TMB. So if that was looked at.   Dr. Shilpa Gupta: We didn't look at that specifically, we only compared whether high TMB did better with the immunotherapy or chemotherapy.   Dr. Rafeh Naqash: And some of the correlation of this in my mind comes from some data that people have looked at in the lung cancer setting, whether high TMB makes a difference and for example, resected lung cancer patients, which usually gets platinum-based adjuvant therapies. So that's why I was wondering if there's any correlation there. But this is definitely interesting.   Now, my next question was going to be in your manuscript you mentioned around 30% of patients had tumor mutational burden more than or equal to ten. Did you identify any other unique characteristics from any other mutational standpoint or a PD-L1 standpoint in the high TMB cohort?   Dr. Shilpa Gupta: Yes. So PD-L1 didn't really stand out to be a very steady biomarker in our experience. And this is also what was reflected in the phase three trials like DANUBE where they looked at the durvalumab and tremelimumab, IMvigor130 or KEYNOTE-361. So that was pretty consistent that these studies also showed TMB to be more useful in exploratory analysis. Of course, these patients were not stratified based on that. And we also looked at other emerging biomarkers, for example, F-TBRS and angiogenesis gene expression signatures as well as tGE3. And we need to evaluate them in a separate study to see what pans out.   But for now, I think as far as in the real world, we are looking at a lot of genomic testing being done and right now we really don't know how to use that for making treatment decisions, right? PD-L1 has really phased out as of any utility whatsoever. And using TMB; I think in addition to the clinical characteristics, like when possible, we should be offering patients carboplatin. There's no doubt about that for cisplatin ineligible patients. But there's those patients who, if they're refusing chemotherapy and we really can't make a case for giving them single agent immunotherapy, I think TMB can come in handy to justify and make sure that we're not doing them a disservice by not giving carboplatin. And I think future trials need to use this biomarker in a prospective setting to further establish its utility.   Dr. Rafeh Naqash: Definitely, I agree it's a case-by-case situation from a patient standpoint to determine what therapy is appropriate for the patient and what is most realistic, what is the expectation that the patient has, from that treatment.   Now, from a TMB standpoint, one of the ongoing debates is if it is a binary cut off or whether it could be tertiles for a certain tumor type or quartiles. Was there any subanalysis or any subsequent study that your team would be looking at from a TMB cut off standpoint? Maybe a higher cut off would mean a better outcome and maybe lesser duration of therapy in those patients. Is that somewhat of a consideration?   Dr. Shilpa Gupta: Yeah, that's a great question, Rafeh. And I think the reason we stuck to it as a binary end point is because that's the FDA definition, so people don't try to extrapolate based on anything higher or lower. But yeah, that's a great question. And I know in lung cancer they're looking at different ranges. As far as urothelial cancer, we just stuck to the ten mutations per megabase for now.   Dr. Rafeh Naqash: Of course. And one of the other interesting things I really like to see in the paper is your figure specifically on the ECOG performance status and how clinical trials sometimes do not include patients on the higher ECOG performance status spectrum. And your study obviously had a good representation on that standpoint. What were some of the findings from the ECOG standpoint that were somewhat different in your cohort than what you would see in clinical trials in general?   Dr. Shilpa Gupta: Yes, as we've shown in Figure 5, the ECOG in real world, it was quite an eye opener to see that there was a considerable number of patients who were documented as ECOG performance status three. And if you see the ECOG performance status two bar was around 50% and ECOG performance status one was also lower than what has traditionally been included in the phase three trials. And in the phase three trials, there's hardly any patients with ECOG performance status two compared to what we saw in the real world. And very few patients, in fact, hardly any had ECOG performance status zero in our real world analysis. So clearly the trials need to be more inclusive, as has been the ASCO message all along. And it's always very surprising to see the big gap between the real world and the clinical trial patient population.   Dr. Rafeh Naqash: Definitely, I think more and more, especially cooperative group trials that you and many others are leading, are trying to be as inclusive as possible, which is important to get a better understanding of how these therapies do in different patient populations. And one of the questions I wanted to ask you, and I've seen this a few times in different checkpoint therapy treated tumors, is this initial rapid progression in some patients where the chemotherapy arm does better, but the immunotherapy arm kind of falls rapidly and then starts plateauing. In your clinical experience, have you seen that? And if yes, what are the features of some of those patients that have this rapid progression from a clinical and both from a biomarker standpoint?   Dr. Shilpa Gupta: That's a great question, Rafeh, and we do see that every now and then, and especially in my experience, we've seen that in women in particular who have bone metastases are really challenging to treat with immunotherapy. And sometimes we find that the disease just rapidly blows through immunotherapy and we really need to do more biomarker work to understand what determines these biomarkers of hyper-progression, so to speak. I know there's a lot of work going on in the field and we are also trying to understand these by serially collecting blood and circulating tumor DNA from our patients during their treatment journey.   Dr. Rafeh Naqash: Exactly. Definitely work in progress and another unique patient population where more needs to be done to understand what are the events that lead to these hyper-progression aspects, whether it's in the bone or brain or any other compartment in the body.   Well, this has been exciting and interesting, but before we end, we try to know a little bit more about the investigator, the author. So, Shilpa, can you tell us a little bit about your journey in oncology and your journey as a trainee, your journey as faculty, as a clinical trialist, as a successful clinical trialist? And any advice for junior investigators listening to this conversation?   Dr. Shilpa Gupta: Yeah, thank you for asking. I think oncology always struck me as a very exciting field back in my residency days, 2005, 2006. And at the time, so much was going on, like just drugs like bevasizumab were just coming around for colorectal cancer and in lung cancer drugs like EGFR inhibitors were coming around. And that kind of really excited me. And talking with my mentor at the time, who was a really well-renowned transplanter, he said to me that if he had to do it all over again, he would love to get into solid tumor oncology with all the excitement that's going on. I was drawn to oncology also because of, not only it's a learning experience every day, but it can be very gratifying to see amazing responses and patients living longer despite having advanced disease, and also provides a lot of challenges every day when every patient is not the same. So I think that was the reason why I was drawn to oncology and provides us an opportunity to really develop new therapies as opposed to some of the other specialties because of how challenging the patient population is.   And as far as my journey, you know, I've now been in the US for almost 18 years and have been in a variety of places, and I think it's been a very rewarding journey despite multiple bumps along the way. And I'm really glad to be doing what I'm doing and trying to advance the field, clinical trials, and learning from people around me.   Dr. Rafeh Naqash: Thank you so much for giving us a little glimpse into your journey and your experiences. And it's always inspiring to listen to successful investigators and also try to emulate in some ways what you have done and what you've achieved. And thank you again for coming on this podcast. And thank you for choosing JCO Precision Oncology as a destination for your manuscript, and hopefully we'll see more of the same from you and your group in the subsequent years to come and more in this field of biomarkers.   Thank you for listening to JCO Precision Oncology Conversations.

Dr. Charles Ryan, president and CEO of the Prostate Cancer Foundation (PCF), joins ASCO Daily News Editor-in-Chief Dr. Neeraj Agarwal, of the University of Utah Huntsman Cancer Institute, to assess impactful prostate cancer research from the PCF's recent conference and discuss Dr. Ryan's vision for the future, including increasing access to cutting-edge care. TRANSCRIPT Dr. Neeraj Agarwal: Welcome, to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, the editor-in-chief of the ASCO Daily News, and director of the Genitourinary Cancers Program at the University of Utah Huntsman Cancer Institute. Today, we'll be discussing compelling research that was featured at the recent Prostate Cancer Foundation Scientific Retreat, and I'm very pleased to welcome Dr. Charles Ryan, the president, and CEO of the Prostate Cancer Foundation. Our full disclosures are available on the transcript of this episode, and disclosures relating to all episodes of the ASCO Daily News Podcast are available on our transcripts at: asco.org/podcasts. Dr. Ryan, thank you for taking the time to be with us today. Dr. Charles Ryan: Dr. Agarwal, thank you. It's my pleasure to be with you. Dr. Neeraj Agarwal: So, Dr. Ryan, before I discuss the PCF meeting, I would like to ask you, what made you move to the PCF as the president and CEO when you had a flourishing career as a division chief of a large academic program, and as one of the top and internationally recognized investigators in prostate cancer? Dr. Charles Ryan: Well, thanks. That's a fair question, I guess. And it took me about three minutes to make the decision when I was offered the position, simply because the Prostate Cancer Foundation has been one of my intellectual homes for my entire career. I've been at the University of Wisconsin, Memorial Sloan Kettering Cancer Center, UCSF, and the University of Minnesota, and all those institutions were affected by the Prostate Cancer Foundation, or previously, CaP CURE. So, I was involved in their research during my time at all those institutions. In addition to my own personal legacy with the PCF, but more importantly, is the fact that it is an organization that funds the deepest scientific inquiry into prostate cancer and the ways that it can cause suffering and death for men with the disease and has made tremendous progress in identifying factors that lead to that lethality. It's also a community of scholars, a community of researchers, that is a platform really for collaboration. And it's also an organization with a world reach - we fund research in 28 countries around the world, and we fund research going from the scope of very basic research to correlative research, to quality of life, and health services research. Dr. Neeraj Agarwal: That is truly impressive and inspiring. So, what is the mission of the Prostate Cancer Foundation formally? Dr. Charles Ryan: Formally, it's pretty simple. The mission of the Prostate Cancer Foundation is to reduce the death and suffering from prostate cancer. Dr. Neeraj Agarwal: So, the 29th PCF Scientific Retreat was recently held on October 27 to October 29th in Carlsbad, California. What were the goals and objectives of this meeting? Dr. Charles Ryan: The meeting, we call it the retreat, it's an annual event and it always has several goals. One is, it's where we announce and hand out, if you will, our awardees of our various awards that we give. It's also a reporting-in process where those who have been using PCF funding are called to come and discuss their work. We also want it to be an open forum for individuals to come and interact - it's really a collaboration and an interaction vehicle as much as anything. So, when you come to our scientific retreat, we all stay at the same hotel, we all share meals together, nobody goes out for dinner. You don't leave the campus, essentially, of the hotel where we are. We have many, many round tables set out, it's designed to be interactive. We have a big room where people are giving their talks, but if you step outside of the room, there are likely to be many, many conversations happening, and those conversations range from collaborations being formed to people looking for jobs, to people getting advice and mentoring, and even people sharing, as I've done over the years, compelling and challenging patient stories around prostate cancer, and really engaging in what communities do - which is, share ideals, share a mission, and share a passion for what they do. Dr. Neeraj Agarwal: Very interesting. Very inspiring. Please tell us some of the highlights of the meeting. Dr. Charles Ryan: Sure. Well, there are many highlights. There are many things happening in prostate cancer research. Most notably, there are a number of papers and investigators that are looking at how prostate cancer evolves, and probably the most significant set of observations that have been made in the field in the last decade, have been understanding the diverse and numerous mechanisms that underlie the evolution of prostate cancer from a disease that responds to hormonal manipulation, to one that becomes resistant to hormonal manipulation. And so, a lot of the work that's happening now is identifying, for example, the evolution of neuroendocrine prostate cancer, or mixed types of prostate cancer, or this sort of evolution of it under constant therapy. And that is allowing the exposure of new targets that we can exploit for new therapy development, and that feeds into some of the grant-making process that's going on in the background. And so, you have a lot of individuals who are looking at this or that mechanism pathway related to disease resistance that they can exploit, and whether they can create small molecules to do that, or antibodies to do that, et cetera. At the same time, we have a strong component of discussion of how prostate cancer affects different populations. So, we had some really nice talks looking at healthcare disparities and different populations across the world, and how they're affected by prostate cancer, and how care delivery may be impacted in those groups of patients. And then you have topics ranging around survivorship and other factors that are looking at what is life like for a man with advanced prostate cancer, which is in many cases, you know, men who get prostate cancer, who have recurrent disease, who end up going on systemic therapy are frequently on the treatment for 5, 10, 15 years. And so, survivorship, and how they live their life, and what the complications are of that treatment, is tremendously important because it's such a daily experience for these men undergoing treatment. Dr. Neeraj Agarwal: So, how does the Prostate Cancer Foundation support and build the next generation of prostate cancer researchers? Dr. Charles Ryan: Right. So, the PCF supports the next generation in a very specific way, in addition to the informal way of bringing people together and inducing collaborations. We have a program called the Young Investigator Program. It started formally in 2008, but before that, there were one-off, if you will, Young Investigator Awards being given. So, our Young Investigator Awardees receive $75,000 per year to support their work, and we awarded 34 of those this year. The range is somewhere from 25 to 34 per year. We get over 100 applications for them every year. It's a straightforward application - they need to have a project that's going to be about three years in length, they need to be mentored, and they are best served by describing a mentorship plan for themselves and how that mentorship relationship will help them grow in their careers. Now, once you become a Young Investigator, it's not that we just write you a check and wish you well, we do that, but we also have annual check-ins. So, we try to visit the sites of our Young Investigators, see them in their home institution, and meet with their colleagues and their mentors. And that's one of the things I do, or Howard Soule does-- Howard Soule, is our chief scientific officer, one of those things we try to do. We also bring them to the scientific retreat that we just had last week, and we have them present their data. So, a vast number of the individuals who are presenting at the scientific retreat are in fact, Young Investigators, or they were Young Investigators when they started the projects that they are presenting. And then, the other thing we do is we have another retreat specifically for the Young Investigators, and that's called the Coffey-Holden Retreat, and that's named after Don Coffey, the late researcher from Johns Hopkins, who is really considered to be one of the grandfathers of prostate cancer research, and Stuart or Skip Holden, who is one of the founders of the Prostate Cancer Foundation, and a urologist at UCLA. So, that event that we do is designed for people to come to give highlights of the work that they're doing; it's designed to be incredibly interactive. In fact, we have 15 or so minutes of presentation, followed by sometimes 25 minutes of questions for each presenter. There's always a line of people who are waiting to ask questions, and it's designed to engage and have that dialogue with the Young Investigators, to make their science better, and to get it known. And so, the Young Investigator Program, it's about 30 individuals per year on average, and the average age is about 30. Many of these are postdoctoral PhDs, and many of them are fellows, or early-stage faculty, MDs. And I like to think that if somebody's going to work until the age of 70, we're stimulating, or launching a 40-year career with these Young Investigator awards. So, I like to think that if we give 25 out, times 40 years, that's 1,000 years of research that we're sort of stimulating with this Young Investigator program. And I bring that up for the reason that we're very proud of the fact that many of our Young Investigators may start out in prostate cancer, and their ideas, their science, takes them elsewhere. And that's what science does. And we, of course, are very, very focused on solving the problem of prostate cancer, and we want people to do that. But we also understand that by launching a scientist, by launching a scientific career, you may end up with people going off in different directions. And so, we have many examples of that. And in my talk this year, I actually highlighted a person who, let's say she won an investigator award when she was young, it was before the formal Young Investigator Award was named, and this was a person who is creating conjugates for the delivery of chemotherapy to prostate cancer cells. And this was Carolyn Bertozzi up at UC Berkeley, and she just won the Nobel Prize. She didn't win the Nobel Prize for research she did on prostate cancer, but at some point, at one point in her career, this was a direction she was going, and she got two grants from us in 1999 and 2000, that helped her work continue on and go the direction that it did. Dr. Neeraj Agarwal: Yeah. And congratulations. Dr. Charles Ryan: Sure. I'll take credit for that one. Dr. Neeraj Agarwal: Being the President and the CEO, you deserve the credit. Dr. Charles Ryan: Sure. That's my job. Dr. Neeraj Agarwal: So, we are coming to the end of the interview, but let me ask you this; the prostate cancer field is so constantly evolving. What is your vision for PCF going forward? Dr. Charles Ryan: Well, my vision for the organization is that we are going to continue on our mission to reduce the death and suffering from prostate cancer. But that's a fairly general statement, and one of the ways you can do that is you can research cancer at a molecular level, and you could try to develop new therapies - we're going to continue to do that. But there's also a real problem, especially, in the United States, and actually globally, with individuals with prostate cancer who are not receiving the cutting-edge care, not receiving the cutting-edge therapy. We have some data that in the United States, maybe upwards of 50% of men with metastatic hormone-sensitive prostate cancer are not getting the therapies that are supported by the latest findings from randomized phase III trials. And this may be for economic reasons, it may be communications or an education deficit with their treating clinicians, and there may be other factors as well. So, as we think about the vision of this, we need to be mindful of that, because if we only focus on studying the cancer molecularly, and we don't address what's happening on the other end, then we're not completing the story, and we're not completing the mission. And so, I've started calling Prostate Cancer Foundation the Global Public Square of Prostate Cancer, because I think of four sides of that square - funding research, as of what we just got done talking about, education and communication, is another one, and we do that in the same way that you are doing this today - through podcasts, and web content, and in-person meetings, as well as applied discovery, which is helping our researchers take their discoveries or their findings out into the clinic. Now, you might think, "Well, that's a small molecule, becoming a company going into a phase I clinical trial." Certainly, that's part of it, but it's also the epidemiologist who is making observations about diet and exercise, who is then empowered to do a clinical trial of exercise and diet intervention. It's also the health services researcher who is able to use their data to go talk to payers or talk to organizations about how care may be delivered differently. So, that's applied discovery. And then finally, supporting the patient is part of what we do. So, we also hold patient webinars every month, we've held patient summits at various points around the country where we bring patients together and talk to them about the latest research or about the factors we've discussed, such as survivorship, or quality of life after treatment, or treatment complications, and things like that. Dr. Neeraj Agarwal: That's wonderful. Thank you so much for sharing your insights. Any final remarks, Dr. Ryan? Dr. Charles Ryan: Dr. Agarwal, thank you so much. It's always a pleasure to speak to another Genitourinary Oncologist, of course, about the field, and the opportunity to talk about the Prostate Cancer Foundation and what we're doing, and the directions we are trying to grow. We've had a great collaboration with ASCO over the years, and I hope that that continues as well. I hope anybody who is interested would come and visit us at: pcf.org, and they can also check us out on: urotoday.com, where we have a lot of content that might be of interest to them.

For this Throwback Thursday, just after Father's Day, I knew I wanted to bring you this episode with my friend, an incredible father and podcaster at the While Black Podcast, Darius Hicks.    This past week in the United States, in addition to Father's Day, we also acknowledged Juneteenth (short for “June Nineteenth”) an annual commemoration of the effective end of slavery in the United States after the Civil War. It came when federal troops arrived in Galveston, Texas in 1865 to ensure all those enslaved were freed, a full two and a half years after the signing of the Emancipation Proclamation. It's considered the longest-running African American holiday and last year in 2021 became a federal holiday.    For those of us who are not Black, Juneteenth is an opportunity to learn more about the history of slavery, to reflect on how much more is needed for Black people to be truly free in this country, and to recommit to antiracism.    Just over a month since a white gunman killed 10 Black people at a supermarket in Buffalo, one of the deadliest racist massacres in recent U.S. history, this conversation with Darius is a necessary call to action to learn more and identify how we can be part of the change that is needed.    Darius gifted us with exceptional insight, perspective, and vulnerability in this conversation. I'm honored to share it with you again.   So join us in this episode as we celebrate amazing fathers all over the world!   About Darius:   Darius has always displayed an entrepreneurial and activist spirit. Since his youth, he has dedicated his time to those around him in hopes of bettering them while he better himself. It began by volunteering as a camp counselor from middle school through high school, and grew via mentorship and tutoring in college all the way to his membership role in the 100 Black Men and as an advocate for African Americans through his work on the While Black Podcast. Vince wholeheartedly believes James Baldwin's quote “To be Negro in this country and to be relatively conscious is to be a rage almost all the time”. However, he chooses to channel that rage into a place that allows him to change the narrative on black folks while he helps to empower those same black folks.   Earning his undergraduate degree in Civil Engineering from Southern University A&M in Baton Rouge LA (1999) and his MBA from Queens University in Charlotte NC (2005), Vince has gained valuable experience in multiple industries.   He has excelled in multiple industries and enjoyed a career spanning 20+ years with opportunities in Engineering, Consumer packaged goods, Corporate retail giants, and now the Social/tech industry.   In addition, he is a successful entrepreneur and founder of Aveo Big and Tall Golf Apparel which rose to become the #1 big and tall golf apparel offering in Golfsmith stores and was distributed nationally and internationally via various outlets including but not limited to Dicks Sporting Good, GolfSmith, and Golf Galaxy. He has since sold the rights to the Aveo name and divested from the company.   However, he has altered his focus by aligning his passions with his promise and ensuring his time is invested accordingly as he focuses on improving the black world and the global community through and with black people. His latest endeavor is laser-focused on impacting and improving the people around him. Specifically, he is the creator and co-host of the While Black Podcast a podcast focused on empowering, educating, and inspiring African Americans to go and grow. While Black tells stories by, from, and for African Americans and pairs those stories with expert and credible guests who can communicate wisdom and success strategies helping us to achieve, accomplish, and overcome.   Connect with Darius: • Facebook: @whileblackpodcast • Instagram: @while_black • Twitter: @Whileblackpc   Topics Discussed in this Episode: • The universal language and common connection among mothers of all races and how Darius and I both believe mothers will be critical to making change  • Darius' quest to be authentically who he is as a 6'4, 300-pound dark-skinned Black man. How he has struggled to stand tall and shine while also consciously shrinking because people's first reaction to him is fear   • The question about fatherhood Darius asks himself all the time…” How do I raise fearless children when I am a fearful parent?”  • A heartbreaking but powerful “epic snapshot moment” with his son made Darius realize his words were getting through to him and that his son would be part of making change • How those committed to anti-racism and new to this can begin and the reason why Darius seeks “partnership” over saviorism or “help” • The three-fold challenge Darius gave us, including the specific movies that Darius thinks we should all watch to shift our understanding and perspective • How we all need each other to get free    Resources Mentioned: • While Black Podcast • Ahmaud Arbery Is All of Us – Can I Live?  • American Son|Netflix • When They See Us|Netflix • 13TH|Netflix • Ep 07: Living Out Loud with Jenjii Hysten • Revisited: Beyond the Trauma: Legacy, Compassion and Change with Mothers Against Police Brutality Co-Founder Sara Mokuria • Ep 55: From Grief to Advocacy and a Circle of Mothers with Trayvon Martin's mother Sybrina Fulton • Desiree Adaway and Diversity is an Asset  • Podcast Movement • Justice for Josiah   This Episode's Challenge:   Darius gave us a threefold challenge:   • There is bias inside all of us. We all have it. Try our very best to recognize when our unconscious bias fires. Try to pay attention every time we see or meet a Black person…if our initial intent is to walk in the other direction, stop for a moment and ask yourself why?  • Meet someone new and be the first one to say hello and to really see the humanity in them. • Be more intentional in our actions and in whatever media we digest so that we are aware of what's really happening and what others are really going through.

An interview with Dr. Tian Zhang from UT Southwester Medical Center in Dallas, TX, author on "Management of Metastatic Clear Cell Renal Cell Carcinoma: ASCO Guideline." Dr. Zhang reviews the guideline recommendations for the treatment and management of patients with metastatic clear cell renal cell carcinoma and it's implications for clinicians and patients. Read the full guideline at www.asco.org/genitourinary-cancer-guidelines.   TRANSCRIPT Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast series brought to you by the ASCO Podcast Network, a collection of nine programs covering a range of educational and scientific content and offering enriching insight into the world of cancer care. You can find all the shows, including this one at asco.org/podcasts.  My name is Brittany Harvey and today I'm interviewing Dr. Tian Zhang from UT Southwestern Medical Center in Dallas, Texas, one of the authors on 'Management of Metastatic Clear Cell Renal Cell Carcinoma: ASCO Guideline'. Thank you for being here, Dr. Zhang.  Dr. Tian Zhang: Absolutely. Thank you so much for having me, Brittany.  Brittany Harvey: Great! First, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The full conflict of interest information for this guideline panel is available online with the publication of the guideline in the Journal of Clinical Oncology.  Dr. Zhang, do you have any relevant disclosures that are directly related to this guideline topic?  Dr. Tian Zhang: Yes, I have received past research funding from Novartis, Merck, and Pfizer, as well as advisory board and consulting fees from Merck, Exelixis, Pfizer, BMS, Eisai, and Aveo. All of these industry partners have approved therapies in renal cancer. For the complete list, our audience can refer to the guideline's publication.  Brittany Harvey: Great, thank you for those disclosures. Then starting off on the content of this guideline, can you give us an overview of the purpose and scope of this guideline?  Dr. Tian Zhang: Sure. This is a guideline for recommendations for the treatment and management of patients with metastatic clear cell kidney cancer. ASCO gathered 14 colleagues, including myself, that were considered kidney cancer experts from around the world, and we performed a systematic literature review to guide treatment recommendations in metastatic clear cell kidney cancer.  In the series of ASCO clinical practice guidelines for genitourinary cancers, we hope this guideline will provide recommendations for kidney cancer treatment with supporting data and evidence, particularly given the therapeutic landscape changes since about 2017.  Brittany Harvey: Then I'd like to review those recommendations that you just mentioned of this guideline. So, this guideline covers six overarching clinical questions. So, I'd like to go question by question for our listeners, starting with how is metastatic clear cell renal cell carcinoma is defined and how is it diagnosed?  Dr. Tian Zhang: In this portion, we recommended a gold standard of comparing metastatic tissue outside of the primary site to the primary tumor. We discuss adding in staining for PAX8 as well as CA-IX for clarity of clear cell histology.  The timing is also pretty important in the timing of initial diagnosis and nephrectomy until the appearance of metastatic sites on scans, and radiographic diagnosis is therefore used in settings where prior diagnoses of clear cell kidney cancer has been established and when a metastatic lesion is not accessible for biopsy or when there's clear, measurable disease within a year of the initial diagnosis.  Brittany Harvey: Understood. And then in the next section of the guideline, what is the role of cytoreductive nephrectomy in metastatic clear cell renal cell carcinoma?  Dr. Tian Zhang: In this section, we recommend that cytoreductive nephrectomy should be considered for select patients who present with de novo metastatic clear cell kidney cancer to palliate hematuria or pain or to remove the bulk of tumor burden.  We discuss some past trials in the settings of interferon alpha, and VEGF inhibitors and also recommend consideration of ongoing clinical trials in the era of immunotherapies. There are two such trials that are ongoing, PROBE and Cyto-KIK, that are actively accruing patients.  Brittany Harvey: Great. And then the guideline goes into options for systemic treatment. So, what are the preferred options for first-line systemic treatment?  Dr. Tian Zhang: This is probably our most extensive section, as first-line systemic treatments have changed and expanded greatly over the past five years. First, we recommend considering active surveillance for select patients with the following criteria: those who have IMDC favorable or intermediate-risk disease, those with limited or no disease-related symptoms, and also those with a long interval between nephrectomy and the development of metastasis.  Second, we recommend IMDC risk stratification to then determine treatment selection. Those with IMDC intermediate or poor risk factors should be offered combination treatment with either two immune checkpoint inhibitors or an immune checkpoint inhibitor with an anti-angiogenic VEGF tyrosine kinase inhibitor.  We provide strong level of evidence with the completed phase three trials in this first-line setting of ipilimumab and nivolumab, axitinib with pembrolizumab, axitinib with avelumab, cabozantinib with nivolumab, and lenvatinib with pembrolizumab.  For patients with IMDC favorable-risk disease, we recommend an immune checkpoint inhibitor with a VEGF tyrosine kinase inhibitor which may be offered over VEGF TKI alone for those patients who are candidates for immunotherapy.  In addition, VEGF monotherapy or an immune checkpoint inhibitor monotherapy may be offered for select patients who have certain coexisting medical conditions.  In addition, we have discussed this long history of high dose interleukin-2 treatments and that this may still be considered in first-line treatments for certain patients while discussing the significant toxicity of IL-2 relative to the newer immunotherapy regimens.  And finally, we encourage the participation and enrollment into first-line clinical trials when available. A couple of the current ongoing ones include PDIGREE and the LITESPARK-012 Trial.  Brittany Harvey: I appreciate your reviewing those options and the level of evidence along with those ongoing trials for patients. So, then following those recommendations for first- line that you just went through, what is recommended for the second or later line systemic treatment?  Dr. Tian Zhang: Subsequent treatment in later lines after initial treatment of refractory renal cell carcinoma depends largely on the initial treatment choices.  We recommend nivolumab or cabozantinib for patients who had prior progression on a VEGF TKI alone based on the large phase three trials CheckMate 025 and METEOR respectively that gain the approvals for nivolumab and cabozantinib.  For patients with disease progression on a combination immunotherapy, a VEGF TKI should be considered. Those who progress after initial combination therapy with a VEGF TKI and an immune checkpoint inhibitor should then be offered an alternative VEGF TKI as a single agent.  And finally, for those who have limited sites of disease progression, local treatment with radiation, thermal ablation, or surgical excision could be offered with continuation of the immunotherapy.  Brittany Harvey: Thank you for reviewing those second and later line treatment options. So, then following that, what did the panel recommend regarding metastasis-directed therapy?  Dr. Tian Zhang: There have been some recent studies looking at metastasis-directed treatments, especially for patients with a low volume of metastases. These can include surgical resection, ablation, or radiation therapy. And surgical resection and radiation have not actually been directly compared.  And so, for those patients, we would recommend a tailoring treatment based on sites of disease. For those patients who do have surgical resection, subsequent VEGF TKIs are not usually recommended based on a prior phase two trial.  Brittany Harvey: Understood. And then this guideline addresses a couple special subsets of patients. And so, what are those subsets, and what considerations should be applied to the treatment of these special subsets of metastatic clear cell renal cell carcinoma?  Dr. Tian Zhang: For the special subsets of patients, we considered patients with bone metastases, patients with brain metastases, and also patients with sarcomatoid features on histology.  For those patients with bone metastases, we recommend bone-directed radiation as well as a bone resorption inhibitor with either a bisphosphonate or a RANK ligand inhibitor.  We do not have a recommendation on optimal systemic treatments, although given the presence of the MET receptor on bone metastases, regimens containing cabozantinib, which targets the MET receptor in addition to other receptors, may be preferred.  For those patients who have brain metastases, no definite guidance for treatment can be made given many patients with brain metastases were excluded from the initial trials.  The overall efficacy of the systemic therapies is low for controlling metastatic kidney cancer in patients with brain metastases. We do recommend local treatment with radiation and or surgery to be undertaken based on the pattern of intracranial metastases. And we refer readers and the audience to a recent guideline from ASCO, ASTRO, and SNO on the management of brain metastases.  And finally, for patients who have sarcomatoid features on pathology, an immune checkpoint inhibitor-based combination should be chosen in the first line setting. And this is based on multiple phase three trials that have shown improvement in clinical outcomes for patients treated with immunotherapy combinations compared to sunitinib alone.  Brittany Harvey: Thank you for viewing all these recommendations. The guideline expert panel certainly covered a lot of questions on the treatment and management of metastatic clear cell renal cell carcinoma.  So, then in your opinion, Dr. Zhang, what is the importance of this guideline and how does it impact clinicians?  Dr. Tian Zhang: Sure. You know, in the past 10 years, our treatment options for metastatic kidney cancer have greatly expanded and multiple options are now available. For busy clinicians who may not treat kidney cancer, especially in the metastatic setting often or on a routine basis, this set of guidelines provides a high-level approach to the common management scenarios that clinicians are often faced with.  My fellow committee members and I hope that these guidelines will provide a comprehensive one-stop document that is relevant and updated for the busy clinician taking care of patients with metastatic kidney cancer.  Brittany Harvey: Great! And then finally, how will these guideline recommendations affect patients with metastatic clear cell renal cell carcinoma?  Dr. Tian Zhang: The fact that our treatment options for metastatic kidney cancer have improved clinical outcomes, including extending the time until progression as well as overall survival, is truly wonderful news for patients who are diagnosed with metastatic kidney cancer today.  If patients are directly reading these guidelines, they can also see whether overall recommendations align with their recommended course of treatment, with the caveat that every patient's care is tailored to them based on coexisting medical conditions and concurrent medications. But we hope these guidelines will be helpful for all of our patients.  Brittany Harvey: Yes, it's great to see improved clinical outcomes for patients. So, I want to thank you for all of your work on this guideline and for taking the time to review the guideline recommendations and its impact.  Dr. Tian Zhang: Sure. I really appreciate ASCO giving this time and opportunity, Brittany, and also the audience for their interest in the clinical guidelines for metastatic clear cell renal cell carcinoma.  Brittany Harvey: And thank you to all of our listeners for tuning in to the ASCO Guidelines podcast series.  To read the full guideline, go to www.asco.org/genitourinary-cancer-guidelines.

Guest host Dr. Neeraj Agarwal, of the University of Utah Huntsman Cancer Institute and the ASCO Daily News editor-in-chief, discusses key therapeutic advances in mRCC and mUC, as well as new research that proposes periodic scans to monitor patients with mCSPC for disease progression, with Dr. Jeanny-Aragon-Ching of the Inova Schar Cancer Institute.  Transcript:  Dr. Neeraj Agarwal: Hello and welcome to the ASCO Daily News podcast. I'm Dr. Neeraj Agarwal, the director of the Genitourinary Oncology Program, a professor of medicine at the University of Utah Huntsman Cancer Institute, and editor-in-chief of the ASCO Daily News.  My guest today is Dr. Jeanny Aragon-Ching, who is a medical oncologist and the Clinical Program Director of Genitourinary Cancers at the Inova Schar Cancer Institute in Virginia.  Today, we will be discussing key posters in genitourinary (GU) oncology that will be featured at the 2022 ASCO Annual Meeting. Our full disclosures are available in the show notes and disclosures of all guests on the podcast can be found on our transcripts at asco.org/podcast.  Jeanny, it is great to have you on the podcast today.  Dr. Jeanny Aragon-Ching: Thanks, Neeraj. It's a pleasure for me to be here as well.  Dr. Neeraj Agarwal: Jeanny, let's begin with Abstract 4510. This is a trial that represents a growing interest among researchers worldwide in the microbiome and how it is impacted by antibiotics and how it modulates immune checkpoint inhibitor response. Can you tell us about this study?  Dr. Jeanny Aragon-Ching: Thanks, Neeraj, I would be happy to. So, the title of the abstract is, “Characterization of the Microbial Resistome in a Prospective Trial of CBM 588 in Metastatic Renal Cell Carcinoma Offers Mechanism for Interplay Between Antibiotic Use and Immune Checkpoint Inhibitor Activity.”  So, this is an interesting abstract that originated likely from the observation that getting antibiotics while on checkpoint inhibitors typically results in worse outcomes, perhaps because antibiotics can clear the normal gut flora and thereby increase these pathogenic antibiotic-resistant bacteria.  Now, on the other hand, there were some retrospective studies using a live microbial product called CBM 588, which seems to improve outcomes in patients on checkpoint inhibitors and getting antibiotics.  So, the idea, therefore, is that shifting the genes encoding antimicrobial resistance could result in a better checkpoint inhibitor response. So, this Abstract 4510 is a small study conducted by Dr. Nazli Dizman and Dr. Sumanta (Monty) Kumar Pal, and colleagues, and enrolled 29 metastatic clear cell RCC patients with intermediate or poorest disease. And they were stratified into receiving either nivolumab or ipilimumab compared to nivo/IPI with CBM 588.  Now stool samples were collected at baseline in week 12. And they did this whole metagenome sequencing to analyze a stool microbiome composition, and they also looked at the antibiotic resistance genes for the most common classes of antibiotics.  The results showed an astounding improvement in objective responses. So, 58%, for instance, in nivo/IPI and the CBM 588 arm compared to only 20% in the nivo/IPI arm. And it seems like also the antibiotics resistance genes were also decreased in those getting the CBM 588 alongside nivo/IPI. Therefore, responses were improved by shifting the gut microbiome alone. So, these findings were published actually recently by these authors in Nature Medicine. So, in case anyone wants to take a deep dive, it would be a good interesting read for this dataset.  Dr. Neeraj Agarwal: Very interesting, indeed. Jeanny, what is the main message here for our colleagues?  Dr. Jeanny Aragon-Ching: I think, Neeraj, the key takeaway message is that this is a very provocative proof of concept trial that suggests shifting the gut microbiome has the potential to improve responses to checkpoint inhibitors and outcomes. So, this is a very up-and-coming trial and is seen also across the board in other cancers.  Dr. Neeraj Agarwal: Thanks, Jeanny. Moving on to urothelial cancer, there is a poster that I think is a must-see for our colleagues. This is Abstract 4577 titled, “Defining Platinum Ineligible Patients with Metastatic Urothelial Carcinoma.”  Dr. Jeanny Aragon-Ching: So, Neeraj, what can you tell us about this abstract?  Dr. Neeraj Agarwal: So, over the past few years, there has been a tremendous evolution in the treatment landscape for patients with metastatic urothelial carcinoma. For over 40 years the standard of care for these patients has been cisplatin-based chemotherapy.  However, approximately 50% of patients are cisplatin-ineligible, due to underlying comorbidities, and are offered carboplatin as an alternative. So, although the checkpoint inhibitors pembrolizumab and atezolizumab were approved as first-line therapy for these patients in 2017, the U.S. Food and Drug Administration (FDA) has now restricted the use of first-line pembrolizumab to platinum ineligible patients with metastatic urothelial carcinoma.  The challenge we face as oncologists since the FDA restriction is the absence of a formal definition of platinum ineligibility and the inclusion of this definition in the guidelines. So, in Abstract 4577, Drs. Shilpa Gupta and Jonathan Rosenberg, along with the team present an updated consensus definition for platinum ineligibility based on an online survey of 60 genitourinary oncologists in the United States.  Based on the results from this survey, any patient with metastatic urothelial carcinoma, meeting 1 of the following 5 clinical and or laboratory parameters should be considered platinum ineligible, and these are 1 of the following: an ECOG performance status of 3 or more, creatinine clearance of fewer than 30 mils per minute, or peripheral neuropathy of grade 2 or more, or heart failure class of 3 or more—so, this is NYHA heart failure class of 3 or more—and lastly, the combination of performance status of 2 or more, plus a creatinine clearance of less than 30 mils per minute.  Dr. Jeanny Aragon-Ching: Well, this is a timely update, Neeraj. So, what do you think is a key takeaway from this abstract?  Dr. Neeraj Agarwal: These criteria based on simple and easily available clinical and or laboratory parameters will now allow us to readily define platinum ineligibility in our patients with metastatic urothelial carcinoma, which is a need in busy clinics, both in academic and community settings.  So, I think once published and obviously once endorsed by guidelines, we really would like to be able to use this criterion to quickly define platinum ineligibility in our clinics.  Dr. Jeanny Aragon-Ching: Agree. Yeah.  Dr. Neeraj Agarwal: So, Jeanny, let me switch the gears. PSMA testing is a hot topic this year. And there is an abstract that could potentially have an impact on future guidelines, and how we will practice further down the road.  So, I'm referring to the Abstract 5088 titled, “Predictive Value of Extra Prostatic Disease Detection by Preoperative PSMAPET for Biochemical Recurrence-free Survival in Patients with Otherwise Localized Prostate Cancer and Who are Treated with Radical Prostatectomy.”  So, this is a follow-up analysis of a multicenter prospective phase 3 imaging trial. So, could you please tell us more about this abstract where they are using PSMA PET scan in the preoperative localized prostate cancer setting?  Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. So, you may recall that the multicenter prospective phase 3 imaging trial that garnered gallium PSMA approval by the FDA was actually based on this study that looked at the intermediate and high-risk patients with prostate cancer undergoing radical prostatectomy and lymph node dissection, and they underwent prior gallium PSMA PET scanning for pelvic nodal metastases prior to surgery.  So, this was actually previously reported by Dr. Calais and group. Now they are reporting on Abstract 5088 as a post hoc analysis of the same population and group of patients looking for extraprostatic disease. And the final pathology was also correlated to look at nodal disease in these patients in order to predict biochemical recurrence, so they follow these patients for biochemical recurrence occurrence.  So, of the 36% of patients who did undergo radical prostatectomy after they underwent PSMA PET scan, about 41% of them recurred with biochemical recurrence, and 40% of them underwent some kind of salvage therapy or some treatment.  What was very interesting was when they looked at the biochemical recurrence-free survival. It was better in those who were PSMA negative, and that recurrence-free survival was easily about 33 months, compared to only about 7.3 months in those who were PSMA-positive scans.  Furthermore, the ones who had the longest and the highest biochemical recurrence-free survival, intuitively, were those who were node-negative and PSMA PET-negative, so probably not surprisingly. And that rate was about 46 months—close to 4 years. Whereas those who are node-positive on final pathology and their PSMA PET was also positive, they only had about 3 months of biochemical recurrence-free survival.  Dr. Neeraj Agarwal: Very interesting. So, it looks like the PSMA PET scan is predicting biochemical recurrence-free survival in localized prostate cancer settings. So, Jeanny, what is the key takeaway from this trial?  Dr. Jeanny Aragon-Ching: I think, Neeraj, the bottom line is that patients with extraprostatic disease that is detected by their preoperative PSMA PET scan does predict strongly a high risk of biochemical relapse, and this can really be an additional tool that clinicians can use to help inform and guide future therapy.  Dr. Neeraj Agarwal: Thanks, Jeanny. The research on preoperative PSMA testing and its implications on future treatment strategies in the setting is going to be really interesting to watch in the very near future.  Dr. Jeanny Aragon-Ching: Yes, absolutely. I really think we should also discuss Abstract 5072, along those lines, the importance really of radiographic monitoring for disease progression in patients with metastatic hormone-sensitive prostate cancer.  Dr. Neeraj Agarwal: Yes, thanks for reminding and this is Abstract 5072. This is a post hoc analysis of the ARCHES trial, titled, “Radiographic Progression in the Absence of PSA Progression in Patients with Metastatic Hormone-sensitive Prostate Cancer.”  During the last several years, we have seen many of these agents typically given for gastric resistant prostate cancer moving upfront to the castration-sensitive prostate cancer setting. This is especially true for androgen receptor access targeting agents such as abiraterone, enzalutamide, and apalutamide, all being now approved for patients with metastatic castration-sensitive prostate cancer.  What is noteworthy from all these trials, and is reported in Abstract 5072, is the use of imaging studies to evaluate disease progression. So, in Abstract 5072, Dr. Andrew Armstrong and Dr. Arun Azad performed a post hoc analysis of the ARCHES trial to investigate the concordance between radiographic progression and the PSA Progression as defined by PCWG2 criteria, or between radiographic progression and any rise in the PSA above nadir, in patients who were being treated with this novel hormonal therapies, in this case, enzalutamide for metastatic castration sensitive prostate cancer.  And as a quick reminder, ARCHES was a phase 3 trial that showed a significant reduction and radiographic progression-free survival and improved overall survival for patients with metastatic castration sensitive prostate cancer treated with enzalutamide plus androgen deprivation therapy (ADT) versus those treated with placebo plus androgen deprivation therapy.  So, very interestingly, the findings from this study indicate that 67% of patients on the enzalutamide plus ADT arm did not have [Prostate Cancer Clinical Trials Working Group 2 criteria] PCWG2-defined prostate-specific antigen (PSA) progression at the time of radiographic progression. And discordance was present in the ADT-only arm as well, where they found 42% of patients on the ADT-only arm had radiographic progression but did not have PCWG2-defined PSA progression.  Interestingly, this discordance of radiographic disease progression was also seen with any rise in the PSA above nadir. And I personally found this information to be very clinically relevant when we are seeing the majority of patients actually experiencing radiographic disease progression, not experiencing PSA progression at the same time.  Dr. Jeanny Aragon-Ching: Yeah, absolutely. I agree with that, Neeraj. So, very interesting data. So, what do you think is the key takeaway message for the clinicians listening to us?  Dr. Neeraj Agarwal: I'll make the message very simple. I think the message is that patients with metastatic castration-sensitive prostate cancer need to be monitored for disease progression with periodic scans, and PSA monitoring alone is not sufficient in the majority of these patients.  Again, we cannot undervalue the role of periodic imaging studies in these patients so that we can timely diagnose them to have disease progression.  Dr. Jeanny Aragon-Ching: I agree with that.  Dr. Neeraj Agarwal: Jeanny, the last abstract I would like to mention before we wrap up the podcast is Abstract 4509, the results from the phase1 live SPARC 001 study. So, can you please tell us more about this study titled, “Phase-1 Live SPARC 001: The Study of Belzutifan in Advanced Solid Tumors,” which is an update of the renal cell carcinoma cohort with more than 3 years of total follow up?  Dr. Jeanny Aragon-Ching: Thanks, Neeraj. So, while the current therapeutic landscape for patients with metastatic clear cell renal cell carcinoma (RCC) has changed dramatically over the past several years, with significant improvement in patient outcomes. Most patients unfortunately still experience disease progression on current treatments.  So, in-depth molecular profiling of clear cell RCC has revealed recurrent loss of function mutations in VHL in actually greater than 90% of patients. So, the VHL protein, as you will recall, is part of the oxygen-sensing pathway, regulating levels of HIF which is hypoxia-inducible factor protein, it's a transcriptional activator that mediates the response to hypoxic conditions. So, HIF-2α is a key oncogenic driver in RCC.  So, previous data you may recall from the phase-1 Live SPARC 001 trial was designed to evaluate belzutifan so, this was a novel HIF-2α inhibitor which showed durable anti-tumor activity and acceptable safety profile in patients with metastatic clear cell RCC.  So, in Abstract 4509, Drs. Jonasch and Toni Choueiri presented updated results from this trial after more than 3 years of follow-up. Of the 55 patients enrolled 16% of patients remained in treatment. And 62% of patients had discontinued treatment because of, unfortunately, disease progression.  The median progression-free survival (PFS) for the total cohort was 14.5 months. And the overall disease control rate was 80%. Forty percent of patients experienced grade 3 treatment-related adverse events with the most frequent ones being anemia and hypoxia.  There were no great 4 or 5 treatment-related adverse events. And these results, therefore, show that belzutifan monotherapy continues to show a high rate of disease control and a safety profile in a heavily treated population of patients with metastatic RCC. So, it is great to see that there were no new safety signals.  Dr. Neeraj Agarwal: Very nice data indeed. So, Jeanny, what is the key takeaway message here for our listeners?  Dr. Jeanny Aragon-Ching: Yeah, I think the message here is that the use of belzutifan monotherapy continues to show efficacy and safety in patients with metastatic clear cell RCC, which have progressed on multiple prior contemporary therapies, and there are phase 3 trials currently underway.  Dr. Neeraj Agarwal: Jeanny, any final thoughts before we wrap up the podcast today?  Dr. Jeanny Aragon-Ching: Thanks, Neeraj. I think it's a really exciting time to be in genitourinary (GU) oncology, and I'm truly looking forward to seeing some great sessions at the 2022 ASCO Annual Meeting.  Dr. Neeraj Agarwal: Thank you, Jeanny, for sharing your insight with us today. It was a great conversation. And thank you to our listeners for joining us today. You will find links to the abstracts discussed today on the transcript of this episode.

Dr. Neeraj Agarwal, of the University of Utah Huntsman Cancer Institute, tells host Dr. John Sweetenham, of the UT Southwestern Harold C. Simmons Comprehensive Cancer Center, about the first study to examine the quality of diagnosis and treatment of breast cancer in sex and gender minority patients and other key studies on disparities associated with access to clinical trials and rising drug costs.  Transcript Dr. John Sweetenham: Hello, I'm John Sweetenham, the associate director for Clinical Affairs at UT Southwestern Harold C. Simmons Comprehensive Cancer Center and host of the ASCO Daily News podcast.  I'm delighted to welcome my friend and colleague Dr. Neeraj Agarwal, the director of the Genitourinary Cancers Program and a professor of medicine at the University of Utah's Huntsman Cancer Institute. Dr. Agarwal also serves as editor-in-chief of the ASCO Daily News.  Today, he'll be sharing his insights on compelling studies that will be featured at the 2022 ASCO Annual Meeting, addressing access to clinical trials, disparities associated with high deductible health plans, rising drug costs, and more.  Our full disclosures are available in the show notes and disclosures of all guests on the podcast can be found on our transcripts at asco.org/podcasts.  Neeraj, it's great to have you back on the podcast.  Dr. Neeraj Agarwal: Thanks, John.  Dr. John Sweetenham: Neeraj, let's begin with Abstract 6503. This study looks at the impacts of high deductible health plans on delays in metastatic cancer diagnosis. What do you think about this study and why should it be on our radar?  Dr. Neeraj Agarwal: Well, John, in high deductible health plans, patients are liable for the cost of all cancer-related care, with the exception of screening tests, until their annual deductible is met. Due to increased out-of-pocket costs, patients may postpone seeing a physician for concerning symptoms or diagnostic testing, leading to delayed diagnosis.  So, in this study, Mr. Nicholas Trad and J. Frank Wharam assessed the impact of high deductible health plans on the timing of metastatic cancer detection.  The authors leveraged a nationally representative cohort of more than 340,000 privately insured members whose employers mandated a switch from a low deductible of less than $500 plan to a high deductible plan of more than $1,000.  So, the group consisted of more than 1 million individuals in a contemporary time frame, whose employers offered only low deductible plans. Participants were matched based on multiple baseline characteristics, time to metastatic cancer diagnosis, and the before and after switching to high deductible health plans was investigated using a weighted Cox proportional-hazards model.  After matching, there were no systematic differences between the 2 groups with regards to baseline characteristics, and there were no differences in time to metastatic cancer diagnosis prior to the switch to high deductible health plans.  However, after the employer-mandated switch to the high deductible health plans, these participants had lower odds of metastatic cancer diagnosis, which was significant, statistically speaking, and indicates delayed detection of metastatic cancer diagnosis relative to the control group.  Dr. John Sweetenham: This is certainly concerning data, Neeraj. What's your key takeaway from this study?  Dr. Neeraj Agarwal: So, the key takeaway from the study is that compared with conventional health plans, high deductible health plans are associated with delayed detection of metastatic cancer, implying that patients postpone seeking care for concerning symptoms or even defer diagnostic testing when they're exposed to high-cost sharing.  Dr. John Sweetenham: Thanks, Neeraj. So, let's continue with this theme of the financial burden of cancer care for our patients. Of course, we're all aware of the rising costs of targeted oral therapies, and this was addressed in Abstract 6504, where the study looks at the rising costs of targeted oral treatments among Medicare beneficiaries. And the study reported a substantial increase in the total cost and out-of-pocket costs of these medicines. Can you tell us more about this abstract?  Dr. Neeraj Agarwal: Yes! So, due to the rapidly rising cost of targeted oral anticancer medicines, Drs. Meng Li and Ya-Chen T. Shih examined recent trends and the financial burden of these oral medicines among patients with cancer with Medicare Part D insurance. So, eligible patients in the SEER-Medicare database had to be 65 years and older and had to have one primary cancer diagnosis.  The investigators estimated the trends in the share of patients who used targeted oral anticancer medicines, the percentage of users reaching catastrophic coverage, and the total and patient out-of-pocket spending on these medicines in the catastrophic phase in a year.  So, from 2011 to 2016, the uptake of these oral anti-cancer medicines increased from approximately 4% to 9%. The percentage of those who reached catastrophic coverage increased from 55% to 60%.  Among those who reached the catastrophic phase, the mean total annual gross spending on oral anti-cancer medicine increased 4-fold from approximately $16,000 to $64,000. And the mean out-of-pocket spending for the patients rose from approximately $600 to $2600.  Dr. John Sweetenham: Yes, this is more evidence that the financial toxicity generated from an increase in spending and out-of-pocket costs is going to have serious impacts on our patients. Would you agree with that, Neeraj?  Dr. Neeraj Agarwal: Yes, John. The key takeaway from this study is that the financial burden of these oral anti-cancer medicines continues to increase. In the relatively short period of time, we see here, 5 years from 2011 to 2016, there was a 4-fold increase in the total cost and out-of-pocket cost of these medicines. And in my view, these findings warrant immediate actions to rein in drug prices and cap out-of-pocket spending for our patients.  Dr. John Sweetenham: Absolutely. It's very difficult to know where this will end unless we see some kind of slowdown in these rising costs. I'm going to change gears just a little bit now to address the access to clinical trials, which is the subject of Abstract 6505.  This study looks at the implementation of the Affordable Care Act Medicaid expansion, which was associated with an almost threefold increase in the proportion of patients using Medicaid in cancer clinical trials by early 2020. What are your thoughts on this study?  Dr. Neeraj Agarwal: As you said, the Affordable Care Act Medicaid expansion resulted in increased use of this platform across the nation. However, its impact on access to clinical trials has not been examined.  So, in this study, Dr. Joseph Unger and Dr. Dawn Hershman examined the number and proportion of patients insured by Medicaid at enrollment over time using data from the SWOG Cancer Research Network.  In addition, they also examined all patients, 18 to 64 years old, enrolled in treatment trials between 1992 to 2020 using Medicaid versus private insurance.  So, the implementation of the Affordable Care Act Medicaid expansion was associated with a nearly threefold increase from 7% to 21% in the proportion of patients using Medicaid in cancer clinical trials by early 2020.  The increase per year of Medicaid uses for patients in these treatment trials from states that implemented the Affordable Care Act Medicaid expansion was 27% compared to 7% for patients from other states who did not implement this platform of Affordable Care Act Medicaid expansion.  So, the key takeaway from the study is that better access to clinical trials for more vulnerable patients is critical to improving confidence in how generalizable these trial findings are. In addition, these results suggest that the recently enacted Cancer Treatment Act may continue to improve access to clinical trials for those with Medicaid insurance or those who are vulnerable patients.  Dr. John Sweetenham: Yes, I think this is a really important study which adds to the growing literature on the benefits of the Affordable Care Act and Medicaid expansion on cancer care in general, in this case, specifically related to clinical trials. So, so important, I think.  On that theme of equity, I think the next 2 abstracts we're going to discuss address specific aspects of equity, which I think are both interesting and really important. So, Abstract 6510 has interesting research which conveys an urgent need to ensure equitable patient-reported access and implementation and to address the greater reported symptom burden among minority patients. Why do you think this study is important?  Dr. Neeraj Agarwal: The routine collection of patient-reported outcomes for patients with cancer is an evidence-based practice and a critical component of high-quality cancer care, but the real-world adherence and reporting patterns are poorly understood.  In this study, Dr. Samuel Takvorian and Dr. Ravi Parikh examined differences in adherence to the collection of patient-reported outcomes and reported symptoms by race and ethnicity.  This was a retrospective cross-sectional study using de-identified electronic health record data from an National Cancer Institute (NCI)-designated Comprehensive Cancer Center. The participants included adults seen in follow-up at 1 of the 2 medical oncology practices—one was in academics and one was in the community—from June 2019 to February 2020. Using ordinary least-squares regression, the authors modeled patient adherence as a function of race or ethnicity, and this was adjusted for age, sex, insurance, median area income, ECOG, performance status, and many other patient-related characteristics.  The results show that adjusted mean PRO adherence and reported symptoms varied by race and ethnicity, with Black and Hispanic patients being less likely to complete PRO questionnaires, but reporting significantly higher symptom burden compared to the White patients.  Dr. John Sweetenham: Right. So, it seems that more work is needed to ensure equitable access and adherence to PRO questionnaires so we can better address the symptom burden of our minority patients.  Dr. Neeraj Agarwal: Correct, John. In this large cohort reflecting real-world PRO collection patterns, Black and Hispanic patients were less likely than White patients to complete these PRO questionnaires, but more likely to report more severe symptoms. And I think there is an urgent need to ensure equitable PRO access and implementation and to address the greater reported symptom burden among minority patients.  Dr. John Sweetenham: Let's continue the theme of health equity and cancer care equity into the use of telemedicine. Of course, we saw a massive expansion of telemedicine for patients with cancer during the COVID-19 pandemic.  But studies are emerging now to show that there have been substantial disparities among the Black, uninsured, non-urban, and less affluent patients who are less likely to use telemedicine services.  Abstract 6511 reminds us that telemedicine may expand access to specialty care, but the proliferation of these services may widen cancer care disparities if vulnerable populations don't have equitable access. Can you tell us more about this abstract?  Dr. Neeraj Agarwal: These are indeed very interesting findings, John. The COVID-19 pandemic was associated with declines in in-person clinical visits, with a concurrent increase in the use of telemedicine.  In this study, Dr. Gregory S. Calip assessed demographic and socioeconomic factors associated with telemedicine use among patients initiating treatment for 21 common cancers at community oncology clinics.  This was a retrospective study and made use of the nationwide Flatiron electronic health record derived de-identified database of patients with cancer. The authors focused on differences in telemedicine use across race and ethnicity, insurance coverage, rural versus urban areas, and socioeconomic status.  They used logistic regression models for this analysis, which was adjusted for clinical characteristics to examine differences in telemedicine use among these different cohorts.  Results indicate Black patients were significantly less likely to use telemedicine services compared to White patients. Telemedicine use was also significantly lower among patients without documented insurance than well-insured patients. It was also lower in patients from rural and suburban areas versus patients who were living in urban areas. Lastly, telemedicine use was significantly lower in patients in the least affluent areas than those in the most affluent areas.  So, during the COVID-19 pandemic, nearly one-fifth of patients initiating cancer treatment using telemedicine services—among these patients, we see substantial disparities. So, Black, uninsured, non-urban, and less affluent patients were less likely to use telemedicine services.  So, the take home message from this study is that while telemedicine may expand access to care, the proliferation of these services may actually widen cancer care disparities if vulnerable populations do not have equitable access to these services.  Dr. John Sweetenham: Thanks, Neeraj. So, the final study that we'll discuss today also looks at another aspect of disparities, and that's Abstract 6517. It's a case-controlled study of health care disparities in sex and gender minority patients with breast cancer. What are the key takeaways from this study?  Dr. Neeraj Agarwal: Disparities and the quality of diagnosis and treatment of breast cancer in sex and gender minority populations are largely undefined. Only 24% of studies funded by the National Cancer Institute capture data on sexual orientation and only 10% capture data on gender identity.  In this case-control study, Drs. Eric Eckhert and Allison W. Kurian matched sex and gender minority patients with breast cancer to cisgender heterosexual controls in the Stanford University health care database. Ninety-two sex and gender minority patients were identified who were then matched by year of diagnosis, age, stage of cancer, presence of estrogen receptor (ER), and HER-2/neu receptor status to cisgender heterosexual controls within this database.  Additional data on demographics, diagnosis, treatment, and relapse were then manually abstracted from the electronic health care records. The sex and gender minority cohort were comprised of 80% lesbians, 13% bisexuals, and 6% transgender men.  One of the most pertinent findings was a significant, almost twice as much delay in time to diagnosis from the onset of symptoms in these minority patients versus control. Although there was no difference in the receipt of surgery or surgical radiation or new adjuvant therapy, sex, and gender minority patients were significantly less likely to undergo chest reconstruction surgery, and if they were estrogen receptor-positive, they were significantly less likely to complete at least 5 years of ER directed therapy.  Please also note that sex and gender minority patients used more alternative medicine, had a higher rate of documented refusal of recommended oncology treatments, and they experienced a higher recurrence rate.  So, the key takeaway from this study is that—this is the first study, I really want to congratulate the investigators who examined the quality of diagnosis and treatment of breast cancer in sex and gender minority patients. Several novel potential health care disparities are identified in these patients, which should be further evaluated in population-based studies to inform further interventions.  Dr. John Sweetenham: Neeraj, it's always a pleasure to talk with you and have an opportunity to spend some time with you.

Dr. Neeraj Agarwal, ASCO Daily News editor-in-chief, and director of the Genitourinary Cancers Program at the University of Utah's Huntsman Cancer Institute, highlights key studies on disparities in GU cancers featured at the 2022 ASCO Genitourinary Cancers Symposium. Transcript:   ASCO Daily News: Hello and welcome to the ASCO Daily News Podcast. I'm Geraldine Carroll, a reporter for the ASCO Daily News. In today's episode, Dr. Neeraj Agarwal, the ASCO Daily News editor in chief, will highlight compelling studies on disparities in GU cancers featured at the 2022 ASCO Genitourinary (GU) Cancers Symposium.

I'm Dr. Neeraj Agarwal, the director of the Genitourinary Cancers Program and professor of medicine at the University of Utah Huntsman Cancer Institute. So, I'd like to start with Abstract 20 presented by Dr. Alicia Morgans from the Dana-Farber Cancer Institute. Multiple population-based studies have reported a higher incidence of prostate cancer in Black men. [This disease] usually presents with aggressive features, at an earlier age, and is associated with higher mortality rates compared to White men. In contrast, multiple reports suggest that Black men with advanced prostate cancer also have better survival outcomes to novel hormonal therapies compared to White men. Using electronic medical records retrieved from a urology specialty database, Dr. Alicia Morgans investigated whether improved survival outcomes in Black men treated with enzalutamide are due to better responses compared to White men. So eligible patients, who are chemotherapy and abiraterone naive and included 214 Black men and 1,332 White men with advanced prostate cancer.    Reserves from a multivariate analysis were adjusted for baseline characteristics and indicated a statistically significant delay in clinical progression-free survival for Black men treated with enzalutamide compared to White men. This supports the argument that given equal access to care, Black men may respond similarly or better than White men to treatment for advanced prostate cancer. The next abstract addressing disparities in GU cancers was Abstract 444 presented by Dr. Samuel Washington from UCSF School of Medicine. Radical cystectomy remains the gold standard for muscle-invasive bladder cancer, yet confers significant health care costs. Prior work on the impact of cost commonly relied on comparisons by insurance status and income. Few studies have examined the relationship between the net worth of the household and the encounter type, such as outpatient versus inpatient encounters. As we also know, outpatient encounters are usually cheaper or less expensive than more expensive inpatient encounters.    So, in this intriguing and novel study, Dr. Samuel Washington presented a real-world analysis of demographics, household net worth, health plan cost, out-of-pocket cost, and total health care cost accrued from the day of admission to 90 days after radical cystectomy for muscle-invasive bladder cancer. This was the largest study of its kind and included more than 140,000 commercially insured patients to examine variations in health care utilization by net worth in 90 days after radical cystectomy. Results are very interesting and indicate that patients with lower household net worth were at a greater risk for an acute inpatient encounter and thus higher medical cost, while patients with greater household net worth had greater odds of office visits or outpatient encounters, which are associated with lower cost. So, these findings indicate that a lower household network continues to be a significant factor in health care utilization and higher health care costs, even within a commercially insured patient population. So very interesting findings indeed and these findings definitely should pay for further future studies involving or looking at this aspect of disparities.

I'm Geraldine Carroll, a reporter for the ASCO Daily News. Today in our continuing coverage of the 2022 ASCO Genitourinary (GU) Cancer Symposium. Dr. Neeraj Agarwal, the editor in chief of the ASCO Daily News will share key takeaways from the practice-changing ARASENS trial, which showed promising results in metastatic hormone-sensitive prostate cancer. Dr. Agarwal has no conflicts relating to the topic of this episode and his full disclosures are available in this show notes. Disclosures of all guests on the podcast can be found in our transcripts at asco.org/podcasts. Dr. Neeraj Agarwal: Hello and welcome to the ASCO Daily News podcast. I'm Dr. Neeraj Agrawal, the director of the Genitourinary Cancers Program and professor of medicine at the University of Utah Huntsman Cancer Institute. Let's discuss the results of the practice-changing ARASENS trial in patients with metastatic castration-sensitive prostate cancer as presented at the 2022 ASCO GU Symposium. This abstract, Abstract 13, was presented by Dr. Matthew Smith from the Massachusetts General Hospital and Hartford Medical School. ARASENS is a randomized phase 3 trial evaluating the efficacy and safety of darolutamide, a novel hormonal therapy, plus ADT (antiandrogen therapy) plus docetaxel versus placebo plus ADT plus docetaxel in patients with metastatic castration-sensitive prostate cancer. Randomization was stratified by the extent of disease and alkaline phosphatase levels, below versus upper limit of normal or above. It is important to know that this study only included patients that were eligible for ADT and docetaxel chemotherapy, to begin with. The primary endpoint was overall survival with multiple secondary endpoints, including time to CRPC (castration-resistant prostate cancer), time to pain progression, time to first symptomatic skeletal event, and time to start off the next anti-neoplastic therapy, and safety. A total of 1,306 patients were randomly assigned to triplet therapy with darolutamide plus ADT plus docetaxel versus placebo plus ADT plus docetaxel. Baseline characteristics were well balanced between the treatment arms. Analysis of the primary endpoint was pre-specified. After, 533 events had occurred results show the primary endpoint of this study was met with a significant improvement in overall survival and a 32.5% reduction in risk of death for patients on the triplet therapy on for darolutamide plus ADT plus docetaxel versus placebo plus ADT plus docetaxel. It is important to know that the triplet therapy improved overall survival, despite 76% of patients in the control arm having received the next life-prolonging therapy. Subgroup analysis indicates consistent benefit across the 3 specified groups. Secondary endpoints also were favored by the triplet therapy combination over the control arm. While this study offers an additional excellent option for our patients with metastatic cancer-sensitive prostate cancer in older populations, the use of docetaxel may be a significant limitation to this triplet combination. In addition, and importantly, this study did not answer the question of whether adding docetaxel chemotherapy to the ADT plus novel hormonal therapy backbone will also improve survival. With the advent of multiple doublets and triplet combinations in recent years, as we saw in the form of ADT plus enzalutamide ADT plus apalutamide in the recent years, it is very important to find biomarkers that may predict response to these treatment options, which will allow personalization of therapy with that. I would like to conclude this podcast on the ARASENS trial. Thank you very much for your kind attention.

Dr. Neeraj Agarwal, ASCO Daily News editor-in-chief, and director of the Genitourinary Cancers Program at the University of Utah's Huntsman Cancer Institute, shares key takeaways from the PROpel and MAGNITUDE trials in mCRPC, featured at the 2022 ASCO Genitourinary Cancers Symposium.   Transcript: ASCO Daily News: Hello and welcome to the ASCO Daily News Podcast. I'm Geraldine Carroll, a reporter for the ASCO Daily News. Today, in our continuing coverage of the 2022 ASCO Genitourinary (GU) Cancers Symposium, Dr. Neeraj Agarwal, the editor-in-chief of the ASCO Daily News will highlight promising advances in metastatic castration-resistant prostate cancer. Dr. Agarwal has no conflicts relating to the topic of this episode, and his full disclosures are available in the show notes. Disclosures of all guests on the podcast can be found in our transcripts at asco.org/podcasts.   Dr. Neeraj Agarwal: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Neeraj Agarwal, the director of the Genitourinary Cancer Program, and professor of medicine at the University of Utah Huntsman Cancer Institute, and editor in chief of the ASCO Daily News. I'd like to start with the PROpel trial followed by a discussion on the MAGNITUDE trial. So, Abstract 11 was on the results of the PROpel trial and presented by Dr. Fred Saad from the University of Montreal. PROpel is a randomized phase 3 trial, which evaluated the efficacy and safety of olaparib, a PARP inhibitor plus abiraterone versus this placebo plus abiraterone in the first-line metastatic castration-resistant prostate cancer setting. Patients were allowed to have docetaxel chemotherapy is given in a metastatic castration-sensitive prostate cancer setting. Enrollment in the study was independent of the effects in the homologous recombination repair pathway. The primary endpoint was investigator-assessed radiographic progression-free survival (PFS) with multiple secondary endpoints, including overall survival and safety.   Approximately 800 patients were randomly assigned to the novel combination of olaparib plus abiraterone or placebo plus abiraterone. Baseline characteristics were well-balanced between the treatment arms, including homologous recombination repair or HRR mutation status. At the pre-planned interim analysis results show the trial meets its primary endpoint with significant improvement in radiographic PFS for all patients receiving the combination therapy versus control, regardless of the presence of homologous recombination repair gene mutations. Median PFS was 24.8 months versus 16.6 months for patients receiving olaparib plus abiraterone versus placebo plus abiraterone respectively with the hazard ratio of 0.66, and a P < 0.0001. This translates into a 34% reduction in risk of progression or death. Overall survival results are still immature with only 29% [of patients experiencing events] thus far. It is interesting that even patients deemed negative for homologous recombination repair gene mutations showed significant improvement in radiographic PFS when treated with the combination of olaparib plus abiraterone versus placebo plus abiraterone.   Regarding the adverse effects, they were what you would expect from the combination of a PARP inhibitor, such as olaparib and abiraterone. We saw a higher sequence of all great events of anemia, fatigue, and nausea in the combination arm. While anemia was the only grade 3-4 adverse event observed at a significantly high frequency in the combination arm. It is also important [that] we get a better understanding of the molecular mechanism by which patients who are homologous recombination repair mutation-negative are benefiting from the combination treatment as well.   The next trial in this context, or this team, was the MAGNITUDE trial. Abstract 12 was presented by Dr. Kim Chi from British Columbia Cancer Center in Vancouver, Canada. MAGNITUDE is a randomized phase 3 trial evaluating the efficacy and safety of niraparib plus abiraterone plus placebo plus abiraterone in the first-line metastatic castration-resistant prostate cancer setting. The study population was slightly different from what we saw in PROpel trial. Taxane chemotherapy, as well as novel hormonal therapy, was allowed in metastatic castration-sensitive prostate cancer, as well as a prior novel hormonal therapy was allowed in the non-metastatic castration-resistant prostate cancer.   Also, patients were allowed up to 4 months of treatment with abiraterone in the first-line metastatic castrate-resistant prostate cancer. Prospective selection of patients with, and without homologous recombination repair (HRR) gene mutations were required. The primary endpoint was radiographic PFS by central review with multiple secondary endpoints, including overall survival and safety. A pre-specified fertility analysis was planned after enrolling 233 patients who were randomly assigned to niraparib plus abiraterone or placebo plus abiraterone. Evaluation of fertility was based on the composite PFS of PSA or radiographic progression, whichever occurred first. The pre-planned fertility analysis showed no benefit in the biomarker negative cohort. And thus the trial did not pursue further enrollment of those patients who were not positive for homologous recombination repair gene mutations.   Coming to the HRR positive cohort, 423 patients were randomly assigned to either niraparib plus abiraterone or placebo plus abiraterone. At the pre-planned interim analysis primary endpoint was met with a significant improvement in radiographic PFS for BRCA1 and BRCA2 and all patients who are homologous recombination repair mutation-positive, receiving the novel combination of niraparib plus abiraterone. Overall survival results are still immature. It is important to note that in the patients who are HRR positive, approximately 50% were BRCA1 and 2 positive. And these patients clearly derived the most benefit with a combination with an approximate 47% reduced risk of death. And if you look at other patients who are biomarker positive, there was a clear benefit and a significant improvement in median PFS (radiographic progression-free survival) with a hazard ratio of 0.73, which translates to a 27% reduction in the risk of death or progression. With the caveat of subgroup analysis, being underpowered following groups of patients seem to derive less benefit with the combination than the overall cohort with the combination of niraparib plus abiraterone. And these patients included patients who were age 65 or younger, or less than age 65, patients with visceral metastatic disease, patients with prior abiraterone or taxane chemotherapy, [and] patients who had a PSL level below the median, and patients with non-BRCA homologous recombination repair mutations.   In conclusion, the combination of niraparib plus abiraterone shows a significant improvement in the radiographic PFS for patients who are HRR positive in the first-line metastatic CRPC. Based on the available data in the public domain, without any doubt that both PROpel and MAGNITUDE trials established a combination of a PARP inhibitor with abiraterone in the first-line metastatic CRPC setting for patients who are positive for HRR mutation improve radiographic progression-free survival. Even though overall survival data are immature for both trials, I expect both combinations will be approved by the U.S. Food and Drug Administration in the near future and will be available to our patients. Regarding the HRR negative cohort in the PROpel trial, which also seems to derive significant benefit with the combination of abiraterone plus olaparib, I'm looking forward to the data on confirmation of HRR negative status by tissue-based genomic profiling results in the full-length publication which we expect to be published soon. If indeed confirmed by the tissue-based genomic profiling, I see the combination of abiraterone plus olaparib to be a reasonable option in the patients who are HRR negative in the first-line metastatic CRPC setting.   With this, I would like to conclude my discussion on the 2 practice-changing trials presented in the 2022 ASCO GU meeting, which were the PROpel and MAGNITUDE trials.
