Andrews, et al. published on June 07, 2024. Transcript The guest on this podcast episode has no disclosures to declare. Jiasen He: Hello and welcome to the JCO Precision Oncology Article Insights. I'm your host, Jiasen, and today we'll be discussing the JCO Precision Oncology article, "Predictive Impact of Tumor Mutational Burden on Real-World Outcomes of First-Line Immune Checkpoint Inhibition in Metastatic Melanoma," by Dr. Miles C. Andrews and colleagues. This study was supported by Foundation Medicine, a for-profit company that conducts FDA-regulated molecular diagnostics, including assays used to measure tumor mutational burdens, or TMB, as described in this article. Immune checkpoint inhibitor (ICI) therapy has become a cornerstone in the treatment of metastatic melanoma. They work by activating the patient's own immune system, representing a fundamentally different approach from traditional chemotherapy. Several biomarkers have emerged as promising tools to predict ICI therapy response, and TMB is one of the most extensively studied. TMB is defined as the number of somatic mutations per megabase of an interrogated genome sequence. In the KEYNOTE-158 study, patients with high TMB showed better response rates and longer progression-free survival compared to those with low TMB, which led to the FDA tumor-agnostic approval of TMB as a biomarker to guide ICI therapy. In this manuscript, Dr. Andrews and colleagues set out to answer an important question: does TMB predict outcomes of ICI therapy in real-world patients with advanced melanoma? To explore this, they analyzed de-identified data from the nationwide Flatiron Health-Foundation Medicine Clinico-Genomic Database (CGDB). To be included, patients needed to have had at least two visits to a Flatiron Health clinic and a Foundation Medicine Comprehensive Genomic Profiling report. Eligible patients had received first-line treatment with either monotherapy (nivolumab or pembrolizumab) or dual therapy with the combination of ipilimumab and nivolumab for metastatic melanoma. They also needed a tissue-based TMB score from either the FoundationOne or FoundationOne CDx genomic test. For this study, TMB less than 10 mutations per megabase was considered low TMB; TMB equal to or more than 10 mutations per megabase was considered high TMB; and TMB equal to or more than 20 mutations per megabase was considered very high TMB. Of the 497 patients in the final cohort, 29% had low TMB, while 71% had high TMB, and 50% had very high TMB. The authors observed that patients with very high TMB were more often male, had BRAF wild-type tumors, and were more likely to receive anti-PD-1 monotherapy. This group also had tumors more commonly sampled from brain and lung metastases. Patients with high TMB but not very high TMB were more likely to carry the BRAF V600K mutation and were least likely to have lung metastases. Meanwhile, those with low TMB tended to be younger and had disease limited to non-visceral sites. As expected, the presence of ultraviolet mutation signatures, a known driver of melanoma, was strongly associated with TMB. UV signatures were found in just 18% of the low TMB group, but in 89% of the high TMB and 93% of the very high TMB group. High TMB was found to be prognostic of improved real-world progression-free survival (PFS) and overall survival (OS) in patients receiving both monotherapy and dual immune checkpoint inhibitors, even after adjusting for other established prognostic factors. Interestingly, in the low TMB group, overall survival was likely confounded by the availability of effective second-line targeted therapy, particularly for BRAF-mutant patients. These patients had better outcomes compared to their BRAF wild-type counterparts, likely reflecting a greater reliance on salvage therapy in low TMB patients who derived less benefit from first-line immunotherapy. The authors then further examined the ICI outcomes using stepwise TMB thresholds, with TMB less than 10 as low, 10 to 19 as high, and equal to or more than 20 as very high. For those receiving ICI monotherapy, both PFS and OS were highest in the very high TMB group, followed by the high TMB group, and lowest in the low TMB group. However, in patients treated with dual ICI therapy, the results diverged. While low TMB patients still had the poorest outcomes, those with high TMB (mutations 10 to 19 per megabase) had better PFS and overall survival than those with very high TMB (mutations equal to or more than 20 per megabase). The authors then conducted exploratory multivariable modeling, showing that among very high TMB patients with BRAF mutations, dual ICI therapy was associated with a significantly higher hazard ratio compared to monotherapy. They concluded that dual ICI may not benefit, and could even harm, patients with very high TMB, whereas those with TMB between 10 and 20 mutations per megabase may get more from the intensified regimen. Importantly, as the authors stated in the manuscript, we need to note that in this cohort, very high TMB patients were more likely to have brain metastases at treatment initiation, be male, and lack BRAF V600E/K mutations—all factors associated with poorer prognosis. This might partially explain inferior outcomes to dual ICI in very high TMB patients, as patients were not randomly assigned to therapy in this retrospective, real-world study. As such, these findings should be interpreted with caution and validated in future studies. In summary, this study showed that in a real-world setting, high tumor mutational burden predicts better outcomes with immune checkpoint inhibitor therapy in patients with advanced melanoma. Interestingly, the authors found that dual ICI therapy may offer no added benefit for patients with very high TMB compared to ICI monotherapy. However, this was a retrospective, non-randomized study, and the cohorts were imbalanced for some known risk factors, which could confound outcomes. As a result, these findings should be interpreted with caution and will need to be validated in future prospective studies. Thank you for tuning into JCO Precision Oncology Article Insights.

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. Peter, thank you for sharing your insights with us today.

JCO PO author Dr. Hatim Husain at University of California San Diego, shares insights into his JCO PO article, “Adagrasib Treatment After Sotorasib-Related Hepatotoxicity in Patients With KRASG12C-Mutated Non–Small Cell Lung Cancer: A Case Series and Literature Review”, one of the top downloaded articles of 2024. Host Dr. Rafeh Naqash and Dr. Husain discuss how to utilize real-world and clinical trial data to discern the safety of adagrasib (another KRASG12C inhibitor), following sotorasib discontinuation due to hepatotoxicity. TRANSCRIPT Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations where we bring you engaging conversations with authors of clinically relevant and highly significant JCOPO articles. I'm your host, Dr. Rafeh Naqash, Podcast Editor for JCO Precision Oncology and Assistant Professor at the OU Stephenson Cancer Center.  Today, I'm very excited to be joined by Dr. Hatim Hussain, Professor of Medicine at the University of California, San Diego, and author of the JCO Precision Oncology article, “Adagrasib Treatment After Sotorasib-Related Hepatotoxicity in Patients With KRAS-G12C-Mutated Non-Small Cell Lung Cancer: A Case Series and Literature Review.” This was one of the top downloaded articles of 2024. And the other interesting thing is we generally don't do podcasts for case reports or case series, so this is one of the very few that we have selected for the podcast.  And at the time of the recording, our guest disclosures will be linked in the transcript.  Dr. Hussain, welcome to our podcast and thank you for joining us today. Dr. Hatim Husain: Thank you Dr. Naqash. Such a pleasure to be here and to speak with you all. Dr. Rafeh Naqash: And for the sake of this podcast, we'll refer to each other using our first names. So again, as I mentioned earlier that this is one of the very few case reports that we have selected for podcasts in JCOPO and the intention was very deliberate because it caters to something that is emerging where we are trying to treat more KRAS mutant patients with different KRAS inhibitors. And you tried to address one very unique aspect of it in this article which pertains to toxicity, especially hepatotoxicity. So for the sake of our listeners who tend to be community oncologists, trainees, academic faculty, can you tell us what are KRAS inhibitors? What is KRAS-G12C? And how do some of these approved KRAS inhibitors try to inhibit KRAS-G12C? Dr. Hatim Husain: Sure. For a long time actually we've not had a selective way to inhibit mutant KRAS. And over the last several years actually now, we've seen some dramatic advances here, particularly with the FDA approval of some of the selective inhibitors against the G12C variant. So KRAS-G12C is an isoform of KRAS that is most common in lung cancer and in fact actually is a transversion mutation in the KRAS gene that is a product of the carcinogen of tobacco. And in fact, the incidence of KRAS-G12C in lung cancer, it's quite astounding where as many KRAS-G12C patients there are, there can be, as you know, more than EGFR patients in certain populations and cohorts. The medicines sotorasib and adagrasib were rationally designed to be selective KRAS-G12C inhibitors. And the way that they do this is that they lock the KRAS protein in the OFF state. KRAS is a protein that oscillates between an ON and an OFF state and by virtue of locking the protein in an OFF state, it has shown inhibition of downstream signaling and mitigation of tumor growth and, in fact, tumor cell death. Dr. Rafeh Naqash: I absolutely love the way you describe the ON and OFF state, the oscillation where the ON is bound to the GTP and the OFF is bound to the GDP. The two KRAS inhibitors as currently FDA approved, as you mentioned, are RAS OFF inhibitors and they're emerging KRAS inhibitors that are RAS ON. So now, as we have known from previous data related to immunotherapy and EGFR TKIs such as osimirtinib where toxicity tends to be a compounded effect when you have osimertinib given within a certain timeline of previous checkpoint therapy, we've seen that in the clinic as the data for these KRAS inhibitors is emerging, you talk about some very interesting aspects and data about what has been published so far with regards to prior use of immunotherapy or chemo immunotherapy and the subsequent use of KRAS inhibitors. Could you elaborate upon that? Dr. Hatim Husain: Sure. So for this population of patients, the first line approved strategy is a strategy that most cases will incorporate immune therapy and chemotherapy. Immune therapy can have some important responses for patients with KRAS-G12C. This may be due to the fact that KRAS-G12C patients may have a higher incidence of prior smoking, perhaps higher mutation burdens in some patients, and perhaps immunogenicity is defined in that context. So the standard of care in the first line currently includes immune therapy or immune therapy and chemotherapy. Where the current FDA approvals for selective G12C inhibitors are are after the first line of therapy. There are a number of trials exploring these medicines in the first line to see if they may be incorporated into a future treatment paradigm. Dr. Rafeh Naqash: Thank you for that explanation. Now, going to what you published in this manuscript, can you help us understand the context of why you looked at this? Even though the data just comprises a case series of a handful of patients, but the observations are very interesting and these are real world scenarios where we often tend to be in situations where an individual has had toxicity on a certain drug and may have some response to that drug, but at the same time, the toxicity is challenging. And then you try to debate whether another drug in the same class might be beneficial without those toxicities. So you've tried to address that to some extent using this data set. So can you elaborate upon the question, the methodology, what you tried to look at, and important observations that you have? Dr. Hatim Husain: Yes, our paper was actually inspired by one of my patients. My patient was a patient who had received chemotherapy and immune therapy and actually in the past, even, you know, additional lines of immune therapies, it was really coming to the edge of where standard treatments would exist. It was right at the same time that these selective inhibitors had been approved and the patient had received sotorasib. And what was remarkable was, when given sotorasib, patient had a very high peak and spike in the transaminases. And we would do different trials of strategies around dose, around interruptions. And it was becoming quite difficult, actually, for the patient to proceed with additional therapy. It was around similar times, actually, and I do want to make a note that the patient was progressing, driven in large fact by the fact that we've had to interrupt the medicine. So we feel and believe that the patient had had inadequate dosing because of the level of toxicity that the patient was having with transaminase increase. So it was around the same time that adagrasib was first commercially available that we were at that point, and we did a trial of adagrasib post-sotorasib, largely driven by necessity, without having additional options to provide this patient in our environment. What was remarkable was when the patient received the adagrasib, there were no spikes in transaminases similar to what we had seen before. And that really led us thinking and to say, “Is this adverse event of transaminase increase or hepatotoxicity, is this a class effect with KRAS-G12C inhibitors, or is it more nuanced than that? Are there different, perhaps, mechanisms by which the medicines may work that may more or less differentially contribute to this adverse event?” And so that inspired us to kind of do a larger analysis, kind of really reach out to a larger network of physicians to gather insights and to gather responses in patients who had had a serial approach of sotorasib and then adagrasib.  What we found in this process was, in fact, actually there were many more cases of patients who resembled my patient, where the sequence of sotorasib going to adagrasib may have demonstrated differential contribution of hepatotoxicity in that context. And that really motivated us to put the publication together to due diligence, and in the publication spend a lot of time to kind of outline each patient case in detail around metrics surrounding time from last immune therapy, the number of days on sotorasib, the best response to sotorasib, the interval between sotorasib and adagrasib, the duration of adagrasib and then the grade of hepatotoxicity seen in each of the contexts, and particularly kind of the adagrasib and patient disease status as well. We were quite inspired by the effort to try to, if we do not have randomized data in comparison of one medicine to another, which we do not at this juncture, we do not have a randomized analysis to really diligently and rigorously compare the rates of AEs across each medicine, and even in sequence, we do not have that with immune therapy. But what we felt was trying to get more analysis of this sequential approach of, if patients had received a medicine, had to be taken off because of toxicity and then actually tried on a new medicine, what were those rates? We felt like that was at least some information to try to get at this question. Dr. Rafeh Naqash: And you bring forward a very important point, which is, a lot of times in the real world setting we don't have cross trial comparisons that can be fully applicable, or we don't have trials that compare two drugs of the same class with respect to the AE profile or efficacy. And observations like the one that you described that led to this study are extremely critical in trying to help answer these questions.  From a data standpoint, and you allude to it to some extent in your manuscript, the trials that are trying to address combination of KRAS-G12C with immunotherapy, especially sotorasib or adagrasib, can you elaborate on that data, what has been published so far and summarize it for our listeners? Dr. Hatim Husain: So there is data from clinical trials looking at patients actually who have received concomitant immune therapy and sotorasib. What was seen in this, in a real world analysis, was that some patients actually who had received sotorasib within a close proximity of immune therapy, as well as a larger study actually which showed in combination there were higher rates of hepatotoxicity in that context. In fact, there were rates of grade 3 hepatotoxicity. And I think built upon that data there's a recognition in the field that we have to be very diligent in terms of even the clinical trial designs in how to understand the pairing between immune therapy and selective G12C inhibitors. There are many trials that are ongoing, one of the studies that is ongoing is known as the KRYSTAL-7 study, which is evaluating adagrasib in combination with pembrolizumab in the first line. And we await more information on that strategy as well. In the context of sotorasib, because of some of the trials that have shown higher rates of hepatotoxicity, there are some additional trials now looking at sotorasib in combination with chemotherapy, and those also have some information that have been reported as well. Dr. Rafeh Naqash: From a drug development standpoint, as you mentioned, there's always a tendency to combine something with something else. And in my practice, and I'm sure in your practice too, when we do early phase trials, many trials are still focused on choosing the maximum tolerated dose, which may be something that we need to gradually move away from as we try to implement these combinations of multiple antibodies plus some of these target agents from maybe the biological optimal dose rather than the maximal tolerant dose is a better way to look at the drugs, the pharmacokinetic profile, and then see what is likely the safest combination with the most appropriate target engagement. Do you have any thoughts on that or insights on that from a drug development perspective? Dr. Hatim Husain: It's a wonderful question and I think it is a very insightful question and understanding of where we are in space right now. And I agree with you that historically, cancer drug development was really hinged upon medicines that perhaps required higher doses to see a benefit or to inch out kind of marginal increases upon where we were at. Now, in combination with medicines that have non-overlapping mechanisms of action, the concept is: Can there actually be more synergy across an approach using combinatorial strategies rather than just additive effects? And I think that in some cases this is being studied with immune therapy, in some cases actually even in the context of other novel mechanisms for cancer therapy. I think that in my practice, I will really try to see how a patient at an approved dose will respond. But definitely I'm open to the concept that there may be a dose that doesn't have to be the maximally tolerated dose, but rather the dose that responses can be seen and perhaps actually at a lower dose than what drives many toxicities. Dr. Rafeh Naqash: I often describe this to my patients as individual patient dose optimization outside of a clinical trial, where I'm sure you've probably done this, where in older adults maybe a lower dose of osimertinib is tolerated better, or a lower dose of sotorasib or adagrasib for that matter, tolerated better with perhaps a similar level of efficacy, since we don't have comparisons between doses and efficacy so far.  So I think in the bigger picture, as we discussed in a nutshell, what I would really like the listeners to understand is as we try to move towards this field of precision medicine targeting more and more of the undruggable genes, there's bound to be a certain level of toxicity patterns that we'll start observing. So I think these real world scenarios which may not be addressed using clinical trials because it is in the real world setting where you cycle one treatment after another after another, which may or may not be allowed in most trials and the real world setting can inform, in certain cases, subsequent trial designs. So I think the most important message, at least that I took from your manuscript, was that these real world observations can make a huge difference and inform practice, even though the data sets may be small. Of course, you want to validate some of these findings in a bigger, broader setting, but proof of concept is there. And I think next time I see an individual in my clinic where I see better toxicity, I'll definitely try to talk to them about subsequent treatment with another KRAS inhibitor, maybe adagrasib or something else, if and when appropriate.  Do you have any closing thoughts on some of these things that we discussed? Dr. Hatim Husain: I just want to leave the audience actually with this concept that sometimes we group targeted therapy side effects as being class effects unanimously. And I do think actually that each inhibitor may have different off target effects on where medicine may act. We don't truly understand the mechanism of hepatotoxicity in the context of selective KRAS-G12C inhibitors. One of the hypotheses may be due to off target cysteine reactivity in the numerous off target binding sites that certain medicines may have over others. And just even qualitatively which off target binding sites there may be, and how that may lead to either immunogenic responses and other organs or such. So I do think that we do need more research to understand the mechanism. But I think where we are at right now in this space is not assuming that all medicines are going to have the exact same toxicity. I think especially when patients may not have other options, this is something to consider as well. Dr. Rafeh Naqash: Thank you so much. Now, outside of the scientific insights, Hatim, I know you a little bit from before. And knowing the kind of work that you've done in precision medicine, I'm really interested to know about where you started, how you started, how things have been, and what kind of advice you have for junior faculty fellows who are interested in this field of precision medicine that is becoming more and more exciting as we progress in the oncology space. Dr. Hatim Husain: Thank you, Rafeh. I will say, actually as a medical student, I was actually very interested in oncology, partly because it was then and still remains one disease or a constellation of diseases that just has such a high psychological burden on patients. And through the experiences I've had, I really can understand and relate with that concept. I did my medical school at Northwestern, residency at the University of Southern California, and then my oncology fellowship at Johns Hopkins University.  And now I've been on faculty at University of California, San Diego, for about 12 years now. It's been a great experience paralleled with the fact that during these last 12 years, I've really seen how the developments in precision oncology, both targeted therapy as well as immune therapy, have really blossomed and unfolded. A large area of my research in my career has kind of focused on cancer genome and integration of novel technologies to really see how they may have clinical application. When I was in my fellowship and as a young faculty, the liquid biopsy was actually coming into development. And this was hinged upon information that had come forward in the prenatal space where some patients actually who were undergoing prenatal testing during pregnancy were found to have complex karyotypes and genomic alterations and then retrospectively found to have cancer.  And doing my fellowship at Johns Hopkins, some of the pioneers in liquid biopsy were my mentors and really kind of instilled in me that passion for really thinking through how cancer genomics can be integrated through time. And some of the research that I have been doing has been looking at clonal evolution of cancer, how cancer is changing over time, and how we can think through the right surveillance strategies to really understand how that change is occurring. The dynamics of ctDNA in retrospective cohorts have been studied and shown that, you know, there can be associations between progression-free survival and other clinical endpoints. The current paper that we are speaking about parallels that in a certain way where, rather than say, looking at clonal evolution and say, the efficacy answer of sotorasib first and then adagrasib and how frequently can adagrasib salvage patients, this looks at it from a different angle around toxicity. And I think that is a key point because, at my core, I really do enjoy the clinical aspect of complex decision making on behalf of patients weighing efficacy and toxicity that they may have as they try to get the best quality of life through this journey.

Dr. Shaalan Beg and Dr. David Wang discuss key abstracts in GI cancers from the 2025 ASCO Gastrointestinal Cancers Symposium, including major advances in CRC, neoadjuvant approaches in esophageal cancer, and innovative studies on ctDNA. TRANSCRIPT Dr. Shaalan Beg: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Shaalan Beg. I'm a medical oncologist and an adjunct associate professor at UT Southwestern Medical Center in Dallas. Today, we're bringing you some key highlights from the 2025 ASCO Gastrointestinal Cancers Symposium, and I'm delighted to be joined by the chair of GI25, Dr. David Wang. Dr. Wang is a GI medical oncologist at the University of Michigan. Our full disclosures are available in the transcript of this episode.  Dr. Wang, thanks for coming on the podcast today. Dr. David Wang: Well, thank you. It's a pleasure to be here. Dr. Shaalan Beg: GI25 featured major therapeutic advances across the spectrum of GI malignancies, and it was exciting to hear about innovations and novel approaches that are shaping the future of our field. Before we start talking about specific abstracts, could you share some of your key highlights from the meeting? Dr. David Wang: Sure. Our theme this year was “Breaking Boundaries to Enhance Patient Centered Care.” Past years' themes have focused more on precision oncology, but we wanted to broaden our focus on patients and to be more holistic, which kind of led us into some of the Intersection [sessions] that we had. Each day started with a different Intersection. The first one was “Emerging Therapies in GI Cancers”, where invited speakers talked about bispecific antibody drug conjugates, theranostics, CAR T and other cell-based therapies. The second day was on “Personalized Risk Assessment for GI Cancers,” and this included looking at polygenic risk scores for colorectal cancer, microRNAs and liquid biopsies such as exosomes and pancreatic cancer and non-endoscopic screening modalities in esophageal cancer. And on our final day, we wanted to talk about “Integrative Oncology and Integrative Medicine,” looking at evidence-based uses of acupuncture and supplements in patients who are receiving treatment for cancer, mindfulness-based practices and exercise. And of course, we had a fantastic keynote talk by Dr. Pamela Kunz from the Yale School of Medicine titled, “Disrupting Gastrointestinal Oncology: Shattering Barriers with Inclusive Science.” She highlighted the intersection of science, patient care, and health and gender equity. And I would encourage your podcast listeners to access the lecture in ASCO's Meeting Library if they haven't yet had a chance to hear Dr. Kunz's wonderful lecture.  We were really happy this year because the attendance hit a new record. We had over 5,000 people attend either in person or virtually from their home or office, and we had almost 1,000 abstracts submitted to the meeting, so these were either record or near record numbers. We offered a lot of different networking opportunities throughout the meeting, and attending found these to be incredibly rewarding and important and this will continue to be an area of emphasis in future meetings. Dr. Shaalan Beg: Let's take a deeper dive into the exciting studies presented at GI25. The late breaking abstract LBA143 was CheckMate-8HW. This was the first results of NIVO + IPI versus NIVO monotherapy for MSI-high metastatic colorectal cancer. What are your thoughts about this study? Dr. David Wang: Yeah, so we know that colorectal cancer patients with MSI-high tumors don't necessarily respond well to chemotherapy. And we were fortunate because last year CheckMate-8HW actually looked at two different arms – so this was NIVO + IPI compared to standard of care chemotherapy and showed its very significant improvement in median progression-free survival. And that was actually published in the New England Journal of Medicine back in November of 2024. This year's presentation actually focused now on NIVO + IPI versus NIVO monotherapy. And as you know IPI+NIVO can be quite toxic. So this was an important analysis to be done. So we know that NIVO is definitely more easily tolerated. So what was interesting was that the 2-year and 3-year progression-free survival not surprisingly favored IPI+NIVO and this was statistically significant. And the overall response rate was also better with IPI+NIVO versus NIVO alone. I know we're always concerned about toxicities and there were higher grade 3 and 4 toxicity incidences in the combination arm versus the monotherapy arm, but overall, only about 28 additional events in several hundred patients treated. So I think that's well-tolerated. Our discussant Dr. Wells Messersmith actually said that, with this new data, he would consider doing combination immunotherapy in any patient that presented in the front line with MSI-high or deficient mismatch repair colorectal cancer that was metastatic. Dr. Shaalan Beg: One of the focuses for directing first-line therapy for colorectal cancer has been right and left sided colon cancer because we know these are two different cancers with their own unique molecular subtypes. We heard on Abstract 17, the DEEPER trial, the final analysis of modified FOLFOXIRI plus cetuximab versus bevacizumab for RAS wild-type and left sided metastatic colorectal cancer. How do you summarize the findings of this study and what should our readers be aware of? Dr. David Wang: Interestingly, this was a phase 2 study and the emphasis of the abstract was actually a subgroup analysis of those patients with RAS wild-type and BRAF wild-type as well as left sided cancers. So, I think the entire study enrolled 359 patients, but the analysis that was discussed at the meeting really focused on 178 patients that fit that characteristic. Very similar to what we've seen in prior studies, left-sided tumors have better response to cetuximab versus bevacizumab. And if you flip it so that you now are looking at right sided tumors, targeting EGFR is actually detrimental. The depth of response was better with cetuximab in these left sided RAS and BRAF mutant tumors. And so the lead author actually suggested that this could be a new first-line standard of care. And the question is, is there a benefit of doing this triple agent regimen with modified FOLFIRINOX? We know there's a lot more toxicity with that. Not clear that there's a benefit for that over FOLFOX, maybe in younger patients that could tolerate it. When our discussant, again Dr. Wells Messersmith, spoke about this, he said that, in his practice he would, again, favor cetuximab over bevacizumab in combination with chemo, these left-sided RAS and BRAF wild-type tumors, but that he would actually prefer a doublet versus a triplet chemo regimen, and that is consistent with the current NCCN guidelines. Dr. Shaalan Beg: Another area where colorectal cancer has been a wonderful model to study new technology has been in the area of circulating tumor DNA (ctDNA). And the BESPOKE CRC trial is looking to see if ctDNA can inform adjuvant treatment decisions for stage II and III colorectal cancer. And in Abstract 15, we heard final results of the BESPOKE CRC sub-cohort. What were the findings there? Dr. David Wang: BESPOKE CRC is another one of these important ctDNA studies. It was an observational study, not a randomized trial, but it did provide a lot of different insights to us. We know that there were over 1,700 patients enrolled, and so it was reported that this is the largest ctDNA study in colorectal cancer performed in the United States. And they were able to analyze over 1,100 patients.  Some of the key findings were that postoperative adjuvant therapy management decisions actually changed in 1 out of 6 patients, so that's pretty significant. In terms of surveillance, we know that patients who have ctDNA positivity, this is prognostic of recurrence. In terms of patients who have positive ctDNA post-surgery, it looked like, at least in this observational study, the majority of patients who received any benefit were those who had positive ctDNA. So adjuvant therapy, even in stage II and stage III patients seemed to only benefit those patients who have positive ctDNA. I think that does raise the question, and this also was brought up in the discussion, which is “Can we de-escalate adjuvant therapy in terms of patients who are ctDNA-negative post-op?” And Dr. Richard Kim from Moffitt felt that we are not yet there. Obviously, we need randomized control trials where we are taking ctDNA results and then randomizing patients to receive adjuvant or non-adjuvant to really know the difference.  Other questions that come up with use of ctDNA include: What do you do with these patients who turn positive? This study for BESPOKE actually followed patients out to two years after surgery. So what you do with a positive ctDNA result wasn't really clear. It seems to suggest that once you turn positive, patients go on to more intensive surveillance. You know, again as an observation, patients who did turn positive were able to go to metastasis-directed therapy much more quickly. And again, this was supposedly to improve their curative intent therapy. And I think the other question that has been brought up all the time is, is this really cost effective? Patients want to know, and we want to give patients that information, but I think we're still stuck with what to do with a positive ctDNA level in a patient that's on surveillance because no randomized control studies have actually suggested that we need to start systemic therapy right away. Dr. Shaalan Beg: Yeah. And I guess in terms of practice informing or practice changing, these results may not give us a clear answer. But because a lot of patients are asking for these tests, it does give us some real world experiences on what to expect in terms of conversion of these positive into negative and the outcome so we can have a shared decision making with our patients in the clinic and then come up with a determination on whether ctDNA for molecular residual disease is something which would be worthwhile for the care of our patient. But more to come, I guess, in coming years to answer different problems around this challenge. Dr. David Wang: Yes, I agree. Dr. Shaalan Beg: The BREAKWATER trial looked at the use of encorafenib, cetuximab and chemotherapy for BRAF V600E-mutant metastatic colorectal cancer. We've covered this combination for a second- third-line treatment in metastatic colorectal cancer previously. Abstract 16 from GI25 was evaluating the use of this regimen in the first-line space. Everyone was looking forward to these results, and what did the investigators present? Dr. David Wang: I think this is, as you mentioned, a nice follow up to later lines of therapy where Dr. Kopetz from MD Anderson pioneered use of encorafenib, cetuximab and binimetinib in the BEACON trial. Everybody was kind of curious what would happen now if you use encorafenib plus cetuximab plus chemotherapy in the first-line setting. And so this is an interim analysis that was pre-planned in the phase 3 open label BREAKWATER trial. And even though there were three arms, and so the three arms were encorafenib plus cetuximab, encorafenib plus cetuximab plus FOLFOX, or standard of care chemo, only two arms were presented in the abstract. So basically looking at encorafenib plus cetuximab and FOLFOX-6 versus standard of care therapy, and the overall response rate was statistically significant with a 60.9% overall response rate encorafenib plus cetuximab plus chemo arm versus standard of care chemo was only 40%. The interim overall survival also was different. It was 92% versus 87% at 6 months and 79% versus 66% at 12 months, again favoring the chemotherapy plus encorafenib plus cetuximab. In terms of the statistics, the p was 0.0004. However, the pre-plan analysis required the p-value to be 1x10 to the -8. And so even though this looks really good, it hasn't quite met its pre-specified significance level. The good thing is that this is only interim analysis and the study is ongoing with future analysis planned.  So the real question is: Does it matter when we actually use this regimen? We know that the regimen's approved in the second third-line setting. What about in the first line? And there was some preclinical data that the discussant reviewed that shows that patients actually benefit if this is done in the first-line setting. For example, there was some preclinical data showing that even FOLFIRI, for example, can upregulate RAS, which would make tumors more resistant to this combination. This was thought to be practice-changing in a patient that has B600E showing up treatment naive that we should probably consider this regimen. And actually this did receive accelerated FDA approval about a month ago. Dr. Shaalan Beg: Yeah, and for what it's worth, I put up a Twitter poll asking my Twitter followers on how the BREAKWATER trial results will change their approach for newly diagnosed BRAF mutated colorectal cancer. We got 112 responses; 72% said that they will incorporate encorafenib, cetuximab, FOLFOX for their frontline BRAF mutated patients. But 23% said that they would like to wait for overall survival results. Dr. David Wang: Wow, that's interesting. They really want that 1x10 to the -8. Dr. Shaalan Beg: I guess so. All right. Let's change gears and talk about esophageal cancer. LBA329 was the SCIENCE study which presented preliminary results from a randomized phase 3 trial comparing sintilimab and chemoradiotherapy plus sintilimab versus chemoradiotherapy for neoadjuvant resectable locally advanced squamous esophageal cancer. Where are we in this space? Dr. David Wang: Okay. So, yeah, this was an interesting trial. Again, just to set the context, esophageal squamous cell carcinoma is more prevalent in Asia. And the study sites as well as the patients were mostly from Asia. So this was again a phase 3 trial with interim results. They only rolled 146 out of the planned 420 for this interim analysis. And yeah, they're using immune checkpoint inhibitor that we don't use in the United States, sintilimab, combined with their two standards of neoadjuvant therapy, either chemotherapy, which is more common in Asia, or or chemoradiation, which is more common in the US and Western Europe, versus chemoradiation. And so they actually had two primary endpoints, but only were reporting one. So their two primary endpoints were pathCR and the other one was event-free survival. The event-free survival, again, was not reported at the meeting.  What they found was that in terms of pathCR rate, if you take the two arms that are really informative about that, chemoradiation plus sintilimab versus chemoradiation alone, the pathCR rate was 60% versus 47%. We know that chemo alone doesn't induce as much of a pathCR rate, and that was 13%. So it was found that the delta in terms of pathCR between the chemoradiation arms, one with sintilimab and one without, was significant. And this actually confirms data again from Asia, like for the ESCORT-NEO trial where it used another immune checkpoint inhibitor pembrolizumab in addition to neoadjuvant chemo.  So as our discussant for this abstract said, yes, we know that radiation combined with chemotherapy improves pathCR rates, but we have recent data from the ESOPEC trial, we don't know that that necessarily will translate to overall survival. So again, waiting for additional enrollments and longer term follow up before incorporating this into clinical care here. Dr. Shaalan Beg: So David, how do the results of the SCIENCE trial compare with our practice in the United States and ongoing studies asking questions for neoadjuvant therapy for esophageal carcinoma in the United States? Dr. David Wang: I think obviously immune checkpoint inhibitor in the new adjuvant setting is important. Jennifer Eads at UPenn is running that EA2174 which is looking at chemoradiation plus or minus nivolumab, and then in non-pathCR responders randomized to adjuvant nivolumab per CheckMate 577 or nivolumab with intensification adding ipilimumab. We know that the ESOPEC trial just came out, and was published actually during the meeting, and that really focuses on adenocarcinomas. So adenocarcinomas of the GE junction, distal esophagus, now, we would probably treat very similarly to gastric using perioperative FLOT. However, the standard in the US for esophageal squamous cell carcinoma remains neoadjuvant chemoradiation. We know that squamous cell carcinomas are more exquisitely sensitive to radiotherapy. And then obviously in those patients who don't achieve a pathologic complete response, the expectation would be that they would go on to receive nivolumab per CheckMate 577. Again, the thought is that these tumors are more sensitive to immunotherapy given their higher incidences of mutational changes. And so again, this kind of goes along with the positive results seen in the SCIENCE trial that we just discussed with sintilimab but also EFFECT-neo with pembrolizumab. Obviously, we await the results of Jennifer's trial. Dr. Shaalan Beg: And the last abstract I was hoping we could get your perspective on was Abstract 652, which is a Phase 3 study of everolimus plus lanreotide versus everolimus monotherapy for unresectable or recurrent gastroenteropancreatic neuroendocrine tumors, the STARTER-NET trial. What were the results of this study? Dr. David Wang: So, I just want to give a shout out because we did have a session at this year's GI ASCO that looked at more rare tumors. So appendiceal tumors, neuroendocrine tumors, those kinds of things. So again, I would encourage your listeners to listen to that session if they have interest in that. Another type of rare tumor was adenosquamous tumors.  But in terms of the STARTER-NET trial, this was again an interim analysis of his phase 3trial and it was looking at combining everolimus plus lanreotide versus everolimus. So we know that in pancreatic-gastric neuroendocrine tumors, if you have low Ki-67, a well differentiated tumor, that the standard of care really is a somatostatin analog, and sometimes if they're more aggressive, we kind of consider molecular targeted therapy with everolimus. This was asking the question of whether we should do the combination on the frontline. And what was interesting is in this study, the patients were actually more of a poor prognostic set. So they had Ki-67 up to 20% or these were patients that actually had multiple liver lesions. And what they found was a median for progression free survival was improved with a combination out to 29.7 months versus 11.5 months with the somatostatin analog alone, and that the overall response rate was 23% versus 8.3%, again, favoring the combination. If you looked at subgroup analysis, it was actually those patients who had Ki-67 greater than 10%, so the more aggressive tumors, or those with diffuse liver lesions that had the most benefit. So I think that would be the patient population I would consider this new combination with using would be those patients again with poorer prognosis neuroendocrine tumor phenotype.

In the previous episode we heard how some rationally-designed therapies work on almost any cancer with the right molecular signature. Tumour-agnostic medications could be godsend for patients with rare cancers which have classically been overlooked by drug developers, and those with advanced cancers of unknown origin. 15,000 such patients have undergone comprehensive genome profiling of their tumours through the organisation, Omico. In this podcast, Omico's founder explains that while the majority have received recommendations about matched therapies, clinical trials are typically the only way to enable access. Professor David Thomas discusses why Australia's Health Technology Assessment process appears to be so conservative and how the market price of next-generation oncotherapies might be brought down by changes across the local ecosystem. Guest Prof David Thomas FRACP PhD (Director, Centre for Molecular Oncology UNSW; Founder and Chief of Science, Omico)  Professor Thomas or Omico have received grants, consultancies or research support from Roche, Astra Zeneca, Pfizer, Eisai, Illumina, Beigene , Elevation Oncology, RedX Pharmaceuticals, SunPharma , Bayer, George Clinical, Novotech , Merck Sharpe and Dohme, Boehringer Ingelheim, Hummingbird, Microba , BioTessellate , PMV Pharma, Australian Unity and Foundation Medicine. ProductionProduced by Mic Cavazzini DPhil.

The genomic understanding of cancer has transformed a tissue-based classification model that had been dominant for 150 years or more. The last three decades have seen highly targeted therapies developed at blistering pace, and unprecedented improvements in patient outcomes. To date, these advances have been focused on more common cancers. The financing model for drug development means that rare cancers get overlooked, given the small pool of potential buyers relative to the costs and risks of investment. However, the molecular targets characterised in more common cancers are often found in cancers of a different histotype. As such, precision therapies will sometimes have tissue-agnostic efficacy and offer a lifeline for patients with neglected diseases or cancers of unknown origin. Professor David Thomas has founded an NGO called Omico to enable such patients to undergo profiling for hundreds of potential molecular targets. In this interview he explains the rationale for the most promising pan cancer therapies, and in the next episode we discuss changes to the regulatory and funding model required to sustain this screening program. Guest Prof David Thomas FRACP PhD (Director, Centre for Molecular Oncology UNSW; Founder and Chief of Science, Omico) Professor Thomas or Omico have received grants, consultancies or research support from Roche, Astra Zeneca, Pfizer, Eisai, Illumina, Beigene , Elevation Oncology, RedX Pharmaceuticals, SunPharma , Bayer, George Clinical, Novotech , Merck Sharpe and Dohme, Boehringer Ingelheim, Hummingbird, Microba , BioTessellate , PMV Pharma, Australian Unity and Foundation Medicine.

JCO PO author Dr. David R. Gandara at UC Davis Comprehensive Cancer Center, shares insights into his JCO PO article, “Plasma Proteome–Based Test for First-Line Treatment Selection in Metastatic Non–Small Cell Lung Cancer,” one of the Top Articles of 2024. Host Dr. Rafeh Naqash and Dr. Gandara discuss how the PROphet® blood test supports first-line immunotherapy treatment decisions for metastatic NSCLC patients. TRANSCRIPT  Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations where we bring you engaging conversations with authors of clinically relevant and highly significant JCOPO articles. I'm your host, Dr. Rafeh Naqash, Podcast Editor for JCO Precision Oncology and Assistant Professor at the OU Health Stephenson Cancer Center at the University of Oklahoma.  Today, we are absolutely thrilled to be joined by Dr. David R. Gandara, Professor of Medicine Emeritus, Co-Director of the Center for Experimental Therapeutics and Cancer and Senior Advisor to the Director at UC Davis Comprehensive Cancer Center and also the senior author of the JCO Precision Oncology article entitled “Plasma Proteome–Based Test for First-Line Treatment Selection in Metastatic Non–Small Cell Lung Cancer.” This was one of the top performing articles of 2024, which is one of the reasons why we wanted to bring it in for a podcast discussion. At the time of this recording, our guest's disclosures will be linked in the transcript.  David, it is an absolute pleasure to have you today. For somebody like you who's led the field of lung cancer over the years, I'm really excited that you are going to be talking to us about this very interesting article, especially given that I think you're one of the big proponents of liquid biopsies and plasma-based testing. So, for the sake of our listeners - which comprises of academic oncologists, community oncologists, trainees - could you tell us where the biomarker landscape for non-small cell lung cancer is currently, and then we can try to take a deeper dive into this article. Dr. David Gandar: Okay. Well, thank you, Rafeh. It's a pleasure to be with you here today. And I think the current landscape for biomarkers for immunotherapy in non-small cell lung cancer is a mess. There's no better way to describe it. That makes this paper describing a new plasma proteomic assay even more important. So I'll just give you a perspective. There are 14 trials, phase three trials, that were done in first line non-small cell lung cancer advanced stage of immunotherapy versus chemotherapy and some other aspects, although they vary tremendously. Some of them were checkpoint monotherapy, some combined with chemotherapy, some combined with CTLA-4 inhibitors and so forth. 12 out of the 14 were positive, 12 got FDA approval. So there are 12 different options that an oncologist could use. Some of them were squamous cell only, some non-squamous, some used PD-L1 as a biomarker driven part of the study. Some used TMB, tumor mutational burden, some were agnostic. So when you put all of this together, an oncologist can pick and choose among all these various regimens. And by and large, it's PD-L1 that is the therapeutic decision maker.  ASCO actually, I think, has done the very best job of making a guideline, and it's, as you well know, called a living guideline, it's dynamic. And it is much easier to interpret, for me and I think for oncologists, than some of the other guidelines. It's got a green light and a red light, it may be kind of orange. And so the green light means this is a strong recommendation by the guideline committee. The orange means it's weak. For this purpose, non-small cell lung cancer, advanced stage, only a very few of the recommendations were green. It's mainly monotherapy and patients with cancers with a PD-L1 over 50%. In our surveys, at our meetings, less than 50% of oncologists in the United States are following these guidelines. Why? Because they don't trust the biomarker. And TMB has the same sort of limitations. They're not bad biomarkers, they're incomplete. They're only looking at a part of the story. So that means we need a new biomarker. And this is one that, I think, the data are quite impressive and we'll discuss it more. Dr. Rafeh Naqash: Absolutely. Like you said, abundance of many therapy options, but not necessarily everything works the same in different subsets of PD-L1 positivity or different subsets of patients with different levels of tumor burden. And like you said, again, difficulty in trying to identify the right biomarker. And that's a nice segue to this PROphet test that you guys ran. So can you tell us a little bit about the plasma proteomic assay? Because to the best of my knowledge, there's not a lot of validated plasma proteomic assays. A lot has been done on the tumor tissue side as far as biomarkers are concerned, but not much on the blood side, except for maybe ctDNA MRD testing. So what was the background for trying to develop a plasma-based proteomic test? And then how did this idea of testing it in the lung cancer setting come into play? And then we can go into the patient population specifics, the cohort that you guys have. Dr. David Gandara: Okay. Well, of course there's a company behind this assay, it's called OncoHost, and I'm a consultant for them. And they came to me two years ago and they said, “We have something different from anyone else.” And they explained the science to me, as well as some other lung cancer experts here in the United States. I'm not a proteomic expert, of course, but they developed an AI machine learning platform to assess plasma proteins in normal people and in people with cancer, and specifically then in people with non-small cell lung cancer. They identified over 7,000 proteins that had cancer implications for therapy, for resistance, for prognosis, etc., and they categorized them based on the literature, TCGA data, etc., and used this machine learning process to figure out which proteins might be most specific for non-small cell lung cancer. And that's where they started. And so out of that 7,000 proteins, where they've identified which ones are angiogenic, which ones are involved with EMT or cell cycle or whatever it might be, they distilled it down to 388 proteins which they thought were worth testing in non-small cell lung cancer. And that's when I became involved.  They had a retrospective cohort of patients that had been treated with various immunotherapies. They looked at the analytic validation first, then applied it to this cohort. It looked good. Then they had a very large cohort, which they split, as you usually do with an assay, into a test set and then a validation set. For the test set, they wanted something more than a response. They wanted some indicator of long term benefit because that's where immunotherapy differentiates itself from chemotherapy and even targeted therapy. And so they picked PFS at 12 months. And I became involved at that point and it looked really good. I mean, if you look at the figures in the manuscript, the AUC is superb about their prediction and then what actually happened in the patient. And then in this paper, we applied it to a validation set of over 500 patients in a prospective trial, not randomized, it's called an observational trial. The investigator got to pick what they thought was the best therapy for that patient. And then in a blinded fashion, the proteomic assay experts did the analysis and applied it to the group.  And so what that means is some of the patients got chemotherapy alone, some got checkpoint immunotherapy monotherapy, some got in combination with chemotherapy. None of the patients in this study got a CTLA-4 inhibitor. That work is ongoing now. But what the study showed was that this assay can be used together with PD-L1 as what I would call a composite biomarker. You take the two together and it informs the oncologist about the meaning of that PD-L1. I'll give you an example. If that patient has a PD-L1 over 50% in their cancer and yet the PROphet test is negative, meaning less than 5 - it's a 0 to 10 scale - that patient for survival is better served by getting chemotherapy and immunotherapy. However, if the PROphet test is positive and the PD-L1 is over 50%, then the survival curves really look equivalent. As I said earlier, even in that group of patients, a lot of oncologists are reluctant to give them monotherapy. So if you have a test and the same sort of example is true for PD-L1 0, that you can differentiate. So this can really help inform the oncologist about what direction to go. And of course then you use your clinical judgment, you look at what you think of as the aggressiveness of the tumor or their liver metastases, etc. So again, that's how this test is being used for non-small cell lung cancer. And maybe I'll stop there and then I'll come back and add some other points. Dr. Rafeh Naqash: I definitely like your analogy of this therapy de-escalation strategy. Like you mentioned for PD-L1 high where the PROphet test is negative, then perhaps you could just go with immunotherapy alone. In fact, interestingly enough, I was invited to a talk at SITC a couple of weeks back and this exact figure that you're referring to was one of the figures in my slide deck. And it happened by chance that I realized that we were doing a podcast on the same paper today.  So I guess from a provocative question standpoint, when you look at the PD-L1 high cohort in the subset where you didn't see a survival difference for chemo plus immunotherapy versus immunotherapy alone, do you think any element of that could have been influenced by the degree of PD-L1 positivity above 50%? Meaning could there have been a cohort that is, let's say PD-L1 75 and above, and that kind of skews the data because I know you've published on this yourself also where the higher the PD-L1 above 50%, like 90% PD-L1 positivity survival curves are much better than 50% to 89%. So could that have somehow played a role? Dr. David Gandara: The first thing to say is that PD-L1 and the PROphet score, there's very little overlap. I know that sounds surprising, but it's also true for tumor mutational burden. There's very little overlap. They're measuring different things. The PD-L1 is measuring a specific regulatory protein that is applicable to some patients, but not all. That's why even in almost all of the studies, people with PD-L1 0 could still have some survival benefit. But in this case they're independent. And not in this paper, but in other work done by this group, the PROphet group, they've shown that the PROphet score does not seem to correlate with super high PD-L1. So it's not like the cemiplimab data where if you have a PD-L1 of greater than 90%, then of course the patient does spectacularly with monotherapy. The other thing that's important here is they had a group of around a little less than 100 patients that got chemotherapy alone. The PROphet score is agnostic to chemotherapy. And so that means that you're not just looking at some prognostic factor. It's actually clinical utility on a predictive basis. Dr. Rafeh Naqash: I think those are very important points. I was on a podcast a couple of days back. I think there's a theme these days we're trying to do for JCO Precision Oncology, we're trying to do a few biomarker based podcasts, and the most recent one that we did was using a tissue transcriptome with ctDNA MRD and you mentioned the composite of the PD-L1 and the PROphet test and they use a composite of the tissue transcriptome. I believe they called it the VIGex test as well as MRD ctDNA. And when your ctDNA was negative at, I believe, the three month mark, those individuals had the highest inflamed VIGex test or highest infiltration of T cells, STING pathway, etc. So are there any thoughts of trying to add or correlate tissue based biomarkers or ctDNA based correlations as a further validation in this research with the company? Dr. David Gandara: Right. So there are many things that are being looked at, various composites looking at the commutations that might affect the efficacy of immunotherapy and how they correlate with profit positivity or negativity. And I'll just give the examples of STK11 and KEAP1. As you know, there's some controversy about whether these are for immunotherapy, whether they're more prognostic or predictive. I'm one of the co-authors among many in the recently published Nature paper by Dr. Skoulidis and the group at MD Anderson which report that for KEAP1 positive especially, but also SDK11 mutated getting immunotherapy, that that's where the CTLA-4 inhibitors actually play the greatest role. So realizing that this is still controversial, there are preliminary data, not published yet, that'll be presented at an upcoming meeting, looking at many of these other aspects, P53, SCK11, KEAP1, other aspects, TMB, that's actually already published, I think in one of their papers. So yes, there's lots of opportunities.  The other cool thing is that this isn't a test, it's a platform. And so that means that the OncoHost scientists have already said, “What if we look at this test, the assay in a group of patients with small cell lung cancer?” And so I just presented this as a poster at the world conference in San Diego. And it turns out if you look at the biology of small cell, where neither PD-L1 nor TMB seem to be very important, if you look at the biology of small cell and you form an assay, it only shares 44 proteins out of the 388 with non-small cell. It's a different biology. And when we applied that to a group of patients with small cell lung cancer, again it had really pretty impressive results, although still a fairly small number of patients. So we have a big phase three study that we're doing with a pharmaceutical company developing immunotherapy where we are prospectively placing the PROphet test in a small cell trial.  The platform can also be altered for other cancer types. And at AACR, Dr. Jarushka Naidoo presented really impressive data that you can modify the proteins and you can predict immunotherapy side effects. So this is not like a company that says, “We have one test that's great for everything.” You know how some companies say, “Our test, you can use it for everything.” This company is saying we can alter the protein structures using AI machine learning assisted process to do it and we can have a very informed assay in different tumor types and different situations. So to me, it's really exciting. Dr. Rafeh Naqash: Definitely to me, I think, combining the AI machine learning aspect with the possibility of finding or trying to find a composite biomarker using less invasive approaches such as plasma or blood, definitely checks a lot of boxes. And as you mentioned, trying to get it to prospective trials as an integral biomarker perhaps would be likely the next step. And hopefully we see some interesting, exciting results where we can try to match or stratify patients into optimal combination therapies based on this test.  So now to the next aspect of this discussion, David, which I'm really excited about. You've been a leader and a mentor to many. You've led ISLC and several other corporate group organizations, et cetera. Can you tell us, for the sake of all the listeners, junior investigators, trainees, what being a mentor has meant for you? How your career has started many years back and how it's evolved? And what are some of the things that you want to tell people for a successful and a more exciting career as you've led over the years? Dr. David Gandara: Well, thank you for the question. Mentoring is a very important part of my own career. I didn't have an institutional mentor when I was a junior investigator, but I had a lot of senior collaborators, very famous people that kind of took me under their wing and guided me. And I thought when I basically establish myself, I want to give back by being a mentor to other people. And you wouldn't believe the number of people that I'm even mentoring today. And some of them are not medical oncologists, they're surgeons, they're radiation oncologists, they're basic scientists. Because you don't have to be an expert in that person's field to be a mentor. It helps, but in other words, you can guide somebody in what are the decision making processes in your career. When is it time to move from this institution onward because you can't grow in the institution you're in, either because it's too big or it's too small? So I established a leadership academy in the Southwest Oncology Group, SWOG. I've led many mentoring courses, for instance, for ISLC, now for International Society Liquid Biopsy, where I'm the executive committee liaison for what's called The Young Committee. So ISLB Society, totally devoted to liquid biopsy, six years old now, we have a Young Committee that has a budget. They develop projects, they publish articles on their own, they do podcasts. So what I'm saying is those are all things that I think opens up opportunities. They're not waiting behind senior people, they are leading themselves.  We just, at our International Lung Cancer Congress, reestablished a fellows program where a group of fellows are invited to that Huntington beach meeting. It's now in its 25th year and we spend a day and a half with them, mentoring them on career building. I'll just give you my first, I have the “Letterman Top 10”. So my first recommendation is if all you have is lemons, make lemonade. And what I'm meaning is find what you can do at your institution if you're a junior person, what you can claim to be your own and make the very best of it. But then as you get further along in my recommendations, one of them is learn when to say ‘no'. Because as a junior investigator the biggest threat to your career is saying ‘yes' to everybody and then you become overwhelmed and you can't concentrate. So I'll stop there. But anyway, yes, mentoring is a big part of my life. Dr. Rafeh Naqash: Well, thank you, David. This is definitely something that I'm going to try to apply to my career as well. And this has been an absolute pleasure, especially with all the insights that you provided, not just on the scientific side but also on the personal career side and the mentorship side. And hopefully we'll see more of this work that you and other investigators have led and collaborated on. perhaps more interesting plasma based biomarkers. And hopefully some of that work will find its home in JCO Precision Oncology. Thank you again for joining us today. Dr. David Gandara: My pleasure.

He's also the co-founder and chief medical officer at Massive Bio, an AI-driven platform that matches patients with clinical trials and novel therapies.  Our full disclosures are available in the transcript of this episode.   Arturo, it's great to have you on the podcast today.  Dr. Arturo Loaiza-Bonilla: Thanks so much, Shaalan. It's great to be here and talking to you today.  Dr. Shaalan Beg: So we're all familiar with the limitations and inefficiencies in patient recruitment for clinical trials, but there are exciting new technologies that are addressing these challenges. Your group developed a first-in-class, AI-enabled matching system that's designed to automate and expedite processes using real-world data and integrating next-generation sequencing results into the algorithm. You presented work at the ASCO Annual Meeting this year where you showed the benefits of AI and NGS in clinical trial matching and you reported about a twofold increase in potential patient eligibility for trials. Can you tell us more about this study?  Dr. Arturo Loaiza-Bonilla: Absolutely. And this is just part of the work that we have seen over the last several years, trying to overcome challenges that are coming because of all these, as you mentioned, inefficiencies and limitations, particularly in the manual patient trial matching. This is very time consuming, as all of us know; many of those in the audience as well experience it on a daily basis, and it's resource intensive. It takes specialized folks who are able to understand the nuances in oncology, and it takes, on average, even for the most experienced research coordinator or principal investigator oncologist, 25 minutes per trial. Not only on top of that, but in compound there's a lack of comprehensive genomic testing, NGS, and that complicates the process in terms of inability to know what patients are eligible for, and it can delay also the process even further.  So, to address those issues, we at Massive Bio are working with other institutions, and we're part of this … called the Precision Cancer Consortium, which is a combination of 7 of the top 20 top pharma companies in oncology, and we got them together. And let's say, okay, the only way to show something that is going to work at scale is people have to remove their silos and barriers and work as a collaborative approach. If we're going to be able to get folks tested more often and in more patients, assess for clinical trials, at least as an option, we need to understand further the data. And after a bunch of efforts that happened, and you're also seeing those efforts in CancerX and other things that we're working on together, but what we realize here is using an AI-enabled matching system to basically automate and expedite the process using what we call real-world data, which is basically data from patients that are actually currently being treated, and integrating any NGS results and comparing that to what we can potentially do manually. The idea was to do multi-trial matching, because if we do it for one study, yeah, it will be interesting, but it will not show the potential applicability in the real world.  So with all that background, the tool itself, just to give you the punchline of it, was proven highly effective in terms of efficiency. We were able to increase the number of potential matches, and not only that, but reducing the time to the matching. So basically, instead of spending 25 minutes, it could be done in a matter of seconds. And when you compound all that across multiple clinical trials, in this case, it was several sponsors coming together, we were able to reduce the manual effort of seeing patients and testing for clinical trials to basically 1 hour when it would have otherwise taken a ridiculous amount of time. And it was quantified as 19,500 hours of manual work, compared to 1 hour done by the system to uniquely match a cohort of about 5,600 patients that came into the platform. And this was across 23 trials. Now imagine if we can do it for the 14,000 clinical trials currently in clinicaltrials.gov.   So for us, this kind of was an eye-opening situation that if we can increase not only the efficiency but find even more trials by integrating comprehensive genomic testing, which in this case was a twofold increase in eligibility for clinical trials, that gives us not only the opportunity for optimized processes using AI but also a call to action that there is still a lot of under-genotyping. And I know American Cancer Society and ASCO and many others are working hard on getting that into fruition, but we need to have systems that remind us that certain patients are not tested yet and that can improve not only real patients, but the R&D and the process of innovation in the future. Dr. Shaalan Beg: Yeah, it's always an important reminder that even some of the highest impact IT solutions or AI solutions are most effective if they can be integrated into our normal clinical processes and into the normal workflow that we have in our clinics to help clinicians do their work quickly and more efficiently. Can you talk about how, over the last few years, the availability of NGS data in our electronic medical record (EMR) has evolved and whether that's evolving for the better? And what are some next steps in terms of making that data available at EMR so that such solutions can then pull that data out and do clinical trial matching?  Dr. Arturo Loaiza-Bonilla: Yes. So one of the things that we have seen over the last couple of years is because of the applicability of the 21st Century Cures Act, there is less “information blocking,” which is patients not being able to access their information in real time. Now, with the appearance of health exchanges, with patient-centric approaches, which is something that many innovators, including ours, are trying to apply, it's really becoming more relevant. So it's not only helping us to find the patients when they really need to get tested, but also is giving us the opportunity to put those patients into the right treatment pathway when found. Something that's still a challenge and I think we can work by being more collaborative once again – is my dream – is having these pre-screening hubs where no matter where you are in your cancer journey, you just go into that funnel and then are able to see, “Okay, you are in the second-line setting for non-small cell lung cancer, EGFR-mutated. Now, do you have a meta amplification, then you go for this study or this trial. Oh, you haven't been tested yet. You should get tested. You're a pancreas cancer patient who is KRAS wild type; well, there is a significant chance that you may have a biomarker because that's where most patients are enriched for.” So having that opportunity to at scale, just for the whole country, to get those patients access to that information, I think is crucial for the future of oncology. And I think you working at the NCI, more than most, know how the impact of that can help for those underrepresented patients to get more access to better treatment options and whatnot. And we can activate clinical trials as well in new models, decentralized models, adjusting time models, all those things can be leveraged by using biomarker testing in real time. Identification when the patient really needs a trial option or a medication option, because the data is telling us when to activate that in real time. Dr. Shaalan Beg: And identifying the patient for a potential clinical trial is one challenge. In oncology, given a lot of our trials, we are looking to enroll people at a specific time in their disease journey. So we call it first-line or second-line or third-line, becomes the next challenge. So just knowing someone has mutation number 1, 2, or 3 isn't enough to say they would be eligible for a second-line BRAF X, Y and Z mutation at a given trial. I've heard you talk a lot about this last-mile navigation for people once you've identified that they may be a soft match for a clinical trial. Can you talk about what you've seen in the ecosystem being developed on how AI is helping both clinics and patients navigate this last mile from the time they're identified for a clinical trial to the time they actually receive cycle 1, day 1? Dr. Arturo Loaiza-Bonilla: Yeah, absolutely. And that is such a critical point because, as you know, we have helped tons of patients getting trial options in thousands of cases. But even my own patients, I give them a report for trial options and they're like, “Okay, I still need help.” And we have been talking with ASCO, with the American Cancer Society, and many other very good teams, and what we see as an opportunity in technology here is leveraging those cancer journeys to know when the patient really has the opportunity to enroll in a trial, because this is a very dynamic environment. Not only the patient's condition changes because their cancer progresses, the hemoglobin changes, the cancer moves from one place to the other, and there's nuances in between, but also new medications are coming up, studies open and close, sites open and close.  So having this information as a hub, as what we call a command center, is the key to make this happen. And we can use the same tools that we use for Uber or for Instacart or whichever thing you want to do; it's already the same concept. When you need groceries, you don't need groceries every day. But Amazon gives you a ding that's like, “Well, I think you may be running out of milk,” because they already know how often you buy it, or just having the data behind the scenes of how typically these, in this case, patient journeys, may manifest based on the biomarker. So let's say a smoldering multiple myeloma is not the same across. One patient with biomarkers that make them very high risk, the risk of progressing to a multiple myeloma, first-line treatment-eligible patient is going to be much different than someone who has better risk cytogenetics. So using that tool to optimize the cancer journeys of those patients and being able to notify them in real time of new trial options, and also knowing when the patient really has that disease progression so there's a time of activation for trial matching again, the same way you get a credit score for buying a house, then you know exactly what options are in front of you at that very moment. And that is the last-mile component, which is going to be key. What we have seen that we feel is important to invest on, and we have invested heavily on it, is that until the patient doesn't sign the consent form for the clinical trial, that patient is completely unknown to most people. The site doesn't know them because they haven't been there, and they may be there, but they don't know about the options sometimes. But no one's going to invest in getting that patient to the finish line. There's a lot of support for patients on trials, but not before they enroll on trials. And we feel that this is a big opportunity to really exponentially grow the chances of patients enrolling in trials if we support them all the way from the very time they get diagnosed with cancer in any setting. And we can help that patient on a very unique journey to find the trial options using technology. So it's very feasible. We see it once again in many other equally complex tasks, so why not do it in oncology when we have all the bonafides across wanting to do this. Dr. Shaalan Beg: Can you give examples of where you are seeing it done outside of oncology that's a model that one can replicate? Dr. Arturo Loaiza-Bonilla: I mean, oncology is the toughest use case to crack. You have experiences with DCTs in the past and all that. So the big opportunities are for patients, for example, in psychiatry, when they need certain counseling and help. We see that also in medical devices, when people have diabetes and they really need a device specifically for that unique situation, or also for patients with cardiovascular risk that they can in real time get access to novel therapeutics. And that's how they have been able to enroll so quickly. And all these GLP-1 inhibitors, all those models are really almost completely decentralized nowadays in something that we can extrapolate for oncology once we have aligned the ecosystem to make it see them. This is something that we can really revolutionize care while we manage all the complex variables that typically come with oncology uses.  Dr. Shaalan Beg: I would imagine while you translate those learnings from outside of oncology into oncology, a lot of those processes will be human and AI combination activities. And as you learn more and more, the human component becomes a smaller fraction, and the technology and the AI becomes more of a component. Are you seeing a similar transition in the clinical trial matching space as well? Dr. Arturo Loaiza-Bonilla: Yes. So that's why people say humans are going to be replaced. They're not. Patients still want to see a human face that they recognize, they trust. Even family members of mine want to hear from me, even if they are in the top place in the world. What we can change with technology are those things that are typically just friction points. In this case, information gathering, collecting records, getting the data structured in a way that we can use it for matching effectively, knowing in real time when the patient progresses, so we can really give them the chances of knowing what's available in real time. And collecting the information from all these other stakeholders. Like, is the site open? Is the budget approved for that place? Is the insurance allowing the specific … do they have e-consent? Those things can be fully automated because they're just burdensome. They're not helping anyone. And we can really make it decentralized for e-consent, for just getting a screening. They don't need to be screened at the site for something that they're going to receive standard of care. We can really change that, and that's something that we're seeing in the space that is changing, and hopefully we can translate it fully in oncology once we are getting the word out. And I think this is a good opportunity to do so. Dr. Shaalan Beg: You talked about your dream scenario for clinical trial matching. When you think about your dream scenario as a practicing oncologist, what are the AI tools that you are most excited about making their way into the clinic, either wishful thinking or practically? Dr. Arturo Loaiza-Bonilla: I typically get feedback from all over the place on doing this, and I also have my own thoughts. But I always come to this for a reason. We all became physicians and oncologists because we like being physicians. We like to talk to patients. We want to spend the time. I tell folks in my clinic, I will see a thousand patients all the time as long as I don't have to do notes, as long as I don't have to place orders. But of course, they will have to hire 1,000 people ancillary to do all the stuff that we do.  If we can go back and spend all that time that we use on alert fatigue, on clicking, on gathering things, fighting insurance, and really helping align those incentives with clinical trials and biomarker testing and really making it a mankind or a humankind situation where we're all in this really together to solve the problem, which is cancer, that will be my dream come true. So I don't have to do anything that is clerical, that is not really helping me, but I want to use that AI to liberate me from that and also use the data that is generated for better insights. I think that I know my subject of expertise, but there's so many things happening all the time that it is hard to keep up, no matter how smart you are. If the tool can give me insights that I didn't even know, then leverage that as a CME or a board certification, that would be a dream come true. Of course, I'm just dreaming here, but it's feasible. Many of these ideas, as I mentioned, they're not new. The key thing is getting them done. The innovative part is getting stuff done, because I'm sure there's a gazillion people who have the same ideas as I did, but they just don't know whom to talk to or who is going to make it happen in reality. And that's my call to action to people: Let's work together and make this happen. Dr. Shaalan Beg: Well, Arturo, thanks a lot for sharing your insights with us today on the ASCO Daily News Podcast.

Dr. Shaalan Beg and Dr. Arjun Gupta discuss the rationale behind treatment breaks and assess the pros and cons based on feedback and data from patients with advanced-stage gastrointestinal cancers. TRANSCRIPT Dr. Shaalan Beg: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Shaalan Beg, an adjunct associate professor at UT Southwestern's Simmons Comprehensive Cancer Center in Dallas and senior advisor for clinical research at the National Cancer Institute. I'll be your guest host for the podcast today.  On today's episode, we'll be discussing treatment holidays in GI cancers. Treatment holidays, also known as drug holidays, are increasingly being discussed in clinical practice and involve voluntarily halting treatment for a duration determined by a health care provider if believed to be beneficial for a patient's well-being. We'll address the rationale behind treatment holidays and explore their potential risks and benefits. Joining me for this discussion is Dr. Arjun Gupta, a GI medical oncologist and health services researcher at the University of Minnesota. Dr. Gupta's research on treatment-related time toxicity has explored the benefits of taking a break from treatment.  Our full disclosures are available in the transcript of this episode.  Arjun, it's great to have you on the podcast today. Dr. Arjun Gupta: Thanks, Shaalan. It's a joy to be here. Dr. Shaalan Beg: Your research at the intersection of oncology, supportive care, and care delivery is extremely interesting and important in today's day and age. And you've done extensive work on the concept of time toxicity in cancer treatment. So as we think about these discussions in the clinic on treatment holidays and we talk about risks and benefits, I was hoping that you could help explain the concept of time toxicity in cancer treatment and what our listeners should remember from this. Dr. Arjun Gupta: Sure. So time toxicity is simply the time commitments that cancer care imposes on people with cancer and their loved ones, and the burden that comes along with these commitments. When we specifically think about time toxicity associated with a particular cancer treatment, such as chemotherapy, it's the time costs of pursuing, receiving, and recovering from cancer treatment. Now, we have to acknowledge that much of cancer care is essential. We need blood tests to monitor organ function, we need chemo to shrink tumors, and we need a caring oncologist to break bad news. But we have to remember that oncology care is delivered in an imperfect world. Appointments that should take 10 minutes can take 5 hours. People can have uncoordinated appointments, so they're coming to the clinic 3, 4, 5 times a week. And this affects, of course, not only the patient themselves but also their informal care partners and the entire network around them. And this cancer care can completely consume people's lives, leaving no time for rest, recovery, or pursuing joyful activities.  We interviewed patients and care partners in some qualitative work, and this was specifically people with advanced-stage gastrointestinal cancers. And we asked them what cancer care was like, and some of the words will shock you. People said things like, “It's like being on a leash.” “My life is like being on an extended COVID lockdown.” “Cancer is a full-time job.” A very experienced oncologist said, “It's like being on call. You may or not get called into the hospital, but you need to always be available.” And so this concept of time toxicity really applies to all people with cancer, but perhaps most so for people with advanced-stage, incurable cancer, when time is limited and when treatment regimens are perhaps not offering massive survival benefits. And in some cases, the time costs of pursuing the treatment can even overtake the very marginal survival benefit offered by the treatment. Dr. Shaalan Beg: This is particularly relevant for gastrointestinal cancers that, even in the world of advanced cancers, are highly burdensome in terms of their symptoms and the concept of being on call, whether you're a patient or a caregiver, and the burden that it has, I think will resonate with a lot of us, that it's always in the back of our mind on what if X, Y or Z were to happen? In the FOCUS4-N trial, a randomized trial from the UK, investigators assessed whether taking a treatment holiday for maintenance therapy for metastatic colorectal cancer would have a detrimental effect on progression free survival, overall survival, tolerability and toxicity. It looks like the study found that these decisions regarding maintenance therapy should be individualized, but there were not major differences in outcome. Can you comment on this and what applications that has for us in the clinic?  Dr. Arjun Gupta: Sure. But before diving into the FOCUS4-N clinical trial, I just wanted to share a story from the clinic yesterday. It happened in my clinic yesterday, but I'm sure it happens to thousands of patients across the world every single day. So it was the first visit for a patient with stage 4 colon cancer, and they had polymetastatic disease with disease in the lungs and the liver, no actionable biomarkers, and so very likely to be incurable. And so we discussed the usual port and palliative care appointments and chemotherapy backbone, and doing this every 2 weeks, and then doing scans after 4 to 6 doses of chemo to see how the cancer has responded. And then the patient looks up and asks that question, “Okay. So when does this end? When are we done? Do I need to do this forever and the rest of my life?” These are just such innocent and hopeful questions, because the truth is, there is no established end date. But I shared this story that right off the bat, people are looking for breaks. They've not even started chemo, they've not experienced physical or financial or time toxicity, but just psychologically, being on chemo long-term or forever is a very, very hard adjustment.  And so it's in this context that we should look at the FOCUS4-N clinical trial, which was a sub- study of a larger umbrella trial investigating whether continuing on maintenance chemo with oral capecitabine versus taking a treatment break from chemo affected the progression-free survival in people with metastatic colorectal cancer who had disease control after 4 to 6 months of upfront chemotherapy. So they randomized approximately 250 people. These people had largely been treated with FOLFOX or FOLFIRI. Most did not receive a biologic, and approximately half had partial response and half had stable disease. And then they did scans on these patients every two months or so. And the primary endpoint was progression free survival. The median PFS was approximately 4 months in the capecitabine arm and 2 months in the no treatment arm. Of course, as expected, side effects were higher in the capecitabine arm. But impressively, the overall survival was not different between these two arms. So what we're seeing here is that after this period of 4 to 6 months of intensive chemo, if we take a chemo break versus we get some oral chemotherapy, it may affect how quickly the cancer grows on scans, but it maybe does not affect how long patients live.  Now, how do these data apply for an individual patient? Now, these are incredibly nuanced and personal decisions and patients can and should choose what aligns best with their values. In some work done by Dr. Mike Brundage and colleagues in Canada, they asked 100 people with advanced cancer to consider hypothetical scenarios where a new treatment did not increase the overall survival, but potentially increased the progression free survival at the cost of some physical and other toxicities. And then they asked patients if and what PFS thresholds they would accept for this treatment. And around half of patients said no matter how big the PFS is, we do not want to accept the treatment because it causes some toxicity if I'm not going to live longer. Around a quarter of patients said that if the drug elongated progression free survival by three to six months, I would take it, because that's valuable to me even if I don't live longer. But surprisingly, 1 in 6 patients said that they would accept a treatment with no PFS benefit and no overall survival benefit, even at the cost of side effects. And there was a spectrum of reasons for these preferences that they maybe had the battle narrative that “I want to be a fighter, and I don't want to have any regrets,” just showing how complex people's attitudes and values can be. So the point is that continuing on maintenance treatment versus not doing it is not wrong. The point is we often don't even have these data to offer treatment breaks to patients so that they can make decisions that align with their goals.  So I think that's the biggest takeaway from the FOCUS4-N trial for me is that we have some hard data now to guide patients [FOCUS4-N Editorial]. Now, strictly speaking, when I'm talking to a patient about these data, doing oral capecitabine in 3-week cycles may not feel like much. It's perhaps a visit every 3 weeks for blood work and for meeting someone from the oncology team. There are no IV drugs given. If one does well, this might literally be one visit every 3 weeks. But we have to consider that things rarely go as smoothly as we plan them to. For someone living 100 miles away and having diarrhea and needing IV fluids, they may require 3 to 4 clinic visits for labs and monitoring.  In the FOCUS4-N trial, 50% of patients on capecitabine had at least one treatment delay, denoting some toxicity. In a different but similar CAIRO3 clinical trial that tested capecitabine and bevacizumab, 10% of patients had to discontinue treatment due to toxicity. And so it's important to remember that what might seem a simple and low burden to us may be very burdensome to patients. In some work that we've done ourselves [published in The Oncologist], even a single simple appointment to a clinic, such as a lab test, often ends up taking patients hours and hours. So I think it's all of this that we have to consider when we present these data to patients.  Dr. Shaalan Beg: You've talked about the FOCUS4-N trial, you mentioned the CAIRO3 study as well. How do you see this playing in the clinic? Somebody may be looking to attend a child's wedding or a notable birthday or a trip with the family, and you have the data from these trials supporting you. What are the patient factors in terms of their disease factors, patient factors that you think of when you recommend such a treatment break to a patient? Or, let me flip that over. Who would be a patient that you would be uncomfortable offering a treatment break for with metastatic colorectal cancer?  Dr. Arjun Gupta: Yes, I think disease characteristics are a crucial consideration when we consider who we're even offering these treatment breaks to. I think, number one, is the overall disease burden, and if there's any critical visceral disease and how that's responded and how much it's responded to the upfront chemotherapy induction. I think patients where we're worried about having several sites of bulky disease, some that have not responded as well, I think we have to be very, very careful considering complete chemotherapy breaks. In the FOCUS4-N trial, in subgroup analysis, patients who had stable disease tended to not benefit as much from the chemotherapy break, perhaps indicating that it's really people whose disease is responding, who are doing well, who don't have as much disease burden, who may be better served by these treatment breaks. Dr. Shaalan Beg: Fantastic. I think that provides very good direction for our listeners on how they can apply the results of these trials in their clinic.  So we've talked about treatment breaks as a way to give people their time back and to reduce time toxicity. What are other treatment strategies that you have seen deployed to reduce the burden of receiving cancer treatments in general? Dr. Arjun Gupta: You specifically asked about treatment strategies, so I'll start with that before moving to more broad interventions. We actually interviewed patients and care partners to ask them this question, and one of the things that they said was having prospective information from their oncology care team just about what my expected burden was going to be. So I think people recognize that they need oncology care and the clinicians are trying to help them and it's a broken system, but just knowing that 1 in 4 days will be spent with health care contact or not, or you will spend two hours arguing on the phone with a payer, for example, preparing and supporting people for these burdens is very important. There are obviously some alternative treatment schedules. Certain chemotherapies can be given less frequently now. So if you look at cetuximab in GI cancers, for example, when the initial trials were done, it was given every week, but now we more and more use it every two weeks. And it might not seem like much, but it can open up an entire week for a patient when they can think that I don't need to go in this week at all. So these are just some minor adjustments that we can make in the clinic.  But patients often highlight things that may perhaps not be in the direct control of the oncologist, but in the direct control of us as an oncology community. And perhaps the most frequently cited suggestion was having more care coordination and navigation services. So patients really requested more flexibility in the site of care: “Can I come closer to home?'' In the timing of their care, ‘'Can I come in at 2:00 PM after I get childcare instead of coming in at 9:00 AM?” They really requested cluster scheduling or having appointments on the same day, if possible, instead of taking up Monday, Tuesday, Wednesday, Thursday, coming in so many times. And all of this could potentially be achieved by having a designated care coordinator, someone working directly with the patient and their care partner. And then some patients also highlighted the benefits of telemedicine and home-based care, where they were able to be home more.  But we have to also recognize that those things are not universally good and often can increase burdens on the patients and care partners. Also, I wanted to highlight some feedback we received from oncology clinicians. We asked a variety of oncology clinicians, including nurses, APPs, physicians, schedulers, and social workers, what they thought were the causes of patients' time burden. You'll be surprised to hear that when they started talking about patients' time burdens, they slowly started to talk about their own time burdens. And they said, ‘‘We really want to help people, but we're just doing prior authorization and spending hours on the electronic medical record. And please fix my own time toxicity, and I will fix the patients' time toxicity,” which I thought was very profound because I think everybody who goes into medicine goes into it for the right reasons, and we end up not providing perfect care, not because of us, but because of the system. I take this as a very, very positive sign and as a hope for change. Dr. Shaalan Beg: What inspired you to focus on this topic and your research?  Dr. Arjun Gupta: So I personally just hate waiting at the doctor's office. But yes, it's also been wise mentors, including you, Shaalan, during residency and fellowship, who always told me to keep my ear to the ground and listen to patients. And in full disclosure, time toxicity, and what we've done with it recently, it's nothing new. It's been around for decades. And I think our research group has just sort of named it and shamed it, and now more and more people are starting to think about it.   But I can point to two specific instances that I think of. One was when I was starting fellowship in 2018, I read a piece by Dr. Karen Daily in the Journal of Clinical Oncology, where she quoted Henry Thoreau and said, “The price of anything is the amount of life, or time, that you exchange for it.” And it really struck a chord with me, entering the oncology discipline and seeing what people with cancer go through.   And then the second instance is, I remember my granddad, who was perhaps the most formative person in my life. We were very, very close. And when I was about to enter medical school, he was undergoing chemotherapy for lymphoma. The image that's imprinted in my head is of him putting ketchup on gulab jamun. And I can see Shaalan salivating. But for the listeners who may not know, gulab jamun is an Indian sweet made out of milk, flour, sugar, ghee, molded into balls, deep fried and then served in sugar syrup. And my granddad could not taste anything. He could not taste gulab jamun. All he could taste was ketchup. And so he would put ketchup on everything. And at his oncologist visits when I would accompany him, they would discuss the good news about the cancer shrinking and there being a response, and he was happy, but he could just not taste his gulab jamuns. And it made me realize very early on that the tumor is not the only target.  Dr. Shaalan Beg: What a wonderful story. I think those are really hard to measure, quantify, and when patients do bring those stories into the clinic, I think you realize that you have a very special connection with those patients as well, and it does help us as clinicians give personalized advice. So thanks for sharing.  Arjun, thanks for sharing your valuable insights with us on the ASCO Daily News Podcast today.

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.

Drs. Vamsi Velcheti and Nathan Pennell discuss novel approaches and key studies in lung cancer that were showcased at the 2024 ASCO Annual Meeting, including the Plenary abstracts LAURA and ADRIATIC.   TRANSCRIPT Dr. Vamsi Velcheti: Hello, I am Dr. Vamsi Velcheti, your guest host for the ASCO Daily News Podcast today. I'm a professor of medicine and director of thoracic medical oncology at the Perlmutter Cancer Center at NYU Langone Health. Today, I'm joined by Dr. Nate Pennell, the co-director of the Cleveland Clinic Lung Cancer Program and the vice chair of clinical research at the Taussig Cancer Center in Cleveland Clinic. Dr. Pennell is also the editor-in-chief of the ASCO Educational Book. Today, we will be discussing practice-changing abstracts and the exciting advances in lung cancer that were featured at the ASCO 2024 Annual Meeting. You'll find our full disclosures in the transcript of the episode. Nate, we're delighted to have you back on the podcast today. Thanks for being here. It was an exciting Annual Meeting with a lot of important updates in lung cancer. Dr. Nate Pennell: Thanks, Vamsi. I'm glad to be back. And yes, it was a huge year for lung. So I'm glad that we got a chance to discuss all of these late-breaking abstracts that we didn't get to talk about during the prelim podcast. Dr. Vamsi Velcheti: Let's dive in. Nate, it was wonderful to see all the exciting data, and one of the abstracts in the Plenary Session caught my attention, LBA3. In this study, the investigators did a comparative large-scale effectiveness trial of early palliative care delivered via telehealth versus in-person among patients with advanced non-small cell lung cancer. And the study is very promising. Could you tell us a little bit more about the study and your take-home messages? Dr. Nate Pennell: Yes, I think this was a very important study. So just to put things in perspective, it's now been more than a decade since Dr. Jennifer Temel and her group at Massachusetts General Hospital did a randomized study that showed that early interventions with palliative medicine consultation in patients with advanced non-small cell lung cancer significantly improves quality of life and in her initial study, perhaps even overall survival. And since then, there have been numerous studies that have basically reproduced this effect, showing that getting palliative medicine involved in people with advanced cancer, multiple different cancer types, really, has benefits.  The difficulty in applying this has been that palliative care-trained specialists are few and far between, and many people simply don't have easy access to palliative medicine-trained physicians and providers. So with that in mind, Dr. Temel and her group designed a randomized study called the REACH PC trial, where 1,250 patients were randomized with advanced non-small cell lung cancer to either in-person palliative medicine visits which is sort of the standard, or one in-person assessment followed by monthly telemedicine video visits with palliative medicine. Primary endpoint was essentially to show that it was equivalent in terms of quality of life and patient satisfaction. And what was exciting about this was that it absolutely was. I mean, pretty much across the board in all the metrics that were measured, the quality-of-life, the patient satisfaction, the anxiety and depression scores, all were equivalent between doing telemedicine visits and in-person visits. And this hopefully will now extend the ability to get this kind of benefit to a much larger group of people who don't have to geographically be located near a palliative medicine program. Dr. Vamsi Velcheti: Yeah, I think it's a great abstract, Nate and I actually was very impressed by the ASCO committee for selecting this for the Plenary. We typically don't see supportive care studies highlighted in such a way at ASCO. This really highlights the need for true interdisciplinary care for our patients. And as you said, this study will clearly address that unmet need in terms of providing access to palliative care for a lot of patients who otherwise wouldn't have access. I'm really glad to see those results. Dr. Nate Pennell: It was. And that really went along with Dr. Schuchter's theme this year of bringing care to patients incorporating supportive care. So I agree with you.  Now, moving to some of the other exciting abstracts in the Plenary Session. So we were talking about how this was a big year for lung cancer. There were actually 3 lung cancer studies in the Plenary Session at the Annual Meeting. And let's move on to the second one, LBA4, the LAURA study. This was the first phase 3 study to assess osimertinib, an EGFR tyrosine kinase inhibitor, in patients with EGFR mutant, unresectable stage III non-small cell lung cancer. What are your takeaways from this study?  Dr. Vamsi Velcheti: This is certainly an exciting study, and all of us in the lung community have been kind of eagerly awaiting the results of the study. As you know, for stage III non-small cell lung cancer patients who are unresectable, the standard of care has been really established by the PACIFIC study with the consolidation durvalumab after definitive concurrent chemoradiation. The problem with that study is it doesn't really answer the question of the role of immunotherapy in patients who are never-smokers, and especially in patients who are EGFR positive tumors, where the role of immunotherapy in a metastatic setting has always been questioned. And in fact, there have been several studies as you know, in patients with EGFR mutation positive metastatic lung cancer where immunotherapy has not been that effective. In fact, in the subgroup analysis in the PACIFIC study, patients with EGFR mutation did not really benefit from adding immunotherapy.  So this is an interesting study where they looked at patients with locally advanced, unresectable stage III patients and they randomized the patients 2:1 to osimertinib versus placebo following concurrent or sequential tumor radiation. The primary endpoint for the study was progression free survival, and a total of 216 patients were enrolled and 143 patients received a study treatment, which is osimertinib, and 73 received placebo. And 80% of the patients on the placebo arm crossed over to getting treatment at the time of progression.  So most of us in the lung cancer community were kind of suspecting this would be a positive trial for PFS. But however, I think the magnitude of the difference was truly remarkable. The median PFS in the osimertinib arm was 39.1 months and placebo was 5.6 months and the hazard ratio of 0.16. So it was a pretty striking difference in terms of DFS benefit with the osimertinib consolidation following chemoradiation. So it was truly a positive study for the primary endpoint and the benefit was seen across all the subgroups and the safety was no unexpected safety signals other than a slight increase in the radiation pneumonitis rates in patients receiving osimertinib and other GI and skin tox were kind of as expected. In my opinion, it's truly practice changing and I think patients with EGFR mutation should not be getting immunotherapy consolidation post chemoradiation. Dr. Nate Pennell: I completely agree with you. I think that this really just continues the understanding of the use of osimertinib in EGFR-mutant lung cancer in earlier stages of disease. We know from the ADAURA trial, presented twice in the Plenary at the ASCO Annual Meeting, that for IB, stage II and resectable IIIA, that you prolong progression free or disease free survival. So this is a very similar, comparable situation, but at an even higher risk population or the unresectable stage III patients. I think that the most discussion about this was the fact that the osimertinib is indefinite and that it is distinct from the adjuvant setting where it's being given for three years and then stopped. But I think all of us had some pause when we saw that after three years, especially in the stage III patients from ADAURA, that there were clearly an increase in recurrences after stopping the drug, suggesting that there are patients who are not cured with a time limited treatment, or at least with 3 years of treatment.  The other thing that is sobering from the study, and was pointed out by the discussant, Dr. Lecia Sequist, is if you look at the two-year disease-free survival in the placebo arm, it was only 13%, meaning almost no one was really cured with chemo radiation alone. And that really suggests that this is not that different from a very early stage IV population where indefinite treatment really is the standard of care. I wonder whether you think that's a reasonable approach. Dr. Vamsi Velcheti: I completely agree with you, Nate, and I don't think we cure a majority of our patients with stage III, and less so in patients who have EGFR-mutant, stage III locally advanced. As you just pointed out, I think very few patients actually make it that far along. And I think there's a very high rate of CNS micrometastatic disease or just systemic micrometastatic disease in this population that an effective systemic therapy of osimertinib can potentially have long term outcomes. But again, we perhaps don't cure a vast majority of them. I think that the next wave of studies should incorporate ctDNA and MRD-based assays to potentially identify those patients who could potentially go off osimertinib at some point. But, again, outside of a trial, I would not be doing that. But I think it's definitely an important question to ask to identify de-escalation strategies with osimertinib. And even immunotherapy for that matter, I think we all know that not all patients really require years and years of immunotherapy. They're still trying to figure out how to use immunotherapy in these post-surgical settings, using the MRD to de-escalate adjuvant therapies. So I think we have to have some sort of strategy here. But outside of a clinical trial, I will not be using those assays here to cite treatments, but certainly an important question to ask.  Moving on to the other exciting late-breaking abstracts, LBA5, the ADRIATIC study. This is another study which was also in the plenary session. This study was designed to address this question of consolidation immunotherapy, post chemo radiation for limited-stage small cell cancer, the treatment arms being durvalumab tremelimumab, and durvalumab observation. So what do you think about the study? This study also received a lot of applause and a lot of attention at the ASCO meeting. Dr. Nate Pennell: It was. It was remarkable to be there and actually watch this study as well as the LAURA study live, because when the disease free survival curves and in the ADRIATIC study, the overall survival curves were shown, the speakers were both interrupted by standing ovation of applause just because there was a recognition that the treatment was changing kind of before our eyes. I thought that was really neat. So in this case, I think this is truly a historic study, not necessarily because it's going to necessarily be an earth shakingly positive study. I mean, it was clearly a positive study, but more simply because of the disease in which it was done, and that is limited-stage small cell lung cancer. We really have not had a change in the way we've treated limited-stage small cell lung cancer, probably 25 years. Maybe the last significant advances in that were the advent of concurrent chemotherapy and radiation and then the use of PCI with a very modest improvement in survival. Both of those, I would say, are still relatively modest advances.  In this case, the addition of immunotherapy, which we know helps patients with small cell lung cancer - it's of course the standard of care in combination chemotherapy for extensive stage small cell lung cancer - in this case, patients who completed concurrent chemo radiation were then randomized to either placebo or durvalumab, as well as the third arm of durvalumab tremelimumab, which is not yet been recorded, and co primary endpoints were overall survival and progression free survival. And extraordinarily, there was an improvement in overall survival seen at the first analysis, with a median overall survival of 55.9 months compared to 33.4 months, hazard ratio of 0.73. So highly clinically and statistically significant, that translates at three years to a difference in overall survival of 56.5%, compared to 47.6%, or almost 10% improvement in survival at three years.  There was also a nearly identical improvement in progression-free survival, also with a hazard ratio of 0.76, suggesting that there's a modest number of patients who benefit. But it seems to be a clear improvement with the curves plateauing out. In my opinion, this is very comparable to what we saw with the PACIFIC study in stage III, unresectable non-small cell lung cancer, which immediately changed practice back when that first was reported. And I expect that this will change practice pretty much immediately for small cell as well. Dr. Vamsi Velcheti: Yeah, I completely agree, Nate. I think it's an exciting advance in patients with limited-stage small cell lung cancer. For sure, it's practice-changing, and I think the results were exciting.  So one thing that really intrigued me was in the extensive-stage setting, the benefit was very mediocre with one-to-two month overall survival benefit in both the PACIFIC and in IMpower trial. Here we are seeing almost two-year of median OS benefit. I was kind of puzzled by that, and I thought it may have to do with patients receiving radiation. And we've seen that with the PACIFIC, and makes you wonder if both the CASPIAN and the IMpower studies actually did not allow consolidation thoracic radiation. Hypothetically, if they had allowed consolidation thoracic radiation, perhaps we would have seen better outcomes. Any thoughts on that? Dr. Nate Pennell: We've been trying to prove that radiation and immunotherapy somehow go together better for a long time. Going back to the first description of the abscopal effect, and I'm not sure if I necessarily believe that to be the case, but in this setting where we truly are trying to cure people rather than merely prolong their survival, maybe this is the situation where it truly is more beneficial. I think what we're seeing is something very similar to what we're seen in PACIFIC, where in the stage IV setting, some people have long term survival with immunotherapy, but it's relatively modest. But perhaps in the curative setting, you're seeing more of an impact. Certainly, looking at these curves, we'll have to see with another couple of years to follow up. But a three-year survival of 56% is pretty extraordinary, and I look forward to seeing if this really maintains over the next couple of years follow up.  Moving beyond the Plenary, there were actually lots of really exciting presentations, even outside the Plenary section. One that I think probably got at least as much attention as the ones that we've already discussed today was actually an update of an old trial that's been presented for several prior years. And I'm curious to get your take on why you thought this was such a remarkable study. And we're talking about the LBA8503, which was the 5-year update from the CROWN study, which looked at previously untreated ALK-positive advanced non-small cell in cancer patients randomly assigned to lorlatinib, the third generation ALK inhibitor, versus crizotinib, the first generation ALK inhibitor. What was so exciting about this study, and why were people talking about it?  Dr. Vamsi Velcheti: Yeah, I agree, Nate. We've seen the data in the past, right? Like on the CROWN data, just first like a quick recap. This is the CROWN study, like the phase 3 study of third generation ALK inhibitor lorlatinib. So global randomized phase 3 study in patients with metastatic disease randomized to lorlatinib versus crizotinib, which is a controller. So the primary endpoint was PFS, and we've seen the results in the past of the CROWN readout quoted, with a positive study and the lorlatinib received FDA approval in the frontline setting. But the current study that was presented at the ASCO annual meeting is a kind of a postdoc analysis of five years. The endpoint for the study with central review stopped at three years, and this is actually a follow up beyond that last readout. Interestingly, in this study, when they looked at the median PFS at five years, the lorlatinib arm did not reach a median PFS even at five years and the hazard ratio is 0.19, which is kind of phenomenal in some ways. At 5 years, the majority of the patients were still on the drug. So that's quite incredible. And the benefit was more profound in patients with brain mets with a hazard ratio of 0.08. And again, speaking to the importance of brain penetrant, small molecule inhibitors, and target therapy, the safety profile, there were no additional safety signals noted in the study. We kind of know about the side effects of lorlatinib already from previous studies readouts. No unusual long-term toxicities.  I should note though, about 40% of patients did have CNS, AEs grade 1, 2 CNS toxicities on the  lorlatinib arm. And the other interesting thing that was also reported in the trial was dose reduction of lorlatinib did not have an impact on the PFS, which is interesting in my opinion. They also did some subgroup analysis, biomarker testing, biomarker populations. Patients who had P53 cooperation did much better with lorlatinib versus crizotinib. So overall, the other thing that they also had shown on the trial was the resistance mechanisms that were seen with lorlatinib were very different than what we are used to seeing with the earlier generation ALK inhibitors. The majority of the patients who develop resistance have bypass mechanisms and alterations in MAP kinase pathway PI3K/MTOR/PTEN pathway, suggesting that lorlatinib is a very potent ALK inhibitor and on target ALK mutations don't happen as frequently as we see with the earlier generation ALK inhibitors.  So I think this really begs the question, should we offer lorlatinib to all our patients with metastatic ALK-positive tumors? I think looking at the long-term data, it's quite tempting to say ‘yes', but I think at the same time we have to take into consideration patient safety tolerability. And again, the competitor arm here is crizotinib. So lorlatinib suddenly seems to be, again, cross trial comparisons, but I think the long-term outcomes here are really phenomenal. But at the same time, I think we've got to kind of think about patient because these patients are on these drugs for years, they have to live with all the toxicities. And I think the patient preferences and safety profile matters in terms of what drug we recommend to patients. Dr. Nate Pennell: I completely agree with you. I think the right answer, is that this has to be an individual discussion with patients. The results are incredibly exciting. I mean, the two-year progression free survival was 70%, and the five-year, three years later is still 60%. Only 10% of people are failing over the subsequent three years. And the line is pretty flat. And as you said, even with brain metastases, the median survival is in reach. It's really extraordinary. Moreover, while we do talk about the significant toxicities of lorlatinib, I thought it was really interesting that only 5% of people were supposedly discontinued the drug because of treatment related AEs, which meant that with dose reduction and management, it seems as though most patients were able to continue on the drug, even though they, as you mentioned, were taking it for several years.  That being said, all of us who've had experience with the second-generation drugs like alectinib and brigatinib, compared to the third-generation drug lorlatinib, can speak to the challenges of some of the unique toxicities that go along with it. I don't think this is going to be a drug for everyone, but I do think it is now worth bringing it up and discussing it with the patients most of the time now. And I do think that there will be many people for whom this is going to be a good choice, which is exciting. Dr. Vamsi Velcheti: Absolutely, completely agree. And I think there are newer ALK inhibitors in clinical development which have cleaner and better safety profiles. So we'll have to kind of wait and see how those pan out.  Moving on to the other exciting abstract, LBA8509, the KRYSTAL-12 study. LBA8509 is a phase 3 study looking at adagrasib versus docetaxel in patients with previously treated advanced metastatic non-small cell cancer with KRASG12C mutation. Nate, there's been a lot of hype around this trial. You've seen the data. Do you think it's practice-changing? How does it differentiate with the other drug that's already FDA approved, sotorasib?  Dr. Nate Pennell: Yeah, this is an interesting one. I think we've all been very excited in recent years about the identification of KRASG12C mutations as targetable mutations. We know that this represents about half of KRAS mutations in patients with non-small cell lung cancer, adenocarcinoma, and there are two FDA-approved drugs. Sotorasib was the first and adagrasib shortly thereafter. We already had seen the CodeBreaK 200 study, which was a phase 3 study of sotorasib versus docetaxel that did modestly prolong progression free survival compared to docetaxel, although did not seem to necessarily translate to an improvement in overall survival. And so now, coming on the heels of that study, the KRYSTAL-12 study compared adagrasib, also the KRASG12C  inhibitor versus docetaxel and those with previously treated non-small cell with KRASG12C. And it did significantly improve progression free survival with a hazard ratio of 0.58. Although when you look at the median numbers, the median PFS was only 5.5 months with the adagrasib arm compared to 3.8 months with docetaxel. So while it is a significant and potentially clinically significant difference, it is still, I would say a modest improvement.   And there were some pretty broad improvements across all the different subgroups, including those with brain metastases. It did improve response rate significantly. So 32% response rate without adagrasib, compared to only 9% with docetaxel. It's about what you would expect with chemotherapy. And very importantly, in this patient population, there was activity in the brain with an intracranial overall response rate among those who had measurable brain metastases of 40%. So certainly important and probably that would distinguish it from drugs like docetaxel, which we don't expect to have a lot of intracranial toxicity. There is certainly a pattern of side effects that go along with that adagrasib, so it does cause especially GI toxicity, like diarrhea, nausea, vomiting, transaminitis. All of these were actually, at least numerically, somewhat higher in the adagrasib arm than in docetaxel, a lot more hematologic toxicity with the docetaxel. But overall, the number of serious adverse events were actually pretty well matched between the two groups. So it wasn't really a home run in terms of favorable toxicity with that adagrasib.  So the question is: “In the absence of any data yet on overall survival, should this change practice?” And I'm not sure it's going to change practice, because I do think that based on the accelerated approval, most physicians are already offering the G12C inhibitors like sotorasib and adagrasib, probably more often than chemotherapy, I think based on perceived improvement in side effects and higher response rates, modestly longer progression-free survival, so I think most people think that represents a modest improvement over chemotherapy. And so I think that will continue. It will be very interesting, however, when the overall survival report is out, if it is not significantly better, what the FDA is going to do when they look at these drugs.  Dr. Vamsi Velcheti: Thanks so much. Very well summarized. And I do agree they look more similar than dissimilar. I think CodeBreaK-200 and the KRYSTAL-12, they kind of are very identical. I should say, though I was a little surprised with the toxicity profile of adagrasib. It seemed, I mean, not significantly, but definitely seemed worse than the earlier readouts that we've seen. The GI tox especially seems much worse on this trial. I'm kind of curious why, but if I recall correctly, I think 5% of the patients had grade 3 diarrhea. A significant proportion of patients had grade 3 nausea and vomiting. And the other complicating thing here is you can't use a lot of the antiemetics because of the QT issues. So that's another problem. But I think it's more comparable to sotorasib, in my opinion.  Dr. Nate Pennell: While this is exciting, I like to think of this as the early days of EGFR, when we were using gefitinib and erlotinib. They were certainly advances, but we now have drugs that are much more effective and long lasting in these patients. And I think that the first-generation inhibitors like sotorasib and adagrasib, while they certainly benefit patients, now is just the beginning. There's a lot of research going on, and we're not going to talk about some of the other abstracts presented, but some of the next generation G12C inhibitors, for example, olomorasib, which did have also in the same session, a presentation in combination with pembrolizumab that had a very impressive response rate with potentially fewer side effects, may end up replacing the first generation drugs when they get a little bit farther along. And then moving on to another one, which I think potentially could change practice. I am curious to hear your take on it, was the LBA8505, which was the PALOMA-3 study. This was interesting in that it compared two different versions of the same drug. So amivantamab, the bispecific, EGFR and MET, which is already approved for EGFR exon 20 non-small cell lung cancer, in this case, in more typical EGFR-mutated non-small cell lung cancer in combination with osimertinib with the intravenous amivantamab, compared to the subcutaneous formulation of amivantamab. Why would this be an important study? Dr. Vamsi Velcheti: I found this study really interesting as well, Nate. And as you know, amivantamab has been FDA approved for patients with exon 20 mutation. And also, we've had, like two positive readouts in patients with classical EGFR mutations. One, the MARIPOSA study in the frontline setting and the MARIPOSA-2, in the second-line post osimertinib setting. For those studies, the intravenous amivantamab was used as a treatment arm, and the intravenous amivantamab had a lot of baggage to go along with it, like the infusion reactions and VTEs and other classic EGFR related toxicity, skin toxicities. So the idea behind developing the subcutaneous formulation of amivantamab was mainly to reduce the burden of infusion, infusion time and most importantly, the infusion related reactions associated with IV formulation.  In a smaller phase 2 study, the PALOMA study, they had looked at various dosing schemas like, subcutaneous formulation, and they found that the infusion related reactions were very, very low with the subcutaneous formulation. So that led to the design of this current study that was presented, the PALOMA-3 study. This was for patients who had classical EGFR mutations like exon 19, L858R. The patients were randomized 1:1 to subcutaneous amivantamab with lazertinib versus IV amivantamab plus lazertinib. The endpoints for the study, it's a non-inferiority study with co primary endpoints of C trough and C2 AUC, Cycle 2 AUC. They were looking at those pharmacological endpoints to kind of demonstrate comparability to the IV formulation. So in this study, they looked at these pharmacokinetic endpoints and they were essentially identical. Both subcutaneous and IV formulations were compatible. And in terms of clinical efficacy as well, the response rate was identical, no significant differences. Duration of response was also identical. The PFS also was comparable to the IV formulation. In fact, numerically, the subcutaneous arm was a little better, though not significant. But it appears like, you know, the overall clinical and pharmacological profile of the subcutaneous amivantamab was comparable. And most interestingly, the AE profile, the skin toxicity was not much different. However, the infusion reactions were substantially lower, 13% with the subcutaneous amivantamab and 66% with IV amivantamab. And also, interestingly, the VTE rates were lower with the subcutaneous version of amivantamab. There was still a substantial proportion of patients, especially those who didn't have prophylactic anticoagulation. 17% of the patients with the subcutaneous amivantamab had VTE versus 26% with IV amivantamab. With prophylaxis, which is lower in both IV and subcutaneous, but still subcutaneous formulation at a lower 7% versus 12% with the IV amivantamab.  So overall, I think this is an interesting study, and also the authors had actually presented some interesting data on administration time. I've never seen this before. Patients reported convenience using a modified score of patient convenience, essentially like patients having to spend a lot of time in the infusion site and convenience of the patient getting the treatment. And it turns out, and no surprise, that subcutaneous amivantamab was found to be more convenient for patients.  So, Nate, I want to ask you your take on this. In a lot of our busy infusion centers, the time it takes for those patients to get the infusion does matter, right? And I think in our clinic where we are kind of fully booked for the infusion, I think having the patients come in and leave in 15, 20 minutes, I think it adds a lot of value to the cancer center operation.  Dr. Nate Pennell: Oh, I completely agree. I think the efficacy results were reassuring. I think the infusion related reaction difference, I think is a huge difference. I mean, I have given a fair amount of amivantamab, and I would say the published IRR rate of 66%, 67% I would say, is maybe even underestimates how many patients get some kind of reaction from that, although it really is a first dose phenomenon. And I think that taking that down to 13% is a tremendous advance. I think fusion share time is not trivial as we get busier and busier. I know our cancer center is also very full and it becomes challenging to schedule people, and being able to do a five-minute treatment versus a five-hour treatment makes a big difference for patients.  It's interesting, there was one slide that was presented from an efficacy standpoint. I'm curious about your take on this. They showed that the overall survival was actually better in the subcu amivantamab arm, hazard ratio of 0.62. Now, this was only an exploratory endpoint. They sort of talk about perhaps some rationale for why this might be the case. But at the very least, I think we can be reassured that it's not less effective to give it and does seem to be more tolerable and so I would expect that this hopefully will be fairly widely adopted. Dr. Vamsi Velcheti: Yeah, I agree. I think this is a welcome change. Like, I think the infusion reactions and the resources it takes to get patients through treatments. I think it's definitely a win-win for patients and also the providers.  And with that, we come to the conclusion of the podcast. Nate, thank you so much for the fantastic insights today.

Dr. Shaalan Beg highlights practice-changing studies in GI cancers featured at the 2024 ASCO Annual Meeting, including the ESOPEC trial in esophageal adenocarcinoma and durable responses to PD-1 blockade alone in mismatch repair-deficient locally advanced rectal cancer. TRANSCRIPT Geraldine Carroll: Welcome to the ASCO Daily News Podcast. I'm Geraldine Carroll, a reporter for the ASCO Daily News. My guest today is Dr. Shaalan Beg, an adjunct associate professor at UT Southwestern Simmons Comprehensive Cancer Center. Dr. Beg will be discussing practice- changing abstracts and other key advances in GI oncology that were presented at the 2024 ASCO Annual Meeting. His full disclosures are available in the transcript of this episode.  Dr. Beg, thanks for being on the podcast today.  Dr. Shaalan Beg: Thank you for having me. Geraldine Carroll: Let's begin with LBA1, the ESOPEC trial. This was featured in the Plenary Session, and this study compared two treatment strategies for locally advanced esophageal adenocarcinoma that could be treated with surgery. The strategies include the CROSS protocol, which consisted of chemoradiotherapy before surgery, and the FLOT protocol of chemotherapy before and after surgery. Can you tell us about this practice-changing study, Dr. Beg? Dr. Shaalan Beg: Yes. According to this study, perioperative chemotherapy with FLOT was better than neoadjuvant therapy with chemoradiation and carbo-taxol for people with adenocarcinoma of the esophagus. There were 438 patients enrolled on this phase 3 study. R0 resection rates were fairly similar across both groups. The PCR rates were a little higher on the FLOT group. But when you look at the median overall survival difference, 66 months in the FLOT group versus 37 months in the CROSS group, 3-year survival was 57% versus 50% favoring FLOT therapy as well.  So a couple of caveats on this clinical trial, because the first thing to note is that the standard treatment for this disease has evolved because we now don't only give CROSS chemoradiation, we also give immunotherapy after the completion of chemoradiation for this group of patients. And in this study, since it predated that standard of care, patients did not receive immunotherapy. But having said that, the take home for me here is that chemotherapy is better than chemoradiation for this group of patients, recognizing the fact that 1) they only enrolled adenocarcinoma patients, and 2) patients with high T stage were not included. So the folks with high T stage would be those who we would expect would benefit from the radiation aspect. So my take home here is that more chemotherapy is better in the perioperative space. Radiation should be considered for individuals who need more local control. But in general, I think we're going to see us moving more towards chemotherapy-based regimens with FLOT for this group of patients. Geraldine Carroll: Great. So moving on to rectal cancer, in LBA3512, investigators reported durable, complete responses to PD-1 blockade alone in mismatch repair deficient locally advanced rectal cancer. Can you tell us more about the promising durable responses that occurred in this trial?  Dr. Shaalan Beg: On first glance, seeing that immunotherapy has good activity in patients with mismatched repair deficient rectal cancer isn't really headline breaking news anymore. We've known about this activity for this group of patients for many years. Earlier at ASCO, the investigators presented early results of this compound for people receiving six months of dostarlimab therapy for people with mismatched repair deficient, locally advanced rectal cancer, and showed that they had a very high complete response rate. At that time, it generated a lot of interest and there was a lot of curiosity on whether these outcomes will be sustained. We don't know other characteristics of their biologic status and whether this was some sort of reflection of the patients who are selected or not.   So here in this presentation at ASCO 2024, they did come back to present follow-up data for people with mismatch repair deficient colorectal cancer, having received 6 months of dostarlimab. Forty-seven patients had been enrolled, and the 41 patients who had achieved a clinical complete response continued to have disease control with no distant metastases. So that's very compelling information. There were no additional serious adverse events greater than grade 2 that they saw, and they did follow circulating tumor DNA, and those did normalize even before they had their colonoscopy to examine their tumors.  So, again, we're continuing to see very encouraging data of immunotherapy, and the response rate with dostarlimab seems to be very interesting for this disease, and it will be interesting to see how this pans out in larger studies and how this translates into the use of dostarlimab across other diseases where other checkpoint inhibitors are currently being used. Geraldine Carroll: Absolutely. So, moving on to LBA3501. The COLLISION trial looked at surgery versus thermal ablation for small cell colorectal liver metastases. This was an international, multicenter, phase 3, randomized, controlled trial. How will this study change clinical practice?  Dr. Shaalan Beg: Kudos to the investigators here. They looked to understand the difference in outcome in treating people with colorectal cancer with liver only metastases. These clinical trials are extremely difficult to design. They're very difficult to enroll on because of the multidisciplinary aspect of the interventions and patient and provider biases as well. So on this clinical trial, the investigators enrolled people with resectable colorectal cancer, liver metastases so they did not have any metastases outside the liver. Patients were required to have 10 or less known metastases that were less than 3 cm in size. There were other allowances for larger tumors as well. And after an expert panel review, patients were randomized to either resection or ablation. It was up to the physicians whether they performed these laparoscopically or openly or percutaneously, depending on the biology of the patient and the anatomical presentation.  There was a predefined stopping rule at the half-time for this clinical trial, which showed a benefit in the experimental arm of ablation compared to standard of care. The overall survival was not compromised. Progression-free survival was not compromised with local therapy. But there were differences in morbidity and mortality, as we would expect, one being a surgical procedure and the other being ablation, where, according to this study, of the 140 or so patients who received either treatment, 2.1% of people who underwent resection died within 90 days of surgery. The AE rate was 56% in the resection sample compared to 19% in ablation, and the 90-day mortality for ablation was 0.7%. So less morbidity, improved mortality, reduced adverse events with ablation versus surgical resection without compromising local control and overall survival.   And I think for practice here in the United States, this does provide very interesting data for us to take back to the clinic for lesions that are relatively small and could generally be addressed by both surgery and ablation. Historically, there are various non biologic factors that could go into deciding whether someone should have surgery or ablation, and it could be based on who the physician is, who's seeing the patient, what the practice patterns in a specific organization are, and where their expertise lie. But here we're seeing that ablation for the small lesions is a very effective tool with very good local control rates, and again, in this selected group of patients with liver only metastases. And I think it is going to make tumor board discussions very interesting with data backing ablation for these lesions. Geraldine Carroll: Well, let's move onto the MOUNTAINER study. This study created some buzz in the colorectal cancer space. That's Abstract 3509. Can you tell us about the final results of this phase 2 study of tucatinib and trastuzumab in HER2-positive metastatic CRC? What are your thoughts on this treatment option, which seems to be well tolerated? Dr. Shaalan Beg: So, HER2 overexpression or amplification occurs in about 3 to 5% of patients with metastatic colorectal cancer and up to 10% of people who have a RAS/RAF wild type disease. On the previous episodes of the podcast we have covered precision targeted therapy in colorectal cancer, focusing on c-MET, focusing on BRAF, and here we have updated results targeting HER2 for colorectal cancer. And the results of the MOUNTAINEER study have been out for a while. This is a phase 2 study looking at combining tucatinib which is a highly selective HER2 directed TKI with trastuzumab, the monoclonal antibody for HER2 targeting. And what they found on this study is the confirmed overall response rate was 38%. Duration of response was 12 months, overall survival was 24 months and these are the results that have been already released and now we have an additional 16 months of follow up and these results continue to hold on. PFS and overall survival gains were held, which makes it a very interesting option for people with colorectal cancer. You mentioned the tolerability aspect and side effects. I think it's important to know the spectrum of side effects for this disease may be a little different than other TKIs. There's hypertension, but there's also the risk of diarrhea, back pain and pyrexia, with the most common grade 3 treatment related adverse event was an increase in AST level seen in 10% of people of grade 3 and above.  So where does that really leave us? There is a confirmatory randomized first-line trial of tucatinib and trastuzumab in the first line setting, which is currently ongoing. So we'll stay tuned to see where that leads us. And with the HER2 space right now for colorectal cancer with the development of antibody drug conjugates, we may have more than one option for this group of patients once those trials read out. Geraldine Carroll: Excellent. Well, moving on to LBA4008, that's the CheckMate-9DW trial. This trial reported first results looking at nivolumab plus ipilimumab versus sorafenib or lenvatinib as first-line treatment for advanced hepatocellular carcinoma. Can you tell us about this trial? Will there be a potential new standard of care in advanced HCC? Dr. Shaalan Beg: When we think about patients with advanced HCC, the only treatment option that they had for about a decade and a half were just oral track tyrosine kinase inhibitors that had modest to moderate clinical activity. Since then, we've seen that combination therapy is better than TKI therapy, and the combination therapy has taken two different forms. One is a combination of checkpoint inhibitor and antiangiogenic therapy, such as in the combination of atezolizumab and bevacizumab. The other is a combination of dual checkpoint inhibitor therapy. Here we are talking about the results of nivolumab and ipilimumab. Previously, we've talked about the combination of durva and tremi for the treatment of patients with HCC.   So in this study, nivo was given for the first 4 cycles, nivo and ipi were given together, nivo 1 mg per kg, and IPI 3 mgs per kg every 3 weeks for 4 cycles. And then the CTLA-4 inhibitor ipilimumab was stopped. And this was followed by monotherapy nivolumab every 4 weeks until disease progression or up to 2 years. And it was compared to dealers' choice, lenvatinib or sorafenib. The median overall survival of nivo-ipi was 23 months versus 20 months with lenvatinib-sorafenib. The 24-month overall survival was 49% with ipi-nivo versus 39%. And the overall response rate with nivo-ipi was 36% compared to 13%. So again, significantly improved clinical activity.   And when we talk about immunotherapy combinations, the question that comes to mind is how well is this tolerated? There's a lot of work and iteration that took place in figuring out what the right combination strategy of ipi and nivo should be, because some of the earlier studies did demonstrate fairly high adverse events in this group of patients. So on this study, we saw that grade 3 or 4 treatment related adverse events were seen in 41% of people who received nivo-ipi and 42% if they received lenvatinib or sorafenib. So, certainly a high proportion of treatment related adverse events, but probably also reflective of the disease population, which is being tested, because those numbers were fairly similar in the control arm as well.  So we've known that nivo-ipi is active in HCC. There is an approval in the second-line space, so it remains to be seen if this data helps propel nivo-ipi to the first-line space so we end up with another combination regimen for patients with advanced hepatocellular carcinoma.  Geraldine Carroll: Excellent. Well, before we wrap up the podcast, I'd like to ask you about LBA3511. In this study, investigators looked at total neoadjuvant treatment with long course radiotherapy versus concurrent chemoradiotherapy in local advanced rectal cancer with high risk factors. So this was a multicenter, randomized, open label, phase 3 trial. What are your key takeaways here? Dr. Shaalan Beg: Key takeaway here is that total neoadjuvant therapy was better than the conventional chemoradiation followed by chemo. So this clinical trial enrolled people with T4a/b resectable disease with clinical N2 stage, and they were randomized, as you mentioned, to receiving chemoradiation with radiation capecitabine followed by surgery, and then CAPOX or capecitabine versus chemo, short-course radiation, and additional chemotherapy followed by surgery.  And when we compare both arms, the total neoadjuvant therapy led to improved disease-free survival, improved PCR rates compared to standard concurrent neoadjuvant chemo radiotherapy in this group of patients. The two arms were fairly well-balanced. The number of T4 lesions was a little higher in the chemoradiation group. There were 49% in the chemo radiation group versus 46% had clinically T4 disease, but the nodal status was fairly similar. We should keep in mind that the other baseline characteristics were fairly well balanced.  And when we look at the outcomes, the disease-free survival probability at 36 months was 76% in the total neoadjuvant group compared to 67% with chemoradiation. And the metastasis free survival in total neoadjuvant therapy was 81% versus 73%. So a fairly compelling difference between the two arms, which did translate into an overall survival of 89% versus 88% in the two groups. So definitely higher disease-free survival and metastasis free survival, no difference on the overall survival with these groups. And it talks about the importance of intensifying chemotherapy upfront in this group of patients who can have a fairly high burden of disease and may struggle with receiving chemotherapy postoperatively. Geraldine Carroll: Excellent. Well, thank you, Dr. Beg, for sharing your fantastic insights with us on these key studies from the 2024 ASCO Annual Meeting. It's certainly a very exciting time in GI oncology. Dr. Shaalan Beg: Absolutely.

Dr. Shannon Westin and her guest, Dr. Bryan Schneider discuss the article “ECOG-ACRIN EAZ171: Prospective Validation Trial of Germline Predictors of Taxane-induced Peripheral Neuropathy in Black Women with Early Stage Breast Cancer” recently published in the JCO and presented at the 2024 ASCO Annual Meeting. TRANSCRIPT  The guest on this podcast episode has no disclosures to declare. Shannon Westin: Hello, everyone, and welcome to another episode of JCO After Hours, the podcast where we get in depth on manuscripts published in the Journal of Clinical Oncology. I am your host, Shannon Westin, GYN Oncology Extraordinaire and also the Social Media Editor of the Journal of Clinical Oncology. And it is my great pleasure to present some really incredible work today that is going to be a dual publication in the Journal Clinical Oncology and a presentation at the American Society of Clinical Oncology Annual Meeting on Monday, June 3. And this is the “ECOG-ACRIN EAZ171: Prospective Validation Trial of Germline Predictors of Taxane-induced Peripheral Neuropathy in Black Women with Early Stage Breast Cancer.” And I am joined today by the senior author on the presentation and the primary author on the manuscript, Dr. Bryan Schneider. He is the Vera Bradley Professor of Oncology, the Professor of Medicine and Medical Molecular Genetics at the Indiana University Melvin and Bren Simon Comprehensive Cancer Center in Indianapolis. Welcome, Dr. Schneider. Dr. Bryan Schneider: Dr. Westin, thank you for having me on today. Shannon Westin: We're so excited and we're really excited to really summarize this incredible work that's being presented today. So, first, let's just levelset. Can you speak a little bit about peripheral neuropathy and the most common causes in patients with cancer? Dr. Bryan Schneider: Yeah, I mean, I think for those of us who treat patients using the taxanes, we recognize probably one of the most important and common side effects that we deal with is peripheral neuropathy, and one that can, I think, impact both quality of life, but also impacts the ability to maintain dose intensity. When we think about risk factors for neuropathy, historically, I think obesity has been reported as a potential risk factor, as has diabetes and other conditions which put people at risk for neuropathy. Shannon Westin: And prior to your work that you'll discuss with us today, what do we know about the incidence of peripheral neuropathy in patients that identify as black? Dr. Bryan Schneider: Yeah. So, interestingly, I think we've recognized that patients who self identify as black have disparate outcomes in terms of inferior survival and more aggressive subtypes of breast cancer, like triple negative breast cancer. But I think the idea of toxicity being a disparate factor as well is probably a more recent one. Interestingly, as we set out to identify biomarkers to predict outcomes in the large adjuvant trial E5103, we weren't really setting out to look at this by race. We were using at that time, genome-wide approaches to identify biomarkers for toxicity and also efficacy. But what was interesting as we did that one of the most important predictors, as we looked across a number of important toxicities, was ancestry. And really the science spoke to us, it was very clear that patients of African ancestry had higher rates of bev-induced hypertension, anthracycline-induced cardiomyopathies and also peripheral neuropathy. Shannon Westin: That's so interesting. We have so much overlap in gynecologic oncology and breast cancer. And I don't know that I've ever seen work like this. And now it's making me very intrigued and making me want to move forward to that. Can you talk a little bit more about this ECOG-ACRIN E5103, like briefly about the study and what it demonstrated specifically? Dr. Bryan Schneider: Yeah. So E5103 was an adjuvant breast cancer trial that really set out to look at the impact of bevacizumab in the curative setting. This was a 5000 patient trial that randomized patients the standard backbone of chemotherapy. So everyone received four cycles of doxorubicin and cyclophosphamide, followed by weekly paclitaxel, and then with or without the addition of bevacizumab. So the parent clinical trial showed, as we know now, bevacizumab didn't add benefit, but certainly this was a fertile ground for us to use genomic markers to try to identify a number of other important factors and predictors. Shannon Westin: And what did you find genomically in that study that led to kind of where we are now? Dr. Bryan Schneider: Initially, what we found is that ancestry was a major predictor of neuropathy. And in that trial we saw essentially a doubling of the risk of grade 2 and above and a doubling of the risk of grade 3 and above neuropathy. When we then looked comprehensively across the genome for common variants that might put patients at risk for neuropathy, we had enough patients in the black population to identify some markers that seemed to differentially predict the risk of neuropathy in the patients of African ancestry. So there we found a variant in the gene FCAMR, which appeared to be protected from neuropathy, and FCAMR is known to have an immune modulatory effect. But importantly, we also found that rare variants, so we did this using an exome wide approach in a gene called SPF2, predicted an increased risk of neuropathy. Now, interestingly, that gene SPF2 is also thought to contribute to a hereditary form of neuropathy, Charcot-Marie-Tooth. Here, what we found, obviously, is that if you inherit two of these variants, you probably have a hereditary neuropathy, but if you inherit one, you may not have neuropathy at baseline, but if exposed to a neurotoxin, much more predisposed to that event. Shannon Westin: That is so intriguing and makes so much physiologic sense. So, can you talk a little bit about how that led to the development of the current study, the objectives design, that type of thing? Dr. Bryan Schneider: Yeah. I think, overarching question and concern is, and we see this with all clinical trials in the United States, is that we're seeing disparate outcomes in a population that are largely underrepresented in our clinical trials. And so one of the first things we wanted to do was really focus on the population that was being disparately affected. So EAZ171 was set out to accrue patients, and in fact, only accrue patients who were self described as a Bck race or African American. So the goal of this trial then was to see if, number one, we could further predict which patients were going to get neuropathy based on our germline genotyping, and then also to better personalize the type of taxane based, again on genomics, but also on the risk of dose reductions, risk of neuropathy, impact on financial toxicity, quality of life, and a number of other, what we felt to be, important clinical variables. Shannon Westin: So let's get into the details. What did you find regarding the incidence of neuropathy in the study, and how was it impacted by the type of chemotherapy the patient received? Dr. Bryan Schneider: Yeah. So the starting point, the primary objective of that study, was to try to validate a high and low risk composite score for neuropathy. And the trial was negative, meaning our genotypes did not predict significantly differences based on the germline genotyping. Now, interestingly, the genotyping did numerically separate, meaning those in the high risk category had about a 12% higher risk of neuropathy, but this did not meet statistical significance. Another major or key secondary endpoint, though, was to look at the type of taxane and its impact in this population. And indeed, what we found is that patients who received paclitaxel had a markedly and statistically significantly higher risk of both grade 2 and above and grade 3 and above peripheral neuropathy. And in addition, we saw more dose reductions, both because of TIPN and all causes in the paclitaxel arm. Shannon Westin: So why do you think you were unable to validate the genomic predictors in the current study? Dr. Bryan Schneider: This is an incredibly important question. So, number one, I mean, we were happy to see the directionality of our preliminary data be correct. But I do think that neuropathy is a very complicated toxicity, and it's probably a multigenic effect, and it probably is also impacted a lot by a variety of clinical factors. So some of the future work we'll be doing is looking at polygenic risk scores and other known genes that may be impactful, and also melding that with a number of really important clinical variables, because I still think we have the potential to predict this ahead of time. Shannon Westin: I know that this was such a patient driven topic, really focused on the patient experience and how to improve not only survival outcomes, but also toxicities and quality of life. Can you speak a little bit about the role of patients in the design of this trial, and maybe with helping it be as successful as it was with accrual? Dr. Bryan Schneider: Yeah. This has truly been one of the most exciting projects I've ever embarked on, and largely because of the incredible team atmosphere and contributions by so many people. Real thanks to the late Worta McCaskill-Stevens and also the late Edith Mitchell, who were two really fundamental disparities experts who really helped motor this trial to where it was. And also our patient advocates and the community at large really were part of the design and part of this from the very beginning, all the way through the publication, I think, have made it a clinically relevant study, and one that I think we're all very proud of. Shannon Westin: Is paclitaxel typically, what is the go-to? Or are more people using, let's say, docetaxel? Dr. Bryan Schneider: I think it depends a little bit on the disease setting and type. And again, is a function of historical clinical trials. One of the pivotal trials, E1199, actually compared a number of these. So it compared weekly paclitaxel to every three week paclitaxel to weekly docetaxel to every three week docetaxel in a two by two design. And essentially the conclusion there is that weekly paclitaxel and every three week docetaxel both outperformed what at the time was a standard of care, every three week paclitaxel. Now, weekly paclitaxel, at least through ECOG-ACRIN, has been adopted as kind of the standard reference therapy and schedule of choice, but largely because of the side effect profile. And again, this is based predominantly on white patients, where the tolerability is much better. Shannon Westin: Well, I mean, I think that this leads to really great information around how we're designing these trials and how we're potentially making those differences. What are your next steps here? Dr. Bryan Schneider: So I think one of the things this clinical trial did was first validate that we do see high rates of peripheral neuropathy in Black patients with breast cancer. This was a prospective study using both physician and patient adjudicated variables. So I think this is a really nice validation that this is a problem in this population. I think it also shows us that docetaxel is probably a more tolerable drug for black patients with breast cancer. The goal, though, I think in our future work, is really going to try to bring equity in terms of outcome and side effects. So we're working with ECOG-ACRIN now on our second trial, where really the primary endpoint is going to be to nullify the disparities and try to bring equity in terms of toxicity. One of the other pieces of work we're really excited about is we're doing some ex vivo work. So from patients in EAZ171, we have a blood stick where we're taking white blood cells and differentiating those into peripheral neurons. And here we're hoping to look at really important changes in both gene expression and epigenetics that might lead us to a little bit deeper understanding of the mechanism of the disparities in neuropathy, maybe what's causing some of the neuropathy. And we hope ultimately, these may lead to nice drug targets to help prevent or treat neuropathy down the road. Shannon Westin: Those are some really great ideas. The other thing that really caught my eye around your findings was what you all found regarding the physician reported and patient reported toxicity. I'd love for you to summarize that, because I think that's always a concern as well. Dr. Bryan Schneider: Historically, I think we recognize that physicians probably underreport side effects. And so we felt, and our team felt, that having patient reported outcomes would be a really critical piece to this study. What was fairly astonishing to me, if you look at the CTCAE, both patient and physician reported outcomes, they were actually pretty similar. And I think what this is a testament to is if physicians are actually thinking about the side effect, they do a pretty good job of predicting it. Now, one thing we're looking very forward to is that we have a long term follow up out to three years. So it'll be interesting to see if physicians continue to pay close attention to neuropathy, because I know the patients will be. So we'll be looking at the discordance at these longer term follow up time points as well. Shannon Westin: Well, great. This is such incredible work, and I'm like literally taking notes to get in touch with people I know that do this type of work and gynecological malignancies because I think that this is going to have far reaching consequences. So just thank you so much for taking the time to review this and congratulations on the JCO publication and ASCO presentation. It's very well deserved. Dr. Bryan Schneider: Thank you Dr. Westin.

Dr. Shaalan Beg and Dr.Mohamed Salem discuss key abstracts that will be presented at the 2024 ASCO Annual Meeting, including hypoxia-response CAR T- cell therapy for solid tumors, GPC3-specific CAR T- cell therapy in hepatocellular carcinoma, and the promising efficacy of targeted therapies in GI cancers.  TRANSCRIPT Dr. Shaalan Beg: Hello and welcome to the ASCO Daily News Podcast. I am Dr. Shaalan Beg, your guest host of the podcast today. I'm an adjunct associate professor at UT Southwestern's Simmons Comprehensive Cancer Center. In today's episode, we'll be discussing some key abstracts in GI cancers that will be presented at the 2024 ASCO Annual Meeting. I'm delighted to welcome Dr. Mohammed Salem, a GI medical oncologist at the Levine Cancer Institute at Atrium Health, for this discussion. Our full disclosures are available in the transcript of this episode. Mohammed, it's great to have you back on the podcast. Dr. Mohamed Salem: Thank you, Dr. Beg. It's always a pleasure to be here. Thanks for having me.  Dr. Shaalan Beg: So we're seeing more and more exciting data emerge on the role of ctDNA in GI cancers. And that's a topic that we've covered fairly extensively on the podcast. This year, in Abstract 3513, investigators used a novel, highly sensitive HPV ctDNA assay to evaluate the clinical outcomes of HPV ctDNA status in people with localized anal cancer treated with chemoradiation. And we know that prior HPV infection is associated with 90% of anal cancers. Can you give us a summary of the study and why it's so important to the clinical care we're giving our patients today?  Dr. Mohamed Salem: Sure. So, as you already alluded to, in the current era of precision oncology or precision medicine in general, there is an effort to try to maximize treatment efficacy and minimize the side effects. We're trying to understand how to do that by developing more biomarkers. I think this was a very interesting study that was led by Dr. Morris of MD Anderson. As you mentioned, he tried to determine the correlation between that circulating tumor DNA at different timelines and also associated that with the relapse. Obviously, as we all know, HPV infection is linked to about over 90% of anal cancers, and anal cancer is increasingly common in the U.S.  The study design includes patients from stage 1, 2, and 3 anal cancer treated with curative intent concurrent chemo radiation and the plot sample to collect circulating DNA was taken at five weeks of treatment and then at various intervals, including 3months, 6  months, 9 months and 12 months, to detect the HPV circulating DNA. And the analysis was done to correlate detection of circulating DNA with a relapse.  So what they observed is after collecting the samples at the end of the treatment, which is 5 weeks, followed by 3 months, 6 months, 9 months, and 12 months following treatment using the correlation between the detection of circulating tumor DNA as well as the recurrence rate, they were able to identify that about 22% was seen at 5 weeks, 13% was seen at three months, then 10% was seen at 6 months, and 0% actually was seen at 12 months. In the final analysis, they concluded that detection of circulating DNA at 3 months was significantly associated with a relapse rate of those patients. And also, they looked at the baseline stage, T stage, end stage, age and other perhaps prognostic factors. But the clinical implication of that trial is this finding supports the potential of integrating now the circulating DNA analysis and routine post-treatment surveillance, which hopefully will help us identify those patients with high risk of relapse and whether they can be treated with adjuvant therapy  in context-free drug trial or even like more close surveillance. Obviously, this is a very novel study, so it needs validation. Also, we need to understand more about the platform used because with the immersion technology and how fast this field is moving, I think it's important to look at this platform or other platforms. I think as a concept it's very interesting and hopefully will help us to identify patients with higher risk. So, I'm looking forward to hearing the full presentation. Dr. Shaalan Beg: Moving on to colorectal cancer, Abstract 3514 is a trial of hypoxia-responsive CEA CAR T-cell therapy for people with heavily pretreated solid tumors where this was administered intraperitoneally or intravenously. And you know, as a solid tumor oncologist or GI oncologist, we've been watching the hematologic space evolve so dramatically in the last five years with cellular therapies that it's exciting to see these CAR T-cell approaches being applied in solid tumors with some results. So can you talk about this study and whether you think it will influence clinical practice?  Dr. Mohamed Salem: Of course, I'm actually very excited to see this study because as you mentioned, CAR T-cell therapy has been utilized in hematological malignancies for the last several years and in fact it's becoming a center of care. As you know, it's very effective in certain tumors. Unfortunately, we did not see a similar result in solid tumors thus far. I know we are trying to make progress, but we are definitely not seeing the same efficacy in solid tumors. And also, of course, in CRC and many other tumors, we need more target options, so I was very excited to see this abstract. And I want to give a little bit of background why this abstract is important. Many solid tumors have a low oxygen level environment, hypoxia obviously, which can impact the effectiveness of CAR T therapy. So hypoxia can suppress the immune response, leading to poor performance of the immune cells like the T cell within the tumor. The investigators, to overcome that challenge, meaning hypoxia impacting the efficacy of the T cell, they were actually able to engineer a CAR T cell to be hypoxia responsive. And what does that mean? That the cells are designed to become more active in low oxygen conditions, which is more difficult in many of the solid tumors. The reason that's very interesting is because, one, it reduces exhaustion of the T cell, meaning like when you have the T cell active all the time, they get exhausted. So when you have the T cell in the resting state, until they reach the tumor environment and they get activated by the hypoxia status, now you reduce the expulsion of the T cell. But also that one overcomes the resistance. So once activated in the tumor hypoxic environment, this CAR T cell shows increased efficacy in targeting and killing the cancer cell.  Based on that concept, the investigators conducted a phase 1 dose escalation study in solid tumors. So this was a phase 1 open label group escalation study involving patients with tumor suppressed CEA and also had relapsed refractory second line treatment. The trial actually included 2 routes of administration, which I think was very interesting – IV versus intraperitoneal, IP, way of administration. And they enrolled about 40 patients between June of 2022 and January 2023. And 35 patients had colorectal cancer, 3 patients had gastric cancer, and 2 patients had non-small cell lung cancer. Overall, there was no surprising safety data. In terms of side effects, it was largely macrocystis, colitis. Unfortunately, they had 1 treatment that did not finish. But the interesting feature was the efficacy of that concept was demonstrated and in fact they were able to see more disease response and control at this rate with IP infusion, which I think is a very novel approach. I would look forward to trying and looking into this kind of delivery, especially in CRC and other tumors. Dr. Shaalan Beg: Because we've known that historically managing disease intraperitoneally has been challenging with cytotoxic chemotherapies and even surgical approaches that have been deployed can be fairly morbid as well. So looking at novel delivery mechanisms can help us understand, maybe be able to manage side effects of treatments in different ways and open doors for treatment in diseases that otherwise we couldn't manage. So definitely a very novel and exciting approach on this study.  Dr. Mohamed Salem: I agree. I think the idea of administering an IP route is a very interesting idea.   Well, Shaalan, there is another study in CRC, Abstract 3515. This is the first human study of ABBV-400, cMET–targeting antibody-drug conjugate in advanced solid tumors. Can you tell us about this promising data? Dr. Shaalan Beg: Yeah, so we've known that cMET is a very relevant biomarker across many cancers, particularly colorectal cancer, and it is overexpressed in a fairly large proportion of multiple diseases. But there hasn't been an effective regimen that has been found to be tolerable to target this specific biomarker. In this study, the investigators are evaluating an antibody drug conjugate, which takes the cMET targeting antibody telisotuzumab and conjugates it to a novel topoisomerase one inhibitor payload. And there's a phase one study that enrolled people across multiple different tumor types. This was presented at ASCO 2023. And this year, the investigators are coming in and giving the results of a colorectal cancer cohort within that study. Patients were enrolled in the dose escalation phase, and in the dose expansion phase, there were 122 colorectal cancer cases; so a fairly healthy size colorectal cancer population. And the median number of prior lines of therapy was 4, which is fairly consistent with what we would expect in our clinical population for people with colorectal cancer. So what they found in terms of efficacy is that the response rates, the confirmed overall response rates, were between 15 and 20%, depending on what dose of the medication the patients had received. They enrolled people regardless of cMET expression and then evaluated the response based on a higher or lower cMET expression. And those with higher cMET expression had an overall response rate of >30%, while those with lower cMET expression had a response rate of 10 to 15%. So they still had a response rate, which for fifth-line colorectal cancer is something to be aware of and it could be a marker of more significant clinical activity than other treatments that are out there.  And with the antibody drug conjugates, it's also important for us to keep an eye on the side effect profiles because a lot of these agents can have distinct side effect profiles that otherwise we wouldn't be familiar with. And in this study, 64% of participants had a grade 3 or above treatment emergent adverse events, and 41% had serious adverse events. So definitely something to think about. And most of these were hematologic toxicities, 30% had grade 3 or worse anemia. Neutropenia was seen, in grade three and above, was seen in 25%, leukopenia or grade three and above was seen in 12%, and thrombocytopenia again around 12%. And the non-hematologic toxicities were nausea, fatigue, vomiting and diarrhea. There was some interstitial lung disease, pneumonitis, which was seen in 7% of the total population, of which 2% had grade three or above. So definitely something to think about. From my perspective, I really am excited about this presentation because we're seeing evidence of clinical activity focused on cMET for refractory colorectal cancer compared to other agents that are out in the market. If this pans out in future studies, it could definitely change the way we deliver our treatments. Dr. Mohamed Salem: I totally agree that we actually need more therapy for those patients. And I'm not surprised that the myelosuppression, as you mentioned, was in fifth-line treatment. So this patient had large exposure to cytotoxic agents before.   So, looking at CAR T once more, there is a very interesting Abstract 4019, which is a study of C-CAR031, a GPC3-specific TGFβRIIDN armored autologous CAR T, in patients with advanced hepatocellular carcinoma (HCC). What are your key takeaways from this study, Shaalan? Dr. Shaalan Beg: This is a first-in-human study. It enrolled people with advanced HCC who failed on one or more lines of prior therapy and they were given one single infusion of C-CAR031 after standard lymphodepletion and they enrolled 24 patients across 4 dose levels. If we look at the overall response rate, 50% of the 22 people who were eligible for response assessments had a partial response. This response rate varies based on the dose level itself and the investigators claim a 90% disease control rate. So definitely when we think about standard treatments for hepatocellular cancer after first line therapy, this is something which will catch a lot of people's attention. Again, with CAR T-cell therapy, we need to be aware of the risk of potential toxicities. There were no dose limiting toxicities and CRS or cytokine release syndrome was observed in 91% of patients, while a very small proportion, about less than 5%, had grade three CRS. Most of the side effects here were, again, lymphocytopenia, neutropenia, thrombocytopenia, and some transaminitis in 16% of patients. They did see tumor reduction in 90%, not only in the intrahepatic disease, but also in the extrahepatic disease. And again, these are people who had BCLC stage C disease. So this included people with hepatic and extrahepatic metastases. And in terms of prior lines of therapy, 96% of patients had either received immune checkpoint inhibitors and TKIs.  If we think about how some other immune therapy regimens are being developed in the GI cancer space, there is some indication that liver lesions may respond differently compared to extra hepatic disease. So in this case, they saw responses in both scenarios, which makes it very exciting, because even though we've seen many approvals of TKIs and immunotherapy, anti-androgenic therapy in hepatocellular cancer, the treatment of these patients is still extremely difficult because of their underlying hepatic dysfunction. And it'll be very interesting to see how this treatment unfolds.  Dr. Mohamed Salem: You summarized it very well, Shaalan. I echo your thoughts. What is also interesting about that study, it's actually targeted at the GPC strain, which is prevalent in HCC but not normal tissue, which goes back to your comment about the toxicity, and hopefully we can also manage treatment in the context of underlying liver disease.  Dr. Shaalan Beg: I guess it's fair to say that we're both very excited to see what's ahead in GI cancers at the Annual Meeting.   Mohamed, thanks as always for sharing your great insights with us on the ASCO Daily News Podcast.  Dr. Mohamed Salem: Thank you all for having me, and I'm looking forward to meeting you and all our colleagues in Chicago in a couple of weeks. Dr. Shaalan Beg: And thank you to our listeners for your time today. You'll find links to the abstracts discussed today in the transcripts of this episode. I'll be back to cover late breaking abstracts and other key advances in GI oncology after the annual meeting, so please join me for more key insights from ASCO24 and on the ASCO Daily News Podcast.

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. Vamsi Velcheti and Nathan Pennell discuss key lung cancer abstracts from the 2024 ASCO Annual Meeting, including data from LUMINOSITY and ADAURA, novel therapies in KRASG12C-mutant advanced NSCLC, and the need for effective adjuvant therapies for patients with rare mutations. TRANSCRIPT Dr. Vamsi Velcheti: Hello, I am Dr. Vamsi Velcheti, your guest host for the ASCO Daily News Podcast today. I'm a professor of medicine and director of thoracic medical oncology at Perlmutter Cancer Center at NYU Langone Health. Today, I'm delighted to welcome Dr. Nathan Pennell, the co-director of the Cleveland Clinic Lung Cancer Program and vice chair of clinical research at the Taussig Cancer Center. Dr. Pennell is also the editor-in-chief of the ASCO Educational Book. Dr. Pennell is sharing his valuable insights today on key abstracts in lung cancer that will be presented at the 2024 ASCO Annual Meeting. You'll find our full disclosures in the transcript of the episode.  Nate, it's great to have you here on the podcast. Thank you for being here. Dr. Nathan Pennell: Thanks, Vamsi, for inviting me. I'm always excited for the ASCO Annual Meeting, and we have a tremendous amount of exciting lung cancer abstracts. I know we're not going to discuss all of them on this podcast, but even exciting Plenary presentations coming up.  Dr. Vamsi Velcheti: So, one of the abstracts that caught my attention was Abstract 103, the LUMINOSITY trial, which will be presenting the primary analysis at the meeting. So, there's a lot of buzz and excitement around ADCs. Can you comment on this abstract, Nate, and what are your thoughts on key takeaways from this abstract?  Dr. Nathan Pennell: Absolutely, I agree. This is really an exciting new potential target for lung cancer. So historically, when we think about MET and lung cancer, we think about the MET exon 14 skipping mutations which are present in 3% or 4% of adenocarcinoma patients. And we have approved tyrosine kinase inhibitors, small molecule inhibitors that can be very effective for those. What we're talking about here is actually an antibody drug conjugate or ADC telisotuzumab vedotin, which is targeting the MET protein over expression in non-squamous EGFR wild type advanced non-small cell lung cancer. The LUMINOSITY was a single arm, phase 2 study of teliso, and first of all, I think we have to define the patient population. So, these were MET over expressing non-small cell lung cancer by immunohistochemical staining. So, it included both what they considered MET high expression and MET intermediate expression, both of which had to be 3+ IHC positive on 25% to 50% of cells in the intermediate and 50% or higher in the high expressing group. They were treated with the ADC and had pretty promising results, a response rate of 35% in the MET high group and 23% in the intermediate group. Duration of response at nine months and 7.2 months in those two groups, and the PFS was five and a half and six months. So I would say in a previously treated population, this was relatively promising and potentially defines a completely new and unique subgroup of biomarker defined patients. So, Vamsi, I'm curious, though, if this ends up moving forward to further development, what your thoughts are on adding yet another biomarker in non-small cell lung cancer? Dr. Vamsi Velcheti: Yeah, I think it's certainly exciting. I think for this population, we really don't have a lot of options beyond the second line, and even in the second line, docetaxels are low bar. So,I think having more options for our patients is certainly outcome development. And I think MET IHC is relatively easy to deploy in a clinical setting. I think we already test for MET PD-L1 IHC routinely, and now recently, as you know, HER2 IHC given approval for ADCs, HER2 ADCs there in that space. So, I think from a technical standpoint, I don't see a big barrier in terms of adding an additional IHC marker. And usually, the IHC testing is pretty quick. And I think if you have a therapeutic approval based on IHC positivity, I think certainly from an operational standpoint, it shouldn't be a very complicated issue. Dr. Nathan Pennell: Yeah, I agree. This is cheap. It's something that can be done everywhere in the world. And as you said, in addition to diagnostic IHC, we're already looking at PD-L1, and probably moving towards doing that for HER2. This is really wonderful that we're moving into kind of the era of the ADCs, which is opening up a whole new therapeutic group of options for patients. Dr. Vamsi Velcheti: So, the other abstract that caught my attention was like, the Abstract 8005. This is the molecular residual disease MRD analysis from the ADAURA trial. The ADAURA trial, as you all know, is the trial that led to the FDA approval of adjuvant use of osimertinib in patients with EGFR mutant stage 1B through 3A non-small cell lung cancer. And in this trial, osimertinib demonstrated significant improvements in DFS and OS. And in this particular study, Abstract 8005, the authors looked at the role of MRD in predicting DFS in the study. And after 682 patients who were randomized, 36% of the patients had samples to look at MRD post- surgery. And in the trial the MRD status predicted DFS or event free survival at 36 months with a hazard ratio of 0.23. And the MRD status had a median lead time of 4.7 months across both the arms, both osimertinib and the placebo arm. So, suggesting that MRD could potentially identify high risk subgroups of patients post-surgery to tailor personalized approaches potentially in this population. So, Nate, in your practice, of course, we don't have a clinically validated approach yet to kind of use MRD in this setting, but if we have an option to use an MRD based assay, do you think that would potentially be an opportunity to perhaps escalate or de-escalate adjuvant strategies with TKIs in the adjuvant setting? Do you see value in using MRI assays post- surgery? Dr. Nathan Pennell: Yeah, I think this is a really important study because this is such an important topic around adjuvant targeted treatment. So, of course, ADAURA really changed how we treated people with EGFR mutant lung cancer who underwent surgical resection, because we know that the three years of osimertinib significantly improved disease-free survival and overall survival. But there's still a lot of questions being asked about, is that affordable? Obviously, we're putting a lot of resources into three years of treatment, and not everyone necessarily needs it. There may well be people who are cured with surgery alone and adjuvant chemotherapy. And then what about duration? Is three years enough? Do we need even longer treatment, or do we need shorter treatment? And up to date, we haven't really been able to tell people at risk of recurrence other than the pure odds-based risk based on their stage.   And the assay that was used in the ADAURA study was a personalized tumor informed assay based on the resected tumor. It's unclear to me whether this was just a subgroup of people that had this done or whether they tried to do it in all 600 patients and only, it looks like they were successful in about 32% of people. Maybe about a third were able to successfully have a tumor informed assay. So, the first question is, “Can you use this to help guide who needs treatment or not?” And I think what they showed was only about 4% of people in osimertinib arm in 12% had MRD positive at baseline after surgery. So probably, upfront testing is not really going to be all that helpful at determining who's at high risk and needs to be treated.   Interestingly, of those who were positive, though, most of them, or 80% of them, did go MRD negative on osimertinib. And what I found really interesting is that of those who did have a recurrence, 65% of them did have the MRD test turn positive. And as you mentioned, that was about five months prior to being picked up radiographically, and so you can pick them up sooner. And it also looks like about two thirds of recurrences can be identified with the blood test. So that potentially could identify people who are recurring earlier that might be eligible for a more intensive treatment. The other thing that was really interesting is of those who recurred in the osimertinib arm, 68% of them happened after stopping the osimertinib, suggesting that for the majority of patients, even those not necessarily cured, they seem to have disease control while on the osimertinib, suggesting that maybe a longer duration of treatment for those patients could be helpful. The problem is it still isn't necessarily helpful at identifying who those people are who need the longer duration of treatment. So, definitely an important study. I think it could be useful in practice if this was available clinically, especially at monitoring those after completion of treatment. I think as the sensitivity of these MRD assays gets better, these will become more and more important. Dr. Vamsi Velcheti: I think it's a little bit of a challenge in terms of standardizing these assays, and they're like multiple assays, which are currently commercially available. And I think the field is getting really complicated in terms of how you incorporate different assays and different therapeutics in the adjuvant space, especially if you're kind of looking at de-escalating immunotherapeutic strategies at the adjuvant setting, I think, makes it even more challenging. I think exciting times. We definitely need more thoughtful and better studies to really define the role of MRD in the adjuvant space. So, I guess more to come in this space. Dr. Nathan Pennell: Vamsi, I wanted to ask you about another really interesting Abstract 8011. This is a subgroup of the AEGEAN perioperative study for early-stage resected non-small cell lung cancer. This abstract is specifically looking at baseline N2 lymph node involvement in stage 2A-3B with N2 positive patients in an exploratory subgroup analysis. What are your key takeaways from the study?   Dr. Vamsi Velcheti: I felt this was a very interesting abstract for a couple of reasons. As you know, this is the AEGEAN trial, the phase 3 trial that was reported earlier last year. This is a perioperative study of durvalumab plus new adjuvant chemotherapy versus new adjuvant chemotherapy alone and adjuvant durvalumab plus placebo. The study obviously met its primary endpoint, as we all saw, like the event-free survival. And here in this abstract, the authors present an exploratory subgroup analysis of patients who had N2 lymph node involvement prior to study enrollment. So, in this study, they were focusing on perioperative outcomes. And one of the issues that has come up multiple times, as you know, in a lot of these preoperative studies, is the impact of neoadjuvant chemo immunotherapy on surgery or surgical outcomes. And consistently, across a lot of these trials, including the CheckMate 816, about 20% of patients don't end up making it to surgery. So in that light, I think this study and the findings are very interesting. In this study, they looked at patients who had N2 nodal involvement and of the patients with N2 nodal involvement, the surgical operability or the number of patients who completed surgery was similar in both the groups. So, there was no significant difference between patients who received durva versus chemotherapy and also among patients who had N2 subgroup who had surgery, similar proportions of durvalumab and placebo arms had open versus minimally invasive versus pneumonectomy. So durvalumab didn't have a negative impact on the type of surgery that the patients had at the time of surgery. So overall, the findings were consistent with other trials, perioperative trials that we have seen. So, the surgical outcomes were not negatively impacted by adding immunotherapy in the neoadjuvant perioperative space. So, this is consistent with other trials that we have seen. And also, the other issue, Nate, I'd like to get your opinion on is, across the board, in all the perioperative trials we have seen that about 20% of the patients actually don't end up making it a surgery. And of course, most of these perioperative trials, a lot of these patients are stage 3 patients. And my take on this was that there's probably a little bit of a patient selection issue. We generally tend to err on the side of operability when we have a stage 3 patient discussed in the tumor board, sometimes feel like the patient may downstage and could potentially go to surgery. But even in the real world, in stage 3 operable patients, what proportion of patients do you think don't end up going to surgery? Dr. Nathan Pennell: That is such an important question that I don't think we have the best answer to. You're right. All of these perioperative studies have a relatively high- sort of 20% to 30% of people who enroll on the studies don't necessarily go to surgery. And I don't think that they've done as great a job as they could in all of these trials describing exactly what happens to these patients. So in the real world, obviously not everyone would be fit enough to go to surgery or might progress in the time between when they were diagnosed and the time as planned for surgery. But probably more of them would go to surgery if they weren't getting neoadjuvant treatment, because that would be their initial treatment. The question is, of course, is that the right choice? If someone gets 12 weeks or nine weeks of neoadjuvant treatment and then a restaging scan shows that they've had progression with metastatic disease, are those really the people that would have been optimally treated with surgery upfront, or would they just have had recurrence on their first postoperative scan? So, it's really an important question to answer. I think the bigger one is, is the treatment preventing them through toxicity from going to treatment? And I think the studies have generally felt that few patients are missing out on the option of surgery because of toxicity being caused by the IO. And in the AEGEAN study, for example, in this subgroup, a slightly numerically higher percentage of patients in the durvalumab arm actually underwent surgery compared to those who got neoadjuvant chemo. So, it doesn't seem like we're necessarily harming people with the neoadjuvant treatment. But I know that this is a concern for patients and doctors who are undergoing this approach. Dr. Vamsi Velcheti: Definitely, I think having multiple data sets from perioperative trials, looking at the relative impact of IO on the safety and the nature of the surgery is going to be important, and this is a very important study for that reason. Dr. Nathan Pennell: Can I ask you another thing that I thought really interesting about this particular one is they looked at the difference between those with single station N2 and multi station N2. And I know this is one of those, should we be operating on people who have multi station N2 disease? And the AEGEAN study did include people who had multiple N2 stations where perhaps in the pre-IO era, these would have been treated with definitive chemoradiation and not surgery at all. But the disease-free survival hazard ratio was essentially the same for multi station N2 as it was in the overall population. So, has that changed the way we're approaching these patients in these multidisciplinary discussions? Dr. Vamsi Velcheti: Absolutely, Nate. I think surgical operability is in the eye of the beholder. I think it depends on which surgeon sees the patient or how the discussion goes in the tumor boards, as you know. Certainly, I think with this optionality of having a chemo IO option and potential for downstaging, kind of pushes, at least in our practice, more of these patients who are multistation, who would have otherwise gone down the chemoradiation route are now actually going through neo adjuvant chemo IO and with the hope that they would make it to surgery. So, I think it's an interesting change in paradigm in managing our locally advanced patients. So, I think it's certainly interesting, but I guess to your point, there clearly are some patients who probably should just have chemoradiation upfront, and we may be kind of like delaying that definitive chemoradiation approach for at least a subset of patients. So, at the end of the day, I think it's a lot of clinical decision-making and I think there's going to be a little bit of art to managing these patients and it's going to be really hard to define that population for a clinical trial.  Dr. Nathan Pennell: Yeah, clearly, multidisciplinary discussion, still very important for earliest age non-small cell lung cancer patients. If we move back to metastatic lung cancer, let's talk about Abstract 8510 looking at one of our newer, exciting biomarkers, which are the KRASG12Cmutant non-small cell lung cancer. So this is a study of a second generation KRASG12Cinhibitor, olomorasib, which was combined with pembrolizumab, the anti PD-1 antibody, in patients with advanced KRASG12C mutant non-small cell lung cancer. This is something that has been tried before with first generation G12C inhibitors, with some concerns about how safe it was to do that. So, Vamsi, what did you learn from this abstract? Dr. Vamsi Velcheti: Definitely, I think one of the concerns that we've had in other trials is like the cumulative toxicity of adding checkpoint inhibition to G12C inhibitors, especially the sotorasib CodeBreaK trial, where we see increased rates of grade 3, 4 transaminitis. So, it is encouraging to see that some of the newer agents have less of those issues when it comes to combining the checkpoint inhibition. So especially with KRASG12C, as you know, these are patients who are smokers, and often these are patients who have high PDL-1 could potentially also benefit from immunotherapy. In order for these KRASG12C inhibitors, in order to move these targeted therapy options for these patients to the front line, I do think we need to have substantial comfort in combining the checkpoint inhibitors, which is a standard treatment approach for patients in the frontline setting. I think this is exciting, and I think they're also like, as you know, there are other KRASG12C inhibitors also looking to combine with checkpoint inhibition in the frontline settings. So, we'll have to kind of wait and see how the other agents will perform in the setting. Dr. Nathan Pennell: Yeah, I completely agree. I think this is such an important area to explore specifically because unlike our other targeted oncogenes like EGFR and ALK, we have multiple options for these patients, both immunotherapy and targeted treatments. And if we could think about sequencing them or even combining them and if it could be done safely, I think that would be well worth investigating. There still was significant toxicity in this trial; 30% of people had diarrhea, even at the reduced dose, and there was transaminitis at sort of about 20% or so, although probably at a manageable level. But the response rate was really quite promising. And these are all previously IO and mostly G12C TKI pre-treated patients still had a response rate of 63%. And in those who were naive to IO and TKIs, it was 78% response rate. So, if it could be done safely, I think it's definitely worth pursuing this in further trials. Dr. Vamsi Velcheti: And also, there's some data, preclinical data, like looking at G12C inhibition. And also we have known with MET inhibition for a long time that it could potentially augment immune responses and could be having some synergistic effect with IO. So, we'll have to wait and see, I think. But safety is really the top in mind when it comes to combining these agents with checkpoint inhibitors. So, it's really encouraging to see that some of the newer agents may be more combinable IO. Now moving on to the next abstract, and moving on to, again, the early-stage setting. So, Abstract 8052 from our colleagues in Princess Margaret reported outcomes in early-stage non- small cell lung cancer in patients with rare targetable mutation. This is actually becoming increasingly more relevant because we are seeing at least, like with the ALINA data, with the ALK and EGFR, now with ADAURA, we know that these patients don't benefit with adjuvant immunotherapy, especially some of these rare oncogene living mutations, other than like G12C. So I always struggle with this. When you have early-stage patients, with, let's say, a ROS or a RET, where we just don't have data, and we know that those are poor actors because biologically these are aggressive tumors. So, there's a really odd clinical question to ask in terms of, what is the role of adjuvant immunotherapy? Of course, this trial and this abstract are not really addressing that. But what is your take on this abstract? If you could just summarize the abstract for us. Dr. Nathan Pennell: Sure. Well, I think this is incredibly important, and this is an area near and dear to my own heart. And that is, of course, the whole landscape of how we manage early-stage patients has changed with both ADAURA, because we now have effective treatment in the adjuvant setting for EGFR mutant patients, and now more recently with the ALINA trial for adjuvant alectinib for ALK positive patients now being FDA-approved. So, what that means is we actually have to be testing people at diagnosis even before they would be getting adjuvant treatment, and potentially before even surgery to look for these targets. We need the PD-L1 status, we need EGFR and ALK. And if you're going to be looking at these biomarkers, I think there is a reasonable argument to be made that you should be doing broad testing for all of the targetable oncogenes in these patients. There are some studies suggesting that there's value to this and identifying them for treatment at the time of recurrence. But we also know that these patients are at high risk of recurrence and probably need to be investigated, at least in trials for the adjuvant setting. So, this particular study looked at 201 resected, mostly adenocarcinoma patients, and then they basically sequenced them for all of the targeted oncogenes. And they were quite common, perhaps even more common than you might expect in an advanced population. So, 43% of them had KRASG12C mutations, 13% had EGFR Exon 20 mutation, ERBB2 or HER2 mutations found in 11%, MET mutations in 10%, ALK in 7%, ROS1 in 6%, BRAF in 5%, and RET in 2%. So quite common to find these targetable oncogenes in this particular population, perhaps a somewhat biased population at Princess Margaret Hospital, but very common. And then they looked at the outcomes of these patients without targeted adjuvant treatment. And what they found was there was a very high rate of recurrence. So, relapse-free survival was pretty high in these patients across different stages, and generally their prognosis was worse than the more common KRASG12C patients. Most of these, in particular the HER2 mutant patients, seem to have a significantly worse relapse free survival. Interestingly enough, though, that did not carry over to overall survival. Overall survival was better in those who had targetable oncogenes. And my guess is that that probably had to do with the availability of targeted treatments at the time of recurrence that may have impacted overall survival. But I do think that this particularly highlights the need, the unmet need for effective adjuvant treatment in these patients. And most of them, with the exception of KRAS and perhaps BRAF, perhaps MET unlikely to benefit from adjuvant immunotherapy, as you mentioned. And so, I think we really need to be investing in trials of adjuvant targeted treatments in these populations.  Dr. Vamsi Velcheti: Yeah, this is an area that we really don't have a lot of data. But Nate, a question for you. So tomorrow you have a patient with RET fusion, stage 2, N1 disease. What would you do? Would you offer them an adjuvant RET inhibitor? Dr. Nathan Pennell: I think I would search really hard for a trial to give them access. But if you really want to know what I think, and I'm usually willing to tell people what I think, I think the proof of concept is there. I think we know that in the setting of highly effective and very tolerable adjuvant targeted treatment in the EGFR space with osimertinib, in the ALK space with alectinib, if anything, drugs like selpercatinib and pralsetinib in RET fusion positive lung cancer in the advanced setting are just as well tolerated and easily as effective and long lasting. And so, I think if you did a trial and they are doing trials looking at these drugs in the adjuvant space, almost certainly you're going to see the same really dramatic disease-free survival benefit from these treatments, which, at least in the EGFR space, seems to have translated into an improvement in overall survival. And so if I had a stage II or a resected stage 3, especially a RET fusion positive patient today, I would definitely talk to them about off-label use of a RET inhibitor if I could not find a trial. Now, I understand that there are going to be reimbursement issues and whatnot associated with that, but I think the extrapolation is worth discussing. Dr. Vamsi Velcheti: Yeah, I think it's really challenging because some of these fusions are so rare and it's hard to really do large adjuvant trials for some of these rarer subgroups.

Doctors Vamsi Velcheti, Sandip Patel, and Michael Zervos discuss recent updates on the management of early-stage non-small cell lung cancer (NSCLC), including the optimization of neoadjuvant and adjuvant treatment options for patients and the role of surgery in the era of targeted therapy and immuno-oncology in lung cancer. TRANSCRIPT Dr. Vamsi Velcheti: Hello, I'm Dr. Vamsi Velcheti, your guest host for the ASCO Daily News Podcast today. I am a professor of medicine and director of thoracic medical oncology at the Perlmutter Cancer Center at NYU Langone Health. On today's episode, we'll be discussing recent updates on the management of early-stage non-small cell lung cancer (NSCLC), including the optimization of neoadjuvant and adjuvant treatment options for our patients, and the evolving role of surgery in the era of targeted therapy and immuno-oncology in lung cancer.  Today, I am delighted to be joined by two renowned experts in this space, Dr. Sandip Patel and Dr. Michael Zervos. Dr. Patel is a professor of medicine and a medical oncologist specializing in lung cancer at UCSD. Dr. Mike Zervos is the clinical chief of the Division of Robotic Thoracic Surgery and Director of General Thoracic Surgery at NYU Langone. Our full disclosures are available in the transcript of this episode, and disclosures relating to all episodes of the podcast are available at asco.org/DNpod. Dr. Patel and Dr. Zervos, it's a great honor to have you on the podcast today. Welcome aboard. Dr. Sandip Patel: Great to be joining you.  Dr. Vamsi Velcheti:  Let's get started with Dr. Patel. As you know, over the last decade we've had dramatic advances in systemic therapy options for patients with metastatic non-small cell lung cancer, in both the realms of targeted therapy and immunotherapy. These have significantly improved outcomes for our patients with metastatic lung cancer. What's exciting is that more recently, we've seen the incorporation of these agents, both targeted therapies and immunotherapies, in early-stage non-small cell lung cancer. Dr. Patel, can you tell our listeners about these exciting recent advances and why do you think it's so important to incorporate these personalized systemic therapy options for our early-stage patients? Dr. Sandip Patel: I think it's a great point and a great question. And so, I think one thing to understand is that non-small cell lung cancer is actually multiple diseases. We give it one name based on how it looks under the microscope, but the vast majority of our advances to improve outcomes for patients have come from our ability to understand specific subgroups.  Many of our therapies have had activity in the advanced setting. We have our patients with metastatic or more widespread disease, which naturally led to the thought that could we utilize these therapies in earlier stage disease and potentially increase the rate of cure for many of our patients, lung cancer being the most common cancer killer worldwide. And so to your point, trying to understand how to best treat a patient really involves personalized medicine, typically driven by understanding the genomic profile of their tumor and two of the genes that have graduated from being tested for in the metastatic setting and now in the localized setting are EGFR and ALK. And these in particular are mutations that confer sensitivity to small molecule inhibitors, EGFR with osimertinib, ALK in the localized setting with alectinib based on the data that we've seen.  And so, one of the areas that's been particularly exciting is our ability to maximize a patient's chance for durable remissions by integrating these therapies after surgery, after chemotherapy when appropriate, and continuing generally for a finite amount of time, two to three years depending on the agent in the study we're discussing for these patients. Additionally, immunotherapy, which has revolutionized our treatment of patients with metastatic disease, may be particularly well-suited for the localized setting of non-small cell lung cancer as well. Dr. Vamsi Velcheti: Excellent points, Sandip. You're absolutely right, in the metastatic setting, we've all come to accept molecular testing, sequencing, and biomarker profiling as a standard, but unfortunately, that hasn't quite yet percolated into the early-stage setting. Can you talk about some of the challenges that we face as we have these therapeutic options available now for more early-stage patients? Dr. Sandip Patel: So, I think there are 3 flavors of localized therapy in non-small cell lung cancer. One is the advanced, unresectable stage 3, for which the approach is often concurrent chemo-radiation followed by some form of consolidated therapy. We're about to hear the results of LAURA, which is the study looking at EGFR-mutated non-small cell lung cancer.  For other patients, historically, the treatment has been durvalumab, an anti-PD-L1 directed immunotherapy. The other two are operative treatment of localized cancer: adjuvant treatment after surgery, or neoadjuvant or perioperative, in which chemoimmunotherapy begins before surgery. And testing depends on the settings. For the stage 3 patient who's likely getting concurrent chemo-radiation, they may have a very small amount of tissue, and so often these are done by pulmonary EBUS biopsies and that's how we pathologically confirm that advanced stage 3B. There may not be a lot of tissue available for molecular testing. In fact, if you look at the PACIFIC analysis, just looking at PD-L1, which is just an IHC off a single slide, a third of patients weren't able to even get a PD-L1, let alone a genomic result. And so, I think that's one of the areas of LAURA that's going to be particularly interesting to see as we try to implement it into our practice after seeing the full data.  I think in the adjuvant setting, we're lucky because our surgeons, Dr. Mike Zervos here, will get us a large amount of tissue in the surgical resection specimen, so we tend to get enough tissue to do genomics while they're under chemotherapy, there tends to be time to wait for their genomic result. Where this really gets complicated is in the neoadjuvant or perioperative setting, where time is everything.  The most important thing we can do for a patient in the localized space is get them to the operating room, get them started on radiation, their curative local modality, and that's where we have a time pressure but also a sample pressure because that is a diagnostic biopsy. It's a very small piece of tissue. Initially, there are multiple stains that have to be done to identify this lung cancer as opposed to another tumor. And so that's an area that I think we're going to need additional approaches given that cell-free DNA tends to have lower yield in lower stage disease in giving us a result. Dr. Vamsi Velcheti: Great points, Sandip. How do you deal with this issue in San Diego? The challenge is now we have a lot of trials, we'll talk about those neoadjuvant immunotherapy trials, but we know that immunotherapy may not be as effective in all patients, especially those with EGFR or ALK or some of these non-smoker, oncogene-driven tumors. So, we don't want to be giving patients treatments that may not necessarily be effective in the neoadjuvant space, especially when there is a time crunch, and we want to get them to surgery and all the complications that come with giving them targeted therapy post-IO with potential risk for adverse events. Dr. Sandip Patel: Absolutely. It is a great point. And so, the multidisciplinary team approach is key, and having a close relationship with the interventional pulmonary oncs, interventional radiology surgery, and radiation oncology to ensure that we get the best treatment for our patients. With the molecularly guided therapies, they are currently more on the adjuvant setting in terms of actually treating. But as you mentioned, when we're making a decision around neoadjuvant or perioperative chemo IO, it's actually the absence of EGFR now that we're looking for because our intervention at the current time is to give chemoimmunotherapy. Going back to the future, we used to use single gene EGFR within 24 hours, which was insufficient for a metastatic panel, but it often required five slides of tissue input. ALK can be done by IHC, and so some of these ‘oldie but goodie' pathologic techniques, and that pathologists, if I haven't emphasized, understanding what we're trying to do at a different context is so key because they are the ones who really hold the result. In the neoadjuvant and perioperative setting, which many of us favor, especially for stage 3A and stage 2B disease, understanding how we can get that result so that we can get the patient to the operating room in an expeditious way is so important. There is a time pressure that we always had in the metastatic setting, but I think we feel much more acutely in the neoadjuvant and perioperative setting in my opinion. Dr. Vamsi Velcheti: Fascinating insights, Dr. Patel.  Turning to Dr. Zervos, from a surgical perspective, there has been an evolution in terms of minimally invasive techniques, robotic approaches, and enhanced recovery protocols, significantly improving outcomes in our patients post-surgery. How do you see the role of surgery evolving, especially with the increasing complexity and efficacy of these systemic therapies? How do you envision the role of surgery in managing these early-stage patients, and what are the key considerations for surgeons in this new era? Dr. Michael Zervos: Thanks, Vamsi. Thanks, Sandip. Thank you for having me on the podcast. Obviously, it's an honor to be a part of such a high-level discussion. I have to say, from a surgeon's perspective, we often listen to you guys talk and realize that there's been a lot of change in this landscape. And I think the thing that I've seen is that the paradigm here has also changed. If we were having this discussion 10 years ago, a lot of the patients that I am operating on now, I would not be operating on. It really has been amazing. And I think the thing that stands out to me the most is how all of this has changed with neoadjuvant chemotherapy checkpoint inhibition. I think, for us as surgeons, that's really been the key. Whether it's CheckMate 816 or whatever you're following, like PACIFIC, the data supports this. And I think what we're seeing is that we're able to do the surgery, we're able to do it safely, and I think that the resectability rates are definitely high up there in the 90% range. And what we're seeing is pretty significant pathologic responses, which I think is really amazing to me.  We're also seeing that this has now shifted over to the oligometastatic realm, and a lot of those patients are also being treated similarly and then getting surgery, which is something that we would not have even thought of ever. When you look at the trials, I think a lot of the surgery, up to this point, has been done more traditionally. There's a specific reason why that happens, specifically, more through thoracotomy, less with VATS, and less with robotic. Sandip, I think you guys have a pretty robust robotic program at UCSD, so I'm sure you're pretty used to seeing that.   As you guys have become so much more sophisticated with the treatments, we have also had to modify what we do operatively to be able to step up to the plate and accept that challenge. But what we are seeing is yes, these treatments work, but the surgeries are slightly more complicated. And when I say slightly, I'm minimizing that a little bit.  And what's complicated about it is that the treatment effect is that the chemo-immune check inhibition actually has a significant response to the tumor antigen, which is the tumor. So it's going to necrose it, it's going to fibrose it, and wherever there is a tumor, that response on the surgical baseline level is going to be significant. In other words, there are going to be lymph nodes that are stuck to the pulmonary artery, lymph nodes that are stuck to the airway, and we've had to modify our approaches to be able to address that.   Now, fortunately, we've been able to innovate and use the existing technology to our advantage. Personally, I think robotics is the way we have progressed with all this, and we are doing these surgeries robotically, mainly because I think it is allowing us, not only to visualize things better, but to have sort of a better understanding of what we're looking at. And for that matter, we are able to do a better lymph node dissection, which is usually the key with a lot of these more complicated surgeries, and then really venturing out into more complicated things, like controlling the pulmonary artery. How do we address all this without having significant complications or injuries during the surgery? Getting these patients through after they've successfully completed their neoadjuvant treatment, getting them to surgery, doing the surgery successfully, and hopefully, with minimal to no morbidity, because at the end, they may be going on to further adjuvant treatment. All of these things I think are super important. I think although it has changed the landscape of how we think of things, it has made it slightly more complicated, but we are up for the challenge. I am definitely excited about all of this. Dr. Vamsi Velcheti: For some reason, like medical oncologists, we only get fixated on the drugs and how much better we're doing, but we don't really talk much about the advances in surgery and the advances in terms of outcomes, like post-op mortality has gone down significantly, especially in larger tertiary care centers. So, our way of thinking, traditionally, the whole intergroup trials, the whole paradigm of pneumonectomies being bad and bad outcomes overall, I think we can't judge and decide on current treatment standards based on surgical standards from decades ago. And I think that's really important to recognize.  Dr. Michael Zervos: All of this stuff has really changed over the past 10 years, and I think technology has helped us evolve over time. And as the science has evolved for you with the clinical trials, the technology has evolved for us to be able to compensate for that and to be able to deal with that. The data is real for this. Personally, what I'm seeing is that the data is better for this than it was for the old intergroup trials. We're able to do the surgery in a better, more efficient, and safer way. The majority of these surgeries for this are not going to be pneumonectomies, they are going to be mostly lobectomies. I think that makes sense. I think for the surgeons who might be listening, it doesn't really matter how you're actually doing these operations. I think if you don't have a very extensive minimally invasive or robotic experience, doing the surgery as open is fine, as long as you're doing the surgery safely and doing it to the standard that you might expect with complete lymph node clearance, mediastinal lymph node clearance, and intrapulmonary lymph node clearance. Really, I think that's where we have to sort of drive home the point, really less about the actual approach, even though our bias is to do it robotically because we feel it's less morbidity for the patient. The patients will recover faster from the treatment and then be able to go on to the next phase treatments. Dr. Vamsi Velcheti: In some of the pre-operative trials, the neoadjuvant trials, there have been some concerns raised about 20% of patients not being able to make it to surgery after induction chemo immunotherapy. Can you comment on that, and why do you think that is the case, Sandip?  Dr. Sandip Patel: Well, I think there are multiple reasons. If you look, about half due to progression of disease, which they might not have been great operative candidates to begin with, because they would have early progression afterwards. And some small minority in a given study, maybe 1% to 2%, it's an immune-related adverse event that's severe. So, it's something that we definitely need to think about. The flip side of that coin, only about 2 in 3 patients get adjuvant therapy, whether it be chemotherapy, immunotherapy, or targeted therapy. And so, our goal is to deliver a full multimodal package, where, of course, the local therapy is hugely important, but also many of these other molecular or immunologically guided agents have a substantial impact.  And I do think the point around neoadjuvant and perioperative is well taken. I think this is a discussion we have to have with our patients. I think, in particular, when you look at higher stage disease, like stage 3A, for example, the risk-benefit calculus of giving therapy upfront given the really phenomenal outcomes we have seen, really frankly starting with the NADIM study, CheckMate816, now moving on into studies like KEYNOTE-671, AEGEAN, it really opens your eyes in stage 3. Now, for someone who's stage 1/1b, is this a patient who's eager to get a tumor out? Is there as much of an impact when we give neoadjuvant therapy, especially if they're not going to respond and may progress from stage 1 and beyond? I think that's a reasonable concern. How to handle stage II is very heterogeneous. I think two points that kind of happen as you give neoadjuvant therapy, especially chemo-IO that I think is worth for folks to understand and this goes to Mike's earlier point, that is this concept if they do get a scan during your neoadjuvant chemo immunotherapy, there is a chance of that nodal flare, where the lymph nodes actually look worse and look like their disease is progressing. Their primary tumor may be smaller or maybe the same. But when we actually go to the OR, those lymph nodes are chock-full of immune cells. There's actually no cancer in those lymph nodes. And so that's a bit of a red herring to watch out for.   And so, I think as we're learning together how to deliver these therapies, because the curative-intent modality is, in my opinion, a local modality. It's what Mike does in the OR, my colleagues here do in the OR. My goal is to maximize the chance of that or really maximize the long-term cure rates. And we know, even as long as the surgery can go, if only 2 or 3 patients are going to get adjuvant therapy then 1 in 10, of which half of those or 1 in 20, are not getting the surgery and that's, of course, a big problem. It's a concern. I think better selecting towards those patients and thinking about how to make these choices is going to be hugely important as we go over. Because in a clinical trial, it's a very selective population. A real-world use of these treatments is different. I think one cautionary tale is that we don't have an approval for the use of neoadjuvant or perioperative therapy for conversion therapy, meaning, someone who's “borderline resectable.” At the time at which you meet the patient, they will be resectable at that moment. That's where our best evidence is, at the current time, for neoadjuvant or perioperative approaches.  Dr. Vamsi Velcheti:   I think the other major issue is like the optimal sequencing of immune checkpoint here. Obviously, at this point, we have multiple different trial readouts, and there are some options that patients can have just neoadjuvant without any adjuvant. Still, we have to figure out how to de-escalate post-surgery immunotherapy interventions. And I think there's a lot of work that needs to be done, and you're certainly involved in some of those exciting clinical trials. What do you do right now in your current clinical practice when you have patients who have a complete pathologic response to neoadjuvant immunotherapy? What is the discussion you have with your patients at that point? Do they need more immunotherapy, or are you ready to de-escalate?  Dr. Sandip Patel: I think MRD-based technologies, cell-free DNA technologies will hopefully help us guide this. Right now, we are flying blind along two axes. One is we don't actually know the contribution of the post-operative component for patients who get preoperative chemo-IO. And so this is actually going to be an ongoing discussion. And for a patient with a pCR, we know the outcomes are really quite good based on CheckMate816, which is a pure neoadjuvant or front-end only approach. Where I actually struggle is where patients who maybe have 50% tumor killing. If a patient has only 10% tumor killing ... the analogy I think in clinic is a traffic light, so the green light if you got a pCR, a yellow light if you have that anywhere from 20%-70% residual viable tumor, and then anything greater than that, you didn't get that much with chemo-IO and you're wondering if getting more chemo-IO, what would that actually do? It's a bit of a red light. And I'm curious, we don't have any data, but my guess would be the benefit of the post-op IO is because patients are in that kind of yellow light zone. So maybe a couple more cycles, we'll get them an even more durable response. But I am curious if we're going to start relying more on MRD-based technologies to define treatment duration. But I think it's a very complicated problem. I think folks want to balance toxicity, both medical and financial, with delivering a curative-intent therapy. And I am curious if this maybe, as we're looking at some of the data, some of the reasons around preferring a perioperative approach where you scale it back, as opposed to a neoadjuvant-only approach where there's not a clean way to add on therapy, if you think that makes sense. But it's probably the most complicated discussions we have in clinic and the discussion around a non-pCR. And frankly, even the tumor board discussions around localized non-small cell lung cancer have gone very complex, for the benefit of our patients, though we just don't have clean data to say this is the right path.   Dr. Vamsi Velcheti: I think that the need for a really true multidisciplinary approach and discussing these patients in the tumor board has never been more significant. Large academic centers, we have the luxury of having all the expertise on hand. How do we scale this approach to the broader community is a big challenge, I think, especially in early-stage patients. Of course, not everyone can travel to Dr. Zervos or you for care at a large tertiary cancer centers. So, I think there needs to be a lot of effort in terms of trying to educate community surgeons, community oncologists on managing these patients. I think it's going to be a challenge. Dr. Michael Zervos: If I could just add one thing here, and I completely agree with everything that has been said. I think the challenge is knowing beforehand. Could you predict which patients are going to have a complete response? And for that matter, say, “Okay. Well, this one has a complete response. Do we necessarily need to operate on this patient?” And that's really the big question that I add. I personally have seen some complete response, but what I'm mostly seeing is major pathologic response, not necessarily CR, but we are seeing more and more CR, I do have to say. The question is how are you going to predict that? Is looking for minimal residual disease after treatment going to be the way to do that? If you guys could speak to that, I think that is just tremendously interesting.  Dr. Vamsi Velcheti: I think as Sandip said, MRD is looking very promising, but I just want to caution that it's not ready for primetime clinical decision making yet. I am really excited about the MRD approach of selecting patients for de-escalation or escalation and surgery or no surgery. I think this is probably not quite there yet in terms of surgery or no surgery decision. Especially for patients who have early-stage cancer, we talk about curative-intent treatment here and surgery is a curative treatment, and not going to surgery is going to be a heavy lift. And I don't think we're anywhere close to that. Yet, I'm glad that we are having those discussions, but I think it may be too hard at this point based on the available technologies to kind of predict CR. We're not there.  Dr. Michael Zervos: Can I ask you guys what your thought process is for evaluating the patient? So, when you're actually thinking about, “Hey, this patient actually had a good response. I'm going to ask the surgeons to come and take a look at this.” What imaging studies are you actually using? Are you just using strictly CT or are you looking for the PET? Should we also be thinking about restaging a lot of these patients? Because obviously, one of the things that I hate as a surgeon is getting into the operating room only to find out that I have multiple nodal stations that are positive. Which really, in my opinion, that's sort of a red flag. And for me, if I have that, I'm thinking more along the lines of not completing that surgery because I'm concerned about not being able to provide an R0 resection or even having surgical staple lines within proximity of cancer, which is not going to be good. It's going to be fraught with complications.  So, a lot of the things that we as surgeons struggle with have to do with this. Personally, I like to evaluate the patients with an IV intravenous CT scan to get a better idea of the nodal involvement, proximity to major blood vessels, and potentially even a PET scan. And though I think in this day and age, a lot of the patients will get the PET beforehand, not necessarily get it approved afterwards. So that's a challenge. And then the one thing I do have to say that I definitely have found helpful is, if there's any question, doing the restaging or the re-EBUS at that point to be particularly helpful.  Dr. Sandip Patel: Yeah, I would concur that having that pathologic nodal assessment is probably one of the most important things we can do for our patients. For a patient with multinodal positive disease, the honest truth is that at our tumor board, that patient is probably going to get definitive chemoradiation followed by their immunotherapy, or potentially soon, if they have an EGFR mutation, osimertinib. For those patients who are clean in the mediastinum and then potentially have nodal flare, oftentimes what our surgeons will do as the first stage of the operation, they'll actually have the EBUS repeated during that same anesthesia session and then go straight into surgery. And so far the vast majority of those patients have proceeded to go to surgery because all we found are immune cells in those lymph nodes.  So, I think it's a great point that it's really the pathologic staging that's driving this and having a close relationship with our pathologists is key. But I think one point that I think we all could agree on is the way that we're going to find more of these patients to help and cure with these therapies is through improved utilization of low-dose CT screening in the appropriate population in primary care. And so, getting buy-in from our primary care doctors so that they can do the appropriate low-dose CT screening along with smoking cessation, and find these patients so that we can offer them these therapies, I think is something that we really, as a community, need to advocate on. Because a lot of what we do with next-generation therapies, at least on the medical oncology side, is kind of preaching to the choir. But getting the buy-in so we can find more of these cases at stage 1, 2 or 3, as opposed to stage 4, I think, is one of the ways we can really make a positive impact for patients. Dr. Vamsi Velcheti: I just want to go back to Mike's point about the nodal, especially for those with nodal multistation disease. In my opinion, those anatomic unresectability is a moving target, especially with evolving, improving systemic therapy options. The utilization for chemo radiation has actually gone down. I think that's a different clinical subgroup that we need to kind of think differently in terms of how we do the next iteration or generation of clinical trials, are they really benefiting from chemo-IO induction? And maybe we can get a subset of those patients in surgery. I personally think surgery is probably a more optimal, higher yield to potentially cure these patients versus chemo radiation. But I think how we identify those patients is a big challenge. And maybe we should do a sequential approach induction chemo-IO with the intent to kind of restage them for surgery. And if they don't, they go to chemo consolidation radiation, I guess. So, I think we need to rethink our approach to those anatomically unresectable stage 3s. But I think it's fascinating that we're having these discussions. You know, we've come to accept chemo radiation as a gold standard, but now we're kind of challenging those assumptions, and I think that means we're really doing well in terms of systemic therapy options for our patients to drive increased cures for these patients. Dr. Michael Zervos: I think from my perspective as a surgeon, if I'm looking at a CT scan and trying to evaluate whether a patient is resectable or not, one of the things that I'm looking for is the extent of the tumor, proximity to mediastinal invasion, lymph nodes size. But if that particular patient is resectable upfront, then usually, that patient that receives induction chemo checkpoint inhibition is going to be resectable afterwards. The ones that are harder are the ones that are borderline resectable upfront or not resectable. And then you're trying to figure out on the back end whether you can actually do the surgery.  Fortunately, we're not really taking many patients to the operating room under those circumstances to find that they're not resectable. Having said that, I did have one of those cases recently where I got in there and there were multiple lymph node stations that were positive. And I have to say that the CT really underestimated the extent of disease that I saw in the operating room. So, there are some challenges surrounding all of these things. Dr. Sandip Patel: Absolutely. And I think for those patients, if upfront identification by EBUS showed multi nodal involvement, we've had excellent outcomes by working with radiation oncologists using modern radiotherapy techniques, with concurrent chemo radiation, followed by their immunotherapy, more targeted therapy, at least it looks like soon. I think finding the right path for the patient is so key, and I think getting that mediastinal pathologic assessment, as opposed to just guessing based on what the PET CT looks like, is so important. If you look at some of the series, 8% to 10% of patients will get a false-positive PET on their mediastinal lymph nodes due to coccidioidomycosis or sarcoidosis or various other things. And the flip side is there's a false-negative rate as well. I think Mike summarized that as well, so I think imaging is helpful, but for me, imaging is really just pointing the target at where we need to get pathologic sampling, most commonly by EBUS. And getting our interventional pulmonary colleagues to help us do that, I think is so important because we have really nice therapeutic options, whether it's curative-intent surgery, curative-intent chemo radiation, where we as medical oncologists can really contribute to that curative-intent local therapy, in my opinion.  Dr. Vamsi Velcheti: Thank you so much Sandip and Mike, it's been an amazing and insightful discussion, with a really dynamic interplay between systemic therapy and surgical innovations.

Drs. Shaalan Beg and Aparna Parikh discuss the role of ctDNA as a powerful prognostic biomarker for GI cancers, along with its impact on risk stratification and the detection of recurrence. They highlight key studies in ctDNA that were featured at the 2024 ASCO GI Cancers Symposium, including COBRA, GALAXY, and BESPOKE in CRC, as well as the promise of ctDNA testing in the preoperative detection of iCCA. TRANSCRIPT Dr. Shaalan Beg: Hello, and welcome to the ASCO Daily News Podcast. I am Dr. Shaalan Beg, your guest host for the ASCO Daily News Podcast today. I am an adjunct associate professor at UT Southwestern's Harold Simmons Comprehensive Cancer Center in Dallas. On today's episode, we will be discussing the emergence of circulating tumor DNA (ctDNA) technology in GI cancers. I am delighted to be joined by Dr. Aparna Parikh, an assistant professor of medicine at Harvard University and the director for colorectal medical oncology at the Massachusetts General Hospital Cancer Center, where she also serves as the medical director of the Young Adult Colorectal Cancer Center. Dr. Parikh will share her insights on key research on this hot topic in GI oncology that was featured at the recent ASCO Gastrointestinal Cancers Symposium.  Our full disclosures are available in the transcripts of this episode, and disclosures related to all episodes of the podcast are available at asco.org/DNpod.  Dr. Parikh, it's great to have you on the podcast today. Dr. Aparna Parikh: Thanks so much, Dr. Beg.  Dr. Shaalan Beg: In recent years, it has become evident that liquid biopsy and other emerging ctDNA technologies are changing how we treat GI cancers, and colorectal cancer (CRC) is in the forefront of this space. Before we dive into key studies, can you briefly highlight for our listeners how ctDNA is advancing the field and how it can influence the care that we deliver to our patients in the future? Dr. Aparna Parikh: Absolutely, ctDNA is certainly a hot topic. What we have learned over the years is that ctDNA has emerged across many solid tumor types as one of the most powerful, if not the most powerful, prognostic biomarker we have to date. ctDNA has improved risk stratification. We have learned a lot about the role in what is called minimal or molecular residual disease in patients with early-stage disease, and ctDNA being a biomarker of recurrence for those patients, with ctDNA, we have a better understanding of tumoral heterogeneity, both spatially and temporally, getting a better glimpse of what is happening in a given patient with multiple metastases, as well as genomic evolution of tumors over time. So certainly many, many roles and areas where ctDNA is emerging. Dr. Shaalan Beg: This was a hot topic at the 2024 ASCO GI Cancers Symposium, and we're going to take a deep dive into some of the abstracts that were presented. Let's start with the COBRA study, which is the NRG-GI005. That was Abstract 5 at the ASCO GI Cancers Symposium, and the GALAXY study, which was Abstract 6 at the symposium. So, the COBRA study reported results of ctDNA as a predictive biomarker in adjuvant chemotherapy for people with colon cancer. At a high level, it was a negative study, but there are some important lessons for us to learn. Similarly, in the GALAXY study, investigators from Japan presented an updated analysis on the correlation of ctDNA dynamics with outcomes in colorectal cancer with minimal residual disease. How do you synthesize all this information and help the listeners understand our current state for ctDNA applications in colorectal cancer? Dr. Aparna Parikh: Yeah. Let's take the COBRA study first. Let's talk a little bit about the design of COBRA. COBRA was intended to look at patients that were resected, stage 2 colorectal cancer patients, or colon cancer patients who were 2A. These are patients where the treating physician would, at the outset, decide that there was no adjuvant chemotherapy indicated. These are patients where active surveillance would be entirely appropriate as the standard of care. Patients were randomized to arm 1, which was active surveillance, or randomized to arm 2, which was assay-directed therapy. If there were ctDNA positive in arm 2, then they were given chemotherapy, FOLFOX or CAPOX. And if they were “ctDNA not detected,” then they would also go on to active surveillance.   And so, the plan was that nearly 1,500 patients are to be recruited, and at the time of this data cut, they had around 630-some patients. The primary objective was to look at the clearance rates of ctDNA between the ctDNA-positive cohorts, remember, the chemotherapy and the active surveillance cohorts at 6 months. They had around a 5% detection rate of ctDNA patients. Ultimately, that was around 16 patients. The reason that the study shut down was that what they found was that in the surveillance arm, the arm that was not getting any treatment, they had a ctDNA clearance of 43% versus 11% in the chemotherapy arm. They had an interim analysis to look at the clearance rate between the 2 arms, and what was surprising to the investigators and the community was what was happening in terms of clearance. Why do we have a 43% clearance rate in patients that were not getting anything? And so, because of that, the study was shut down as it did not meet its prespecified interim look at clearance in those 2 arms.   Many things came up in terms of learnings from COBRA. Number one was the characteristics of the assay. And so, you take an assay in a low-risk patient population that has a fixed specificity, and when your baseline prevalence of recurrence is so low, for example, in low-risk stage 2 patients, your composite predictive value is very susceptible to small changes in that specificity. And so, your PPV is going to be a lot lower in a low-risk patient population than a higher-risk patient population. The COBRA study used an older version of a tumor-uninformed assay, so it definitely called into question some characteristics of the assay. Is one-time-point clearance sufficient, and is that the right endpoint? We have seen now, including the GALAXY study that we'll talk about here, previously reported just spontaneous clearance happening in 5%, 10% of patients. The question with that spontaneous clearance is: Was it actually clearance, or was chemotherapy just perhaps in a low ctDNA shedding state? Are you just suppressing the ctDNA below the level of limited detection?  And then in this study, the clearance draw was actually done in the chemotherapy arm right before the last cycle of chemotherapy, again to that point of, are you just suppressing the ctDNA with chemotherapy? There is also stochastic sampling error that can happen in patients with very low residual tumor volume. So, I think this is a disappointing study in the sense that it is still a really important question. There are still 2A patients that recur, but maybe [this was] not the right test, or maybe single-time-point testing wasn't enough. And so, lots of lessons to be learned from this study in terms of test and design, but hopefully more to come. I think certainly stage 2 patients remain an area where I think, hopefully, ctDNA still plays a factor for those patients.  Dr. Shaalan Beg: And how was the patient population for the GALAXY study? That was Abstract 6, compared to the COBRA study. Could you summarize those findings for us?  Dr. Aparna Parikh: Yeah, so GALAXY was part of a large study in Japan that includes an observational cohort plus therapeutic cohorts as well. And so, GALAXY was just further reporting of the observational cohort. So unlike COBRA, which is a low-risk, stage 2 study that was actually asking that interventional question: Can you use it to guide therapy? The GALAXY and the updated GALAXY just continues to show more clinical validity data rather than clinical utility data. And it was nearly 3,000 patients, pan stages. Again, the lion's share were stage 2 and 3 patients, but there were also stage 1 and stage 4 patients as well. And what they showed was that ctDNA is undoubtedly prognostic. They showed very consistent Kaplan-Meier curves, which we've seen time and time again, where if you're ctDNA-positive, you don't do as well.  What they showed was, not surprisingly, with longer-term follow-up – this is 24-month follow up, so longer-term follow up than was published in their paper last year – was that when you test at one time point, so landmark testing, the sensitivity of detecting recurrence was around 48%, and that fell from the publication last year which was around 58%, 59%, which is not surprising as you follow more people. I think single time point testing soon after surgery may miss those late recurrences, but it's still prognostic and showed a specificity of around 94%.   They also continued to show that if you continued to test with serial testing, your sensitivity improves, but what was really interesting and new, what they presented this time, was a clearance analysis. And showing, again, comparable to COBRA, in many ways, in the sense that clearance can be a little bit finicky, especially at one time point, is what they showed is that patients who had sustained clearance, and these are patients that had at least two time points with their ctDNA remained to be negative, they did very well. But if you had transient clearance, and again, the definition was a little bit broad, at least having one negative and then one positive, those patients ultimately, at 24 months, the curves came together with the no clearance curve. So initially, they did better than the people that didn't have any clearance. But if you transiently cleared at two years, the curves came back together.   And what was interesting is that in those patients that sort of transiently clear by 9 to 12 months, 80% of those are actually having a rapid return of ctDNA. And so this begs the question of was chemotherapy just suppressing that ctDNA or maybe if you have a better test you could have actually improved it.  These were some of the updated, interesting learnings from GALAXY, which remains incredibly prognostic. And then the concept of clearance, which I think we have to look into a little bit more as a field, and understanding that maybe just one time point clearance isn't sufficient.  Dr. Shaalan Beg: Yeah, and one of the most important applications for ctDNA can be its ability to inform adjuvant chemotherapy. Its ability to not only identify more people who may benefit from chemotherapy, but maybe even identify people who don't need chemotherapy. And along those lines, Abstract 9, the BESPOKE study, looked to understand the role of ctDNA-based detection of molecular residual disease to inform adjuvant therapy for stage 2 and 3 colorectal cancer. And they presented interim data at the GI ASCO this year. What were your takeaways from this study? Dr. Aparna Parikh: Exactly. Beyond the prognostic implications, I think what was really interesting was that there was the initial data looking at the benefit of adjuvant chemotherapy. So, what they did was they said, “Okay. We're going to take the MRD-positive patients and look at the benefit of adjuvant chemotherapy and then the benefit of adjuvant chemotherapy in the MRD-negative patients.” And again, remember, this is a prospective observational study, so it's not looking at negative and positive to guide therapy, but it's just looking prospectively and observationally at how those patients are doing. But what they showed again is that indeed, in the adjuvant chemotherapy group, the benefit of adjuvant chemotherapy again with the follow-up to date on the study was different in the MRD-positive patients.  First of all, I guess taking a step back, the DFS in the ctDNA-negative patients at 2 years was very good. So negative patients had over 98% 2-year DFS in both the adjuvant chemotherapy and observational group. And there was no real difference between adjuvant or not. But in the positive patients, not surprisingly, the DFS was worse. But what was reassuring to see is that you can make an impact with adjuvant chemotherapy in the positive patients. And the difference in DFS between the positive and negative patients, with adjuvant or not, was 42% versus 12.5%, in the observational patients. So, it is benefitting the patients who are positive so it does give us more data that, again, at least in the positive patients, you may be able to reverse the recurrences there with adjuvant chemotherapy. And maybe if you're negative, eventually, we'll get to a point of de-escalation of care. Again, keeping in mind the kinds of sensitivity limitations as well.  Dr. Shaalan Beg: Wonderful. And one of the other malignancies in the GI space where precision therapies and molecular biomarkers are making a huge difference are intrahepatic cholangiocarcinoma. Genomic profiling using ctDNA is increasingly being used in this population to inform precision oncology approaches and determine mechanisms of resistance to targeted therapies as well. In Abstract 528, investigators looked at the role of preoperative ctDNA testing for resectable intrahepatic cholangiocarcinoma. What are your thoughts on that study?  Dr. Aparna Parikh: Yeah, it's such an important area, as you mentioned, in the metastatic space – FGFR, IDH1, all these alterations that are emerging in intrahepatic cholangios. This was a very small study, it was preoperative, and so the tumor was intact, and around 14 patients. They used a tumor-informed approach just for detection and quantification of ctDNA. So this was not a study that was looking at a next-generation sequencing approach where you're going to actually be able to detect the alterations, but it's actually looking for the detection and quantification of ctDNA rather than genomic characterizations. And patients had about a month or so where they had their baseline blood detected. And I think what was reassuring to say was that ctDNA was actually detected in all the patients with the primary tumor intact, except for one patient who was a very low-risk stage 1A patient. There was some correlation, against a small number of patients, between the concentration of ctDNA in patients that had the lower stage and then the higher stage groups. Small numbers were actually hard to characterize and correlate with recurrence or mortality, but at least, some correlation with pathologic tumor size, they were able to because it was a bespoke panel and you're sampling the tissue and then looking in the blood, IDH1 and 2 were mutations that were tracked based on the genomic profiling and a couple of the patients were able to have their IDH mutations tracked.  So it gives us a sense, a little bit, that ctDNA, we know has a lot of variable shedding across disease states and tumor locations, but gives us some promise that it is reliably detected with the tumor-informed approach, at least preoperatively in cholangios. So may again open some more opportunities for MRD testing in cholangiocarcinoma as well.  Dr. Shaalan Beg: Thank you.

The scientific advances and innovative, multidisciplinary approaches that were featured throughout the meeting were really inspiring and reflect the incredible strides we're making in GI cancer research. Dr. Rachna Shroff: Thank you so much for having me back. I am delighted to be here.  Dr. Shaalan Beg: Dr. Shroff, the theme of this year's symposium was "Taking Personalized Care to the Next Level." I'd love to hear your reflections on the sessions that you found most exciting and really resonated with the attendees.  Dr. Rachna Shroff: Yes, thank you. We were really excited about this theme because we really felt that “Taking Personalized Care to the Next Level” translated to thinking through personalized approaches to patient care, not just in the traditional ways that we think of with precision oncology and genomics driving our care, but also how we can think through multidisciplinary approaches and an individualized care plan. Thinking through how artificial intelligence and novel clinical trial designs can and should be implemented to meet the needs of our individual patients. And so we really highlighted that in what was a somewhat new reboot of a session called “Intersections,” which were every day and were really more cross-tumor; they were tumor agnostic but were thematic focused. As I mentioned, those themes were really based on feedback that we had from prior attendees, as well as from the program committee's feeling on what are really the questions that we are dealing with and that are burning in the clinic today and that includes the emerging role of artificial intelligence and machine learning and how we integrate that into our clinical care, approaches to oligometastatic disease, and it's not really just something that we think of in colorectal cancer but haven't fully used that paradigm to really apply it to other GI malignancies. And then the art and science of clinical trial design where, again, traditional randomized phase 3 trials might not be the best and most innovative and most expedient way of bringing novel therapeutics to our patients. And so, I thought that all of those sessions were really highlighting different important topics that we deal with day to day. Additionally, we had a really fantastic keynote lecture from Dr. Kimmie Ng of the Dana-Farber Cancer Institute. She is a world-renowned expert in the early-onset colorectal cancer space, and the timing of her keynote was perfect with the new cancer statistics that came out literally days before GI ASCO that demonstrated this just dramatic rise in early onset GI malignancies as a whole, not just colorectal. And she spoke really in a comprehensive manner not just on clinical approaches, screening approaches, and how to find these patients at an earlier stage, but also kind of gave us a call to action, if you will, in terms of public health initiatives, as well as like I said, clinical care and really thinking outside of the box for how to reach these patients.  And then, of course, we always have what I think is one of my favorite aspects of the meeting, which are the networking opportunities that include the Trainee and Early Career Networking Luncheon, the Women's Networking Reception, and the Meet the Experts Luncheon where, especially as junior career investigators, you have an opportunity to meet what we think of as the “big names” in GI cancer. Dr. Shaalan Beg: Absolutely, I remember my first couple of GI ASCO meetings and those were probably the most memorable sessions that I attended as junior faculty as well.   So let's take a deeper dive into some key abstracts from the meeting. I'd like to begin with Abstract 245. This is the SKYSCRAPER-08 study. It's first-line tiragolumab and atezolizumab with chemotherapy in an Asian patient population with esophageal squamous cell carcinoma. What are your key takeaways from this study?  Dr. Rachna Shroff: Yeah. This was an exciting study in my opinion in the sense that thinking through how we can build on immunotherapy backbones is obviously a pressing question across the GI cancer space. So this was a phase 3 randomized, double-blinded, placebo-controlled trial that looked specifically at patients with esophageal squamous cell carcinomas. And the study was enrolled fully with an Asian population. It looked at taking the traditional chemotherapy backbone and adding to it an anti-PD-L1 with atezolizumab and an anti-TIGIT with tiragolumab. Again, that proof of principle of using anti-TIGIT and PD-L1 has been looked at across a lot of different GI cancer spaces and we know that the esophageal squamous cell cancers tend to be very immunotherapy responsive. So this was a really important question.  This involved a number of patients, a little over 460 patients, who were randomized one-to-one to receive the tiragolumab with atezolizumab with the standard paclitaxel and cisplatin, that's used for esophageal squamous versus chemotherapy alone with placebo. And the primary endpoint was independent review of progression-free survival, and overall survival. And so, out of the 461 patients randomized, there was at the primary analysis, a median improvement in progression free survival, from 5.4 months in the control arm to 6.2 months with a tira-paclitaxel plus chemo arm with a hazard ratio of 0.56, highly statistically significant. Similarly the median overall survival was also improved from 11.1 months to 15.7 months again with a hazard ratio of 0.7 and some of the other key efficacy endpoints were also improved with the addition of the anti-TIGIT PD-L1 approach. And importantly, there was not really safety signals that jumped out at us.  And so, to me, what this means is that, in our patients with esophageal squamous cell carcinoma, we really should be thinking about chemotherapy with immunotherapy as a backbone and how we can build on it. And, you know, I would imagine that it's hard to argue with both the PFS and OS endpoint that adding anti-TIGIT won't necessarily be kind of the new approach to these patients. And importantly, I'll point out that it seems to be a benefit across the subgroups, including PD-1 status, which is always our big question here. I think the only thing to keep in mind is this was an all-Asian population and whether or not that kind of immune profile of the immune responsiveness is different in those patients, but regardless, a positive phase 3 trial. Dr. Shaalan Beg: It's really exciting to see immune checkpoint inhibitors or immunotherapy beyond PD-1 targeted, CTLA-4 targeted treatments making their way into GI Cancers.  Dr. Rachna Shroff: Absolutely. Dr. Shaalan Beg: Sticking with the immunotherapy theme, let's focus on hepatocellular carcinoma. So LBA432, the EMERALD-1 study of transarterial chemoembolization combined with durva with or without bevacizumab looked at people with unresectable hepatocellular carcinoma eligible for embolization. So really a highly anticipated study, I'm wondering what your thoughts are and whether it'll be practice-changing for this field.  Dr. Rachna Shroff: I was excited to see the press release when it showed that the study was positive, and I think it's because now that we're using immunotherapy in the advanced HCC space, our obvious question is, can we integrate it into multimodality approaches? There are a lot of smaller studies looking at neoadjuvant IO approaches, and in this intermediate stage, unresectable hepatocellular carcinoma patients. We wanted to know if there was a utility to liver directed therapy with immunotherapy.  So, this was a large study. It was a global study looking at unresectable HCC with preserved Child-Pugh function. But it was Child-Pugh A and up to B7, importantly. And there were 616 patients randomized in a 1:1:1 fashion, with the control arm being just TACE alone. But then, there was also an opportunity for durvalumab with TACE, as well as durvalumab plus bevacizumab with TACE. The patients would receive durvalumab during their TACE treatments and could receive up to four TACE treatments and then subsequently were either continued on durvalumab alone, durvalumab plus bevacizumab, or the placebo. The primary endpoint was progression-free survival, powered specifically to look at TACE versus durvalumab plus TACE. In this study, the primary endpoint was met with a significant improvement in PFS. Median PFS was 15 months versus 8.2 months, with a hazard ratio of 0.77. Most prespecified subgroups demonstrated this benefit.  Importantly, there was a secondary endpoint looking at durvalumab plus TACE versus TACE alone, and that actually did not show a statistically significant improvement in median PFS from 8.2 months in the control arm to 10.0 months. The overall response rates were slightly higher with the durvalumab plus bevacizumab approach at 43.6%. And importantly in these patients, who oftentimes have a higher burden of disease in the liver, median time to progression is a really important and clinically meaningful endpoint. That was 22 months with the durvalumab plus bevacizumab and TACE versus 10 months for TACE alone. I would just point out that the overall concern we always have with bevacizumab is the increased risk of bleeding and the treatment-related adverse event profile. Overall, there were no safety signals that emerged from this, with nothing that really, especially in that bleeding risk category, jumped out at us. Of course, we haven't seen the overall survival data yet because we have not seen enough follow-up to really see that number.  I do think that this is potentially practice-changing, and I think it just demonstrates that there's probably some synergy between anti-VEGF with anti-PD-1, and then the liver-directed treatments. The obvious question for us in the United States is that the vast majority of people are moving away from TACE and towards more radioembolization and what can we extrapolate from this? Does this really tell us much if people are using more of a Y90-based approach? I think those are a lot of the burning questions that most of us have.  Dr. Shaalan Beg: Yeah, and it's a very interesting direction that the HCC space is taking because we heard in previous meetings, the role of PD-1 inhibition as adjuvant therapy after resection. Now, we have data for local-regionally advanced disease over local-regional treatments. And of course, you already mentioned the data for more advanced disease. So it sounds like immunotherapy may be impacting the management of anyone diagnosed with hepatocellular carcinoma.  Let's talk about the MONET trial, Abstract 249, which compared thoracoscopic esophagectomy and open esophagectomy for thoracic esophageal cancer. Do you think this is a study which may influence the treatment of patients with thoracic esophageal cancer? Dr. Rachna Shroff: So, this was, again, I think, a really important question. It was a randomized, controlled phase 3 trial comparing a more minimally invasive approach with TE — thoracoscopic esophagectomy — versus an open approach. This had patients with clinical stage 1-3, excluding T4 thoracic esophageal squamous cell carcinomas. They were randomized 1:1 to the open versus the TE approach, with a primary endpoint of overall survival and an important secondary endpoint of relapse-free survival. 300 patients were randomized, and at the second planned interim analysis, the median follow-up was a little over two and a half years. The 3-year overall survival was 82% in the TE group versus 70.9% in the open group. The DSMC of this trial actually recommended early termination based on the non-inferiority, which is what they were specifically looking at. There was a very statistically significant one-sided p-value for non-inferiority.  Importantly, the 3-year recurrence-free survival was also markedly better in the TE group versus the open group, with no real notable differences in R0 resection, or a large percentage of patients who needed to be converted from a TE to an open approach, and really not any significant difference in overall postoperative morbidity. I think this just supports the concept that minimally invasive approaches for our patients with GI malignancies can and should be considered. Again, esophageal squamous because they tend to be seen a lot more in Asia, this study was conducted in Japan, but I think that being said, a lot of our surgeons in Europe and in the U.S. are also very amenable to minimally invasive approaches. And I think this just supports the fact that an open approach is not necessary. So, I would think again, that this is something that is implementable and I think will affect the field.  Dr. Shaalan Beg: Moving on to metastatic cholangiocarcinoma, there have been many FGFR inhibitors that have shown activity and promise and are approved for the management of cholangiocarcinoma with FGFR alteration. But at this ASCO GI, we heard the results of the safety and efficacy of an FGFR1, 2, and 3 inhibitor, tinengotinib, as monotherapy for advanced metastatic cholangiocarcinoma (Abstract 434). How do you see this fitting into the broad picture? Dr. Rachna Shroff: Yeah, so this was highly anticipated data, primarily because at this point, the FGFR space in cholangiocarcinoma is quite crowded. And so a lot of us were getting sick of the "me-too" drugs. What is really unique about tinengotinib is that, not only is it a selective multikinase inhibitor, but it also, in preclinical models as well as in early phase one trials, demonstrated potent inhibition of patients with FGFR2 fusions and rearrangements who had acquired resistance mutations. So, as we better understand the first generation of FGFR inhibitors and note the resistance mechanisms, these drugs are now being developed to try to circumvent or overcome those.  This study looked at 4 different cohorts: 1 cohort with FGFR2 fusion patients who had primary progression who never responded to FGFR inhibitors, a second cohort with FGFR2 fusion patients who had progression after primary response, so those with acquired resistance, and then there was non-fusion FGFR alterations because we do know that a number of cholangiocarcinoma patients have other FGFR alterations that are not fusions, and then those with FGFR wild-type. The primary endpoint was objective response rate, with a total of 48 patients enrolled across the four cohorts. And so the 40 patients who were evaluable in the group that had primary resistance, which was the first cohort, there was a response rate was 9.1% and that was partial response, and 31% had tumor reduction with tinengotinib. And similarly in those with acquired resistance, 37.5%, 3 out of 8 patients had a partial response and tumor reductions were noted with an overall disease control rate between those patients with FGFR2 fusions of 94.7%, between those with primary and secondary resistance.  In the patients who had FGFR alterations, there was 3 out of 9 patients with a partial response and again, tumor reductions were notable across the board and the disease control rate was 88.9%. The FGFR wild-type group, not surprisingly, did not see any partial responses, but interestingly, 75% of these patients had at least disease control, and the median progression-free survival was 5.26 months, again, kind of most notably impressive in the 2 cohorts that included FGFR2 fusions. The toxicity profiles are what we come to expect for FGFR inhibitors and we've gotten better at managing those and mitigating some of those so there was really nothing to jump out there. So there is now an ongoing randomized phase III trial specifically looking at tinengotinib versus physician's choice in patients with FGFR2-altered cholangiocarcinoma after having received prior FGFR inhibitors. So that's where I think it's in is for those of us who know that there are multiple drugs in the space, our big question is can we sequence through that? Can we offer multiple FGFR inhibitors in these patients? And I think we are all eagerly anticipating this data as well as the subsequent data to really justify the use of these novel second generation FGFR inhibitors.  Dr. Shaalan Beg: It's been fantastic to see the evolution of these compounds in precision medicine, or precision oncology at its finest, in terms of understanding mechanisms of resistance and treating refractory disease.   Let's focus on colorectal cancer. I'll tell you, there has been a lot of discussion, Dr. Shroff, on social media, on insurance companies sometimes rejecting one biologic or the other based on tumor sidedness. We have talked about tumor sidedness predicting response on this podcast based on data from previous studies. But this year in GI ASCO, Abstract 207 explored the role of tumor genomics and tumor sidedness and they said that it's tumor genomics, that tumor genomics better explains the differences on outcomes, and it explains it better than sidedness. What does this mean to the field? Because a lot of professional organizations have guidelines that are asking people to now incorporate sidedness. So how does that change based on these results? Dr. Rachna Shroff: I really commend these authors on leveraging real-world data, and I think we're getting better and better at recognizing that real world data actually informs our clinical decision making, possibly better than sometimes some of these studies that lead to the guidelines and algorithms that we develop. So this is a perfect example of a little bit cart before horse in trying to understand the way that sidedness and genomics may interplay.   So this was a study that basically leveraged both the Foundation Medicine and Flatiron Health clinical genomic database and looked at patients with microsatellite stable metastatic colorectal cancer. There were a total of 3,845 patients included in a kind of two-thirds one-third split between left sided and right-sided colorectal cancer. And they found the typical genomic alterations that historically have been thought of more with left-sided colorectal cancer like APC and then more of the RAS BRAF alterations in the right-sided patients. But I think what they really thought and what I think was remarkable is they really looked at the patients and how they received chemotherapy with anti-EGFR or bevacizumab therapies, and they did a multivariate analysis to really see what is driving outcomes. And like you mentioned, what they found was patients in the RAS pathway, those classified as having alterations in the RAS pathway, had less favorable outcomes, while those with APC altered group had more favorable outcomes. And that was regardless of treatment received and sidedness.  And so when they did an analysis of what was called a “likelihood ratio test,” they found that when genomics was added to the sidedness evaluation, there was an improvement in outcome prediction, but not when sidedness was added to genomics. Like you said, it kind of demonstrates, at least in this mining of real-world data from Flatiron that tumor genomics is probably a better driver and a more important driver in determining outcomes than sidedness.  I totally agree with you. I would push for us to really kind of bring a little bit of noise to this and to make insurance companies and other companies that are looking at this to think through this a little bit more and make sure that we're putting all of the data together in a comprehensive passion before making the treatment plans and determinations. Dr. Shaalan Beg: The last abstract I'd like to ask you about is Abstract 117, the NEST-1 trial. This study looked at neoadjuvant botensilimab and balstilimab for resectable mismatch repair proficient and deficient colorectal cancer, both MSS and MSI. What are your key takeaways from this study?  Dr. Rachna Shroff: This is another study that is demonstrating that there may potentially be a role for immunotherapy in microsatellite stable patients. I will make the caveat that this was a single-arm study that really was looking at feasibility safety, with efficacy as a secondary endpoint. The combination of bot-bal in the neoadjuvant space for colorectal cancer patients, they received one dose of boten and two fixed doses of bal two weeks apart and then were taken to surgery. They limited the number of patients and out of the 12 patients that were enrolled, they limited the number of mismatch repair deficient patients. So to your point, they allowed both, but they wanted to make sure it was not just MSI-high patients. What they basically found is that it was safe and did not delay surgery or increase risks of adverse events. But importantly, there was significant regression of tumor noted. And some interesting spatial biology analyses demonstrated potentially novel mechanisms of action, especially in the MSS population, and that ctDNA reductions correlated with pathologic response. There were a lot of different things that they were looking at, basically suggesting that bot-bal is safe and can be used in both mismatch repair–deficient and proficient patients with colorectal cancer. And now importantly, they've added some additional cohorts and expanding the study. As I mentioned, this is right now just 12 patients, but does definitely have a provocative result.  Dr. Shaalan Beg: Thanks so much, Dr. Shroff.  Finally, the role of cell-free DNA (cfDNA) in GI cancers has been an exciting and important development in our field. There's tremendous data that emerged at the GI meeting, and we have decided to do a separate ASCO Daily News Podcast dedicated to ctDNA. So listeners, please look out for our coverage of key studies on ctDNA in GI cancers very soon here on the ASCO Daily News Podcast.  Many thanks, Dr. Shroff, for sharing your insights with us today and for your great work in building a robust GI meeting this year.

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.
