Host: Charles Turck, PharmD, BCPS, BCCCP Guest: Andrea Necchi, MD Presented at the 2025 ESMO Congress, the IMvigor011 phase 3 trial evaluated a ctDNA-guided strategy for administering adjuvant atezolizumab in patients with muscle-invasive bladder cancer (MIBC) following radical cystectomy. Patients with high-risk pathological features were monitored using a personalized, tumor-informed ctDNA assay; those testing positive for ctDNA were randomized to receive atezolizumab or placebo, while ctDNA-negative patients continued surveillance without treatment. The trial demonstrated significant improvements in both disease-free and overall survival in the atezolizumab group along with favorable outcomes among ctDNA-negative patients, suggesting many may safely avoid overtreatment. Joining Dr. Charles Turck to unpack the study results and how they highlight ctDNA's role in guiding personalized therapy is Dr. Andrea Necchi. Not only is he an investigator on this research, but he's also an Associate Professor of Oncology at Vita-Salute San Raffaele University and the Director of Genitourinary Medical Oncology at IRCCS San Raffaele Hospital and Scientific Institute in Milan, Italy.

Join us as we bring the year to a close by chatting with Dr Rob Lentz from Natera about how circulating tumour DNA testing can inform better treatment decisions in the clinic. We hear about the power of ctDNA alongside reference tumour informed testing and the latest data supporting it's use in GI as well as many other cancers.

In today's episode, we had the pleasure of speaking with Jason Mouabbi, MD, about the role of circulating tumor DNA (ctDNA) testing in early-stage breast cancer management. Dr Mouabbi is an assistant professor in the Department of Breast Medical Oncology in the Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center in Houston. In our exclusive interview, Dr Mouabbi highlighted the ways that ctDNA has evolved from a research tool to a potential clinical decision-making aid in breast cancer, data suggesting that ctDNA negativity after neoadjuvant therapy can be more predictive of long-term outcomes than pathologic complete response, and the importance of offering ctDNA testing to patients and discussing the benefits of this emerging approach.

This week, we look at ctDNA-guided immunotherapy for bladder cancer, cardiovascular outcomes with tirzepatide, and evidence that one HPV vaccine dose may be enough. We explore high-dose rifampin for tuberculous meningitis, review measles amid rising outbreaks, and follow a challenging case of gastrointestinal bleeding. Essays examine how clinicians navigate post-Dobbs care, tobacco harm among people with mental illness, congenital syphilis, and sustaining medical research.

JCO PO author Dr. Shilpa Gupta at Cleveland Clinic Children's Hospital shares insights into her article, "Fibroblast Growth Factor Receptor 3 (FGFR3) Alteration Status and Outcomes on Immune Checkpoint Inhibitors (ICPI) in Patients with Metastatic Urothelial Carcinoma". Host Dr. Rafeh Naqash and Dr. Gupta discuss how FGFR3 combined with TMB emerged as a biomarker that may be predictive for response to ICPI in mUC. 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 JCO PO articles. I'm your host, Dr. Rafeh Naqash, podcast editor for JCO Precision Oncology and Associate Professor at the OU Health Stephenson Cancer Center. Today I am excited to be joined by Dr. Shilpa Gupta, Director of Genitourinary Medical Oncology at the Cancer Institute and co-leader of the GU Oncology Program at the Cleveland Clinic, and also lead author of the JCO PO article titled "Fibroblast Growth Factor Receptor 3 Alteration Status and Outcomes on Immune Checkpoint Inhibitors in Patients With Metastatic Urothelial Carcinoma." At the time of this recording, our guest's disclosures will be linked in the transcript. Shilpa, welcome again to the podcast. Thank you for joining us today. Dr. Shilpa Gupta: Thank you, Rafeh. Honor to be here with you again. Dr. Rafeh Naqash: It is nice to connect with you again after two years, approximately. I think we were in our infancy of our JCO PO podcast when we had you first time, and it has been an interesting journey since then. Dr. Shilpa Gupta: Absolutely. Dr. Rafeh Naqash: Well, excited to talk to you about this article that you published. Wanted to first understand what is the genomic landscape of urothelial cancer in general, and why should we be interested in FGFR3 alterations specifically? Dr. Shilpa Gupta: Bladder cancer or urothelial cancer is a very heterogeneous cancer. And while we find there is a lot of mutations can be there, you know, like BRCA1, 2, in HER2, in FGFR, we never really understood what is driving the cancer. Like a lot of old studies with targeted therapies did not really work. For example, we think VEGF can be upregulated, but VEGF inhibitors have not really shown definite promise so far. Now, FGFR3 receptor is the only therapeutic target so far that has an FDA approved therapy for treating metastatic urothelial cancer patients, and erdafitinib was approved in 2019 for patients whose tumors overexpressed FGFR3 mutations, alterations, or fusions. And in the landscape of bladder cancer, it is important because in patients with non-muscle invasive bladder cancer, about 70 to 80% patients can have this FGFR3. But as patients become metastatic, the alterations are seen in, you know, only about 10% of patients. So the clinical trials that got the erdafitinib approved actually used archival tumor from local cancer. So when in the real world, we don't see a lot of patients if we are trying to do metastatic lesion biopsies. And why it is important to know this is because that is the only targeted therapy available for our patients right now. Dr. Rafeh Naqash: Thank you for giving us that overview. Now, on the clinical side, there is obviously some interesting data for FGFR3 on the mutation side and the fusion side. In your clinical practice, do you tend to approach these patients differently when you have a mutation versus when you have a fusion? Dr. Shilpa Gupta: We can use the treatment regardless of that. Dr. Rafeh Naqash: I recently remember I had a patient with lung cancer, squamous lung cancer, who also had a synchronous bladder mass. And the first thought from multiple colleagues was that this is metastatic lung. And interestingly, the liquid biopsy ended up showing an FGFR3-TACC fusion, which we generally don't see in squamous lung cancers. And then eventually, I was able to convince our GU colleagues, urologists, to get a biopsy. They did a transurethral resection of this tumor, ended up being primary urothelial and synchronous lung, which again, going back to the FGFR3 story, I saw in your paper there is a mention of FGFR3-TACC fusions. Anything interesting that you find with these fusions as far as biology or tumor behavior is concerned? Dr. Shilpa Gupta: We found in our paper of all the patients that were sequenced that 20% had the pathognomonic FGFR3 alteration, and the most common were the S249C, and the FGFR3-TACC3 fusion was in 45 patients. And basically I will say that we didn't want to generate too much as to fusion or the differences in that. The key aspect of this paper was that historically there were these anecdotal reports saying that patients who have FGFR alterations or mutations, they may not respond well to checkpoint inhibitors because they have the luminal subtype. And these were backed by some preclinical data and small anecdotal reports. But since then, we have seen that, and that's why a lot of people would say that if somebody's tumor has FGFR3, don't give them immunotherapy, give them erdafitinib first, right? So then we had this Phase 3 trial called the THOR trial, which actually showed that giving erdafitinib before pembrolizumab was not better. That debunked that myth, and we are actually reiterating that because in our work we found that patients who had FGFR3 alterations or fusions, and if they also have TMB-high, they actually respond very well to single agent immunotherapy. And that is, I think, very important because it tells us that we are not really seeing that so-called potential of resistance to immunotherapy in these patients. So to answer your question, yeah, we did see those differences, but I wouldn't say that any one marker is more prominent. Dr. Rafeh Naqash: The analogy is kind of similar to what we see in lung cancer with these mutations called STK11/KEAP1, which are also present in some other tumors. And one of the questions that I don't think has been answered is when you have in lung cancer, if you extrapolate this, where doublet or single agent immunotherapy doesn't do as well in tumors that are STK11 mutated. But then if you have a high TMB, question is does that TMB supersede or trump the actual mutation? Could that be one reason why you see the TMB-high but FGFR3 altered tumors in your dataset responding or having better outcomes to immunotherapy where potentially there is just more neoantigens and that results in a more durable or perhaps better response to checkpoint therapy? Dr. Shilpa Gupta: It could be. But you know, the patients who have FGFR alterations are not that many, right? So we have already seen that just patients with TMB-high respond very well to immunotherapy. Our last podcast was actually on that, regardless of PD-L1 that was a better predictor of response to immunotherapy. So I think it's not clear if this is adding more chances of response or not, because either way they would respond. But what we didn't see, which was good, that if they had FGFR3, it's not really downplaying the fact that they have TMB-high and that patients are not responding to immunotherapy. So we saw that regardless, and that was very reassuring. Dr. Rafeh Naqash: So if tomorrow in your clinic you had an individual with an FGFR3 alteration but TMB-high, I guess one could be comfortable just going ahead with immunotherapy, which is what the THOR trial as you mentioned. Dr. Shilpa Gupta: Yes, absolutely. And you know, when you look at the toxicity profiles of pembrolizumab and erdafitinib, really patients really struggle with using the FGFR3 inhibitors. And of course, if they have to use it, we have to, and we reserve it for patients. But it's not an easy drug to tolerate. Currently the landscape is such that, you know, frontline therapy has now evolved with an ADC and immunotherapy combinations. So really if patients progress and have FGFR3 alterations, we are using erdafitinib. But let's say if there were a situation where a patient has had chemotherapy, no immunotherapy, and they have FGFR3 upregulation and TMB-high, yes, I would be comfortable with using only pembrolizumab. And that really ties well together what we saw in the THOR trial as well. Dr. Rafeh Naqash: Going to the clinical applications, you mentioned a little bit of this in the manuscript, is combination therapies. You alluded to it a second back. Everything tends to get combined with checkpoint therapy these days, as you've seen with the frontline urothelial, pembrolizumab with an ADC. What is the landscape like as far as some of these FGFR alterations are concerned? Is it reasonable to combine some of those drugs with immune checkpoint therapy? And what are some of the toxicity patterns that you've potentially seen in your experience? Dr. Shilpa Gupta: So there was indeed a trial called the NORSE trial. It was a randomized trial but not a comparative cohort, where they looked at FGFR altered patients. And when they combined erdafitinib plus cetrelimab, that did numerically the response rates were much higher than those who got just erdafitinib. So yeah, the combination is definitely doable. There is no overlapping toxicities. But unfortunately that combination has not really moved forward to a Phase 3 trial because it's so challenging to enroll patients with such kind of rare mutations on large trials, especially to do registration trials. And since then the frontline therapy has evolved to enfortumab vedotin and pembrolizumab. I know there is an early phase trial looking at a next generation FGFR inhibitor. There is a triplet combination looking in Phase 1 setting with a next generation FGFR inhibitor with EV-pembro. However, it's not a randomized trial. So you know, I worry about such kinds of combinations where we don't have a path for registration. And in the four patients that have been treated, four or five patients in the early phase as a part of basket trial, the toxicities were a lot, you know, when you combine the EV-pembro and an FGFR3 inhibitor, we see more and more toxicity. So the big question is do we really need the "kitchen sink" approach when we have a very good doublet, or unless the bar is so high with the doublet, like what are we trying to add at the expense of patient toxicity and quality of life is the big question in my mind. Dr. Rafeh Naqash: Going back to your manuscript specifically, there could be a composite biomarker. You point out like FGFR in addition to FGFR TMB ends up being predictive prognostic there. So that could potentially be used as an approach to stratify patients as far as treatment, whether it's a single agent versus combination. Maybe the TMB-low/FGFR3 mutated require a combination, but the TMB-high/FGFR mutated don't require a combination, right? Dr. Shilpa Gupta: No, that's a great point, yeah. Dr. Rafeh Naqash: But again, very interesting, intriguing concepts that you've alluded to and described in this manuscript. Now, a quick take on how things have changed in the bladder cancer space in the last two years. We did a podcast with you regarding some biomarkers as you mentioned two years back. So I really would like to spend the next minute to two to understand how have things changed in the bladder cancer space? What are some of the exciting things that were not there two years back that are in practice now? And how do you anticipate the next two years to be like? Maybe we'll have another podcast with you in another two years when the space will have changed even more. Dr. Shilpa Gupta: Certainly a lot has happened in the two years, you know. EV-pembro became the universal frontline standard, right? We have really moved away from cisplatin eligibility in metastatic setting because anybody would benefit from EV-pembro regardless of whether they are candidates for cisplatin or not, which historically was relevant. And just two days ago, we saw that EV-pembro has now been approved for localized bladder cancer for patients who are cisplatin ineligible or refusing. So, you know, this very effective regimen moving into earlier setting, we now have to really think of good treatment options in the metastatic setting, right? So I think that's where a lot of these novel combinations may come up. And what else we've seen is in a tumor agnostic trial called the DESTINY-PanTumor trial, patients who had HER2 3+ on immunohistochemistry, we saw the drug approval for T-DXd, and I think that has kind of reinvigorated the interest in HER2 in bladder cancer, because in the past targeting HER2 really didn't work. And we still don't know if HER2 is a driver or not. And at ESMO this year, we saw an excellent study coming out of China with DV which is targeting HER2, and toripalimab, which is a Chinese checkpoint inhibitor, showing pretty much similar results to what we saw with EV-pembro. Now, you know, not to do cross-trial comparisons, but that was really an amazing, amazing study. It was in the presidential session. And I think the big question is: does that really tell us that HER2-low patients will not benefit? Because that included 1+, 2+, 3+. So that part we really don't know, and I think we want to study from the EV-302 how the HER2 positive patients did with EV and pembro. So that's an additional option, at least in China, and hopefully if it gets approved here, there is a trial going on with DV and pembro. And lastly, we've seen a very promising biomarker, like ctDNA, for the first time in bladder cancer in the adjuvant setting guiding treatment with adjuvant atezolizumab. So patients who were ctDNA positive derived overall survival and recurrence-free survival benefit. So that could help us select moving forward with more studies. We can spare unnecessary checkpoint inhibitors in patients who are not going to benefit. So I think there is a lot happening in our field, and this will help do more studies because we already have the next generation FGFR inhibitors which don't have the toxicities that erdafitinib comes with. And combining those with these novel ADCs and checkpoint inhibitors, you know, using maybe TMB as a biomarker, because we really need to move away from PD-L1 in bladder cancer. It's shown no utility whatsoever, but TMB has. Dr. Rafeh Naqash: Well, thank you so much, Shilpa, for that tour de force of how things have changed in bladder cancer. There used to be a time when lung and melanoma used to lead this space in terms of the number of approvals, the biomarker development. It looks like bladder cancer is shifting the trend at this stage. So definitely exciting to see all the new changes that are coming up. I'd like to spend another minute and a half on your career. You've obviously been a leader and example for many people in the GU space and beyond. Could you, for the sake of our early career especially, the trainees and other listeners, describe how you focused on things that you're currently leading as a leader, and how you shaped your career trajectory over the last 10 years? Dr. Shilpa Gupta: That's a really important question, Rafeh, and you and I have had these discussions before, you know, being an IMG on visas like you, and being in different places. I think I try to make the most of it, you know, instead of focusing on the setbacks or the negative things. Like tried to grab the opportunities that came along. When I was at Moffitt, got to get involved with the Phase 1 trial of pembrolizumab in different tumor types. And just keeping my options open, you know, getting into the bladder cancer at that time when I wanted to really do only prostate, but it was a good idea for me to keep my options open and got all these opportunities that I made use of. I think an important thing is to, like you said, you know, have a focus. So I am trying to focus more on biomarkers that, you know, we know that 70% patients will respond to EV-pembro, right? But what about the remaining 30%? Like, so I'm really trying to understand what determines hyperprogressors with such effective regimens who we really struggle with in the clinic. They really don't do well with anything we give them after that. So we are doing some work with that and also trying to focus on PROs and kind of patient-reported outcomes. And a special interest that I've now developed and working on it is young-onset bladder cancer. You know, the colorectal cancer world has made a lot of progress and we are really far behind. And bladder cancer has historically been a disease of the elderly, which is not the case anymore. We are seeing patients in their 30s and 40s. So we launched this young-onset bladder cancer initiative at a Bladder Cancer Advocacy Network meeting and now looking at more deep dive and creating a working group around that. But yeah, you know, I would say that my philosophy has been to just take the best out of the situation I'm in, no matter where I am. And it has just helped shape my career where I am, despite everything. Dr. Rafeh Naqash: Well, thank you again. It is always a pleasure to learn from your experiences and things that you have helped lead. Appreciate all your insights, and thank you for publishing with JCO PO. Hopefully we will see more of your biomarker work being published and perhaps bring you for another podcast in a couple of years. Dr. Shilpa Gupta: Yeah, thank you, Rafeh, for the opportunity. And thanks to JCO PO for making these podcasts for our readers. So thanks a lot. Dr. Rafeh Naqash: Thank you for listening to JCO Precision Oncology Conversations.

Guests Dr. Andrea Necchi, Dr. Ashish Kamat and host Dr. Davide Soldato discuss JCO article "End Points for the Next-Generation Bladder-Sparing Perioperative Trials for Patients With Muscle-Invasive Bladder Cancer," focusing on the evolving treatment landscape of MIBC (muscle-invasive bladder cancer) and the need to properly design novel trials investigating non-operative management while including the incorporation of biomarkers and patient perspectives in clinical trials. TRANSCRIPT The disclosures for guests on this podcast can be found in the show notes. Dr. Davide Soldato: Hello and welcome to JCO After Hours, the podcast where we sit down with authors from some of the latest articles published in the Journal of Clinical Oncology. I am your host, Dr. Davide Soldato, medical oncologist at Ospedale San Martino in Genoa, Italy. Today we are joined by JCO authors Andrea Necchi, Associate Professor of Medical Oncology at University San Raffaele and Medical Oncology at Ospedale San Raffaele in Milan, Italy, and Ashish Kamat, Professor of Urologic Oncology and Cancer Research at University of Texas MD Anderson Cancer Center. Both Professor Necchi and Professor Kamat are internationally recognized experts in the field of genitourinary malignancy and particularly in bladder cancer. Today we will be discussing the article titled "Endpoints for the Next Generation Bladder-Sparing Perioperative Trials for Patients with Muscle-Invasive Bladder Cancer." So thank you for speaking with us, Professor Necchi and Professor Kamat. Dr. Andrea Necchi: Thank you, Davide, and thank you JCO for the opportunity. Dr. Ashish Kamat: Yeah, absolutely. It is a great honor and privilege to be discussing this very important article with you. So thank you for the invitation. Dr. Davide Soldato: The article that you just published in JCO reports the results of a consensus meeting that was held among experts in the field of genitourinary malignancy and particularly for bladder cancer. So the objective was really to define endpoints for a novel generation of trials among patients diagnosed with muscle-invasive bladder cancer. So my first question would be: what is the change in clinical practice and in clinical evidence that we have right now that prompted the start of such consensus in 2025? Dr. Andrea Necchi: So, we are living so many changes in the treatment paradigm of patients with muscle-invasive bladder cancer. In general, patients diagnosed with bladder cancer or urothelial cancer today, thanks to the advent of immunotherapy or immunotherapy combinations, and today thanks to the advent of novel antibody-drug conjugates like enfortumab vedotin in combination with immunotherapy that are actually changing the landscape of treatment of patients with metastatic disease and also are entering quite fast into the treatment paradigm of patients with organ-confined disease with a lot of clinical trials testing these combination therapies, neoadjuvantly or adjuvantly, before or after radical cystectomy. Having said that, by potentiating the efficacy of systemic therapy, an increasing number of patients that receive neoadjuvant therapy of any kind, at a certain point in time, result to have achieved a deep response to systemic therapy, evaluated radiologically with conventional imaging, CT scan or MRI, or with cystoscopy or with other urology-based techniques, urinary cytology, and so. And based on the fact that they achieve a complete response, so no residual viable disease after systemic therapy, they raise concern about the fact that they have to undergo surgery like radical cystectomy that is quite impactful for their quality of life and for the future of their lives after the surgery. So the point that the patients are raising, and the patients are raising this point, is primarily due to the efficacy of systemic therapy. And we have seen so many cases fortunately achieving a deep response. So the question about what to do with the patient that at a certain point, at the start with the commitment to radical cystectomy, but at a certain point in time change their mind towards something else if possible, depending on the fact that they have achieved a deep response, is something that is a question and is a need to which we have to provide data, information, and guidance in general to the patients. Dr. Davide Soldato: If we look at the population that the recommendations were formulated for, we are mainly speaking about patients who would be fit for cystectomy, and this is a very distinct population compared to those who are not fit for cystectomy, both from a medical oncology point of view but also from a urologic point of view in terms of surgery. So, can you explain a little bit to our listeners why you think that this distinction is critical and why you developed this recommendation especially for this population? Dr. Ashish Kamat: That is a very important distinction that you made. To build upon what Professor Necchi mentioned earlier, this question that we get from patients after neoadjuvant therapy or systemic therapy is not a new question. It has been something that they have been asking us for the last 20 or 30 years. "Do I really need to have my bladder taken out?" And patients who are especially not fit for surgery will sometimes say, "Do I need to have my bladder taken out? And if I cannot have my bladder taken out, am I going to just not have anything done?" Because the eligibility for radical cystectomy is also a moving target. Over the years with improvement in surgical technique, improvement in perioperative therapy, ERAS protocols, et cetera, it is really unusual for us to deny a patient the opportunity to have major surgery unless clearly they have very significant comorbid conditions. So I think this endeavor is more broadly encompassing of the patient population than what was evident in previous years. And I really want to give a shout out to Professor Necchi because what we did was, as part of the International Bladder Cancer Group and Professor Necchi is an integral part of the scientific advisory board, we broached this topic broadly during one of our discussions. And of course, Andrea always does this, he picks on a topic and then he says, "Okay, we need to discuss this really in detail," put together a multinational, multicenter collaborative group, but the driving force was our patients. Because our patients are constantly asking, "Do I need to lose my organ? Do I need to have radiation therapy?" which again, also, has a lot of side effects. So this was really to answer the question in today's day and age as to do we need to do local consolidation, and if so, in what way? It is not a new question, but we have newer therapies, newer technology, and better ways to answer this. So it is a much needed question that needs to be answered. And I think the distinction between non-surgical candidates and surgical candidates is a little bit blurred in today's day and age. Dr. Davide Soldato: What about the eligibility, for example, for cisplatin-based chemotherapy? Because I think that that is a very fundamental part of this type of strategy that we apply to patients with muscle-invasive bladder cancer. So we know that there are some caveats for proposing such treatment. And also this population was specifically defined inside this recommendation. Dr. Andrea Necchi: I think that the focus of our work is just to analyze what is happening after any type of systemic therapy the patient may get neoadjuvantly. So it is not actually a question of treatment eligibility or including cisplatin eligibility. This is an old question of today's practice and clinical trials. But regardless of what the patient received neoadjuvantly, the point that we have addressed in our consensus meeting was what to do next as a further step after systemic therapy or not. So basically we are- the consensus guidance includes all-comers, so patients to get any type of systemic therapy. So really non-selected based on specific features that determine a special eligibility to a special or a particular therapy. But an all-comer approach is always the winning approach for the translation to be in practice, an all-comer approach just focusing on what has happened after treatment and that we are assessing by the use of conventional imaging, MRI or CT, cystoscopy, urinary cytology, and trying to merge all together this information, all these features in a unique, shared, reliable definition of clinical complete response that could be used as a biomarker for the selection of newer therapies instead of pathological response that has been historically used, and maybe surrogate for the outcome, the long-term outcome and survival of these patients. Dr. Davide Soldato: A very specific point of the consensus was actually the definition of clinical complete response. As you were saying, this is actually a combination of several parameters including urinary cytology, the use of cross-sectional imaging, for example CT scan, but also the evaluation in cystoscopy of the bladder. Do you foresee any potential problems when applying this type of recommendation, not inside clinical trials, but in the context of routine clinical practice? Dr. Ashish Kamat: Absolutely. And that was the whole reason we had this consensus meeting. What happens nowadays in daily practice, and we see this every day at our center, we see patients referred to us. This definition or this sort of attempt to define clinical complete response is an ongoing issue. And urologists, medical oncologists, radiation oncologists are always looking to see, does my patient have a complete response? That definition and those paradigms have changed and evolved over the years. The FDA had a workshop many years ago looking at this very question. And it was to address the proposal that complete clinical response, which is a clinical definition, a clinical state, does this correlate with pathologic response? And with the technology and the systemic therapies we had then, the answer was 'no'. In fact, more patients got recurrent disease than did not get recurrent disease. And that is why, of course in the paper we mention the trials that looked at this question, the trials that evolved around this question. And I think the distinction between a clinical trial and daily practice is extremely important when we are looking at this definition per se. Because essentially what happens with this issue is that if the patient is not appropriately counseled, and if the physician does not do the appropriate clinical complete response assessment as Professor Necchi mentioned, right, cystoscopy, cytology, imaging, use of markers that are still in evolvement, we risk doing harm to the patient. So we caution in the paper too that this definition is not ready for prime time use. It is something that needs to be studied. It is a rigorous definition and currently we are recommending it for clinical trials. I am sure eventually it will trickle down into clinical practice, but that guidance was not the purpose of this consensus meeting. Dr. Davide Soldato: There are several parameters that are potentially evolving and could potentially enter inside of clinical practice. For example, you mentioned pelvic MRI and we have now very specific criteria, the VI-RADS criteria, we're able actually to diagnose and also to provide information. So along with these novel imaging techniques, we also know that there are novel biomarkers that could be explored, for example ctDNA and urinary DNA. So what I was wondering is, why were not these included inside the definition that you provide for clinical complete response? And do you think that, as we are designing these trials to potentially spare cystectomy for this patient, we should include these biomarkers very early so that we can actually provide better stratification for our patients and really propose this type of cystectomy-sparing strategy only to those where we are very confident that we have obtained a clinical complete response? Dr. Andrea Necchi: I would say you have just to wait. So a follow-up is ongoing and hard work is ongoing. At the time we met, at the time we established the meeting in mid-December last year, we had no information on the ctDNA data from major trials, with only a few exceptions. So we were just at the beginning of a story that was more than likely to change but still without numbers and without data from clinical trials. Now in just nine months or 10 months time, we have accumulated important data and newer data will be presented during just a few weeks and a few days regarding the ctDNA, circulating tumor DNA in particular, as a prognostic marker assessed baseline or assessed after neoadjuvant therapy. So the point is certainly well made and ctDNA is certainly well shaped to be incorporated in a future definition of clinical complete response. But you have to consider the fact that most of the data that we are accumulating related to ctDNA are about the post-cystectomy field or the metastatic field. So regarding neoadjuvant therapy, you know, we have neoadjuvant therapy in the context of bladder-sparing approach, basically we have no information. And the point that is emerging in our daily practice when using these biomarkers or in clinical trials, and the impression in general, is that it is a very strong biomarker associated with survival, but we absolutely do not know what is the performance of the test in the prediction of superficial bladder relapses, high-grade pTa relapse in the bladder that is left untouched in the patient. We are considering, and maybe it will be just a matter of further discussion, not just what is happening within the immediate endpoint of clinical CR, but also what is happening later with other survival endpoints. And for example, when looking at the type of events that we may see in this kind of bladder-sparing approaches, most of the events, also in the trials that have been published including the RETAIN study published in JCO, most of the events are related to superficial high-grade superficial non-muscle invasive relapses. So the ability to predict these types of events with ctDNA is completely unknown. Maybe, maybe other liquid biomarkers like urinary tumor DNA, utDNA, could be a bit better shaped in the prediction of this kind of events, you know. But we have still to build the story. So the question is good. The answer is yes, we will likely, more than likely incorporate liquid biomarkers in the definition, but we have to wait at least more data and more robust data in order to translate this information in routine practice, you know. Another consensus meeting is organized by IBCG and the same folks for November. This meeting will be primarily focused on the liquid biomarkers, the interpretation and use and approval and so of liquid biomarkers including bladder cancer. And we will likely be able to address all these, most of these open issues, so most of these points in the next meetings. Dr. Davide Soldato: In the consensus you say that probably clinical complete response is now ready to be included in early phase trials, so actually to test what is the efficacy of the regimens that is being evaluated inside of these trials. But you actually do very in-depth work of defining what are the most appropriate endpoints for later phase trials. So to be very specific, the phase three registrational trials that bring new regimens inside of this space. So I just wanted to hear a little bit about what was the definition for event-free survival, which you define as the most appropriate one for this type of trials. And as you were mentioning before, Professor Necchi, there is a very specific interest on the type of events that we observe, especially when we look at these superficial relapses inside of the bladder. So was this a very urgent matter of debate as we define which type of events should actually trigger event-free survival? And did you make a very thoughtful decision about why using this type of endpoint instead of others, for example metastasis-free survival? Dr. Ashish Kamat: Yeah, this was a matter of intense debate as you might imagine. And again, this is a moving target. So as Professor Necchi mentioned, we tend to partner with each other, our organizations, on having definitions of clinical complete response, biomarker, retreats, and then using that as a marker, and you might imagine this definition of what is appropriate event-free survival, what events matter to the patient, is something we have been talking about for two years. It was not just something that came up at the retreat. But at the retreat there was intense discussion. One of the things that we talked about was bladder-intact event-free survival because we are trying to spare the patient's bladder. And do we count bladder-intact event-free survival as something that is relevant? The patient advocates absolutely liked that, right? They wanted that. But then we also learned from some of the studies, for example from the RETAIN study, that the non-muscle invasive recurrences can actually lead to metastatic disease. It is not as benign when you have a patient with muscle-invasive bladder cancer that then develops a non-invasive tumor because maybe there is cancer growing underneath the surface that we don't detect when we look in the bladder. So a lot of those discussions were held, debated. It was a consensus. I have to say it was not 100% agreement on that particular definition, but it was broad consensus. And Andrea, do you want to clarify a little bit as to how we came about that consensus? Because I think this is a very important point we need to make. Dr. Andrea Necchi: We focused on a bit different definition of BI-EFS, Bladder-Intact Event-Free survival. Just stating EFS as an all-inclusive parameter including all type of high-grade relapse or progression or death that may happen to the patient. So that we were counting high-grade pTa, pT1, CIS relapses to the bladder and of course more deeper involvement in the muscle layer and so, and metastatic disease as a relapse. But the point is that as compared to the classical bladder-intact EFS definition of chemoradiation bladder-sparing approaches that is including muscle-invasive relapses only or death as events, we tried to be as inclusive as possible in order to be as much conservative as possible and to raise as higher the bar as possible for the success. And this is actually what the patients are asking us. So they are asking, "Okay, I can save my bladder, sparing radical cystectomy, but at which cost?" So in order to provide an answer, we have to be very, very cautious and be on the right shape, on the right position to say, "Okay, we have accomplished the most, the safest points, you know, by which you can proceed with the bladder-sparing." This is the first point. The other point is related to the MFS, metastasis-free survival that you have mentioned. For sure, it was recognized as a very important point for sure. But in the discussion was clear that our focus was in saving patients, curing the patient, and saving the bladder. Any single event, superficial event that may occur in the bladder-saving approaches of this kind may expose the patient to an extra risk of developing distant metastases, as it happened for example in the RETAIN study. So EFS defined as we have agreed and published, is actually a way of including or anticipating in a safest position the MFS. Because most or if not the entirety of the events of metastasis development in patients undergoing bladder-sparing after neoadjuvant systemic therapy were preceded by a superficial phase of disease relapse, you know. So I remember very, very few, or we can count just on the finger of one hand, the cases that have been reported in the literature developing de novo metastatic disease in the similar bladder-sparing approaches, in particular when using a maintenance immunotherapy strategy, you know, after they reach TURBT. So this is the reason why with all the limitation that Ashish has mentioned, with all the uncertainties that are still there, the nervousness that is still there, EFS, as defined in the protocol, as put in the paper, is to us at the moment is the safest way to use a primary endpoint in potentially registration trials of this kind with perioperative systemic therapy and response-adapted surgery. Dr. Ashish Kamat: And David, just to be absolutely clear for our listeners, right, so what was the event-free survival that we defined? Essentially it was a very inclusive definition. Event was defined as high-grade tumor persistence, recurrence, or progression during or after perioperative therapy, and receipt of any additional standard of care treatment including radical cystectomy, radiotherapy or even intravesical therapy. So this was done at the behest of our patient advocates because we really wanted to make a very robust definition that could be utilized appropriately as an adequate primary endpoint for both early and late phase bladder preservation trials. Dr. Davide Soldato: I think that it really highlights one of the points that I liked the most about this consensus is that it really incorporated the patient vision and a sort of shared decision making process when we are deciding how we want to design these trials that will explore this bladder-sparing surgery. And Professor Necchi mentioned something that I think will be also a very interesting question for trials that will be developed considering the activity of this combination that we are seeing right now, which is maintenance. Because right now our approach in the few cases where patients do not do any type of treatments after an induction with neoadjuvant treatments is basically represented by observation. So I was wondering if you think that the field will actually evolve to a sort of maintenance strategy even in patients that will achieve a complete clinical response? Dr. Andrea Necchi: We just mentioned briefly in the paper, this is a very important point that was touched during the discussion, and in particular was raised and discussed by FDA people participating in the meeting. And when looking at the data from the trials that were available and are still available thus far, we could provide a suggestion that maintenance immune therapy is the preferred approach in this kind of approach as it currently stands, as the data currently stand. Because the cleanest data towards the successful part of this journey is related to the studies that provided a kind of maintenance therapy, like the study with nivolumab or the RETAIN-2 study with maintenance immune therapy instead of RETAIN study that was just stopping treatment until surgery with MVAC chemotherapy. So in general the impression is that maintenance therapy may help in reducing the type of events, including the events that we incorporate in the EFS definition that we mentioned in the paper. The point that you mentioned is very important because on the other side we have a problem, a big problem of affordability and cost of the treatment. The de-escalation trials are an urgent need and represent a call for the studies. Unfortunately, as you mentioned, this is something that moves beyond the possibilities of this type of consensus because we don't have data and we have to accumulate data from clinical trials prior to saying, "Okay, certain patients could de-escalate therapy and stop therapy and some other not." So we are still at the very beginning. So we can do- we can discuss about this in the radical cystectomy paradigm but not in the bladder-sparing paradigm, you know. But this is for sure a point, a discussion point that will be taken, pretty well taken in one year or two year projection. Dr. Davide Soldato: I was wondering if in the consensus, considering that patient advocates and patient associations were also involved, did you decide to actually suggest the inclusion of patient-reported outcomes or the evaluation of shared decision-making in the development of this trial really as endpoints that should matter as much or as much as possible as event-free survival and clinical complete response? Dr. Ashish Kamat: Oh yeah, absolutely. We had patient advocates, we had the World Bladder Cancer Patient Coalition, Bladder Cancer Advocacy Network, patient representatives. And we always consider this. Shared decision-making is actually the impetus behind why these efforts have been launched, right? So it is the shared decision-making that is very, very important. It is the driving force behind what we do. And it is worth noting, for example, for the design of such studies, regulatory agencies consider response-based endpoints or overall survival as primary endpoints. But the patient advocates consider quality of life to be just as important, if not more important sometimes than overall survival numbers. Because patient advocates will say, "Well if I live longer but I'm miserable living longer, yes that works for regulatory agencies but doesn't work for us." So PROs clearly are very, very important. And, in fact, we just literally had a meeting in Houston, the IBCG meeting where PROs were a main point of what we discussed. So incorporating PROs in everything we do, not just this but everything we do, Dr. Necchi, myself, everybody involved in these fields realizes it is very, very important. So absolutely.

In today's episode, filmed live at the 43rd Annual Chemotherapy Foundation Symposium, lung cancer expert Benjamin P. Levy, MD, hosted a cross-specialty discussion with genitourinary (GU) cancer expert Scott T. Tagawa, MD, MS, FACP, FASCO, about the rapidly evolving treatment paradigms for prostate and kidney cancer. Dr Levy is the clinical director of medical oncology at the Johns Hopkins Sidney Kimmel Cancer Center at Sibley Memorial Hospital and an associate professor of oncology at the Johns Hopkins University School of Medicine in Washington, DC. Dr Tagawa is a professor of medicine and urology at Weill Cornell Medicine, as well as an attending physician at NewYork-Presbyterian – Weill Cornell Medical Center in New York, New York. Their conversation began with a focus on prostate-specific membrane antigen (PSMA)–positive prostate cancer. Dr Tagawa explained that PSMA is a cell surface protein, and that PSMA imaging agents are commonly used to assess biochemical recurrence and perform initial disease staging. He noted that therapy-related adverse effects are often site-specific, including dry mouth/change in taste, and myelosuppression from the radiation payload. For monitoring long-term safety, Dr Tagawa emphasized that renal function must be tracked. Beyond PSMA, other prostate cancer targets include TROP-2, B7-H3, and markers specific to aggressive or neuroendocrine variants, such as DLL3, he reported. In advanced GU cancers, circulating tumor DNA (ctDNA) testing is increasingly important, Dr Tagawa highlighted. In prostate cancer, ctDNA testing is used to assess homologous recombination deficiency (HRD) status and BRCA expression, he said, explaining that evidence for the use of ctDNA testing in GU cancers stems from findings with this type of assay to evaluate minimal residual disease levels in urothelial cancer. He noted that studies show that if patients with urothelial cancer become ctDNA positive within the first year of receiving neoadjuvant chemotherapy, they benefit from treatment with atezolizumab (Tecentriq). Similarly, he stated that patients with previously untreated HRD-positive metastatic prostate cancer also see a progression-free survival benefit when a PARP inhibitor is added to an androgen deprivation therapy/androgen receptor pathway inhibitor backbone. Shifting the conversation to the management of frontline advanced clear cell renal cell carcinoma (RCC), the experts reviewed standard approaches, which involve an immune-oncology (IO) agent plus either a CTLA-4 inhibitor or a VEGF TKI. Tagawa noted that IO/VEGF TKI combinations may be preferred for symptomatic patients needing a rapid response, whereas IO/IO combinations may offer greater potential for treatment cessation. He brought up a key distinction in RCC, which is that re-instituting PD-1/PD-L1 inhibition upon progression in the metastatic setting has generally shown no benefit. Dr Levy brought a broad scope to the GU cancer discussion through his lung cancer expertise, introducing parallels between the treatment paradigms. The interview provided an opportunity to show the importance of creating connections across oncology specialties to bring nuanced perspectives to future advances in clinical research and patient care.

Two Onc Docs, hosted by Samantha A. Armstrong, MD, and Karine Tawagi, MD, is a podcast dedicated to providing current and future oncologists and hematologists with the knowledge they need to ace their boards and deliver quality patient care. Dr Armstrong is a hematologist/oncologist and assistant professor of clinical medicine at Indiana University Health in Indianapolis. Dr Tawagi is a hematologist/oncologist and assistant professor of clinical medicine at the University of Illinois in Chicago. In this episode, OncLive On Air® partnered with Two Onc Docs to review exciting updates from the 2025 ESMO Congress about bladder cancer management that have the potential to change guidelines. In non–muscle-invasive bladder cancer (NMIBC), 2 trials added immunotherapy to BCG. The phase 3 POTOMAC trial (NCT03528694) combining durvalumab (Imfinzi) with BCG for high-risk, BCG-naive NMIBC was positive, demonstrating improved disease-free survival with the combination. This regimen might become a new standard of care and could reduce the need for early radical cystectomy, the experts highlighted. For muscle-invasive bladder cancer, the phase 3 KEYNOTE-905 study (NCT03924895) combined perioperative enfortumab vedotin-ejfv (Padcev) and pembrolizumab (Keytruda) for cisplatin-ineligible patients. This positive trial demonstrated strong event-free survival and overall survival (OS) with the combination. Furthermore, the phase 3 IMvigor011 trial (NCT04660344) provided data on a risk-adapted approach using adjuvant atezolizumab (Tecentriq) for post-cystectomy patients with circulating tumor DNA (ctDNA)–positive disease. For these patients, atezolizumab generated benefits in disease-free survival and OS, supporting the future use of ctDNA for personalized therapy. Updates in metastatic bladder cancer emphasized the importance of testing for FGFR alterations and HER2 expression in the second-line setting, Armstrong and Tawagi explained. The phase 1 FORAGER-1 study (NCT05614739) showed the efficacy of an oral FGFR3 inhibitor in heavily pretreated patients and showed lower rates of hypophosphatemia with the agent compared with erdafitinib (Balversa). Overall, the conference yielded many new and exciting data points for the treatment of patients with bladder cancer.

Dr. Pedro Barata and Dr. Aditya Bagrodia discuss the evolving landscape of testicular cancer survivorship, the impact of treatment-related complications, and management strategies to optimize long-term outcomes and quality of life. TRANSCRIPT:  Dr. Pedro Barata: Hello and welcome to By the Book, a podcast series from ASCO that features engaging conversations between editors and authors of the ASCO Educational Book. I'm Dr. Pedro Barata. I'm a medical oncologist at University Hospitals Seidman Cancer Center and associate professor of medicine at Case Western Reserve University in Cleveland, Ohio. I'm also an associate editor of the ASCO Educational Book. We all know that testicular cancer is a rare but highly curable malignancy that mainly affects young men. Multimodal advances in therapy have resulted in excellent cancer specific survival, but testicular cancer survivors face significant long term treatment related toxicities which affect their quality of life and require surveillance and management. With that, I'm very happy today to be joined by Dr. Aditya Bagrodia, a urologic oncologist, professor, and the GU Disease Team lead at UC San Diego[KI1]  Health, and also the lead author of the recently published paper in the ASCO Educational Book titled, "Key Updates in Testicular Cancer: Optimizing Survivorship and Survival." And he's also the host of the world-renowned BackTable Urology Podcast. Dr. Bagrodia, I'm so happy that you're joining us today. Welcome. Dr. Aditya Bagrodia: Thanks, Pedro. Absolutely a pleasure to be here. Really appreciate the opportunity. Dr. Pedro Barata: Absolutely.  So, just to say that our full disclosures are available in the transcript of this episode.  Let's get things started. I'm really excited to talk about this. I'm biased, I do treat testicular cancer among other GU malignancies and so it's a really, really important topic that we face every day, right? Fortunately, for most of these patients, we're able to cure them. But it always comes up the question, "What now? You know, scans, management, cardio oncology, what survivorship programs we have in place? Are we addressing the different survivorship piece, psychology, fertility, et cetera?" So, we'll try to capture all of that today. Aditya, congrats again, you did a fantastic job putting together the insights and thoughts and what we know today about this important topic. And so, let's get focused specifically about what happens when patients get cured. So, many of us, in many centers, were fortunate enough to have these survivorship programs together, but I find that sometimes from talking to colleagues, they're not exactly the same thing and they don't mean the same thing to different people, to different institutions, right? So, first things first. What do you tell a patient perhaps when they ask you, "What can happen to me now that I'm done with treatment for testicular cancer?" Whether it's chemotherapy or just surgery or even radiation therapy? "So, what about the long term? What should I expect, Doctor, that might happen to me in the long run?" Dr. Aditya Bagrodia: Totally. I mean, I think that question's really front and center, Pedro, and really appreciate you all highlighting this topic. It was an absolute honor to work with true thought leaders and the survivorship bit of it is front and center, in my opinion. It's really the focus, you know, we, generally speaking should be able to cure these young men, but it's the 10, 15, 20 years down the way that they're going to largely contend with. The conversation really begins at diagnosis, pre-education. Fortunately, the bulk of patients that present are those with stage one disease, and even very basic things like before orchiectomy, talking about a prosthetic; we know that that can impact body image and self esteem, whether or not they decide to receive it or not. Actually, just being offered a prosthetic is important and this is something, you know, for any urologist, it's kind of critical. To discussing fertility elements to this, taking your time to examine the contralateral testicle, ask about fertility problems, issues, concerns, offer sperm banking, even in the context of a completely normal contralateral testicle, I think these things are quite important.  So if it's somebody with stage one disease, you know, without going too far down discussing adjuvant therapy and so forth, I will start the conversation with, "You know, the testes do largely two things. They make testosterone and they make sperm." By and large, patients are going to be able to have acceptable levels of testosterone, adequate sperm parameters to maintain kind of a normal gonadal state and to naturally conceive, should that be something they're interested in. However, there's still going to be, depending on what resource you look at, somewhere in the order of 10-30% that are going to have issues. Where I think for the stage one patients, it's really incumbent upon us is actually to not wait for them to discuss their concerns, particularly with testosterone, which many times can be a little bit vague, but to proactively ask about it every time. Libido, erectile quality, muscle mass maintenance, energy, fatigue. All of these are kind of associated symptoms of hypogonadism. But for a lot of kids 18-20 years old, it's going to be something insidious that they don't think about. So, for the stage one patients, it absolutely starts with gonadal function. If they are stage two getting surgery, I think the counseling really needs to center around a possibility for ejaculatory dysfunction. Now, for a chemotherapy-naive, nerve-sparing RPLND, generally these days we should be able to preserve ejaculatory function at high volume centers, but you still want to bring that up and again kind of touch base on thinking about sperm banking and so forth before the operation, scars, those are things I think worth talking about, small risk of ascites. Then, I think the intensity of potential long term adverse effects really ramps up when we're talking about systemic therapy, chemotherapy. And then there's of course some radiation therapy specific elements that come up. So, for the chemotherapy bits of it, I really think this is going to be something that can be a complete multi-system affected intervention. So, anxiety, depression, our group has actually shown using some population resources that even suicidality can be increased among patients that have been treated for germ cell tumor. You know, really from the top down, tinnitus, hearing changes, those are things that we need to ask about at every appointment. Neuropathy, sexual health, that we kind of talked about, including ED (erectile dysfunction), vertigo, dizziness, Raynaud's phenomenon, these are kind of more the symptoms that I think we need to inquire about every time. And what we do here and I think at a lot of survivorship programs is use kind of a battery of validated instruments, germ cell tumor specific, platinum treated patient specific. So we use a combination of EORTC questions and PROMIS questions, which actually serves as like a review of systems for the patient, also as a research element. We review that and then depending on what might be going on, we can dig into that further, get them over to colleagues in audiology or psychology, et cetera.  And then of course, screening for the hypertension, hyperlipidemia, metabolic syndrome with basically you or myself or somebody kind of like us serving, many times it's the role of the PCP, just making sure we're checking out, you know, CBC, CMP, et cetera, lipid parameters to screen for those kind of cardiac associated issues along with secondary malignancies. Dr. Pedro Barata: So that's super comprehensive and thorough. Thank you so much. Actually, I love how you break it down in a simple way. Two functions of the testes, produce testosterone and then, you know, the problem related to that is the hypogonadism, and then the second, as you mentioned, produce sperm and of course related to the fertility issues with that.  So, let's start with the first one that you mentioned. So, you do cite that in your paper, around 5-10% of men end up getting, developing hypogonadism, maybe clinical when they present with symptoms, maybe subclinical. So, I'm wondering, for our audience, what kind of recommendations we would give for addressing that or kind of thinking of that? How often are you ordering those tests? And then, when you're thinking about testosterone replacement therapy, is that something you do immediately or are there any guidelines into context that? How do you approach that? Dr. Aditya Bagrodia: So, just a bit more on digging into it even in terms of the questions to ask, you know, "Do you have any decrease in sexual drive? Any erectile dysfunction? Are your morning erections still taking place? Has the ejaculate volume changed? Physically, muscle mass, strength? Have you been putting on weight? Have you noticed increase in body fat?" And sometimes this is complicated because there's some anxiety that comes along with a cancer diagnosis when you're 20, 30 years old, multifactorial, hair loss, hot flashes, irritability. Sometimes they'll, you know, literally they'll say, "You know, my significant other or partners noticed that I'm really just a little bit labile." So I think, you know, there's the symptoms and then checking, usually kind of a gonadal panel, FSH, LH, free and total testosterone, sex hormone binding globulin, that's going to be typically pretty comprehensive. So if you've got symptoms plus some laboratory work, and ideally that pre-orchiectomy testosterone gives you some delta. If they started out at an 800, 900, now they're 400, that might be a big change for them. And then, when you talk about TRT (Testosterone Replacement Therapy) recommendations, you know, Pedro, yourself, myself, we're kind of lucky to be at academic centers and we've got men's health colleagues that are ultra experts, but at a high level, I would say that a lot of the TRT options center around fertility goals. Exogenous testosterone treats the low T, but it does suppress gonadal function, including spermatogenesis. So if that's not a priority, they can just get TRT. It should be done under the care of a urologist, a men's health, an endocrinologist, where we're checking liver chemistries and CBCs and a PSA and so forth. If they're interested in fertility preservation, then I would say engaging an endocrinologist, men's health expert is important. There's medications even like hCG, Clomid, which works centrally and stimulate the gonadal access. Niche scenarios where they might want standard TRT now, and then down the way, 5, 7 years, they're thinking about coming off of that for fertility purposes, I think that's really where you want to have an expert involved because there's quite a bit of nuance there in recovery of actual spermatogenesis and so forth.  To kind of summarize, you got to ask about it. Checking it is, is not overly complicated. We do a baseline pre-orchiectomy and at least once annually, you can tag it in with the tumor markers, so it's not an extra blood draw. And if they have symptoms of course, kind of developed, then we'll move that up in the evaluation. Dr. Pedro Barata: Got it. And you also touch base on the fertility angle, which is truly important. And I'm just curious, you know, a lot of times many of us might see one, two patients a year, right, and we forget these protocols and what we've got to do about that.  And so I'm interested to hear your thoughts about when you think about fertility, and how proactive you get. In other words, who do you refer for the fertility clinic, for a fertility preservation program? You know, do all cases despite getting through orchiectomy or just the cases that you're going to, you know you're going to seek chemotherapy at some point? What kind of selection or it depends on the chemo, like how do you do that assessment about the referral for preservation program that you might have available at UCSD? Dr. Aditya Bagrodia: Yeah, I mean I feel really fortunate to sit on the NCCN Testis Cancer Guidelines. It's in there that fertility counseling should be discussed prior to orchiectomy. So 100% bring it up. If there are risk factors, undescended testicles, previous history of fertility concerns, atrophic contralateral testicle, anything on the ultrasound like microlithiasis in the contralateral testicle, you kind of wanna get it there. And then again, there's kind of niche scenarios where you're really worried, maybe get a semen analysis and it doesn't look that good, arrange for the time of orchiectomy to have onco-testicular sperm extraction from the, quote unquote, "normal" testis parenchyma. You know, I think you have to be kind of prepared to go that route and really make sure you're doing this completely comprehensively.  So pre-orchiectomy all patients. Don't really push for it too hard if they've got a contralateral testicle, if they've had no issues having children. There's some cost associated with this, sperm banking still isn't kind of covered even in the context of men with cancer. If they've got risk factors, absolutely pre-orchiectomy. Pre-RPLND, even though the rates of ejaculatory dysfunction at a high-volume center should be low single digits, I'll still offer it. That'd be a real catastrophe if they were in that small proportion of patients and now they're going to be reliant on things like intrauterine insemination, where it becomes quite expensive.  Pre-chemo, everybody. That's basically a standard these days where it should be discussed and it's kind of amazing currently, even if you don't have an accessible men's health fertility clinic, there are actually companies, I have no vested interest, Fellow is one such company where you can actually create an account, receive a FedEx semen analysis and cryopreservation kit, send it back in, and all CLIA certified, it's based out of California. The gentleman that runs it, is a urologist and very, very bright guy who's done a lot of great stuff for testis cancer. So, even for patients that are kind of in extremis at the hospital that kind of need to get going like yesterday, we still discuss it. We've got some mechanisms in place to either have them take a semen analysis over to our Men's Health clinic or send it off to Fellow, which I think is pretty cool and that even extends to some of our younger adolescent patients where going to a clinic and providing a sample might be tricky.  So, I think bringing it up every stage, anytime there's an intervention that might be offered, orchiectomy, chemo, surgery, radiation, it's kind of incumbent on us to discuss it. Dr. Pedro Barata: Gotcha. That's super helpful. And you also touch base on another angle, which is the psychosocial angle around this. You mentioned suicidal rates, you mentioned anxiety, perhaps depression in some cases as well as chronic fatigue, not necessarily just because of the low testosterone that you can get, but also from a psychological perspective. I'm curious, what do the recommendations look like for that? Do these patients need to see a social worker or a psychologist, or do they need to answer a screening test every time they come to see us and then based on that, we kind of escalate, take the next steps according to that? Do they see a psychologist perhaps every so often? How should that be managed and addressed? Dr. Aditya Bagrodia: It's an excellent question and again, these can be rather insidious symptoms where if you don't really dig in and inquire, they can be glossed over. I mean, how easy to say, "Your markers look okay, your scans look okay. See you in six months," and keep it kind of brief. First off, I think bringing it up proactively and normalizing it, that, "This may be something that you experience. Many people do, you're not alone, there's nothing kind of wrong with you." I also think that this is an area where support groups can be incredibly useful. We host the Testicular Cancer Awareness Foundation support group here. They'll talk about chemo brain or just like a little bit of an adjustment disorder after their diagnosis. Support groups, I think are critical. As I mentioned, we have a survivorship program that's led by a combination of our med oncs, myself on the uro-onc side, as well as APPs, where we are systematically asking about essentially the whole litany of issues that may arise, including psychosocial, anxiety, depression, suicidality. And we've got a nice kind of fast path into our cancer center support services for these young men to meet with a psychologist. If that isn't going to be sufficient, they can actually see a psychiatrist to discuss medications and so forth. I do think that we've got to screen for these because, as anticipated from diagnosis, those first 2 years, we see a rise. But even 10, 15 years out, we note, compared to controls, that there is an increased level of anxiety, depression, suicidality that might not just take place at that initial acute period of diagnosis and treatment. Dr. Pedro Barata: Really well said. Super important.  So I guess if I were to put all these together, with these really amazing advances in technology, we all know AI, some of us might be more or less aware of biomarkers coming up, including microRNA for example, and others, like as I think of all these potential long term complications for these patients, look at the future, I guess, can we use this as a way to deescalate treatment where it's not really necessary, as a way to actually prevent some of these complications? Like, how do we see where we're heading? As we manage testicular cancer, let's say, within the next 5 or 10 years, do you think there's something coming up that's going to be different from what we're doing things today? Dr. Aditya Bagrodia: Totally. I mean, I think it's as exciting as a time as there's ever been, you know, maybe notwithstanding circa 1970s when platinum was discovered. So microRNAs, which you mentioned, you know, there's a new candidate biomarker, microRNA-371. We are super excited here at UCSD. We actually have it CLIA-certified available in our lab and are ordering these tests for patients kind of in their acute stage, you know, stage one and surveillance, stage two, post-RPLND, receiving chemotherapy. And essentially this is a universal germ cell tumor specific biomarker, except for teratoma, suffice it to say 90% sensitive and specific. And I think it's going to change the way that we diagnose and manage patients. You know, pre-orchiectomy, that's pretty straightforward. Post-orchiectomy, maybe we can really decrease the number of CT scans that are done. Maybe we can identify those patients that basically have occult disease where we can intervene early, either with RPLND or single cycle chemo. Post-RPLND, identify the patients who are at higher risk of relapse that may benefit from some adjuvant therapy. In the advanced setting, look at marker decline for patients in addition to standard tumor markers. Can we modulate their systemic therapy?  So, the international interest is largely on modifying things. There's really cool clinical trials that we have for stage one patients, that treatment would be prescribed based on a post-orchiectomy microRNA. I think the microRNAs are really exciting. Teratoma remains an outstanding question. I think this is where maybe ctDNA, perhaps some radiomics and advanced imaging processing and incorporating AI may allow us to safely avoid a lot of these post-chemo RPLNDs. And then identification using SNPs and so forth of who might be most susceptible to some of the cardiac toxicity, autotoxicity and personalizing things in that way as well. Dr. Pedro Barata: Super exciting, right, what's about to come? And I agree with you, I think it's going to change dramatically how we manage this disease.  This has been a pleasure sitting down with you. I guess before letting you go, anything else you'd like to add before we wrap it up? Dr. Aditya Bagrodia: Yeah, first off, again, just want to thank you and ASCO for the opportunity. And it's easy enough to, I think, approach a patient with the testicular germ cell tumor as, "This is an easy case. We're just going to do whatever we've done. Go to the guidelines that says do X, Y, or Z." But there's so much more nuance to it than that. Getting it done perfectly, I think, is mandatory. Whatever we do is an impact on them for the next 50, 60, 70 years of their life. And I found the germ cell tumor community, people are really passionate about it. If you're ever uncertain, there's experts throughout the country and internationally. Ask somebody before you do something that you can't undo. I think we owe it to them to get it perfect so that we can really maximize the survivorship and the survival like we've been talking about. Dr. Pedro Barata: Aditya, thanks for sharing your fantastic insights with us on this podcast. Dr. Aditya Bagrodia: All right, Pedro. Fantastic. Appreciate the opportunity.

JCO PO author Dr. Asaf Maoz at Dana-Farber Cancer Institute shares insights into article, “Causes of Death Among Individuals with Lynch Syndrome in the Immunotherapy Era.” Host Dr. Rafeh Naqash and Dr. Maoz discuss the causes of death in individuals with LS and the evolving role of immunotherapy. 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 Associate Professor Medicine, at the OU Health Stephenson Cancer Center. Today, I'm super thrilled to be joined by Dr. Asaf Maoz, Medical Oncologist at Dana-Farber Cancer Institute, Brigham and Women's Hospital, and faculty at the Harvard Medical School, and also lead author on the JCO Precision Oncology article entitled "Causes of Death Among Individuals with Lynch Syndrome in the Immunotherapy Era." This publication will be a concurrent publication with an oral presentation at the annual CGA meeting. At the time of this recording, our guest's disclosures will be linked in the transcript. Asaf, I'm excited to welcome you on this podcast. Thank you for joining us today. Dr. Asaf Maoz: Thank you so much for highlighting our paper. Dr. Rafeh Naqash: Absolutely. And I was just talking to you that we met several years back when you were a trainee, and it looks like you've worked a lot in this field now, and it's very exciting to see that you consider JCOPO as a relevant home for some of your work. And the topic that you have published on is of significant interest to trainees from a precision medicine standpoint, to oncologists in general, covers a lot of aspects of immunotherapy. So, I'm really excited to talk to you about all of this. Dr. Asaf Maoz: Me too, me too. And yeah, I think JCOPO has great content in the area of cancer genetics and has done a lot to disseminate the knowledge in that area. Dr. Rafeh Naqash: Wonderful. So, let's get started and start off, given that we have hosts of different kinds of individuals who listen to this podcast, especially when driving from home to work or back, for the sake of making everything simple, can we start by asking you what is Lynch syndrome? How is it diagnosed? What are some of the main things to consider when you're trying to talk an individual where you suspect Lynch syndrome? Dr. Asaf Maoz: Lynch syndrome is an inherited predisposition to cancer, and it is common. So, we used to think that, or there's a general notion in the medical community that it is a rare condition, but we actually know now from multiple studies, including studies that look at the general population and do genetic testing regardless of any clinical phenotype, that Lynch syndrome is found in about 1 in 300 people in the general population. If you think about it in the United States, that means that there are over a million people living with Lynch syndrome in the United States. Unfortunately, most individuals with Lynch syndrome don't know they have Lynch syndrome at the current time, and that's where a lot of the efforts in the community are being made to help detect more individuals who have Lynch syndrome. Lynch syndrome is caused by pathogenic germline variants in mismatch repair genes, MLH1, MSH2, MSH6, or PMS2, or as a result of pathogenic variants in EPCAM that cause silencing of the MSH2 gene. Dr. Rafeh Naqash: Excellent. Thank you for that explanation. Now, one of the other things I also realized, similar to BRCA germline mutations, where you require a second hit for individuals with Lynch syndrome to have mismatch repair deficient cancers, you also require a second hit to have that second hit result in an MSI-high cancer. Could you help us understand the difference of these two concepts where generally Lynch syndrome is thought of to be cancers that are mismatch repair deficient, but that's not necessarily true for all cases as we see in your paper. Can you tease this out for us a little bit more? Dr. Asaf Maoz: Of course, of course. So, the germline defect is in one of the mismatch repair genes, and these genes are responsible for DNA mismatch repair, as their name implies. Now, in a normal cell, we think that one working copy is generally enough to maintain the mismatch repair machinery intact. What happens in tumors, as you alluded to, is that there is a second hit in the same mismatch repair gene that has the pathogenic germline variant, and that causes the mismatch repair machinery not to work anymore. And so what happens is that there is formation of mutations in the cancer cell that are not present in other cells in the body. And we know that there are specific types of mutations that are associated with defects in mismatch repair mechanisms, and those are associated a lot of times with frameshift mutations. And we have termed them ‘microsatellites'. So there are areas in the genome that have repeats, for example, you know, if you have AAAA or GAGA, and those areas are particularly susceptible to mutations when the mismatch repair machinery is not working. And so we can measure that with DNA microsatellite instability testing. But we can also get a sense of whether the mismatch repair machinery is functioning by looking at protein expression on the surface of cancer cells and by doing immunohistochemistry. More recently, we're also able to infer whether the mismatch repair machinery is working by doing next-generation sequencing and looking at many, many microsatellites and whether they have this DNA instability in the microsatellites. Dr. Rafeh Naqash: Excellent explanation. As a segue to what you just mentioned, and this reminds me of some work that one of my good friends, collaborators, Amin Nassar, whom you also know, I believe, had done a year and a half back, was published in Cancer Cell as a brief report, I believe, where the concept was that when you look at these mismatch repair deficient cancers, there is a difference between NGS testing, IHC testing, and maybe to some extent, PCR testing, where you can have discordances. Have you seen that in your clinical experience? What are some of your thoughts there? And if a trainee were to ask, what would be the gold standard to test individuals where you suspect mismatch repair deficient-related Lynch syndrome cancers? How would you test those individuals? Dr. Asaf Maoz: We do sometimes see discordance, you know, from large series, the concordance rate is very high, and in most series it's over 95%. And so from a practical perspective, if we're thinking about the recommendation to screen all colorectal cancer and all endometrial cancer for mismatch repair deficiency, I think either PCR-based testing or immunohistochemistry is acceptable because the concordance rate is very high. There are rare cases where it is not concordant, doing multiple of the tests makes sense at that time. If you think about the difference between the tests, the immunohistochemistry looks at protein expression, which is a surrogate for whether there is mismatch repair deficiency or not, right? Because ultimately, the mismatch repair deficiency is manifested in the mutations. So if the PCR does not show microsatellite instability and now NGS does not show microsatellite instability, the IHC may be a false positive. At the end of the day, the functional analysis of whether there are actually unstable microsatellites either by PCR or by NGS is what I would consider more informative. But IHC again is an excellent test and concordant with those results in over 95% of cases. Now there is also an issue of sampling. It's possible that there's heterogeneity within the tumor. We published a case in JCOPO about heterogeneity of the mismatch repair status, and that was both by immunohistochemistry, but also by PCR. So there are some caveats and interpreting these tests does require some expertise, and I'm always happy to chat with trainees or whoever has an interesting or challenging case. Dr. Rafeh Naqash: Thanks again for that very easy to understand explanation. Now going to management strategies, could you elaborate a little bit upon the neo-adjuvant data currently, or the metastatic data which I think more people are familiar with for immunotherapy in individuals with MSI-high cancers? Dr. Asaf Maoz: Yeah, that's an excellent question and obviously a very broad topic. Individuals with Lynch syndrome typically develop tumors that are mismatch repair deficient or microsatellite unstable. And we have seen over the last 15 years or so that these tumors, because they have a lot of mutations and because these mutations are very immunogenic, we have seen that they respond very well to immunotherapy. And this has been shown across disease sites and has been shown across disease settings. And for that reason, immunotherapy was approved for MSI-high or mismatch repair deficient cancer regardless of the anatomic site. It was the first tissue-agnostic approval by the FDA in 2017. And so there are exciting studies both in the metastatic setting where we see individuals who respond to immunotherapy for many years, and one could wonder whether their cancer is going to come back or not. And also in the earlier setting, for example, the Cercek et al. study in the New England Journal from Sloan Kettering, where they showed that neoadjuvant immunotherapy can cause durable responses for rectal cancer that is mismatch repair deficient. And in that series, the patients did not require surgery or radiation, which is standard of care for rectal cancer otherwise. And there's also exciting data in the adjuvant space, as was presented in ASCO by Dr. Sinicrope, the ATOMIC study, and many more efforts to bring immunotherapy into the treatment landscape for individuals with MSI-high cancer, including individuals with Lynch syndrome. Dr. Rafeh Naqash: A lot of activity, especially in the neo-adjuvant and adjuvant space over the last two years or so. Now going to the actual reason why we are here is your study. Could you tell us why you looked at this idea of patients who had Lynch syndrome and died, and the reasons for their death? What was the thought that triggered this project? Dr. Asaf Maoz: As we were talking about, we now know that immunotherapy really has changed the treatment landscape for individuals with Lynch syndrome, and that most cancers that individuals with Lynch syndrome do have this mismatch repair deficiency. But we also know that individuals with Lynch syndrome can develop tumors that do not have mismatch repair deficiency, and we call them mismatch repair proficient or microsatellite stable. And there was a series from Memorial Sloan Kettering showing that in colorectal cancer, about 10% of the tumors that individuals with Lynch syndrome developed did not have mismatch repair deficiency. In addition to that, we anecdotally saw that some of our patients with Lynch syndrome died of causes that were not mismatch repair deficient tumors. We wanted to see how that has changed since immunotherapy was approved in a tissue-agnostic manner, meaning that we could look at this regardless of where the cancer started, because we would anticipate that if the tumor was mismatch repair deficient, the patient would be able to access immunotherapy as standard of care. Dr. Rafeh Naqash: Thank you. And then you looked at different aspects of correlations with regards to individuals that had an MSI-high cancer with Lynch syndrome or an MSS cancer with Lynch syndrome. Could you elaborate on some of the important findings that you identified as well as some of the unusual findings that perhaps we did not know about, even though the sample size is limited, but what were some of the unique things that you did identify through this project? Dr. Asaf Maoz: The first question was what cause is leading to death in individuals with Lynch syndrome? And we had 54 patients that we identified that had died since the approval of immunotherapy in 2017, 44 of which died of cancer-related causes. And when we looked at cancer-related causes of death, we wanted to know how many of those were due to mismatch repair deficient tumors versus mismatch repair proficient tumors or MS-stable tumors. And we found, somewhat surprisingly, that 43% of patients in our cohort actually died of tumors that were microsatellite stable or mismatch repair proficient, meaning of tumors that are not typically associated with Lynch syndrome. This is not entirely surprising as a cause of death because we know that immunotherapy does not typically work for tumors that are microsatellite stable. And so in the metastatic setting, there are much less cases of durable remissions with treatment. But it was helpful to have that figure as an important benchmark. There are previous studies about causes of death in Lynch syndrome, and particularly from the Prospective Lynch Syndrome Database in Europe. Those have provided really important information about cause of death by cancer site, but they typically don't have mismatch repair status and are more difficult to interpret in that regard. They also don't include a large number of individuals who have PMS2 Lynch syndrome, which is the most common, but least penetrant form of Lynch syndrome. Dr. Rafeh Naqash: As far as the subtype of pathogenic germline variants is concerned, did you notice anything unusual? And I've always had this question, and you may know more about this data, is: In the bigger context of immunotherapy, does the type of the pathogenic germline variant for Lynch syndrome associated MSI-high cancers, does that impact or have an association with the kind of outcomes, how soon a cancer progresses or how many exceptional responders perhaps with MSI-high cancers actually have a certain specific pathogenic germline variant? Dr. Asaf Maoz: That's an excellent question, and certainly we need more data in that space. We know that the type of germline mutation, or the gene in which there is a germline pathogenic variant, determines to a large degree the cancer risk, right? So we know that individuals who have germline pathogenic variants in MLH1 or MSH2 have a much higher colorectal cancer risk than, for example, PMS2. We know that for PMS2, the risks are more limited to colorectal and endometrial, and may be lower risk of other cancers. We also know that, you know, the spectrum of disease may change based on the pathogenic germline variants. For example, individuals who have MSH2 associated Lynch syndrome have more risk of additional cancers in other organs like the urinary tract and other less common Lynch-associated tumors. The question about response to therapy is one where we have much less information. There are studies that are trying to assess this, but I don't think the answer is there yet. Some of the non-clinical data looks at how many mutations there are based on the pathogenic variant and what the nature of those mutations are, whether they're more frameshift or others. But I think we still need more clinical data to understand whether the response to immunotherapy differs. It's also complicated by the fact that the immunotherapy landscape is changing, especially in the metastatic setting, now with the approval of combination ipilimumab and nivolumab for first-line treatment of colorectal cancer that is microsatellite unstable. But in our study, we did find that, as you would expect, there is an enrichment in MS-stable cancers among those with PMS2 Lynch syndrome. Again, our denominator is those who died, right? So this is not the best way to look at the question whether this is overall true, that is more addressed by the study that Sloan Kettering published. But we do see, as we would anticipate, that there are more microsatellite stable cancers among those with PMS2 Lynch syndrome that died. Dr. Rafeh Naqash: A lot to uncover there for sure. This study and perhaps some of the other work that you're doing is slowly advancing our understanding of some of these concepts. So I'd like to shift gears to a couple of provocative questions that I generally like to ask. The first is, in your opinion, and you may or may not have data to back this up, which is okay, and that's why we're having a conversation about it. In your opinion, do you think the type or the quality of the neoantigen is different based on the pathogenic germline variant and a Lynch syndrome associated MSI-high cancer? Dr. Asaf Maoz: I think there are some data out there that, you know, I can't cite off the top of my mind, but there are some data out there that suggest that that may be the case. I think the key question is the quality, right? I think that whether these differences that are found on a molecular level also translate to a clinical difference in response is something that is unknown at this moment. Some people hypothesize that if the tumor has less neoantigens, there's less of a response to immunotherapy. But I think we really need to be careful before making those assertions on a clinical level. I do think it's a really important question that needs to be answered, among others because, you know, in the colorectal space, for example, where we have both the option of doing ipilimumab with nivolumab and the option of doing pembrolizumab, we don't really know which patients need the CTLA-4 blockade versus which patients can receive PD-1 blockade alone and avoid the potential excess toxicity of the CTLA-4 blockade. There are a lot of interesting questions there that still need to be answered. And of course, individuals with Lynch syndrome are just a fraction of those individuals who have MSI-high cancer. So there's also the question about whether non-Lynch syndrome associated MSI-high cancer responds differently to immunotherapy than Lynch syndrome associated MSI-high cancer. A lot of very interesting questions in the field for sure. Dr. Rafeh Naqash: Absolutely. My second question is more about trying to understand the role of ctDNA, MRD monitoring in individuals with Lynch syndrome. If somebody has a germline, you know, Lynch syndrome MSI-high cancer, when you do a tumor-informed ctDNA assessment, what do you capture generally there? Because, and this question stems from a discussion I've had with somebody regarding EGFR lung cancer, since I treat individuals with lung cancer, and the concept generally is that even if the tissue showed EGFR, but for MRD monitoring, when you do a barcoded sequence of different tumor specific mutations, it's not actually the EGFR that they track in the blood when they do ctDNA assessment. But from a Lynch syndrome standpoint, if you have a germline, right, which is the first hit, and then you have the somatic in the tumor, which is the second hit, are you aware or have you tried to look into this where what is exactly being followed if one had to follow MRD in a Lynch syndrome MSI-high colorectal cancer? Dr. Asaf Maoz: I think a lot of the MRD assays are proprietary, and so we don't receive information about what the mutations that are being tracked are. In general, the idea is to track mutations that we would not expect to disappear as part of resistant mechanisms. We want these to be truncal mutations. We want these to be mutations in which resistance is not expected to result in reversion mutations. But what specifically is being tracked is something that I don't know because these assays, the tumor-informed ones, are proprietary, and we don't get the results regarding specific mutations. When it's circulating tumor DNA that is not necessarily tumor-informed, we do get those results, but that is less so about the specific selection of mutations. Dr. Rafeh Naqash: Thank you for clarifying that question to some extent, of course, as you said, we don't know a lot, and we don't know what we don't know. That's the most important thing that I've learned in the process of understanding precision medicine and genomics, and it's a very fast-paced evolving field. Last question related to your project, what is the next step? Are you planning any next steps as a bigger multicenter study or validation of some sort? Dr. Asaf Maoz: There are two big questions that this study raises. One, is this true across multiple other sites, right? Because this is a single center study, and we really need additional centers to look at their data and validate whether they are also seeing that a substantial portion of deaths in individuals with Lynch syndrome are attributable to mismatch repair proficient cancer. The other question is whether we can look at specifically MSI-high cancer versus MS-stable cancer and understand what the mortality rate for each of those are. From a clinical perspective, it's important to counsel individuals with Lynch syndrome about general cancer screening outside of mismatch repair deficient tumors and to understand that there is also a risk of mismatch repair proficient tumors and that treatment for those tumors would be different. There's a lot of work to be done in the future. Another major area of need is to see whether tumors that are microsatellite stable can be sensitized to immunotherapy, and that is beyond the Lynch syndrome field, but that is something that certainly would benefit these individuals with Lynch syndrome who develop mismatch repair proficient cancer. Dr. Rafeh Naqash: That's very interesting to hear, and we'll look forward to seeing some of those developments shape in the next few years. Now, I'd like to spend a minute, minute and a half on you specifically as a researcher, clinician, scientist. Could you briefly highlight - because I remember meeting you several years back as a trainee, with your interest in genomics, computational research - could you briefly tell us what led you to hereditary cancer syndromes based on your research and work? What are some of the things that you learned along the way that other early career investigators can perhaps take lessons from? Dr. Asaf Maoz: Big questions there, thanks for asking. I got interested in the field of hereditary cancer syndromes when I came to the United States and started doing lab research in Stephen Gruber's lab at the time at USC. He's now at City of Hope. And my interest was originally looking at immunotherapy and immunology, but I went to the case conferences where we were learning about individuals with hereditary cancer, and those were kind of earlier days where we were still trying to figure out how to test and what the implications for these individuals would be. And through fellowship, I was also very interested in that, and I did my senior fellowship years with Dr. Yurgelun here at Dana-Farber, who is the director of the Lynch Syndrome Center. And I I think it's the combination between being able to treat individuals based on precision medicine and what the germline mutation is, but also the ability to prevent cancer and to develop strategies to intercept cancer early that is really appealing to me in this field. It's also a great field to be in because it's a small field. If you come to the CGA-IGC meeting, you'll be able to interact with everyone. Everyone is super collaborative, super nice, and I really recommend it to trainees. The CGA-IGC annual meeting is really a great opportunity to learn more and experience some of the advancement specifically in the GI hereditary space. Lessons for trainees. I think there are a lot of lessons that I could think about, but I think finding strong and supportive mentors is one of the things that has helped me most. I think that just having close relationship with your mentor, having frequent discussions and honest discussions about what is feasible, what is going to make a difference for your patients and your research and what you want to focus on is really important. And so I think if I had to choose one thing, I would say choose a mentor that you trust, that you feel you have a good relationship with, and that has the availability to support you. Dr. Rafeh Naqash: Thank you so much for those insightful comments, and thank you for sharing with us your journey, your project, and some of your interesting thoughts on this concept of hereditary cancers. Hopefully, we'll see more of this work being published in JCOPO through your lab or work from others. Dr. Asaf Maoz: Thank you so much. I appreciate the opportunity to be here.

Dr. Diwakar Davar and Dr. Jason Luke discuss novel agents in melanoma and other promising new data in the field of immunotherapy that were presented at the 2025 ASCO Annual Meeting. TRANSCRIPT Dr. Diwakar Davar: Hello. My name is Diwakar Davar, and I am welcoming you to the ASCO Daily News Podcast. I'm an associate professor of medicine and the clinical director of the Melanoma and Skin Cancer Program at the University of Pittsburgh's Hillman Cancer Center. Today, I'm joined by my colleague and good friend, Dr. Jason Luke. Dr. Luke is a professor of medicine. He is also the associate director of clinical research and the director of the Phase 1 IDDC Program at the University of Pittsburgh's Hillman Cancer Center. He and I are going to be discussing some key advancements in melanoma and skin cancers that were presented at the 2025 ASCO Annual Meeting. Our full disclosures are available in the transcript of this episode.  Jason, it is great to have you back on the podcast. Dr. Jason Luke: Thanks again so much for the opportunity, and I'm really looking forward to it. Dr. Diwakar Davar: Perfect. So we will go ahead and start talking a little bit about a couple of key abstracts in both the drug development immunotherapy space and the melanoma space. The first couple of abstracts, the first two, will cover melanoma. So, the first is LBA9500, which was essentially the primary results of RELATIVITY-098. RELATIVITY-098 was a phase 3 trial that compared nivolumab plus relatlimab in a fixed-dose combination against nivolumab alone for the adjuvant treatment of resected high-risk disease. Jason, do you want to maybe give us a brief context of what this is? Dr. Jason Luke: Yeah, it's great, thanks. So as almost all listeners, of course, will be aware, the use of anti–PD-1 immunotherapies really revolutionized melanoma oncology over the last 10 to 15 years. And it has become a standard of care in the adjuvant setting as well. But to review, in patients with stage III melanoma, treatment can be targeted towards BRAF with BRAF and MEK combination therapy, where that's relevant, or anti–PD-1 with nivolumab or pembrolizumab are a standard of care. And more recently, we've had the development of neoadjuvant approaches for palpable stage III disease. And in that space, if patients present, based on two different studies, either pembrolizumab or nivolumab plus ipilimumab can be given prior to surgery for somewhere in the 6- to 9-week range. And so all of these therapies have improved time-to-event endpoints, such as relapse-free or event-free survival. It's worth noting, however, that despite those advances, we've had a couple different trials now that have actually failed in this adjuvant setting, most high profile being the CheckMate-915 study, which looked at nivolumab plus ipilimumab and unfortunately was a negative study. So, with RELATIVITY-047, which was the trial of nivolumab plus relatlimab that showed an improvement in progression-free survival for metastatic disease, there's a lot of interest, and we've been awaiting these data for a long time for RELATIVITY-098, which, of course, is this adjuvant trial of LAG-3 blockade with relatlimab plus nivolumab. Dr. Diwakar Davar: Great. So with that, let's briefly discuss the trial design and the results. So this was a randomized, phase 3, blinded study, so double-blinded, so neither the investigators knew what the patients were getting, nor did the patients know what they were getting. The treatment investigational arm was nivolumab plus relatlimab in the fixed-dose combination. So that's the nivolumab standard fixed dose with relatlimab that was FDA approved in RELATIVITY-047. And the control arm was nivolumab by itself. The duration of treatment was 1 year. The patient population consisted of resected high-risk stage III or IV patients. The primary endpoint was investigator-assessed RFS. Stage and geography were the standard stratifying factors, and they were included, and most of the criteria were balanced across both arms. What we know at this point is that the 2-year RFS rate was 64% and 62% in the nivolumab and nivolumab-combination arms, respectively. The 2-year DMFS rate was similarly equivalent: 76% with nivolumab monotherapy, 73% with the combination. And similar to what you had talked about with CheckMate 915, unfortunately, the addition of LAG-3 did not appear to improve the RFS or DMFS compared to control in this patient population. So, tell us a little bit about your take on this and what do you think might be the reasons why this trial was negative? Dr. Jason Luke: It's really unfortunate that we have this negative phase 3 trial. There had been a lot of hope that the combination of nivolumab with relatlimab would be a better tolerated combination that increased the efficacy. So in the metastatic setting, we do have 047, the study that demonstrated nivolumab plus relatlimab, but now we have this negative trial in the adjuvant setting. And so as to why exactly, I think is a complicated scenario. You know, when we look at the hazard ratios for relapse-free survival, the primary endpoint, as well as the secondary endpoints for distant metastasis-free survival, we see that the hazard ratio is approximately 1. So there's basically no difference. And that really suggests that relatlimab in this setting had no impact whatsoever on therapeutic outcomes in terms of efficacy. Now, it's worth noting that there was a biomarker subanalysis that was presented in conjunction with these data that looked at some immunophenotyping, both from circulating T cells, CD8 T cells, as well as from the tumor microenvironment from patients who were treated, both in the previous metastatic trial, the RELATIVITY-047 study, and now in this adjuvant study in the RELATIVITY-098 study. And to briefly summarize those, what was identified was that T cells in advanced melanoma seemed to have higher expression levels of LAG-3 relative to T cells that are circulating in patients that are in the adjuvant setting. In addition to that, there was a suggestion that the magnitude of increase is greater in the advanced setting versus adjuvant. And the overall summary of this is that the suggested rationale for why this was a negative trial may have been that the target of LAG-3 is not expressed as highly in the adjuvant setting as it is in the metastatic setting. And so while the data that were presented, I think, support this kind of an idea, I am a little bit cautious that this is actually the reason for why the trial was negative, however. I would say we're not really sure yet as to why the trial was negative, but the fact that the hazard ratios for the major endpoints were essentially 1 suggests that there was no impact whatsoever from relatlimab. And this really makes one wonder whether or not building on anti–PD-1 in the adjuvant setting is feasible because anti–PD-1 works so well. You would think that even if the levels of LAG-3 expression were slightly different, you would have seen a trend in one direction or another by adding a second drug, relatlimab, in this scenario. So overall, I think it's an unfortunate circumstance that the trial is negative. Clearly there's going to be no role for relatlimab in the adjuvant setting. I think this really makes one wonder about the utility of LAG-3 blockade and how powerful it really can be. I think it's probably worth pointing out there's another adjuvant trial ongoing now of a different PD-1 and LAG-3 combination, and that's cemiplimab plus fianlimab, a LAG-3 antibody that's being dosed from another trial sponsor at a much higher dose, and perhaps that may make some level of difference. But certainly, these are unfortunate results that will not advance the field beyond where we were at already. Dr. Diwakar Davar: And to your point about third-generation checkpoint factors that were negative, I guess it's probably worth noting that a trial that you were involved with, KeyVibe-010, that evaluated the PD-1 TIGIT co-formulation of vibostolimab, MK-4280A, was also, unfortunately, similarly negative. So, to your point, it's not clear that all these third-generation receptors are necessarily going to have the same impact in the adjuvant setting, even if they, you know, for example, like TIGIT, and they sometimes may not even have an effect at all in the advanced cancer setting. So, we'll see what the HARMONY phase 3 trial, that's the Regeneron cemiplimab/fianlimab versus pembrolizumab control with cemiplimab with fianlimab at two different doses, we'll see how that reads out. But certainly, as you've said, LAG-3 does not, unfortunately, appear to have an impact in the adjuvant setting. So let's move on to LBA9501. This is the primary analysis of EORTC-2139-MG or the Columbus-AD trial. This was a randomized trial of encorafenib and binimetinib, which we will abbreviate as enco-bini going forward, compared to placebo in high-risk stage II setting in melanoma in patients with BRAF V600E or K mutant disease. So Jason, you know, you happen to know one or two things about the resected stage II setting, so maybe contextualize the stage II setting for us based on the trials that you've led, KEYNOTE-716, as well as CheckMate-76K, set us up to talk about Columbus-AD. Dr. Jason Luke: Thanks for that introduction, and certainly stage II disease has been something I've worked a lot on. The rationale for that has been that building off of the activity of anti–PD-1 in metastatic melanoma and then seeing the activity in stage III, like we just talked about, it was a curious circumstance that dating back about 7 to 8 years ago, there was no availability to use anti–PD-1 for high-risk stage II patients, even though the risk of recurrence and death from melanoma in the context of stage IIB and IIC melanoma is in fact similar or actually higher than in stage IIIA or IIIB, where anti–PD-1 was approved. And in that context, a couple of different trials that you alluded to, the Keynote-716 study that I led, as well as the CheckMate 76K trial, evaluated pembrolizumab and nivolumab, respectively, showing an improvement in relapse-free and distant metastasis-free survival, and both of those agents have subsequently been approved for use in the adjuvant setting by the US FDA as well as the European Medicines Agency.  So bringing then to this abstract, throughout melanoma oncology, we've seen that the impact of anti–PD-1 immunotherapy versus BRAF and MEK-targeted therapy have had very similar outcomes on a sort of comparison basis, both in frontline metastatic and then in adjuvant setting. So it was a totally reasonable question to ask: Could we use adjuvant BRAF and MEK inhibitor therapy? And I think all of us expected the answer would be yes. As we get into the discussion of the trial, I think the unfortunate circumstance was that the timing of this clinical trial being delayed somewhat, unfortunately, made it very difficult to accrue the trial, and so we're going to have to try to read through the tea leaves sort of, based on only a partially complete data set. Dr. Diwakar Davar: So, in terms of the results, they wanted to enroll 815 patients, they only enrolled 110. The RFS and DMFS were marginally improved in the treatment arm but certainly not significantly, which is not surprising because the trial had only accrued 16% to 18% of its complete accrual. As such, we really can't abstract from the stage III COMBI-AD data to stage II patients. And certainly in this setting, one would argue that the primary treatment options certainly remain either anti–PD-1 monotherapy, either with pembrolizumab or nivolumab, based on 716 or 76K, or potentially active surveillance for the patients who are not inclined to get treated.  Can you tell us a little bit about how you foresee drug development going forward in this space because, you know, for example, with HARMONY, certainly IIC disease is a part of HARMONY. We will know at least a little bit about that in this space. So what do you think about the stage IIB/C patient population? Is this a patient population in which future combinations are going to be helpful, and how would you think about where we can go forward from here? Dr. Jason Luke: It is an unfortunate circumstance that this trial could not be accrued at the pace that was necessary. I think all of us believe that the results would have been positive if they'd been able to accrue the trial. In the preliminary data set that they did disclose of that 110 patients, you know, it's clear there is a difference at a, you know, a landmark at a year. They showed a 16% difference, and that would be in line with what has been seen in stage III. And so, you know, I think it's really kind of too bad. There's really going to be no regulatory approach for this consideration. So using BRAF and MEK inhibition in stage II is not going to be part of standard practice moving into the future. To your point, though, about where will the field go? I think what we're already realizing is that in the adjuvant setting, we're really overtreating the total population. And so beyond merely staging by AJCC criteria, we need to move to biomarker selection to help inform which patients truly need the treatment. And in that regard, I don't think we've crystallized together as a field as yet, but the kinds of things that people are thinking about are the integration of molecular biomarkers like ctDNA. When it's positive, it can be very helpful, but in melanoma, we found that, unfortunately, the rates are quite low, you know, in the 10% to 15% range in the adjuvant setting. So then another consideration would be factors in the primary tumor, such as gene expression profiling or other considerations.  And so I think the future of adjuvant clinical trials will be an integration of both the standard AJCC staging system as well as some kind of overlaid molecular biomarker that helps to enrich for a higher-risk population of patients because on a high level, when you abstract out, it's just clearly the case that we're rather substantially overtreating the totality of the population, especially given that in all of our adjuvant studies to date for anti–PD-1, we have not yet shown that there's an overall survival advantage. And so some are even arguing perhaps we should even reserve treatment until patients progress. I think that's a complicated subject, and standard of care at this point is to offer adjuvant therapy, but certainly a lot more to do because many patients, you know, unfortunately, still do progress and move on to metastatic disease. Dr. Diwakar Davar: Let's transition to Abstract 2508. So we're moving on from the melanoma to the novel immunotherapy abstracts. And this is a very, very, very fascinating drug. It's IMA203. So Abstract 2508 is a phase 1 clinical update of IMA203. IMA203 is an autologous TCR-T construct targeting PRAME in patients with heavily pretreated PD-1-refractory metastatic melanoma. So Jason, in the PD-1 and CTLA-4-refractory settings, treatment options are either autologous TIL, response rate, you know, ballpark 29% to 31%, oncolytic viral therapy, RP1 with nivolumab, ORR about 30-ish percent. So new options are needed. Can you tell us a little bit about IMA203? Perhaps tell us for the audience, what is the difference between a TCR-T and traditional autologous TIL? And a little bit about this drug, IMA203, and how it distinguishes itself from the competing TIL products in the landscape. Dr. Jason Luke: I'm extremely enthusiastic about IMA203. I think that it really has transformative potential based on these results and hopefully from the phase 3 trial that's open to accrual now. So, what is IMA203? We said it's a TCR-T cell product. So what that means is that T cells are removed from a patient, and then they can be transduced through various technologies, but inserted into those T cells, we can then add a T-cell receptor that's very specific to a single antigen, and in this case, it's PRAME. So that then is contrasted quite a bit from the TIL process, which includes a surgical resection of a tumor where T cells are removed, but they're not specific necessarily to the cancer, and they're grown up in the lab and then given to the patient. They're both adoptive cell transfer products, but they're very different. One is genetically modified, and the other one is not. And so the process for generating a TCR-T cell is that patients are required to have a new biomarker that some may not be familiar with, which is HLA profiling. So the T-cell receptor requires matching to the concomitant HLA for which the peptide is bound in. And so the classic one that is used in most oncology practices is A*02:01 because approximately 48% of Caucasians have A*02:01, and the frequency of HLA in other ethnicities starts to become highly variable. But in patients who are identified to have A*02:01 genotype, we can then remove blood via leukapheresis or an apheresis product, and then insert via lentiviral transduction this T-cell receptor targeting PRAME. Patients are then brought back to the hospital where they can receive lymphodepleting chemotherapy and then receive the reinfusion of the TCR-T cells. Again, in contrast with the TIL process, however, these T cells are extremely potent, and we do not need to give high-dose interleukin-2, which is administered in the context of TIL. Given that process, we have this clinical trial in front of us now, and at ASCO, the update was from the phase 1 study, which was looking at IMA203 in an efficacy population of melanoma patients who were refractory at checkpoint blockade and actually multiple lines of therapy. So here, there were 33 patients and a response rate of approximately 50% was observed in this population of patients, notably with a duration of response approximately a year in that treatment group. And I realize that these were heavily pretreated patients who had a range of very high-risk features. And approximately half the population had uveal melanoma, which people may be aware is a generally speaking more difficult-to-treat subtype of melanoma that metastasizes to the liver, which again has been a site of resistance to cancer immunotherapy. So these results are extremely promising. To summarize them from what I said, it's easier to make TCR-T cells because we can remove blood from the patient to transduce the T cells, and we don't have to put them through surgery. We can then infuse them, and based on these results, it looks like the response rate to IMA203 is a little bit more than double what we expect from lifileucel. And then, whereas with lifileucel or TILs, we have to give high-dose IL-2, here we do not have to give high-dose IL-2. And so that's pretty promising. And a clinical trial is ongoing now called the SUPREME phase 3 clinical trial, which is hoping to validate these results in a randomized global study. Dr. Diwakar Davar: Now, one thing that I wanted to go over with you, because you know this trial particularly well, is what you think of the likelihood of success, and then we'll talk a little bit about the trial design. But in your mind, do you think that this is a trial that has got a reasonable likelihood of success, maybe even a high likelihood of success? And maybe let's contextualize that to say an alternative trial, such as, for example, the TebeAM trial, which is essentially a T-cell bispecific targeting GP100. It's being compared against SOC, investigator's choice control, also in a similarly heavily pretreated patient population. Dr. Jason Luke: So both trials, I think, have a strong chance of success. They are very different kinds of agents. And so the CD3 bispecific that you referred to, tebentafusp, likely has an effect of delaying progression, which in patients with advanced disease could have a value that might manifest as overall survival. With TCR-T cells, by contrast, we see a very high response rate with some of the patients going into very durable long-term benefit. And so I do think that the SUPREME clinical trial has a very high chance of success. It will be the first clinical trial in solid tumor oncology randomizing patients to receive a cell therapy as compared with a standard of care. And within that standard of care control arm, TILs are allowed as a treatment. And so it will also be the first study that will compare TCR-T cells against TILs in a randomized phase 3. But going back to the data that we've seen in the phase 1 trial, what we observe is that the duration of response is really connected to the quality of the response, meaning if you have more than a 50% tumor shrinkage, those patients do very, very well. But even in patients who have less than 50% tumor shrinkage, the median progression-free survival right now is about 4.5 months. And again, as we think about trial design, standard of care options for patients who are in this situation are unfortunately very bad. And the progression-free survival in that population is probably more like 2 months. So this is a trial that has a very high likelihood of being positive because the possibility of long-term response is there, but even for patients who don't get a durable response, they're likely going to benefit more than they would have based on standard chemotherapy or retreatment with an anti–PD-1 agent. Dr. Diwakar Davar: Really, a very important trial to enroll, a trial that is first in many ways. First of a new generation of TCR-T agents, first trial to look at cell therapy in the control arm, a new standard of efficacy, but potentially also if this trial is successful, it will also be a new standard of trial conduct, a new kind of trial, of a set of trials that will be done in the second-line immunotherapy-refractory space. So let's pivot to the last trial that we were going to discuss, which was Abstract 2501. Abstract 2501 is a first-in-human phase 1/2 trial evaluating BNT142, which is the first-in-class mRNA-encoded bispecific targeting Claudin-6 and CD3 in patients with Claudin-positive tumors. We'll talk a little bit about this, but maybe let's start by talking a little bit about Claudin-6. So Claudin-6 is a very interesting new target. It's a target that's highly expressed in GI and ovarian tumors. There are a whole plethora of Claudin-6-targeting agents, including T-cell bispecifics and Claudin-6-directed CAR-Ts that are being developed. But BNT142 is novel. It's a novel lipid nanoparticle LNP-encapsulated mRNA. The mRNA encodes an anti–Claudin-6 CD3 bispecific termed RiboMAB-021. And it then is administered to the patient. The BNT142-encoding mRNA LNPs are taken up by the liver and translated into the active drug. So Jason, tell us a little bit about this agent. Why you think it's novel, if you think it's novel, and let's talk a little bit then about the results. Dr. Jason Luke: So I certainly think this is a novel agent, and I think this is just the first of what will probably become a new paradigm in oncology drug development. And so you alluded to this, but just to rehash it quickly, the drug is encoded as genetic information that's placed in the lipid nanoparticle and then is infused into the patient. And after the lipid nanoparticles are taken up by the liver, which is the most common place that LNPs are usually taken up, that genetic material in the mRNA starts to be translated into the actual protein, and that protein is the drug. So this is in vivo generation, so the patient is making their own drug inside their body. I think it's a really, really interesting approach. So for any drug that could be encoded as a genetic sequence, and in this case, it's a bispecific, as you mentioned, CD3-Claudin-6 engager, this could have a tremendous impact on how we think about pharmacology and novel drug development moving into the future in oncology. So I think it's an extremely interesting drug, the like of which we'll probably see only more moving forward. Dr. Diwakar Davar: Let's maybe briefly talk about the results. You know, the patient population was heavily pretreated, 65 or so patients, mostly ovarian cancer. Two-thirds of the patients were ovarian cancer, the rest were germ cell and lung cancer patients. But let's talk a little bit about the efficacy. The disease control rate was about 58% in the phase 1 population as a whole, but 75% in the ovarian patient population. Now tell us a little bit about the interesting things about the drug in terms of the pharmacokinetics, and also then maybe we can pivot to the clinical activity by dose level. Dr. Jason Luke: Well, so they did present in their presentation at ASCO a proportionality showing that as higher doses were administered, that greater amounts of the drug were being made inside the patient. And so that's an interesting observation, and it's an important one, right? Suggesting that the pharmacology that we classically think of by administering drugs by IV, for example, would still be in play. And that did translate into some level of efficacy, particularly at the higher dose levels. Now, the caveat that I'll make a note of is that disease control rate is an endpoint that I think we have to be careful about because what that really means is sometimes a little bit unclear. Sometimes patients have slowly growing tumors and so on and so forth. And the clinical relevance of disease control, if it doesn't last at least 6 months, I think is probably pretty questionable. So I think these are extremely interesting data, and there's some preliminary sense that getting the dose up is going to matter because the treatment responses were mostly observed at the highest dose levels. There's also a caveat, however, that across the field of CD3 bispecific molecules like this, there's been quite a bit of heterogeneity in terms of the response rate, with some of them only really generating stable disease responses and other ones having more robust responses. And so I think this is a really interesting initial foray into this space. My best understanding is this molecule is not moving forward further after this, but I think that this really does set it up to be able to chase after multiple different drug targets on a CD3 bispecific backbone, both in ovarian cancer, but then basically across all of oncology. Dr. Diwakar Davar: Perfect. This is a very new sort of exciting arena where we're going to be looking at, in many ways, these programmable constructs, whether we're looking at in vivo-generated, in this case, a T-cell bispecific, but we've also got newer drugs where we are essentially giving drugs where people are generating in vivo CAR T, and also potentially even in vivo TCR-T. But certainly lots of new excitement around this entire class of drugs. And so, what we'd like to do at this point in time is switch to essentially the fact that we've got a very, very exciting set of data at ASCO 2025.

Dr. Neeraj Agarwal and Dr. Jeanny Aragon-Ching discuss important advances in the treatment of prostate, bladder, and kidney cancers that were presented at the 2025 ASCO Annual Meeting. TRANSCRIPT Dr. Neeraj Agarwal: Hello, and welcome to the ASCO Daily News Podcast. I am Dr. Neeraj Agarwal, your guest host of the ASCO Daily News Podcast today. I am 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 am delighted to be joined by Dr. Jeanny Aragon-Ching, a GU medical oncologist and the clinical program director of the GU Center at the Inova Schar Cancer Institute in Virginia. Today, we will be discussing some key abstracts in GU oncology that were presented at the 2025 ASCO Annual Meeting.  Our full disclosures are available in the transcript of this episode.  Jeanny, it is great to have you on the podcast. Dr. Jeanny Aragon-Ching: Oh, thank you so much, Neeraj. Dr. Neeraj Agarwal: Jeanny, let's begin with some prostate cancer abstracts. Let's begin with Abstract 5017 titled, “Phase 1 study results of JNJ-78278343 (pasritamig) in metastatic castration-resistant prostate cancer.” Can you walk us through the design and the key findings of this first-in-human trial? Dr. Jeanny Aragon-Ching: Yeah, absolutely, Neeraj. So this study, presented by Dr. Capucine Baldini, introduces pasritamig, a first-in-class T-cell redirecting bispecific antibody that simultaneously binds KLK2 on prostate cancer cells and CD3 receptor complexes on T cells. KLK2 is also known as human kallikrein 2, which is selectively expressed in prostate tissue. And for reference, KLK3 is what we now know as the PSA, prostate-specific antigen, therefore making it an attractive and specific target for therapeutic engagement. Now, while this was an early, first-in-human, phase 1 study, it enrolled 174 heavily pretreated metastatic CRPC patients. So many were previously treated with ARPIs, taxanes, and radioligand therapy. So given the phase 1 nature of this study, the primary objective was to determine the safety and the RP2D, which is the recommended phase 2 dose. Secondary objectives included preliminary assessment of antitumor activity. So, pasritamig was generally well tolerated. There were no treatment-related deaths. Serious adverse events were rare. And in the RP2D safety cohort, where patients received the step-up dosing up to 300 mg of IV every 6 weeks, the most common treatment-related adverse events were low-grade infusion reactions. There was fatigue and grade 1 cytokine release syndrome, what we call CRS. And no cases of neurotoxicity, or what we call ICANS, the immune effector cell-associated neurotoxicity syndrome, reported. Importantly, the CRS occurred in just about 8.9% of patients. All were grade 1. No patients required tocilizumab or discontinued treatment due to adverse events. So, this suggests a favorable safety profile, allowing hopefully for outpatient administration without hospitalization, which will be very important when we're thinking about bispecifics moving forward. In terms of efficacy, pasritamig showed promising activity. About 42.4% of evaluable patients achieved a PSA50 response. Radiographic PFS was about 6.8 months. And among patients with measurable disease, the objective response rate was about 16.1% in those with lymph node or bone metastases, and about 3.7% in those with visceral disease, with a median duration of response of about 11.3 months. So, altogether, this data suggests that pasritamig may offer a well-tolerated and active new potential option for patients with metastatic CRPC.   Again, as a reminder, with the caveat that this is still an early phase 1 study. Dr. Neeraj Agarwal: Thank you, Jeanny. These are promising results for a bispecific T-cell engager, pasritamig, in prostate cancer. I agree, the safety and durability observed here stand out, and this opens the door for further development, possibly even in earlier disease settings.  So, shifting now from immunotherapy to the evolving role of genomics in prostate cancer. So let's discuss Abstract 5094, a real-world, retrospective analysis exploring the prognostic impact of homologous recombination repair gene mutations, especially BRCA1 and BRCA2 mutations, in metastatic hormone-sensitive prostate cancer. Can you tell us more about this abstract, Jeanny? Dr. Jeanny Aragon-Ching: Sure, Neeraj. So this study was presented by Dr. David Olmos, represents one of the largest real-world analyses we have evaluating the impact of homologous recombination repair, or what we would call HRR, alterations in metastatic hormone-sensitive prostate cancer. So, this cohort included 556 men who underwent paired germline and somatic testing. Now, about 30% of patients had HRR alterations, with about 12% harboring BRCA1 or BRCA2 mutations and 16% having alterations in other HRR genes. Importantly, patients were stratified via CHAARTED disease volume, and outcomes were examined across treatment approaches, including ADT alone, doublet therapy, and triplet therapy. The prevalence of BRCA and HRR alterations were about similar between the metastatic hormone-sensitive prostate cancer and the metastatic castrate-resistant prostate cancer, with no differences observed, actually, between the patients with high volume versus low volume disease.  So, the key finding was that BRCA and HRR alterations were associated with poor clinical outcomes in metastatic hormone-sensitive prostate cancer. And notably, the impact of these alterations may actually be even greater in metastatic hormone-sensitive prostate cancer than previously reported in metastatic CRPC. So, the data showed that when BRCA mutations are present, the impact of the volume of disease is actually limited. So, poor outcomes were observed across the board for both high-volume and low-volume groups. So, the analysis showed that patients with HRR alterations had significantly worse outcomes compared to patients without HRR alterations. Median radiographic progression-free survival was about 20.5 months for the HRR-altered patients versus 30.6 months for the non-HRR patients, with a hazard ratio of 1.6. Median overall survival was 39 months for HRR-altered patients compared to 55.7 months for the non-HRR patients, with a hazard ratio of 1.5. Similar significant differences were observed when BRCA-mutant patients were compared with patients harboring non-BRCA HRR mutations. Overall, poor outcomes were independent of treatment of ARPI or taxanes. Dr. Neeraj Agarwal: Thank you, Jeanny. So, these data reinforce homologous recombination repair mutations as both a predictive and prognostic biomarker, not only in the mCRPC, but also in the metastatic hormone-sensitive setting as well. It also makes a strong case for incorporating genomic testing early in the disease course and not waiting until our patients have castration-resistant disease. Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. And I think this really brings home the point and the lead up to the AMPLITUDE trial, which is LBA5006, a phase 3 trial that builds on this very concept of testing with a PARP inhibitor, niraparib, in the hormone-sensitive space. Can you tell us a little bit more about this abstract, Neeraj? Dr. Neeraj Agarwal: Sure. So, the AMPLITUDE trial, a phase 3 trial presented by Dr. Gerhardt Attard, enrolled 696 patients with metastatic hormone-sensitive prostate cancer and HRR gene alterations. 56% of these patients had BRCA1 and BRCA2 mutations. Patients were randomized to receive abiraterone with or without niraparib, a PARP inhibitor. The majority of patients, 78% of these patients, had high-volume metastatic hormone-sensitive prostate cancer, and 87% of these patients had de novo metastatic HSPC. And 16% of these patients received prior docetaxel, which was allowed in the clinical trial. So, with a median follow-up of nearly 31 months, radiographic progression-free survival was significantly prolonged with the niraparib plus abiraterone combination, and median was not reached in this arm, compared to abiraterone alone, which was 29.5 months, with a hazard ratio of 0.63, translating to a 37% reduction in risk of progression or death. This benefit was even more pronounced in the BRCA1 and BRCA2 subgroup, with a 48% reduction in risk of progression, with a hazard ratio of 0.52. Time to symptomatic progression also improved significantly across all patients, including patients with BRCA1, BRCA2, and HRR mutations. Although overall survival data remain immature, early trends favored the niraparib plus abiraterone combination. The safety profile was consistent with prior PARP inhibitor studies, with grade 3 or higher anemia and hypertension were more common but manageable. Treatment discontinuation due to adverse events remained low at 11%, suggesting that timely dose modifications when our patients experience grade 3 side effects may allow our patients to continue treatment without discontinuation. These findings support niraparib plus abiraterone as a potential new standard of care in our patients with metastatic hormone-sensitive prostate cancer with HRR alterations, and especially in those who had BRCA1 and BRCA2 mutations. Dr. Jeanny Aragon-Ching: Thank you, Neeraj. This trial is especially exciting because it brings PARP inhibitors earlier into the treatment paradigm. Dr. Neeraj Agarwal: Exactly. And it is exciting to see the effect of PARP inhibitors in the earlier setting.  So Jeanny, now let's switch gears a bit to bladder cancer, which also saw several impactful studies. Could you tell us about Abstract 4502, an exploratory analysis from the EV-302 trial, which led to approval of enfortumab vedotin plus pembrolizumab for our patients with newly diagnosed metastatic bladder cancer? So here, the authors looked at the outcomes in patients who achieved a confirmed complete response with EV plus pembrolizumab. Dr. Jeanny Aragon-Ching: Sure, Neeraj. So, EV-302 demonstrated significant improvements in progression-free and overall survival for patients previously treated locally advanced or metastatic urothelial cancer, I'll just call it metastatic UC, as a frontline strategy, establishing EV, which is enfortumab vedotin, plus pembro, with pembrolizumab as standard of care in this setting.  So, this year at ASCO, Dr Shilpa Gupta presented this exploratory responder analysis from the phase 3 EV-302 trial. Among 886 randomized patients, about 30.4% of patients, this is about 133, in the EV+P arm, and 14.5% of the patients in the chemotherapy arm, achieved a confirmed complete response. They call it the CCR rates. So for patients who achieved this, median PFS was not reached with EV+P compared to 26.9 months with chemotherapy, with a hazard ratio of 0.36, translating to a 64% reduction in the risk of progression. Overall survival was also improved. So the median OS was not reached in either arm, but the hazard ratio favored the EV+P at 0.37, translating to a 63% reduction in the risk of death. The median duration of complete response was not reached with EV+P compared to 15.2 months with chemotherapy. And among those patients who had confirmed CRs at 24 months, 78% of patients with the EV+P arm remained progression-free, and around 95% of the patients were alive, compared to 54% of patients who were progression-free and 86% alive of the patients in the chemotherapy arm. Safety among responders were also consistent with prior reports. Grade 3 or higher treatment-related adverse events occurred in 62% of EV+P responders and 72% of chemotherapy responders. Most adverse events were managed with dose modifications, and importantly, no treatment-related deaths were reported among those who were able to achieve complete response.  So these findings further reinforce EV and pembro as the preferred first-line therapy for metastatic urothelial carcinoma, offering a higher likelihood of deep, durable responses with a fairly manageable safety profile. Dr. Neeraj Agarwal: Thank you for the great summary, Jeanny. These findings underscore the depth and durability of responses achievable with this combination and also suggest that achieving a response may be a surrogate for long-term benefit in patients with metastatic urothelial carcinoma.  So now, let's move to Abstract 4503, an exploratory ctDNA analysis from the NIAGARA trial, which evaluated perioperative durvalumab, an immune checkpoint inhibitor, in muscle-invasive bladder cancer. So what can you tell us about this abstract? Dr. Jeanny Aragon-Ching: Absolutely, Neeraj. So, in NIAGARA, presented by Dr. Tom Powles, the addition of perioperative durvalumab to neoadjuvant chemotherapy, gem/cis, significantly improved event-free survival, overall survival, and pathologic complete response in patients with cisplatin-eligible muscle-invasive bladder cancer. Recall that this led to the U.S. FDA approval of this treatment regimen on March 28, 2025.  So, a planned exploratory analysis evaluated the ctDNA dynamics and their association with clinical outcomes, which was the one presented recently at ASCO. So, the study found that the incidence of finding ctDNA positivity in these patients was about 57%. Following neoadjuvant treatment, this dropped to about 22%, with ctDNA clearance being more common in the durvalumab arm, about 41%, compared to the chemotherapy control arm of 31%. Notably, 97% of patients who remained ctDNA positive prior to surgery failed to achieve a pathologic CR. So, this indicates a strong association between ctDNA persistence and lack of tumor eradication. So, postoperatively, only about 9% of patients were ctDNA positive. So, importantly, durvalumab conferred an event-free survival benefit regardless of ctDNA status at both baseline and post-surgery. Among patients who were ctDNA positive at baseline, durvalumab led to a hazard ratio of 0.73 for EFS. So, this translates to a 27% reduction in the risk of disease recurrence, progression, or death compared to the control arm. In the post-surgical ctDNA-positive group, the disease-free survival was also improved with a hazard ratio of 0.49, translating to a 51% reduction in the risk of recurrence.  So, these findings underscore the prognostic value of ctDNA and suggest that durvalumab provides clinical benefit irrespective of molecular residual disease status. So, the data also supports that ctDNA is a promising biomarker for future personalized strategies in the perioperative treatment of muscle-invasive bladder cancer. Dr. Neeraj Agarwal: Thank you, Jeanny. It is great to see that durvalumab is improving outcomes in these patients regardless of ctDNA status. However, based on these data, presence of ctDNA in our patients warrants a closer follow-up with imaging studies, because these patients with positive ctDNA seem to have a higher risk of recurrence. Dr. Jeanny Aragon-Ching: I agree, Neeraj.  Let's round out the bladder cancer discussion with Abstract 4518, which reported the interim results of SURE-02, which is a phase 2 study evaluating neoadjuvant sacituzumab govitecan plus pembrolizumab in cisplatin-ineligible muscle-invasive bladder cancer. Can you tell us more about this abstract, Neeraj? Dr. Neeraj Agarwal: Sure, Jeanny. So, Dr Andrea Necchi presented interim results from the SURE-02 trial. This is a phase 2 study evaluating neoadjuvant sacituzumab govitecan plus pembrolizumab, followed by a response-adapted bladder-sparing treatment and adjuvant pembrolizumab in patients with muscle-invasive bladder cancer.  So, in this interim analysis, 40 patients were treated and 31 patients were evaluable for efficacy. So, the clinical complete response rate was 38.7%. All patients achieving clinical complete response underwent bladder-sparing approach with a repeat TURBT instead of radical cystectomy. Additionally, 51.6% of patients achieved excellent pathologic response with a T stage of 1 or less after neoadjuvant therapy. The treatment was well tolerated, with only 12.9% of patients experiencing grade 3 or higher adverse events without needing dose reduction of sacituzumab. Molecular profiling, interestingly, showed that clinical complete response correlated with luminal and genomically unstable subtypes, while high stromal gene expression was associated with lack of response.  These results suggest that sacituzumab plus pembrolizumab combination has promising activity in this setting, and tolerability, and along with other factors may potentially allow a bladder preservation approach in a substantial number of patients down the line. Dr. Jeanny Aragon-Ching: Yeah, agree with you, Neeraj. And the findings are very provocative and support completing the full trial enrollment and further exploration of this strategy in muscle-invasive bladder cancer in order to improve and provide further bladder-sparing strategies. Dr. Neeraj Agarwal: Agree. So, let's now turn to the kidney cancer, starting with Abstract 4505, the final overall analysis from CheckMate-214 trial, which evaluated nivolumab plus ipilimumab, so dual checkpoint inhibition strategy, versus sunitinib in our patients with metastatic clear cell renal cell carcinoma. Dr. Jeanny Aragon-Ching: Yeah, absolutely, Neeraj. So, the final 9-year analysis of the phase 3 CheckMate-214 trial confirms the long-term superiority of nivolumab and ipilimumab over sunitinib for first-line treatment of advanced metastatic renal cell carcinoma. So, this has a median follow-up of 9 years. Overall survival remains significantly improved with the combination. So, in the ITT patient population, the intention-to-treat, the hazard ratio for overall survival was 0.71. So, this translates to a 29% reduction in the risk of death. 31% of patients were alive at this 108-month follow-up compared to 20% only in those who got sunitinib. So, similar benefits were observed in the intermediate- and poor-risk groups with a hazard ratio of 0.69, and 30% versus 19% survival at 108 months.  Importantly, a delayed benefit was also seen in those favorable-risk patients. So, the hazard ratio for overall survival improved from 1.45 in the initial report and now at 0.8 at 9 years follow-up, with 35% of patients alive at 108 months compared to 22% in those who got sunitinib. Progression-free survival also favored the nivo-ipi arm across all risk groups. At 96 months, the probability of remaining progression-free was about 23% compared to 9% in the sunitinib arm in the ITT patient population, 25% versus 9% in the intermediate- and poor-risk patients, and 13% compared to 11% in the favorable-risk patients. Importantly, at 96 months, 48% of patients in the nivo-ipi responders remained in response compared to just 19% in those who got sunitinib. And in the favorable-risk group, 36% of patients who responded remained in response, although data were not available for sunitinib in this subgroup.  So, this data reinforces the use of nivolumab and ipilimumab as a durable and effective first-line effective strategy for standard of care across all risk groups for advanced renal cell carcinoma. Dr. Neeraj Agarwal: Thank you, Jeanny. And of course, since ipi-nivo data were presented, several other novel ICI-TKI combinations have emerged. And I'm really hoping to see very similar data with TKI-ICI combinations down the line. It is really important to note that we are not seeing any new safety signals with the ICI combinations or ICI-based therapies, which is very reassuring given the extended exposure. Dr. Jeanny Aragon-Ching: Absolutely agree with you there, Neeraj.  Now, going on and moving on to Abstract 4514, which is the KEYNOTE-564 trial, and they reported on the 5-year outcomes of adjuvant pembrolizumab in clear cell RCC in patients who are at high risk for recurrence. Can you tell us a little bit more about this abstract, Neeraj? Dr. Neeraj Agarwal: Sure. So, the KEYNOTE-564 trial established pembrolizumab monotherapy as the first adjuvant regimen to significantly improve both disease-free survival and overall survival compared to placebo after surgery for patients with clear cell renal cell carcinoma. So, Dr Naomi Haas presented the 5-year update from this landmark trial.  A total of 994 patients were randomized to receive either pembrolizumab or placebo. The median follow-up at the time of this analysis was approximately 70 months. Disease-free survival remained significantly improved with pembrolizumab. The median DFS was not reached with pembrolizumab compared to 68.3 months with placebo, with a hazard ratio of 0.71, translating to a 29% reduction in risk of recurrence. At 5 years, 60.9% of patients receiving pembrolizumab remained disease-free compared to 52.2% with placebo. Overall survival also favored pembrolizumab. The hazard ratio for OS was 0.66, translating to a 34% reduction in risk of death, with an estimated 5-year overall survival rate of 87.7% with pembrolizumab compared to 82.3% for placebo. Importantly, these benefits were consistent across all key subgroups, including patients with sarcomatoid features. In addition, no new serious treatment-related adverse events have been reported in the 3 years since treatment completion.  So, these long-term data confirm pembrolizumab as a durable and effective standard adjuvant therapy for patients with resected, high-risk clear cell renal cell carcinoma. Dr. Jeanny Aragon-Ching: Thank you for that wonderful summary, Neeraj. Dr. Neeraj Agarwal: That wraps up our kidney cancer highlights. Any closing thoughts, Jeanny, before we conclude? Dr. Jeanny Aragon-Ching: It's been so wonderful reviewing these abstracts with you, Neeraj. So, the 2025 ASCO Annual Meeting showcased a lot of transformative data across GU cancers, from first-in-class bispecifics to long-term survival in RCC. And these findings are already shaping our clinical practices. Dr. Neeraj Agarwal: I agree. And we have covered a broad spectrum of innovations in GU cancers with strong clinical relevance.  So, thank you, Jeanny, for joining me today and sharing your insights.  And thank you to our listeners for joining us.

Dr. Vamsi Velcheti and Dr. Nate Pennell discuss novel treatment approaches in small cell and non-small cell lung cancer that were featured at the 2025 ASCO Annual Meeting. TRANSCRIPT Dr. Vamsi Velcheti: Hello, I'm Dr. Vamsi Velcheti, your guest host of the ASCO Daily News Podcast. I'm a professor of medicine and chief of hematology and oncology at the Mayo Clinic in Jacksonville, Florida. The 2025 ASCO Annual Meeting featured some exciting advancements in small cell lung cancer, targeted therapies for non-small cell lung cancer, and other novel [treatment] approaches. Today, I'm delighted to be joined by Dr. Nate Pennell to discuss some of the key abstracts that are advancing the lung cancer field. Dr. Pennell is the co-director of the Cleveland Clinic Lung Cancer Program and also the vice chair of clinical research at the Taussig Cancer Institute. Our full disclosures are available in the transcript of this episode. Nate, it's great to have you back on the podcast. Thanks so much for being here. Dr. Nate Pennell: Thanks, Vamsi. Always a pleasure. Dr. Vamsi Velcheti: Let's get started, and I think the first abstract that really caught my attention was Abstract 8516, “The Randomized Trial of Relevance of Time of Day of Immunotherapy for Progression-Free and Overall Survival in Patients With Non-Small Cell Lung Cancer.” What are your thoughts about this, Nate? Dr. Nate Pennell: I agree. I thought this was one of the most discussed abstracts, certainly in the lung cancer session, but I think even outside of lung cancer, it got some discussion. So, just to put this in perspective, there have been a number of publications that have all been remarkably consistent, and not just in lung cancer but across multiple cancer types, that immunotherapy, immune checkpoint inhibitors, are commonly used. And all of them have suggested, when looking at retrospective cohorts, that patients who receive immune checkpoint inhibitors earlier in the day – so in the morning or before the early afternoon – for whatever reason, appear to have better outcomes than those who get it later in the day, and this has been repeated. And I think many people just sort of assumed that this was some sort of strange association and that there was something fundamentally different from a prognostic standpoint in people who came in in the morning to get their treatment versus those who came later in the afternoon, and that was probably the explanation. The authors of this randomized trial actually decided to test this concept. And so, about 210 patients with previously untreated advanced non-small cell lung cancer were randomly assigned to get chemo and immune checkpoint inhibitor – either pembrolizumab or sintilimab – and half of them were randomly assigned to get the treatment before 3 PM in the afternoon, and half of them were assigned to get it after 3 PM in the afternoon. And it almost completely recapitulated what was seen in the retrospective cohorts. So, the median progression-free survival in those who got earlier treatment was 13.2 months versus only 6.5 months in those who got it later in the day. So, really enormous difference with a hazard ratio of 0.43, which was statistically significant. And perhaps even more striking, the median overall survival was not reached in the early group versus 17.8 months in the late group with a hazard ratio of 0.43, also highly statistically significant. Even the response rate was 20% higher in the early patients; 75% response rate compared to 56% in the late-time-of-day patients. So very consistent across all measures of efficacy with pretty good matched characteristics across the different groups. And so, I have to tell you, I don't know what to make of this. I certainly was a skeptic about the retrospective series, but now we have a prospective randomized trial that shows essentially the same thing. So, maybe there is a difference between getting treated in the morning, although I have yet to hear someone give a very good mechanistic explanation as to why this would be. What were your thoughts on this? Dr. Vamsi Velcheti: It's indeed fascinating, Nate, and I actually think this was a very interesting abstract. Really, I was caught off guard looking at the data. I mean, if it were a drug, we would be so excited, right? I mean, with those kind of survival benefits. I don't know. I think circadian rhythm probably has something to do with it, like different cytokine profiles at the time of administration. I mean, who knows? But I think it's a randomized trial, and I think I would expect to see a mad rush for treatment appointments early in the morning given this, and at least I want my patients to come in first thing in the morning. It'll be interesting to see. Dr. Nate Pennell: It's important to point out that in this study, everyone got chemo and immunotherapy. And, at least in our cancer center, most patients who are getting platinum-doublet chemotherapy and immunotherapy actually do get treated earlier in the day already, just because of the length of the infusion appointment that's needed. So it really is oftentimes people getting single-agent immunotherapy who are often getting the later, shorter visits. But if you have a choice, I think it would be very reasonable to have people treated earlier in the day. And I do think most of the impressions that I got from people about this is that they would like to see it reproduced but certainly well worth further investigation. And I personally would like to see more investigation into what the rationale would be for this because I still can't quite figure out, yes, if you got it at, say, you know, 5 PM, that's later in the day and I can understand that maybe your immune system is somewhat less receptive at that point than it would be in the morning. But because these checkpoint inhibitors have such long half-lives, it's still in your system the next morning when your immune system is supposedly more receptive. So I don't quite understand why that would be the case. Well, let's move on to the next study. I would like to hear your thoughts on Abstract 8515, “Plasma-Guided, Adaptive First-Line Chemoimmunotherapy for Non-Small Cell Lung Cancer.” Dr. Vamsi Velcheti: Yeah, this was another abstract that seems to be really interesting in my opinion. I think there's kind of a lot of emphasis lately on ctDNA and MRD-based assays to monitor disease. In the lung cancer space, we haven't had a lot of clinical trials looking at this prospectively, and this was one of those pilot studies where they looked at circulating free DNA (cfDNA)-based response-adaptive strategy for frontline patients who are PD-L1 positive. So, patients started with pembrolizumab monotherapy, and based on plasma molecular response after 2 cycles, those patients without response received early treatment intensification with a platinum doublet. So the approach essentially was to reduce the chemotherapy exposure in patients who respond to immunotherapy. And only about 17.5% of the patients on the trial received chemotherapy based on lack of molecular response. So, in this trial, what they found was patients with the cfDNA response had a markedly improved PFS of 16.4 months versus 4.8 months. So essentially, like, this is a really nice study to set a foundation on which we have to do larger studies to incorporate molecular markers trying to look at cfDNA response to inform treatment strategy, either escalation or de-escalation strategies. So, I thought it was a very interesting study. Dr. Nate Pennell: Yeah. I mean, we always have this question for patients, “Should they get immunotherapy alone or combined with chemo?” and I think this certainly is intriguing, suggesting that there may be ways you can monitor people and perhaps rescue those that aren't going to respond to single agent. I'd like to see a randomized trial against, you know, this strategy, perhaps against everyone getting, say, chemoimmunotherapy or make sure that you're not potentially harming people by doing this strategy. But I agree, it's time to move beyond just observing that cell-free DNA is prognostic and important and start using it to actually guide treatment. Dr. Vamsi Velcheti: Yeah, and I would just caution though, like, you know, I think we need more data, but, however, it's certainly a very interesting piece of data to kind of help inform future trials. So, there was another abstract that caught my attention, and I think this would be a very interesting abstract in the EGFR space. Abstract 8506, "Patritumab Deruxtecan (HER3-DXd) in Resistant EGFR-Mutant Advanced Non-Small Cell Lung Cancer Patients After Third-Generation EGFR TKI," it's the HERTHENA-Lung02 study. What do you think about the results of this study? Dr. Nate Pennell: Yeah, this was, I would say, very widely anticipated and ultimately a little disappointing, despite being a positive trial. So, these are patients with EGFR-mutant non-small cell lung cancer who have progressed after a third-generation EGFR TKI like osimertinib. This is really an area of major unmet need. We do have drugs like amivantamab in this space, but still definitely an area where essentially patients move from having a highly effective oral therapy to being in the realm of chemotherapy as their best option. So, this HER3 antibody-drug conjugate, patritumab deruxtecan, had some good single-arm data for this. And we're sort of hoping this would become an available option for patients. This trial was designed against platinum-doublet chemotherapy in this setting and with a primary endpoint of progression-free survival. And it actually was positive for improved progression-free survival compared to chemo with a hazard ratio of 0.77. But when you look at the medians, you can see that the median PFS was only 5.8 versus 5.4 months. It was really a modest difference between the two arms. And on the interim analysis, it appeared that there will not be a difference in overall survival between the two arms. In fact, the hazard ratio at the interim analysis was 0.98 for the two arms. So based on this, unfortunately, the company that developed the HER3-DXd has withdrawn their application to the FDA for approval of the drug, anticipating that they probably wouldn't get past approval without that overall survival endpoint. So, unfortunately, probably not, at least for the near future, going to be a new option for these patients. Dr. Vamsi Velcheti: Yeah, I think this is a space that's clearly an unmet need, and this was a big disappointment, I should say. I think all of us were going into the meeting anticipating some change in the standard of care here. Dr. Nate Pennell: Yeah, I agree. It was something that I was telling patients, honestly, that I was expecting this to be coming, and so now, definitely a bit of a disappointment. But it happens and, hopefully, it will still find perhaps a role or other drugs with a similar target. Certainly an active area. Well, let's leave the EGFR-mutant space and move into small cell. There were a couple of very impactful studies. And one of them was Abstract 8006, “Lurbinectedin Plus Atezolizumab as First-Line Maintenance Treatment in Patients With Extensive-Stage Small Cell Lung Cancer, Primary Results from the Phase III IMforte Trial.” So, what was your impression of this? Dr. Vamsi Velcheti: Yeah, I think this is definitely an interesting study, and small cell, I remember those days when we had barely any studies of small cell at ASCO, and now we have a lot of exciting developments in the small cell space. It's really good to see. The IMforte trial is essentially like a maintenance lurbinectedin trial with atezolizumab maintenance. And the study was a positive trial. The primary endpoint was a PFS, and the study showed improvement in both PFS and OS with the addition of lurbinectedin to atezolizumab maintenance. And definitely, it's a positive trial, met its primary endpoint, but I always am a little skeptical of adding maintenance cytotoxic therapies here in this setting. In my practice, and I'd like to hear your opinion, Nate, most patients with small cell after 4 cycles of a platinum doublet, they're kind of really beaten up. Adding more cytotoxic therapy in the maintenance space is going to be tough, I think, for a lot of patients. But also, most importantly, I think this rapidly evolving landscape for patients with small cell lung cancer with multiple new, exciting agents, actually like some FDA-approved like tarlatamab, also like a lot of these emerging therapeutics like I-DXd and other ADCs in this space. You kind of wonder, is it really optimal strategy to bring on like another cytotoxic agent right after induction chemotherapy, or do you kind of delay that? Or maybe have like a different strategy in terms of maintenance. I know that the tarlatamab maintenance trial is probably going to read out at some point too. I think it's a little challenging. The hazard ratio is also 0.73. As I said, it's a positive trial, but it's just incremental benefit of adding lurbi. And also on the trial, we need to also pay attention to the post-progression second-line treatments, number of patients who received tarlatamab or any other investigational agents.  So I think it's a lot of questions still. I'm not quite sure I'd be able to embrace this completely. I think a vast majority of my patients might not be eligible anyway for cytotoxic chemotherapy maintenance right away, but yeah, it's tough. Dr. Nate Pennell: Yeah. I would call this a single and not a home run. It definitely is real. It was a real overall survival benefit. Certainly not surprising that a maintenance therapy would improve progression-free survival. We've known that for a long time in small cell, but first to really show an overall survival benefit. But I completely agree with you. I mean, many people are not going to want to continue further cytotoxics after 4 cycles of platinum-doublet chemo. So I would say, for those that are young and healthy and fly through chemo without a lot of toxicity, I think certainly something worth mentioning. The problem with small cell, of course, is that so many people get sick so quickly while on that observation period after first-line chemo that they don't make it to second-line treatment. And so, giving everyone maintenance therapy essentially ensures everyone gets that second-line treatment. But they also lose that potentially precious few months where they feel good and normal and are able to be off of treatment. So, I would say this is something where we're really going to have to kind of sit and have that shared decision-making visit with patients and decide what's meaningful to them. Dr. Vamsi Velcheti: Yeah, I agree. The next abstract that was a Late-Breaking Abstract, 8000, “Overall Survival of Neoadjuvant Nivolumab Plus Chemotherapy in Patients With Resectable Non-Small Cell Lung Cancer in CheckMate-816.” This was a highly anticipated read-out of the OS data from 816. What did you make of this abstract? Dr. Nate Pennell: Yeah, I thought this was great. Of course, CheckMate-816 changed practice a number of years ago when it first reported out. So, this was the first of the neoadjuvant or perioperative chemoimmunotherapy studies in resectable non-small cell lung cancer. So, just to review, this was a phase 3 study for patients with what we would now consider stage II or stage IIIA resectable non-small cell lung cancer. And they received three cycles of either chemotherapy or chemotherapy plus nivolumab, and that was it. That was the whole treatment. No adjuvant treatment was given afterwards. They went to resection. And patients who received the chemoimmunotherapy had a much higher pathologic complete response rate and a much better event-free survival. And based on this, this regimen was approved and, I think, at least in the United States, widely adopted.  Now, since the first presentation of CheckMate 816, there have been a number of perioperative studies that have included an adjuvant component of immunotherapy – KEYNOTE-671, the AEGEAN study – and these also have shown improved outcomes. The KEYNOTE study with pembrolizumab also with an overall survival benefit. And I think people forgot a little bit about CheckMate-816. So, this was the 5-year overall survival final analysis. And it did show a statistically and, I think, clinically meaningful difference in overall survival with the 3 cycles of neoadjuvant chemo-nivo compared to chemo with a hazard ratio of 0.72. The 5-year overall survival of 65% in the chemo-IO group versus 55% with the chemo alone. So a meaningful improvement. And interestingly, that hazard ratio of 0.72 is very similar to what was seen in the peri-operative pembro study that included the adjuvant component. So, very much still relevant for people who think that perhaps the value of those neoadjuvant treatments might be really where most of the impact comes from this type of approach. They also gave us an update on those with pathologic complete response, showing really astronomically good outcomes. If you have a pathologic complete response, which was more than a quarter of patients, the long-term survival was just phenomenal. I mean, 95% alive at 5 years if they were in that group and suggesting that in those patients at least, the adjuvant treatment may not be all that important.  So, I think this was an exciting update and still leaves very much the open question about the importance of continuing immunotherapy after surgery after the neoadjuvant component. Dr. Vamsi Velcheti: Yeah, I completely agree, Nate. I think the million-dollar question is: “Is there like a population of patients who don't have complete response but like maybe close to complete response?” So, would you like still consider stopping adjuvant IO? I probably would not be comfortable, but I think sometimes, you know, we all have patients who are like very apprehensive of continuing treatments. So, I think that we really need more studies, especially for those patients who don't achieve a complete CR. I think trying to find strategies for like de-escalation based on MRD or other risk factors. But we need more trials in that space to inform not just de-escalation, but there are some patients who don't respond at all to a neoadjuvant IO. So, there may be an opportunity for escalating adjuvant therapies. So, it is an interesting space to watch out for. Dr. Nate Pennell: No, absolutely. Moving to KRAS-mutant space, so our very common situation in patients with non-small cell lung cancer, we had the results of Abstract 8500, “First-Line Adagrasib With Pembrolizumab in Patients With Advanced or Metastatic KRASG12C-Mutated Non-Small Cell Lung Cancer” from the phase 2 portion of the KRYSTAL-7 study. Why was this an interesting and important study? Dr. Vamsi Velcheti: First of all, there were attempts to kind of combine KRASG12C inhibitors in the past with immune checkpoint inhibitors, notably sotorasib with pembrolizumab. Unfortunately, those trials have led to like a lot of toxicity, with increased especially liver toxicity, which was a major issue. This is a phase 2 study of adagrasib in combination with pembrolizumab, and this is a study in the frontline setting in patients with the G12C-mutant metastatic non-small cell lung cancer. And across all the PD-L1 groups, the ORR was 44%, and the median PFS was 11 months, comparable to the previous data that we have seen with adagrasib in this setting. So it's not like a major improvement in clinical efficacy. However, I think the toxicity profile that we were seeing was slightly better than the previous trials in combination with sotorasib, but you still have a fair amount of transaminitis even in the study. At this point, this is not ready for clinical primetime. I don't think we should be using sotorasib or adagrasib in the frontline or even in the second line in combination with checkpoint inhibitors. Combining these drugs with checkpoint inhibitors in the clinical practice might lead to adverse outcomes. So, we need to wait for more data like newer-generation G12C inhibitors which are also being studied in combination, so we'll have to kind of wait for more data to emerge in this space. Dr. Nate Pennell: I agree, this is not immediately practice changing. This is really an attempt to try to combine targeted treatment with immune checkpoint inhibitor. And I agree with you that, you know, it does appear to be perhaps a little bit better tolerated than some of the prior combinations that have tried in this space. The outcomes overall were not that impressive, although in the PD-L1 greater than 50%, it did have a better response rate perhaps than you would expect with either drug alone. And I do think that the company is focusing on that population for a future randomized trial, which certainly would inform this question better. But in the meantime, I agree with you, there's a lot of newer drugs that are coming along that potentially may be more active and better tolerated. And so, I'd say for now, interesting but we'll wait and see. Dr. Vamsi Velcheti: Yeah, so now moving back again to small cell. So, there was a Late-Breaking Abstract, 8008. This is a study of tarlatamab versus chemotherapy as second-line treatment for small cell lung cancer. They presented the primary analysis of the phase III DeLLphi-304 study. What do you think about this? Dr. Nate Pennell: Yeah, I thought this was really exciting. This was, I would say, perhaps the most important lung study that was presented. Tarlatamab is, of course, the anti-DLL3 bispecific T-cell engager compound, which is already FDA approved based on a prior single-arm phase II study, which showed a very nice response rate as a single agent in previously treated small cell lung cancer and relatively manageable side effects, although somewhat unique to solid tumor docs in the use of these bispecific drugs in things like cytokine release syndrome and ICANS, the neurologic toxicities. So, this trial was important because tarlatamab was approved, but there were also other chemotherapy drugs approved in the previously treated space. And so, this was a head-to-head second-line competition comparison between tarlatamab and either topotecan, lurbinectedin, or amrubicin in previously treated small cell patients with a primary endpoint of overall survival. So, a very well-designed trial. And it did show, I think, a very impressive improvement in overall survival with a median overall survival in the tarlatamab group of 13.6 months compared to 8.3 months with chemotherapy, hazard ratio of 0.6. And progression-free survival was also longer at 4.2 months versus 3.2 months, hazard ratio of 0.72. In addition to showing improvements in cancer-related symptoms that were improved in tarlatamab compared to chemotherapy, there was actually also significantly lower rates of serious treatment-related adverse events with tarlatamab compared to chemotherapy. So, you do still see the cytokine release syndrome, which is seen in most people but is manageable because these patients are admitted to the hospital for the first two cycles, as well as a significant number of patients with neurologic side effects, the so-called ICANS, which also can be treated with steroids. And so, I think based upon the very significant improvement in outcomes, I would expect that this should become our kind of standard second-line treatment since it seems to be much better than chemo. However, tarlatamab is definitely a new drug that a lot of places are not used to using, and I think a lot of cancer centers, especially ones that aren't tied to a hospital, may have questions about how to deal with the CRS. So, I'm curious your thoughts on that. Dr. Vamsi Velcheti: Yeah, thank you, Nate. And I completely agree. I think the data looked really promising, and I've already been using tarlatamab in the second-line space. The durability of response and overall, having used tarlatamab quite a bit - like, I participated in some of the early trials and also used it as standard of care - tarlatamab has unique challenges in terms of like need for hospitalization for monitoring for the first few treatments and make sure, you know, we monitor those patients for CRS and ICANS. But once you get past that initial administration and monitoring of CRS, these patients have a much better quality of life, they're off chemotherapy, and I think it's really about the logistics of actually administering tarlatamab and coordination with the hospital and administration in the outpatient setting. It's definitely challenging, but I think it definitely can be done and should be done given what we are seeing in terms of clinical efficacy here. Dr. Nate Pennell: I agree. I think hospital systems now are just going to have to find a way to be able to get this on formulary and use it because it clearly seems to be more effective and generally better tolerated by patients. So, should move forward, I think. Finally, there's an abstract I wanted to ask you about, Abstract 8001, which is the “Neoadjuvant osimertinib with or without chemotherapy versus chemotherapy alone in resectable epidermal growth factor receptor-mutated non-small cell lung cancer: The NeoADAURA Study”. And this is one that I think was also fairly highly anticipated. So, what are your thoughts? Dr. Vamsi Velcheti: You know, I wasn't probably surprised with the results, and I believe we were all expecting a positive trial, and we certainly were handed a positive trial here. It's a phase III trial of osimertinib and chemotherapy or osimertinib in the neoadjuvant space followed by surgery, followed by osimertinib. It's a global phase 3 trial and very well conducted, and patients with stage II to stage IIIB were enrolled in the study. And in the trial, patients who had a neoadjuvant osimertinib with or without chemotherapy showed a significant improvement in major pathologic response rates over chemotherapy alone. And the EFS was also positive for osimertinib and chemotherapy, osimertinib monotherapy as well compared to chemotherapy alone. So overall, the study met its primary endpoint, and I think it sheds light on how we manage our patients with early-stage lung cancer. I think osimertinib, we know that osimertinib is already FDA approved in the adjuvant space, but what we didn't really know is how was osimertinib going to work in the neoadjuvant space. And there are always situations, especially for stage III patients, where we are on the fence about, are these patients already close to being metastatic? They have, like, almost all these patients have micrometastatic disease, even if they have stage III. As we saw in the LAURA data, when you look at the control arm, it was like a very short PFS. Chemoradiation does nothing for those patients, and I think these patients have systemic mets, either gross or micrometastatic disease at onset. So, it's really important to incorporate osimertinib early in the treatment course. And I think, especially for the locally advanced patients, I think it's even more important to kind of incorporate osimertinib in the neoadjuvant space and get effective local control with surgery and treat them with adjuvant. I'm curious to hear your thoughts, Nate. Dr. Nate Pennell: I am a believer and have long been a believer in targeted adjuvant treatments, and, you know, it has always bothered me somewhat that we're using our far and away most effective systemic therapy; we wait until after they go through all their pre-op treatments, they go through surgery, then they go through chemotherapy, and then finally months later, they get their osimertinib, and it still clearly improves survival in the adjuvant setting. Why not just start the osimertinib as soon as you know that the patient has EGFR-mutant non-small cell lung cancer, and then you can move on to surgery and adjuvant treatment afterwards? And I think what was remarkable about this study is that all of these patients almost - 90% in each arm - went to surgery. So, you weren't harming them with the neoadjuvant treatment. And clearly better major pathologic response, nodal downstaging, event-free survival was better. But I don't know that this trial is ever going to show an overall survival difference between neoadjuvant versus just surgery and adjuvant treatment, given how effective the drug is in the adjuvant setting. Nonetheless, I think the data is compelling enough to consider this, certainly for our N2-positive, stage IIIA patients or a IIIB who might be otherwise surgical candidates. I think based on this, I would certainly consider that. Dr. Vamsi Velcheti: Yeah, and especially for EGFR, like even for stage IIIB patients, in the light of the LAURA study, those patients who do not do too well with chemoradiation. So you're kind of delaying effective systemic therapy, as you said, waiting for the chemoradiation to finish. So I think probably time to revisit how we kind of manage these locally advanced EGFR patients. Dr. Nate Pennell: Yep, I agree.
