The FDA approved lenacapavir, a twice-yearly injectable PrEP shown to be 99% effective in preventing HIV, though high cost may limit global access. A phase 3 trial found that adding pembrolizumab to standard care improved event-free survival in head and neck cancer, especially in patients with high PD-L1 expression. MASLD-related deaths in the U.S. have quadrupled since 2006, rising most sharply in older adults and rural areas, and are expected to continue increasing.
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.

Dr. Shaalan Beg and Dr. Kristen Ciombor discuss practice-changing studies in GI cancers and other novel treatment approaches that were presented at the 2025 ASCO Annual Meeting. Transcript Dr. Shaalan Beg: Hello, I'm Dr. Shaalan Beg, welcoming you to the ASCO Daily News Podcast. I'm a medical oncologist and an adjunct associate professor at UT Southwestern Medical Center in Dallas, Texas. There were some remarkable advances in gastrointestinal cancers that were presented at the 2025 ASCO Annual Meeting, and I'm delighted to be joined by Dr. Kristen Ciombor to discuss some exciting GI data. Dr. Ciombor is the Ingram Associate Professor of Cancer Research and a co-leader of Translational Research and the Interventional Oncology Research Program at the Vanderbilt Ingram Cancer Center. Our full disclosures are available in the transcript of this episode. Dr. Ciombor, it's great to have you on the podcast today. Dr. Kristen Ciombor: Thanks, Dr Beg. It's great to be here. Dr. Shaalan Beg: Alright, let's kick it off. Big year for GI cancers. We'll start off with LBA1. This was the ATOMIC study sponsored by NCI and the National Clinical Trials Network (NCTN) and the Alliance group. This is a randomized study of standard chemotherapy alone or combined with atezolizumab as adjuvant therapy for stage III mismatch repair deficient colorectal cancer. Dr. Kristen Ciombor: I think this study was really definitely practice-changing, as you can tell because it was a Plenary. But I do have some concerns in terms of how we're actually going to implement this and whether this is the final answer in this disease subtype. So, as you said, the patients were enrolled with stage III resected mismatch repair deficient colon cancer, and then they were randomized to either modified FOLFOX6 with or without atezolizumab. And that's where it starts to become interesting because not many of us give FOLFOX for 6 months like was done in this study. Obviously, the study was done over many years, so that was part of that answer, but also the patients received atezolizumab for a total of 12 months. So the question, I think, that comes from this abstract is, is this practical and is this the final answer? I do think that this is practice-changing, and I will be talking to my patients with resected mismatch repair deficient colon cancer about FOLFOX plus atezolizumab. I think the big question is, do these patients need chemotherapy? And can we do a neoadjuvant approach instead? And that's where we don't have all the answers yet. Dr. Shaalan Beg: Yeah, but it has been great to see immunotherapy make its way into the adjuvant space after having made such a big impact in the metastatic space, but still some unanswered questions in terms of the need for chemotherapy and then the duration of therapy, which I guess we'll have to stay tuned in for the next couple of years to to get a lot of those questions answered. Dr. Kristen Ciombor: Yeah, but a big congratulations to the study team, to the NCTN, the NCI. I mean, this is really a great example of federally funded research that needs to continue. So, great job by the study team. The DFS 10% difference is really very large and certainly a practice-changing study. Dr. Shaalan Beg: Yeah, and and sticking with colon cancer, and and this another federally funded study, but this time funded by a Canadian cancer clinical trials group was LBA3510. This is the CHALLENGE study. It's a randomized phase 3 trial of the impact of a structured exercise program on disease-free survival for stage III or high-risk stage II colon cancer. This study got a lot of buzz, a lot of mainstream press coverage, and a lot of discussions on what that means for us for the patients who we're going to be seeing next week in our clinic. What was your takeaway? Dr. Kristen Ciombor: Yeah, this is a really interesting study, and I was so glad to see it presented because this partially answers one of the questions that patients always have for us in clinic, right? You know, once they've completed their standard chemotherapy and surgery, what else can they do to help prevent recurrence? And so we've always known and sort of extrapolated that healthy lifestyle habits are good, but now we have data, particularly in these patients. Most of them were stage III colon cancer patients, those had high-risk stage II cancer. And basically, the goal was to increase their physical activity by at least 10 MET hours per week. So, my big question, of course, as I came into this presentation was, “Okay, what does that mean exactly? How does that translate to real life?” And really what the author presented and explained was that basically most patients could hit their target by adding a 45- to 60-minute brisk walk 3 to 4 times a week. So I think this is very approachable. Now, in the confines of the study, this was a structured exercise program, so it wasn't just patients doing this on their own. But I do think kind of extrapolating from that, that this is very achievable for most patients. And not only did this prevent recurrence of their prior cancer, but actually the rate of new primary cancer diagnoses, was less, which is really interesting, especially in the breast and prostate cancer. So this was a really interesting, and I think practice-changing study as well, especially given that this is something that most patients can do. Dr. Shaalan Beg: Yeah, and there was a lot of discussion in the hallways after the presentation in terms of how this really changes our existing practice because most folks already recommend exercise as a way for improving outcomes in cancer patients. So we've already been doing that. Now we have some data on how much it can impact the benefit. But there was some discussion about what the actual degree of impact was. There was a drop-off rate in terms of how long folks were able to stick with this exercise regimen. But you've seen this in clinic when someone have their surgery, they have their chemotherapy, they've been so intimately involved with the oncology world, with the oncology practice, and they somehow feel that they're being let loose into this mean, angry world without any guidance and they're looking for something to do. “What more can I do in terms of my lifestyle?” And then here we have very solid data, as solid as can be for an intervention like exercise, showing that there is an impact and you can give a prescription for exercise when someone wraps up their chemotherapy for colon cancer, thanks to the study. Dr. Kristen Ciombor: Yeah. It was a great study. Dr. Shaalan Beg: Moving to gastroesophageal cancer, another late-breaking abstract. This is LBA5. The MATTERHORN trial was a phase 3 trial of durvalumab plus FLOT for resectable GE junction and gastric cancer. And again, another area where immunotherapy has made an impact, and here we're seeing it move closer for earlier-stage disease. What was your take-home for the MATTERHORN trial? Dr. Kristen Ciombor: Yeah, so this study looked at neoadjuvant perioperative durvalumab plus our current standard chemotherapy of FLOT versus placebo plus FLOT. And this was a large study, almost 1,000 patients were randomized. And the primary endpoint was event-free survival, and it was definitely met in favor of the D + FLOT arm, as Dr. Klempner discussed after Dr Janjigian's presentation. I do think there are still some unanswered questions here. Overall survival is not yet mature, so we do have to wait and see how that shakes out. But it's very interesting and kind of is reflective of what, as you said, we're looking at earlier and earlier lines of therapy, particularly with immunotherapy, in these GI cancer spaces. So it makes a lot of sense to test this and and to look at this. So the toxicity was pretty similar to what we would expect. Primary endpoint was met, but again, we'll have to wait and see what the survival data looks like. Dr. Shaalan Beg: Yeah, and in oncology, we know, especially for treatment that does add additional cost, it does add additional potential toxicity that we want to see that overall survival nudged. I did see some polls on social media asking folks whether their practices changed from this, and I think the results were favoring adding durvalumab for this group of patients but understanding that there are caveats to the addition of treatments and the eventual FDA approval in that indication as well. Dr. Kristen Ciombor: Exactly. I completely agree with that. Dr. Shaalan Beg: All right. How about we stick with gastroesophageal cancer? LBA4002 was trastuzumab deruxtecan versus ramucirumab plus paclitaxel for second-line treatment in HER2-positive unresectable or metastatic gastric cancer or GE junction cancer. This was the DESTINY-Gastric04 study. And again, antibody-drug conjugates making a big impact across different diseases. And here we have more data in the HER2-positive gastric cancer space. Your thoughts on this study? Dr. Kristen Ciombor: Yeah, so this is a really important space in gastroesophageal cancer because the HER2 positivity rate is fairly high as compared to some of our other tumor types. So, I do think one of the important things was that patients did have biopsy confirmation of HER2 status, which was very important, and then they were randomized to either T-DXd versus the kind of second-line standard of ramucirumab-paclitaxel. So this was a great practical study and really answers a question that we had for a while in terms of does anti-HER2 therapy in the second-line really impact and improve survival. So we did see a statistically significant improvement favoring T-DXd. I do think it's always important to look at toxicity, though, too. And there was about almost 14% rate of interstitial lung disease, which of course is the most feared toxicity from some of these antibody-drug conjugates, especially T-DXd. So I do think it's important to keep that in mind, but this is definitely a great addition to the armamentarium for these HER2-positive patients. Dr. Shaalan Beg: And pancreas cancer was on the stage after a very long time with a positive clinical trial. This is Abstract 4006. These were preliminary results from a phase 2 study of elraglusib in combination with gemcitabine/nab-paclitaxel versus gemcitabine/nab-paclitaxel alone for previously untreated metastatic pancreas cancer. This is a frontline clinical trial of gemcitabine/nab-paclitaxel plus/minus the study drug. There were other cohorts in this study as well, but they reported the results of their part 3B arm. And great to see some activity in the pancreas space. And your thoughts? Dr. Kristen Ciombor: Yeah, we definitely need better treatments in pancreas cancer. This was a very welcome presentation to see. The elraglusib is an inhibitor of GSK-3beta, and it's thought that that mediates drug resistance and EMT. And so this is, I think, a perfect setting to test this drug. So patients basically were randomized. Patients with metastatic pancreas cancer were randomized 2: 1 to gemcitabine/nab-paclitaxel plus or minus this elraglusib. So, what we saw was that overall survival was better with the addition of this new drug. And overall, not only the 1-year overall survival, but also median overall survival. The thing that was interesting, though, was that we saw that the overall survival rates were 9.3 months with the combination versus 7.2 months with just gemcitabine/nab-paclitaxel. And that's a little bit lower than we've seen in other studies. So, not sure what was going on there. Was it the patients that were a bit sicker? Was it a patient selection, you know, thing? I'm not really sure how to explain that so much. Also, the toxicity profile was much higher in terms of visual impairment, with over 60% of patients being treated with the combination versus 9% with gemcitabine/nab-paclitaxel. So these were mild, grade 1 and 2, but still something to be cautious about. Dr. Shaalan Beg: And especially with this being a phase 2 trial, making sure that in a larger study we're able to better evaluate the toxicity and see if the control arm in the larger confirmatory study performs differently will be really important before this compound makes it to the clinic in our space. But very exciting to see these kinds of results for pancreas adenocarcinoma. Dr. Kristen Ciombor: Yeah. Dr. Shaalan Beg: We've talked, it seems, a couple of times on this podcast about the BREAKWATER clinical trial. We did hear PFS and updated OS data, updated overall survival data on first-line encorafenib plus cetuximab plus modified FOLFOX6 for BRAF-mutated colorectal cancer. This was LBA3500. And eagerly anticipated results – we have all previously heard the progression-free survival results – but here we heard updated overall survival results, and very well-received study it seemed from the audience that time. So what are your takeaways on the updated results for BREAKWATER? Dr. Kristen Ciombor: In my opinion, this was one of the most practice-confirming studies. As you mentioned, we've already seen some of the preliminary data of BREAKWATER at prior meetings. But really what was particularly impactful for me was the median overall survival with the BREAKWATER regimen. So, again, patients received FOLFOX, encorafenib cetuximab in the first line if they had BRAF-mutated V600E-mutated colorectal cancer. And the median PFS was 12.8 months, which was actually really remarkable in this traditionally very aggressive, poor prognosis subtype of tumors. So, by seeing a median overall survival of 30.3 months was just incredible, in my opinion. Just a few years ago, that was considered the median overall survival for all comers for metastatic colorectal cancer. And we know the median overall survival was more in the less than 12 months range for BRAF. So this was incredibly impactful, and I think should be absolutely practice-changing for anyone who is eligible for this regimen. I think again, where the practice meets the study is what's kind of important to think about too, how long did patients get FOLFOX, and certainly it adds toxicity to add a BRAF-targeted regimen on top of FOLFOX already. So, one of the other interesting things about the study, though, was that even though it didn't complete treatment, they actually did look at encorafenib/cetuximab alone and in the first line without chemotherapy. And those preliminary results actually looked okay, especially for patients who might not be able to tolerate chemotherapy, which we certainly see in practice. So, overall, definitely more data. And I agree that it's certainly practice-changing. Dr. Shaalan Beg: And it completely, as you mentioned, changes the outlook for a person who's diagnosed with BRAF-mutated metastatic colon cancer today versus even 7 or 8 years ago. Dr. Kristen Ciombor: And we're seeing this over and over in other subtypes too, but how you choose to treat the patient up front really matters. So really giving the right regimen up front is the key here. Dr. Shaalan Beg: And along the same lines, Abstract 3501 wanted to answer the question on whether people with MSI-high metastatic colorectal cancer need double checkpoint inhibitor therapy or is single therapy enough. So this [CheckMate-8HW] study compared nivo plus ipi with nivo alone, nivo monotherapy for MSI-high metastatic colorectal cancer. And we've known that both of these are fairly active regimens, but we also know the chance of immune-related adverse events is significantly higher with combination therapy. So this was a much-needed study for this group of patients. And what were your takeaways here? Dr. Kristen Ciombor: This, of course, has been really nivo-ipi in the first-line MSI-high metastatic colorectal cancer is now a standard of care. And not everybody is eligible for it, and there could be reasons, toxicity reasons, and other things too. But as we've been seeing for the last couple of years, immunotherapy clearly beats chemo in this space. And now looking at doublet versus single immunotherapy treatment in the first line, I think really nivo-ipi does beat out monotherapy. I will say, however, there is a caveat in that we still haven't seen the nivo-ipi versus nivo in the first line. So what has been presented thus far has been across all lines of therapy, and that does muddy the waters a little bit. So definitely looking forward and and we've asked this many times and based on the statistical plan and and what not, you know, we just haven't seen that data yet. But I do think it's becoming increasingly important to consider doublet immunotherapy for these patients as long as there are no contraindications. With the again, with the caveat that we have to have these toxicity discussions in the clinic with patients because many patients can tolerate it, you know, this regimen fairly well, but there can be very severe toxicities. So, I think an informed discussion should really be had with each patient before moving forward. Dr. Shaalan Beg: Yeah, informed decision, making them aware of the potential of real significant toxicities, immune-related toxicities with double therapy. But I am curious in your practice, how often do you see people choosing doublet therapy as frontline? Dr. Kristen Ciombor: So patients are really savvy, and a lot of times they've heard this data before or have come across it in patient advocacy groups and other things, and it's really nice to be able to have that conversation of the risk versus benefit. So I will say not all of my patients choose doublet, and many of them are still cured with immunotherapy monotherapy. So the big question there is, will we ever understand who actually needs the doublet versus who can still be cured or have very good long-term outcomes with just the single agent? And that has not been answered yet. Dr. Shaalan Beg: What a great point. So the last abstract I was hoping we could talk about is POD1UM-303 or the INTERAACT2 subgroup analysis and impact of delayed retifanlimab treatment for patients with squamous cell carcinoma of the anal canal. What were your thoughts here? Dr. Kristen Ciombor: This was a study, actually we saw at ESMO, we saw the primary data at ESMO last year, and this was an update with some exploratory analyses. But this was really an important study because once again, we're looking at immunotherapy in later lines of therapy. That's how we started looking at and investigating immunotherapy, and now we're moving it up and up in the treatment course. So this was a study of carboplatin/paclitaxel plus or minus retifanlimab. Actually it was retifanlimab versus placebo. And it was a positive study, as we heard last year. This actually led to FDA approval of this regimen last month, just before ASCO, and it has now been incorporated in the NCCN guidelines as the preferred first-line option. So what I thought was important from the additional data presented at ASCO was looking at the different subgroups, it did not appear that patients with liver mets or not had different outcomes. So that was really good to see because sometimes in colon cancer we see that immunotherapy doesn't work as well when patients have liver mets. And interestingly, because we use immunotherapy in anal cancer without any biomarkers, unlike with colon cancer or some of the other tumor types, also the authors looked at PD-L1 status, and it did look like maybe patients did a little bit better if they had higher PD-L1 expression, but patients still could benefit even if they were PD-L1 negative. So that was important, I think, and we will continue to see further data come out from this study. I want to mention also that EA2176 just completed accrual, so that was carbo-taxol plus or minus nivolumab. And so we should be seeing that data sometime soon, which will hopefully also confirm the ongoing role for immunotherapy in the first-line setting for anal cancer.

Dr. Allison Zibelli and Dr. Rebecca Shatsky discuss advances in breast cancer research that were presented at the 2025 ASCO Annual Meeting, including a potential new standard of care for HER2+ breast cancer, the future of ER+ breast cancer management, and innovations in triple negative breast cancer therapy. Transcript Dr. Allison Zibelli: Hello and welcome to the ASCO Daily News Podcast. I'm Dr. Allison Zibelli, your guest host of the podcast today. I'm an associate professor of medicine and a breast medical oncologist at the Sidney Kimmel Comprehensive Cancer Center at Jefferson Health. There was a substantial amount of exciting breast cancer data presented at the 2025 ASCO Annual Meeting, and I'm delighted to be joined by Dr. Rebecca Shatsky today to discuss some of these key advancements. Dr. Shatsky is an associate professor of medicine at UC San Diego and the head of breast medical oncology at the UC San Diego Health Moores Cancer Center, where she also serves as the director of the Breast Cancer Clinical Trials Program and the Inflammatory and Triple-Negative Breast Cancer Program. Our full disclosures are available in the transcript of this episode. Dr. Shatsky, it's great to have you on the podcast today. Dr. Rebecca Shatsky: Thanks, Dr. Zibelli. It's wonderful to be here. Dr. Allison Zibelli: So, we're starting with DESTINY-Breast09, which was trastuzumab deruxtecan and pertuzumab versus our more standard regimen of taxane, trastuzumab pertuzumab for first-line treatment of metastatic HER2-positive breast cancer. Could you tell us a little bit about the study? Dr. Rebecca Shatsky: Yeah, absolutely. So, this was a long-awaited study. When T-DXd, or trastuzumab deruxtecan, really hit the market, a lot of these DESTINY-Breast trials were started around the same time. Now, this was a global, randomized, phase 3 study presented by Dr. Sara Tolaney from the Dana-Farber Cancer Institute of Harvard in Boston. It was assessing essentially T-DXd in the first-line setting for metastatic HER2-positive breast cancer in addition to pertuzumab. And that was randomized against our standard-of-care regimen, which was established over a decade ago by the CLEOPATRA trial, and we've all been using that internationally for at least the past 10 years. So, this was a large trial, and it was one-to-one-to-one of patients getting T-DXd plus pertuzumab, T-DXd alone, or THP, which mostly is used as docetaxel and trastuzumab and pertuzumab every three weeks for six cycles. And this was in over 1,000 patients; it was 1,159 patients with metastatic HER2-positive breast cancer. This was a very interesting trial. It was looking at the use of trastuzumab deruxtecan, but patients were started on this treatment for their first-line metastatic HER2-positive breast cancer with no end date to their T-DXd. So, it was, you know, you were started on T-DXd every 3 weeks until progression. Now, CLEOPATRA is a little bit different than that, though, as we know. So, CLEOPATRA has a taxane plus trastuzumab and pertuzumab. But generally, patients drop the taxane after about six to seven cycles because, as we know, you can't be really on a taxane indefinitely. You get pretty substantial neuropathy as well as cytopenias, other things that end up happening. And so, in general, that regimen has sort of a limited time course for its chemotherapy portion, and the patients maintained after the taxane is dropped on their trastuzumab and their pertuzumab, plus or minus endocrine therapy if the investigator so desires. And the primary endpoint of the trial was progression-free survival by blinded, independent central review (BICR) in the intent-to-treat population. And then it had its other endpoints as overall survival, investigator-assessed progression-free survival, objective response rates, and duration of response, and of course, safety. As far as the results of this trial, so, I think that most of us key opinion leaders in breast oncology were expecting that this was going to be a positive trial. And it surely was. I mean, this is a really, really active drug, especially in HER2-positive disease, of course. So, the DESTINY-Breast03 data really established that, that this is a very effective treatment in HER2-positive metastatic breast cancer. And this trial really, again, showed that. So, there were 383 patients that ended up on the trastuzumab plus deruxtecan plus pertuzumab arm, and 387 got THP, the CLEOPATRA regimen. What was really interesting also to note of this before I go on to the results was that 52% of patients on this trial had de novo metastatic disease. And that's pretty unusual for any kind of metastatic breast cancer trial. It kind of shows you, though, just how aggressive this disease is, that a lot of patients, they present with de novo metastatic disease. It's also reflecting the global nature of this trial where maybe the screening efforts are a little bit less than maybe in the United States, and more patients are presenting as later stage because to have a metastatic breast cancer trial in the United States with 52% de novo metastatic disease doesn't usually happen. But regardless, the disease characteristics were pretty well matched between the two groups. 54% of the patients were triple positive, or you could say hormone-positive because whether they were PR positive or ER positive and PR negative doesn't really matter in this disease. And so, the interim data cutoff was February of this year, of 2025. So, the follow-up so far has been about 29 months, so the data is still really immature, only 38% mature for progression-free survival interim analysis. But what we saw is that T-DXd plus pertuzumab, it really improved progression-free survival. It had a hazard ratio that was pretty phenomenal at 0.56 with a confidence interval that was pretty narrow of 0.44 to 0.71. So, very highly statistically significant data here. The progression-free survival was consistent across all subgroups. Overall survival, very much immature at this time, but of course, the trend is towards an overall survival benefit for the T-DXd group. The median durable response with T-DXd plus pertuzumab exceeded 3 years. Now, importantly, though, I want to stress this, is grade 3 or above treatment-emergent adverse events occurred in both subgroups pretty equally. But there were 2 deaths in the T-DXd group due to interstitial lung disease. And there was a 12.1% adjudicated drug-induced interstitial lung disease/pneumonitis event rate in the T-DXd group and only 1%, and it was grade 1-2, in the THP group. So, that's really the caveat of this therapy, is we know that a percentage of patients are going to get interstitial lung disease, and that some may have very serious adverse events from it. So, that's always something I keep in the back of my mind when I treat patients with T-DXd. And so, overall, the conclusions of the trial were pretty much a slam dunk. T-DXd plus pertuzumab, it had a highly statistically significant and clinically meaningful improvement in progression-free survival versus the CLEOPATRA regimen. And that was across all subgroups for first-line metastatic HER2-positive breast cancer here. And so, yeah, the data was pretty impressive. Just to go into the overall response rate, because that's always super important as well, you had 85.1% of patients having a confirmed overall RECIST response rate in the T-DXd plus pertuzumab group and a 78.6 in the CLEOPATRA group. The complete CR rate, complete response was 15.1% in the T-DXd group and 8.5 in the CLEOPATRA regimen. And it was really an effective regimen in this group, of course. Dr. Allison Zibelli: So, the investigators say at the end of their abstract that this is the new standard of care. Would you agree with that statement? Dr. Rebecca Shatsky: Yeah, that was a bold statement to make because I would say in the United States, not necessarily at the moment because the quality of life here, you have to think really hard about. Because one thing that's really important about the DESTINY-Breast09 data is that this was very much an international trial, and in many of the countries where patients enrolled on this, they were not able to access T-DXd off trial. And so, for them, this means T-DXd now or potentially never. And so, that is a really big difference whereas internationally, that may mean standard of care. However, in the US, patients have no issues accessing T-DXd in the second- or third-line settings. And right now, it's the standard of care in the second line in the United States, with all patients basically getting this second-line therapy except for some unique patients where they may be doing a PATINA trial regimen, which we saw at San Antonio Breast Cancer in 2024 of the triple-positive patients getting hormonal therapy plus palbociclib, which had a really great durable response. That was super impressive as well. Or there is the patient that the investigator can pick KADCYLA because the patient really wants to preserve their hair or maybe it's more indolent disease. But the quality of life on T-DXd indefinitely in the first-line setting is a big deal because, again, that CLEOPATRA regimen allows patients to drop their chemotherapy component about five to six months in. And with this, you're on a drug that feels very chemo-heavy indefinitely. And so, I think there's a lot more to investigate as far as what we're going to do with this data in the United States because it's a lot to commit a patient in the first-line metastatic setting. These de novo metastatic patients, some of them may be cured, honestly, on the HER2-targeting regimen. That's something we see these days. Dr. Allison Zibelli: So, very interesting trial. I'm sure we'll be talking about this for a long time. So, let's move on to SERENA-6, which was, I thought, a very interesting trial. This trial took patients with ER positive, advanced breast cancer after six months on an AI (aromatase inhibitor) and a CDK4/6 inhibitor. They did ctDNA every two to three months, and when they saw an ESR1 mutation emerge, they changed half of the patients to camizestrant plus CDK4/6 and kept the other half on the AI plus CDK4/6. Can you talk about that trial a little bit, please? Dr. Rebecca Shatsky: Yeah, so this was a big trial at ASCO25. This was presented as a Plenary Session. So, this was camizestrant plus a CDK4/6 inhibitor, and it could have been any of the three, so palbo, ribo, or abemaciclib in the first-line metastatic hormone-positive population, and patients were on an AI with that. They were, interestingly, tested by ctDNA at baseline to see if they had an ESR1 mutation. So, that was an interesting feature of this trial. But patients had to have already been on their CDK4/6 inhibitor plus AI for at least 6 months to enroll. And then, as you mentioned, they got ctDNA testing every 2 to 3 months. This was also a phase 3, double-blind, international trial. And I do want to highlight again, international here, because that's important when we're considering some of this data in the U.S. because it influences some of the results. So, this was presented by Dr. Nick Turner of the Royal Marsden in the UK. So, just a little bit of background for our listeners on ESR1 mutations and why they're important. This is the most common, basically, acquired resistance mutation to patients being treated with aromatase inhibitors. We know that treatment with aromatase inhibitors can induce this. It makes a conformational change in the estrogen receptor that makes the estrogen receptor constitutively active, which allows the cell to signal despite the influence of the aromatase inhibitor to decrease the estrogen production so that the ligand binding doesn't matter as much as far as the cell signaling and transcription is concerned. And camizestrant, you know, as an oral SERD, just to explain that a little bit too; these are estrogen receptor degraders. The first-in-class of a selective estrogen receptor degrader to make it to market was fulvestrant. And that's really been our standard-of-care estrogen degrader for the past 25 years, almost 25 years. And so, a lot of us are just looking for some of these oral SERDs to replace that. But regardless, they do tend to work in the ESR1-mutated population. And we know that patients on aromatase inhibitors, the estimates of patients developing an ESR1 mutation, depending on which study you look at, somewhere between 30% to 50% overall, patients will develop this mutation with hormone-positive metastatic breast cancer. There is a small percentage of patients that have these at baseline without even treatment of an aromatase inhibitor. The estimates of that are somewhere between 0.5 and up to 5%, depending on the trial you look at and the population. But regardless, there is a chance someone on their CDK4/6 inhibitor plus AI at 6 months' time course could have had an ESR1 mutation at that time. But anyway, so they got this ctDNA every 2 to 3 months, and once they were found to develop an ESR1 mutation, the patients were then switched to the oral SERD. AstraZeneca's version of the oral SERD is camizestrant, 75 mg daily. And then their type of CDK4/6 inhibitor was maintained, so they didn't switch the brand of their CDK4/6 inhibitor, importantly. And that was looked at then for progression-free survival, but these were patients with measurable disease by RECIST version 1.1. And the data cut off here was November of 2024. This was a big trial, you know, and I think that that's influential here because this was 3,256 patients, and that's a lot of patients. So, they were all eligible. And then 315 patients ended up being randomized to switch to camizestrant upon presence of that ESR1 mutation. So, that was 157 patients. And then the other half, so they were randomized 1:1, they continued on their AI without switching to an oral SERD. That was 158 patients. They were matched pretty well. And so, their baseline characteristics, you know, the two subgroups was good. But this was highly statistically significant data. I'm not going to diminish that in any way. Your hazard ratio was 0.44. Highly statistically significant confidence intervals. And you had a median progression-free survival in those that switched to camizestrant of 16 months, and then the non-switchers was 9.2 months. So, the progression-free survival benefit there was also consistent across the subgroups. And so, you had at 12 months, the PFS rate was 60.7% for the non-treatment group and 33.4% in the treatment group. What's interesting, though, is we don't have overall survival data. This is really immature, only 12% mature as far as overall survival. And again, because this was an international trial and patients in other countries right now do not have the access to oral SERDs that the United States does, the crossover rate, they were not allowed to crossover, and so, a very few patients, when we look at progression-free survival 2 and ultimately overall survival, were able to access an oral SERD in the off-trial here and in the non-treatment group. And so, that's really important as far as we look at these results. Adverse events were pretty minimal. These are very safe drugs, camizestrant and all the other oral SERDs. They have some mild toxicities. Camizestrant is known for something weird, which is called photopsia, which is some flashing lights in the periphery of the eye, but it doesn't seem to have any serious clinical significance that we know of. It has a little bit of bradycardia, but it's otherwise really well tolerated. You know, I hate to say that because that's very subjective, right? I'm not the one taking the drug. But it doesn't have any serious adverse events that would cause discontinuation. And that's really what we saw in the trial. The discontinuation rates were really low. But overall, I mean, this was a positive trial. SERENA-6 showed that switching to camizestrant at the first sign of an ESR1 mutation on CDK4/6 inhibitor plus AI improved progression-free survival. That's all we can really say from it right now. Dr. Allison Zibelli: So, let's move on to ASCENT-04, which was a bit more straightforward. Sacituzumab govitecan plus pembrolizumab versus chemotherapy plus pembrolizumab in PD-L1-positive, triple-negative breast cancer. Could you talk about that study? Dr. Rebecca Shatsky: Yeah, so this was also presented by the lovely Sara Tolaney from Dana-Farber. And this study made me really excited. And maybe that's because I'm a triple-negative breast cancer person. I mean, not to say that I don't treat hundreds of patients with hormone- positive, but our unmet needs in triple negative are huge because this is a disease where you have got to throw your best available therapy at it as soon as you can to improve survival because survival is so poor in this disease. The average survival with metastatic triple-negative breast cancer in the United States is still 13-18 months, and that's terrible. And so, for full disclosure, I did have this trial open at my site. I was one of the site PIs. I'm not the global PI of the study, obviously. So, what this study was was for patients who had had at least a progression-free survival of 6 months after their curative intent therapy or de novo metastatic disease. They were PD-L1 positive as assessed by the Dako 22C3 assay of greater than or equal to a CPS score of 10. So, that's what the KEYNOTE-355 trial was based on as well. So, standard definition of PD-L1 positive in breast cancer here. And basically, these patients were randomized 1:1 to either their sacituzumab govitecan plus pembrolizumab, day 1 they got both therapies, and then day 8 just the saci, as is standard for sacituzumab. And then the other group got the KEYNOTE-355 regimen. So, that is pembrolizumab with – your options are carbogem there, paclitaxel or nab-paclitaxel. And it's up to investigator's decision which upon those they decided. They followed these patients for disease progression or unacceptable toxicity. It was really an impressive trial in my opinion because we know already that this didn't just improve progression-free survival, because survival is so poor in this disease, of course, we know that it improved overall survival. It's trending towards that very much, and I think that's going to be shown immediately. And then the objective response rates were better, which is key in this disease because in the first-line setting, you've got a lot of people who, especially your relapsed TNBC that don't respond to anything. And you lose a ton of patients even in the first-line setting in this disease. And so, this was 222 patients to chemotherapy and pembro and 221 to sacituzumab plus pembro. Median follow-up has only been 14 months, so it's still super early here. Hazard ratio so far of progression-free survival is 0.65, highly statistically significant, narrow confidence intervals. And so, the median duration of response here for the saci group was 16.5 months versus 9.2 months. So, you're getting a 7-month progression-free survival benefit here, which in triple negative is pretty fantastic. I mean, this reminds me of when we saw the ASCENT data originally come out for sacituzumab, and we were all just so happy that we had this tool now that doubled progression-free and overall survival and made such a difference in this really horrible disease where patients do poorly. So, OS is technically immature here, but it's really trending very heavily towards improvement in overall survival. Importantly, the treatment-related adverse events in this, I mean, we know sacituzumab causes neutropenia, people who are experienced with this drug know how to manage it at this point. There wasn't any really unexpected treatment-related adverse events. You get some people with sacituzumab who have diarrhea. It's usually pretty manageable with some Imodium. So, it was cytopenias predominantly in this disease in this population that were highlighted as far as adverse events. But I'm going to be honest, like I was surprised that this wasn't the plenary over the SERENA-6 data because this, in my mind, there we have a practice-changing trial. I will immediately be trying to use this in my PD-L1 population because, to be honest, as a triple-negative breast cancer clinical specialist, when I get a patient with metastatic triple-negative breast cancer who's PD-L1 positive, I think, "Oh, thank God," because we know that part of the disease just does better in general. But now I have something that really could give them a durable response for much longer than I ever thought possible when I started really heavily treating this disease. And so, this was immediately practice-changing for me. Dr. Allison Zibelli: I think that it's pretty clear that this is at least an option, if not the option, for this group of patients. Dr. Rebecca Shatsky: Yeah, the duration of responses here was – it's just really important because, I mean, I do think this will make people live longer. Dr. Allison Zibelli: So, moving on to the final study that we're going to discuss today, neoCARHP (LBA500), which was neoadjuvant taxane plus trastuzumab, pertuzumab, plus or minus carbo(platin) in HER2-positive early breast cancer. I think this is a study a lot of us have been waiting for. What was the design and the results of this trial? Dr. Rebecca Shatsky: I was really excited about this as well because I'm one of those people that was waiting for this. This is a Chinese trial, so that is something to take note of. It wasn't an international trial, but it was a de-escalation trial which had become really popular in HER2-positive therapy because we know that we're overtreating HER2-positive breast cancer in a lot of patients. A lot of patients we're throwing the kitchen sink at it when maybe that is not necessary, and we can really de-escalate and try to personalize therapy a little bit better because these patients tend to do well. So, the standard of care, of course, in HER2-positive curative intent breast cancer with tumors that are greater than 2 cm is to give them the TCHP regimen, which is docetaxel, carboplatin, trastuzumab, and pertuzumab. And that was sort of established by several trials in the NeoSphere trial, and now it's been repeated in a lot of different studies as well. And so, that's really the standard of care that most people in the United States use for HER2-positive curative intent breast cancer. This was a trial to de-escalate the carboplatin, which I was super excited about because many of us who treat this disease a lot think carbo is the least important part of the therapy you're giving there. We don't really know that it's necessary. We've just been doing it for a long time, and we know that it adds a significant amount of toxicity. It causes thrombocytopenia, it causes severe nausea, really bad cytopenias that can be difficult in the last few cycles of this to manage. So, this trial was created. It randomized patients one to one with stage 2 and 3 HER2-positive breast cancer to either get THP, a taxane, pertuzumab, trastuzumab, similar to the what we do in first-line metastatic HER2-positive versus the whole TCHP with a carboplatin AUC of 6, which is what's pretty standard. And it was a non-inferiority trial, so important there. It wasn't to establish superiority of this regimen, which none of us, I think, were looking for it to. And it was a modified intent-to-treat population. And so, all patients got at least one cycle of this to be assessed as a standard for an intent-to-treat trial. And so, they assumed a pCR rate of about 62.8% for both groups. And, of course, it included both HER2-positive triple positives and ER negatives, which are, you know, a bit different diseases, to be honest, but we all kind of categorize them and treat them the same. And so, this trial was powered appropriately to detect a non-inferiority difference. And so, we had about 380 patients treated on both arms, and there was an absolute difference of only 1.8% of those treated with carbo versus those without. Which was fantastic because you really realized that de-escalation here may be something we can really do. And so, the patients who got, of course, the taxane regimen had fewer adverse events. They had way fewer grade 3 and 4 adverse events than the THP group. No treatment-associated deaths occur, which is pretty standard for- this is a pretty safe regimen, but it causes a lot of hospitalizations due to diarrhea, due to cytopenias, and neutropenic fever, of course. And so, I thought that this was something that I could potentially enact, you know, and be practice-changing. It's hard to say that when it's a trial that was only done in China, so it's not necessarily the United States population always. But I think for patients moving forward, especially those with, say, a 2.5 cm tumor, you know, node negative, those, I'd feel pretty comfortable not giving them the carboplatin here. Notes that I want to make about this population is that the majority were stage 2 and not stage 3. They weren't necessarily your inflammatory HER2-positive breast cancer patients. And that the taxane that was utilized in the trial is a little different than what we use in the United States. The patients were allowed to get nab-paclitaxel, which we don't have FDA approval for in the first-line curative intent setting for HER2-positive breast cancer in the United States. So, a lot of them got abraxane, and then they also got paclitaxel. We tend to use docetaxel every 3 weeks in the United States. So, just to point out that difference. We don't really know if that's important or not, but it's just a little bit different to the population we standardly treat. Dr. Allison Zibelli: So, are there patients that you would still give TCHP to? Dr. Rebecca Shatsky: Yeah, great question. I've been asked that a lot in the past like week since ASCO. I'd say in my inflammatory breast cancer patients, that's a group I do tend to sometimes throw the kitchen sink at. Now, I don't actually use AC in those because I know that that was the concern, but I think the TRAIN-2 trial really showed us you don't need to use Adriamycin in HER2-positive disease unless it's like refractory. So, I don't know that I would throw this on my stage 3C or inflammatory breast cancer patients yet because the majority of this were not stage 3. So, in your really highly lymph node positive patients, I'm a little bit hesitant to de-escalate them from the start. This is more of a like, if there's serious toxicity concerns, dropping carbo is absolutely fine here. Dr. Allison Zibelli: All right, great.

Welcome to the Oncology Brothers podcast! In this episode, Drs. Rahul and Rohit Gosain are joined by Dr. Erika Hamilton from the Sarah Cannon Research Institute to discuss the latest breakthroughs in breast cancer presented at the ASCO 2025 annual meeting. We dived into five key abstracts that could change the landscape of breast cancer treatment: 1. INAVO120: observed overall survival data with the combination of inavolisib, with palbociclib and fulvestrant for patients with PIK3CA mutated hormone receptor-positive, HER2-negative advanced breast cancer. 2. SERENA-6: camizestrant use in patients with emerging ESR1 mutations using ctDNA, showed significant improvement in progression-free survival. 3. VERITAC-2: vepdegestrant showed superior progression-free survival compared to fulvestrant, particularly in ESR1 mutated patients. 4. DESTINY-Breast09: significant improvement in progression-free survival with TDXd plus pertuzumab in frontline HER2-positive metastatic breast cancer, challenging the traditional CLEOPATRA regimen THP. 5. ASCENT-04: promising results of sacituzumab combined with pembrolizumab in PD-L1 positive triple-negative breast cancer.

The 2025 American Society of Clinical Oncology (ASCO) Annual Meeting featured five days of presentations and educational sessions on all types of cancer. Dr. Eleonora Teplinsky, a board-certified medical oncologist at the Valley-Mount Sinai Comprehensive Cancer Center in Paramus, NJ, summarizes the top breast cancer research. Listen to the episode to hear Dr. Teplinsky discuss: The SERENA-6 trial, which found that if metastatic hormone receptor-positive, HER2-negative breast cancer develops ESR1 mutations during first hormonal therapy treatment, switching to camizestrant from an aromatase inhibitor before the cancer grows improves outcomes. Results from the DESTINY-Breast09 trial showing that the combination of Enhertu (chemical name: fam-trastuzumab-deruxtecan-nxki) and Perjeta (chemical name: pertuzumab) is a better first treatment for metastatic HER2-positive breast cancer than the current standard of THP chemo. The ASCENT-04/KEYNOTE-D19 trial, which found that people with metastatic, PD-L1-positive, triple-negative breast cancer fared better with the combo of Trodelvy (chemical name: sacituzumab govitecan-hziy) and Keytruda (chemical name: pembrolizumab) as a first treatment compared to people who received chemotherapy and Keytruda.
Dr. John Sweetenham shares highlights from Day 3 of the 2025 ASCO Annual Meeting, including new research for the treatment of advanced renal cell carcinoma and 2 studies on novel approaches in non-small cell lung cancer. Transcript Dr. John Sweetenham: Hello, I'm Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my takeaways on selected abstracts from Day 3 of the 2025 ASCO Annual Meeting. Today's selection features studies addressing the treatment of advanced renal cell carcinoma and 2 studies exploring novel approaches in non-small cell lung cancer. My disclosures are available in the transcript of this episode. The first abstract is number 4505. This study, led by Dr. Toni Choueiri of the Dana-Farber Cancer Institute, describes the final analysis of the CheckMate 214 trial, which compared the combination of nivolumab and ipilimumab with sunitinib for the first-line treatment of advanced renal cell carcinoma. The ipi-nivo combination is approved for the frontline treatment of intermediate and poor-risk advanced renal cell carcinoma based on the primary analysis of the CheckMate 214 trial, which demonstrated a higher response rate and longer overall survival compared with sunitinib. Today's presentation provided the final safety and efficacy results for the trial with long-term follow-up of more than 9 years. The intent-to-treat (ITT) population in this trial comprised 550 patients randomized to nivo and ipi versus 546 who received sunitinib. The final analysis showed sustained long-term benefit for the combination therapy. Patients given nivolumab plus ipi had a 29% reduction in the risk for death compared with sunitinib. For patients with intermediate or poor-risk disease, there was a 31% reduction in the risk of death. The probability of remaining in response through 8 years was more than doubled with nivolumab plus ipilimumab versus sunitinib in the ITT population at 48% versus 19%, and in the intermediate and poor-risk population at 50% versus 23%. The other important observation is that patients with favorable-risk disease appeared to have a 20% reduction in the risk for death at 9 years and more durable responses. This suggests a possible delayed benefit for ipi and nivo in this group since these differences were not seen in the earlier analysis. No new safety signals emerged with longer follow-up, and the results confirm the use of ipi and nivo as a standard front-line combination therapy in this disease. Since this combination has been in widespread use for some years, the results are not surprising although the subgroup analysis suggesting benefit in favorable-risk patients is likely to inform practice in the future. Today's second abstract is number is 8506, which was presented by Dr. Tony Mok from the Chinese University of Hong Kong, describing results from the phase 3 HERTHENA-Lung02 trial. This trial compared the antibody-drug conjugate patritumab deruxtecan with platinum-based chemotherapy in patients with EGFR-mutated advanced non-small cell lung cancer following a third-generation tyrosine kinase inhibitor (TKI). Patritumab deruxtecan, also known as HER3-DXd, comprises a fully human anti-HER3 IgG3 monoclonal antibody conjugated to a topoisomerase 1 inhibitor payload, and showed activity in a previous phase 2 trial in patients relapsing after EGFR TKI and chemotherapy. In this phase 3 study, this agent was compared with platinum-based chemotherapy in eligible patients with an EGFR-activating mutation who had previously received 1 or 2 EGFR TKIs, at least one of which was a third-generation drug, with relapse or progression after this therapy. Five hundred and eighty-six patients were enrolled, with progression-free survival as the primary endpoint. The primary analysis showed a 9-month progression-free survival of 29% for the experimental arm compared with 19% for platinum-based chemotherapy, for a hazard ratio of 0.77 and a P value of 0.011. With higher progression-free survival rates at 6 months and 12 months, HER3-DXd also had a better objective response rate (35.2% versus 25.3%) compared with platinum-based chemotherapy (PBC), and HER3-DXd also extended intracranial progression-free survival compared with PBC in patients with brain metastases, with a hazard ratio of 0.75. Grade 3 or more treatment-related adverse events occurred in 73% of patients treated with HER3-DXd and 57% of patients who received PBC. HER3-DXd had a higher rate of grade or more 3 thrombocytopenia, and drug-related interstitial lung disease occurred in 5% of patients in the HER3-DXd arm. The follow-up will need more time to mature since no overall survival data are currently available, but definitely an agent to watch with interest. Moving on to today's final abstract, 8500, was presented by Dr. Pasi Jänne from the Dana-Farber Cancer Institute, describing results from the phase 2 portion of the KRYSTAL-7 study. This study is exploring the use of a potent KRAS inhibitor, adagrasib, in combination with pembrolizumab in patients with advanced or metastatic KRASG12C- mutated non-small cell lung cancer. Adagrasib has already received accelerated approval in the U.S. for previously treated locally advanced or metastatic NSCLC with a KRASG12C mutation. A previous report from the KRYSTAL-7 study demonstrated encouraging activity in combination with pembrolizumab in the frontline setting for this patient group who also had more than 50% expression of PD-L1. The presentation today described efficacy and safety data for this drug combination across all PD-L1 expression levels. One hundred and forty-nine patients with a median age of 67 years were treated with the combination, 104 of whom had PD-L1 expression level results available, representing the so-called biomarker population in this trial. The overall response rate for the entire study population was 44%. In the biomarker population, the overall response rate ranged from 36% in those with less than 1% PD-L1 expression to 61% for those with more than 50% expression. For all patients, the median response duration was just over 26 months, and the median progression-free and overall survival rates were 11 and 18.3 months respectively. For the biomarker population, the median progression-free and overall survival were highest in those patients with more than 50% PD-L1. No new safety issues emerged from this analysis; the most frequent toxicities were nausea, diarrhea, and increases in transaminases. Immune-related toxicities included pneumonitis, hypothyroidism, and hepatitis. These are important results and the results of the phase 3 portion of KRYSTAL-7, which compares first-line therapy with adagrasib plus pembro versus pembro alone in the KRASG12C mutated/PD-L1 more than 50% group, will be informative. For those patients with lower levels of PD-L1 expression, the authors suggest that the treatment escalation may be beneficial, possibly including the addition of chemotherapy. That concludes today's report. Thanks for listening and I hope you will join me again tomorrow to hear more top takeaways from ASCO25.

JCO Editorial Fellow Dr. Peter Li and JCO Associate Editor Dr. Andrew Ko discuss the ASCO 25 Simultaneous Publication paper "Lenvatinib Plus Pembrolizumab and Chemotherapy Versus Chemotherapy in Advanced Metastatic Gastroesophageal Adenocarcinoma: The Phase III Randomized LEAP-015 Study." Transcript The guest on this podcast episode has no disclosures to declare. Dr. Peter Li: Hello, everyone, and welcome to our 2025 ASCO Annual Meeting Series where we cover some of the top JCO papers published simultaneously with their abstract presentation at this year's meeting. I'm your host, Dr. Peter Li, JCO Editorial Fellow, and I'm joined by Dr. Andrew Ko, JCO Associate Editor, to discuss the Journal of Clinical Oncology article and abstract presentation "Lenvatinib Plus Pembrolizumab and Chemotherapy Versus Chemotherapy in Advanced Metastatic Gastroesophageal Adenocarcinoma: The Phase III Randomized LEAP-015 Study." Now, let's start off with the relevance of this article. Andrew, can you please explain this to our listeners? Dr. Andrew Ko: Sure. Thanks, Peter. So, this was a very large international study evaluating the combination of lenvatinib and pembrolizumab. And just for context, that combination has been approved for use in other solid tumor types. It's FDA approved for renal cell carcinoma, for example, and endometrial carcinoma. But this study was looking specifically at this combination together with a chemotherapy backbone - so either FOLFOX or CAPOX - and comparing that to what at the time was a standard of care, which was just standard chemotherapy by itself. So, this very large study was intending to look at this particular novel combination. And we can get into some of the nuances of this study because the way that the experimental, the combination arm, was designed was perhaps a little bit more on the unusual side and led to maybe some imbalance in terms of how we think about the respective arms. Dr. Peter Li: Okay. We can definitely talk more about that as we go on. So, what are some of the key results of this study, and how do you think this will impact practice in the future? Dr. Andrew Ko: That's a good question. Technically, it was not a positive study. Well, it was positive in the sense that the co-primary endpoints - which included both progression-free survival and overall survival - so, progression-free survival, it did technically meet its endpoint, both in terms of the overall population and the preplanned subgroup analysis of patients who had a PD-L1 CPS of greater than or equal to 1. So, there was a PFS benefit with the experimental combination - the lenvatinib, pembrolizumab, plus chemotherapy - compared to chemotherapy alone. I will say the benefit was on the more modest side. So, if you even look at the medians, it was not a marked difference. If you look at the hazard ratios, they did meet statistical significance. On the other hand, this did not translate into a benefit for overall survival. So, when you ask, "Well, is this going to inform practice?" I'd have to say no. It highlights, I think, that JCO does want to publish articles that aren't necessarily going to be practice-changing, but that I think offer a lot of insights into trial design and important aspects of investigating novel treatments, even if they don't end up moving the needle in routine clinical practice. Dr. Peter Li: I totally agree with you. I mean, it was significant in terms of progression-free survival, but again, not clinically significant. And then overall survival, the interventional arm actually appeared to do slightly worse overall. Can you make some comments on the strengths and the weaknesses of this study, and where do you see us going from here? Dr. Andrew Ko: So, I think a couple of things worth highlighting in this study, very well designed, more than 800 patients in total. So, first of all, as I mentioned at the beginning, the combination was a little bit unique in terms of patients enrolled to the experimental arm got the combination of lenvatinib, pembrolizumab, together with chemotherapy for a very finite duration. So, that period of chemotherapy they received was only three months. And per protocol, patients then just segued to, quote unquote “maintenance treatment” with just the lenvatinib and pembrolizumab combination. Whereas patients on the control arm, meaning chemotherapy alone, would continue chemotherapy basically in perpetuity until their disease progressed or intolerable toxicity. So, there really was an imbalance in terms of, if you think that chemotherapy or continuing chemotherapy beyond that initial three-month period of time may be significant, that could have had some impact on the robustness or the efficacy of the experimental arm. There were some other aspects in terms of perhaps some differences in the rates of post-progression treatment, in other words, patients going on to receive second-line treatment. I think the other very relevant aspect, Peter, in this study was that the control arm - and no fault of the investigators - but the control arm at the time the study was ongoing just consisted of chemotherapy, FOLFOX CAPOX, by itself, without an immune checkpoint inhibitor, right? And we clearly know, based on results of several large phase III studies, and it's now in standard clinical practice, that we routinely use chemotherapy plus an immune checkpoint inhibitor. Certainly for patients with CPS PD-1/PD-L1 scores that are, well, you could argue greater than 1, or perhaps greater than 5 or 10. But the point being that the control arm of the study probably doesn't reflect what is currently used in clinical practice. And that's just always a challenge in clinical trial design, right? That when a study is designed and when it rolls out, you're always at risk in a rapidly changing and moving field that the standard of care may evolve during the lifetime of that particular trial, which is what I think you see in LEAP-015. Dr. Peter Li: Totally understand. And the survival we see from this study is also roughly similar to the combination of immuno-chemotherapy that is the standard of care today, which is, the authors mentioned, 12 to 14 months. Thank you so much, Andrew, for your input and for speaking about the JCO article "Lenvatinib Plus Pembrolizumab and Chemotherapy Versus Chemotherapy in Advanced Metastatic Gastroesophageal Adenocarcinoma: The Phase III Randomized LEAP-015 Study."

JCO Editorial Fellow Dr. Ece Cali Daylan and JCO Associate Editor Dr. Grant McArthur discuss the ASCO 2025 Simultaneous Publication paper "A Phase II (Alliance A091802) Randomized Trial of Avelumab Plus Cetuximab vs. Avelumab Alone in Advanced Cutaneous Squamous Cell Carcinoma (cSCC)." Transcript The guest on this podcast episode has no disclosures to declare. Dr. Ece Cali: Hello, and welcome to our 2025 ASCO Annual Meeting series where we cover some of the top JCO papers published simultaneously with their abstract presentation at this year's meeting. I'm your host, Dr. Ece Cali, and I'm joined by JCO Associate Editor Dr. Grant McArthur. Today, we will discuss Journal of Clinical Oncology article and abstract presentation "A Phase II Randomized Trial of Avelumab Plus Cetuximab Versus Avelumab Alone in Advanced Cutaneous Squamous Cell Carcinoma." Let's start with a brief overview of the clinical trial. This is a randomized phase II trial that compared avelumab plus cetuximab to avelumab in PD-1/PD-L1 antibody-naive patients with advanced cutaneous squamous cell carcinoma. This is a cooperative group study conducted in the United States. Sixty patients were randomized one-to-one and stratified by PD-L1 and HIV status. The primary endpoint was progression-free survival. Patients on the cetuximab plus avelumab arm had a median PFS of 11.1 months, while patients on the avelumab arm had a median PFS of 3 months, corresponding to a hazard ratio of 0.48 with a p-value of 0.018. Grade III or higher treatment-related adverse events occurred in 48% of the patients on the combination arm versus 21% of patients on the avelumab arm. Dr. McArthur, can you please explain to our listeners how you interpret this data? Dr. Grant McArthur: These results are very important because they provide proof of concept for inhibiting PD-L1 as a target when combined with EGFR, so inhibiting PD-L1 with avelumab and inhibiting EGFR with cetuximab, in a randomized trial with a very significant impact in terms of efficacy. So, what this does is it provides proof of concept for inhibiting those targets in cutaneous squamous cell carcinoma of the skin. Avelumab is not approved for cutaneous squamous cell carcinoma of the skin, and so further studies would need to be done, particularly asking the question about combination with the approved PD-1 agents cemiplimab and pembrolizumab. Dr. Ece Cali: I still find the difference in median PFS with various PD-1/PD-L1 inhibitors striking in this context. In this trial, avelumab, as you mentioned, the PD-L1 inhibitor, demonstrated a median PFS of 3 months, whereas PD-1 inhibitors cemiplimab and pembrolizumab have demonstrated longer median PFS in other trials. So, what are some potential reasons for this, and do you think this difference impacts the interpretation of the results here? Dr. Grant McArthur: So, the obvious reason for the differences is that avelumab targets PD-L1, where pembrolizumab and cemiplimab inhibit PD-1, so there could be simply a difference in the target to explain those differences in progression-free survival. However, as you point out, cross-trial comparisons, one has to do with caution because you can, in different phase II studies, enroll different patient populations, which would impact the progression-free survival. So, we have to be cautious about that interpretation. However, given that cemiplimab and pembrolizumab are the approved agents, I think they are the logical ones for further clinical development. Nonetheless, this is still a very important proof-of-concept trial showing that there is a strong clinical signal when you combine EGFR inhibition with inhibition of PD-L1 versus PD-L1 alone. Dr. Ece Cali: I want to highlight some of the safety data presented in this trial as well. The treatment discontinuation rate due to adverse events was much higher in the combination arm, reaching 31% compared to the 14% in the single-agent avelumab arm. The most common grade III adverse events were infusion reaction, rash, and diarrhea in the combination arm. So, these adverse events may affect patients' quality of life significantly. So, what are your thoughts on this, Dr. McArthur? Dr. Grant McArthur: So, the safety data is important. What we're seeing is safety related to each individual agent. So, we have diarrhea and skin rash from the cetuximab, and the infusion reactions is a common toxicity of avelumab. I think what's important, given this is proof of concept inhibiting these targets going forward to further studies, is that agents such as cemiplimab and pembrolizumab have a very low infusion reaction rate. So, the treatment discontinuations due to infusion reaction are unlikely to be an issue with cemiplimab and pembrolizumab when further clinical trials are done. Of course, there is still the issue of diarrhea and skin rash. Now, that can be managed in many patients with EGFR inhibition, you know. However, one would have to await safety data from a significant patient cohort with a combination of cetuximab with either cemiplimab or pembrolizumab, of course, to assess the clinical impact of those safety signals. But I would expect there to be definitely rash and diarrhea as predominant toxicities with those other combinations as well. Dr. Ece Cali: And lastly, I think we touched upon this a little bit, but how do you think this trial impacts the clinical practice, and what are some outstanding questions that need to be addressed in this field in light of the data from this trial? Dr. Grant McArthur: So, the most important outstanding question is - of course, we've already alluded to in our conversation - regarding using anti-PD-1 agents such as pembrolizumab or cemiplimab. So, that needs to be undertaken. Clearly, a randomized trial would be required combining cetuximab with those agents because they are quite active as single agents with impressive response rates and PFS. So, that is the way forward. There's other important clinical questions as well, though. So, patients that get locally aggressive or metastatic cutaneous squamous cell carcinoma of the skin are often immunosuppressed. And so, we do need data in patients that are immunosuppressed, either due to treatment of immune-related disorders - and also organ transplantation. We see a lot of cutaneous squamous cell carcinoma in organ transplant patients. So, these are important patient subsets that would also need to be investigated in further clinical development. However, overall, you know, this is a strong signal, hazard ratio of less than 0.5, and very worthy of further investigation in randomized trials of inhibiting these targets. Dr. Ece Cali: This was a great discussion. Thank you so much for your insight, Dr. McArthur, for speaking about the JCO article "A Phase II Randomized Trial of Avelumab Plus Cetuximab Versus Avelumab Alone in Advanced Cutaneous Squamous Cell Carcinoma."

BUFFALO, NY - May 21, 2025 – A new #review was #published in Volume 16 of Oncotarget on May 19, 2025, titled “Advancements in bladder cancer treatment: The synergy of radiation and immunotherapy." Researchers from the University of California, Irvine, led by Nazmul Hasan, reviewed recent clinical and scientific advances in combining radiation therapy with immunotherapy for bladder cancer. The article summarizes growing evidence that this combined approach may strengthen the immune response and improve long-term disease control. This strategy is especially important for patients who are not candidates for surgery or who respond poorly to conventional treatments. Bladder cancer is a serious and frequent condition, particularly affecting older men. Traditional treatments—surgery, chemotherapy, and radiation—can be effective, but they often fail to prevent cancer reappearance in advanced cases. The review explores how combining radiation and immunotherapy could improve outcomes by helping the immune system detect and destroy cancer cells more effectively. Radiation therapy destroys cancer cells and triggers the release of tumor signals that attract immune cells. Immunotherapy, including drugs like pembrolizumab and nivolumab, helps the immune system work better by blocking proteins that allow cancer to evade detection. Used together, these treatments may produce a stronger, more widespread anti-tumor effect, even at distant sites not directly targeted by radiation. The review discusses several clinical trials that support this approach. One phase II study reported that combining radiation with the immunotherapy drug durvalumab led to promising survival rates and manageable side effects. Another trial in Australia tested pembrolizumab with radiation and chemotherapy, resulting in high tumor control and extended patient survival. However, the review also points out that other trials showed serious side effects when high doses or multiple immunotherapy drugs were used at once. "Joshi et al. performed a phase II study to determine the safety and efficacy of combining radiation therapy with durvalumab, a PD-L1 inhibitor, in patients who were ineligible for surgery or cisplatin-based chemotherapy." While the combination approach is promising, the authors emphasize that more research is needed to refine this treatment strategy. One major challenge is determining which patients are most likely to benefit. Future studies should focus on identifying reliable biomarkers, such as tumor mutation burden or immune activity, to guide personalized treatment plans. This review highlights the potential of combining radiation and immunotherapy to improve outcomes for bladder cancer patients. With continued research and careful treatment design, this approach could offer new treatment options for those facing aggressive or hard-to-treat forms of the disease.

Highlights From This Episode “Unfortunately, because lung cancer is pretty aggressive, we'll see lung cancer mostly in stage IV. So about 50%–55% of all cases are not caught until they are already metastatic, or stage IV. And then about another 25%–30% of cases are caught in stage III, which means they're locally advanced and often not resectable, but we do still treat that with curative intent with concurrent chemoradiation. And then 10%–20% of cases are found in the early stage, and that's stage I and II, where we can do surgical approaches.” TS 2:53 “The majority of radiation that you're going to see is for patients with stage III disease that's inoperable. At my institution, a lot of stage III is inoperable. Now, neoadjuvant immunotherapy has changed that a little bit. But if you have several big, bulky, mediastinal lymph nodes that makes you stage III, surgery is probably not going to be a great option. So we give curative-intent chemoradiation to these patients.” TS 10:51 “Oligoprogression would mean they have metastases but only to one site. And sometimes we will be aggressive with that. Particularly, there's good data, if the only site of progression is in the brain, we can do stereotactic radiation to the brain and then treat the chest with concurrent chemoradiation as a more definitive approach. But outside of that, the majority of stage IV lung cancer is going to be treated with systemic therapy.” TS 15:00 “It's important for nurses to know that there's a lot of different options now for treatment. Probably one of the most important things is making sure patients are aware of what their biomarker status is, what their PD-L1 expression level is, and make sure those tests have been done. … It's good that the patients understand that there's a myriad of options. And a lot of that depends on what we know about their cancer, and then that guides our treatment.” TS 31:05

BUFFALO, NY - April 28, 2025 – A new #research paper was #published in Oncotarget, Volume 16, on April 24, 2025, titled “PD-L1 and FOXP3 expression in high-grade squamous intraepithelial lesions of the anogenital region." Researchers Humberto Carvalho Carneiro, Rodrigo de Andrade Natal, José Vassallo and Fernando Augusto Soares from the Instituto D'Or de Pesquisa e Ensino and Rede D'Or studied early tissue changes caused by human papillomavirus (HPV) in the anal, vulvar, and penile regions. They found that high-grade pre-cancer lesions triggered stronger immune responses and showed higher levels of two immune-related markers, PD-L1 and FOXP3. These findings are important because they help explain how some HPV-related lesions progress to cancer while others heal on their own. High-risk HPV is known to cause several types of anogenital cancers. Before these cancers appear, the virus often leads to abnormal tissue changes known as high-grade squamous intraepithelial lesions. Many of these lesions disappear without treatment, but some become cancer—especially in people with weakened immune systems. This study explored how immune activity may play a role in this progression. The researchers examined tissue from 157 patients—95 males and 55 females—with either high-grade or low-grade HPV-related lesions. They found that T-regulatory cells, marked by the FOXP3 protein, were more common in high-grade lesions. These immune cells are known to suppress immune responses, which can allow infected or abnormal cells to grow. The team also found higher expression of PD-L1, a protein that helps cells evade immune detection, particularly in inflammatory immune cells. "Dense inflammatory infiltrates and high counts of FOXP3+ cells were significantly more frequent in patients with HSILs than in those with LSILsHR (p = 0.04 and 0.02, respectively). HSILs also exhibited higher PD-L1 expression (padj < 0.01 and < 0.01 for the SP142 and 22C3 clones, respectively), based on the Poisson generalized linear model.” These findings suggest that HPV may begin avoiding the immune system early in infection, even before cancer develops. The combination of high FOXP3 and PD-L1 levels may create a protective environment for infected cells, making them harder for the body to eliminate. This immune evasion may allow the lesions to remain and, over time, become cancerous. The study also compared patients with and without HIV to assess whether immune health influenced the results. While those with compromised immune systems had more extensive lesions, PD-L1 and FOXP3 expression was also found in patients with healthy immune systems. This evidence shows that immune evasion by HPV can happen regardless of a person's immune status. Understanding how PD-L1 and FOXP3 function in early HPV-related lesions may help clinicians predict which lesions are more likely to become cancer. These insights could lead to new strategies for monitoring, treating, or preventing HPV-related precancerous lesions and cancer in the anogenital region. The study highlights how early immune system changes can play a key role in the development of HPV-related cancers.

In today's episode, supported by Summit Therapeutics, we had the pleasure of speaking with Xiuning Le, MD, PhD, about the use of ivonescimab (SMT112) in patients with PD-L1–positive non–small cell lung cancer (NSCLC). Dr Le is an associate professor in the Department of Thoracic/Head and Neck Medical Oncology in the Division of Internal Medicine at The University of Texas MD Anderson Cancer Center in Houston. The phase 3 HARMONi-2 trial (NCT05499390) investigated ivonescimab vs pembrolizumab (Keytruda) in patients with locally advanced or metastatic, PD-L1–positive NSCLC without sensitizing EGFR mutations or ALK translocations. At the preplanned interim analysis, at a median follow-up of 8.7 months (IQR, 7.1-10.3), the median progression-free survival was significantly longer in the ivonescimab arm (n = 198) vs the pembrolizumab arm (n = 200), at 11.1 months (95% CI, 7.3-not estimable) vs 5.8 months (95% CI, 5.0-8.2), respectively (stratified HR, 0.51; 95% CI, 0.38-0.69; 1-sided P < .0001). The objective response rates were 50% (95% CI, 43%-57%) and 39% (95% CI, 32%-46%) in these respective arms. In our exclusive interview, Dr Le discussed the rationale for the HARMONi-2 trial, key findings from the study, and where these findings position the potential role of ivonescimab in the PD-L1–positive NSCLC treatment paradigm.

Dr. Shannon Westin and her guest, Dr. Breelyn Wilky, discuss the JCO article, "“Botensilimab (Fc-enhanced anti-cytotoxic lymphocyte-association protein-4 antibody) Plus Balstilimab (anti-PD-1 antibody) in Patients With Relapsed/Refractory Metastatic Sarcomas." TRANSCRIPT Shannon Westin: Hello, everyone, and welcome to another episode of JCO After Hours, the podcast where we get in depth on research that has been published in the Journal of Clinical Oncology. I am your host, Gynecologic Oncologist and Social Media Consultant Editor of the JCO, Shannon Westin. I serve here from the University of Texas MD Anderson Cancer Center. And I am so excited to welcome Dr. Breelyn Wilky. She's an Associate Professor and the Director of Sarcoma Medical Oncology in the Department of Medicine Division of Medical Oncology, and the Cheryl Bennett & McNeilly family endowed chair in Sarcoma Research, the Deputy Associate Director of Clinical research at the University of Colorado Cancer Center. Welcome. Dr. Breelyn Wilky: Thank you so much. I'm delighted to be here. Shannon Westin: And with all those titles, I'm super impressed that she was able to complete the manuscript that we're going to discuss today, which is “Botensilimab (Fc-enhanced anti-cytotoxic lymphocyte-association protein-4 antibody) Plus Balstilimab (anti-PD-1 antibody) in Patients With Relapsed/Refractory Metastatic Sarcomas.” And this was published in the JCO on January 27, 2025. And please note, our participants do not have any conflicts of interest. So this is exciting. Let's first level set. Can you review with us just the current state of sarcoma incidents, survival outcomes, that kind of thing so we all know where we're starting? Dr. Breelyn Wilky: Yes. So, you know, sarcomas are really, I like to call them the black box cancer type. And the big thing is that there's really more than a hundred different kinds of sarcomas, which collectively altogether make up only 1% of adult cancers. And so we talk about these as being bone and soft tissue tumors, but really, the heterogeneity is just incredible. You're talking maybe 10,000 to 12,000 new cases of soft tissue sarcoma per year, which is pretty rare in the grand scheme of things. And the trouble with these is that while you can cure sarcomas if you find them early and they're localized, when they metastasize and spread and are not resectable, we're looking at median overall survivals of really only 12 to 18 months, even, you know, with our best therapies that we have. So, really there's just a dire need for new treatments for this really tough group of diseases. Shannon Westin: Yeah, I agree. I'm a gynecologic oncologist, and we have our little subset of sarcomas that I know there's a little bit out of every one. So I'm really excited to pull this manuscript as one of our podcasts offerings because I think we're all seeing these patients in the clinic and certainly our listeners that have sarcoma or have family members with sarcoma, this is so good to have a real focus on a rare group of tumors that have been a little bit lumped together. Now, with that being said, I know this is such a heterogeneous population, but can you briefly overview a little bit around the standard of care for treatment of recurrent sarcomas? Dr. Breelyn Wilky: We have actually been using the same drugs really since about the 1970s, and up until very recently, nothing had really challenged doxorubicin, the old ‘red devil', like we used to call it. And this has been the mainstay of treatment for metastatic sarcomas and really used across the board. In the GYN literature, for uterine leiomyosarcoma, we did see some promising activity with the combination of doxorubicin and trabectedin coming out of the French group. But, except for that study, no combination therapy or new drug has been proven better in terms of overall survival compared to doxorubicin monotherapy, really over 40, 50 years. So it's definitely a tough situation. Now, we do have other drugs that we use, so most patients will wind up getting doxorubicin-based therapy. There's a couple of other regimens that we'll reach to, like gemcitabine docetaxel. And once you get into the specific subtypes, we have some approvals in liposarcomas and leiomyosarcomas for some other drugs. But really the median progression for survival for most of these regimens is somewhere four to six months. And response rates typically are somewhere like 10%, 15% for most of these. So it's really just a very tough field and a tough group of patients to try to make an impact for. Shannon Westin: So let's talk a little bit more kind of getting focused on what you've studied here. What's been the role of immunotherapy thus far in the treatment of sarcomas maybe prior to this particular study? Dr. Breelyn Wilky: Clearly, we all know that immune therapy has just changed cancer care forever over the last few years for so many different types of cancers and diseases like melanoma and renal cell and lung cancer have just been transformed by checkpoint inhibitors specifically directed against PD-1 or CTLA-4 or both. And so, of course, you know, sarcoma docs we're super excited to try to see if these might potentially have activity in our tumors as well. I never had seen myself in my career getting into immunotherapy until I was able to run an investigator-initiated study during my role in Miami, where we combined pembrolizumab, so PD-1 inhibitor, with axitinib which was a pan-VEGF inhibitor. And lo and behold, like I had patients that I was seeing responses when other treatments, all those chemotherapies I was just talking about had failed. And one of my first patients I treated was about a 60-year-old lady with something called cutaneous angiosarcoma. So this is a blood vessel sarcoma all over her face. And we had treated her with 10 different therapies, all the chemotherapy regimens, targeted therapies, clinical trials, and nothing was working. But I put her on a phase 1 trial with a baby dose of CTLA-4 and this woman had a complete response. And so for me, once I saw it work in even just those couple of patients, like that was nothing that we'd ever seen with our chemotherapy regimens. And so that sort of shifted my career towards really focusing on this, and this is about the time where some of the studies started to come out for sarcomas. And the take home with sarcoma is about 20% of sarcomas have this sort of immune hot physiology. So what that basically means is if you look at gene expression of immune related gene signatures, or you look for infiltrating T-cells, sort of the SWAT team of our immune system, like you can find those in the tumors. And it's sort of evidence that the immune system had some clue for that 20% of patients that this was a foreign tumor and that it should be attacking it and maybe just needed a little help. But globally, about 80% of sarcomas are these immune cold tumors, which means the immune system has no clue that these things are even a threat. And there's almost no immune activation, very, very few antigens. In other cancer types, high neoantigens or tumor antigens help the immune system work better. And so that basically goes with what we've seen with trials of PD-1 or CTLA-4 blockade. About 20% of sarcomas, with some exceptions, can respond. But really 80% across the board, you're stuck, you just can't get them to be recognized. And so that's where I think this data is so interesting is there's some signals of activity in these immune cold tumors which, at least historically with the trials we've done so far, we really haven't seen that with sort of the traditional checkpoints. Shannon Westin: So I think now this is a great time to maybe talk about the study design in general, the eligibility and just give us kind of a run through of that. Dr. Breelyn Wilky: So this trial was a phase 1 trial of a drug called botensilimab, which is a next generation CTLA-4 directed immune modulator. So what makes botensilimab different is that the CTLA-4 end is very similar to other CTLA-4 inhibitors that are out there, but it's been engineered on the back end of the molecule that binds to Fc gamma receptors to basically bind tighter with higher affinity. And what this translates to in laboratory models and increasingly now in patients is it does a better job of priming, of educating our T cells, our, again, these highly intelligent antigen specific cells, but also natural killer cells. It does a better job of sort of educating those. It helps to activate macrophages and other supporting actors in the immune response. And so the idea here is that there's evidence that botensilimab may do a better job at creating new responses in immune cold tumors. The study combined either botensilimab as monotherapy or in combination with a PD-1 inhibitor called balstilimab. And this was all comers, really a variety of tumor types. And to date I think we're close to about 500 patients with a variety of solid tumors that have been accrued to this study, this C-800-01 phase 1 trial. This paper reports on the sarcoma patients that were enrolled as part of this study. And so, again, given what I've told you about sarcomas being really immune cold, we were just so excited to have the opportunity to enroll on a next generation immune therapy for these tumors that really we were running into roadblocks trying to use immunotherapy previously. Shannon Westin: It's a very compelling idea and I'm so excited for you to tell people what you found. I think first things first, it was an early phase trial. So why don't we talk a little bit about the safety of the regimen. Was there anything that you didn't expect? Dr. Breelyn Wilky: Right. So similar to other checkpoint inhibitors, you know, the idea is that these drugs can cause immune mediated toxicities, right? So essentially you're revving up the immune system and it can sometimes get a bit confused and start attacking our normal cells, our normal organs, leading to essentially any number of toxicities of basically head to toe, something can get inflamed and you can develop a toxicity from that. So the key take homes with this particular drug with, botensilimab with balstilimab, we saw colitis was sort of the primary immune mediated toxicity and it was about a third of patients, give or take. It happens and it can be aggressive and needs to be managed aggressively. And you know, one of the things that we learned very quickly taking part in this study is how important it is that as soon as patients start to get diarrhea, immunosuppression gets on board. So steroids, early use of TNF alpha blockade, so infliximab for example, if we jumped on it quickly and we recognized it and we got the patients treated, it would resolve fairly quickly and even some patients could remain on treatment. So I think that was sort of the first take home is “Okay if you get colitis, you treat it fast, you treat it early and you can still have patients not only recover, which essentially everybody recovered from this colitis and then being able to continue on treatment and still have their anti-tumor responses.” So that's the first point. The second thing that was really interesting is part of the engineering of botensilimab on the back end of the molecule, it's been designed to decrease complement binding and it's thought that that triggers some of these other toxicities that we've seen with prior CTLA-4 inhibitors like pneumonitis or hypophysitis. We actually don't see that with botensilimab. So there's sort of this selective toxicity that may reflect the design of the molecule. But overall the treatment was, we didn't see any new safety signals that were outside of what we would expect in class. And colitis was sort of the dominant thing that we had to be ready for and ready to manage. Shannon Westin: We've been doing it for a while now, so we kind of know what to do and we can act quickly and really try to mitigate and avoid some of the major toxicities. So that's great that that was what was reflected in what you found. And then of course I think: What about the efficacy?” Right. This is what we care about as practitioners, as patients. Does it work and are there any subtypes that seem to benefit the most from this combination? Dr. Breelyn Wilky: Right. So for the sarcoma patients, we treated 64 patients and 52 of those patients were evaluable for efficacy. So a decent size group of patients in sarcomas, where, you know, typically our trials are pretty small, they're very rare, but we had 52 evaluable with at least one post baseline scan. So that was our criteria. And basically we saw across all of the patients, and keep in mind, these are heavily pre-treated patients, as you mentioned, so a median of 3 prior lines of therapy, so most of these patients had had chemotherapies and then about 20% had also had prior immunotherapy as well. So PD-1 treatments or so on. The overall response rate by RECIST was 19.2% for all of the evaluable patients. And then with iRECIST, which is sort of that immune adapted response criteria that allows for early pseudo progression, we actually had another patient who did have that. And so that response rate was 21.2%. Overall, we were really excited to see this in a heavily pre-treated group of patients. But what was really exciting to me was when we looked at the subset of patients that had angiosarcoma, that blood vessel tumor I was talking about earlier with my other patient. So angios come in two flavors. One is this sort of cutaneous type, or meaning involving the skin that has a UV signature, a UV damage signature, very similar to melanoma. So these tumors tend to have a high mutation burden. And oftentimes there is a track record that we've seen responses with immunotherapy in cutaneous angiosarcomas. But the other group that we deal with is called visceral angiosarcomas. And so these are totally different biologically. These are often driven by mutations in MYC or KDR amplification, and they arise in organs, so primary breast angiosarcoma, not associated with radiation, or they can arise in the liver or the spleen or an extremity. So these are very, very different tumors, and the visceral ones almost never historically have responded to checkpoint inhibitors. So we had 18 patients with angio split - 9 with cutaneous, 9 with visceral. And we were just blown away because the response rate for that group was 27.8%. And if you looked at the responses between the hot ones and the cold ones, it was almost equal and a little bit better in the visceral. So we had a 33% response rate in visceral angiosarcoma, which is crazy, historically speaking, and about 20% again in the cutaneous angios. So for a disease where visceral angio gets treated with chemotherapy, might respond initially, but then rapidly progresses - like these people go through multiple lines of therapy - to have a third of patients responding, and then some of those responses were durable. Our median duration of response for the study was 21.7 months, which is just nuts for sarcomas where we just don't see those sorts of long term benefits with the drugs that we have. So I think those are kind of the two main things. There were other subtypes that had clinical benefit and responses as well in d-diff liposarcoma, soft tissue leiomyosarcoma, which are again thought to be fairly cold immune subtypes. So just really exciting to kind of see responses we hadn't expected in a very challenging group of tumors. Shannon Westin: We see all these patients and we have patients that respond so well to immunotherapy with other histotypes. And so it's so exciting to see an option for these really hard to treat tumors that our patients struggle with. So this is so, so very exciting. I wanted to make mention, you know, I was really impressed with the amount of translational work you were able to do in this early phase study. So do you want to review just maybe a few of the key findings that you guys discovered? Dr. Breelyn Wilky: It's always great. I'm a translational researcher at heart and we do a lot of immune correlative work. And I think the reason I got so excited about this field to begin with was trying to learn why it works for some patients and why it doesn't work for other patients. So I'm a huge believer in learning from every patient that we can. So it's such a testament to the company, Agenus, who sponsored this trial to invest their time and resources into correlative studies at this phase. It's huge. So we learned a couple of things. IL-6 or interleukin 6 is a cytokine that basically has, in other tumor types, been associated with worse outcomes. And what we were interested in this group is we saw the same thing. And again, sarcomas have very, very little correlative biology that's done. We're really in infancy and understanding the microenvironment and how that milieu balances out in our tumors. So we were really excited to see again that lower peripheral interleukin 6 associated with improved overall survival. So again, kind of sorting out a group of patients that might be immunologically favorable when it comes to this type of therapy. The other thing that's important to know about sarcoma is so the other tumor types are lucky and have PD-L1 expression and the tumor is a biomarker, but we never have PD-L1 expression. We can find it in sarcomas and it can be loosely correlated with a chance of benefit with immunotherapy. But I've had patients respond that were PD-L1 negative, and I've had patients that were loaded with PD-L1 that didn't seem to make a difference. And that's not just in this study. So we saw in this trial a trend towards improved overall survival with PD-L1 expression that wasn't significant, but there was like this trend. And it's really interesting because, again, this is largely a CTLA-4 directed therapy. And so what we wondered is if PD-L1 expression is an index of sort of this underlying potential immunogenicity. And actually PD-1 works very late in the whole immune process. That's really at the very end where you've got the T cell that's facing the tumor cell and it's just activating that T cell that's already grown up and already educated and ready to go. Whereas CTLA-4 is really educating in early immune responses and expanding the T cells that have potential to kill. So I'm interested to look into this in more depth in the future to see if this is actually the biomarker for CTLA-4 directed therapy that we've been looking for, because we really don't have a great sense about that. And then the last piece just to note is that in this trial, like most others, very, very few sarcomas had high mutational burden. Everybody was very low, which reflects the population. And it's just really more encouragement than an immune cold tumor with very crappy neoantigens can still respond to immunotherapy if we get them the right agents. Shannon Westin: Yeah, I mean, I'm taking notes because we have such a struggle with this across the gynecologic tumors. I'm like, “Okay, maybe this is finally it.” So hopefully your work will go on to really inspire us across a number of solid tumors that have been traditionally cold. So, so very exciting. And I would just say for my last question, obviously, congratulations on this successful study. What do you think are the next steps for this combination in sarcomas? Dr. Breelyn Wilky: So, again, just to your point, this trial enrolled a bunch of different subtypes, and sarcomas are not the only immune cold tumor that this combo has looked really promising for, microsatellite stable colorectal cancer, ovarian cancer that was platinum refractory, non-small cell lungs. So I think the future is really bright for immune cold tumors kind of across the board. So, yes, lots of hope for not just sarcomas but in terms of our patients, I just have to be so grateful to Agenus for their interest in a rare disease. Sometimes it's hard to get that interest for a very challenging group of patients that are all heterogeneous, they are not all the same and our big clinical trials are a few hundred patients. It's just a very different environment. But they have been so supportive and involved in making sure that sarcomas are represented in their priorities. So there are ongoing discussions about what the optimal way to explore this further in sarcomas is going to be and I cannot wait to have the official plans in place. But my hope is this will not be the last that we see of these drugs for our patients. Shannon Westin: Well, I support that and my vote is on your side. So, thank you so much again, Dr. Wilky. This time just flew by. This was such a great discussion and I mean, I think it's, again, a testament to your exciting data. And thank you to all of our listeners.

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

Dr. Jyoti Patel is back on the podcast to discuss the updates to the living guideline on therapy for stage IV NSCLC with driver alterations. She shares updated recommendations in the first- and second-line settings for patients with stage IV NSCLC and classical EGFR mutations, and the impact of these updates for clinicians and patients. We also look to the future to discuss ongoing developments in the field.

TRANSCRIPT This guideline, clinical tools, and resources are available at http://www.asco.org/living-guidelines. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest in the Journal of Clinical Oncology, https://ascopubs.org/doi/10.1200/JCO-24-02785 Brittany Harvey: Welcome to the ASCO Guidelines Podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges and advances in oncology. You can find all the shows including this one at asco.org/podcasts. My name is Brittany Harvey and today I'm interviewing Dr. Jyoti Patel from Northwestern University, co-chair on “Therapy for Stage IV Non-Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2024.3.” It's great to have you back on the show today, Dr. Patel. Dr. Jyoti Patel: Thanks so much. Happy to be here. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Patel, who has joined us here today, are available online with the publication of the guideline and in the Journal of Clinical Oncology, which is linked in the show notes. So then, to dive into the content of this update, Dr. Patel, this clinical practice guideline for systemic therapy for patients with stage IV non small cell lung cancer with driver alterations is living, meaning that it's continuously reviewed and updated. So what data prompted this latest change to the recommendations? Dr. Jyoti Patel: Thanks so much. So it's really been an exciting time in the treatment of EGFR lung cancer, particularly this past year has required us to rethink approaches to front- and second-line therapy. In this particular update, we examined what patients in the front-line setting may be offered by their clinicians. And so we're talking about the population of classical EGFR mutations, so exon 19 and exon 21 L858R substitution. And so certainly for this population, osimertinib has a high level of evidence and should be offered to all patients at the time of diagnosis when they present with advanced disease. Our last update included a recommendation that patients could also get platinum doublet chemotherapy with osimertinib or osimertinib alone. This current recommendation also introduces another alternative therapy and that's the combination of amivantamab plus lazertinib. And so now, clinicians are faced with three really good options for their patients with EGFR exon19 deletion or L858R. Brittany Harvey: It's great to hear that there's this advance in the space, particularly for patients with these classical EGFR mutations that you mentioned. So what should clinicians know as they implement these new first-line recommendations? Dr. Jyoti Patel: I think it's become more complex than ever. Certainly, we know again that patients should get osimertinib in the frontline setting. But we've been kind of stuck at progression-free survival that's between a year and a half and two years. And so we've really been looking at opportunities to intensify therapy. So one could certainly be with chemotherapy or switching over to amivantamab, the bispecific antibody that targets EGFR and MET plus lazertinib, an oral TKI that's very similar in structure to osimertinib. And when you're talking to a patient, it's really a conversation about balancing efficacy with toxicity. Unfortunately, as we know, there aren't that many free lunches. And so if we think about what a patient is hoping for in their therapy and how we can further personalize treatment options, really is important to look at some of the analyses for this study. So in the study of amivantamab plus lazertinib, we know that there were increased toxicities with a combination of both therapies. In fact, up to 75% of patients had over grade 3 toxicities, versus about 43% of patients with osimertinib monotherapy. And we know if we look back at FLAURA2, almost two thirds of patients with osimertinib and chemotherapy had grade 3 toxicities, compared to 27% of patients with osimertinib alone. So we certainly see an increase in toxicities. Then we have to ask ourselves, are those paper toxicities or ones that really impact patients? And we know that amivantamab, for example, causes significant cutaneous toxicities. With both of these therapies, whether it's chemotherapy or adding amivantamab, there's the burden of infusional visits and increased time in the doctor's office. Certainly with chemotherapy, there can be an increased incidence of myelosuppression. And so when we're thinking about advising our patients, certainly we need to talk about the toxicities. But one thing that we've been able to do is to look at the patients that were included in this trial. And what we really find is that in higher risk cohorts, particularly those that we know historically have done less well with standard osimertinib, so patients, for example, with CNS metastasis, for those patients with co-mutations, it may be that that additive benefit is significant. And so one example I think would be from the MARIPOSA study, again, the study of amivantamab and lazertinib versus chemotherapy. What we can say is that patients who had co-mutations, so patients with EGFR mutations as well as TP53, lazertinib and amivantamab led to a hazard ratio of 0.65 compared to osimertinib alone. So that was 18.2 months versus 12.9 months. And so this may be really important to patients. And we also see conversely that patients with wild type TP53, so those patients who didn't have the mutation, probably had equivalent survival regardless of therapy. So certainly, we need to prospectively study some of these high-risk cohorts. We've only seen progression-free survival in these studies. And so at this juncture, we can advise our patients about toxicity, the improvements in certain categories of progression-free survival, but we really still don't know how this pans out in overall survival. In many of these studies, all patients do not necessarily cross over to the study arm and so they may have lost the benefit of subsequent therapy. Brittany Harvey: Absolutely. It's very important to talk about that balance of benefits and risks and particularly those toxicities that you discussed. So I appreciate reviewing that recommendation and the considerations for clinicians for first-line therapy. This update also included a second-line treatment update. What is that update for patients with EGFR alterations? Dr. Jyoti Patel: So this is where it gets super tricky because we have a frontline option with amivantamab and now we've had an update in the second line option. So what we said is that for patients who have progressed on an EGFR TKI, and in the United States, certainly that's predominantly osimertinib, or those in other parts of the world that may have gotten an earlier generation TKI, but do not have evidence of T790M or other targetable mutations, we can offer patients chemotherapy with or without amivantamab. And so certainly we have seen that this again leads to improved survival. There have also been a number of studies looking at incorporation of PD-L1 and anti-VEGF therapies. And what we can say, I think pretty clearly is that multiple phase 3 trials have really shown no benefit of the addition of PD-1 to platinum chemotherapy. But there are some emerging bispecific antibodies that may target PD-1 as well as VEGF, or combinations of antibodies that target both of those pathways that may improve outcome. At this juncture, I think we feel that the evidence surrounding chemotherapy plus amivantamab is strongest, but there is certainly work in this space that will be of interest. Now, what happens if your patient received amivantamab and lazertinib in the frontline setting and then has progression? And so we're trying to understand resistance mechanisms and opportunities for treatment. What the panel decided to recommend, based on the available evidence, was that certainly those patients should get platinum-based chemotherapy, but there may also be a role for antivascular endothelial growth factor targeting therapy such as bevacizumab in patients in whom it would be safe. Brittany Harvey: Great. I appreciate you detailing those recommendations when it gets complicated in the second-line setting. So what should clinicians know as they implement these second-line recommendations too? Dr. Jyoti Patel: So certainly the frontline setting matters significantly. So if a patient gets osimertinib in the frontline setting, we generally suggest that patients undergo repeat testing to see if they have another targetable mutation. If they don't, then I think preferred therapy would be chemotherapy with or without amivantamab. And amivantamab leads to a significant improvement in progression-free survival and response rate at the cost of increased risk of toxicity. For patients who get FLAURA2 in the frontline setting, chemotherapy plus osimertinib, it's a little bit of an unclear space. Those patients most likely would get docetaxel with or without ramucirumab. But there are other agents that we hope to have available to our patients in the near future. For patients who receive amivantamab and osimertinib, we recommend that those patients get chemotherapy probably with anti-VEGF as demonstrated by multiple trials that have shown the improved progression-free survival with introduction of an anti-VEGF agent. And we've seen evidence of amivantamab in the third line setting, so it is likely that this question about sequencing really takes center stage in our next set of trials. When you're talking to a patient, I think again, it's absolutely important to discuss: What are their goals? How symptomatic or how fast is their progression? Are there ways in which patients may benefit from spot treatment oligoprogression such as radiation? When is the right time for introduction of amivantamab and when do we think patients need chemotherapy? Is it up front or predominantly in the second-line setting? Brittany Harvey: Definitely. And then you've just touched on the goals of treatment for individual patients. So in your view, what does this update mean for patients with stage IV non-small cell lung cancer and an EGFR alteration? Dr. Jyoti Patel: For patients, this is a time in which shared decision making really needs to take center stage. So our best patients are those patients that are best informed not only about their disease but also have a good understanding about what is important to them and their families in terms of care. And so bringing that shared understanding to the table again helps us think about this particular cancer as more of a journey rather than just a one off treatment. Therapy will hopefully be prolonged, and so it's absolutely important that we address toxicities, make therapies more tolerable, again, with the shared goal of living long and living well. Brittany Harvey: Absolutely. Those are key points to making sure that patients are living both longer and have a good quality of life during that time as well. So then, before you mentioned the possibility of future sequencing trials and other ongoing developments. What additional studies or future directions is the panel examining for future updates to this living guideline? Dr. Jyoti Patel: So certainly we're thinking about trials that look at, for example, cfDNA clearance. So are there patients that do well and can we detect that early on without having to intensify therapy on day 1 so it may be that we add chemotherapy a little bit later. I think really exciting are some of the new bispecific. The HARMONi-A trial was a trial in China of a novel bispecific, ivonescimab. And this drug targets both PD-1 and VEGF and it was combined with chemotherapy. And this trial found almost a doubling of progression-free survival with this drug in combination chemotherapy in an EGFR patient population. That study is being planned and being run in the United States to see if we have similar outcomes with a more diverse population. So certainly that's exciting. There are a number of antibody drug conjugates that are being studied in the post-chemotherapy setting as well. And I think we'll likely soon see a better understanding of what co-mutations and burden of disease really mean when we're thinking about assigning treatment. So which patients, again, need intensification of therapy and which patients may do really well on just an oral agent that they're taking at home with more tolerable toxicity than dual treatment. Brittany Harvey: Yes, we'll look forward to continued developments in these fields and seeing some of those studies come to fruition. So with that, I want to thank you for your work to rapidly and continuously update this guideline, and thank you for your time today, Dr. Patel. Dr. Jyoti Patel: Thanks so much, Brittany. It's really an exciting time for lung cancer and we hope that these updates really help physicians decide the best treatments for their patients. Again, it's a rapidly evolving landscape which is fantastic, but it does become more cumbersome to stay ahead of the literature. Brittany Harvey: Definitely. And so we appreciate your time and the panel's time spent reviewing this literature and providing this much needed information to clinicians everywhere.

Dr. Lyudmila Bazhenova joins us again to share the newest changes to the living guideline on therapy for stage IV NSCLC without driver alterations. She discusses new evidence reviewed by the panel and changes to second-line recommendations for patients with good performance status and HER2 overexpression, and what these updates mean in practice. We discuss ongoing evidence generation as we await further updates to these living guidelines. Read the full living guideline update “Therapy for Stage IV Non-Small Cell Lung Cancer Without Driver Alterations: ASCO Living Guideline, Version 2024.3” at www.asco.org/living-guidelines. TRANSCRIPT This guideline, clinical tools, and resources are available at http://www.asco.org/living-guidelines. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest in the Journal of Clinical Oncology, https://ascopubs.org/doi/10.1200/JCO-24-02786 Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey and today I'm interviewing Dr. Lyudmila Bazhenova from University of California San Diego Moores Cancer Center, co-chair on “Therapy for Stage IV Non–Small Cell Lung Cancer Without Driver Alterations: ASCO Living Guideline, Version 2024.3.” It's great to have you back on the show today, Dr. Bazhenova. Dr. Lyudmila Bazhenova: It's my pleasure to be here as always. Brittany Harvey: Great. Then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the entire guideline panel, including Dr. Bazhenova, who has joined us here today, are available online with the publication of the guide in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into the content here, first, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer without driver alterations has frequent updates to the recommendations. What prompted this latest update? Dr. Lyudmila Bazhenova: Living ASCO guidelines are created to keep up with rapidly changing evidence which affect treatment of our patients with lung cancer. As a committee, we review published literature on a specific topic at the regular intervals and determine if it alters any recommendations. This time, upon our literature review, we felt that there are new data that requires an update in the guidelines and therefore the guidelines were updated. Brittany Harvey: Great. Thank you for that updated information. So then it looks like the panel updated recommendations for second line and subsequent treatment options for patients with good performance status and HER2 overexpression. What is that updated recommendation from the panel? Dr. Lyudmila Bazhenova: Yes, this is correct. We now added an extra recommendation for patients with stage IV non-small cell lung cancer who have overexpression of the protein called HER2. HER2 overexpression with 2+/3+ level via immunohistochemistry is seen in approximately 8% to 20% of patients with lung cancer. And the data behind our recommendation comes from the DESTINY-Lung01 trial where patients with HER2 overexpression were treated with trastuzumab deruxtecan. And we saw that if patients with stage IV non-small cell lung cancer had a HER2 IHC score of 3+, overall response rate was seen at 53% and median duration of response was 6.9 months and, therefore, that in our opinion qualified for updated recommendation. We are still waiting for additional results that will be released later on another clinical trial where we see preliminary data presented at the World Conference of Lung Cancer in 2024. They looked at 36 patients also with HER2 overexpression and saw the overall response rate of almost 45%. It is important to highlight in this smaller study that a majority of the patients in the study were actually having EGFR mutation and the response rate in those patients who had an EGFR mutation was higher than the response rate in patients without EGFR mutations who just had a HER2 overexpression. So for now this is updated in the guidelines, but we will wait for additional data or formal publication of a World Lung Conference presentation and see if those recommendations need to be changed. Brittany Harvey: Understood, and I appreciate you providing the context of some of those ongoing developments as well. So then what should clinicians know as they implement this updated recommendation? Dr. Lyudmila Bazhenova: Number one, we should all start from remembering to test for HER2 via immunohistochemistry. There is a slight difference in what considers HER2 positive in lung versus breast. In lung, we use what's called the gastric scoring and the difference is the circumferential versus non circumferential staining of the membrane. And number two, immunohistochemistry is not always included in next generation sequencing panels. So when you order your next generation sequencing, I think it's important to know if your company that you're using is testing for HER2 via immunohistochemistry. And if it's not, make sure that you find a company that does or work with your local pathology department to make sure that this testing is offered. It is also important to know the difference between HER2 overexpression and HER2 exon 20 insertion mutation even though the treatment for those two abnormalities is the same, which is trastuzumab deruxtecan. But the benefit that you can cite your patients and the rigor of the literature supporting the usage of trastuzumab deruxtecan in mutation versus overexpression is different. Brittany Harvey: Yes. And as you mentioned, it's essential that, in the first place, patients are actually receiving the testing so that we know if they're eligible for these treatment options. So what additionally does this change mean for patients with stage IV non-small cell lung cancer and HER2 overexpression? Dr. Lyudmila Bazhenova: So for patients, it adds another treatment modality which is now FDA approved. So if there are patients listening to me, make sure that your physician has tested your tumor for HER2 overexpression. So I think proactive asking of your physician would be very appropriate in this situation. Brittany Harvey: Absolutely. And then earlier you mentioned an ongoing trial that the panel was looking to for the future. But what other additional trials did the panel review during this guideline update and what is the panel examining for future updates to this living guideline? Dr. Lyudmila Bazhenova: So at this point we reviewed three additional studies. The results of those studies did not make it into a change in guidelines. So we reviewed the HARMONi-2 trial. HARMONi-2 trial so far does not have an official publication and, as per our strategy on how we come up with ASCO guidelines, we need to wait for an official publication. So this is one thing we're going to be expecting in the future. Once this is published, we will review it and decide if we need to make an additional change in recommendations. For those of you who are not aware, HARMONi-2 trial used bispecific monoclonal antibody against VEGF and PD-1 and was a phase III randomized trial comparing their investigational product which is called ivonescimab over pembrolizumab for patients with PD-L1 more than 50. And again, we are waiting for the final publication to make our recommendation. The second trial we reviewed was a LUNAR trial and the LUNAR trial looked at addition of tumor treating fields to chemotherapy or immunotherapy in patients whose cancer progressed with platinum doublet. The key point about this study is that immunotherapy was not required to be administered in a first line setting which is a current standard of care in the United States. And even though the study met their primary endpoint of overall survival, there were more benefits in patients who were immunotherapy naive in the second line. And we felt that given the potential lifestyle implication of wearing a device for 18 hours per day, and the lack of evidence in immunotherapy-pretreated population, and the absence of data in the first-line setting where we currently using immunotherapy in the United States, we felt that there is insufficient data to definitely recommend addition of tumor treating fields to systemic chemotherapy for most patients. And we are waiting for additional trials that are ongoing in this setting to formalize or change our recommendations. And we also reviewed- the final study that we reviewed was TROPION-Lung01. TROPION-Lung01 study was a phase III study in post platinum doublet setting which compared efficacy of Dato-DXd and docetaxel and trials showed improvement in progression free survival but not in overall survival. And progression free survival benefit was more pronounced in non-squamous carcinoma histology subgroup and we felt that the results do appear promising, but the strength of evidence which was based on unplanned subgroup analysis was not sufficient enough to make a change in treatment recommendation at this time. Brittany Harvey: I appreciate your transparency on why some of that data did not prompt a change to recommendations at this time.

In a conversation with CancerNetwork®, Marwan G. Fakih, MD, spoke about the FDA approval of sotorasib (Lumakras) plus panitumumab (Vectibix), and how it may affect the treatment paradigm for patients with KRAS G12C-mutant metastatic colorectal cancer (CRC). Fakih is a professor in the Department of Medical Oncology & Therapeutics Research, associate director for Clinical Sciences, medical director of the Briskin Center for Clinical Research, division chief of GI Medical Oncology, and co-director of the Gastrointestinal Cancer Program at City of Hope Comprehensive Cancer Center in Duarte, California. According to Fakih, the approval of this combination regimen is a “welcome step” for those with metastatic CRC harboring KRAS G12C mutations. Based on supporting data from the phase 3 CodeBreaK 300 trial (NCT05198934), sotorasib/panitumumab may prolong progression-free survival (PFS) and reduce disease burden in patients while offering improvements in other outcomes vs prior standards of care (SOC) like trifluridine/tipiracil (Lonsurf) and regorafenib (Stivarga). Topline data at the time of the approval showed a median PFS of 5.6 months (95% CI, 4.2-6.3) with sotorasib at 960 mg plus panitumumab vs 2.0 months (95% CI, 1.9-3.9) in the SOC arm, in which patients were assigned to receive trifluridine/tipiracil or regorafenib (HR, 0.48; 95% CI, 0.30-0.78; P = .005). Additionally, the overall response rate was 26% (95% CI, 15%-40%) vs 0% (95% CI, 0%-7%) in each respective arm. Looking ahead, Fakih highlighted the potential next steps for research associated with the sotorasib combination as well as other novel therapeutic strategies in the gastrointestinal cancer space. For example, he described the phase 3 CodeBreaK 301 study (NCT06252649), which will evaluate sotorasib/panitumumab as frontline therapy when administered in combination with folinic acid, fluorouracil, and irinotecan (FOLFIRI) vs FOLFIRI plus bevacizumab (Avastin) in metastatic KRAS G12C-mutant CRC. Other novel agents under development in the space include RAS inhibitors and immunotherapy regimens combining CTLA-4 inhibitors with anti–PD-L1 agents. References 1.

In this JCO Article Insights episode, Ece Cali summarizes findings from the JCO article, "Datopotamab Deruxtecan Versus Docetaxel for Previously Treated Advanced or Metastatic Non–Small Cell Lung Cancer: The Randomized, Open-Label Phase III TROPION-Lung01 Study." TRANSCRIPT Ece Cali: Hello and welcome to the JCO Article Insights. I'm your host Ece Cali and today we will be discussing the Journal of Clinical Oncology article the “Datopotamab Deruxtecan Versus Docetaxel for Previously Treated Advanced or Metastatic Non–Small Cell Lung Cancer: The Randomized, Open-Label Phase III TROPION-Lung01 Study.” Despite significant advances in non-small cell lung cancer treatment over the past decades, second line treatment options for non-small cell lung cancer without actionable genomic alterations have remained largely unchanged since 2000. Many clinical trials failed to demonstrate improved overall survival compared to docetaxel based regimens. TROPION-Lung01 is a global open label randomized phase 3 trial comparing the efficacy and safety of Dato-DXd to docetaxel in patients with previously treated advanced or metastatic non-small cell lung cancer. Dato-DXd is an antibody drug conjugate targeting TROP2 and delivering deruxtecan, a DNA topoisomerase 1 inhibitor, as its payload. The trial is designed with dual primary endpoints of progression free survival, as assessed by blinded independent central review, and overall survival. The initial PFS results were presented at ESMO in 2023 and this article reports more detailed data and overall survival analysis of the trial. In the TROPION-Lung01, 299 patients were randomly assigned to receive Dato-DXd and 305 patients to receive docetaxel. Patients were stratified by the presence of actionable genomic alterations, histology, treatment with PD-1/PD-L1 immunotherapy as the last line of therapy, and geographical region. The baseline characteristics of the patient population were overall balanced between the treatment arms. I'd like to highlight a couple of key points here. The median age was 63 years in the Dato-DXd and 64 years in the docetaxel arm. Similar to the many clinical trials in the thoracic oncology field, this is younger than the median age of lung cancer diagnosis in the US, which is around 70. African American and Hispanic patients were underrepresented in this trial with 41% of patients identifying themselves as white and 39% as Asian. The Ddocetaxel arm had a slightly higher percentage of male patients, 69% versus 61%. The majority of the trial population, 73%, had adenocarcinoma. Patients with actionable genomic alterations were included in this trial if they received one or more targeted therapy and platinum based chemotherapy prior to the enrollment. 17% of the trial population had an actionable genomic alteration in this trial. When it comes to the efficacy results in the full analysis set, the PFS improvement was statistically significant. The median PFS was reported as 4.4 months for the Dato-DXd, and 3.7 months for the docetaxel arm with the hazard ratio of 0.75 and a P value of 0.004. However, after a median follow up of 23 months, the trial did not meet its primary endpoint of overall survival. The median overall survival was 12.9 months for patients treated with Dato-DXd and 11.8 months for patients treated with docetaxel with the hazard ratio of 0.94 and a P value of 0.53. Objective response was a secondary endpoint and the confirmed objective response rate was 26% with Dato-DXd, and 13% with docetaxel. Now let's take a closer look at some of the subgroup analyses. Exploratory analyses of key subgroups in TROPION-Lung01 demonstrated differences in efficacy based on histology. In the nonsquamous subgroup, Dato-DXd showed a longer progression free survival of 5.5 months compared to 3.6 months with docetaxel with a hazard ratio of 0.84. However, in the squamous subgroup, Dato-DXd performed worse with a progression free survival of 2.8 months compared to 3.9 months with docetaxel corresponding to a hazard ratio of 1.32. A similar trend was observed in the overall survival analyses, though confidence intervals crossed 1 in both histology subsets, in this case, the differences observed were not statistically significant. In the nonsquamous subset, the median overall survival was 14.6 months with Dato-DXd and 12.3 months with docetaxel with a hazard ratio of 0.84. In the squamous subset, both arms had shorter survival compared to the nonsquamous subset. The median overall survival with Dato-DXd was almost two months shorter, so 7.6 months, compared to 9.6 months with docetaxel corresponding to a hazard ratio of 1.32. While these analyses suggest the potential survival benefit for Dato-DXd in nonsquamous subset, this trial was not powered to test this hypothesis hence these analyses remain exploratory. Another subgroup analysis of note was the group with actionable genomic alterations. Patients with actionable genomic alterations achieved a median PFS of 5.7 months with Dato-DXD and 2.6 months with docetaxel corresponding to a hazard ratio of 0.35. Similarly, the median overall survival was longer in patients with actionable genomic alterations by almost six months, with a median overall survival of 15.6 months with Dato-DXd and 9.8 months with docetaxel corresponding to a hazard ratio of 0.65. Now, let's talk about safety. Grade 3 or higher treatment related adverse events occurred in 26% of patients with Dato-DXd and 42% with docetaxel. The most common adverse event of any grade seen in the Dato-DXd arm were stomatitis seen in 47% of patients, nausea in 34%, and alopecia in 32%. Treatment related interstitial lung disease occurred in 8.8% of patients on Dato-DXd and 4.1% of patients on docetaxel. Of note, grade 5 drug related ILD was more frequent with Dato-DXd. Seven patients on Dato-DXd and one patient on docetaxel died secondary to drug related ILD in this trial. In summary, TROPION-Lung01 aims to address an unmet need for patients with previously treated non-small cell lung cancer. For this population, the treatment options remain limited with poor survival outcomes. TROPION-Lung01 is a positive trial by design due to clinically modest improvement in PFS. However, the lack of overall survival improvement is disappointing. Exploratory subgroup analyses suggest Dato-DXd may offer survival advantage in specific subsets such as nonsquamous non-small cell lung cancer and patients with actionable genomic alterations. However, these findings require further validation in a prospective trial since TROPION-Lung01 was not designed to address these questions. The data from this trial alone is not sufficient to argue for a change in clinical practice. However, it informs how the future trials using this drug should be tailored. This highlights the importance of studying potential predictive biomarkers earlier in the drug development and incorporating these biomarkers prospectively into the clinical trial designs. Due to the lack of overall survival benefit in this trial, the biologic license application for accelerated approval of Dato-DXd for patients with previously treated nonsquamous non-small cell lung cancer was voluntarily withdrawn. New BLA was submitted for Dato-DXd for patients with previously treated advanced EGFR positive non-small cell lung cancer. This BLA is based on data from TROPION-Lung05, TROPION-Lung01 and TROPION-PanTumor01. Of note, the results of TROPION-Lung05 trial have been just published in JCO. This wraps up today's episode.

The pivotal role of programmed death-ligand 1 (PD-L1) checkpoint inhibition for treating advanced melanoma has been confirmed in findings from the KEYNOTE-006 study comparing the anti-PD-L1 antibody pembrolizumab immunotherapy with the anti-cytotoxic T-lymphocyte associated protein 4 (CTLA-4) drug ipilimumab for treating patients with unresectable advanced or metastatic melanoma. Results from the study were reported at the European Society for Medical Oncology (ESMO) 2024 Annual Congress, held in Barcelona, Spain.
JCO PO author Dr. David R. Gandara at UC Davis Comprehensive Cancer Center, shares insights into his JCO PO article, “Plasma Proteome–Based Test for First-Line Treatment Selection in Metastatic Non–Small Cell Lung Cancer,” one of the Top Articles of 2024. Host Dr. Rafeh Naqash and Dr. Gandara discuss how the PROphet® blood test supports first-line immunotherapy treatment decisions for metastatic NSCLC patients. TRANSCRIPT Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations where we bring you engaging conversations with authors of clinically relevant and highly significant JCOPO articles. I'm your host, Dr. Rafeh Naqash, Podcast Editor for JCO Precision Oncology and Assistant Professor at the OU Health Stephenson Cancer Center at the University of Oklahoma. Today, we are absolutely thrilled to be joined by Dr. David R. Gandara, Professor of Medicine Emeritus, Co-Director of the Center for Experimental Therapeutics and Cancer and Senior Advisor to the Director at UC Davis Comprehensive Cancer Center and also the senior author of the JCO Precision Oncology article entitled “Plasma Proteome–Based Test for First-Line Treatment Selection in Metastatic Non–Small Cell Lung Cancer.” This was one of the top performing articles of 2024, which is one of the reasons why we wanted to bring it in for a podcast discussion. At the time of this recording, our guest's disclosures will be linked in the transcript. David, it is an absolute pleasure to have you today. For somebody like you who's led the field of lung cancer over the years, I'm really excited that you are going to be talking to us about this very interesting article, especially given that I think you're one of the big proponents of liquid biopsies and plasma-based testing. So, for the sake of our listeners - which comprises of academic oncologists, community oncologists, trainees - could you tell us where the biomarker landscape for non-small cell lung cancer is currently, and then we can try to take a deeper dive into this article. Dr. David Gandar: Okay. Well, thank you, Rafeh. It's a pleasure to be with you here today. And I think the current landscape for biomarkers for immunotherapy in non-small cell lung cancer is a mess. There's no better way to describe it. That makes this paper describing a new plasma proteomic assay even more important. So I'll just give you a perspective. There are 14 trials, phase three trials, that were done in first line non-small cell lung cancer advanced stage of immunotherapy versus chemotherapy and some other aspects, although they vary tremendously. Some of them were checkpoint monotherapy, some combined with chemotherapy, some combined with CTLA-4 inhibitors and so forth. 12 out of the 14 were positive, 12 got FDA approval. So there are 12 different options that an oncologist could use. Some of them were squamous cell only, some non-squamous, some used PD-L1 as a biomarker driven part of the study. Some used TMB, tumor mutational burden, some were agnostic. So when you put all of this together, an oncologist can pick and choose among all these various regimens. And by and large, it's PD-L1 that is the therapeutic decision maker. ASCO actually, I think, has done the very best job of making a guideline, and it's, as you well know, called a living guideline, it's dynamic. And it is much easier to interpret, for me and I think for oncologists, than some of the other guidelines. It's got a green light and a red light, it may be kind of orange. And so the green light means this is a strong recommendation by the guideline committee. The orange means it's weak. For this purpose, non-small cell lung cancer, advanced stage, only a very few of the recommendations were green. It's mainly monotherapy and patients with cancers with a PD-L1 over 50%. In our surveys, at our meetings, less than 50% of oncologists in the United States are following these guidelines. Why? Because they don't trust the biomarker. And TMB has the same sort of limitations. They're not bad biomarkers, they're incomplete. They're only looking at a part of the story. So that means we need a new biomarker. And this is one that, I think, the data are quite impressive and we'll discuss it more. Dr. Rafeh Naqash: Absolutely. Like you said, abundance of many therapy options, but not necessarily everything works the same in different subsets of PD-L1 positivity or different subsets of patients with different levels of tumor burden. And like you said, again, difficulty in trying to identify the right biomarker. And that's a nice segue to this PROphet test that you guys ran. So can you tell us a little bit about the plasma proteomic assay? Because to the best of my knowledge, there's not a lot of validated plasma proteomic assays. A lot has been done on the tumor tissue side as far as biomarkers are concerned, but not much on the blood side, except for maybe ctDNA MRD testing. So what was the background for trying to develop a plasma-based proteomic test? And then how did this idea of testing it in the lung cancer setting come into play? And then we can go into the patient population specifics, the cohort that you guys have. Dr. David Gandara: Okay. Well, of course there's a company behind this assay, it's called OncoHost, and I'm a consultant for them. And they came to me two years ago and they said, “We have something different from anyone else.” And they explained the science to me, as well as some other lung cancer experts here in the United States. I'm not a proteomic expert, of course, but they developed an AI machine learning platform to assess plasma proteins in normal people and in people with cancer, and specifically then in people with non-small cell lung cancer. They identified over 7,000 proteins that had cancer implications for therapy, for resistance, for prognosis, etc., and they categorized them based on the literature, TCGA data, etc., and used this machine learning process to figure out which proteins might be most specific for non-small cell lung cancer. And that's where they started. And so out of that 7,000 proteins, where they've identified which ones are angiogenic, which ones are involved with EMT or cell cycle or whatever it might be, they distilled it down to 388 proteins which they thought were worth testing in non-small cell lung cancer. And that's when I became involved. They had a retrospective cohort of patients that had been treated with various immunotherapies. They looked at the analytic validation first, then applied it to this cohort. It looked good. Then they had a very large cohort, which they split, as you usually do with an assay, into a test set and then a validation set. For the test set, they wanted something more than a response. They wanted some indicator of long term benefit because that's where immunotherapy differentiates itself from chemotherapy and even targeted therapy. And so they picked PFS at 12 months. And I became involved at that point and it looked really good. I mean, if you look at the figures in the manuscript, the AUC is superb about their prediction and then what actually happened in the patient. And then in this paper, we applied it to a validation set of over 500 patients in a prospective trial, not randomized, it's called an observational trial. The investigator got to pick what they thought was the best therapy for that patient. And then in a blinded fashion, the proteomic assay experts did the analysis and applied it to the group. And so what that means is some of the patients got chemotherapy alone, some got checkpoint immunotherapy monotherapy, some got in combination with chemotherapy. None of the patients in this study got a CTLA-4 inhibitor. That work is ongoing now. But what the study showed was that this assay can be used together with PD-L1 as what I would call a composite biomarker. You take the two together and it informs the oncologist about the meaning of that PD-L1. I'll give you an example. If that patient has a PD-L1 over 50% in their cancer and yet the PROphet test is negative, meaning less than 5 - it's a 0 to 10 scale - that patient for survival is better served by getting chemotherapy and immunotherapy. However, if the PROphet test is positive and the PD-L1 is over 50%, then the survival curves really look equivalent. As I said earlier, even in that group of patients, a lot of oncologists are reluctant to give them monotherapy. So if you have a test and the same sort of example is true for PD-L1 0, that you can differentiate. So this can really help inform the oncologist about what direction to go. And of course then you use your clinical judgment, you look at what you think of as the aggressiveness of the tumor or their liver metastases, etc. So again, that's how this test is being used for non-small cell lung cancer. And maybe I'll stop there and then I'll come back and add some other points. Dr. Rafeh Naqash: I definitely like your analogy of this therapy de-escalation strategy. Like you mentioned for PD-L1 high where the PROphet test is negative, then perhaps you could just go with immunotherapy alone. In fact, interestingly enough, I was invited to a talk at SITC a couple of weeks back and this exact figure that you're referring to was one of the figures in my slide deck. And it happened by chance that I realized that we were doing a podcast on the same paper today. So I guess from a provocative question standpoint, when you look at the PD-L1 high cohort in the subset where you didn't see a survival difference for chemo plus immunotherapy versus immunotherapy alone, do you think any element of that could have been influenced by the degree of PD-L1 positivity above 50%? Meaning could there have been a cohort that is, let's say PD-L1 75 and above, and that kind of skews the data because I know you've published on this yourself also where the higher the PD-L1 above 50%, like 90% PD-L1 positivity survival curves are much better than 50% to 89%. So could that have somehow played a role? Dr. David Gandara: The first thing to say is that PD-L1 and the PROphet score, there's very little overlap. I know that sounds surprising, but it's also true for tumor mutational burden. There's very little overlap. They're measuring different things. The PD-L1 is measuring a specific regulatory protein that is applicable to some patients, but not all. That's why even in almost all of the studies, people with PD-L1 0 could still have some survival benefit. But in this case they're independent. And not in this paper, but in other work done by this group, the PROphet group, they've shown that the PROphet score does not seem to correlate with super high PD-L1. So it's not like the cemiplimab data where if you have a PD-L1 of greater than 90%, then of course the patient does spectacularly with monotherapy. The other thing that's important here is they had a group of around a little less than 100 patients that got chemotherapy alone. The PROphet score is agnostic to chemotherapy. And so that means that you're not just looking at some prognostic factor. It's actually clinical utility on a predictive basis. Dr. Rafeh Naqash: I think those are very important points. I was on a podcast a couple of days back. I think there's a theme these days we're trying to do for JCO Precision Oncology, we're trying to do a few biomarker based podcasts, and the most recent one that we did was using a tissue transcriptome with ctDNA MRD and you mentioned the composite of the PD-L1 and the PROphet test and they use a composite of the tissue transcriptome. I believe they called it the VIGex test as well as MRD ctDNA. And when your ctDNA was negative at, I believe, the three month mark, those individuals had the highest inflamed VIGex test or highest infiltration of T cells, STING pathway, etc. So are there any thoughts of trying to add or correlate tissue based biomarkers or ctDNA based correlations as a further validation in this research with the company? Dr. David Gandara: Right. So there are many things that are being looked at, various composites looking at the commutations that might affect the efficacy of immunotherapy and how they correlate with profit positivity or negativity. And I'll just give the examples of STK11 and KEAP1. As you know, there's some controversy about whether these are for immunotherapy, whether they're more prognostic or predictive. I'm one of the co-authors among many in the recently published Nature paper by Dr. Skoulidis and the group at MD Anderson which report that for KEAP1 positive especially, but also SDK11 mutated getting immunotherapy, that that's where the CTLA-4 inhibitors actually play the greatest role. So realizing that this is still controversial, there are preliminary data, not published yet, that'll be presented at an upcoming meeting, looking at many of these other aspects, P53, SCK11, KEAP1, other aspects, TMB, that's actually already published, I think in one of their papers. So yes, there's lots of opportunities. The other cool thing is that this isn't a test, it's a platform. And so that means that the OncoHost scientists have already said, “What if we look at this test, the assay in a group of patients with small cell lung cancer?” And so I just presented this as a poster at the world conference in San Diego. And it turns out if you look at the biology of small cell, where neither PD-L1 nor TMB seem to be very important, if you look at the biology of small cell and you form an assay, it only shares 44 proteins out of the 388 with non-small cell. It's a different biology. And when we applied that to a group of patients with small cell lung cancer, again it had really pretty impressive results, although still a fairly small number of patients. So we have a big phase three study that we're doing with a pharmaceutical company developing immunotherapy where we are prospectively placing the PROphet test in a small cell trial. The platform can also be altered for other cancer types. And at AACR, Dr. Jarushka Naidoo presented really impressive data that you can modify the proteins and you can predict immunotherapy side effects. So this is not like a company that says, “We have one test that's great for everything.” You know how some companies say, “Our test, you can use it for everything.” This company is saying we can alter the protein structures using AI machine learning assisted process to do it and we can have a very informed assay in different tumor types and different situations. So to me, it's really exciting. Dr. Rafeh Naqash: Definitely to me, I think, combining the AI machine learning aspect with the possibility of finding or trying to find a composite biomarker using less invasive approaches such as plasma or blood, definitely checks a lot of boxes. And as you mentioned, trying to get it to prospective trials as an integral biomarker perhaps would be likely the next step. And hopefully we see some interesting, exciting results where we can try to match or stratify patients into optimal combination therapies based on this test. So now to the next aspect of this discussion, David, which I'm really excited about. You've been a leader and a mentor to many. You've led ISLC and several other corporate group organizations, et cetera. Can you tell us, for the sake of all the listeners, junior investigators, trainees, what being a mentor has meant for you? How your career has started many years back and how it's evolved? And what are some of the things that you want to tell people for a successful and a more exciting career as you've led over the years? Dr. David Gandara: Well, thank you for the question. Mentoring is a very important part of my own career. I didn't have an institutional mentor when I was a junior investigator, but I had a lot of senior collaborators, very famous people that kind of took me under their wing and guided me. And I thought when I basically establish myself, I want to give back by being a mentor to other people. And you wouldn't believe the number of people that I'm even mentoring today. And some of them are not medical oncologists, they're surgeons, they're radiation oncologists, they're basic scientists. Because you don't have to be an expert in that person's field to be a mentor. It helps, but in other words, you can guide somebody in what are the decision making processes in your career. When is it time to move from this institution onward because you can't grow in the institution you're in, either because it's too big or it's too small? So I established a leadership academy in the Southwest Oncology Group, SWOG. I've led many mentoring courses, for instance, for ISLC, now for International Society Liquid Biopsy, where I'm the executive committee liaison for what's called The Young Committee. So ISLB Society, totally devoted to liquid biopsy, six years old now, we have a Young Committee that has a budget. They develop projects, they publish articles on their own, they do podcasts. So what I'm saying is those are all things that I think opens up opportunities. They're not waiting behind senior people, they are leading themselves. We just, at our International Lung Cancer Congress, reestablished a fellows program where a group of fellows are invited to that Huntington beach meeting. It's now in its 25th year and we spend a day and a half with them, mentoring them on career building. I'll just give you my first, I have the “Letterman Top 10”. So my first recommendation is if all you have is lemons, make lemonade. And what I'm meaning is find what you can do at your institution if you're a junior person, what you can claim to be your own and make the very best of it. But then as you get further along in my recommendations, one of them is learn when to say ‘no'. Because as a junior investigator the biggest threat to your career is saying ‘yes' to everybody and then you become overwhelmed and you can't concentrate. So I'll stop there. But anyway, yes, mentoring is a big part of my life. Dr. Rafeh Naqash: Well, thank you, David. This is definitely something that I'm going to try to apply to my career as well. And this has been an absolute pleasure, especially with all the insights that you provided, not just on the scientific side but also on the personal career side and the mentorship side. And hopefully we'll see more of this work that you and other investigators have led and collaborated on. perhaps more interesting plasma based biomarkers. And hopefully some of that work will find its home in JCO Precision Oncology. Thank you again for joining us today. Dr. David Gandara: My pleasure.

Host Dr. Davide Soldato and Dr. Aaron Mitchell discuss the JCO article "Quality of Treatment Selection for Medicare Beneficiaries With Cancer" TRANSCRIPT 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 Hospital San Martino in Genoa, Italy. Today, we are joined by JCO author Dr. Aaron Mitchell. Dr. Mitchell is a medical oncologist working at Memorial Sloan Kettering Cancer Center where he is also part of the Department of Epidemiology and Biostatistics. Dr. Mitchell specializes in treating genitourinary malignancy and has a research focus on improving how the healthcare system helps people with these and other cancers. So today, Dr. Mitchell will be discussing the article titled, “Quality of Treatment Selection for Medicare Beneficiaries with Cancer.” Thank you for speaking with us, Dr. Mitchell. Dr. Aaron Mitchell: Well, thank you for inviting me. I'm very glad to be here. Dr. Davide Soldato: So I just wanted to introduce the topic by asking a couple of questions, very general, about the background of the article. So basically you reported the data using the SEER-Medicare to assist to assess the determinants of optimal systemic therapies delivery and selection. So, in particular, you focused on individuals that were diagnosed with cancer who were Medicare beneficiaries and in particular were part of the low income subsidy, which is also known as LIS. So I just wanted to ask you if you could briefly explain to our listeners how this program works, and what was the rationale of the study, and if there is any element of novelty in your study compared to what was done before the study was published. Dr. Aaron Mitchell: Yeah. So that's a lot to cover, but yeah, a lot of opportunity to introduce the low income subsidy program which is a very important part of the Medicare program for prescription drugs, but often one that flies under the radar a little bit in the policy discussion. So this subsidy was created synchronously back with the Medicare Part D Program, which was created in 2006. There was some anticipation that for some high cost drugs, not all patients would be able to afford them even with the Part D program insurance as it was being created. And so they created a pathway to give an additional subsidy to some patients who had low income, who were anticipated to being at need and needing that assistance to afford high cost drugs. As the number of high cost drugs has really risen since 2006, this program has played an important role in helping patients afford drugs, especially those who need very expensive cancer drugs. And what this program does is, once you meet the eligibility requirements, which require patients to have both quite a low income. So if you're single, that is at 135% of the federal poverty limit or below, and it also places some restrictions on assets. You also have to have low assets, so low income and low assets in order to qualify for the subsidy. But then once you do, the subsidy is really quite large. Patients who qualify for the LIS at the full subsidy level will pay about $10 per month per drug, even for specialty cancer drugs. So if you think about drugs such as those that we use to treat prostate cancer, my specialty, drugs like enzalutamide or XTANDI that run $15,000 to $20,000 per month, the out of pocket cost for a low income subsidy beneficiary is $10. So that is a huge discount. $10 isn't nothing, but even for someone with a low income, if they've got one or two cancer drugs that are at this rate, it's something that they can often afford. This program applies to Part D cancer drugs that are prescription drugs basically. By and large, these are oral pills that patients are taking on a daily basis at home. These are the drugs that the low income subsidy program applies to. So if a patient needs a drug like that to treat their cancer, then they are able to receive it at very low cost. And what you'll see is a patient- in the studies that have been done, when a patient has low income, low enough for them to be able to qualify for this program, they then have better access to these drugs. You see increased adherence rates, you see increased prescription fill rates. And then when someone, when their income is just high enough to no longer qualify for this program, and they go back to regular Medicare Part D coverage, that's when the problems arise. So it's like as your income moves up the scale, you actually get more problems affording your cancer drugs. So that's the state of the literature so far. And what we realize though, is that all these studies that have looked at the low income subsidy have really focused on just the Part D drugs themselves, the oral drugs. And that's certainly not all of cancer care. There is a growing number of oral drugs, but for many cancers, especially when you're talking about immunotherapy drugs or new systemic radioligand therapies, these are not Part D drugs, these are Part B drugs. And so even if you are low income and you're qualifying for this subsidy, it's not going to help you if you need a Part B drug. Yes, there are certainly a whole host of other programs and different avenues that we can get patients assistance, but some percentage of them, even though they're low income and high need, would not have assistance with a Part B drug. So now, in coming back, the long answer to your question, our rationale was, let's look at these Part D low income subsidy patients and let's see what their access looks like, not just to the oral drugs, but to cancer care writ large. And can we study where they're fitting into the system, not only when they need oral drugs, but when they need any kind of cancer care across the board? Dr. Davide Soldato: So basically, just to summarize, it was an extension of previous literature, but specifically evaluating whether novel regimens that use, for example intravenous drugs, they were covered at the same level and whether there were any inequities in access to cancer treatment under this specific program, which is the LIS. Dr. Aaron Mitchell: Yes, I'd say that's a fair summary. Dr. Davide Soldato: Okay. So more or less, you included 9,000 patients inside of the study and 25% of them were beneficiaries of the LIS program. And you specifically looked at factors that could be associated with not receiving therapies at all, and also whether the quality of care that these patients were receiving were any different compared to those who were not part of the LIS program. So I just wanted to see if you could guide us a little bit in the results, whether you see any kind of differences when we look at access to any type of systemic therapies and whether being a part of the LIS program modified access to the drugs. Dr. Aaron Mitchell: Let me take this opportunity also to highlight a feature of our study that differentiates us a little bit from previous work that's been done. And this is around the specific definition of quality that we use. I know quality is in the title of the manuscript, but I think it's important to emphasize exactly what we mean in this study when we say quality, and it's something very specific. So our measure of quality references back to the NCCN guidelines, which I don't think our audience needs much of an introduction to that. It's the most worldwide recognized standard of care guidelines for oncology practice. And we specifically looked not only at the NCCN guidelines, but at their evidence block scoring system. So what we did was we looked not only at one set of guidelines, but we looked at guidelines across time. We looked at guidelines across our full study period, which was, give or take, 2015-2018, depending on the cancer. And we looked at each point in time to see what was the treatment regimen that was recommended by the NCCN guidelines as being preferred. Some of them make that designation, some of them don't. If there was not a designation of preferred, then we turned to the evidence blocks. And the evidence blocks, we then apply several different measures to kind of rank treatments from those that get high scores for efficacy and safety to those that get low scores for efficacy, safety and the quality of evidence. So we basically come up with a kind of a rank list of the recommended treatments at each point in time. And then we look at the ones that are the highest, we say which are the most highly recommended treatments at any given point in time. That then becomes our definition of quality treatment. And I'm saying this with air quotes, we use the term “optimal treatment” in the study. Did they get that treatment? If there were ties, you could have gotten either of the two treatments that got the equally good score, did you get that treatment versus did you get anything else? So then getting back to our analysis, what we really did was kind of a two-stage study. First, we put all of our patients into our pool, into one big analytic model. And we looked to see what are the factors that predict or are associated with a patient either getting no systemic therapy or any systemic therapy. And then as a second question, we look at the patients who got some form of systemic therapy, and then we ask, again, what percentage of those got the optimal treatment or high quality treatment as opposed to one of the more lowly recommended treatment regimens? So that's how we asked it. We found that patients who were low income subsidy recipients, the low income ones, they were both less likely to receive any systemic therapy. And then even the ones that receive systemic therapy, the ones who made it in the door to see their doctor or their part of the system, they still were less likely to get the optimal treatment that was recommended for their cancer type at the time that they were diagnosed. Dr. Davide Soldato: So basically, even when you are a part of this subsidiary program, you still have a lower access to any type of treatment. And even if you get treatment, you kind of get the ones that were not the preferred according to the NCCN guidelines, or at least they were not scoring as well as those specific regimens. But I think that what our audience might be wondering about is that frequently there are also some other types of characteristics, for example, age or number of comorbidities, which can be associated with having a low socioeconomic status. So I was wondering whether in the analysis you kind of looked specifically also at patient factors, for example, income rather than age or comorbidities, and whether you found any significant association with those and whether it was something that you planned to do in your study. Dr. Aaron Mitchell: Yes. So we looked at many patient factors and those included age and they included the degree of comorbidity. And what we saw with respect to those characteristics was not too surprising. We saw that patients who were older were less likely to receive systemic therapy. We saw that patients who had more comorbidities were also less likely to get systemic therapy. And then across our different designations of treatments, we saw that those patients were also less likely to get the optimal treatment for their cancer. This result though, we would say it certainly needs more study in the future, but it's not immediately concerning. And that is because for patients who have more age, more comorbidity, those often correlate with frailty. And so it could be that these patients aren't getting optimally treated or it could be that their oncologists are just making clinically appropriate decisions about patient selection. We saw as we were doing this work that the treatment regimens that are often getting the highest recommendations from the NCCN, hence, it would become our definition of high quality optimal treatment, are often ones that are aggressive. They're often ones that are multi-drug combinations. They're often ones that it's not just your old antineoplastics, it's the antineoplastics plus an additional immunotherapy or plus a targeted drug. So it's the ones that are more aggressive by and large, and that might be in some cases more than a patient who is older, more frail, could be able to tolerate. And so the oncologist might be making inappropriate judgment to say I'm going to do something a little bit less aggressive here and make an appropriate trade off between anti cancer efficacy and safety. I think we've got kind of a bookmark there and we can look at those trends in the future. So we saw that kind of as expected, and then we turned and looked towards the low income subsidy. And our premise there is, well, your income shouldn't predict what you're getting clinically. In an ideal world, you'd be able to get the appropriate treatment for a patient, and not depend on whether their income is above or below 135% of the poverty limit. So that one seems more like on its face an immediate concern. Dr. Davide Soldato: Thank you very much for the explanation. I was just wondering, did you make some kind of selection when you were analyzing specific diseases or settings where you included just metastatic patients or you also included patients with early stage neoadjuvant treatments? Because I think that it is also very interesting from the perspective of the objectives that we have as oncologists when we are administering systemic treatments. Dr. Aaron Mitchell: Yeah, thank you for bringing that up. That was also one of the goals of our study was to be broad. And we wanted to look for factors, whether it be low income subsidy, whether it be age, socioeconomic background, etc., things that would be broad predictors of outcomes, and by which I mean care delivery outcomes across the board. So not just for, let's say, metastatic breast cancer, but also across any cancer that a patient might walk in the door with, what are the systemic predictors. And so when you mentioned before that our overall cohort is approximately 9,000 patients, that's 9,000 patients split over a variety of what we call clinical scenarios or clinical indications. And that includes multiple solid tumor as well as liquid tumor malignancies. It includes both patients who are initiating systemic therapy with palliative intent for metastatic disease. It also includes several groups of patients who are getting adjuvant therapy. So we want it to be as broad as possible. Our selection of those scenarios was really done with the goal of being as broad as possible and really bringing in everything that we could within the constraints of our data source. And that was really the only limitation that we applied in concept was tumor types that are common enough to have a meaningful sample of patients to analyze. So, one, are there enough patients? And then two, are you able to identify this specific group of patients within SEER-Medicare data? Because when the NCCN divides groups of patients by biomarkers that are not available in SEER-Medicare, we can't really say, “Oh, we're going to study this group of patients.” That would then be one that we have to leave on the side and not include. But everything else where one of those things didn't apply, we tried to include it as best we could. Dr. Davide Soldato: Thank you very much for the explanation. And among the scenarios that you included in the study, were there any striking differences in terms of access to treatment and access to quality treatment the way you define the study? Dr. Aaron Mitchell: Yes, there were differences between these different cancer types, these different cancer indications, but they're not differences that I want to over interpret or read too much into. Certainly, every cancer indication is going to be different, but when we start getting into the individual cancer types, the sample size does get smaller. And we've not done formal tests of comparison or heterogeneity among cancer types. So I don't want to say that the differences which we certainly do see, like numerically, there are differences in the proportion of patients who are getting optimal treatment versus no treatment. I don't want to say that it's because the low income subsidy status or patient age has a bigger impact, let's say for lung cancer than breast cancer. I want to say that is heterogeneity for potential future study when we are able to do a similar follow up analysis with say a larger sample size. I don't want to over interpret those differences at the moment. Dr. Davide Soldato: I was just wondering in case there was anything in particular that you wanted to highlight. But in the end, I think that we also have to acknowledge that the data are based on claims data, observational data. So maybe you're right when you say we should not over interpret this type of difference. And this is just to speculate a little bit, do you think that if you would look at this same specific question in a more contemporary diagnosis frame, like for example, you refer to the fact that most of the diagnoses were between 2016 and 2018. Now that we have more and more of these drugs that would qualify as Part B in the adjuvant or new adjuvant setting, do you think that you would see more differences compared to what you observed in the current study or do you think that it would be more or less the same? Of course this was not part of the analysis that you did, but it's just to have your opinion on the topic in general. Dr. Aaron Mitchell: My expectation would be that since not much has changed with respect to the low income subsidy program from the time period of our study until now, my baseline expectation would be that those results would hold. On the other hand, it is the case that there have been improvements to the standard Medicare Part D benefit since the time of our study. So the low income subsidy patients would be paying the same low out of pocket costs that I mentioned before, about $10 a month give or take, for a specialty cancer drug. But what has started to happen is that for everyone else, their coverage has improved. Because in the US we're in the process of closing, or I think now we finally finished, but you know, a few years lag in claims data, we've closed what used to be called the donut hole, where there was this big coverage gap where patients had to pay a large amount out of pocket for drugs. So there might therefore be a narrowing of the difference, let's say between our low income subsidy participants, the lowest income patients, and then everyone else. But not so much because the low income subsidy status improved or changed, but just because the baseline level of coverage for everyone else may have improved, narrowing that gap. So I'd say that would be very possible. And if your question is more geared towards not so much policy changes, but treatment landscape changes, I would say the big thing that I would maybe guess, and again, this is very much speculation, but you introduce the speculation in TBD on follow up. I think the big change in the landscape has been the broadening indication and uptake of immunotherapy drugs, our PD-1, PD-L1 inhibitors, for a variety of cancer types. And I think the way that that would manifest in our data, were we to repeat it in a more contemporary data set, would be, I think that the access for, let's say, that any systemic therapy among older patients might change. And that is because rather than just having your cytotoxics in hand, the clinical oncologists now know that for many cases there's if not first line therapy, then second line therapy for patients who don't qualify, you can go straight to it, to someone who's not a chemo candidate, you've got a much more tolerable treatment in your back pocket. And so I think that for patients who are more old or more comorbid, we might start to see that a greater proportion of them receive some systemic therapy, it just might not be the cytotoxic agent that is still most highly recommended. It might be, say a single agent, PD-L1 inhibitor, because their oncologist wants to be able to give them something. So I wouldn't be surprised if that gap starts to narrow as well if you're measuring no systemic therapy versus any systemic therapy. Dr. Davide Soldato: And going back to the policy part of the study that you did, do you think that the results of the study that you published in the JCO can better inform policy makers on how to make these treatments more available and be sure that the largest possible proportion of patients gets a systemic treatment and gets the optimal systemic treatment? Dr. Aaron Mitchell: Yes, I do think that this study has some direct and indirect policy implications. I think that our finding is one to highlight the low income subsidy program and maybe help it not to fly under the radar so much anymore. I think all the work that has been done on how much it has helped patients who need oral cancer medications is great, and it shows how beneficial this program can be. We're now shining the light kind of everywhere else and saying, “Okay. That's great. Here's how well it can work when it covers an oral drug, but we've got this group of low income patients who are still at need and they're still very clearly not able to access everything else. When it's not axitinib that they need, it's a pembrolizumab, they're still very much behind the curve and they need some help.” So I think that's one thing just to call attention to this as an ongoing problem. Low income patients, it's not a solved problem yet. It's something that needs further attention. And then for direct policy implications that are on the table, I think we're about to see the Medicare program be able to start negotiating not just Part D drugs, but also in future years, Part B covered drugs and try to lower the price for everyone, both for insurance, both for Medicare itself. And then to the extent that that boils over to the patient's out of pocket responsibility, it'll start to reduce the patient out of pocket costs as well. So I think we can look forward to hopefully an aggressive negotiation program by Medicare to start to directly lower the prices of Part B cancer drugs that these patients are unable to afford. Dr. Davide Soldato: Thank you very much. You did the research you published in the JCO, but you really seem very passionate about the topic of care delivery and quality of care and policy. So I just wanted to ask on a personal note, how did you come to this area of research which is frequently not one that is very cared for by oncologists? It's more frequently something that biostatisticians or public health scientists put their attention to. I just had this curiosity and I wanted to ask you if you could explain a little bit how you came to this area of research. Dr. Aaron Mitchell: Thank you for asking. That's a great question. I'll tell my favorite story about my journey there. I entered medical school planning to be a clinical investigator or maybe even a basic science researcher, and I had some background in that. I went to medical school at NYU where the teaching hospital is Bellevue, which is a large, well known public hospital within New York City. And my eyes started to open regarding the inequities in the system. You always hear about it, you read about the problems in the US healthcare system, but then when you see it on a day to day basis and you can walk four blocks from a private, very well resourced hospital to see a patient with a similar condition four blocks down the road at a under resourced public hospital getting very different treatments and receiving very different outcomes, the injustice in the system really hits you on a visceral level. And it was really, I would say, as soon as I started my clinical rotations in medical school that I realized maybe that's where I can make the most impact with my career and just really fell into it. By the time I was done with medical school, I then knew that I wanted to do something that was in the health policy space. And then by the time I was done with residency, I was like, “Oh, someone had mentioned the words health services research” and the light went on. It's like, “Oh, that's me. That's what I want to do.” Dr. Davide Soldato: Thank you very much. That was a nice story. And I really think that we should all work towards trying to make sure that the inequities inside of the system are eliminated as much as possible. So I think that this concludes our interview for today. So thank you again, Dr. Mitchell, for joining us. Dr. Aaron Mitchell: You're very welcome and thank you so much for your interest.

Dr. Wright discusses key studies regarding medical outcomes in cardiac arrest, surgical patient care, and advanced lung cancer treatment. A GEMMA Network Open study highlights that anterior-posterior defibrillator pad placement improves return to spontaneous circulation in out-of-hospital cardiac arrests compared to anterior-lateral placement, although it did not affect survival rates to hospital discharge. A British Journal of Surgery analysis shows that RN understaffing in England's surgical wards correlates with longer hospital stays and increased risks of conditions like DVT and pneumonia. Lastly, the HARMONY-2 trial, presented at the 2024 World Conference on Lung Cancer, reveals ivanesimab as a promising first-line treatment for PD-L1 positive advanced non-small cell lung cancer, extending progression-free survival significantly more than pembrolizumab.

The approval of Cobenfy highlights Bristol Myers Squibb's deal-making skills and sets the stage for a new generation of treatments for schizophrenia. Other upcoming drugs in the field may further shake up the market. Pharmaceutical companies are continuously working on market strategies to successfully launch new drugs post-FDA approval, as turning a new drug into a successful asset remains a challenge in the

Today, I'm interviewing Dr Anastasia Zekeridou about her article on classical paraneoplastic neurologic disorders, which is part of the August 2024 Continuum issue on autoimmune neurology. Welcome to the podcast, and please introduce yourself to our audience. Dr Zekeridou: Hi. Thank you, Dr Grouse. I'm always excited to talk about paraneoplastic neurological diseases. So, I'm an autoimmune neurologist at Mayo Clinic in Rochester, and I spend my time between the lab and seeing patients in the autoimmune neurology clinic. Dr Grouse: Thank you so much for joining us, and we're really excited to talk about this really important topic. So, to start, I'd like to ask what, in your opinion, is the key message from this article. Dr Zekeridou: That's a good question - there are a lot of messages, but maybe if I can distill it down. For me, one of the first things is that paraneoplastic neurological diseases can actually affect any level of the neuraxis. It can manifest with different types of presentations. If we do suspect a paraneoplastic neurological syndrome, then we need to look for the cancer, and then if we're not certain, even do an immunotherapy trial. A negative antibody does not make for an absence of a paraneoplastic neurological disease (because, often, we depend a lot on them), but you can see patients with paraneoplastic disease that do not have neural antibodies. And then, we always need to be thinking that if we have a paraneoplastic neurological disease, we actually need to be thinking of both the cancer and the immune response together - so, we need to be treating the cancer, we need to be treating the immune response – because, essentially, paraneoplastic neurological syndrome is evidence of this antitumor immune response. So, the main (if I can distill this down in one) is probably that we need to be discussing all of these patients with the treating oncologist, because they have complicated care. Dr Grouse: Great. Thank you so much for that summary. It's very helpful. While many of our listeners are likely familiar with paraneoplastic disorders in their workup (which you've mentioned just now), the concept of neurologic autoimmunity in the context of immune checkpoint inhibitor therapy has more recently become widely recognized. Can you summarize this briefly for our listeners who may be less familiar with this? Dr Zekeridou: I think that we learn more and more about this and we see more and more patients with immune checkpoint inhibitor-related neurological immunity, so, I always think about it in a very straightforward way. So, I think the way we think about immune responses is a balance between tolerance and regulation and immune activations. And then, immune checkpoints are the molecules that help us maintain self-tolerance. So, our immune system - it's probably the best tool that we have to fight against cancer. So, essentially, when we inhibit the immune checkpoints, we actually use our own immune system to fight cancer, but taking the breaks of the immune system essentially can lead to a lot of complications that are immune-mediated. Some of them are neurological - the neurological complications are rare, especially the ones that we need to do something about (so, it's 1% to 4%, in some cases up to 14%), and they do increase when you use multiple immune checkpoint inhibitors together. The main thing for me with the neurological complications is that, sometimes, they are difficult to recognize, they can (again) affect every level of the neuraxis - like, it can be the neuromuscular or the central nervous system (even though neuromuscular complications are much more common than central nervous system complications) - and then a lot of them (the vast majority) will happen within the first three months, but they can also happen even after you stop the immune checkpoint inhibitor. But this three-month interval, it's sometimes useful when you're in a diagnostic silence - it kind of helps you make the decision more towards an immune-related adverse event affecting the nervous system. And then, I think that, practically, once we have diagnosed this patients, we still are not very certain how to treat. All of them will get steroids upfront, but some of them will be difficult to treat, so then, we have to decide on the next treatment depending on evolution. And then, I will just say that (I mentioned it previously, but) these are the patients that the coordination with other subspecialties is one of the main things that we need to do (eg, oncologists) - they often have immune-related adverse events from other systems, so, there is a lot of coordination of care. And, always, the question at the end comes up, Should we be putting these patients back to their immune checkpoint inhibitor cancer immunotherapy that might help them with the cancer? And I think that this is difficult sometimes, and it needs to be decided - most cases - in a case-by-case basis, even though there are some recommendations that I've been discussing in the Continuum article. Dr Grose: That's great, and I encourage everyone to read more about this, because it is a very complex and fascinating topic. On the note of the immune checkpoint inhibitor neurologic dysfunction - I would imagine these are pretty rare - how common are these? And I would suspect they're getting missed a lot - is that correct? Dr Zekeridou: I think it's a very good question. Essentially, what we say for the neurological immune-related adverse events (the ones that we need intervention) - so, they are at least of grade two. (I think that there are less than 4%, mostly, probably close to 1.5%.) There was a study where they used double immune checkpoint inhibitors (so CTLA-4 and PD-1, PD-L1) - they were up to 14%, but this was any grade (so, a little bit of tingling, a little bit of headache), while the ones that we actually need to act upon and we need to actually do something about, they are probably closer to 1.5%. So, are they being missed? I am certain that some of them never make it to the neurologist. So, the ones that we know that we are underestimating is definitely the meningitis - because I think it's more common – but, often, when the patients present, they have something else as well. So, the oncologists will put them on steroids and then they will get better - so, we don't really see them in the neurology clinic (the ones with the very mild side effects). And then, also, these patients are often very sick, and they have a lot of things going for them, so they sometimes do not make it to the diagnosis. Dr Grouse: So then, I want to just take a step back and ask you, what's the most challenging aspect of paraneoplastic neurologic disorders in your opinion? Dr Zekeridou: I think, for me, one of the main things, the classic paraneoplastic disorders - and when I say “classic paraneoplastic disorders”, they are the ones that we think more of with antibodies that are mostly biomarkers of the immune response, and they suggest a cytotoxic T-cell mediated disorder (so, like PCA1 [or anti-Yo] or ANNA-1 [or anti-Hu]) - these patients are very sick often, and we don't have a lot of good treatments for them. And then, even if we treat them, we actually sometimes do not manage to reverse their course - the best that we can do is stabilize. So, I think that this is part of the discussion that we have upfront with these patients - but it is quite challenging, because most of them, we will be giving them a cancer diagnosis ourselves, because we recognize the paraneoplastic neurological syndrome, and we look for the cancer, and then we'll be giving them a cancer diagnosis. And even if we treat their cancer and we treat the immune system, sometimes, then, we don't make a real improvement – like, we stabilize their disease and we sometimes get improvement, but there are cases that we do not and they continue to progress – so, that has been the most challenging aspect of this, and I think that's kind of where we really need more things coming – like, we need more treatments, we need to better understand these diseases and get more straightforward. Dr Grouse: I agree. I think that's absolutely, uh, what we all hope for these types of disorders, and I can imagine we all can remember at least one case just like this where someone had this type of problem and just didn't respond to treatment. So, strong hopes that there will be improvement with this in the years coming. Another question I have for you is, what in your article do you think would come as the biggest surprise to our listeners? Dr Zekeridou: I think that, because we discussed that immune checkpoint inhibitors (maybe we don't know as well), so one of the main things for me is when we first started thinking of neurological complications of immune checkpoint inhibitors, there was a lot of myasthenia gravis mentioned (patients presenting with myasthenia gravis), and then some of them antibody-positive, some of them antibody-negative. Now, with the time that has passed by, we recognize that myasthenia gravis is very rare. Like, I've seen tons of patients (probably more than that, actually) – and then, maybe I've seen one patient with de novo myasthenia gravis. We realize that the immune checkpoint inhibitor myasthenia gravis that we were thinking of are – they're mostly the immune checkpoint inhibitor myocytes cases - so, then, this is one of these myopathies that looks like no other. So, it really has a very predominant oculobulbar involvement (that's why everybody was thinking that this is myasthenia gravis), but, practically, the EMGs are negative, the patients do not respond to pyridostigmine - so, practically, these are really myopathy cases. And why is that important? Because 30% to 40% of these cases might also have a cardiomyopathy, for example, and then we're putting all these patients on pyridostigmine and medications that they do not necessarily need. So, I think one of the chains in concepts that we have in the later years is that, really (and this is one of the most common immune-related adverse events that we see in our clinic), that these patients with ICI myositis really present with the oculobulbar involvement and proximal involvement that we can see in myasthenia, but they do not have a neuromuscular junction problem. Dr Grouse: Now, we've all struggled with identifying a primary malignancy in patients where a paraneoplastic syndrome was strongly suspected. Do you have any tips on how to make this workup as high yield as possible? Dr Zekeridou: Yeah, I think that's a difficult question. I think it depends a little bit on your patient as well. So, if you have an antibody that makes things easier (and we can discuss about that, but), practically, for me, a patient that I have a high suspicion, that we get a CT chest, abdomen, and pelvis upfront - and often, we don't get PET scans, right, directly, because we have insurance companies maybe playing a role in what we would do. So, I would get this for a woman - she has to have a mammogram. For a man, they have to have a testicular ultrasound. That's the basics for me. And then, when we see more younger women or when we suspect an MDA, then they will need to have the ultrasound to look for the ovarian teratomas or an MRI of the abdomen - so, the PET scan for me, if I have a high suspicion, it will always be the next step. Like, we have increased diagnostic yield with PET scans, but we also need to remember, what are the tumors that you will not find on a PET scan? Teratomas are not PET-avid, and, often we say, “Oh, we found the lesion in the ovary and the PET scan was negative.” That doesn't matter. In an NMDA-receptor antibody patient, if you find the lesion in the ovary, you need to make certain it's not a teratoma, because PET scans will not necessarily pick up a teratoma - it's not an avid malignancy. So, if the patient is a smoker and I suspect small-cell lung cancer, so I would always get the PET scan. If I have a patient with a high-risk antibody like PCA1 (or anti-Yo) and I didn't really find the tumor with the CT chest, abdomen, and pelvis and the mammogram, I will always get the PET scan. Same for the patients with the smoking history. I will also say that, sometimes, we forget other malignancies. So, for example, we have neuronal intermediate filament antibodies (so, ANNA-3 antibodies), and some of them will have Merkel cell. So, depending on the patient, on the antibody, and if we didn't find anything else, I would do a skin check. If they have GI symptoms, I would look for the GI tumor as well. So, even though the basics are what I mentioned, I will adapt depending on the patient symptoms. And all of these patients should have age-appropriate cancer screening, so if they didn't have a colonoscopy, they will have to have a colonoscopy. So, this is part of the main things. And then, the question for me that always comes up is, “Who is the person that you're going to keep on repeating the screen?” And then, practically, if you have a low-risk paraneoplastic antibody that comes (let's say LGI1), we know it's a low risk, so I would actually do the cancer screening - I will look for the thymoma once, and then that would be it. But if you have a patient with a high-risk paraneoplastic antibody (let's say ANNA-1 [or anti-Hu] or anti-Yo [anti-PCA1]), these are the patients that I will keep on screening - and then I will do every four to six months for two years (that's the current recommendation), but I will probably continue yearly after. And then, we need to also remember that whenever you have a neurological relapse, that's exactly when you need to be looking for the cancer as well - so, you must be thinking that the idea is that maybe you have the immunological relapse because there is cancer somewhere. So, these are the types of things that I kind of adapt to specific patients. But I think when we're not certain, broad screening is what we need. And then, again, the PET scan - for me, it's a great test, but we need to know its limitations. So, that's the other thing that comes up a lot in the phone calls or in the patients that I see that we do a PET scan - but practically, it's not good for some of the malignancies that we're looking for. Dr Grouse: That's really great to point out, and I'm glad you brought up the risk level of the particular syndrome. You have a great table in your article that summarizes the risk level of some of the various syndromes - so, you know, just a reminder for everyone to check that out if you want to have more information about this and how this applies to the screening - so very helpful. What is the easiest mistake to make, and also maybe to avoid, when treating patients with paraneoplastic neurologic disorders? Dr Zekeridou: That's a great question, actually. So, there are two things here. One is that we need to be thinking about paraneoplastic neurological syndromes, because if you don't think about them, then you don't look for them. So that's the one thing. So, patients that come with a subacute onset of neurological dysfunction - they have systemic features, or they are smokers, they have autoimmunity in the family (all those things) – like, we need to be thinking about paraneoplastic neurological syndromes. On the other side, we also see a little bit more of overdiagnosis that's coming in the later years. So, one of the things that we see a lot is that we kind of have difficulties with the interpretation of the neural antibodies - so, sometimes, we will get a neural antibody, and then it will not fit, but we will base our diagnosis on the neural antibody presence. And then, some neural antibodies are great - we don't really see false-positives - but some of them are not great and we do see false-positives. So, for me, the main thing that I would say is that we need to have a clinical suspicion - we're treating the patient and the clinical syndrome if it is compatible with a paraneoplastic neurological disorder, and then the neural antibodies are the ones that are going to help us, like, diagnose or point to a cancer - but we are really treating the patient. And then, if we give a treatment and it doesn't make sense how the patient evolves, we actually need to reassess the diagnosis, because we do have both overdiagnosis, but also we have underdiagnosed in patients that it's not suspected - so I think it's kind of the increased awareness that helps, but we also need to be going back always to the clinical manifestations of the patient. Dr Grouse: Really great points to make, and thank you so much for that. What is the most common misconception you've encountered in treating patients with paraneoplastic disorders? Dr Zekeridou: So, one of the things that we see a lot is that patients wait to be treated - even with high suspicion of paraneoplastic neurological syndromes - until we have the neural antibodies, and sometimes, if the neural antibodies are negative, we have patients that are not given a paraneoplastic neurological syndrome or autoimmune neurological syndrome diagnosis because of the negativity of the antibodies. So, for me, one of the main things is that the patients actually fit clinically with a paraneoplastic neurological syndrome - and there are scores that can help us, clinical manifestations that can actually help us make this diagnosis. We need to be looking for the cancer and treating them, regardless of the presence of the antibody. Some patients will not have the antibodies for weeks. The second aspect to this is that, often, we want to say, “Oh, it's a paraneoplastic neurological syndrome. They will treat the cancer and, like, that's the oncologist's job.” But, practically, I think that the neurologist will really need to be involved with this. I think the patients need treatment of the immune response and treatment of the tumor. So, I think we are part of the treatment team for these patients and it's not only the oncologists that are treating the tumor. Dr Grouse: Where do you think the next big breakthrough in this area will be? Dr Zekeridou: Where I hope it would be - and I'm hoping that it's actually what it is going to be – is, really, better understanding and treating the classic paraneoplastic neurological diseases, that they are T-cell mediated disorders that lead to neural cell distraction, and we don't have good treatments for these patients and we cannot get any improvement. So, there is a lot of research going on there. How can we prevent? How can we treat? But, I think that would be the next big milestone for us, because the antibody-mediated diseases - so we now have a lot of good treatments. Like NMDA-receptor encephalitis, AMPAR encephalitides - these antibody-mediated disorders, we have good treatments. The disorders that the antibodies are biomarkers - and they are the cytotoxic diseases, the effectors of the autoimmunity - we don't. So, that's where I hope and think our breakthrough will be. Dr Grouse: Definitely hoping to see more advancements in this area and already, I think, very quickly developing field. So, I wanted to talk a little bit more about you and what brought you to this area of neurology I think which most of us find to be a very fascinating field that would love to hear more about what brought you to it. How did you become interested in this area of neurology? Dr Zekeridou: I did my medical school in Greece. So, in Greece, towards the end of the sixth year, you need to decide what your specialty would be, and for the life of me, I could not decide between oncology and neurology - I was changing my mind all the time. And then, I decided that the diagnosis is more important to me in terms of a physician - that's why I went more with neurology and I was clear on my choice. So, practically, then, I went and did my residence in Switzerland, and something happened and I found myself in the outpatient autoimmune neurology multiple sclerosis clinic for a year, and it was evident to me that this is my passion. Like, the multiple sclerosis, I thought was a great disease, but it was the cases that they were not multiple sclerosis, that they were the ones that they were the most fascinating for me. So, then, I did my peripheral nerve year - so even more, it was clear for me that this is the immune system interactions, the cancer, and the neurological symptoms - that's what I wanted to do. And practically, I pursued a fellowship in Lyon in the French Reference Center for Paraneoplastic Diseases, and I was sold. There was nothing else for me. So, eventually I came here at Mayo (and then I stayed) - but it was very clear, even since the beginning - and I really found something that combined both of my passions even from medical school. Dr Grouse: What are you most excited about in this field? And, specifically, you know, what might you impart to other trainees who are thinking about choosing this field for themselves? Dr Zekeridou: So, I think that there are many things. So, autoimmune neurology or paraneoplastic neurological syndromes, they can affect every level of the neuraxis, so, practically, your clinician, that we see everything - we'll see central nervous system, peripheral nervous system, neuromuscular junction – so, that's actually very fascinating for me. The second part of it is that we have diseases that we can actually treat. We see differences in patients that we will intervene and we will really change their disease course. And the other thing for me is all the research that is ongoing. So, practically, the research in paraneoplastic syndromes or neurological immunity is directly translational to the patient - like, we have kind of a bed-to-bedside type of research that is going on. And basic research is important and there is a lot of advances, but you can see them directly, like, being translated in patients - so, essentially, the research is directly translational to clinic, and that makes it very exciting. Dr Grouse: I think that your excitement about this field is very inspirational and will hopefully inspire many future trainees who are interested in this field. So, when you're not learning more about paraneoplastic syndromes and their treatment and diagnosis, what else do you like to do? Tell us something about your outside interests. Dr Zekeridou: So, again, I come from a very diverse background and the way that I arrived in the states, but, I really like traveling. So, we would travel a lot lately. We travel more in Greece, because when you're coming from Greece and you're not living there, your summers are always there - but we try to explore different places there. And one of my main things and passions that I like is, essentially, cooking. So that relaxes me, that helps me - cooking and having friends over – so, that's my favorite thing of doing outside of work. Dr Grouse: Well, I have to say it's hard right now to imagine anything more fun than traveling and enjoying good food and Greece. So, I think your hobby seems like one we can all get behind. Dr Zekeridou: It's relaxing the mind. Dr Grouse: Yes, yes. This has been a really great discussion on what I think is a very interesting area of neurology, and we really appreciate you taking the time to talk with us today. Dr Zekeridou: Thank you so much for having me. It was great talking to you.

Dr. Allison Zibelli and Dr. Erika Hamilton discuss the results of the DESTINY-Breast06 trial in HR+, HER2-low and HER2-ultralow metastatic breast cancer and the A-BRAVE trial in early triple-negative breast cancer, the results of which were both presented at the 2024 ASCO Annual Meeting. TRANSCRIPT Dr. Allison Zibelli: Hello, I'm Dr. Allison Zibelli, your guest host of the ASCO Daily News Podcast. I'm an associate professor of medicine and breast medical oncologist at the Sidney Kimmel Cancer Center of Jefferson Health in Philadelphia. My guest today is Dr. Erika Hamilton, a medical oncologist and director of breast cancer research at the Sarah Cannon Research Institute. We'll be discussing the DESTINY-Breast06 trial, which showed a progression-free advantage with the antibody-drug conjugate trastuzumab deruxtecan (T-DXd) compared to chemotherapy in hormone receptor-positive HER2-low or HER2-ultralow metastatic breast cancer. We'll address the implications of this study for the community, including the importance of expanding pathology assessments to include all established subgroups with HER2 expression, and the promise of expanding eligibility for antibody-drug conjugates. We'll also highlight advances in triple-negative breast cancer, focusing on the A-BRAVE trial, the first study reporting data on an immune checkpoint inhibitor avelumab in patients with triple-negative breast cancer with invasive residual disease after neoadjuvant chemotherapy. Our full disclosures are available in the transcript of this episode. Erika, it's great to have you on the podcast today. Dr. Erika Hamilton: Thanks so much, Allison. Happy to join. Dr. Allison Zibelli: Antibody-drug conjugates are rapidly changing the treatment landscape in breast cancer. The data from the DESTINY-Breast06 trial suggests that trastuzumab deruxtecan may become a preferred first-line treatment option for most patients with HER2-low or HER2-ultralow metastatic breast cancer after progression on endocrine therapy. First, could you remind our listeners, what's the definition of HER2-ultralow and what were the findings of this trial? Dr. Erika Hamilton: Yeah, those are fantastic questions. Ultralow really has never been talked about before. Ultralow is part of a subset of the IHC zeros. So it's those patients that have HER2-tumor staining that's less than 10% and incomplete but isn't absolutely zero. It's even below that +1 or +2 IHC that we have classified as HER2-low. Now, I think what's important to remember about D-B06, if you recall, D-B04 (DESTINY-Breast04) was our trial looking at HER2-low, is that D-B06 now included HER2-low as well as this HER2-ultralow category that you asked about. And it also moved trastuzumab deruxtecan up into the frontline. If you recall, D-B04 was after 1 line of cytotoxic therapy. So now this is really after exhausting endocrine therapy before patients have received other chemotherapy. And what we saw was an improvement in progression-free survival that was pretty significant: 13.2 months versus 8.1 months, it was a hazard ratio of 0.62. And you can ask yourself, “well, was it mainly those HER2-low patients that kind of drove that benefit? What about the ultralow category?” And when we look at ultralow, it was no different: 13.2 months versus 8.3 months, hazard ratio, again, highly significant. So I think it's really encouraging data and gives us some information about using this drug earlier for our patients with hormone receptor-positive but HER2-negative disease. Dr. Allison Zibelli: I thought this study was really interesting because it's a patient population that I find very difficult to treat, the hormone receptor-positive metastatic patient that's not responding to endocrine therapy anymore. But it's important to mention that T-DXd resulted in more serious toxicities compared to traditional chemotherapy in this study. So how do you choose which patients to offer this to? Dr. Erika Hamilton: Yeah, those are both great points. So you're right, this is after endocrine therapy. And in fact, about 85% of these patients had received at least 2 prior lines of endocrine therapy. So I have some people kind of asking, “Well, if endocrine therapy really isn't benefiting everyone in the second-line setting post-CDK, should we just move to the ADCs?” And, no, probably we should really make sure that we're exhausting endocrine therapies for those patients that are going to benefit. And once we determine somebody has endocrine-resistant disease, that's when we would think about switching. In terms of the side effects, I think you're right. It's mainly ILD that's probably the more serious side effect that we worry about a little bit with trastuzumab deruxtecan. The good news is, through multiple trials, we've gotten a little bit better at managing this. We've pretty much all but eliminated any fatal cases of ILD, definitely less than 1% now. ILD rates, depending on what study you look for, kind of ranges in that 10% to 15% range. Any grade ILD on D-B06 was 11.3%. So really kind of making sure that we look for ILD at scans, making sure that patients are educated to tell us about any new pulmonary symptoms: cough, exertional dyspnea, shortness of breath at rest, etc. But I think the most common side effects that we really deal with on a daily basis with trastuzumab deruxtecan, luckily, is nausea, which we've gotten better at managing with the 2- or 3-drug antiemetic regimen, and probably a little bit of fatigue as well. Dr. Allison Zibelli: Thank you. So, I think for most people in the community, the sticking point here will be expanding pathology assessments to include all of the subgroups, including the ultralow. Most patients in the community are not testing for HER2-low and HER2-ultralow now. Dr. Erika Hamilton: Historically, we kind of all did HER2 IHC, right? And then as FISH became available, there were a lot of institutions that moved to FISH and maybe didn't have IHC anymore. And now, at least in my institution, we do both. But I think it's a very important point that you made that IHC was really designed to pick out those patients that have HER2-high, the 3 pluses or the FISH amplified cases. It was not to tell the difference between a 1+ or a 2+ or a 0 that's not quite a 0 and a 1+. So I think you're right. I think this is tough. I probably have a little bit more of an interesting take on this than some people will. But data from ASCO, not this year but in 2023, there was actually a pretty eloquent study presented where they looked at serial biopsies in patients, and essentially, if you got up to 4 or 5 biopsies, you were guaranteed to have a HER2-low result. Now, this didn't even include ultralow, which is even easier. If we know we include ultralow, we're really talking about probably 85% to 90% of our patients now that have some HER2 expression. But if we biopsy enough, we're guaranteed to get a HER2 low. And so I think the question really is, if we know IHC wasn't really designed to pick out these ultralows, and we know kind of greater than 90% of patients are going to have some expression, did we kind of develop this drug a little bit backwards? Because we thought we understood HER2, and the reality is this drug is a little bit more like a sacituzumab govitecan, where we don't test for the TROP2. Should we really be kind of serial biopsying these patients or should maybe most patients have access to at least trying this drug? Dr. Allison Zibelli: So I don't think that most of my patients will really be happy to sign up for serial biopsies. Dr. Erika Hamilton: Agreed. Dr. Allison Zibelli: Do we have any emerging technologies for detecting low levels of HER2? You talked about how the IHC test isn't really designed to detect low levels of HER2. Do you think newer detection techniques such as immunofluorescence will make a difference, or will we have liquid biopsy testing for this? Dr. Erika Hamilton: Yeah, I think liquid biopsy may be a little bit hard, just because some of those circulating tumor cells are more of a mesenchymal-type phenotype and don't necessarily express all of the same receptors. Normally, if they're cytokeratin-positive, they do, but certainly there is a lot out there looking at more sensitive measures. You mentioned immunofluorescence, there are some even more quantitative measures looking at lower levels of HER2. I definitely think there will be. I guess, ultimately, with even the IHC zeros that are the less than 10% incomplete staining, having a PFS that was absolutely no different than the HER2 low, I guess the question is, how low can we really go? We know that even the IHC zeros doesn't mean that there's no HER2 expression on the cell surface. It just means that maybe there's a couple of thousand as opposed to 10,000 or 100,000 copies of HER2. And so it really appears that perhaps this drug really is wedded to having a lot of HER2 expression. So ultimately, I wonder how much we're going to have to use those tests, especially with what we know about tumor heterogeneity. We know that if we biopsy 1 lesion in the liver, biopsy a lymph node, or even another lesion in the liver, that the HER2 results can have some heterogeneity. And so ultimately, my guess is that most people have some HER2 expression on their breast cancer cells. Dr. Allison Zibelli: So maybe we're going to be using this for everybody in the future. Dr. Erika Hamilton: It certainly seems like we keep peeling back the onion and including more and more patients into the category that are eligible to receive this. I agree. Dr. Allison Zibelli: Let's move on to triple-negative breast cancer, namely the A-BRAVE trial. This was an interesting trial for patients that did not get neoadjuvant immunotherapy and testing 2 groups. The first group was those with residual disease after neoadjuvant conventional chemotherapy. The second group was people with high-risk disease identified upfront that had upfront surgery. The study found that adjuvant avelumab did not improve disease-free survival versus observation, which was the study's primary endpoint. But interestingly, there was a significant improvement in 3-year overall survival and distant disease-free survival. Can you give us your thoughts on that? Dr. Erika Hamilton: Yeah, I think this study was really interesting. Right now, the standard for our patients with larger or node-positive triple-negative cancers is KEYNOTE-522. It's a pretty tough regimen. It's kind of 2 sequential uses of 2 chemotherapies, so 4 chemotherapy agents total with pembrolizumab. But you're right, this study looked at those that had residual disease after neoadjuvant that didn't include immunotherapy, or those patients that didn't get neoadjuvant therapy, went to surgery, and then were receiving chemotherapy on the back end. I'm going to give you the numbers, because you're right. The 3-year disease-free survival rates were not statistically significant. It was 68.3% among those that had avelumab, 63.2% with those that had observation only. So the difference was 5.1% in favor of avelumab, but it wasn't statistically significant. A p value of 0.1, essentially. But when we looked at the 3-year overall survival rates, we saw the same pattern, those patients with the avelumab doing better, but it was 84.8% overall survival and not, unfortunately, dying, versus 76.3%. So the magnitude of benefit there was 8.5%, so about 3% higher than we saw for disease-free survival, and this was statistically significant. So is this going to change practice for most patients? I probably don't think so. I think for our patients that have larger tumors that's recognized upfront or have node positivity, we're probably going to want to use neoadjuvant chemo. Being able to get a PCR is very prognostic for our patients and enables us to offer things on the back end, such as PARP inhibitors or further chemotherapy of a different type of chemotherapy. But for our patients that go to surgery and maybe the extent of their disease just isn't recognized initially, this could be an option. Dr. Allison Zibelli: I agree. I think this will be a really useful regimen for patients where we get the surprise lymph node that we weren't expecting, or somebody who comes to us, maybe without seeing the medical oncologist, who got upfront surgery. So I thought this was really interesting. What kind of translational studies do you think we're going to do to try and understand which patients would benefit from avelumab? Dr. Erika Hamilton: Yeah, I think that's a great question, and honestly, it's a question that we haven't really answered in the neoadjuvant setting either. Immunotherapy in breast cancer is just a little bit different than it is in some other diseases. We have a benefit for those patients that are PD-L1 positive in the first line. We really haven't seen benefit for metastatic outside of first line. And then in neoadjuvant, it was among all comers. We don't have to test for PD-L1. And now we have this avelumab data from A-BRAVE. I think the question is, is there's probably a subset of patients that are really getting benefit and a subset that aren't. And I don't know that PD-L1 testing is the right test. We know a lot of people are looking at TILs, so kind of lymphocytes that are infiltrating the tumor, a variety of other kind of immunologic markers. But my guess is that eventually we're going to get smart enough to tease out who actually needs the immunotherapy versus who isn't going to benefit. But we're not quite there yet.

Immunotherapy is a type of novel cancer therapy that leverages the body's own immune system to target cancer cells. In this episode, we focused on the most common type of immunotherapy: immune checkpoint inhibitors or ICIs. ICIs are monoclonal antibodies targeting immune “checkpoints” or brakes to enhance T-cell recognition against tumors. ICI has become a pillar in cancer care, with over 100 approvals and 5,000 ongoing trials. ICIs can lead to non-specific activation of the immune system, causing off-target adverse events such as cardiotoxicities. ICI-related myocarditis, though less common, can be fatal in 30% of cases. Clinical manifestations vary but can include chest pain, dyspnea, palpitations, heart failure symptoms, and arrhythmias. Diagnosis involves echocardiography, cardiac MRI, and endomyocardial biopsy. Treatment includes high-dose corticosteroids with potential additional immunosuppressants. Baseline EKG and troponin are recommended before ICI initiation, but routine surveillance is not advised. Subclinical myocarditis is a challenge, with unclear management implications. So let's dive in and learn about cardiotoxicity of novel immunotherapies with Drs. Giselle Suero (series co-chair), Evelyn Song (episode FIT lead), Daniel Ambinder (CardioNerds co-founder), and Tomas Neilan (faculty expert).

Pearls and Quotes - Cardiotoxicity of Novel Immunotherapies Immune checkpoint inhibitors (ICI) play a crucial role in current oncology treatment by enhancing T-cell recognition against tumors. ICI-related cardiac immune-related adverse events (iRAEs) include myocarditis, heart failure, stress-cardiomyopathy, conduction abnormalities, venous thrombosis, pericardial disease, vasculitis, and atherosclerotic-related events. ICI myocarditis can be fatal; thus, prompt recognition and treatment is crucial. Management includes cessation of the ICI and treatment with corticosteroids and potentially other immunosuppressants. Close monitoring and collaboration with cardiology and oncology are crucial. Rechallenging patients with immunotherapies after developing an iRAE is controversial and requires careful consideration of risks and benefits, typically with the involvement of a multidisciplinary team. Show notes - Cardiotoxicity of Novel Immunotherapies What are immune checkpoint inhibitors (ICIs)? ICIs are monoclonal antibodies used to enhance the body's immune response against cancer cells. Currently, there are four main classes of FDA-approved ICIs: monoclonal antibodies blocking cytotoxic T lymphocyte antigen-4 (CTLA-4), programed cell death protein-1 (PD-1), lymphocyte-activation gene 3 (LAG3), and programmed cell death ligand-1 (PD-L1). ICIs can lead to non-specific activation of the immune system, potentially causing off-target adverse events in various organs, including the heart, leading to myocarditis. The mechanisms of cardiac iRAEs are not fully understood, but they are believed to involve T-cell activation against cardiac antigens, which leads to inflammation and tissue damage. What are the cardiotoxicities related to ICI therapies? ICI-related cardiac immune-related adverse events (iRAEs) include myocarditis, heart failure, stress-cardiomyopathy, conduction abnormalities, venous thrombosis, pericardial disease, vasculitis,
