Podcasts about tkis

Next-generation anti-VEGF agents are designed for durability. But does that actually change the rate at which they're administered? David Miller, MD, joins us to review a pair of ARVO 2025 presentations that examined his clinic's real-world administration patterns for bevacizumab (Avastin, Genentech), faricimab (Vabysmo, Genentech/Roche), and high-dose aflibercept (Eylea HD, Regeneron). What were the differences—and did they really matter?  Also, Robert Wang, MD, helped us understand the state of play in the TKI pipeline as he shared data from the phase 2b ODYSSEY study. What are the latest data on CLX-AX (Clearside Biomedcial)? And where does it stack up against the other TKIs in the pipeline? Stick with us to find out. 

This is the second episode of a two-part series on the HER2 diagnostic and treatment landscape in non-small cell lung cancer (NSCLC), hosted by the Oncology Brothers, Drs Rohit and Rahul Gosain.      In this episode, Dr Isabel Preeshagul and Dr Eric Singhi provide the benefit of their experience when discussing how to approach different treatment scenarios in HER2-mutant NSCLC.   The conversation unfolds to cover: • Ways to distinguish HER2 alterations from other alterations on biomarker reports  • The latest efficacy and safety data of currently approved and emerging treatments for HER2-altered NSCLC   • The potential CNS activity of these treatments in patients with HER2-mutated NSCLC  • How the treatment pathway may look in the near future      Clinical takeaways • In NSCLC, HER2-positivity includes mutations, amplifications and overexpression. It's important to distinguish HER2 alterations from EGFR mutations, particularly exon 20 insertions, when interpreting next-generation sequencing (NGS) results  • Trastuzumab Deruxtecan (T-DXd) is currently the only approved targeted agent for HER2-altered NSCLC in the 2nd-line setting. It shows promising efficacy, especially in HER2-mutant cases, but has limited brain penetration and is associated with notable side effects, including pneumonitis, which requires close monitoring  • Emerging TKIs, such as zongertinib, BAY 2927088 (sevabertinib), and NVL-330, target HER2-mutations and have shown high response rates and CNS activity in early studies, without ILD/pneumonitis. These treatments come with unique side effects like diarrhoea and rash, which can be managed with supportive care  • CNS metastases are common, with up to 30% of HER2-altered NSCLC patients presenting with or quickly developing CNS metastases. Current large molecule therapies (like T-DXd) have limited brain penetration, making small-molecule TKIs, like zongertinib, BAY 2927088 (sevabertinib), and NVL-330, promising for their potential CNS activity • Current standard 1st-line care for HER2-mutant NSCLC remains platinum-based chemotherapy ± immunotherapy. Targeted agents (like T-DXd) are generally reserved for 2nd-line use, but ongoing trials are evaluating the move toward frontline therapy Follow us on social media: •⁠  ⁠X/Twitter: https://twitter.com/oncbrothers •⁠  ⁠Instagram: https://www.instagram.com/oncbrothers •⁠  Website: https://oncbrothers.com/ Don't forget to subscribe for the next episode

Dr. John Sweetenham and Dr. James Foran discuss the evolving treatment landscape in acute myeloid leukemia, including new targeted therapies, advances in immunotherapy, and the current role for allogeneic transplantation. TRANSCRIPT Dr. John Sweetenham: Hello, I'm Dr. John Sweetenham, the host of the ASCO Daily News Podcast. There has been steady progress in the therapies for acute myeloid leukemia (AML) in recent years, largely based on an increasing understanding of the molecular mechanisms which underlie the disease. On today's episode, we'll be discussing the evolving treatment landscape in AML. We'll explore risk group stratification, new targeted therapies, advances in immunotherapy for AML, and also a little about the current role for allogenic transplantation in this disease.  I'm delighted to welcome Dr. James Foran to this discussion. Dr. Foran is a professor of medicine and chair of the Myeloid Malignancies and Blood and Marrow Transplant Disease Group at the Mayo Clinic Comprehensive Cancer Center. He's based in Jacksonville, Florida.  Our full disclosures are available in the transcript of this episode.  James, it's great to have you join us on the podcast today, and thanks so much for being here. Dr. James Foran: I'm delighted and thank you for the invitation. Thank you very much. Dr. John Sweetenham: Sure, James, let's get right into it. So, our understanding of the molecular mechanisms underlying AML has resulted not only in new methods for risk stratification in this disease, which have added refinement to cytogenetics, but also has resulted in the development of many new targeted agents. Understanding that this is a complex area of investigation, and our time is somewhat limited, can you give us a high-level update on the current state of the art in terms of how risk factors are being used for treatment selection now? Dr. James Foran: Absolutely. I think in the past, you know, we had things broken down pretty simply into make a diagnosis based on morphology, do cytogenetics, break patients into the groups of those who were more likely to benefit from therapy – so-called favorable risk – those where the intensive therapies were less likely to work – so-called poor adverse risk, and then this large intermediate group that really had variable outcomes, some better, some worse. And for a long time, the progress was in just identifying new subtle cytogenetic risk groups. And then, late 1990s, we began to understand that FLT3 mutations or NRAS mutations may be more adverse than others that came along. In the first part of this millennium, in the, you know, 2000-2010 range, a lot of work was being done to understand better or worse risk factors with single genes. The ability to do multiplex PCR, and then more recently NGS platforms, have allowed us to really look at many genes and identify many mutations in patients. At the beginning that was used just to sort of refine – who did a little better, who did a little worse with intensive therapy – helped us decide who may benefit more from an allogeneic transplanter for whom that would not be necessary.  But the good news is that really, we're now starting to target those mutations. One of the first molecularly targeted treatments in leukemia was FLT3 mutations, where we knew they were adverse. Then along came targeted treatments. I was involved in some of those early studies looking at sunitinib, sorafenib, more recently midostaurin, now quizartinib, FDA approved, and gilteritinib in the relapse refractory setting.  So we're moving into a state where we're not just refining prognosis, we're identifying targets. You know, it's been slow progress, but definite incremental progress in terms of outcomes by looking for FLT3 mutations, then looking for IDH mutations, and more recently, mutations involving NPM1 or rearrangement of what we used to call the MLL gene, now the lysine methyltransferase 2A or KMT2A rearrangement, where we now have targets. And it's not just for refinement of prognosis, but now we're identifying therapeutic targets for patients and ways to even look for measurable residual disease which is impacting our care. Dr. John Sweetenham: That's great, James. And I'm going to expand on that theme just a little bit and perhaps ask you to elaborate a little bit more on how the introduction of these new therapies have specifically impacted frontline therapy. And a couple of ancillary questions maybe to go along with that: First of all, is ‘7+3' a standard therapy for anybody in 2025? And maybe secondly, you know, could you comment also maybe briefly on older patients with AML and how you think maybe the treatment landscape is changing for them compared with, say, 5 or 10 years ago? Dr. James Foran: I'll start with the therapy and then work my way back. So we've had ‘7+3' cytarabine daunorubicin or cytarabine anthracycline since 1976, and we're still using it as the backbone of our intensive therapy. There is still an important role for it, particularly in younger or fitter patients, and particularly for those with intermediate or favorable risk genetic groups or cytogenetic risk groups just because we achieve high rates of remission. Our 30-day induction mortality rates are lower now than they were 10 and 20 years ago. Our supportive care is better. And we still have a busy inpatient hospital service here at Mayo Florida and my colleagues in Rochester and Arizona as well giving intensive therapy. So that remains the backbone of curative therapy for younger adults. We are trying to be a little more discriminating about who we administer that to. We are trying to add targeted agents. We know from, now, two different randomized trials that the addition of a FLT3 inhibitor, either midostaurin or more recently quizartinib, has a survival advantage in patients with a FLT3 mutation, or for quizartinib, a FLT3/ITD mutation. And so yes, ‘7+3' remains important.  Off protocol for somebody who just comes in with acute leukemia in a 40-year-old or 30-year-old or even early 60s and fit, we would still be considering ‘7+3' therapy and then waiting for an expedited gene mutation panel and an expedited cytogenetics panel to come back to help us discriminate is that a patient for whom we should be giving a FLT3 inhibitor? I think there's a little more nuance about when we do a day 14 bone marrow, do they really matter as much anymore? I still do them. Some of my colleagues find them less important. But we're still giving intensive therapy. We're still giving high-dose ARA-C consolidation for younger patients who achieve complete remission.  In older adults, it's a different story. You know, it was only in the early part of the 2000s – 2004, 2007 range – where we really got buy-in from randomized studies that low-dose therapy was better than no therapy. There was a lot of nihilism before then about therapy for older adults, especially over age 75. We know that low-dose ARA-C is better than nothing. It looked like azacitidine was better than ARA-C or at least equivalent or slightly better. But with the advent of venetoclax it was a game changer. I ran a national randomized study of intensive therapy in AML. It was the last national randomized study of intensive therapy in older patients right before venetoclax got approved. And we were very excited about our results, and we thought we had some really interesting clinical results. And suddenly that's a little bit obsolete in patients over 70 and particularly over age 75 because of the high remission rates with azacytidine venetoclax or hypomethylating agents, so-called HMAs and venetoclax and the survival advantage. Now, it's not a home run for everybody. We quote 60% to 70% remission rates, but it's a little different based on your cytogenetics and your mutation profile. You have to continue on therapy so it's continuous treatment. It's not with curative intent, although there are some people with long-term remission in it. And the median survival went from 10 months to 15 months. So home run? No, but definitely improved remissions, meaningful for patients off transfusions and better survival. So right now it's hard to find an older adult who you wouldn't give azacitidine and venetoclax or something similar, decitabine, for instance, and venetoclax, unless somebody really was moribund or had very poor performance status or some reason not to. And so ‘7+3' is still relevant in younger adults. We're trying to get better results with ‘7+3' by adding targeted agents and azacitine and venetoclax in older adults.  I think the area of controversy, I guess there are two of them, is what to do in that overlap age between 60 and 75. Should people in that age still get intensive therapy, which we've used for years – the VIALE-A trial of aza-venetoclax was age 75 plus – or with cardiac comorbidities? And I think if you're 68 or 72, many of us are starting to bias towards aza-venetoclax as generally being better tolerated, generally being more outpatient, generally being slow and steady way to get a remission. And it doesn't stop you from going to transplant for somebody who might still be a candidate.  The other area of controversy is somebody under 60 who has adverse cytogenetics where we don't do very well with ‘7+3,' we still give it and we might do just as well with decitabine venetoclax. A lot of us feel that there's equipoise in the 60 to 75 group where we really can ask a question of a randomized study. Retrospective studies might suggest that intensive therapy is a little better, but there are now a couple of randomized studies happening saying, “Can we replace ‘7+3' in that intermediate age with aza-venetoclax?” And for younger adults similarly, we're looking to see how we apply that technology. Those are the areas where we're really trying to investigate what's optimal for patients and that's going to require randomized trials. Dr. John Sweetenham: Oh, that's great, thank you. And I'll just extend that question a little bit more, particularly with respect to the new targeted therapies. How much are they impacting the treatment of these patients in the relapse and refractory setting now? Dr. James Foran: Oh, they're definitely impacting it. When I trained and probably when you trained, AML was still a medical emergency. But that was the thing that you admitted to the hospital immediately, you started therapy immediately. The rule was always that's the one thing that brings the fellow and the consultant in at night to see that new patient on a Friday or Saturday. Now, we'll still admit a patient for monitoring, but we try not to start therapy for the first three or five or seven days if they're stable, until we get those genetics and those genomics back, because it helps us discriminate what therapy to pursue. And certainly, with FLT3 mutations, especially FLT3/ITD mutations, we're adding FLT3 inhibitors and we're seeing a survival advantage. Now, on the surface, that survival advantage is in the range of 7% or 10%. But if you then pursue an allogeneic transplant in first remission, you're taking disease where we used to see 30%, 40% long-term survival, maybe less, and you're pushing that to 60%, 70% in some studies. And so we're now taking a disease that– I don't want to get off topic and talk about Ph+ ALL. But that's a disease where we're actually a little excited. We have a target now, and it used to be something really adverse and now we can do a lot for it and a lot about it.  The other mutations, it's a little more subtle. Now, who knew until 2010 that a mutation in a sugar metabolism gene, in isocitrate dehydrogenase, or IDH was going to be so important, or even that it existed. We know that IDH1 and IDH2 mutations are still a minority of AML, certainly less than 10% to 15%, maybe overall. But we're able to target those with specific IDH1 and IDH2 inhibitors. We get single-agent responses. There are now two approved IDH1 inhibitors on the market. We don't yet have the randomized data that adding those to intensive therapy is better, but we're getting a very strong hint that it might be better in older adults who have an IDH mutation, maybe adding those is helpful and maybe adding those to low-intensity therapy is helpful. Those studies are ongoing, and we're also trying with low-intensity treatments to add these agents and get higher remission rates, deeper remissions, longer remissions. I think a lot of work has to be done to delineate the safety of that and the long-term efficacy. But we're getting hints it's better, so I think it is impacting.  The other area it's impacting is when you pick up adverse mutations and those have crept into our classification systems like an ASXL1 mutation or RUNX1 mutation for instance, or some of the secondary AML mutations like BCOR and others, where that's helping us discriminate intermediate-risk patients who we think aren't going to do as well and really helping us select a group who's more likely to get benefit from allogeneic transplant or for whom at least our cure rates without allo transplant are low. And so I think it's impacting a lot. Dr. John Sweetenham: Great. And I'm going to pick up now, if I may, on a couple of things that you've just mentioned and continue the theme of the relapsed and refractory setting. We've started to see some reports which have looked at the role of immune strategies for patients with AML, in particular CAR T or NK cells. Can you comment a little on this and let us know whether you think either these two strategies or other immune strategies are likely to have a significant role in AML in the future? Dr. James Foran: They are, but I think we're still a step behind finding the right target or the right way to do it. If you think of allogeneic transplantation as the definitive immune therapy, and we know for adverse AML we can improve survival rates and cure rates with an allotransplant, then we know inherently that immune therapy matters. And so how do we do what they've done in large cell lymphoma or in CD19 targeting for B cell malignancies? How do we bring that to acute myeloid leukemia? There have been a number of efforts. There have been at least 50 trials looking at different targets. CD33, CD123, CD7, others, CLL-1. So, there have been a number of different trials looking at how to bind a CAR T or a CAR T construct that can be active. And we have hints of efficacy. There was kind of a provocative paper in the New England Journal of Medicine a year ago in April of last year from a Chinese group that looked at a CD7-based CAR T and it was 10 patients, but they used CD7 positive acute leukemia, AML or ALL and had a CD7-targeted CAR T and they actually incorporated that with a haploidentical transplant and they had really high remission rates. People tolerated it quite well. It was provocative. It hasn't yet been reproduced on a larger scale, but the strong hints that the strategy is going to work.  Now, CD33 is a little tricky to have a CAR T when CD33 is expressed on normal hematopoietic cells. CD123 likewise. That's been something where there's, I think, still promise, but we've struggled to find the trials that make that work. Right now, there's a lot of interest in leveraging NK cells and looking, for a couple of reasons, but NK cells are attractive and NK cell markers might be attractive targets. NK cells might have similar degrees of immune efficacy. It's speculative, but they are likely to have less cytokine release syndrome and less neurotoxicity than you see with CAR T. And so it's kind of attractive to leverage that. We have had some ongoing trials looking at it with bispecifics and there certainly are trials looking at it with CAR NK-based strategies. One of the antigens that people looked at is the NK group 2D. NK group 2D or NKG2D is overexpressed in AML and its ligands overexpressed. And so that's a particular potential target. So, John, it's happening and we're looking for the hints of efficacy that could then drive a pivotal trial to get something approved.  One of the other areas is not restricting yourself just to a single antigen. For instance, there is a compound that's looking at a multi-tumor-associated antigen-specific T-cell therapy, looking at multiple antigens in AML that could be overexpressed. And there were some hints of activity and efficacy and actually a new trial looking at a so-called multi-tumor associated antigen-specific T cell therapy. So without getting into specific conflicts of interest or trials, I do think that's an exciting area and an evolving area, but still an investigational area. I'll stop there and say that we're excited about it. A lot of work's going there, but I'm not quite sure which direction the field's going to pivot to there. I think that's going to take us some time to sort out. Dr. John Sweetenham: Yeah, absolutely. But as you say, exciting area and I guess continue to watch this space for now.  So you've mentioned allogeneic stem cell transplants two or three times during this discussion. Recognizing that we don't have an imatinib for AML, which has kind of pushed transplant a long way further back in the treatment algorithm, can you comment a little on, you know, whether you think the role of stem cell transplantation is changing in AML or whether it remains pretty much as it was maybe 10 years ago? Dr. James Foran: By the way, I love that you use imatinib as an introduction because that was 6 TKIs ago, and it tells you the evolution in CML and you know, now we're looking at myristoyl pocket as a target, and so on. That's a great way to sort of show you the evolution of the field.  Allogeneic transplant, it remains a core treatment for AML, and I think we're getting much smarter and much better about learning how to use it. And I'm just going to introduce the topic of measurable residual disease to tell you about that. So I am a little bit of a believer. Part of my job is I support our allogeneic transplant program, although my focus is acute myeloid leukemia, and I've trained in transplant and done it for years and did a transplant fellowship and all that. I'm much more interested in finding people who don't need a transplant than people who do. So I'm sort of looking for where can we move away from it. But it still has a core role. I'll sidestep and tell you there was an MDS trial that looked at intermediate or high-risk MDS and the role of allogeneic transplant that shows that you about double your survival. It was a BMT CTN trial published several years ago that showed you about double your three-year survival if you can find a donor within three months and get to a transplant within six months. And so it just tells you the value of allotransplant and myeloid malignancy in general. In AML we continue to use it for adverse risk disease – TP53 is its own category, I can talk about that separately – but adverse risk AML otherwise, or for patients who don't achieve a really good remission. And I still teach our fellows that an allotransplant decreases your risk of relapse by about 50%. That's still true, but you have to have a group of patients who are at high enough risk of relapse to merit the non-relapse mortality and the chronic graft versus host disease that comes with it. Now, our outcomes with transplant are better because we're better at preventing graft versus host disease with the newer strategies such as post-transplant cyclophosphamide. There are now new FDA-approved drugs for acute and chronic graft versus host disease, ruxolitinib, belumosudil, axatilimab now. So we have better ways of treating it, but we still want to be discriminating about who should get it.  And it's not just a single-minded one-size-fits-all. We learned from the MORPHO study that was published in the JCO last year that if you have FLIT3-positive AML, FLIT3/IDT-positive AML, where we would have said from retrospective studies that your post-transplant survival is 60% give or take, as opposed to 15% or 20% without it, that we can discriminate who should or shouldn't get a transplant. Now that trial was a little bit nuanced because it did not meet its primary endpoint, but it had an embedded randomization based upon MRD status and they used a very sensitive test of measurable residual disease. They used a commercial assay by Invivoscribe that could look at the presence of a FLT3/ITD in the level of 10 to the minus 5th or 10 to the minus 6th. And if you were MRD-negative and you went through a transplant, you didn't seem to get an advantage versus not. That was of maintenance with gilteritinib, I'll just sort of put that on there. But it's telling us more about who should get a transplant and who shouldn't and who should get maintenance after transplant and who shouldn't.  A really compelling study a year ago from I don't know what to call the British group now, we used to call them the MRC and then the NCRI. I'm not quite sure what to call their studies at the moment. But Dr. Jad Othman did a retrospective study a year ago that looked at patients who had NPM1 mutation, the most common mutation AML, and looked to see if you were MRD positive or MRD negative, what the impact of a transplant was. And if you're MRD negative there was not an advantage of a transplant, whereas if you're MRD positive there was. And when they stratified that by having a FLT3 mutation that cracked. If you had a FLT3 mutation at diagnosis but your NPM1 was negative in remission, it was hard to show an advantage of a transplant. So I think we're getting much more discriminating about who should or should not get a transplant by MRD testing for NPM1 and that includes the patients who have a concomitant FLT3 mutation. And we're really trying to learn more and more. Do we really need to be doing transplants in those who are MRD-negative? If you have adverse risk genetics and you're MRD-negative, I'll really need good data to tell me not to do a transplant, but I suspect bit by bit, we'll get that data. And we're looking to see if that's really the case there, too. So measurable residual disease testing is helping us discriminate, but there is still a core role of allogeneic transplant. And to reassure you, compared to, I think your allotransplant days were some time ago if I'm right. Dr. John Sweetenham: Yes. Dr. James Foran: Yeah. Well, compared to when you were doing transplants, they're better now and better for patients now. And we get people through graft versus host disease better, and we prevent it better. Dr. John Sweetenham: That's a great answer, James. Thanks for that. It really does help to put it in context, and I think it also leads us on very nicely into what's going to be my final question for you today and perhaps the trickiest, in a way. I think that everything you've told us today really emphasizes the fact that the complexity of AML treatment has increased, primarily because of an improved understanding of the molecular landscape of the disease. And it's a complicated area now. So do you have any thoughts on what type of clinical environment patients with AML should be evaluated and treated in in 2025? Dr. James Foran: Yeah, I want to give you a kind of a cautious answer to that because, you know, I'm a leukemia doctor. I work at a leukemia center and it's what we focus on. And we really pride ourselves on our outcomes and our diagnostics and our clinical trials and so on. I am very aware that the very best oncologists in America work in private practice and work in community practice or in networks, not necessarily at an academic site. And I also know they have a much harder job than I have. They have to know lung cancer, which is molecularly as complicated now as leukemia, and they have to know about breast cancer and things that I don't even know how to spell anymore. So it's not a question of competence or knowledge. It's a question of infrastructure. I'll also put a little caveat saying that I have been taught by Rich Stone at Dana-Farber, where I did a fellowship a long time ago, and believe Rich is right, that I see different patients than the community oncologists see with AML, they're seeing different people. But with that caveat, I think the first thing is you really want to make sure you've got access to excellence, specialized hematopathology, that you can get expedited cytogenetics and NGS testing results back. There was a new drug, approved just a few months ago, actually, for relapsed AML with a KMT2A rearrangement, revumenib. We didn't talk about the menin inhibitors. I'll mention them in just a second. That's a huge area of expansion and growth for us. But they're not found on NGS platforms. And normal cytogenetics might miss a KMT2A-rearrangement. And we're actually going back to FISH panels, believe it or not, on AML, to try to identify who has a KMT2A-rearrangement. And so you really want to make sure you can access the diagnostic platforms for that.  I think the National Referral Labs do an excellent job. Not always a really fast job, but an excellent job. At my institution, I get NGS results back within three days or four days. We just have an expedited platform. Not everybody has that. So that's the key, is you have to be able to make the diagnosis, trust the pathologist, get expedited results. And then it's the question of trying to access the targeted medications because a lot of them are not carried in hospital on formulary or take time to go through an insurance approval process. So that's its own little headache, getting venetoclax, getting gilteritinib, getting an IDH1 inhibitor in first line, if that's what you're going for. And so I think that requires some infrastructure. We have case managers and nurses who really expedite that and help us with it, but that's a lot of work. The other piece of the puzzle is that we're still with AML in the first month and maybe even the second month. We make everybody worse before we make them better. And you have to have really good blood bank support. I can give an outpatient platelet transfusion or red cell transfusion seven days a week. We're just built for that. That's harder to do if you're in a community hospital and you have to be collaborating with a local blood bank. And that's not always dead easy for somebody in practice. So with those caveats, I do find that my colleagues in community practice do a really good job making the diagnosis, starting people on therapy, asking for help. I think the real thing is to be able to have a regional leukemia center that you can collaborate with, connect with, text, call to make sure that you're finding the right patients who need the next level of diagnostics, clinical trial, transplant consults, to really get the best results.  There was some data at ASH a couple of years ago that looked at – the American Society of Hematology and ASCOs had similar reports – that looked at how do we do in academic centers versus community practice for keeping people on therapy. And on average, people were more likely to get six cycles of therapy instead of three cycles of therapy with azacitidine venetoclax at an academic center. Now, maybe it's different patients and maybe they had different cytogenetics and so on, but I think you have to be patient, I think you have to collaborate. But you can treat those patients in the community as long as you've got the infrastructure in place. And we've learned with virtual medicine, with Zoom and other platforms that we can deliver virtual care more effectively with the pandemic and beyond. So I think we're trying to offer virtual consults or virtual support for patients so they can stay in their home, stay in their community, stay with their oncologists, but still get access to excellent diagnostics and supportive care and transplant consults, and so on. I hope that's a reasonable answer to that question. It's a bit of a nuanced answer, which is, I think there's an important role of a leukemia center, and I think there's a really fundamental role of keeping somebody in the community they live in, and how we collaborate is the key to that. And we've spent a lot of time and effort working with the oncologists in our community to try to accomplish that.  John, I want to say two other things. I didn't mention in the molecular platforms that NPM1 mutations, we can now target those on clinical trials with menin inhibitors. We know that NPM1 signals through the Hoxa9/Meis1 pathway. We know that similar pathways are important in KMT2A rearrangements. We know that there are some other rare leukemias like those with NUP98 rearrangement. We can target those with menin inhibitors. The first menin inhibitor, revuminib, was approved by the FDA for KMT2A. We have others going to the FDA later this year for NPM1. There are now pivotal trials and advanced expanded phase 1/2 studies that are showing 30% response rates. And we're looking to see can we add those into the first-line therapy. So, we're finding more targets.  I'll say one last thing about molecular medicine. I know I'm a little off topic here, but I always told patients that getting AML was kind of like being struck by lightning. It's not something you did. Now, obviously, there are risk factors for AML, smoking or obesity or certain farm environments, or radioactive exposures and so on. But bit by bit, we're starting to learn about who's predisposed to AML genetically. We've identified really just in the last five or eight years that DDX41 mutations can be germline half the time. And you always think germline mutations are going to cause AML in a younger patient, but the median age is 60 to 70 just like other AMLs. They actually might do pretty well once they get AML. We've reported that in several papers. And so we're trying to understand who that has a RUNX1 mutation needs germline testing, who with a DDX41 needs germline testing. And we're trying to actually come up with a cleaner pathway for germline testing in patients to really understand predisposition, to help with donor selection, to help with family counseling. So I think those are other areas where a leukemia center can contribute for somebody in who's community practice to understand genomic or genetic complexity in these patients. And we're starting to develop the databases that support that. Dr. John Sweetenham: Yeah, great. Thanks, James. I loved your answer about the clinical environment too. And I know from a patient-centric perspective that I know that patients would certainly appreciate the fact that we're in a situation now where the folks taking care of them will make every effort to keep them close to home if they possibly can.  I want to thank you, James, for an incredible review of a very complex subject and I think you did a great job. I think we all will have learned a lot. And thanks again for being willing to share your insights with us today on the ASCO Daily News Podcast. Dr. James Foran: John, it's my pleasure.

The discussion covers a range of topics, including 2nd line options for advanced HCC after progression on 1st line TKIs and IO-based therapies, as well as: How to approach sequencing in clinical practice The available data supporting sequencing strategies When to switch to 2nd line therapy and what to consider when doing so This is the second video podcast episode in a 4-part series. Access the rest of the series here: Part 1 - The use of IO in unresectable HCC Part 3 - Intermediate HCC: treatment options and strategies (coming soon) Part 4 - The evolving role of IO in intermediate HCC (coming soon)   Clinical takeaways Prospective Phase 3 data on 2nd line options in advanced HCC, particularly after immunotherapy, is limited, highlighting the need for further evidence to guide optimal treatment decisions When switching to 2nd line therapy, it is essential to evaluate all the available treatment options to ensure the optimal choice for each patient, considering efficacy, tolerability, liver function, and quality of life. Switching to 2nd line therapy should be considered in cases of clear disease progression, such as the appearance of new lesions outside the liver. Best supportive care should also be considered Managing side effects of 2nd line treatments (e.g. hypertension, skin toxicity, proteinuria) is critical for maintaining quality of life and providing optimal disease management Effective management requires a multidisciplinary team effort, including oncologists, hepatologists, interventional radiologists, and other specialists to optimise outcomes and proactively manage symptoms like hepatic decompensation.   Don't forget to like, subscribe, and check out more episodes for in-depth discussions on oncology topics!   Website: http://www.oncbrothers.com/   X/Twitter: https://twitter.com/oncbrothers   Contact us at info@oncbrothers.com

In this episode of JCO Article Insights, Rohit Singh interviews Dr. Ticiana Leal on the editorial, "Back to the Drawing Board: Overcoming Resistance to PD-1 Blockade." TRANSCRIPT The guests' disclosures can be found in the transcript. Dr. Rohit Singh: Hello and welcome to JCO's Article Insights. I am your host Rohit Singh and today we will be discussing the JCO article, “Back to the Drawing Board: Overcoming Resistance to PD-1 Blockade.” And we are joined by the senior author of the article, Dr. Ticiana Leal. Dr. Leal is an Associate Professor in the Department of Hematology and Medical Oncology at Emory University School of Medicine, and she serves as director of Thoracic Medical Thoracic Oncology Medical Program and Multidisciplinary Thoracic Oncology Leader at the Winship Cancer Institute. She also served as a member of the Board of Directors at the Georgia Society of Clinical Oncology.  Dr. Leal, welcome to our podcast and thank you for joining us. Dr. Ticiana Leal: Thank you, Rohit. Thank you for this interesting opportunity to discuss our editorial. My co-authors and I are very glad to be here today. So, Dr. Jennifer Carlisle and Dr. Liu were co-authors with me on this editorial. Dr. Rohit Singh: It's a really good article. And just for our audiences, the article again, titled “Back to the Drawing Board: Overcoming Resistance to PD-1 Blockade,” it discusses the challenges and the potential strategies for overcoming resistance to immune checkbox inhibitors in patients with non-small cell lung cancer. In this article, Dr. Leal and colleagues talk about the second line of drug when the patient developed disease progression while immunotherapy and they develop resistance and their definitions and what to do.  So, to Dr. Leal, can you please explain the mechanisms of primary and acquired resistance to immune check prohibitors in non-small cell lung cancer? I also saw in your article you proposed the definition of immunotherapy resistance in solid tumors, distinguishing between primary resistance and acquired resistance. So, if you can please share your thoughts and explain their mechanism. Dr. Ticiana Leal: So primary resistance and acquired resistance are related to tumor intrinsic and tumor extrinsic factors. And this is mainly clinically defined as of now according to previous response patterns and timing of occurrence, and these definitions can be heterogeneous, and we certainly think that biologically they can be very different. And it can be different according to prior therapy, whether patients got immunotherapy as PD-1, PD-L1 inhibitor alone or combination strategy with CTLA-4, or the combination with chemotherapy. But the patterns of resistance can be very different and can be based on defects and antigen presentation. It can also be due to tumor microenvironment immunosuppressive effects, and there are also additional inhibitory checkpoints that can be involved.  The definition in terms of when to call it primary or acquired resistance at this point has really been based on consensus guidelines by SITC, by Esmo, as well as our group Lung-MAP has developed clinical trials in this space. Specifically, through Lung-MAP, we've defined and incorporated the definition of acquired resistance as patients who have had prior exposure of 84 days or greater and then have had progression of their disease.  Dr. Rohit Singh: I can see why it is so challenging to come up with a standard definition for immune checkpoint resistance and I think incorporating these definitions and predictive biomarkers for clinical trial design is going to be more important going forward. Your article talks about CONTACT-01 study, so can you please discuss the CONTACT-01 study and how the shifting treatment paradigm in the first-time study impacted it and at the same time also discuss the potential implication of the differential outcome observed between the men and women in the CONTACT-01 study. Dr. Ticiana Leal: CONTACT-01 was a much-awaited study. The authors, Dr. Neal et al, looked at a very important question in the area of immunotherapy resistance. So, CONTACT-01 was a randomized phase three global study that investigated the combination of cabozantinib plus atezolizumab versus docetaxel in patients previously treated with chemotherapy and immunotherapy. And as background, cabozantinib is an inhibitor of multiple receptor tyrosine kinases including VEGFR-2, MET, RET and TAM family kinases. Preclinically, cabozantinib could lead to immuno permissive tumor microenvironment and so it was rational to combine it with a PD-1 inhibitor. In early results of a phase 1B expanded cohort of COSMIC-021 showed really promising results of this combination which led to the rationale of CONTACT-01. In this study, however, patients that were included had different prior treatment sequences. They could have had prior immunotherapy alone followed by chemo or the opposite, or they could have had prior immunotherapy and then upon progression gotten a combination of immunotherapy plus chemotherapy. That to say that immunotherapy rechallenge is something that people are doing in clinical practice given the unmet need and the desire to overcome immunotherapy resistance. But perhaps that also includes a more resistant population of patients, and these patients certainly could have had heterogeneous mechanisms of resistance which could have impacted these results.   The study did not meet the primary endpoint of overall survival. We saw a median overall survival of 10.7 months with the combination of atezo plus cabo and 10.5 months with docetaxel alone. In terms of the differences between sex that we saw in the CONTACT-01 study, just to go back in terms of the preclinical studies that have been done, there have been some preclinical studies that demonstrated that perhaps there may be some biological differences in models of different genders in mice. However, in the clinical setting, there have been, I think, contradicting results. A meta-analysis showed that perhaps women derive less benefit than men. Other studies have shown that perhaps women have more adverse events to immunotherapy. In this study specifically, only about 20% of the patients enrolled were women and the majority actually had non squamous histology. And we saw here less benefit for immunotherapy in women. But again, I think the numbers here are quite small. This is an exploratory analysis and I do think it highlights though the importance of making sure that we include populations and have higher rates of accrual, not only in women, but in other representative populations. In this study, only about 1% of the patients were black. Dr. Rohit Singh: Yeah. Thank you so much for highlighting those disparities. I think it's very important to make sure that we have proper representation of all the groups in our trials. I think based on just coming off the VEGF inhibitors, I think the Lung-MAP trial S1800A, showed a significant improvement in median OS with the combination of pembrolizumab and ramucirumab compared to standard of care. Do you envision any future commission therapies targeting the VEGF pathway with immune prohibitors in non-small cell lung cancer?  Dr. Ticiana Leal: I definitely think that targeting VEGF with multikinase TKIs based on the studies that we have seen, several now randomized phase 3 studies showing that this strategy is ineffective. So, this has been quite disappointing. But we've now seen the results of CONTACT-01, that we're just discussing here, but also other studies, including SAPPHIRE, which was also a randomized phase 3 that investigated nivolumab plus another VEGF multikinase TKI, sitravatinib. And then we also saw LEAP-008, which was a negative study investigating lenvatinib plus pembrolizumab. There still is a question though, whether you can target the VEGF pathway inhibition with a monoclonal antibody, so that's ramucirumab targeting VEGFR-2 plus ICI, and whether that can actually be an effective strategy. In our Lung-MAP trial, the S1800A, this study was a randomized phase 2. Here we used the definition of acquired resistance of patients receiving prior immune checkpoint inhibitor for a minimum of 84 days, and they were randomized to the combination of pembrolizumab plus ramucirumab versus investigator's choice of standard of care, which did include docetaxel, ramucirumab, docetaxel gemcitabine and methotrexate. This was a positive study. It led to significant improvement in median overall survival and there weren't any significant safety signals here. And we're waiting for another confirmatory study called the Pragmatica-Lung study.  Dr. Rohit Singh: Yeah, I did have one patient who raced through pembro, and I utilized this combination and was able to get some responses.  You mentioned Pragmatica-Lung trial. Can you provide more information about the ongoing Pragmatica-Lung trial and its potential impact on the treatment paradigm? Dr. Ticiana Leal: Yeah, the Pragmatica-Lung trial is an ongoing study, S2302. This is an effort that is ongoing. Dr. Karen Reckamp is the chair of this study. And this is a study that actually has a very, I think, modern study design. The term Pragmatica, this is an effort that is supported by the NCI to really propose a clinical trial design that is pragmatic to promote diversity and inclusion in clinical trials. The aim of this trial specifically is to validate what we saw in terms of overall survival in S1800A. So, in this study, patients with previously treated advanced non-small cell lung cancer are randomized 1:1 to the combination of pembrolizumab plus ramucirumab versus standard of care for patients previously treated with immunotherapy and chemotherapy for stage 4 recurrent non-small cell lung cancer. Primary endpoint here is overall survival. And I think this kind of highlights what we were talking about in terms of empowering investigators to treat patients in a clinical trial more so like a real-world setting. And I think this can be paradigm changing and decrease barriers to enrollment and also include now the real-world population that we see in clinical practice. Dr. Rohit Singh: Yeah, changing gears a little bit. I think your article also mentioned other agents that have been tested in ICI resistance settings, like lenvatinib-sitra. However, those trials results have been disappointing. What are the possible reasons behind those dose point results with multikinase inhibitors?  Dr. Ticiana Leal: We saw some really interesting, promising overall survival results with these combinations in phase two setting. In the phase 1B expansion with CONTACT-01, we saw prolonged overall survival that we thought would be promising enough to investigate in a phase 3. Ultimately, I don't know because there weren't any biomarkers that we could really tease out what was going on. Again, to highlight that both in LEAP-008 as well as CONTACT-01, there was no definition of immunotherapy resistance, which could have impacted, and we did choose the definition for SAPPHIRE, that patients had to have acquired resistance and immunotherapy had to be the most recent prior therapy. Ultimately, one potential reason for why these are not effective could be that this targeting with a multikinase TKI with multiple targets is ineffective, and you really have to target VEGF more precisely, which is the case here of ramucirumab, which targets VEGFR-2, and whether there are differences between a TKI and a monoclonal antibody may also impact the outcomes here.  Dr. Rohit Singh: You mentioned biomarkers. Do you think, are there any other potential biomarkers beyond PDL-1 or human mutation burden expression that can help us predict the response image checkpoint, especially in non-small cell lung cancer? Dr. Ticiana Leal: I think that's a great question. I definitely think that more effort needs to be dedicated, and of course, there are multiple efforts in this direction. One of the challenges, obviously, has been to obtain tissue to do this biomarker testing in clinical trials. When you look at CONTACT-01, they did PDL-1 expression, but this was all based on archival tissue and it was all based on standard of care, local testing. So, a lot of heterogeneity there, and certainly using PDL-1 at baseline from initial diagnosis for a second line trial may have significant flaws there. Ultimately, right now, for clinical practice, there isn't anything that's ready for prime time. But certainly, it sounds like, based on what we're seeing, that combining biomarkers is more likely to improve the accuracy. And I think a single biomarker alone is probably going to have insufficient predictive capacity. It'd be great to be able to better comprehensively characterize an individual's tumor, to individualize immunotherapy strategies in this relapse setting.  Dr. Rohit Singh: Yeah, definitely. We need more, better biomarkers. Coming to your point of heterogeneity, PD-L1. I myself had a patient, when we got PDL expressions from one site, they gave us one to 49%. However, for the testing, I sent the patient to a further lab at outset and PDL turned out to be 80%. But that was from a different site because of the bio sets only. Yeah, to your point, it's very heterogeneous and definitely we need to be more cautious interpreting those.  In that trial, in CONTACT-01, we have, through the patient who have oncogenetic lung cancer. Are there any plans to explore the role of immune checkpoint in oncogenetic lung cancer, especially like non-EGFR, non ALK? I know those are the ones that we have seen in multiple studies that don't respond but are other oncogenetic lung cancer is getting more and more target treatments coming out for non-small lung cancer? Dr. Ticiana Leal: Yeah. So, for patients with driver mutations, the paradigm has been well established that if there is a driver mutation, the patient should receive the appropriate targeted therapy. Immunotherapy as monotherapy has been ineffective in a lot of the patients with driver mutations beyond EGFR and ALK, certainly RET and HER2, ROS1, or other driver mutations that we believe that immunotherapy alone is ineffective. However, we are seeing some interesting ongoing clinical trials, or completed clinical trials investigating immunotherapy in patients with driver mutations. Going back to the EGFR population, we recently saw the results of HARMONi-A, which investigated ivonescimab, which is a bispecific antibody hitting PD-1, and VEGF, that in combination with chemotherapy, improved progression free survival in patients with EGFR mutated, non-squamous, non-small cell lung cancer with progression on prior TKI treatment. So, I think it is still an area of active investigation, and I do think that ongoing trials, perhaps with different PD-1, PD-L1 combination strategies such as bispecifics may be interesting but does require investigation. Dr. Rohit Singh: Yeah, definitely. It looks like combination therapy is going to be the most likely answer coming forward with more research, we're able to figure out the best possible treatment in this subgroup of patients. Considering the current challenges and ongoing research efforts, how do you see the field of non-small cell treatment evolving in coming years? Dr. Ticiana Leal: This is an interesting and important question. I think it's been really exciting to be working in thoracic oncology research. We have seen that these research efforts have led to advancement in the field. I think we need to continue to partner and collaborate with institutions, partner with industry, and also with patients and patient advocates to design clinical trials that are really going to focus on the needs of our patients in clinical trials. The gap in the second line and beyond after immunotherapy failure is a significant one. So, I do think that the challenges are to continue to develop biomarkers, to really understand who will benefit from immunotherapy strategies, who benefits from combinations, and most importantly, who does nothing. I think biomarkers are going to be something that we need to continue to incorporate in clinical trials, and I do think that there's a lot of room for hope and promise in the field. We've seen some interesting results with antibody drug conjugates and the combinations there may also be of interest. And then other important strategies, we're looking at T Cell engagers and different drugs with different mechanism of actions, including CAR T and vaccines. So beyond immune checkpoint inhibitors, I think we have different classes of drugs that may lead to different treatment strategies for patients in second line and beyond.  Dr. Rohit Singh: Yeah, certainly we have seen such extensive development in lung cancer. However, there's still a lot to be done as you just mentioned.  Thank you so much Dr. Leal for your time and great insights discussing your article with us. Dr. Ticiana Leal: Thank you.

At the 2024 Kidney Cancer Research Summit (KCRS), CancerNetwork® spoke with various experts in the kidney cancer field about potential advancements in disease detection and updated efficacy data on immunotherapy and other treatment strategies in patients with renal cell carcinoma (RCC). Karl Semaan, MD, MSc, a postdoctoral oncology research fellow at Dana-Farber Cancer Institute, discussed the implications of findings related to the use of an investigational tissue-informed liquid biopsy epigenomic profiling tool for detecting sarcomatoid differentiation in RCC.1 According to Semaan, this method may avoid the sampling errors and spatial heterogeneity challenges associated with traditional biopsy strategies. Additionally, Neil J. Shah, MBBS, an assistant attending physician from Memorial Sloan Kettering Cancer Center, spoke about data from a real-world study evaluating treatment patterns and outcomes in those with metastatic RCC following prior receipt of immunotherapy and tyrosine kinase inhibitors (TKIs).2 Data showed no differences in overall survival (OS) outcomes across different immunotherapy- and TKI-containing regimens. Based on these findings, Shah emphasized a need for additional novel therapeutic approaches to help improve outcomes in later-line settings of treatment. Bradley A. McGregor, MD, director of Clinical Research for the Lank Center of Genitourinary Oncology and medical oncologist specializing in genitourinary malignancies at Dana-Farber Cancer Institute, highlighted findings from his presentation on a phase 1b study (NCT04627064) evaluating treatment with abemaciclib (Verzenio) in a pretreated metastatic clear cell RCC population.3 Among 11 patients who received abemaciclib, 1 had stable disease, 8 had progressive disease, and 2 were not evaluable for response. Additionally, the median progression-free survival (PFS) and overall survival (OS), respectively, was 1.8 months (95% CI, 1.5-1.9) and 9.1 months (95% CI, 2.1-15.3). Although abemaciclib monotherapy yielded no responses in the study, McGregor highlighted the potential clinical utility of administering the agent in combination with other therapies. Findings from his presentation suggested that CDK4/6 inhibitors may demonstrate a synergistic effect when combined with HIF-2α inhibitors, which is a potential strategy that investigators are evaluating with belzutifan (Welireg) and palbociclib (Ibrance) combination therapy as part of the phase 1/2 LITESPARK-024 trial (NCT05468697).

On today's episode, we'll be discussing practice-changing abstracts and other key advances in hematological malignancies that were featured at the 2024 ASCO Annual Meeting. Joining me for this discussion is an old friend, Dr. Marc Braunstein, a hematologist and oncologist from the NYU Langone Perlmutter Cancer Center.  Our full disclosures are available in the transcript of this episode. Marc, it's great to have you back on the podcast again. There were some important studies in the heme space at the Annual Meeting this year, and we're very pleased that you're able to share your takeaways.  Dr. Marc Braunstein: Thank you, John. It's great to be back again. Dr. John Sweetenham: Let's start out, Marc, with LBA6500. This abstract reports the primary results of the ASC4FIRST trial, and this was a trial comparing asciminib with investigator selected tyrosine kinase inhibitors in newly diagnosed patients with chronic myeloid leukemia. Could you tell us a little about the trial and how you think it's going to impact clinical practice? Dr. Marc Braunstein: Absolutely. So, asciminib is an oral tyrosine kinase of the ABL kinase domain. As we know in CML, the BCR-ABL translocation is characteristic of the disease, and asciminib is approved for chronic phase CML with a T315I resistance mutation or for patients who have received 2 or more prior lines of therapy. So the ASC4FIRST trial was a randomized trial of 405 patients with newly diagnosed chronic phase CML who are randomized one to one to receive either asciminib at 80 milligrams once daily, or investigator's choice of a first generation TKI imatinib or one of three second generation TKIs nilotinib, dasatinib, or bosutinib. The primary endpoint of the study was the major molecular response, or MMR, at 48 weeks. Pretty much, the study met its primary endpoint with a 67% rate of MMR at 48 weeks, with asciminib versus 49% in patients treated with the investigator's choice of TKI. And in addition, the major molecular remission or MMR of 4.5, which is a deep remission, those rates were higher as well, with asciminib versus investigator's choice at a rate of 39% versus 21% when comparing the groups. Furthermore, when we looked at toxicity, there were fewer grade 3 or higher adverse events, with the asciminib at 38% versus either 44% with the first generation, or 55% with the second generation TKI, and fewer discontinuations as well with asciminib.  So I think this abstract is practice-changing. I think it offers compelling data to use asciminib upfront for chronic phase CML. Those who don't agree with that sentiment might argue that we want to see longer term follow up. There's a planned follow-up at 96 weeks. We would want to see the rate of progression to acute myeloid leukemia and of course overall survival as well. But I think the abstract certainly shows an improvement in outcomes with asciminib versus our current array of TKIs. Dr. John Sweetenham: Yeah, I think it certainly is, at least at minimum, potentially practice changing. I agree with you. Just one question, and this may be a little bit speculative, but do you have any thoughts about treatment free survival with asciminib and how that might line up against some of the other TKIs? Dr. Marc Braunstein: Yeah, that's a great question. The abstract did not necessarily address that, patients were treated until progression, but we know that with the current landscape of TKIs, that in patients who have achieved a deep MR of 4 or 4.5 for at least 2 years who discontinue their TKI, the rate of relapse is about 50%. The current study, the ASC4FIRST, doesn't address that, but I think it's a really good question about whether, for those patients who have achieved a deep remission, whether they can eventually stop asciminib down the line. Dr. John Sweetenham: Yeah, I guess it's one of those ‘watch this space' things.  So we'll see how the data mature out. And let's move on to what I think is another potentially practice-changing study, at least in certain parts of the world. And that's [the] LBA7000 study in classical Hodgkin lymphoma. As you remember, this was a German Hodgkin lymphoma study group trial which looked at the tolerability and efficacy of a novel regimen, BrECADD versus eBEACOPP for patients with advanced stage classical Hodgkin lymphoma in their study, which is known as GHSG HD21. Can you give us your thoughts and take home messages from this trial? Dr. Marc Braunstein: Yeah, John, absolutely. So the German HD21 study is a phase 3 study of 1,500 patients with classical Hodgkin lymphoma. The majority were stage 3 or 4, 84%, that compared two regimens BEACOPP to BrECADD. The major difference between these 2 groups being that the newer BrECADD regimen swaps out bleomycin for brentuximab vedotin, which is an anti-CD30 antibody drug conjugate. Also, in the BrECADD regimen they eliminate vincristine that's incorporated into BEACOPP. Those are kind of the global differences between these 2 regimens. And when comparing these, they looked at the primary endpoint of progression-free survival. Of note, in this study there was a PET adjusted approach where if patients achieved interim PET negativity after 2 cycles, that was followed by an additional 2 cycles of their treatment as opposed to 4 cycles if they were PET positive after the initial 2 cycles of their respective treatment. And of note, there were similar rates of PET2 negativity between both arms, about 58% in both arms.  So at a median follow-up of 48 months, the 4-year progression-free survival was significantly better with the brentuximab containing BrECADD regimen at 94% versus 91% with a hazard ratio of 0.66. And the overall survival of the BrECADD arm was 98.6%, which is very high and impressive. The 4-year overall survival was similar between the arms at around 98%, but of note, there were fewer severe adverse events with BrECADD, the brentuximab containing arm versus BEACOPP at about 42% versus 59% and interestingly less peripheral neuropathy with the brentuximab containing BrECADD. So we're doing extremely well in treating advanced stage classical Hodgkin lymphoma. So the bar is set very high. But in this study, the rates of progression-free survival and overall survival are very impressive.  While these intensive regimens tend to be used outside of the U.S., there are several notable benefits of the study, including greater than 50% PET2 negativity and high rates of progression-free survival at 4 years. In discussing this abstract, it's worth noting that there are other competing regimens, if you want to call it that, that are more commonly used in the U.S. So the ECHELON-1 study looked at brentuximab AVD compared with ABVD with bleomycin and it was a 94% versus 89% 6-year overall survival rate favoring the brentuximab containing A+AVD regimen. And lastly, more recently, the SWOG S1826 study that hasn't been published but was presented in abstract form looked at nivolumab AVD versus brentuximab AVD at a median follow up of 12 months showed a progression-free survival of 94% versus 86%. And that study still has yet to be published and needs to mature. But both of those regimens are in the NCCN guidelines. So, we're definitely pushing the bar higher in terms of improving responses in treating advanced classical Hodgkin lymphoma. Dr. John Sweetenham: I think that there's no question that these results from BrECADD are very impressive. But I'm taken back to what I think has been a kind of philosophic discussion in Hodgkin lymphoma now for a number of years about balancing disease control and efficacy against the potential short-term and long-term toxicity of the regimens, particularly when you have very effective salvage therapies for those patients who may suffer a relapse. So I think that this is a discussion over whether you take a very intensive, upfront approach to Hodgkin lymphoma versus something that may be less and slightly less intensive. I suspect that's a discussion that's going to continue for a long time. I don't know what you feel, but my own feeling about this is that this study will likely have a major influence over treatment of Hodgkin lymphoma, particularly in western Europe. Less likely in the US.., I would think. I don't know what your thoughts about that are. Dr. Marc Braunstein: Well, it's a great question. In SWOG S1826, that study did include pediatric patients. In HD21, the median age was 31 and did not include pediatric patients. So I think we have to be selective in terms of fitness and which patients may be better suited for different regimens. But I think what all these studies show is certainly when we incorporate novel immunotherapies, whether it's brentuximab vedotin, nivolumab, we improve progression-free survival and even overall survival. Dr. John Sweetenham: Absolutely.  So let's shift gears now and take a look at Abstract 7500, the IMROZ study. This was the study of isatuximab, bortezomib, lenalidomide and dexamethasone versus VRD alone for transplant ineligible patients with newly diagnosed multiple myeloma. I know we discussed this in our preview podcast a few weeks back, Marc, but I just wonder now, having seen the data in more detail, what do you think of the important takeaways? And again, are we looking at a new standard of care? Dr. Marc Braunstein: You know, there are many standards of care in multiple myeloma, but we're always looking to make improvements on the regimens we have at our disposal. So, just to recap, IMROZ is a phase 3 randomized study of the anti-CD38 monoclonal antibody isatuximab with the backbone of bortezomib, lenalidomide, dexamethasone or VRD versus VRD alone, specifically, in transplant ineligible newly diagnosed multiple myeloma patients age less than 80. They studied 446 patients in this study, randomized 3 to 2 to Isa-VRD versus VRD alone, with the primary endpoint of progression free survival. Now, similar to other studies where they included a monoclonal antibody up front, the study met its primary endpoint of improving progression-free survival with the quad regimen containing the monoclonal antibody isatuximab versus VRD alone.  So what was interesting about the study, it's really the first of its kind to be presented that specifically looked at transplant ineligible patients, which is presumably a less fit or perhaps more frail population that wouldn't go on to consolidation with stem cell transplant. And in this study, the progression-free survival at 5 years was 63% versus 45%, clearly superior when you included isatuximab. And the rates of complete remission and MRD negativity were all significantly improved, too. However, that was also met with slightly more grade 3 or higher treatment emergent adverse events, 92% versus 84% in the control arm. There are also 11% grade 5 treatment emergent adverse events with the isatuximab group versus 5.5% with VRD alone. Although there was no major difference in treatment discontinuation. One small caveat worth noting, too, is that high-risk patients in this study, when presented at ASCO, did not necessarily show a difference in benefit, although there wasn't necessarily a detriment either.  So, John, I think that clearly quadruplet regimens are superior in outcomes of efficacy to triplets, even in transplant-ineligible patients. But I think we have to tailor these treatments to individual patients because I think when it comes to transplant-ineligible patients, it's a spectrum of patients who may be more or less fit for quad regimens versus triplet regimens. It's also worth noting, though, that in this study, the patients are really only getting a quad regimen for 4 cycles. They get their Isa-VRD, and then you drop the bortezomib.  So when we think about quads, it's not that they're getting the quad regimen indefinitely, it's really for the induction cycles. But still, I think we have to be aware of potential safety issues. Dr. John Sweetenham: Okay, great. And let's stay on the theme of multiple myeloma, Marc, and talk a little bit about Abstract 7504, which was a subgroup analysis of the CARTITUDE-4 study. This is a report on the use of ciltacabtagene autoleucel versus standard of care in patients with functional high risk multiple myeloma. Can you give us your thoughts on this and maybe put it into a bit of context for us?  Dr. Marc Braunstein: Absolutely, John. It's really a great time to be in the field of multiple myeloma. We're making tremendous progress, but when we think about one of the unmet needs, it's just consistently the high-risk patients who have shorter responses and are at higher risk for poorer outcomes. Just to review, cilta-cel is one of the 2 available anti-BCMA CAR T-cell products available for the treatment of relapsed or refractory multiple myeloma. Very recently, the FDA approved cilta-cel for lenalidomide refractory patients after 2 or more prior lines of therapy based on the CARTITUDE-4 study, which was published by San-Miguel and colleagues in New England Journal of Medicine in July 2023. And that study randomized 419 patients with multiple myeloma with 1 to 3 prior lines of therapy to receive either cilta-cel or physician's choice of standard of care, which was either 1 of 2 triplet regimens, a pomalidomide, bortezomib, dexamethasone or daratumumab, pomalidomide and dexamethasone. It's worth noting that about 25% of the patients in the CARTITUDE-4 study had prior anti-CD38 antibody treatment previously and the carfilzomib was not included in one of the standard-of-care arms, and we know that those regimens containing carfilzomib do increase survival in relapsed myeloma.  Nevertheless, the primary outcome of progression-free survival was not reached in the CAR T-cell arm versus 11.8 months in the standard-of-care arm, with a significant reduction in progression of 74%. So clearly a positive study and CAR T-cell therapy is included in the NCCN guidelines for patients who have an early relapse from their myeloma. The current abstract by Costa et al focused specifically on a subgroup of 79 patients from CARTITUDE-4 in second line of treatment and looked at what they called functional high-risk myeloma, defined as progression of disease within 18 months of initial treatment or after stem cell transplant. Again, the study showed a retained benefit of cilta-cel with significant improvement in progression-free survival either not reached or 12 months with the control standard of care arm, as well as complete remission rate and rates of MRD negativity of 65% versus 10% in the control.  The overall survival outcome was still immature and not presented. Nevertheless, cilta-cel is clearly superior to standard-of-care triplet regimens. I think that for patients with high risk, they clearly derive a benefit from CAR T-cell therapy if they have short progression-free survival after initial therapy.  Dr. John Sweetenham: Thanks, Marc. So let's round this out by talking about another area of unmet need, I guess in a way in a difficult to treat patient group. And that's Abstract 7007, the SYMPATICO study. This is a study which looks at the efficacy and safety of ibrutinib and venetoclax in patients with mantle cell lymphoma who had a mutated TP53. Can you just briefly review this for us and tell us what you think we should be taking away from this studys? Dr. Marc Braunstein: So, mantle cell lymphoma typically has an aggressive behavior, but the subgroup of patients with a P53 mutation tend to have the poorest outcomes and do represent an area of unmet need. Although BTK inhibitors are making important improvements in mantle cell lymphoma, they have yet to be approved in newly diagnosed mantle cell lymphoma. Acalibutinib and zanubrutinib are FDA-approved BTK inhibitors for previously treated mantle cell lymphoma. Ibrutinib was withdrawn from the market in the U.S. for mantle cell lymphoma. Dr. Michael Wang's group presented late-breaking data from the phase 3 SYMPATICO trial at ASH 2023, in which 267 patients with relapsed refractory mantle cell lymphoma were randomized to receive either ibrutinib plus the BCL2 inhibitor venetoclax or ibrutinib plus placebo after 1 to 5 prior lines of therapy. And that study showed a 32 versus 22 months progression-free survival at a median follow up of 51 months. The current abstract, also by Dr. Wang and colleagues, looked at the subgroup of patients who had a P53 mutation and included an open label cohort of 44 patients in the first line of treatment and a relapse refractory cohort of 75 patients, and compared this subgroup of patients with P53 mutation to those without. When we look at the outcomes, the patients who did not have a P53 mutation clearly did better in terms of progression-free survival being not reached in first-line treatment compared to 22 months progression-free survival in those patients with first-line [treatment] with a P53 mutation. As well as in the relapsed refractory setting, the PFS without the P53 mutation was 47 months versus 21 months with the mutation. However, when you look at these patients treated with ibrutinib and venetoclax comparing whether they got treated in first line or the relapse refractory setting, the overall response rates are very similar at about 80% to 90% and the CR rates were very similar at about 55% to 58%, which to me suggests that although patients with P53 mutation do worse than those without it, whether they're treated in the first-line or the relapse setting with this combination of venetoclax, they tend to do somewhat similar, suggesting that you can overcome resistance to prior therapy in the relapse setting. So I think further data are certainly warranted to explore the role of combination therapies that include novel agents such as BTK inhibitors in the first line setting.  It's worth noting that the TRIANGLE study was recently published, and this study looked at including ibrutinib at various phases, including at induction in combination with intensive chemotherapy and during the maintenance phase. And that study showed encouraging outcomes in patients who received ibrutinib even without stem cell transplant compared to those who received stem cell transplant. So the role of BTKIs in mantle cell lymphoma is certainly evolving, and I think it offers a very effective intervention without the same kind of toxicities we see with cytotoxic chemotherapy that's traditionally used in mantle cell lymphoma. But I think the subgroup of patients with P53 mutation in this disease still represent an area of unmet need that unfortunately have worse outcomes. But novel agents may be able to overcome some of those adverse outcomes. Dr. John Sweetenham: Yeah, I agree. I think these are intriguing data, and obviously it needs more follow-up and probably more prospective studies. But nevertheless, I think there are some signals there for sure that need to be followed up on.  Marc, as always, it's great to have your insights on key advances in the heme space from ASCO.

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

In the relentless battle against non-small cell lung cancer (NSCLC) driven by epidermal growth factor receptor (EGFR) mutations, the development of resistance has long been a formidable obstacle. Historically, first- and second-generation EGFR tyrosine kinase inhibitors (TKIs) like gefitinib, erlotinib, afatinib, and dacomitinib have faced a significant hurdle: the emergence of the T790M point mutation in approximately 50% of patients, rendering the tumor resistant to these therapies. This resistance stems from a sobering reality – before treatment, a small subset of cancer cells already harbor the T790M mutation, conferring no selective advantage initially. However, once treatment commences, these rare mutated cells proliferate selectively, eventually dominating the tumor population and diminishing the effectiveness of first- and second-generation TKIs.

In the first episode of a special daily series during the 2024 ASCO Annual Meeting, Dr. John Sweetenham shares highlights from Day 1, including exciting data on the CROWN trial in NSCLC, the ASC4First study in chronic myeloid leukemia, and the effects of high-deductible health plans on cancer survivorship. TRANSCRIPT Dr. John Sweetenham: I'm Dr. John Sweetenham, the host of the ASCO Daily News Podcast. I'm delighted to bring you a special series of daily episodes from the 2024 ASCO Annual Meeting and to share my top takeaways on selected abstracts.   Today, I'll be reviewing exciting new data in chronic myeloid leukemia, remarkable outcomes for patients with ALK-positive non-small cell lung cancer, and a compelling study on the effects of high deductible health plans on cancer survivorship.   My disclosures are available in the transcript of this episode.   LBA6500, the ASC4FIRST trial, is a phase 3 combination of asciminib with the current standard of care tyrosine kinase inhibitors, those being imatinib, nilotinib, dasatinib and bosutinib for the first line treatment of patients with chronic myeloid leukemia. The data from this large multinational study, conducted in 29 countries, were presented by Dr. Timothy Hughes from the Royal Adelaide Hospital in Australia. Some patients with chronic phase CML respond well to tyrosine kinase inhibitor therapy, and about one-third may eventually be able to stop therapy and will remain in remission, the so-called treatment free remission or TFR. Unfortunately, almost half of patients eventually need to change therapy due to resistance and intolerance, and most patients will need to remain on therapy for many years, possibly for life.  Asciminib is the first BCR-ABL1 inhibitor to specifically target the ABL myristate pocket or STAMP and was designed to be highly potent but also highly specific, thus minimizing side effects and toxicity. In this large trial, which is the first randomized head-to-head comparison of asciminib with other tyrosine kinase inhibitors, 405 patients were randomized 1:1 to receive either asciminib at a dose of 80 milligrams daily or another investigator-selected TKI. The groups were well balanced for all patient characteristics, including ELTS risk. The primary objectives of the study were to compare the major molecular response rate at 48 weeks with an additional analysis for the patients who received imatinib as the investigator-selected TKI. With median follow-up at 16.3 months for patients receiving asciminib and 15.7 months for those receiving the other TKIs, the 48-week MMR rates were 68% for asciminib compared with 49% for the other investigators-selected TKIs.  The rates of MR4 after 48 weeks, a deep molecular response which is a prerequisite to be considered for treatment free remission, were 39% for asciminib compared to 21% for the investigator-selected TKI. Tolerability and safety were excellent for asciminib, with only 5% discontinued due to toxicity compared to 10% for the other TKI arm. Frequently observed toxicities with asciminib included thrombocytopenia and neutropenia. The investigators concluded that asciminib is the only agent to show a statistically significant improvement in efficacy and toxicity in this patient group when compared with all other TKIs, and that asciminib has the potential to become the preferred standard of care for the first line treatment of CML. Follow-up on the study continues, but there is no question that these are exciting and probably practice-changing results.  The next exciting study, LBA8503, was presented by Dr. Benjamin Solomon from the Peter MacCallum Cancer Centre in Melbourne, Australia. This presentation was an update of the CROWN study for patients with previously untreated advanced ALK-positive non-small cell lung cancer. Lorlatinib is a third-generation brain-penetrating ALK inhibitor which was compared with crizotinib in the CROWN-3 study. This phase 3 study enrolled 296 patients randomly assigned to lorlatinib 100 milligrams once daily or crizotinib 250 milligrams twice daily. The interim results showed a 72% reduction in the risk for progression or death with lorlatinib compared with crizotinib and formed the basis for the March 2021 FDA approval of the drug for metastatic ALK positive non-small cell lung cancer. A subsequent post hoc analysis at three years showed continued progression free survival benefit with lorlatinib compared with crizotinib.  Earlier today, Dr. Solomon presented a further post hoc analysis of the study at 60.2 months of median follow-up. Among the entire patient population, the median PFS was not reached with lorlatinib compared with 9.1 months with crizotinib. At 60 months, the PFS rate was 60% with lorlatinib compared with only 8% with crizotinib. The PSF benefits with lorlatinib were seen across all patient subgroups. The improved control of central nervous system metastatic disease, which was observed in the earlier reports, has been confirmed in this recent analysis. Among those patients with baseline brain metastases, the median PFS with lorlatinib was not yet reached compared with six months with crizotinib. More than half of patients with baseline brain metastases were progression free at 60 months.   But the benefit of lorlatinib is certainly not confined to patients with brain metastases. Lorlatinib also significantly improved progression-free survival among patients without metastases. At 60 months, 63% of patients without baseline brain metastases assigned to lorlatinib were progression free, compared with only 10% of those assigned crizotinib. These are remarkable results. As Dr. Solomon stated in his conclusion, 60% of patients on lorlatinib are still progression free and 92% are progression free in the brain. No new safety signals were seen and the improved efficacy over crizotinib was seen across all risk groups. These results are unprecedented in patients with ALK-positive non-small cell lung cancer.   Concerning data were presented today by Dr. Justin Barnes from Washington University. Dr. Barnes presented results from a retrospective study in Abstract 11005 which showed whether a patient with cancer has high-deductible health insurance can play a role in their survival. Although previous studies have shown care disparities for those with high-deductible plans, this report focuses specifically on effects on survival and concludes that cancer survivors with high-deductible health plans had a greater risk of mortality both overall and from cancer. High-deductible insurance was defined as costing between $1,200 and $1,350 annually for individual insurance, or between $2,400 and $2,700 annually for a family plan. Investigators used data from the U.S. National Center for Health Statistics National Health Interview Survey and linked them to files from the National Death Index to determine mortality rates. Included were more than 147,000 respondents aged between 18 and 84 years who did not have Medicaid. Among these individuals, 5.9% were cancer survivors. The concern for cancer survivors with these plans is that in addition to recurrence that could require costly treatments, there might be issues related to survivorship. Investigators found that overall survival was worse for those with a cancer diagnosis coupled with high-deductible health insurance, with a hazard ratio of nearly 1.5.   But when the researchers reviewed data from the general population without a history of cancer, they didn't find any association between high-deductible health insurance and outcomes. According to Dr. Barnes, the leading hypothesis is that patients with cancer who have a high-deductible plan delay workup for a potential new or recurrent cancer diagnosis or postpone or avoid other care. The results also indicated that survival among certain subgroups, such as non-Hispanic white patients, patients with higher incomes, and patients with at least a college or high school education, was worse for those with a high-deductible health plan, not the groups who are typically impacted by care disparities. It is possible that these individuals are more likely to select high-deductible health plans and that having these plans might counteract what might otherwise be adequate access to care.  A key take-home from this analysis is that cancer patients and survivors, whatever their racial, ethnic, or socioeconomic status, should have access to health plans with low deductibles and should be informed of the potential risks of their long-term health and survival when covered by high-deductible plans.   Join me again tomorrow to hear more top takeaways from ASCO24.

Dr. Jyoti Patel discusses the latest update to the stage IV NSCLC with driver alterations living guideline, specifically for patients with EGFR or ROS1 alterations. She shares the latest recommendations based on recently published evidence, such as the FLAURA2, MARIPOSA-2, and TRIDENT-1 trials. Dr. Patel talks about how to choose between these new options and the impact for patients living with stage IV NSCLC, as well as novel drugs the panel is monitoring for future guideline updates. Read the full living guideline update “Therapy for Stage IV Non-Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2024.1” at www.asco.org/living-guidelines. TRANSCRIPT This guideline, clinical tools, and resources are available at 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.24.00762  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. Jyoti Patel from Northwestern University, co-chair on, “Therapy for Stage IV Non-Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2024.1.”  Thank you for being here today, Dr. Patel. Dr. Jyoti Patel: Thanks so much.   Brittany Harvey: 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 in the Journal of Clinical Oncology, which is linked in the show notes.  So then to dive into the content of why we're here today, Dr. Patel, this living clinical practice guideline for systemic therapy for patients with stage four non-small cell lung cancer with driver alterations is being updated on a regular basis. So what prompted the update to the recommendations in this latest update?  Dr. Jyoti Patel: This recent update, I think, absolutely reflects how quickly the science is changing. The landscape of treatment options for patients with advanced non-small cell lung cancer is evolving so rapidly, and guidelines from even six months ago don't address some of the newest approvals and newest data and the newest clinical scenarios that we're presented with when we see patients. I think it's harder because before there was usually a single answer, and now there are a number of scenarios, and we hope that the guideline addresses this. Brittany Harvey: Absolutely. The panel's had a lot of data to review as you keep this guideline up to date.  So then this latest update addresses updates to both EGFR and ROS1 alterations. So starting with EGFR, what are the updated recommendations for patients with stage four non-small cell lung cancer and an EGFR exon 19 deletion or exon 21 L858R substitution?  Dr. Jyoti Patel: So for patients with classical driver mutations in EGFR, our recommendation remains that patients should be offered osimertinib. We now also have data to support intensification of therapy with osimertinib and chemotherapy. The FLAURA2 trial was a global randomized study in which patients with classical mutations were assigned to receive either osimertinib or osimertinib with doublet chemotherapy. The trial showed that progression free survival was longer with osimertinib plus chemotherapy with a hazard ratio that was pretty profound, 0.62. In patients who had CNS metastasis as well as patients with L858R mutations, this benefit remained and was perhaps even greater. Now the study remains immature in terms of OS. What we can say is that chemotherapy adds toxicity, so the inconvenience of 13 weekly infusions, expected toxicities from chemotherapy of myelosuppression and fatigue. I think this- we'll continue to watch as the study matures to really see the OS benefit, but certainly intensification in the frontline setting is an option for patients.  The other major update was for second and subsequent line therapy for these patients with EGFR mutations. Another important trial, a study called MARIPOSA-2, was published in the interim, and this was for patients who had received osimertinib in the frontline setting. Patients were randomized to one of three arms. The two arms that are most relevant for us to discuss are chemotherapy with amivantamab or chemotherapy alone. Chemotherapy with amivantamab was associated with an improvement in progression free survival with a hazard ratio of 0.48 as well as improvements in response rate with almost a doubling of response rate to the mid 60%. There was certainly an increase in AEs associated with amivantamab, primarily rash and lower extremity edema and importantly infusion reaction. Based on this data, though in the superior PFS and response rate, we've said that patients after osimertinib should be offered chemotherapy plus amivantamab. Patients may opt for chemotherapy alone because of the toxicity profile, but this recent update is reflective of that data. Brittany Harvey: Excellent. Thank you for reviewing those updated recommendations and the supporting evidence behind those recommendations. I think that's important to the nuance and the toxicity associated with these new recommendations as well.   So then, following those recommendations, what are the updated recommendations for patients with stage four non-small cell lung cancer and a ROS1 rearrangement? Dr. Jyoti Patel: ROS1 fusions have been noted in a small but important subset of patients. We now reflect multiple new options for patients. Traditionally, crizotinib was the primary drug that was recommended, but we now have two very active drugs, repotrectinib, and entrectinib, that have both been FDA approved. Repotrectinib was approved based on a study called the TRIDENT-1 trial. In this study, patients who were treatment naive, who had not received a prior TKI, had a response rate of 79% and a long duration of response over 34 months. For patients who had received prior TKIs, so primarily crizotinib, the response rate was lower at 38%. But again, very clinically meaningful. Repotrectinib has known CNS activity, so it would be the favored drug over crizotinib, which doesn't have CNS penetration. The decision between entrectinib and repotrectinib is one, I think, based on toxicity. Repotrectinib can cause things like dizziness and hypotension. Entrectinib can cause weight gain, and also has CNS effects. Brittany Harvey: Appreciate you reviewing those recommendations as well.  So then you've already talked a little bit about this in terms of deciding between some of the options. But in your view, what should clinicians know as they implement these new recommendations, and how do these new recommendations fit into the previous recommendations? Dr. Jyoti Patel: So there's an onslaught of new data, and certainly many of us want to remain at the front of our fields and prescribe the newest drug, our most effective drug, to all of our patients. But for the person living with cancer and in the practice of medicine, I think it's much more nuanced than that. For example, for a patient with an EGFR mutation exon deletion 19, the expectation is that osimertinib will have a deep and durable response. Certainly a patient will eventually have progression. I think the decision about intensification of therapy and chemotherapy on the onset really has to do with how much the patient is willing to deal with the inconvenience of ongoing chemotherapy, the uncertainty about what comes next after progression on chemotherapy. It may be, though, that a patient may very much fear progressive disease, and so that inconvenience is lessened because anxiety around feeling like they're doing everything for their cancer is diminished by intensification of therapy. Others who may have a large volume of disease or profoundly symptomatic, or who have L858R or brain metastasis it may make sense to give chemotherapy again, we're improving the time until progression significantly by combination therapy. Brittany Harvey: Definitely those nuances are important as we think about which options that patients should receive, along with shared decision making as well.  So then what do these new options mean for patients with EGFR or ROS1 alterations? Dr. Jyoti Patel: It's fantastic for patients that there are multiple options. It's also really hard for patients that there are multiple options, because then again, we have to really clarify aims of therapy, identify what's really important in patient experience and the lived importance of treatment delivery and the burden of treatment delivery. Now more than ever, oncologists have to know what's new and exciting. But patients have to be willing to ask and participate in the shared decision making - understanding their cancer and understanding that their options are absolutely important. As patients start making their decisions, we have the data just in terms of trial outcomes. I think we're now trying to understand the burden of treatment for patients. And so that piece of communicating financial toxicity, long term cumulative lower grade toxicity is going to be more important than ever. Brittany Harvey: Absolutely. It's great to have these new options, and those elements of communication are key to ensuring that patients meet their goals of care.  So then finally, as this is a living guideline, what ongoing research is the panel monitoring for future updates to these recommendations for patients with stage four non-small cell lung cancer with driver alterations? Dr. Jyoti Patel: It's certainly been an exciting time, and that's primarily because we've been able to build on years of foundational science and we have new drugs. Patients have been willing to volunteer to go on clinical trials and to think about what treatment options may be best. Now, the work really comes on seeing the longer term outcomes from these trials. So looking at these trials for overall survival, we want to also better identify which patients will benefit the most from these treatments and so that might be additional biomarker analysis. So it may be that we can identify patients that may need intensification of therapy based on tumor factors as well as patient factors as well in those patients in whom we can de-escalate treatment. I think there are a number of new compounds that are in the pipeline. So fourth generation EGFR TKIs are certainly interesting. They may be able to overcome resistance for a subset of patients who progress on osimertinib. We also think about novel drugs such as antibody drug conjugates and how they'll fit into our paradigm with osimertinib or after carboplatin-based doublets. Brittany Harvey: Definitely. We'll look forward to both longer term readouts from the current trials and new trials in this field to look at additional options for patients.  So I want to thank you so much for your time today, Dr. Patel, and thank you for all of your work to keep this living guideline up to date. Dr. Jyoti Patel: Great. Thanks so much, Brittany. It really is an exciting time for people who treat lung cancer and for patients who have lung cancer. We certainly have a long way to go, but certainly the rapid uptake of these guidelines reflect the progress that's being made.  Brittany Harvey: Absolutely.

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

Dr. John Sweetenham and Dr. Marc Braunstein look ahead at key abstracts across the spectrum of hematologic malignancies that will be presented at the 2024 ASCO Annual Meeting, including the OPTIC trial in chronic myeloid leukemia, treatment options for transplant-ineligible patients with multiple myeloma, and the 7-year analysis of the ECHELON-1 trial in classical Hodgkin lymphoma. TRANSCRIPT Dr. John Sweetenham: Hello, I'm Dr. John Sweetenham from UT Southwestern's Harold C. Simmons Comprehensive Cancer Center and the host of the ASCO Daily News Podcast. I'm delighted to be joined again this year by Dr. Marc Braunstein, a hematologist and oncologist at the NYU Perlmutter Cancer Center in New York. We're going to be discussing some of the key abstracts in hematologic malignancies that will be featured at the 2024 ASCO Annual Meeting.  Our full disclosures are available in the transcript of this episode, and disclosures of all guests on the podcast are available at asco.org/DNpod.  Marc, it's great to have you back on the podcast. Dr. Marc Braunstein: It's a pleasure to be back, John.  Dr. John Sweetenham: There are some exciting abstracts to be presented at this year's meeting, and I would like to begin, if we can, with Abstract 6501. As you know, this reports the four-year results from the OPTIC trial of ponatinib in patients with chronic-phase CML and the T315I mutation. Can you tell us about the trial and about these latest follow-up results? Dr. Marc Braunstein: Sure. Well, we've made tremendous progress in managing patients with CML in the past two decades using these oral tyrosine kinase inhibitors such as ponatinib. Ponatinib is a third-generation TKI that has activity in both Philadelphia-positive ALL as well as CML, and can overcome the resistance mutation you mentioned, called the T315I mutation, which is sometimes found following prior TKI therapy. The OPTIC study is a multicenter phase 2 randomized study of various doses of ponatinib in 283 chronic phase CML patients who had received 2 or more prior lines of therapy or those who had the presence of a T315I mutation, with the current analysis examining the major remission at 48 months, PFS, as well as OS. Of note, in this study, after patients have achieved a major remission with a transcript level of 1% or less, the study allowed for dose reduction of ponatinib from the original dose of either 45 milligrams or 30 milligrams to a reduced dose of 15 milligrams.  So, when we look at the results, we find that the patients who had the highest overall response rates and higher rates of molecular remission were those who received the 45-milligram dose. And remember, these patients were allowed to be dose-reduced to the 15-milligram dose once they achieved a molecular remission of 1% or less. In addition, the rates of overall survival were highest in the 45-milligram dose as well. When looking at the T315I subgroup, the rates of molecular remission, the depth of remission, and the rates of progression-free survival, in general, were lower in that subgroup, but still higher in the 45-milligram dose than the 35- milligram dose.  Furthermore, when looking at the rates of treatment-emergent adverse events leading to discontinuation, they were 8% in the 45-milligram dose compared to 14% in the 30-milligram dose and 5% in the patients who only received the 15-milligram dose. The authors have concluded that the 45-milligram dose, with the potential to be reduced to 15 milligrams after achieving 1% or less of the BCR-ABL transcript level, seems to be the right balance between efficacy and safety.  Dr. John Sweetenham: Thanks, Marc. In the longer term, do you think that this study will, in any way, affect the position of ponatinib in the treatment algorithm for CML? Is it going to remain as a second or third-line option, or do you think there's any chance it will be moved up? Dr. Marc Braunstein: Well, that's a great question. There are other TKIs, such as asciminib, that also target the T315I mutation, and that mutation tends to develop after prior first-line or second-line TKI therapy. But given its activity in both ALL and CML, I think it's certainly reasonable to expect that ponatinib will be used in earlier lines of therapy given its efficacy in later lines. Dr. John Sweetenham: Let's change gears and move the focus to acute myeloid leukemia. There has been a lot of discussion around frailty in many different malignancies, but the impact of frailty on outcomes in AML is maybe something that hasn't been quite so well studied. In Abstract 6506, investigators did a population-based study in Ontario, Canada, that assessed the patient's frailty risk and the impact that might have on outcomes. What are your takeaways from this study, and how do you think these data will help optimize treatment decisions?  Dr. Marc Braunstein: Yeah, I'm glad we're talking about this abstract John, because frailty scores are increasingly being used in hematologic malignancies to help guide goals and intensity of care. And as opposed to using age or performance status alone, these composite frailty assessment tools, such as the MFI tool that they used in this particular study, take into account multiple variables that are both physiologic, such as the patient's comorbidities, as well as social, and what kind of support system do they have, and things of that nature. And that accounts for their overall fitness. So, in this retrospective cohort study that was a population-based study in Ontario between 2006 and 2021, they looked at 5,450 patients retrospectively with acute leukemia and grouped those patients into 3 categories based on this frailty index. Patients who are either fit, somewhere in the middle between fit or frail, which they call pre-frail, or frail. And they looked at outcomes such as overall survival, comparing patients who got intensive chemotherapy regimens for induction or those who got non-intensive therapy for induction. Patients in either group could have been assigned to either fit, pre-frail, or frail although there are much more fit patients than those who got intensive induction.  And so, looking at their findings, it was noted that patients who were in the frail category, not entirely unexpectedly, had lower overall survival when compared to those who were fit or pre-frail. I think the value of a study like this is not just to highlight the benefit of frailty scores to help predict which patients may ultimately have a shorter survival, but also to help potentially guide which patients may be more suitable for intensive versus less intensive induction. I will note that this study was conducted in an era where we didn't have the same sorts of less intensive induction that are very effective in less fit patients, such as the combination of azacytidine and venetoclax, which is commonly used in less fit patients nowadays. So, the study may encompass patients who didn't have access to that therapy because it wasn't available during that time. But I think it still, overall, does highlight the fact that assessing fitness or frailty in acute myeloid leukemia is important for predictive value. Dr. John Sweetenham: I agree. Marc, I don't know what your thoughts are on this, but it goes either way. I mean, I think that, if I remember the numbers correctly, 25% of fit patients received non-intensive therapy. So, is there a missed opportunity there for that group of patients who actually may have tolerated the intensive therapy but it was never offered? Dr. Marc Braunstein: That's an excellent point, John, and I think that highlights the importance of frailty indices because they take into account much more than one particular factor, or even just a subjective assessment of the patient in real time when they're first presenting. And they may have disease-specific features that are decreasing, say one element of their assessment such as their performance status. So, really taking these composite fitness scores into account may actually allow you to escalate therapy in a patient who may actually be fit but maybe perceived as less fit when they present. Dr. John Sweetenham: Yeah. So, I think, as you mentioned, there are better treatment options out there now maybe than there were at the time this study was conducted. Nevertheless, there may still be that opportunity for more intensive therapy for some of these patients when they are more holistically assessed.  Let's move on and switch gears once again and talk about a study in multiple myeloma, the so-called IMROZ study, which is Abstract 7500. So, this is a study looking at treatment options for transplant-ineligible patients with newly diagnosed multiple myeloma. Some of these patients may not have a chance for subsequent therapy if they are not eligible for transplant. What are your thoughts on this study? Do you think we're closer to a new standard of care for patients who are not going to proceed to an autologous stem cell transplant?  Dr. Marc Braunstein: It seems like every year there's a new standard of care for newly diagnosed multiple myeloma because there's so much data emerging, which is just wonderful. So, I think as background, at the 2023 ASH meeting, the IsKia study was presented, which is a randomized phase 3 study in newly diagnosed transplant-eligible patients. And that was using isatuximab with carfilzomib, lenalidomide, and dexamethasone upfront and that study did show a benefit in terms of reducing minimal residual disease compared to carfilzomib, lenalidomide, and dexamethasone alone. But that study was looking at fit newly diagnosed patients who were going on to stem cell transplant. Right now, the standard of care for patients who are not eligible for transplant is generally to use a 2 or 3-drug regimen, such as daratumumab, lenalidomide, and dexamethasone, based on the phase 3 MAYA study. But this study is really unique in that it looks at using a quadruplet regimen in patients who are transplant ineligible or not intended to go for transplant.  So, the phase 3 IMROZ study was a randomized study of 446 patients that compared isatuximab, bortezomib, lenalidomide, and dexamethasone to bortezomib, lenalidomide, and dexamethasone alone. So, a quad versus a triplet regimen. The primary endpoint in this study was progression-free survival, but they also looked at secondary endpoints, such as complete response rate and minimal residual disease negativity.   Just to quickly highlight the results and then discuss the standard of care, the median duration of treatment in this study was 53 months in the quad regimen and 31 months in the control arm. At a median follow-up of about 60 months, the progression-free survival was not reached with the quad regimen versus 54 months in the triplet, and that was a significant difference. In addition, the safety profile was pretty much consistent with the class, there were a bit more grade three or higher treatment-emergent adverse events with the ESA-containing regimen, 92% versus 84%, but no difference in adverse events leading to discontinuation in either arm.   So, this study is certainly compelling in terms of using quadruplet-based regimens that contain an anti-CD38 monoclonal antibody for newly diagnosed patients who are not intended to undergo transplant. I think at the meeting, I will be interested to see the patient population that was included. Patients who are over the age of 80, for example, are excluded. So, I would like to know more about their fitness level and performance status. But I think it's clear, John, that using quad regimens over triplet regimens is just consistently superior in terms of efficacy outcomes. Dr. John Sweetenham: Right. I guess that, even though maybe we can't focus on the specific agents right now, it looks as if quad regimens are going to be the standard of care regimens for the future in this group. Do you think that is fair?  Dr. Marc Braunstein: Very likely. Dr. John Sweetenham: Absolutely. Well, that's a pretty challenging group of patients.   And so to move on again, let's talk about another, perhaps equally challenging group - patients with mantle cell lymphoma, particularly those who carry certain mutations. The so-called SYMPATICO study, which is reported in Abstract 7007, presents data on the efficacy and safety of ibrutinib and venetoclax in patients with mantle cell lymphoma who carry a TP53 mutation. We know that this mutation confers a high risk of early progressive disease and poorer outcomes when these patients are treated with standard chemoimmunotherapy for mantle cell. Trials to date have been limited to small single-arm studies. Can you tell us a little bit about this study and the outcomes and what you think it means for the future?  Dr. Marc Braunstein: As a background, although BTK inhibitors such as ibrutinib have yet to be approved for newly diagnosed mantle cell lymphoma, acalabrutinib and zanubrutinib, which are second-generation BTK inhibitors, are FDA-approved for previously treated mantle cell lymphoma. Ibrutinib was withdrawn from the market. The lead author of this abstract, Dr. Michael Wang, had presented a late-breaking data from the phase 3 SYMPATICO trial at ASH last year, in which 267 patients with relapsed or refractory mantle cell lymphoma after one to five prior lines of therapy were randomized to receive the combination of ibrutinib plus the BCL-2 inhibitor venetoclax or ibrutinib plus placebo. That study showed there was a 32 versus 22-month progression-free survival with a hazard ratio of 0.65 at a median follow-up of 51 months, indicating the PFS benefit of the combination of ibrutinib and venetoclax compared to ibrutinib with placebo.   So that leads us to this subgroup analysis in the current study being presented at ASCO, in which they looked at a subgroup of patients with mantle cell lymphoma who are at very high risk for treatment failure and early relapse - those are patients who have a mutation in TP53, which again is high risk for treatment failure. This abstract examined an open-label cohort of 44 first-line patients, as well as 75 patients who were in the relapse/refractory cohort, and compared to patients who either did or did not have the P53 mutation. When we look at the progression-free survival outcomes, the median progression-free survival in the first-line cohort of patients who did not have a P53 mutation was not reached, whereas those with the P53 mutation had a median progression-free survival of 22 months, which is still meaningful but still less than those who did not have a P53 mutation. Which again is not entirely unexpected. But the overall response rate of the combination of ibrutinib and venetoclax was very high at 90%, and the median duration of response was about 21 months.  Now comparing this to the relapse/refractory cohort, in those without a P53 mutation, the progression-free survival of the combination of ibrutinib and venetoclax was about 47 months versus those who don't have the P53 mutation was about 21 months with an overall response rate of 80%. I think one takeaway looking at this comparison of the first-line and relapse/refractory setting is that patients seem to do very similar in terms of overall response rate and progression-free survival, whether they were in the first line or in the later lines of treatment if they had the P53 mutation, which says that the combination of ibrutinib and venetoclax is effective no matter which phase of the disease the patient might be in, indicating its overall activity and being strong.    Dr. John Sweetenham: Yeah, I thought that was an interesting observation, actually, how similar the outcomes were in those two groups.  Dr. Marc Braunstein: No, I agree. And I think although patients with TP53 mutations did comparatively worse than those without the mutation according to progression-free survival, overall response rate, or complete remission rates, they did seem to be similar whether a patient was in first-line or relapsed refractory if they were P53 mutant and were treated with this combination. So, I think we need further data in the first line, such as the data that's awaiting publication from the TRIANGLE study, which is examining upfront ibrutinib. But certainly, BTK inhibitors have significant activity in either the first line or the relapse setting of mantle cell lymphoma.  Dr. John Sweetenham: Great. Thanks, Marc.  Let's wind up with one more abstract, and this is Abstract 7053. It's a 7-year analysis of the so-called ECHELON-1 study. This was a study comparing the standard of care, ABVD, with the same regimen with bleomycin substituted by brentuximab vedotin for patients with previously untreated advanced-stage classical Hodgkin lymphoma. The study at the time it was originally reported, resulted in a significant practice change in the first-line therapy of Hodgkin's lymphoma. We now have mature follow-up. What are your take-homes from this study? Dr. Marc Braunstein: The ECHELON-1 study has certainly been a practice-changing clinical trial where, as you said, brentuximab with the backbone of AVD was compared to ABVD, which was the prior standard. And this was examined in newly diagnosed patients with classical Hodgkin lymphoma who were at advanced-stage, stage 3 or 4. The publication, first of the progression-free survival, and more recently, in the New England Journal of Medicine in 2022, where we saw the 6-year overall survival was 94% with the brentuximab-containing arm versus 89% in the control arm, established the brentuximab AVD, or otherwise called AAVD, as the standard of care in advanced stage newly diagnosed classical Hodgkin lymphoma. The current study is now reporting 7-year follow-up on about 1,300 randomized patients who were enrolled in this impressive study.   Though at a median follow-up of 89 months now, the 7-year overall survival was quite similar, 94% versus 89%, again favoring the brentuximab-containing arm. In particular, this was driven by patients who had stage 4 disease or those patients who were aged less than 60 in subgroup analyses. So, what I take away from this abstract in the 7-year follow-up of the ECHELON-1 is that brentuximab with AVD remains the standard of care for previously untreated advanced-stage classical Hodgkin lymphoma. It is worth noting that the SWOG S1826 study that was presented at ASCO last year compared nivolumab with AVD compared to brentuximab AVD and did show a slight PFS advantage of 94% versus 86% with nivolumab AVD. Obviously, these were different studies with different patient populations enrolled, so we're really just cross-comparing different studies. But I think brentuximab AVD, given the survival benefit that is retained now at seven years in the current abstract, still remains the standard of care for advanced-stage classical Hodgkin lymphoma. The role of immune checkpoint inhibitors like nivolumab is making headway in terms of treating newly diagnosed patients as well. Dr. John Sweetenham: Yeah, thanks, Marc. I mean, one of the observations that I thought was of interest in this study was the outcome for patients who were PET-2 positive, when you compare AAVD and ABVD. It does seem as if even in those patients who are PET-2 positive, having had AAVD, they still apparently have a better outcome than those who received ABVD in that situation who were PET-2 positive. So, I think that's another interesting observation. I'm not quite sure what it means, except speaking to the overall superior efficacy of that regimen. Dr. Marc Braunstein: You make a great point, John, because it's worth noting that in ECHELON-1, a PET scan was done after cycle 2, but the study was not PET-adapted. So even if you had a positive PET, you continued for the full six cycles of treatment. But PET-2 status is often used in various studies of Hodgkin lymphoma to guide whether to give additional cycles or escalate therapy. So, I think the benefit of presenting those subgroups is that even if you were PET-2 positive, you still did better by continuing on the brentuximab-containing regimen. Dr. John Sweetenham: Yeah, exactly. I mean, the other important takeaway message, I think, is that the outcome for patients with advanced Hodgkin lymphoma seems to continue to steadily improve, which is great news and also really remarkable. And I'm excited to see there may be some additional data presented at one of the late-breaking abstracts in this year's meeting, so it will truly be interesting to see what that shows us as well.  Dr. Marc Braunstein: Incredible. Dr. John Sweetenham: Well, Marc, as always, thank you for sharing your insights with us today on the ASCO Daily News Podcast. We look forward very much to hearing the updated data from these abstracts at the meeting.  Dr. Marc Braunstein: As do I and thank you so much for inviting me again.  Dr. John Sweetenham: And thank you to our listeners for joining us today.

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

In this JCO Article Insights episode, Rohit Singh provides summary on two articles published in the April 10th issue of the Journal of Clinical Oncology. The first article, "Phase III, Randomized Study of Atezolizumab Plus Bevacizumab and Chemotherapy in Patients With EGFR- or ALK-Mutated Non–Small-Cell Lung Cancer (ATTLAS, KCSG-LU19-04)" describes a randomized, open-label, multicenter, phase III study evaluating the efficacy of atezolizumab plus bevacizumab, paclitaxel, and carboplatin (ABCP ) in EGFR- or ALK-mutated NSCLC that progressed before TKI therapy. The second is the accompanying Oncology Grand Rounds. TRANSCRIPT The guest on this podcast episode has no disclosures to declare. Dr. Rohit Singh: Hello and welcome to JCO Article Insights. I'm your host, Dr. Rohit Singh. Today I will provide a summary of a Phase III, Randomized Study of Atezolizumab Plus Bevacizumab and Chemotherapy in Patients With EGFR- or ALK-Mutated Non–Small-Cell Lung Cancer (ATTLAS, KCSG-LU19-04), by Dr. Park and colleagues from Seoul, Korea. The purpose of this study was to evaluate the efficacy and safety of the ABCP regimen based on IMpower150 in patients with EGFR or ALK mutated non-small cell lung cancer who had progressed on prior targeted treatment.   I will also discuss an Oncology Grand Round case titled "Management of Treatment Resistance in Patients with Advanced EGFR Lung Cancer: Personalization, Parsimony, and Partnership", by Dr. Vallillo and colleagues from Lahey Hospital Medical Center and Tufts University School of Medicine, Boston, Massachusetts. Oncology Grand Round cases help us to give a clinical context to the clinical trial.   While TKIs are the established standard of care for non-small cell lung cancer harboring driver mutations, most patients will develop resistance to these treatments. Immune checkpoint inhibitors, with or without chemo, have shown clinical benefits of immune checkpoint monotherapy in patients with EGFR-mutated non-small cell lung cancer. Consequently, platinum-based chemo is the standard of care for patients with EGFR TKI failure. This was a phase III, multicenter, open-label, randomized trial conducted at 16 hospitals across the Republic of Korea. Patients diagnosed with stage four non-small cell lung cancer with sensitizing EGFR mutation or ALK translocation were included in the study. Patients were randomly assigned to the ABCP arm or chemo-only arm in a 2:1 ratio. Eligible patients were stratified on the mutation type (EGFR mutation vs. ALK translocation) and the presence of brain metastasis. No crossover to atezolizumab was permitted.  The recruitment with T790M mutation was capped at 30%. Patients who responded continued to receive maintenance with atezolizumab until disease progression or unacceptable toxicities occurred. If a patient was identified to have an acquired T790M mutation after the failure of a first or second-generation EGFR TKI, the patient had to be treated with a third-generation EGFR TKI before enrollment. The primary endpoint was investigator-assessed objective response rate according to research criteria. The secondary endpoints included overall survival and progression-free survival at one and two years, and the duration of response, along with a safety analysis. Investigators also did an exploratory biomarker analysis based on PD-L1 expression and its correlation with the response. They also analyzed the distribution of tumor-infiltrating lymphocytes, and a cut-off of 20% inflamed score was used to compare the two arms. Overall, 228 patients were enrolled, 154 in the ABCP arm and 74 in the chemo-only arm. Most patients were female at 56.1% and never smokers at 62.7%. Brain metastasis was present in 42.7% of patients. Most patients had previously received EGFR TKI therapy, however, only 8% and 30% received third-generation TKI as first-line therapy in the ABCP arm and  chemo-only arm, respectively. The majority of the patients were EGFR at  90%.  The median duration of follow-up for the study population was 26 months. The objective response rate in the ABCP arm was significantly higher at 69.5% compared to 42% in the chemotherapy alone arm. The median PFS was significantly longer in the ABCP arm at 8.48 months versus 5.6 months, and the duration of response was similar at around seven months in both arms. The median overall survival was also similar at around 20 months in both arms, with a hazard ratio of 1.01. In the subgroup of patients with brain metastasis at the time of study enrollment, PFS was significantly longer in the ABCP arm at 8.4 months compared to 4.4 months in the chemotherapy-only arm. In contrast, no difference in PFS was observed in the subgroup without brain metastasis. Regarding EGFR mutation status, there was no difference in PFS or OS between the two arms in the EGFR deletion 19 subgroup. However, a favorable PFS was observed in the EGFR L858R subgroup. For those with acquired EGFR T790M mutation, there was no difference in PFS between groups, whereas a favorable PFS was observed in the subgroup without EGFR T790M mutation.  In the exploratory biomarker analysis, interestingly, the impact on PFS was correlated with PD-L1 expression. The study found that the higher the PD-L1 expression, the better the PFS. In patients with PD-L1 expression of more than 50%, the hazard ratio was 0.24 for PFS. This is an interesting observation. As in previous studies, we have seen that PD-L1 expression does not have a strong association with response to checkpoint inhibitors in patients with driver mutations. Based on the distribution density of tails in the tumor bed, the inflamed score was calculated using artificial intelligence. For patients with 20% of the imflamed score, the ABCP arm has significantly prolonged PFS at 12.9 months compared to 4.8 months. The median number of ABCP treatment cycles was 4, with 12 for atezolizumab and 8 for bevacizumab as maintenance therapy, pemetrexed maintenance was administered for a median of 10 cycles. The incidence of grade 3 or higher side effects was 35.1% in the ABCP arm compared to 15% in the chemotherapy-only arm. Peripheral neuropathy, alopecia, and myalgias were the most prevalent side effects. Interesting notably, 54% of patients in the ABCP arm required treatment interruption or dose modification, and there were three reported deaths in the ABCP arm, two due to pneumonia and one due to cerebral embolic infarction. Around 10 patients or 13.5% of patients in the chemotherapy-only arm required dose interruption or modification.   In conclusion, patients with EGFR-mutated or translocated non-small cell lung cancer who had failed prior TKI ABCP regimen showed a statistically significant prolongation of PFS and response rate compared to chemo alone. Patients in the subgroup with EGFR L858R, without acquired T790M mutation, and presence of brain met showed more benefit. There was no difference in overall survival, though we need more mature data. Adverse events were higher in the ABCP arm. Interestingly, in the exploratory analysis, a high PD-L1 and an inflamed score of more than 20% showed PFS benefits. Though we need to take into consideration that this trial was done and all the patients were grouped from a single country considering Asian ethnicity. And most importantly, the majority of patients were treated with first- and second-generation TKIs, whereas third-generation TKIs are the standard of care in the United States.  Coming to the Oncology Grand Round, in this case, we will discuss the management of treatment resistance in patients with advanced EGFR-mutated lung cancer. A patient with a 20-pack-a-year history of tobacco use presents with weight loss and hip pain, found to have a lung mass, skeletal mets, and brain mets, and was diagnosed with lung adenocarcinoma. The patient goes with palliative radiotherapy for the brain mets. Comprehensive tumor Merkel profiling demonstrated an EGFR mutation exon 19 and alteration P53. The patient was started on third-generation EGFR TKI osimertinib. However, after 17 months, the patient has symptomatic disease progression. Usual approach, if feasible, re-biopsy at the time of progression to evaluate for possible new mutations which can guide treatment options. As mentioned earlier, in the trial, acquired resistance to the TKI is inevitable and heterogeneous. There were various mechanisms which have been proposed regarding resistance, including a second-site EGFR alteration, upregulation of bypass pathway, histological transformation to small cell histology, or suboptimal drug penetration.  There are various approaches after disease progression on EGFR TKI. Combining EGFR-directed therapies to address resistance is an option. Prime results from the MARIPOSA-2 study showed amivantamab plus chemotherapy with or without lazertinib in EGFR-mutated non-small cell lung cancer after disease progression showed a better objective response rate at 64% compared to 36% in the chemo-alone arm. It also showed improved PFS with a median of 6.3 compared to 4.2 in the chemo-alone arm. Combining immune checkpoint inhibitors, EGFR-mutated non-small cell lung, I say has been disappointing in advance of EGFR-mutated non-small cell lung, and combination therapy studies are needed to improve outcomes. Studies, as I discussed ATTLAS, have shown that combining a VEGF inhibitor with ICIs and chemotherapy can lead to a better objective response rate and PFS. However, further clinical trials are needed to figure out the better subgroup of patients who can benefit from this combination.   Should the TKI be continued beyond progression in EGFR-mutated advanced non-small cell lung cancer? Continuing the primary EGFR TKI treatment beyond progression may be considered for patients with indolent or asymptomatic progression or localized progression. We can consider radiation, surgery, or ablation. This approach will potentially delay the need to change systemic therapy in patients. However, for patients with multifocal disease progression requiring chain systemic therapy it may be more beneficial to switch to next-line systemic therapy options like platinum doublet with or without immunotherapy and VEGF inhibitors. In the case presented, the decision was made to continue osimertinib along with platinum doublet, deferring the addition of immunotherapy and VEGF inhibitor. This choice was based on factors like the patient's history of brain metastases and intracranial control. There is also a high risk of toxicity, especially pneumonitis, with immune checkpoint inhibitors after using targeted therapy, the patient showed clinical and radiographic improvement while on this treatment regimen.  The decision to continue or change therapy at cancer progression is based on factors like drug tolerability, patient preferences, and specific subgroups with different outcomes, such as those with brain metastasis or specific EGFR mutation subtypes. Choosing between combination therapy strategies that concept progression involves personalized decision-making to optimize treatment outcomes. Ultimately, the approach to management should be tailored to individual patient needs, preferences, and eligibility for different treatment modalities.  This is Rohit Singh.

Based on the latest Novartis Earnings Call that took place on April 23, 2024, the company has provided insights into their strategic positioning and overall direction, specifically in relation to their role in the chronic myeloid leukemia (CML) treatment market. During the call, CEO Dr. Vasant Narasimhan revealed an optimistic outlook for Novartis's progress, projecting that the company could perform at almost three times the level of a previous launch. This projection is based on Novartis's prior success navigating the complex cancer treatment landscape and the established popularity of their drug, Gleevec. With a two-thirds market share of first-line treatments for CML, Gleevec's effectiveness as a tyrosine kinase inhibitor (TKI) has made it a linchpin in Novartis's treatment portfolio.The company also acknowledged that patients often face challenges accessing second-generation TKIs due to systemic barriers. In response to this, Novartis introduced a new drug, Scemblix, backed by a strong patent estate and comprehensive data set. As stated on the earnings call, Scemblix is positioned as a first alternative for CML patients with access issues, marking Novartis's strategic move to drive growth and extend their market impact.Furthermore, as revealed in the call, Novartis is not limited to focusing on third-line treatments. The company plans to strengthen its presence in second-line treatments also. Discussing potential uptake, Dr. Narasimhan observed, "We would expect, I would say, a modest early uptake because we would have to work through -- CML is one of the few cancer areas that's currently contracted. ... we believe that given the overall data set that we'll share at ASCO that it should be able to drive very strong uptake." This perspective illustrates Novartis's aim to reach more of the CML treatment community.Additionally, Medicare's exclusion from Novartis's lifecycle management agreements was signaled out on the call, representing a strategic move that could significantly shape CML treatment options. This exclusion opens up additional treatment possibilities beyond generic imatinib for a sizeable group of CML patients, highlighting yet another way Novartis anticipates influencing the market dynamics of CML treatments.In summary, Novartis's earnings call outlined several strategic considerations, including tackling access problems, exploring new market segments, and solidifying their product lineup. These efforts demonstrate Novartis's focused attempt to maintain and potentially enhance their role within the CML treatment spectrum, albeit tempered by the reality of the unknown complexities within the healthcare landscape.

BUFFALO, NY- March 19, 2024 – A new #research perspective was #published by Mikhail V. Blagosklonny M.D., Ph.D., from Roswell Park Comprehensive Cancer Center in Oncotarget's Volume 15 on March 15, 2024, entitled, “From osimertinib to preemptive combinations.” “Here, I suggest that while first-line osimertinib extends median progression-free survival (PFS) in EGFR-mutant lung cancer compared to first-generation TKIs, it reduces individual PFS in 15–20% of patients compared to first-generation TKIs. Since detecting a single resistant cell before treatment is usually impossible, osimertinib must be used in all patients as a first-line treatment, raising median PFS overall but harming some. The simplest remedy is a preemptive combination (PC) of osimertinib and gefitinib. A comprehensive PC (osimertinib, afatinib/gefitinib, and capmatinib) could dramatically increase PFS for 80% of patients compared to osimertinib alone, without harming anyone. This article also explores PCs for MET-driven lung cancer.” DOI - https://doi.org/10.18632/oncotarget.28569 Correspondence to - Mikhail V.

Dr. Natash Leighl and Dr. Jyoti Patel are back on the podcast to discuss the update to the living guideline on stage IV NSCLC with driver alterations. This guideline includes recommendations for first-, second-, and subsequent-line therapy for patients with driver alterations including: EGFR, ALK, ROS1, BRAFV600E, MET exon skipping mutation, RET rearrangement, NTRK rearrangement, HER2, and KRAS G12C. They highlight the key changes to the recommendations, addition of recent trials, the importance of biomarker testing, and the impact of this guideline for clinicians and patients living with advanced NSCLC. Stay tuned for future updates to this continuously updated guideline. Read the full update, “Therapy for Stage IV Non-Small-Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2023.3” 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.23.02744.    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 am interviewing Dr. Jyoti Patel and Dr. Natasha Leighl, co-chairs on “Therapy for Stage IV Non-Small-Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2023.3.” Thank you for being here, Dr. Patel and Dr. Leighl.  And before we discuss this guideline, I would 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 and Dr. Leighl, who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So, to start us off on this living clinical practice guideline, Dr. Leighl, this guideline for systemic therapy for patients with stage four non-small cell lung cancer with driver alterations is being routinely updated. What new data was reviewed in this full update to the living guideline? Dr. Natasha Leighl: Thanks so much, Brittany. So, we looked through the literature for publications between February and the end of October 2023, and also any novel agents that were approved, in particular by the United States FDA, to really incorporate this update in the current guidelines. In particular, we had updates in EGFR-driven tumors, BRAF and RET-driven tumors. And we also worked very hard to make this more digestible. In particular, it was turning into a bit of a laundry list of all of the things that we had ever recommended. So we really wanted to shorten things, pare them down, and really make them helpful and very, very current for the treatment of people with lung cancer in 2023 and 2024. Brittany Harvey: Excellent. Thank you for providing that overview of the evidence reviewed and the key updates that we will address in this guideline. So then I would like to talk about some of those key updated recommendations from the expert panel. You mentioned both EGFR, BRAF, and RET. So starting with patients with stage IV non-small cell lung cancer with EGFR alterations, Dr. Leighl, what are the key changes to those recommendations? Dr. Natasha Leighl: So, as I said, we really started to get quite a long list of things we recommended, including drugs that, to be honest, we no longer think are what we should lead with first-line. So we updated the recommendation to recommend first-line osimertinib in patients with sensitizing mutations. We were also able to capture in this update for patients with EGFR exon 20 insertion mutant lung cancer, the data from the randomized PAPILLON trial, recommending amivantamab plus chemotherapy for progression-free survival benefit. Not yet an overall survival benefit, but we will see how these data mature.  The other thing that we did was we moved all of the- I don't want to call them "legacy agents" because, in many countries, these are still very important. But older agents such as gefitinib, approaches such as gefitinib plus chemotherapy, and drugs like dacomitinib and other agents where we truly believe as an international panel that we would prefer a third-generation kinase inhibitor like osimertinib. We moved all of those to our discussion, just to recognize that, around the world, not everybody may have access. And we also specified that things are different in different countries. So, for example, in China, there are other third-generation kinase inhibitors with randomized data to support their use. And those are approved and used in China. And also, for example, in Korea, there are other agents that are used. So, we have really tried to be both inclusive and yet keep things simple at the same time. And hopefully, we have succeeded.  One of the challenges was that, with all of the updates that we made, we did not have all of the publications out yet at the end of October to make recommendations about moving beyond osimertinib in the first-line setting. So, please stay tuned for the next guideline update, where we're going to tackle whether we should give osimertinib alone or combination therapy. Brittany Harvey: Excellent. Thank you for providing those updates and clarifications for those patients with non-small cell lung cancer and an EGFR alteration. And we will look forward to the guideline panel's review of that evidence and future updates as well. So then, Dr. Leighl, you had previously mentioned that additional recommendations were updated, such as those for patients with BRAF alterations and RET alterations. So, Dr. Patel, what are the other key updated recommendations from the expert panel? Dr. Jyoti Patel: Thanks so much, Brittany. So certainly, I think we have seen many of these trials mature over time, which has been fantastic. I think one remarkable achievement was the reporting of a phase III selpercatinib trial. This was a trial in the front-line setting, in which patients who were RET-positive were randomized to selpercatinib versus carboplatin-based chemotherapy. And the selpercatinib significantly outperformed platinum-based chemotherapy, and I think really demonstrated a significant improvement in progression-free survival. So, based on that phase III trial, the recommendation for selpercatinib was elevated. Many of these agents that are used in clinical practice are approved initially on smaller phase I or phase II trials. And so, seeing the maturity of these phase III trials gives clinicians and patients greater certainty that these agents are really effective. And so, the evidence was increased for that, and that's now a preferred agent over another TKI, pralsetinib, in which there is only phase II data. So, certainly, those kinds of real things that we can explain to patients are important in these guidelines.  Another thing that we were able to update was another doublet for BRAF V600E non-small cell lung cancer. So, the combination of the two TKIs, encorafenib and binimetinib, was also included in the guidelines.  One thing that we tried to help was really identifying the best therapy post-progression on these first-generation TKIs. And again, there is a paucity of data, but often we went back to carboplatin-based doublets, and there is some data regarding whether or not patients with driver alterations should get immunotherapy in the second-line setting. And so, certainly, I think we have a number of randomized studies for patients with classical EGFR mutations, and our recommendation is generally avoidance of immunotherapy for these patients and treating many of these patients with carboplatin and pemetrexed when appropriate. I do not think we have the data for a lot of other subsets of patients. So, again, stay tuned as these data evolve. Brittany Harvey: Thank you for reviewing those updated recommendations and the supporting evidence. I think it's helpful for our listeners to understand the level of evidence behind these recommendations as well.  So then, Dr. Leighl, what should clinicians know as they implement these new and updated recommendations? Dr. Natasha Leighl: It's really important, first of all, to make sure that you have the information that you need to get your patients to these great new treatments as part of the shared decision-making process. So your patients need biomarker testing. You need to get that as quickly as you can. As Dr. Patel has highlighted, you really want to get that before they start their first-line therapy, if at all possible. We also really tried to bring out in this guideline that when things are delayed, I mean, this is the real world that we live in, just to be very cautious of immunotherapy with chemotherapy for that first cycle. That obviously, again, is a discussion with your patient, but this concept that the approach of a cycle of chemotherapy while you wait for the next-generation sequencing testing. And then if the patient does not have a driver alteration, adding any other therapy as appropriate is okay. It's something that people do. We believe it's important as we talk about the balance between benefits and harms. And so I think that's in there for clinicians, and I hope that they and patients can really benefit from that to avoid toxicity and also to really improve the ability to get molecular testing results first line.  Also, I think it's really important that when people read the wording of the guidelines, that this really follows GRADE, which is a type of system that we use to develop our recommendations. And so things like "may" do not mean that you shouldn't do it. So sometimes we'll hear back from clinicians and say, "Well, you said that they may use alectinib or lorlatinib, for example, with ALK, and I can only get coverage for one or the other." And so I think it's really important that clinicians and patients recognize that all of the things that we do recommend, even if we do use the word "may" or the recommendation is more conditional, we do think that these agents should be available for patients and clinicians, and that they go through this shared decision-making process together.  And so I think that's something that clinicians, we hope, can help take forward as they advocate for their patients to get access to these different and new and emerging treatments that have clearly shown benefit. Even when we say patients and clinicians may use this or that, there may be excellent reasons for using something newer, that's emerged, perhaps for toxicity benefits or benefits in terms of efficacy, even though we can't compare directly. And so we really want clinicians and patients to be empowered to access these new compounds and these new exciting agents that are in our guidelines. Brittany Harvey: Absolutely. Thank you for reviewing those key points. And, yes, that's a great comment that the level of obligation in the recommendations may be based on the evidence quality, but that doesn't mean that clinicians and patients shouldn't have access to all of the recommended treatment options to offer patients based off their individual patient and clinical characteristics.  So then, Dr. Patel, in your view, how will these changes affect patients with non-small cell lung cancer, with driver alterations?  Dr. Jyoti Patel: A lot of this echoes the points made by Dr. Leighl. I think there are opportunities for patients to assess toxicity or what it means for intensification of therapy. So, particularly for EGFR patients, for example, we have data that chemotherapy with osimertinib can improve progression-free survival, or the incorporation of a bispecific antibody, amivantamab, can improve progression-free survival over the TKI alone. It certainly comes with increased toxicity. And so how we weigh this in the absence of a known survival benefit at this juncture is one that, again, really gives patients the opportunity to prioritize what's important for them. And so I think this guideline affects patients and that we have multiple options, we help with the weight of the evidence so they may be able to better discern what treatment makes sense for them. Brittany Harvey: Understood. Yes, this guideline provides lots of options for different patients based off their driver alterations. So it's helpful to have that information for shared decision-making with their clinicians.  So then finally, to wrap us up, Dr. Leighl, what current research is the living guideline expert panel monitoring for updates to the guideline recommendations? Dr. Natasha Leighl: This process of the living guidelines has really been to help us stay on top of the amazing and incredibly rapid progress that we're making in lung cancer and other cancers. And even with this process, where we're trying to stay up-to-the-minute, there have already been some changes in the literature between the start of November and now. And so we're already working on some additional commentary and options for the first-line treatment of patients with EGFR-mutant lung cancer. Also, the subsequent treatment of patients with EGFR-mutant lung cancer, depending on what they've had before. Also, a great new study in patients with ROS1 fusion-driven lung cancer. And so these are some of the things that we're looking at.   Also, a bit more discussion about the importance of molecular testing. In our companion article, the Journal of Oncology Practice, along with Dr. Patel, we're going to be talking a bit more about new ways to genotype, for example, using both liquid biopsy and tumor tissue at the same time, and some of the support for that and how it gets us with our patients to the answers that they need faster.  Brittany Harvey: Absolutely. The pace of research in non-small cell lung cancer has moved quite quickly. So we definitely appreciate the panel's efforts to review all of this evidence on a continuous basis and take the time to develop these guideline recommendations for both clinicians and patients with non-small cell lung cancer.  So I want to thank you so much for your work to update these guidelines, and thank you for your time today, Dr. Patel and Dr. Leighl. Dr. Natasha Leighl: Thanks so much. It's a real pleasure to be here. Dr. Jyoti Patel: Thank you.  Brittany Harvey: And thank you to all of our listeners for tuning in to the ASCO Guidelines podcast.

Lung cancer is a significant global health issue, being the second most commonly diagnosed cancer and the leading cause of cancer-related death worldwide. Non-small-cell lung cancer (NSCLC) represents the majority of lung cancer cases and is often diagnosed at an advanced stage. Epidermal growth factor receptor (EGFR) mutations are more common in Asian NSCLC populations than in Western populations. Activating EGFR mutations, such as exon 19 deletions and L858R, are predictive of response to tyrosine kinase inhibitors (TKIs) and have revolutionized the treatment landscape for patients with EGFR-mutated NSCLC. However, most clinical trials tend to lack data for the elderly population, even though a significant proportion of lung cancer patients are aged 65 years and older. This underrepresentation of elderly patients in clinical trials limits our understanding of the effectiveness and safety of EGFR-TKIs in this specific population. In this new study, researchers Ling-Jen Hung, Ping-Chih Hsu, Cheng-Ta Yang, Chih-Hsi Scott Kuo, John Wen-Cheng Chang, Chen-Yang Huang, Ching-Fu Chang, and Chiao-En Wu from Chang Gung University and Taoyuan General Hospital conducted a multi-institute retrospective study to investigate the effectiveness and safety of afatinib, gefitinib, and erlotinib for treatment-naïve elderly patients with EGFR-mutated advanced NSCLC. On January 8, 2024, their research paper was published in Aging's Volume 16, Issue 1, entitled, “Effectiveness and safety of afatinib, gefitinib, and erlotinib for treatment-naïve elderly patients with epidermal growth factor receptor-mutated advanced non-small-cell lung cancer: a multi-institute retrospective study.” Full blog - https://aging-us.org/2024/01/efficacy-and-safety-of-egfr-tkis-for-elderly-patients-with-nsclc/ Paper DOI - https://doi.org/10.18632/aging.205395 Corresponding author - Chiao-En Wu - 8805017@cgmh.org.tw Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.205395 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, elderly patients, epidermal growth factor receptor, tyrosine kinase inhibitor, non-small-cell lung cancer, real-world evidence About Aging-US Launched in 2009, Aging-US publishes papers of general interest and biological significance in all fields of aging research and age-related diseases, including cancer—and now, with a special focus on COVID-19 vulnerability as an age-dependent syndrome.

Dr Jabbour discusses the activity and the utilization of olverembatinib in chronic myeloid leukemia and expanded upon the role that TKIs can play in the management of malignancies beyond chronic myeloid leukemia and acute lymphoblastic leukemia.

Dr. Cortes, who serves as Director of the Georgia Cancer Center at Augusta University, joins host Chadi Nabhan, MD, MBA, FACP, to chat about the “boom” in treatments for chronic myeloid leukemia (CML), and where he sees a need for balance. Dr. Cortes discussed the evolution of tyrosine kinase inhibitors (TKIs) and the multiple generations of TKIs that are now available. Second-generation TKIs can lead to earlier and deeper responses than first-generation TKIs, he said, noting that this means patients receiving second-generation TKIs are more likely to be able to discontinue treatment. “If I was diagnosed with CML, I would take a second-generation TKI,” Dr. Cortes said. However, Dr. Cortes emphasized that the first-generation TKI imatinib comes with a lower risk of serious side effects than second-generation TKIs. This is an important consideration because “most people are going to do well and have a normal life expectancy” on imatinib, he said. It is critical to evaluate multiple factors when choosing between a first-generation TKI and a second-generation TKI. This means involving patients in the decisions about treatment to ensure they are comfortable with the balance of efficacy and safety, he said. “I certainly would rather have more bags under my eyes than a heart attack,” Dr. Cortes said. “So, we need to balance that, and I think that sometimes we've been a little too obsessed on [obtaining] the lowest possible [polymerase chain reaction] value, and we lose the context of other elements that are important, such as risks, and comorbidities and side effects.” He also discussed a population of patients who remain challenging to treat despite the evolution of therapies for CML. “The most difficult patient is one without a mutation,” Dr. Cortes said, noting this is because response rates are lowest for those without a mutation and “you don't know why they are not responding.”

BUFFALO, NY- September 20, 2023 – A new editorial paper was published in Oncotarget's Volume 14 on September 15, 2023, entitled, “Potential repurposing of DPP4 inhibitors for target therapy resistance in renal cell carcinoma.” In their new editorial, researchers Kuniko Horie and Satoshi Inoue from Saitama Medical University and Tokyo Metropolitan Institute for Geriatrics and Gerontology discuss renal cell carcinoma (RCC) — a major adult kidney cancer, which is often incidentally discovered as an asymptomatic disease on imaging in the developed countries. RCC has the most fatal disease among urological cancers, as a recent 5-year relative survival rate in the U.S. (2009–2015) is less than 80%. While RCC is known as a cancer resistant to chemo- and radio-therapies, the prognosis of RCC has been remarkably improved after the clinical application of tyrosine kinase inhibitors (TKIs) and immunotherapy. The rationale for the efficacy of TKIs in RCC is mainly based on the angiogenetic status, particularly in clear cell RCC (ccRCC) that is the most common type of RCC (70–75% of RCC), in which the loss of function mutation of Von Hippel-Lindau (VHL) tumor suppressor gene activates hypoxia inducible factor (HIF) and vascular endothelial growth factor (VEGF) pathways. The first-line TKIs that predominantly target VEGF receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR) (e.g., sunitinib and sorafenib) have been clinically used since late 2000s, and the second-line TKIs such as cabozantinib, which targets more receptor tyrosine kinases including MET and TAM kinases as well as VEGFR, have been further applied to the treatment of advanced RCC since early 2010s in which the first-line TKIs are ineffective. “In our recent study, we established a panel of patient-derived ccRCC spheroid cultures with the enhancement of cancer stemness gene signature including DPP4 [9]. Focusing on TKI sunitinib sensitivity, we demonstrated that DPP4 inhibition increased sunitinib efficacy in DPP4-high RCC spheroids and DPP4 was upregulated in sunitinib-resistant RCC cells.” DOI - https://doi.org/10.18632/oncotarget.28463 Correspondence to - Satoshi Inoue - sinoue07@gmail.com Sign up for free Altmetric alerts about this article - https://oncotarget.altmetric.com/details/email_updates?id=10.18632%2Foncotarget.28463 Subscribe for free publication alerts from Oncotarget - https://www.oncotarget.com/subscribe/ Keywords - cancer, renal cell carcinoma (RCC), tyrosine kinase inhibitor (TKI), Dipeptidyl peptidase IV (DPP4), drug resistance, drug repurposing About Oncotarget Oncotarget (a primarily oncology-focused, peer-reviewed, open access journal) aims to maximize research impact through insightful peer-review; eliminate borders between specialties by linking different fields of oncology, cancer research and biomedical sciences; and foster application of basic and clinical science.

A new editorial paper was published in Oncotarget's Volume 14 on May 26, 2023, entitled, “Latest updates on MET targeted therapy for EXON 14 mutations in lung cancer.” In their new editorial, researchers Mira Al Jaberi, Wolfgang Clough and Samir Dalia from Mercy Hospital discuss the MET gene. Several alterations in the MET gene were identified as targetable oncogenic changes leading to non-small cell lung cancer (NSCLC). These include genomic amplifications, exon 14 skipping mutations and fusion. Capmatinib has been considered as a first-line treatment for patients with NSCLC carrying a MET exon 14 skipping mutation since May 2020 by the USFDA. A study newly published in early 2023 showed that Crizotinib, a tyrosine kinase inhibitor, was also effective for MET fusions, which occur rarely in 0.2–0.3% of patients with lung cancer. A major challenge arising after the introduction of tyrosine kinase inhibitors is limited clinical benefit, which is due to primary and potential secondary acquired drug resistance. “A major challenge arising after the introduction of tyrosine kinase inhibitors is limited clinical benefit, which is due to primary and potential secondary acquired drug resistance [4, 5].” Several structurally different MET tyrosine kinase inhibitors (TKIs) have been developed or are under clinical evaluation. TKIs are categorized into type I TKIs (type Ia: crizotinib; type Ib: savolitinib, capmatinib) and type II TKIs (cabozantinib, glesatinib, merestinib). Combination therapy reduces resistance and enhances clinical outcomes. “These clinical trials along with others will show us if other MET inhibitors or combination therapy may be better than the current standard of care.” DOI - https://doi.org/10.18632/oncotarget.28419 Correspondence to - Samir Dalia - samir.dalia@mercy.net Sign up for free Altmetric alerts about this article - https://oncotarget.altmetric.com/details/email_updates?id=10.18632%2Foncotarget.28419 Subscribe for free publication alerts from Oncotarget - https://www.oncotarget.com/subscribe/ Keywords - cancer, non small cell lung cancer, MET mutation, targeted therapy, precision medicine About Oncotarget Oncotarget (a primarily oncology-focused, peer-reviewed, open access journal) aims to maximize research impact through insightful peer-review; eliminate borders between specialties by linking different fields of oncology, cancer research and biomedical sciences; and foster application of basic and clinical science.

John Hallick, founder and president of MET Crusaders and co-president of Biomarker Collaborative, joins the podcast to share the story of his journey into patient advocacy. In February 2018, John was diagnosed with stage IV non-small cell lung cancer. Several weeks later, the genetic tests came back, and the cancer was determined to be driven by the MET 14 skipping alteration. After learning from doctors that while there are many support groups for genetic alterations, there was none for his, John took action. He drew from his background as a serial entrepreneur to set up a patient-centric advocacy group for people with his particular genetic alteration. You'll hear about:John's story from his diagnosis of stage IV metastatic cancer to his treatment to where he is todayMET Crusaders, the advocacy group John founded that's dedicated to helping patients with the MET alteration live normal lives Biomarker Collaborative, a comprehensive body that represents all the advocacy groups, and their work connecting patients with the resources and support they need during what is likely the most traumatic point in their life       How others can find support and resourcesMost importantly, you'll meet a courageous individual who is using his own serious life challenge as a springboard to help, educate, and support others.https://biomarkercollaborative.org/John Hallick is a serial entrepreneur of several companies, all based around data warehousing, data mining, and individualized communications management. In December 2017, John developed what he thought might be the flu. It was diagnosed as an upper respiratory infection, and he was prescribed an antibiotic. After several weeks, the symptoms didn't go away, and he went back to the doctor's office. The second diagnosis was bronchitis, and he was prescribed prednisone. Again, the illness never went away. In January of 2018, he flew a helicopter four hours from Madison, WI, to Louisville, KY. The drive back to Madison was eight hours. He coughed on and off the entire drive back home. The next day, he went back to the doctor, and they decided to take an X-ray. The X-ray showed he had a mass in his right lung. As a note, nine months earlier he had a normal chest X-ray. At the end of January 2018, the Mayo Clinic in Rochester, MN, performed a complete workup, including PET scans, CT scans, brain MRIs, bone scans, and blood work. On February 1, 2018, at age 67, John was diagnosed with stage IV non-small cell lung cancer. Several weeks later, the genetic tests came back, and the cancer was determined to be driven by the MET 14 skipping alteration. His initial treatment was a combination of carboplatin, Alimta, and Keytruda every three weeks. John experienced all the normal side effects, including losing 65 pounds and half his hair, hearing loss, neuropathy on the bottom of his feet, no energy, and a significant loss of red blood cells. He was given two units of blood to get his red blood cells back into range. After four treatment sessions, carboplatin was removed from his treatment due to intolerability. After a total of five months of mixed results, it was decided for him to have one additional treatment and look for a clinical trial. After the last treatment, the immunotherapy started to work, and the tumors shrunk about one-third.   Now John had to make the decision of whether to stay on the current treatment plan or go on the trial. John decided to go on the capmatinib phase 2 clinical trial in July 2018. At first, the tumors shrank and then became stable. Targeted therapy returned his quality of life. Like all TKIs, capmatinib stayed effective for over three-and-a-half years. John trialed a MET antibody with limited success and is back on chemo and immune therapy.
