You can find all the shows, including this one, at asco.org/podcasts.   My name is Brittany Harvey, and today I am interviewing Dr. Lakshmi Rajdev from the Icahn School of Medicine at Mount Sinai and Dr. Manish Shah from Weill Cornell Medicine, co-chairs on "Immunotherapy and Targeted Therapy for Advanced Gastroesophageal Cancer: ASCO Guideline Update." Thank you for being here today, Dr. Rajdev and Dr. Shah. Dr. Lakshmi Rajdev: Thank you. Dr. Manish Shah: Thank you for having us. It is wonderful. Brittany Harvey: And then just 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. Rajdev and Dr. Shah, 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 then to dive into what we are here today to talk about, Dr. Shah, I would like to start first with what prompted the update to this guideline, which was previously published in 2023, and what is the scope of this updated guideline? Dr. Manish Shah: Yes, terrific. So even in the last few years, the pace of drug development in gastroesophageal cancers has just been astounding. So, what prompted this guideline is actually the practice-changing results for a new biomarker, CLDN18.2 hat was based on the GLOW and SPOTLIGHT studies, as well as a practice-changing study in HER2-positive disease where we added pembrolizumab to trastuzumab and chemotherapy for tumors that are HER2-positive and PD-L1 CPS 1 or greater. And then there were also new studies and new approvals in esophageal squamous cell cancer that you will hear about as well. So there were several studies, overall more than 5,000 patients were reported on, and that led to several new therapies, new indications, and it really necessitated this guideline. Brittany Harvey: Excellent. It is great to hear about all of these exciting updates in this space. So then to next review the key recommendations of this guideline by clinical question that the expert panel addressed. So, Dr. Rajdev, what is the recommended first-line treatment for patients with proficient mismatch repair, microsatellite stable, HER2-negative gastroesophageal adenocarcinoma? Dr. Lakshmi Rajdev: Thank you for that question. So historically, we have sort of used fluoropyrimidine and platinum doublets, which yielded a survival of about one year. More recently, immunotherapy and targeted therapy options have improved outcomes in patients with advanced esophageal and gastric adenocarcinoma, as well as squamous cell carcinoma. Patients with gastric and GE junction adenocarcinoma have a high rate of actionable alterations, so it is imperative that physicians test the following biomarkers upfront so that it can help guide therapy. The markers recommended by the ASCO panel are HER2, MMR or MSI, CLDN18.2, and PD-L1. And also, it was recommended to use NGS if feasible in this patient population. HER2, as we know, is expressed in about 15% to 25% of patients; PD-L1 expression occurs in about 80% of patients; MSI-high, deficient MMR is present in about 5% to 8% of patients; and CLDN18.2 expression is present in about 40% of patients. There is, of course, biomarker overlap. About 13% to 22% of CLDN18.2 patients are also PD-L1 positive. For patients with pMMR or microsatellite stable HER2-negative disease with PD-L1 expression greater than 1 and absence of CLDN18.2, the panel recommended a first-line therapy with fluoropyrimidine and platinum-based therapy in combination with immunotherapy. These recommendations stem from large phase 3 trials, and the agents approved in the United States are pembrolizumab, nivolumab, and tislelizumab. It has been shown that immunotherapy benefit is greater in patients with higher PD-L1 expression, and it is not possible to comment on the individual PD-L1 cutoff scores and sort of identify the optimal PD-L1 cutoff score that sort of balances benefits and harms. But what is recommended is that immunotherapy-based treatments can be offered in patients with a CPS score of greater than 1. With regard to the choice of immunotherapy agents, that is pembrolizumab, nivolumab, or tislelizumab, these agents are considered to have similar efficacy, and the selection of an agent could be based on dosing schedule, cost considerations, toxicity, and the method of administration. Typically, clinicians should avoid withholding the start of chemotherapy while awaiting biomarker testing, depending on the clinical scenario. Now, for patients with pMMR microsatellite stable disease that is HER2-negative with PD-L1 expression less than 1 and positive CLDN18.2 expression, zolbetuximab-based treatments or in combination with chemotherapy is recommended, and this is based on two global phase III randomized controlled trials, the GLOW and the SPOTLIGHT. And across both studies, the hazard ratio for the overall survival was 0.78, and similarly, there was also an improvement in progression-free survival favoring the zolbetuximab group compared to the chemotherapy group alone. An important note is that nausea, vomiting is commonly associated with zolbetuximab-based treatments, and the panel recommended prophylactic antiemetics, adjusting zolbetuximab infusion rates, pausing infusion temporarily, using non-prophylactic antiemetics, and hydration intravenously prior to discontinuation of zolbetuximab-based chemotherapy. So effective handling of the GI-related symptoms with zolbetuximab is recommended prior to discontinuation of therapy. Now, for patients with pMMR microsatellite stable HER2-negative gastric, GE junction adenocarcinoma with PD-L1 expression greater than 1 and CLDN18.2 positivity, the ones with the dual expression with CLDN18.2 as well as PD-L1 chemotherapy, the choice of therapy can be based on the degree of PD-L1 expression, the toxicity profile, the burden of symptoms, and the anticipated improvement in symptoms associated with response to treatment, the patient comorbidities, the prior medical and treatment history. So this decision needs to be made on a case-by-case basis, and these are some of the factors that we suggested that could potentially influence the choice of therapy. For patients with pMMR microsatellite stable disease that is HER2-negative and a PD-L1 expression less than 1 and an absence of CLDN18.2 expression, first-line therapy with fluoropyrimidine and platinum-based chemotherapy is recommended. So you can see we have segmented out patients based on PD-L1 expression, pMMR and microsatellite stable disease expression, and also based on CLDN expression. Brittany Harvey: Absolutely. And that first point you noted, I think is really important, that biomarker testing is really critical for treatment decision-making in this space. So then the next subgroup of patients that the panel looked at, Dr. Shah, what first-line therapy is recommended for patients with proficient mismatch repair, microsatellite stable, HER2-positive gastroesophageal adenocarcinoma? Dr. Manish Shah: So this was an update from a few years ago. So we have known for 15 years now that if you are HER2-positive, you should get trastuzumab plus chemotherapy. That was based on the ToGA trial. And the update now is based on a trial called KEYNOTE-811, where it examined the addition of pembrolizumab to trastuzumab and chemotherapy versus trastuzumab and chemotherapy, and there was a progression-free and overall survival benefit. And again, here, the biomarkers are important. If your CPS PD-L1 is less than 1, we would not recommend Pembrolizumab in that setting, so you would still get trastuzumab and chemotherapy. But if it is 1 or greater, the PD-L1 CPS score, then we do recommend pembrolizumab unless there is a contraindication to immunotherapy. The take-home message really is from the onset of diagnosis, please check your biomarkers. And I will just, it is worth repeating, it is important to check your PD-L1 status, HER2 status, mismatch repair status, and CLDN18.2 status. And then the optimal therapy, and it is outlined in the publication, is really biomarker-driven. We know that if we are able to hit the target that is overexpressed, we are going to have a better outcome. And Dr. Rajdev did mention where there is overlap, there can be a lack of data, and that is where we are with both PD-L1 positive and CLDN positive. Here we do have data in HER2-positive cases where if you are both HER2-positive and PD-L1 positive, you would combine trastuzumab and pembrolizumab for the best outcomes. Brittany Harvey: Understood. I really appreciate you detailing what is most important for each individual biomarker combination that patients may have. So then following that, Dr. Rajdev, what does the expert panel recommend for first-line treatment for patients with esophageal squamous cell carcinoma that is not amenable to definitive chemoradiation? Dr. Lakshmi Rajdev: There are three phase III randomized clinical trials that have influenced practice in patients with esophageal squamous cell carcinoma examining the benefit of immunotherapy in this patient population. The RATIONALE-306 was a randomized trial of tislelizumab plus chemotherapy with platinum and fluoropyrimidine or paclitaxel versus placebo with chemotherapy. And then you have the KEYNOTE-590, which compared pembrolizumab plus chemotherapy versus chemotherapy alone. And then you have CheckMate-648, which included comparisons of nivolumab plus chemotherapy versus nivolumab plus ipilimumab or chemotherapy. And the primary endpoints for these studies were overall survival, and they did look at subgroups with PD-L1 expression. They used TPS score greater than 1% in CheckMate-648 and PD-L1 CPS greater than 10 in KEYNOTE-590. The bottom line is that the overall hazard ratio for overall survival across this patient population was 0.72. So clearly, there is benefit in patients that express PD-L1 CPS greater than 1 for benefit for the addition of immunotherapy. Now, the benefit again in patients with a PD-L1 expression less than 1 remains limited, and so the panel has made a recommendation for using immunotherapy in combination with platinum-based chemotherapy in patients with a PD-L1 greater than 1. Again, we know that it is hard to make recommendations on what PD-L1 cutoffs are recommended in this patient population, meaning that should it be limited to patients with a PD-L1 of 1 to 4 or greater than 10? I think that the general consensus that has been gleaned from the data is that the higher the PD-L1 expression, the greater the benefit. I do want to comment on another option that is available in patients with squamous cell carcinoma compared to adenocarcinoma, and that is the combination of nivolumab and ipilimumab. Now, in CheckMate-648, nivolumab with ipilimumab was also recommended as a treatment option in patients that have a PD-L1 score of greater than 1. There was a survival benefit demonstrated with this combination compared to chemotherapy alone. And an important observation in this study is that, although there was a slightly increased rate in early death, but there was really no significant difference in PFS and OS compared to chemotherapy alone. Importantly, the treatment appeared to be pretty well tolerated by the study population. There was a notable difference in the objective response rate, which was 35% in the nivolumab plus ipilimumab group compared to patients receiving nivolumab and chemotherapy, where it was 53%. So superiority is, so the importance of chemotherapy in patients with esophageal squamous cell carcinoma is to be noted. However, there is no difference in overall survival and progression-free survival when using the combination of nivolumab and ipilimumab, and thus it affords a chemotherapy-free option for this patient population with esophageal squamous cell carcinoma and a CPS with a score of greater than 1. Brittany Harvey: Understood. I appreciate you reviewing the evidence underpinning those recommendations as well. So then the next patient population that the guideline panel addressed, what first-line therapy is recommended for patients with deficient mismatch repair, microsatellite instability-high, gastroesophageal adenocarcinoma or esophageal squamous cell carcinoma? Dr. Lakshmi Rajdev: The rate of MSI-high expression is about 3% to 7% across different studies. Now, the KEYNOTE-158 was a tumor-agnostic study in patients with non-colorectal cancers, and again, the problem with the MSI-high population, given that it is so rare, the numbers in the individual studies are fairly small. But consistent outcomes do emerge, indicating high response to immunotherapy. So in KEYNOTE-158, a response rate of about 46% was noted. The number of patients was small, it was about 24. In CheckMate-649, which is a study of chemotherapy plus or minus nivolumab in patients with advanced gastric adenocarcinoma, there was again a very small number of patients, and patients that were MSI-high or deficient MMR did experience substantial benefits with the addition of immunotherapy, with hazard ratios in the order of about 0.38. In KEYNOTE-062, again, it was a very small number of patients, again about 6% or so, and similar to CheckMate-649, a substantial benefit was noted in combination with chemotherapy, but also there were benefits noted with pembrolizumab alone. The RATIONALE-305 again was a study of tislelizumab in combination with chemotherapy and similarly showed benefits to the combination of chemotherapy plus immunotherapy in this patient population. I think that we are all aware of the dramatic benefits of immunotherapy in this particular subset of patients, deficient MMR MSI-high, and also we have seen in CheckMate-649 they did have a subset of patients that received nivolumab and ipilimumab. And in this patient population, they noted unstratified hazard ratio of 0.28. So I think that the overall consensus is that immunotherapy is a very important treatment modality in patients with deficient MMR MSI-high disease, given that a lot of the trials in gastroesophageal adenocarcinoma have utilized chemotherapy-based options, that is certainly a recommendation of the panel to use chemotherapy in combination with immunotherapy. However, on a case-by-case basis, the panel recommended immunotherapy alone as well, and given the high response rates noted in trials across different diseases as well as noted in this disease as well. Brittany Harvey: Certainly. And I appreciate you both for reviewing these first-line recommendations. So moving to later lines of therapy, Dr. Rajdev, what recommendations did the expert panel make for second or third-line therapy for gastroesophageal adenocarcinoma and esophageal squamous cell carcinoma? Dr. Lakshmi Rajdev: So, I think that the RAINBOW trial that investigated the utility of the addition of ramucirumab as second-line therapy has been around since 2014, and those results have led to the addition of ramucirumab to taxane-based therapy in the second-line setting. Based on the utilization of oxaliplatin and platinum-based therapy in the front-line setting, there may be patients that have an underlying neuropathy, and so we wanted to really include treatment options for this patient population so that an agent that is less neurotoxic could also be recommended in combination with ramucirumab. The RAMIRIS trial is one such trial where ramucirumab was combined with FOLFIRI, and it demonstrated benefit in combination with ramucirumab. So we have listed that as a potential treatment option for patients in the second-line setting who may have an underlying neuropathy or even for whatever reason that based on the toxicity profile, that needs to be the preferred option by a physician, that recommendation is new from the older guidelines that we have. With regard to the utility of PD-1 inhibitors, there really has been no benefit noted in the second-line setting with regard to overall survival or progression-free survival, so no recommendation is made for that option. I think an important study that has been recently presented is the DESTINY-Gastric04 trial, which really has been practice-changing and has led to the recommendation for trastuzumab deruxtecan in patients that have HER2-positive metastatic gastric or GE junction adenocarcinoma. Now, this is a phase III trial in patients who retained HER2-positive disease after progressing on front-line trastuzumab-based treatments, and the comparator for this trial was trastuzumab deruxtecan versus ramucirumab plus paclitaxel. There was significant improvement and progression-free survival in patients that received trastuzumab deruxtecan. The patients that were excluded from the trial are patients that have pulmonary problems, interstitial lung disease; that is one of the toxicities of this particular agent, and close monitoring and prompt initiation of therapy such as glucocorticoid treatment in patients who develop this toxicity was also highlighted by the panel. So to summarize, the new guidelines highlight the possibility of FOLFIRI plus ramucirumab as a second-line option and then trastuzumab deruxtecan as a later-line option in patients that still retain HER2 expression. And that is very important because the trial did retest patients whether they expressed HER2. As we know, in a substantial number of patients, there is downregulation of HER2, and there is emerging data that the benefit for subsequent HER2-directed therapies is best noted in patients that still retain HER2 expression. Brittany Harvey: Great. So as our listeners have heard, there are many recommendations and new treatment options for advanced gastroesophageal cancer. Dr. Shah, earlier you highlighted the importance of biomarker testing, but I would like to hear in your view, what is the importance of this guideline and how will it impact both clinicians and patients with gastroesophageal carcinoma? Dr. Manish Shah: So as we have discussed throughout this podcast, the treatment for gastroesophageal cancer, both adenocarcinoma and squamous cell cancer, is increasingly complex, increasingly biomarker-driven. And I think the value of the guideline is to place all of that into context. So it provides the data for why certain biomarkers are important, what therapies should be indicated. Not only that, but if you are able to review the guideline, it provides the details of each of these studies and summarizes them in a meta-analysis fashion to sort of give you the context, because sometimes the individual studies can be maybe a little bit discordant or confusing and the guideline attempts to harmonize all that. And then also, I think the tables are very, very interesting because they give you actual numbers in terms of how many patients over a thousand would this benefit or how many patients over a thousand would this cause harm in terms of nausea, vomiting, or other things like that. So it gives you context for helping clinicians and patients weigh the potential benefits of the novel treatment strategies against the potential adverse events. And then finally, the guideline does also provide an algorithm that you are able to follow based on the biomarkers, and those are in figures 4 and 5. So I think overall, it is a very comprehensive guideline. It intends to make more manageable a very complex subject, and you know, I really encourage our listeners to review it after listening to the podcast. Dr. Lakshmi Rajdev: If I can add to that, I think that what is also really good about the guidelines is there are quick summaries. So if someone is busy in the clinic, of course, there is the opportunity to review the data supporting the guidelines in great depth in the manuscript, but what is also really good is that there are good summaries. In the event that you are very busy, you can easily identify what the recommendations should be for that particular patient based on these summaries. Brittany Harvey: Absolutely. Listeners are encouraged to review the full guideline, including those tables and figures that may be more helpful when they are looking for something quick to look at in the clinic as well. So, as you both mentioned, there have been a number of recent practice-changing trials in this area. So I imagine there is still a lot of ongoing research as well. So Dr. Shah, what are the outstanding questions regarding treatment options for patients with locally advanced unresectable, advanced, or metastatic gastroesophageal carcinoma? Dr. Manish Shah: I think we touched upon it a little bit. The guidelines are based on the data available, and they are primarily examining one novel therapy with chemotherapy in a specific biomarker population. But as you know, the biomarkers are not either/or; you are not either CLDN18.2 positive or PD-L1 positive. A portion of patients could have dual biomarkers, and you know, I think that we are generating data on how to manage those patients. At the recent GI Symposium in January this year, the ILUSTRO trial was presented by Dr. Shitara, which looked at combining zolbetuximab and chemotherapy with immunotherapy for dual-positive biomarkers, and that is leading to a phase III study that has begun to enroll. So unanswered questions are: how do we manage dual-positive biomarkers? The other thing that was mentioned is that the current data for mismatch repair deficiency involve chemotherapy plus immunotherapy. Only squamous cell cancer is there a study with a positive non-chemotherapy kind of backbone, that is CheckMate-648 that Dr. Rajdev mentioned. As we move forward, it will be good to get data on non-chemotherapy options in certain biomarker-positive populations. And then finally, another update, which is likely to be practice-changing, is the HERIZON-GEA-01 study that looked at zanidatamab, which is another biparatopic antibody that targets HER2, and that is likely to change practice. And as that data gets published, we may look to even do a rapid update for the current immunotherapy and targeted therapy guideline that is just being published. Dr. Lakshmi Rajdev: So, if I can add to that, there are numerous ADCs that look very interesting. There are bispecific antibodies; in fact, the zanidatamab is a bispecific antibody showing improved activity in patients with HER2-positive disease. So I think there are studies from Asia looking at CLDN CAR T-based therapies. So, I think that there are a lot of novel agents and a lot of excitement in the field. We know that the bemarituzumab study, unfortunately, the FGFR2 inhibitor failed to demonstrate any benefit, but I think that there are other agents that are being explored, so there are newer targets, newer agents, ADCs, bispecifics that could potentially change the field in the future. Brittany Harvey: Yes, we will look forward to the data to address these unanswered questions and new agents and inform future guideline updates. So, I would like to thank you both for all of your work to review the evidence here and update this important guideline, and for your time today, Dr. Rajdev and Dr. Shah.

Swedish biotech Affibody has spent over two decades engineering proteins 1/20th the size of a conventional monoclonal antibody — and CEO David Bejker believes they're perfectly suited to solve one of radioligand therapy's biggest problems: a dangerously narrow target space. Bejker discusses how Affibody's platform combines the selectivity of antibodies with the biodistribution flexibility of small molecules, the science behind its Albumod technology, and how its HER2 imaging and therapeutic programs are translating from animals to humans. He also digs into partnerships with AstraZeneca's respiratory unit and complement-focused Rally Bio, manufacturing advantages of E. coli-based production, and Affibody's long-term ambitions as a commercial-stage company.

Sarah Poland, MD, lead author of a recently published article in the journal ONCOLOGY titled Advances in Immunotherapy for Breast Cancer, highlighted key findings from her review in a conversation with CancerNetwork®.1 Throughout the discussion, she spoke about: Shifting Perspectives on Immunogenicity: Historically, breast cancer was considered a “cold,” poorly immunogenic tumor due to low tumor mutational burden (TMB) and few tumor-infiltrating lymphocytes (TILs). Poland highlighted how clinical research has shifted this perspective, particularly through the study of triple-negative breast cancer (TNBC), which often exhibits higher PD-L1 expression and immune infiltration.Key Clinical Milestones: The review highlighted foundational data that established immunotherapy as a standard of care: Early-Stage TNBC: The phase 3 KEYNOTE-522 trial (NCT03036488) established pembrolizumab (Keytruda) plus chemotherapy as a standard neoadjuvant treatment for stage II to III TNBC.2 Metastatic TNBC: The phase 3 KEYNOTE-355 trial (NCT02819518) demonstrated the benefit of pembrolizumab in PD-L1–positive metastatic disease.3 Managing Toxicity and Rechallenge: Poland addressed the feasibility of pembrolizumab rechallenge after an immune-related adverse effect (irAE), emphasizing that while possible, it requires a highly individualized approach based on the severity and timing of the initial toxicity.The Future Landscape: Beyond PD-1/PD-L1 inhibitors, the discussion covered emerging technologies that are poised to redefine treatment: Antibody-Drug Conjugates (ADCs): Exploration of novel combinations of ADCs with immunotherapy. Emerging Modalities: The potential role of bispecific antibodies and vaccine trials utilizing tumor antigens. Subtype Expansion: Emerging evidence supporting the efficacy of immunotherapy in hormone receptor–positive and HER2-positive subtypes, moving beyond the traditional focus on TNBC.

Breast cancer screening is often treated as a given. Mammograms are framed as routine, early detection as unquestionably life-saving, and following guidelines as the responsible choice. But what if the full picture is more complicated?In this episode of hol+, Dr. Taz sits down with integrative oncologist and breast surgeon Dr. Jenn Simmons, author of The Smart Woman's Guide to Breast Cancer, to explore what breast cancer screening data actually shows, where common narratives may oversimplify reality, and how statistics can sometimes be misunderstood by both patients and providers.Together, they discuss the difference between screening and diagnostic imaging, why detecting more cancers does not always mean fewer deaths, and how concepts like overdiagnosis and lead-time bias shape our interpretation of outcomes. Dr. Jenn also explains how breast cancer behaves differently from many other cancers, why progression is not always linear, and what tumor markers like ER, PR, HER2, and triple-negative really indicate.The conversation expands beyond imaging into a whole-body view of breast health, touching on inflammation, immune function, metabolic health, toxic burden, stress, and lifestyle as factors that shape cancer risk and recovery. Rather than promoting fear or urgency, this episode focuses on helping listeners understand their bodies, ask better questions, and make informed decisions with clarity.This episode is for anyone who wants a deeper understanding of breast cancer screening, feels overwhelmed by conflicting guidance, or wants to approach breast health with more nuance and less panic.About Dr. Jenn SimmonsDr. Jenn Simmons is an integrative oncologist, breast surgeon, and founder of Real Health MD. She was Philadelphia's first fellowship-trained breast surgeon and spent nearly two decades leading one of the region's top breast programs before transitioning into integrative oncology.Drawing from her experience in conventional cancer care and her own health journey, Dr. Simmons now focuses on whole-body approaches to breast health, cancer prevention, and recovery, including metabolic health, inflammation, immune function, lifestyle medicine, and root-cause healing. She is the author of The Smart Woman's Guide to Breast Cancer, a patient-centered resource designed to help women better understand their diagnosis, ask informed questions, and navigate treatment decisions with clarity rather than fear.Order the BookThe Smart Woman's Guide to Breast Cancer Stay Connected:Connect further to Hol+ at https://holplus.co/- Don't forget to like, subscribe, and hit the notification bell to stay updated on future episodes of hol+.Follow Dr. Jenn SimmonsInstagram: https://www.instagram.com/drjennsimmonsYouTube: https://www.youtube.com/@dr.jennsimmonsWebsite: https://www.jennsimmonsmd.com/Follow Dr. Taz on Instagram: https://www.instagram.com/drtazmd/https://www.instagram.com/liveholplus/Subscribe to the audio podcast: https://holplus.transistor.fm/subscribeSubscribe to the video podcast: https://www.youtube.com/@DrTazMD/podcastsGet your copy of The Hormone Shift: Balance Your Body and Thrive Through Midlife and MenopauseHost & Production TeamHost: Dr. Taz; Produced by ClipGrowth.com (Producer: Pat Gostek)00:00 Swedish trial claim and overdiagnosis framing 00:52 Why this became a part two conversation 03:25 Reframing screening narratives and medical training gaps 04:39 Why Dr. Simmons questions mammograms as a screening tool 06:06 Origins of screening programs and “invitation to screen” bias 07:12 Relative risk vs absolute numbers example (4 vs 5 per 1,000) 08:49 Overdiagnosis explained with a vivid analogy 09:50 Autopsy-study claim and the “microscopic cancer” idea 12:11 Swedish trial claim revisited: more diagnoses, same deaths 13:38 Downstream harms: callbacks, biopsies, overtreatment 15:04 Lead-time bias and survival statistics explained 16:44 Dr. Simmons' view on the founder's regret narrative 18:16 Switzerland headline clarified and what actually changed 20:10 Cautionary stories and aggressive cancers discussion 22:07 Why breast cancer does not always progress linearly 24:21 Buckets: DCIS, invasive, inflammatory, receptor types 26:15 Clinical vs subclinical disease approach 28:25 Long-term tradeoffs and “forgotten woman” after treatment 32:15 What ER PR HER2 mean biologically and system incentives 35:33 Testosterone discussion and prevention claim presented 42:15 Hormones after breast cancer and the 4-year “reintroduction” idea 44:29 Triple negative: environment, toxicity, immune system focus 49:19 What to do next: pause, exceptions, whole-body workup 52:32 Prevention and breast health approach begins 53:24 At-home tears test explanation (as discussed) 56:24 Detox basics and why sweating is emphasized 59:34 Imaging preferences for screening and what to do if limited access

Drs. Campos and Dizon explore how groundbreaking research is redefining HER2-targeted therapies in gynecological cancers, moving beyond the old one-size-fits-all approach. They spotlight the promise and ongoing challenges of customizing treatment using new biomarkers and clinical trial data.

Twenty years ago, seven people diagnosed with metastatic HER2-positive breast cancer received a cancer vaccine as part of a clinical trial. Today, they're all still alive. This prompted Zachary Hartman to study the immune systems of the people in the trial to see what was happening. He found that the women had immune cells that continue to recognize the cancer and keep it under control. Now his goal is to make that vaccine even more effective and make it work on other types of breast cancer. Listen to the episode to hear Dr. Hartman explain: how the original study was done how he's working to make the vaccine even more effective how the vaccine might be modified to work on hormone receptor-positive and triple-negative breast cancer

Read the full living guideline update "Therapy for Stage IV Non-Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2026.3.0" at www.asco.org/thoracic-cancer-guidelines TRANSCRIPT This guideline, clinical tools and resources are available at www.asco.org/thoracic-cancer-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-25-02822    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. Sonam Puri from Moffitt Cancer Center, co-chair on "Therapy for Stage IV Non-Small Cell Lung Cancer with Driver Alterations: ASCO Living Guideline, Version 2026.3.0." It's great to have you here today, Dr. Puri. Dr. Sonam Puri: Thanks, Brittany. Brittany Harvey: And then just 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. Puri, 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 that we're here today to talk about, Dr. Puri, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer with driver alterations is updated on an ongoing basis. So, what data prompted this latest update to the recommendations? Dr. Sonam Puri: So Brittany, non-small cell lung cancer is one of the fastest-moving areas in oncology right now, particularly when it comes to targeted therapy for driver alterations. New data are emerging continuously from clinical trials, regulatory approvals, real-world experience, which is exactly why these are living guidelines. The goal is to rapidly integrate important advances as they happen, rather than waiting for years for a traditional update. Since the last full update of the ASCO Stage IV Non-small Cell Lung Cancer Guideline with Driver Alterations published in 2024, there have been seven new regulatory approvals and changes in first-line therapy for some driver alterations. [This version] of the "Stage IV Non-small Cell Lung Cancer Guidelines with Driver Alterations" represents a full update, which means that the panel reviewed and refreshed every applicable section of the guideline to reflect the most current evidence across therapies including sequencing and clinical decision-making. This is to ensure that clinicians have up-to-date practical guidelines that keep pace with how quickly the field is evolving. Brittany Harvey: Absolutely. As you mentioned, this is a very fast-moving space and this full update helps condense all of those versions that the panel reviewed before into one document, along with additional approvals and new trials that you reviewed during this time period. So then, the first aspect of the guideline is there's a new overarching recommendation on biomarker testing. Could you speak a little bit to that updated recommendation? Dr. Sonam Puri: Yeah, definitely. So the panel has discussed and provided recommendations on comprehensive biomarker testing and its importance in all patients diagnosed with non-small cell lung cancer. Ideally, biomarker testing should include a broad-based next-generation sequencing panel, rather than single-gene tests, along with immunohistochemistry for important markers such as PD-L1, HER2, and MET. These results really drive treatment decisions, both in frontline settings for all patients diagnosed with non-small cell lung cancer and in subsequent line settings for patients with non-small cell lung cancer harboring certain targetable alterations. Specifically in the frontline setting, it helps determine whether a patient should receive upfront targeted therapy or immunotherapy-based approach. We now have strong data that shows that complete molecular profiling results before starting first-line therapy is associated with better overall survival and actually more cost-effective care. Using both tissue and blood-based testing can improve likelihood of getting actionable results in a timely way, and we've also provided guidance on platforms that include RNA sequencing, which are specifically helpful for identifying gene fusions that might be otherwise missed with other platforms. On the flip side, outside of a truly resource-limited setting, single-gene PCR testing really should not be routine anymore. This is what the panel recommends. It's less sensitive and inefficient and increases the risk of missing important actionable alterations. Brittany Harvey: Understood. I appreciate you reviewing that recommendation. It really helps identify critical individual factors to match the best treatment option to each individual patient. So then, following that recommendation, what are the updated recommendations on first-line therapy for patients with stage IV non-small cell lung cancer with a driver alteration? Dr. Sonam Puri: Since the last full update in 2024, there have been four additional interim updates which were published across 2024 and 2025. Compared to the last version, there have been several updates which have been included in this full update. One of the most important shifts has been in first-line treatment of patients with non-small cell lung cancer harboring the classical, or what we call as typical, EGFR mutation. The current version of the recommendation is based on the updated survival data from the phase III FLAURA2 and MARIPOSA studies, based on which the panel recommended to offer either osimertinib combined with platinum-pemetrexed chemotherapy or the combination of amivantamab plus lazertinib in the first-line treatment of classical EGFR mutations. And these recommendations, as I mentioned, are grounded in the results of the FLAURA2 and MARIPOSA trials, both of which demonstrated improvement in progression-free survival and overall survival compared to osimertinib alone in patients with common EGFR mutations. That being said, the panel actually spent significant time discussing the toxicities associated with these treatments as well. These combination approaches come with higher toxicity, longer infusion time, increased treatment frequency. So while combination therapy is now recommended as preferred, the panel has recommended that osimertinib monotherapy remains a reasonable option, particularly for patients with poor performance status and for those who are not interested in treatment intensification after knowing the risks and benefits. Brittany Harvey: Absolutely. It's important to consider both those benefits and risks of those adverse events that you mentioned to match appropriately individualized patient care. So then, beyond those recommendations for first-line therapy, what is new for second-line and subsequent therapies? Dr. Sonam Puri: So this is a section that saw several major updates, particularly again in the EGFR space. The first was an update on treatment after progression on osimertinib for patients with classical EGFR mutation. Here the panel recommends the combination of amivantamab plus chemotherapy, and this recommendation was based on the phase III MARIPOSA-2 trial, which compared amivantamab plus chemotherapy with chemotherapy alone with progression-free survival as the primary endpoint. The study met its primary endpoint, showing an improvement in median PFS with the combination of amivantamab plus chemotherapy compared to chemotherapy alone. And as expected, the combination was associated with higher toxicity. So, although the panel recommends this regimen, the panel emphasizes that patients should be counseled on the side effects which may be moderate to severe with the combination therapy approach. In addition, a new recommendation was added for patients who are not candidates for amivantamab plus chemotherapy. In those cases, platinum-based chemotherapy with or without continuation of osimertinib may be offered, and the option of continuing osimertinib with chemotherapy was recommended and supported by data from a recently presented phase III COMPEL study, which randomized 98 patients with EGFR exon 19 deletion or L858R-mutated advanced non-small cell lung cancer who had experienced no CNS progression on first-line osimertinib, and these patients were randomized to receive platinum-pemetrexed chemotherapy with osimertinib or placebo. Although this study was small, it demonstrated a PFS benefit with continuation of osimertinib with chemotherapy, and this approach may be appropriate for patients without CNS progression who prefer or require alternatives to more intensive treatment strategies. Next was an update on options for patients with EGFR-mutated lung cancer after progression on osimertinib and platinum-based chemotherapy. Here the panel recommended that for patients whose disease has progressed after both osimertinib and platinum-based chemotherapy, a new drug known as datopotamab deruxtecan can be offered as a treatment option. And this treatment recommendation was based on evaluation of pooled data from the TROPION-Lung01 and TROPION-Lung05 study, in which in the pooled analysis about 114 patients with EGFR-mutant non-small cell lung cancer were treated with Dato-DXd, 57% of whom had received three or more prior lines of treatment, and what was observed was an overall response rate of 45% with a median duration of response of 6.5 months. So definitely promising results. Next, we focused on updates to subsequent therapy options for patients with another type of EGFR mutation known as EGFR exon 20 insertion mutations. In this section, the panel added sunvozertinib as a subsequent line option after progression on platinum-based chemotherapy with or without amivantamab. Sunvozertinib is an oral, irreversible, and selective EGFR tyrosine kinase inhibitor with efficacy demonstrated in the phase II WU-KONG6 study conducted in Chinese patient population. In this study, amongst 104 patients with platinum-pretreated EGFR exon 20 mutated non-small cell lung cancer, the observed response rate was 61%. Staying in the EGFR space, the panel added a recommendation for patients with acquired MET amplification following progression on EGFR TKI therapy. In these situations, the panel recommended that treatment may be offered with osimertinib in combination with either tepotinib or savolitinib. As our listeners may know, MET amplification occurs in approximately 10% to 15% of patients with EGFR-mutated non-small cell lung cancer when they progress on third-generation EGFR TKIs, and detection of MET amplification is done with various methods, such as tissue-based methods like FISH, NGS, and IHC, as well as ctDNA-based NGS with variable cut-offs. Over the last few years, several studies have informed this recommendation. I'm going to be discussing some of them. In the phase II ORCHARD trial, 32 patients with MET-amplified non-small cell lung cancer after progression on first-line osimertinib were evaluated, where the combination of osimertinib plus savolitinib achieved an overall response rate of 47% with a duration of response of 14.5 months. More recently, the phase II SAVANNAH trial reported outcomes in 80 patients with MET-amplified tumors after progression on osimertinib, and in this patient population, the combination of savolitinib and osimertinib achieved an overall response rate of 56% with a median PFS of 7.4 months. And lastly, the phase II single-arm INSIGHT 2 trial assessed the efficacy of osimertinib plus tepotinib in patients with advanced EGFR-mutant non-small cell lung cancer who had disease progression following first-line osimertinib therapy. And in this study, in a cohort of 98 patients with MET-amplified tumors confirmed by central testing, the overall response rate with the combination was 50% with a duration of response of 8.5 months. So definitely informing this guideline recommendation. Next, we had an update on recommendation in patients with ROS1-rearranged non-small cell lung cancer. For patients with ROS1-rearranged non-small cell lung cancer, the panel recommended specifically for patients who progressed after first-line ROS1 TKIs, the addition of taletrectinib as a new option alongside repotrectinib. And this recommendation was based on analysis of the results of the TRUST-I and TRUST-II studies, which showed that amongst 113 tyrosine kinase inhibitor-pretreated patients, taletrectinib achieved a confirmed overall response rate of 55.8% with a median duration of response of 16.6 months and a median PFS of 9.7 months, a very promising agent. Finally, for patients with HER2 exon 20 mutated non-small cell lung cancer, the panel added two new oral HER2 tyrosine kinase inhibitors, zongertinib and sevabertinib, as options in addition to T-DXd and after exposure to T-DXd. These recommendations are based on early phase data from two trials: the phase I Beamion LUNG-01 study, which evaluated zongertinib, and the phase I/II SOHO-01 study that evaluated sevabertinib. In this study, zongertinib demonstrated an overall response rate of 71% in previously treated patients, with an overall response rate of 48% amongst patients who had received prior HER2-directed ADCs including T-DXd. Sevabertinib in its early phase study showed an overall response rate of 64% in previously treated but HER2 therapy-naive patients, and an overall response rate of 38% in patients previously exposed to HER2-directed therapy. The panel believes that both agents had manageable toxicity profile and represent meaningful new options for this patient population. Brittany Harvey: Certainly, it's an active space of research, and I appreciate you reviewing the evidence underpinning all of these recommendations for our listeners. So, it's great to have these new options for patients in the later-line settings. And given all of these updates in both the first and the later-line settings, what should clinicians know as they implement this latest living guideline update, and how do these changes impact patients with non-small cell lung cancer? Dr. Sonam Puri: Some great questions, Brittany. I think for clinicians when implementing this update, I think about two practical steps. First is reiterating the importance of comprehensive biomarker testing. That is the only way to identify key drivers and resistance mechanisms that we are now targeting. And second, picking a first-line strategy that balances efficacy and toxicity and patient preference for your specific patient. I think informed decision-making, shared decision-making is more important than any time right now. It has always been important, but definitely very important now. For patients, this guideline brings recommendations on more personalized treatment options for both first-line and post-progression settings, which potentially means better outcomes. But it is also very important for our patients to continue to have informed conversations about side effects, time commitment, and what matters most to them with their providers. The panel in this version of the guideline specifically acknowledges the real-world barriers that prevent patients from receiving guideline-concordant therapy, including challenges with access to comprehensive molecular testing and treatment availability, and the panel emphasizes on the importance of shared decision-making, and we provide practical discussion points to help clinicians navigate these conversations with the patient. In addition, the panel has also addressed common real-world clinical complexities, such as treating elderly or frail patients, managing multiple chronic conditions, considerations around pregnancy and fertility, and certain disease scenarios such as oligoprogression or oligometastatic disease. And where available, the guideline summarizes this existing data to support informed individual decision-making in these complex situations. Brittany Harvey: Shared decision-making is really paramount, especially with all of the options and weighing the risks and benefits and considering the individual circumstances of each patient that comes before a clinician. We've talked a lot about all of the new studies that the panel has reviewed, but what other studies or areas of research is the panel examining for future updates to this living guideline as it continues to be updated on an ongoing basis? Dr. Sonam Puri: Yes, definitely, so much to look forward to, right? Looking ahead, the panel is closely monitoring several rapidly evolving areas that are likely to shape future updates of the guideline. This includes emerging data from ongoing later-phase studies, particularly the studies that are evaluating these new targeted agents moving to earlier lines of therapy, alongside studies evaluating additional combination strategies or more refined approaches to treatment sequencing. We're also closely watching advances in biomarker testing, the evolving understanding of resistance mechanisms, development of new targets, and promising therapeutic agents. I think ultimately the living guideline exists to help clinicians and patients navigate this rapidly evolving field, and we would like to ensure that scientific advances are rapidly translated into better, more personalized patient care. Brittany Harvey: Definitely. We'll look forward to those updates from those ongoing trials and future areas of research that you mentioned to provide better options for patients with non-small cell lung cancer and a driver alteration. So I want to thank you so much for your work to rapidly and continuously update this guideline, and thank you for your time today, Dr. Puri. Dr. Sonam Puri: Thanks so much.

Dr. Reuss, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer without driver alterations is updated on an ongoing basis. So, what prompted this latest update to the recommendations? Dr. Joshua Reuss: Our committee is tasked with making routine updates to the living guidelines and really keeping them living, right? So, evaluating new data as it is coming in to see, is this practice changing? Is this data that should inform and potentially alter our guideline recommendations so that practitioners and other care providers could really make the best treatment decisions for their patients? So that is something that happens on a more routine basis, but periodically, we are tasked with performing a more comprehensive update of our guideline where we really evaluate every one of our point recommendations, the data associated with these recommendations, to be sure that these are up to date, these are comprehensive, and to see if we need to alter anything in the language of these updates. Brittany Harvey: Excellent. Thank you for providing that background. And yes, this is truly a comprehensive update that goes through all the latest literature. Given that, I would like to review what has changed and what is new in the recommendations. So, what are the updated recommendations on first-line therapy for patients with stage IV non-small cell lung cancer without driver alterations? Dr. Joshua Reuss: So there are two main guidelines that we recommend from this panel. One is a driver mutation-positive guideline and the other is a driver mutation-negative guideline. And I think on first blush, one might look at kind of the recent flurry of approvals and new data and say, well, all the excitement, you know, is in the driver mutation-positive guideline. But I would say that the driver mutation-negative guideline is equally as important and really has several unique challenges associated with it. You know, first and foremost is that there are really a multitude of regimens that can be considered for any one patient. And how to choose between one can be quite difficult and a stressful challenge that clinicians can have, particularly since there are really no randomized studies comparing these regimens in a head-to-head fashion. In addition, you know, these guidelines are really broken down by two key factors. One is disease histology, so namely squamous versus non-squamous histology. And the other is PD-L1 status, broken down into one of three tertiles: PD-L1 high, which is greater than or equal to 50% expression; PD-L1 low, which is 1% to 49% expression; and then PD-L1 negative or unknown. So what you are really looking at, if you do that math, is really six unique patient subpopulations where we need to make a recommendation on one of the multitude of treatment regimens that is approved. And what that means is you are oftentimes really looking at subset and sub-subset level data to help inform clinicians in their treatment decision making, which can be quite challenging because as those small subsets of data is more and more parsed, there are many confounders that can be interjected there. And so I think the committee is tasked with really quite a challenge in terms of how to really communicate and broadcast that data in a way that informs clinicians in making a decision on what is the right treatment for their patient. Brittany Harvey: Absolutely. It can be challenging to interpret that subgroup data across several different studies that are reporting on different regimens and different outcomes. And I appreciate you mentioning the driver mutation-positive guideline as well. Listeners can check out the companion episode with Dr. Puri for more information on what is changed in the driver mutation-positive guideline. Based on that primer, what is new for first-line therapy for patients with stage IV non-small cell lung cancer without driver alterations? Dr. Joshua Reuss: Even though I will say there is not a lot of new trial data that was incorporated into this guideline, there were some updates and just some meaningful long-term data that we incorporated. I think first and foremost, there is a new top-level recommendation in this guideline pertaining to molecular testing, which is absolutely critical in both the driver mutation-positive and driver mutation-negative space. I think we tend to think that, oh, well, molecular testing really only pertains to then finding a driver mutation. But the lack of a mutation is absolutely critical as well, right? Because that is what leads us down the mutation-negative pathway. We also need this molecular testing to assess PD-L1 status. We are seeing emerging data on molecular mutations that might confer resistance to certain immunotherapy-based strategies. So the committee felt strongly that a recommendation on molecular testing is critical to include in both the driver mutation-positive guideline and the driver mutation-negative guideline. I will also say that we are now seeing five and six-year updates from some of the landmark trials of immunotherapy in driver mutation-negative non-small cell lung cancer. It is really incredible to see that in some of these trials, we are seeing very impressive durability of the treatment in the patient subsets that we are commenting on. In others, perhaps that durability is less clear, and I think that leads to challenges in making a recommendation on any one particular regimen. And I think that is nowhere more clear than in the squamous subset. I think that was one perhaps subtle change that is in this guideline where, particularly in the PD-L1 negative squamous population, the committee felt that no one regimen really was worthy of standing above the others. Sometimes I think it is important to really champion one unique regimen if we feel that the data is there to support it. But I think it is equally important to list multiple regimens where the data is less clear. I think another point is that while perhaps there were no new regimens that we have added or that led to other clear changes in the prioritization of one regimen over another, there are other unique data subsets that I think come into play in making a decision and that really are important when looking at the discussion on any one recommendation from this guideline. For example, we know there is emerging data on perhaps the significance of molecular alterations in KEAP1 or STK11 and how that might influence frontline decision-making. You know, there is not a prospective phase III trial in this population, but I think we still need to use that data in certain scenarios to make recommendations for a particular patient. Another example of a trial that, again, did not change our recommendations, but I think one can incorporate in their decision making is the KEYNOTE-598 trial. Now, this is not a new study, but what it studied was pembrolizumab versus pembrolizumab plus ipilimumab in a PD-L1 high subset, and found that the addition of ipilimumab to pembrolizumab in the PD-L1 high population did not significantly improve clinical efficacy. And so while pembrolizumab plus ipilimumab is not an approved regimen, it is hard to extrapolate that to our combination treatments that are approved. I think some clinicians might find that data valuable when making a frontline treatment decision on a patient who has PD-L1 high status. So a bit of a whirlwind tour, but I think there are still multiple factors that went into this guideline that are important to review when making treatment decisions for any one patient. Brittany Harvey: Absolutely. I think what you just mentioned in having that upfront molecular testing is really key for individualized patient care. And the evidence summaries that you provide in addition to the recommendations are really important for clinicians to be able to refer to as they are making decisions in their clinic. So then beyond those changes for first-line therapy, what is updated for second-line and subsequent therapies? Dr. Joshua Reuss: For second-line and subsequent therapies, we did see one new treatment recommendation join these ranks, and that was telisotuzumab vedotin. Telisotuzumab vedotin, quite a mouthful. That is an antibody-drug conjugate. I like to think of that as smart chemotherapy, targeted chemotherapy, where you are trying to utilize some aspect of a marker that is selectively expressed or overexpressed on the cancer surface to then shepherd in the anticancer molecule, a highly potent chemotherapeutic in the case of currently approved antibody-drug conjugates, to exert antitumor killing effect. So in this case, the antibody-drug conjugate telisotuzumab vedotin targets MET overexpression. So telisotuzumab is an antibody targeting MET, and that is conjugated to an MMAE highly potent chemotherapeutic payload called vedotin. So we know MET can be selectively expressed and overexpressed in non-small cell lung cancer in both driver mutation-positive and mutation-negative subsets. The data that led to this approval was from the phase II LUMINOSITY trial which evaluated telisotuzumab vedotin, or Teliso-V, in many subsets. But the subset that really showed promise and was expanded was the EGFR wild-type, non-squamous, non-small cell lung cancer population with MET overexpression. And so in 78 patients with high levels of expression, the response rate here was 34.6%, median progression-free survival of 5.5 months, and a median overall survival of 14.6 months. With an overall acceptable safety profile; grade 3 or higher adverse events, neuropathy was perhaps the most common at 7%, also increased ALT at 3.5%, and pneumonitis at 2.9%. Now this was phase II data that led to an accelerated approval. There is an ongoing phase III study randomizing patients with high expression to Teliso-V versus docetaxel. That is the phase III TeliMET study. But it is nice that we now have another option for patients, perhaps a more biomarker-directed option with, again, this MET overexpression. And again, it further reinforces the importance of molecular testing in patients with traditionally driver mutation-negative non-small cell lung cancer, whether that is upfront or at progression, and in particular utilizing immunohistochemistry to assess MET expression in these patients. And this does join another ADC that we had previously made an update in our recommendation, which is trastuzumab deruxtecan, which is approved for those patients with HER2-overexpressing non-small cell lung cancer. So just again to reiterate the importance of molecular testing in patients both at the outset of their treatment and upon progression on frontline therapy. Brittany Harvey: Definitely. It is great to have this new antibody-drug conjugate join the treatment options, and as you mentioned, very important in this case to have that molecular testing done at the outset and at progression. So then in your view, what should clinicians know as they implement this living guideline, and how do these changes impact patients with non-small cell lung cancer? Dr. Joshua Reuss: Because there are so many different regimens that one can consider for any one patient, I think it is easy to become overwhelmed and stress on, "Am I making the right choice for my patient?" And I think one of the key take home points is that in many cases, there is no one right regimen. And I think one has to weigh several factors. It is the treatment schedule. It is the toxicity profile. It is the molecular profile of the patient. It is the patient preference. You know, there are so many factors here. And I would like to draw the reader and viewer's attention to an important section of these guidelines, particularly the Patient and Clinician Communication section, where we have a box focused on discussion points between patients and clinicians, which I think focuses on several of the high-level points that one can emphasize in making these decisions, ranging on things from: what are the goals of the treatment? What are the risks and benefits to any one approach? What are comorbidities that should be factored in? Common concerns, toxicity management, clinical trial consideration. All of these factors that I think are incredibly important in making that frontline treatment decision and implementing a regimen that both the clinician and, more importantly, the patient feels comfortable with. Brittany Harvey: It is really important that there is shared decision-making in these scenarios. And I think that patient-clinician communication section can tease out some of those preferences from the patient end and talk through the risks and benefits of different regimens as well. As we mentioned at the top of this episode, this guideline is a living guideline and updated on an ongoing basis. So what is the panel examining and keeping an eye on for future updates to this guideline? Dr. Joshua Reuss: So I think there are a lot of exciting new therapies and more up-to-date trials that we are anxiously awaiting the results of on our committee, and I think the oncology community in general is awaiting the results of. When we will have these results, I think, is a bit of an open-ended question, but I can give some insight on several of the trials that our committee is really keeping a close eye on. One that we have mentioned for several guideline iterations is the ECOG-ACRIN INSIGNA trial. This is a phase III clinical trial comparing pembrolizumab versus pembrolizumab plus carboplatin and pemetrexed chemotherapy in PD-L1 positive, non-squamous, non-small cell lung cancer. We talk about there being different regimens that can be considered in PD-L1 positive and PD-L1 high subsets, namely immunotherapy alone or immunotherapy plus chemotherapy, but there is no direct head-to-head comparison here. So this trial hopefully will answer that question. It has now finished accrual. There are other very interesting molecules and trials. I think another interesting compound is ivonescimab. This is a PD-1/VEGF bispecific antibody that is currently approved in China as monotherapy in patients with PD-L1 positive non-small cell lung cancer based off of the HARMONi-2 trial, where the progression-free survival of this bispecific antibody, ivonescimab, appeared superior to pembrolizumab. And we are looking closely at ongoing trials to see if these results will be replicated in an ex-China population. And if so, I think it could have a real impact and change on our guidelines. Still other very interesting things. There are obviously confirmatory studies for antibody-drug conjugates, such as the TeliMET study that I alluded to earlier, and many promising antibody-drug conjugates, both bispecific and trispecific antibody-drug conjugates, that hopefully can inform practice. And then there are several unique subsets of populations that I think we now are utilizing data on to make decisions, but a lot of that is retrospective in small subsets where we do not have that prospective data. And there are several trials ongoing in some of these subsets to try to gain clarity on what regimen may be the best for patients. One example is the phase III TRITON trial, which is looking at comparing CTLA-4 containing regimen, particularly the POSEIDON regimen of durvalumab plus tremelimumab and chemotherapy, versus the KEYNOTE-189 regimen, which is pembrolizumab plus carboplatin and pemetrexed, in patients with non-squamous, non-small cell lung cancer that have alterations in either KRAS, KEAP1, and/or STK11. There is a lot of both preclinical and clinical data to suggest that patients with these alterations in STK11 and KEAP1 may be more resistant to a PD-1 based treatment approach, and perhaps the incorporation of CTLA-4 can lead to a more meaningful response in this unique subset. Obviously, that data, it is retrospective, it is in small subsets. And when you add in a CTLA-4 molecule, you are also introducing greater risk for toxicity. So this trial is going to be very important in elucidating: is there a benefit in that unique subset? Does that data that we see retrospectively in this small subset hold true when evaluated in a prospective fashion? So while our guideline, our most recent comprehensive panel update, may not have had a lot of new data in it that has influenced frontline treatment decision-making, I think the future is bright and there are a lot of novel studies and novel treatments on the horizon that will hopefully improve the outcomes for our patients. Brittany Harvey: Absolutely. We will look forward to the results of those ongoing trials to provide more options and particularly clarity for patients with non-small cell lung cancer and to inform this guideline and its many updates to come. So I want to thank you so much for your work to rapidly and continuously update this guideline, and thank you for your time today, Dr. Reuss. Dr. Joshua Reuss: Thank you so much.

Dr. Hope Rugo and Dr. Vivek Subbiah discuss innovative trial designs to enable robust studies for smaller patient populations, as well as the promise of precision medicine, novel therapeutic approaches, and global partnerships to advance rare cancer research and improve patient outcomes. TRANSCRIPT  Dr. Hope Rugo: Hello and welcome to By the Book, a podcast series from ASCO that features engaging conversations between editors and authors of the ASCO Educational Book. I am your host, Dr. Hope Rugo. I am the director of the Women's Cancers Program and division chief of breast medical oncology at the City of Hope Cancer Center [in Los Angeles]. The field of rare cancer research is rapidly transforming thanks to progress in clinical trials and treatment strategies, as well as improvements in precision medicine and next-generation sequencing that enable biomarker identification. According to the National Cancer Institute, rare cancers occur in fewer than 150 cases per million each year, but collectively, they represent a significant portion of all cancer diagnoses. And we struggle with the appropriate treatment for these rare cancers in clinical practice. Today, I am delighted to be joined by Dr. Vivek Subbiah, a medical oncologist and the chief of early-phase drug development at the Sarah Cannon Research Institute in Nashville, Tennessee. Dr. Subbiah is the lead author of a paper in the ASCO Educational Book titled "Designing Clinical Trials for Patients with Rare Cancers: Connecting the Zebras," a great title for this topic. He will be telling us about innovative trial designs to enable robust studies for small patient populations, the promise of precision medicine, and novel therapeutic approaches to improve outcomes, and how we can leverage AI now to enroll more patients with rare cancers in clinical trials. Our full disclosures are available in the transcript of this episode.  Dr. Subbiah, it is great to have you on the podcast today. Thanks so much for being here. Dr. Vivek Subbiah: Thank you so much, Dr. Rugo, and it is an honor and pleasure being here. And thank you for doing this podcast for rare cancers. Dr. Hope Rugo: Absolutely. We are excited to talk to you. And congratulations on this fantastic paper. It is such a great resource for our community to better understand what is new in the field of rare cancer research. Of course, rare cancers are complex and multifaceted diseases. And this is a huge challenge for clinical oncologists. You know, our clinics, of course, cannot be designed as we are being very uni-cancer focused to just be for one cancer that is very rare. So, oncologists have to be a jack of all trades in this area. Your paper notes that there are approximately 200 distinct types of rare and ultra-rare cancers. And, by definition, all pediatric cancers are rare cancers. Of course, clinical trials are essential for developing new treatment strategies and improving patient outcomes, and in your paper, you highlight some unique challenges in conducting trials in this rare cancer space. Can you tell us about the challenges and how really innovative trial designs, I think a key issue, are being tailored to the specific needs of patients with rare cancer and, importantly, for these trials? Dr. Vivek Subbiah: Rare cancers present a perfect storm of challenges. First, the patient populations are very small, which makes it really hard to recruit enough participants for traditional type trials. Second, these patients are often geographically dispersed across multiple cities, across multiple states, across multiple countries, across multiple zip codes. So, logistics become complicated. Third, there is often limited awareness among clinicians, which delays referrals and diagnosis. Add to that regulatory hurdles, funding constraints, and you can see why rare cancer trials are so tough to execute. To overcome these barriers, we are seeing some really creative novel trial designs. And there are four different types of trial designs that are helping with enrolling patients with rare cancers. The first one is the basket trial. So let us talk about what basket studies are. Basket studies group patients based on shared genetic biomarkers or shared genetic mutations rather than tumor type. So instead of running separate 20 to 30 to 40 trials, you can study one therapy across multiple cancers. The second type of trial is the umbrella trial. The umbrella trials flip that concept of basket studies. They focus on one cancer type but test multiple targeted therapies within it. The third category of innovative trials are the platform studies. Platform trials are another exciting innovation. They allow new treatment arms to be added or removed as the data matures and as the data evolves, making trials more adaptive and efficient. The final category are decentralized tools in traditional trials, which are helping patients participate closer to where they are so that they can sleep in their own bed, which is, I think, a game changer for accessibility.  These designs maximize efficiency and feasibility for rare cancer research and rare cancer clinical trials. Dr. Hope Rugo: I love the idea of the platform trials that are decentralized. And I know that there is a trial being worked on with ARPA-H (Advanced Research Projects Agency for Health) funding in triple-negative breast cancer as well as in lung cancer, I think, and others with this idea of a platform trial. But it is challenged, I think, by precision medicine and next-generation sequencing where some patients do not have targetable markers, or there isn't a drug to target the marker. I think those are almost the same thing. We have really seen that these precision medicine ideas and NGS have moved the needle in helping to identify genetic alterations. This helps us to be more personalized. It actually helps with platform studies to customize trial enrollment. And we hope that this will result in better outcomes. It also allows us, I think, to study drugs even in the early stage setting more effectively. How can these advances be best applied to the future of rare cancers, as well as the challenges of not finding a marker or not having a drug? Dr. Vivek Subbiah: Thank you so much for that question. I think precision medicine and next-gen sequencing, or NGS, are truly the backbone of modern precision oncology. They have transformed how we think about cancer treatment. Instead of treating based on where the tumor originated or where the tumor started, we now look at the genetic blueprint of cancer. The NGS or next-gen sequencing allows us to sequence millions of DNA fragments quickly. Twenty, 30 years ago, they said we cannot sequence a human genome. Then it took almost a decade to sequence the first human genome. Right now, we have academic centers and commercial sequencing companies that are really democratizing NGS across all sites, not just in academic centers, across all the community sites, so that NGS is now accessible. This means that we can identify these actionable alterations like picking needles in haystacks, like NTRK fusions, RET fusions, or BRAF V600E alterations, high tumor mutational burden. This might occur across not one tumor type, across several different tumor types. So for rare cancers, this is critical because some of these mutations often define the best treatment option. Here is why this matters. Personalized therapy, right? Instead of a one-size-fits-all approach, we can tailor treatment to the patient's unique molecular profile. For trial enrollment, this can definitely help because patients can join biomarker-driven trials even if their cancer type is rare or ultra-rare. NGS technology has also helped us in designing rational studies. Many times monotherapy does not work in these cancers. So we are thinking about rational combination strategies. So NGS technology is helping us. Looking ahead, I see NGS becoming routine in clinical practice, not just at major niche academic centers, but everywhere. We will see more tumor-agnostic approvals, more molecular tumor boards guiding treatment decisions in real time. And I think we are seeing an expanded biomarker setup. Previously, we used to have only a few drugs and a handful of mutations. Now with homologous recombination defects, BRCA1/2 mutation, and expanding the HRD and also immunohistochemistry, we are expanding the biomarker portfolio. So again, I personally believe that the future is precision. What I mean by precision is delivering the right drug to the right patient at the right time. And for rare cancers, this isn't just progress. It is survival. And it is maybe the only way that they can have access to these cutting-edge precision medicines. Dr. Hope Rugo: That is so important. You mentioned an important area we will get to in a moment, the tumor-agnostic therapies. But as part of talking about that, do you think that the trials should also include just standard therapies? You know, who do you give an ADC to and when with these rare cancers? Because some of them do not have biomarkers to target and it is so disappointing for patients and providers where you are trying to screen a patient for a trial or a platform trial where you have one arm with this mutation, one arm with that, and they do not qualify because they only have a p53 loss, you know? They just do not have the marker that helps them. But we see this in breast cancer all the time. And it is tough because we don't have good information on the sequencing. So I wonder, you know, just because for some of these rare cancers it is not even clear what to use when with standard treatments. And then that kind of gets into this idea of the tumor-agnostic therapies that you mentioned. There are a lot of new treatments that are being evaluated. We have seen approval of some treatments in the last few years that are tumor-agnostic and based on a biomarker. Is that the best approach as we go forward for rare cancers? And what new treatment options are most exciting to you right now? Dr. Vivek Subbiah: Tumor-agnostic therapies, really close to my heart, are real breakthrough therapies and represent a major paradigm shift in oncology. Traditionally, for the broad listeners here, we are used to thinking about designing clinical trials and therapy like where the cancer originated, breast cancer, kidney cancer, prostate cancer, lung cancer. A tumor-agnostic therapy flips that model. Instead of focusing on the organ, they target the specific genetic alteration or biomarker that drives cancer growth regardless of where the tumor started, regardless of the location of the tumor, regardless of the zip code of the tumor. So why is this so important for rare cancers? Because many rare cancers share molecular features with more common cancers. For instance, NTRK fusion might occur in pediatric sarcoma, a salivary gland tumor, or a thyroid cancer. Historically, each of these would require separate trials, which is nearly impossible, unfeasible to conduct in these ultra-rare cancers like salivary gland cancer or pediatric sarcomas. Tumor-agnostic therapies allow us to treat all those cancers with the same targeted drug if they share that biomarker. Again, we are in 2025. The first tissue-agnostic approval, the historic precedent, was in fact an immunotherapy. Pembrolizumab was approved in 2017, May 2017, as the first immunotherapy to be approved in a tumor-agnostic way for a genomic biomarker, for MSI-High and dMMR cancers. Then came the NTRK inhibitors. So today we have not one, not two, but three different NTRK inhibitors: larotrectinib, entrectinib, and repotrectinib, which show response rates of nearly more than 60 to 75% across a handful of dozens and dozens of cancer types. Then, of course, we have RET inhibitors like selpercatinib, which is approved tissue-agnostic, and pralsetinib, which also shows tissue-agnostic activity across multiple cancers. And more recently, combination therapy with a BRAF and MEK combination, dabrafenib and trametinib, received tumor-agnostic approval for all BRAF V600E tumors with the exception of colorectal cancer. And even recently, you mentioned about antibody drug conjugates. Again, I think we live in an era of antibody drug conjugates. And Enhertu, trastuzumab deruxtecan, which was used first in breast cancer, now it is approved in a histology-agnostic manner for all HER2-positive tumors defined by immunohistochemistry 3+. So again, beyond NGS, now immunohistochemistry for HER2 is also becoming a biomarker. So again, for the broad listeners here, in addition to comprehensive NGS that may allow patients to find treatment options for these rare cancers for NTRK, RET, and BRAF, immunohistochemistry for HER2 positivity is also emerging as a biomarker given that we have a new FDA approval for this. So I would say personally that these therapies are game changers because they open doors for patients who previously had no options. Instead of waiting for years for a trial in their specific cancer type, they can access a treatment based on their molecular profile. I think it is precision medicine at its finest and best. Looking ahead, the third question you asked me is what is exciting going on? I think we will see more of these approvals. My hope is that today, I think we have nine to ten approvals. My hope is that within the next 25 to 50 years, we will have at least 50 to 100 drugs approved in this space based on a biomarker, not based on a location of the tumor type. Drug targeting rare alterations like FGFR2 fusions, FGFR amplifications, ALK fusions, and even complex signatures like high tumor mutational burden. I think we will be seeing hopefully more and more drugs approved. And as sequencing becomes routine, we will identify more patients for these therapies. I think for rare cancers, this is not just innovative approach. This is essential for them to access these novel precision medicines. Dr. Hope Rugo: Yeah, that is such a good point. I do think it is critical. Interestingly in breast cancer, it hasn't been, you know, there is always like two patients in these tumor-agnostic trials, or if that. You know, I think I have seen one NTRK fusion ever. I think that highlights the importance for rare cancers. And you know, I am hoping that that will translate into some new directions for some of our rarer and impossible-to-treat subtypes of breast cancer. It is this kind of research that is really going to make a difference. But what about those people who do not have biomarkers? What if you do not fit into that? Do you think there is a possibility of trying to do treatments for rare cancers in some prospective way that would help with that? You know, it is really a huge challenge. Dr. Vivek Subbiah: Absolutely. I think, you know, you're right, usually many of these rare cancers are driven by specific biomarkers. And again, some of the pediatric salivary gland tumors or pediatric sarcomas like fibrosarcomas, they are pathognomonic with NTRK fusions. And again, given that we have a tumor-agnostic approval, now these patients have access to these therapies. And I do not think that we would have had a trial just for pediatric fibrosarcomas with NTRK fusions. So that is one way. Another way is SWOG, right? The SWOG DART [1609] had this combination dual checkpoint, it was called the DART study dual combination chemotherapy with ipi/nivo. Now here the rare cancer subtype itself becomes a biomarker and they showed activity across multiple rare cancer subtypes. They didn't require a biomarker. As long as it was a rare or ultra-rare cancer, these patients were enrolled into the SWOG DART trial and multiple arms have read out. Angiosarcoma, Kaposi sarcoma, even gestational trophoblastic disease. Again, they have shown responses in these ultra-rare, rare cancers. Sometimes they might be seeing one or two cases a whole year. And I think this SWOG effort, this cooperative group effort, really highlighted the need for such studies without biomarkers as well. Dr. Hope Rugo: That is such a fantastic example of how to try and treat patients in a collaborative way. And in the paper, you also emphasize the need for collaborative research efforts, you know, uniting resource expertise across different ways of doing research. So cooperative groups, advocacy organizations that can really help advance rare cancer research, improve access to new therapies, and I think importantly influence policy changes. I think this already happened with the agnostic approvals. Could you tell us more about that? How can we move forward with this most effectively? Dr. Vivek Subbiah: Personally, I believe that collaboration is absolutely critical and essential for rare cancer research. No single institution, no single individual, or no single state or entity can tackle these challenges alone. The patient populations are small and dispersed. So pooling resources is the only way to run these meaningful trials. Again, it is not like singing, it is like putting a huge, huge, I would say, an opera piece together. It is not a solo, vocal therapy, but rather putting a huge opera piece like Turandot. You know, you mentioned cooperative groups. Cooperative groups, as I mentioned earlier, the SWOG DART program, the ASCO [TAPUR study]. ASCO is doing a phenomenal work of the TAPUR study. Again, this ASCO TAPUR program has enrolled so many patients with rare cancers who otherwise would not have treatment options. NCI-MATCH, the global effort, right? NCI-MATCH and the ComboMATCH are great examples. They bring together hundreds of sites, thousands of clinicians to run large-scale trials that would be impossible for any individual center or institution. These trials have already changed practice. For instance, the DART demonstrated the power of immunotherapy in rare cancers and influenced NCCN guidelines. One of the arms of the NCI-MATCH study from the BRAF V600E arm contributed towards the BRAF V600E tissue-agnostic approval. So, the BRAF V600E tissue-agnostic approval was by a pooled analysis of several studies. The ROAR study, the Rare Oncology Agnostic Research study, the NCI-MATCH dataset of tumor-agnostic cohort, and another pediatric trial, and also evidence from literature and evidence of case reports. And all this pooled analysis contributed to the tissue-agnostic approval of BRAF V600E across multiple rare cancers. There are several patient advocacy organizations which are the real unsung heroes here. Groups like, for instance, we mentioned in the paper, Target Cancer Foundation, don't just raise awareness for rare cancer research, they actively connect patients to trials providing financial, emotional support, and even run their own studies like the TRACK trial. They also influence policy to make access easier. On a global scale, initiatives like DRUP in the Netherlands, the ROME study in Italy, the PCM4EU in Europe are expanding precision medicine across these borders. These collaborations accelerate research, improve trial enrollment, and ensure patients everywhere can have access to these cutting-edge therapies. Again, it is truly a team effort, right? It is a multi-stakeholder approach. Researchers, clinicians, investigators, industry, regulators, academia, patients, patient advocates, and their caregivers all working together. And it takes a village. Dr. Hope Rugo: Absolutely. I mean, what a nice response to that. And I think really exciting and it is great to see your passion about this as well. But it helps all of us, I think, getting discouraged in treating these cancers to understand what is happening moving forward. And I think it is also a fabulous opportunity for our junior colleagues as they rise up in academics to be involved in these international collaborative efforts which are further expanding. One of the things that comes up for clinical trials for patients, and I think it is highlighted with rare cancers because, as you mentioned, people are all over the place, you know, they are so rare. They are all far away. Our patients are always saying to us, "Should I go here for a phase 1 trial?" Can you talk a little bit about how we can overcome these financial and geographic burdens for the patients? You talked about having trials locally, but it is a big financial and just social burden for patients. Dr. Vivek Subbiah: Great point. Financial cost is a major barrier in rare cancer clinical trials. It is a major barrier not just in rare cancer clinical trials, but in clinical trials in general. The economics of rare cancer research are one of the toughest challenges we face. Developing a new drug is already expensive, often billions of dollars. On an average, it takes 2 billion dollars or 2.8 billion dollars according to some data from drug discovery to approval. For rare cancers, the market is tiny, which means the pharmaceutical companies have really little financial incentive to invest. That is why initiatives like the Orphan Drug Act were created to provide tax credits, grants, and market exclusivity to encourage development for rare diseases. Clinical trials themselves are expensive because the small patient populations mean longer recruitment times and higher per-patient costs. Geographic dispersion, as you mentioned, for the patients adds travel, coordination. That is why we need to think out of the box about decentralized trial infrastructure so that we can mitigate some of these expenses. Complex trial designs like basket or platform trials sometimes require sophisticated data systems and regulatory oversight. That is a challenge. And I think some of the pragmatic studies like ASCO TAPUR have overcome those challenges. Advanced technologies like next-gen sequencing and molecular profiling also add significant upfront cost to this. Funding is also limited because rare cancers receive less attention compared to common cancers. Public funding and cooperative group trials help a lot, but I think they cannot cover everything. Patient advocacy organizations sometimes step in to bridge these gaps, but sustainable financing remains a huge challenge. So, the bottom line is without financial incentives and collaborating funding models, many promising therapies for rare cancers would never make it to patients. That is why we need system-wide policy changes, global partnerships, and innovative, effective, seamless trial designs which are so critical so that they can help reduce the cost and make research feasible so that we can deliver the right drug to the right patient at the right time. Dr. Hope Rugo: There is a lot of excitement about the future integration of AI in screening. Just at the San Antonio Breast Cancer meetings, we have a number of different presentations about AI to find markers, even like HER2, and using AI where you would screen and then match patients to clinical trials. Do you have any guidance for the rare cancer community on how to leverage this technology in order to optimize patient enrollment and, I think, identification of the best treatment matches? Dr. Vivek Subbiah: I think artificial intelligence, AI, is a game-changer in the making. Right now, clinical trial is clunky. Matching patients to trial is often manual, time consuming, laborious. You need a lot of personnel to do that. AI can automate this process by analyzing genomic data, medical records, and trial eligibility criteria to find the best matches quickly, accurately, and effectively. For the community, the key is to invest in data standardization and interoperability because AI needs clean, structured data to work effectively.

Dr. Monty Pal and Dr. Hope Rugo discuss advances in antibody-drug conjugates for various breast cancer types as well as treatment strategies in the new era of oral SERDs for HR-positive breast cancer. TRANSCRIPT Dr. Monty Pal: Hello, and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist and vice chair of academic affairs here at the City of Hope Comprehensive Cancer Center, Los Angeles. Today, I'm thrilled to be joined by Dr. Hope Rugo, an internationally renowned breast medical oncologist and my colleague here at City of Hope, where she leads the Women's Cancers Program and serves as division chief of breast medical oncology. Dr. Rugo is going to share with us exciting advances in antibody-drug conjugates (ADCs) that are expanding treatment options in various breast cancer types. She'll also address some of the complex questions arising in the new era of oral SERDs (selective estrogen receptor degraders) that are revolutionizing treatment in the hormone receptor-positive breast cancer space. Our full disclosures are available in the transcript of this episode.  Dr. Rugo, welcome, and thanks so much for being on the podcast today. Dr. Hope Rugo: Thank you. Pleasure to be here. Dr. Monty Pal: So, I'm going to switch to first names if you don't mind.  The first topic is actually a really exciting one, Hope, and this is antibody-drug conjugates. I don't know if I've ever shared this with you, but I actually started my training at UCLA, I was a med student and resident there, and it was in Dennis Slamon's lab. I worked very closely with Mark Pegram and a handful of others. This is right around the time I think a lot of HER2-directed therapies were really evolving initially in the clinics. Now we've got antibody-drug conjugates. Our audience is well-familiar with the mechanism there but tell us about how ADCs have really started to reshape therapy for HER2-positive breast cancer. Dr. Hope Rugo: Yeah, I mean, this is a really great place to start. I mean, we have had such major advances in breast cancer just this year, I think really changing the paradigm of treating patients. But HER2-positive disease, we've been used to having sequenced success of new agents. And I think the two biggest areas where we've made advances in HER2-positive disease, which were remarkably advanced this year in 2025, have been in antibody-drug conjugates with trastuzumab deruxtecan and with new oral tyrosine kinase inhibitors (TKIs) that have less of a target on EGFR and more on HER2, so they have an overall more tolerable toxicity profile and therefore a potentially better efficacy in the clinic. At least that's what we're seeing with these new strategies that we couldn't really pursue in the past because of toxicities of the oral TKIs. So, although our topic is ADCs, I'm going to include the TKI because it's so important in our thinking about treating HER2-positive disease. In the metastatic setting, we've seen these remarkable improvements in progression-free and overall survival in the second-line setting with T-DXd, or trastuzumab deruxtecan, compared to T-DM1. And then sequencing ADCs with giving T-DXd after T-DM1 was better than an oral tyrosine kinase or a trastuzumab combination with standard chemotherapy. That was DESTINY-Breast03 and DESTINY-Breast02. So, then we've had other trials since then, and T-DXd has moved into the early-stage setting, which I'll talk about in just a moment. But the next big trial for T-DXd in HER2-positive disease was moving it to the first-line setting to supplant what has become an established treatment for now quite a long time: the so-called CLEOPATRA regimen, which used the combined antibodies trastuzumab, pertuzumab with a taxane as first-line therapy. And then we've proceeded on with maintenance with ongoing HP for patients with responding or stable disease. And we'd seen long-term data showing, you know, at 8 years there was a group of patients whose cancers had never progressed and continued improved overall survival. So, T-DXd was studied in DESTINY-Breast09, either alone or in combination with pertuzumab compared to THP. The patient population had received a little bit more prior treatment, but interestingly, not a lot compared to CLEOPATRA. And they designed the trial to be T-DXd continued until progression with or without pertuzumab versus THP, which would go for six cycles and then stop around six cycles, and then stop and continue HP. Patients who had hormone receptor-positive disease could use hormone therapy, and this is one of the issues with this dataset because, surprisingly in this dataset and one other I'll mention, very few patients took hormone therapy. And even in the maintenance trial, the HER2CLIMB-05, less than 50% took hormone therapy as maintenance. This is kind of shocking to me and highlights an area of really important education, that outcome is improved when you add endocrine therapy for hormone receptor-positive HER2-positive metastatic disease in the maintenance phase, and it's a really important part of treatment. But suffice it to say, you know, you're kind of studying continued chemo versus stopping chemo in maintenance. And T-DXd, as we all expected, in combination with pertuzumab was superior to THP in terms of progression-free survival, really remarkably improved. And you could stop the chemo with toxicity, but most people continued it with T-DXd. Again, not a lot of people got hormone therapy, which is an issue, and you stop the chemo in the control arm. So, this has brought up a lot of interest in trying to use T-DXd as an induction and then go to maintenance, much as we do with the CLEOPATRA regimen with hormone therapy. But it brings up another issue. So first, T-DXd is superior; it's a great treatment. Not everybody needs to have it because we don't know whether it's better to give T-DXd first or second with progression - that we need a little bit longer follow-up. But just earlier this week, interestingly, the third week of December, the U.S. FDA approved T-DXd in the DESTINY-Breast09 approach with pertuzumab. So as I mentioned earlier, there was a T-DXd-alone arm; that arm has not yet reported. So very interesting, we don't know if you need pertuzumab or not. So what about the maintenance? That's the other area where we've made a huge advance here. So, we all want to stop chemo and we want to stop T-DXd. You don't want somebody being nauseated for two years while they're on treatment, and also there's a small number of patients with mostly de novo metastatic HER2-positive disease who are cured of their disease. We'd like to expand that, and I think these new drugs give us the opportunity to improve the number of patients who might be cured from metastatic disease. So the first maintenance study we saw was adding palbociclib, the CDK4/6 inhibitor, to endocrine therapy and HP, essentially. There, we had a remarkable improvement in progression-free survival difference of 15.2 months: 29 to 44 months, really huge. At San Antonio this year, we saw data with this oral tyrosine kinase inhibitor tucatinib, already showed it was great in a triplet, but as maintenance in combination with HP, it showed also a remarkable improvement in progression-free survival. But the numbers were all shifted down. So in PATINA, the control arm was in the 24-month range; here it was the tucatinib-HP arm that was in the 25 months and 16 months for control. So there was a differential benefit in ER-negative and ER-positive disease. So I think we're all thinking that our ideal approach moving forward would be to give T-DXd to most patients, we see how they do, and treat to best response. And then, stop the T-DXd, start HP, trastuzumab, pertuzumab for ER-negative, with tucatinib for ER-positive with palbociclib. We also have early data that suggests that both approaches may reduce the development of brain metastases, an issue in HER2-positive disease, and delay time to progression of brain metastases as seen in HER2CLIMB-05 in very early data - small numbers, but still quite intriguing that you might delay progression of brain metastases with tucatinib that clearly has efficacy in the brain.  So, I think that this is a hugely exciting advance for our patients, and these approaches are quickly moving into the early stage setting. T-DXd compared to standard chemo, essentially followed by THP, so a sequenced approach resulted in more pathologic complete responses than a standard THP-AC-type neoadjuvant therapy. T-DXd alone for eight cycles wasn't better, and that's interesting. We still need the sequenced non-cross-resistant chemo. But I think even more importantly, the data from DESTINY-Breast05 looking at T-DXd versus T-DM1 in patients with residual disease after neoadjuvant HER2-targeted therapy showed a remarkable improvement in invasive disease-free survival with T-DXd versus T-DM1, and quite early. It was a high-risk population, higher risk than the T-DM1 trial with KATHERINE, but earlier readout with a remarkable improvement in outcome. We expect to be FDA approved sometime in the first half of 2026. So then we'll get patients who've already had T-DXd who get metastatic disease. But my hope is that with T-DXd, maybe with tucatinib in the right group of patients or even sequenced in very high-risk disease, that we could cure many more patients with early-stage HER2-positive breast cancer and cure a subset, a greater subset of patients with de novo metastatic disease. Dr. Monty Pal: That's brilliant. And you tackled so many questions that I was going to follow up with there: brain metastases, etc. That was sort of looming in my mind. I mean, general thoughts on an ADC versus a TKI in the context of brain mets? Dr. Hope Rugo: Yeah, it's an interesting question because T-DXd has shown quite good efficacy in this setting. And tucatinib, of course, had a trial where they took patients with new brain mets, so a larger population than we've seen yet for the T-DXd trials, and saw that not only did they delay progression of brain metastases and result in shrinkage of existing untreated brain mets, but that patients who develop a new brain met, they could stay on the same assigned treatment. They got stereotactic radiation, and then the patients who were on tucatinib with trastuzumab and capecitabine had a further delay in progression of brain mets compared to those on the placebo arm, even after treatment of a new one that developed on treatment. So, I think it's hard. I think most of us for a lot of brain mets might start with the tucatinib approach, but T-DXd is also a very important treatment. You know, you're kind of trading off a diarrhea, some liver enzyme elevations with tucatinib versus nausea, which you really have to work on managing because it can be long-delayed nausea, and this risk of ILD, interstitial lung disease, that's about 12%, with most but not all trials showing a mortality rate from interstitial lung disease of just under 1 percent. In the early-stage setting, it was really interesting to see that with T-DXd getting four cycles in the neoadjuvant setting, a lot less ILD noted than the patients who got up to 14 cycles, as I think they got a median of 10 cycles in the post-surgical setting, there was a little bit more ILD. But I think we're going to be better and better at finding this earlier and preventing mortality by just stopping drug and treating earlier with steroids. Dr. Monty Pal: And this ILD issue, it always seems to resurface. There are drugs that I use in my kidney cancer clinic, everolimus, common to perhaps the breast cancer clinic as well, pembrolizumab, where I think the pattern of pneumonitis is quite different, right? What is your strategy for recognizing pneumonitis early in this context? Dr. Hope Rugo: Well, it is, and you know, having done the very early studies in everolimus where we gave it in the neoadjuvant setting and we're like, "Hmm, the patient came in with a cough. What's going on?" You know, we didn't know. And you have mouth sores, you know, we were learning about the drug as we were giving it. What we don't do with everolimus and CDK4/6 inhibitors, for example, is grade 1 changes like radiation pneumonitis, we don't stop, we don't treat it. We only treat for symptoms. But because of the mortality associated with T-DXd, albeit small, we stop drug for grade 1 imaging-only asymptomatic pneumonitis, and some of us treat with a half dose of steroids just to try and hasten recovery. We've actually now published or presented a couple of datasets from trials, a pooled analysis and a real-world analysis, that have looked at patients who were retreated after grade 1 pneumonitis or ILD and tolerated drug very well and none of them died of interstitial lung disease, which was really great to see because you can retreat safely and some of these patients stayed on for almost a year benefiting from treatment. So, there's a differential toxicity profile with these drugs and there are risk factors which clearly have identified those at higher risk: prior ILD, for example. A French group said smoking; other people haven't found that, maybe because they smoked more in France, I don't know. And being of Japanese descent is quite interesting. The studies just captured that you were treated in Japan, but I think it's probably being of Japanese descent with many drugs that increases your risk of ILD. And, you know, older patients, people who have hypoxia, those are the patients. So, how do we do this? With everolimus, we don't have specific monitoring. But for T-DXd we do; we do every nine weeks to start with and then every 12 weeks CT scans because most of the events occur relatively early. Somebody who's older and at higher risk now get the first CT at six weeks. Dr. Monty Pal: This is super helpful. And I have to tell you, a lot of these drugs are permeating the bladder cancer space which, you know, is ultimately going to be a component of my practice, so thank you for all this. We could probably stay on this topic of HER2-positive disease forever. I'm super interested in that space still. But let me shift gears a little bit and talk about triple-negative breast cancer and this evolving space of HR-positive, HER2-low breast cancer. I mean, tell us about ADCs in that very sort of other broad area. Dr. Hope Rugo: So triple-negative disease is the absolute hardest subset of disease that we have to treat because if you don't have a great response in the early stage setting, the median survival is very short, you know, under two years for the majority of TNBCs, with the exception of the small percentage of low proliferative disease subsets. The co-question is what do we do for these patients and how do we improve outcome? And sacituzumab govitecan has been one strategy in the later line setting that was shown to improve progression-free and overall survival, the Trop-2 ADC. We had recently three trials presented with the two ADCs, sacituzumab govitecan and the other Trop-2 ADC that's approved for HR-positive disease, datopotamab deruxtecan. And they were studied in the first-line setting. Two trials with SG, sacituzumab govitecan, those trials, one was PD-L1 positive, ASCENT-04. That showed that SG with a checkpoint inhibitor was superior, so pembrolizumab was superior to the standard KEYNOTE-355 type of treatment with either a taxane or gemcitabine and carboplatin with pembrolizumab for patients who have a combined positive score for PD-L1, 10 or greater. So, these are patients who are eligible for a checkpoint inhibitor, and SG resulted in an improved progression-free survival.  The interesting thing about that dataset is that few patients had received adjuvant or neoadjuvant checkpoint inhibitor, which is fascinating because we give it to everybody now. But access is an issue and timing of the study enrollment was an issue. The other thing which I think we've all really applauded Gilead for is that there was automatic crossover. So, you could get from the company, to try and overcome some of the enormous disparities worldwide in access to these life-saving drugs, you could get SG through the company for free once you had blinded independent central review confirmation of disease progression. Now, a lot of the people who got the SG got it through their insurance, they didn't bill the company, but 80 percent of patients in the control arm received SG in the second-line setting. So that impacts your ability to look at overall survival, but it's an incredibly important component of these trials. So then at ESMO, we saw the data from SG and Dato-DXd in the first-line metastatic setting for patients who either had PD-L1-negative disease or weren't eligible for an immunotherapy. For the Dato study, TROPION-Breast02, that was 10 percent of the patients who had PD-L1-positive disease but didn't get a checkpoint inhibitor, and for the ASCENT-03 trial population it was only 1 percent. Importantly, the trials allowed patients who relapsed within a year of receiving their treatment with curative intent, and the Dato study, TB-02, allowed patients who relapsed while on treatment or within the first six months, and that was 15 percent of the 20 percent of early relapsers. The ASCENT trial, ASCENT-03, had 20 percent who relapsed between 6 and 12 months. The drugs were better than standard of care chemotherapy, the ADCs in both trials, which is very nice. Different toxicity profiles, different dosing intervals, but better than standard of care chemotherapy in the disease that's hardest for us to treat. And importantly, when you looked at the subset of early relapsers, those patients also did better with the ADC versus chemotherapy, which is incredibly important. And we were really interested in that 15 percent of patients who had early relapse. I actually think that six months thing was totally contrived, invented, you know, categorization and doesn't make any sense, and we should drop it. But the early relapsers were 15 percent of TB-02 and Dato was superior to standard of care chemo. We like survival, but the ASCENT trial again allowed the crossover to an approved ADC that improved survival and 80 percent of patients crossed over. In the Dato trial, they did not allow crossover, they didn't provide Dato, which isn't approved for TNBC but is for HR-positive disease, and they didn't allow, of course, pay for SG. So very few patients actually crossed over in their post-treatment data and in that study, they were able to show a survival benefit. So actually, I think in the U.S. where we can use approved drugs already before there's a fixed FDA approval, that people are already switching to use SG or Dato in the first-line setting for metastatic TNBC that's both PD-L1 positive for SG and PD-L1 negative for both drugs. And I think understanding the toxicity profiles of the two drugs is really important as well as the dosing interval to try and figure out which drug to use. Dr. Monty Pal: Brilliant. Brilliant. Well, I'm going to shift gears a little bit. ADCs are a topic, again, just like HER2-positive disease we could stay on forever. Dr. Hope Rugo: Huge. Yes. Dr. Monty Pal: But we're going to shift gears to another massive topic, which is oral SERDs. In broad strokes, right, this utilization of CDK4/6 inhibitors in the context of HR-positive breast cancer is obviously, you know, a paradigm that's been well established at this point. Where do we sequence in oral SERDs? Where do they fit into this paradigm? Dr. Hope Rugo: Ha! This is a rapidly changing area; we keep changing what we're saying every other minute. And I think that there are three areas of great interest. So one is patients who develop ESR1 mutations that allow constitutive signaling through the estrogen receptor, even when there's not estrogen around, and that is a really important mutation that is subclonal; it develops under the pressure of treatment in about 40 percent of patients. And it doesn't happen when you first walk in the door. And what we've seen is that oral SERDs as single agents are better than standard single-agent endocrine therapy in that setting. The problem that we've had with that approach is that we're now really interested in giving targeted agents with our endocrine therapies, not just in the first-line setting where CDK4/6 inhibitors are our standard of care with survival benefit for ribociclib and, you know, survival benefit in subsets with other CDK4/6 inhibitors, and abemaciclib with a numeric improvement. So we give it first line. The question is, what do you do in the second-line setting? Because of the recent data, we now believe that oral SERDs should be really given with a targeted agent. And some datasets which were recently presented, which I think have helped us with that, have been EMBER-3 and then the most recently evERA BC, or evERA Breast Cancer, that looked at the oral SERD giredestrant with everolimus compared to standard of care endocrine therapy with everolimus, where 100 percent of patients received prior CDK4/6 inhibitor and showed a marked improvement in progression-free survival, including in the subsets of patients with a short response, 6-12 months of prior response to CDK4/6 inhibitor and in those who had a PIK3CA pathway mutation. The thing is that the benefit looks like it's much bigger in the ESR1 mutant population, although response was better, PFS wasn't better in the wild type. So, we're still trying to figure that out. We also saw EMBER-3 with imlunestrant and abemaciclib as a second line. Not everybody had had a prior CDK4/6 inhibitor; they compared it to imlunestrant alone, but still the data was quite striking and seemed to cross the need for ESR1 mutations. And then lastly, we saw data from the single arms of the ELEVATE trial looking at elacestrant with everolimus and abemaciclib and showed these really marked progression-free survival data, even though single-arm, that crossed the mutation status. At least for the everolimus combination, abemaciclib analysis is still to come in the mutated subgroups. But really remarkable PFS, much longer.  Single-agent fulvestrant after CDK4/6 inhibitor AI has a PFS in like the three-month range and in some studies, maybe close to five months. These are all at 10-plus months and really looking very good. And so those questions are, is it ESR1 mutation alone? Is it all comers? We'd like all comers, right? We believe in the combination approach and we're learning more about combinations with drugs like capivasertib and other drugs as we move forward. Everybody now wants to combine their targeted agent with an oral SERD because they're clearly here to stay with quite remarkable data. The other issue, so the second issue in the metastatic setting is, does it make a difference if we change to an oral SERD before radiographic imaging evidence of progression? And that was the question asked in the SERENA-6 trial where patients had serial monitoring for the presence of ESR1 mutations in ctDNA. And those who had them without progression on imaging could be randomized to switch to camizestrant with the same CDK4/6 inhibitor or stay on their same AI CDK4/6 inhibitor. And they showed a difference in progression-free survival that markedly favored camizestrant. But interestingly, the people who were on the standard control arm had an ESR1 mutation, we think AIs don't work, they stayed on for nine more months. The patients who were on the camizestrant stayed on for more than 16 months. And they presented some additional subset data which showed the same thing: follow-up PFS data, PFS2, all beneficial in SERENA-6 at the San Antonio [Breast Cancer Symposium]. So, we're still a little bit unclear about that. They did quality of life, and pain was markedly improved. They had a marked delayed time to progression of pain in the camizestrant arm. So this is all a work in progress, trying to understand who should we switch without progression to an oral SERD based on this development of this mutation that correlates with resistance. And, you know, it's interesting because the median time to having a mutation was 18 months and the median time to switch was almost 24 months. And then there were like more than 3,000 patients who hadn't gotten a mutation, hadn't switched, and were still okay. So screening everybody is the big question, and when you would start and who you would change on and how this affects outcome. Patients didn't have access to camizestrant in the control arm, something we can't fix but we have experimental drugs. We're actually planning a trial, I hope in collaboration with the French group Unicancer, and looking at this exact question. You know, if you switch and you change the CDK4/6 inhibitor and then you also allow crossover, what will we see? Dr. Monty Pal: We're coming right to the tail end of our time here, and I could probably go on for another couple of hours with you here. But if you could just give us maybe one or two big highlights from San Antonio, any thoughts to leave our audience with here based on this recent meeting? Dr. Hope Rugo: Yeah, I mean, I talked about a lot of those new data already from San Antonio, and the one that I'd really like to mention which I think was, you know, there were a lot of great presentations including personalized screening presented from the WISDOM trial by my colleague Laura Esserman, fascinating and really a big advance. But lidERA was the big highlight, I think, outside of the HER2CLIMB-05 which I talked about earlier in HER2-positive disease. And this study looked at giredestrant, the oral SERD versus standard of care endocrine therapy as treatment for medium and high-risk early-stage breast cancer. And what they showed, which I think was really remarkable with just about a three-year median follow-up, was an improvement in invasive disease-free survival with a hazard ratio of 0.7. I mean, really quite remarkable and so early. It looked as though this was all driven by the high-risk group, which makes sense, not the medium risk, it's too early. And also that there was a bigger benefit in patients who were on tamoxifen compared to giredestrant versus AI, but for both groups, the confidence intervals didn't cross 1. There's even a trend towards overall survival, even though it's way too early. I think that, you know, really well-tolerated oral drug that could improve outcome in early-stage disease, this is the first advance we've seen in over two decades in the treatment of early-stage hormone receptor-positive disease with just endocrine therapy. I think we think that we don't want to give up CDK4/6 inhibitors because we saw a survival benefit with abemaciclib and a trend with giving ribociclib in the NATALEE trial. So we're thinking that maybe one approach would be to give CDK4/6 inhibitors and then switch to an oral SERD or to have enough data to be able to give oral SERDs with these CDK4/6 inhibitors for early-stage disease. And that's all in the works, you know, lots of studies going on. We're going to see a lot of data with both switching 8,000 patients with an imlunestrant switching trial, an elacestrant trial going on, and safety data with giredestrant with abemaciclib and soon to come ribociclib. So, this is going to change everything for the treatment of early-stage breast cancer, and I hope cure more patients of the most common subset of the most common cancer diagnosed in women worldwide.
