Host Dr. Shannon Westin and guest Dr. Hani Babiker discuss the JCO article "Tumor Treating Fields With Gemcitabine and Nab-Paclitaxel for Locally Advanced Pancreatic Adenocarcinoma: Randomized, Open-Label, Pivotal Phase III PANOVA-3 Study." TRANSCRIPT TTFields in Locally Advanced Pancreatic Adenocarcinoma Dr. Shannon Westin: Hello everyone, and welcome to another episode of JCO After Hours, the podcast where we get in depth with manuscripts that have been published in the Journal of Clinical Oncology. I am your host, gynecologic oncologist Shannon Westin, social media editor at the JCO, and just excited to be here to learn today about pancreatic cancer. None of our participants have conflicts of interest related to this podcast, and it is my honor to introduce Dr. Hani Babiker. He is an associate professor of medicine, consultant in oncology at the Mayo Clinic in Jacksonville, Florida. Welcome, Dr. Babiker. Dr. Hani Babiker: Hi, Dr. Westin. Thank you for the great opportunity to discuss our trial, and thank you for having me here. I really appreciate it, and I am excited. Dr. Shannon Westin: All right, so are we. So we are going to be talking about “Tumor Treating Fields with Gemcitabine and Nab-Paclitaxel for Locally Advanced Pancreatic Adenocarcinoma: A Randomized, Open-Label, Pivotal Phase III PANOVA-3 Study.” This was simultaneously published and presented in the JCO and at the annual meeting of ASCO on 5/31/2025. So, let's level set. Can you speak to us just a little bit about pancreatic cancer? What is the survival, and what is the typical treatment for locally advanced disease? This gynecologic oncologist has not kept up in this field. Dr. Hani Babiker: Absolutely, Dr. Westin, and thank you for that question. Pancreatic adenocarcinoma is a lethal cancer. When I first started my career, the 5-year survival, per the Surveillance, Epidemiology, and End Results, was at 4.5%. I always, whenever I was giving talks, say that I really hope that I will see it in the double digit. Now, the 5-year survival for all pancreatic adenocarcinoma is 13.3%. And the 5-year survival, and although it is a double digit, I still hope that I will see it in a higher double digit in the future. It is even worse in patients with metastatic cancer, about 3% 5-year survival for metastatic pancreatic cancer. It is a dismal diagnosis. I really hope in the future we will find a better therapeutic approach to this lethal cancer. Dr. Shannon Westin: Yes, I just lost a very dear friend and colleague to this disease, so I completely agree with you. Well, now that we are settled kind of with the basics here, I would love to talk a little bit about kind of the primary piece of this intervention, the Tumor Treating Fields. So, how does this work? And what diseases has it gotten indications in as yet? Dr. Hani Babiker: Absolutely. So, Tumor Treating Fields is alternating frequency electrical fields that have been studied preclinically and shown that it abrogates cancer cell proliferation. Earlier on, we knew that it inhibits polymerization of tubulin, and hence, it affects cancer cells from proliferating. Later, we are learning that there are multiple mechanisms of action. It affects permeability, allowing for better drug delivery. It also inhibits cancer cell proliferation through affecting autophagy mechanisms that pancreatic cancer cells will use for proliferating and becoming more aggressive. There is also some early data preclinically in colorectal cancer cell lines and lung cancer cell lines and in vivo models showing that it potentially could activate the microenvironment to make it more pro-immunogenic. We recently published papers showing that it could also affect the nanomechanical properties of the tumor microenvironment within pancreatic cancer, hinting towards affecting, potentially, the stroma. So, there are multiple mechanisms to Tumor Treating Electric Fields. It is a new, novel therapeutic approach. Sometimes when I speak with my trainees, I say, "Well, we have surgery, we have radiation and chemotherapy, and this is something new." Tumor Treating Fields initially was studied in refractory GBM and got an indication there. Subsequently, frontline treatment of GBM in a randomized clinical trial, and then malignant pleural mesothelioma and non-small cell lung cancer. We have studied it in pancreatic cancer. Dr. Shannon Westin: I don't think I have ever heard it described so perfectly. That was brilliant. So thank you, and I hope everyone listening knows that you just got a masterclass on this mechanism. You know, they dabbled in it a little bit in ovarian cancer and it didn't quite make the grade, so I was a little definitely disappointed. But very excited about the data we're going to talk about today. So let's get into the PANOVA-3 study. Can you highlight the overall design and also the key eligibility criteria that would be helpful for our listeners? Dr. Hani Babiker: Absolutely. So, it started off with preclinical work in pancreatic cancer showing Tumor Treating Fields with chemo abrogate cancer cell perforation. It led to a trial, the PANOVA-2 trial, that was run in Europe that showed efficacy for OS and PFS in patients with locally advanced pancreatic cancer, which included metastatic and locally advanced pancreatic cancer, more so in locally advanced that led to the PANOVA-3 trial, which was an international, global study. This was in more than 190 centers, 20 countries in Latin America, North America, Europe, and Asia. It was a randomized trial. Patients were randomized 1 to 1 to either chemotherapy with gemcitabine plus nab-paclitaxel per drug label. The other arm was with Tumor Treating Fields at 150 kHz for a recommendation for patients to wear it 18 hours per day. The primary end point of the trial was OS, overall survival. The secondary end point included other efficacy landmarks such as local PFS, pain control, quality of life, and safety. And there was a post hoc that looked at distant PFS. Dr. Shannon Westin: That's a pretty common secondary end point in pancreatic studies of looking at the pain-free interval. I thought that was really brilliant because, you know, I think in gyn cancers, we see resolution of symptoms as being a really big deal, but it's not necessarily something that we always look at. So I thought that was really nice that you included that. Okay, talk to us a little bit about the population. So, the population that actually got treated in PANOVA-3 is pretty generalizable to what people are treating in the clinic. Dr. Hani Babiker: So, in pancreatic cancer, unfortunately, most of our patients present, approximately 80%, with metastatic disease. Local is divided to resectable, borderline, and locally advanced. We studied this trial, a randomized trial, in locally advanced and unresectable, which is really an unmet need. Most of our patients with locally advanced and unresectable are grouped up with other trials in the metastatic setting without a focus on locally advanced and unresectable, save for a few trials. This year, a trial that we were looking for for a long time, the LAPLACE trial, unfortunately, that we were very excited about, this is a molecule that targeted connective tissue growth factor, that showed earlier efficacy in a randomized trial, did not meet up the median OS end point. And hence, PANOVA-3 is the first trial in locally advanced and unresectable that did meet its primary end point. So, it's a very unmet need in locally advanced and unresectable. A lot of the times, our patients in clinic are treated with frontline chemotherapy that was studied in metastatic disease and locally advanced and unresectable, which include either FOLFIRINOX, NALIRIFOX, or gemcitabine/abraxane. I do have in my clinic multiple patients that would stay on the regimen for such a long time, and then we would have to devise a mechanism of maintenance, although this is not studied really in details, either with capecitabine or dropping the oxaliplatin to continue FOLFIRI. And then we also approach chemoradiotherapy. So the trial was in a disease in pancreatic cancer that really is an unmet need. So the inclusion criteria included a patient with locally advanced and unresectable. These were done at multiple centers. Most of them academic centers were discussed at the tumor board, and if it's unresectable, they will be meeting specific metrics of appropriate liver function tests, kidney function tests, and blood counts. We excluded patients that obviously had, given that these are electric fields, patients that have, for example, stimulators or pacemakers, knowing that this could potentially affect some of these devices. But for the most part, it was locally advanced and unresectable patients with a very good performance status and good counts. Dr. Shannon Westin: That's great. I think everyone's excited to hear about the primary outcome of overall survival. What did you find, and how does it compare to some of the recent trials? Dr. Hani Babiker: We're very excited that it did meet its primary end point of median overall survival. It was very exciting knowing that a lot of us were disappointed a little bit of some of the trials that were presented at ASCO GI, such as the LAPLACE trial that I alluded to. Just before the presentation, the PRODIGE 29 trial that is in locally advanced and unresectable that randomized patients with locally advanced disease to either FOLFIRINOX or single-agent gemcitabine, allowing for a crossover, although it did meet its primary end point of PFS, there was no overall survival benefit. So that kind of got us a little bit disappointed, but having the PANOVA-3 trial being positive in median OS got us all excited. In addition, the 12-year overall survival rate was increased in both the intention-to-treat and modified intention-to-treat. The modified intention-to-treat were patients that have had at least one cycle of therapy with TTFields daily and
JCO fellow Dr. Ece Cali speaks with JCO Associate Editor Dr. Thomas E. Stinchcombe to discuss the JCO article "Phase 2 Dose-Randomized Study of Sunvozertinib in Platinum-Pretreated Non-Small-Cell Lung Cancer with Epidermal Growth Factor Receptor Exon 20 Insertion Mutations (WU-KONG1B)", that was simultaneously released at the IASLC 2025 World Conference on Lung Cancer. TRANSCRIPT Dr. Ece Cali: Hello, and welcome to our series where we cover some of the top JCO papers published simultaneously with their abstract presentation at this year’s most important oncology meetings. I am your host, Dr. Ece Cali, JCO editorial fellow, and I am joined by Dr. Tom Stinchcombe, JCO associate editor, to discuss the Journal of Clinical Oncology article and 2025 World Conference on Lung Cancer abstract presentation, “Phase II Dose-Randomized Study of Sunvozertinib in Platinum-Pretreated Non–Small Cell Lung Cancer With EGFR Exon 20 Insertion Mutations.” The WU-KONG1B trial is a multinational, phase II study that investigated the efficacy and safety of different doses of sunvozertinib in patients with metastatic non-small cell lung cancer and EGFR exon 20 insertion mutations after progression on platinum based chemotherapy. Tom, before we dive into the results, could you walk us through the rationale for this study, and how does it fit into the current treatment options for patients with EGFR exon 20 insertion? Dr. Tom Stinchcombe: Thank you, Dr. Cali. I think the clinical context is always important. We have known that EGFR exon 20 insertions exist and that they are resistant to our currently available EGFR tyrosine kinase inhibitors, and I think there have been attempts in the past to develop a tyrosine kinase inhibitor, but there is a very narrow therapeutic window between the dose you need to inhibit the EGFR mutation in the cancer and the EGFR receptor on normal tissues, most notably the mucosa, the gut, and the skin. And so, our previous attempts have failed largely because the dose required was not tolerable for patients and they could not really stay on the drug for a long time or they were not very active. And so, I think there was a real desire to develop an EGFR tyrosine kinase inhibitor, and then, historically, the standard had been a platinum based doublet as the standard of care. And more recently, platinum based doublet with amivantamab has proven to be superior to platinum based chemotherapy alone. I think the context is also important that amivantamab is not necessarily available in all the countries, and so, there are patients who do not have access to amivantamab. Going to the rationale, I think that this drug had shown preliminary promise of having activity but without that being encumbered by those EGFR wild type toxicities, and, therefore, it was really explored in this larger study. Dr. Ece Cali: And what are some key findings from this trial? Dr. Tom Stinchcombe: So, I think that we should look at the study design. It is a little quirky, for lack of a better term, in that there is a randomization to 200 versus 300 mg, and then, there was a nonrandomized cohort of 300 mg. So, when you look at the study, if you are a purist, you will just look at the randomized patients. If you are sort of an aggregator, you look at all patients. So, it shows reporting on three cohorts, but I think the key findings are that the 200 mg and the 300 mg treatments had similar toxicities in terms of response rate, duration of response, and progression free survival. And as you know going through the review, there was a lot of queries from the reviewers as to which would be the preferred dose, and to me, I think this really illustrates a dose finding component to a trial design because there is a lot of debate about what the minimal effective dose is or the optimal dose. And in this case, having the two dose cohorts did provide us some valuable efficacy and toxicity information. And then, when I look at the study, I want to make sure it reflects my patient population, and about a quarter of patients had brain metastases, and about 15% had previous amivantamab, and about 5% to 10% had another EGFR tyrosine kinase inhibitor. Dr. Ece Cali: And what is the objective response rate and the duration of response? These are pretty good numbers for this patient population. Dr. Tom Stinchcombe: In the 200 mg cohort, it was about 46%. The duration of response was around 11 months, and the PFS was around 8 months. The 300 mg cohort was 46%, duration of response 9.8, and the median PFS is 6.9 months, and I think that this is greater activity than we have seen with our previous attempts at EGFR tyrosine kinase inhibitors. Dr. Ece Cali: And based on these data, FDA granted accelerated approval for sunvozertinib very recently at 200 mg once daily dosing in this setting. So, that is a major step forward for our patients. Dr. Stinchcombe, how does this impact your clinical practice, and what side effects should oncologists be watching for if they prescribe this medication? Dr. Tom Stinchcombe: So, I think it was very interesting that they chose the 200 mg dose, which I think was more tolerable, and when we kind of look at this, there still was a rate of diarrhea, all grade, rash, paronychia, which are the EGFR related toxicities. There can be some decreased appetite, stomatitis, and then, it can lead to some lab abnormalities, like increased CPK and creatinine that physicians have to be aware of. You know, how it will affect my practice is that all these patients had received a platinum based chemotherapy as the first line therapy. I think that this would become my preferred second line therapy for patients outside the context of a trial because of the activity and the tolerability. Dr. Ece Cali: And lastly, several other tyrosine kinase inhibitors are being evaluated for EGFR exon 20 insertion, including in the frontline setting. So, what are some of the outstanding questions in this space, and what data should our listeners keep an eye on moving forward? Dr. Tom Stinchcombe: I think you are right that now, there is going to be another EGFR tyrosine kinase that may become available in the next year, and there is another drug, furmonertinib, that is being investigated. I think, for the clinical question, is, well, can we move these into the first line setting? And actually, the development path has two ways of doing this. There is EGFR tyrosine kinase compared to platinum based chemotherapy, and then, platinum based chemotherapy with an EGFR tyrosine kinase versus platinum based chemotherapy, and both have their merits and strengths. And so, I think it is going to be very interesting as we see if those first line trials, one, can they be demonstrated to be superior to platinum based chemotherapy, and then by what magnitude and what the side effects are. But I think we are hoping that in the next couple of years, we will have an additional first line option for our patients. Dr. Ece Cali: Yeah, it is always great to have more options for our patients.

Host Davide Soldato and guest Dr. John K. Lin discuss the JCO article "Racial and Ethnic Disparities Along the Treatment Cascade Among Medicare Fee-For-Service Beneficiaries with Metastatic Breast, Colorectal, Lung, and Prostate Cancer." TRANSCRIPT The guest on this podcast episode has no disclosures to declare. Dr. Davide Soldato: Hello, and welcome to JCO After Hours, the podcast where we sit down with authors of the latest articles published in the Journal of Clinical Oncology. I'm your host, Dr. Davide Soldato, a medical oncologist at Ospedale San Martino in Genoa, Italy. Today, we are joined by Dr. Lin, assistant professor in the Department of Health Services Research at the University of Texas MD Anderson Cancer Center. Dr. Lin and I will be discussing the article titled, "Racial and Ethnic Disparities Along the Treatment Cascade Among Medicare Fee-for-Service Beneficiaries With Metastatic Breast, Colorectal, Lung, and Prostate Cancer." Thank you for speaking with us, Dr. Lin. Dr. Lin: Thank you so much for having me. I appreciate it. Dr. Davide Soldato: So, just to start, to frame a little bit the study, I just wanted to ask you what prompted you and your team to look specifically at this question - so, racial and ethnic disparities within this specific population? And related to this question, I just wanted to ask how this work is different or builds on previous work that has been done on this research topic. Dr. Lin: Yeah, absolutely. Part of the impetus for this study was the observation that despite people who are black or Hispanic having equivalent health insurance status - they all have Medicare Fee-for-Service - we've known that treatment and survival differences and disparities have persisted over time for patients with metastatic breast, colorectal, lung, and prostate cancer. And so, the question that we had was, "Why is this happening, and what can we do about it?" One of the reasons why eliminating racial and ethnic disparities in survival among Medicare beneficiaries with metastatic cancer has been elusive is because these disparities are occurring along a lot of dimensions. Whether or not it's because the patient presented late and has very extensive metastatic cancer; whether or not the patient has had a difficult time even seeing an oncologist; whether or not the patient has had a difficult time starting on any systemic therapy; or maybe it's because the patient has had a difficult time getting guideline-concordant systemic therapy because, more recently, these treatments have become so expensive. Disparities, we know, are occurring along all of these different facets and areas of the treatment cascade. Understanding which one of these is the most important is the key to helping us alleviate these disparities. And so, one of our goals was to evaluate disparities along the entire treatment cascade to try to identify which disparities are most important. Dr. Davide Soldato: Thank you very much. That was very clear. So, basically, one of the most important parts of the research that you have performed is really focusing on the entire treatment cascade. So, basically, starting from the moment of diagnosis up to the moment where there was the first line of treatment, if this line of treatment was given to the patient. So, I was wondering a little bit, because for this type of analysis, you used the SEER-Medicare linked database. So, can you tell us a little bit which was the period of time that you selected for the analysis? Why do you think that that was the most appropriate time to look at this specific question? And whether you feel like there is any potential limitation in using this type of database and how you handled this type of limitations? Dr. Lin: Yeah, absolutely. It's a great question. And I want to back up a little bit because I want to talk about the entire treatment cascade because I think that this is really important for our research and for future research. We weren't the first people to look at along the treatment cascade for a disease. Actually, this idea of looking along the treatment cascade was pioneered by HIV researchers and has been used for over a decade by people who study HIV. And there are a lot of parallels between HIV and cancer. One of them is that with HIV, there are so many areas along that entire treatment cascade that have to go right for somebody's treatment to go well. Patients have to be diagnosed early, they have to be given the right type of antiretrovirals, they have to be adherent to those antiretrovirals. And if you have a breakdown in any one of those areas, you're going to have disparities in care for these HIV patients. And so, HIV researchers have known this for a long time, and this has been a big cornerstone in the success of getting people with HIV the treatment that they need. And I think that this has a lot of parallels with cancer as well. And so, I am hoping that this study can serve as a model for future research to look along the entire treatment cascade for cancer because cancer is, similarly, one of these areas that requires multidisciplinary, complex medical care. And understanding where it is breaking down, I think, is crucial to us figuring out how we can reduce disparities. But for your question about the SEER-Medicare linked database, so we looked between 2016 and 2019. That was the most recent data that was available to us. And one of the reasons why we were excited to look at this is because there were some new treatments that were just released and FDA-approved around 2018, which we were able to study. And this included immunotherapy for non–small cell lung cancer, and then it also included androgen receptor pathway inhibitors, the second-generation ones, for prostate cancer. And the reason why this is important is because for some time, as we have developed these new therapies, there's been a lot of concern that there have been disparities in access to these novel therapies because of how expensive they are, particularly for the Medicare population. And so one of the reasons why we looked specifically at this time period was to understand whether or not, in more recent years, these novel therapies, people are having increasing disparities in them and whether or not increasing disparities in these more expensive, newer therapies is contributing to disparities in mortality. That being said, obviously, we're in 2025 and these data are by now six years old, and so there are additional therapies that are now available that weren't available in the past. But I think that, that being said, at least it's sort of a starting point for some of the more important therapies that have been introduced, at least for non–small cell lung cancer and prostate cancer. And the database, SEER-Medicare, is helpful because it uses the population cancer registry, which is the SEER registry cancer registry, linked to Medicare claims. So, any type of medical care that's billed through Medicare, which is going to basically be all of the medical care that these patients receive, for the most part, we're going to be able to see it. And so, I think that this is a really powerful database which has been used in a lot of research to understand what kind of care is being received that has been billed through Medicare. So, one of the limitations with this database is if there is care that's received that was not billed through Medicare, we're not going to be able to see that. And this does not happen probably that frequently, particularly because most patients who have insurance are going to be receiving care through insurance. However, we may see it for some of the oral Part D drugs. Some of those drugs are so expensive that patients cannot pay for the coinsurance during that time. And it's possible that some of those drugs patients were getting for free through the manufacturer. We potentially missed some of that. Dr. Davide Soldato: So, going a little bit into the results, I think that these are very, very interesting. And probably the most striking one is that when we look at the receipt of any type of treatment for metastatic breast, colorectal, prostate, and lung cancer - and specifically when we look at guideline-directed first-line treatments - you observed striking differences. So, I just wanted you to guide us a little bit through the results and tell us a little bit which of the numbers surprised you the most. Dr. Lin: So, what we were expecting is to see large disparities in receiving what we called guideline-directed systemic therapy. And guideline-directed systemic therapy during this time kind of depended on the cancer. So, we thought that we were going to see large disparities in guideline-directed therapy because these were the more novel therapies that were approved, and thus they were going to be the more expensive therapies. And so, what this meant was for colorectal cancer, this was going to be any 5-FU–based therapy. For lung cancer, this was going to be any checkpoint inhibitor–based therapy. For prostate cancer, this was going to be any ARPI, so this was going to be things like abiraterone or enzalutamide. And for breast cancer, this was going to be CDK4 and 6 TKIs plus any aromatase inhibitor. And so, for instance, for breast, prostate, and lung cancer, these were going to be including more expensive therapies. And so, what we expected to see was large disparities in receiving some of these more expensive, novel therapies. And we thought we were going to see fewer disparities in receiving some of the cheaper therapies, such as aromatase inhibitors, 5-FU, older platinum chemotherapies for lung cancer, and ADT for prostate cancer. We were shocked to find that we saw large racial and ethnic disparities in seeing some of the older, cheaper chemotherapies and hormonal therapies. So for instance, for breast cancer, 59% of black patients received systemic therapy, whereas 68% of white patients received systemic t
In this JCO Article Insights episode, Dr. Joseph Matthew interviews authors Dr. Yang Zhang and Dr. Haiquan Chen about their recently published JCO article, "Phase III Study of Mediastinal Lymph Node Dissection for Ground Glass Opacity–Dominant Lung Adenocarcinoma" TRANSCRIPT Joseph Mathew: Welcome to the Journal of Clinical Oncology Article Insights episode for the August issue of the JCO. This is Joseph Mathew, editorial fellow for JCO, and today, it is my pleasure to have with us Dr. Haiquan Chen and Dr. Yang Zhang, authors of the recently published manuscript, "Phase 3 Study of Mediastinal Lymph Node Dissection for Ground-Glass Opacity-Dominant Lung Adenocarcinoma," which we will be discussing today. Dr. Chen is the Director of the Institute of Thoracic Oncology at Fudan University and the Chief of Thoracic Surgery at Fudan University Shanghai Cancer Center, where he is also the Head of Thoracic Oncology MDT and the Director of the Lung Cancer Center. Dr. Chen is a surgeon-scientist and a pioneer in developing individualized surgical strategies for early-stage non-small cell lung cancer. Dr. Zhang is a surgical oncologist and a member of the team which Dr. Chen leads at the Fudan University Shanghai Cancer Center. Welcome Dr. Chen and Dr. Zhang. Thank you very much for accepting our invitation and joining us today as part of this podcast episode. To summarize the salient points, this study presented the interim analysis of a multi-center, open-label, non-inferiority, randomized controlled trial investigating the necessity of systematic mediastinal lymph node dissection at the time of segmentectomy or lobectomy in patients with clinical stage T1N0M0 ground-glass opacity-dominant invasive lung adenocarcinoma, as defined by a consolidation-to-tumor ratio of 0.5 or less on thin-section computed tomography and a maximum tumor diameter of 3 cm or less. Eligible participants with intraoperatively confirmed invasive adenocarcinoma on frozen section analysis were randomized to either the systematic mediastinal lymph node dissection arm or to no mediastinal lymph node dissection. In the latter experimental group, mediastinal lymph nodes comprising the N2 nodal stations were not dissected, and the hilar nodes were variably addressed at the discretion of the operating surgeon. The primary endpoint of the trial was disease-free survival at 3 years. Secondary endpoints included perioperative outcomes, the status of lymph node metastasis in the systemic lymph node dissection arm, and 3-year overall survival. Before the trial reached its accrual target, a pre-planned interim safety analysis set for the time point when enrollment reached 300 patients was performed. It was noted that while none of the patients in either arm had nodal metastasis on postoperative pathological evaluation, lymph node dissection-related intraoperative and postoperative complications were more commonly observed in the systematic lymph node dissection arm, including one life-threatening episode of massive bleeding. Since this met the predefined criteria for trial termination, and in accordance with the principle of non-maleficence, further recruitment was stopped and the trial terminated. Although the 3-year disease-free survival and the overall survival for the enrolled patients were comparable, operative outcomes, including the duration of surgery, blood loss, chest tube duration, length of postoperative stay, and the rate of clinically significant complications, were significantly lower in the experimental arm compared with the systematic lymph node dissection group. The authors concluded that for well-selected patients, mediastinal nodal dissection could be omitted without adversely affecting oncological outcomes, representing a significant shift in current surgical practice, given that guidelines the world over recommend systematic lymph node dissection or sampling for all invasive lung cancers. In summary, this study addressed a clinically relevant question with regard to the extent of nodal dissection, especially in the light of recent evidence recommending less extensive parenchymal dissections for early-stage non-small cell lung cancer, with the findings suggesting that invasive lung adenocarcinoma associated with ground-glass opacities of consolidation-to-tumor ratio up to 0.5 was an excellent predictor of tumor biology, and in clinical T1N0M0 lesions, a reliable predictor of negative mediastinal lymph node involvement. So Dr. Chen and Dr. Zhang, could you tell us some more about what led you to do this research and the challenges which you faced while recruiting patients for this trial? Dr. Yang Zhang: Dr. Mathew, thank you for your summary. The current clinical guidelines recommend systematic lymph node dissection or sampling for every patient with early-stage lung cancer, regardless of their lymph node status. And in our clinical practice, we observe that this procedure causes a lot of surgical complications including chylothorax and recurrent laryngeal nerve injury. Furthermore, dissecting the tumor-draining lymph nodes actually may potentially damage the body's anti-tumor immunity. So, Dr. Chen proposed the concept of selective lymph node dissection, which we aimed to dissect the metastatic lymph nodes, while at the same time we try to preserve as many uninvolved lymph nodes as possible. So previously, we have conducted a series of retrospective studies to identify reliable predictors of nodal negative status in certain mediastinal zones, and we have performed a prospective observational phase 2 clinical trial to validate that the six criteria we proposed are 100% in predicting node-negative status. And this forms the basis for our phase 3 clinical trial. Dr. Haiquan Chen: This trial is only one of the series of trials. The meaning of this trial you already said. And for a long time, from the surgeon's point of view, we considered minimally invasive surgery. It minimizes the size of the incision and minimizes the number of the holes we made. So, the true and the high-impact of minimally invasive, we make a concept of minimal dissection, that means organ-level minimally invasive. So we proposed the concept of minimally invasive 3.0, that means minimal incision, minimal dissection (that means organ-level minimal), and systemic minimally invasive. So at first, we judged from the point of minimally invasive surgery. As long as immunotherapy is widely used in the clinical practice, we know immunotherapy, that means you use drugs to stimulate and activate the lymph node site. If we dissect all the metastatic lymph nodes, cut them out, how can we restimulate that lymph node site? So, from minimally invasive trauma and second, from the functional aspect, to try to save as many uninvolved lymph nodes as possible. Joseph Mathew: Thank you, Dr. Chen. That's a very interesting concept that you alluded to even in the discussion of this paper, as to the potential role of the non-metastatic lymph nodes as immune reservoirs. So, coming back to this paper, were there any challenges which you faced while recruiting patients for this trial? Dr. Haiquan Chen: The criteria is very clear. That means invasive adenocarcinoma, that means most of the centimeter is 3.0 centimeter and also CTR ratio less than 0.5. And we can see that, you know, we did study about that. Even the invasive component of the subsolid nodule, it's bigger than the solid part. That means even the pure GGO, we can find out that there's still some invasive component. From this point of view, pure GGO and subsolid GGO, from this part of invasive carcinoma, that means it's a special clinical subtype that we, from retrospective study and also prospective study, we find out this group of patients, there are no mediastinal lymph node metastasis. So I think it's very important for this kind of group that we can avoid doing the mediastinal lymph node dissection. And we can do organ-level minimally invasive surgery. And also, we try to keep the patient's immune function as normal as possible. Dr. Yang Zhang: Well, Dr. Mathew, we believe that the biggest challenge when we are enrolling these patients is that there needs to be a paradigm shift in the mind because systematic lymph node dissection has long been the standard of care. And some patients may misunderstand. Before the enrollment, we have to give them informed consent, but if the patient hears that they may be enrolled in the no-lymph-node-dissection group, they may feel that they do not receive radical, curative-intent surgery. So we believe, as Dr. Chen has said, after the release of our results, the no-lymph-node dissection may be incorporated in the future guideline for those patients without lymph node involvement, we can just omit the lymph node dissection. Joseph Mathew: The study described two pre-planned interim points during the course of subject enrollment when the data was analyzed. So Dr. Chen and Dr. Zhang, could you please explain a little more about these two interim points of analysis that were planned and the rationale behind it? Dr. Yang Zhang: When conducting this trial, we have two concerns. One is if there is any lymph node metastasis, there may be omission of metastatic lymph nodes not dissected in the no-lymph-node-dissection group. And there is another concern is that if all these lymph nodes are uninvolved, then dissecting these lymph nodes may cause life-threatening complications. So, we set the 150 interim analysis to ensure that there is no lymph node involvement in this group. And the other early termination criteria is set because if there is no lymph node involvement found in both groups, then a severe complication which is life-threatening is unacceptable because it threatens the patient's safety. Joseph Mathew: So, although you did briefly allude to in the paper, what was the basis for selecting DFS as the primary endpoint when the objective of this trial was to assess nodal involvement
In this JCO Article Insights episode, Michael Hughes summarizes “International Myeloma Society and International Myeloma Working Group Consensus Recommendations on the Definition of High-Risk Multiple Myeloma" by Avet-Loiseau et al. published on June 09, 2025 along with an interview with author Dr Nikhil C. Munshi, MD. TRANSCRIPT Michael Hughes: Welcome to this episode of JCO Article Insights. This is Michael Hughes, JCO’s editorial fellow. Today I am interviewing Dr. Nikhil Munshi on the “International Myeloma Society and International Myeloma Working Group Consensus Recommendations on the Definition of High-Risk Multiple Myeloma” by Avet-Loiseau et al. At the time of this recording, our guest has disclosures that will be linked in the transcript. While some patients with multiple myeloma live for decades after treatment, others exhibit refractory or rapidly relapsing disease irrespective of treatment administered. We term this “high-risk myeloma.” Multiple risk stratification systems have been created, starting with the Durie-Salmon system in 1975 and evolving with the advent of novel therapeutics and novel treatment approaches. In 2015, the Revised International Staging System (R-ISS) was introduced, which incorporated novel clinical and cytogenetic markers and remained, until recently, a mainstay of risk stratification in newly diagnosed disease. Myeloma as a field has, just in the past few years, though, undergone explosive changes. In particular, we have seen groundbreaking advances not only in treatments - the introduction of anti-CD38 agents and the advent of cellular and bispecific therapies - but also in diagnostic technology and our understanding of the genetic lesions in myeloma. This has led to the proliferation of numerous trials employing different definitions of high-risk myeloma, a burgeoning problem for patients and providers alike, and has prompted attempts to consolidate definitions and terminology. Regarding cytogenetic lesions, at least, Kaiser et al’s federated meta-analysis of 24 therapeutic trials, published here in the JCO in February of 2025 and recently podcasted in an interview with associate editor Dr. Suzanne Lentzsch, posited a new cytogenetic classification system to realize a shared platform upon which we might contextualize those trial results. This article we have here by Dr. Avet-Loiseau, Dr. Munshi, and colleagues, published online in early June of this year and hot off the presses, is the definitive joint statement from the International Myeloma Society (IMS) and the International Myeloma Working Group (IMWG). What is high-risk multiple myeloma for the modern era? The IMS and IMWG Genomics Workshop was held in July 2023 and was attended by international myeloma experts, collaborating to reach consensus based on large volumes of data presented and shared. The datasets included cohorts from the Intergroupe Francophone du Myélome (IFM); the HARMONY project, comprised of multiple European academic trials; the FORTE study, findings from which solidified KRd as a viable induction regimen; the Grupo Español de Mieloma Múltiple (GEM) and the PETHEMA Foundation; the German-Speaking Myeloma Multicenter Group (GMMG); the UK-based Myeloma XI, findings from which confirmed the concept of lenalidomide maintenance; Emory 1000, a large, real-world dataset from Emory University in Atlanta; the Multiple Myeloma Research Foundation Clinical Outcomes in Multiple Myeloma to Personal Assessment of Genetic Profile (CoMMpass) dataset; and some newly diagnosed myeloma cohorts from the Mayo Clinic. Data were not pooled for analyses and were assessed individually - that is to say, with clear a priori understanding of whence the data had been gathered and for what original purposes. Consensus on topics was developed based on the preponderance of data across studies and cohorts. In terms of results, substantial revisions were made to the genomic staging of high-risk multiple myeloma, and these can be sorted into three major categories: A) alterations to the tumor suppressor gene TP53; B) translocations involving chromosome 14: t(14;16) (c-MAF overexpression), t(14;20) (MAFB overexpression), and t(4;14) (NSD2 overexpression); and C) chromosome 1 abnormalities: deletions of 1p or additional copies of 1q. In terms of category A, TP53 alterations: Deletion of 17p is present in up to 10% of patients at diagnosis and is enriched in relapsed or refractory disease. This is well-documented as a high-risk feature, but the proportion of the myeloma cells with deletion 17p actually impacts prognosis. GEM and HARMONY data analyses confirmed the use of 20% clonal cell fraction as the optimal threshold value for high-risk disease. That is to say, there must be the deletion of 17p in at least 20% of the myeloma cells on a FISH-analysis of a CD138-enriched bone marrow sample to qualify as high-risk disease. TP53 mutations can also occur. Inactivating mutations appear to have deleterious effects similar to chromosomal losses, and the biallelic loss of TP53, however it occurs, portends particularly poor prognosis. This effect is seen across Myeloma XI, CoMMpass, and IFM cohorts. Biallelic loss is rare, it appears to occur in only about 5% of patients, but next-generation sequencing is nevertheless recommended in all myeloma patients. Category B, chromosome 14 translocations: Translocation t(14;16) occurs in about 2% to 3% of patients with newly diagnosed disease. In the available data, primarily real-world IFM data, t(14;16) almost always occurs with chromosome 1 abnormalities. Translocation t(4;14) occurs in about 10% to 12% of newly diagnosed disease, but only patients with specific NSD2 alterations are, in fact, at risk of worse prognosis, which clinically appears to be about one in every three of those patients. And so together, the CoMMpass and Myeloma XI data suggest that translocation t(4;14) only in combination with deletion 1p or gain or amplification of 1q correlates with worse prognosis. Translocation t(14;20) occurs in only 2% of newly diagnosed disease. Similar to translocation t(4;14), it doesn’t appear to have an effect on prognosis, except if the translocation co-occurs with chromosome 1 lesions, in which case patients do fare worse. Overall, these three translocations - t(14;16), t(4;14), and t(14;20) - should be considered high-risk only if chromosome 1 aberrations are also present. In terms of those chromosome 1 aberrations, category C, first deletions of 1p: Occurring in about 13% to 15% of newly diagnosed disease, deletion 1p eliminates critical cell checkpoints and normal apoptotic signaling. In the IFM and CoMMpass dataset analyses, biallelic deletion of 1p and monoallelic deletion of 1p co-occurring with additional copies of 1q denote high-risk. In terms of the other aberration in chromosome 1 possible in myeloma, gain or amplification of 1q: This occurs in up to 35% to 37% of newly diagnosed disease. It upregulates CKS1B, which is a cyclin-dependent kinase, and ANP32E, a histone acetyltransferase inhibitor. GEM and IFM data suggest that gain or amplification of 1q - there was no clear survival detriment to amplification - is best considered as a high-risk feature only in combination with the other risk factors as above. Now, in terms of any other criteria for high-risk disease, there remains one other item, and that has to do with tumor burden. There has been a consensus shift, really, in both the IMS and IMWG to attempt to develop a definition of high-risk disease which is based on biologic features rather than empirically observed and potentially temporally dynamic features, such as lactate dehydrogenase. Beta-2 microglobulin remains an independent high-risk indicator, but care must be taken when measuring it, as renal dysfunction can artificially inflate peripheral titers. The consensus conclusion was that a beta-2 microglobulin of at least 5.5 without renal failure should be considered high-risk but should not preclude detailed genomic profiling. So, in conclusion, the novel 2025 IMS-IMWG risk stratification system for myeloma is binary. It’s either high-risk disease or standard-risk disease. It’s got four criteria. Number one, deletion 17p and/or a TP53 mutation. Clonal cell fraction cut-off, remember, is 20%. Or number two, an IGH translocation - t(4;14), t(14;16), t(14;20) - with 1q gain and/or deletion of 1p. Or a monoallelic deletion of 1p with 1q additional copies or a biallelic deletion of 1p. Or a beta-2 microglobulin of at least 5.5 only when the creatinine is normal. This is a field-defining work that draws on analyses from across the world to put forward a dominant definition of high-risk disease and introduces a new era of biologically informed risk assessment in myeloma. Now, how does this change our clinical approach? FISH must be performed on CD138-enriched samples and should be performed for all patients. Next-generation sequencing should also be performed on all patients. Trials will hopefully now begin to include this novel definition of high-risk multiple myeloma. It does remain to be seen how data from novel therapeutic trials, if stratified according to this novel definition, will be interpreted. Will we find that therapies being evaluated at present have differential effects on myelomas with different genetic lesions? Other unanswered questions also exist. How do we go about integrating this into academic and then community clinical practice? How do we devise public health interventions for low-resource settings? To discuss this piece further, we welcome the esteemed Dr. Nikhil Munshi to the podcast. Dr. Munshi is a world-renowned leader in multiple myeloma and the corresponding author on this paper. As Professor of Medicine at Harvard Medical School, Director of the Multiple Myeloma Effector Cell Therapy Unit, and Director of Basic and Correlative Science at the Jerome Lipper Multiple Myeloma Center of the Dana-Farber Cancer Institute, he has presided over critical
In this JCO Article Insights episode, host Peter Li summarizes "Taletrectinib in ROS1-Mutated Non–Small Cell Lung Cancer: TRUST" by Pérol et al, published April 03, 2025, followed by an interview with first author, Dr Maurice Pérol. TRANSCRIPT The disclosures for guests on this podcast can be found in the show notes. Dr. Peter Li: Welcome to this episode of JCO Article Insights. I am Dr. Peter Li, JCO’s editorial fellow, and today I am joined by Dr. Maurice Pérol on “Taletrectinib in ROS1-Mutated Non–Small Cell Lung Cancer: TRUST,” by Pérol et al. At the time of this recording, our guest has disclosures that will be linked in the transcript. Before we start our interview, I want to give our listeners a quick summary of the TRUST study. For those tuning in, the TRUST study is a phase II, single-arm, open-label, nonrandomized, multicenter trial looking at the efficacy and safety of a novel, next-generation ROS1 TKI, taletrectinib, in advanced ROS1-mutated non–small cell lung cancer. While a relatively rare mutation, the prevalence of ROS1 mutations ranges from 0.9% to 2.6% of patients, with a third of patients presenting with brain mets at diagnosis.Current FDA-approved therapies include crizotinib, entrectinib, and repotrectinib, which have varying degrees of efficacy, in-coming with trade-offs in CNS penetrance and safety with newer generations, particularly in the realm of neurological side effects, highlighting an unmet need in this arena. A total of 273 patients with advanced non–small cell lung cancer with confirmed ROS1 mutation were recruited for this study. 160 patients were TKI-naive, while 113 were TKI-experienced with either crizotinib or entrectinib. Patients with asymptomatic brain mets were also allowed to enroll. In the TKI-naive arm, the median age was 57, with 91% of patients having stage IV disease, 20% having no more than one cycle of chemo, and 23% having brain mets at baseline. In the TKI-experienced arm, the median age was 53, with 97% having stage IV disease, 37% having received prior chemo, and about 50% having brain mets. Furthermore, about 10% of the study population had received entrectinib, while more than 90% had received crizotinib. About 10% had a known G2032R acquired resistance mutation. Taletrectinib was dosed at 600 mg daily until disease progression or unacceptable toxicities. The primary endpoint was overall response rate, with secondary endpoints being disease control rate, duration of response, time to response, and progression-free survival. For those with brain mets, intracranial overall response rate and disease control rate were also assessed. Median follow-up time was about 21 months in both cohorts. In the TKI-naive cohort, the overall response rate was 89%, with 8 patients achieving a complete response. Disease control rate was 95%, with a median duration of response of 44.2 months. Time to treatment response was about 1.5 months. Median progression-free survival was 45.6 months, with 52.6% not having progressed at 3 years. While overall survival data were immature, 66% of patients were still alive at 3 years. In the pretreated cohort, overall response rate was 56%, with 5 patients achieving a complete response. Overall response rate was 53% for those who were crizotinib-pretreated and 80% for the entrectinib-pretreated patients. Disease control rate was 88%, and median duration of response was about 16.5 months. Time to treatment response was also 1.5 months, and median progression-free survival was 9.7 months. Median overall survival was not reached, but 77.5% of patients were still alive at 1 year. Responses were consistently seen across subgroup analyses. 17 TKI-naive and 32 TKI-pretreated patients had measurable brain mets. In the TKI-naive arm, intracranial overall response rate was 77%. Disease control rate was 88%, and duration of response was 15 months. In the TKI-pretreated arm, intracranial overall response was 66%, with one patient achieving complete response. The disease control rate was 94%, and duration of response was about a year. For the 13 patients who had a known G2032R mutation, a 62% response rate was noted. Most common treatment-related side effects were AST/ALT elevation, nausea, and vomiting, with most being grade 1 or 2. Most common neurological side effects were dizziness, dysgeusia, and headache. Again, most were grade 1. QTc prolongation is another important adverse event to note, occurring in about 18% of all patients. Discontinuation rate from treatment was only 7%. There were three treatment-related deaths in this study: one from hepatic failure, one from pneumonia in the naive arm, and one from liver dysfunction in the pretreated arm. Dr. Peter Li: Maurice, thank you so much for joining us today to talk about your paper. Would you mind just giving yourself a brief introduction to the listeners out there of who you are? Dr. Maurice Pérol: So, my name is Maurice Perol. I'm a thoracic oncologist working in the Cancer Center of Lyon in France. And I'm involved in clinical research in thoracic oncology. I've been involved for many years now. Dr. Peter Li: Okay. And for listeners out there, don't forget, he's also the primary author of the paper that we just talked about. So, Maurice, let's begin. Can you tell our listeners what is the significance of your study? Dr. Maurice Pérol: Well, the results of these two large phase II studies - TRUST-I, which has been conducted in China, and TRUST-II, which was a global, worldwide phase II study - so, the results place taletrectinib as the TKI with the most favorable efficacy-tolerability ratio of the available ROS1-targeting TKIs, especially in frontline therapy. And this is based on the response rate, which was very impressive, the CNS penetration with a great CNS activity, the duration of response with a compelling 45 months median PFS in frontline setting. The level of activity in pretreated patients after crizotinib or entrectinib was also impressive and similar to that of repotrectinib, for example, but with a more favorable neurological tolerance profile. The toxicity is mainly represented with grade 1 or 2 transaminase elevation, but without clinical symptoms, and GI toxicity, but mainly grade 1 and 2. The neurological toxicity is low, especially for dizziness, showing that taletrectinib spares TrKB in a large part. And finally, there is also a decrease in toxicity over time, especially for GI toxicity and liver toxicities, which allows a very long and a prolonged administration, which is very important in this setting. Dr. Peter Li: These are all excellent points. Can you tell the listeners if there are any limitations that we should be concerned about, about this study? Dr. Maurice Pérol: Sure. This data comes from single-arm phase II studies. So, this is not comparative data. And a phase III trial, which compares taletrectinib to crizotinib, is ongoing to evaluate the superiority of taletrectinib over the standard of care. Another limitation comes from the lack of systematic brain imaging at each tumor evaluation in patients without brain metastases at baseline, not allowing to assess the intracranial PFS in all patients, and which did not allow us to assess the CNS protective issue from taletrectinib, especially in patients without brain metastases at baseline. Dr. Peter Li: Another question that I have is, with this novel TKI now available, how would you recommend the sequencing of these drugs? Would you start with someone on an alternate TKI and then reserve taletrectinib second line or later? Or would you use it upfront? Or does it depend? Dr. Maurice Pérol: Well, it is a very important question, as we have now different available TKIs. Looking at the efficacy-toxicity balance, I would strongly favor the use of taletrectinib in frontline setting, in first line. The response rate, the CNS activity, the duration of response with a very compelling 45 months median PFS, and moreover, the good tolerance profile over time are strong arguments in favor of giving taletrectinib in frontline. Generally speaking, the use of the most active agent as frontline treatment in lung cancer depending on an oncogenic addiction is probably the best way to improve the patient's outcome. This is true for patients with EGFR mutation, for patients with ALK fusions, and this is probably also true for patients with ROS1 fusion. So, I would probably argue in favor of a frontline use of taletrectinib. Dr. Peter Li: Listeners are going to ask, well, if you use taletrectinib upfront, then what are you going to use second line once they progress? Dr. Maurice Pérol: Well, we have some new compounds which are under development today. For example, the NVL-520, which is a very interesting compound, which seems also to be active in case of resistance mutation. But I do think that we have to use the best-in-class TKI in frontline because, you know, the extension of PFS after acquired resistance you can obtain with a second-line TKI is always shorter than the benefit you can obtain by using the most active agent in frontline. And this is true for the majority of oncogenic addiction in lung cancer. Dr. Peter Li: That makes sense. I also noticed that cognitive impairment wasn't listed in the safety table. Is that not an issue that you've observed at all with taletrectinib, or is it still an issue but less so because, like you mentioned earlier, because of its higher selectivity? Dr. Maurice Pérol: Well, this is a good question because we have some ROS1-targeting TKIs like repotrectinib, entrectinib, and even lorlatinib, with some neurological adverse events and some cognitive issues. Taletrectinib is a very selective ROS1-targeting TKI, and it spares very well the TrKB, for example, explaining that we did not observe any cognitive impairment with taletrectinib in the TRUST study, showing also with the low level of other neurological adverse events, dizziness, dysgeusia, for example,
JCO Editorial Fellow Dr. Ece Cali Daylan and JCO Associate Editor Dr. Thomas Stinchcombe discuss the ASCO 2025 Simultaneous Publication paper "Neoadjuvant Osimertinib for Resectable EGFR-Mutated Non-Small-Cell Lung Cancer." Transcript The guest on this podcast episode has no disclosures to declare. Dr. Ece Cali: Hello, and welcome to our 2025 ASCO Annual Meeting series, where we cover some of the top JCO papers published simultaneously with their abstract presentation at this year's meeting. I'm your host, Dr. Ece Cali, JCO Editorial Fellow, and I am joined by JCO Associate Editor, Dr. Tom Stinchcombe. In this episode, we will discuss the Journal of Clinical Oncology article and abstract presentation "Neoadjuvant Osimertinib for Resectable EGFR-Mutated Non–Small-Cell Lung Cancer.” NeoADAURA is a randomized global phase III study investigating the efficacy of neoadjuvant osimertinib-containing regimens in patients with resectable EGFR-mutated stage II to IIIB non–small-cell lung cancer. 358 patients were randomized 1:1:1 to receive osimertinib plus chemotherapy, osimertinib monotherapy, or placebo plus chemotherapy in the neoadjuvant setting. The primary endpoint was major pathological response. Osimertinib plus chemotherapy and osimertinib alone demonstrated MPR rates of 26% and 25%, respectively, compared to 2% in the chemotherapy plus placebo arm with a p-value of less than 0.001. Tom, can you please explain to our listeners how you interpret this data? Dr. Thomas Stinchcombe: Great question. Yeah, I think to give a little context, obviously, chemotherapy and immunotherapies preoperatively is becoming the standard of care. However, patients with EGFR-mutant lung cancer generally have not responded to immunotherapy, and many of the trials excluded patients with known EGFR mutation. There have been smaller phase II trials that had looked at EGFR TKIs preoperatively, but none of these were definitive. So I think that this trial is a big trial, and I think some of the strengths are that it has osimertinib alone and chemotherapy with osimertinib arms as compared to the standard of chemotherapy. I think it's going to be really interesting at the meeting to see how this is discussed by the discussant and also what the reaction is to its public presentation. And I think that's largely because there's an alternative paradigm now, surgical resection adjuvant osimertinib, that's available to patients. So I think this will be interesting to see what the reaction is to the induction therapy. For patients with known N2 disease, I've generally given some form of induction therapy prior to surgical resection. So I think that's the subgroup of patients that I'm most likely to employ this approach with based on the results. Dr. Ece Cali: So, in this trial, more than 90% of the patients on the osimertinib-containing regimens underwent curative-intent surgery. So, this speaks to the feasibility of the approach, and the higher MPR rate with osimertinib-containing regimens is encouraging. Event-free survival data is currently immature. You have already touched upon some of the strengths of the trial, but what are the weaknesses and the strengths of this trial? Dr. Thomas Stinchcombe: So, I mean, I think there are some weaknesses. A major pathological response was chosen as an endpoint, and there could be an argument that path CR is more of a prognostic marker. However, the rates of path CR are relatively low, so it would have been very hard to design a trial such as that. And then I think the trial started off as a preoperative trial but effectively became a perioperative trial with preoperative EGFR-TKI, postoperative osimertinib. And so I think it's going to be very hard to determine what the contribution of the components are. And then you've hit on another part that I think is very important when we interpret the data that the maturity on the event-free survival is only 15%, and most people are still on therapy. So the event-free survival, which is an important endpoint, is very immature right now. Dr. Ece Cali: And this trial was designed to compare the neoadjuvant approaches, hence the comparator arm here is neoadjuvant chemotherapy followed by surgery. So, considering the ADAURA trial results with upfront surgery followed by osimertinib as adjuvant, so how do you see this trial's impact on the current clinical practice? Dr. Thomas Stinchcombe: Well, very good question, I think one that we're still struggling with as we kind of look at this data. I think, for me, stage II patients will most likely go to surgery and then get adjuvant osimertinib, and then maybe the N2 patients will get an osimertinib-containing regimen as an induction therapy. I think one of the questions is does it really matter when you get the osimertinib as long as you get it at some point? And I think that's going to be the critical interpretation of some of the data at this point. Dr. Ece Cali: And how do you think this trial shapes the future research for patients with resectable EGFR-mutated lung cancer? Dr. Thomas Stinchcombe: Well, I mean, I think it shows that chemotherapy was really modestly active with an MPR rate of 2%, no pathological responses. And then I think you're going to have to look at an osimertinib plus another targeted therapy component. I think, you know, when I looked at the osimertinib versus the chemo-osimertinib arm, I also was sort of surprised that the MPR rate and the path CR rate were very, very similar. So I think that the question is would a double targeted therapy approach or some other approach matter? And I think it also sets a safety standard. And you touched on this in your comments, that there was not a disparity in terms of the rate of going to surgery or R0/R1 resections. So patients were not having progressive disease events or toxicities that prevented surgery. So I think it does give us good safety data.

JCO Editorial Fellow Dr. Lauren Shih and JCO Associate Editor Dr. Stephanie Wheeler discuss the ASCO 25 Simultaneous Publication paper "Use of Low-Value Cancer Treatments in Medicare Advantage Versus Traditional Medicare." Transcript The guest on this podcast episode has no disclosures to declare. Dr. Lauren Shih: Hello, and welcome to our 2025 ASCO annual meeting series where we cover some of the top JCO papers published simultaneously with their abstract presentations at this year's meeting. I'm your host, Dr. Lauren Shih, JCO editorial fellow, and I'm joined by JCO Associate Editor Dr. Stephanie Wheeler to discuss the Journal of Clinical Oncology article and abstract presentation "Use of Low-Value Cancer Treatments in Medicare Advantage Versus Traditional Medicare." Let's start with the relevance of the article. Dr. Wheeler, can you explain this to our listeners? Dr. Stephanie Wheeler: Thank you so much. Let's get right into it. So this article is really about understanding different types of Medicare plans and what we should expect to see in terms of their use of low-value treatments for cancer patients. So, as Medicare really is focused on trying to limit the use of low-value cancer treatments, we really need to better understand the drivers of variability. So we know that many cancer patients have multiple treatment options available to them. We also know that the vast majority of older adults beyond age 65 are insured by Medicare, and about half of them are on Medicare Advantage plans, which are serviced by private insurance. And private insurance companies in this case are receiving capitated payments for Medicare beneficiaries to manage their service utilization and reduce costs. So, with respect to Medicare Advantage versus the traditional fee-for-service Medicare, it's not really been known to what extent low-value treatments are differentially used by these types of plans for cancer patients. And so that was really the focus of this article. What the authors found is that across six different types of treatments, in general, the folks who were enrolled in Medicare Advantage plans had reduced use of low-value treatment. So that's a good sign for Medicare beneficiaries. And although the relative difference in that use was somewhat low, this translates to a significant number of Medicare enrollees across the country not receiving these low-value treatments. And of course, this translates to considerable savings at the society level. Dr. Lauren Shih: Are there any additional key results that we should review? Dr. Stephanie Wheeler: Yeah. So I'll tell you just a little bit more about the methods and also their findings. So they looked at six different low-value treatments, and this was in, again, 100% of national Medicare enrollees from 2015 through 2021. So the six low-value treatments that they examined were the use of G-CSFs among patients receiving low-risk chemotherapy and denosumab for those who had castration-sensitive prostate cancer. Then they also looked at four high-cost treatments, including using nab-paclitaxel instead of paclitaxel for patients with breast or lung cancer; second, adding bevacizumab to carboplatin plus paclitaxel for ovarian cancer; third, using brand-name drugs instead of generics when generics were available; and fourth, using biologics instead of biosimilars when biosimilars were available. And these are all, by the way, non-recommended treatments according to a variety of guidelines, including NCCN and ASCO's Choosing Wisely guidelines. So they used the Medicare claims data to examine use of these regimens. They also analyzed results by type of Medicare Advantage plan, whether people were enrolled in a health maintenance organization plan, or an HMO, or a preferred provider organization plan, or a PPO. They also looked at the largest Medicare Advantage insurers—including Aetna, Blue Cross Blue Shield, Cigna, Humana, and UnitedHealth—and limited their analyses to those that had complete encounter data. And what they found across the board is that the enrollees in Medicare Advantage plans generally had lower use of these low-value treatments. And the largest differences between Medicare Advantage and traditional Medicare plans were in the outcomes, including G-CSF use and using denosumab for castration-resistant prostate cancer, and then the combination of bevacizumab, carboplatin, and paclitaxel versus carboplatin and paclitaxel. And all of these had a change in use ranging from about 19% change to 24% change in use. This is significant as a field as we look at ways in which different plan organization can influence use of treatments, particularly given the excess cost of cancer care. This is something we really want to pay attention to. So I'd encourage folks to look more closely at the results by treatment type as well as the results by plan type to see a little bit more about what was going on across different plan types. Dr. Lauren Shih: Great. And are there any outstanding questions that need to be answered? Dr. Stephanie Wheeler: Yes, there always are, of course. I think the study has several strengths that are worth noting. First, they have 100% of Medicare enrollees, so there's national coverage there, which is, you know, quite outstanding. They also use an appropriate choice of analysis to help deal with some of the selection. So they use inverse probability of treatment weights, and they control for practice and county indicators to try to get some realistic adjustment for the selection that happens in terms of how patients are enrolled in different Medicare Advantage versus traditional fee-for-Medicare plans. These statistical approaches are a good idea, but they are limited by the observed variables that we can use for these kinds of adjustments. And so any unobserved—confounding or any unobserved factors that would influence selection in these plans aren't going to be captured well. So preferences, for example, that patients may have about different types of plans when they're insuring themselves and their families may not be captured. Second, the data that are used are only encounter data from those plans with complete records. That may mean that smaller Medicare Advantage insurers or those that don't have as comprehensive records are not included. So this may not be reflective of their practice patterns. And then third, of course, this only looked at six different low-value cancer treatments. It remains to be seen whether this kind of finding extends to other types of low-value cancer treatments, and that's an opportunity for future study. Finally, I would say that we don't exactly know why these patterns exist. It could be that Medicare Advantage plans have different approaches to prior authorization. They could have more in-house quality control and management to really understand, among their population for whom they're receiving Medicare Advantage payments, to really look at care quality and assess Choosing Wisely guidelines. We don't know exactly how that's playing out. And so we need additional data to really figure out what's working here and what are opportunities for future policy and payment innovations that can further reduce low-value care.

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

JCO Editorial Fellow Peter Li and JCO Associate Editor Eileen O'Reilly discuss the ASCO 25 Simultaneous Publication paper "Tumor-Treating Fields with Gemcitabine and Nab-Paclitaxel for Locally Advanced Pancreatic Adenocarcinoma: Randomized, Open-Label, Pivotal, Phase 3 PANOVA-3 Study." Transcript The guest on this podcast episode has no disclosures to declare. Dr. Peter Li: Hello, and welcome to our 2025 ASCO Annual Meeting series, where we cover some of the top JCO papers published simultaneously with their abstract presentation at this year's meeting. I'm your host, Dr. Peter Li, and I'm joined by JCO Associate Editor Dr. Eileen O'Reilly to discuss the Journal of Clinical Oncology article and abstract presentation "Tumor Treating Fields with Gemcitabine and Nab-Paclitaxel for Locally Advanced Pancreatic Adenocarcinoma: Randomized, Open-Label, Pivotal, Phase 3 PANOVA-3 Study." Now, let's start with the relevance of the article. Eileen, can you explain this study to our listeners? Dr. Eileen O'Reilly: Thanks very much, Peter, for the invitation today to discuss this. Yes, so this is a positive phase 3 trial that was conducted in locally advanced, unresectable pancreas cancer. Patients were randomized to receive either gemcitabine and nab-paclitaxel, international standard, with or without tumor-treating fields. And this is a device like a battery pack that you would wear with a goal to wear that approximately 18 hours a day. And the primary endpoint of this study was overall survival, with key secondary endpoints of tumor response, progression-free survival, looking at pain-free survival, and distant progression-free survival. So, the primary endpoint was met with a median overall survival of 16.2 months compared to 14.2 months on the intervention versus control arm, with a hazard ratio of 0.82. And so that met the pre-specified boundary. There was not an increase in progression-free survival, but there was an increase in control of pain on the tumor-treating fields study. So, it was a large, global study, community, academic sites, randomized 570 people, and it supports what I think we've seen in other difficult-to-treat malignancies using tumor-treating fields, that there's a signal of interest. Dr. Peter Li: Can you speak to some of the strengths and weaknesses of this study? Dr. Eileen O'Reilly: So, strengths: it was a large study. It included community sites, it included academic sites. It included ECOG performance status 0, 1, and some patients with 2. The intent was locally advanced. It probably is fair to say that there were some patients who had more advanced disease based on early progression, based on relatively high CA 19-9 for a percentage of people. But likely that was, with random assignment, that would have presumably fallen out between the arms. The inclusion of patients with a lower performance status is nice to see in large phase 3 studies in pancreas cancer. So, they would be some of the strengths. So maybe some of the limitations are the fact that it's an open-label study - so, always some biases inherent in that. Acknowledging that the primary endpoint was overall survival, presumably that wouldn't be directly influenced by that. And there was an imbalance of women on the control arm, and women do fare a little better in this disease, so possibly kind of weighted one of the study arms a little bit. But nonetheless, I think it was a rigorously designed and rigorously conducted phase 3 trial. It's always hard to fully interpret the signal in locally advanced disease because of the fact that some patients go on to surgery, some patients have a treatment switch of cytotoxic therapy, some patients will go on to radiation. And the endpoint here of overall survival, to a degree, eliminates some of that. So, the benchmark, I think, was generally high here. Dr. Peter Li: Gotcha. And then with these findings and this positive study, how do you foresee this research being implemented and how it will impact clinical practice moving forward? Dr. Eileen O'Reilly: I think there'll be an educational need to introduce this approach to the community and to the pancreas cancer world. Again, there's a precedent in glioblastoma and data from other diseases, so there's some familiarity with this. I think people always want to understand how it works and why it works, and that's something that we'll look forward to hearing more about mechanistically, and also seeing how it can be built upon. And there's some intriguing data with the combination of tumor-treating fields and immunotherapy that's being evaluated in the PANOVA-4 study. So, we'll stay tuned to hear how that reads out in due course. But I think overall, it'll be educational and learning, managing the cutaneous impacts or some skin irritation effects from this, and building on this signal in locally advanced disease. Dr. Peter Li: Well, thank you so much, Eileen, for your time and for speaking about the JCO article, "Tumor Treating Fields with Gemcitabine and Nab-Paclitaxel for Locally Advanced Pancreatic Adenocarcinoma: Randomized, Open-Label, Pivotal, Phase 3 PANOVA-3 Study."

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

In this JCO Article Insights episode, host Michael Hughes summarizes "Co-Occurrence of Cytogenetic Abnormalities and High-Risk Disease in Newly Diagnosed and Relapsed/Refractory Multiple Myeloma" by Kaiser et al, published February 18, 2025, followed by an interview with JCO Associate Editor Suzanne Lentzsch. Transcript Michael Hughes: Welcome to this episode of JCO Article Insights. This is Michael Hughes, JCO's editorial fellow. Today I have the privilege and pleasure of interviewing Dr. Suzanne Lentzsch on the “Co-Occurrence of Cytogenetic Abnormalities and High-Risk Disease in Newly Diagnosed and Relapsed/Refractory Multiple Myeloma” by Dr. Kaiser and colleagues. At the time of this recording, our guest has disclosures that will be linked in the transcript. The urge to identify patients with aggressive disease, which is the first step in any effort to provide personalized medical care, is intuitive to physicians today. Multiple myeloma patients have experienced heterogeneous outcomes since we first started characterizing the disease. Some patients live for decades after treatment. Some, irrespective of treatment administered, exhibit rapidly relapsing disease. We term this ‘high-risk myeloma’. The Durie-Salmon Risk Stratification System, introduced in 1975, was the first formal effort to identify those patients with aggressive, high-risk myeloma. However, the introduction of novel approaches in therapeutic agents—autologous stem cell transplantation with melphalan conditioning, proteasome inhibitors like bortezomib, or immunomodulatory drugs like lenalidomide—rendered the Durie-Salmon system a less precise predictor of outcomes. The International Staging System in 2005, predicated upon the burden of disease as measured by beta-2 microglobulin and serum albumin, was the second attempt at identifying high-risk myeloma. It was eventually supplanted by the Revised International Staging System (RISS) in 2015, which incorporated novel clinical and cytogenetic markers and remains the primary way physicians think about the risk of progression or relapse in multiple myeloma. Much attention has been focused on the canonically high-risk cytogenetic abnormalities in myeloma, typically identified by fluorescence in situ hybridization: translocation t(4;14), translocation t(14;16), translocation t(14;20), and deletion of 17p. Much attention also has been focused on the fact that intermediate-risk disease, as defined by the RISS, has been shown to be a heterogeneous subgroup in terms of survival outcomes. The RISS underwent revision in 2022 to account for such heterogeneity and has become the R2-ISS, published here in the Journal of Clinical Oncology first in 2022. Translocations t(14;16) and t(14;20) were removed, and gain or amplification of 1q was added. Such revisions to core parts of a modern risk-stratification system reflect the fact that myeloma right now is in flux, both in treatment paradigms and risk-stratification systems. The field in recent years has undergone numerous remarkable changes, from the advent of anti-CD38 agents to the introduction of cellular and bispecific therapies, to the very technology we use to investigate genetic lesions. The major issue is that we're seeing numerous trials using different criteria for the definition of high-risk multiple myeloma. This is a burgeoning problem and speaks very much now to a critical need for an effort to consolidate all these criteria on at least cytogenetic lesions as we move into an era of response-adapted treatment strategies. The excellent article by Kaiser and colleagues, published in the February 2024 edition of the JCO, does just that in a far-ranging meta-analysis of data from 24 prospective therapeutic trials. All 24 trials were phase II or III randomized controlled trials for newly diagnosed and relapsed/refractory multiple myeloma. The paper takes a federated analysis approach: participants provided summaries and performed prespecified uniform analyses. The high-risk cytogenetic abnormalities examined were translocation t(4;14), gain or amplification of 1q, deletion of 17p, and translocation t(14;16), if included in the original trials. All of these were collected into zero, single, or double-hit categories, not unlike the system currently present in diffuse large B-cell lymphomas. The outcomes studied were progression-free survival and overall survival, with these analyses adhering to modified ITT principles. The authors also performed prespecified subgroup analyses in the following: transplant-eligible newly diagnosed myeloma, transplant non-ineligible newly diagnosed myeloma, and relapsed/refractory myeloma. They, in addition, described heterogeneity by the I2 statistic, which, if above 50%, denotes substantial heterogeneity by the Cochrane Review Handbook, and otherwise performed sensitivity analyses and assessed bias to confirm the robustness of their results. In terms of those results, looking at the data collected, there was an appropriate spread of anti-CD38-containing and non-containing trials. 7,724 patients were evaluable of a total 13,926 enrolled in those 24 trials: 4,106 from nine trials in transplant-eligible myeloma, 1,816 from seven trials in transplant non-ineligible myeloma, and 1,802 from eight trials in relapsed/refractory disease. ISS stage for all patients was relatively evenly spread: stage I, 34.5%; stage II, 37%; stage III, 24%. In terms of high-risk cytogenetic lesions, double-hit disease was present in 13.8% of patients, and single-hit disease was present in 37.4%. In terms of outcomes, Kaiser and colleagues found a consistent separation in survival outcomes when the cohort was stratified by the number of high-risk cytogenetic lesions present. For PFS, the hazard ratio was for double-hit 2.28, for single-hit 1.51, without significant heterogeneity. For overall survival, the hazard ratio was for double-hit disease 2.94, single-hit disease 1.69, without significant heterogeneity except in patients with double-hit disease at 56.5%. By clinical subgroups, hazard ratios remained pretty consistent with the overall cohort analysis. In transplant-eligible newly diagnosed myeloma, the hazard ratio for progression is 2.53, overall survival 4.17. For transplant non-ineligible, 1.97 progression, 2.31 mortality. Relapsed/refractory disease progression 2.05, overall mortality 2.21, without significant heterogeneity. Of trials which started recruitment since 2015, that is to say, since daratumumab was FDA approved and thus since an anti-CD38 agent was incorporated into these regimens, analysis revealed the same results, with double-hit myeloma still experiencing worse survival by far of the three categories analyzed. Risk of bias overall was low by advanced statistical analysis. In terms of subgroup analysis, double-hit results for transplant-eligible newly diagnosed myeloma may have been skewed by smaller study effects, where the upper bound of the estimated hazard ratio for mortality reached into the 15 to 20 range. In conclusion, from a massive amount of data comes a very elegant way to think about the role certain cytogenetic abnormalities play in multiple myeloma. A simple number of lesions - zero, one, or at least two - can risk-stratify. This is a powerful new prognostic biomarker candidate and, somewhat soberingly, also may confirm, or at least suggests, that anti-CD38 agents are unable to overcome the deleterious impact of certain biologic characteristics of myeloma. Where do we go from here? This certainly needs further a priori prospective validation. This did not include cellular therapies. The very scale at which this risk-stratification system operates, agnostic to specific genetic lesion, let alone point mutations, lends itself also to further exploration. And to discuss this piece further, we welcome the one and only Dr. Suzanne Lentzsch to the episode. Dr. Lentzsch serves as an associate editor for JCO and is a world-renowned leader at the bleeding edge of plasma cell dyscrasia research. Dr. Lentzsch, there are several new investigations which suggest that translocation t(4;14), for example, is itself a heterogeneous collection of patients. There are other studies which suggest that point mutations in oncogenes like TP53, which were not assessed in Kaiser et al., carry substantial detrimental impact. Is this classification system - no-hit, single-hit, double-hit - too broad a look at tumor genetics? And how do you think we will end up incorporating ever more detailed investigations into the genetics of multiple myeloma moving forward? Dr. Suzanne Lentzsch: Michael, first of all, excellent presentation of that very important trial. Great summary. And of course, it's a pleasure to be here with JCO and with you to discuss that manuscript. Let me go back a little bit to high-risk multiple myeloma. I think over the last years, we had a lot of information on what is high-risk multiple myeloma, and I just want to mention a couple of things, that we separate not only cytogenetically high-risk multiple myeloma, we also have functional high-risk multiple myeloma, with an early relapse after transplant, within 12 months, or two years after start of treatment for the non transplant patients, which is difficult to assess because you cannot decide whether this is a high-risk patient before you start treatment. You only know that in retrospective. Other forms of high-risk: extramedullary disease, circulating tumor cells/plasma cell dyscrasia, patients who never achieve MRD positivity, extramedullary multiple myeloma, or even age and frailty is a high risk for our patients. Then we have gene expression and gene sequencing. So there is so much information currently to really assess what is high-risk multiple myeloma, that is very difficult to find common ground and establish something for future clinical trials. So what Dr. Kaiser did was really to develop a very elegant system with information we should all have.
Host Dr. Davide Soldato and guest Dr. Harriet Kluger discuss the JCO article "Phase II Trial of Pembrolizumab in Combination With Bevacizumab for Untreated Melanoma Brain Metastases." Transcript The guest on this podcast episode has no disclosures to declare. Dr. Davide Soldato Hello and welcome to JCO After Hours, the podcast where we sit down with authors from some of the latest articles published in the Journal of Clinical Oncology. I am your host, Dr. Davide Soldato, Medical Oncologist at Ospedale San Martino in Genoa, Italy. Today, we are joined by JCO author Dr. Harriet Kluger. Dr. Kluger is a professor of medicine at Yale School of Medicine, Director of the Yale SPORE in Skin Cancer, and an internationally recognized expert in immuno-oncology for melanoma and renal cell carcinoma. She leads early-phase and translational trials that pair novel immunotherapies with predictive biomarkers to personalized care. Today, Dr. Kluger and I will be discussing the article titled "Phase 2 Trial of Pembrolizumab in Combination with Bevacizumab for Untreated Melanoma Brain Metastases." In this study, Dr. Kluger and colleagues evaluated four cycles of pembrolizumab plus the anti-VEGF antibody bevacizumab followed by pembrolizumab maintenance in patients with asymptomatic non-hemorrhagic melanoma brain metastases that had not previously received PD-1 therapy. Thank you for speaking with us, Dr. Kluger. Dr. Harriet Kluger Thank you for inviting me. The pleasure is really all mine. Dr. Davide Soldato So to kick off our podcast, I just wanted to ask if you could outline a little bit the biological and clinical rationale that led you to test this type of combination for patients with untreated brain metastases from metastatic melanoma. Dr. Harriet Kluger Back in approximately 2012, patients who had untreated brain metastases were excluded from all clinical trials. So by untreated, I mean brain metastases that had not received local therapy such as surgery or radiation. The reason for it was primarily because there was this fear that big molecules wouldn't penetrate brain lesions because they can't pass the blood-brain barrier. Turns out that the blood-brain barrier within a tumor is somewhat leaky and drugs sometimes can get in there. When PD-1 inhibitors were first identified as the next blockbuster class of drugs, we decided to conduct a phase 2 clinical trial of pembrolizumab monotherapy in patients with untreated brain metastases. We actually did it also in lung cancer, and we could talk about that later on. Responses were seen. The responses in the brain and the body were similar. They were concordant in melanoma patients. Now, at approximately that time, also another study was done by the Australian group by Dr. Georgina Long, where they did a randomized trial where patients who didn't require immediate steroid therapy received either nivolumab alone or nivolumab with ipilimumab, and the combination arm was substantially superior. Subsequently, also, Bristol Myers Squibb also conducted a large phase 2 multicenter trial of ipilimumab and nivolumab in patients with untreated brain metastases. And there, once again, they saw that the responses in the brain were similar to the responses in the body. Now, somewhere along the line there, we completed our anti-PD-1 monotherapy trial. And when we looked at our data, we still didn't have the data on ipilimumab and nivolumab. And our question was, “Well, how can we do better?” Just as we're always trying to do better. We saw two really big problems. One was that patients had a lot of perilesional edema. And the other one was that we were struggling with radiation necrosis in lesions that were previously Gamma Knifed. The instance of radiation necrosis was in excess of 30%. So the rationale behind this study was that if we added bevacizumab, maybe we could treat those patients who had some edema, not requiring steroids, but potentially get them on study, get that PD-1 inhibitor going, and also prevent subsequent radiation necrosis. And that was the main rationale behind the study. We had also done some preclinical work in mouse models of melanoma brain metastases and in an in vitro blood-brain barrier model where we showed that bevacizumab, or anti-VEGF, really tightens up those leaky basement membranes and therefore would be very likely to decrease the edema. Dr. Davide Soldato Thank you very much for putting in context the combination. So this was a phase 2 trial, and you included patients who had at least one lesion, and you wanted lesions that were behind 5 and 20 millimeters. Patients could be included also if the brain metastasis was higher in dimension than 20 millimeters, but it had to be treated, and it was then excluded from the evaluation of the primary objective of the trial. So regarding, a little bit, these characteristics, do you think that this is very similar to what we see in clinical practice? And what does this mean in terms of applicability of these results in clinical practice? Dr. Harriet Kluger So that's an excellent question. The brain metastasis clinical research field has somewhat been struggling with this issue of inclusion/exclusion criteria. When we started this, we showed pretty clearly that 5 to 10 millimeter lesions, which are below the RECIST criteria for inclusion, are measurable if you use MRIs with slices that are 1 to 2 millimeters. Most institutions in the United States do use these high-resolution MRIs. I don't know how applicable that is on a worldwide scale, but we certainly lowered the threshold for inclusion so that patients who have a smattering of small brain metastases would be eligible. Now, patients with single large brain metastases, the reason that we excluded those from the trial was because we were afraid that if a patient didn't respond to the systemic therapy that we were going to give them, they could really then develop severe neurological symptoms. So, for patient safety, we used 20 millimeters as the upper level for inclusion. Some of the other trials that I mentioned earlier also excluded patients with very large lesions. Now, in practice, one certainly can do Gamma Knife therapy to the large lesions and leave the smaller ones untreated. So I think it actually is very applicable to clinical practice. Dr. Davide Soldato Thank you very much for that insight, because I think that sometimes criteria for clinical trials, they have to be very restrictive. But then we know that in clinical practice, the applicability of these results is probably broader. So, going a little bit further in the results of the study, I just wanted a little bit of comment from you regarding what you saw in terms of intracranial response rate and duration of response among patients who obtained a response from the combination treatment. Dr. Harriet Kluger So we were actually surprised. When we first designed this study, as I said earlier, we weren't trying to beat out ipilimumab and nivolumab. We were really just trying to exclude those patients who wouldn't have otherwise been eligible for ipilimumab and nivolumab because of edema or possibly even previous radiation necrosis. So it was designed to differentiate between a response rate of 34%, and I believe the lower bound was somewhere in the 20s, because that's what we'd seen in the previous pembrolizumab study. What we saw in the first 20 patients that we enrolled was actually a response rate that far exceeded that. And so we enrolled another cohort to verify that result because we were concerned about premature publishing of a result that we might have achieved just by chance. The two cohorts were very similar in terms of the response rates. And certainly this still needs to be verified in a second study with additional institutions. We did include the Moffitt Cancer Center, and the response rate with Moffitt Cancer Center was very similar to the Yale Cancer Center response rate. Now, your other question was about duration of response. So the other thing that we started asking ourselves was whether this high response rate was really because the administration of the anti-VEGF will decrease the gadolinium enhancement and therefore we might actually just be seeing prettier scans but not tumor shrinkage. And the way to differentiate those two is by looking at the duration of the response. Median progression-free survival was 2.2 years. That's pretty long. The upper bound on the 95% confidence interval was not reached. I can't tell you that the duration is as good as the duration would be when you give ipilimumab. Perhaps it is less good. This was a fairly sick population of patients, and it included some who might not have been able to receive ipilimumab and nivolumab. So it provides an alternative. I do believe that we need to do a randomized trial where we compare it to ipilimumab and nivolumab, which is the current standard of care in this patient population. We do need to interpret these results with caution. I also want to point out regarding the progression-free survival that we only gave four doses of anti-VEGF. So one would think that even though anti-VEGF has a long half-life of three or four weeks, two years later, you no longer have anti-VEGF effect, presumably. So it does something when it's administered fairly early on in the course of the treatment. Dr. Davide Soldato So, in terms of clinical applicability, do you see this combination of pembrolizumab and bevacizumab - and of course, as we mentioned, this was a phase 2 trial. The number of patients included was not very high, but still you saw some very promising results when compared with the combination of ipilimumab and nivolumab. So do you see this combination as something that should be given particularly to those patients who might not be able to receive ipilimumab and nivolumab? So, for example, patients who are very symptomatic from the start or require a high dose of steroids, or also to provide
In this JCO Article Insights episode, host Joseph Mathew summaries Pancreatic Adenocarcinoma: Long-Term Outcomes of Adjuvant Therapy in the ESPAC4 Phase III Trial, by Palmer, et al published December 5, 2024. Transcript Joseph Mathew: Hello and welcome to the Journal of Clinical Oncology Article Insights. I'm your host, Joseph Mathew, and today we will be discussing the article "Long-Term Survival in Resected Pancreatic Ductal Adenocarcinoma with Adjuvant Gemcitabine plus Capecitabine Compared to Modified FOLFIRINOX from the ESPAC-4 and the PRODIGE 24 Trials" by Dr. Palmer et al. To summarize the relevant evidence, the ESPAC-4 was a European phase 3 multicenter randomized clinical trial published in 2017 comparing adjuvant gemcitabine and capecitabine (GemCap) with gemcitabine monotherapy following macroscopic margin-negative resections for operable pancreatic ductal adenocarcinoma (PDAC). The trial had included non-metastatic patients aged 18 years or older, World Health Organization (WHO) performance scores of 2 or less, creatinine clearance of at least 50 mL/min, and a life expectancy of over three months who had not received any prior anticancer treatment. Patients who had undergone R2 resections were selectively excluded. Eligible participants were randomized 1:1 within 12 weeks of pancreatectomy to one of the two treatment arms, with chemotherapy initiated within two weeks from the date of randomization. The regimens involved six cycles, each lasting four weeks, for an overall duration of 24 weeks. In the monotherapy arm, gemcitabine dosed at 1 g/m² was given as an intravenous infusion once a week for three weeks, followed by one week off. In the GemCap arm, capecitabine dosed at 1660 mg/m² was added to gemcitabine, given daily for three weeks, followed by one week off. Patients were followed up every three months, with the primary endpoint being overall survival (OS). The study showed that at a median follow-up of 43.2 months, GemCap was associated with a significantly longer OS than gemcitabine alone. Subsequently, in 2018, the Phase 3 randomized PRODIGE 24 trial was conducted in centers across France and Canada, comparing adjuvant modified FOLFIRINOX (mFOLFIRINOX) with gemcitabine in a similar subset of patients with resected PDAC and reported longer OS with the mFOLFIRINOX regimen. This study, however, had more restrictive eligibility criteria when compared to ESPAC-4, including patients aged under 80 years, WHO performance status of 0 or 1, with no significant cardiovascular disease, and a postoperative serum CA 19-9 of less than 180 U/mL. There was hence a subset of ESPAC-4 patients who did not meet the eligibility criteria for mFOLFIRINOX as set by the PRODIGE 24. The present study was conducted to estimate the overall 5-year survival rates for patients of ESPAC-4 receiving GemCap and gemcitabine, further stratifying survival in either arm according to the status of the surgical margins (R status) and the resected nodes (N status), and also to investigate whether GemCap retained a survival benefit over gemcitabine in PRODIGE 24-ineligible patients. A total of 732 patients, evenly distributed between both arms, were followed up for a median period of 104 months. Adjuvant GemCap was found to retain its survival advantage over gemcitabine, with a significantly longer median OS of 31.6 months when compared to 28.4 months with gemcitabine alone. Further subgroup analysis was performed with reference to the resection margins and the nodal status. As a reminder, in the ESPAC-4 trial, 60% of patients were found to have microscopically positive margins (an R1 resection), and 80% were node-positive. The difference in survival was greater in patients undergoing microscopic margin-negative resections (R0) who experienced a median OS of 49.9 months with GemCap when compared to 32.2 months with gemcitabine. Node-negative patients also had a significantly greater 5-year OS rate with GemCap of 59% versus 53% with gemcitabine monotherapy. However, it is important to note that no significant difference in survival outcomes was observed in margin-positive (R1) or node-positive patients in the two arms. The investigators also evaluated GemCap in the subgroup of 193 patients (comprising 26.4% of the ESPAC-4 cohort) who were not considered to have met the eligibility criteria for PRODIGE 24. The survival benefit of combination therapy was retained in this group, with patients receiving GemCap experiencing a median survival of 25.9 months compared to 20.7 months with adjuvant gemcitabine. Although cross-trial comparisons have limited validity, good agreement was noted in adverse grade 3 or greater toxicity associated with the control gemcitabine arms of ESPAC-4 and PRODIGE 24, serving as the basis for a qualitative comparison of toxicities between mFOLFIRINOX and GemCap. Neutropenia was more prevalent in the GemCap arm, affecting 40.8% of patients compared to 28.4% with mFOLFIRINOX. However, granulocyte colony-stimulating factor (G-CSF) was administered to 62.2% of patients in PRODIGE 24. Palmar-plantar erythrodysesthesia (PPE) was also more prevalent with GemCap. Patients on mFOLFIRINOX were more likely to observe grade 3 or greater fatigue, diarrhea, nausea and vomiting, sensory peripheral neuropathy, and paresthesias. The investigators concluded that GemCap was the standard adjuvant treatment for patients with PDAC undergoing an upfront resection who were not feasible for mFOLFIRINOX. Further exploratory analysis revealed that patients under the age of 70 who had undergone a microscopic margin-negative (R0) resection for node-negative PDAC were likely to derive an OS benefit from the addition of capecitabine to gemcitabine in the adjuvant setting. In contrast, mFOLFIRINOX would be more effective than gemcitabine in patients with positive margins (R1) or involved nodes, as per the PRODIGE 24 trial.

Host Dr. Davide Soldato and guests Dr. Jessica Burris discuss the article "Longitudinal Results from the Nationwide Just ASK Initiative to Promote Routine Smoking Assessment in American College of Surgeons Accredited Cancer Programs" and how persistent smoking following cancer diagnosis causes adverse outcomes while smoking cessation can improve survival. TRANSCRIPT The guest on this podcast episode has no disclosures to declare. Dr. Davide SoldatoHello and welcome to JCO After Hours, the podcast where we sit down with authors from some of the latest articles published in the Journal of Clinical Oncology. I am your host, Dr. Davide Soldato, medical oncologist at Ospedale San Martino in Genoa, Italy. Today we are joined by JCO author Dr. Jessica Burris. Dr. Burris is an Associate professor of Psychology at the University of Kentucky and co leader of the Cancer Prevention and Control Research Program at the Markey Cancer Center. Her research focuses on smoking cessation among cancer survivors, health disparities, and behavioral interventions to promote health equity. She also leads the BIRDS Lab, which explores the intersection of smoking, social determinants of health, and cancer survivorship. Today I will be discussing with Dr. Burris on the article titled Longitudinal Results from the Nationwide Just Ask Initiative to Promote Routine Smoking Assessment in American College of Surgeons Accredited Cancer Program. So, thank you for Speaking with us, Dr. Burris. Dr. Jessica BurrisThank you for inviting me. Dr. Davide SoldatoSo today we'll be discussing an important study on the implementation of smoking assessment in cancer care and specifically through the Just Ask Initiative. So, we know that tobacco use is a critical factor in cancer treatment outcomes in general, and yet integrating systematic smoking assessment into oncology care has faced various challenges. So, Dr. Burris, to start off our interview, I would like to ask you to briefly introduce the Just Ask Initiative for those of our readers and listeners who may not be familiar with it. So, a little bit about the primary goals and why do you think that routine smoking assessment is such an important aspect of cancer care and why the Just Ask Initiative focuses on this specific issue? Dr. Jessica BurrisSure. So, as you mentioned before, smoking is a really critical factor in terms of cancer care and cancer outcomes. It impacts a lot of things, from complications after surgery up into cancer mortality, but it also impacts patient's quality of life. Their pain may be more severe, they're more tired, their distress levels are higher. So, there's just a lot of different reasons why we need to understand and address smoking in the context of cancer care. But like you said too, there's a lot of barriers as well. But in order to effectively treat nicotine dependence and tobacco use, we really need to know who is currently smoking. And so that was really the driver for Just Ask, wanting to make sure that we are asking every person with cancer at their diagnosis and as they go through treatment, what their smoking history is, if they are currently smoking, which we usually consider to be any smoking or other tobacco use in the past 30 days, so that once we can identify that person, then we know who we need to help. Dr. Davide SoldatoThank you very much. That was very clear. And in terms of methodology, Just Ask was really a quality improvement type of initiative that involved the programs that were contacted and approached to participate in this type of initiative. And the methodology is pretty standard for this type of implementation science, which is the Plan Do Study Act methodology. So just a little bit of background on this type of methodology and why do you think it might be so successful when implementing these types of changes at the structural level and when we are implementing these types of programs. Dr. Jessica BurrisRight. So, the American College of Surgeons requires all the accredited cancer programs, both Commission on Cancer and the NAPBC or the ones that focus on breast cancer, to do at least one quality improvement project annually. And most of the programs do use the evidence-based Plan Do Study Act approach. I think it's a great one. It has a lot of evidence behind it, but it also is very practical or pragmatic. So, you're using data from your local healthcare system or clinic or program to inform what it is that you do. And then you're constantly pulling data out to see how well you're addressing the clinical practice change that you're hoping to achieve. And so, data is going in and coming out and you're using that to inform exactly what it is that you're doing over time. So, it's an iterative approach to practice change and again, one that has proven successful time and time again. And so that's the program that these programs and Just Ask used in order to increase the frequency by which they ask patients about smoking. Dr. Davide SoldatoSo as you were saying, the main objective of the initiative was really to understand if we are asking patients diagnosed with cancer and survivors if they are smoking. And how can we better report this information inside of the medical chart of the patient. So, what was the primary endpoint or the objective that you had for this type of intervention? And can you give us a little bit of results? So, what did you find the implementation of this quality improvement? How did it change the percentages of patients that were asked about smoking habits? And a little bit, what is your opinion on the results that you obtain in the study? Dr. Jessica BurrisSure. So, the goal was simple and that was to have an ask rate that was at least 90%. The way that we defined an ask rate is among all newly diagnosed cancer patients, how many were asked about their smoking history and their current status at that initial visit? And so, we wanted all of the participating programs who opted in to Just Ask in 2022 to achieve that 90% ask rate by the end of this one-year quality improvement project. And again, using the Plan Do Study Act approach, it was a very pragmatic study in some ways. So, what we did was we provided an intervention change package that we made available online. And programs could access that whenever they needed to and pull-down educational resources, patient facing materials, practical tools for changing the EHR or pulling data out of the EHR, any of those number of things. And then we also hosted webinars over the course of the year. And those webinars were great because half the time they were in response to questions that programs were asking as they went through the Just Ask QI project. And the other half of time we were really just reminding programs of the rationale and the reason for making sure that they're asking. And then of course, letting them know that they don't have to stop there, they should be advising patients to quit and assisting them with cessation. Even though that wasn't the goal of Just Ask, the goal again of Just Ask was getting that 90% rate. And so, we had over 750 programs who opted in to Just Ask and did this QI study with us, and it was successful. So, we met the goal, or rather the programs met the goal of that 90% ask rate. And that was maintained over time. And that was just fantastic. So again, we know that the end goal is really to assist patients with quitting, but we can't do that unless we know who to help. And so, you have to ask first. And again, they were able to do that. Dr. Davide SoldatoSo thank you very much. The quality improvement program was absolutely successful. And to go a little bit in the numbers, by the end of the one-year implementation of the program, you report a 98% rate of asking patients who first approached the centers or over time if they were or not smokers. So, you said before that you targeted a 90% ask rate in terms of smoking habits. But when looking at the data, I noticed that you already had in the baseline survey where you asked the programs about what were the practice before the implementation of the Just Ask initiative, already something that was quite close to the 90%. And yet, despite starting from such a good point, which was basically your endpoint, you still observed a major change over the years of the implementation. So, I wanted to just underline a little bit what is the value of this type of programs. And still starting from such a very high standard still, we managed to further improve. And as you were saying, this is pivotal and I think it's fundamental to really understand and see who are the patients that we need to refer and then to help in the smoking cessation. So, I just wanted a little bit of a comment on these very important results, despite already starting from a very good background from the centers. Dr. Jessica BurrisYeah, I'm glad that you brought up the baseline. So, I think one thing that's important about this study is that we looked at our ask rate or the asking as a clinical practice in two different ways. So, the 98% that you referred to that we found at the final survey is based on a response to a question on the frequency of asking. So, it's a Likert type question. And essentially what we did was we combined programs that reported usually asking or almost always asking into one, and that's where we arrived at the 98%. And at baseline it was 92%. What's interesting though is that we also asked them to report the specific number of patients who were seen in their cancer program during the prior six months and the number of patients who were asked about smoking in the prior six months. And with that we could get a proportion. And in every case, the self-report Likert question had a higher outcome than the raw data based on the data that was pulled from the EHR. And so, we saw this increase significantly over time, both in the self-report Likert question, but also in the EHR based data. And
In this JCO Article Insights episode, Lauren Shih summaries "Longitudinal Results From the Nationwide Just ASK Initiative to Promote Routine Smoking Assessment in American College of Surgeons–Accredited Cancer Programs" by Jessica L. Burris, et al published November 19, 2024. Come back for the next episode where JCO After Hours host, Dr. Davide Soldato interviews the author of the JCO article discussed, Dr. Jessica Burris. TRANSCRIPT Lauren Shih: Hello and welcome to JCO Article Insights. I'm your host Lauren Shih, and today we will be discussing the article, “Longitudinal Results From the Nationwide Just ASK Initiative to Promote Routine Smoking Assessment in American College of Surgeons–Accredited Cancer Programs” by Dr. Jessica Burris and colleagues published in the March issue of JCO. This study reports the finding of the Just ASK Initiative, an effort aimed at improving universal smoking assessment in cancer programs nationwide. We know that smoking after a cancer diagnosis is associated with numerous negative outcomes including worse survival, increased treatment related complications, poorer quality of life and higher healthcare costs. Patients who smoke are also at increased risk for cancer recurrence and second primary malignancies. Despite these risks, data show that a significant number of patients with newly diagnosed cancer still smoke and around 15% of cancer survivors continue smoking. Recognizing this discrepancy, national oncology organizations strongly recommend routine smoking assessment and cessation support as part of standard cancer care. However, despite these guidelines, smoking assessment and cessation assistance remain inconsistent across oncology practices. Surveys show that most National Cancer Institute designated cancer centers have insufficient resources to effectively support smoking cessation efforts. To address this gap, several large scale initiatives have been launched, including efforts by the National Cancer Institute, the Canadian Partnership Against Cancer, and the American College of Surgeons. The largest of these initiatives, through the American College of Surgeons, is the subject of our report today. In 2022, the American College of Surgeons introduced the Just ASK Quality Improvement Program with the goal of increasing routine smoking assessment. As member institutions, accredited programs are required to complete at least one quality improvement program annually. And in 2022, 40% of programs chose to participate in Just ASK. The primary goal of this quality improvement program was to ask at least 90% of newly diagnosed cancer patients about their smoking status. Offering smoking cessation support was encouraged, but not a mandatory component or primary endpoint for the initiative. To implement Just ASK, participating programs used a well-established Plan-Do-Study-Act methodology which is a structured, iterative approach for improving healthcare processes. Programs used local quality improvement teams and resources for implementation and had access to online training, educational webinars, and technical resources to help integrate smoking assessment into routine care. Programs completed three surveys: a baseline survey reflecting smoking assessment practices in the year before Just ASK; a midpoint survey after six months of participation; and a final survey after one year in the program. The surveys assess program characteristics, barriers to smoking assessment, readiness to change, and the frequency of smoking related clinical practices such as asking about smoking, documenting smoking status, and advising smoking cessation. Programs reported on implementation strategies they adopted to improve smoking assessment. Finally, programs reported the number of newly diagnosed cancer patients they saw, how many were asked about their smoking status and how many were identified as current smokers during each reporting period. Results from 762 participating cancer center programs were analyzed. The programs represented a diverse mix of practice sites with over 50% identified as community based. Retention in the program was high, with nearly 90% of programs completing the final survey. Most programs reported moderate organizational readiness at baseline along with an average of 4.6 implementation barriers to conducting routine smoking assessment. Barriers included factors such as lack of time, competing clinical priorities, and lack of designated tobacco treatment specialists. At baseline, the ask rate was 87.8% and this increased to 91.9% at the final survey, meeting the previously identified goal for the initiative. Throughout the initiative, programs reported increases over time in assessing smoking status, in advising patients who smoked and quit, and in documenting these assessments and recommendations in the medical record. Importantly, the smoking rate among patients asked ranged from 18.5% to 19.8% across the three surveys, demonstrating a high rate of current smoking among newly diagnosed cancer patients. The most common implementation strategies adopted by programs to promote change included gaining leadership support, improving documentation on the electronic health record, and training staff and providers. There were no major differences in implementation strategies based on program type. Organizational readiness was positively associated with better smoking assessment practices, and implementation barriers had a negative impact, although not always statistically significant. The number of implementation strategies used by programs showed a positive, significant association with smoking assessment practices at the final survey. Exploratory analyses did not suggest that program type or patient volume had a consistent relationship with the outcomes. Although the primary goal of Just ASK was smoking assessment and not cessation assistance or intervention, programs did report on cessation related practices. For example, programs reported providing education or self-help materials increased from 26% to 48%, referrals to tobacco treatment specialists increased from 25% to 35%, and referrals to quit lines increased from 27% to 45%. Prescribing or recommending FDA approved cessation medications increased from 17% to 21%. In conclusion, Just ASK is the largest nationwide initiative to standardize and improve smoking assessment in cancer care. It successfully improves smoking assessment across a diverse range of cancer practices, ensuring that hundreds of thousands of newly diagnosed cancer patients were asked about their smoking status. As nearly 20% of the cohort reported smoking, this represents a critical first step in helping patients access smoking cessation resources. Participating programs demonstrated small but sustained practice changes in smoking assessment, meeting the a priori determined goal of a 90% ask rate. However, as a quality improvement initiative, Just ASK was not designed as a clinical trial, so conclusions regarding the efficacy of the program as an intervention are limited. Selection bias may have also played a role in the findings as program participation was voluntary. Additionally, the initiative lasted just one year and while the initial improvements were steady during that time, the long term impacts of Just ASK on smoking assessment remain uncertain. Looking ahead, the American College of Surgeons recently completed the Beyond ASK initiative. This initiative is designed to go a step further and focuses on improving smoking cessation assistance and we await the results. The Just ASK initiative demonstrates the routine smoking assessment is feasible to complete as routine cancer care. This assessment is essential as identifying patients that smoke is the first and critical step towards offering smoking cessation support, which in turn can improve health outcomes and reduce cancer treatment costs. While Just ASK was a success in increasing assessment, the challenge now is ensuring that smoking cessation support is readily available for all patients who need it.

Dr. Shannon Westin and her guest, Dr. Breelyn Wilky, discuss the JCO article, "“Botensilimab (Fc-enhanced anti-cytotoxic lymphocyte-association protein-4 antibody) Plus Balstilimab (anti-PD-1 antibody) in Patients With Relapsed/Refractory Metastatic Sarcomas." TRANSCRIPT Shannon Westin: Hello, everyone, and welcome to another episode of JCO After Hours, the podcast where we get in depth on research that has been published in the Journal of Clinical Oncology. I am your host, Gynecologic Oncologist and Social Media Consultant Editor of the JCO, Shannon Westin. I serve here from the University of Texas MD Anderson Cancer Center. And I am so excited to welcome Dr. Breelyn Wilky. She's an Associate Professor and the Director of Sarcoma Medical Oncology in the Department of Medicine Division of Medical Oncology, and the Cheryl Bennett & McNeilly family endowed chair in Sarcoma Research, the Deputy Associate Director of Clinical research at the University of Colorado Cancer Center. Welcome. Dr. Breelyn Wilky: Thank you so much. I'm delighted to be here. Shannon Westin: And with all those titles, I'm super impressed that she was able to complete the manuscript that we're going to discuss today, which is “Botensilimab (Fc-enhanced anti-cytotoxic lymphocyte-association protein-4 antibody) Plus Balstilimab (anti-PD-1 antibody) in Patients With Relapsed/Refractory Metastatic Sarcomas.” And this was published in the JCO on January 27, 2025. And please note, our participants do not have any conflicts of interest. So this is exciting. Let's first level set. Can you review with us just the current state of sarcoma incidents, survival outcomes, that kind of thing so we all know where we're starting? Dr. Breelyn Wilky: Yes. So, you know, sarcomas are really, I like to call them the black box cancer type. And the big thing is that there's really more than a hundred different kinds of sarcomas, which collectively altogether make up only 1% of adult cancers. And so we talk about these as being bone and soft tissue tumors, but really, the heterogeneity is just incredible. You're talking maybe 10,000 to 12,000 new cases of soft tissue sarcoma per year, which is pretty rare in the grand scheme of things. And the trouble with these is that while you can cure sarcomas if you find them early and they're localized, when they metastasize and spread and are not resectable, we're looking at median overall survivals of really only 12 to 18 months, even, you know, with our best therapies that we have. So, really there's just a dire need for new treatments for this really tough group of diseases. Shannon Westin: Yeah, I agree. I'm a gynecologic oncologist, and we have our little subset of sarcomas that I know there's a little bit out of every one. So I'm really excited to pull this manuscript as one of our podcasts offerings because I think we're all seeing these patients in the clinic and certainly our listeners that have sarcoma or have family members with sarcoma, this is so good to have a real focus on a rare group of tumors that have been a little bit lumped together. Now, with that being said, I know this is such a heterogeneous population, but can you briefly overview a little bit around the standard of care for treatment of recurrent sarcomas? Dr. Breelyn Wilky: We have actually been using the same drugs really since about the 1970s, and up until very recently, nothing had really challenged doxorubicin, the old ‘red devil’, like we used to call it. And this has been the mainstay of treatment for metastatic sarcomas and really used across the board. In the GYN literature, for uterine leiomyosarcoma, we did see some promising activity with the combination of doxorubicin and trabectedin coming out of the French group. But, except for that study, no combination therapy or new drug has been proven better in terms of overall survival compared to doxorubicin monotherapy, really over 40, 50 years. So it's definitely a tough situation. Now, we do have other drugs that we use, so most patients will wind up getting doxorubicin-based therapy. There's a couple of other regimens that we'll reach to, like gemcitabine docetaxel. And once you get into the specific subtypes, we have some approvals in liposarcomas and leiomyosarcomas for some other drugs. But really the median progression for survival for most of these regimens is somewhere four to six months. And response rates typically are somewhere like 10%, 15% for most of these. So it's really just a very tough field and a tough group of patients to try to make an impact for. Shannon Westin: So let's talk a little bit more kind of getting focused on what you've studied here. What's been the role of immunotherapy thus far in the treatment of sarcomas maybe prior to this particular study? Dr. Breelyn Wilky: Clearly, we all know that immune therapy has just changed cancer care forever over the last few years for so many different types of cancers and diseases like melanoma and renal cell and lung cancer have just been transformed by checkpoint inhibitors specifically directed against PD-1 or CTLA-4 or both. And so, of course, you know, sarcoma docs we're super excited to try to see if these might potentially have activity in our tumors as well. I never had seen myself in my career getting into immunotherapy until I was able to run an investigator-initiated study during my role in Miami, where we combined pembrolizumab, so PD-1 inhibitor, with axitinib which was a pan-VEGF inhibitor. And lo and behold, like I had patients that I was seeing responses when other treatments, all those chemotherapies I was just talking about had failed. And one of my first patients I treated was about a 60-year-old lady with something called cutaneous angiosarcoma. So this is a blood vessel sarcoma all over her face. And we had treated her with 10 different therapies, all the chemotherapy regimens, targeted therapies, clinical trials, and nothing was working. But I put her on a phase 1 trial with a baby dose of CTLA-4 and this woman had a complete response. And so for me, once I saw it work in even just those couple of patients, like that was nothing that we'd ever seen with our chemotherapy regimens. And so that sort of shifted my career towards really focusing on this, and this is about the time where some of the studies started to come out for sarcomas. And the take home with sarcoma is about 20% of sarcomas have this sort of immune hot physiology. So what that basically means is if you look at gene expression of immune related gene signatures, or you look for infiltrating T-cells, sort of the SWAT team of our immune system, like you can find those in the tumors. And it's sort of evidence that the immune system had some clue for that 20% of patients that this was a foreign tumor and that it should be attacking it and maybe just needed a little help. But globally, about 80% of sarcomas are these immune cold tumors, which means the immune system has no clue that these things are even a threat. And there's almost no immune activation, very, very few antigens. In other cancer types, high neoantigens or tumor antigens help the immune system work better. And so that basically goes with what we've seen with trials of PD-1 or CTLA-4 blockade. About 20% of sarcomas, with some exceptions, can respond. But really 80% across the board, you're stuck, you just can't get them to be recognized. And so that's where I think this data is so interesting is there's some signals of activity in these immune cold tumors which, at least historically with the trials we've done so far, we really haven't seen that with sort of the traditional checkpoints. Shannon Westin: So I think now this is a great time to maybe talk about the study design in general, the eligibility and just give us kind of a run through of that. Dr. Breelyn Wilky: So this trial was a phase 1 trial of a drug called botensilimab, which is a next generation CTLA-4 directed immune modulator. So what makes botensilimab different is that the CTLA-4 end is very similar to other CTLA-4 inhibitors that are out there, but it's been engineered on the back end of the molecule that binds to Fc gamma receptors to basically bind tighter with higher affinity. And what this translates to in laboratory models and increasingly now in patients is it does a better job of priming, of educating our T cells, our, again, these highly intelligent antigen specific cells, but also natural killer cells. It does a better job of sort of educating those. It helps to activate macrophages and other supporting actors in the immune response. And so the idea here is that there's evidence that botensilimab may do a better job at creating new responses in immune cold tumors. The study combined either botensilimab as monotherapy or in combination with a PD-1 inhibitor called balstilimab. And this was all comers, really a variety of tumor types. And to date I think we're close to about 500 patients with a variety of solid tumors that have been accrued to this study, this C-800-01 phase 1 trial. This paper reports on the sarcoma patients that were enrolled as part of this study. And so, again, given what I've told you about sarcomas being really immune cold, we were just so excited to have the opportunity to enroll on a next generation immune therapy for these tumors that really we were running into roadblocks trying to use immunotherapy previously. Shannon Westin: It's a very compelling idea and I'm so excited for you to tell people what you found. I think first things first, it was an early phase trial. So why don't we talk a little bit about the safety of the regimen. Was there anything that you didn't expect? Dr. Breelyn Wilky: Right. So similar to other checkpoint inhibitors, you know, the idea is that these drugs can cause immune mediated toxicities, right? So essentially you're revving up the immune system and it can sometimes get a bit confused and start attacking our normal cells, our normal
In this JCO Article Insights episode, Peter Li summarizes “Neoadjuvant Modified Infusional Fluorouracil, Leucovorin, and Oxaliplatin With or Without Radiation Versus Fluorouracil Plus Radiation for Locally Advanced Rectal Cancer: Updated Results of the FOWARC Study After a Median Follow-Up of 10 Years,” by Dr. Jianwei Zhang et al. published on December 13, 2024. TRANSCRIPT Peter Li: Hello and welcome to the JCO Article Insights. I'm your host Peter Li and today we will be discussing the Journal of Clinical Oncology article, “Neoadjuvant Modified Infusional Fluorouracil, Leucovorin, and Oxaliplatin With or Without Radiation Versus Fluorouracil Plus Radiation for Locally Advanced Rectal Cancer: Updated Results of the FOWARC Study After a Median Follow-Up of 10 Years,” by Dr. Jianwei Zhang et al. For a reminder to the audience, the FOWARC study is a Chinese-based study that looked into the treatment of locally advanced rectal cancers with neoadjuvant chemotherapy based regimens with or without radiation. This study was first published back in 2019 where the three-year data showed no difference in three-year disease-free survival over survival between the three study arms. As a reminder of what those arms were, there were one historical control and two interventional arms. The control arm used 5-FU with radiation therapy with five cycles of 5-fluorouracil with radiation during cycles two to four followed by surgery and then seven cycles adjuvantly. Their first interventional arm was the same as the control arm with the addition of oxaliplatin on day 1of each cycle. And lastly, the third arm was FOLFOX only for four to six cycles followed by surgery and then six to eight cycles adjuvantly completing about a total of 12 weeks of chemotherapy. They recruited about 495 patients with 165 patients randomized to each arm. They were relatively well balanced by age, clinical staging and distance from the anal verge. Median age was about mid-50s with a slight male predominance and patients were primarily stage 3 with 20% to 30% being stage 2. About 30% had clinical T4 disease and about 25% had clinical N2 disease. Median follow up time was 122.5 months or 10 years and their follow up endpoints were disease-free survival, overall survival and local recurrence, and they also performed subgroup analyses based on post surgical pathological staging. Survival was analyzed using Kaplan-Meier method with a significant threshold of p being less than 0.05. About 451 patients actually underwent surgery, which is about 91% of patients. The main reason for not going through surgery was due to refusal but one was due to toxicity and two were due to disease progression in the control arm. Follow up loss rate was about 10% in each group. Now looking at their primary endpoints in their initial study, local recurrence was about 8.8% in the control arm versus 7.9% in the FOLFOX radiation group versus 9.2% in the FOLFOX only group. Distant metastasis was about 30% in each arm and the sites of metastases were primarily in the lung and liver. Now, following up with 10 years, there were only three new events in the chemoradiation group with local recurrence happening at 10.8% in the control arm versus 8% in the FOLFOX RT group versus 9.6% in the chemo only group. These findings were not statistically significant. In their subgroup analysis by pathological staging, they found that pathological CR or complete response had a lower rate of local recurrence compared to those with increasing pathological staging coming in at 3% versus 4.3% versus 11.6% versus 15.8% in pCR versus Stage 1, 2, 3 respectively. And they found no difference in each stage with each interventional arm. Looking at long term survival their 10-year disease free survival showed 52.5% in the 5-FU radiation group versus 62.6% in the FOLFOX RT group versus 60.5% in the chemotherapy only group with no statistically significant difference between three groups. By pathological staging, they found improved 10-year disease survival in those who achieved pathological complete response versus those who did not with 84.3% in the pCR group versus 78.7% versus 56.8% versus 27.7% in the stage 1 versus 2 versus 3 group. And again they found no statistical significance difference between each arm. Now looking at the 10-year overall survival rates between the three arms, in the control arm the 10-year overall survival was 65.9% versus 72.3% in the FOLFOX RT group versus 73.4% in the chemo only group. By pathological stage, again, they showed a statistically significant difference in those who achieved pCR versus those who had pathological stage 1 to 3 disease with overall survival being 92.4% in those who achieved pCR versus 84.9% versus 68.6% versus 48.8% in stage 1, 2, 3 respectively. Now in the discussion, authors mentioned that with a median follow up of 10 years, FOLFOX alone had similar disease-free survival, local recurrence and distant metastasis and overall survival compared to those who received neoadjuvant chemoradiation, justifying the omission of radiation without compromising results or outcomes for each patient. There were no differences in subgroup analysis for disease free survival local recurrence or overall survival based on pathological staging. There were only three new events compared to the last follow up, with local recurrence happening only in the chemo radiation groups. Local recurrence rates at 10 years was about 10%. Compared to other clinical trials such as CAO, ARO or AIO-94, the rate of local recurrence was similar to those historical trials. The authors also compared their findings to the PROSPECT study which looks at the use of total neoadjuvant chemo radiation versus chemotherapy alone, which boasted only about a 2% local recurrence rate. But as a reminder, high risk locally advanced rectal cancers were excluded, mainly those with T4 or N2 disease, which may explain the difference in terms of local recurrence in the PROSPECT versus this study. Another finding is that pathological complete responses are also an important prognostic marker with lower 10-year local recurrence rate, disease-free survival and overall survival with worse outcomes with increased pathological staging. Distant metastasis rates were still at 30%, with the most common site being lung then liver then lymph nodes consistent with other historical studies. Chemotherapy seemed to be better at reducing liver mets than lung metastasis per their findings. In their post hoc analysis of their own study, chemo radiation was also associated with higher incidence of low anterior resection syndrome and persistent ostomy compared to chemotherapy alone, meaning that they had better quality of life with the chemotherapy only approach. In conclusion, a chemotherapy only approach can be safe and a feasible treatment for locally advanced rectal cancer without compromising outcomes. Omission of radiation may reduce the risk of overtreatment and improve quality of life for some of these patients. However, this does not necessarily exclude the role of radiation as it may still play a role in a response escalation approach for those who do not respond to chemotherapy alone.

Host Dr. Shannon Westin and guests Dr. Bill Aronson discuss the article "High Omega-3, Low Omega-6 Diet With Fish Oil for Men With Prostate Cancer on Active Surveillance: The CAPFISH-3 Randomized Clinical Trial" and how Omega-6 are predominant in the American diet while the study significantly lowered the intake of Omega- 6 fats. TRANSCRIPT Dr. Shannon Westin: Hello everyone and welcome to another episode of JCO After Hours, the podcast where we get in depth on manuscripts published in the Journal of Clinical Oncology. I'm your host, Dr. Shannon Westin, GYN Oncologist by trade and one of the grateful Social Media Editors of the JCO. And I am very excited to welcome a special guest today, Dr. William Aronson. He is professor of Urology in the UCLA Department of Urology, the Chief of Urology at Olive View UCLA Medical Center, and Chief of Urologic Oncology at the Veterans Administration West Los Angeles. Welcome, Dr. Aronson. Dr. William Aronson: Thank you, Shannon, and delighted to be here. Dr. Shannon Westin: We are so excited to have you discussing your manuscript, “High Omega-3, Low Omega-6 Diet With Fish Oil for Men With Prostate Cancer on Active Surveillance: The CAPFISH-3 Randomized Clinical Trial,” which was published in the Journal of Clinical Oncology on December 13, 2024. So let's get right to it. First of all, you know we have a very mixed audience, so can you just level set for us and speak about the population you studied in this important trial - that low risk, favorable, intermediate risk prostate cancer. How common is that? How is it defined? That would really help. Dr. William Aronson: I would say about 50% of the patients that we diagnose with prostate cancer either have low risk disease or what we call favorable intermediate risk disease. So when the pathologists look at the cancer under the microscope, they assign what's called a Gleason grade. Grade 3 is the slower growing type of prostate cancer, grade 5 is the fastest growing type, and grade 4 is somewhere in between. So a low risk group would be only the grade 3, the slower growing type. And the favorable intermediate risk group would actually be the grade 3+4, which means they mostly see the low risk type in there, but they also see the slightly faster growing type, grade 4. So this is what we typically see. We see these patients on a very regular basis when they're newly diagnosed with prostate cancer. Dr. Shannon Westin: Okay, got it. And then can you walk us through just what the management options are typically for this patient population? Dr. William Aronson: So typically for what we call the low risk group, the patients with a low PSA and only that grade 3 type, slower growing type of prostate cancer, the standard recommendations are active surveillance. So typically, we'll periodically monitor these patients with PSA blood testing and periodically do prostate biopsies depending upon the patient's other medical problems. Dr. Shannon Westin: So I think it would also be really helpful just to understand what your typical management options are for this patient population. Dr. William Aronson: So for patients with low risk prostate cancer, they only have the Gleason Grade 3+3 with a low PSA. The standard practice is observation. And so these men will periodically see them and measure their PSA values. And periodically, they'll undergo prostate biopsy to make sure they're not getting progression of their disease. For men with favorable intermediate risk prostate cancer, that's a little different. In some practices, the patient and the urologist will decide to do active surveillance. In other scenarios, these patients will definitely elect treatment, either with radical prostatectomy or radiation therapy or other treatments that are available. Dr. Shannon Westin: So your manuscript notes that there was a high level of interest in dietary supplements and approaches among patients with prostate cancer that do elect for active surveillance. Prior to the results of CAPFISH-3, did we have any data to support those types of recommendations? Dr. William Aronson: We actually don't have any long term prospective randomized trials that support that recommendation. There have been a number of very interesting epidemiologic studies, for example, suggesting maybe a plant-based diet might be helpful. Or a number of other studies suggesting maybe more tomato-based products like tomato sauces or tomato paste may be helpful. But no prospective longer term randomized trials that were positive. Dr. Shannon Westin: Okay, that makes sense. So what led you all to explore the high omega-3, low omega-6 fatty acid diet in this trial? Dr. William Aronson: After our initial omega-6 studies, we subsequently did some studies where we raised the omega-3 from fish oil and lowered the 6, looking at a more favorable ratio of the omega-3 to omega-6. And once again, we found that in our animal models, there was a significant delay in progression of prostate cancer. That then led us to perform a clinical trial. It was a short term trial in men prior to undergoing radical prostatectomy. And in these men, they were randomly assigned to one of two groups, either a western high fat diet or a low fat diet with fish oil. And we found after just four to six weeks, a significant change in the Ki67 level in their radical prostatectomy tissue. And Ki67 is actually a strong indicator of prostate cancer progression, spread, or even death from prostate cancer. Dr. Shannon Westin: Well, and I think that leads us really nicely into the design of the current study. So why don't you walk us through how CAPFISH-3 was designed. And you've already spoken a little bit about your primary endpoint. Dr. William Aronson: Based on the results of what we saw in the lab and what we saw in our short term clinical trial, we decided to perform a one year trial, a longer term trial in men on active surveillance. And these men were randomly assigned to either a diet with slight reduction in dietary fat, specifically reduction in the omega-6 intake as well as increase in foods with omega-3 and fish oil capsules. The other group, we asked the men to just not take fish oil capsules, but they could eat whatever else they wanted during the course of the study. Men in the diet where we lowered the omega-6 and raised the omega-3, they were seen by a dietitian once a month to really ensure that they were compliant with that intervention, which they were. The other intriguing part of our study, which I think is super important, is the precision that was used when these men underwent prostate biopsy. So, at baseline and at one year, when these men underwent prostate biopsy, they had the same site within the prostate biopsied. That's important because it's not so easy to find the same site within the prostate because of heterogeneity throughout the prostate. And so we were able to obtain that high level of precision as they were in an active surveillance program at UCLA with Dr. Leonard Marks. Dr. Shannon Westin: So we spoke a little bit about what's important about the Ki67 index as your primary endpoint. Can you talk a little bit about what the study found with your intervention? Dr. William Aronson: So we found that the Ki67 index increased by 24% in the control group and decreased by 15% in the low omega-6, high omega-3 group with fish oil capsules. So that ended up resulting in a statistically significant change between the groups favoring the low omega-6, high omega-3 group. Dr. Shannon Westin: And then what were the secondary endpoints that CAPFISH-3 explored? Anything of note that you want to review for the listeners? Dr. William Aronson: So a number of positive secondary endpoints from the trial. Firstly, we saw that the triglyceride levels were lower, which is what can typically be seen with omega-3 intake. We also saw reduced levels of a cytokine, a circulating factor in the bloodstream called ‘macrophage colony stimulating factor’. And that's particularly interesting because there's a certain type of macrophage which is well known to be involved in prostate cancer progression in men with more advanced prostate cancer, and we've been able to inhibit that in our animal models and in our tissue culture studies. And it was especially interesting to see that we did have an effect on this particular cytokine in this prospective randomized trial. We did not see changes in a number of other measures, including Gleason grade or PSA. These are measures that we use in clinical practice. To see an effect on those would have required a longer term and larger study to be performed. Dr. Shannon Westin: That makes sense. I think it's always great to try to get as much of these types of translational data as we can. But sometimes you just have to do what is reasonable and you get what you get. It looks to me like this regimen was fairly well tolerated. Did you obtain any patient reported outcomes or feedback on the trial? Dr. William Aronson: So, there were four patients in the fish oil group that did have some side effects, and we withdrew them from the study. They did have some effects on their upset stomach, and a number of men also had some diarrhea as well. And so for those four patients, we did withdraw them from the study. Dr. Shannon Westin: And then I guess the last question I have is really, what's next for this intervention? Are we ready to move this to the clinic or what do you see as next steps? Dr. William Aronson: Well, this next step that we're working on right now is to better understand exactly what happened in these patients. So we have blood, we have tissue, we're doing genetic studies on these patients. So that's really the first step, in our mind, to better understand what happened before moving to the next step. I'm particularly intrigued about trying this intervention in men with more advanced prostate cancer, specifically because of what we see, this particular diet and
In this JCO Article Insights episode, Ece Cali summarizes findings from the JCO article, "Datopotamab Deruxtecan Versus Docetaxel for Previously Treated Advanced or Metastatic Non–Small Cell Lung Cancer: The Randomized, Open-Label Phase III TROPION-Lung01 Study." TRANSCRIPT Ece Cali: Hello and welcome to the JCO Article Insights. I'm your host Ece Cali and today we will be discussing the Journal of Clinical Oncology article the “Datopotamab Deruxtecan Versus Docetaxel for Previously Treated Advanced or Metastatic Non–Small Cell Lung Cancer: The Randomized, Open-Label Phase III TROPION-Lung01 Study.” Despite significant advances in non-small cell lung cancer treatment over the past decades, second line treatment options for non-small cell lung cancer without actionable genomic alterations have remained largely unchanged since 2000. Many clinical trials failed to demonstrate improved overall survival compared to docetaxel based regimens. TROPION-Lung01 is a global open label randomized phase 3 trial comparing the efficacy and safety of Dato-DXd to docetaxel in patients with previously treated advanced or metastatic non-small cell lung cancer. Dato-DXd is an antibody drug conjugate targeting TROP2 and delivering deruxtecan, a DNA topoisomerase 1 inhibitor, as its payload. The trial is designed with dual primary endpoints of progression free survival, as assessed by blinded independent central review, and overall survival. The initial PFS results were presented at ESMO in 2023 and this article reports more detailed data and overall survival analysis of the trial. In the TROPION-Lung01, 299 patients were randomly assigned to receive Dato-DXd and 305 patients to receive docetaxel. Patients were stratified by the presence of actionable genomic alterations, histology, treatment with PD-1/PD-L1 immunotherapy as the last line of therapy, and geographical region. The baseline characteristics of the patient population were overall balanced between the treatment arms. I'd like to highlight a couple of key points here. The median age was 63 years in the Dato-DXd and 64 years in the docetaxel arm. Similar to the many clinical trials in the thoracic oncology field, this is younger than the median age of lung cancer diagnosis in the US, which is around 70. African American and Hispanic patients were underrepresented in this trial with 41% of patients identifying themselves as white and 39% as Asian. The D\docetaxel arm had a slightly higher percentage of male patients, 69% versus 61%. The majority of the trial population, 73%, had adenocarcinoma. Patients with actionable genomic alterations were included in this trial if they received one or more targeted therapy and platinum based chemotherapy prior to the enrollment. 17% of the trial population had an actionable genomic alteration in this trial. When it comes to the efficacy results in the full analysis set, the PFS improvement was statistically significant. The median PFS was reported as 4.4 months for the Dato-DXd, and 3.7 months for the docetaxel arm with the hazard ratio of 0.75 and a P value of 0.004. However, after a median follow up of 23 months, the trial did not meet its primary endpoint of overall survival. The median overall survival was 12.9 months for patients treated with Dato-DXd and 11.8 months for patients treated with docetaxel with the hazard ratio of 0.94 and a P value of 0.53. Objective response was a secondary endpoint and the confirmed objective response rate was 26% with Dato-DXd, and 13% with docetaxel. Now let's take a closer look at some of the subgroup analyses. Exploratory analyses of key subgroups in TROPION-Lung01 demonstrated differences in efficacy based on histology. In the nonsquamous subgroup, Dato-DXd showed a longer progression free survival of 5.5 months compared to 3.6 months with docetaxel with a hazard ratio of 0.84. However, in the squamous subgroup, Dato-DXd performed worse with a progression free survival of 2.8 months compared to 3.9 months with docetaxel corresponding to a hazard ratio of 1.32. A similar trend was observed in the overall survival analyses, though confidence intervals crossed 1 in both histology subsets, in this case, the differences observed were not statistically significant. In the nonsquamous subset, the median overall survival was 14.6 months with Dato-DXd and 12.3 months with docetaxel with a hazard ratio of 0.84. In the squamous subset, both arms had shorter survival compared to the nonsquamous subset. The median overall survival with Dato-DXd was almost two months shorter, so 7.6 months, compared to 9.6 months with docetaxel corresponding to a hazard ratio of 1.32. While these analyses suggest the potential survival benefit for Dato-DXd in nonsquamous subset, this trial was not powered to test this hypothesis hence these analyses remain exploratory. Another subgroup analysis of note was the group with actionable genomic alterations. Patients with actionable genomic alterations achieved a median PFS of 5.7 months with Dato-DXD and 2.6 months with docetaxel corresponding to a hazard ratio of 0.35. Similarly, the median overall survival was longer in patients with actionable genomic alterations by almost six months, with a median overall survival of 15.6 months with Dato-DXd and 9.8 months with docetaxel corresponding to a hazard ratio of 0.65. Now, let's talk about safety. Grade 3 or higher treatment related adverse events occurred in 26% of patients with Dato-DXd and 42% with docetaxel. The most common adverse event of any grade seen in the Dato-DXd arm were stomatitis seen in 47% of patients, nausea in 34%, and alopecia in 32%. Treatment related interstitial lung disease occurred in 8.8% of patients on Dato-DXd and 4.1% of patients on docetaxel. Of note, grade 5 drug related ILD was more frequent with Dato-DXd. Seven patients on Dato-DXd and one patient on docetaxel died secondary to drug related ILD in this trial. In summary, TROPION-Lung01 aims to address an unmet need for patients with previously treated non-small cell lung cancer. For this population, the treatment options remain limited with poor survival outcomes. TROPION-Lung01 is a positive trial by design due to clinically modest improvement in PFS. However, the lack of overall survival improvement is disappointing. Exploratory subgroup analyses suggest Dato-DXd may offer survival advantage in specific subsets such as nonsquamous non-small cell lung cancer and patients with actionable genomic alterations. However, these findings require further validation in a prospective trial since TROPION-Lung01 was not designed to address these questions. The data from this trial alone is not sufficient to argue for a change in clinical practice. However, it informs how the future trials using this drug should be tailored. This highlights the importance of studying potential predictive biomarkers earlier in the drug development and incorporating these biomarkers prospectively into the clinical trial designs. Due to the lack of overall survival benefit in this trial, the biologic license application for accelerated approval of Dato-DXd for patients with previously treated nonsquamous non-small cell lung cancer was voluntarily withdrawn. New BLA was submitted for Dato-DXd for patients with previously treated advanced EGFR positive non-small cell lung cancer. This BLA is based on data from TROPION-Lung05, TROPION-Lung01 and TROPION-PanTumor01. Of note, the results of TROPION-Lung05 trial have been just published in JCO. This wraps up today's episode.
