TRANSCRIPT
Dr. Vamsi Velcheti: Hello, I am Dr. Vamsi Velcheti, your guest host for the ASCO Daily News Podcast today. I'm a professor of medicine and director of thoracic medical oncology at the Perlmutter Cancer Center at NYU Langone Health. Today, I'm joined by Dr. Nate Pennell, the co-director of the Cleveland Clinic Lung Cancer Program and the vice chair of clinical research at the Taussig Cancer Center in Cleveland Clinic. Dr. Pennell is also the editor-in-chief of the ASCO Educational Book. Today, we will be discussing practice-changing abstracts and the exciting advances in lung cancer that were featured at the ASCO 2024 Annual Meeting.
You'll find our full disclosures in the transcript of the episode.
Nate, we're delighted to have you back on the podcast today. Thanks for being here. It was an exciting Annual Meeting with a lot of important updates in lung cancer.
Dr. Nate Pennell: Thanks, Vamsi. I'm glad to be back. And yes, it was a huge year for lung. So I'm glad that we got a chance to discuss all of these late-breaking abstracts that we didn't get to talk about during the prelim podcast.
Dr. Vamsi Velcheti: Let's dive in. Nate, it was wonderful to see all the exciting data, and one of the abstracts in the Plenary Session caught my attention, LBA3. In this study, the investigators did a comparative large-scale effectiveness trial of early palliative care delivered via telehealth versus in-person among patients with advanced non-small cell lung cancer. And the study is very promising. Could you tell us a little bit more about the study and your take-home messages?
Dr. Nate Pennell: Yes, I think this was a very important study. So just to put things in perspective, it's now been more than a decade since Dr. Jennifer Temel and her group at Massachusetts General Hospital did a randomized study that showed that early interventions with palliative medicine consultation in patients with advanced non-small cell lung cancer significantly improves quality of life and in her initial study, perhaps even overall survival. And since then, there have been numerous studies that have basically reproduced this effect, showing that getting palliative medicine involved in people with advanced cancer, multiple different cancer types, really, has benefits. 
The difficulty in applying this has been that palliative care-trained specialists are few and far between, and many people simply don't have easy access to palliative medicine-trained physicians and providers. So with that in mind, Dr. Temel and her group designed a randomized study called the REACH PC trial, where 1,250 patients were randomized with advanced non-small cell lung cancer to either in-person palliative medicine visits which is sort of the standard, or one in-person assessment followed by monthly telemedicine video visits with palliative medicine. Primary endpoint was essentially to show that it was equivalent in terms of quality of life and patient satisfaction. And what was exciting about this was that it absolutely was. I mean, pretty much across the board in all the metrics that were measured, the quality-of-life, the patient satisfaction, the anxiety and depression scores, all were equivalent between doing telemedicine visits and in-person visits. And this hopefully will now extend the ability to get this kind of benefit to a much larger group of people who don't have to geographically be located near a palliative medicine program.
Dr. Vamsi Velcheti: Yeah, I think it's a great abstract, Nate and I actually was very impressed by the ASCO committee for selecting this for the Plenary. We typically don't see supportive care studies highlighted in such a way at ASCO. This really highlights the need for true interdisciplinary care for our patients.

Dr. Shaalan Beg highlights practice-changing studies in GI cancers featured at the 2024 ASCO Annual Meeting, including the ESOPEC trial in esophageal adenocarcinoma and durable responses to PD-1 blockade alone in mismatch repair-deficient locally advanced rectal cancer.

Geraldine Carroll: Welcome to the ASCO Daily News Podcast. I'm Geraldine Carroll, a reporter for the ASCO Daily News. My guest today is Dr. Shaalan Beg, an adjunct associate professor at UT Southwestern Simmons Comprehensive Cancer Center. Dr. Beg will be discussing practice- changing abstracts and other key advances in GI oncology that were presented at the 2024 ASCO Annual Meeting. His full disclosures are available in the transcript of this episode. 
Dr. Beg, thanks for being on the podcast today. 
Dr. Shaalan Beg: Thank you for having me.
Geraldine Carroll: Let's begin with LBA1, the ESOPEC trial. This was featured in the Plenary Session, and this study compared two treatment strategies for locally advanced esophageal adenocarcinoma that could be treated with surgery. The strategies include the CROSS protocol, which consisted of chemoradiotherapy before surgery, and the FLOT protocol of chemotherapy before and after surgery. Can you tell us about this practice-changing study, Dr. Beg?
Dr. Shaalan Beg: Yes. According to this study, perioperative chemotherapy with FLOT was better than neoadjuvant therapy with chemoradiation and carbo-taxol for people with adenocarcinoma of the esophagus. There were 438 patients enrolled on this phase 3 study. R0 resection rates were fairly similar across both groups. The PCR rates were a little higher on the FLOT group. But when you look at the median overall survival difference, 66 months in the FLOT group versus 37 months in the CROSS group, 3-year survival was 57% versus 50% favoring FLOT therapy as well. 
So a couple of caveats on this clinical trial, because the first thing to note is that the standard treatment for this disease has evolved because we now don't only give CROSS chemoradiation, we also give immunotherapy after the completion of chemoradiation for this group of patients. And in this study, since it predated that standard of care, patients did not receive immunotherapy. But having said that, the take home for me here is that chemotherapy is better than chemoradiation for this group of patients, recognizing the fact that 1) they only enrolled adenocarcinoma patients, and 2) patients with high T stage were not included. So the folks with high T stage would be those who we would expect would benefit from the radiation aspect. So my take home here is that more chemotherapy is better in the perioperative space. Radiation should be considered for individuals who need more local control. But in general, I think we're going to see us moving more towards chemotherapy-based regimens with FLOT for this group of patients.
Geraldine Carroll: Great. So moving on to rectal cancer, in LBA3512, investigators reported durable, complete responses to PD-1 blockade alone in mismatch repair deficient locally advanced rectal cancer. Can you tell us more about the promising durable responses that occurred in this trial? 
Dr. Shaalan Beg: On first glance, seeing that immunotherapy has good activity in patients with mismatched repair deficient rectal cancer isn't really headline breaking news anymore. We've known about this activity for this group of patients for many years. Earlier at ASCO, the investigators presented early results of this compound for people receiving six months of dostarlimab therapy for people with mismatched repair deficient, locally advanced rectal cancer, and showed that they had a very high complete response rate. At that time, it generated a lot of interest and there was a lot of curiosity on whether these outcomes will be sustained. We don't know other characteristics of their biologic status and whether this was some sort of reflection of the patients who are selected o

Dr. Diwakar Davar and Dr. Jason Luke discuss advances in the neoadjuvant immunotherapy space that were presented at the 2024 ASCO Annual Meeting, including promising outcomes in high-risk melanoma from the NADINA trial, as well as other new treatment options for patients with advanced cancers.

Dr. Diwakar Davar: Hello and welcome to the ASCO Daily News Podcast. I'm your guest host, Dr. Diwakar Davar, and I am an associate professor of medicine and the clinical director of the Melanoma Skin Cancer Program at the University of Pittsburgh's Hillman Cancer Center. I am delighted to have my colleague and friend Dr. Jason Luke on the podcast today to discuss key late-breaking abstracts and advances in immunotherapy that were presented at the 2024 ASCO Annual Meeting. Dr. Luke is an associate professor of medicine, the associate director of clinical research, and the director of the Cancer Immunotherapeutic Center at the University of Pittsburgh Hillman Cancer Center.  
You will find our full disclosures in the transcript of this episode. 
Jason, it's always a pleasure to hear your insights on the key trials in these spaces and to have you back as a guest on this podcast that highlights some of the work, especially advances, that were just presented.
Dr. Jason Luke: Well, thanks very much for the invitation. I always love joining the podcast.
Dr. Diwakar Davar: We'll start very quickly by talking about some advances and really interesting things that happened both in the context of melanoma but also in immunotherapy in general. And we'll start with what I think was certainly one highlight for me, which was LBA2, the late-breaking abstract on the NADINA trial. It was featured in the Plenary Session, and in this abstract, Dr. Christian Blank and colleagues reported on the results of this phase 3 trial of neoadjuvant ipi-nivo. This is the flipped dose of ipi1/nivo3 versus adjuvant nivolumab in PD-1 naive, macroscopic, resectable, high-risk stage 3 melanoma. 
By way of background, neoadjuvant immunotherapy for those listening is an area of increasing interest for drug developers and development for both approved and novel agents. Neoadjuvant immunotherapy has been studied with multiple approved agents, including PD-1 monotherapy, PD-1 LAG-3, PD-1 CTLA-4, T-VEC, as well as investigational agents and multiple randomized and non-randomized studies. The benchmark pathologic response rates with these agents range from 17% PCR with PD-1 monotherapy, 45% to 55% PCR with PD-1 CTLA-4 combination therapy, and slightly higher 57% PCR with PD-1 LAG-3 has recently reported by Dr. Rodabe Amaria from MD Anderson. However, as we embark on phase 3 comparisons for various neoadjuvant compared to adjuvant immunotherapy trials and combinations, we're increasingly moving towards event-free survival as the primary endpoint for neoadjuvant versus adjuvant studies. And this was most recently studied in the context of SWOG S1801, a study that was led by Dr. Sapna Patel. 
So, Jason, before we start on NADINA, can you briefly summarize the SWOG S1801 trial and the event-free survival statistic reported by Dr. Patel and her colleagues?
Dr. Jason Luke: Well, absolutely. And these data were reported at ESMO about two years ago and then in the New England Journal last year. The S1801 study answered a very simple question: What would happen if you took three of the doses of standard adjuvant therapy with pembrolizumab and moved them prior to surgery? And on a high level, the study is as simple as that. And many of us were somewhat skeptical of this trial design because we thought that just moving the doses earlier may not actually have a major impact. 
In the study, you alluded to the event-free survival statistic, and that alludes to what was considered an event. And so, without reading all of it, there were several different aspects that were included in terms of time, based on the date of randomization until the

Dr. John Sweetenham shares highlights from Day 4 of the 2024 ASCO Annual Meeting, including exciting new data from the IMROZ trial in multiple myeloma, adjuvant therapy for triple-negative breast cancer in A-BRAVE, and the front-line treatment of advanced renal cell carcinoma in JAVELIN Renal-101.

Dr. John Sweetenham: I'm Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my top takeaways on selected abstracts from Day 4 of the 2024 ASCO Annual Meeting.  
Today's selection features 3 randomized prospective trials in the first-line treatment of multiple myeloma, adjuvant therapy for triple negative breast cancer, and the frontline treatment of advanced renal cell carcinoma, all of which provide important new data.  
My full disclosures are available in the transcript of this episode.
The first of today's abstracts is number 7500. This abstract, presented by Dr. Thierry Facon from the Department of Hematology at the University of Lille in France, describes the results of the IMROZ study. This was a multicenter phase 3 study comparing a current standard first-line regimen for transplant ineligible patients with myeloma VRd with the same combination plus an additional agent, isatuximab. 
The combination of bortezomib, lenalidomide and dexamethasone, known as VRd, is currently a standard first-line regimen for patients with multiple myeloma, both transplant eligible and ineligible. Previous phase 3 studies have shown that the addition of an anti-CD38 antibody to triplet regimens improves outcomes in newly diagnosed patients. Based on early phase clinical trial data showing promising response rates with isatuximab, the IMROZ study was conducted to compare isatuximab VRd with VRd alone in patients who were either ineligible for transplant or had no immediate indication for transplant.
IMROZ was a global study conducted in 21 countries that involved 446 patients randomly assigned 3:2 to induction therapy with Isa-VRd followed by continuous Isa-Rd or induction therapy with VRd followed by Rd alone. The rate of complete response or better was approximately 75% with Isa-VRd compared with 64% with VRd alone. Very good partial response or better was achieved in 89% of patients with Isa-VRd, compared with around 83% of those with VRd alone. With a median follow-up at 5 years, Isa-VRd followed by Isa-Rd had reduced the risk of progression or death by 40.4% compared with VRd alone. The 60-month progression-free survival rate was 63% for Isa-VRd compared with around 45% with VRd alone, and the progression-free survival benefit was maintained in most of the analyzed subgroups. Minimal residual disease negativity was also measured in this study in both the intent to treat population and those patients who achieved a complete response. For example, in the intent to treat population, the MRD negative rate was 58% with Isa-VRd compared with around 43% with VRd alone.
There were also higher rates of sustained MRD negativity for 12 months or longer among patients assigned to Isa-VRd compared with VRd alone, reflecting deeper responses in the Isa-VRd arm. Although overall survival data is still immature, data from an interim analysis showed a favorable trend in the Isa-VRd arm with 22.4% risk reduction compared with VRd alone. There was little additional toxicity from the inclusion of isatuximab with the VRd regimen and the quality-of-life data were comparable and stable in both arms of the study. The investigators concluded that although overall survival data are immature, there is a trend in favor of Isa-VRd and this, combined with the favorable response, toxicity and progression-free survival data, establish isatuximab VRd as a potential new standard of care for newly diagnosed multiple myeloma patients not eligible for transplant. There was some discussion regarding the potential use of this regimen in patients over 80 years of age since the upper age limit was capped in IMROZ at 80 years. Althoug

Dr. John Sweetenham shares highlights from Day 3 of the 2024 ASCO Annual Meeting, including selected studies on the treatment of cancer cachexia, surgical approaches in advanced ovarian cancer, and advanced colorectal cancer with liver metastases.

Dr. John Sweetenham: I'm Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my top takeaways on selected abstracts from Day 3 of the 2024 ASCO Annual Meeting. 
Today's selection features studies addressing the treatment of cancer cachexia and 2 studies of surgical approaches to the treatment of advanced ovarian cancer and of advanced colorectal cancer with liver metastases.

Cachexia affects up to 80% of patients with advanced cancer and is thought to be directly responsible for 30% of cancer deaths, according to the National Cancer Institute. Despite these statistics, the condition remains understudied and there is no standard treatment. Current guidelines recommend dietary counseling and low-dose olanzapine or short courses of corticosteroids or progesterone analogues can be used to promote weight gain. However, the guidelines mainly point to evidence gaps. No drug therapy could be strongly endorsed to improve patient outcomes and no recommendations could be made regarding exercise. 
Dr. Tora Solheim from the Cancer Clinic at St. Olavs Hospital in Trondheim, Norway, today reported results from the MENAC trial in LBA12007, which tested an intervention that combined treatment with nonsteroidal anti-inflammatory medication ibuprofen, home-based exercise to improve endurance and muscle strength, nutritional counseling, and supplements containing omega-3 fatty acids, which, based on previous research, may enhance muscle mass in patients with cancer cachexia. This trial enrolled 212 patients with stage III or IV lung or pancreatic cancer from 17 sites in 5 countries. All patients were receiving palliative chemotherapy and either had cachexia or were at high risk of developing it. Half were randomly assigned to the intervention and half to standard care. For the exercise components of the intervention, patients were encouraged to engage in aerobic activity such as walking, swimming, or even household chores at least twice a week. They were also encouraged to perform strengthening exercises such as half squats, bicep curls, and knee lifts 3 times per week. 
Over 6 weeks, the trial found average body weight stabilized in the intervention group compared with a loss of 1 kg in the standard care group, but there were no differences between the two groups and the secondary endpoints of muscle mass and daily step count as measured by ActiGraph. Dr. Solheim pointed out that 6 to 8 weeks may be too early to observe any anabolic effects on muscle mass or function, but that this timeframe was chosen, she said, because previous studies, including her team’s own feasibility study had encountered high dropout rates among similar patient groups after 6 to 8 weeks. 
Although these are interesting data, I think they also pose many questions: Is maintaining 1 kg of body weight a meaningful endpoint? Did the patients report any improvement in other symptoms? How was at-home exercise monitored for compliance? Did we know whether the patients were fulfilling adequate amounts of exercise? And there are many more questions. I think the investigators should be congratulated for demonstrating the feasibility of conducting a randomized trial in this challenging patient group, and this will hopefully provide a basis for future studies exploring new interventions.
In LBA5505, Dr. Jean-Marc Classe presented data from the CARACO study, a randomized trial evaluating the use of retroperitoneal lymph node dissection in patients undergoing primary surgery or interval cytoreductive surgery after neoadjuvant chemotherapy for advanced epithelial ovarian cancer.  
To provide some context, an earl

Dr. John Sweetenham shares highlights from Day 2 of the 2024 ASCO Annual Meeting, including potentially practice-changing results in advanced Hodgkin lymphoma, intriguing data on the effect of metformin on active surveillance for prostate cancer, and the potential of AI to improve patient outreach and adherence to medical appointments.

Dr. John Sweetenham: I'm Dr. John Sweetenham, the host of the ASCO Daily News Podcast, with my top takeaways on selected abstracts from Day 2 of the 2024 ASCO Annual Meeting.  

Today's selection features potentially practice-changing results for patients with advanced stage Hodgkin lymphoma, results from a large trial testing the effects of metformin in patients on active surveillance for their prostate cancer, and early results giving insights into the benefits that artificial intelligence may bring to address disparities in cancer care.   

My full disclosures are available in the transcript of this episode.  

The first of today's abstracts is LBA7000, which reports the results from a large international randomized trial in patients with advanced Hodgkin lymphoma, presented by Dr. Peter Borchmann from the German Hodgkin Study Group. Since Hodgkin lymphoma typically affects adults in their 20s and 30s, the focus of clinical trials in recent years has been on achieving high rates of disease control while at the same time reducing the potential for short-term and long-term toxicities associated with classical chemotherapy and radiation therapy regimens. Particular emphasis has been given to reducing risk for secondary malignancy and impaired reproductive function in long-term survivors.  

Building on the back of previous studies from this group, the escalated BEACOPP regimen was modified to reduce the overall duration of treatment and the potential for toxicity by incorporating novel agents, including brentuximab vedotin. This novel regimen, known as BrECADD, was compared with escalated BEACOPP in a randomized trial, HD21. Patients received 4 or 6 cycles of therapy based on the response of their disease to the first 2 cycles assessed by interim PET scan. 1,482 patients were randomized, 740 to escalated BEACOPP and 742 to BrECADD, with median follow-up at 48 months. The 4-year progression-free survival was 94.3% with BrECADD, compared with 90.9% for escalated BEACOPP, with a hazard ratio of 0.66. These results are particularly noteworthy since 64% of patients on the BrECADD arm had a negative PET scan after 2 cycles of therapy and therefore received a total of just 4 cycles, reducing their risk of toxicity.   

On that note, lower rates of treatment related toxicity were observed with BrECADD. Specifically, hematologic toxicity and peripheral sensory neuropathy were less frequently seen. Female reproductive toxicity was lower with BrECADD, with more than 95% of women having normal FSH levels after 1 year on BrECADD, compared with 73% on escalated BEACOPP. Dr. Borchmann also noted that recovery of male reproductive function was improved with BrECADD, although details were not provided. These are impressive data, although no overall survival difference was observed. This is not surprising in view of the effective salvage therapies available to patients whose disease relapses after first-line therapy.  

The authors conclude that these results are unprecedented for the first-line treatment of Hodgkin lymphoma and that the BrECADD regimen should be considered as a new standard of care option. Although these results are likely to change practice in some parts of the world, particularly in Europe, it's less clear whether they will impact current treatments in the United States, where modifications to the ABVD regimen, including the addition of brentuximab vedotin and more recently nivolumab, have been the subject of recent randomized trials. That said, these data add to the increasing evidence that cure of advanced Hodgkin lymphoma is possible in m
