Drs. John Sweetenham and Marc Braunstein discuss advances in hematologic malignancies featured at the 2023 ASCO Annual Meeting, including the potentially practice-changing SWOG-S1826 study in Hodgkin lymphoma, the promise of bispecific antibodies in B-cell malignancies, and a novel approach to deliver vital anti-myeloma medications that could improve patient quality of life and alleviate barriers to care. TRANSCRIPT   Dr. John Sweetenham: Hello, I'm John Sweetenham, the associate director for cancer network clinical affairs at UT Southwestern's Harold C. Simmons Comprehensive Cancer Center and the host of the ASCO Daily News Podcast.    The 2023 ASCO Annual Meeting featured some exciting new data on hematologic malignancies. I'm delighted to have Dr. Marc Braunstein return to the podcast to discuss some of these potentially practice-changing studies and new approaches in the heme space. Dr. Braunstein is a hematologist and oncologist at the NYU Perlmutter Cancer Center.    You'll find our full disclosures in the transcript of this episode, and disclosures of all guests on the ASCO Daily News Podcast are available on our transcripts at asco.org/DNpod.   Marc, it’s great to have you back on the podcast, and thanks for being here again.   Dr. Marc Braunstein: Thank you, John. It's great to be back.   Dr. John Sweetenham: Marc, we already mentioned that there are some potentially practice-changing studies that were reported at ASCO this year. And among those, LBA4, which was presented in the Plenary Session, was a study which explored the treatment of advanced Hodgkin lymphoma. This was the Southwest Oncology Group study S1826. Could you give us your insights on this?    Dr. Marc Braunstein: Sure, happy to discuss S1826. So as background, you know, the ECHELON-1 study, which was published in the New England Journal of Medicine in 2022 showed a 40% decrease in the risk of death at six years follow-up by adding brentuximab to AVD compared to bleomycin AVD. And that was in high risk or advanced-stage patients and that led to adoption of brentuximab for upfront use in patients with classical Hodgkin lymphoma in advanced stage.    Also of note, immune checkpoint inhibitors such as pembrolizumab or nivolumab do have activity in the relapse setting. The SWOG S1826 study was a randomized control study looking at the use of the PD-1 inhibitor nivolumab plus AVD versus brentuximab AVD in patients with advanced stage classical Hodgkin lymphoma who are at least twelve years of age. And the primary endpoint in the study was progression-free survival.     It was a large study which enrolled 976 patients and randomized them one to one to either nivo AVD or brentuximab AVD. The median age in the study was 27 and the median follow-up was 12 months. And what the study found, which could be practice-changing, was that the primary endpoint of progression-free survival was superior in the nivolumab arm with a hazard ratio of 0.8 and a one-year PFS of 94% versus 86%, favoring the nivolumab arm. And while there were side effects associated with the class of medications, for example, hypo or hyperthyroidism was more frequent in the nivolumab group, whereas peripheral neuropathy was higher in the brentuximab group, I think that these results are particularly encouraging for how we can continue to improve outcomes for patients with advanced-stage classical Hodgkin lymphoma. And this may be practice-changing in terms of whether we use upfront immune checkpoint inhibitors in combination with our standard chemotherapy backbone.    Dr. John Sweetenham: Yeah, absolutely. There are a couple of things that occur to me. One in particular which is unique about this study, and the fact that it was for patients who are 12 years and older in many respects represents a first because I can't think of another large, randomized study of this type which has attempted to align pediatric and adult c
