Guest Mohamad Mohty discusses updates on BCMA-targeting bispecific antibodies for multiple myeloma from EHA & ASCO 2024. Topics include MagnetisMM-3 trial data on elranatamab, real-world findings, step-up dosing of teclistamab, MAIC comparison of linvoseltamab with teclistamab, and sequencing of bispecific antibodies with CAR T-cells.
Renatumab shows promising results in treating relapsed/refractory multiple myeloma, indicating a valuable salvage treatment option.
Utilizing step-up dosing for Teclistumab in real-world settings can optimize patient experience and reduce associated toxicities.
Deep dives
Renatumab Efficacy in Multiple Myeloma
Renatumab, a bispecific antibody targeting BCMA, shows promising results in Relapsed Refractory Multiple Myeloma. The Magnetism MM3 trial presented updated data, indicating an overall response rate of 60-65% and significant rates of complete response (CR) and very good partial response (VGPR). The median progression-free survival (PFS) reached around 17.5 months, with a median overall survival of 2 years. Results from both trial and compassionate use programs support Renatumab as a valuable salvage treatment, reinforcing its role in treating relapse refractory patients.
Dosing Strategy for Teclistumab
A retrospective analysis by Rahul Banerjee explores a step-up dosing approach for Teclistumab in real-world settings to manage associated toxicities. The study suggests deviations from the standard weekly dosing regimen, potentially enhancing patient experience and reducing side effects. Findings indicate a shift towards less frequent dosing schedules, such as days one, three, and five, emphasizing the importance of adapting treatments to individual patient needs and responses.
Comparison of Bispecific Antibodies
Sandhu Jagana discusses an indirect comparison between Linvosultamab and Teclistumab, showcasing improved outcomes with Linvosultamab in triple-class exposed and refractory myeloma patients. The study aligns important prognostic factors to demonstrate enhanced overall response rates, complete response rates, and progression-free survival with Linvosultamab. Notably, the safety profile of bispecific antibodies, including Linvosultamab, proves favorable compared to CAR T cell therapy, suggesting potential sequencing strategies and advancements in multiple myeloma treatment.
BCMA-targeting bispecific antibodies treat multiple myeloma by binding to BCMA on malignant plasma cells and directing T-cells to initiate targeted cell killing. This podcast provides updates on the use of BCMA-targeting bispecific antibodies in relapsed/refractory (R/R) multiple myeloma from the 2024 American Society of Clinical Oncology (ASCO) Meeting and the 29th Congress of the European Hematology Association (EHA).
You will hear from Mohamad Mohty, MD, PhD, Saint-Antoine Hospital, Paris, France, who discusses updated data from the MagnetisMM-3 trial (NCT04649359) of elranatamab and real-world findings from a French compassionate use program using this agent. Rahul Banerjee, MD, FACP, Fred Hutchinson Cancer Center, Seattle, WA, provides insights into the real-world step-up dosing of teclistamab to mitigate toxicities. Finally, Sundar Jagannath, MD, Tisch Cancer Institute at Mount Sinai, New York, NY, discusses a matched adjusted indirect comparison (MAIC) of the novel bispecific linvoseltamab with teclistamab, and the sequencing of bispecific antibodies with CAR T-cells.
