During the Multiple Myeloma Hub virtual symposium held on March 11, 2024, “Current and future perspectives for bispecific antibodies in multiple myeloma: Learnings from 2023,” Naresh Bumma, The Ohio State University, Columbus, US, delivered a presentation on B-cell maturation antigen (BCMA)-directed bispecific antibodies in multiple myeloma (MM).

Bumma provided an overview of T-cell engagement in relapsed/ refractory MM (Figure 1), sharing the latest clinical trial data on single agents and combination therapies in MM, including BCMA-directed bispecific antibodies (Figure 2). Bumma highlighted patient-specific clinical factors, preferences, and access as determinants of treatment selection, then closed with an overview of strategies to effectively manage adverse events and infections associated with the use of bispecific antibodies.
