description
Cohort A will enroll participants with multiple myeloma who have previously received greater than or equal to (\>=) 3 prior lines of therapy and have not been exposed to T cell redirection therapies. Participants will receive talquetamab subcutaneously (SC) at a recommended Phase 2 dose (RP2D) selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study. All participants (ongoing and those who are in follow-up) will transition to open-label extension (OLE) phase and will continue to receive the study treatment. Upon approval of amendment 19 and notification from the sponsor, participants will transition to the long-term extension (LTE) and will continue to receive study treatment.
