Researchers are evaluating a medicine called elranatamab for the treatment of multiple myeloma (MM), a type of cancer. This study focuses on people aged 18 or older who have MM that has returned or not responded to previous treatments, including prior use of an anti-CD38 antibody and lenalidomide. The goal is to compare elranatamab to other common combination therapies that include 2 to 3 different MM medicines. This is a Phase 3 study to learn about the safety and effectiveness of elranatamab compared to these other treatments. Participants will be randomly assigned to receive either elranatamab or a combination therapy selected by the study doctor. Elranatamab is given as a shot under the skin at the study clinic about once a week, which may later reduce in frequency. The combination therapy options include medicines taken by mouth and given either as shots under the skin or through a needle in the vein at the clinic. The combination medicines used may be elotuzumab, pomalidomide, dexamethasone, bortezomib, or carfilzomib, depending on the chosen treatment plan. Participants may continue their assigned treatment until their MM stops responding. During the study, participants will visit the clinic regularly for monitoring and evaluation. Researchers will track how well the treatments work by measuring progression-free survival and will watch for any side effects or safety concerns. Follow-up will continue after treatment ends through phone calls or visits. The study may last up to about 5 years to fully assess the outcomes of the treatments.
