A Phase 3 Study Comparing Linvoseltamab to Elotuzumab, Pomalidomide, and Dexamethasone for Adults With Relapsed or Refractory Multiple Myeloma

What this Trial Is About

Researchers are evaluating linvoseltamab, an experimental drug also called REGN5458, in adults with multiple myeloma that has returned or needs treatment again after one to four prior therapies. The study compares linvoseltamab to a combination of three cancer drugs elotuzumab, pomalidomide, and dexamethasone EPd. This phase 3 study aims to assess the safety and effectiveness of linvoseltamab versus EPd in participants who have standard treatment options available and have previously received certain therapies including lenalidomide and a proteasome inhibitor. Participants are randomly assigned to one of two groups one receiving linvoseltamab by intravenous infusion, and the other receiving the EPd combination, with elotuzumab given by infusion and pomalidomide and dexamethasone given by mouth or infusion. The study focuses on how long participants benefit from the treatments, the degree of tumor response, side effects, survival, and pain improvement. During the study, participants will undergo regular assessments including disease response evaluations based on established criteria, safety monitoring, and patient-reported outcomes like pain and quality of life questionnaires. The primary measure is progression-free survival over up to about five years. Researchers will also track overall survival, adverse events, antibody responses, and other health status measures. Participation involves treatment, follow-up visits, and ongoing monitoring to understand the treatments impact.
