재발성 또는 불응성 다발성골수종 성인에서 주사 에텐타미그와 경구 포말리도마이드 대 표준 치료의 부작용 및 질병 활성도 변화 평가 연구

Multiple myeloma (MM) is a plasma cell malignancy characterized by the proliferation of clonal plasma cells in the bone marrow. The disease primarily localizes to the bones and bone marrow, with resultant cytopenias, bone pain, fractures, infections, hypercalcemia, and renal failure. This study aims to evaluate the safety and change in disease activity of etentamig in combination with pomalidomide compared with standard available therapies in participants with relapsed or refractory multiple myeloma who have received 1-3 prior lines of treatment, including lenalidomide. Etentamig is an investigational drug being developed for the treatment of relapsed or refractory multiple myeloma. This is a randomized, open-label study. The study will include a safety run-in portion and a randomized portion. The safety run-in participants will receive etentamig in combination with pomalidomide. The randomized portion of the study participants will receive either etentamig with pomalidomide or Standard Available Therapies (SATs). Approximately 520 participants will be enrolled in the study at approximately 200 sites worldwide. Prior to initiation of the randomized portion of the study, the safety run-in will be conducted in which participants will receive etentamig injections plus oral pomalidomide. Following review of the safety run-in data and per protocol-defined criteria, the study will advance to the randomized portion where participants will be randomized to receive either etentamig injections plus oral pomalidomide or investigator's choice of SAT: SC daratumumab, oral pomalidomide, and oral/ IV dexamethasone (DPd); SC daratumumab, IV carfilzomib, and oral/IV dexamethasone (DKd); or SC teclistamab monotherapy. The total study duration is approximately 75 months There may be higher treatment burden for participants in this trial compared to their standard of care due to study procedures. Participants will attend regular visits during the study at a hospital or clinic. The effects of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
