The purpose of this study is to evaluate the safety of a drug called etentamig and identify the optimal dose of the drug when combined with another drug, daratumumab, in people with newly diagnosed multiple myeloma (NDMM) who are not eligible for transplant. Researchers will monitor the effect of etentamig on the patient’s cancer. Etentamig is a bispecific antibody, and daratumumab is a monoclonal antibody (proteins made in a lab that are designed to help the immune system kill cancer cells). Participants will be randomly assigned to 1 of 3 treatment dose groups of etentamig in combination with daratumumab. Once the optimal dose is found, participants will be randomly assigned to receive either etentamig with daratumumab (Etentamig + D), or standard-of-care treatment approved by the U.S. Food and Drug Administration (FDA) combining daratumumab, lenalidomide, and dexamethasone (DRd). Study procedures also include exams, electrocardiograms, blood draws, imaging, and biopsy. The use of etentamig and daratumumab in this study is investigational.
