Multiple myeloma is a type of blood cancer that affects the bone marrow. This study is for people whose myeloma has come back or hasn't responded to previous treatments. The study compares two treatment combinations. One group gets iberdomide, daratumumab, and dexamethasone (IberDd), while the other group gets daratumumab, bortezomib, and dexamethasone (DVd). The goal is to see which combination works better and is safer for patients. Key Points:
- The study involves two stages and includes about 864 participants overall.
- Participants receive treatments until the disease worsens or side effects are too severe.
- Participants must have tried 1-2 prior treatments and show disease progression.
