SUCCESSOR-2: This phase III study is investigating whether adding a new targeted therapy (CC-92480) to the combination treatment of targeted therapy and steroids (carfilzomib and dexamethasone) improves the effectiveness of treating multiple myelomaA Phase 3, Two-stage, Randomized, Multicenter, Open-label Study Comparing CC-92480 (BMS-986348), Carfilzomib, and Dexamethasone (480Kd) Versus Carfilzomib and Dexamethasone (Kd) in Participants With Relapsed or Refractory Multiple Myeloma (RRMM)

Inclusion

• Participant has documented diagnosis of multiple myeloma and measurable disease, defined as any of the following:

  • Myeloma-protein (M-protein) ≥ 0.5 grams/deciliter (g/dL) by serum protein electrophoresis (sPEP), or
  • M-protein ≥ 200 milligrams (mg)/24-hour urine collection by urine protein electrophoresis (uPEP) or,
  • For participants without measurable disease in sPEP or uPEP: serum free light chain levels > 100 mg/liter (L) (10 mg/dL) involved light chain and an abnormal κ/λ free light chain ratio .
• Participant has received at least one prior line of anti-myeloma therapy. Note: One line can contain several phases (e.g., induction, [with or without] hematopoietic stem cell transplant, (with or without) consolidation, and/or [with or without] maintenance therapy).
• Participant must have received prior treatment with lenalidomide and at least 2 cycles of an anti-CD38 monoclonal antibody (mAb) (participants who were intolerant of an anti-CD38 mAb and received < 2 cycles are still eligible).
• Participant achieved minimal response or better to at least 1 prior anti-myeloma therapy.
• Participant must have documented disease progression during or after their last antimyeloma regimen.
