Study Details

This phase II trial compares the effect of the combination of daratumumab-hyaluronidase (daratumumab) and teclistamab to the usual treatment of daratumumab, pomalidomide, dexamethasone or daratumumab, carfilzomib and dexamethasone in treating patients with multiple myeloma that has not responded to previous treatment (refractory) or that has come back after a period of improvement (relapsed). Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Teclistamab is a bispecific antibody that can bind to two different antigens at the same time. Teclistamab binds to B-cell maturation antigen, a protein found on some B-cells and myeloma cells, and CD3 on T-cells (a type of white blood cell) and may interfere with the ability of cancer cells to grow and spread. Pomalidomide is in a class of medications called immunomodulatory agents. It works by helping the immune system kill cancer cells and by helping the bone marrow to produce normal blood cells. Dexamethasone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Carfilzomib, a type of proteasome inhibitor, blocks the action of enzymes called proteasomes, which may help keep cancer cells from growing and may kill them. Giving daratumumab and teclistamab may be more effective than the usual treatment of daratumumab, pomalidomide, dexamethasone or daratumumab, carfilzomib and dexamethasone in reducing myeloma cells to undetectable levels in patients with relapsed or refractory multiple myeloma.

Arms

  • Active Comparator: Arm A Treatment I (DPd)
    Patients receive daratumumab-hyaluronidase SC over 3-5 minutes on days 1, 8, 15, and 22 of cycles 1 and 2, on days 1 and 15 of cycles 3-6, then on day 1 of subsequent cycles. Patients also receive pomalidomide PO on days 1-21 of each cycle, dexamethasone PO or IV on days 1, 8, 15, and 22 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo urine and blood sample collection, bone marrow biopsy, and FDG PET/CT throughout the study.
  • Active Comparator: Arm A Treatment II Option 1 (DKd)
    Patients receive daratumumab-hyaluronidase SC over 3-5 minutes carfilzomib IV on days 1, 2, 8, 9, 15, and 16 of each cycle, and dexamethasone PO or IV on days 1, 2, 8, 9, 15, and 16 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo urine and blood sample collection, bone marrow biopsy, and FDG PET/CT throughout the study.
  • Active Comparator: Arm A Treatment II Option 2 (DKd)
    Patients receive daratumumab-hyaluronidase SC over 3-5 minutes on days 1, 8, 15, and 22 of cycles 1 and 2, on days 1 and 15 of cycles 3-6 and on day 1 of subsequent cycles, carfilzomib IV on days 1, 8, and 15 of each cycle, and dexamethasone PO or IV on days 1, 8, 15, and 22 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo urine and blood sample collection, bone marrow biopsy, and FDG PET/CT throughout the study.
  • Experimental: Arm B (daratumumab, teclistamab)
    Patients receive daratumumab-hyaluronidase SC over 3-5 minutes on days 1, 8, 15, and 22 of cycles 1 and 2, on days 1 and 15 of cycles 3-6 and on day 1 of subsequent cycles. Patients also receive teclistamab SC on day 2, 4, 8, 15 and 22 of cycle 1, on days 1, 8, 15, and 22 of cycle 2, on days 1 and 15 of cycles 3-6 and then on day 1 of subsequent cycles. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo urine and blood sample collection, bone marrow biopsy, and FDG PET/CT throughout the study.
