MM CAR-T to Upgrade Response BMT CTN 1902
a study on Multiple Myeloma
This study is designed as a Phase II, multicenter, single arm trial to assess anti-B Cell Maturation Antigen (BCMA) chimeric antigen receptor (CAR) T-cells (bb2121) to improve post autologous hematopoietic cell transplant (HCT) responses among patients with multiple myeloma (MM).
Phase II Multicenter Trial of Anti-BCMA CAR T-Cell Therapy for MM Patients With Sub-Optimal Response After Auto HCT and Maintenance Len. BMT CTN 1902
After meeting the eligibility criteria and enrolling on the trial, patients will undergo leukapheresis for collection of autologous lymphocytes, which will be sent to BMS/Celgene manufacturing facilities. Once cells have been manufactured, patients will then proceed to lymphodepleting chemotherapy with cyclophosphamide 300mg/m2 and fludarabine 30mg/m2 for 3 consecutive days followed by the infusion of BCMA CAR T-cells at a target dose of 450 x106 cells. Maintenance lenalidomide, starting at 10mg a day for 21 days of a 28-day cycle will be initiated at a minimum of at least 30 days, but no later than 180 days after the CAR T-cell infusion and will continue until the patient reaches 12 months post CAR T-cell infusion and continue free of progression
