Clinical Trial Summary

This is an open label, single-arm, multicenter, Phase 2 study to evaluate the efficacy and safety of bb2121 in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture bb2121 chimeric antigen receptor (CAR) modified T cells. Prior to bb2121 infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide.

Description:

Anti-myeloma bridging treatment is allowed for disease control while bb2121 is being manufactured.
