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.

  7. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
  8. Subjects must have measurable disease, including at least one of the criteria below:
  9. Serum M-protein greater or equal to 1.0 g/dL
  10. Urine M-protein greater or equal to 200 mg/24 h
  11. Serum free light chain (FLC) assay: involved FLC level greater or equal to 10 mg/dL (100 mg/L) provided serum FLC ratio is abnormal
