Open-Label, Multicenter, Single Ascending Dose Study to Assess the Safety of P-BCMA-101 in Subjects With Relapsed and/or Refractory Multiple Myeloma (MM)

This is a Phase 1, open-label, multi-center study of P-BCMA-101 autologous T stem cell memory (Tscm) CAR-T cells in patients with relapsed and/or refractory MM. Rimiducid may be administered as indicated.

The study will follow a 3 + 3 design of dose-escalating cohorts. After a patient enrolls, leukapheresis will be performed to obtain peripheral blood mononuclear cells which will be sent to a manufacturing site to produce P-BCMA-101 CAR-T cells. The cells will then be returned to the investigational site and, after a standard chemotherapy based conditioning regimen, will be administered to the patient. Treated patients will undergo serial measurements of safety, tolerability and response. Rimiducid may be administered as indicated.
