NCT04795882

Brief Summary

This is a Phase 1 rolling 6 trial design evaluating safety of a novel BCMA Chimeric Antigen Receptor (CAR) alone and of CAR T cells engineered to co-express BCMA CAR and a CD19 CAR in patients with relapsed / refractory Multiple Myeloma. The study will assess the feasibility of generating these Advanced Therapy Investigational Products (ATIMPs) and the safety of administering the CAR T cells (either BCMA alone or co-expressed with CD19) in patients with relapsed / refractory multiple myeloma.
