What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 27 participants in total. It began in 2022-04-22 with a primary completion date of 2029-03-31.

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.
