Most patients with multiple myeloma (MM) die due to relapse resistant to current treatment, including treatment with anti-B cell maturation antigen (BCMA) CAR-T cells. To overcome some of the potential limitations of this therapy, a new and optimized Anti-BCMA CAR-T has been developed, with the aim of using it in patients with MM who relapse after Allogeneic Haematopoietic Haematopoietic Progenitor. This trial is a prospective phase I/II trial with a 3+3 design. Once Dose Limiting Toxicity is identified, Phase II will begin to assess the efficacy of the procedure.
This trial is a prospective phase I/II trial with a 3+3 design. Once Dose Limiting Toxicity is identified (up to a maximum dose of 6x106 CAR-T/kg divided over 2 days), phase II of the trial will begin to assess the efficacy of the procedure.
A number of 25 patients will be included to evaluate.
