简要总结
This trial aims to evaluate the safety and efficacy of BCMA-UCART in treating patients with relapsed or refractory multiple myeloma.
详细描述
BCMA(B-Cell maturation antigen) is a tumor antigen of multiple myeloma. Using a genetic engineering strategy to assemble an anti-BCMA CAR(chimeric antigen receptor) in T cells will help these CART cells to recognize and kill BCMA-expressing MM tumor cells. BCMA-UCART is a kind of allogeneic CART, originating from T cells of health donors. This open-label, dose-escalation study aims to evaluate the safety and anti-tumor efficacy of BCMA-UCART in treating relapsed or refractory multiple myeloma.
