简要总结
This is a single arm, open-label, single center study to evaluate the safety and efficacy of BCMA/CD19 CAR-T cells in patients with BCMA+，CD19+ relapsed or refractory multiple myeloma.
详细描述
CD19 has been extensively evaluated as a therapeutic target for relapsed or refractory multiple myeloma by chimeric antigen receptor T cell therapy,this is a single arm, open-label, single center study to preliminary explore the safety, tolerability and cellular pharmacokinetics of Anti-BCMA and Anti-CD19 CAR-T cells in the treatment of relapsed or refractory multiple myeloma.
