简要总结
This is an open label, single-arm, Phase 2 study to evaluate the efficacy and safety of Anti-BCMA/GPRC5D CAR-T in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture Anti-BCMA/GPRC5D chimeric antigen receptor (CAR) modified T cells. Prior to Anti-BCMA/GPRC5D infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide.

This open label, single-arm, Phase 2 study aims to evaluate the efficacy and safety of Anti-BCMA/GPRC5D CAR-T in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture Anti-BCMA/GPRC5D chimeric antigen receptor (CAR) modified T cells. Prior to Anti-BCMA/GPRC5D infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide. After infusion, the investigators will observe the characteristics of dose limited toxicity (DLT), and determine the maximum tolerable agent MTD and rp2d were confirmed. To provide basis for the dosage and treatment plan of cell products in follow-up clinical trials.
