CAR-T cell therapy has shown promising results for the treatment of relapsed or refractory Multiple Myeloma,however, a subset of patients relapse due to the loss of target in tumor cells.Dual Specificity CD38 and BCMA CAR-T cells can recognize and kill the malignant cells through recognition of CD38 or BCMA. This is a phase 1/2 study designed to determine the safety of dual specificity CD38 and BCMA CAR-T cells and the feasibility of making enough to treat patients with relapsed or refractory Multiple Myeloma.


    1. To evaluate the feasibility and safety of dual specificity CD38 and BCMA CAR-T cells in patients with relapsed or refractory Multiple Myeloma.
    2. To evaluate the duration of in vivo persistence of adoptively transferred T cells, and the phenotype of persisting T cells.Real Time polymerase chain receptor (RT-PCR) and Flow cytometry(FCM) analysis of PB,BM and lymph node will be used to detect and quantify survival of universal dual specificity CD38 and BCMA CAR-T cells over time.

1.For patients with detectable disease, measure anti-tumor response due to dual specificity CD38 and BCMA CAR-T cell infusions.

2.The CAR-T cells will be administered by i.v. injection over 20-30 minutes as a using Day 0: 1-5x10e6/kg total dose on day 0.
