Exploratory Clinical Study on the Safety and Efficacy of CAR19-BCMA Dual-target CAR-T in the Treatment of Relapsed / Refractory Multiple Myeloma

1. Objective to evaluate the safety and tolerability of CAR19-BCMA dual-target CAR-T in the treatment of relapsed / refractory multiple myeloma. 2. To determine the maximum tolerated dose (MTD) of car19-bcma dual target car-t in the treatment of relapsed / refractory multiple myeloma.

Inclusion: Subjects must satisfy all the following criteria to be enrolled in the study:; With Subjects' consent and signed informed consent, Subjects are willing and able to follow the planned visit, study treatment, laboratory examination and other test procedures; 2. Patients with relapsed / refractory multiple myeloma according to clinical diagnosis:; The expression of BCMA and / or CD19 in myeloma cells was positive confimed by flow cytometry or immunohistochemistry; Patients with relapsed / refractory multiple myeloma who have received at least 1 line treatment (including proteasome inhibitors (PI), immunomodulatory drugs (IMID), CD38 mAb) or are resistant to proteasome inhibitors and / or immunomodulatory agents and / or CD38 mAb in the past; Age 18-70 years old, both male and female; 4.

Human immunodeficiency virus (HIV) infection or known acquired immune deficiency syndrome (AIDS), or syphilis infection; 8. Have a history of severe allergy to biological products (including antibiotics); 9. One month after immunosuppressant withdrawal, patients with acute graft-versus-host response (GVHD) after allogeneic hematopoietic stem cell transplantation still exist; 10. There are other serious physical or mental diseases or abnormal laboratory tests that may increase the risk of participating in the study, or interfere with the results of the study, as well as patients who the investigator believes are not suitable for participating in this study; 11.
