  12. Received live vaccine treatment within 30 days prior to Visit 2
  13. Transplantation: History of vital organ transplantation (eg, heart, lung, kidney, liver) or hematopoietic stem cell/or bone marrow transplantation
  14. HIV positive.
  15. Active hepatitis B or C.
  16. Suffering from malignant tumors of other organs at the same time.
  17. Pregnant or lactating women.
  18. Inability to understand or follow the research protocol.
  19. Participate in other clinical investigators during the same period.
  20. Have any other clinically significant disease history or current disease that, in the judgment of the research physician, may pose a risk to the safety of the subjects, or interfere with the completion of the research procedure and the evaluation of safety and efficacy.

5. Study Description

Brief Summary
This is a phase I, interventional, single arm, open label, treatment study to evaluate the safety and tolerability of BCMA-CD19 cCAR T cells in patients with relapsed and/or refractory SLE.
Detailed Description
Systemic lupus erythematous (SLE) is a chronic diffuse connective tissue disease with unexplained etiology that can involve multiple systems in the body. SLE is considered as an incurable disease and traditional SLE treatment aims at long-term remission. Glucocorticoids combined with immunosuppressive agents are still the main treatment strategies. Recently, biological agents targeting abnormal immune cells, such as rituximab and belimumab, which deplete B cells have also achieved some success in the treatment of SLE. However, these agents cannot permanently reverse the production of abnormal antibodies as they are unable to eliminate pathogenic long-lived plasma cells. The BCMA-CD19 CAR T-cells are designed to deplete antibody-producing 'root", B cells and plasma cells.
