Immune nephritis is a chronic glomerular disease originating in the kidney caused by various etiologies.Clinically, secondary chronic kidney damage caused by systemic diseases such as diabetes, systemic lupus erythematosus and gout is named after its primary disease, such as diabetic nephropathy and lupus nephritis. Autoimmune diseases only show local pathological damage, but more often systemic lesions. If not diagnosed and treated in time or poorly controlled, a risk of disability or even death as the course of the disease progresses. Studies have shown that B cells can present their own antigens to autoimmune T cells to promote the release of inflammatory factors, or they can differentiate into plasma cells to release autoantibodies, and play an important role in the occurrence and progression of autoimmune diseases. In recent years, it has become a major research focus to deplete B cells in patients or inhibit B cell function. This research focuses on CAR-T cells killing B cells.
Based on the current research progress, our center intends to conduct research on the safety and effectiveness of CD19/BCMA CAR-T cells in the treatment of refractory systemic lupus erythematosus.

Experimental: Treatment of Immune Nephritis
Administration of CD19/BCMA CAR T-cells A dose levels of 1-4*10E6/kg are administrated for each subject.
Biological: Assigned Interventions CD19/BCMA CAR T-cells
Drug: CD19/BCMA CAR T-cells Each subject receive CD19/BCMA CAR T-cells by intravenous infusion Other Name: CD19/BCMA CAR T-cells injection
- Dose-limiting toxicity (DLT) [ Time Frame: Baseline up to 28 days after CD19/BCMA CAR T-cells infusion ]Adverse events assessed according to NCI-CTCAE v5.0 criteria
- Incidence of treatment-emergent adverse events (TEAEs) [ Time Frame: Up to 90 days after CD19/BCMA CAR T-cells infusion ]Incidence of treatment-emergent adverse events [Safety and Tolerability]
- Concentration of CAR-T cells [ Time Frame: From admission to the end of the follow-up, up to 2 years ]In peripheral blood and bone marrow
- Objective Response Rate, ORR [ Time Frame: In 3 months of CD19/BCMA CAR-T cell infusion ]Proportion of subjects with complete or partial remission
- Disease control rate, DCR [ Time Frame: From Day 28 CD19/BCMA CAR-T infusion up to 2 years ]The percentage of patients with remission and stable disease after treatment in the total evaluable cases.
- Duration of remission, DOR [ Time Frame: 24 months post CD19/BCMA CAR-T cells infusion ]The time from the first assessment of remission or partial remission of the disease to the first assessment of disease progression or death from any cause
- Progression-free survival, PFS [ Time Frame: 24 months post CD19/BCMA CAR-Tcells infusion ]The time from cell reinfusion to the first assessment of disease progression or death from any cause
- Overall survival, OS [ Time Frame: From CD19/BCMA CAR-T infusion to death，up to 2 years ]The time from the cell reinfusion to death due to any cause
