About this trial

This study is a single center, open label exploratory clinical trial aimed at evaluating the safety and efficacy of universal CD19 CAR-T therapy in subjects with autoimmune diseases.

The study will adopt the traditional dose escalation model "3+3" design, setting up three dose groups with a starting dose of 0.5 × 106 CAR+T cells/kg for incremental DLT observation. Safety and efficacy follow-up will be conducted for 24 months after cell infusion to observe the safety of the universal CD19 CAR-T and conduct preliminary efficacy evaluation.
