简要总结
Early exploratory clinical study of the safety, tolerability and initial efficacy of JY231 injection in the treatment of refractory autoimmune diseases
详细描述
This is a single-center, single-arm. open-treatment clinical study, in this study. approximately 10-20 adult and elderly patients with refractory autoimmune diseases will be enrolled for JY231 infusion therapy. The safety of JY231 was evaluated by observing adverse events after cell therapy. Evaluate the effectiveness of JY231 treatment compared to the results of the subjects' own previous standard treatment regimens or base data.
