Safety and Efficacy of CD19 Targeted CAR-T Therapy for Refractory Autoimmune Disease

the CD19 targeted CAR-T cell therapies have gained significant results in patients with relapsed and refractory B-cell Leukemia and Lymphoma. Otherwise, some studies have shown that the use of CD19-targeted CAR-T therapy in refractory SLE can improve the autoimmune symptoms of patients, and at the same time, immunosuppressants and hormones can be stopped to maintain long-term autoimmune indicators normal.To verify the safety and efficacy, the investigators launch such a clinical trial using CD19 targeted CAR-T cells for patients with Refractory Autoimmune Disease.
