Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients with Refractory Autoimmune Diseases will receive CD19 CAR T cells. The primary objective is to evaluate the safety and efficacy of CD19 CAR T cell therapy in subjects with Refractory Autoimmune Diseases and to determine the optimal biological dose (OBD) in phase I and to learn about the efficacy CD19 CAR T-cell therapy in patients with Refractory Autoimmune Diseases in phase II.
The primary endpoint is to evaluate the incidence and severity of cytokine release syndrome and severe neurotoxic adverse events within 28 days after CAR-T cell infusion.A total number of 3o subjects will be enrolled.
