简要总结
This is an investigator-initiated trial to evaluate the safety and efficacy of anti- CD19-CAR-T cells in the relapse or refractory autoimmune diseases.
详细描述
This is an investigator-initiated trial to evaluate the safety and efficacy of anti- CD19-CAR-T cells in the relapse or refractory autoimmune diseases.
Study intervention consists of a single infusion of CAR-transduced autologous T cells administered intravenously after a lymphodepleting therapy regimen consisting of fludarabine and cyclophosphamide.
Interim analysis will be performed when the last participant finishes the visit of 12 weeks after CAR-T cells infusion.
