研究概览

简要总结

This is a single arm study to evaluate the efficacy and safety of CD19 and CD22 targeted CAR-T cells therapy for patients with relapsed/refractory B Cell Leukemia and Lymphoma.

详细描述

Although the CD19 targeted CAR-T cell therapies have gained significant results in patients with relapsed and refractory B-cell Leukemia and Lymphoma. There are patients who resisted anti-CD19 CAR-T cells or with CD19 negative relapse. To make further improvement, We launch such a clinical trial using CD19 and CD22 targeted CAR-T cells for patients with relapsed and refractory B Cell Leukemia and Lymphoma to evaluate the efficacy and safety of CD19 and CD22 targeted CAR-T cell therapy.
