CD19/CD22 Bispecific CAR-T Cell Therapy for Relapsed/Refractory B-cell Lymphoma or Acute Lymphoblastic Leukemia: a Prospective, Single-arm, Single-center, Phase 2 Clinical Trial

Study Summary

CAR-T cell therapy targeting CD19 has been shown to be effective in heavily-pretreated B-cell ALL or NHL, but relapses post-CAR-T are common, and CD19 antigen loss is one of the reasons. Thus, we supposed that CD19/CD22 bispecific CAR-T cell therapy would be more effective and less relapses would occur in B-ALL or NHL. In this prospective phase 2 clinical trial, we aim to explore the efficacy and safety of CD19/CD22 bispecific CAR-T cell therapy in relapsed/refractory B-ALL or Large B cell lymphoma.
