Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single center, open-label ,phase 1/2 study to evaluate the safety and efficacy of targeted CD19/CD22 chimeric antigen receptor engineered T cell immunotherapy (CART) in the treatment of CD19/CD22 positive Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The patients will receive infusion of CART cells targeting CD19 and CD22 to confirm the safety and efficacy of CD19/CD22 CART Cells in Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia.
