Study Overview
Brief Summary
This is a single arm, open-label, single center study to determine the safety and efficacy of Anti-CD19 CAR-T cells in patients with relapsed or refractory acute lymphoblastic leukemia and Lymphomas.
Detailed Description
CD19 has been extensively evaluated as a therapeutic target for relapsed or refractory B cell malignancy by chimeric antigen receptor T cell therapy,this is a single arm, open-label, single center study to determine the safety and efficacy of Anti-CD19 CAR-T cells in patients with refractory acute lymphoblastic leukemia and Lymphomas.
