CD19-CAR-T Cells in Patients With R/R B-ALL

Phase I Study of the Safety and Efficacy of CD19-CAR-T Cells in Patients With Relapsed or Refractory Acute B-cell Lymphoblastic Leukemia (R/R B-ALL)

This is a single center, single arm, open-lable phase 1 study to determine the safety and efficacy of autologous or donor-derived allogeneic T cells expressing CD19 chimeric antigen receptors (referred to as "CD19-CAR-T cells") in patients with relapsed or refractory acute B-cell lymphoblastic leukemia (R/R B-ALL).

Study Overview

• Status: Unknown
• Conditions: B-cell Acute Lymphoblastic Leukemia
• Intervention / Treatment: Biological: CD19-CAR-T Cells

Detailed Description

Primary objective:

To investigate the safety and efficacy of autologous or HLA-haploidentical Allo-CD19-CAR-T cells in the treatment of patients with relapsed or refractory acute B-cell lymphoblastic leukemia.

Secondary objective:

To Assess the patient's quality of life after receiving the treatment.
