Dual Target CAR-T Cells in B-cell Acute Lymphoblastic Leukemia
Sponsor:

Shenzhen University General Hospital

Information provided by (Responsible Party):

July

Brief Summary:

Prospectively evaluate the safety and effectiveness of CD19/CD22 dual-target CAR-T cells in the treatment of relapsed/refractory B-cell acute lymphoblastic leukemia.

Condition or disease

Dual-target CAR-T Cells

B ALL

Relapse

Refractory B Acute Lymphoblastic Leukemia

Intervention/treatment

Dual target CAR-T cell therapy

Phase

PHASE1

PHASE2

Detailed Description:

Prospectively evaluate the safety and effectiveness of CD19/CD22 dual-target CAR-T cells in the treatment of relapsed/refractory B-cell acute lymphoblastic leukemia. Strictly follow the inclusion criteria to screen eligible subjects for inclusion in clinical trials. The selected patients received CD19/CD22 dual-target CAR-T cell therapy. After the treatment is over, follow-up regularly to determine the survival status and follow-up treatment.
