CD19-directed CAR-T cell therapy has shown promising results for the treatment of relapsed or refractory acute B lymphoblastic leukemia. CD19 and CD22 are proteins usually expressed on the surface of the B leukemia cells. The dual specificity CAR enables the T-cells to recognize and kill the tumor cell through recognition of CD19 and CD22.
