Brief Title: Safety and Efficacy of Dual Specificity CD19 and CD22 CAR-T Cell Immunotherapy in R/R Acute B Lymphoblastic Leukemia
Official Title: A Phase I Clinical Study of Dual Specificity CD19 and CD22 Chimeric Antigen Receptor T Cell Therapy in Relapsed or Refractory Acute B Lymphoblastic Leukemia
Study ID: NCT04094766
Brief Summary: This is a single arm, open-label, dose escalation clinical study to evaluate the safety and efficacy of infusion of dual specificity CD19 and CD22 CAR-T cells in patients with relapsed and refractory acute B lymphoblastic leukemia.
Detailed Description: 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.
