T-cell Acute Lymphoblastic Leukemia/Lymphoma Clinical Trial
Official title:
Cell Therapy for CD7 Positive T-cell Acute Lymphoblastic Leukemia and Lymphoblastic Lymphoma Using CD7-Specific CAR-T Cells
This is an open, single-arm, clinical study to evaluate efficacy and safety of anti CD7 CAR-T cell in the treatment of relapsed or refractory T-cell acute lymphoblastic leukemia (T-ALL) and lymphoblastic lymphoma (TLBL).
The CARs consist of an anti-CD7 single-chain variable fragment（scFv）, a portion of the human CD137（4-1BB） molecule, and the intracellular component of the human CD3ζ molecule. Prior to CAR-T cell infusion, the patients will be subjected to preconditioning treatment. After CAR-T cell infusion, the patients will be evaluated for adverse reactions and efficacy. The Main research objectives: To evaluate the safety and efficacy of CD7 CAR-T cells in patients with relapsed or refractory T-ALL/LBL The Secondary research objectives: To investigate the cytokinetic characteristics of CD7 CAR-T cells in patients with relapsed or refractory T-ALL/LBL ;
