Brief Summary:
The aim of this study was to evaluate the safety and efficacy of universal CD7 CART (uCD7 CART) cells in the treatment of patients with relapsed/refractory CD7-positive hematologic malignancies. In this single-arm, open-label, single-center, Phase 1 clinical trial, two cohorts were set up: (1) relapsed and refractory acute myeloid leukemia (AML) cohort; and (2) relapsed and refractory T lymphoblastic leukemia/lymphoma (T-ALL/LBL) cohort. Each cohort was planned to enroll 4-12 patients. uCD7 CART cells will be administered intravenously to explore the maximum tolerated dose (MTD) of each cohort using a 3+3 dose escalation and rapid titration design.
Detailed Description:
This study will use universal CD7 CAR-T cells to treat CD7-positive relapsed or refractory hematological malignancies, especially AML and T-ALL/LBL patients. Two cohorts were established: (1) relapsed and refractory AML cohort; and (2) relapsed and refractory T-ALL/LBL cohort. A 3+3 dose escalation and rapid titration design was used to explore the MTD for each cohort. 3+3 dose escalation CAR-T dose groups were (1) 0.5×10\^6 CART cells/kg; (2)1×10\^6 CART cells/kg;(3) 3×10\^6 CART cells/kg. A minimum of 4 and a maximum of 12 patients are expected to be enrolled. Fludarabine and cyclophosphamide-based preconditioning should be performed within 1 week prior to uCD7 CART infusion. uCD7 CART can be infused at D-1 if the requirement of 24 hours after completion of preconditioning is met. To evaluate the safety and efficacy of uCD7 CART cells in the treatment of patients with relapsed/refractory CD7-positive hematologic malignancies.
