SupCD7 CART for Relapsed or Refractory CD7 Positive Hematologic Malignancies

Recruiting now · Phase 1/Phase 2

Conditions studied: T Lymphoblastic Leukemia/Lymphoma, Acute Myeloid Leukemia (AML)

In brief

The aim of this study was to evaluate the safety and efficacy of supCD7 CART cells in the treatment of patients with relapsed/refractory CD7-positive hematologic malignancies. In this single-arm, open-label, single-center, Phase Ⅰ+Ⅱ clinical trial, two cohorts were set up: (1) relapsed and refractory AML cohort; and (2) relapsed and refractory T-ALL/LBL cohort. Each cohort was planned to enroll 4-12 patients. SupCD7 CART cells will be administered intravenously to explore the MTD of each cohort using a 3+3 dose escalation and rapid titration design.
