Evaluation of Sup19 CAR-T cells in cases where previous CD19-targeted therapy has failed or where CD19 Evaluation of Safety and Efficacy in the Treatment of Low-Grade Hematological Malignancies: A Prospective, Single-Arm Clinical Study Research

The objective of this study was to evaluate the safety and efficacy of CD180 CART cells in the treatment of patients with relapsed/refractory CD180-positive hematological malignancies. In this single-arm, open-label, single-center, Phase I clinical trial, two cohorts were set up: (1) relapsed and refractory AML cohort; and (2) relapsed and refractory B-ALL/LBL cohort. CD180 CART cells will be administered intravenously using a 3+3 dose escalation and rapid titration design, with CART dose groups of (1) 0.5×10\^6 CART cells/kg;(2)1×10\^6 CART cells/kg; and (3) 3×10\^6 CART cells/kg. Each cohort was planned to enroll 6-12 patients.
