简要总结
A Phase I, Multicenter study to evaluate the safety, tolerability, and Efficacy of LCAR-T2C CAR-T cells in relapsed or refractory CD4+T Lymphocyte Tumor Patients.
详细描述
This is an open, dose escalation/dose extension study of LCAR-T2C CAR-T cells administrered to patients with T lymphocyte tumor. The aim of the study is to evaluate the safety, tolerability, and efficacy of LCAR-T2C CAR-T cells. The auto-CAR-T cells will be infused in single-dose.
