Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of CAR T cell treatment targeting CD7 in patients with relapsed or refractory CD7 positive T-cell hematological maliganacies


Description:

This study is single-armed,open lable,dose escalation clinical trial.The main purpose is to evaluate the safety and efficacy of anti-CD7 CAR-T cells in relapsed/refractory patients with CD7 positive T cell malignancies,including T lymphoblastic lymphoma/leukemia ,T-cell non-Hodgkin lymphoma(peripheral T cell lymphoma,NOS,angioimmunoblastic T cell lymphoma and anaplastic large cell lymphoma).There will be three CAR T cell dose groups:0.5*10^6 cells per kilogram of body weight;1*10^6 cells per kilogram of body weight,2 *10^6 ells per kilogram of body weight.
