Lymphoma, T-Cell
Conditions
Brief summary
This study is an open and prospective clinical study, taking patients with relapsed or refractory CD7+ lymphoma as the test subjects, in order to evaluate the safety and efficacy of Senl-T7 CAR-T for patients with CD7+ lymphoma.
Detailed description
Main research purposes: To evaluate the safety and efficacy of Senl-T7 CAR-T for relapsed or refractory CD7+ lymphoma Secondary research purpose: To investigate the cytokinetic characteristics of Senl-T7 CAR-T for relapsed or refractory CD7+ lymphoma.
