Brief summary
Clinical Trial for the safety and efficacy of CD19-BAFF CAR-T cells therapy for refractory/relapsed B-cell acute lymphoblastic leukemia and B-cell non-Hodgkin lymphoma.
Detailed description
In this study, 20 patients with relapsed refractory B-cell ALL and B-cell NHL were proposed to undergo CD19-BAFF CAR-T cell therapy. Under the premise that its safety has been clarified in previous studies, further observation and evaluation of the effectiveness of CD19-BAFF CAR-T cell therapy for relapsed refractory B-cell ALL and B-cell NHL; At the same time, on the basis of expanding the sample size, more safety data on CD19-BAFF CAR-T cell treatment for relapsed refractory B-cell ALL and B-cell NHL were accumulated, including rare and delayed complications.
Interventions
Each subject receive CD19-BAFF Targeted CAR T-cells by intravenous infusion
