Targeting CD5 CAR-T Cells in the Treatment of r/r CD5+ T-lymphoma

In this study, 30 patients with relapsed refractory T-lymphoma were proposed to undergo CD5 CAR-T Cells therapy. Under the premise that its safety has been clarified in previous studies, further observation and evaluation of the effectiveness of CD5 CAR-T Cells therapy for relapsed refractory T-lymphoma; At the same time, on the basis of expanding the sample size, more safety data on CD5 CAR-T Cells treatment for relapsed refractory T-lymphoma were accumulated.
