This is a multi-center, open-label, non-randomized, single-arm clinical trial. Refractory/relapse T-NHL patients are treated with autologous and allogeneic CD7 CAR T-cell therapy. The primary objective is to prospectively evaluate the safety of CD7 CAR T cell bridging to HSCT in the treatment of r/r T-NHL. The primary endpoint is the type and incidence of dose limiting toxicity (DLT) within 21 days after CD7 CAR-T cell infusion. A total of 36 subjects is estimated to be enrolled.
