RD13-02 Cell Injection in Patients with Relapsed or Refractory CD7-Positive Natural Killer/T Cell Malignancies

This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 Chimeric Antigen Receptor-T(CAR-T) therapy for patients with CD7-positive relapsed or refractory natural killer/T cell lymphoma, and to evaluate the pharmacokinetics of CD7 CAR-T in patients。
