Clinical Study of CD7 CAR-T Cell Injection in the Treatment of Patients With Relapsed or Refractory CD7-positive Peripheral T Cell Lymphoma

Patients with recurrent/refractory PTCL were included using a single arm, open label, and single center approach. Pre treatment plan: Cyclophosphamide (CTX): 500mg/m2 × 3 days Fludarabine: 30mg/m2 × 3 days Note: Researchers can adjust the pre-treatment plan appropriately based on the patient's condition, such as CTX 300mg × Wait for 3 days. CTX and Flu were infused on the 5th to 3rd day (D-5 to D-3) before administration. RD13-02 can only be injected after 48 hours of pre-treatment.
