uCD7 CART for Relapsed or Refractory CD7 Positive Hematologic Malignancies

Subjects screened to meet the requirements for uCD7 CART use will enter clinical trials. Subjects were assessed at baseline. Fludarabine (Flu) and cyclophosphamide (CTX) based preconditioning should be performed within 1 week prior to uCD7 CART infusion: Flu 30mg/m2 ×3 days; CTX 500mg/m2 ×3 days. The investigator can adjust the pretreatment regimen appropriately according to the condition of the subject, such as increasing the dose of CTX to 600mg/m2 ×3 days, increasing the application of cytarabine and etoposide. Infusion of uCD7 CART must be performed 24 hours after completion of chemotherapy preconditioning. uCD7 CART can be infused at D-1 if the requirement of 24 hours after completion of preconditioning is met.
