Solid Tumor
Conditions
Brief summary
This is a phase I, open-label, single-arm study conducted to evaluate the efficacy, safety and PK of CGC729 in the treatment of advanced malignant solid tumors. Condition or disease:advanced malignant solid tumors. Intervention/treatment:Biological: CD70 CAR-NKT cells. Phase:I
Detailed description
This was a dose-expansion study, we plan to enroll 6 to 12 patients with CD70-positive advanced malignant solid tumors to CGC729 treatment. The intended enrollment for the evaluation of treatment efficacy and safety was planned to be 3 to 6 patients per tumor type. We used leukapheresis for cell collection. The lymphodepletion procedure was conducted using a combination of fludarabine and cyclophosphamide.
