Summary
Brief summary (as posted)
This is single center, open-label phase I, non-randomized study which will enroll patients with recurrent advanced ovarian cancer to evaluate the safety, feasibility, and efficacy of fully human B7H3 CAR-T cells (fhB7H3.CAR-Ts) via using a '3+3+3' dose escalation design. In the dose expansion cohort, six patients will be enrolled to further assess their efficacy with the optimal dosage.

- fhB7H3.CAR-T cells
- description
- In phase I study, 9 enrolled patients diagnosed with advanced ovarian cancer will receive one-time infusion of fhB7H3.CAR-Ts at the doses of 1×10\^6/kg, 3×10\^6/kg and 5×10\^6/kg, 3 patients for each dose. To further confirm the therapeutic efficacy, in phase II study, 6 enrolled patients will receive an optimal dose (balancing effectiveness and toxicity) of fhB7H3.CAR-Ts. Prior to receiving the infusions, patients will undergo lymphodepletion with fludarabine and cyclophosphamide.
