Platinum Resistant Recurrent Ovarian Cancer

This is a prospective, single-center, single-arm exploratory clinical study designed to evaluate the efficacy and safety of liposomal irinotecan combined with enlonstobart in patients with platinum-resistant recurrent ovarian cancer. Eligible female participants with histologically or cytologically confirmed epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer, FIGO stage II-IV, will receive liposomal irinotecan and enlonstobart every 2 weeks. Tumor assessment will be performed every 8 weeks. Participants may discontinue study treatment in the event of disease progression, intolerable toxicity, withdrawal of consent, or other reasons judged by the investigator.

To evaluate the efficacy and safety of B013 in patients with platinum-resistant recurrent ovarian cancer.

An open, multicenter, dose-exploring Phase I trial include Part A and Part B to evaluate the safety, tolerability and efficacy of APG-2449.
