Brief summary: This is a Prospective,Single-Center, Single-Arm, Phase 2 study to evaluate the efficacy and safety of Fluzoparib Combined With QL1101, as maintenance treatment, in patients with Advanced FIGO Stage III or IV High Grade Serous or Endometrioid Ovarian, Fallopian Tube, or primary peritoneal cancer following front-line platinum-based chemotherapy with QL1101. Eligible participants who achieve complete response (CR) or partial response (PR) following treatment with platinum-based chemotherapy in addition to QL1101 will be enrolled in the study and will receive maintenance treatment with fluzoparib (for up to 2 years) combined with QL1101 (for up to 10 months during the maintenance phase or up to a total of 15 months inclusive of the approximately 5 months of bevacizumab received with chemotherapy) or until disease progression, unacceptable toxicity, participant withdrawal, Investigator's decision, or death, whichever comes first.
