Maintainance therapy period mainly includes: 1. Injection of Camrelizumab at a dose of 200mg administered intravenously every 3 weeks as one treatment cycle until disease progression, intolerable toxicity, death, or up to a maximum of 2 years. 2. Oral administration of Fluzoparib capsules at a dose of 150mg, once in the morning and once in the evening until disease progression, intolerable toxicity, death, or up to a maximum of 2 years.

ACTIVE COMPARATOR

Treatment period mainly include: 1. Injection of Paclitaxel (Albumin-bound) at a dose of 260mg/m\^2 administered intravenously every 3 weeks as one treatment cycle, for a total of 6 cycles. 2. Injection of Carboplatin (AUC=5) administered intravenously every 3 weeks as one treatment cycle, for a total of 6 cycles. 3. Injection of Camrelizumab at a dose of 200mg administered intravenously every 3 weeks as one treatment cycle, for a total of 6 cycles. 4. Radiation therapy: Not mandatory. Whether to combine radiation therapy is determined by the principal investigator based on the patient's condition. Radiation therapy includes external beam radiation and brachytherapy. Maintainance therapy period mainly includes: a) Injection of Camrelizumab at a dose of 200mg administered intravenously every 3 weeks as one treatment cycle until disease progression, intolerable toxicity, death, or up to a maximum of 2 years.
