This is a single-center, single-arm clinical study to evaluate the efficacy and safety of iparomlimab and tovorilimab (QL1706) combined with paclitaxel, carboplatin, and bevacizumab as neoadjuvant therapy for advanced ovarian cancer.

Non-epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer (e.g., germ cell tumors), as well as ovarian tumors of low malignant potential (e.g., borderline ovarian tumors).
Prior immunotherapy, including immune checkpoint inhibitory antibodies (e.g., anti-PD-1, anti-PD-L1, anti-CTLA-4 antibodies, etc.), immune checkpoint agonistic antibodies (e.g., anti-ICOS, anti-CD40, anti-CD137, anti-GITR, anti-OX40 antibodies, etc.), and immune cell therapy.
Known hypersensitivity to large molecule protein preparations. Contraindications or allergy to any component of iparomlimab and tovorilimab (QL1706), paclitaxel, or carboplatin.
