About this trial
This study is a randomized, open-label, multi-cohort, multicenter clinical trial, aimed at evaluating the efficacy and safety of Fluzoparib monotherapy, Fluzoparib in combination with Bevacizumab, and standard chemotherapy (Paclitaxel plus Carboplatin) as neoadjuvant treatments in newly diagnosed, germline BRCA1/2-mutated epithelial ovarian cancer patients (FIGO stage III/IV). The study also aims to assess the efficacy and safety of Fluzoparib as maintenance therapy following surgery and chemotherapy.
The primary endpoint of the study is the objective response rate (ORR) for neoadjuvant therapy, as assessed by the investigator using RECIST v1.1 criteria. Secondary endpoints include R0 resection rate, overall survival (OS), and progression-free survival (PFS). The study will also evaluate the safety, tolerability, and patient-reported outcomes (EQ-5D-5L) across the three treatment cohorts.
Eligibility criteria
Qualifiers
The subject voluntarily agrees to participate and signs the informed consent form.
Age ≥18 years (calculated as of the date of signing the informed consent).
Pathologically diagnosed with newly diagnosed, FIGO stage III-IV high-grade (or moderate/low-grade) serous ovarian cancer, fallopian tube cancer, or primary peritoneal cancer; grade ≥II endometrioid adenocarcinoma of the ovary; Mixed tumors: high-grade serous or ≥II grade endometrioid component must be >50%.
The subject has at least one measurable lesion that can be assessed by CT or MRI (RECIST v1.1).
Disqualifiers
Patients with other untreated malignant tumors within the past 5 years, except for cured skin basal cell carcinoma, cervical carcinoma in situ, and breast cancer without relapse for over 3 years after radical surgery.
Patients with untreated central nervous system metastases. Patients who have previously received systemic or curative brain or meningeal metastasis treatment (radiotherapy or surgery) and have stable imaging confirmed for at least 1 month, and have stopped systemic steroid treatment (dosage >10 mg/day prednisone or equivalent) for more than 2 weeks, and have no clinical symptoms, may be included.
Patients who have previously received treatment with known or potential PARP inhibitors or Bevacizumab.
Patients unable to swallow tablets or with gastrointestinal dysfunction that may affect drug absorption, as judged by the investigator.
