Fluzoparib+Bevacizumab/Dietary Intervention vs Fluzoparib Monotherapy as First-line Maintenance in HRD+/- Advanced Ovarian Cancer
An Open-label, Randomized Controlled, Multicenter Study With Dual HRD-positive/Negative Cohorts Evaluating Fluzoparib Monotherapy Versus Combination Therapy With Bevacizumab or Dietary Intervention as Maintenance Treatment Following First-line Platinum-based Chemotherapy in Advanced Ovarian Cancer

Conditions
Summary
Fluzoparib has been approved for the first-line maintenance treatment of advanced ovarian cancer in the full population . Previous studies have demonstrated that anti-angiogenic agents enhance tumor cell sensitivity to PARP inhibitors . In vitro evidence suggests that low-carbohydrate culture conditions may restore PARP inhibitor sensitivity in HRD-negative tumor cells. This study aims to validate the survival benefits of fluzoparib combined with bevacizumab in HRD-positive ovarian cancer patients during first-line maintenance therapy and explore the efficacy of fluzoparib combined with a dietary intervention in HRD-negative populations.

- Patients with stable CNS metastases (confirmed by imaging for ≥1 month) after prior systemic/local therapy (e.g., surgery/radiotherapy) and off steroids (>10 mg/day prednisone equivalent) for >2 weeks may be eligible.
- Prior use of PARP inhibitors (e.g., olaparib, niraparib, rucaparib, pamiparib, fluzoparib).
- .Inability to swallow tablets or gastrointestinal dysfunction affecting drug absorption (per investigator judgment).
- Bowel obstruction or gastrointestinal perforation within 3 months prior to randomization.
- Symptomatic malignant ascites/pleural effusion requiring drainage or drainage within 3 months prior to randomization.
- Poorly controlled cardiac disease :
- NYHA Class ≥II heart failure.
- Unstable angina.
