Fluzoparib + Bevacizumab vs Olaparib + Bevacizumab for Maintenance Therapy in HRD-Positive Advanced Ovarian Cancer

Summary

The PAOLA-1 trial demonstrated that for HRD-positive patients who received first-line chemotherapy combined with bevacizumab, sequential maintenance therapy with olaparib plus bevacizumab yielded a progression-free survival (PFS) of up to 46.8 months, with an olaparib-related treatment discontinuation rate of approximately 20%. The combination of olaparib and bevacizumab has been recommended by multiple clinical guidelines as the first-line maintenance regimen for HRD-positive patients treated with first-line chemotherapy plus bevacizumab. This regimen has obtained approved indications and been covered by national medical insurance. In clinical practice, around 30% of patients receiving chemotherapy plus bevacizumab adopt olaparib combined with bevacizumab for first-line maintenance treatment. Fluzoparib has been approved in China for first-line maintenance therapy in the overall patient population. The treatment discontinuation rate of fluzoparib plus apatinib is merely about 2%. However, there is currently no available data regarding fluzoparib combined with bevacizumab in the HRD-positive population, and the clinical value of this regimen remains to be further explored. This study aims to generate efficacy and safety data for olaparib plus bevacizumab versus fluzoparib plus bevacizumab in HRD-positive patients who have undergone first-line chemotherapy combined with bevacizumab, so as to provide objective evidence for clinical medication decisions.
