Fluzoparib Combined With Bevacizumab in PSROC Previously Treated With PARPi

Phase 2

Recruiting

• Conditions: Ovarian Cancer
• Interventions: Drug: fluzopanib and bevacizumab

• Registration Number: NCT05551208
• Lead Sponsor: Chongqing University Cancer Hospital

Brief Summary

There are more and more PARPi(PARP inhibitors) resistance for ovarian cancer patients after previous use of PARP inhibitors. Basic studies have found that there is synergistic effect of bevacizumab combined with PARPi. Therefore we designed the study to include 42 ovarian cancer patients who had PARPi for at least half a year and then relapsed (platinum-sensitive, previously 1-3 lines of chemotherapy). After getting complete remission or partial remission with chemotherapy containing platinum and bevacizumab, fluzopanib and bevacizumab were used for maintenance treatment. The progression-free survival, ORR, DCR, DoR, and safety were evaluated based on RECIST V1.1.

Detailed Description

Genetic testing of tissue samples before and after the maintenance therapy were also used to further explore the pattern of gene mutations and the subgroups who may benefit.
