Due to the lack of effective predictive molecular markers in the maintenance treatment phase, it is difficult to assess the effectiveness of maintenance treatment. This project plans to collect blood and urine from subjects before maintenance treatment, during relapse, and for follow-up molecular marker exploration research.
The study will be a Prospective, Single-arm, Phase Ⅱ Clinical Study. This study intends to explore the efficacy and safety of Fuzuloparib combined with bevacizumab in the maintenance treatment of patients with platinum-sensitive ovarian cancer. The progression-free survival, OS, and safety were evaluated based on RECIST V1.1.
