关键词: PARP inhibitor fluzoparib BRCA1/2 ovarian cancer

摘要:
Fluzoparib (PARP inhibitor) showed promising anti-tumor activity for advanced ovarian cancer in a phase 1 study. This study aimed to assess the efficacy and safety of fluzoparib in patients with germline BRCA1/2-mutated recurrent ovarian cancer. This open-label, multi-center, single-arm, phase 2 study enrolled patients with platinum-sensitive recurrent ovarian cancer and germline BRCA1/2 mutation who had previously received 2-4 lines of platinum-based chemotherapy. Fluzoparib 150 mg was administered orally twice daily. The primary endpoint was independent review committee (IRC)-assessed objective response rate per RECIST v1.1. 113 patients were enrolled and received at least one dose of fluzoparib. As of data cutoff on March 21, 2020, the median follow-up period was 15.9 months (IQR 13.5-18.5). The IRC- and investigator-assessed objective response rates were 69.9% (95% CI 60.6-78.2) and 70.8% (95% CI 61.5-79.0), respectively. The objective response rates were similar across all pre-specified subgroups. The median IRC- and investigator-assessed progression-free survival was 12.0 months (95% CI 9.3-13.9) and 10.3 months (95% CI 9.2-12.0), respectively. The 12-month survival rate was 93.7% (95% CI 87.2-96.9). Grade {greater than or equal to}3 adverse events occurred in 63.7% (72/113) of the patients, with the most common one being anaemia/decreased haemoglobin. Adverse events that led to treatment interruption, dose reduction, and discontinuation occurred in 39.8%, 34.5%, and 0.9% of patients, respectively. One treatment-related death occurred. Fluzoparib demonstrated promising anti-tumor activity and acceptable safety profile in germline BRCA1/2-mutated, platinum-sensitive relapsed ovarian cancer. Thus, fluzoparib might be a novel treatment option for this population. Clinical Trial number: NCT03509636. Copyright ©2021, American Association for Cancer Research.
