Multicentre Study of Olaparib Maintenance Monotherapy in Platinum Sensitive Relapsed Non gBRCAm Ovarian Cancer Patients

Summary

The purpose of the study is to assess the efficacy and safety of single-agent olaparib as a maintenance treatment in patients with relapsed High Grade Serous Ovarian Cancer (including patients with primary peritoneal and/or fallopian tube cancer) or high grade endometrioid cancer who do not have known deleterious or suspected deleterious germline BRCA mutations (non-gBRCAm) and who had responded following platinum based chemotherapy
