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

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

• Concomitant use of known strong CYP3A inhibitors and strong (or moderate CYP3A inducers

• Persistent toxicities (≥ Grade 2 Common Terminology Criteria for Adverse Event (CTCAE) adverse event) caused by previous cancer therapy, excluding alopecia

• Patients with myelodysplastic syndrome (MDS)/acute myeloid leukaemia (AML) or with features suggestive of MDS/AML
