Brief Summary:
A Phase III, randomised, double-blind, placebo-controlled, multi-centre study to assess the efficacy of olaparib maintenance monotherapy in relapsed high grade serous ovarian cancer (HGSOC) patients (including patients with primary peritoneal and / or fallopian tube cancer) or high grade endometrioid cancer with BRCA mutations (documented mutation in BRCA1 or BRCA2 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function)) who have responded following platinum based chemotherapy.

Condition or disease Intervention/treatment Phase
Platinum Sensitive BRCA Mutated Relapsed Ovarian Cancer Following Complete or Partial Response to Platinum Based Chemotherapy Drug: Olaparib 300mg tablets Drug: Placebo to match olaparib 300mg Phase 3

Expanded Access : An investigational treatment associated with this study has been approved for sale to the public.   More info ...

Detailed Description:
Comparison of olaparib against a placebo in patients with ovarian cancer whose cancer has already improved by taking platinum based chemotherapy. The patients must also have a fault in their DNA which codes for the BRCA protein. The BRCA protein helps mend broken DNA in the cells of the body; if this protein doesn't work properly it can increase the chance of getting cancer. The aim of this study is to see whether patients taking olaparib tablets last longer until their cancer gets worse, compared to those taking the placebo tablet. The study is also looking to see if there is an overall improvement to how long the patients survive whilst taking olaparib tablets compared to the placebo tablets; and the quality of their life whilst living with ovarian cancer.
