300mg Olaparib or placebo tablets taken orally twice daily until objective radiological disease progression as per RECIST as assessed by the investigator (or as long as in the investigator's opinion they are benefiting from treatment and they do not meet any other discontinuation criteria).

The TOI ranges from 0-100 and a higher score indicates a higher HRQoL.

Assessed until 03 Feb 2020 DCO; up to a maximum of 75 months. ]To determine the efficacy of olaparib maintenance monotherapy compared to placebo in BRCA mutated high risk advanced ovarian cancer patients who are in clinical complete response or partial response following first line platinum based chemotherapy by assessment of time from randomization to first subsequent therapy or death (TFST).
- Efficacy of Olaparib by Time to Second Subsequent Therapy or Death (TSST) [ Time Frame: Time elapsed from randomization to second subsequent therapy or death. Assessed every 12 weeks following treatment discontinuation. Assessed until 03 Feb 2020 DCO; up to a maximum of 75 months. ]To determine the efficacy of olaparib maintenance monotherapy compared to placebo in BRCA mutated high risk advanced ovarian cancer patients who are in clinical complete response or partial response following first line platinum based chemotherapy by assessment of time from randomization to second subsequent therapy or death (TSST).
- Efficacy of Olaparib by Time From Randomization to Study Treatment Discontinuation or Death (TDT) [ Time Frame: Time elapsed from randomization to study treatment discontinuation or death. Assessed until 03 Feb 2020 DCO; up to a maximum of 75 months. ]To determine the efficacy of olaparib maintenance monotherapy compared to placebo in BRCA mutated high risk advanced ovarian cancer patients who are in clinical complete response or partial response following first line platinum based chemotherapy by assessment of time from randomization to study treatment discontinuation or death (TDT).

[ Time Frame: Radiologic scans performed at baseline then every ~12 weeks for the first 72 weeks, then every ~24 weeks thereafter, assessed until disease progression. Assessed until 19 Sep 2016 DCO. ]To assess efficacy of olaparib in patients identified as having a deleterious or suspected deleterious variant in either of the BRCA genes using variants identified with current and future BRCA mutation assays (gene sequencing and large rearrangement analysis).
- To Determine the Exposure to Olaparib by Pharmacokinetic Analysis [ Time Frame: Pharmacokinetics sampling to be performed in a subset of patients. Sampling times: Day 1 pre-dose & 1 hour; Day 15 pre-dose & 1 hour; Day 29 pre-dose. Assessed until 19 Sep 2016 DCO. ]To determine the exposure to olaparib in patients receiving olaparib maintenance monotherapy
