Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The first patient was enrolled on 28 August 2008 and the last patient was enrolled on 9 February 2010. Patients were enrolled at 82 centres in 16 countries. Of the 326 patients enrolled, 265 were randomized

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
It was planned that 250 women with advanced platinum sensitive serous ovarian cancer who had received 2 or more previous platinum-containing regimens and demonstrated an objective stable maintained response in the last platinum regimen prior to enrolment were to receive olaparib 400 mg bd or matching placebo in a 1:1 ratio. 265 randomised.

Objective response to the last platinum containing regimen prior to enrolment on the study:

  • CR-Complete Response (defined as normal radiological findings and CA-125 within the normal range)
  • PR-Partial Response (defined as a RECIST PR and/or GCIG CA-125 response)



  Outcome Measures

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
For OM DoR: The subset of patients evaluable for response who responded to study treatment.Values in results table may be under-estimates as some patients had not progressed at final analysis,so true duration is likely to be greater than in database.
