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 June 15, 2007 and efficacy and safety data were collected up to the data cut-off of February 27, 2009. Patients were enrolled at 16 centres in 6 countries: Australia, Germany, Spain, Sweden, UK and the USA.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Two cohorts of up to 27 women with BRCA1- or BRCA2-associated breast cancer who had failed at least one prior chemotherapy and/or endocrine therapy in the advanced/metastatic setting, were assigned to receive olaparib 100 mg bd or 400 mg bd. Enrolment into the 2 cohorts was sequential with the 400 mg bd cohort being recruited first.
