Study Design:	Allocation: Non-Randomized; Intervention Model: Parallel Assignment; Masking: No masking; Primary Purpose: Treatment
Conditions:	Ovarian Carcinoma Breast Cancer
Intervention:	Drug: AZD2281

Participant Flow

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 July 8, 2008 and efficacy and safety data were collected up to the data cut-off of March 26, 2010. Patients were enrolled at 6 centres in Canada. Of the 112 patients who gave informed consent 21 patients failed eligibility criteria or withdrew their consent and were not allocated to treatment.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The study enrolled both known BRCA mutation carriers and patients with unknown BRCA status. Those with unknown status at entry had to provide a DNA sample for BRCA. One participant in arm 4 discontinued before receiving study drug and is excluded from the safety analysis set mutation analysis. Study data are summarised by confirmed mutation status.

Reporting Groups

	Description
BRCA Positive Non-serous Ovarian	Patients with non-serous ovarian cancer who have a harmful mutation in the "breast cancer genes" BRCA1 or BRCA2. (Serous tumors are the most common subtype of ovarian cancer; other subtypes are grouped together as "non-serous" in this study).
BRCA Positive Serous Ovarian	Patients with serous ovarian cancer who have a harmful mutation in the "breast cancer genes" BRCA1 or BRCA2. (Serous tumors are the most common subtype of ovarian cancer).
BRCA Negative Non-serous Ovarian	Patients with non-serous ovarian cancer who do not have a harmful mutation in the "breast cancer genes" BRCA1 or BRCA2
BRCA Negative Serous Ovarian	Patients with serous ovarian cancer who do not have a harmful mutation in the "breast cancer genes" BRCA1 or BRCA2
BRCA Positive Non-triple Negative Breast	Patients with non-Triple negative breast cancer (non-TNBC) who have a harmful mutation in the "breast cancer genes" BRCA1 or BRCA2. Non-TNBC are cancers that have receptors for oestrogen, progesterone or Her2
BRCA Positive Triple Negative Breast	Patients with Triple negative breast cancer (TNBC) who have a harmful mutation in the "breast cancer genes" BRCA1 or BRCA2. TNBC are cancers that don’t have receptors for oestrogen, progesterone or Her2 (Some commonly used breast cancer treatments don’t work for TNBC)
BRCA Negative Triple Negative Breast	Patients with Triple negative breast cancer (TNBC) who do not have a harmful mutation in the "breast cancer genes" BRCA1 or BRCA2.
