Confirmed Objective Tumour Response (According to RECIST Criteria) [ Time Frame: Baseline, every 8 also at study termination or initiation of confounding anti-cancer therapy. Up to 2 years. ]
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT/MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease from baseline in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Objective tumour response rate [ Time Frame: 4 months ]

  • Duration of Response to Olaparib [ Time Frame: Time from response (CR or PR) to progression per RECIST criteria ]
  • The Clinical Benefit Rate (CBR) [ Time Frame: End of study ]
    The Clinical Benefit Rate (CBR) is defined as the percentage of patients with a RECIST tumour response of confirmed CR, PR or stable disease (SD) for ≥8 weeks +/- 1 week visit window.
  • Best Percent Change in Tumour Size [ Time Frame: End of study ]
    The tumour size is defined as the sum of the longest diameters as measured among all target lesions.
  • Progression-Free Survival (PFS) [ Time Frame: End of study ]
    PFS is defined as the time from first dose to the earlier date of radiologic progression (as per RECIST criteria) or death by any cause in the absence of objective progression. Those patients who were withdrawn from the study without disease progression were regarded as censored at their last evaluable RECIST assessment. Where patients had not progressed at the termination of the study, they were also regarded as censored at their last evaluable RECIST assessment.
  • Change From Baseline in ECOG Performance Status: Improvement Rate [ Time Frame: At cycle 7 day 1 (ie, after completing 6 cycles of treatment) ]
    The change in ECOG performance status was defined as improved (meaning the ECOG score is less than the baseline value), no change (ECOG is same as at baseline), worsened (ECOG score is greater than the baseline value) or missing (the ECOG score is missing or was not recorded at baseline). If no measurement was recorded at Cycle 1 Day 1, the change was calculated in relation to the last recorded ECOG value prior to Day 1.
  • Clinical benefit rate [ Time Frame: every 2 months ]
  • Safety and tolerability profile [ Time Frame: assessed at each visit throught the study ]

Study to Assess the Efficacy and Safety of a PARP Inhibitor for the Treatment of BRCA-positive Advanced Breast Cancer
A Phase II Open-label, Non-comparative, International, Multicentre Study to Assess the Efficacy and Safety of KU 0059436 (Olaparib) Given Orally Twice Daily in Patients With Advanced BRCA1 or BRCA2 Associated Breast Cancer
The purpose of the study is to see if the drug KU 0059436 (olaparib) is effective and well tolerated in treating patients with measurable BRCA1- or BRCA2-positive advanced breast cancer and for whom no curative therapeutic option exists.
