- Documented germline mutation in BRCA1 or BRCA2 that is predicted to be deleterious or
suspected deleterious (known or predicted to be detrimental/lead to loss of function).

- Completed adequate breast and axilla surgery.

- Completed at least 6 cycles neoadjuvant or adjuvant chemotherapy containing
anthracyclines, taxanes or the combination of both. Prior platinum as potentially

treatment for breast cancer is allowed.

Key exclusion criteria
Exclusion criteria:

- Any previous treatment with a PARP inhibitor, including olaparib and/or known
hypersensitivity to any of the excipients of study treatment.

- Patients with second primary malignancy. EXCEPTIONS are:

1. adequately treated non-melanoma skin cancer, curatively treated in situ cancer of
the cervix, Ductal Carcinoma in situ (DCIS) of the breast, stage 1 grade 1
endometrial carcinoma

2. other solid tumours and lymphomas (without bone marrow involvement) diagnosed = 5
years prior to randomisation and treated with no evidence of disease recurrence
and for whom no more than one line of chemotherapy was applied.

- Concomitant use of known strong CYP3A inhibitors (e.g., itraconazole, telithromycin,
clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir,
saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (e.g.,

treatment is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents.

- Evidence of metastatic breast cancer
