An IDFS event is defined as the first occurrence of loco-regional or distant recurrence or new cancer or death from any cause.
pCR is defined as ypT0/Tis ypN0 (ie, no invasive residual in breast and the axillary lymph nodes on evaluation of the complete resected breast specimen and all sampled regional lymph nodes) following completion of neoadjuvant systemic therapy.
Phase I: frequency and severity of adverse events will be measured using common toxicity criteria for adverse events version 5.
Phase II: Intracranial disease control rate will be defined as the percentage of subjects with \[complete response (CR) + partial response (PR) + stable disease\] per RANO-BM criteria at 6 months after study treatment initiation.

| Olaparib | EXPERIMENTAL | Olaparib tablets 300mg b.i.d. p.o. |
| Placebo | PLACEBO_COMPARATOR | Placebo tablets b.i.d. p.o. |
| Cohort A | EXPERIMENTAL | Cohort A will consist of a lower-risk population of participants with HER2-negative ER-negative or ER-low defined as having a tumour size \>5 mm and ≤20 mm and N0 (T1b-c/N0). |
| Cohort B | EXPERIMENTAL | Cohort B will consist of a higher-risk population of participants with HER2-negative ER-negative or ER-low defined as having a tumour size of \>20 mm but ≤50 mm and N0 (T2/N0), or having a tumour size of \>1 mm but ≤20 mm and N1 (T1/N1). |
| Study Treatment Arm | EXPERIMENTAL | Cycle 1 of study treatment will consist of Olaparib twice daily concurrently with stereotactic radiosurgery (SRS). Olaparib will start one week prior to SRS and continue during and following SRS (1-5 fractions) for up to 28 days total. Once the subject has recovered from SRS, Cycle 2 will be initiated with physician's choice systemic therapy and durvalumab. Cycle 2+ will equal 21 days. During Cycles 2 and 3, physician's choice systemic monotherapy will be given along with durvalumab. Each cycle will last 21 days. Imaging to evaluate intracranial and extracranial disease will be performed after Cycle 3, and subjects with response will continue with the systemic therapy and durvalumab until progression (intracranial or extracranial), unacceptable toxicity or death. |
