2. Subject has histologically confirmed diagnosis of breast cancer per AJCC 8th edition meeting any of the following criteria: 1) triple negative, defined as ER/PR expression \<10% and HER2-negative, with any BRCA status; or 2) HER2-negative (with ER/PR expression \>=10% with germline or somatic BRCA mutation.
3. Subject has diagnosis of new brain metastasis by MRI, with a plan to undergo stereotactic radiosurgery (SRS) (up to 15 untreated metastases and at least 1 metastasis with maximum dimension \> 5mm). Patients are permitted to have undergone recent craniotomy and resection of metastasis/metastases if at least 1 other intact metastasis or gross residual tumor planned for definitive SRS is present. Patients may have had prior SRS as long as the previously treated brain metastases are stable and not planned for additional therapy. Re-irradiation of a lesion previously treated with SRS is not allowed. Discrete dural lesions are allowed.
4. Subject may have other sites of extracranial metastatic disease (does not need to be stable, as long as no signs of impending visceral crisis).
5. Subjects may have had prior systemic therapy other than combination DDR inhibitor (PARP inhibitor) and immune checkpoint inhibitor (i.e., prior PARP inhibitor without concurrent immune checkpoint inhibitor, or prior immune checkpoint inhibitor without concurrent PARP inhibitor, are allowed).
6. Subject has Eastern Cooperative Oncology Group (ECOG) performance status 0-2 within 28 days prior to registration.
7. Body weight \>30 kg (for durvalumab monotherapy or durvalumab combination).
8. Subject has life expectancy \> 16 weeks.
9. Age ≥ 18 years at the time of consent.
10. Prior systemic cancer treatment must be completed at least 7 days prior to treatment and the subject must have recovered from all reversible acute toxic effects of the regimen (other than alopecia) to Grade ≤ 1 or baseline.
11. Subject is willing and able to provide blood and tissue samples for correlative research activities, if applicable.
12. Patients must have normal organ and bone marrow function measured within 28 days prior to administration of study treatment as defined in the table below:

* Alanine aminotransferase (ALT) (Serum Glutamic Pyruvate Transaminase (SGPT)) Alanine aminotransferase (ALT) ≤ 2.5 × ULN unless liver metastases are present in which case, they must be ≤ 5x ULN
* International Normalized Ratio (INR) or Prothrombin Time (PT)
* Activated Partial Thromboplastin Time (aPTT) ≤ 1.5 × ULN; Patients taking warfarin may participate in this study; however, it is recommended that INR be monitored carefully at least once per week for the first month, then monthly if the INR is stable.
13. Postmenopausal or evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test within 28 days of study treatment and confirmed prior to treatment on Day 1. Postmenopausal is defined as:

15. Male patients must be willing to abstain from heterosexual activity or use a condom during treatment and for 3 months after treatment discontinuation. See the protocol for additional information.
16. As determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study.
* Patients with Grade ≥ 2 neuropathy will be evaluated on a case-by-case basis after consultation with the sponsor-investigator.

* Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
* Adequately treated carcinoma in situ without evidence of disease.

NOTE: Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody \[anti-HBc\] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA. Subjects with HIV/AIDS with adequate antiviral therapy to control viral load would be allowed if they are stable and have been on treatment for ≥ 4 weeks prior to first dose of study drug(s). Subjects with viral hepatitis with controlled viral load would be allowed while on suppressive antiviral therapy. Testing not required.
