Brief Summary

This research is being done to evaluate the safety and tolerability of the new drug, axatilimab, in combination with olaparib (a standard of care treatment) in Breast Cancer 1/2 genes (BRCA 1/2) and PALB2 associated HER2-negative metastatic breast cancer. The names of the study drugs involved in this study are: * Axatilimab (a type of antibody) * Olaparib (a type of PARP inhibitor)

Eligibility Criteria

Inclusion Criteria: * Participants must have histologically or cytologically confirmed metastatic or unresectable HER2 negative breast cancer, including HER2 low (IHC 2+/ISH-, IHC 1+). Any ER and PR expressions are permitted but must be known. Patients with hormone receptor (HR) positive disease, defined by either ER and/or PR positivity, must have progressed or are intolerant to all available endocrine therapy regimens, or not candidates to further endocrine therapy-based approaches. * Documented germline or somatic mutation in BRCA1, BRCA2, or germline mutation in PALB2 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function). Testing may be completed by any CLIA-certified laboratory. * Participants must have evaluable or measurable disease per RECIST 1.1 criteria. NOTE: If the only site of measurable of disease has been previously irradiated, there must be evidence of post-radiation progression. * Patients must have
