This is a Phase II study designed to assess efficacy and safety of talazoparib, high dose radiation, and atezolizumab in patients with metastatic TNBC that is PD-L1 positive. A total of 23 gBRCA pathogenic variant negative patients will be enrolled. All patients will be treated with induction talazoparib of 1mg PO daily starting Day 1. Patients will then receive 8 Gy x 3 fractions to 2-4 metastatic lesions beginning Day 12,13, or 14 and given QOD. 840 mg of atezolizumab will be given intravenously (IV) on Day 15 of the 1st cycle and then on Day 1 and Day 15 of the remaining cycles. The sequence of administration is not specified on the days in which talazoparib and atezolizumab are given on the same day. Each cycle equals 28 days. Treatment will continue until progression or severe toxicity.
A safety lead in of up to 6 patients will be performed. Immune-related and non-immune related adverse events will be tracked up to 12 weeks post initiation of atezolizumab, as the majority of treatment-related toxicities from talazoparib, radiation, and atezolizumab occur within this time period.

Inclusion Criteria:
Be willing and able to provide written informed consent/assent and HIPPA for the trial.
Ages 18-75 years old at time of consent. Female or male patients allowed.
ECOG PS of 0-2, KPS >/= 60%.
Biopsy proven metastatic triple negative breast cancer (estrogen receptor (</=10%), progesterone receptor (</=10%) and no overexpression of HER2 as evaluated by local institutions with at least 2 exracranial lesions of metastatic disease on imaging.
PD-L1 positive tumor infiltrate as defined as >/= 1% on IHC using the SP142 Ventana Assay.
Known gBRCA 1/2 status (gBRCA 1/2 negative [e.g. gBRCA wild-type, gBRCA variants of uncertain significance] are eligible).
Patients must have at least 1 extracranial metastatic lesion (may be measurable or non-measurable disease by RECIST v 1.1) that is amenable to high dose radiotherapy and at least one additional extracranial lesion of measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST v1.1) that will not receive radiotherapy on this study. Of note, lesions maybe in the same organ but must be 2 cm apart and breast lesions may be treated.
Patients must have received at least one and no more than three previous lines of systemic treatment in the advanced setting with or without immune therapy. Patients with disease recurrence or progression following neoadjuvant or adjuvant cytotoxic chemotherapy are not eligible unless they have received at least one line of chemotherapy with or without immune therapy in the advanced setting. NOTE: Targeted small molecules (e.g. tyrosine kinase inhibitors), hormonal agents and monoclonal antibodies that inhibit angiogenesis (e.g. bevacizumab, afilbercept) are not counted in the number of lines of therapy. Cytotoxic chemotherapy with or without immune therapy for advanced disease prior to protocol treatment is not permitted within 2 weeks of the protocol treatment. Patients may or may not have received radiotherapy or neoadjuvant or adjuvant chemotherapy in the treatment of their initial, non-metastatic breast cancer, but must be entered on study 2 weeks after their last dose of radiotherapy, last cycle of chemotherapy and biologic therapy (if applicable) for mTNBC and have sufficient resolution of side effects per physician assessment at time of talazoparib.
Demonstrate adequate organ function as defined in the table below. All screening labs to be obtained within 14 days prior to registration.
Patients must be eligible for radiotherapy, talazoparib, and atezolizumab.
Females of childbearing potential must have a negative serum or urine pregnancy test within 14 days prior to Cycle 1 Day 1. If a urine test is done and it is positive or cannot be confirmed as negative, a serum pregnancy test will be required. NOTE: Females are considered of child bearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are naturally postmenopausal for at least 12 consecutive months.
Women of childbearing potential and males must agree to use two effective methods of contraception or complete abstinence, from the time of signing the informed consent (females) or first day of study treatment (males), during the course of the study and for 7 months (females) and for 4 months (males) after the last dose of study drug.
Patients must not have active wound healing issues from surgery and sufficient resolution of surgical side effects, per physician assessment, at time of radiotherapy.
During participation on this study, no other investigation or commercial agents or therapy for cancer other than bisphosphonate, rank ligand inhibitors, atezolizumab, radiotherapy and talazoparib should be administered. NOTE: Patients may have received bisphosphonates or rank ligand inhibitors prior to and while on enrollment on study.
Patients must have the psychological ability and general health that permits completion of the study requirements and required follow up.
