Eligibility
Key inclusion criteria
* Histologically or cytologically confirmed carcinoma of the breast
* Locally advanced breast cancer that is not amenable to curative radiation or surgical cure and/or metastatic disease appropriate for systemic single cytotoxic chemotherapy
* Documentation of a deleterious, suspected deleterious, or pathogenic germline BRCA1 or BRCA2 mutation from Myriad Genetics or other laboratory approved by the Sponsor
* No more than 3 prior chemotherapy-inclusive regimens for locally advanced and/or metastatic disease (no limit on prior hormonal therapies or targeted anticancer therapies such as mechanistic target of rapamycin (mTOR) or CDK4/6 inhibitors, immune-oncology agents, tyrosine kinase inhibitors, or monoclonal antibodies against CTL4 or VEGF)
* Prior treatment with a taxane and/or anthracycline in the neoadjuvant, adjuvant, locally advanced, or metastatic setting unless medically contraindicated
* Have measurable or non-measurable, evaluable disease by the revised response evaluation criteria in solid tumors (RECIST) v.1.1
* Eastern Cooperative Oncology Group (ECOG) performance status = 2
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* First-line locally advanced and/or metastatic breast cancer with no prior adjuvant chemotherapy unless the Investigator determines that one of the 4 cytotoxic chemotherapy agents in the control arm would otherwise be offered to the subject
* Prior treatment with a PARP inhibitor (not including iniparib)
* Not a candidate for treatment with at least 1 of the treatments of protocol-specific physician's choice (ie, capecitabine, eribulin, gemcitabine, vinorelbine)
* Subjects who had objective disease progression while receiving platinum chemotherapy administered for locally advanced or metastatic disease; subjects who received low-dose platinum therapy administered in combination with radiation therapy are not excluded
* Subjects who have received platinum in the adjuvant or neoadjuvant setting are eligible; however, subjects may not have relapsed within 6 months of the last dose of prior platinum therapy
* Cytotoxic chemotherapy within 14 days before randomization
* Radiation or anti-hormonal therapy or other targeted anticancer therapy within 14 days before randomization
* HER2 positive breast cancer
* Active inflammatory breast cancer
* CNS metastases

* Exception: Adequately treated brain metastases documented by baseline CT or MRI scan that has not progressed since previous scans and that does not require corticosteroids (except prednisone = 5 mg/day or equivalent) for management of CNS symptoms. A repeat CT or MRI following the identification of CNS metastases (obtained at least 2 weeks after definitive therapy) must document adequately treated brain metastases.
* Subjects with leptomeningeal carcinomatosis are not permitted
* Prior malignancy except for any of the following:

* Prior BRCA-associated cancer as long as there is no current evidence of the cancer
* Carcinoma in situ or non-melanoma skin cancer
* A cancer diagnosed and definitively treated = 5 years before randomization with no subsequent evidence of recurrence
* Known to be human immunodeficiency virus positive
* Known active hepatitis C virus, or known active hepatitis B virus
* Known hypersensitivity to any of the components of talazoparib
