A Phase 2, 2-Stage, 2-Cohort Study of Talazoparib (BMN 673), in Locally Advanced and/or Metastatic Breast Cancer Patients With BRCA Mutation (ABRAZO Study)

The purpose of this trial is to study talazoparib (also known as BMN 673) in patients with locally advanced or metastatic breast cancer with a deleterious germline BRCA 1 or BRCA 2 mutation. Subjects will be assigned to either Cohort 1 or 2 based on prior chemotherapy for metastatic disease:

Cohort 1) Subjects who have previously responded to platinum-containing regimen for metastatic disease with disease progression > 8 weeks following the last dose of platinum; orCohort 2) Subjects who have received > 2 chemotherapy regimens and who have had no prior platinum therapy for metastatic disease
