- Histologically confirmed breast cancer or epithelial ovarian cancer (including fallopian tube or primary peritoneal cancer)
- Recurrent or metastatic disease for which talazoparib deemed an acceptable therapy by the investigator
- No more than 4 prior chemotherapy regimens for metastatic disease (no limit on prior hormonal therapies)
- Disease amenable to biopsy and willing to undergo mandatory biopsy at Screening and again at disease progression.
- Have sufficient archival formalin-fixed paraffin-embedded (FFPE) resected primary ovarian tumor tissue or sufficient archival core breast tumor tissue (1 slide with 5-µm-thick sections and 9 slides with 10-µm-thick sections, minimum 20% tumor cellularity). [Note: Fresh core breast tumor tissue may be used if archival tissue is not available.]
- Fresh tumor biopsy collected at Screening must be of sufficient quantity with minimum 25 mm2 surface area and 40 ?m thickness (eg, 2 mm x 15 mm core) and minimum two cores.
- Measurable disease per RECIST 1.1
- Eastern Cooperative Oncology Group (ECOG) performance status ?1
- Adequate organ function as defined below:
o Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ?2.5x upper limit of normal (ULN) [Note: ?5xULN if liver function abnormalities are due to hepatic metastasis]
o Total serum bilirubin ?1.5xULN [Note: ?3xULN for Gilbert's Syndrome]
o Calculated creatinine clearance ?30 mL/min
o Hemoglobin ?9.0 g/dL with last transfusion ?14 days before first study drug
o Absolute neutrophil count (ANC) ?1500/mm3
o Platelet count ?100,000/mm3
- Able to take oral medications
- Willing and able to provide written, signed informed consent after the nature of the study has been explained and prior to any study-related procedures
- If sexually active, willing to use acceptable method of contraception (eg, double-barrier) during treatment and for 30 days after last dose of study drug
- If females with childbearing potential, a negative serum pregnancy test at screening and willing to have additional serum and urine pregnancy tests during the study. [Note: Females without childbearing potential include those in menopause ?2 years, with tubal ligation ?1 year before screening, or with total hysterectomy.]
- Willing and able to comply with all study procedures

Primary Outcome Measures
NameTimeMethod
Main Objective: The primary objective is to determine a potential association between HRD score and objective tumor response to talazoparib (BMN 673) treatment.;Secondary Objective: Secondary objectives include safety, PK, and preliminary talazoparib (BMN 673) efficacy.;Primary end point(s): Objective response rate (ORR) according to revised Response Evaluation Criteria in Solid Tumors (RECIST 1.1) in patients with breast cancer and ovarian cancer.;Timepoint(s) of evaluation of this end point: Anticipated in about 24-30 months following first patient enrolled
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): Progression-free survival (PFS), Duration of response (DOR) for objective responders, and Gynecologic Cancer InterGroup (GCIG) CA125 response in patients with ovarian cancer;Timepoint(s) of evaluation of this end point: Anticipated in about 24-30 months following first patient enrolled
