7. Males with partners of childbearing potential may be enrolled if they use a condom when having sex with a pregnant woman or with a woman of childbearing potential from 21 days before the first dose of study drug through 105 days after the last dose of study drug, and males should not donate sperm from the time point of study drug administration until at least 105 days thereafter.
8. Female patients must not be breastfeeding at screening and during the study participation until 45 days after the last dose of the study drug.
9. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.

Exclusion Criteria:

1. Treatment within 14 weeks or five half-live prior to dosing with any type of systemic anticancer therapy or any investigational agent, whichever is longer.
2. Major surgery within 8 weeks before screening.
3. Serious accompanying disorder or impaired organ function.
4. Symptomatic or impending spinal cord compression or cauda equina syndrome.
5. Non-healing wound, ulcer, or bone fracture, not including a pathological bone fracture caused by a pre-existent pathological bone lesion.

10. Known hypersensitivity to any of the talazoparib solution components.
11. Use of a strong P-gp inhibitor, strong P-gp inducer, or strong inhibitor of BRCP within 7 days or 5 half-lives, whichever is longer, before Day 1.
12. Any condition or reason that interferes with ability to participate in the study, causes undue risk, or complicates the interpretation of safety data, in the opinion of the Investigator or Sponsor (e.g. non-compliance, excessive alcohol consumption, intake of drugs of abuse unless these drugs are medically indicated \[e.g. opiates for pain relief\]).
