skin that has undergone potentially curative therapy or in situ cervical cancer.


- Has known, untreated central nervous system (CNS) metastases and/or carcinomatous
meningitis.


- Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the trial, interfere with the subject's
participation for the full duration of the trial, or is not in the best interest of
the subject to participate, in the opinion of the treating investigator.


- Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.


- Is pregnant or breastfeeding, or expecting to conceive or father children within the
projected duration of the trial, starting with the screening visit through 7 months
after the last dose of trial treatment.


- Has a known history of Human Immunodeficiency Virus (HIV).


- Has known active Hepatitis B or Hepatitis C.


- Patients should not be on strong P-glycoprotein inhibitors.


- Patients should not be on any other anti-cancer therapy (chemotherapy, hormone
therapy, immunotherapy, or alternate investigational therapy).

Official Title  ICMJE Evaluation of Talazoparib, a PARP Inhibitor, in Patients With Somatic BRCA Mutant Metastatic Breast Cancer: Genotyping Based Clinical Trial
Brief Summary This research is to evaluate the effectiveness of Talazoparib as a potential treatment for metastatic breast cancer with a BRCA 1 or BRCA 2 mutation.
Detailed Description

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.

The U.S. Food and Drug Administration (FDA) has not approved talazoparib for the participants' specific disease but it has been approved for metastatic breast cancer with a germline (inherited) BRCA mutation.

Talazoparib is a study drug that inhibits (stops) the normal activity of certain proteins called "poly (ADP-ribose) polymerases" also called "PARPs". PARPs are proteins (made from genes which are part of your DNA) that are found in all normal and cancer cells that are involved in the repair of DNA. PARPs are needed to repair mistakes that can happen in DNA when cells divide. If the mistakes are not repaired, the defective cell will usually die and be replaced. Cells with mistakes in their DNA that do not die can become cancer cells. Cancer cells may be killed by a study drug, like talazoparib, that stops the normal activity of PARPs. In clinical trials, the use of talazoparib and other PARP inhibitors have shown that these drugs can reduce tumor size and slow tumor growth in some cancer patients with BRCA1 or BRCA2 mutations.

In this research study, the investigators are examining how effective talazoparib is in patients with metastatic breast cancer with a BRCA mutation in their tumor.
