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.
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…
Inclusion Criteria: * Metastatic breast cancer with deleterious somatic BRCA 1 or 2 mutations detectable by cell-free circulating tumor DNA, by CLIA certified clinical assay (including but not restricted to MGH-Snapshot cfDNA assay, Guardant360, Foundation One). The eligibility of a given assay and/or BRCA mutation could be discussed with the primary investigator (Dr. Vidula) and senior investigator (Dr. Bardia), who will provide the final discretion. * Patients with germline BRCA 1 or 2 mutations will not be eligible. * Patients with only a VUS (Variant of Unknown Significance), or non-funct…
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 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.
