Evaluation of Talazoparib, a PARP Inhibitor, in Patients With Somatic BRCA Mutant Metastatic Breast Cancer: Genotyping Based Clinical Trial
Study Overview
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.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
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 must have evaluable or measurable disease.
- Any number of prior lines of therapy are allowed

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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Median Progression Free Survival
Time Frame: From the start of treatment until death or disease progression, up to approximately 2 years
|
Progression-Free Survival (PFS) is defined as the time from the first dose of study treatment to the date of disease progression as assessed by Response Evaluation Criteria in Solid Tumors (RECIST v1.1) or death due to any cause, whichever occurs first.
Disease progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).
In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
(Note: the appearance of one or more new lesions is also considered progression).
