A Phase II Clinical Trial of the PARP Inhibitor Talazoparib in BRCA1 and BRCA2 Wild Type Patients With Advanced Triple Negative Breast Cancer and Homologous Recombination Deficiency or Advanced HER2 Negative Breast Cancer or Other Solid Tumors With a Mutation in Homologous Recombination Pathway Genes
The aim of this single-arm phase 2 clinical trial is to evaluate the anti-cancer activity of Talazoparib (also known as BMN 673) in patients with advanced breast cancer with specific genetic or tumor genomic alterations. Patients with either triple-negative or HER2-negative breast cancer are eligible.

Primary outcomes
- Objective Response (OR) — up to 24 weeks
Objective response (OR) is a common measure of benefit. OR is defined as the number of participants who achieved complete response (CR) or partial clinical (PR), per the Response Evaluation Criteria in Solid Tumors (RECIST) Criteria (v1.1). RECIST Criteria are assessed by physical measurement; magnetic resonance imaging (MRI); computed tomography (CT), positron emission tomography (PET)-CT; and/or X-rays, as follows: * CR = Disappearance of all target and non-target lesions * PR = ≥30% decrease in the sum of the long diameter of target lesions * OR = CR+PR * Stable disease (SD) = Small changes that do not meet any of the above criteria * Progressive disease (PD) = ≥20% increase in long diameter of target lesions, and/or the appearance of any new lesion(s) The outcome is expressed as the number of participants that achieved either CR or PR within 24 weeks of the start of treatment, a number without dispersion.
