Study Details
Study Description
Brief Summary
This study is a retrospective, multi-site, patient-level medical chart review of US adult patients with locally advanced or metastatic breast cancer (ABC) who initiated talazoparib on or after October 16, 2018 and were managed by participating providers from Cardinal Health's Oncology Provider Extended Network (OPEN).
This study will describe patient characteristics, treatment patterns, and clinical outcomes of talazoparib-treated patients in real-world practice setting in US.
The primary population for this study includes:
-HER2-negative ABC patients with germline BRCA1/2 (gBRCA1/2) mutations treated with talazoparib monotherapy initiated on or after October 16, 2018 and ≥18 years of age at initiation of talazoparib.
