SAN ANTONIO – In women with advanced HER2-negative breast cancer with germline BRCA mutations, talazoparib, an investigational oral PARP inhibitor, was associated with a near doubling in progression-free survival, compared with single-agent chemotherapy in the phase 3 EMBRACA trial.
After a median follow-up of 11.2 months, median progression-free survival by blinded central review was 8.6 months for patients assigned to receive talazoparib, compared with 5.6 months for patients randomized to receive the physician’s choice of either capecitabine, eribulin, gemcitabine, or vinorelbine.
In this video interview from the San Antonio Breast Cancer Symposium, Jennifer K. Litton, MD, from the University of Texas MD Anderson Cancer Center in Houston discusses the comparative efficacy of the drug relative to standard chemotherapy agents in this population, and the association of the PARP inhibitor with improved patient-reported quality of life outcomes.
The EMBRACA study was funded by Pfizer. Dr. Litton has disclosed research funding with EMD Serono, AstraZeneca, Pfizer, Genentech, and GlaxoSmithKline, and serves on advisory boards for Pfizer and AstraZeneca, all uncompensated.
