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 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.
from the San Antonio Breast Cancer Symposium, , 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.
