Here we report the efficacy and safety results
from the experimental-therapy group of the I-SPY 2
trial that evaluated the tyrosine kinase inhibitor
neratinib (HKI-272; Puma Biotechnology), an irreversible
small-molecule inhibitor of the ErbB and
the human epidermal growth factor receptor (HER)
kinase family (epidermal growth factor receptor,
HER2, and HER4).
