Abstract
Purpose Neratinib is an oral, irreversible pan-ErbB receptor tyrosine kinase inhibitor. The efficacy and safety of neratinib were evaluated in two cohorts of patients with advanced ErbB2-positive breast cancer—those with and those without prior trastuzumab treatment—in an open-label, multicenter, phase II trial. Patients and Methods Patients in the two cohorts (prior trastuzumab, n = 66; no prior trastuzumab, n = 70) received oral neratinib 240 mg once daily. The primary end point was the 16-week progression-free survival (PFS) rate for the evaluable population (prior trastuzumab, n = 63; no prior trastuzumab, n = 64), as assessed by independent review. Results The 16-week PFS rates were 59% for patients with prior trastuzumab treatment and 78% for patients with no prior trastuzumab treatment. Median PFS was 22.3 and 39.6 weeks, respectively. Objective response rates were 24% among patients with prior trastuzumab treatment and 56% in the trastuzumab-naïve cohort. The most common adverse events were diarrh...
