A phase II, randomized, multicenter study evaluating the combination of lapatinib and vinorelbine in women with ErbB2 overexpressing metastatic breast cancer.

ABSTRACT: Lapatinib is approved in combination with capecitabine for treatment of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) who have progressed on prior trastuzumab in the metastatic setting. Vinorelbine is an important chemotherapy option for MBC. We evaluated efficacy and safety of lapatinib plus vinorelbine, compared with lapatinib plus capecitabine, in women with HER2-positive MBC. In this open-label, multicenter, phase II study, eligible patients (N = 112) were randomized 2:1 to lapatinib plus vinorelbine [(N = 75) 1,250 mg orally once daily (QD) continuously plus 20 mg/m(2)/day intravenously] or lapatinib plus capecitabine [(N = 37) 1,250 mg orally QD continuously plus 2,000 mg/m(2)/day orally, 2 doses].
