A Phase II Randomized Study of Lapatinib Combined With Capecitabine, Vinorelbine, or Gemcitabine in Patients With HER2-Positive Metastatic Breast Cancer With Progression After a Taxane (Latin American Cooperative Oncology Group 0801 Study).

Background: Novel targeted agents and combinations have become available in multiple lines of treatment for human epidermal growth factor receptor 2-positive (HER2(+)) metastatic breast cancer (MBC). In this context, alternatives to the lapatinib (L) and capecitabine (C) regimen, evaluating L combined with other cytotoxic drugs, are warranted.

Patients And Methods: In the present phase II, multicenter study, patients with HER2(+) MBC with progression after taxane were randomized between L, 1250 mg, combined with C, 2000 mg/m(2) on days 1 to 14 (LC), vinorelbine (V), 25 mg/m(2) on days 1 and 8 (LV), or gemcitabine (G), 1000 mg/m(2) on days 1 and 8 (LG), every 21 days.

Vandetanib versus gefitinib in patients with advanced non-small-cell lung cancer: results from a two-part, double-blind, randomized phase ii study.

Purpose: Vandetanib is a once-daily oral inhibitor of vascular endothelial growth factor receptor (VEGFR) and epidermal growth factor receptor (EGFR) signaling. In this two-part phase II study, the efficacy and safety of vandetanib was compared with that of gefitinib, an inhibitor of EGFR signaling.

Patients And Methods: Patients (N = 168) with locally advanced or metastatic (stage IIIB/IV) non-small-cell lung cancer (NSCLC), after failure of first-line with or without second-line platinum-based chemotherapy, received once-daily vandetanib 300 mg (n = 83) or gefitinib 250 mg (n = 85) until disease progression or evidence of toxicity (part A).
