Introduction: The use of targeted therapies in the treatment of advanced non-small-cell lung cancer (NSCLC) is increasing, especially as conventional chemotherapy affords relatively small benefits at a cost of increased toxicity. Two of the more established therapeutic targets in NSCLC are the vascular endothelial growth factor receptor (VEGFR) and epidermal growth factor receptor (EGFR). Vandetanib is an orally available inhibitor of VEGFR and EGFR signalling and is an attractive therapeutic agent owing to the simultaneous inhibition of both pathways.
Areas covered: This review encompasses the clinical efficacy, safety and tolerability of vandetanib in advanced NSCLC. Of particular interest are the randomized Phase III clinical trials, which did not show clinically significant overall survival benefit for vandetanib monotherapy or in combination with standard chemotherapy regimens.
Expert opinion: Vandetanib has anti-tumour activity in NSCLC, with improved objective responses and disease control. However, significant survival benefits were not demonstrated in Phase III clinical trials and at present vandetanib is not in further development for use in NSCLC.
