Introduction:
Angiogenesis, the recruitment and growth of blood vessels, is a process central to the growth of solid tumors. One of the key mediators of angiogenesis is the vascular endothelial growth factor (VEGF) family of ligands. An antibody to VEGF-A, bevacizumab, has demonstrated a survival benefit in conjunction with platinum-based doublet chemotherapy in non-small-cell lung cancer (NSCLC). Aflibercept (VEGF Trap) is a recombinant VEGF receptor-antibody protein fusion with higher affinity for VEGF-A than bevacizumab, plus affinity for VEGF-B and placental growth factor (PlGF).
Areas Covered:
This article reviews recent clinical trials investigating the role of aflibercept in the treatment of lung cancer, both published in the literature and those for which preliminary data have been presented at major scientific meetings.
Expert Opinion:
Aflibercept has proven Phase III efficacy in metastatic colorectal cancer, but in lung cancer, large clinical trials have not yielded positive results. There remains hope that identification of biomarkers of response will one day help select patients most likely to benefit from antiangiogenesis therapy.
