Intravitreal aflibercept for neovascular age-related macular degeneration.

Neovascular age-related macular degeneration (AMD) is the leading cause of legal blindness in patients over the age of 50 in the western world. Intravitreally administered anti-VEGF drugs have been developed to halt neovascular growth in AMD. Randomized trials have demonstrated the excellent safety profile and significant benefit of anti-VEGF therapy in maintaining vision. Aflibercept (Eylea(®); Regeneron, NY, USA) is a soluble decoy receptor against VEGF that offers greater potency and binding affinity than other anti-VEGF drugs. Having received US FDA approval for neovascular AMD in November 2011, aflibercept given every 8 weeks after a loading dose was 'clinically equivalent' and statistically noninferior to the current FDA-approved therapy ranibizumab (Lucentis(®); Genentech, CA, USA), given every 4 weeks. This article discusses the clinical background of AMD, development of aflibercept, results of the clinical trials and the future role of aflibercept in ocular neovascular diseases.
