Ranibizumab (Lucentis) versus Bevacizumab (Avastin) for the Treatment of Age-Related Macular Degeneration: An Economic Disparity of Eye Health.

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly, and the advent of anti-vascular endothelial growth factor agents (VEGF) has revolutionized treatment for neovascular AMD. Two of the most popular anti-VEGF agents, ranibizumab (Lucentis; Genentech/Roche) and bevacizumab (Avastin; Genentech/Roche), effectively treat neovascular AMD but have a substantial difference in price. Multiple level 1 trials have demonstrated that bevacizumab is noninferior to ranibizumab in the treatment of neovascular AMD and that both have similar safety profiles. The decision to use one drug over the other is multifactorial with influences from industry as well as individual physician biases. However, the additional billions spent on ranibizumab result in a large economic disparity that is not rationalized by cost effectiveness models.
