Treat and Extend Dosing Regimen with Anti-vascular Endothelial Growth Factor Agents for Neovascular Age-related Macular Degeneration
American Journal of Ophthalmic Clinical Trials
Anti-vascular endothelial growth factor (anti-VEGF) agents are the mainstay of therapy for treatment of neovascular age-related macular degeneration (nvAMD), one of the leading causes of blindness in the developed world. There have been a variety of different treatment regimens that have been examined for the administration of anti-VEGF therapies, including continuous fixed dosing, pro re nata administration, and treat and extend (TAE) protocols. There is no clear consensus on which dosing
... n which dosing regimen optimizes visual and anatomical outcomes while accounting for factors such as cost and patient burden. Based on recent surveys in 2014 and 2017 by the American Society of Retina Specialists (ASRS), the majority of ophthalmology providers are utilizing TAE protocol for anti-VEGF dosing for the management of nvAMD. Although there are a number of clinical trials that have examined TAE dosing, the ALTAIR study is the first, large, prospective randomized controlled trial to compare two different TAE protocols utilizing the anti-VEGF agent aflibercept for nvAMD. The ALTAIR study, in conjunction with other previous clinical trials, suggests that TAE protocol with aflibercept is an effective anti-VEGF dosing regimen for patients with nvAMD as it produces good visual gains and minimizes cost and burden for the patient.
