In the North American VIEW 1 study, 96 percent of patients receiving VEGF Trap-Eye 0.5mg monthly, 95 percent of patients receiving VEGF Trap-Eye 2mg monthly, and 95 percent of patients receiving VEGF Trap-Eye 2mg every two months achieved maintenance of vision compared to 94 percent of patients receiving ranibizumab 0.5mg dosed every month. In the international VIEW 2 study, 96 percent of patients receiving VEGF Trap-Eye 0.5mg monthly, 96 percent of patients receiving VEGF Trap-Eye 2mg monthly, and 96 percent of patients receiving VEGF Trap-Eye 2mg every two months achieved maintenance of vision compared to 94 percent of patients receiving ranibizumab 0.5mg dosed every month. Visual acuity was measured as a score based on the total number of letters read correctly on the Early Treatment Diabetic Retinopathy Study (ETDRS) eye chart, a standard chart used in research to measure visual acuity, over 52 weeks. Maintenance of vision was defined as losing fewer than three lines (equivalent to 15 letters) on the ETDRS eye chart.
Ursula Schmidt-Erfurth, M.D., Professor and Chair of the Department of Ophthalmology at the University Eye Hospital in Vienna, Austria and the VIEW 2 Principal Investigator said, The currently available anti-VEGF therapies have significantly advanced the treatment of wet AMD, actually improving vision in many patients. However, monthly injections are required to optimize and maintain vision gain over the long-term. The results of the VIEW studies indicate that VEGF Trap-Eye could establish a new treatment paradigm for the management of patients with wet AMD — predictable every-other-month dosing without the need for intervening monitoring or dosing visits.
