AMD is the leading cause of severe vision loss in people over the age of 65 in the United States and other western countries. A quantity of documents indicate that neovascularization promoted by VEGF is the main cause of visual acuity decline. Patients are starving for a new drug which can notably improve VA with less administration frequency and lower treatment cost.~The new drug Recombinant Human VEGF Receptor-Fc Fusion Protein (KH902) is a gene fusion protein. The pre-clinical researches and phase II study showed that KH902 is well-tolerated,and safe, it is effective in inhibiting the growth, migration, pullulation of vascular endothelial cells and neovascularization induced by VEGF.~This study is designed to prove and confirm the efficacy and safety of multiple injections of KH902 in patients with choroidal neovascularization due to neovascular age-related macular degeneration by comparing intravitreal injections of KH902 with sham-injections.
