tab014 compared to lucentis® in patients with neovascular age-related macular degeneration

Conditions: Neovascular Age-related Macular Degeneration

Summary: this study is a randomized, multi-center, double blind, lucentis controlled non-inferiority study in neovascular age-related macular degeneration patients. the objective of this study is to compare the efficacy and safety of tab014 and ranibizumab (lucentis).

primary objectives: to evaluate the efficacy of tab014 compared to lucentis in neovascular age-related macular degeneration patients secondary objectives: 1. to evaluate the safety of tab014 compared to lucentis in neovascular age-related macular degeneration patients. 2. to evaluate the immunogenicity of tab014 in neovascular age-related macular degeneration patients.
