Efficacy and Safety Trial of Conbercept Intravitreal Injection for Neovascular AMD (PANDA-2)

Stopped early · Phase 3

Conditions studied: Neovascular Age-related Macular Degeneration

In brief

The purpose of this clinical study is to evaluate the efficacy and safety of two different levels of conbercept intravitreal (IVT) injection as compared to the approved vascular endothelial growth factor (VEGF) antagonist active control, aflibercept intravitreal injection (2.0 mg/eye, Eylea®), in subjects with neovascular AMD.
