About this trial

This is a Phase III, randomized, open-label, active-controlled study to evaluate the efficacy and safety of subretinal injection of LX102 in participants with neovascular age-related macular degeneration. The study will evaluate a single subretinal injection of LX102 compared to an active comparator. The primary endpoint of this study is the mean change from D0 in BCVA based on an average at weeks 48 and 56.
