A Clinical Effectiveness Study Examining the Efficacy and Safety of ONS-5010 in Subjects With Neovascular Age-related Macular Degeneration (AMD)

This research study will examine the safety and effectiveness of ONS-5010 in participants with AMD. The goal is to prevent vision loss by evaluating the effectiveness of ONS-5010 as compared with ranibizumab.
