A Phase 3 Clinical Trial to Compare RBS-001 to Eylea® in Subjects With Neovascular Age-Related Macular Degeneration

ClinConnect Summary

This clinical trial is looking at a new treatment called RBS-001 for people with neovascular age-related macular degeneration (nAMD), a condition that can lead to vision loss. The purpose of the study is to see how well RBS-001 works compared to a standard treatment called Eylea®. Researchers will evaluate how effective each treatment is, how safe they are, and how well patients tolerate them.

To participate, individuals must be at least 50 years old and have a specific type of eye condition related to AMD that can be confirmed through special eye tests. Participants will need to provide informed consent, meaning they will be fully informed about the study before agreeing to join. The trial is not yet recruiting, but if you or someone you know is interested, it's important to discuss eligibility with a healthcare provider. Overall, participants can expect to receive either RBS-001 or Eylea® and will be carefully monitored throughout the study to ensure their safety and the effectiveness of the treatments.
