What this trial studies

This is a randomized, double-blind, comparative study that evaluates the efficacy, safety, pharmacokinetics, and immunogenicity of GNR-067, a biosimilar to Lucentis®, in patients with neovascular (wet) age-related macular degeneration. The study aims to enroll 408 patients aged 50 years and older who have been diagnosed with this condition. Participants will receive either GNR-067 or Lucentis® through intraocular injection, and their responses will be monitored to determine the effectiveness and safety of the treatments. The ultimate goal is to register GNR-067 for use in the Russian Federation.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 50 years and older with untreated neovascular (wet) age-related macular degeneration.

Not a fit: Patients with other forms of age-related macular degeneration or those who have previously received treatment for neovascular ARMD may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients suffering from wet age-related macular degeneration.

How similar studies have performed: Other studies have shown success with similar approaches in treating wet age-related macular degeneration, indicating potential for GNR-067.
