Researchers are studying the effects of two experimental drugs, pozelimab and cemdisiran, in adults aged 50 to 85 who have Geographic Atrophy (GA) caused by Age-related Macular Degeneration (AMD), a condition that affects central vision. The study aims to compare how quickly GA progresses in patients treated with cemdisiran alone, a combination of pozelimab and cemdisiran, or a placebo. Additional goals include monitoring possible side effects, measuring drug levels in the blood, and checking for antibodies that might reduce drug effectiveness or cause side effects. Participants receive subcutaneous injections of either pozelimab combined with cemdisiran, cemdisiran alone, or a placebo. The study is randomized, double-masked, and placebo-controlled, conducted at multiple centers. Treatment schedules and dosing are managed as described in the protocol, with vaccinations for meningococcal and pneumococcal infections required prior to participation. Throughout the study, participants undergo regular clinic visits where eye imaging using Fundus Autofluorescence (FAF) tracks the progression of GA lesion area over 52 weeks. Researchers also monitor safety, side effects, and immune responses, ensuring adherence to study procedures. The main outcome measured is the growth rate of the GA lesion area over one year, helping to evaluate the potential benefits and risks of the study drugs.

This research aims to understand how avacincaptad pegol, a treatment approved in the US, is used for people with geographic atrophy caused by age-related macular degeneration (AMD). Geographic atrophy is an advanced stage of AMD where cells in the retina waste away, leading to worsening central vision and possible permanent vision loss. The study focuses on observing treatment patterns and safety in routine clinical practice rather than testing new effects. Participants in this study will receive avacincaptad pegol through intravitreal injections, which are injections into the eye. The study collects information from patients who have already been prescribed this treatment by their doctors. There is no experimental intervention from the study team, and treatment decisions are made by the patients' doctors. The study follows patients for up to 3 to 5 years, depending on when they join. While in the study, participants will have regular eye exams as part of their usual care. They will also complete surveys about their eye health at the start of treatment, every 6 months for the first 2 years, then annually afterward. Researchers will track treatment details like the number and dose of injections, treatment duration, reasons for stopping treatment, and patient characteristics. Safety and treatment patterns are monitored through medical records during and after treatment.
