Researchers are evaluating the experimental drugs pozelimab and cemdisiran for treating Geographic Atrophy GA, a late stage of Age-related Macular Degeneration AMD that affects central vision. The study aims to compare the progression rate of GA in patients receiving cemdisiran alone, the combination of pozelimab and cemdisiran, or a placebo. Additional goals include monitoring side effects, drug levels in the blood over time, and the bodys antibody response to these drugs. Participants will receive subcutaneous injections of either pozelimab combined with cemdisiran, cemdisiran alone, or a placebo. The study is randomized and double-masked with three groups receiving different treatments. Treatment and monitoring will continue through specified time points up to 104 weeks, with follow-up on safety and antibody responses extending even further. During the study, participants will attend regular clinic visits for eye exams, imaging using Fundus Autofluorescence to measure GA lesion growth, vision tests including visual acuity and contrast sensitivity, and blood tests to assess drug levels and antibody formation. Researchers will track treatment-emergent adverse events and evaluate changes in vision and GA progression over time. Participation lasts until the study completion date in April 2033, with primary outcomes assessed at 52 weeks and further evaluations up to 296 weeks.

Researchers are observing how avacincaptad pegol is used in routine clinical practice for people with geographic atrophy caused by age-related macular degeneration AMD. Geographic atrophy is an advanced form of AMD where retinal cells waste away, leading to worsening central vision and potential permanent vision loss. This observational study collects information on treatment and medical events related to avacincaptad pegol without influencing the doctors treatment decisions. Participants in this study have chosen to begin treatment with avacincaptad pegol, delivered as intravitreal injections into the eye. The study records how often and how long the treatment is given, along with reasons for stopping treatment. It monitors participants receiving this treatment in one or both eyes as part of their regular medical care, without additional interventions from the study. During the study, participants will have eye exams as part of their usual care and will complete surveys about their eye health at the start of treatment, every six months for two years, and then yearly. Researchers will gather data from medical records to track treatment usage, vision changes, and any adverse events for up to about five years. This long-term observation helps understand real-world treatment patterns and safety.
