Annexon to Present on the Neuroprotective Effects of ANX007 at the 2025 ARVO Annual Meeting and the Retina World Congress

Core Insights - Annexon, Inc. announced positive Phase 2 ARCHER trial results for ANX007, a novel therapy aimed at preserving vision in patients with dry age-related macular degeneration (AMD) and geographic atrophy (GA) [1][2][3] - The company is preparing for a Phase 3 trial, ARCHER II, which will enroll approximately 630 patients globally [1][10] Group 1: ANX007 and Its Mechanism - ANX007 is a first-in-kind, non-pegylated antigen-binding fragment designed to inhibit C1q locally in the eye, addressing neurodegeneration caused by classical complement pathway activation [3][4] - The therapy has shown significant vision preservation in clinical endpoints such as best corrected visual acuity (BCVA) and low luminance visual acuity (LLVA) [3][6] - ANX007 has received Fast Track designation from the FDA and Priority Medicine (PRIME) designation in the EU, indicating its potential therapeutic advantage [5] Group 2: Clinical Trial Results - In the Phase 2 ARCHER trial, ANX007 demonstrated statistically significant protection against vision loss, with a time and dose-dependent effect observed [6][8] - The treatment effect was maintained during a six-month off-treatment period, suggesting a durable benefit [8] - ANX007 was well-tolerated, with no increase in choroidal neovascularization rates or retinal vasculitis events reported [8] Group 3: Future Developments - The Phase 3 ARCHER II trial aims to prevent ≥15-letter loss of BCVA, a well-established functional endpoint for ophthalmology drug approvals [10] - Topline data from the ARCHER II trial is expected in the second half of 2026 [10] - The trial will further assess safety and visual function outcomes, including low-luminance visual acuity and photoreceptor integrity [10]
