This Phase 2, multi-center, randomized, double-masked, parallel group study is designed to evaluate the safety, tolerability, and efficacy of a single IVT injection of ADVM-022 at one of two doses (2 × 10^11 vg/eye [2E11] or 6 × 10^10 vg/eye [6E10]) accompanied by one of four prophylactic corticosteroid treatment regimens.~Up to 72 anti-VEGF treatment-experienced study participants meeting the eligibility criteria will be randomized between the 2E11 vg/eye and 6E10 vg/eye ADVM-022 doses each with 4 prophylaxis arms for a total of 8 treatment arms, and only one eye per study participant will be selected as the study eye.~Safety, tolerability, and efficacy will be evaluated for a period of approximately 1 year from baseline.
Neovascular or wet age-related macular degeneration (nAMD) is a degenerative ocular disease associated with the infiltration of abnormal blood vessels in the retina from the underlying choroid layer and is a leading cause of blindness in patients over 65 years of age. The abnormal angiogenic process in nAMD is stimulated and modulated by vascular endothelial growth factor (VEGF). Treatment of nAMD requires frequent intravitreal (IVT) injections of VEGF inhibitors (anti-VEGF) administered every 4-16 weeks. ADVM-022 (AAV.7m8-aflibercept) is a gene therapy product being developed for the treatment of nAMD and offers the potential for sustained intraocular expression of aflibercept following a single IVT injection. ADVM-022 is designed to reduce the current treatment burden which often results in undertreatment and vision loss in patients with nAMD receiving anti-VEGF therapy in clinical practice.
