ADVM-022 Intravitreal Gene Therapy for Wet AMD

ADVM-022 (AAV.7m8-aflibercept) is a gene therapy product developed for the treatment of neovascular (wet) age-related macular degeneration (wet AMD). Wet AMD is a serious condition and the leading cause of blindness in the elderly. The available therapies for treating wet AMD require life-long intravitreal (IVT) injections every 4-12 weeks to maintain efficacy. A one-time IVT administration of ADVM-022 has the potential to treat wet AMD by providing durable expression of therapeutic levels of intraocular anti-VEGF protein (aflibercept) and maintaining the vision of patients. ADVM-022 is designed to reduce the current treatment burden which often results in undertreatment and vision loss in patients with wet AMD receiving anti-VEGF therapy in clinical practice.

About this study

This open-label, multicenter, dose-ranging study will evaluate 2 dose levels in up to 30 subjects (15 per dose) with active choroidal neovascularization (CNV) secondary to AMD. Subjects who are under active anti-VEGF treatment and have demonstrated a meaningful response to anti-VEGF therapy will be considered for participation in this study. The primary endpoint for this study is safety and tolerability of ADVM-022. All subjects will continue to be assessed for 104 weeks following treatment with ADVM-022.
