ADVM-022 Intravitreal Gene Therapy for Wet AMD

An Open Label Phase 1 Study of ADVM-022 (AAV.7m8-aflibercept) in Neovascular (Wet) Age-Related Macular Degeneration

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.

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.

Inclusion Criteria:

• Age ≥ 50

• Subjects must be under active anti-VEGF treatment for wAMD and received a minimum of 2 injections within 4 months prior to screening
• Demonstrated a meaningful response to anti-VEGF therapy
• Willing and able to provide consent

Exclusion Criteria:

• History of retinal disease in the study eye other than wet AMD
• Fibrosis or atrophy, retinal epithelial tear in the center of the fovea in the study eye, or any condition preventing visual acuity improvement
• History of retinal detachment (with or without repair) in the study eye
• History of vitrectomy, trabeculectomy, or other filtration surgery in the study eye
• Uncontrolled glaucoma in the study eye
• Any prior treatment with photodynamic therapy or retinal laser for the treatment of wet AMD and any previous therapeutic radiation in the region of the study eye
• Any previous intraocular or periocular surgery on the study eye within 6 months
• Acute coronary syndrome, myocardial infarction or coronary artery revascularization, CVA, TIA in the last 6 months
• Uncontrolled hypertension defined as average SBP ≥160 mmHg or an average DBP ≥100 mmHg
