Brief Summary

In neovascular (wet) age-related macular degeneration (nAMD), the macula, or the part of the eye that provides the clear, detailed central vision, is being affected by abnormal blood vessel growth and leakage. This leakage affects the vision over time and can lead to severe blurriness or blinding. EXG102-031 was made to block the extra vessel formation which would lead to less leakage affecting the vision. Before EXG102-031 can be tested for its efficacy (if it makes vision better), it must be tested to see if it is safely tolerated to confirm it can continue to be studied in more patients with nAMD. This study is designed to fulfill the long-term safety monitoring of EXG102-031. Participants that enroll in this long-term follow-up study have been treated with EXG102-031 under the main study (EXG102-031-211).

Detailed Description

Age-related macular degeneration (AMD) is a major cause of blindness and visual impairment in older adults. The wet form of AMD, also called neovascular AMD (nAMD) usually causes faster vision loss than the dry form. The most common current treatments of nAMD are products that inhibit vascular endothelial growth factor (VEGF) (including ranibizumab (LUCENTIS®, Genentech) and aflibercept (EYLEA®, Regeneron) and are delivered by intravitreal injections at 4 to 16 week intervals and continued indefinitely. The Phase I, open-label, multiple-cohort, dose-escalation study designed to evaluate the safety and tolerability of EXG102-031 gene therapy in subjects with previously treated nAMD (EXG102-031-211). In the main study safety was assessed over 52 weeks after the administration of EXG102-031. This long-term follow-up study will assess safety for an additional 36 months for all participants enrolled in the main study. Participants will return to the clinic regularly for ocular assessments including assessment of whether supplemental therapy with aflibercept is needed.
