Pivotal 1 Study of ABBV-RGX-314 (Also Known as RGX-314) Gene Therapy Administered Via Subretinal Delivery One Time in Participants With nAMD
This study tests ABBV-RGX-314, a one-time gene therapy treatment for wet age-related macular degeneration (AMD), a condition that causes vision loss due to abnormal blood vessel growth in the eye. The therapy is delivered directly under the retina during a single procedure. The goal is to determine if this treatment can help preserve or improve vision in people with wet AMD.
Key Objective:This trial is testing whether a single gene therapy injection can reduce the need for repeated eye injections and help preserve vision in people with wet AMD.
Who to Consider:People diagnosed with neovascular (wet) age-related macular degeneration who are interested in potentially reducing the burden of frequent treatment visits should consider enrolling.

Brief Summary
ABBV-RGX-314 (also known as RGX-314) is being developed as a novel one-time gene therapy for the treatment of neovascular (wet) age-related macular degeneration (wet AMD or nAMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-vascular endothelial growth factor (anti-VEGF) therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to maintain or prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every 4 to 16 weeks in frequency, to maintain efficacy. Due to the burden of these treatments, patients often experience a decline in vision with reduced frequency of treatment over time.
