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). 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 (VEGF) therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every four to 12 weeks in frequency, to maintain efficacy. Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time. ABBV-RGX-314 is being developed as a potential one-time treatment for wet AMD.
