Brief Summary:
Excessive vascular endothelial growth factor (VEGF) plays a key part in promoting neovascularization and edema in neovascular (wet) age-related macular degeneration (nAMD). VEGF inhibitors (anti-VEGF), including ranibizumab (LUCENTIS®, Genentech) and aflibercept (EYLEA®, Regeneron), have been shown to be safe and effective for treating nAMD and have demonstrated improvement in vision. However, anti-VEGF therapy is administered frequently via intravitreal injection and can be a significant burden to the patients. RGX-314 is a recombinant adeno-associated virus (AAV) gene therapy vector carrying a coding sequence for a soluble anti-VEGF protein. The long-term, stable delivery of this therapeutic protein following a 1 time gene therapy treatment for nAMD could potentially reduce the treatment burden of currently available therapies while maintaining vision with a favorable benefit:risk profile.
Detailed Description:
This Phase I/IIa, open-label, multiple-cohort, dose-escalation study was designed to evaluate the safety and tolerability of RGX-314 gene therapy in subjects with previously treated nAMD. Five doses were studied in approximately 42 subjects. Subjects who met the inclusion/exclusion criteria and had an anatomic response to an initial anti-VEGF injection received a single dose of RGX-314 administered by subretinal delivery. RGX-314 uses an AAV8 vector that contains a gene that encodes for a monoclonal antibody fragment which binds to and neutralizes VEGF activity. Safety was the primary focus for the initial 24 weeks after RGX-314 administration (primary study period). Following completion of the primary study period, subjects continued to be assessed until 104 weeks following treatment with RGX-314.
