A Study to Evaluate Gene Therapy to Treat Neovascular Age-related Macular Degeneration

Overview

About this study

The primary objective of this study is to evaluate mean change in best-corrected visual acuity (BCVA) of RGX-314 relative to ranibizumab at Week 38.

Second objectives of this study are to evaluate the safety and tolerability of RGX-314 through Week 102, to evaluate the effect of RGX-314 relative to ranibizumab on BCVA, to evaluate the effect of RGX-314 relative to ranibizumab on central retinal thickness (CRT) as measured by spectral domain-ocular coherence tomography (SD-OCT), to evaluate the effect of RGX-314 relative to ranibizumab on center point thickness (CPT) as measured by SD-OCT, to assess the need for supplemental anti-vascular endothelial growth factor (VEGF) therapy in the RGX-314 treatment arms, to assess aqueous protein concentrations of RGX-314, and to evaluate the immunogenicity of RGX-314.

 

Participation eligibility
