PHASE2

RGX-314 Gene Therapy Administered in the Suprachoroidal Space for Participants With Diabetic Retinopathy (DR) With and Without Center Involved-Diabetic Macular Edema (CI-DME)

Sponsor: AbbVie

Summary

ABBV-RGX-314 is being developed as a novel, potential one-time gene therapy treatment for the treatment of Diabetic Retinopathy (DR) with and without Center-Involved Diabetic Macular Edema (CI-DME). DR is a chronic and progressive complication of diabetes mellitus. It is a sight-threatening disease characterized in the early stages by neuronal and vascular dysfunction in the retina, and later by neovascularization that leads to further deterioration of functional vision. Despite the availability of current treatments, diabetic retinopathy remains the leading cause of vision loss in working-age adults, those between the ages of 20 and 74. Existing treatment with anti-VEGF agents, although shown to be effective, are limited by short therapeutic half-lives, which then require frequent intravitreal injections over the patient's lifetime, resulting in increased risk of associated adverse events and significant treatment burden. Due to the burden of treatment, patients often do not closely adhere to treatment regimens and experience sub-optimal outcomes and a decline in vision.

Official title: A Phase 2, Randomized, Controlled, Dose-escalation Study to Evaluate the Efficacy, Safety, and Tolerability of RGX-314 Gene Therapy Delivered Via a Single Suprachoroidal Space (SCS) Injections in Participants With Diabetic Retinopathy (DR) With and Without Center Involved-Diabetic Macular Edema (CI-DME)(ALTITUDE)
