ROCKVILLE, Md., July 8, 2022 /PRNewswire/ -- REGENXBIO Inc. (Nasdaq: RGNX) today announced it has completed enrollment in Cohort 5 of the Phase II AAVIATE® trial of RGX-314 for the treatment of wet age-related macular degeneration (wet AMD) using in-office suprachoroidal delivery. “We are encouraged by the excellent progress we have made advancing RGX-314 suprachoroidal delivery in both our AAVIATE and ALTITUDE™ trials for the treatment of wet AMD and diabetic retinopathy,” said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO. “RGX-314, has the potential through delivery to the suprachoroidal space to offer the millions of patients facing vision loss from these retinal diseases with a one-time, in-office treatment option. We plan to present additional suprachoroidal data this year.” Results from Cohort 1 of the Phase II ALTITUDE trial of RGX-314 for the treatment of diabetic retinopathy were presented at the Angiogenesis, Exudation, and Degeneration 2022 conference and will be encored at the upcoming American Society of Retina Specialists Annual Meeting. AAVIATE Clinical Trial The multi-center, open-label, randomized, active-controlled, dose-escalation Phase II AAVIATE trial is evaluating the efficacy, safety and tolerability of suprachoroidal delivery of RGX-314 in patients with wet AMD using the Clearside SCS Microinjector®. Twenty patients in Cohort 1 were randomized to receive RGX-314 at a dose level of 2.5x1011 genomic copies per eye (GC/eye) through one injection versus monthly 0.5 mg ranibizumab intravitreal injection at a 3:1 ratio. Twenty patients in Cohort 2 were randomized to receive RGX-314 at a dose level of 5x1011 GC/eye through two injections versus monthly 0.5 mg ranibizumab intravitreal injection at a 3:1 ratio. Cohort 3 is evaluating RGX-314 at the same dose level as Cohort 2 in 20 patients who are neutralizing antibody (NAb) positive. Cohort 4 is evaluating RGX-314 in 15 patients at a dose level of 1x1012 GC/eye and Cohort 5 is evaluating the same dose level of RGX-314 in 20 patients who are NAb positive. Patients in these cohorts did not receive prophylactic immune suppressive corticosteroids before or after administration of RGX-314. About RGX-314 RGX-314, being developed in collaboration with AbbVie, is being investigated as a potential one-time treatment for wet AMD, diabetic retinopathy, and other chronic retinal conditions. RGX-314 consists of the NAV® AAV8 vector, which encodes an antibody fragment designed to inhibit vascular endothelial growth factor (VEGF). RGX-314 is believed to inhibit the VEGF pathway by which new, leaky blood vessels grow and contribute to the accumulation of fluid in the retina. REGENXBIO is advancing research in two separate routes of administration of RGX-314 to the eye, through a standardized subretinal delivery procedure as well as delivery to the suprachoroidal space. REGENXBIO has licensed certain exclusive rights to the SCS Microinjector® from Clearside Biomedical, Inc. to deliver gene therapy treatments to the suprachoroidal space of the eye. About 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-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 repeated intraocular injections, to maintain efficacy. Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time. About REGENXBIO Inc. REGENXBIO is a leading clinical-stage biotechnology company seeking to improve lives through the curative potential of gene therapy. REGENXBIO’s NAV Technology Platform, a proprietary adeno-associated virus (AAV) gene delivery platform, consists of exclusive rights to more than 100 novel AAV vectors, including AAV7, AAV8, AAV9 and AAVrh10. REGENXBIO and its third-party NAV Technology Platform Licensees are applying the NAV Technology Platform in the development of a broad pipeline of candidates, including late-stage and commercial programs, in multiple therapeutic areas. REGENXBIO is committed to a “5x'25" strategy to progress five AAV Therapeutics from our internal pipeline and licensed programs into pivotal-stage or commercial products by 2025.
