MENLO PARK, Calif., April 30, 2019 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases, presented today for the first time preclinical data on sequentially dosing a contralateral eye with ADVM-022 gene therapy. The data presented today in a poster session at the Association for Research in Vision and Ophthalmology (ARVO) 2019 Annual Meeting in Vancouver, BC demonstrate that ADVM-022 can be administered safely to the second eye, 2 months after injection in the first eye.
“We are excited to show that the second eye injection with ADVM-022 can be performed safely at the time of peak immune response to this therapy injected into the first eye. It is encouraging to see that levels of expression in the second eye are still within the aflibercept therapeutic levels,” said Mehdi Gasmi, Ph.D., president and chief scientific officer of Adverum Biotechnologies. “The findings from this study highlight ADVM-022’s potential for the treatment of patients with pre-existing vector immunity or bi-lateral disease.”
Highlights from the poster included:
About ADVM-022 Gene Therapy Candidate for Wet AMD
Adverum’s gene therapy candidate for wet AMD, ADVM-022, utilizes a proprietary vector capsid (AAV.7m8) carrying an aflibercept coding sequence under the control of a proprietary expression cassette and is administered as a single intravitreal administration. ADVM-022 is designed to provide sustained therapeutic levels of aflibercept, minimize the burden of frequent anti-VEGF injections, and improve real-world vision outcomes for patients with wet AMD.
About Wet Age-related Macular Degeneration (Wet AMD)
Age-related macular degeneration (AMD) is a progressive disease affecting the retinal cells in the macula, the region of the eye responsible for central vision. Disease progression results in the death of retinal cells and the gradual loss of vision. Wet AMD is an advanced form of AMD, affecting approximately 10% of patients living with AMD. In patients with wet AMD, abnormal blood vessels grow underneath and into the retina. These abnormal blood vessels leak fluid and blood into and beneath the retina, causing vision loss. In most patients, wAMD develops in both eyes at different times.
Wet AMD is a leading cause of vision loss in patients over 60 years of age, with a prevalence of approximately 1.2 million individuals in the U.S. and 3 million worldwide. The incidence of new cases of wet AMD in the U.S. is approximately 150,000 to 200,000 annually, and this number is expected to grow significantly as the country’s population ages.
The standard-of-care therapy for wet AMD is anti-VEGF intravitreal injections. These are effective but typically require long-term eye injections every 4-8 weeks in order to fully maintain vision gains. Compliance with this regimen can be difficult for patients, caregivers, and healthcare systems, leading to suboptimal dosing and loss of vision from undertreatment.
