NEW YORK and CLEVELAND, Ohio, May 04, 2022 (GLOBE NEWSWIRE) — Abeona Therapeutics Inc. (Nasdaq: ABEO), a fully-integrated leader in cell and gene therapy, today announced the presentation of new preclinical data on AAV204 at the Association for Research and Vision in Ophthalmology (ARVO) Annual Meeting, taking place on May 1-4, 2022 in Denver, CO and virtually on May 11-12, 2022. The data was featured in a poster presentation entitled “AAV204, a Novel AAV Capsid, Demonstrates Superior Macular Transduction Following Para-Retinal Administration in Non-Human Primates.”
AAV204, a novel adeno-associated virus (AAV) capsid from Abeona’s in-licensed AIM™ capsid library, has previously been shown to facilitate transduction of both the inner and outer retina after intravitreal administration in mice and non-human primates. The purpose of the current study was to evaluate in non-human primates transduction levels in the macula and optic nerve following administration of AAV204 directly into the vitreous of the eye by para-retinal administration, a recently-developed method, which unlike subretinal administration does not create a retinal detachment. AAV204.GFP or AAV8.GFP were administered to four non-human primate eyes and green fluorescent protein (GFP) expression was monitored using scanning laser ophthalmoscopy (SLO), followed by immunohistochemistry analysis at 28 days post-injection.
Results from this study showed that AAV204 induced high GFP expression in the macula and optic nerve as measured by SLO imaging and immunohistochemistry analysis, while AAV8-injected animals showed little to no GFP expression in the macula or optic nerve.
“The results presented at ARVO show that AAV204 is able to achieve high macular and optic nerve transduction levels with an administration route that is less invasive and safer than subretinal injection,” said Brian Kevany, Ph.D., Chief Technical Officer and Head of Research at Abeona. “Of note, the AAV204 dose used in this study was lower than those typically used for intravitreal injections and resulted in no clinically-relevant inflammation in any treated animals.”
About the AIM™ capsid library
Capsids from the AIM™ capsid library exclusively licensed by Abeona are novel AAV serotypes that target delivery of genetic payloads to the central nervous system (including the retina), lungs, eye, muscle, liver and other tissues with potentially improved tropism profiles key to enable treatment of a variety of devastating diseases. AIM™ vectors have shown the potential to evade the immune response generated by exposure to naturally-occurring AAV vectors. AAV204 is covered by U.S. Patent Nos. 10,532,110 and 10,561,743.
