GAINESVILLE, Fla.--(BUSINESS WIRE)--Applied Genetic Technologies Corporation, a privately-held, clinical stage biotechnology company developing novel systems to deliver human therapeutics, announces that it has received a grant of $1.5 million from the Foundation Fighting Blindness to fund a pre-clinical trial evaluating the safety and efficacy of a gene therapy treatment for X-linked Retinoschisis (XLRS), a genetic eye disease affecting over 35,000 patients in the US and Europe. The work is being coordinated by AGTC in collaboration with researchers at Oregon Health & Science University Casey Eye Institute, Dr. David Wilson and The University of Florida, Dr. William Hauswirth. The grant is part of the Foundation Fighting Blindness’ effort to fund research projects with strong potential to enter into human clinical trials within three years.
“Translating the advances in genetics of eye disease to potentially curative treatments provides hope to the patients and families affected by these conditions,” says Dr. David Wilson, Director, Casey Eye Institute. “We are delighted to be partnering with AGTC and FFB in what is the most exciting and meaningful work being done in ophthalmology and medicine at this time.”
“AGTC’s emerging gene therapy is an elegant approach to treating a devastating retinal disease like XLRS, because one treatment may last several years or even a lifetime,” says Stephen Rose, Ph.D., chief research officer, Foundation Fighting Blindness. “Furthermore, AGTC has the production resources, clinical development knowledge, and regulatory expertise to move this promising approach through clinical trials once proof of principle is established in the laboratory.”
“We are thrilled that the FFB and its grant reviewers recognize AGTC’s expertise in development of treatments for rare genetic diseases and our ongoing commitment to ophthalmology patients,” said Sue Washer, President and CEO of AGTC. “This funding will enable us to finish final testing of the treatment in animal models of XLRS as well as complete the pre-clinical safety studies required by the FDA in order to start a Phase 1 human clinical trial. The ultimate goal is to improve these patients’ quality of life; there is currently no treatment available for the thousands of young boys losing their sight due to XLRS.”
XLRS, an inherited genetic condition, is a leading cause of juvenile macular degeneration in males. It is caused by mutations in a gene, called RS1, which results in splitting of the layers of the central retina. Patients typically begin to experience progressive loss of vision between the ages of 5 and 10, and other early symptoms include the inability to focus both eyes and roving, involuntary eye movements. No treatment for XLRS is currently available. AGTC’s potential treatment uses an adeno-associated virus (AAV) — a safe, manmade virus — that delivers healthy copies of the XLRS gene to the cells of the retina, replacing the defective copies of the gene. A single treatment can halt the disease for several years, perhaps a lifetime. The AAV delivery system is successfully being used in clinical trials of Leber congenital amaurosis gene therapy that have restored vision in more than 40 adults and children who were virtually blind.
About AGTC: AGTC is focused on the clinical development of novel therapeutics for patients with unmet medical needs utilizing its proprietary, non-pathogenic adeno-associated virus (AAV) delivery system. AGTC has demonstrated that this system can be used to deliver a normal form of a gene in both animals and humans, thus allowing their own bodies to produce sustained therapeutic levels of important biologics. The Company’s most advanced programs in development are treatments for Alpha-1 antitrypsin deficiency, a disease causing a progressive loss of lung function, and Leber’s congenital amaurosis, an inherited condition causing early blindness. Both utilize AGTC’s proprietary AAV system and production methods. AGTC has licensed a significant portion of its intellectual property from the University of Florida where researchers originated this groundbreaking work, and has received significant financing from some of the world’s leading venture capital firms: InterWest Partners, Intersouth Partners and MedImmune Ventures.

About The Foundation Fighting Blindness: The Foundation Fighting Blindness is a national nonprofit driving blindness research that will lead to preventions, treatments and cures for retinitis pigmentosa, macular degeneration, Usher syndrome and the entire spectrum of retinal degenerative diseases that affect 10 million Americans. In its 40-year history, the Foundation has raised more than $425 million as the leading non-governmental funder of retinal research. With a network of 50 chapters, the Foundation also provides free disease information and low vision resources to affected individuals and their families. Most recently, a breakthrough Foundation-funded study using gene therapy restored significant vision in children and young adults who were previously blind, paving the way for using this method to treat a wide variety of retinal degenerative diseases, and proving a cure is in sight.
