AGTC Receives Grant from Food and Drug Administration for Clinical Study of Genetic Retinal Disease

Ongoing Phase II Trial tests ability to deliver sustainable treatment in patients with Leber congenital amaurosis (LCA) using proprietary AAV technology.

Gainesville, Florida. (September 13, 2010) 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 million from the Food and Drug Administration (FDA Orphan Drugs Program). The grant will fund a Phase II Human Clinical Trial evaluating the safety and efficacy of a treatment for Leber congenital amaurosis (LCA), a genetic retinal disease known to cause blindness at an early age. The clinical trial, coordinated by AGTC, is being conducted at The University of Massachusetts Medical School by Dr. Shalesh Kaushal and Oregon Health & Science University by Dr. Tim Stout.

“We are pleased that the FDA and its grant reviewers recognized AGTC’s expertise in clinical development of treatments for genetic retinal disease,” said Sue Washer, President and CEO of AGTC. “This funding will enable us to complete enrollment of the Phase 2 trial that is designed to deliver recombinant adeno-associated virus (rAAV) vectors to larger areas of the retina than in clinical studies performed to date. The ultimate goal of this research is to improve the sight and quality of life of patients affected by this disorder. We continue to be encouraged by the data from this and other trials supporting the ability of rAAV to provide sustained delivery and expression of therapeutic levels of many different biologics in the eye.”

"I am excited about the opportunity to offer my patients with LCA the opportunity to participate in this clinical trial.” said Tim Stout, M.D., vice president and professor of ophthalmology, Casey Eye Institute, OHSU School of Medicine. “The orphan program is an important mechanism that enables clinical development of these kinds of treatments."

LCA is an inherited form of retinal degeneration that usually presents as blindness or severely impaired vision at birth or during the first few months of life. Among the 3,000 patients with LCA in the United States, approximately 8 to 10% are caused by mutations in a single protein called RPE65. These patients have profound impairment of vision, but with the relatively preserved cellular structure necessary for successful gene therapy treatment. No treatment for LCA is currently available, but subretinal delivery of recombinant adeno-associated virus (rAAV) vectors expressing RPE65 has demonstrated substantial restoration of visual function in mouse and dog models of RPE65-associated blindness, and initial clinical trials in small numbers of patients have been encouraging.

About AGTC: AGTC is focused on the clinical development of novel therapeutics for patients with unmet medical needs utilizing AGTC’s 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 body 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 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 Casey Eye Institute: As part of Oregon Health & Science University, the Casey Eye Institute is an academic regional eye center. It is named after James and George Casey, founders of United Parcel Service. The Casey Eye Institute is also one of only seven regional eye research centers in the nation sponsored by Research to Prevent Blindness, the world's leading voluntary organization in support of eye research. The Casey Eye Institute has operated the Elks Children’s Eye Clinic since 1949, thanks to the generous support of the Oregon State Elks Association. www.ohsu.edu
