Acucela to develop optogenetic technology to improve visual function in Retinitis Pigmentosa patients
SEATTLE, WA, USA I April 4, 2016 I Acucela Inc. (Tokyo: 4589) (“Acucela”), a clinical-stage ophthalmology company that specializes in identifying and developing novel therapeutics to treat and slow the progression of sight-threatening ophthalmic diseases, and The University of Manchester, UK (“UoM”), announced today an exclusive license agreement whereby Acucela will develop and commercialize UoM’s human rhodopsin based optogenetic gene therapy1 for the treatment of retinal degenerative disease, including Retinitis Pigmentosa (“RP”).
RP is an inherited retinal disease involving one or more gene mutations that cause a slow, progressive degeneration of photoreceptor cells, those cells of the eye that are responsible for capturing light and starting the process that leads to visual perception. Often beginning in childhood, RP patients most commonly first experience a loss of rod photoreceptors, affecting peripheral and night vision, followed by loss of cone photoreceptors, affecting color perception and central vision, ultimately leading to blindness. RP affects approximately 1 out of every 4,000 people in the US, Europe and Asia, and there is currently no effective treatment for this rare disorder.
If approved, this genetic mutation-independent therapy, initially developed by Dr. Jasmina Cehajic-Kapetanovic and Professors Robert Lucas and Paul Bishop at UoM, will utilize a viral vector2 to transduce the ON-bipolar cells3 of the retina with human rhodopsin, a light sensitive protein normally expressed in the rod photoreceptors. Under the control of a cell specific promoter4, this technology has been shown to be effective at restoring visual response in a mouse model of retinal degeneration. Additionally, rhodopsin’s biological mechanism imparts a relatively high level of light sensitivity for this type of therapy and as a human protein, may minimize any immunological impact. This optogenetic technology will be studied across a variety of genetic mutations in RP and related conditions, and as such may be useful as a “pan-RP” therapy that is mutation-independent. Acucela plans to ultimately evaluate the ability of this technology to restore some level of vision in patients who are legally blind.
“We are extremely excited to enter into this collaboration with The University of Manchester and to begin the important development work needed to unlock the potential of optogenetic gene therapy to improve visual function in patients who have lost much of their vision as well as their hope,” stated Dr. Ryo Kubota, MD, PhD, and Chairman, President and CEO of Acucela.
“Having observed a dramatic recovery in vision in a mouse model of RP, we are delighted at the prospect of working with Acucela towards restoring useful vision in patients with advanced hereditary retinal degenerations,” stated Dr. Paul Bishop, FRCOphth, PhD, Professor of Ophthalmology, University of Manchester.
The agreement was negotiated on behalf of The University of Manchester by its technology transfer office, UMIP. Director of Operations at UMIP, Dr. Rich Ferrie commented, “We are delighted to have entered into this license with Acucela, who we believe is the ideal partner to develop a gene therapy for RP based on the ground-breaking science of Professors Lucas and Bishop. The signing of this agreement represents a potentially pivotal moment and offers real hope for RP patients.”
1Optogenetics – Science of imparting light sensitivity to cells that were previously not light sensitive through transduction of those cells with a light-sensing protein.
2Viral vector – Vehicle used to insert the therapeutic gene into the treated cells.
3ON-bipolar cells – Retinal neurons connected to the rod photoreceptors, located in the inner nuclear layer of the retina.
4Promoter – Genetic regulatory sequence that controls the expression of the therapeutic gene in specific environments.
