StemCells, Inc. Announces Preclinical Results Showing Its Proprietary Human Neural Stem Cells Can Prevent Vision Loss
StemCells, Inc. (NASDAQ:STEM) reported today that its proprietary HuCNS-SC(R) product candidate (purified human neural stem cells), when transplanted into a well-established animal model, can protect the retina from progressive degeneration. Retinal degeneration leads to loss of vision in diseases such as age-related macular degeneration and retinitis pigmentosa. This promising study was conducted by Dr. Raymond Lund, a researcher and professor at the Casey Eye Institute at Oregon Health & Science University (OHSU) and his research team. Dr. Lund will present the study results at a seminar sponsored by the Foundation Fighting Blindness on Saturday, November 1, 2008. The seminar is scheduled to begin at 9:00 a.m. and will be held at the University of California - San Francisco, Cole Hall (Medical Sciences Building on Parnassus Campus) in San Francisco, California.
"This study confirms the results of previously published academic studies evaluating neural stem cell transplantation into the retina and provides us with the rationale to pursue clinical testing of HuCNS-SC cells for retinal disorders," said Stephen Huhn, MD, FACS, FAAP, Vice President and Head of the CNS Program at StemCells, Inc. "We are already conducting additional preclinical studies and a pre-IND meeting has been scheduled with the FDA for December of this year to determine the pathway to a successful IND filing."
"The HuCNS-SC cell has proven to have very robust survival, preserving vision in our rat model at time points beyond six months," commented Dr. Lund. "These data are very encouraging and suggest cell-based therapies for retinal degeneration can be a viable treatment approach."
Dr. Francis, a retina specialist and researcher, added, "I am excited by our burgeoning collaboration with StemCells. The results of the early preclinical studies support the potential for these cells to treat retinal degenerative disease. I am especially excited by the fact that the cell is currently being tested in a clinical trial for Batten disease, a disorder of the central nervous system, which should make the transition from the laboratory to clinical use in retinal disease that much easier."
Dr. Lund received his PhD in Anatomy from University College London, after which he joined the faculty and received tenure within two years. Shortly thereafter, he moved to the United States, joining the faculty at Stanford University. Throughout his career, Dr. Lund has held several impressive academic positions including Chair of the Anatomy Department at the Medical University of South Carolina, Chair of the Neurobiology and Anatomy Department at the University of Pittsburgh, chair of the Anatomy Department at the University of Cambridge in England, the Duke Elder Professorship at the Institute of Ophthalmology in London, and the Calvin and JeNeal Hatch Chair of Ophthalmology at the Moran Eye Center at the University of Utah. In 2005, he was appointed Vice Chair of research at the Moran Eye Center in Utah. In 2007, Dr. Lund was recruited to join the faculty of the Oregon Retinal Degeneration Center at the Casey Eye Institute.
Throughout his career, Dr. Lund's research has centered on the response of the central nervous system to injury and mechanisms of rescue and repair. Focusing on the retina and its connections with the brain, he pioneered eye transplants in mammals in the late 1970s. Currently, he is investigating the use of cell-based therapies for photoreceptor degeneration in animal models of human disease.
Dr. Francis is an ophthalmologist and retina specialist at the Casey Eye Institute, and an Associate Professor, Oregon Health & Science University. Dr. Francis received his MD from University of Southampton, Southampton, England, and his PhD in molecular genetics at the Institute of Ophthalmology in London. He co-directs the Casey Macular Degeneration and Oregon Retinal Degeneration Centers. His clinical and research interests have focused on age-related macular degeneration and inherited retinal disorders.
About Retinal Degeneration
The retina is a thin layer of neural cells that lines the back of the eye and is responsible for converting external light into neural signal processed by the brain. The loss of function in retinal cells leads to an impairment or loss of vision. The macula, one of the most critical parts of the retina, is responsible for processing detailed vision. The most common forms of retinal degeneration are age-related macular degeneration and retinitis pigmentosa. In the United States, age-related macular degeneration affects over 1.7 million people in the over-65 population and is the leading cause of blindness in that group. Retinitis pigmentosa is a class of hereditary diseases that also leads to progressive degeneration of retinal cells. In the United States, the most common types of retinitis pigmentosa affect approximately 65,000 people. Preventative measures for both age-related macular degeneration and retinitis pigmentosa have limited impact on the disease and current treatments are not curative.
About HuCNS-SC Cells
StemCells' lead product candidate, HuCNS-SC cells, is a purified composition of normal human neural stem cells that are expanded and stored as banks of cells. The Company's preclinical research has shown that HuCNS-SC cells can be directly transplanted; they engraft, migrate, differentiate into neurons and glial cells; and they survive for as long as one year with no sign of tumor formation or adverse effects. These findings show that HuCNS-SC cells, when transplanted, act like normal stem cells, suggesting the possibility of a continual replenishment of normal human neural cells.
About StemCells, Inc.
StemCells, Inc. is a clinical-stage biotechnology company focused on the discovery, development and commercialization of cell-based therapeutics to treat diseases of the central nervous system and liver. The Company's product development programs seek to repair or repopulate CNS and liver tissue that has been damaged or lost as a result of disease or injury. StemCells has pioneered the discovery and development of HuCNS-SC(R) cells, its highly purified, expandable population of human neural stem cells. StemCells has completed enrollment and dosing of a six patient Phase I clinical trial of its proprietary HuCNS-SC product candidate as a treatment for neuronal ceroid lipofuscinosis (NCL) and expects the trial to be completed in January 2009. NCL, which is often referred to as Batten disease, is a rare and fatal neurodegenerative disease that affects infants and young children. StemCells owns or has exclusive rights to more than 50 issued or allowed U.S. patents and more than 150 granted or allowed non-U.S. patents.
