The abstract accepted for paper presentation is titled, “Phase 1 and 2a Study of Human Embryonic Stem Cell–Derived Retinal Pigment Epithelial Cells Transplanted Subretinally in Advanced Dry-Form AMD Patients.” The data will be presented by Dr. Oscar Cuzzani MD PhD, BioTime’s Vice President of Clinical Development. With more than 30 years of experience as a physician and in clinical development, Dr. Cuzzani has a wealth of experience practicing retinal surgery, and has held senior level positions working at some of the best research organizations including the National Eye institute and the
“The clinical work that our team, along with the principal investigators and other leading ophthalmologists, is conducting is of great importance for the millions of patients suffering from this debilitating disease and leading cause of blindness among the elderly population,” commented

OpRegen®, which is being studied for the treatment of the dry form of age-related macular degeneration (AMD), consists of a suspension of Retinal Pigment Epithelial (RPE) cells that are delivered subretinally during a simple intraocular injection. RPE cells are essential components of the back lining of the retina, and function to help nourish the retina including photoreceptors. A proprietary process that drives the differentiation of human pluripotent stem cells is used to generate high purity OpRegen® RPE cells. OpRegen® RPE cells are also “xeno-free," meaning that no animal products are used at any point in the derivation and production process. The avoidance of the use of animal products eliminates some potential safety concerns. Preclinical studies in rats have shown that following a single subretinal injection of OpRegen®, the cells can rapidly organize into its natural monolayer structure in the subretinal space and survive throughout the lifetime of the animal. OpRegen® is designed to be an “off-the-shelf” allogeneic (non-patient specific) product. Unlike treatments that require multiple, frequent injections into the eye, it is expected that OpRegen® would be administered in a single procedure. OpRegen® was granted Fast Track designation from FDA, which allows more frequent interactions with the agency, and eligibility for accelerated approval and priority review. OpRegen® is a registered trademark of Cell Cure Neurosciences Ltd., a majority-owned subsidiary of BioTime, Inc.
About Dry Age-Related Macular Degeneration (Dry-AMD)
Macular degeneration affects approximately 11 million people in the U.S. and is the leading cause of blindness in people over the age of 60. Approximately 90 percent of these patients suffer from the dry form, for which there are no FDA-approved therapies. In dry-AMD, there is a loss or dysfunction of the layer of retinal pigment epithelial (RPE) cells generally in the region of the eye called the macula, which is the part of the retina responsible for sharp, central vision that is important for facial recognition, reading and driving. These RPE cells support the light detecting photoreceptor cells that are so critical to vision. When we look at something, the photoreceptors (rods and cones) detect the light and send the information to the brain allowing us to perceive our surroundings. The age-dependent loss of the RPE cells therefore leads to degeneration of nearby photoreceptors and this can lead to severe vision loss or even legal blindness. Generally, the damage caused by the “dry” form is not as severe or rapid as that of the “wet” form. However, in the advanced stage of dry macular degeneration widespread loss of RPE and photoreceptors in the macular area, called geographic atrophy, leads to severe vision loss. While therapeutics are available to treat the wet form of AMD, there are currently no FDA-approved therapies for dry-AMD.
