ALAMEDA, Calif.--(BUSINESS WIRE)--BioTime, Inc. (NYSE MKT:BTX), a clinical-stage biotechnology company developing and commercializing products addressing degenerative diseases, today announced that a poster presentation based on data from its Phase I/IIa clinical trial of OpRegen® in the advanced form of dry age-related macular degeneration (dry-AMD) will be presented at the Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) on Monday, May 8, 2017, in Baltimore, Maryland.
Details of the Poster Presentation are as follows:
Title: Phase I/IIa clinical trial of human embryonic stem cell (hESC)-derived retinal pigmented epithelium (RPE, OpRegen®) transplantation in advanced dry form age-related macular degeneration (AMD): interim results
Date/Time: May 8, 2017 from 3:45 PM to 5:30 PM
Poster Number: 2320 - B0274
Session Title: AMD translational studies and choroidal neovascularization
OpRegen®, is now being evaluated in a dose-escalating Phase I/IIa clinical study in patients with advanced dry-AMD accompanied by geographic atrophy. OpRegen® has received Fast Track designation from the FDA for treatment of the advanced form of dry-AMD. Details of the trial and about a patient’s eligibility are available at https://clinicaltrials.gov/ with the following Identifier: NCT02286089 (dry-AMD).
OpRegen® 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. 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 either 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.
BioTime, Inc. is a clinical-stage biotechnology company focused on developing and commercializing novel therapies developed from what the company believes to be the world’s premier collection of pluripotent cell assets. The foundation of BioTime’s core therapeutic technology platform is pluripotent cells that are capable of becoming any of the cell types in the human body. Pluripotent cells have potential application in many areas of medicine with large unmet patient needs, including various age-related degenerative diseases and degenerative conditions for which there presently are no cures. Unlike pharmaceuticals that require a molecular target, therapeutic strategies based on the use of pluripotent cells are generally aimed at regenerating or replacing affected cells and tissues, and therefore may have broader applicability than pharmaceutical products.
