BioTime Receives ISO 13485 Certification for Medical Devices

BioTime, Inc. (NYSE MKT: BTX) today announced that it has received ISO 13485:2003 certification from BSI (British Standards Institution) for design, development, manufacture, and distribution of BioTime HyStem® hydrogels for cell delivery applications.

BSI is currently one of the world’s largest independent certification bodies for quality management systems and ISO 13485:2003 is the world’s most recognized standard for quality management systems for medical devices, and is the most commonly chosen path for companies to meet the quality system requirements in Europe, Canada, Japan, Australia, and other countries.

ISO certification is a prerequisite for CE marking of medical devices within the European Union and this certification is an important milestone in BioTime’s development program for Renevia™, a cell delivery matrix scheduled to begin pivotal human clinical trials in 2014 at the Stem Center in Palma de Mallorca, Spain. In this first clinical application, Renevia™ will be used as a delivery matrix for autologous adipose cells to treat the facial lipoatrophy associated with HIV. Restoration of normal skin contour is an important quality-of-life issue with this chronic condition and BioTime believes that this cell-based therapy will offer fewer complications and a more natural like appearance compared to products currently available. It has been estimated that worldwide over 40% of individuals receiving long-term antiretroviral therapies suffer from this disfiguring condition. According to www.avert.org in 2011 there were approximately 800,000 persons living with HIV/AIDS in Western Europe. Globally the number exceeds 30 million.

If Renevia™ is approved for the treatment of HIV-related facial lipoatrophy, BioTime plans to seek to expand its uses into other cell-based applications in reconstructive surgeries, traumatic injuries, and age-related lipoatrophy. BioTime’s plan is to bring Renevia™to the medical market first in the European Union, where the regulatory pathway will allow for faster approval than in the United States. Once the use of Renevia™ is established in Europe, BioTime will address an even larger potential market in Asia and the United States.

William P. Tew, Ph.D., BioTime’s Chief Commercial Officer stated, “We are very pleased with our ISO Certification and BSI’s acknowledgement of our on-going commitment to quality. Our quality management systems will provide a solid foundation for our clinical, regulatory, manufacturing, and future commercial activities. While this present certification focuses on HyStem® hydrogels for cell delivery applications, should BioTime decide to pursue CE marks for other applications of its hydrogel technology we will expand the scope of our ISO certification.”

About HyStem®

BioTime’s HyStem® family of hydrogels are unique biomaterials that are designed as matrices and scaffolds in medical device, tissue engineering, and regenerative medicine applications. HyStem® hydrogels are distributed and sold worldwide by BioTime and its distributors for pre-clinical research. Clinical grade hydrogels are also available to support translational research and investigator initiated clinical studies. BioTime’s HyStem® technology is covered by two issued US patents with applications pending in the EU, Canada, Japan, and Australia.

About BioTime

BioTime is a biotechnology company engaged in research and product development in the field of regenerative medicine. Regenerative medicine refers to therapies based on stem cell technology that are designed to rebuild cell and tissue function lost due to degenerative disease or injury. BioTime’s focus is on pluripotent stem cell technology based on human embryonic stem (“hES”) cells and induced pluripotent stem (“iPS”) cells. hES and iPS cells provide a means of manufacturing every cell type in the human body and therefore show considerable promise for the development of a number of new therapeutic products. BioTime’s therapeutic and research products include a wide array of proprietary PureStem® progenitors, HyStem® hydrogels, culture media, and differentiation kits. BioTime is developing Renevia™ (a HyStem® product) as a biocompatible, implantable hyaluronan and collagen-based matrix for cell delivery in human clinical applications, and is planning to initiate a pivotal clinical trial around Renevia™, in 2014. In addition, BioTime has developed Hextend®, a blood plasma volume expander for use in surgery, emergency trauma treatment and other applications. Hextend® is manufactured and distributed in the U.S. by Hospira, Inc. and in South Korea by CJ HealthCare Corporation, under exclusive licensing agreements.

BioTime is also developing stem cell and other products for research, therapeutic, and diagnostic use through its subsidiaries:

• Asterias Biotherapeutics, Inc. is a new subsidiary which has acquired the stem cell assets of Geron Corporation, including patents and other intellectual property, biological materials, reagents and equipment for the development of new therapeutic products for regenerative medicine.
• BioTime Asia, Ltd., a Hong Kong company, may offer and sell products for research use for BioTime’s ESI BIO Division.
• Cell Cure Neurosciences Ltd. is an Israel-based biotechnology company focused on developing stem cell-based therapies for retinal and neurological disorders, including the development of retinal pigment epithelial cells for the treatment of macular degeneration, and treatments for multiple sclerosis.
• ESI BIO is the research and product marketing division of BioTime, providing stem cell researchers with products and technologies to enable them to translate their work into the clinic, including PureStem® progenitors and HyStem® hydrogels.
• LifeMap Sciences, Inc. markets, sells, and distributes GeneCards®, the leading human gene database, as part of an integrated database suite that also includes the LifeMap Discovery® database of embryonic development, stem cell research, and regenerative medicine, and MalaCards, the human disease database.
• LifeMap Solutions, Inc. is a subsidiary of LifeMap Sciences focused on developing mobile health (mHealth) products.
• OncoCyte Corporation is developing products and technologies to diagnose and treat cancer, including PanC-Dx™, with three clinical trials currently underway.
• OrthoCyte Corporation is developing therapies to treat orthopedic disorders, diseases and injuries.
• ReCyte Therapeutics, Inc. is developing therapies to treat a variety of cardiovascular and related ischemic disorders, as well as products for research using cell reprogramming technology.
