Data from BioTime’s OpRegen® Program to Be Presented at AAO 2018

BioTime, Inc. (NYSE American: BTX), a clinical-stage biotechnology company focused on degenerative diseases, today announced that its abstract "PI/IIa Study of Subretinally Transplanted Human Embryonic Stem Cell-Derived RPE Cells in Advanced Dry-Form AMD Patients,” has been accepted for an oral presentation at the upcoming American Academy of Ophthalmology (AAO) meeting taking place from October 27^th – October 30^th, 2018, in Chicago, Illinois.

"We are delighted that the AAO has accepted our abstract for an oral presentation at the upcoming meeting,” said Adi Mohanty, Co-Chief Executive Officer of BioTime. "We look forward to sharing more data from the ongoing OpRegen clinical trial where we have observed signals that may suggest structural improvement in the retina.”

The AAO is the world’s largest association of eye physicians and surgeons. It is comprised of more than 30,000 medical doctors, whose mission is to protect sight and empower lives by serving as an advocate for patients and the public, leading ophthalmic education, and advancing the profession of ophthalmology.

About OpRegen^®

OpRegen^®, which is being studied for the treatment of the dry form of 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^® will be administered in a single procedure. OpRegen^® was granted Fast Track designation from the 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 BioTime, Inc.

BioTime is a clinical-stage biotechnology company focused on degenerative diseases. Its clinical programs are based on two platform technologies: cell replacement and cell/drug delivery. With its cell replacement platform, BioTime is producing new cells and tissues with its proprietary pluripotent cell technologies. These cells and tissues are developed to replace those that are either rendered dysfunctional or lost due to degenerative diseases or injuries. BioTime’s cell/drug delivery programs are based upon its proprietary HyStem^® cell and drug delivery matrix technology. HyStem^® was designed, in part, to provide for the transfer, retention and/or engraftment of cellular replacement therapies. BioTime’s lead cell delivery clinical program is Renevia^®, which consists of HyStem^® combined with the patient's own adipose (fat) progenitor cells. Renevia^® met its primary endpoint in an EU pivotal clinical trial for the treatment of facial lipoatrophy in HIV patients in 2017. BioTime has submitted Renevia^® for CE Mark approval in the EU. There were no device related serious adverse events reported to date. BioTime’s lead cell replacement product candidate is OpRegen^®, a retinal pigment epithelium transplant therapy, which is in a Phase I/IIa multicenter clinical trial for the treatment of dry age-related macular degeneration, the leading cause of blindness in the developed world. There have been no unexpected serious adverse events reported to date. BioTime also has significant equity holdings in two publicly traded companies, Asterias Biotherapeutics, Inc. (NYSE American: AST) and OncoCyte Corporation (NYSE American: OCX), and a private company, AgeX Therapeutics, Inc.

BioTime common stock is traded on the NYSE American and TASE under the symbol BTX. For more information, please visit www.biotime.com or connect with the company on Twitter, LinkedIn, Facebook, YouTube, and Google+.
