Asterias Biotherapeutics to Present New 9-Month Efficacy Data from AST-OPC1 SCiStar Study at the International Society for Stem Cell Research (ISSCR) 2017 Annual Meeting

FREMONT, Calif., June 8, 2017 /PRNewswire/ -- Asterias Biotherapeutics, Inc. (NYSE MKT: AST), a biotechnology company pioneering the field of regenerative medicine, today announced that it will present new 9-month efficacy and safety data on those AIS-A patients treated with 10 million cells of AST-OPC1 in the company's ongoing SCiStar Phase 1/2a study in complete cervical spinal cord injury. This update will take place during a pre-meeting workshop and a poster session at the International Society for Stem Cell Research (ISSCR) 2017 Annual Meeting held in Boston, MA during June 14-17, 2017.

Jane S. Lebkowski, Ph.D., the company's President of R&D and Chief Scientific Officer, will provide an overview of the study, including the 9-month efficacy and safety data on the AIS-A 10 million cell cohort. The presentation slides will be available on the company's website following the presentation at http://asteriasbiotherapeutics.com/inv_events_presentations.php.

About the SCiStar Trial

The SCiStar trial is an open-label, single-arm trial testing three sequential escalating doses of AST-OPC1 administered at up to 20 million AST-OPC1 cells in as many as 35 patients with sub-acute, C-5 to C-7, motor complete (AIS-A or AIS-B) cervical SCI. These individuals have essentially lost all movement below their injury site and experience severe paralysis of the upper and lower limbs. AIS-A patients have lost all motor and sensory function below their injury site, while AIS-B patients have lost all motor function but may retain some minimal sensory function below their injury site. AST-OPC1 is being administered 14 to 30 days post-injury. Patients will be followed by neurological exams and imaging procedures to assess the safety and activity of the product.

The study is being conducted at six centers in the U.S. and the company plans to increase this to up to 12 sites to accommodate the expanded patient enrollment. Clinical sites involved in the study include the Medical College of Wisconsin in Milwaukee, Shepherd Medical Center in Atlanta, University of Southern California (USC) jointly with Rancho Los Amigos National Rehabilitation Center in Los Angeles, Indiana University, Rush University Medical Center in Chicago and Santa Clara Valley Medical Center in San Jose jointly with Stanford University.

Asterias has received a Strategic Partnerships Award grant from the California Institute for Regenerative Medicine, which provides $14.3 million of non-dilutive funding for the Phase 1/2a clinical trial and other product development activities for AST-OPC1.

Additional information on the Phase 1/2a trial, including trial sites, can be found at www.clinicaltrials.gov, using Identifier NCT02302157, and at the SCiStar Study Website (www.SCiStar-study.com).

About AST-OPC1

AST-OPC1, an oligodendrocyte progenitor population derived from human embryonic stem cells, has been shown in animals and in vitro to have three potentially reparative functions that address the complex pathologies observed at the injury site of a spinal cord injury. These activities of AST-OPC1 include production of neurotrophic factors, stimulation of vascularization, and induction of remyelination of denuded axons, all of which are critical for survival, regrowth and conduction of nerve impulses through axons at the injury site. In preclinical animal testing, AST-OPC1 administration led to remyelination of axons, improved hindlimb and forelimb locomotor function, dramatic reductions in injury-related cavitation and significant preservation of myelinated axons traversing the injury site.

In a previous Phase 1 clinical trial, five patients with neurologically complete, thoracic spinal cord injury were administered two million AST-OPC1 cells at the spinal cord injury site 7-14 days post-injury. They also received low levels of immunosuppression for the next 60 days. Delivery of AST-OPC1 was successful in all five subjects with no serious adverse events associated with AST-OPC1. No evidence of rejection of AST-OPC1 was observed in detailed immune response monitoring of all patients. In four of the five patients, serial MRI scans indicated that reduced spinal cord cavitation may have occurred. Based on the results of this study, Asterias received clearance from FDA to progress testing of AST-OPC1 to patients with cervical spine injuries, which represents the first targeted population for registration trials.

About Asterias Biotherapeutics

Asterias Biotherapeutics, Inc. is a biotechnology company pioneering the field of regenerative medicine. The company's proprietary cell therapy programs are based on its pluripotent stem cell and immunotherapy platform technologies. Asterias is presently focused on advancing three clinical-stage programs which have the potential to address areas of very high unmet medical need in the fields of neurology and oncology. AST-OPC1 (oligodendrocyte progenitor cells) is currently in a Phase 1/2a dose escalation clinical trial in spinal cord injury. AST-VAC1 (antigen-presenting autologous dendritic cells) is undergoing continuing development by Asterias based on promising efficacy and safety data from a Phase 2 study in Acute Myeloid Leukemia (AML), with current efforts focused on streamlining and modernizing the manufacturing process. AST-VAC2 (antigen-presenting allogeneic dendritic cells) represents a second generation, allogeneic cancer immunotherapy. The company's research partner, Cancer Research UK, plans to begin a Phase 1/2a clinical trial of AST-VAC2 in non-small cell lung cancer in 2017.
