FREMONT, Calif., Sept. 7, 2016 /PRNewswire/ -- Asterias Biotherapeutics, Inc. (NYSE MKT: AST), today announced that Edward Wirth, MD, PhD, Chief Medical Officer, will present interim efficacy data from the 10 million cell cohort in the company's ongoing AST-OPC1 SCiSTAR Phase 1/2a clinical study in complete cervical spinal cord injury patients on Wednesday, September 14, 2016. The presentation will take place during the 55th Annual Scientific Meeting of the International Spinal Cord Society (ISCoS), which is being held in Vienna, Austria, on September 14-16, 2016.
The SCiStar study is funded in part by a $14.3 million grant from the California Institute for Regenerative Medicine (CIRM).
Data evaluating the efficacy results six months after implantation of 10 million AST-OPC1 cells in complete cervical spinal cord injury patients will be available in January 2017 and will focus on improvement in physical functioning of the upper extremities (fingers, hands and arms) of each treated patient utilizing scoring on the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI scale). The interim efficacy data to be presented on Wednesday, September 14, 2016 will discuss the efficacy results observed in these patients to date.
Asterias will host a conference call and webcast on September 14, 2016 at 4:30 p.m. Eastern / 1:30 p.m. Pacific to discuss Dr. Wirth's presentation. For both "listen-only" participants and those participants who wish to take part in the question-and-answer portion of the call, the dial-in number in the U.S./Canada is 888-224-1005. For international participants outside the U.S./Canada, the dial-in number is 913-312-0863. For all callers, refer to Conference ID 7322708.

About the SCiStar Trial
The SCiStar trial is 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. 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).
Asterias previously announced that it had been granted FDA clearance to expand patient enrollment in the Phase 1/2a clinical trial from 13 patients to up to 35 patients, based on the continued favorable safety profile observed in the ongoing clinical study. The Company believes that this change will increase the statistical confidence of the safety and efficacy readouts, reduce the risks of the AST-OPC1 program and position the product for potential accelerated regulatory approvals. 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.
More than 17,000 people sustain a spinal cord injury each year, but there are no FDA-approved therapeutics or devices that could potentially restore some function in individuals who have recently sustained a spinal cord injury.
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 the administration of the cells, with AST-OPC1 itself, or the immunosuppressive regimen. 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 approval from FDA to progress testing of AST-OPC1 to patients with complete cervical spine injuries, which represents the first targeted population for registration trials.
About Asterias Biotherapeutics
Asterias Biotherapeutics, Inc. is a leading biotechnology company in the emerging field of regenerative medicine. The company's proprietary cell therapy programs are based on its immunotherapy and pluripotent stem cell 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 oncology and neurology. 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 being evaluated by Asterias for further development after demonstrating promise in a Phase 2 study in Acute Myeloid Leukemia (AML) and completing a successful end-of-Phase 2 meeting with the FDA. AST-VAC2 (antigen-presenting allogeneic dendritic cells) represents a second generation, allogeneic immunotherapy. The company's research partner, Cancer Research UK, plans to begin a Phase 1/2 clinical trial of AST-VAC2 in non-small cell lung cancer in 2017.
