FREMONT, Calif., Aug. 23, 2017 (GLOBE NEWSWIRE) -- Asterias Biotherapeutics, Inc. (NYSE MKT:AST), a biotechnology company pioneering the field of regenerative medicine, today announced that Washington University School of Medicine in St. Louis, MO, has been added as a clinical site in the company’s ongoing SCiStar Phase 1/2a clinical trial of AST-OPC1, a stem-cell derived investigational therapy, in patients with severe cervical spinal cord injury (SCI). There are now nine clinical sites enrolling patients in the study.
Washington University and its partner Barnes-Jewish Hospital have one of the largest clinical spine care practices in the United States. W. Zachary Ray, MD, Associate Professor of Neurological and Orthopedic Surgery at Washington University School of Medicine, will be the site’s principal investigator. Patients enrolled in the trial will receive the AST-OPC1 treatment during surgery at Barnes-Jewish.
“Given the study’s encouraging early results, we look forward to evaluating whether AST-OPC1 can advance treatment options for patients with severe cervical spinal cord injuries. This investigational therapy is an important contribution to our comprehensive program to treat spinal cord injuries here at Washington University and Barnes-Jewish,” said Dr. Ray.
Barnes-Jewish Hospital’s Trauma Center was the first in Missouri to receive the American College of Surgeons (ACS) Level I verification, which is the highest national recognition possible from ACS.
“Washington University School of Medicine is a great addition to our current AST-OPC1 SCiStar study. We hope Washington University School of Medicine will also participate in a future randomized controlled trial of AST-OPC1,” stated Dr. Edward Wirth III, Chief Medical Officer of Asterias Biotherapeutics.
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 subacute motor complete (AIS-A or AIS-B) cervical (C-4 to C-7) 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 have retained some minimal sensory function below their injury site. AST-OPC1 is being administered 21 to 42 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 nine centers in the U.S. 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, Santa Clara Valley Medical Center in San Jose jointly with Stanford University, Thomas Jefferson University Hospital in partnership with Magee Rehabilitation Hospital in Philadelphia, UC San Diego Health in San Diego, California, and Washington University School of Medicine in partnership with Barnes-Jewish Hospital in St. Louis, MO.
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.
AST-OPC1, an oligodendrocyte progenitor population derived from human embryonic stem cells originally isolated in 1998, 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. Based on the results of this study, Asterias received clearance from FDA to progress testing of AST-OPC1 to patients with cervical spine injuries in the current SCiStar study, which represents the first targeted population for registration trials. Asterias has completed enrollment in the first four cohorts of this study. Results to date have continued to support the safety of AST-OPC1. Additionally, Asterias has recently reported results suggesting reduced cavitation and improved motor function in patients administered AST-OPC1 in the SCiStar trial.
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.
