StemCells, Inc. (Nasdaq:STEM) announced today the initiation of a Phase I/II clinical trial of its proprietary HuCNS-SC® human neural stem cells in chronic spinal cord injury. This trial is now open for enrollment, and will accrue patients with both complete and incomplete degrees of paralysis who are three to 12 months post-injury. The trial is being conducted in Switzerland at the Balgrist University Hospital, University of Zurich, a world leading medical center for spinal cord injury and rehabilitation, and is being led by Armin Curt, MD, Professor and Chairman, Spinal Cord Injury Center at the University of Zurich, and Medical Director of the Paraplegic Center at the Balgrist University Hospital.
Dr. Curt stated, "The launch of this trial is truly a landmark event for the field of spinal cord injury research. For patients facing a lifetime of paralysis, the prospect that neural stem cell transplantation may one day help restore some degree of function offers new hope. What is particularly exciting to me is the innovative design of this trial. Within the setting of one trial, we will progress from the most severely injured to less severely injured. In addition to our primary focus on assessing safety, the design of the trial will afford a very real near-term opportunity to observe possible benefits to the patient, which may include improved sensation, motor function, bowel or bladder function. I am extremely pleased to be involved in a study that is breaking barriers in the search for a treatment that could lead to improved quality of life for injured patients."
Stephen Huhn, MD, FACS, FAAP, Vice President and Head of the CNS Program at StemCells, Inc., added, "Dr. Curt is an internationally renowned expert in spinal cord injury, and we look forward to working with him and his team of experienced investigators at Balgrist. Our HuCNS-SC cells have shown significant promise in preclinical studies for restoring lost motor function, and we are excited to take this important first step toward our goal of developing a neural stem cell therapy that could offer similar benefits for patients living with paralysis. We plan to enroll the first cohort of patients with complete injury this year, and will then transition to patients with incomplete injuries early next year."
About the Trial
The trial is designed to assess both safety and preliminary efficacy. The trial will enroll 12 patients with thoracic (chest-level) spinal cord injury who have a neurological injury level of T2-T11, and will include both complete and incomplete injuries as classified by the American Spinal Injury Association (ASIA) Impairment Scale. The first cohort will be patients classified as ASIA A, or patients who have what is considered to be a "complete" injury, or no movement or feeling below the level of the injury. The second cohort will progress to patients classified as ASIA B, or patients with some degree of feeling below the injury. The third cohort will consist of patients classified as ASIA C, or patients with some degree of movement below the injury. In addition to assessing safety, the trial will measure defined clinical endpoints, such as changes in sensation, motor, and bowel/bladder function. All patients will receive HuCNS-SC cells through direct transplantation into the spinal cord, and will be temporarily immunosuppressed. Following transplantation, the patients will be evaluated regularly over a 12-month period in order to monitor and evaluate the safety and tolerability of the HuCNS-SC cells, the surgery and the immunosuppression, and to measure any recovery of neurological function below the injury site. As the Company intends to follow the effects of this therapy long-term, a separate four-year observational study will be initiated at the conclusion of this trial.
