Opens Enrollment to Patients in US and Canada
NEWARK, Calif., Dec. 15, 2011 (GLOBE NEWSWIRE) -- StemCells, Inc. (Nasdaq:STEM) announced today that the first cohort of the Company's Phase I/II clinical trial in chronic spinal cord injury have been successfully transplanted with the Company's proprietary HuCNS-SC® neural stem cells. This landmark clinical trial has a unique design, in which patients with progressively decreasing severity of injury will be treated in three sequential cohorts. The first cohort of patients all have spinal cord injury classified as AIS A, the most severe level identified by the American Spinal Injury Association Impairment Scale (AIS).
"We are extremely pleased with our progress in this innovative trial," said Stephen Huhn MD, FACS, FAAP, Vice President and Head of the CNS Program at StemCells, Inc. "Having completed dosing of the AIS A cohort, screening for AIS B patients, who have a less severe, incomplete type of spinal cord injury, can now begin. Of course, our first priority is to assess safety in each patient, but we will also be evaluating trial patients for changes in sensation, motor and bowel/bladder function."
"I am also pleased to announce," added Martin McGlynn, President and CEO, "that, in consultation with the clinical team at Balgrist Hospital, the Company has decided to open enrollment for the remainder of the trial to patients living in the United States and Canada. We have received a large number of inquiries from patients in both countries, and hopefully this decision will come as good news to the spinal cord injury community, who were greatly disappointed by Geron's recent decision to discontinue its spinal cord injury trial. We remain optimistic about the prospect of being able to demonstrate safety and clinical utility of our cells in this devastating condition, and are committed to funding our spinal cord injury program until such time as we can come up with a definitive outcome."
About the Clinical Trial
The Phase I/II clinical trial of StemCells, Inc.'s HuCNS-SC purified human adult neural stem cells is designed to assess both safety and preliminary efficacy. Twelve patients with thoracic (chest-level) neurological injuries at the T2-T11 level are planned for enrollment. The first three patients all have injuries classified as AIS A, in which there is no apparent neurological function below the injury level. The second and third cohorts will be patients classified as AIS B and AIS C, those with less severe injury, in which there is some preservation of sensory or motor function. In addition to assessing safety, the trial will assess preliminary efficacy based on defined clinical endpoints, such as changes in sensation, motor and bowel/bladder function. Prior to dosing the next cohort, data from previous cohorts will be reviewed by an independent Data Safety Monitoring Committee.
All patients will receive HuCNS-SC cells through direct transplantation into the spinal cord and will be temporarily immunosuppressed. Patients will be evaluated regularly in the post-transplant period in order to monitor and assess the safety of the HuCNS-SC cells, the surgery and the immunosuppression, as well as to measure any recovery of neurological function below the injury site. The Company intends to follow the effects of this therapy long-term, and a separate four-year observational study will be initiated at the conclusion of this trial.
The trial is being conducted at Balgrist University Hospital, University of Zurich, a world leading medical center for spinal cord injury and rehabilitation.

About Chronic Spinal Cord Injury
According to a study reported by the Christopher and Dana Reeve Foundation, nearly 1.3 million people in the United States are estimated to be living with chronic spinal cord injury. The chronic phase of spinal cord injury is considered to begin when inflammation has stabilized and recovery has reached a plateau, which is typically several months following injury. Currently, there are no effective treatment options for patients with chronic spinal cord injury, and treatment approaches have generally targeted the acute and sub-acute time points, which are within hours or days of injury. Given the unmet need in chronic spinal cord injury, restoring some degree of function for patients at time points beyond the acute phase could have a transformative impact on the field. StemCells hopes to address a broad population of spinal cord-injured patients by opening the window of opportunity for therapeutic intervention well after the acute injury and targeting a wide range of injury levels and degrees of impairment.
