StemCells, Inc.'s Phase II Pathway Study for Cervical Spinal Cord Injury Approved by Health Canada

NEWARK, Calif., June 18, 2015 (GLOBE NEWSWIRE) -- StemCells, Inc. (Nasdaq:STEM), a world leader in the research and development of cell-based therapeutics for the treatment of central nervous system diseases and disorders, announced today that Health Canada has authorized the Company to expand its Phase II clinical trial for chronic cervical spinal cord injury into Canada. The Pathway Study™ is designed to assess the efficacy of the Company's proprietary HuCNS-SC® platform technology (purified human neural stem cells) for the treatment of cervical spinal cord injury with the primary efficacy outcome being the change in motor strength of the various muscle groups in the upper extremities innervated by the cervical spinal cord.



"This authorization should be very welcome news for spinal cord injury patients in Canada who will now have easier access to participate in the study," said Stephen Huhn, M.D., FACS, FAAP, Vice President, Clinical Research and CMO at StemCells, Inc. "This will allow expansion of the number of clinical trial sites and patients with spinal cord injury that the Company can include in our ongoing Pathway study. This will allow us to continue enrolling this breakthrough study in a very efficient fashion."

About the Pathway Cervical Spinal Cord Injury Clinical Trial

The Company's Phase II Pathway Study, titled "Study of Human Central Nervous System (CNS) Stem Cell Transplantation in Cervical Spinal Cord Injury," will evaluate the safety and efficacy of transplanting the Company's proprietary human neural stem cells (HuCNS-SC cells), into patients with traumatic injury in the cervical region of the spinal cord. Conducted as a randomized, controlled, single-blind study, the trial will measure efficacy by assessing motor function according to the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI). The primary efficacy outcome will focus on change in upper extremity strength. The trial will enroll approximately 52 subjects and follow the patients for 12 months post-transplant. The first cohort of six patients completed enrollment in April and was designed to establish the cell dose for onward testing in the second cohort of the study.

About HuCNS-SC Cells

StemCells, Inc. has demonstrated human safety data from completed and ongoing clinical studies in which its proprietary HuCNS-SC cells have been transplanted directly into all three components of the central nervous system: the brain, the spinal cord and the eye. StemCells, Inc. clinicians and scientists believe that HuCNS-SC cells may have broad therapeutic application for many diseases and disorders of the CNS. Because the transplanted HuCNS-SC cells have been shown to engraft and survive long-term in humans, there is the possibility of a durable clinical effect following a single transplantation. The HuCNS-SC platform technology is a highly purified composition of human neural stem cells (tissue-derived or "adult" stem cells). Manufactured under cGMP standards, the Company's HuCNS-SC cells are purified, expanded in culture, cryopreserved, and then stored as banks of cells, ready to be made into individual patient doses when needed.

About StemCells, Inc.

StemCells, Inc. is currently engaged in clinical development of its HuCNS-SC® platform technology (purified human neural stem cells) as a potential treatment for disorders of the central nervous system (CNS). Top line data from the Company's Phase I/II clinical trial in thoracic spinal cord injury (SCI) showed measurable gains involving multiple sensory modalities and segments, including the conversion of 2 of 7 patients enrolled in the study with complete injuries (AIS A) converting to incomplete injuries (AIS B), post-transplant. In addition to the completion of the Phase I/II thoracic SCI study and the ongoing Pathway Study, StemCells, Inc. has completed enrollment in its Phase I/II clinical trial in geographic atrophy of age-related macular degeneration (GA-AMD), the most severe form of dry AMD and the leading cause of blindness in the elderly. Based upon interim results for patients who had completed twelve months of follow-up, the Company reported reductions in the rate of progression in GA as compared to the untreated eye and the expected natural history of the disease. In a Phase I clinical trial in Pelizaeus-Merzbacher disease (PMD), a fatal myelination disorder in children, the Company showed preliminary evidence of progressive and durable donor-derived myelination by MRI.
