The trial is designed to enroll up to 118 patients who have suffered an ischemic stroke with chronic residual motor disorder with Neuralstem's NSI-566 cell line, 4-24 months post-stroke. The stem cell treatment involves a one-time treatment of intracerebral injections of Neuralstem's neural stem cells into the stroke area using well-accepted stereotactic injection procedures. The trial will be conducted in 2 parts. The first part of the study, Phase I, will be open-label and enroll up to 18 patients who will be assigned to 3 cohorts. Each of these will receive ascending doses of NSI-566 to define the maximal safe dose. The maximal safe dose defined in the first phase will be used to evaluate efficacy in the second part of the study, a Phase II/Proof-of-Concept study. This Phase will be a multi-site, randomized, controlled, single-blind study and enroll up to 100 randomized subjects. 50% of the subjects will receive a one-time treatment with the cells and physical therapy and the other 50% will receive only the physical therapy with no surgery. Outcome measures during the follow-up period in Phase II will be conducted in single-blinded manner. The combined study, including patient monitoring and data collection, is expected to take approximately two years.About Neuralstem China Founded in 2010, Neuralstem China (Suzhou Sun-Now Biopharmaceutical Co. Ltd. is a wholly-owned subsidiary of Neuralstem, Inc., headquartered in Suzhou, roughly one hundred miles west of Shanghai. Neuralstem China has constructed a clinical-grade manufacturing facility), and holds the license required by the Chinese government for conducting business in China. Neuralstem's mission in China is to bring its world-leading neural stem cell technology to China to address the unmet medical needs of tens of millions of patients suffering from diseases of, and injuries to, the central nervous system (CNS). Neuralstem China intends to move its best-in-class stem cell therapeutics through Chinese clinical and regulatory pathways, harmonizing a Western style of discipline and care with existing Chinese traditions and commercialization culture. China has many different regulatory paths to commercialization. Neuralstem's product advancement strategy is to pursue each path simultaneously. About Neuralstem Neuralstem's patented technology enables the ability to produce neural stem cells of the human brain and spinal cord in commercial quantities, and the ability to control the differentiation of these cells constitutively into mature, physiologically relevant human neurons and glia. Neuralstem has recently completed an FDA-approved Phase I safety clinical trial for amyotrophic lateral sclerosis (ALS), often referred to as Lou Gehrig's disease, and has been awarded orphan status designation by the FDA. In addition to ALS, the company is also targeting major central nervous system conditions with its NSI-566 cell therapy platform, including spinal cord injury, ischemic spastic paraplegia and chronic stroke. The company has submitted an IND (Investigational New Drug) application to the FDA for a Phase I safety trial in spinal cord injury.
