A Study of Modified Stem Cells in Stable Ischemic Stroke

Not Recruiting

Trial ID: NCT01287936


The primary purpose of the clinical study is to determine the safety of a modified stem cell SB623 when administered to chronic, stable ischemic stroke patients. A second purpose is to determine whether SB623 might improve stroke symptoms. Chronic, stable ischemic stroke patients must be between 6 and 60 months after their stroke, and with only this one prior stroke, and with no further improvement from physical therapy.
