Brief Summary:
Stroke is a major cause of adult disability. Currently approved reperfusion therapies are provided to only a small percentage of patients in the U.S. New therapies are needed that improve outcome and that can be accessed by a majority of patients. Animal studies suggest that bone marrow-derived mesenchymal stem cells, administered intravenously days after a stroke, safely improve long-term behavioral outcome. A large human experience suggests the safety of allogeneic bone marrow-derived mesenchymal stem cells. The current study aims to assess the safety of this therapy in patients with recent ischemic stroke.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • 1. Ischemic stroke in the middle cerebral artery territory, with onset 24-72 hours prior to the time that the therapy transfusion is initiated, radiologically confirmed, and with either diameter >15 mm or volume > 4cc.
  • 2. The index stroke has clinical deficits that are moderate-severe (NIHSS score 7-20), did not require hemicraniectomy or invasive intracranial pressure monitoring, and was not associated with a concomitant STelevation myocardial infarction.
  • 3. Age 18-80 years, inclusive
  • 4. Reasonable likelihood of receiving standard post-stroke medical care, as well as standard physical, occupational, and speech therapy.

Exclusion Criteria:

  • 1. No substantial pre-stroke disability (pre-stroke modified Rankin Scale score 0-2).
  • 2. Females of child-bearing potential will be excluded unless (1) a negative urine pregnancy test is obtained and (2) the patient has been effectively using contraceptive method with known failure rate <1 % for at least 90 days.
  • 3. Lactating mothers
  • 4. If thrombolytic therapy has been administered, at least 24 hours have passed between completing thrombolytic dosing and initiating the current study's transfusion.
  • 5. Known allergy to penicillin or to fetal bovine serum
  • 6. Active co-existent major neurological or psychiatric disease that could significantly interfere with patient compliance or study assessments, including drug or alcohol abuse.
  • 7. Any diagnosis that makes survival to 1-year post-stroke unlikely.
  • 8. Participation in any other experimental therapeutic clinical trial concurrently or in the prior three months.
  • 9. Contraindication to undergoing MRI scanning.
