Enrollment: 12
Study Start Date: March 2011
Study Completion Date: April 2015
Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: HuCNS-SC cells
Single dose intramedullary administration of HuCNS-SC cells
Biological: HuCNS-SC cells

Detailed Description:
Study subjects will receive immunosuppression for nine months following transplantation. All enrolled subjects will be followed for one year following transplantation and then will be enrolled in a separate long-term follow-up study for an additional four years.

Ages Eligible for Study:   18 Years to 60 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • T2-T11 thoracic spinal cord injury based on American Spinal Injury Association (ASIA) level determination by the principal investigator (PI)
  • T2-T11 thoracic spinal cord injury as assessed by magnetic resonance imaging (MRI) and/or computerized tomography (CT)
  • ASIA Impairment Scale (AIS) Grade A, B, or C
  • Minimum of six weeks post injury for the initiation of screening
  • Must have evidence of preserved conus function
  • Must be at stable stage of medical recovery after injury

Exclusion Criteria:

  • History of traumatic brain injury without recovery
  • Penetrating spinal cord injury
  • Evidence of spinal instability or persistent spinal stenosis and/or compression related to initial trauma
  • Previous organ, tissue or bone marrow transplantation
  • Previous participation in any gene transfer or cell transplant trial
  • Current or prior malignancy
