Primary Outcome Measures:
  • American Spinal Injury Association (ASIA) Impairment Scale Improvement [ Time Frame: Four years ]
    Evidence of improvement in ASIA impairment scale as confirmed by neurological examination

Enrollment: 12
Study Start Date: November 2012
Study Completion Date: May 2016
Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
No treatment
Other: Observation

Detailed Description:

The investigation is a multi-year observational study following the completion of the open-label, single dose Phase I/II study involving transplantation of allogeneic HuCNS-SC cells into 12 subjects with thoracic spinal cord injury.

Subjects will be monitored at routine intervals for safety and preliminary efficacy for four years. The LTFU study will commence following the one year post-transplantation termination visit of the Phase I/II investigation.
