NCT03505034

Brief Summary

This study aim to evaluate the safety and efficacy of intrathecal transplantation of allogeneic umbilical cord derived mesenchymal stem cells (UC-MSC) for treatment of different phrases of spinal cord injury. Here, the history of spinal cord injury is divided into three periods, Sub-acute SCI, Early stage of chronic SCI, and Late stage of chronic SCI, which is 2W-2M, 2M-12M, and more than 12M after injury, respectively. The purpose is to investigate whether the patients with spinal cord injury benefit from UC-MSC transplantation, and then find out the best time for SCI treatment. In this part of the study, the investigators will treat patients with late stage of chronic spinal cord injury with UC-MSC transplantation or placebo.

Outcome Measures

Primary Outcomes (1)

  • Changes in American Spinal Injury Association (ASIA) Score Scale

    Changes in motor and sensory scores assessed by the ASIA score scale (total score range from 0 to 324, higher values represent a better outcome)

    Baseline, 1 month, 3 months, 6 months and 12 months post-treatment

Secondary Outcomes (3)

  • Changes in International Association of Neural Restoration Spinal Cord Injury Functional Rating Scale (IANR-SCIRFS)

    Baseline, 1 month, 3 months, 6 months and 12 months post-treatment

  • Changes in electromyogram test

    Baseline, 6 months and 12 months post-treatment

  • Changes in residual urine

    Baseline, 6 months and 12 months post-treatment
