Brief Summary:
This is a double-blind, randomized, placebo-controlled, multicenter clinical trial in which 18 patients affected with chronic traumatic incomplete cervical spinal cord injury will be randomized to either the active treatment (2 doses of intrathecal WJ-MSC 3 months apart) or to placebo (2 intrathecal infusions, 3 months apart). Thereafter, patients will be followed-up for 12 months for safety and efficacy assessment.

Condition or disease Intervention/treatment Phase
Spinal Cord Injury Cervical Drug: WJ-MSC (XCEL-UMC-BETA) Drug: Placebo Phase 1 Phase 2

Detailed Description:
Double-blind, randomized, placebo-controlled, multicenter clinical trial that will include 18 patients affected with chronic traumatic incomplete cervical spinal cord injury who will be randomized 2:1, stratified by center, to one of the 2 treatment arms of the study: WJ-MSC / WJ-MSC (at a dose of 1E6 ± 30% live cells / Kg of weight) or Placebo / placebo. Medication will be administered intrathecally at day 1 and at 3 months. The main objective of the trial is to assess safety at 12-month follow-up. Secondary objectives include the evaluation of efficacy through clinical response, electrophysiological changes, questionnaires of functionality and quality of life, as well as the presence of anti-HLA antibodies and donor cellularity in the cerebrospinal fluid.

Primary Outcome Measures :
  1. Incidence of adverse events [ Time Frame: At 12 month follow-up ]
    Adverse events


Secondary Outcome Measures :
  1. American Spinal Injury Association (ASIA) impairment scale [ Time Frame: At 1, 3, 4, 6 and 12 month follow-up ]
    Changes in ASIA score with respect to baseline value as detailed at https://asia-spinalinjury.org/international-standards-neurological-classification-sci-isncsci-worksheet/

  2. Motor evoked potentials [ Time Frame: At 6 and 12 month follow-up ]
    Changes in motor evoked potentials score with respect to baseline value. Higher scores mean a better outcome

  3. Somatosensory evoked potentials [ Time Frame: At 6 and 12 month follow-up ]
    Changes in somatosensory evoked potentials score with respect to baseline value. Higher scores mean a better outcome

  4. Electrical pain threshold perception [ Time Frame: At 6 and 12 month follow-up ]
    Changes in electrical pain threshold perception score with respect to baseline. Lower scores mean a better outcome

  5. Handgrip Strength [ Time Frame: At 6 and 12 month follow-up ]
    Will be assessed using a dynamometer. Changes in the score with respect to baseline values. Higher scores mean a better outcome

  6. Walking index for spinal cord injury (WISCI II) [ Time Frame: At 6 and 12 month follow-up ]
    Changes in the walk test WISCIII score with respect to baseline value. The score ranges from 0 (most severe impairment) to 20 (least severe impairment)

  7. Numerical scale for neuropathic pain assessment [ Time Frame: At 6 and 12 month follow-up ]
    Changes in the numerical scale for neuropathic pain score with respect to baseline value. Score ranges from 0 (no pain) to 10 (unbearable pain)

  8. Modified Ashworth scale for spasticity [ Time Frame: At 6 and 12 month follow-up ]
    Changes in the modified Ashworth scale score with respect to baseline value. It is a 5 point numerical scale that graded spasticity from 0 to 4, with 0 being no resistance and 4 being a limb rigid in flexion or extension, and includes a 1+ value.

  9. Spinal Cord Independence Measure III (SCIM III) [ Time Frame: At 6 and 12 month follow-up ]
    Changes in the SCIM III scale score with respect to baseline value. Score ranges from 0 to 20 with higher scores meaning better outcome.

  10. World Health Organization Quality of life questionnaire (WHOQOL-BREF) [ Time Frame: At 6 and 12 month follow-up ]
    Changes in the WHOQOL-BREF score with respect to baseline value. It contains contains 26 questions each punctuated from 1 to 5 and assesses the individual's overall perception of quality of life (1 to 5), overall perception of their health (1 to 5) and 4 domains of physical health, psychological, social relationships, environment (0-100 each domain). higher scores denote higher quality of life.

  11. Psychological general well-being index (PGWBI) [ Time Frame: At 12 month follow-up ]
    Changes in the PGWBI score with respect to baseline value. Score ranges from 0 to 132, with higher scores meaning a better outcome.

  12. Hospital Anxiety and Depression Scale (HADS) [ Time Frame: At 12 month follow-up ]
    Changes in the HADS score with respect to baseline value. This is a 14-item self-administered questionnaire containing 2 subscales (one for anxiety and one for depression), with a score range of each subscale from 0-21. Higher score indicates higher anxiety and depression.

  13. Community Integration Questionaire (CIQ-IG) [ Time Frame: At 12 month follow-up ]
    Changes in the CIQ-IG score with respect to baseline value. Score ranges from 0 to 25, with higher scores meaning a better outcome.

  14. AntiHLA antibodies in cerebrospinal fluid (CSF) [ Time Frame: At 7 days and at 1 month follow-up after each infusion ]
    Presence or absence of antiHLA antibodies in the CSF after two WJ-MSC infusions

  15. Detection of donor cells in CSF [ Time Frame: At 7 days after each infusion ]
