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.

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 1:1, 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 a 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.

Interventions

DRUGWJ-MSC (XCEL-UMC-BETA)

Administration of 2 Intrathecal infusions of WJ-MSC at day 1 and at 3 months

DRUGPlacebo

Administration of 2 Intrathecal infusions of placebo at day 1 and at 3 months

MeasureTime frameDescription
Incidence of adverse eventsAt 12 month follow-upAdverse events

Secondary

MeasureTime frameDescription
Motor evoked potentialsAt 6 and 12 month follow-upChanges in motor evoked potentials score with respect to baseline value. Higher scores mean a better outcome
Somatosensory evoked potentialsAt 6 and 12 month follow-upChanges in somatosensory evoked potentials score with respect to baseline value. Higher scores mean a better outcome
Electrical pain threshold perceptionAt 6 and 12 month follow-upChanges in electrical pain threshold perception score with respect to baseline. Lower scores mean a better outcome
Handgrip StrengthAt 6 and 12 month follow-upWill be assessed using a dynamometer. Changes in the score with respect to baseline values. Higher scores mean a better outcome
Walking index for spinal cord injury (WISCI II)At 6 and 12 month follow-upChanges in the walk test WISCIII score with respect to baseline value. The score ranges from 0 (most severe impairment) to 20 (least severe impairment)
Numerical scale for neuropathic pain assessmentAt 6 and 12 month follow-upChanges in the numerical scale for neuropathic pain score with respect to baseline value. Score ranges from 0 (no pain) to 10 (unbearable pain)
Modified Ashworth scale for spasticityAt 6 and 12 month follow-upChanges 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.
American Spinal Injury Association (ASIA) impairment scaleAt 1, 3, 4, 6 and 12 month follow-upChanges in ASIA score with respect to baseline value as detailed at https://asia-spinalinjury.org/international-standards-neurological-classification-sci-isncsci-worksheet/
World Health Organization Quality of life questionnaire (WHOQOL-BREF)At 6 and 12 month follow-upChanges 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.
Psychological general well-being index (PGWBI)At 12 month follow-upChanges in the PGWBI score with respect to baseline value. Score ranges from 0 to 132, with higher scores meaning a better outcome.
Hospital Anxiety and Depression Scale (HADS)At 12 month follow-upChanges 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.
Community Integration Questionaire (CIQ-IG)At 12 month follow-upChanges in the CIQ-IG score with respect to baseline value. Score ranges from 0 to 25, with higher scores meaning a better outcome.
AntiHLA antibodies in cerebrospinal fluid (CSF)At 7 days and at 1 month follow-up after each infusionPresence or absence of antiHLA antibodies in the CSF after two WJ-MSC infusions
Detection of donor cells in CSFAt 7 days after each infusionShort tandem repeat (STR) analysis to detect permanence of donor cellularity (WJ-MsC) in the CSF
Spinal Cord Independence Measure III (SCIM III)At 6 and 12 month follow-upChanges in the SCIM III scale score with respect to baseline value. Score ranges from 0 to 20 with higher scores meaning better outcome.
