Outcome Measures

Primary Outcomes (3)

  • Adverse events

    All adverse events (AEs) are registered within follow-up period. All registered AEs are classified using CTCAE classification and relation to the performed therapy.

    Continuously for 12 months post-SCI

  • Motor function

    Evaluation of motor function dynamics in upper (UEMS), lower (LEMS) and all (GEMS) limbs

    Change from Baseline 12 months post-SCI

  • Neurological deficit

    Evaluation of general neurological deficit dynamics using ASIA scale

    Change from Baseline 12 months post-SCI

Secondary Outcomes (9)

  • Sensory function

    Change from Baseline 12 months post-SCI

  • Neuropathic pain syndrome

    12 months post-SCI

  • Independent verticalization and motion ability

    Change from Baseline 12 months post-SCI

  • Limb muscle spasticity

    Change from Baseline 12 months post-SCI

  • Psychological status

    Change from Baseline 12 months post-SCI

  • +4 more secondary outcomes

Study Arms (2)

Cell Therapy

EXPERIMENTAL

Patients having acute severe contusion spinal cord injury (cervical, thoracic or upper-lumbar) and ASIA A/B neurological deficit, within 7 days post-SCI, after primary decompressive and stabilizing surgery. All participants meet inclusion and exclusion criteria. All participants obtain 4 infusions of allogenic non-related group- and rhesus-compatible mononuclear cord blood cells samples (500 +/- 50 x 10\*6 cells each) with a 1-week interval. All participants are followed up for 12 months post-SCI.

Biological: Multiple systemic (i.v.) administration of allogenic non-related group- and rhesus-compatible mononuclear cord blood cells

Vehicle

PLACEBO COMPARATOR

Patients having acute severe contusion spinal cord injury (cervical, thoracic or upper-lumbar) and ASIA A/B neurological deficit, within 7 days post-SCI, after primary decompressive and stabilizing surgery. All participants meet inclusion and exclusion criteria. All participants obtain 4 infusions of vehicle (sterile saline) with a 1-week interval. All participants are followed up for 12 months post-SCI.

Other: Control vehicle (sterile saline)

Interventions

Each HUCBCs sample contain 500 +/- 50 x 10\*6 allogenic non-related group- and rhesus-compatible mononuclear cord blood cells

Cell Therapy

Sterile saline infusion in control patients

Vehicle

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Both males and females, 18 to 75 years old
  • Contusion spinal cord injury (SCI) at cervical, thoracic or upper lumbar (cone level) levels
  • admission by 7 days post-SCI
  • spinal cord contusion confirmed using MRI (T1- and T2-weighted images, STIR)
  • ASIA A/B neurological deficit
  • primary decompressive and stabilizing surgery performed within 5 days post-SCI and prior to the first cell sample infused
  • patient is ready to participate and fulfill the requirements of the study protocol
  • informed consent signed by the patient or his legal representative

You may not qualify if:

  • motor function preserved in lower limbs at admission (LEMS \> 0 points) corresponding to ASIA C, D or E deficit level
  • any spinal cord injury different from contusion (tear, defibering, concussion, SCIWORA, SCIWONA) confirmed using MRI
  • severe combined trauma (ISS \> 35 points)
  • inability to perform primary decompressive and stabilizing surgery within 5 days post-SCI and prior to the first cell sample infused
  • acute myocardial infarction
  • blood glucose level \< 3.5 Mmol/L or \>21 Mmol/L or ineffective antidiabetic therapy for 24 hours
  • acute or deterioration of chronic diseases of central nervous system (CNS) (e.g. stroke, non-traumatic subarachnoid hemorrhages and others at the discretion of investigator)
  • objective need for artificial ling ventilation (ALV) at admission or prior to the stage I surgery
  • acute kidney failure or deterioration of chronic kidney failure (creatinin level \> 250 mumol/L or carbamide level \> 25 Mmol/L)
  • liver failure (general bilirubin level \> 25 mumol/L, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels \> 4 times exceeding upper reference limit)
  • other significant disorders of vital functions
  • acute of deterioration of chronic diseases of internal organs preventing from cell samples infusion
  • autoimmune diseases (active or anamnestic) preventing from cell samples infusion
  • allergic reactions of any type for any component of HUCBC samples
  • pregnancy or lactation
  • +9 more criteria

Masking Details
Participants in the experimental group will obtain 4 systemic (i.v.) infusions of allogenic group- and rhesus-compatible non-related mononuclear cord blood cell samples (500 +/- 50 x 10'6 cells each). Participants in the control group will obtain the similar volume of vehicle (sterile saline). Participant's devision will be performed in a randomized manner. Randomization will be performed using standard randomization computer table. All participants will be blinded concerning the therapy mode.
