Brief Summary:
The purpose of this study is to determine the safety of using oral Glyburide in patients with acute traumatic cervical spinal cord injuries (SCI).

Condition or disease Intervention/treatment Phase
Acute Spinal Cord Injury Drug: Glyburide Phase 1 Phase 2

Detailed Description:
This study will include patients between 18 and 80 years who have experienced acute traumatic cervical spinal cord injury (specifically ASIA A, B or C). Patients will then begin an oral drug regimen of Glyburide, which must be started within 8 hours of injury and continued for 72 hours at a daily dose of 3.125 mg on Day 1, 2.5 mg on Day 2 and 2.5 mg on Day 3. If indicated, the patient will also have surgical intervention for spinal cord decompression and spinal stabilization. Each patient who takes part in this study will have labs drawn regularly and adverse events assessed daily through Day 14 or discharge (whichever is earlier). Study participation will last for 365 days (+/- 30 days), with post-hospitalization follow-up occurring on Days 28, 42, 84, 182 and 365.

Drug Information available for: Glyburide

Arm Intervention/treatment
Experimental: Glyburide Treatment Arm
Enrolled patients will receive 12 doses of Glyburide starting within 8 hours of SCI. The dosing regimen involves an initial dose of 1.25 mg followed by eleven consecutive doses of 0.625 mg every 6 hours. The total daily dose of Glyburide on Day 1, Day 2 and Day 3 will be 3.125 mg, 2.5 mg, and 2.5 mg respectively.
Drug: Glyburide
3 day drug regimen beginning 8 hours after acute traumatic spinal cord injury.

Primary Outcome Measures :
  1. Rate of recruitment of patients with tSCI within the specified time window [ Time Frame: Enrollment Period (within 8 hours of tSCI) ]
    A measure of feasibility of undertaking a larger phase II study among this population of patients where treatment must begin within a short injury-to-drug time window.

  2. Number of drug related adverse events [ Time Frame: One year post enrollment ]
    A measure of safety of treating patients with traumatic spinal cord injury with Glyburide administered orally within a short injury-to-drug time window.

Secondary Outcome Measures :
  1. Neurologic recovery following tSCI [ Time Frame: One year post enrollment ]
    The neurologic status of patients will be assessed using the American Spinal Injury Association (ASIA) Impairment Scale (AIS) as assessed by International Standards for Neurological Classification of SCI (ISNCSCI) criteria.

  2. Serum pharmacokinetic and biomarker analysis [ Time Frame: Enrollment through post-treatment day 7 ]
    Plasma concentrations will be serially quantified through day 3 following tSCI to evaluate the pharmacokinetics of Glyburide in the acute tSCI population. Comparisons will be made to reported levels achieved in healthy patient cohorts. Standard enzyme-linked immunosorbent assay (ELISA) techniques will be used to measure blood levels of neurofilament light chain, neuron- specific enolase, tau, S100b, and glial fibrillary acidic protein levels on admission, at 24 hours and on days 3 and 7 following tSCI to evaluate serum biomarker levels. Comparisons will be made to previously published values observed in non-treated control patients

  3. Spinal cord lesion imaging analysis [ Time Frame: Enrollment through post-treatment day 2 ]
    Finally, spinal cord lesion volume will be analyzed using standard sequences (including T1 and T2-weighted images) to assess the extent of the hemorrhagic lesion and surrounding edema. Patients will be imaged on the day of admission and on day 2 following injury demarcating a defined time window for assessment of post-tSCI lesion expansion 18. Volumetric assessments of lesion size (based on manual outlines) will be performed and compared at the two time-points by the study neuroradiologist to assess for the progression of intrinsic cord signal changes.

Exclusion Criteria

  1. Unconsciousness or other mental impairment that prevents neurological assessment within the first 8 hours
  2. Acute SCI with ASIA Impairment Scale grade D or E
  3. Currently involved in another non-observational SCI research study or receiving another investigational drug
  4. History of hypersensitivity to sulfonylureas, in particular glyburide, or any of its components
  5. Other illness (including mental disorder) that could preclude accurate medical and neurological evaluation (at discretion of the site investigator)
  6. Unable to commit to the follow-up schedule
  7. A recent history of regular substance abuse (illicit drugs, alcohol), which in the opinion of the investigator would interfere with the subject's participation in the study
