The aim of this study is to evaluate efficacy and safety of riluzole in the treatment of patients with acute SCI. The primary objective is to evaluate the superiority of riluzole, at a dose of 2 x 100 mg the first 24 hours followed by 2 x 50 mg for the following 13 days after injury, as compared to placebo, in change between 180 days and baseline in motor outcomes as measured by International Standards for Neurological Classification of Spinal Cord Injury Examination (ISNCSCI) Motor Score, in patients with acute traumatic SCI, presenting to the hospital less than 12 hours after injury. Secondary objectives are to evaluate the effects of riluzole on overall neurologic recovery, sensory recovery, functional outcomes, quality of life outcomes, health utilities, mortality, and adverse events. The working hypothesis is that the riluzole treated subjects will experience superior motor, sensory, functional, and quality of life outcomes as compared to those receiving placebo, with an acceptable safety profile.

  • Active liver disease or clinical jaundice
  • Acquired immune deficiency syndrome (AIDS) or AIDS-related complex
  • Active malignancy or history of invasive malignancy within the last five years, with the exception of superficial basal cell carcinoma or squamous cell carcinoma of the skin that has been definitely treated. Patients with carcinoma in situ of the uterine cervix treated definitely more than 1 year prior to enrollment may enter the study
