Patients with a diagnosis of moderate to severe traumatic brain injury (TBI) will be enrolled. Subjects will be randomly assigned to receive either MLC901 (Specified Drug Code) or placebo capsules three times per day over 6 months. Evaluation of patients will be carried out at baseline as well as at 3-month and 6-month follow-up visits. Modified Rankin Scale (mRS) and Glasgow outcome scale (GOS) will be used to examine patients. Efficacy will be evaluated by comparing these two scores between the 2 groups at follow-up visits.

Inclusion Criteria:

• age between 15 and 65
• non-penetrating moderate (Glasgow Coma Scale score [GCS] 9-12) or severe (GCS 3-8) traumatic brain
• injury less than 24 hrs from traumatic injury
• anticipated intensive care unit length of stay at least 48 hrs

Exclusion Criteria:

• GCS = 3 and fixed dilated pupils or penetrating injury
• coexisting injury or medical conditions which could adversely affect our study outcome measures
• dependence for everyday activities before the injury
• pregnancy or breastfeeding
• known allergy to any of MLC901 components
