Traumatic Brain Injury | Drug: Placebo Drug: citicoline | Phase 3 |
Traumatic brain injury (TBI) is a major cause of death and disability. In the United States alone approximately 1.4 million sustain a TBI each year, of which 50,000 people die, and over 200,000 are hospitalized. Despite numerous prior clinical trials no standard pharmacotherapy for the treatment of TBI has been established in either the acute or post acute setting. Citicoline is a naturally occurring endogenous compound. This compound offers the potential of employing neuroprotection, neuro-recovery and neurofacilitation to enhance recovery after TBI.
The primary goal of this study is to assess the efficacy of citicoline compared to placebo on functional and cognitive outcome in participants with traumatic brain injury.

Arm | Intervention/treatment |
---|---|
Experimental: Placebo
Placebo tablets formulated to resemble the citicoline treatment.
|
Drug: Placebo
Drug Placebo Inactive twice a day given orally or enterally. The first dose is given within 24 hours of injury and treatment continues until 90 days or until the 90-day outcome assessment.
|
Experimental: Citicoline
Experimental treatment administered orally or enterally depending upon whether the participant can swallow at 1,000 mg twice a day for 90 days or until the 90-day outcome assessment.
|
Drug: citicoline
1000 mg twice a day orally or enterally. The first dose is within 24 hours of injury and treatment continues for 90-days or until the 90-day outcome assessment.
Other Name: CDP-Choline, Cytidine 5-diphosphocholine, Somazina

- Functional and Cognitive Outcome [ Time Frame: 90 days ]The primary outcome of this study was analyzed using a global statistic of the Network Core Battery. There were 9 scales: California Verbal Learning Test II (CVLT-II); Controlled Oral Word Association Test (COWAT); Digit Span (DS); Glasgow Outcome Scale Extended (GOSE); Processing Speed Index (PSI); Stroop Test 1 and 2 (ST1&2); and Trail Making Test part A and B (TMT parts A and B). Each scale was assigned cut-off for good outcome: GOSE>7, CVLT>36, PSI>85, TMT part A <42, TMT part B<138.1, DS>7.15, ST1<60.29, ST2<151.47, COWAT>32.5. Logistic regression was used to estimate the global OR.
