Study of Modafinil to Treat Fatigue in Persons With Traumatic Brain Injury

Condition(s) targeted: Fatigue

Intervention: Modafinil (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Craig Hospital

The purpose of this study is to determine whether Modafinil is effective in: (1) reducing fatigue and excessive daytime sleepiness (EDS) in individuals with Traumatic Brain Injury (TBI); and (2) improving cognitive function and quality of life in individuals with TBI.

Official title: Modafinil for the Treatment of Fatigue and Excessive Daytime Sleepiness in Individuals With Traumatic Brain Injury

Study design: Treatment, Randomized, Double-Blind, Placebo Control, Crossover Assignment, Efficacy Study

Primary outcome:

Self report of fatigue

Self report of EDS

Data collected at baseline, 4 weeks, and 10 weeks (for both phases of crossover study)

Secondary outcome:

Self report of general health

Self report of depressive symptomatology

Performance on tests of cognitive functioning

Data collected at baseline, 4 weeks, and 10 weeks (for both phases of crossover study)

Detailed description: Background: An estimated 5. 3 million Americans are living with a TBI-related disability today. These persons may face many issues, however, two chronic problems seem common to a strikingly large number of those who survive TBI: fatigue and EDS.

Need for Research: Modafinil has been shown to be useful for fatigue and sleepiness in patients with depression, multiple sclerosis, Parkinson's disease and individuals with EDS secondary to a variety of sleep disturbances. However, there has not been any controlled evaluation of Modafinil use for the treatment of individuals with TBI to date.

Current and Future Research Activity: Approximately 60 participants with post-TBI fatigue will be randomly assigned to two 10-week periods of taking either Modafinil or placebo. Participants taking Modafinil during the first 10 weeks will be switched to placebo for the second 10 weeks. Similarly, participants taking placebo during the first 10 weeks will be switched to Modafinil for the second 10 weeks. Outcomes relating to fatigue and EDS will be collected weekly throughout the study. Other outcomes (including general health, depression, and cognitive function) will be collected at the start of each period, 4 weeks into each period, and again at the end of each period. It is hypothesized that participants taking Modafinil will report significantly less fatigue and EDS, report significantly better general health and depression scores, and perform significantly better on tests of cognitive performance in comparison to participants taking placebo.

Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Individuals who sustained a TBI

- were discharged from Craig Hospital following initial rehabilitation

- are at least one year post-injury

- have disabling symptoms of fatigue and/or EDS which compromise their ability to

function optimally

- (if female) are surgically sterile, two years post-menopausal, or if of childbearing

potential, are using a medially acceptable method of birth control and agree to continue use of this method for the duration of the study

Exclusion Criteria:

- Individuals who have Neurologic and/or neuropsychiatric difficulties and/or deficits

which will obscure the evaluation of this medication's effectiveness -

- have a diagnosis of other likely causes of EDS

- have concurrent medication use and/or clinically significant systemic disease that may

cause fatigue and/or diminished arousal

- have epilepsy

- currently use of any anti-epileptic medications or Warfarin

- have cardiovascular disease or risks

- have severe renal or hepatic impairment

- have significant psychiatric or behavioral disturbance which would obscure the

evaluation of medication effectiveness

- are a pregnant or lactating female
