The primary objective of the study is to determine whether armodafinil treatment is more effective than placebo treatment in patients with excessive sleepiness associated with shift work disorder (SWD) by measuring improved clinical condition late in the shift, including the commute home.

At the baseline visit, patients who continued to meet eligibility criteria were randomly assigned (1:1) to receive either 150 mg of armodafinil or matching placebo treatment only on nights worked for 6 weeks. Study drug was taken once nightly, 30 to 60 minutes prior to the start of the night shift, on nights worked. Armodafinil treatment was titrated as follows (only on nights worked): the first dose was 50 mg (1 tablet), the second and third doses were 100 mg (2 tablets), and the fourth and subsequent doses were 150 mg (3 tablets). Placebo tablets matching armodafinil tablets were administered on the same schedule.

Percentage of Patients With at Least Minimal Improvement From Baseline in the Clinical Global Impression of Change (CGI-C) Rating as Related to Late Shift Sleepiness at Endpoint
The Clinical Global Impression of Change (CGI-C) is an assessment performed by the clinician, evaluating the change in the patient's symptoms over time. The clinician categorizes the change as: very much improved, much improved, minimally improved, no change, minimally worse, much worse, or very much worse. The data presented here represents the percentage of patients whose condition showed at least minimal improvement in the CGI-C rating as related to late shift sleepiness (defined as the period 0400-0800, including the commute home).

Change From Baseline to Endpoint in Global Assessment of Function (GAF) Score
The Global Assessment of Functioning (GAF) is a numeric scale (0 through 100) used by the clinician to rate the social, occupational, and psychological functioning of the patient. A higher score indicates superior functioning and fewer symptoms. The data presented here represents the mean change from baseline to endpoint in the GAF scores of each group.
Time frame: Baseline and week 6 (or last observation after baseline)

Change From Baseline to Endpoint in the Mean Karolinska Sleepiness Scale (KSS) Score
The Karolinska sleepiness scale is a 10-point scale, on which the participant has to mark his sleepiness during the previous 10 minutes. The scale ranges from 1, which indicates "extremely alert", to 10, which indicates "extremely sleepy, can't stay awake". The KSS was performed by the participant at the baseline visit, week 3, and week 6 (or early termination visit). The score recorded is the average of 3 assessments within ±15 minutes at 0400, 0600, and 0800. The data presented here represents the mean change from baseline in the KSS scores of each group.

Change From Baseline to Endpoint in the Modified Sheehan Disability Scale (MSDS) Composite Score
Mental-health related disability was assessed with the Modified Sheehan Disability Scale (MSDS). The MSDS has three 11-point items, and the participant is asked to rate, on a numerical scale, the extent to which emotional problems have disrupted her/his work, social life, and family life/home responsibilities over the last month. Each item is rated from 0, indicating "not at all", to 10, indicating "extremely". Scores for the items are summed for a possible score of 0 to 30. The MSDS was performed by the patient at the baseline visit, at Week 3, and at Week 6.

Change From Baseline to Endpoint in the Functional Outcomes of Sleep Questionnaire (FOSQ-10) Total Score
FOSQ-10 consists of 10 questions, on a scale of 1-4(1=extreme difficulty 4=no difficulty), measures impact of sleepiness on activities of daily living. Lower score = more difficulty with activity due to lack of sleep. Total score = MEAN of subscale scores (vigilance, productivity, social outcome, intimacy, activity) multiplied by 5. Worst total score is 5 (maximum difficulty) the best is 20 (no difficulty). This data reports CHANGE in total score from baseline to endpoint, with higher (positive) values representing improvement. Worst possible CHANGE value would be -15 best would be +15.
Time frame: Baseline and week 6 (or last observation after baseline)
