Trial Outcomes & Findings for Efficacy and Tolerability of Armodafinil in Adults With Excessive Sleepiness Associated With Shift Work Disorder (NCT NCT01080807)

NCT ID: NCT01080807

Last Updated: 2012-06-20

Results Overview

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).

• Recruitment status: COMPLETED
• Study phase: PHASE4
• Target enrollment: 385 participants
• Primary outcome timeframe: Baseline and week 6 (or last observation after baseline)

Participant Flow

385 patients at 45 centers in the US met entry criteria and were considered eligible for enrollment into the study; 2 of these patients enrolled twice under different identification numbers. Of the 383 patients enrolled, 371 received at least 1 dose of study drug and were evaluated for safety; 12 patients withdrew before taking any study drug.

The study consisted of a 1- to 3-week screening period, a 1-week baseline period (followed by randomization), and a 6-week double-blind treatment period.

Participant milestones

Measure	150 mg/Day Armodafinil 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.	Matching Placebo 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.

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.

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.

Population: Full analysis set defined as subjects who were assessed with MSDS at baseline and at Endpoint.

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.

TSQM is a 14 question questionnaire assessing satisfaction with the medication. 4 scales are generated: side effects, effectiveness, convenience, and global satisfaction. Subjects responded to the questionnaire at Week 3, Week 6, and last observation after baseline. Optional responses are: Extremely Dissatisfied, Very Dissatisfied, Dissatisfied, Somewhat Satisfied, Satisfied, Very Satisfied, and Extremely Satisfied.

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.
