Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline on Maintenance of Wakefulness Test (MWT) to Endpoint (12 Weeks or Last Observation After Baseline)Baseline and 12 weeks (or last observation after baseline)MWT measures ability of subject to remain awake. Subjects instructed to try and remain awake during series of 4 30-minute periods (0900, 1100, 1300, and 1500) reclining in dark room. Each period was terminated immediately after sleep onset or at end of 30 minutes if no sleep occurred. If subject fell asleep, they were awakened and not allowed to sleep for remainder of that 30 minute period. Change from Baseline to Endpoint (12 weeks or last observation after baseline) in mean sleep latency averaged from the 4 intervals was measured. Poorest outcome was 0 minutes the best was 30 minutes.
Clinical Global Impression of Change (CGI-C) at Endpoint (12-weeks or Last Observation After Baseline)12 weeks (or last observation after baseline)The CGI-C is a clinician's rating of disease severity compared with baseline as assessed by Clinical Global Impression of Severity (CGI-S). CGI-C rates improvement by 7 categories: very much improved, much improved, minimally improved, no change, minimally worse, much worse, very much worse. CGI-S measured 7 categories of illness as well: normal, borderline ill, mildly ill, moderately ill, markedly ill, severely ill, among most extremely ill. Proportion of responders who had at least minimally improved in CGI-C ratings (as related to sleepiness) were assessed.

Change From Baseline on Maintenance of Wakefulness Test (MWT) to Endpoint (12 Weeks or Last Observation After Baseline)

MWT measures ability of subject to remain awake. Subjects instructed to try and remain awake during series of 4 30-minute periods (0900, 1100, 1300, and 1500) reclining in dark room. Each period was terminated immediately after sleep onset or at end of 30 minutes if no sleep occurred. If subject fell asleep, they were awakened and not allowed to sleep for remainder of that 30 minute period. Change from Baseline to Endpoint (12 weeks or last observation after baseline) in mean sleep latency averaged from the 4 intervals was measured. Poorest outcome was 0 minutes the best was 30 minutes.

Time frame: Baseline and 12 weeks (or last observation after baseline)

Population: Full analysis set which includes subjects who had at least 1 measurement of MWT or Clinical Global Impression of Change (CGI-C) after baseline.

Clinical Global Impression of Change (CGI-C) at Endpoint (12-weeks or Last Observation After Baseline)

The CGI-C is a clinician's rating of disease severity compared with baseline as assessed by Clinical Global Impression of Severity (CGI-S). CGI-C rates improvement by 7 categories: very much improved, much improved, minimally improved, no change, minimally worse, much worse, very much worse. CGI-S measured 7 categories of illness as well: normal, borderline ill, mildly ill, moderately ill, markedly ill, severely ill, among most extremely ill. Proportion of responders who had at least minimally improved in CGI-C ratings (as related to sleepiness) were assessed.

The Brief Fatigue Inventory (BFI) is a subjective-completed tool for the assessment of the impact of fatigue on daily functioning. Simple numeric rating scales from 0 to 10 are used. The higher scores are associated with more severe fatigue, with \>= 7 indicative of severe fatigue. The worst daily fatigue score reports the outcome of a single item on the BFI that rates the worst fatigue experienced over the day on a scale from 0 to 10 with 0 being no fatigue and 10 being most severe. This measure compares the change in score from baseline to Week 12 (or last observation after baseline).

Change From Baseline on the Epworth Sleepiness Scale (ESS) at Endpoint (12 Weeks or Last Measurement After Baseline)

For this key secondary outcome the ESS score is based on responses to questions (self administered) that assessed the propensity of the subject to fall asleep in 8 everyday situations (sitting and reading, talking to someone, being stopped in traffic, etc.) Scores for the ESS range from 0 to 24, with a higher score indicating greater daytime sleepiness. The change in ESS total score from baseline to Endpoint (12 weeks or last observation after baseline) are summarized.

Change From Baseline to Endpoint (Week 12 or Last Observation After Baseline) in the Brief Fatigue Inventory (BFI) Total Score

The Brief Fatigue Inventory (BFI) is a subjective-completed tool for the assessment of the impact of fatigue on daily functioning. Simple numeric rating scales from 0 to 10 are used. The higher scores are associated with more severe fatigue, with any score \>= 7 considered to be indicative of severe fatigue. The total score is calculated by taking the sum of all 9 rating scales for a minimum score of 0 and a maximum score of 90. This assessment examines the difference in total BFI score from Baseline to 12 weeks or last observation after baseline.
