Primary Outcome Measures
NameTimeMethod
Change in Maintenance of Wakefulness Test (MWT) From Baseline to Week 12Baseline to Week 12

Change in mean sleep latency time (in minutes) as determined from the first 4 trials of a 40-minute MWT from baseline to Week 12.

Change in ESS Score From Baseline to Week 12Baseline to Week 12

Change in Epworth Sleepiness Scale (ESS) score from Baseline to Week 12. A negative change from baseline represents improvement in excessive sleepiness.

The ESS is a self-administered questionnaire with 8 questions. Each activity is scored on a scale ranging from 0-3, with 0 = would never fall asleep, and 3 = high chance of falling asleep. The total score ranges from 0-24, with a higher number representing an increased propensity for sleepiness. An analysis of covariance (ANCOVA) was used for the analysis of ESS scores. The response variable was the change in ESS score from baseline.

Secondary Outcome Measures
NameTimeMethod
Subjects Reported Improved on the Patient Global Impression of Change (PGIc) at Week 1212 Weeks

Percentage of subjects reported as improved (minimally, much, or very much) on the PGIc at Week 12. PGIc was rated by subjects and measures the change in their condition since start of treatment on a 7-point scale ranging from 1 = very much improved to 7 = very much worse.

This is the key secondary endpoint.

Change in Sleep Latency Time on Each of the 5 MWT Trials at Week 12Baseline and Week 12

Time course of efficacy in MWT: Change in sleep latency (in minutes) on each of the 5 MWT trials at week 12.

Change in the Mean Sleep Latency Time as Determined From the First 4 Trials of a 40-minute MWT From Baseline to Week 4Baseline to Week 4

Change in mean sleep latency time (in minutes) as determined from the first 4 trials of a 40-minute MWT from baseline to week 4.

Change in ESS Score From Baseline to Week 1, Week 4, and Week 8Baseline to Weeks 1, 4, and 8

Change in Epworth Sleepiness Scale (ESS) score from Baseline to Weeks 1, 4, and 8. A negative change from baseline represents improvement in excessive sleepiness.

The ESS is a self-administered questionnaire with 8 questions. Each activity is scored on a scale ranging from 0-3, with 0 = would never fall asleep, and 3 = high chance of falling asleep. The total score ranges from 0-24, with a higher number representing an increased propensity for sleepiness. An analysis of covariance (ANCOVA) was used for the analysis of ESS scores. The response variable was the change in ESS score from baseline.

Percentage of Subjects Reported as Improved on the PGIc at Week 1, Week 4, and Week 8Weeks 1, 4, and 8

Percentage of subjects reported as improved (minimally, much, or very much) on the PGIc at Week 1, Week 4, and Week 8. PGIc was rated by subjects and measures the change in their condition since treatment start on a 7-point scale ranging from 1 = very much improved to 7 = very much worse.

Percentage of Subjects Reported as Improved on the Clinical Global Impression of Change (CGIc) at Week 12Week 12

Percentage of subjects reported as improved (minimally, much, or very much) on the CGIc at Week 12. CGIc was rated by clinicians and measures the change in the subject's condition since treatment starts on a 7-point scale ranging from 1= very much improved to 7= very much worse.

Percentage of Subjects Reported as Improved on the CGIc at Week 1, Week 4, and Week 8Weeks 1, 4, and 8

Percentage of subjects reported as improved (minimally, much, or very much) on the CGIc at Week 1, Week 4, and Week 8. CGIc was rated by clinicians and measures the change in the subject's condition since treatment starts on a 7-point scale ranging from 1= very much improved to 7= very much worse.
