Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Maintenance of Wakefulness Test (MWT) From Baseline 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. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicating greater ability to stay awake; a positive change from baseline represents improvement in the sleep latency time. Mean sleep latency defined as the average of the first 4 MWT trials, if 3 or 4 of them are non-missing.	Baseline to Week 12
Primary	Change in ESS Score From Baseline 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.	Baseline to Week 12
Secondary	Subjects Reported Improved on the Patient Global Impression of Change (PGIc) at Week 12	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 treatment starts on a 7-point scale ranging from 1= very much improved to 7= very much worse	Baseline to Week 12
Secondary	Change in Sleep Latency Time on MWT Trial 1 at 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 from baseline for sleep latency in MWT during trial 1 at week 12
Secondary	Change in Sleep Latency Time on MWT Trial 2 at 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 from baseline for sleep latency in MWT during trial 2 at week 12
Secondary	Change in Sleep Latency Time on MWT Trial 3 at 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 from baseline for sleep latency in MWT during trial 3 at week 12
Secondary	Change in Sleep Latency Time on MWT Trial 4 at 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 from baseline for sleep latency in MWT during trial 4 at week 12
Secondary	Change in Sleep Latency Time on MWT Trial 5 at 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 from baseline for sleep latency in MWT during trial 5 at week 12
Secondary	Change in the Mean Sleep Latency Time as Determined From the First 4 Trials of a 40-Minute MWT From Baseline 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.	Baseline to Week 4
