Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in ESS Score From Baseline to Week 4 | Baseline to Week 4 | Change in Epworth Sleepiness Scale (ESS) score from Baseline to Week 4. 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Subjects Reported Improved on the Patient Global Impression of Change (PGIc) at Week 4 | Baseline to Week 4 | Percentage of subjects reported as improved (minimally, much, or very much) on the PGIc at Week 4. PGIc is 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 |
