Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | Baseline and 12 weeks (or last observation after baseline) |

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.

| Change From Baseline on Medical Outcomes Study 6 Item Cognitive Functioning (MOS-CF6) Scale at Endpoint (12 Weeks or Last Observation After Baseline) | The MOS-CF6 assesses self-reported cognitive function. Items were selected to cover 6 relevant aspects of cognitive functioning:confusion, concentration/thinking, attention, memory, reasoning, problem-solving, and processing speed. Responses range from none of the time to all of the time. The MOS-CF6 is scored by summing responses across the 6 items and converting the total to a 0 - 100 point scale, with the higher score indicating better cognitive functioning. Data is presented showing the change in score from baseline to Endpoint (12 weeks or last observation after baseline). | Baseline and Endpoint (12 weeks or last observation after baseline) |

The MOS-CF6 responses includes 6 choices, ranging from none of the time to all of the time. The MOS-CF6 is scored by summing responses across the 6 items and converting the total to a 0 - 100 point scale, with the higher score indicating better cognitive functioning. Data is presented showing the change in score from baseline to 2 weeks. | baseline and 2 weeks |

| Change From Baseline in the Excessive Sleepiness (ES) Symptom Rating Form - Sleepiness Scores at Endpoint (12 Weeks or Last Observation After Baseline) | The Excessive Sleepiness Symptom Rating Form was used to assess symptoms of excessive sleepiness. Patients rate 7 symptoms(tiredness, fatigue, sleepiness, lack of energy, trouble paying attention, forgetfulness, trouble staying organized) on an 11-point Likert scale (0 = no problem at all to 10 = as bad as you can imagine). ES Symptom Rating Form was designed to follow the response to treatment measuring severity of each of these 7 symptoms using the same 11-point scale. Change from Baseline to Endpoint (12 weeks or last baseline observation) is presented only for the symptom of Sleepiness. | Baseline and Endpoint (12 weeks or last observation after baseline) |
