SECONDARY outcome

Timeframe: Baseline to Weeks 1, 2, 3, and 4

Population: The modified Intent-to-Treat population is defined as all randomized subjects who took at least one dose of study drug and have a Baseline and at least one post-Baseline efficacy assessment. Two subjects who did not have at least one post-baseline efficacy data were excluded from the mITT Population, resulting in a total of 64 subjects.

Change from Baseline ESS defined in terms of change from study baseline (prior to first dose in Period 1) to the end of each Treatment Period (Weeks 1, 2, 3, and 4). The Epworth Sleepiness Scale (ESS) is a self-administered questionnaire with 8 questions, asking subjects how likely they would be to doze off or fall asleep in different situations. Responses range from 0 = would never doze to 3 = high chance of dozing. Higher scores represent greater severity of excessive sleepiness. The total score ranges from 0 - 24, with higher scores representing greater severity of excessive sleepiness.

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline to Weeks 1, 2, 3, and 4

Population: The MWT analysis evaluated results from subjects in the mITT population who were in Group 1 only (N=53 subjects).

Change from Baseline mean sleep latency (in minutes) on the MWT defined in terms of change from study baseline (prior to first dose in Period 1) to the end of each Treatment Period (Weeks 1, 2, 3, and 4). The MWT is the standard objective measure of an individual's ability to remain awake during the daytime in a darkened, quiet environment. MWT sleep latency ranges from 0 to 40 minutes, with higher scores indicated greater ability to stay awake.
