Primary Outcome Measures
NameTimeMethod
Change From Baseline to Month 1 in Wake After Sleep Onset (WASO) (Sleep Maintenance)From baseline to Month 1 (i.e. for up to 1 month)

"Wake After Sleep Onset" is the time spent awake after onset of persistent sleep until lights on, as determined by polysomnography.

Change From Baseline to Month 3 in Wake After Sleep Onset (WASO)From baseline to Month 3 (i.e. for up to 3 months)

"Wake After Sleep Onset" is the time spent awake after onset of persistent sleep until lights on, as determined by polysomnography.

Change From Baseline to Month 3 in Latency to Persistent Sleep (LPS)From baseline to Month 3 (i.e. for up to 3 months)

"Latency to Persistent Sleep" is the time from start of recording to the beginning of the first continuous 20 epochs (i.e., 10 minutes) scored as non-awake, i.e., epochs scored as either sleep stage 1 (S1), sleep stage 2 (S2), sleep stage 3 (slow wave sleep) or REM, as determined by polysomnography.

Change From Baseline to Month 1 in Latency to Persistent Sleep (LPS) (Sleep Onset)From baseline to Month 1 (i.e. for up to 1 month)

"Latency to Persistent Sleep" is the time from start of recording to the beginning of the first continuous 20 epochs (i.e., 10 minutes) scored as non-awake, i.e., epochs scored as either sleep stage 1 (S1), sleep stage 2 (S2), sleep stage 3 (slow wave sleep) or REM, as determined by polysomnography.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline to Month 3 in the Subjective Total Sleep Time (sTST)From baseline to Month 3 (i.e. for up to 3 months)

"Subjective Total Sleep Time" is the total sleep time reported by the participant in the sleep diary questionnaire. A positive change from baseline indicates an increase in the subjective Total Sleep Time. A negative change from baseline indicates a decrease in subjective Total Sleep Time.

Change From Baseline to Month 1 in Insomnia Daytime Symptoms and Impacts Questionnaire (IDSIQ) Sleepiness Domain ScoreFrom baseline to Month 1 (i.e. for up to 1 month)

The Insomnia Daytime Symptoms and Impacts Questionnaire (IDSIQ) is a validated patient reported outcome instrument comprising 14 items (each using a numeric rating scale from 0 to 10) grouped into three domains (i.e., sleepiness, mood, and alert/cognition) reflecting daytime impairment of insomnia. The IDSIQ sleepiness domain has 4 items, and the domain score ranges from 0 to a maximum of 40, where a higher score indicates a greater burden. A negative change from baseline indicates an improvement and a positive change from baseline indicates a worsening.

Change From Baseline to Month 3 in IDSIQ Sleepiness Domain ScoreFrom baseline to Month 3 (i.e. for up to 3 months)

The Insomnia Daytime Symptoms and Impacts Questionnaire (IDSIQ) is a validated patient reported outcome instrument comprising 14 items (each using a numeric rating scale from 0 to 10) grouped into three domains (i.e., sleepiness, mood, and alert/cognition) reflecting daytime impairment of insomnia. The IDSIQ sleepiness domain has 4 items, and the domain score ranges from 0 to a maximum of 40, where a higher score indicates a greater burden. A negative change from baseline indicates an improvement and a positive change from baseline indicates a worsening.

Change From Baseline to Month 1 in the Subjective Total Sleep Time (sTST)From baseline to Month 1 (i.e. for up to 1 month)

"Subjective Total Sleep Time" is the total sleep time reported by the participant in the sleep diary questionnaire. A positive change from baseline indicates an increase in the subjective Total Sleep Time. A negative change from baseline indicates a decrease in subjective Total Sleep Time.
