|---|---|---|---|
| Primary | Change From Baseline of Mean Latency to Persistent Sleep (LPS) Over the Last 2 Nights of 1 Month of Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Days 29 and 30 | LPS was defined as the time in minutes from lights off to the first epoch of 20 consecutive epochs of non- wakefulness as measured by polysomnography (PSG). Change from baseline to average LPS on Days 29 and 30 was reported. The outcome measure was planned to be assessed for randomization phase only. |

Change from baseline to average SE on Days 29 and 30 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline in Mean Objective Wake After Sleep Onset (WASO) Over the Last 2 Nights of 1 Month Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Days 29 and 30 | WASO was defined as minutes of wake from the onset of persistent sleep until lights on as measured by PSG. Change from baseline to average WASO on Days 29 and 30 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline of Subjective Sleep Onset Latency (sSOL) Over the Last 7 Nights of 1 Month Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Nights 24 to 30 | sSOL was defined as estimated minutes from the time that the participant attempted to sleep until sleep onset. Change from baseline to average sSOL of Nights 24 to 30 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline of Subjective Sleep Efficiency (sSE) Over the Last 7 Nights of 1 Month of Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Nights 24 to 30 | sSE was defined as percentage of subjective total sleep time (sTST) divided by subjective time spent in bed, calculated as the interval from the time the participant reported attempting to sleep until the time participant stopped trying to sleep for the night (operationalized as the time the participant got out of bed for the day), and time spent asleep derived from subjective time spent in bed minus subjective wake after sleep onset (sWASO). WASO: estimated minutes of wake at night after initial sleep onset to time stopped trying to sleep for the night. Change from baseline to average sSE of Nights 24 to 30 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline in Subjective Wake After Sleep Onset Over the Last 7 Nights of 1 Month Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Nights 24 to 30 | sWASO was defined as sum of estimated minutes of wake during the night after initial sleep onset until the time the participant stopped trying to sleep for the night, operationalized as the time the participant got out of bed for the day. Change from baseline to average sWASO of Nights 24 to 30 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline of Mean Latency to Persistent Sleep Over the First 2 Nights of 1 Month of Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Nights 1 and 2 | LPS was defined as the time in minutes from lights off to the first epoch of 20 consecutive epochs of non- wakefulness as measured by polysomnography. Change from baseline to average LPS on Nights 1 and 2 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline of Mean Sleep Efficiency Over the First 2 Nights of 1 Month of Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Nights 1 and 2 | SE was defined as percentage of time spent in bed asleep, calculated as total sleep time divided by interval from lights off until lights on as measured by PSG, multiplied by 100. Change from baseline to average SE on Nights 1 and 2 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline of Mean Wake After Sleep Onset Over the First 2 Nights of 1 Month of Treatment of Lemborexant 10 mg Compared to Placebo | Baseline, Nights 1 and 2 | WASO was defined as minutes of wake from the onset of persistent sleep until lights on as measured by PSG. Change from baseline to average WASO on Nights 1 and 2 was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) | From the first dose of study drug up to 44 days | A TEAE was defined as an AE with onset date on or after the first dose of study drug up to 14 days after the last dose of study drug. An SAE was any untoward medical occurrence that at any dose: resulted in death, was life-threatening (that is, participant was at immediate risk of death from AE as it occurred; this did not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death), required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect (in the child of a participant who was exposed to the study drug). The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline in Insomnia Severity Index (ISI) Total Score After 1 Month of Treatment With Lemborexant 10 mg Compared to Placebo | Baseline to Day 31 | The ISI was a 7-item self-report questionnaire assessing the nature, severity, and impact of insomnia. The 7 dimensions evaluated are severity of: sleep onset; sleep maintenance; early-morning awakening problems; sleep dissatisfaction; interference of sleep difficulties with daytime functioning; noticeability of the sleep problems by others; and distress caused by the sleep difficulties. A 5-point Likert scale is used to rate each item (from 0= no problem, 1= satisfied, 2= moderately satisfied, 3= dissatisfied and 4=very severe problem). Total ISI score was calculated as sum of scores of all 7 individual items, ranging between 0 to 28. A higher score indicated more severe illness. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline in Insomnia Severity Index Daytime Functioning Score After 1 Month of Treatment With Lemborexant 10 mg Compared to Placebo | Baseline to Day 31 | The ISI is a 7-item self-report questionnaire assessing the nature, severity, and impact of insomnia. The 4 dimensions out of 7 evaluated for daily functioning are severity of: sleep dissatisfaction; interference of sleep difficulties with daytime functioning; noticeability of the sleep problems by others; and distress caused by the sleep difficulties. A 5-point Likert scale is used to rate each item (from 0= no problem, 1= satisfied, 2= moderately satisfied, 3= dissatisfied and 4=very severe problem), Daytime Functioning score was calculated as sum of scores of item 4 to 7, ranging between 0 to 16. A higher score indicated more severe illness. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Number of Participants With Rebound Insomnia on Average of First 3 Nights (Nights 31 to 33), Average of First 7 Nights (Nights 31 to 37), and Average of Last 7 Nights (Nights 38 to 44) During the Follow-up Period | First 3 nights (Nights 31 to 33), First 7 nights (Nights 31 to 37) and Last 7 nights (Nights 38 to 44) of Follow up Period | Rebound insomnia was defined as worsened sleep relative to screening after study drug treatment was completed. Sleep diary data from the follow-up period was compared to sleep diary data from the screening period to assess whether participants experience rebound insomnia. Number of participants with rebound insomnia assessed by sleep diary (sSOL and sWASO) was reported. The outcome measure was planned to be assessed for randomization phase only. |
| Secondary | Change From Baseline in Mean Morning Residual Sleepiness Score Evaluated During Treatment and Follow-up Periods | Baseline, First 7 mornings (Mornings 1 to 7) and Last 7 mornings (Mornings 24 to 30) of Treatment period; First 7 mornings (Mornings 31 to 37) and Last 7 mornings (Mornings 38 to 44) of Follow-up period | The Sleep Diary was used to assess subjective ratings of morning sleepiness with the following question: "How sleepy/alert do you feel this morning?" Participants rated their sleepiness/alertness level on a Likert scale from 1 to 9, with 1 being extremely poor (sleepy) and 9 being extremely good (alert). Higher score indicated better outcome. Change from baseline of the morning sleepiness item on the sleep diary for the average of first 7 mornings and the average of last 7 mornings of the Treatment Period; and the average of the first 7 mornings and the average of the last 7 mornings of the Follow-up Period was reported. The outcome measure was planned to be assessed for randomization phase only. |
