ListOutcomeTime frameDescription
PrimaryChange From Baseline in Mean Latency to Persistent Sleep (LPS) of Lemborexant 10 mg and Lemborexant 5 mg Compared to Placebo on Days 29/30Baseline, Days 29/30
LPS is defined as the time in minutes from lights off to the first epoch of 20 consecutive epochs of non- wakefulness as measured by PSG. Change from baseline to average LPS on Day 29 and 30 was reported.
SecondaryChange From Baseline in Mean Sleep Efficiency (SE) of Lemborexant 10 mg and Lemborexant 5 mg Compared to Placebo on Days 29/30Baseline, Days 29/30
SE is defined as percentage of time spent in bed asleep, calculated as total sleep time (TST) divided by interval from lights off until lights on as measured by PSG, multiplied by 100. Change from baseline to average SE on Day 29 and 30 was reported.
SecondaryChange From Baseline in Mean Wake After Sleep Onset (WASO) of Lemborexant 10 mg and Lemborexant 5 mg Compared to Placebo on Days 29/30Baseline, Days 29/30WASO is 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.
SecondaryChange From Baseline in WASO in the Second Half of the Night (WASO2H) of Lemborexant 10 mg and Lemborexant 5 mg Compared to Zolpidem ER on Days 29/30Baseline, Days 29/30
WASO2H is defined as time in minutes of wake during the interval from 240 minutes after lights off until lights on as measured by PSG. Change from baseline to average WASO2H on Days 29 and 30 was reported.
OtherChange From Baseline in Mean Body Sway Upon Awakening in the Morning for Lemborexant 5 mg and Lemborexant 10 mg Compared to Zolpidem ER on Days 2/3Baseline, Days 2/3
Body sway is detected through a cable around the participant's waist by the ataxia meter. Body sway is measured in units of one-third degree of the angle of arc. For ease in reporting, these are called arbitrary units, with a higher number indicating more body sway (less postural stability). Change from baseline in mean body sway on Days 2 and 3 was reported.
OtherChange From Baseline in Mean LPS, WASO, and TST of Lemborexant 10 mg and Lemborexant 5 mg Compared to Zolpidem ER on Days 1/2 and Days 29/30Baseline, Days 1/2, and Days 29/30
LPS is defined as the time in minutes from lights off to the first epoch of 20 consecutive epochs of non-wakefulness as measured by the PSG. WASO is defined as minutes of wake from the onset of persistent sleep until lights on as measured by PSG. TST is defined as the amount of sleep in minutes from LPS until terminal awakening as measured by PSG. Change from baseline to average LPS, WASO, and TST on Days 1 and 2, and Days 29 and 30 were reported.
Other
Change From Baseline in Subjective Sleep Onset Latency (sSOL), Subjective Wake After Sleep Onset (sWASO) and Subjective Total Sleep Time (sTST) of Lemborexant 10 mg and Lemborexant 5 mg Compared to Zolpidem ER
First 7 nights (approximately Week 1) and Last 7 nights (approximately Week 4)
sSOL: estimated minutes from time attempted to sleep to sleep onset. sWASO: estimated minutes of wake at night after initial sleep onset to time stopped trying to sleep for the night. sTST: minutes of sleep from sleep onset to time stopped trying to sleep for the night. sSOL, sWASO, sTST were analyzed with diary handling rules (DHR) on an electronic sleep diary. Subjective measures were derived from sleep diaries entries, collected daily and analyzed at appropriate intervals.
OtherChange From Baseline in Subjective Sleep Efficiency (sSE) of Lemborexant 10 mg and Lemborexant 5 mg Compared to Zolpidem ERFirst 7 nights (approximately Week 1) and Last 7 nights (approximately Week 4)
sSE: percentage of sTST per subjective time spent in bed asleep, calculated as the interval from the time attempted to sleep to time stopped trying to sleep for the night, and time spent asleep derived from subjective time spent in bed minus sWASO. sWASO: estimated minutes of wake at night after initial sleep onset to time stopped trying to sleep for the night. sSE was analyzed with DHR on an electronic sleep diary. Subjective measures were derived from sleep diaries entries, collected daily and analyzed at appropriate intervals.
OtherChange From Baseline in Mean LPS, WASO, WASO2H, and TST of Lemborexant 10 mg and Lemborexant 5 mg Compared to Placebo on Days 1/2Baseline, Days 1/2
LPS: amount of time in minutes from lights off to first epoch of 20 consecutive epochs of non-wakefulness. WASO: amount of time in minutes of wake from the onset of persistent sleep until lights. WASO2H: amount of time in minutes of wake during the interval from 240 minutes after lights off until lights on. TST: amount of time in minutes of sleep from sleep onset until terminal awakening. LPS, WASO, WASO2H, and TST were measured by PSG. Change from baseline to average LPS, WASO, WASO2H, and TST on Day 1 and 2 were reported.
OtherChange From Baseline in Mean SE of Lemborexant 10 mg and Lemborexant 5 mg Compared to Placebo on Days 1/2Baseline, Days 1/2
SE is defined as percentage of time spent in bed asleep, calculated as TST divided by interval from lights off until lights on as measured by PSG, multiplied by 100. Change from baseline to average SE on Day 1 and 2 were reported.
