Primary | Probability of Having Utility Function Greater Than (>) 1 Based on Bayesian Analysis | The utility of a dose was a function of both Sleep Efficiency (SE) and Karolinska Sleepiness Scale (KSS), constructed by specifying the 1-dimensional component for each outcome measure and then combining them multiplicatively. Sufficient utility was defined as a probability of having utility function >1. Probability of having utility function >1 at the end of study visit (full analysis) was reported. | Baseline up to Day 3 | |
Primary | Mean Change From Baseline in Karolinska Sleepiness Scale (KSS) Score at End of Treatment | The KSS was used to measure next-day residual effects at prespecified time points. The KSS was a 9-point scale on which the participant rated their sleepiness from 1 (extremely alert) to 9 (extremely sleepy/fighting sleep), where higher scores indicated an increase in sleepiness. The end of treatment score was calculated by the mean scores at the timepoint at 1 hour after morning wake time of Day 15 and 16. | 1 hour after morning wake time at Baseline and Days 15-16 | |
Secondary | Mean Change From Baseline in Sleep Efficiency (SE) After Dosing on Days 1-2 and Days 14-15 | Sleep efficiency was calculated as total sleep time divided by time spent in bed multiplied by 100. An increase in SE indicated improvement in sleeping, such that, the participant spends more time in bed asleep. Mean scores of Days 1-2 and Days 14-15 were used to evaluate change from baseline. | Baseline, Days 1-2, and Days 14-15 | |
Secondary | Mean Change From Baseline in Latency to Persistent Sleep (LPS) After Dosing on Days 1-2 and Days 14-15 | LPS was calculated as minutes from lights off to the first 30-second epoch of 20 consecutive epochs of non-wakefulness. A decrease in LPS indicated improvement in time needed to fall asleep. Mean scores of Days 1-2 and Days 14-15 were used to evaluate change from baseline. | Baseline, Days 1-2, and Days 14-15 | |
Secondary | Mean Change From Baseline in Wakefulness After Sleep Onset (WASO) After Dosing on Days 1-2 and Days 14-15 | WASO was calculated as minutes of wakefulness from the onset of persistent sleep until lights on. A decrease in WASO indicated improvement in sleep maintenance. Mean scores of Days 1-2 and Days 14-15 were used to evaluate change from baseline. | Baseline, Days 1-2, and Days 14-15 | |
Secondary | Potential Habituation Effect: Comparison Between Mean Change From Baseline in SE on Days 1-2 and Mean Change From Baseline in SE on Days 14-15 | Potential habituation effect evaluated the possibility of participants being habituated to changes in sleep during the 15 days of treatment with lemborexant. Data reported here was calculated as change from baseline of mean SE of Days 14-15 minus change from baseline of mean SE of Days 1-2. An increase in SE indicated improvement in sleeping, such that, the participant spends more time in bed asleep. | Baseline, Days 1-2, and Days 14-15 | |
Secondary | Potential Habituation Effect: Comparison Between Mean Change From Baseline in Latency to Persistent Sleep (LPS) on Days 1-2 and Mean Change From Baseline in LPS on Days 14-15 | Potential habituation effect evaluated the possibility of participants being habituated to changes in sleep during the 15 days of treatment with lemborexant. Data reported here was calculated as change from baseline of mean LPS of Days 14-15 minus change from baseline of mean LPS of Days 1-2. LPS was calculated as minutes from lights off to the first 30-second epoch of 20 consecutive epochs of non-wakefulness. A decrease in LPS indicated improvement in time needed to fall asleep. | Baseline and Days 1-2, and Days 14-15 | |
Secondary | Potential Habituation Effect: Comparison Between Mean Change From Baseline in Wakefulness After Sleep Onset (WASO) on Days 1-2 and Mean Change From Baseline in WASO on Days 14-15 | Potential habituation effect evaluated the possibility of participants being habituated to changes in sleep during the 15 days of treatment with lemborexant. Data reported here was calculated as change from baseline of mean WASO of Days 14-15 minus change from baseline of mean WASO of Days 1-2. WASO was calculated as minutes of wakefulness from the onset of persistent sleep until lights on. A decrease in WASO indicated improvement in sleep maintenance. | Baseline, Days 1-2, and Days 14-15 | |
Secondary | Rebound Insomnia: Mean Change From Baseline in Sleep Efficiency (SE) After Dosing on Days 16-17 | Rebound insomnia was assessed by comparing the change from baseline of the mean SE on Days 16-17. Sleep efficiency was calculated as total sleep time divided by time spent in bed multiplied by 100. An increase in SE indicated improvement in sleeping, such that, the participant spends more time in bed asleep. A negative change from baseline in SE indicated that SE was worse on Days 16 and 17 than at Baseline, which was considered as evidence for rebound insomnia. | Baseline and Days 16-17 | |
Secondary | Percentage of Participants With Treatment-emergent Adverse Event (TEAE) and Serious Adverse Event (SAE) | TEAEs: Baseline up to Day 30, SAEs: Baseline up to 30 days after last dose of study drug (up to 47 days) | ||
Secondary | Number of Participants With Clinically Significant Change From Baseline in Clinical Laboratory Parameters | Baseline up to Day 30 | ||
Secondary | Number of Participants With Clinically Significant Change From Baseline in Vital Signs | Baseline up to Day 30 | ||
Secondary | Number of Participants With Clinically Significant Change From Baseline in Electrocardiogram (ECGs) | Baseline up to Day 30 |
