Study Summary

This study will be conducted to determine the dose response of lemborexant (LEM) on the change from baseline in actigraphy-derived sleep-related parameters, wake-related parameters, and circadian-rhythm related parameters. Following the eligibility screening period, eligible participants will be assigned at random to 1 of 4 doses of LEM or to placebo for 4 weeks. After a 2-week follow-up period, eligible participants may enter an open-label extension period for up to 30 months or until the program discontinuation.

Primary Outcome

aSE was defined as the percentage of time spent in bed nocturnal sleeping, as measured by actigraphy. Sleep efficiency was calculated as the total duration of sleep epochs during the predefined 8-hour nocturnal sleep period divided by 8 hours and multiplied by 100. Higher values were better. Actigraphy was performed with an accelerometer that was worn on the wrist like a watch. It was programmed to monitor degree and intensity of movements while the device was being worn.
