Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
