Details and patient eligibility

About

This study aim to evaluate whether a dose of 5 mg of lemborexant, as compared to a placebo, may improve daytime recovery sleep, without producing lingering sleepiness during wakefulness, using a 3-day simulated night shift protocol in the lab under constant monitoring.

Full description

After being informed about the study and potential risks, all patients giving written informed conset will undergo 2 screening visits to determine eligibility for study entry. Selected participants will then stay twice in the lab (active treatment condition and placebo condition), each visit lasting approximately 4 days. Participants will stay awake across the night and sleep during the day. Only the experimental condition will be different between the two visits (lemborexant or placebo). These experimental visits will be double-blind, in counterbalanced order and separated by an interval of at least 2 weeks (washout period).

Presence of a sleep disorder, such as a diagnosis of insomnia, narcolepsy, sleep paralysis, active somnambulism (history of childhood somnambulism is accepted), hypnagogic/ hypnopompic hallucinations, and REM behavior disorder, will be excluded based on the clinical interview. For sleep apnea syndrome, an apnea-hypopnea index > 15 per hour of sleep on the first screening night will be used as an exclusion criterion.
