Official title
A Multi-center, Double-blind, Randomized, Placebo-controlled, Parallel-group Trial to Assess the Efficacy of Daridorexant on Nighttime Symptoms and Daytime Functioning in Adult and Elderly Participants With Insomnia Disorder
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this clinical trial is to collect more data about the effect of daridorexant in adults and elderly people with insomnia disorder. The trial aims to find out whether daridorexant can help improve: * how trial participants sleep at night, * how trial participants function the next day. Researchers will compare daridorexant to a placebo (a look-alike inactive substance that contains no active medicine) to understand which effect daridorexant has on total sleep time and next-day functioning. Enrolled participants will: * Take daridorexant 50 mg or placebo once daily for approximately 3 months * Visit the clinic once every month during treatment for checkups and tests * Keep a sleep diary of the number of hours they sleep and how well they sleep * Complete a questionnaire every day about any symptoms of sleepiness during the day and any impact on physical and mental functioning such as energy levels, mood, or ability to concentrate or memorize.
