Een onderzoek naar Suvorexant (MK-4305) voor de behandeling van slapeloosheid bij deelnemers met een opioïdengebruiksstoornis (MK-4305-098)

17 september 2026 bijgewerkt door: Merck Sharp & Dohme LLC

Een fase 3, multicenter, gerandomiseerde, dubbelblinde, placebogecontroleerde studie om de werkzaamheid en veiligheid van Suvorexant voor de behandeling van slapeloosheid bij deelnemers met een opioïdengebruiksstoornis te evalueren

People with opioid use disorder (OUD) can have trouble falling or staying asleep. Researchers want to know if suvorexant will help people with OUD fall asleep and stay asleep. The goal of this study is to learn about the safety of suvorexant and how well people tolerate it. Researchers also want to learn if suvorexant helps people sleep longer compared to people who take placebo. A placebo looks like the study medicine but has no actual study medicine in it.
