Une étude sur le suvorexant (MK-4305) pour le traitement de l'insomnie chez les participants souffrant de troubles liés à l'usage d'opioïdes (MK-4305-098)

17 septembre 2026 mis à jour par: Merck Sharp & Dohme LLC

Une étude de phase 3, multicentrique, randomisée, en double aveugle et contrôlée par placebo pour évaluer l'efficacité et l'innocuité du suvorexant pour le traitement de l'insomnie chez les participants souffrant de troubles liés à l'usage d'opioïdes

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.
