Lemborexant for Insomnia in Opioid Use Disorder

This study is looking at how lemborexant, a medication for insomnia (trouble sleeping), affects sleep, mood, and behavior in people with Opioid Use Disorder (OUD). Participants must be at least 18 years old, have moderate to severe OUD, and be currently taking buprenorphine for their OUD. The study aims to see if lemborexant improves sleep, reduces impulsive behavior (acting without thinking), and positively impacts mood compared to a placebo (an inactive pill). Researchers will compare these effects over an 8-week treatment period. The current status of this study is unclear, and it plans to enroll 100 participants.

  • Insomniafrom baseline to end of 8-week treatment

    Insomnia Severity Index will be used for assessing insomnia related symptoms. Scores on this measure range from 0-28, with higher scores indicating greater symptoms. Mean ISI score per group at baseline and at the end of 8-week treatment will be reported.

  • Impulsivityfrom baseline to end of 8-week treatment

    Impulsive responding will be measured by performance on the 5-trial adjusting delay discounting task, with the outcome being a derived discounting rate. Mean delay discounting rate per group at baseline and at the end of 8-week treatment will be reported.
