简要总结
The goal of this clinical trial is to learn about how certain medications used to treat insomnia (e.g., Lemborexant) impact sleep, mood, and behavior in men and women with Opioid Use Disorder who are taking prescribed buprenorphine. The main questions it aims to answer are:
- What is the effect of the study drug (lemborexant) on sleep outcomes?
- What is the effect of the study drug (lemborexant) on impulsive behavior (as measured by computer test performance)?
- What is the effect of the study drug (lemborexant) on mood and other behavior?
Researchers will compare lemborexant to placebo (e.g., sugar pill) to see if participants assigned to 8 weeks of treatment with lemborexant have greater improvements on the measures listed above.
Participants will take the study medication (or placebo) each night for 8 weeks and be asked to come for a total of 23 study visits. Most of these visits will be very short (15-30 minutes). The longer visits will include the screening visit (about 2-3 hrs), baseline visit (about 2.5 hrs), and the post-medication visit (about 2 hrs). Study visits will include things like taking surveys about sleep, drug use, and mood, completing urine drug testing, checking vital signs (e.g., blood pressure), and completing interviews with the study staff. Participants will also be asked to provide two blood samples (one during screening and one after taking the medication). For three two-week periods, participants will be asked to wear a watch to track sleep at home, and to keep a log of sleep and wake times.

结局指标
主要结局
Insomnia
时间窗: from 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.
Impulsivity
时间窗: from 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.
