Summary

This is an early-Phase II human laboratory trial using a randomized, placebo-controlled, dose-ranging design to investigate the effects of semaglutide, a GLP-1 receptor agonist, on alcohol-related outcomes in adults with alcohol use disorder (AUD).

Eligibility Criteria

Inclusion Criteria

  • Age 21-65
  • Meeting DSM-5 criteria for current (past year) alcohol use disorder (with 2-7 symptoms endorsed) and National Institute on Alcohol Abuse and Alcoholism (NIAAA) criteria for current at-risk drinking (i.e., >7/14 drinks in one week for women/men, with at least two episodes of 4+/5+ drinks in the past 30 days)
  • Willingness/availability to take study medication and complete study procedures, including attending weekly visits for medication administration, side effect assessments, and glucose monitoring
  • Willingness to complete laboratory sessions involving alcohol administration
  • Ability to communicate and read in English

Exclusion Criteria

  • Reporting past 30-day use of illicit drugs other than cannabis at baseline, or having a positive toxicology screen for illicit drugs other than cannabis at baseline
  • Meeting past-year criteria for a substance use disorder (with the exception of alcohol, tobacco or mild cannabis use disorder)
  • Current engagement in alcohol treatments, or currently engaged in intentional efforts to quit alcohol use
  • Past 30-day use of: Sincalide, Sulfonylureas, insulin and insulin products or other medications that may interact with semaglutide;, or weight control medications
  • Prior use of semaglutide or other GLP-1 agonists
  • Known or suspected hypersensitivity to study medication or related products
  • Lifetime diagnosis of severe mental illness (including schizophrenia and bipolar disorder)
  • History of suicide attempt, or recent (past 30 day) suicidal ideation, or psychiatric hospitalization in the last 6 months
  • Current significant medical or neurological illness (based on self-report or medical record) including severe hepatic impairment or cirrhosis, impaired renal function (eGFR 6.5% measured at screening
  • History of diabetic retinopathy, proliferative retinopathy, or maculopathy
  • History of diabetic ketoacidosis
  • History or presence of malignant neoplasms within the last 5 years (except basal and squamous cell skin cancer and carcinoma in situ)
  • Currently nursing, pregnant, anticipating pregnancy in the next 6 months, or not using a highly effective contraceptive method as judged by the MD, and defined as:
  • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal)
  • progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable)
  • intrauterine device
  • intrauterine hormone-releasing system
  • bilateral tubal occlusion
  • vasectomized partner
  • sexual abstinence
  • Elevation of serum lipase, amylase, direct (conjugated) bilirubin, or alkaline phosphatase (ALP), ALT, or AST) more than 3X the upper limit of normal on baseline bloodwork
  • Baseline body mass index (BMI) 180 mmHg and/or diastolic BP >105 mmHg, averaged from three measurements
  • Plans for travel outside of the local area in the upcoming 12 weeks that would interfere with lab visits during the study period (or other logistic factors that would make it difficult to commit to entire duration of study)
