A double-blind, randomized, placebo-controlled, crossover design trial was used to test the effect of exenatide on alcohol self-administration and craving following a priming dose of alcohol. The specific objective of this research was to determine whether exenatide has effects on alcohol consumption.
This proposal was intended to answer the call for accelerating drug development by exploring the potential of a glucagon-like peptide-1 (GLP-1) agonist, exenatide, as a candidate medication for the treatment of Alcohol Use Disorder. There is now substantial preclinical evidence that GLP-1 agonists can attenuate behaviors that model both the consumption and seeking of several commonly abused substances including alcohol, cocaine, and nicotine. This study was intended to accelerate medication development for Alcohol Use Disorder by testing a commercially-available and well-tolerated agent at a fraction of the cost of new drug discovery. None of the FDA-approved Alcohol Use Disorder medications or off-label Alcohol Use Disorder medications target this GLP-1 pathway, making exenatide a promising compound for Alcohol Use Disorder drug development.
The primary aim of this study was to test the effects of exenatide on alcohol self-administration and craving among heavy drinkers. In this within-subjects crossover design, 3 heavy drinkers were randomized to exposure order (exenatide or sham injection) prior to completing two alcohol self-administration trials. Subjects received a priming drink of alcohol and had access to 8 drinks over a 2-hour period. The investigators anticipated that subjects would consume less alcohol following the administration of exenatide compared to when they received a sham injection. Significant exenatide-induced reductions in drinking would be considered to be an indication that this drug may have value as an Alcohol Use Disorder medication. This study may provide a rationale for phase II randomized controlled trials testing exenatide with a treatment-seeking Alcohol Use Disorder population. These results may also help to spur further clinical investigation of the effects of exenatide and other available GLP-1 agonists on the factors implicated in the regulation of alcohol consumption.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

This is a within subjects design study in which each subject receives both study drug and placebo. Subjects in this arm received a 5 mcg dose of immediate release exenatide on the day of the first alcohol self-administration trial. The 5mcg dose of exenatide was approved as the first dose administered to patients at the start of their treatment with this drug for FDA-approved indications. Subjects in this arm then received a sham injection on the day of the second alcohol self-administration trial. The sham injection was a needle stick using a syringe with no drug injected. Note that the volume of fluid injected for a 5mcg dose is so small that subjects would not sense this volume of fluid (or lack thereof) during the injection. Subjects were shielded from seeing the injection to maintain the blind.

Alcohol Consumption
Alcohol consumption was measured by using a graduated cylinder to determine the amount of alcohol given to the subject that was not consumed. The amount not consumed was then subtracted from the total amount of alcohol served to the subject in order to calculate the amount consumed. This outcome was measured in standard drink units (SDUs). A standard drink contains approximately 0.6 fluid ounces of pure alcohol.
