The Effects of Exenatide, a GLP-1 Agonist, on Alcohol Self-Administration

Status Terminated

Clinical Trial Summary

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.

Clinical Trial Description

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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
