Brief summary

This is a double-blind, randomized, placebo-controlled, crossover design trial that will test the effect of pitolisant on alcohol self-administration and craving following a priming dose of alcohol. The specific objective of this proposal is to determine whether pitolisant has effects on alcohol consumption and craving

Detailed description

The present proposal is intended to answer the call for accelerating drug development by exploring the potential of a novel anticonvulsant, Pitolisant as a candidate medication for the treatment of AUD. Pitolisant is an H-3 receptor inverse agonist that is FDA-approved for treating narcolepsy which has been found to have effects of on alcohol craving and consumption in preclinical studies. The aims of this study are to test the effects of Pitolisant on alcohol self-administration and craving among a sample of non-treatment seeking heavy drinkers. The effects of 5-days of pitolisant (8.9mg) or placebo will be evaluated in a human laboratory using an alcohol self-administration methodology. In this within-subjects crossover design, heavy drinkers (N=28) will be randomized to the order of exposure (Pitolisant or placebo) prior to completing two alcohol self-administration trials. Subjects will receive a priming drink of alcohol and will have access to 8 alcoholic drinks over a 2-hour period. The investigators anticipate that subjects will consume less alcohol during an alcohol self-administration trial when receiving Pitolisant compared to when they are receiving placebo. Significant Pitolisant-induced reductions in the quantity of alcohol self-administered will be considered to be an indication that this drug may have value as an AUD medication. This study may provide a rationale for phase II clinical studies testing Pitolisant with a treatment-seeking AUD population.

Alcohol Consumption in Alcohol Self-Administration Trials

Alcohol consumption will be measured by using a graduated cylinder to determine the amount of alcohol given to the subject that was not consumed. This outcome will be measured as standard drink units (SDU). A standard drink contains approximately 0.6 fluid ounces of pure alcohol. Lower SDUs are favorable.

The minimum AUQ score is 8 and the maximum score is 56. Lower AUQ scores are associated with less urge for an alcoholic drink, and therefore more favorable.

Alcohol Urge: Self-administration Block 2, Minute 60

The Alcohol Urge questionnaire (AUQ) is an 8 item measure of self-reported urges to drink in human laboratory studies that assesses the participant's urge for an alcoholic drink at the time the questionnaire is completed, Questions are in the form of a 7-point Likert scale (from strongly disagree to strongly agree) and participants select the extent to which they disagree or agree with the 8 statements relating to desire to drink, expectation of a desired outcome from drinking, and inability to avoid drinking if alcohol was available. The minimum AUQ score is 8 and the maximum score is 56. Lower AUQ scores are associated with less urge for an alcoholic drink, and therefore more favorable.
