Open Actively Recruiting

A Novel Human Lab Model for Screening AUD Medications

About

Brief Summary

This study design consists of a randomized, double-blind, placebo-controlled, 3-arm, parallel-group study of naltrexone (50 mg QD) and varenicline (1 mg BID). A total of 108 men and women with current AUD (moderate or severe) and reporting intrinsic motivation to change their drinking, will be randomly assigned to receive naltrexone (50 mg QD), varenicline (1 mg BID) or matched placebo. Post-randomization, all participants will complete an alcohol cue-reactivity paradigm prior to the initial dose of study medication. After a week-long medication titration period, participants will be asked to complete a 7-day practice quit attempt, during which they will have daily virtual visits (phone and online) where they will report on their alcohol use. Additionally, a second cue-reactivity paradigm will be conducted 90 minutes following study drug administration on final day of the practice quit attempt (Day 14).
