Clinical Trial Summary

The primary objective of this study is to evaluate the effects of acetyl-L-carnitine (ALCAR), 3 g daily, and matched placebo on alcohol cue-elicited alcohol craving during a human laboratory paradigm after 4 weeks of daily dosing among participants ages 14-20 with alcohol use disorder (AUD) as confirmed by the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5™) and who report at least mild depressive symptoms on the Beck Depression Inventory-II. Secondary objectives include evaluation of ALCAR (3g/day) and matched placebo on alcohol craving and use, subjective effects of alcohol consumption, mood, sleep, alcohol use negative consequences, study retention, and safety and tolerability.
