Clinical Trial Summary

The goal of the proposed project is to begin rigorous study of the clinically relevant effects of non-psychoactive phytocannabinoid cannabidiol (CBD) in patients with severe alcohol use disorder (AUD). This double-blind, randomized proof-of-concept study (n = 40) is designed to assess feasibility and contrast effects of extended (8 weeks) treatment with CBD to those of placebo in AUD patients. Participants with AUD will be randomized to receive either placebo or 600mg CBD/day (PO) for 4 weeks, immediately followed by 1200mg CBD/day (PO) for an additional 4 weeks (8 total weeks). These doses were chosen to reproduce serum CBD levels reported to reduce alcohol-seeking behavior in animal studies. Measures will include circulating levels of CBD, safety measures (THC serum levels, adverse events, cognitive and motoric function), and physiological and psychological domains relevant to AUD (including self-reported craving, depression, and anxiety, and responses to personalized scripts designed to elicit stress- and cue-induced craving and anxiety). Assessments will be conducted following 1 day, 1 week, and 4 weeks of treatment with each dose of CBD vs. placebo, and 1 and 4 weeks after the cessation of treatment. Drinking outcomes across 8 weeks of treatment and 4 weeks of follow-up will also be assessed as an exploratory outcome.

Description:

There is increasing recognition of the roles of the endocannabinoid system in neurobiological processes and behavioral domains relevant to addiction. The non-psychoactive phytocannabinoid cannabidiol (CBD) has attracted considerable attention due to its lack of abuse potential, its excellent safety profile, its unique and complex pharmacology, and evidence that it affects anxiety and stress response in animal models and humans. There is a growing body of preclinical data demonstrating that CBD produces marked and persisting decreases in alcohol self-administration and preference for alcohol, and alcohol-, cue- and stress-induced reinstatement of alcohol-seeking behavior, yet there are few studies of the effects of CBD in humans with addictive disorders, and none in alcohol dependent patients.
