ICONICplus - Randomized, Double-blind, Placebo-controlled Trial to Investigate the Effects of Cannabidiol Plus Naltrexone on Cue-Induced Alcohol Craving in Alcohol Dependence
In Brief
A Phase 2 clinical trial evaluating Cannabidiol capsules, Naltrexone (drug), and 1 other intervention for Alcohol Addiction and Alcoholism. Currently recruiting, targeting 150 participants across 2 sites.
Detailed Summary
Alcohol addiction (AD) is a chronic relapsing disorder with currently limited pharmacological treatment options. Alcohol craving, a hallmark symptom of AD that drives relapse in patients, is only insufficiently treated by existing medication. One promising new compound for the treatment of alcohol craving in AD is Cannabidiol (CBD), which showed beneficial effects on alcohol craving in preliminary clinical studies. Additionally, CBD seems to be a particularly promising candidate for enhancing the effects of established medication, specifically Naltrexone (NTX), an opioid-antagonist, which is approved for AD treatment, due to the synergistic effects of the combination of Cannabidiol plus Naltrexone on alcohol consumption that were shown by preclinical studies. The proposed three-armed, 1:1:1 randomized, double-blind, placebo-controlled parallel group, multicentric phase II trial seeks to test the putative synergistic effects of combined CBD (800mg) + oral NTX (50mg) against CBD (1200mg) + oral NTX (50mg) against Placebo + oral NTX (50mg) on alcohol craving (primary outcome) in male and female patients with AD that suffer from high alcohol craving. The trial seeks to test the effects of the innovative combination of CBD plus NTX against Placebo plus NTX on alcohol craving over a 14-day treatment period, which is embedded in a standardized addiction treatment program according to current treatment guidelines, in order to estimate the added value of treatment with CBD on alcohol craving. Quality of life and neurobiological and biochemical markers for craving will serve as secondary outcomes, because they show strong associations to treatment outcome and relapse risk. Collection and analysis of follow-up data (28 days, 42 days, 105 days, 196 days) will be performed to determine whether treatment effects relate to patient outcome.
