Alcohol Use Disorder Clinical Trial
Official title:
Cannabidiol for Reducing Drinking in Alcohol Use Disorder and Modifying the Effects of Alcohol on the Brain and the Liver: a Phase 2 Clinical Trial.-The CARAMEL Study
The non-psychotomimetic cannabis compound cannabidiol (CBD) has been found effective for reducing alcohol drinking in mice. Moreover, other experimental studies have found that CBD reduced alcohol-induced steatosis in the liver, and reduced alcohol-related injury in the brain. Despite these promising results from animal data, no human study has been conducted yet in alcohol use disorder (AUD).
CBD has several potential therapeutic prospects in AUD. Preclinical studies now support the potential of CBD for drinking reduction in AUD subjects. Moreover, other experimental studies have found that CBD reverse the alcohol-induced steatosis process in the liver. These two experimental effects need a translational confirmation in humans through an explanatory phase 2 study. In addition, CBD could also exert neuroprotective effects that reduce the deleterious effects of alcohol on the brain. In both the liver and the brain, the idiosyncratic anti-inflammatory effects of CBD could thus strengthen the overall harm reduction allowed by drinking reduction in AUD ± ALD patients. CBD deserves an exploratory study assessing whether the different therapeutic prospects in AUD are warranted. Moreover, because CBD is extracted from cannabis, and even if it is a CB1 antagonist with no psychotomimetic effects and no reported potential for abuse, the first pieces of evidence in AUD should confirm that CBD is safe in AUD subjects. The CARAMEL study is a phase-2 clinical trial on 76 subjects, which aims to investigate the efficacy of CBD on reducing alcohol drinking, as well as the potential of CBD for restraining alcohol-induced brain and liver injuries, and confirm the good safety profile of CBD. ;
