Official title

Endocannabinoid System Engagement to Reduce Anxiety Reactivity with Cannabidiol in Social Anxiety Disorder (R61 Project)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study seeks to understand how cannabidiol (CBD) - a non-intoxicating chemical compound obtained from the Cannabis sativa plant - affects biological and stress-related responses that are believed to underlie anxiety disorders. This study will evaluate the effects of different doses of CBD on blood plasma levels of anandamide (a molecule in the brain that has been shown to help regulate stress responses; primary biological signature) and anxiety reactivity to a standardized stress task (secondary target) in an acute (4-day) dosing study (i.e., when steady state CBD levels have been reached). Approximately 60 subjects with social anxiety disorder (SAD), ages 18-70, will participate in this study. They will be assigned by chance to receive one of two doses of CBD (150 mg BID or 450 mg BID administered in two divided doses daily) or placebo (which resembles the study drug but has no active ingredients) BID for 3 days and on the morning of day 4. Knowledge gained from this study will help determine the therapeutic potential of CBD for anxiety.
