NCT04086342

Brief Summary

No substantial clinical trials of Cannabidiol (CBD) in Social Anxiety Disorder (SAD) have yet been conducted. This randomized doubleblind, placebo-controlled trial of CBD in adults with SAD will evaluate the efficacy, tolerability and safety of CBD oil (CHI-902) in SAD. In addition, the effects of treatment with CHI-902 on the Endocannabinoid System (ECS) will be assessed by evaluating peripheral endocannabinoids (Arachidonoylethanolamide/Anandamide (AEA) and 2-Arachidonoyl glycerol (2-AG)) before and after treatment.

Outcome Measures

Primary Outcomes (1)

  • Liebowitz Social Anxiety Scale (LSAS)

    Quantitative change in LSAS total score from baseline to endpoint (week 10) in subjects receiving active treatment with CHI-902 compared to subjects receiving placebo. The scale is composed of 24 items divided into 2 subscales, 13 concerning performance anxiety, and 11 pertaining to social situations. The 24 items are first rated on a scale from 0 to 3 on fear felt during the situations, and then the same items are rated regarding avoidance of the situation. Combining the total scores for the Fear and Avoidance sections provides an overall score with a maximum of 144 points. Research supports a cut-off point of 30, in which SAD is unlikely. The next cut-off point is at 60, at which SAD is probable. Scores between 60 and 90 indicate that SAD is very probable. Scores higher than 90 indicate that SAD is highly probable.

    Baseline to endpoint (week 10)

Secondary Outcomes (1)

  • Systematic Assessment of Side Effects in Clinical Trials (SAFTEE)

    After 10 weeks of treatment.

Study Arms (2)

CHI-902

ACTIVE COMPARATOR

Study subjects will enter a titration phase of 1 week with a daily oral CBD dose of 150 mg (50 mg three times daily). Then, daily CBD dose of 300 mg or matching placebo will be given for 3 weeks (treatment phase 1; fixed dose).

Drug: CHI-902

Placebo

PLACEBO COMPARATOR

Study subjects will enter a titration phase of 1 week with a daily oral dose of 150 mg (50 mg three times daily) of matching placebo. Then, daily dose of 300 mg of matching placebo will be given for 3 weeks (treatment phase 1; fixed dose).

Drug: Placebo

Interventions

A standardized cannabis extract in MCT oil administered in oral liquid (oil) form.

Also known as: CBD Oil
CHI-902

Placebo is a vehicle oil that will match CHI-902.

Also known as: Placebo Oil
