Changes in pipeline

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.

This study will evaluate efficacy, therapeutic effects, tolerability and safety of CBD oil in adults with SAD through a randomized placebo-controlled study design and will evaluate effects of CHI-902 on peripheral endocannabinoids (AEA and 2-AG). This study will be the first randomized, double-blind placebo-controlled trial conducted with CHI-902 in adults with SAD.

The study is designed to:

• Evaluate the efficacy of CHI-902 versus placebo in adults with SAD.
• Evaluate the tolerability and safety versus placebo of CHI-902 in adults with SAD.
• Explore the effects of CHI-902 versus placebo on different biomarkers in subjects with SAD.

Inclusion Criteria: Adult males or females (≥18 years of age) will be enrolled until the required number of n=160 subjects completing all study procedures is met. Individuals will be included if they:

1. Meet DSM-5 criteria for SAD
2. Score >60 on the Liebowitz Social Anxiety Scale (LSAS)

Exclusion Criteria:

2. Past or current neurological illness or head trauma;
3. History of bipolar disorder, psychotic disorder/schizophrenia, schizoaffective disorder, obsessive-compulsive disorder, or personality disorder (Cluster A or B);
4. Current moderate or severe major depressive episode, panic disorder, generalized anxiety disorder, or post-traumatic stress disorder (PTSD). Traits associated with these disorders are permissible but full DSM criteria should not be met;

12. Pregnancy or lactation;
13. Males and females of child-bearing potential must be using and willing to continue using medically acceptable contraception throughout the study to avoid pregnancy during the study and for up to 4 weeks after study completion, as described below. Study-acceptable methods of birth control are double-barrier methods, which include a combination of any 2 of the following: oral contraceptives, diaphragm, condom, copper intrauterine device, sponge, spermicide, or (partner's) vasectomy;
14. Positive urine during drug screening for drugs of abuse (except benzodiazepines);
15. Reported history of difficulty with intravenous blood draws;
