Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the effects of an acute dose of BNC210 compared to placebo on reducing anxiety provoked by a speaking challenge and measured using the Subjective Units of Distress Scale (SUDS) in patients with Social Anxiety Disorder (SAD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized, double-blind, placebo-controlled, 3-arm, parallel-group, multi-center study. Participants will attend a Screening Visit to confirm eligibility and then return to the clinic within 14 days to be randomized into the study. Randomized participants will receive a single dose of their allocated study intervention (225 mg BNC210, 675 mg BNC210 or placebo) and approximately 1 hour later participate in a speaking challenge. After 1 week, a safety follow-up assessment will be conducted by phone/video conference.
