Phase 3
Recruiting
Conditions
Social Anxiety Disorder
Interventions
Drug: 225 mg BNC210
Drug: Placebo
Registration Number
NCT06510504
Lead Sponsor
Bionomics Limited
Brief Summary

The purpose of the study is to evaluate the effect of a single, acute dose of BNC210 compared to placebo on reducing the severity of anxiety provoked by a behavioral assessment task and measured using the Subjective Units of Distress Scale (SUDS) in adult patients with social anxiety disorder.

Detailed Description

This is a randomized, double-blind, placebo-controlled, 2-arm, parallel-group, multi-center study. Participants will attend a Screening Visit to confirm eligibility and then return to the clinic within 21 days to be randomized into the study. Randomized participants will receive a single dose of their allocated study medication (225 mg BNC210 or placebo) and approximately 1 hour later participate in a behavioral assessment task. After 1 week, a safety follow-up assessment will be conducted by phone/video conference.

Primary Outcome Measures
NameTimeMethod
Subjective Units of Distress Scale (SUDS)1 day

The Subjective Units of Distress Scale (SUDS) is a self reported measure of the intensity of distress currently experienced by an individual. The range is 0-100, with a higher score indicating a higher level of anxiety/greater distress.

Secondary Outcome Measures
NameTimeMethod
Clinical Global Impressions-Severity (CGI-S)1 day

The CGI-S measures overall disease severity of the participant's symptoms as scored by a clinician. Severity is rated from 1 (normal, not at all ill) to 7 (among the most extremely ill of patients) with a higher score indicating a higher level of disease severity.

Patient Global Impressions-Improvement (PGI-I)1 day

The PGI-I is a patient self-reported counterpart of the CGI designed to assess the patient's impression of their perceived change in overall symptoms. Improvement is rated from 1 (very much improved) to 7 (very much worse) with a higher score indicating a higher level of disease severity.

State-Trait Anxiety Inventory (State Component; STAI-State)1 day

The State-Trait Anxiety Inventory (State component; STAI-State) is a self reported measure of subjective anxiety at the time of questionnaire completion. The range is 0-80 with a higher total score indicating a higher level of anxiety.
