August 14, 2026 updated by: Vanda Pharmaceuticals

A Phase III, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of VQW-765 for the On-Demand Treatment of Acute Anxiety in Patients With Social Anxiety Disorder

This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of a single oral dose of VQW-765 compared to placebo in adults with social anxiety disorder.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will enroll approximately 500 patients with current diagnosis of social anxiety disorder (SAD). Eligible participants will be randomly assigned to receive either a single oral dose of VQW-765 or placebo in a 1:1 ratio, followed by a psychosocial stress test. 1-2 weeks after the treatment visit, a safety follow-up assessment will be conducted remotely.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Subjective Units of Distress Scale (SUDS)
Time Frame: 1 day
Subjective Units of Distress Scale (SUDS) during performance phase, scored from 0-100 with a higher score indicating higher distress.
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Subjective Units of Distress Scale (SUDS)
Time Frame: 1 day
Subjective Units of Distress Scale (SUDS) during anticipation phase, scored from 0-100 with a higher score indicating higher distress.
1 day
State-Trait Anxiety Inventory - State Anxiety Scale (STAI-S)
Time Frame: 1 day
State-Trait Anxiety Inventory - State Anxiety Scale (STAI-S), scored from 20 to 80 with higher scores indicating higher anxiety level.
1 day
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
