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.

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

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  4. Outpatients
  5. Participants with a LSAS-J (Liebowitz Social Anxiety Scale Japanese version) total score of 70 or higher and a CGI-S (Clinical global impression-Severity) score of 4 or higher

    • Participants with a comorbid or past history of schizophrenia or other psychotic disorders as defined by DSM-5-TR (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision)
    • Participants with neurodevelopmental disorders, neurocognitive disorders, or personality disorders (excluding avoidant personality disorder) as defined by DSM-5-TR
  2. Participants who have been primarily diagnosed with a disorder other than social anxiety disorder according to DSM-5-TR (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision) criteria within 24 weeks prior to screening
  3. Participants with a MADRS (Montgomery Åsberg Depression Rating Scale) total score of 15 or higher
  4. Participants who, in the opinion of the principal (or sub-investigator), have not responded to at least two different SSRIs (Selective serotonin reuptake inhibitor), each administered at an adequate dose for at least 10 weeks, in treating social anxiety disorder
