简要总结
The goal of this clinical trial is to learn if Caplyta works to treat Social Anxiety Disorder in adults. The main question it aims to answer is:
Does Caplyta lower the frequency/severity of social anxiety symptoms in adults?
Researchers will compare Caplyta to a placebo (a look-alike substance that contains no drug) to see if Caplyta works to treat Social Anxiety Disorder.
Participants will:
Take Caplyta or a placebo every day for 8 weeks Visit the clinic once every week for checkups and tests

- •Diagnosis of Social Anxiety Disorder (SAD) according to DSM-5 criteria, as determined by psychiatric evaluation with the Investigator and as confirmed by the MINI at Screening.
- •Minimum total score of 70 on the LSAS at Screening and Baseline visits.
- •Total Hamilton Depression Rating Scale (HAM-D) score of less than 16 at Screening and Baseline.
- •Clinical Global Impression of Severity (CGI-S) score of 4 or greater at Screening and Baseline.
- •All subjects of childbearing potential must commit to an effective form of contraception for the duration of the trial and for at least 4 weeks after it ends.

- •Subjects who started psychotherapy or Cognitive Behavioral Therapy (CBT) within 24 weeks of Screening, except for supportive psychotherapy.
- •Subjects who have been receiving psychotherapy or CBT for more than 24 weeks prior to Screening are eligible for the study, provided that the therapy continues at the same frequency for the duration of the trial.
- •Subjects who have received any electroconvulsive therapy (ECT) within 12 weeks of Baseline.
- •Subjects who are currently pregnant, lactating, or of childbearing potential and not able and willing to practice an effective method of contraception for the duration of the trial and at least 4 weeks after the final study visit.

LSAS scores range from 0 (no anxiety) to 144 (very severe social anxiety). The LSAS consists of 24 items, each representing a different performance or social situation. Each item/situation is scored for fear/anxiety and for avoidance, each on a scale of 0 to 3, with 0 representing no anxiety/avoidance, and 3 representing severe anxiety/avoidance.
