Fasedienol Nasal Spray for Social Anxiety Disorder

This study is testing Fasedienol Nasal Spray to see if it can quickly reduce anxiety in adults with social anxiety disorder. You might receive Fasedienol Nasal Spray or a placebo (an inactive spray) before a public speaking challenge. Researchers will measure your anxiety using a scale called the Subjective Units of Distress Scale (SUDS) to see if the treatment works. The study is also looking at how safe and well-tolerated Fasedienol Nasal Spray is. You can join if you are between 18 and 65 years old and have a diagnosis of social anxiety disorder. The study status is currently unclear.

Study design
This is a multicenter, double-blind, placebo-controlled clinical trial, meaning neither you nor your doctor will know if you are receiving Fasedienol Nasal Spray or placebo. It plans to enroll 60 participants.
What's involved
Twenty minutes before a public speaking challenge, you will receive two doses of nasal spray, separated by 10 minutes. Your anxiety will be measured at 7 days (between Visit 2 and Visit 3).
Compensation
Not stated in the trial record.
Follow-up
Your anxiety levels will be measured for 7 days after the treatment. There is also an optional open-label extension phase that could last up to 12 months.
