This U.S. conducted at multiple hospitals, where neither patients nor doctors know which treatment is given, compared against an inactive treatment Phase 2 clinical trial is designed to evaluate the effectiveness, safety, and tolerability of a repeat intranasal (i.n.) dose of Fasedienol Nasal Spray (fasedienol) (3.
View original scientific description
This U.S. multicenter, double-blind, placebo-controlled Phase 2 clinical trial is designed to evaluate the efficacy, safety, and tolerability of a repeat intranasal (i.n.) dose of Fasedienol Nasal Spray (fasedienol) (3.2 µg) to relieve symptoms of acute anxiety in adult subjects ages 18 through 65 with Social Anxiety Disorder induced by a public speaking challenge (PSC) in a clinical setting.

Interventions
DRUG
Fasedienol Nasal Spray - Placebo Nasal Spray
Twenty minutes prior to the PSC, subjects will receive one dose of Fasedienol Nasal Spray followed by one dose of Placebo Nasal Spray, separated by 10-minutes in between the two doses.
DRUG
Fasedienol Nasal Spray - Fasedienol Nasal Spray
Twenty minutes prior to the PSC, subjects will receive one dose of Fasedienol Nasal Spray followed by a second dose of Fasedienol Nasal Spray, separated by 10-minutes in between the two doses.
DRUG
Placebo Nasal Spray - Placebo Nasal Spray
Twenty minutes prior to the PSC, subjects will receive one dose of Placebo Nasal Spray followed by a second dose of Placebo Nasal Spray, separated by 10-minutes between the two doses.
Primary outcome measures
Subjective Units of Distress Scale (SUDS)
Time frame: 7 days (Visit 2 to Visit 3)
The SUDS is a patient self-rated acute measurement scale that is scored in the range of 0 to 100 (operationalized for participants in this study as 0=totally relaxed or no anxiety at all and 100=highest distress or anxiety ever felt.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
