PH94B Nasal Spray for Social Anxiety Disorder
(Palisade-2 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a nasal spray called PH94B to determine its effectiveness in reducing anxiety for people with social anxiety disorder (SAD) during public speaking. Participants will use the nasal spray before facing a public speaking challenge to assess the spray's effectiveness. The trial seeks adults diagnosed with social anxiety disorder who frequently experience anxiety when speaking in front of others. As a Phase 3 trial, this study serves as the final step before potential FDA approval, providing participants an opportunity to contribute to the development of a new treatment for social anxiety disorder.
Do I need to stop taking my current medications to join the trial?
Yes, you will need to stop taking any psychotropic medications, anxiolytics (medications for anxiety), and any over-the-counter or herbal products for anxiety 30 days before joining the study and during the study.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that the PH94B nasal spray is generally safe. In earlier studies, only about 2.9% of participants stopped using the spray due to side effects like a stuffy nose or discomfort. Most other side effects were mild or moderate, such as slight irritation. Overall, most people can use the spray without problems. This information supports the safety of PH94B for treating anxiety.12345
Why do researchers think this study treatment might be promising for social anxiety disorder?
Unlike the standard treatments for anxiety, which often include oral medications like SSRIs and benzodiazepines, PH94B nasal spray offers a novel approach by acting directly through the nasal passages. This unique delivery method allows PH94B to potentially provide rapid relief from anxiety during public speaking, targeting the nasal chemosensory receptors to quickly influence brain regions involved in emotional processing. Researchers are excited because this intranasal spray could offer fast-acting anxiety relief without the systemic effects typically associated with oral medications, making it a promising option for situational anxiety.
What evidence suggests that this trial's treatments could be effective for social anxiety disorder?
Research has shown that PH94B nasal spray, which participants in this trial may receive, might help reduce anxiety symptoms related to social anxiety disorder (SAD). In a recent study, Vistagen found that the nasal spray successfully reduced anxiety during social situations. Early results suggest that the spray works quickly to calm nerves by reducing the body's stress response. This treatment is generally well-tolerated, with most people experiencing no serious side effects. Overall, PH94B appears to be a promising option for quick relief in anxiety-inducing situations like public speaking.678910
