ClinConnect Summary

This clinical trial is studying a new treatment called SEP-363856 to see how well it works and how safe it is for adults with Generalized Anxiety Disorder (GAD). GAD is a condition where people feel excessive worry or anxiety about various aspects of life. The trial is open to both men and women aged 18 to 65 who have been diagnosed with GAD. Participants will need to be willing to follow the study’s procedures and attend scheduled visits.

If you join the study, you could be involved for about 12 weeks. While the trial is taking place at around 50 centers worldwide, there will also be additional locations specifically in Japan. It's important to note that individuals with certain other mental health conditions, those who have not responded to multiple antidepressant treatments, or those with significant medical issues may not be eligible to participate. This study aims to provide valuable information about a potential new option for treating GAD, so your participation could help advance understanding and treatment of this condition.
