Summary

The purpose of this trial is to examine the preliminary clinical efficacy of CYB004 participants with GAD.

What are the potential side effects?
While the side effects are being studied as part of this trial's purpose, potential risks may include typical psychedelic-related effects such as sensory alterations and psychological distress. The exact profile will be clearer after the study.
