This study is testing a medicine called darigabat to see if it helps people with panic disorder. Panic disorder is when someone has sudden, intense fear that can make their heart race or make them feel like they can't breathe. The medicine will be compared to a placebo, which is a pill with no medicine in it, to see if it really works. Participants must have had at least 8 panic attacks in the month before the study and meet other health requirements. However, those with other serious mental or physical health issues, or those at risk for suicide, cannot join. Participants will take 25 mg of darigabat twice a day.

• The study checks if darigabat helps with panic attacks and if it is safe.
• Participants need to meet certain health criteria and have had recent panic attacks.
• Some people cannot join, like those with major health issues or high risk of suicide.
