Summary

This phase 2 trial tested whether darigabat, an oral tablet, could help people with panic disorder. About 80 participants took either darigabat or a placebo for several weeks. The goal was to see if the drug could reduce panic attacks and improve overall symptoms. The study was terminated early, so results are limited.

What this could mean

What could go wrong
