First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
