NCT ID NCT06483789
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tests a new drug called HB-1, which combines two blood pressure medicines (telmisartan and verapamil), to see if it can reduce unexpected panic attacks in people with panic disorder. The study plans to enroll 240 adults aged 18 to 65 and compare HB-1 against placebo and each drug alone. However, the trial is currently suspended, so results are on hold.
