New hypertension drug combo enters first human tests
NCT ID NCT07312799
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial will test two experimental drugs, AD-2321 and AD-2322, in 41 healthy adults to see how they interact in the body. The study focuses on safety and how the drugs are processed, not on treating high blood pressure. Results will guide future studies in patients with hypertension.
