Summary
This early-stage study tests a new drug called HJB647 in Japanese adults with elevated blood pressure or mild-to-moderate hypertension. The main goal is to check safety and how the drug moves through the body. About 74 participants will receive either HJB647 or a placebo, with doses given once or multiple times.
