This study is about testing a medicine called lorundrostat to see if it is safe and works well for people with high blood pressure (also known as hypertension). Lorundrostat is an aldosterone synthase inhibitor, which means it helps control blood pressure by blocking a chemical in the body. The study lasts for up to 36 or 48 weeks, with an additional 2-week safety check. Participants must have been part of a previous lorundrostat study and meet specific criteria. A special part of the study will involve some people stopping the medicine to see what happens. If you complete the study, you may be invited to continue until the medicine is officially approved or the study ends early. To join, you need to be at least 18 years old, agree to use birth control if you could have children, and follow study rules. Pregnant women and those using certain medicines cannot join.

• Study lasts up to 48 weeks, plus 2-week follow-up.
