This study is looking at a new medicine called QCZ484, given as a shot under the skin every 6 months, to help people with mild to moderate high blood pressure (also called hypertension). They want to see if it's safe and if it works well compared to a placebo, which is like a pretend medicine. In this study, people will get different amounts of QCZ484 or the placebo, and no one will know which one they are getting to make the test fair.

Key Points to Consider:

• This study lasts for 6 months, with regular visits to the study center.
• Participants may need to stop their current blood pressure medicine for up to 4 weeks before starting the study.
• The study is for adults aged 18 to 75 with mild to moderate high blood pressure.

To join, you should not have other health problems like liver disease or heart issues and should not have had a stroke or heart attack recently. You should also not be allergic to certain blood pressure medicines.
