Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to learn which doses of PS433540 should be given to patients with high blood pressure to lower their blood pressure. This study will also examine how safe PS433540 is when taken by patients with high blood pressure. Approximately 720 patients will be evaluated so that about 375 patients will be entered into the treatment phase of the study and be given PS433540.
