(sDBP) ≦ 180/110 mmHg at screening visit.
- For non-diabetic patient, sitting systolic blood pressure (sSBP) ≧ 140 mmHg or
sitting diastolic blood pressure (sDBP) ≧ 90 mmHg at baseline visit; for diabetic

informed consent form.
Exclusion Criteria:

accident within the preceding 6 months, clinically significant valvular heart
disease, or hepatic and/or renal dysfunction as defined by the following laboratory
parameters
