Primary Outcome Measures:
  • Proportion of patients who reach overall blood pressure control (defined as BP <140/90 mmHg for non-diabetic patients and < 130/80 mmHg for diabetic patients) [ Time Frame: Week 8 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline in systolic blood pressure (SBP) [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
  • Change from baseline in diastolic blood pressure (DBP) [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
  • Incidence of adverse effects [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 1080
Study Start Date: December 2009
