Primary Outcome Measures:
  • Change from baseline in Mean Sitting Diastolic Blood Pressure (MSDBP) [ Time Frame: Baseline, Week 8 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline in MSDBP [ Time Frame: Baseline, week 4 ] [ Designated as safety issue: No ]
  • Change from baseline Mean Seated Systolic Blood Pressure (MSSBP) [ Time Frame: Baseline, Week 4 and 8 ] [ Designated as safety issue: No ]
  • Blood pressure responder rate [ Time Frame: Baseline, Week 4 and 8 ] [ Designated as safety issue: No ]
    Rate of patients who achieved target blood pressure (MSSBP < 140 mmHg and MSDBP < 90 mmHg), or MSSBP decrease > 20 mmHg from baseline or MSDBP decrease > 10 mmHg from baseline.
