Primary Outcome Measures:

Change in mean sitting diastolic blood pressure (dBP), assessed by conventional blood pressure measurements after 12 weeks of treatment [ Time Frame: Baseline to 12 weeks ]

Secondary Outcome Measures:

Change in mean sitting diastolic blood pressure, assessed by conventional blood pressure measurements after 1, 2, 3, 8, 18, 24, 30, 36, 44 and 52 weeks of treatment; [ Time Frame: Baseline to 1, 2, 3, 8, 18, 24, 30, 36, 44 and 52 weeks ]
Change in mean sitting systolic blood pressure, assessed by conventional blood pressure measurements after 1, 2, 3, 8, 18, 24, 30, 36, 44 and 52 weeks of treatment; [ Time Frame: Baseline to 1, 2, 3, 8, 18, 24, 30, 36, 44 and 52 weeks ]
Response to treatment after 1, 2, 4, 8, 12, 18, 24, 30, 36, 44 and 52 weeks of treatment; [ Time Frame: Baseline to 1, 2, 4, 8, 12, 18, 24, 30, 36, 44 and 52 weeks ]
Response to treatment = mean sitting diastolic blood pressure less than or equal to 90 mmHg or reduction greater than or equal to 10 mmHg
Changes in creatinine clearance after 12 and 52 weeks of treatment, changes in proteinuria after 4, 12, 24, 36 and 52 weeks of treatment; [ Time Frame: Baseline to 12 and 52 weeks ]
Changes in serum creatinine after 12 and 52 weeks of treatment [ Time Frame: Baseline to 12 and 52 weeks ]
Rate of patients per dose level after 12 and 52 weeks of treatment [ Time Frame: Baseline to 12 and 52 weeks ]
Change in proteinuria after 4, 12, 24, 36 and 52 weeks of treatment [ Time Frame: Baseline to 4, 12, 24, 36 and 52 weeks ]
