| Main Objective: Demonstrate the efficacy of the combination therapy of aliskiren (150 mg and 300 mg) and HCTZ 25 mg in hypertensive patients who do not show sufficient blood pressure response to a 4-week treatment of HCTZ 25 mg by testing the hypothesis of superior reduction in mean sitting diastolic blood pressure (msDBP) from baseline to end of study when compared to HCTZ 25 mg monotherapy;Secondary Objective: - Evaluate the efficacy of the combination therapy of aliskiren (150 mg and 300 mg) and HCTZ 25 mg in hypertensive patients who do not show sufficient blood pressure response to a 4-week treatment of HCTZ 25 mg by testing the hypothesis of superior reduction in mean sitting systolic blood pressure (msSBP) from baseline to end of study when compared to HCTZ 25 mg monotherapy. - Evaluate the safety and tolerability of the combination of aliskiren (150 mg and 300mg) and HCTZ 25 mg compared with HCTZ 25 mg monotherapy in hypertensive patients who do not show sufficient blood pressure response to a 4-week treatment of HCTZ 25 mg. - Evaluate the proportion of patients achieving a blood pressure control target of < 140/90 mmHg at the end of study for all treatments arms. ;Primary end point(s): The primary efficacy variable is change from baseline (Visit 5) in mean sitting diastolic blood pressure. For each patient, the last post-baseline measurement during the double-blind period will be carried forward to Week 8 as the endpoint measurement for the variable to be analyzed. The primary analysis timepoint will be the endpoint. | — |
