E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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 |
|
E.2.2 | Secondary objectives of the trial |
- 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.

|
E.4 | Principal exclusion criteria |
(For full list, please see protocol) - Pregnant or nursing (lactating) women, - Women of child-bearing potential (WOCBP) - Severe hypertension (msDBP ≥ 110 mmHg and/or msSBP ≥ 180 mmHg). - History or evidence of a secondary form of hypertension. - Known Keith-Wagener grade III or IV hypertensive retinopathy. - Previous or current diagnosis of heart failure. - History of hypertensive encephalopathy or cerebrovascular accident, transient ischemic cerebral attack (TIA), myocardial infarction, coronary bypass surgery, or any percutaneous coronary intervention (PCI). - Serum potassium < 3.5 mEq/L (mmol/L) or ≥ 5.3 mEq/L (mmol/L), serum sodium less than the lower limit of normal or dehydration. - Patients with Type 1 or Type 2 diabetes mellitus who are not well controlled based - on the investigator’s clinical judgment. Patients with diabetes mellitus enrolled in this study should be well controlled. It is recommended that patients currently being treated for diabetes mellitus be on a stable dose of oral antidiabetic medication for at least 4 weeks prior to Visit 1. - Current angina pectoris requiring pharmacological therapy. - Second or third degree heart block without a pacemaker. - Atrial fibrillation or atrial flutter at Visit 1, or potentially life threatening or any symptomatic arrhythmia during the 12 months prior to Visit 1. - Clinically significant valvular heart disease. - Any medication, surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of study drugs including, but not limited to, any of the following: - History of major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, or bowel resection. - History of active inflammatory bowel disease during the 12 months prior to Visit 1. - Currently active gastritis, duodenal or gastric ulcers, or history of gastrointestinal bleeding during the 3 months prior to Visit 1. - Evidence of hepatic disease as determined by any one of the following: ALT or AST values exceeding 3 x ULN at Visit 1, a history of hepatic encephalopathy, a history of esophageal varices, or a history of portocaval shunt. - Evidence of renal impairment as determined by any one of the following: serum creatinine > 1.5 x ULN at Visit 1, a history of dialysis, or a history of nephrotic syndrome. - Current treatment with cholestyramine and colestipol resins. - History of hypersensitivity to any of the study drugs or to drugs belonging to the similar therapeutic class (ARB’s, ACE-I’s, thiazide diuretics, or other sulfonamide derived drugs) as the study drugs. - History of angioedema due to usage of an ACE-I or ARB. - History of malignancy of any organ system, treated or untreated, within the past 5 years whether or not there is evidence of local recurrence or metastases, with the exception of localized basal cell carcinoma of the skin. - History of gouty arthritis - History or evidence of drug or alcohol abuse within the last 12 months. - Any surgical or medical condition, which in the opinion of the investigator, may place the patient at higher risk from his/her participation in the study, or is likely to prevent the patient from complying with the requirements of the study or completing the study. - Patients who previously participated in a clinical trial that contained the treatment combination of aliskiren/HCTZ and qualified to be randomized or enrolled in the active drug treatment period. - Use of other investigational drugs at the time of enrollment, or within 30 days or 5 half-lives of enrollment, whichever is longer. - History of noncompliance to medical regimens or unwillingness to comply with the study protocol. - Any condition that in the opinion of the investigator or the Novartis Medical Monitor would confound the evaluation and interpretation of efficacy and/or safety data. - Persons directly involved in the execution of this protocol. |

E.5 End points |
E.5.1 | 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. |
