Overview
Brief Summary
The purpose of this study is to evaluate in a randomized, double-blind fashion, the long-term safety, tolerability and efficacy profile of aliskiren compared to the active comparator enalapril in children, 6 - 17 years old with hypertension (msSBP ≥ 95th percentile for age, gender and height, at baseline in study CSPP100A2365). Patients will be randomized to receive either aliskiren or enalapril. Weight-group based doses of aliskiren or enalapril will be administered once daily and children will receive study medication in a double-blind manner. This study is being conducted to support monotherapy registration of aliskiren for the treatment of hypertension in pediatric patients 6-17 years of age (age at baseline in Study CSPP100A2365).

Arms & Interventions
Aliskiren
Patients will receive one of the following doses based on the their weight: Low weight (≥20 to \<50 kg) patients: Starting dose 37.5 mg with optional titration to 75 and then 150 mg Mid weight (≥50 to \<80 kg) patients: Starting dose 75 mg with optional titration to 150 and then 300 mg High weight (≥80 to ≤150 kg) patients: Starting dose 150 mg with optional titration to 300 and then 600 mg
Intervention: Aliskiren
Enalapril
Patients will receive one of the following doses based on their weight: Low weight (≥20 to \<50 kg) patients: Starting dose 2.5 mg with optional titration to 5 and then 10 mg Mid weight (≥50 to \<80 kg) patients: Starting dose 5 mg with optional titration to 10 and then 20 mg High weight (≥80 to ≤150 kg) patients: Starting dose 10 mg with optional titration to 20 and then 40 mg
Intervention: Enalapril
Outcomes
Primary Outcomes
Change From Baseline in Mean Sitting Systolic Blood Pressure (msSBP) at to End of Study
Time Frame: Baseline - end of study (Week 52 or Last observation carried forward (LOCF)
Sitting blood pressure was measured using a calibrated standard sphygmomanometer after the participants remained in sitting position for 5 minutes at clinic during the visit. The repeat sitting measurements were made at 2 to 3 minute intervals and the mean of three sSBP measurements were used as the average sitting office blood pressure for that visit.
Secondary Outcomes
- Change in Mean Sitting Diastolic Blood Pressure (msDBP) From Baseline to End of Study(Baseline - end of study (Week 52 or Last observation carried forward (LOCF))
- Change in Mean Arterial Pressure (MAP) (mmHg) From Baseline to End of Study(Baseline to end of study (Week 52 or LOCF))
