Overview
Brief Summary
This double-blind 8 week study will evaluate dose response, efficacy (blood pressure lowering effect) and safety of aliskiren in children 6 - 17 years old with hypertension at low, mid and high weight-based doses. The low dose ranges from 6.25 mg to 25 mg of aliskiren, the mid dose ranges from 37.5 mg to 150 mg of aliskiren and the high dose ranges from 150 mg to 600 mg of aliskiren. This study is being conducted to support monotherapy registration of aliskiren for the treatment of hypertension in children 6-17 years of age.

Exclusion Criteria
- •Patient receiving immunosuppressant medication (e.g. cyclosporine, MMF, etc) other than oral/topical steroids, for any medical condition

Arms & Interventions
Low Dose Aliskiren
Participants received body-weight stratified dose of aliskiren capsules (6.25/12.5/25 mg) once daily. Participants whose body weight ≥ 20 kilogram (kg) to less than \< 50 kg received 6.25 mg; ≥50 kg and \< 80 kg received 12.5 mg and ≥ 80 kg and ≤ 150 kg received 25 mg of aliskiren.
Intervention: Aliskiren (6.25/12.5/25 mg)
Mid dose
Participants received body-weight stratified dose of aliskiren capsules (37.5/75/150 mg) once daily. Participants whose body weight ≥ 20 kg to \< 50 kg received 37.5 mg; ≥50 kg and \< 80 kg received 75 mg and ≥ 80 kg and ≤ 150 kg received 150 mg of aliskiren.
Intervention: Aliskiren (37.5/75/150 mg)
High dose
Participants received body-weight stratified dose of aliskiren capsules (150/300/600 mg) once daily. Participants whose body weight ≥ 20 kg to \< 50 kg received 150 mg; ≥50 kg and \< 80 kg received 300 mg and ≥ 80 kg and ≤ 150 kg received 600 mg of aliskiren.
Intervention: Aliskiren (150/300/600 mg)
Outcomes
Primary Outcomes
Change From Baseline in Mean Sitting Systolic Blood Pressure (msSBP) at Endpoint (Phase 1)
Time Frame: Baseline to endpoint (Week 4 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 1-2 minute intervals and the mean of three sSBP measurements were used as the average sitting office blood pressure for that visit.
Change in Mean Sitting Systolic Blood Pressure (msSBP) From Week 4 to Endpoint (Phase 2)
Time Frame: Week 4 to endpoint (Week 8 or 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 1-2 minute intervals and the mean of three sSBP measurements were used as the average sitting office blood pressure for that visit.
Secondary Outcomes
- Number of Participants With Adverse Events and Serious Adverse Events From Baseline to Week 4 (Phase 1)(Baseline up to Week 4)
- Number of Participants With Adverse Events and Serious Adverse Events From Week 4 to Week 8 (Phase 2)(From Week 4 to Week 8)
- Change From Baseline in Mean Sitting Diastolic Blood Pressure (msDBP) at Endpoint (Phase 1)(Baseline to endpoint (Week 4 or LOCF))
- Change in Mean Sitting Diastolic Blood Pressure (msDBP) From Week 4 to Endpoint (Phase 2)(Week 4 to endpoint (Week 8 or LOCF))
- Change From Baseline in Mean Arterial Pressure (MAP) at Endpoint (Phase 1)(Baseline to endpoint (Week 4 or LOCF))
- Change in Mean Arterial Pressure (MAP) From Week 4 to Endpoint (Phase 2)(Week 4 to endpoint (Week 8 or LOCF))
- Percentage of Participants Achieving a Positive Treatment Response at Endpoint (Phase 1)(Baseline to endpoint (Week 4 or LOCF))
- Change From Baseline in Mean Ambulatory Systolic and Diastolic Blood Pressure (MASBP and MADBP) at Endpoint (Phase 1)(Baseline to endpoint (Week 4 or LOCF))
- Change From Baseline in Mean Ambulatory Systolic Blood Pressure (MASBP) During Day and Night at Week 4 (Phase 1)(Baseline to Week 4)
- Change From Baseline in Mean Ambulatory Blood Pressure (MABP) in Dipper Participants at Endpoint (Phase 1)(Baseline to endpoint (Week 4 or LOCF))
- Change From Baseline in Mean Ambulatory Blood Pressure (MABP) in Non--Dipper Participants at Endpoint (Phase 1)(Baseline to endpoint (Week 4 or LOCF))
