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.

Interventions

DRUGAliskiren (6.25/12.5/25 mg)

Aliskiren dispensing capsules containing minitablets (3.125 mg per minitablet). For the low dose arm, participants used one or more of the 6.25 mg capsule (containing 2 minitablets) once daily to reach the body-weight stratified dose of aliskiren.

DRUGAliskiren (37.5/75/150 mg)

Aliskiren dispensing capsules containing minitablets (3.125 mg per minitablet). For the medium dose arm, participants used one or more of the 37.5 mg capsule (containing 12 minitablets) once daily to reach the body- weight stratified dose of aliskiren.

DRUGAliskiren (150/300/600 mg)

Aliskiren dispensing capsules containing minitablets (3.125 mg per minitablet). For the high dose arm, participants used one or more of the 150 mg capsule (containing 48 minitablets) once daily to reach the body- weight stratified dose of aliskiren.

Change From Baseline in Mean Arterial Pressure (MAP) at Endpoint (Phase 1)Baseline to endpoint (Week 4 or LOCF)MAP was defined as the average arterial pressure during a single cardiac cycle. The MAP was measured as sum of diastolic blood pressure (DBP) and one third of difference between systolic blood pressure (SBP) and DBP i.e. MAP = DBP+1/3\*(SBP-DBP).

Change in Mean Sitting Diastolic Blood Pressure (msDBP) From Week 4 to Endpoint (Phase 2)

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 sDBP measurements were used as the average sitting office blood pressure for that visit.

Time frame: Week 4 to endpoint (Week 8 or LOCF)

Population: The analysis was performed on the FAS population. Here, Number of participants analyzed signifies participants evaluable for msDBP at Week 8 or LOCF for each arm, respectively.

Number of Participants With Adverse Events and Serious Adverse Events From Baseline to Week 4 (Phase 1)

Adverse events (AEs) were defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome or disease which either occurs during study, having been absent at baseline, or, if present at baseline, appears to worsen. Serious adverse events (SAEs) were defined as any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgement of investigators represent significant hazards.

Time frame: Baseline up to Week 4

Population: The analysis was performed on the Safety Sets (SAF), SAF is all participants who received at least one dose of study treatment during phase 1 (baseline to week 4)
