Treatment and study plan

Aliskiren 3.125 mini-tablets

Drug

Oral mini-tablets (3.125 mg) of aliskiren once each morning

Primary outcomes

  1. Maximum Plasma Concentration (Cmax) at Day 1 and Day 8 in 6-11 and 12-17 Year Old Patients

    Time frame: Day 1 and Day 8

    Blood samples (1 mL) for pharmacokinetic (PK) evaluation were drawn pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 6, 10, and 24 hours following administration of aliskiren on Day 1 and Day 8. The pre-dose PK evaluations were collected in a fasted state (7-12 hours without food or beverage except water). PK parameters were calculated from plasma concentration-time data and actual recorded sampling times for each patient, using non-compartmental methods with the software program WinNonlin Pro v5.2.

  2. Area Under the Plasma Concentration-time Curve (AUC0-τ) in One Dosing Interval (24 h) at Day 1 and Day 8 in 6-11 and 12-17 Year Old Patients

    Time frame: Day 1 and Day 8

    Blood samples (1 mL) for pharmacokinetic (PK) evaluation were drawn pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 6, 10, and 24 hours following administration of aliskiren on Day 1 and Day 8. The pre-dose PK evaluations were collected in a fasted state (7-12 hours without food or beverage except water). PK parameters were calculated from plasma concentration-time data and actual recorded sampling times for each patient, using non-compartmental methods with the software program WinNonlin Pro v5.2.

  3. Apparent Plasma Clearance (CL/F) at Day 8 in 6-11 and 12-17 Year Old Patients

    Time frame: Day 8

    Blood samples (1 mL) for pharmacokinetic (PK) evaluation were drawn pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 6, 10, and 24 hours following administration of aliskiren on Day 1 and Day 8. The pre-dose PK evaluations were collected in a fasted state (7-12 hours without food or beverage except water). PK parameters were calculated from plasma concentration-time data and actual recorded sampling times for each patient, using non-compartmental methods with the software program WinNonlin Pro v5.2.

Secondary outcomes

  1. Change in Plasma Renin Activity From Baseline on Day 1, Day 8, and Day 9

    Time frame: Baseline to 2 and 10 hours post-dose on Day 1; pre-dose, 2, 10, and 24 hours post-dose on Day 8-9

    Blood samples (2 mL) for pharmacodynamics evaluation of plasma renin activity were drawn pre-dose and at 2 and 10 hours following the dose of study medication on Day 1 and at pre-dose and at 2, 10, and 24 hours post-dose on Day 8-9.

  2. Change in Mean Sitting Systolic and Diastolic Blood Pressure (msSBP and msDBP) From Baseline to the End of Treatment (Day 9) in 6-11 and 12-17 Year Old Patients

    Time frame: Baseline to end of treatment (Day 9)

    Blood pressure (BP) measurements were made with a mercury sphygmomanometer or an automated blood pressure measuring device. Sitting BP was measured 3 times at 2-3 minute intervals after the patient had been sitting for 5 minutes. Means of the 3 measurements were calculated. A negative change in BP indicates lowered BP.
