Trial Outcomes & Findings for A Study to Evaluate the Safety/Tolerability and Pharmacokinetics of Aliskiren in Hypertensive Pediatric and Adolescent Patients 6-17 Years of Age (NCT NCT00834041)

NCT ID: NCT00834041

Last Updated: 2011-05-09

Results Overview

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 outcome

Timeframe: Baseline to end of treatment (Day 9)

Population: Full Analysis Set (FAS): All randomized patients, excluding mis-randomized patients.

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.
