Trial Outcomes & Findings for Efficacy and Safety of Once Daily Dosing of Aliskiren (300 mg (qd) Once a Day) to Twice Daily Dosing of Aliskiren (150 mg (Bid) Twice a Day) in Treating Moderate Hypertension. (NCT NCT00654875)

NCT ID: NCT00654875

Last Updated: 2011-06-28

Results Overview

An Ambulatory Blood Pressure Monitoring (ABPM) device was attached to the non-dominant arm of the participant. The mean of Blood Pressure readings during the 24 hour period were calculated. The difference of the 24 hour MADBP from baseline to the 24 hour MADBP at 6 weeks was calculated using an Analysis of covariance (ANCOVA) model with baseline mean 24 hour ambulatory diastolic blood pressure as a covariate.

PRIMARY outcome

Timeframe: Baseline, Week 6

Population: Participants from the Full analysis set (consisting of all randomized patients) for whom data was available at Baseline and Week 6.

An Ambulatory Blood Pressure Monitoring (ABPM) device was attached to the non-dominant arm of the participant. The mean of Blood Pressure readings during the 24 hour period were calculated. The difference of the 24 hour MADBP from baseline to the 24 hour MADBP at 6 weeks was calculated using an Analysis of covariance (ANCOVA) model with baseline mean 24 hour ambulatory diastolic blood pressure as a covariate.

SECONDARY outcome

Timeframe: Baseline, Week 6

Population: Participants from the Full analysis set (consisting of all randomized patients) for whom data was available at Baseline and Week 6.

After the patient had been sitting for 5 minutes, with the back supported and both feet placed on the floor, systolic and diastolic blood pressures were measured 3 times using a calibrated standard sphygmomanometer and appropriate size cuff. The repeat sitting measurements were made at 1-2 minute intervals and the mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure for that visit. A negative number indicates lowered blood pressure. The ANCOVA model used baseline as a covariate.

After the patient had been sitting for 5 minutes, with the back supported and both feet placed on the floor, systolic and diastolic blood pressures were measured 3 times using a calibrated standard sphygmomanometer. The mean of these 3 sitting blood pressure measurements was used as the average sitting blood pressure at visit 3 (week 6). Blood pressure control was defined as having a mean sitting diastolic blood pressure (msDBP) \<90 mm Hg and a mean sitting systolic blood pressure (msSBP) \<140 mm Hg.
