Trial Outcomes & Findings for Efficacy/Safety of Valsartan Plus Amlodipine and Amlodipine Alone in Patients With Hypertension (NCT NCT00413049)

NCT ID: NCT00413049

Last Updated: 2011-04-29

Results Overview

Blood pressure (BP) was measured with a calibrated aneroid or mercury sphygmomanometer. The arm in which the highest sitting diastolic BP was found at study entry was used for all subsequent readings. At each visit, after the patient was in a sitting position for five minutes, systolic/diastolic BP was measured 3 times at 1-2-minute intervals. The mean of the 3 measurements was calculated. A negative change score indicates lowered BP.

PRIMARY outcome

Timeframe: Baseline to end of study (Week 8)

Population: Intent-to-Treat (ITT): All randomized patients who had baseline and at least one post-baseline efficacy measurement, ie, any post-baseline measurement of primary or secondary efficacy variables. For patients who did not complete the Week 8 assessment, a last observation carried forward (LOCF) approach was used.

Blood pressure (BP) was measured with a calibrated aneroid or mercury sphygmomanometer. The arm in which the highest sitting diastolic BP was found at study entry was used for all subsequent readings. At each visit, after the patient was in a sitting position for five minutes, systolic/diastolic BP was measured 3 times at 1-2-minute intervals. The mean of the 3 measurements was calculated. A negative change score indicates lowered BP.

A patient achieved a diastolic response if their msDBP \< 90 mmHg at Week 8 or they had a ≥ 10 mmHg decrease in msDBP compared to baseline at the end of the study (Week 8). Blood pressure (BP) was measured with a calibrated aneroid or mercury sphygmomanometer.

At each visit, after the patient was in a sitting position for five minutes, systolic/diastolic BP was measured 3 times at 1-2-minute intervals. The mean of the 3 measurements was calculated.

SECONDARY outcome

Timeframe: Baseline to end of study (Week 8)

Two 24 hour ambulatory blood pressure monitoring (ABPM) evaluations were performed, one at baseline prior to randomization and one at Week 8 (end of study), in a subset of the intent-to-treat population of patients. For each evaluation, the ABPM device was attached to the non-dominant arm of the patient. A correlation was made between the ABPM device readings and measurements taken with a mercury sphygmomanometer and stethoscope. Following the correlation procedure, BP was measured at study specified intervals. A negative change score indicates lowered BP.
