Trial Outcomes & Findings for Efficacy and Safety of Valsartan/Amlodipine in Patients With Mild to Moderate Essential Hypertension (NCT NCT01001572)

NCT ID: NCT01001572

Last Updated: 2011-05-24

Results Overview

Three arterial blood pressure (BP) determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSDBP was calculated comparing the Week 8 readings to the readings taken at Baseline. The change from baseline in MSDBP was analyzed using an analysis of covariance model (ANCOVA) with treatment and center (pooled as appropriate) as factors and centered baseline MSDBP as a covariate.

Participant Flow

932 participants were entered into the single-blind valsartan 160 mg arm. 278 participants were discontinued from the single-blind arm. 654 participants were randomized into the double-blind treatment phase; 329 to the Valsartan/amlodipine arm and 325 to the valsartan alone arm.

PRIMARY outcome

Timeframe: Baseline and Week 8

Population: Full Analysis Set includes all randomized participants who had both baseline and at least one post-baseline efficacy measurement. Last Observation Carried Forward.

Three arterial blood pressure (BP) determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSDBP was calculated comparing the Week 8 readings to the readings taken at Baseline. The change from baseline in MSDBP was analyzed using an analysis of covariance model (ANCOVA) with treatment and center (pooled as appropriate) as factors and centered baseline MSDBP as a covariate.
