Trial Outcomes & Findings for Study to Evaluate the Efficacy and Safety of Aliskiren Alone and in Combination With Amlodipine in Essential Hypertension (NCT NCT00739973)

NCT ID: NCT00739973

Last Updated: 2011-06-06

Results Overview

The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

• Recruitment status: COMPLETED
• Study phase: PHASE3
• Target enrollment: 2694 participants
• Primary outcome timeframe: Baseline to end of study (Week 8)

Participant Flow

A total of 2694 patients enrolled in the single-blind, placebo run-in period (2 to 4 weeks) of the study. A total of 1688 patients were randomized into the double-blind treatment period (8 weeks). Three patients were mis-randomized, as they were discontinued from the single-blind period and were not treated in the double-blind period.

Mis-randomized participants refer to participants who were not qualified for randomization but were inadvertently randomized into the study. These participants did not receive study drug.

The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

Mis-randomized participants refer to participants who were not qualified for randomization but were inadvertently randomized into the study. These participants did not receive study drug.

The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

Mis-randomized participants refer to participants who were not qualified for randomization but were inadvertently randomized into the study. These participants did not receive study drug.

The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

Mis-randomized participants refer to participants who were not qualified for randomization but were inadvertently randomized into the study. These participants did not receive study drug.

The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

Blood pressure response in msSBP is defined as a mean sitting systolic blood pressure < 140 mmHg or a >= 20 mmHg reduction from baseline. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic/diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.
