Efficacy and Safety of Valsartan and Amlodipine (± HCTZ) in Adults With Moderate, Inadequately Controlled Hypertension

July 27, 2020 updated by: Novartis

An Open-label, Multicenter Study to Evaluate the Efficacy and Tolerability of a 4 Week Therapy With the Fixed Dose Combination of Amlodipine 10 mg Plus Valsartan 160 mg in Hypertensive Patients Not Adequately Responding to a 4 Week Therapy With the Free Combination of an Angiotensin Receptor Blocker (Olmesartan 20 mg) Plus Amlodipine 10 mg

This study will evaluate the efficacy and safety of valsartan and amlodipine in fixed dose combination in adults with moderate, inadequately controlled hypertension. There was an optional study extension for eligible patients who wanted to participate that contains the triple therapy (ie, hydrochlorothiazide+ amlodipine/valsartan).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Mean Sitting Diastolic Blood Pressure (msDBP) During the Core Phase of the Study
Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8)
The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. 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 blood pressure were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.
Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8)
Change in Mean Sitting Diastolic Blood Pressure (msDBP) During the Extension Phase of the Study
Time Frame: Baseline Phase 3 (Week 8) to end of Phase 3 (Week 12)
The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. 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 blood pressure were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.
Baseline Phase 3 (Week 8) to end of Phase 3 (Week 12)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Mean Sitting Systolic Blood Pressure (msSBP) During the Core Phase of the Study
Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8)
The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. 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 blood pressure were measured 3 times at 1-2 minute intervals.

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, SP and DP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.
Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8)

Percentage of Patients Who Achieved Normalized Blood Pressure During the Core Phase of the Study
Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8)
Normalized Blood Pressure was defined as a msSBP < 140 mmHg and/or a msDBP < 90 mmHg.
Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8)
Percentage of Patients Who Achieved a Protocol-defined Blood Pressure Response During the Core Phase of the Study
