What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ValsartanDrug

  • EnalaprilDrug

    Enalapril (10, 20, and 40 mg, weight stratified). All study medications were taken orally once daily, at approximately the same time each day, with or without food.

  • placebo matched to enalaprilDrug

    Placebo matched to enalapril. All study medications were taken orally once daily, at approximately the same time each day, with or without food.

  • placebo matched to valsartanDrug

    placebo matched to valsartan. All study medications were taken orally once daily, at approximately the same time each day, with or without food.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Adverse Events

    Measured: Start of extension (week 13) to end of study (Week 26 in non-CKD patients and Week 50 in CKD patients)

Secondary outcomes (4)
  1. Change in Mean Sitting Diastolic Blood Pressure (msDBP) From Baseline to Week 26

    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.

    Measured: Core Baseline (Week 0) to Week 26

  2. Percentage of Non-CKD Patients Achieving Systolic and Diastolic BP Control at Week 26

    Systolic and diastolic blood pressure (BP) control was defined as msSBP and msDBP < 95th percentile for gender, age, and height. 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.

    Measured: Week 26

  3. Change From Baseline in Post-dosing 24-hour Mean Systolic and Diastolic Ambulatory Blood Pressure at Week 20

    24-hour ambulatory blood pressure monitoring (ABPM) was conducted once during the extension in a subset of patients at selected centers. For all patients who completed a qualifying ABPM at baseline, an ABPM was to be performed at Week 20. The ABPM monitor was placed on the non-dominant arm.

    Measured: Core Baseline (Week 0) to Week 20

  4. Change in Mean Sitting Systolic Blood Pressure (msSBP) From Baseline to Week 26

    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.

    Measured: Core Baseline (Week 0) to Week 26

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Valsartan and Enalapril in people with Hypertension, run by Novartis Pharmaceuticals at 9 sites in 9 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Jul 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Belgium, France, Germany, Hungary and 4 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Jun 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Adverse Events (time frame: Start of extension (week 13) to end of study (Week 26 in non-CKD patients and Week 50 in CKD patients)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jul 2011.
