Study groups in NCT00446563
Study groupRoleWhat they receive
Amlodipine + ValsartanExperimentalParticipants received 160 mg Valsartan and 5 mg amlodipine orally once a day for 52 weeks. If blood pressure was not normalized at week 4, treatment was uptitrated to valsartan/amlodipine 160/10 mg. Participants with still uncontrolled hypertension could receive add-on antihypertensive medication.
Receives: Drug: Valsartan; Drug: Amlodipine
Losartan + HydrochlorothiazideActive comparatorParticipants received 100 mg losartan and 12.5 mg Hydrochlorothiazide (HCT) orally once a day for 52 weeks. If blood pressure was not normalized at week 4, treatment was uptitrated to losartan/HCT 100/25 mg, respectively, until end of study. Participants with still uncontrolled hypertension could receive add-on antihypertensive medication.
Receives: Drug: Hydrochlorothiazide; Drug: Losartan

What is being measured

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

  1. Change From Baseline in Left Ventricular Mass Index (LVMI) Measured Via Magnetic Resonance Imaging (MRI)

  4. Change From Baseline to the End of Study in Left Ventricular Ejection Fraction (LVEF) Assessed by MRI

    Ejection fraction is a measurement of the percentage of blood that is pumped out of a filled ventricle with each heartbeat.

    Measured: Baseline to week 52

  5. Change From Baseline to the End of Study in Left Ventricular End-diastolic Volume (LVEDV) Assessed by MRI

    Measured: Baseline to week 52

  6. Change From Baseline to the End of Study in Left Ventricular End-diastolic Volume (LVEDV) Normalized to Body Surface Area Assessed by MRI

    Measured: Baseline to week 52

  7. Change From Baseline to the End of Study in Left Ventricular End-Systolic Volume (LVESV) Assessed by MRI

    Measured: Baseline to week 52

  8. Change From Baseline to the End of Study in Left Ventricular End-Systolic Volume (LVESV) Normalized to Body Surface Area Assessed by MRI

    Measured: Baseline to week 52

  9. Change From Baseline to the End of Study in Left Atrial (LA) Area Assessed by MRI

    Measured: Baseline to week 52

  10. Change From Baseline to the End of Study in the Ascending Aortic Diameter Assessed by MRI

    Measured: Baseline to week 52

  11. Change From Baseline to End of Study in Levels of N-terminal Pro-B Type Natriuretic Peptide (NT-proBNP)

    Measured: Baseline to week 52

  12. Change From Baseline to End of Study in Levels of High-sensitivity C-reactive Protein (Hs-CRP)

    Measured: Baseline to week 52

  13. Percentage of Participants Achieving Target Blood Pressure at Week 52

    Target blood pressure defined as having a mean sitting systolic blood pressure (MSSBP) < 140 mm Hg and a mean sitting diastolic blood pressure (MSDBP) < 90 mm Hg.

    Measured: Week 52

  14. Percentage of Participants Who Experienced Adverse Events (AEs)

    An adverse event was the appearance or worsening of any undesirable sign, symptom, or medical condition occurring after obtaining informed consent even if the event was not considered to be related to study drug. Medical conditions/diseases present before obtaining informed consent were only considered adverse events if they worsened after study start. Abnormal laboratory values or test results constituted adverse events only if they induced clinical signs or symptoms, required study drug discontinuation or required therapy.

    Measured: Baseline to week 52

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Valsartan, Amlodipine and Hydrochlorothiazide in people with Hypertension; Hypertrophy, Left Ventricular, run by Novartis at 1 site in Germany.

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 3 inclusion and 5 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 11 May 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. 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 27 Apr 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?

Change From Baseline in Left Ventricular Mass Index (LVMI) Measured Via Magnetic Resonance Imaging (MRI) (time frame: Baseline to week 52). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00446563, which also lists 1 linked publication.

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 11 May 2011.
