What participants receive

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

  • Valsartan + HCTZDrug

    At week 0 patients received V+HCTZ 160+12.5 mg capsules. Subjects not at BP goal <140/90 mmHg were uptitrated to V+HCTZ 320+12.5 mg at week 4 and if needed to V+HCTZ 320+25 mg at week 8 or 12.

  • ValsartanDrug

    At week 0 patients received Valsartan(V) 160 mg capsule. Subjects not at BP goal <140/90 mmHg were uptitrated to V+HCTZ 160+12.5 mg at week 4 and if needed to V+HCTZ 320+12.5 mg at week 8, and V+HCTZ 320+25 mg at week 12.

  • HCTZDrug

    At week 0 patients received HCTZ 12.5 mg capsule. Subjects not at BP goal <140/90 mmHg were uptitrated to V+HCTZ 160+12.5 mg at week 4 and if needed to V+HCTZ 320+12.5 mg at week 8, and V+HCTZ 320+25 mg at week 12.

What is being measured

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

  1. Change From Baseline to Week 4 in Office Cuff Mean Sitting Systolic Blood Pressure (MSSBP)

    Measured: Baseline and Week 4

Secondary outcomes (5)
  1. Change From Baseline to Week 4, 8, 12 and 16 in Office Cuff Mean Sitting Diastolic Blood Pressure (MSDBP)

    Measured: Baseline and Weeks 4, 8, 12 and 16

  2. Change From Baseline to Weeks 8, 12 and 16 in Office Cuff Mean Sitting Systolic Blood Pressure (MSSBP)

    Measured: Baseline and Weeks 8, 12, and 16

  3. Cumulative Percentage of Patients Achieving the Blood Pressure Control of < 140/90 mmHg

    Cumulative refers to achieving of blood pressure control before or at the corresponding visit.

    Measured: Weeks 4, 8, 12 and 16

  4. Cumulative Percentage of Patients Achieving Blood Pressure Goal (MSSBP < 140 mmHg)

    Cumulative refers to achieving blood pressure goal before or at the corresponding visit.

    Measured: Weeks 4, 8, 12 and 16

  5. Time in Weeks to Achieving the First Treatment Success (Defined as the Time of the First Achievement of the Target Blood Pressure Goal [MSSBP/MSDBP <140/90 mmHg])

    Measured: During 16 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Valsartan + HCTZ, Valsartan and HCTZ in people with Hypertension, run by Novartis Pharmaceuticals at 20 sites in United States.

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 5 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 19 Apr 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in United States. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 15 Dec 2010). 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 to Week 4 in Office Cuff Mean Sitting Systolic Blood Pressure (MSSBP) (time frame: Baseline and Week 4). 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 NCT00698646, which also lists 4 linked publications.

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 19 Apr 2011.
