About this study

Official title: Add-on Study of Hydrochlorothiazide in Patients With Moderate to Severe Hypertension Not Achieving Target Blood Pressure on Olmesartan/Amlodipine Alone

Both Olmesartan (OLM)/Amlodipine (AML) combination and Hydrochlorothiazide (HCTZ) have proven to be efficacious and safe in lowering blood pressure, but may not always be sufficient. This study is to test efficacy and safety of the combination of OLM/AML and HCTZ in hypertensive patients whose blood pressure is not adequately controlled with OLM/AML alone. The following treatments will be included in the trial: OLM 40mg/AML 10mg; OLM 40mg/AML 10 mg/HCTZ 12.5 mg; OLM 40 mg/AML 10 mg/HCTZ 25 mg. The trial has four periods. The treatments that will be used are as follows:

Period 1 - OLM 40mg/AML 10mg; Period 2 - OLM 40mg/AML 10mg or OLM 40mg/AML 10 mg/HCTZ 12.5 mg or OLM 40 mg/AML 10 mg/HCTZ 25 mg; Period 3 - OLM 40mg/AML 10 mg/HCTZ 12.5 mg; Period 4 - Period 3 responders: OLM 40mg/AML 10 mg/HCTZ 12.5 mg; Period 4 - Period 3 non-responders: OLM 40mg/AML 10 mg/HCTZ 12.5 mg or OLM 40 mg/AML 10 mg/HCTZ 25 mg

    The number of non-responding participants who achieved their blood pressure goals at the end of Period 4. Achieving blood pressure goal is defined as seated blood pressure <140/90 mm Hg; 130/80 mm Hg for participants with diabetes and/or other chronic renal and/or chronic cardiovascular disease. Three cuff blood pressure measurements were taken at each visit.

    Measured: week 24 to week 32

  8. In Non-responders, the Change in 24-hour Diastolic Blood Pressure Assessed by 24-hour Ambulatory Blood Pressure Measurement.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Olmesartan medoxomil 40 mg - Amlodipine 10 mg, Olmesartan 40mg-Amlodipine 10mg-Hydrochlorothiazide 12.5mg and Olmesartan 40mg-Amlodipine 10mg-Hydrochlorothiazide 25mg in people with Essential Hypertension, run by Daiichi Sankyo at 117 sites in 14 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 10 inclusion and 11 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 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 117 sites in France, Spain, Ukraine, Poland, Russia and 9 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 22 Nov 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 in Seated Diastolic Blood Pressure (SeDBP) of the Triple Combinations OM/AML/HCTZ 40/10/12.5 and 40/10/25 mg vs. OM/AML 40/10 mg (time frame: baseline (8 weeks) to 16 weeks). 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 11 Jan 2019.
