About this study

Official title: Efficacy and Safety of Irbesartan/Amlodipine Fixed Combination Therapy Compared With Amlodipine Monotherapy in Hypertensive Patients Uncontrolled on Amlodipine 5 mg Monotherapy

Primary Objective:

  • To demonstrate that the antihypertensive efficacy of the fixed combination irbesartan/amlodipine 150/5 mg is superior to that of amlodipine 5 mg monotherapy in lowering systolic blood pressure (SBP) as measured by home blood pressure measurement (HBPM) after 5 weeks of treatment (W5)

Secondary Objective:

  • To compare the antihypertensive efficacy of the fixed combination irbesartan/amlodipine 150/5 mg with that of amlodipine 5 mg monotherapy after 5 weeks of treatment (W5)
  • To compare the antihypertensive efficacy of the fixed combination therapy irbesartan/amlodipine 150/10 mg with that of amlodipine 10 mg monotherapy at the end of treatment (W10)
  • To examine in each treatment group the change from week 5 to week 10 in SBP and diastolic blood pressure (DBP) assessed by HBPM and by office blood pressure measurement (OBPM)
  • To determine the incidence and severity of adverse events

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing irbesartan/amlodipine and amlodipine in people with Hypertension, run by Sanofi at 40 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 8 inclusion and 15 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 26 Oct 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 40 sites in Brazil, Mexico, Chile, Lebanon, Egypt 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Mean home systolic blood pressure (time frame: At randomisation and week 5). 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 NCT00956644, 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 26 Oct 2010.
