About this study

Official title: Clinical Study to Evaluate the Efficacy and Safety of the Combination Therapy Candesartan Cilexetil 32 mg Plus Hydrochlorothiazide 25 mg in Patients With Severe Hypertension

The purpose of this study is to see if Candesartan, once daily (QD), added with Hydrochlorothiazide may be helpful in treating people with newly diagnosed severe essential hypertension.

Read the detailed description

Medical data show a link between blood pressure and the risk of heart disease (cardiovascular disease) such as stroke and heart attack. Clinical trials have shown that lowering blood pressure in patients with high blood pressure (hypertension) reduces the number of cardiovascular events.

Many people still have untreated hypertension. There are many reasons why target blood pressure is not reached. One is that most patients need more than one antihypertensive drug in order to lower high blood pressure. Other reasons include poor patient compliance with taking their drugs.

Combining drugs that lower high blood pressure and have similar ways of working in the body may help high blood pressure and lower the risk for medication-related side effects. One of several drug combinations recommended for the treatment of high blood pressure is an angiotensin receptor blocker and a thiazide diuretic. Guidelines also note that combination tablets may improve patient compliance with taking their drugs.

Candesartan is an angiotensin type-1 receptor blocker. Hydrochlorothiazide is a diuretic with blood pressure-lowering effect. This study will combine both of these drugs in one pill and see how it works in people taking part in this study.

    Measured: Baseline and Week 9.

  2. Change from Baseline in Diastolic Blood Pressure at Week 9.

    The change between Diastolic Blood Pressure (DBP) value collected at week 9 or final visit and DBP value collected at baseline.

    Measured: Baseline and Week 9.

Secondary outcomes (6)
  1. Percentage of subjects showing a decrease in SBP to less than 140 mmHg and/or a decrease of SBP by at least 20 mmHg AND a decrease in DBP to less than 90 mmHg and/or a decrease of DBP by at least 10 mmHg.

    Percentage of participants at week 9 or final visit showing a decrease in SBP to less than 140 mmHg and/or a decrease of SBP by at least 20 mmHg AND a decrease in DBP to less than 90 mmHg and/or a decrease of DBP by at least 10 mmHg.

    Measured: Week 9.

  2. Percentage of subjects showing a decrease in SBP to less than 130 mmHg and/or a decrease of SBP by at least 20 mmHg AND a decrease in DBP to less than 80 mmHg and/or a decrease of DBP by at least 10 mmHg.

    Percentage of participants at week 9 or final visit showing a decrease in SBP to less than 130 mmHg and/or a decrease of SBP by at least 20 mmHg AND a decrease in DBP to less than 80 mmHg and/or a decrease of DBP by at least 10 mmHg.

    Measured: Week 9.

  3. Change from Baseline in Pulse Rate at Week 9.

    The change between Pulse Rate measured at week 9 and Pulse Rate measured at baseline.

    Measured: Baseline and Week 9.

  4. Change from Baseline in Systolic Blood Pressure at Final Visit.

    The change between the Systolic Blood Pressure value collected at week 9 or final visit and the Systolic Blood Pressure value collected at baseline.

    Measured: Baseline and Final Visit (up to Week 9)

  5. Change in Baseline in Diastolic Blood Pressure at Final Visit.

    The change between the Diastolic Blood Pressure value collected at week 9 or final visit and the Diastolic Blood Pressure value collected at baseline.

    Measured: Baseline and Final Visit (up to Week 9)

  6. Change from Baseline in Pulse Rate at Final Visit.

    The change between Pulse Rate measured at week 9 or final visit and the Pulse Rate measured at baseline.

    Measured: Baseline and Final Visit (up to Week 9)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Candesartan cilexetil and hydrochlorothiazide in people with Hypertension, run by Takeda at 16 sites in 2 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 4 inclusion and 14 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 14 Jul 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in Germany, Ukraine. 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?

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?

Change from Baseline in Systolic Blood Pressure at Week 9. (time frame: Baseline and Week 9.). The study lists 2 primary outcomes in all. 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 14 Jul 2010.
