About this study

Official title: A Comparison of Telmisartan Effectiveness in Hypertensive Patients With and Without Albuminuria.

This study was carried out in the context of daily medical practice to compare the effectiveness of telmisartan in the treatment of hypertension complicated or not with the presence of protein in the urine, which is called albuminuria. Hypertension is a chronic, treatable but not curable disease and is defined as a combination of a systolic blood pressure of 140 mmHg or more and a diastolic pressure of 90 mmHg or more. The kidneys are often the first organs damaged by hypertension; renal damage could easily be diagnosed using a urine dipstick and should be part of a routine examination in hypertensive patient. The aim of the study is to see if the decrease of blood pressure (both systolic and diastolic) after approximately 12 weeks of treatment with telmisartan in patients with albuminuria is the same or different to that in patients without albuminuria. Every patient participating should have two visits, approximately 12 weeks apart where his/her blood pressure was checked and a few questions about is concomitant disease and drugs were asked.

What is being measured

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

  1. Percentage of Patients With Controlled Blood Pressure

    Systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) < 90 mmHg if the patient has:

    • no chronic renal insufficiency or macroalbuminuria-dipsticks negative,
    • albuminuria is < 300 mg/24h or < 200 mg albumin per gram of creatinine
    • no diabetes or SBP < 130 mmHg and DBP < 80 mmHg if the patient has:
    • chronic renal insufficiency or macroalbuminuria-dipsticks are positive, albuminuria ≥ 300 mg/24h or ≥ 200 mg albumin per gram of creatinine
    • diabetes (type 1 or 2)

    Measured: approximately 12 weeks (10 to 14 weeks) after baseline

Secondary outcomes (5)
  1. Mean Difference in Systolic Blood Pressure

    The fall in systolic blood pressure (SBP) after approximately 12 weeks of treatment including telmisartan defined as SBP (baseline) - SBP (12 weeks) expressed in mmHg

    Measured: baseline and approximately 12 weeks

  2. Mean Difference in Diastolic Blood Pressure

    The fall in diastolic blood pressure (DBP) after approximately 12 weeks of treatment including telmisartan defined as DBP (baseline) - DBP (12 weeks) expressed in mmHg

    Measured: baseline and approximately 12 weeks

  3. Percentage of Patients With a Decrease of Systolic Blood Pressure (SBP) ≥ 10 mmHg (Responders)

    The response in SBP after approximately 12 weeks of treatment including telmisartan defined as a fall in SBP (SBP (baseline) - SBP (12 weeks) ≥ 10 mmHg

    Measured: approximately 12 weeks (10 to 14 weeks) after baseline

  4. Percentage of Patients Presenting an Adverse Event (AE)

    Percentage of patients with any adverse events during the study period, related or not to investigational drug

    Measured: baseline to the end of study period

  5. Percentage of Patients With Positive to Negative Shift in Albuminuria

    Percentage of patients shifting from with (positive) albuminuria at baseline to without (negative) albuminuria after approximately 12 weeks

    Measured: Approximately 12 weeks (10 to 14 weeks) after baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Hypertension, run by Boehringer Ingelheim at 936 sites in Belgium.

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 1 inclusion and 1 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 17 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 936 sites in Belgium. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Nov 2009). 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?

Percentage of Patients With Controlled Blood Pressure (time frame: approximately 12 weeks (10 to 14 weeks) after baseline). 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 17 Jun 2014.
