TELMA - Observational Study in Daily Medical Practice of the Effectiveness of Telmisartan for Treatment of Hypertension in Patients With and Without Confirmed Albuminuria in Belgium
An observational study of Hypertension, run by Boehringer Ingelheim at 936 sites in Belgium.
Trial summary
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. Read more about this study

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 participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Telmisartan | Not described | |
| Telmisartan + hydrochlorothiazide | Not described |
What is being measured
The primary outcome is the main question the study is designed to answer.
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)
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
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
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
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
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

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 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?
