Condition(s) targeted: Hypertension

Intervention: Telmisartan (Drug); Valsartan (Drug); Placebo (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Boehringer Ingelheim


The primary aim of the trial was to compare the effect of telmisartan and valsartan in lowering ambulatory diastolic and/or systolic blood pressure in the last six hours of the dosing interval. Secondary variables included changes from baseline in diastolic and systolic blood pressures during other times during the 24-hour ABPM profile, changes from baseline in seated trough diastolic and systolic blood pressures as measured by manual cuff, and responder rates. Assessment of safety was also considered. Adverse events and use of concomitant therapies were monitored at each study visit. Blood pressure and heart rate were collected at each visit. Physical examination, electrocardiograms (ECG) and laboratory tests were completed during the trial as well.

Clinical Details

Official title: A Prospective Randomized Open-Label Blinded End Point (PROBE) Trial Comparing MICARDIS (Telmisartan) (80 mg QD) and Valsartan (80 mg QD) in Patients With Mild-to-Moderate Hypertension Using Ambulatory Blood Pressure Monitoring.

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Changes from baseline in diastolic and systolic blood pressure during the last 6 hours of a 24-hour dosing interval measured by ambulatory blood pressure monitoring (ABPM)

Secondary outcome:

Changes from baseline in diastolic and systolic blood pressures during other times during 24-hr ABPM profile

Changes from baseline in seated trough diastolic and systolic blood pressures as measured by manual cuff sphygmomanometer

Blood pressure responder rates based on ABPM

Blood pressure responder rates based manual cuff measurements

Number of patients with adverse events


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria:

- Mild to moderate hypertension defined as mean seated diastolic blood pressure

measurement of ≥ 95 mm Hg and ≤ 114 mm Hg, measured by manual cuff sphygmomanometer, on the last visit (Visit 6) of the four-week placebo run-in period (baseline BP)

- Mean seated systolic blood pressure ≥ 140 mm Hg and ≤ 200 mm Hg, measured by manual

cuff at Visit 6 (baseline BP)

- A 24-hour mean ABPM measurement of ≥ 130/85 mm Hg evaluated at Visit 7 (baseline

- SGPT (ALT) (serum glutamate pyruvate transaminase) or SGOT (AST) (serum

glutamate oxaloacetate transaminase) greater than two times the upper limit of normal

- Serum creatinine > 2. 3 mg/dL

- At screening (Visit 1): clinically relevant sodium depletion, hyperkalemia, or


- Known or suspected secondary hypertension

- Bilateral renal artery stenosis; renal artery stenosis in a solitary kidney;

post-renal transplant patients, presence of only one functioning kidney

(congestive heart failure) III-IV

- Unstable angina within the past three months

- Stroke within the past six months

- Myocardial infarction or cardiac surgery within the past three months

- PTCA (percutaneous transluminal coronary angioplasty) within the past three months

- History of angioedema

- Sustained ventricular tachycardia, atrial fibrillation, atrial flutter or other

clinically relevant cardiac arrhythmias as determined by the investigator

- Hypertrophic obstructive cardiomyopathy, aortic stenosis, hemodynamically relevant

stenosis of the aortic or mitral valve

- Administration of digoxin or other digitalis-type drugs

- Patients with insulin-dependent diabetes mellitus whose diabetes has not been stable

and controlled for at least the past three months as defined by HbA1C ≥ 10%

- Known drug or alcohol dependency within the past one year period

- Concomitant administration of medications known to affect blood pressure, except

medications allowed by the protocol

- Night shift workers who routinely sleep during the daytime and whose work hours

include midnight to 4: 00 AM

- Patients receiving any investigational therapy within one month of signing the

informed consent form. Note that patients who have participated in previous MICARDIS® (telmisartan) studies may participate in this study provided there has been at least one month between discontinuing the previous study and signing the consent for the present study

- Known hypersensitivity to any component of the formulations

- Any clinical condition which, in the opinion of the investigator, would not allow

safe completion of the protocol and safe administration of trial medication
