Condition(s) targeted: Hypertension

Intervention: Telmisartan + hydrochlorothiazide (Drug); Telmisartan (Drug); Placebo (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Boehringer Ingelheim

Summary

An eight week study to compare the effect of a fixed dose combination of Telmisartan 40 mg plus hydrochlorothiazide (HCTZ) 12. 5 mg to Telmisartan 40 mg alone on diastolic and systolic blood pressure in patients who fail to respond adequately to telmisartan monotherapy.

Clinical Details

Official title: An Eight Week Randomized, Double-Blind Study Comparing a Fixed Dose Combination of Telmisartan 40 mg Plus Hydrochlorothiazide 12.5 mg to Telmisartan 40 mg in Patients Who Fail to Respond Adequately to Treatment With Telmisartan 40 mg

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Treatment

Primary outcome: Change from baseline in seated diastolic blood pressure (DBP)

Secondary outcome:

Change from baseline in seated systolic blood pressure (SBP)

Blood pressure control

Systolic blood pressure response

Incidence of adverse events

Change from baseline in physical examination

Change from baseline in heart rate

Change from baseline in laboratory parameters

Change from baseline in 12-lead ECG (electrocardiogram)

Eligibility

Minimum age: 18 Years. Maximum age: 80 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- History of mild-to-moderate hypertension

- Patients who fail to respond adequately to telmisartan monotherapy

Exclusion Criteria:

- Patients taking more than three anti-hypertensive medications at the screening visit

continue using an acceptable method throughout the study. Acceptable methods of birth control include intrauterine device (IUD), oral, implantable or injectable contraceptives

- Any women:

- Who has a positive serum pregnancy test at screening (Visit 1) or baseline

(Visit 3)

- Who is nursing

- Hepatic and/or renal dysfunction as defined by the following laboratory parameters

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

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

- Serum creatinine > 2. 3 mg/dL

- Clinically relevant sodium depletion, hyperkalemia, or hypokalemia at baseline

- 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 (CHF) (NYHA (New York Heart Association) functional class

CHF 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 symptoms characteristic of angioedema during treatment with ACE

inhibitors, angiotension II antagonists, thiazide diuretics, β-blockers or calcium channel blockers

- 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 Type I or Type II diabetes mellitus whose diabetes has not been stable

and controlled for at least the past three months as defined by an 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

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

informed consent form. Patients who have participated in previous telmisartan (except if they were on the fixed dose combination in the 502. 261 study or enrolled in the 502. 321 open-label extension study) 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
