TRANSCEND(TM) Trial Results Presented at European Society of Cardiology Congress and Published in The Lancet

In high-risk patients who cannot tolerate an angiotensin-converting enzyme (ACE) inhibitor, the TRANSCEND trial was designed to investigate potential cardiovascular risk reduction benefits using the second-generation angiotensin II receptor blocker (ARB) telmisartan. Telmisartan was compared to placebo on top of standard therapy (including anti-hypertensives, anti-platelet therapy and statins).

The TRANSCEND trial was part of the ONTARGET(TM) Trial Program, the largest clinical trial ever undertaken with an ARB, involving more than 31,000 high-risk cardiovascular patients with either normal or controlled blood pressure. The ONTARGET Trial Program was based on the design of the landmark HOPE trial and encompassed two randomized, double-blind, multi-center international outcome trials: ONTARGET**, the main trial with results reported in March 2008,(3) and TRANSCEND, the parallel trial.

"Previously, the ONTARGET trial showed that telmisartan was as effective as the ACE inhibitor ramipril in reducing the risk of cardio- and cerebrovascular events, but with a lower rate of discontinuations. For high- risk patients who cannot tolerate an ACE inhibitor, the TRANSCEND results could represent an important step forward," said Michael Weber, M.D., professor of medicine at the State University of New York, Downstate College of Medicine.

It was also published that all cardiovascular hospitalizations were significantly reduced with telmisartan (894 vs. 980; p=0.025). Therapy with telmisartan was well tolerated and showed a trend toward a lower rate of discontinuation (640 patients discontinued taking telmisartan vs. 707 taking placebo, p=0.051). The most frequently reported reasons for discontinuation were hypotensive symptoms, syncope, cough, diarrhea, angioedema and renal abnormalities.(1)

TRANSCEND included 5,926 patients from 40 countries who were at high risk for cardiovascular disease (patients older than 55 years, who have had myocardial infarction, peripheral arterial occlusive disease, stroke or transient ischaemic attacks or suffer from diabetes mellitus and additional risk factors) and intolerant to widely-prescribed ACE inhibitors. Patients in the trial were randomized to treatment with telmisartan 80mg/day or placebo.

It has been reported in medical literature that the incidence of patients with hypertension who are intolerant to ACE inhibitors ranges between 10-39%,(4-6) which often leads to discontinuation of treatment leaving patients unprotected. Side effects associated with ACE inhibitors include intolerable cough and rare, but potentially life threatening, angioedema.(4-6)

"The landmark ONTARGET and TRANSCEND trials have contributed significant and important clinical information to the cardiovascular community and could help uncover new treatment strategies to improve patient outcomes and care," said Thor Voigt, M.D., senior vice president, Medicine and Drug Regulatory Affairs, Boehringer Ingelheim Pharmaceuticals, Inc.

About the ONTARGET Trial Program

The ONTARGET Trial Program was the largest clinical trial ever undertaken with an ARB, involving more than 31,000 high-risk cardiovascular patients with either normal or controlled blood pressure. The ONTARGET Trial Program encompassed two randomized, double-blind, multi-center international outcome trials: ONTARGET, the main trial, and TRANSCEND, the parallel trial.

ONTARGET evaluated more than 25,600 high-risk cardiovascular patients with normal blood pressure or controlled high blood pressure and a history of a broad range of cardiovascular diseases. The study found that telmisartan is equally effective as the current standard, ramipril, in reducing the risk of cardiovascular death, myocardial infarction, stroke and hospitalization for congestive heart failure, and resulted in fewer discontinuations. Telmisartan is now the only ARB to have demonstrated cardio and vascular risk reduction benefits beyond lowering blood pressure in this high-risk population; these benefits may be attributed to the specific pharmacological properties and mode of action of the drug.(2)

The combined primary endpoint in both the TRANSCEND and ONTARGET trials included cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and hospitalization for congestive heart failure. The secondary endpoint in the TRANSCEND trial was the effect of telmisartan treatment on the incidence of newly diagnosed congestive heart failure, revascularization procedures, newly diagnosed diabetes mellitus, cognitive decline and dementia and new onset of atrial fibrillation.

More than 700 sites throughoutAsia,Australia,New Zealand,Europe, North/South America andSouth Africa participated in the ONTARGET Trial Program. The ONTARGET Steering Committee consisted of scientists from McMaster University inOntario, Canada; Oxford University inOxford, England; the University ofAuckland inAuckland, New Zealand; and Boehringer Ingelheim.

The ONTARGET Trial Program was investigational and was conducted to expand scientific knowledge of telmisartan. Note that the trial included treatment for conditions outside the approved indication for telmisartan.

About Cardiovascular Disease

Cardiovascular disease (CVD) is the number one cause of death and disability globally(7) and is responsible for one of every three deaths worldwide -- an estimated 17 million people per year.(8) CVD causes more deaths than cancer, chronic respiratory disease and diabetes combined.(9) By 2020, it is predicted that CVD will surpass infectious diseases to become the largest cause of death and disability worldwide.(10) It is also contributes significantly to the escalating costs of health care. In 2006, the cost of CVD in the U.S. was estimated at $403.1 billion.(11)

About Micardis(R) (telmisartan)

Telmisartan is marketed inthe United States by Boehringer Ingelheim as MICARDIS(R) tablets. MICARDIS is indicated for the treatment of hypertension.

USE IN PREGNANCY

When used in pregnancy during the second and third trimesters, drugs that act directly on the renin-angiotensin system can cause injury and even death to the developing fetus. When pregnancy is detected, MICARDIS tablets should be discontinued as soon as possible (see WARNINGS, Fetal/Neonatal Morbidity and Mortality).

Thiazides cross the placental barrier and appear in cord blood. There is a risk of fetal or neonatal jaundice, thrombocytopenia, and possibly other adverse reactions that have occurred in adults.

MICARDIS is contraindicated in patients who are hypersensitive to any of their components.

In patients with an activated renin-angiotensin system, such as volume- and/or salt-depleted patients (e.g., those receiving high doses of diuretics), symptomatic hypotension may occur after initiation of MICARDIS therapy. This condition should be corrected prior to administration of MICARDIS tablets, and treatment should start under close medical supervision.

The most common adverse events occurring with MICARDIS tablets monotherapy at a rate of 1% and greater than placebo, respectively, were: upper respiratory tract infection (URTI) (7%, 6%), back pain (3%, 1%), sinusitis (3%, 2%), diarrhea (3%, 2%), and pharyngitis (1%, 0%).
