Ingelheim, Germany, 6 November, 2012 – New real-world data reinforces the positive safety and efficacy profile of Pradaxa® (dabigatran etexilate) in clinical practice for the prevention of venous thromboembolism (VTE) in patients undergoing total knee or hip replacement.* Data presented today at the 2012 American Heart Association Scientific Sessions highlight that treatment with Pradaxa® was well tolerated and resulted in low incidence of major bleeding events irrespective of patient risk factors.1
VTE has been estimated to be the third most common cardiovascular disorder after coronary heart disease and stroke2. In Europe alone, it affects 1.5 million people and is responsible for 500.000 deaths annually.3,4 Anticoagulation therapy is effective in preventing VTE for patients undergoing total knee or total hip replacement and provides a three-fold reduction in the recurrence of VTE.5 In previous clinical trials, Pradaxa® was proven to be as effective as enoxaparin in this indication with a favourable safety profile and easier administration.6-8
The international observational study aimed to evaluate the safety and efficacy of dabigatran etexilate in a real-world clinical setting. The study involved 5,292 patients, 40 percent of whom had more than one potential risk factor† for increased bleeding and/or VTE. The results show:1
The low incidence of bleeding seen with Pradaxa® was consistent regardless of potential risk factors, such as chronic heart failure, history of VTE, chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), active smoking, concomitant ASA use, and coronary artery disease.
"These findings are very reassuring for both patients and physicians," said trial investigator Professor Simon Frostick, Institute of Translational Medicine, Faculty of Health & Life Sciences, University of Liverpool, United Kingdom. "They validate the strong safety and efficacy profile of Pradaxa® in this clinical setting, and support the results previously seen in clinical trials. These findings also demonstrate that Pradaxa® is a safe treatment option for VTE prevention in a broad range of patients, even for those at increased risk of bleeding or with a history of VTE."
Clinical experience with Pradaxa® is already well established and continues to grow. It equates to over one million patient-years in over 70 countries worldwide9, including both VTE prevention in patients undergoing total knee or total hip replacement and stroke prevention in patients with non-valvular atrial fibrillation, supporting the substantial benefits Pradaxa® offers to patients for both indications.
NOTES TO THE EDITORS
About venous thromboembolism
Venous thromboembolism (VTE) refers to a condition in which a blood clot (thrombus) forms in a vein. Most commonly, it develops in the deep veins of the leg or pelvis and is known as deep vein thrombosis (DVT). An embolism occurs if the clot, or a part of it, breaks off from the site where it forms and travels through the venous system. If the clot lodges in the lung a potentially fatal condition, pulmonary embolism (PE), occurs.
VTE is the third most common cardiovascular disorder after coronary heart disease and stroke,2 affecting approximately 1.5 million Europeans3 and 3 million Americans10 each year. In Europe, it kills more than twice as many people as AIDS, breast cancer, prostate cancer, and traffic accidents combined.4 In addition, up to half of people suffering from a DVT may develop the chronic post thrombotic syndrome (PTS) and 4% may develop chronic thromboembolic pulmonary hypertension.11,12
Given its prevalence, associated morbidity, mortality and chronic complications, VTE is a costly condition which puts a significant burden on healthcare systems and individuals. Annual costs of VTE are estimated to be more than $1.5 billion in the US alone.13
About dabigatran etexilate
Dabigatran etexilate is at the forefront of a new generation of oral anticoagulants/direct thrombin inhibitors (DTIs)14 targeting a high unmet medical need in the prevention and treatment of acute and chronic thromboembolic diseases.
Potent antithrombotic effects are achieved with direct thrombin inhibitors by specifically blocking the activity of thrombin (both free and clot-bound), the central enzyme in the process responsible for clot (thrombus) formation. In contrast to vitamin-K antagonists, which variably act via different coagulation factors, dabigatran etexilate provides effective, predictable and consistent anticoagulation with a low potential for drug-drug interactions and no drug-food interactions, without the need for routine coagulation monitoring or dose adjustment.
