Ingelheim, Germany, 1 September 2014 – Five years on from the first breakthrough presentation of the pivotal RE-LY® clinical trial of Pradaxa® (dabigatran etexilate) for the prevention of stroke in non-valvular atrial fibrillation (NVAF),4 extensive clinical trial and real-world data support Pradaxa® in various indications.1-12 Boehringer Ingelheim continues to grow the evidence base for Pradaxa® to improve care for patients at risk of blood clots and today announces the initiation of Phase III of the GLORIATM-AF registry program in North America and in Europe. During this final phase of the registry program, data on the overall safety and effectiveness of antithrombotic treatments will be collected.13

"The body of evidence supporting Pradaxa®, based on clinical trials, analyses of large real-world databases and different regulatory assessments since the RE-LY® trial was first presented, is both robust and consistent" said Professor Jörg Kreuzer, Therapeutic Area Head Cardiovascular Medicine, Boehringer Ingelheim. "And we will continue our research both in clinical trials and in clinical practice to further strengthen this evidence base for Pradaxa® to support the confident use of our treatment by physicians and patients, so that patients can receive the best possible care."

The extensive research programme by Boehringer Ingelheim for Pradaxa®, aimed at deepening the science behind effective clot prevention and providing support for everyday patient management, will eventually include over 100,000 patients.4-19 The research programme covers both clinical studies and analyses of everyday clinical practice and includes the GLORIA™-AF registry, the recently announced RE-CIRCUIT™, RE-DUAL PCI™ and RE-SPECT ESUS™* studies for Pradaxa®†, and the RE-VERSE AD™ trial to investigate the antidote idarucizumab‡ in the clinical setting in patients taking Pradaxa®.4-19

Beyond the Boehringer Ingelheim research programme, independent studies have been conducted that support the efficacy and safety profile of Pradaxa®.1-3 The U.S. Food and Drug Administration recently reinforced the favourable efficacy and safety profile of Pradaxa® based upon a large analysis of Medicare data.§3 The analysis involved 134,000 patients, 65 years or older and its findings were consistent with results of the clinical RE-LY® trial that supported the global approval of Pradaxa® for stroke prevention in non-valvular atrial fibrillation.3-5 The study found that, among new users of blood-thinning drugs, Pradaxa® was associated with a similar risk of myocardial infarction (MI) compared to warfarin and an increased risk of major gastrointestinal (GI) bleeding, just like in RE-LY®.3-5 But most importantly, the study also showed that with Pradaxa®, there was a lower risk of clot-related strokes, bleeding in the brain, and death compared to warfarin treatment.3

*Dabigatran etexilate is not approved in any country for patients with ESUS.
†The new trial announcements have not received indication approvals.
‡Idarucizumab is the recommended International Nonproprietary Name (INN). The antidote is still under investigation and has not yet been approved for clinical use.
§In the United States, the licensed doses for dabigatran etexilate are 150mg twice daily and 75mg twice daily for the prevention of stroke and systemic embolism in adult patients with non-valvular AF.20 The dose of 75mg twice daily is not authorised in Europe for this indication.21

About RE-VERSE AD™
RE-VERSE AD™, a global patient study, is now underway to investigate idarucizumab in the clinical setting in patients taking Pradaxa®. This is the first time that an antidote under development for a novel oral anticoagulant is investigated in a pivotal patient study. The first study sites in Europe have been initiated, and more sites and countries will follow during the course of 2014.19

About GLORIA™-AF
GLORIA™-AF is a large, multinational, prospective registry program designed to investigate patient characteristics influencing choice of antithrombotic treatment for stroke prevention in atrial fibrillation (AF). The registry program will use outcome data from clinical practice to provide valuable insights on the overall safety and effectiveness of antithrombotic treatments.13

The latest data from Phase II of GLORIA™-AF were presented in a Registry Hot Line session at the ESC Congress 2014. The results from the first 10,000 patients in Phase II showed that even despite the availability of the novel oral anticoagulants as alternatives to warfarin, there are still too many patients diagnosed with non-valvular atrial fibrillation (NVAF) at risk of stroke who remain undertreated and do not receive adequate treatment to protect them from stroke. While the data are encouraging, and show in some regions (North America and Europe) increasing uptake of NOACs and preference over vitamin k antagonists (VKAs, such as warfarin), high proportions of patients remain undertreated with acetylsalicylic acid (ASA) only, or receive no treatment. This is most pronounced in Asia, but also prevalent in North America.22

About Pradaxa® (dabigatran etexilate)
Clinical experience of Pradaxa® (dabigatran etexilate) equates to 2.4 million patient-years in all licensed indications worldwide.23 Pradaxa® has been in the market for more than 6 years and is approved in over 100 countries.

Currently approved indications for Pradaxa® are:20,21

  • Prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation and a risk factor for stroke
  • Primary prevention of venous thromboembolic events in patients undergoing elective total hip replacement surgery or total knee replacement surgery
  • Treatment of DVT and PE and the prevention of recurrent DVT¥ and recurrent PE¥ in adults

Pradaxa®, a direct thrombin inhibitor (DTI), was the first widely approved drug in a new generation of direct oral anticoagulants, available to target a high unmet medical need in the prevention and treatment of acute and chronic thromboembolic diseases.21,24 Potent antithrombotic effects are achieved with direct thrombin inhibitors by specifically blocking the activity of thrombin, the central enzyme in the process responsible for clot (thrombus) formation.25 In contrast to vitamin-K antagonists, which variably act via different coagulation factors, Pradaxa® provides effective, predictable and reproducible anticoagulation with a low potential for drug-drug interactions and no drug-food interactions, without the need for routine coagulation monitoring or mandatory dose adjustment.24,26
