• Worldwide RE-DUAL PCITM to enroll up to 8,500 patients with atrial fibrillation who have received a coronary stent1
• Data intended to help understand how to reduce blood clot risk and minimise bleeding risk in this patient population
• Study is cooperatively conducted by the Harvard Clinical Research Institute and Boehringer Ingelheim

Ingelheim, Germany, 19 August, 2014 – Boehringer Ingelheim today announces that the first patients have been enrolled in the company’s new international phase III study, RE-DUAL PCI™.1 The study will evaluate the efficacy and safety of the oral anticoagulant dabigatran etexilate in patients with an irregular heartbeat called non-valvular atrial fibrillation (AF), who have undergone a percutaneous coronary intervention (PCI) with stent placement to widen their blocked coronary arteries.2 RE-DUAL PCITM aims to advance medical knowledge and guide future antithrombotic treatment choice for greatest patient benefit. It addresses the need for innovative new treatment regimens to improve patient prognosis.

AF is associated with a risk of stroke caused by blood clots from the heart.3 PCI, also known as angioplasty, is a medical procedure where a stent (a small mesh tube) is used to widen the arteries of the heart to restore or improve blood flow in patients with coronary artery disease.4 However the procedure is also associated with a risk of serious complications caused by blood clots, including stroke and other major adverse cardiac events.5,6 Patients with AF who undergo PCI are thus at special risk of these complications. To prevent them, patients receive antithrombotic therapy. Current standard care is linked to an increased risk of bleeding, because it currently involves taking three antithrombotic treatments together, one of them an anticoagulant.7

"Currently there are limited data about appropriate anticoagulation treatment in patients with AF undergoing PCI," said Professor Christopher Cannon, RE-DUAL PCITM Lead Investigator and Executive Director, Cardiometabolic Trials, Harvard Clinical Research Institute."We expect this study to provide data that can help us better understand how to prevent stroke and stent thrombosis while at the same time minimising bleeding risk in this especially vulnerable patient population," said Cannon, who also is a cardiologist at Brigham and Women’s Hospital in Boston and a Professor of Medicine, Harvard Medical School.

The RE-DUAL PCI™ study will compare the efficacy and safety of dual antithrombotic therapy with dabigatran etexilate (110mg or 150mg twice daily) plus clopidogrel or ticagrelor versus the currently recommended standard triple antithrombotic therapy regimen with warfarin (INR 2.0 – 3.0) plus clopidogrel or ticagrelor plus acetylsalicylic acid.2 The study will enroll approximately 8,500 patients at 700 sites in over 40 countries around the globe.1 Boehringer Ingelheim is conducting the study cooperatively with the Harvard Clinical Research Institute.

"Boehringer Ingelheim is confident in the ability of dabigatran etexilate to safely reduce the risk of thromboembolic events when used as directed and is committed to expanding the scientific knowledge of dabigatran use in AF patients who undergo significant procedures for their cardiac conditions," said Professor Klaus Dugi, Chief Medical Officer, Boehringer Ingelheim. "We look forward to the continuing enrollment of patients in RE-DUAL PCI™ and expect to have full results in 2017."

RE-DUAL PCI™ is part of Boehringer Ingelheim’s extensive clinical trial program, RE-VOLUTION™. With the recently announced RE-CIRCUIT™ and RE-SPECT ESUS™ studies, the entire programme will include 15 clinical trials involving over 60,000 patients in more than 100 countries globally.2,8-20


About PCI
PCI, also known as angioplasty, is a medical intervention where stents are used to widen arteries of the heart.4 This intervention to restore or improve blood flow to the heart muscle is frequently undertaken in patients with an irregular heartbeat (AF) if they also have coronary artery disease.4,20 Worldwide, over one million AF patients may require the procedure each year.21

Patients with AF who undergo PCI with stenting are at increased risk of serious complications caused by blood clots, including stroke, systemic embolism, heart attacks, blood clots on the stents and even death.5,6 Long-term antithrombotic therapy is required to decrease patients’ risk of suffering blood clots and their consequences.


Randomized Evaluation of DUAL Therapy with Dabigatran vs. Triple Therapy with Warfarin in Patients with NVAF that have Undergone PCI with Stenting

RE-DUAL PCITM will enroll approximately 8,500 patients at 700 sites in over 40 countries around the globe.1

The study has two primary endpoints, a composite efficacy endpoint and a safety endpoint. The composite efficacy endpoint is the time to death or first thrombotic event (all death, myocardial infarction, stroke or systemic embolism).2 The safety endpoint is the time to first major bleeding event, as defined by the International Society on Thrombosis and Haemostasis (ISTH).2

The estimated duration of the trial is 30 months.1 Because the trial protocol requires that the last patient entering the study receives at least six months of treatment, the earliest enrolled patients could be followed up to 30 months, the estimated duration of this event-driven trial.

About Pradaxa® (dabigatran etexilate)
Clinical experience of Pradaxa® (dabigatran etexilate) exceeds that of all other novel oral anticoagulants, equating to over 3 million patient-years in all licensed indications worldwide. Pradaxa® has been in the market for more than 6 years and is approved in over 100 countries.1

Currently approved indications for Pradaxa® are:22,23

  • 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 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.22,24 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
