RIDGEFIELD, Conn., Oct. 30, 2012 /PRNewswire/ -- Boehringer Ingelheim will present data from 16 abstracts at the American Heart Association's (AHA) Scientific Sessions in Los Angeles from November 3 to 7, 2012, including data on Pradaxa® (dabigatran etexilate mesylate) capsules and data evaluating patients with non-valvular atrial fibrillation (NVAF). These data reinforce BI's commitment to adding to the scientific body of evidence for PRADAXA and stroke prevention in NVAF.
Highlighted at the AHA meeting will be interim results from RELY-ABLE®, a long-term extension trial of the pivotal RE-LY® study, which will be featured in the Clinical Science: Special Reports presentations on November 7.
In addition, a RE-LY sub-analysis that examined "ischemic stroke equivalents," a method used to integrate ischemic and bleeding events, that compared a weighted benefit of two doses of dabigatran with each other and warfarin, will be presented on November 5. A different RE-LY sub-analysis that examined patient characteristics and outcomes in patients with NVAF who had diabetes compared to those without diabetes will be presented on November 4.

About Pradaxa® (dabigatran etexilate mesylate) Capsules
Indications and Usage
PRADAXA is indicated to reduce the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation.
IMPORTANT SAFETY INFORMATION ABOUT PRADAXA
PRADAXA is contraindicated in patients with active pathological bleeding and patients with a known serious hypersensitivity reaction (e.g., anaphylactic reaction or anaphylactic shock) to PRADAXA.
WARNINGS & PRECAUTIONS
Risk of Bleeding
- PRADAXA increases the risk of bleeding and can cause significant and, sometimes, fatal bleeding. Promptly evaluate any signs or symptoms of blood loss, such as a drop in hemoglobin and/or hematocrit or hypotension. Discontinue PRADAXA in patients with active pathological bleeding.
- Risk factors for bleeding include medications that increase the risk of bleeding (e.g., anti-platelet agents, heparin, fibrinolytic therapy, and chronic use of NSAIDs). PRADAXA's anticoagulant activity and half-life are increased in patients with renal impairment.
- A specific reversal agent for dabigatran is not available. Dabigatran can be dialyzed (removal of about 60% of drug over 2-3 hours) but data supporting this is limited. Activated prothrombin complex concentrates, recombinant Factor VIIa, or concentrates of factors II, IX or X may be considered but their use has not been evaluated. Protamine sulfate and vitamin K are not expected to affect dabigatran anticoagulant activity. Consider administration of platelet concentrates where thrombocytopenia is present or long-acting antiplatelet drugs have been used.
Temporary Discontinuation of PRADAXA
Discontinuing PRADAXA for active bleeding, elective surgery, or invasive procedures places patients at an increased risk of stroke. Minimize lapses in therapy.
Effect of P-gp Inducers & Inhibitors on Dabigatran Exposure
The concomitant use of PRADAXA with P-gp inducers (e.g., rifampin) reduces exposure to dabigatran and should generally be avoided. P-gp inhibition and impaired renal function are major independent factors in increased exposure to dabigatran. Concomitant use of P-gp inhibitors in patients with renal impairment is expected to increase exposure of dabigatran compared to either factor alone.
- For patients with moderate renal impairment (CrCl 30-50 mL/min), consider reducing the dose of PRADAXA to 75 mg twice daily when dronedarone or systemic ketoconazole is coadministered with PRADAXA.
- For patients with severe renal impairment (CrCl 15-30 mL/min), avoid concomitant use of PRADAXA and P-gp inhibitors.
In the pivotal trial comparing PRADAXA to warfarin, the most frequent adverse reactions leading to discontinuation of PRADAXA were bleeding and gastrointestinal (GI) events. PRADAXA 150 mg resulted in a higher rate of major GI bleeds and any GI bleeds compared to warfarin. In patients >75 years of age, the risk of major bleeding may be greater with PRADAXA than with warfarin. Patients on PRADAXA 150 mg had an increased incidence of GI adverse reactions. These were commonly dyspepsia (including abdominal pain upper, abdominal pain, abdominal discomfort, and epigastric discomfort) and gastritis-like symptoms (including GERD, esophagitis, erosive gastritis, gastric hemorrhage, hemorrhagic gastritis, hemorrhagic erosive gastritis, and GI ulcer). Drug hypersensitivity reactions were reported in <0.1% of patients receiving PRADAXA.
Other Measures Evaluated
In the pivotal trial, a higher rate of clinical myocardial infarction was reported in patients who received PRADAXA (0.7 per 100 patient-years for 150 mg dose) than in those who received warfarin (0.6).
