RIDGEFIELD, Conn., Oct. 16, 2015 /PRNewswire/ — Boehringer Ingelheim Pharmaceuticals, Inc. today announced the U.S. Food and Drug Administration (FDA) granted approval of Praxbind® (idarucizumab). PRAXBIND is indicated for patients treated with Pradaxa® (dabigatran etexilate mesylate), when reversal of the anticoagulant effects of dabigatran is needed for emergency surgery/urgent procedures or in life-threatening or uncontrolled bleeding. This indication is approved under accelerated approval based on a reduction in unbound dabigatran and normalization of coagulation parameters in healthy volunteers. Continued approval for this indication may be contingent upon the results of an ongoing cohort case series study.
“We are very pleased to offer PRAXBIND, the first specific reversal agent for a novel oral anticoagulant, now approved by the FDA,” said Sabine Luik, MD, senior vice president, Medicine & Regulatory Affairs, Boehringer Ingelheim Pharmaceuticals, Inc. “With this approval, Boehringer Ingelheim is again leading the evolution of anticoagulation care, as we did with the introduction of PRADAXA. While we anticipate that PRAXBIND will be rarely used in clinical practice, the availability of a specific reversal agent has the potential to give physicians and patients added assurance in choosing PRADAXA.”
The FDA granted PRAXBIND Breakthrough Therapy Designation and the application received Priority Review. PRAXBIND was approved under an Accelerated Approval Pathway. The application included data from healthy volunteers as well as results from an interim analysis of the RE-VERSE AD™ trial (NCT02104947). In the studies, the reversal effects of PRAXBIND were evident immediately, within minutes after administration of 5 grams of PRAXBIND. No procoagulant effect was observed after the administration of PRAXBIND.
There are serious risks to consider when treating patients with PRAXBIND, including warnings and precautions for thromboembolic risk, re-elevation of coagulation parameters, hypersensitivity reactions and risks of serious adverse reactions in patients with hereditary fructose intolerance due to sorbitol excipient. The most frequently reported adverse reactions (≥5%) in PRAXBIND-treated healthy volunteers was headache and in the Phase III RE-VERSE AD study were hypokalemia, delirium, constipation, pyrexia and pneumonia.
Please see more complete details of these risks in the “About PRAXBIND” section.
“The emergence of novel oral anticoagulants, or NOACs, marked a significant advancement in anticoagulation care. While general management strategies for NOAC-related bleeding are available, until today, there was no option for specific and immediate reversal of the anticoagulant effect of a NOAC in a patient in rare emergencies where speed matters, such as life-threatening bleeding or the need to quickly perform surgery or interventions,” said Dr. Charles Pollack, lead investigator of RE-VERSE AD, Professor of Emergency Medicine, Sidney Kimmel Medical College, Thomas Jefferson University in Philadelphia. “The availability of PRAXBIND now provides a unique option for reversing anticoagulation in patients taking PRADAXA.”
PRAXBIND will be available from major U.S. hospital pharmacy distributors. Boehringer Ingelheim is committed to making PRAXBIND available as quickly as possible.
About the PRAXBIND Clinical Trial Program
PRAXBIND was discovered and developed by Boehringer Ingelheim scientists. The research program was initiated in 2009, before PRADAXA was launched in the U.S. in 2010.
The company completed three phase I trials of PRAXBIND in healthy volunteers, and included these data in the PRAXBIND biologics license application (BLA) it submitted to the U.S. Food and Drug Administration.
Boehringer Ingelheim is continuing to evaluate PRAXBIND in RE-VERSE AD™, a phase III global study that includes patients taking PRADAXA who have uncontrolled bleeding or require emergency procedures. The study is the first of its kind in patients, and has been underway since May 2014, enrolling patients in more than 35 countries. Data from an interim analysis from RE-VERSE AD was also included in the PRAXBIND application.

IMPORTANT SAFETY INFORMATION ABOUT PRADAXA
PRADAXA is contraindicated in patients with:
WARNINGS & PRECAUTIONS
Increased Risk of Thrombotic Events after Premature Discontinuation
Premature discontinuation of any oral anticoagulant, including PRADAXA, in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. If PRADAXA is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant.
Risk of Bleeding
Reversal of Anticoagulant Effect: There is a specific agent that reverses the anticoagulation effect of PRADAXA in the rare event of an emergency. Hemodialysis can remove dabigatran; however clinical experience for hemodialysis as a treatment for bleeding 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.
Thromboembolic and Bleeding Events in Patients with Prosthetic Heart Valves
The use of PRADAXA is contraindicated in patients with mechanical prosthetic valves due to a higher risk for thromboembolic events, especially in the post-operative period, and an excess of major bleeding for PRADAXA vs. warfarin. Use of PRADAXA for the prophylaxis of thromboembolic events in patients with AFib in the setting of other forms of valvular heart disease, including bioprosthetic heart valve, has not been studied and is not recommended.
Effect of P-gp Inducers & Inhibitors on Dabigatran Exposure
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.
Reduction of Risk of Stroke/Systemic Embolism in NVAF
Treatment and Reduction in the Risk of Recurrence of DVT/PE
The most serious adverse reactions reported with PRADAXA were related to bleeding.
Drug hypersensitivity reactions were reported in ≤ 0.1% of patients receiving PRADAXA.
Other Measures Evaluated
In NVAF patients, a higher rate of clinical MI was reported in patients who received PRADAXA (0.7/100 patient-years for 150 mg dose) than in those who received warfarin (0.6).
