An antidote to factor Xa inhibitors can safely reverse the anticoagulant effect of apixaban in healthy volunteers, results of the ANNEXA-A study suggest. The first part of this study showed that a bolus of the antidote, andexanet alfa, was effective. And none of the volunteers had serious adverse events, thrombotic events, or... [Read Article]

The antihemophilic factor turoctocog alfa is safe and effective long-term, according to interim data from the phase 3 guardian 2 trial. With more than 4 years of safety data, researchers have found turoctocog alfa to be well-tolerated in patients with hemophilia A. The median annualized bleeding rate for patients on prophylactic treatment was... [Read Article]

Drug reverses anticoagulant effect of dabigatran



Interim results of a phase 3 study suggest idarucizumab, a humanized antibody fragment, can reverse the anticoagulant effect of dabigatran in real-world situations. In the RE-VERSE AD trial, idarucizumab normalized diluted thrombin time (dTT) and ecarin clotting time (ECT) in a majority of patients with uncontrolled or life-threatening bleeding complications and most patients who required emergency surgery or an...

Bridge anticoagulant therapy appears to be unnecessary in patients with atrial fibrillation (AFib) undergoing elective surgery, according to researchers. In the BRIDGE study, AFib patients who stopped all anticoagulant therapy before elective surgery had no higher risk of thrombosis and a lower risk of major bleeding than patients who were given bridge therapy...
