Use and Outcomes Associated with Bridging During Anticoagulation Interruptions in Patients with Atrial Fibrillation: Findings from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF)

Circulation
This study noted that bridging anticoagulation is used in a-quarter of anticoagulation interruptions and is linked to higher risk for bleeding (5.0 vs. 1.3%, OR 3.84, p<0.0001) and adverse events (13 vs. 6.3%; OR 1.94, p=0.0001) vs. non-bridging.

Factor XI Antisense Oligonucleotide for Prevention of Venous Thrombosis

New England Journal of Medicine

RCT in 300 patients found FXI-ASO was non-inferior (200mg OD) or superior (300mg OD) to enoxaparin 40mg OD daily in prevention of VTE in patients undergoing total knee arthroplasty (VTE in 27%, 4% and 30%; and bleeding in 3%, 3%, and 8%; respectively).

Conference report: Phase I study reports idarucizumab reverses anticoagulant effects of dabigatran in middle-aged, elderly and renally impaired volunteers

Biospace Inc.

Administration of idarucizumab in these groups (n=46) resulted in immediate, complete and sustained reversal of the anticoagulation effects of dabigatran. Anticoagulation was restored when volunteers were re-dosed with dabigatran 24 hours after idarucizumab was administered.
