Rates, management and outcome of bleeding complications during edoxaban therapy in daily care – results from the DRESDEN NOAC REGISTRY

Abstract

Edoxaban is licensed in many countries around the world, following successful phase-III trials in stroke prevention in atrial fibrillation (SPAF) and treatment of venous thromboembolism (VTE), but at present, little is known about edoxaban-related bleeding complications in daily care. Using data from a prospective, non-interventional oral anticoagulation registry, we analysed rates, management and outcome of edoxaban-related bleeding. Between 1 October 2011 and 28 February 2019, 996 patients were enrolled in the edoxaban cohort and a total of 891 bleeding events were observed (53.2% ISTH minor, 41.9% clinically relevant non-major and 4.9% major bleeding events). In case of major bleeding, surgical or interventional treatment was performed in 25.0% and prothrombin complex concentrate was given in 2 cases. In the time-to-first-event analysis, 100-patient-year rates of major bleeding were 3.1/100 patient-years (95% CI 2.2–4.2). In the as-exposed analysis, case-fatality rates of edoxaban-associated bleeding leading to hospitalizations were 7.5% and 9.0% at days 30 and 90 post bleeding, respectively. Taken together, our data indicate that, in real life, rates of edoxaban-related major bleeding in line with rates observed in phase III trials and that bleeding pattern, management and outcome of these events are not different from those reported for other direct factor Xa inhibitors.Clinical Trial Notation: Dresden NOAC Registry - ClinicalTrials.gov Identifier NCT01588119
