PURPOSE: To report a randomized study that investigated the safety (risk of major bleeds) and potential efficacy of edoxaban, an oral anticoagulant that targets the major components of arterial thrombi, to prevent loss of patency following endovascular treatment (EVT). METHODS: Between February 2012 and June 2014, 203 patients who underwent femoropopliteal EVT were randomized to receive aspirin plus edoxaban or aspirin plus clopidogrel for 3 months in the Edoxaban in Peripheral Arterial Disease (ePAD) study ( ClinicalTrials...

The significantly increased incidence of stroke and systemic embolisation caused by atrial fibrillation can be prevented by adequately adjusted anticoagulant therapy. Vitamin K antagonists effectively decrease the risk of thromboembolic events but this effect is influenced by many factors. The development of the new direct oral anticoagulant drugs (DOAC) in the last few years provided new opportunities for us to choose the suitable anticoagulant therapy. According to the results of the ENGAGE AF-TIMI 48 and ENSURE-AF multicenter, randomized trials, edoxaban, the recently introduced DOAC is equally effective as the traditional coumarin therapy, nevertheless, it ensures more tolerable anticoagulation for patients suffering from non-valvular atrial fibrillation...

Acute pulmonary embolism (PE) is a relatively common cardiopulmonary emergency that is a major cause of hospitalization and morbidity and is the primary cause of mortality associated with venous thromboembolism (VTE). During the last decade, one of the biggest changes in the management of PE has been the approval of four non-vitamin K antagonist oral anticoagulants (NOACs; apixaban, dabigatran, edoxaban and rivaroxaban) for the treatment of PE and deep vein thrombosis and secondary prevention of VTE. Areas covered: This article reviews the evolving management of PE in the NOAC era and addresses three fundamental questions: who should receive NOACs over conventional heparin/vitamin K antagonist regimens for the treatment of acute PE; whether patients should be treated as inpatients or outpatients; and how long patients should be treated to reduce the risk of recurrence? Expert commentary: The management of PE is changing...

BACKGROUND: Different target activated clotting times (ACTs) during atrial fibrillation (AF) ablation have been proposed. Moreover, relationships between initial bolus dose of heparin at the start of AF ablation in patients receiving edoxaban anticoagulation therapy and ACT are unclear. METHODS: Patients who received anticoagulation with uninterrupted warfarin (control; n = 120) or interrupted edoxaban (n = 120) on the morning of day of ablation were studied...

About 1.4 British million people are at risk of strokes due to non-valvular atrial fibrillation (AF) necessitating long-term anticoagulation. The vitamin K antagonist, warfarin, has a long half-life and narrow therapeutic range necessitating regular monitoring and is a common cause of iatrogenic hospital admission. Direct-acting oral anticoagulants (DOACs), dabigatran, rivaroxaban, apixaban and edoxaban are not required to have monitoring but are sensitive to changes in renal function and are associated with poorer adherence...

Venous thromboembolism (VTE), which includes both deep vein thrombosis and pulmonary embolism (PE), is a very common disorder with high risk for recurrence and is associated with significant morbidity and mortality. The non-vitamin K oral anticoagulants (NOACs), which include dabigatran, rivaroxaban, apixaban, and edoxaban, have been shown to be noninferior to conventional anticoagulant therapy for the prevention of recurrent VTE and are associated with more favorable bleeding risk. Evidence from the treatment of VTE with traditional therapy (low molecular weight heparin and vitamin K antagonists) implies that extended or indefinite treatment reduces risk of recurrence...

BACKGROUND: Factor Xa inhibitors and vitamin K antagonists (VKAs) are now recommended in treatment guidelines for preventing stroke and systemic embolic events in people with atrial fibrillation (AF). This is an update of a Cochrane review previously published in 2013. OBJECTIVES: To assess the effectiveness and safety of treatment with factor Xa inhibitors versus VKAs for preventing cerebral or systemic embolic events in people with AF. SEARCH METHODS: We searched the trials registers of the Cochrane Stroke Group and the Cochrane Heart Group (September 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (August 2017), MEDLINE (1950 to April 2017), and Embase (1980 to April 2017)...

Background: For the management of venous thromboembolism (VTE), providing anticoagulant therapy within the therapeutic range has been a major challenge, as conventional therapy with unfractionated heparin (UFH) and vitamin K antagonist (VKA) requires frequent laboratory monitoring and dose adjustment. Recently, fondaparinux and edoxaban are being used as beneficial alternatives to UFH and VKA. Methods: We evaluated the clinical course of symptomatic deep vein thrombosis (DVT) in patients who received the 3-month anticoagulation therapy with fondaparinux/edoxaban (Group A; n=40) in comparison with the findings from our previous experience of patients who received the fondaparinux/VKA combination (Group B; n=33)...

Atrial fibrillation (AF) is an established risk factor for a first or recurrent stroke. Despite proven efficacy in preventing stroke in patients with AF, warfarin is underused, partly due to safety concerns. Recent randomized trials have shown that non-vitamin K antagonist oral anticoagulants (NOACs) such as dabigatran (a direct thrombin inhibitor) and apixaban, edoxaban, and rivaroxaban (factor Xa inhibitors) are not only non-inferior or superior to warfarin but also demonstrate a decreased risk of cerebrovascular bleeding among patients with AF and moderate to high risk of stroke...

BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs) have gained increasing importance for stroke prevention in patients with non-valvular atrial fibrillation (AF). With changing prescription practice, among other factors, clinicians can expect to see rising numbers of patients with ischemic stroke and pre-existing NOAC therapy. Few data exist regarding a potential impact of NOAC on stroke severity and outcome. AIMS: To evaluate the impact of pre-admission NOAC therapy on ischemic stroke severity...

Edoxaban was extracted from human plasma by simple protein precipitation with acetonitrile, followed by quantitative determination using a liquid chromatography-mass spectrometry method. The recoveries of edoxaban and the internal standard (ticlopidine) from human plasma were higher than 85%, and the within- and between-day coefficients of variation were within 15%. The limit of quantification in human plasma was 1 ng/mL. The concentration of edoxaban in blood decreased at room temperature, but remained unchanged for 1 week at 4°C...

This report describes the case of a 66-year-old man with non-small cell lung cancer and venous thromboembolism (VTE). Unfractionated heparin (UFH) was initially used to control VTE before chemotherapy. However, switching UFH to warfarin or edoxaban, a novel oral anticoagulant (NOAC), failed. Chemotherapy was then administered to control the tumor which was thought to have been the main cause of VTE, which had been treated by UFH. After tumor shrinkage was achieved by chemotherapy, we were able to successfully switch from UFH to edoxaban...

This guidance document was prepared on behalf of the International Council for Standardization in Haematology (ICSH) for providing haemostasis-related guidance documents for clinical laboratories. This inaugural coagulation ICSH document was developed by an ad hoc committee, comprised of international clinical and laboratory direct acting oral anticoagulant (DOAC) experts. The committee developed consensus recommendations for laboratory measurement of DOACs (dabigatran, rivaroxaban, apixaban and edoxaban), which would be germane for laboratories assessing DOAC anticoagulation...

BACKGROUND: The optimal antithrombotic treatment after percutaneous coronary intervention (PCI) with stenting in patients with atrial fibrillation (AF) is unknown. In the ENGAGE AF-TIMI 48 trial, edoxaban was noninferior to a vitamin K antagonist (VKA) with respect to the prevention of stroke or systemic embolism and was associated with significantly lower rates of bleeding and cardiovascular death in patients with nonvalvular AF. The effects of edoxaban in combination with single- or dual-antiplatelet therapy in the setting of PCI are unexplored...
