Edoxaban (the free base of DU-176b) is a new, oral direct Factor Xa inhibitor. This is the first study to compare the hemostatic response to edoxaban, ximelagatran, and dalteparin in healthy, elderly adults. MATERIALS AND
In this open-label, active-controlled clinical trial, 40 adults (65-75years), were randomised to: oral edoxaban (60mg, twice-daily, 7 doses), subcutaneous dalteparin (5000IU, once-daily, 4 doses), oral ximelagatran (24mg, twice-daily, 7 doses) or no drug. Blood samples were taken before, and 1.5, 4, 12, 24, 72, 84, 96, 108, 120, and 144 hours after, the first dose. The primary outcomes were changes in thrombin-antithrombin complex, prothrombin fragment 1+2 and D-dimer, and adverse events. Additional biomarkers of coagulation, and endothelial cell and platelet activation were compared (ANOVA).
All subjects completed the study. Inhibition of thrombin generation lag time, peak, and constant velocity index were significantly greater, and extended for a longer period of time, following edoxaban administration, compared with dalteparin. We found that the traditional assay for anti-FXa activity was not appropriate for the new anticoagulants. Biomarker changes following edoxaban administration (including prolongation of prothrombin time) reflected inhibition of Factor Xa; there was no effect on platelet, tissue factor or endothelial activation. There were no clinically significant changes in primary outcomes. No serious adverse events were reported.
Oral administration of edoxaban resulted in effective Factor Xa and TG inhibition, and was well-tolerated. Studies are needed to confirm edoxaban (60mg daily) use in clinical practice.

In addition to platelet aggregation, coagulation activation is considered to be involved in arterial thrombosis. In this study, we determined antithrombotic effects of edoxaban, an oral factor Xa (FXa...
The purpose of this study is to compare the effect of increasing concentrations of direct anti-Xa oral anticoagulants (DOAC) apixaban-, edoxaban-, and rivaroxaban-enriched plasma samples on various pr...
Factor Xa inhibitor is a key drug in the coagulation cascade. Parenteral anticoagulation using low molecular weight heparin or fondaparinux is the recommended form of treatment for most patients prese...
To assess whether an oral direct factor Xa inhibitor (DiXaI) anticoagulant drug used at the low end of the recommended dose in people achieves presumed prophylactic plasma concentrations and does not ...
New oral anticoagulants (NOACs) have been developed in recent years and are increasingly used in clinical practice. Dabigatran is a direct thrombin (factor II) inhibitor while rivaroxaban, apixaban an...
This study will evaluate the establishment of anticoagulation ("re-anticoagulation") of subjects with edoxaban following reversal by PER977 and will identify a dose regimen of PER977 that ...
It is not uncommon that patients requiring dual antiplatelet therapy (DAPT) also need to be treated with oral anticoagulant therapy, such as those with atrial fibrillation (AF). Warfarin a...
The purpose of this study is to better understand if either dalteparin or tinzaparin is a better drug to use in dialysis patients on blood thinners who are at high risk of developing blood...
The purpose of this study is to evaluate tolerability of long-term treatment with ximelagatran compared to standard treatment with warfarin.
This study evaluates the optimal dosage and safety of Dalteparin when used as an anticoagulant for hemodialysis therapies.

A specificity protein transcription factor that regulates expression of a variety of genes including VASCULAR ENDOTHELIAL GROWTH FACTOR and CYCLIN-DEPENDENT KINASE INHIBITOR P27.
A COUP transcription factor that was originally identified as a homodimer that binds to a direct repeat regulatory element in the chicken albumin promoter. It is a transcription factor that plays an important role in EMBRYONIC DEVELOPMENT of the CENTRAL NERVOUS SYSTEM.
Activated form of factor VIII. The B-domain of factor VIII is proteolytically cleaved by thrombin to form factor VIIIa. Factor VIIIa exists as a non-covalent dimer in a metal-linked (probably calcium) complex and functions as a cofactor in the enzymatic activation of factor X by factor IXa. Factor VIIIa is similar in structure and generation to factor Va.
Activated form of factor XI. In the intrinsic pathway, Factor XI is activated to XIa by factor XIIa in the presence of cofactor HMWK; (HIGH MOLECULAR WEIGHT KININOGEN). Factor XIa then activates factor IX to factor IXa in the presence of calcium.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
