The non-vitamin K antagonist oral anticoagulants (NOACs) include dabigatran, which inhibits thrombin, and apixaban, betrixaban, edoxaban, and rivaroxaban, which inhibit coagulation factor Xa. Although clinical studies of NOACs were conducted without antidotes, patient outcomes with major bleeding when receiving NOACs were no worse than those in patients treated with a vitamin K antagonist. Nonetheless, in patients with life-threatening bleeding or requiring urgent surgery, the capacity for rapid NOAC reversal is likely to increase patient safety...

Appropriate treatment of venous thromboembolism (VTE) is critical to minimizing long-term morbidity and mortality. The emergence of direct oral anticoagulants (DOACs) has provided clinicians with expanded therapeutic options for patients with VTE, and as a result, updated practice guidelines released by the American College of Chest Physicians favor DOACs over traditional anticoagulants, such as warfarin. The newest DOAC, betrixaban, received FDA approval in 2017, with an indication for VTE prophylaxis in hospitalized adults...

Following publication of our review article 4 years ago, there has been an uptake in the use of nonvitamin K oral antagonists, also known as direct oral anticoagulants. The most recent Xa inhibitors to receive approval are edoxaban, which has been approved for use in both atrial fibrillation and venous thromboembolism prevention and betrixaban, which has been approved in the USA for extended thromboprophylaxis in the medically ill population. Additional analyses of certain types of atrial fibrillation patients have now become available...

Hospitalized acute medically ill patients with a history of venous thromboembolism (VTE) are at increased risk for recurrent VTE. We characterized the efficacy and safety of betrixaban for prevention of recurrent VTE in these high risk patients. The APEX trial randomized 7513 acutely ill hospitalized medical patients at risk for developing VTE to receive either betrixaban for 35-42 days or enoxaparin for 10 ± 4 days to prevent VTE. This exploratory post-hoc analysis assessed the efficacy and safety of betrixaban versus enoxaparin among subjects with and without prior VTE...

Venous thromboembolism (VTE) is a significant healthcare burden with approximately 900,000 events annually in the United States, over half of which are healthcare-associated. This number is anticipated to double by 2050. Group prophylaxis strategies confined to the inpatient setting appear to have minimal impact on the reduction of post-discharge VTE in medically ill patients due to shortened lengths of stay and a heterogenous population that includes patients at low risk for VTE. In accordance with current guideline recommendations, very few (<5%) medically ill patients are discharged with extended prophylaxis, which potentially creates a clinical gap for at-risk patients as VTE risk has been shown to persist for up to 90 days...

Venous thromboembolism (VTE), comprising deep vein thrombosis and pulmonary embolism, is a serious clinical and public health concern. Hospitalization is a major risk factor for developing VTE. Hospital-associated events account for more than 50% of all cases of VTE. Heparins have demonstrated to be efficacious in the prevention of VTE in medically ill patients. Despite the demonstrated efficacy and safety of the available direct oral anticoagulants in the prevention and treatment of different thromboembolic conditions, their net benefit in the prevention of VTE in hospitalized medically ill patients has not been fully confirmed...

Direct oral anticoagulants (DOACs) are among the most effective options to prevent serious thromboembolic events in patients with atrial fibrillation. Coagulation assays are used to assess DOAC activity, but lack the possibility to quantify drugs with concurrent pharmacodynamic effect. We developed a selective multi-drug assay to analyze apixaban, betrixaban, dabigatran, edoxaban, edoxaban M4, and rivaroxaban with ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC/MS/MS) in plasma fulfilling all requirements of the FDA und EMA guidelines for bioanalytical method validation...

OBJECTIVE: Direct oral anticoagulants (DOACs) are recommended for the prevention of stroke or systemic embolism in nonvalvular atrial fibrillation. Dabigatran, rivaroxaban, apixaban, and edoxaban represent possible alternatives to warfarin in the setting of cardioversion. A literature review was conducted to evaluate the safety and efficacy of DOAC use pericardioversion. DATA SOURCES: A PubMed and MEDLINE search through August 2017 was conducted using the following search terms alone or in various combinations: dabigatran, rivaroxaban, apixaban, edoxaban, betrixaban, DOAC, NOAC, TSOAC, cardioversion...

BACKGROUND: Among patients hospitalized with acute heart failure (HF), the prognostic value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in short-term stroke prediction remains unclear. METHODS: In the APEX trial, 7513 patients hospitalized for an acute medical illness were randomized to receive either extended-duration betrixaban (80 mg once daily for 35-42 days) or standard-of-care enoxaparin (40 mg once daily for 10 ± 4 days) for venous thromboprophylaxis...

Competing risk methods are time-to-event analyses that account for fatal and/or nonfatal events that may potentially alter or prevent a subject from experiencing the primary endpoint. Competing risk methods may provide a more accurate and less biased estimate of the incidence of an outcome but are rarely applied in cardiology trials. APEX investigated the efficacy of extended-duration betrixaban versus standard-duration enoxaparin to prevent a composite of symptomatic deep-vein thrombosis (proximal or distal), nonfatal pulmonary embolism, or venous thromboembolism (VTE)-related death in acute medically ill patients (n = 7513)...

Betrixaban is a direct factor Xa inhibitor with a renal excretion of only approximately 5-7%. On June 23rd 2017, it became the first direct oral anticoagulant to receive Food and Drug Administration approval for the prevention of venous thromboembolism in acutely ill medical patients, and the first anticoagulant agent to be approved for extended-duration thromboprophylaxis after hospital discharge in this setting. Approval followed the results of the APEX trial, a phase III clinical trial comparing betrixaban (80 mg) administered for 35-42 days with enoxaparin (40 mg) administered for 10 ± 4 days...

BACKGROUND/AIMS: Venous thromboembolism (VTE) is the most common complication after major joint surgery. VTE can easily develop into pulmonary embolism (PE), leading to cardiopulmonary dysfunction or sudden death. We aimed to comprehensively analyse the thromboprophylactic drugs that are used to prevent thrombosis and reduce bleeding risk. METHODS: We searched the PubMed, EMBASE, and Cochrane databases for randomized controlled trials that evaluated the use of thromboprophylaxis after major joint surgery...

Essentials Anticoagulants prevent venous thromboembolism but may be associated with greater bleeding risks. Bivariate analysis assumes a non-linear relationship between efficacy and safety outcomes. Extended full-dose betrixaban is favorable over standard enoxaparin in bivariate endpoint. Clinicians must weigh efficacy and safety outcomes in decision-making on thromboprophylaxis. SUMMARY: Background Among acutely ill hospitalized medical patients, extended-duration thromboprophylaxis reduces the risk of venous thromboembolism (VTE), but some pharmacologic strategies have been associated with greater risks of major bleeding, thereby offsetting the net clinical benefit (NCB)...

BACKGROUND: Extended-duration betrixaban showed a significant reduction in venous thromboembolism in the APEX trial (Acute Medically Ill VTE Prevention With Extended Duration Betrixaban Study). Given the variable clinical impact of different efficacy and safety events, one approach to assess net clinical outcomes is to include only those events that are either fatal or cause irreversible harm. METHODS AND RESULTS: This was a post hoc analysis of the APEX trial-a multicenter, double-blind, randomized controlled trial comparing extended-duration betrixaban versus standard-of-care enoxaparin...

Data from recent randomized controlled trials indicate that the incidence of stroke among acutely ill medical patients is unexpectedly high and approximates 1% at 90 days. Preliminary data suggest that betrixaban may reduce ischemic stroke in patients without atrial fibrillation. There is an unmet demand for stroke risk stratification schemes targeting hospitalized medical patients. The prognostic value of biomarkers such as natriuretic peptides and D-dimer in predicting short-term stroke remains uncertain...
