The Non-Vitamin K Antagonist Oral Anticoagulants in Heart Disease: Section V-Special Situations.
Non-vitamin K antagonist oral anticoagulants (NOACs) include dabigatran, which inhibits thrombin, and apixaban, betrixaban, edoxaban and rivaroxaban, which inhibit factor Xa. In large clinical trials comparing the NOACs with the vitamin K antagonist (VKA) warfarin, dabigatran, apixaban, rivaroxaban and edoxaban were at least as effective for stroke prevention in atrial fibrillation and for treatment of venous thromboembolism, but were associated with less intracranial bleeding. In addition, the NOACs are more convenient to administer than VKAs because they can be given in fixed doses without routine coagulation monitoring. Consequently, the NOACs are now replacing VKAs for these indications, and their use is increasing. Although, as a class, the NOACs have a favourable benefit-risk profile compared with VKAs, choosing among them is complicated because they have not been compared in head-to-head trials. Therefore, selection depends on the results of the individual trials, renal function, the potential for drug-drug interactions and preference for once- or twice-daily dosing. In addition, several 'special situations' were not adequately studied in the dedicated clinical trials. For these situations, knowledge of the unique pharmacological features of the various NOACs and judicious cross-trial comparison can help inform prescription choices. The purpose of this position article is therefore to help clinicians choose the right anticoagulant for the right patient at the right dose by reviewing a variety of special situations not widely studied in clinical trials.

Direct Oral Anticoagulants in the Prevention and Treatment of Venous Thromboembolism in Patients with Cancer: New Insights from Randomized Controlled Trials.
Cancer accounts for 20% of all venous thromboembolism (VTE) worldwide and cancer patients are at four- to sevenfold increased risk of thrombosis compared to non-cancer patients. VTE is also a morbid complication of cancer and its incidence is rising. Thrombosis is also a second leading cause of death in cancer patients. The standard of care management for the prevention and treatment of cancer-associated thrombosis (CAT) remains the administration of low-molecular-weight heparins (LMWHs). In the last decade, five direct oral anticoagulants (DOACs), dabigatran, rivaroxaban, apixaban, edoxaban and betrixaban, have been approved for the treatment and prevention of VTE in the general patient population. In this review, we discuss the results of the already published clinical trials with DOACs in the treatment of CAT and the ongoing clinical trials with DOACs in the prevention and treatment of CAT.

Management of Elective Surgery and Emergent Bleeding with Direct Oral Anticoagulants.
The purpose of this review was to offer practical management strategies for when patients receiving direct oral anticoagulants require elective surgery or present with bleeding complications.. Clinical practice guidelines are now available on the timing of periprocedural interruption of treatment with the newer direct oral anticoagulants based on their pharmacodynamics and pharmacokinetics and based on findings from cohort studies and clinical trials. An antibody that reverses the effects of dabigatran is now available, and a factor Xa decoy is being developed as an antidote to apixaban, betrixaban, edoxaban, and rivaroxaban. The timing of interruption of direct oral anticoagulants for elective surgery is based on multiple factors, including pharmacologic properties and interactions, the patient's renal function, and the type of planned surgery. There is little role for low-molecular-weight heparin bridging. Idarucizumab is the treatment of choice for dabigatran-related life-threatening bleeding, while andexanet alfa is being developed to reverse factor Xa inhibitors.

Advances in oral anticoagulation therapy - What's in the pipeline?
Approximately 900,000 people are affected by some sort of venous thromboembolic (VTE) event every year in the United States. VTE diagnosis used to mean treatment with medications that required routine lab monitoring for safety and efficacy. Activated factor X (FXa) inhibition has emerged as a convenient pathway for management of VTE and currently three FXa inhibitors are available for anticoagulation management - rivaroxaban, apixaban, and edoxaban. Continued development of medications utilizing this pathway may offer advantages via novel pharmacokinetic or pharmacodynamic properties that may minimize the adverse effects associated with traditional anticoagulant therapy. This review summarizes the available information regarding pharmacokinetic, pharmacodynamic, and early safety and efficacy data for three factor Xa inhibitors being developed - darexaban, betrixaban and nokxaban. The studies reviewed in this article suggests that three newer agents possess the potential for promise based on early phase I and II trials.

Reversal of anticoagulants: an overview of current developments.
Several new anticoagulants have entered the clinical arena or are under clinical development. These drugs include indirect (fondaparinux) and direct oral factor Xa inhibitors (rivaroxaban, apixaban, edoxaban, betrixaban), and the direct thrombin inhibitor dabigatran. Especially the oral direct FXa and FIIa inhibitors overcome many of the shortcomings of heparins and vitamin K antagonists (VKAs). They are administered orally at a fixed dose; regular monitoring is not necessary; interaction with other drugs or nutrition occur less than with VKAs and they are at least as effective as VKAs for most indications tested. They are associated with about 50 % less intracranial bleeding than VKAs. Nevertheless, they are still associated with bleeding complications. Bleeding can occur spontaneously or as a result of trauma or urgent surgery. In such situations rapid reversal of the anticoagulant effect is highly desirable. For unfractionated heparin protamine, and for VKAs prothrombin complex concentrates are available as specific antidotes. Under clinical development are: for the direct and indirect FXa inhibitors a modified recombinant FXa (andexanet alpha), which lacks enzymatic activity; and for dabigatran a Fab fragment of a monoclonal antibody (idarucizumab). In addition a small molecule (aripazine) has entered phase I clinical trials, which seems to inhibit nearly all anticoagulants but VKAs and argatroban. This review summarises the current options and strategies in development to antagonise anticoagulants with a focus on the status of the development of antidotes for the oral direct FXa and FIIa inhibitors.

[Pharmacologic and clinical characteristics of direct inhibitors of factor Xa: rivaroxaban, apixaban, edoxaban and betrixaban].
Heparins and vitamin K antagonists (VKA) used commonly are the standard treatment of venous and arterial thromboses. They are very efficient and safe, but have some limitations: iatrogenicity, laboratory monitoring, parenteral use for heparins and fondaparinux. Nowadays, four new inhibitors of factor Xa are used orally (rivaroxaban, apixaban, edoxaban, betrixaban), and they are at least as efficient as heparins and vitamin K antagonists. The objective is to substitute these indirect inhibitors of factor Xa (heparins, low molecular weight heparins and fondaparinux) in the prevention of venous and arterial thromboembolic episodes. The new direct inhibitors do not require routine laboratory monitoring of blood coagulation. They inhibit the extrinsic and the intrinsic pathways of blood coagulation. Rivaroxaban and apixaban are efficacious and safe in the prevention of cerebral infarcts in patients with non-valvular fibrillation. Apixaban is another direct inhibitor of factor Xa used orally which is developed in the same indications as rivaroxaban. Edoxaban and betrixaban are also in development. The objective of this work is to study the pharmacodynamic, pharmacokinetic, the efficacy and safety of these four oral direct factor Xa inhibitors.

Pharmacology and laboratory testing of the oral Xa inhibitors.
New oral factor Xa inhibitors are intended to progressively substitute the oral vitamin K antagonists and parenteral indirect inhibitors of factor Xa in the prevention and treatment of venous and arterial thromboembolic episodes. This article focuses on the main clinical studies and on biological measurements of new oral factor Xa inhibitors, and addresses several safety issues. These newer agents do not require any routine laboratory monitoring of blood coagulation; however, biological tests have been developed in order to assess the plasma concentration of these drugs in several clinical settings. This article reviews these 4 oral direct factor Xa inhibitors.

[Thromboembolic prophylaxis 2011: is warfarin on the wane?].
Warfarin has been the effective treatment in the prophylaxis of cardioembolism, in particular in patients with atrial fibrillation, for more than 50 years. Nevertheless, many patients with atrial fibrillation are not currently treated because of the numerous limits of oral anticoagulation and in those treated the quality of anticoagulation is often poor. Novel oral anticoagulant drugs, the direct thrombin antagonist dabigatran and factor Xa inhibitors such as rivaroxaban, apixaban, edoxaban, and betrixaban are more predictable and convenient anticoagulants in comparison with warfarin, mainly because of the non-requirement of regular laboratory monitoring and dose adjustments. Current data from phase III clinical trials are available for dabigatran, rivaroxaban and apixaban, which show to be at least noninferior in efficacy to warfarin for the prevention of stroke in patients with atrial fibrillation. This review focuses on the potential of novel anticoagulants to replace warfarin in patients with atrial fibrillation. Also the place in therapy and the potential limitations of the new agents in clinical practice represent important issues to be considered. The promise of new oral anticoagulants gives us the hope that warfarin will finally be replaced in a near future, but more importantly that anticoagulant undertreatment of atrial fibrillation will be partially overcome.

Oral factor Xa inhibitors for the prevention of stroke in atrial fibrillation.
Prevention of stroke and systemic emboli is paramount in the management of atrial fibrillation. Although warfarin is the predominant anticoagulant used in patients with atrial fibrillation, it has significant limitations that have impeded appropriate use of stroke prophylaxis in eligible patients with atrial fibrillation. Consequently, much research has been focused on finding an alternative to warfarin. We review the potential alternatives in development and evaluate the current evidence concerning their safety and efficacy.. Oral direct factor Xa inhibitors are potentially well tolerated and effective replacements for warfarin. These agents do not require cofactors and offer selective inhibition at a critical step of amplification in the coagulation cascade. Multiple direct anti-factor Xa agents are currently undergoing evaluation in phase I, II, and III trials. Early results suggest that these novel anticoagulants have favorable pharmacokinetic and pharmacodynamic profiles with minimal-to-no requirements for therapeutic monitoring. Two direct factor Xa inhibitors are emerging from phase II trials (betrixaban and YM150) and three are being evaluated in phase III trials (apixaban, edoxaban, and rivaroxaban) for the prevention of stroke and systemic emboli in patients with atrial fibrillation. The phase III trials of apixaban and rivaroxaban have completed enrollment and are in the follow-up phase.. Given the growing population of patients with atrial fibrillation, there is a great interest in finding new therapies for oral anticoagulation. The direct factor Xa inhibitors may offer several promising alternatives to warfarin therapy.

New anticoagulants for atrial fibrillation.
Atrial fibrillation is already the most common clinically significant cardiac arrhythmia and a common cause of stroke. Vitamin K antagonists are very effective for the prevention of cardioembolic stroke but have numerous limitations that limit their uptake in eligible patients with AF and reduce their effectiveness in treated patients. Multiple new anticoagulants are under development as potential replacements for vitamin K antagonists. Most are small synthetic molecules that target factor IIa (e.g., dabigatran etexilate, AZD-0837) or factor Xa (e.g., rivaroxaban, apixaban, betrixaban, DU176b, idrabiotaparinux). These drugs have predictable pharmacokinetics that allow fixed dosing without laboratory monitoring, and are being compared with vitamin K antagonists or aspirin in phase III clinical trials [corrected]. A new vitamin K antagonist (ATI-5923) with improved pharmacological properties compared with warfarin is also being evaluated in a phase III trial. None of the new agents have as yet been approved for clinical use.
