Active clinical trials for "Thromboembolism"

This is a multi-center, prospective, international, randomized (1:1), open-label study with two parallel groups. This phase III study is planned to investigate the efficacy and safety of dabigatran etexilate versus dose-adjusted warfarin on a net clinical benefit endpoint of major bleeding (ISTH criteria) and new venous thrombotic event (VTE) (primary endpoint) with blinded endpoint adjudication.

This is an event driven Phase 3, prospective, randomized, open-label, blinded endpoint evaluation (PROBE) parallel group study in subjects with confirmed VTE. This study is designed to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of edoxaban and to compare the efficacy and safety of edoxaban against standard of care in pediatric subjects with confirmed VTE.

The overarching objective of the study is to determine the effectiveness of LMWH/ warfarin vs. DOAC anticoagulation for preventing recurrent VTE in cancer patients. The intervention strategy is Direct Oral AntiCoagulants (DOAC) therapy with edoxaban, apixaban, rivaroxaban, or dabigatran. The comparator is low molecular weight heparin (LMWH) alone or with warfarin. The information gained will empower cancer patients and physicians to make more informed choices about anticoagulation strategies to manage VTE.

To evaluate the safety and clinical efficacy of left atrial appendage in the prevention of thrombus in patients with valvular heart disease, to improve the product according to clinical conditions, to achieve clinically accurate treatment, and to establish the heart valve, the usefulness and universality of Warfarin's anticoagulant model were verified by the specimen library

The main research question of this study is to obtain further safety and effectiveness data on Pradaxa Pellets in children aged 3 months to less than 12 years in routine clinical practice setting.

Oral anticoagulation treatment (OAC) following clinically successful catheter abla-tion of atrial fibrillation (AF) is controversial. Recent guidelines recommended con-tinuation of OAC in all patients with CHA2DS2VASc score ≥2 even if there is no evidence of recurrent AF (Camm JA et al., Eur Heart J 2012). The net clinical ben-efit of OAC after successful ablation in these patients remains to some extent un-clear. As OAC bears the risk of bleeding events, the ODIn-AF study aims to evalu-ate the positive effect of OAC on the incidence of silent cerebral embolic events in patients with a high risk for embolic events, free from AF after successful pulmo-nary vein ablation. ODIn-AF aims to determine that continued administration of dabigatran is superior in the preven-tion of silent cerebral embolism to discontinuation of OAC after 3 months in pa-tients free from symptomatic AF-episodes with a CHA2DS2VASc score ≥2 after the first pulmonary vein ablation for paroxysmal AF.

Warfarin is an anticoagulant medication that is highly effective at preventing clotting disorders but which has a narrow therapeutic window. If warfarin is under effective patients are at risk of stroke, if it is over effective patients are at risk of bleeding complications. Physicians routinely and regularly measure a blood test (called the "INR") that determines the effectiveness of warfarin and have a range of test values (the "therapeutic range") in which they try to keep the patient. By convention warfarin is taken at dinnertime, however this is the same time of day that highly variable consumption of dietary vitamin K occurs (found largely in green leafy vegetables) and vitamin K alters the effectiveness of warfarin. Given vitamin K has a very short half-life (i.e. it is only active for a short period of time after it is ingested) it may make more sense to take warfarin in the morning (when very little vitamin K is ingested) to produce a more consistent drug effect. The purpose of this study is to determine whether switching current warfarin users from evening to morning dosing decreases time spent outside the therapeutic INR range.

Patients with cerebral hemorrhage (ICH) have a high risk of venous thromboembolism. Intermittent pneumatic compression combined with elastic stockings have been shown to be superior to elastic stockings alone in reducing the rate of asymptomatic deep vein thrombosis after ICH in a randomized trial (4.7% vs. 15.9%). Graduated compression stockings alone are ineffective in preventing deep vein thrombosis in patients with ischemic or hemorrhagic stroke. Less clear is the role of anticoagulation in the prevention of venous thromboembolism in patients with ICH because the use of anticoagulants may cause an enlargement of the hematoma. In a multicenter, randomized trial, the investigators will assess the efficacy and safety of enoxaparin in the prevention of venous thromboembolism in patients with spontaneous intracerebral hemorrhage. Enoxaparin (40 mg once daily) or standard therapy (graduated compression stockings and/or intermittent pneumatic compression and/or early mobilization) will be given subcutaneously for not less than 10 days beginning after 72 hours from stroke onset.

To determine the therapeutic window of BIBR 1048 in order to select doses for further studies in the development plan. Twice daily regimen will be tested for most dose levels and once daily administration will also be evaluated when appropriate.

The main objectives of this large phase IIb/III paediatric study are to assess the efficacy and safety of dabigatran etexilate relative to standard of care and to document the appropriateness of the proposed dabigatran etexilate dosing algorithm for use in patients from birth to less than 18 years of age.
