Active clinical trials for "Venous Thrombosis"

Prospective cohort study aimed at optimizing the duration of anticoagulant treatment in patients at their first episode of proximal deep venous thrombosis (DVT) of the lower extremities, whose pathogenesis is either unknown (idiopathic DVT) or associated with minimal risk factors for thrombosis, with the help of an algorithm which incorporates both ultrasonography and D-dimer information. All patients will be followed-up until 1) the achievement of a major end-point; 2) the date of lost to to followup; 3) the date of death; 4) the date of study stop. The purpose of this study is to demonstrate the safety of withholding anticoagulation from a subgroup of patients with proximal DVT whose veins have recanalized and present with a repeatedly negative D-dimer (at baseline, after 1 and 3 months). The approach will be deemed to be safe if the annual rate of recurrent VTE in patients who will have their anticoagulation discontinued is lower than 5%.

The three purposes of this study are the following: To compare during a 6-month treatment the safety and effectiveness of idrabiotaparinux (SSR126517) with that of idraparinux (SR34006), taking into account new events of deep venous thrombosis (DVT) and pulmonary embolism (PE), and bleeding risk; To compare the activities of idrabiotaparinux and idraparinux directly in blood during and after a 6-month treatment; To check the ability of avidin (SSR29261) to reverse the blood thinning activity of idrabiotaparinux at the end of a 6-month treatment period.

Study objectives : To evaluate the efficacy/safety profile of enoxaparin once a day treatment in acute venous thromboembolic disease.

The optimal treatment of superficial venous thrombosis (SVT) is still uncertain. Though low molecular weight heparin (LMWH) is considered the treatment of choice, studies conducted so far do not give clear indications of the optimal dose and duration of treatment. This study aims to evaluate whether an intermediate therapeutic dose of LMWH (parnaparin) is more effective than a prophylactic dose and also to assess whether 10 rather than 30 days are sufficient for treatment.

This study is designed to investigate the incidence of deep vein thrombosis in patients receiving a perisurgical regimen of epoetin alfa (PROCRIT®) as compared to patients receiving standard of care blood conservation management.

The purpose of this study is to assess the effect of the anticoagulant(blood thinner) Clexane on the development of leg clots following electrophysiology studies (EPS) and or radiofrequency ablation (RFA). People who suffer heart palpitations will sometimes need hospital admission to undergo an electrophysiology study ( and or a Radiofrequency Ablation)in order to diagnose and or treat their condition. Radiofrequency ablation is a procedure to stop abnormal heart rhythms. EPS/RFA studies require the puncture of the leg veins . Previous experience has shown that following the puncture of leg veins there is a small risk of developing a blood clot in the leg. It is not known whether giving blood thinners (anticoagulants) after the procedure will decrease this risk Enoxaparin Sodium (Clexane) is an anticoagulant used extensively and safely following bone (Orthopaedic) surgery to prevent blood clots from developing in the legs

FIDO was a multicentred randomized, open-label trial that compared fixed-dose UFH with fixed-dose LMWH for initial treatment of VTE. Patients were followed for 3 months during which they received warfarin (target INR 2.0-3.0).

This study is a single-arm, phase IV trial, of apixaban as treatment of venous thrombosis in patients with cancer. The current standard treatment of venous thrombosis in cancer patients is subcutaneous injections with low molecular weight heparin. During the last 5 years several new direct acting oral anticoagulants have been tested out as treatment of venous thrombosis. But very few cancer patients were included in the phase III clinical trials of the direct acting oral anticoagulants. Thus, there is a lack of information on how cancer patients with venous thrombosis will respond to treatment with direct acting oral anticoagulants. The current study will investigate the direct acting oral anticoagulant apixaban in cancer patients with venous thrombosis.

This retrospective cohort study aims to characterise outcomes for patients treated on an intensive care unit (ICU) with COVID-19 in England and Wales, one year after discharge from hospital. Outcomes will be compared with patients admitted as an emergency to an ICU for other conditions. The study will use existing national audit data linked to routine healthcare datasets.

Assess the relative change in thrombus volume as determined by two assessments (Baseline and Day 14-21) with magnetic resonance venography (MRV) in subjects with deep-vein thrombosis (DVT) treated with either an edoxaban monotherapy regimen or a low molecular weight (LMW) heparin/warfarin regimen.
