Summary: This study is researching an experimental drug called REGN7508 (called study drug). The study is focused on adults undergoing elective, unilateral (one side) total knee replacement surgery. The aim of the study is to see how effective the study drug is at preventing venous thromboembolism (VTE) and other related diseases after total knee replacement surgery. The study is looking at several other r...

Summary: The goal of this clinical trial is to learn if apixaban (a pill) is a safe and easier alternative to taking enoxaparin (a daily shot) to prevent blood clots after head and neck cancer surgery. It will also learn about side effects of both medicines. The main questions it aims to answer are: Can apixaban be used safely instead of enoxaparin to prevent blood clots after surgery? Do patients find api...

Summary: The goal of this observational study is to analyse the association between anti-factor Xa activity (antiXa) and the occurence of venous thromboembolism (VTE; either deep vein thrombosis and/or pulmonary embolism) in critically ill patients who are admitted to an intensive care unit. The main questions it aims to answer are: * What is the association between antiXa and VTE? * What is the associatio...

Summary: We will give an anticoagulant against portal vein thrombosis, and watch for the results.

Summary: The goal of this randomized clinical trial is to evaluate if we can use placental pathology in a prior pregnancy which had an adverse outcome, such as early delivery, stillbirth, a baby born smaller than expected, or severe forms of high blood pressure during pregnancy, to guide treatment in the subsequent pregnancy and reduce risk of recurrent adverse pregnancy events. The main questions it aims ...

Summary: The goal of the CRETE Studies is to investigate the newly identified age-dependent heterogeneity in the efficacy of enoxaparin in reducing the risk of central venous catheter-associated deep venous thrombosis in critically ill children.

Summary: Allograft vascular thrombosis is a devastating complication in kidney transplantation in adults and older children. Though uncommon, it is often irreversible and represents the main cause of graft loss within after kidney transplantation in adults and in the first post-operative year in children. Since allograft thrombosis is usually observed in the first 48h post-operatively, the need to promptly...

Summary: Venous thromboembolism (VTE) is currently the second cause of death in women of reproductive age worldwide. The incidence of VTE during pregnancy is 1.2 to 1.4/1000 women, half of VTE occurring during postpartum and as PE in majority of cases, accounting for 8.8% of maternal deaths. Majority of postpartum VTE occurs in women with one or more moderate risk factors (obesity, caesarean section, postp...

Summary: This is an international, open-label, stratified randomized controlled trial with Bayesian adaptive stopping rules to compare the effects of therapeutic-dose heparin vs. usual care pharmacological thromboprophylaxis on outcomes in patients admitted to hospital with community acquired pneumonia (CAP).

Summary: Currently, Enoxaparin is the usual prophylactic anticoagulant treatment at the acute and sub-acute phases of spinal cord injury (SCI). Patients at the sub-acute phase of SCI (rehabilitation) will be given either Enoxaparin 40 mg/day (control) or Apixaban 2.5-5 mg twice a day. Apixaban dose will be determined by the treating physician. Treatment will be continued for either 6 or 12 weeks following ...

Summary: This study is a multicenter, randomized, open-label, positive-controlled Phase II clinical study to evaluate the efficacy and safety of H001 capsules in the prevention of venous thromboembolism (VTE) in subjects undergoing Total Knee Arthroplasty.

Summary: Endovenous interventions are keyhole operations for varicose veins that are carried out from within the vein itself. Varicose veins are enlarged veins close to the surface of the skin. They are connected to the bigger deeper veins in the leg (known as deep veins). Because of this, operations to close the varicose veins can increase the chance of a blood clot forming in the deep veins. Blood clots ...
