Filter by:The objective of this study is to compare the efficacy, safety of DU-176b 30mg or DU-176b 15mg versus enoxaparin sodium for the prevention of venous thromboembolism in patients after elective total hip arthroplasty.
The objective of this study is to assess the efficacy, safety and dose-response relationship of DU-176b compared with placebo for the prevention of venous thromboembolism in patients after elective total knee arthroplasty.
CV185-079 is a multiple dose Apixaban Pharmacokinetics/Pharmacodynamics (PK/PD) study in pediatric subjects. The objective of this study is primarily to study the PK/PD of Apixaban in pediatric subjects with a central venous catheter.
To supplement the current evidence of the effect of Pradaxa® (dabigatran etexilate) on coagulation parameters, including a calibrated thrombin time test, in patients with moderate renal impairment undergoing elective total hip- or knee-replacement surgery, this PK/PD study will be conducted.
The objective of this study is to assess the efficacy and safety of DU-176b compared with enoxaparin sodium for the prevention of venous thromboembolism in patients after elective total hip arthroplasty.
The objective of this study is to evaluate the safety and efficacy of DU-176b compared with enoxaparin sodium for the prevention of venous thromboembolism in patients after elective hip fracture surgery.
The objective of this study is to assess the efficacy and safety of DU-176b compared with enoxaparin sodium for the prevention of venous thromboembolism in patients after elective total knee arthroplasty.
The purpose of this study is to describe the incidence of thromboembolic events in relation to pregnancy and when in pregnancy and the puerperal period.
Background Patients with cancer and a first deep venous thrombosis of the leg or pulmonary embolism (venous thromboembolism, VTE) are generally treated with low molecular weight heparin (LMWH)injections for 6 months, since this treatment is associated with a reduced incidence of recurrent VTE compared to vitamin K antagonists (VKA). It is recommended that patients with active malignancy (metastatic cancer and/or ongoing cancer treatment)continue anticoagulant treatment. However, it is unknown whether LMWH is still superior compared to VKA for the long-term anticoagulant treatment. Aim The aim of this study is to evaluate whether low-molecular-weight heparin more effectively reduces recurrent VTE compared to vitamin K antagonists in patients with cancer who have already completed 6 to 12 months of anticoagulant treatment because of deep venous thrombosis of the leg or pulmonary embolism. Hypothesis The investigators hypothesize that LMWH is more effective compared to VKA in the long-term treatment of VTE in cancer patients who have already been treated for 6-12 months with anticoagulants. Design This is a multicenter, multinational, randomized, open label trial. Patients Patients with a malignancy (all types, solid and hematological) who have received 6-12 months of anticoagulation for VTE and have an indication for continuing anticoagulation, will be randomly assigned to six additional months of LMWH or VKA. LMWH will be administered in a weight-adjusted scheme, with 65-75% of therapeutic doses. All types of LMWH and VKA are allowed, as long as weight adjusted dosing is possible for LMWH. The target INR will be 2.0-3.0. The primary efficacy outcome is symptomatic recurrent VTE, i.e. deep vein thrombosis and pulmonary embolism. The primary safety outcome is major bleeding. Sample size A total of 65 to 87 recurrent VTE events are needed to show a 50% reduction with LMWH as compared to VKA (type I error 0.05, two-sided, power respectively 80 and 90%). To observe 75 events, with a 10% event rate per half year in the VKA arm and 5% in the LMWH arm a total of 1000 patients will need to be included. Organisation Outcomes will be adjudicated by a central adjudication committee. A steering committee will be formed, preferably consisting of one member of every participating center. An electronic case report form will be used for data collection. Also, an electronic trial master file will be used.
A prospective data registry for all patients who undergo IVC (Inferior Vena Cava) filter placement or retrieval at Stanford. Potential enrollees will already be undergoing the procedure. If patients are willing, they will be prospectively enrolled prior to the procedure. As part of the study, chart and clinical data reviews will be used to track patient progress and response to the treatment.
