Active clinical trials for "Venous Thromboembolism"

Trauma patients are at high risk of developing deep vein thrombosis (DVT) and pulmonary embolism (PE). The incidence of DVT varies greatly from 5-63% among studies depending on patient's individual risk factors, modality of prophylaxis, and methods of detection. The incidence of PE may be as low (0.3-4.3%) but carries a mortality of 20-50% which makes prevention of DVT of the utmost importance. The current standard of care for DVT prophylaxis in the trauma patient with high risk of DVT is enoxaparin, a low molecular weight heparin, administered twice a day as long as anticoagulation in not contraindicated. Many studies have demonstrated its efficacy when compared to mechanical compression and to unfractionated heparin, however one of the most robust of these studies still reported an DVT incidence of 35% in patients treated with enoxaparin. Another drug, fondaparinux, is a selective factor Xa inhibitor that could offer added benefits over enoxaparin such as once daily dosing and a drastically reduced risk of heparin induced thrombocytopenia (HIT). Fondaparinux has been already be widely used in post-operative hip surgery and major knee surgery patients with good results. It has also been shown to be effective in DVT prophylaxis in patients who have had major abdominal surgery and also in acute medical patients. Fondaparinux has yet to be used in trauma patients. Trauma patients are a diverse and distinct population given the acuity of their injuries and their increased risk of bleeding who at this time still do not have a perfect method for DVT prophylaxis. We hypothesize that fondaparinux will be effective in decreasing the risk of DVT when used in the trauma patient population. This is a non randomized prospective cohort study designed to test the efficacy of fondaparinux in the prophylaxis of DVT and PE in trauma patients.

The primary efficacy objective is to evaluate whether dabigatran etexilate is superior to placebo in the long-term prevention of recurrent symptomatic venous thrombo-embolism (VTE) in patients with symptomatic deep-vein thrombosis (DVT) or pulmonary embolism (PE) who completed 6 to 18 months of treatment with vitamin K antagonist (VKA).

To determine the safety of prophylaxis with Tinzaparin low molecular weight heparin in primary brain tumor patients. 2. To determine the incidence of deep venous thrombosis or pulmonary embolism in brain tumor patients who will be receiving Tinzaparin as primary prophylaxis. 3. To determine the overall survival of patients with malignant glioma who receive Tinzaparin. 4. To determine the bone density before and after prophylactic Tinzaparin.

The primary objective of this study is to evaluate the effects of enoxaparin on venous thromboembolism incidence and bleeding rate (major and minor bleeding) in patients undergoing curative abdominal cancer surgery. The secondary objective is evaluate the incidence of adverse events of enoxaparin in these patients.

The study drug, BAY59-7939, is a new drug currently being tested in the prevention of VTE. It directly inhibits factor Xa, a blood component in the pathway which leads to coagulation (clotting of blood cells). It is available as a tablet. The purpose of this study is to compare the safety and efficacy of BAY59-7939 with the safety and efficacy of the licensed drug Enoxaparin. Enoxaparin, a so-called low molecular heparin, is approved and widely used in the area of thromboprophylaxis and will be given once daily subcutaneously. In this study 4 different doses of the investigational drug BAY59-7939 will be tested in comparison to Enoxaparin. You will receive during the study either one of the following BAY59-7939 treatments or Enoxaparin. The following doses of BAY59-7939 will be tested: Dose I ; Dose II, Dose III, Dose IV. This study will run for approximately 7 months in a number of countries. In total, up to 600 patients may participate in this study.

The study objective is to evaluate the efficacy and safety of oral YM150 for prevention of venous thromboembolism in subjects undergoing hip fracture surgery or surgery in the lower extremities.

The aim of the study is to evaluate the efficacy and safety of Bemiparin, a second-generation LMWH, in the prophylaxis of VTE (using a postoperative regimen, i.e. administering the first dose 6 hours after finishing the surgical procedure) for 28 days compared to 8 days, in oncological surgery.

The objective of this study is to determine the comparative efficacy and safety of two oral regimens of dabigatran etexilate, compared to a standard subcutaneous regimen of enoxaparin, in prevention of venous thromboembolism in patients with primary elective total hip replacement surgery.

The purpose of this study is to determine whether TTP889 prevents venous thromboembolism following surgery to repair hip fracture.

In patients with malignant glioma, to determine the efficacy of prophylaxis with LMWH (dalteparin) compared to placebo, both commenced beyond the immediate postoperative period, for the prevention of VTE.
