Filter by:The study aims to document the flow of German patients with cancer and acute deep vein thrombosis from first visit to diagnosis and treatment, the applied diagnostic procedures, and therapy modalities.
This is an observational study to analyze the influence of surgery duration and tourniquet time in the incidence of deep venous thrombosis (DVT) in patients that had undergone total knee arthroplasty (TKA).
Therasphere will be administered via catheter through the Hepatic Artery to treat patients with Hepatocellular Carcinoma and Portal vein Thrombosis.
Currently, guidelines and clinical practice differ considerably with respect to use of anticoagulant treatment during cast immobilization of the lower leg. Trials that have been carried out were aimed at efficacy only, had small sample sizes and therefore mainly used asymptomatic thrombosis as endpoint. From these trials an overall risk benefit-balance could not be established, hence the current controversy. In the proposed study the investigators will use relevant symptomatic endpoints in a large cohort of patients. Furthermore the investigators will follow subjects with an adverse event for a longer period, during which the investigators will assess the long term sequelae of these events. Lastly, the investigators will determine high risk groups that will benefit most from anticoagulant treatment. Objective: Comparative effectiveness research to determine cost-effectiveness of two existing policies, i.e. treatment with low molecular weight heparin (LMWH) during lower leg plaster cast immobilization following surgical or conservative treatment. In addition the investigators will investigate personalized prophylaxis based on genetic and acquired risk factors.

Patients with cancer have a high risk of developing venous blood clots or thromboembolism (VTE). In an effort to target patients at highest risk of VTE for thromboprophylaxis (protective treatment for blood clots), numerous studies have identified serum biomarkers for risk of future VTE. There is also increasing evidence pointing to a prophylactic effect of statin therapy on the risk of developing VTE in high-risk populations including patients with advanced cancer. The purpose of this research study is to find out whether treatment with rosuvastatin (the study drug) reduces the risk of VTE in patients with cancer receiving chemotherapy. This study is specifically investigating the impact of rosuvastatin therapy on serum biomarkers (D-dimer and others) that indicate a risk for VTE, as well as safety and tolerance of rosuvastatin therapy in this population. This is a phase II randomized crossover study with two 3-4 week treatment periods during which all enrolled patients will receive 20 mg of rosuvastatin once a day by mouth or a matching placebo tablet. Approximately two tablespoons of blood will be collected for biomarker analysis at the beginning and end of each treatment period. After the first treatment period there will be a 3-5 week break where subjects will undergo a washout. Following this washout period every subject will "crossover" or begin taking the alternative therapy so everyone enrolled will receive the study drug either during the first or the second treatment period. Biomarker levels will be analyzed in both treatment periods and compared to baseline, with every patient acting as their own control.
The objective of this study is to evaluate the efficacy, safety, pharmacokinetics (PK) and pharmacodynamics (PD) of two different dosages of rivaroxaban in the treatment of deep vein thrombosis (DVT) and the prevention of the occurrence and the recurrence of DVT or pulmonary embolism (PE) in Japanese patients with acute symptomatic DVT without symptomatic PE.
The study objective is to investigate the pharmacodynamics (effects of a drug product) when switching the treatment from warfarin to rivaroxaban. 84 young, healthy subjects will participate; they will be treated following a randomized, parallel-group (Treatments A, B, and C), placebo-controlled (Treatment B), and single-blind (Treatments A and B) design. The first two groups (A, B) will receive warfarin for approximately one week to adjust their blood coagulation values to a specific level, i.e. to maintain an INR (international normalized ratio) of 2.0 - 3.0. This range is commonly used for long-term anticoagulant treatment. The first group (A) will receive rivaroxaban for four days, the second group (B) will take placebo. On the last day, all subjects in groups A and B will receive vitamin K to neutralize the effects of warfarin. The third group (C) will not undergo prior treatment with warfarin but will receive rivaroxaban for four days.
To date, the investigators still do not know the annual incidence of Superficial Vein Thrombosis in the legs, although the investigators do know that this pathology is frequent and the investigators can assume its incidence is greater than Deep Vein Thrombosis which is of 1 to 2 cases per year per 1,000 inhabitants. Furthermore, the high percentage of SVT with concomitant DVT and Pulmonary Embolism only concerns patients seen in vascular medicine, so it is important to re-evaluate this rate on an unselected population from general practice.
The purpose of this study is to evaluate the efficacy and safety of rivaroxaban versus fondaparinux in the treatment of superficial vein thrombosis (SVT).
