Active clinical trials for "Thrombosis"

This is a Phase III, randomized, placebo controlled, blinded, parallel two arm, multicentre trial that will compare rivaroxaban 10mg daily with placebo in patients with symptomatic leg Superficial Vein Thrombosis (> or = 5cm) that otherwise would not initially be treated with anticoagulant therapy.

To evaluate the efficacy of ultrasound accelerated thrombolysis using the EkoSonic® Endovascular System with standard infusion of thrombolytic drug for post-thrombotic syndrome from chronic venous occlusion.

The objective is to determine the optimum dose of thrombolytic and duration of the ultrasound procedure (together defined as the APT Procedure) as a treatment for acute submassive pulmonary embolism (PE). Symptomatic submassive PE are participants with acute (less than or equal to [≤]14 days) PE with normal systemic arterial blood pressure (greater than [>] 90 mmHg) and evidence of RV dysfunction (right ventricular to left ventricular diameter ratio, that is; RV/LV ratio greater than or equal to [≥] 0.9). Participants with submassive PE will be randomized to one of four APT treatment groups: ultrasound of 2 and 6 hours (hrs) with r-tPA 2 milligrams (mg)/hr/catheter and ultrasound 4 and 6 hours with r-tPA, 1 mg/hr/catheter. On 08 June 2016, randomization into treatment group 4 (APT/6 hours-r-tPA/2 mg/hr/catheter) was closed following a reported intracranial hemorrhage (ICH) and death in a study participant in this arm.

Open randomized therapeutic study to assess the efficacy of Xarelto 15mg/day in the recurrence of thromboembolic event compared to an untreated group in patients with chronic portal vein thrombosis without high risk thrombophilia.

Leg compression is considered the basic treatment for superficial vein thrombosis (SVT). However, its use is more or less based on subjective experience while scientific evidence for its efficacy is lacking. There is one uncontrolled trial reporting improvement of clinical symptoms when patients with SVT were treated with fixed compression bandages. This study evaluates the efficacy of compression stockings (23-32 mmHg) in the treatment SVT of the legs. The investigators hypothesis is that compression treatment is superior to no compression in alleviating disease related clinical symptoms.

Rivaroxaban has been developed in the various clinical settings, prevention of venous thromboembolism (VTE)after major orthopedic surgery, prevention of stroke in atrial fibrillation, and in the treatment of acute coronary syndromes. And, in the EINSTEIN-pulmonary embolism (PE) and EINSTEIN-deep venous thrombosis (DVT) programs, rivaroxaban showed non-inferior to standard therapy for the treatment of PE and DVT. However, there has been limited experience of rivaroxaban with secondary VTE prophylaxis in cancer patients. Although cancer-associated DVT or PE was included in previously mentioned EINSTEIN programs, only approximately 5% of the total populations were cancer patients in these studies. Thus, investigators could not automatically translate the results of these studies into the real practice management of cancer-associated VTE patients. Moreover, until now, new oral anticoagulants, including dabigatran and rivaroxaban, have been compared to long-term warfarin therapy, which were well-known inferior agent, but not low molecular weight heparin. In this sense, investigators feel that new oral anticoagulants, particularly rivaroxaban, should be re-investigated in this highly specific patients group. Therefore, investigators are planning to conduct a prospective study evaluating the efficacy and safety of rivaroxaban in Korean patients with cancer-associated VTE.

The purpose of this study is to evaluate the superiority of left atrial appendage occlusion in comparison to oral anticoagulation with a vitamin K antagonist (INR 2-3) related to the frequency of occurrence of at least one bleeding classified as moderate or major within 24 months.

Patients admitted to the intensive care unit are at high risk of developing clots in the veins of the lower extremities. The objective of this study is to examine whether the use of a device that provides intermittent compression to the legs in addition to the use of low-dose blood thinners, provides an additional protection when compared to the use of blood thinners alone. Patients who are admitted to the intensive care unit are receiving low-dose blood thinners to prevent clots are candidates for this study. Patients who are enrolled will continue to receive blood thinners but some will additionally receive the leg compression. The additional use of leg compression may provide protection from clots. The main side effect is possible skin abrasions but this is usually mild. The study is sponsored by King Abdullah International Medical Research Center(KAIMRC) and King Abdulaziz City for Science and Technology(KACST) and will be conducted in several hospitals in Saudi Arabia, Canada, Australia, Brazil and possibly other countries. The study started July 2014 and is to continue for 4 years.

Primary Objective: - To assess the pharmacokinetic (PK) and pharmacodynamic (PD) parameters of Semuloparin [AVE5026] (assessed from the anti-Xa activity of Semuloparin) in children in order to determine the dose to be assessed in a clinical efficacy/safety study in this population. Secondary Objective: - To assess the tolerability of Semuloparin when administered at a weight-adjusted, once daily dose for up to 30 days in patients less than 18 years of age with central venous line.

Recently, several studies reported promising outcomes of patients after external beam radiotherapy (EBRT) for hepatocellular carcinoma (HCC) with portal vein tumor thrombosis. However, conventional EBRT is composed of many fractions (20-35 fractions). On the other hand, stereotactic ablative radiotherapy is a newly emerging treatment method to deliver a high dose of radiation to the target using a few fractions with a high precision within body. SABR increases radiation biologic effect for tumor, makes patients more comfortable due to reduction of the number of hospital visit, and enables patients to receive another treatment more quickly. This study will evaluate SABR effect with 40 Gy in 4 fractions for HCC with major portal vein tumor thrombosis.
