Filter by:This is a Phase 3,multicenter, randomized, open-label, blinded endpoint evaluation study comparing the effect of abelacimab relative to apixaban on venous thromboembolism (VTE) recurrence and bleeding in patients with cancer associated VTE (ASTER)
This is an observational study in which patient data from the past on venous thromboembolism (VTE) in patients with cancer is studied. VTE is a condition in which a patient has problems due to the formation of blood clots in the veins. Blood clots can reduce the flow of blood to vital organs such as the heart and lungs, which can lead to them becoming damaged. VTE can also be "recurrent". This means that the blood clots have returned after treatment. People who have cancer have an increased risk of developing VTE. Three main types of anticoagulation treatments ("blood thinners") have been available for patients with cancer who also have VTE - Low molecular weight heparins (LMWHs) - Vitamin K antagonists (VKAs) - Non-vitamin K antagonist oral anticoagulants (NOACs) The treatment rivaroxaban belongs to the NOACs. Compared to other treatments available to patients who have cancer and VTE, NOACs may cause fewer medical problems and can be easier for patients to take correctly. In this study, the researchers will collect data about: - the type of VTE treatments given and for how long the treatments are taken - the risk of blood clots returning in the veins after treatment, any events of major bleeding, and the number of deaths in patients with cancer who do not have a high risk of bleeding The researchers will compare this information in the patients - who received rivaroxaban to the patients who received LMWHs - who received NOACs to the patients who received LMWHs. There will be no required visits with a study doctor or required tests in this study. The researchers will look at the health information from adult patients in Sweden who were diagnosed with cancer between 2013 and 2019 and also have VTE. The researchers will collect this information from Swedish health registers including the Cancer Registry, National Patient Registry, Prescribed Drug Registry, and Cause of Death Registry.
The study is aimed at assessing the role of the activity of high-risk markers of thrombotic events (MCP-1, MIP1α, IP-10, phosphatedylserine, calreticulin) on the development of thrombotic complications in patients with COVID -19.
Patients with cancer are more likely than those without cancer to develop blood clots (deep vein thrombosis and pulmonary embolism), which are treated using blood thinners (anticoagulants). When clots occur, cancer patients carry a higher risk of recurring clots and more likely to bleed on blood thinning treatments. Therefore, it is critical to use blood thinners that optimize the safety and benefits. There are two main types of blood thinners that are recommended. The tablets which are direct-acting oral anticoagulants and the injections (low molecular-weight heparin). Clinical trials show the tablets may reduce clot risk but may potentially lead to more frequent bleeding, particularly in those with certain risk factors such as stomach ulcers, previous bleeding problems, certain cancer type. We aim to examine the effectiveness and safety of the tablets versus the injections for treatment of clots in cancer patients, to better understand these treatments' benefits and risks.
There is a lack of consensus on whether women with proteinuric kidney disease benefit from prophylactic anticoagulation during pregnancy to reduce the risk of venous thromboembolism. This pilot study will investigate the feasibility of obtaining thrombosis profile data using a viscoelastic haemostasis monitor - Sonoclot - from pregnant women with kidney disease, and exploratory analyses to elucidate correlations between output values and clinical parameters
Aim to determine if aspirin 81 mg orally twice daily is effective and safe as an extended VTE chemoprophylaxis agent after major abdominal surgery for IBD patients. Study will perform an open label trial of aspirin for VTE prophylaxis compared standard of care.
This is a prospective chart study that will aim to assess objective data on compliance levels to low molecular weight heparin (LMWH) injections among pregnant and postnatal women undergoing VTE thromboprophylaxis treatment at Cork University Maternity Hospital. This is a study that will help shine light on accurate data for compliance and possible factors affecting it, which will be useful for more individualised treatment plans for future patients. Patients at higher risk of Venous thromboembolism undergoing VTE thromboprophylaxis will be invited to participate in the study. Once the patient reads the information leaflet and signs consent, data will then be collected from the patients medical record. The patient will be given a smart sharps bin with an individual, unique product code. This device will be provided by HealthBeacon, a Dublin based start-up company. The device will be personalised with the treatment schedule pre-loaded onto it. When a used LMWH injection is disposed into the smart sharps bin, an infrared sensor is activated. The system captures an image of the injection in the chamber before moving it to the normal 'sharps' container of the bin for disposal. The captured image is time-stamped and sent to HealthBeacon's electronic database. HealthBeacon will only have the data pertaining to the disposal of injections for each sharps bin (i.e. the timing of the disposal of each used injection in each pre-coded bin). We are blinded to the compliance information and will only will receive the raw Data once treatment is completed. Data will be analysed to determine compliance of LMWH injections. This study will enable us to have a better insight on accurate compliance rates for LMWH injections in pregnant women at higher risk for venous thromboembolism (VTE). Understanding compliance with LMWH injections and the factors which can affect it, will hopefully guide future information and education that we offer to patients who are prescribed LMWH injections and help decrease maternal mortality rates in future.
This is single centre pilot, randomized controlled trial assessing postpartum prophylactic anticoagulation with 3 weeks of LMWH followed by 3 weeks of Aspirin compared to standard of care of prophylactic LMWH for 6 weeks at moderate to high risk of developing VTE.
Venous thromboembolism (VTE) is a complex multifactorial disease, mainly manifested by deep vein thrombosis (DVT) and pulmonary embolism (PE). VTE events increase the length of hospitalization and treatment costs and seriously affect the quality of life of patients, so it is increasingly appreciated to identify high-risk patients with VTE and take preventive measures. The Padua prediction score (PPS) and Caprini risk assessment model (RAM) are widely used in clinical practice as common risk assessment scales in medical and surgical departments, respectively. And D-dimer levels have been considered as a well indicator to rule out acute VTE. Previous epidemiological studies on VTE have found the risk of VTE is significantly higher in hospitalized patients than in the general population and the prophylaxis decisions vary among countries, hospitals and departments, indicating current in-hospital VTE prevention strategies are far from optimal and it's imperative to regionalized control of VTE. Therefore, a single-institution-based risk profile study of in-hospital VTE patients is designed to explore current situation of VTE occurrence and predictive efficacy of widely used risk assessment models as well as D-dimer in one of the general hospitals in Beijing, China.
Research Question: In adult SCD patients with CVC, is it feasible and safe to conduct an adequately powered RCT to evaluate the use of rivaroxaban as thromboprophylaxis in this population? Study Design: The study is a vanguard pilot double blind multi-centre randomized controlled trial. Participants with SCD and CVC will be randomized to either rivaroxaban 10mg PO daily or placebo for the duration of CVC in situ or for up to one year, whichever is less. After screening (day -7 to day -1), patients will be followed at day 1, months 3 (+/- 15 days), 6 (+/- 15 days), 9 (+/- 15 days), and 12 (+/- 15 days). Study Objectives: The primary objective is to estimate the proportion of eligible patients who will enroll into a trial of thromboprophylaxis. Secondary objectives include (a) document indications for central venous catheter (CVC), (b) summarize duration of CVC insertion prior to enrollment, (c) estimate adherence to the study drug, (d) estimate proportions of participants being compliant with study procedures, and lost to follow up. Exploratory objectives will assess thrombotic, bleeding, and quality of life outcomes.
