Active clinical trials for "Venous Thromboembolism"

Primary objective: To determine whether aspirin (ASA) can lower the incidence of Venous Thromboembolism(VTE) in patients with Glioblastoma (GBM). Secondary objectives: To determine clinical and laboratory factors which are associated with increased risk of VTE If it is determined that ASA reduces the incidence of VTE in patients with GBM, then to determine the clinical and laboratory factors which are associated with an increased benefit from the drug.

Due to increasing of life expectancy, patients with von Willebrand disease are exposed to age-related pathologies such as cancer or cardiovascular diseases. Management of thrombotic events is challenging given the inherent bleeding risk in von Willebrand disease. Few data are currently available in the literature. The aim of the study is to describe the frequency and nature of arterial and venous thromboembolic events and atrial fibrillation in patients with von Willebrand disease in the West of France. The investigators will perform a retrospective multicenter study conducted in the von Willebrand population of the French West. Von Willebrand adult patients followed in one of the French West medical centers participating in the study, who presented deep vein thrombosis, pulmonary embolism, ischemic stroke, transient ischemic attack, acute coronary syndrome, acute limb ischemia, atrial fibrillation, arteriopathy of the lower limbs, angina will be eligible.

In individuals with obesity, the optimal dosing and duration of venous thromboembolism (VTE) prophylaxis in settings representing acute medical illness or surgery is limited due to lack of randomized controlled trials (RCTs) focusing specifically on this population. Evidence suggests that in obese participants, both higher dosing and duration of VTE prophylaxis with Low Molecular Weight Heparins (LMWH) may be required to achieve a therapeutic effect similar to non-obese participants. This non-interventional study utilizes data already collected from a usual clinical practice setting in the Optum US clinical database, representing obese participants hospitalized with an acute medical condition or undergoing surgery receiving enoxaparin prophylaxis. Its aim is to compare the impact of the following enoxaparin prophylaxis strategies on the incidence of symptomatic VTE and major bleeding in the overall study population and prespecified subgroups: High versus conventional dose Extended versus conventional duration Combined High-Dose and Extended-Duration versus Conventional-Dose and Conventional-Duration. The first date of enoxaparin prophylaxis will be the index date.

The LIFE study (Lung cancer, Immunotherapy, Frailty, Effect) is investigating the unselected 'real life' non-small cell lung cancer (NSCLC) population treated with immune checkpoint inhibition.

Interventional, no-randomized, open-label, and single arm multicentre study of apixaban for the prevention of thromboembolic events during induction therapy in transplant-eligible patients with newly diagnosed multiple myeloma who receive bortezomib, thalidomide, and dexamethasone (VTD) during the induction phase of therapy prior to autologous stem cell transplantation (ASCT). The current study is designed to evaluate the efficacy and safety of apixaban during the induction period. Efficacy will be defined as a composite endpoint of acute symptomatic proximal and distal deep venous thrombosis, pulmonary embolism, VTE related deaths, and acute ischemic stroke.

The purpose of this study is to show feasibility (efficacy and safety) of Rivaroxaban in the treatment of VTE in cancer patients in comparison to the standard treatment with low molecular weight heparin (LMWH). Tumor patients with active cancer and newly diagnosed thromboembolic events are randomised to receive either Rivaroxaban or the standard treatment with low-molecular heparin.

Introduction: Venous thrombosis (VTE), including both deep vein thrombosis (DVT) and pulmonary embolism (PE) remains a frequent complication in patients admitted to the Intensive Care Unit (ICU). Multiple prediction models for estimating the risk of VTE have been developed. However, many models have not been externally validated. The aim of this study is to perform a comprehensive external validation of pre-existing prediction models for predicting the risk of in-hospital VTE in critically ill patients. In case current risk assessment models fail, the investigators aim to additionally develop and internally validate a new risk prediction model. Methods: During the first phase of the study the investigators will perform external validation of existing prediction models. The performance, discrimination, calibration and clinical usefulness of the models will be evaluated. In the second phase of the study, in case performance of current risk assessment models is deemed insufficient for clinical application, the investigators will develop a model for predicting the risk of in-hospital VTE in critically ill patients. A multivariable prediction model will be constructed using a combination of predefined candidate predictors. This model will be internally validated and performance will be compared with performance of existing VTE risk prediction models. Dissemination: This protocol will be published online. This study will be reported according to the Transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) statement and this study will be submitted to a peer-reviewed journal for publication.

Venous thromboembolism (VTE) is the second leading cause of death in patients with cancer, after disease progression. VTE is increasingly recognized as a complication in patients with hematologic malignancies and various studies have reported high rates of VTE. Critically ill patients are at high risk of VTE and should all receive thromboprophylaxis. Given the increasing number of patients with HM (hematologic malignancies) / HCT (Hematopoietic cell transplantation) who develop critical illness, and their often prolonged course, it is imperative to understand the incidence and risk factors for VTE, and to evaluate the efficacy and risks associated with both chemical and mechanical thromboprophylaxis Therefore, the investigators plan to evaluate retrospectively the VTE / PE (pulmonary embolism) incidence in HM /HCT patients at the University of Toronto, and the complications associated with it (including death). In addition, the investigators want to evaluate the use, type (mechanical or pharmacological) and timing of thromboprophylaxis. And lastly, the investigators will determine the incidence of bleeding and of complications associated with chemical and mechanical thromboprophylaxis. The investigators will describe the change in VTE incidence over the last 10 years. The investigators know that patients with COVID-19 infection are at higher risk of thrombosis than non-COVID patients. As such, HM/HCT COVID-19 pts will comprise a subgroup, which will be compared with patients who are not not positive for COVID-19. If these numbers are low, COVID-19 status will be included as a predictive variable in our modelling. The results of this research program will help define indications and safety of VTE prophylaxis; and will inform the development of clinical practice guidelines.

This is a phase II, pragmatic, prospective, randomized, double-blind, adaptive clinical trial examining the efficacy of statins and aspirin in the reduction of acute lung injury and venous thromboembolism in patients with fibrinolysis shutdown.

This trial is a prospective, single-center Phase II randomized study to demonstrate the superior efficacy of Fondaparinux Sodium subcutaneous injections in patients undergoing CABG surgery (isolated and redo isolated) versus treatment with placebo. All consecutive patients scheduled for CABG surgery that meet the general inclusion and none of the exclusion criteria will be considered for enrollment in the study. Consecutive patients will be randomized on the day of admission prior to their CABG surgery into one of two groups. One group will be randomized to the placebo while the second group will receive 2.5 mg Fondaparinux Sodium injections. Both groups will receive routine mechanical prophylaxis as determined by the treating physicians. Group randomized to receive Fondaparinux Sodium will receive a 2.5 mg SQ daily drug dose starting 12 +/- 2 hours post-wound closure or the following day in the morning (at the discretion of the cardiothoracic surgeon). The second dose would be administered 24 hours later and the dosing will then be once a day. The group randomized to placebo will receive subcutaneous equivolume isotonic saline at the same time points described above. Patients randomized will receive a 2.5 mg dose of Fondaparinux Sodium or placebo subcutaneously for a total of 3-9 days post CABG with day 1 being the day of surgery. The drug will be discontinued if the patient is discharged before day 9. If the patient stays for more than 9 days inside hospital, a duplex would be obtained per protocol and further DVT prevention measures would be instituted per the discretion of treating physician. Patients will be assessed daily while hospitalized for any symptoms and adverse reactions and will undergo laboratory testing (CBC, PT/INR, PTT and UA) as specified in the protocol. Post-op day 3-9(no later than 2 days after the last preventive drug dose) patients will undergo the protocol specific lower limb venous duplex scan and earlier if symptomatic. Patients will also be contacted (phone/office visit) for follow-up 25-35 days post CABG to assess for signs or symptoms of deep venous thrombosis or thromboembolism and for any potential complications.
