Filter by:Thromboprophylaxis options are limited for patients with acute spinal cord injury (SCI) and there are no studies on direct oral anticoagulants (DOACs) for thromboprophylaxis in this population. Participants will be randomized to apixaban 2.5 mg twice daily or standard dose low-molecular-weight heparin (LMWH), either enoxaparin 40 mg or dalteparin 5000 units, subcutaneously once daily for 90 days or until fully mobilized, whatever comes first. Thromboprophylaxis will be started as soon as hemostasis is achieved. The primary outcome for this pilot study will be the recruitment rate per year (i.e. the screened to enrolled ratio). The primary efficacy endpoint will be a composite of symptomatic, objectively verified, venous thromboembolism (VTE), defined as upper or lower limb deep vein thrombosis (DVT) and/or pulmonary embolism (PE) or sudden death where PE cannot be excluded. The primary safety endpoint will be major bleeding.
Comparison of Oral anticoagulants (warfarin, apixaban and rivaroxaban) for extended VEnous Thromboembolism.
This pilot clinical trial compares the safety of two different platelet transfusion "thresholds" among patients with blood cancer or treatment-induced thrombocytopenia whose condition requires anticoagulant medication (blood thinners) for blood clots. Giving relatively fewer platelet transfusions may reduce the side effects of frequent platelet transfusions without leading to undue bleeding.
Prospective randomized open multicenter trial with blinded adjudication of endpoints to assess the efficacy of six-month low-dose LMWH (Low Molecular Weight Heparin) for the prevention of symptomatic or incidental VTE in patients with stage IV lung cancer and elevated D-dimer.
The PREVENTER Trial aims to compare the use of perioperative pharmacologic prophylaxis (subcutaneous heparin) with intermittent pneumatic compression devices (IPCs) to the use of IPCs alone for the prevention of venous thromboembolism (VTE) after radical prostatectomy (RP).
This study will assess the safety and effectiveness of a drug called apixaban for the treatment of upper extremity deep vein thrombosis (UEDVT) and clinically important bleeding. Subjects will receive apixaban 10 mg by mouth twice a day for 7 days, followed by 5 mg by mouth twice a day for a duration of 11 weeks. There will be a followup visit at 12 weeks for all participants. A total of 375 are to be enrolled. The study drug has been approved to treat blood clots. The study drug has not been studied uniquely for the treatment of blood clots in the upper extremity however. Because it is unknown whether it is effective to treat blood clots in the upper extremity, the principal investigator cannot guarantee that there will be benefit to study subjects; however, it is hoped that the information obtained from this research study will help treat patients in the future.
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.
Venous Thromboembolic Disease (VTE) in SCI patients is very common, its prevalence is 60 to 80% against 10-20% in the general population. The risk of VTE is very important in the first weeks after spinal cord injury, and then declines with a prevalence of VTE slightly higher than the general population after 12 weeks. However there is no prospective study of incidence of VTE in SCI patients after 3 months. The investigators wish to conduct such a study during the year following spinal cord injury with performing venous Doppler ultrasound of the lower limbs 6, 9 and 12 months of the initial injuryassociated with a standardized clinical assessment, to know the incidence of VTE and determine prognostic factors for VTE.
In renally impaired patients with acute venous thromboembolism (VTE), standard-of-care (SOC) anticoagulation, i.e. heparins-vitamin K antagonists (VKA), at therapeutic dosage is associated with an increased risk of thromboembolic and bleeding complications compared to patients with normal renal function. Direct oral anticoagulants (DOAs) have been shown to be at least as effective and safe as SOC in VTE treatment. But in the clinical trials, moderate renally impaired patients were poorly represented and patients with severe renal insufficiency not at all. So no dose reduction was considered. Surprisingly, DOAs have been approved for VTE treatment in moderate and severe renally impaired patients. There is need to evaluate a reduced dose of DOAs for VTE treatment in patients with moderate and severe renal insufficiency. We plan to evaluate reduced doses of 2 DOAs (apixaban, rivaroxaban) compared to SOC in VTE patients with moderate or severe renal insufficiency in terms of net clinical benefit (recurrent VTE and major bleeding) at 3 months.
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.
