Clinical Trial of Dimolegin (DD217) in Prevention of Thrombotic Complications in Patients With COVID-19...
COVID-19Venous ThromboembolismStudy purpose was to study the safety and efficacy of Dimolegin - DD217 as a drug for prevention of thrombotic complications compared to Clexane (enoxaparin sodium) - the standard therapy currently prescribed to patients hospitalized with COVID-19. Patients who met all inclusion criteria and no exclusion criteria were randomized into two therapy groups: Group 1 - test drug Dimolegin - DD217 (60 mg orally, 1 time per day); Group 2 - reference drug Clexane (40 mg subcutaneously, 1 time per day). The study drugs were taken once a day until: the discharge from the hospital due to recovery or positive dynamics; or up to 30 days of the patient's stay in the hospital; or until the Investigator decides to discontinue the therapy for other reasons. Planned: screening of up to 450 patients, randomization: 430 (215 per group). The required number of patients is 200 per group as a result of the entire study.
Graduated Compression Stockings (GCS) Pilot Substudy
Venous ThromboembolismThis is a pilot substudy to the PeriOperative ISchemic Evaluation-2 Trial (POISE-2), to assess the feasibility of adding graduated compression stockings (GCS) to POISE-2 as an intervention.
Remote Home Prothrombin Time (PT)/International Normalized Ratio (INR) Monitoring and Patient Management...
Venous ThromboembolismLong-term anticoagulation is indicated in patients for the prophylaxis and/or treatment of the thromboembolic complications associated with atrial fibrillation and/or mechanical cardiac valve replacement, prevention or treatment of venous thromboembolism (deep vein thrombosis and pulmonary embolism), to prevent thromboembolic events post-myocardial infarction, and in patients with systemic embolic events. Currently the only approved oral medication for anticoagulation is warfarin (Coumadin, Bristol-Myers Squibb and generic warfarin. Dosage is controlled by periodic determinations of the prothrombin time (PT)/International Normalized Ratio (INR). Under treatment may lead to venous or arterial thrombotic events or stroke, while over treatment may lead to major bleeding and even death. Patients require frequent INR monitoring to maintain a therapeutic level of anticoagulation. The therapeutic INR range varies by clinical indication, most commonly an INR 2-3 goal, but ranging from 1.5-4.0. Bleeding complications are more likely to occur above an INR value of 4.0. The vMetrics - Anticoagulation Management System is a remote patient management solution for Oral Anticoagulation Care patients. This system provides confirmation of patient question and testing protocols as well as virtual patient management care capability for dosage and patient scheduling. This trial will provide end points to ascertain efficiency against standard care protocol and confirm equivalent care standards.
A Study of Dalteparin Prophylaxis in High-Risk Ambulatory Cancer Patients
Venous ThromboembolismPulmonary EmbolismSome cancer patients starting a new chemotherapy regimen are likely to develop blood clots, also known as venous thromboembolism (VTE). Blood clots can cause symptoms and can occasionally be life-threatening. The purpose of this study is to determine if a daily injection of a blood-thinner, dalteparin, for 12 weeks can safely and effectively reduce the frequency of blood clots. Dalteparin is currently approved for prevention of blood clots following surgery and in hospitalized patients but not specifically for cancer outpatients.
Prothrombin Times Outside the Therapeutic Range in Otherwise Stable Patients
Atrial FibrillationVenous Thromboembolism2 moreWarfarin is very effective for the prevention of blood clots (thrombosis). A test of coagulation, the prothrombin time (PT) is used to monitor the effect. The PT response to warfarin can fluctuate as a result of interactions with a large number of other drugs, food or herbal agents as well as for no apparent reason. Thus, frequent monitoring of the PT and dose adjustments according to the results are required. One third of our patients remain on the same maintenance dose over 6 months. However, also these patients sometimes have a PT result moderately outside the therapeutic range without any obvious explanation. Too short PTs may be due to missed dose(s) or more dark green vegetables in the diet. Too long PTs may be due to a course of antibiotic therapy or less dark green vegetables. Laboratory errors may also occur and can cause deviations in any direction. Most likely, unnoticed fluctuations in the PT occur as well between the time points of monitoring. There are no guidelines on how to manage the treatment in this situation but there are some typical "behaviours". Behavior A: Some physicians simply let the patient continue with the same dose. "It is extremely unlikely that the very temporary dose adjustment has any effect on the PT result 4 weeks later and this is a "cosmetic procedure"." Behavior B: Others recommend the patients to take ½ - 1 additional dose in case of short PT and to skip a dose or take half dose in case of long PT, and thereafter to continue with the usual dose. "The investigators need to quickly correct the temporary aberration in order to avoid thrombotic or bleeding complications the next few days. This may seem like an issue of no importance. The investigators are however performing a series of studies to evaluate if these stable patients can be managed with blood tests less often than every 4 weeks. For that purpose it is important to know how often and why aberrant results occur, the implication and to what extent they can be ignored. The investigators hypothesis is that in patients with very stable PT-results and unchanged dose for 3 months, should continue with exactly the same maintenance dose, even when the result unexpectedly is slightly above or below the therapeutic range. The investigators believe that most of these occasional PT-results outside the therapeutic range are due to laboratory errors, perhaps missed doses by the patient or temporary change in diet or medications.

Hokusai Study in Pediatric Patients With Confirmed Venous Thromboembolism (VTE)
Venous Thromboembolism (VTE)Pulmonary Embolism1 moreThis is an event driven Phase 3, prospective, randomized, open-label, blinded endpoint evaluation (PROBE) parallel group study in subjects with confirmed VTE. This study is designed to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of edoxaban and to compare the efficacy and safety of edoxaban against standard of care in pediatric subjects with confirmed VTE.
Direct Oral Anticoagulants (DOACs) Versus LMWH +/- Warfarin for VTE in Cancer
CancerVenous Thromboembolism3 moreThe overarching objective of the study is to determine the effectiveness of LMWH/ warfarin vs. DOAC anticoagulation for preventing recurrent VTE in cancer patients. The intervention strategy is Direct Oral AntiCoagulants (DOAC) therapy with edoxaban, apixaban, rivaroxaban, or dabigatran. The comparator is low molecular weight heparin (LMWH) alone or with warfarin. The information gained will empower cancer patients and physicians to make more informed choices about anticoagulation strategies to manage VTE.
PREvention of VENous Thromboembolism In Hemorrhagic Stroke Patients
Hemorrhagic StrokeVenous Thromboembolism1 morePatients with cerebral hemorrhage (ICH) have a high risk of venous thromboembolism. Intermittent pneumatic compression combined with elastic stockings have been shown to be superior to elastic stockings alone in reducing the rate of asymptomatic deep vein thrombosis after ICH in a randomized trial (4.7% vs. 15.9%). Graduated compression stockings alone are ineffective in preventing deep vein thrombosis in patients with ischemic or hemorrhagic stroke. Less clear is the role of anticoagulation in the prevention of venous thromboembolism in patients with ICH because the use of anticoagulants may cause an enlargement of the hematoma. In a multicenter, randomized trial, the investigators will assess the efficacy and safety of enoxaparin in the prevention of venous thromboembolism in patients with spontaneous intracerebral hemorrhage. Enoxaparin (40 mg once daily) or standard therapy (graduated compression stockings and/or intermittent pneumatic compression and/or early mobilization) will be given subcutaneously for not less than 10 days beginning after 72 hours from stroke onset.
