There are 12 clinical trials
The ongoing COVID-19 pandemic affects millions of humans worldwide and has led to thousands of acute medical hospitalizations. There is evidence that hospitalized cases often suffer from an important infection-related coagulopathy and from elevated risks of thrombosis. Anticoagulants may have positive effects here, to reduce the burden of thrombotic disease and the hyperactivity of coagulation, and may also hold beneficial anti-inflammatory effects against sepsis and the development of ARDS. The investigators hypothesize that high-dose anticoagulants, compared with low-dose anticoagulants, lower the risk of venous and arterial thrombosis, disseminated intravascular coagulation (DIC) and mortality. This open-label controlled trial will randomize hospitalized adults with severe COVID-19 infection to therapeutic anticoagulation vs. thromboprophylaxis during the hospital stay.

Measure: Number of pulmonary embolism events Time: 30 daysWorldwide observational studies indicate a significant prothrombogenic effect associated with SARS-CoV-2 infection with a high incidence of venous thromboembolism (VTE), notably life-threatening pulmonary embolism. According to recommendations for acute medical illnesses, all COVID-19 hospitalized patients should be given VTE prophylaxis such as a low molecular weight heparin (LMWH). A standard prophylactic dose (eg. Enoxaparin 4000IU once daily) could be insufficient in obese patients and VTE has been reported in patients treated with a standard prophylactic dose. In COVID-19 patients, guidelines from several international societies confirm the existence of an hypercoagulability and the importance of thromboprophylaxis but the "optimal dose is unknown" and comparative studies are needed. In view of these elements, carrying out a trial comparing various therapeutic strategies for the prevention of VTE in hospitalized patients with COVID-19 constitutes a health emergency. Thus, we hypothesize that an increased prophylactic dose of weight-adjusted LMWH would be greater than a lower prophylactic dose of LMWH to reduce the risk of life-threatening VTE in hospitalized patients. The benefit-risk balance of this increase dose will be carefully evaluated because of bleeding complications favored by possible renal / hepatic dysfunctions, drug interactions or invasive procedures in COVID-19 patients. This multicenter randomized (1:1) open-label controlled trial will randomize hospitalized adults with COVID-19 infection to weight-adjusted prophylactic dose vs. lower prophylactic dose of LMWH.

Measure: Factors associated with the risk of venous thromboembolism Time: 28 daysThe coronavirus disease 2019 (COVID-19) global pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused considerable morbidity and mortality in over 170 countries. Increasing age and burden of cardiovascular comorbidities are associated with a worse prognosis among patients with COVID-19. In addition, serologic markers of more severe disease including coagulation abnormalities and thrombocytopenia, are not uncommon among patients hospitalized with severe COVID-19 infection and are more common in patients who died in-hospital. As the COVID-19 pandemic continues to grow, there is a pressing need to identify safe, effective, and widely available therapies that can be scaled and rapidly incorporated into clinical practice. Understanding the putative mechanism of increased mortality risk associated with abnormal coagulation function and cardiac injury is critical to guide studies of promising therapeutic interventions. Published and anecdotal reports indicate that endothelial dysfunction and thrombosis are common in critically ill patients with COVID-19, including reports of diffuse microvascular thrombosis in the lungs, heart, liver, and kidneys. Patients with cardiovascular disease (CVD) and CVD risk factors are known to have endothelial dysfunction and a heightened risk of thrombosis. A recent study of COVID-19 inpatients from Wuhan, China observed that an elevated D-dimer level greater than 1 ug/mL was associated with an 18 times higher risk of in-hospital death, underscoring the importance of increased coagulation activity as a potential modifiable risk marker that may drive end-organ injury. Given the established link between endothelial dysfunction and thrombosis in patients with cardiovascular disease, and the association between coagulopathy and adverse outcomes in patients with sepsis, the association between increased coagulation activity, end-organ injury, and mortality risk may represent a modifiable risk factor among COVID-19 patients with critical illness. Therefore, we propose to conduct a randomized, open-label trial of therapeutic anticoagulation in COVID-19 patients with an elevated D-dimer to evaluate the efficacy and safety.

Measure: Number of documented venous thromboembolism or arterial thrombosis Time: 3 monthsEvidence has shown that COVID-19 infections can lead to an increased risk of blood clots. These blood clots can lead to individuals being admitted to hospital, or, unfortunately in severe cases, death. Enoxaparin is a blood-thinning drug which has been used by doctors and nurses in hospitals for many years to prevent the thickening of blood which may lead to a clot. It is easier for doctors to prevent new blood clots from forming than treating existing blood clots. Currently, there are no treatments for COVID-19. There is an urgent need to find a safe and effective treatment to prevent worsening of the disease that may lead to hospital admission and/or death. The ETHIC (Early Thromboprophylaxis in COVID-19) study aims to find out if giving enoxaparin in an early stage of the COVID-19 disease can prevent individuals being admitted to hospital and/or death. The study will take place in approximately 8 to 10 countries, in approximately 30 to 50 centres. Patients will be allowed to take part if they have had a confirmed COVID-19 infection, are ≥ 55 years of age and have at least two of the following additional risk factors; age ≥ 70 years, body mass index > 25 kg/m2, chronic obstructive pulmonary disease, diabetes, cardiovascular disease, or corticosteroid use. Half the patients in the study will receive the blood-thinning drug enoxaparin for three weeks, and half will receive no treatment. Individuals will be randomly allocated to one of these groups. After 21 days, the number of patients in each group who were either admitted to hospital, or died, will be compared. The number of patients in each group who developed a blood clot (venous thromboembolism) will also be compared. Further comparisons will be made at both 50 and 90 days after the beginning of the study.

Measure: Diagnosis of VTE Time: 21, 50 and 90 daysViral infections provoke the systemic inflammatory response and cause an imbalance between the procoagulant and anticoagulant homeostatic mechanisms. Multiple pathogenic mechanisms are involved, including endothelial dysfunction, increased von Willebrand factor, Toll receptor activation, and tissue factor pathway activation. D-dimer levels greater than 1000 ng / mL are associated with an 18-fold increased risk of mortality. In this context, many patients may require prophylaxis or antithrombotic treatment with low molecular weight heparins. Currently, there is no validated scheme on the dose and timing of the use of antithrombotic drugs. The study aims to identify the effect of two anticoagulant strategies (prophylactic and therapeutic) on the progression to ventilatory support or death in patients with COVID-19 infection who require hospital care.

Measure: low molecular weight heparin (enoxaparin) and mortality rate Time: 30 daysCoronavirus Disease (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has led to unprecedented morbidity and mortality in the modern era. To date, nearly 13 million people have contracted COVID-19, leading to more than 550,000 deaths worldwide. As the number of affected individuals continues to climb, effective strategies for treatment and prevention of the disease are of paramount importance. SARS-CoV-2 is understood to directly invade cells via the human angiotensin-converting enzyme 2 (ACE2) receptor, which is expressed predominantly in the lungs but also throughout the cardiovascular system. Thus, while acute respiratory distress syndrome remains a feared complication, new thromboembolic disease has emerged as a common and potentially catastrophic manifestation of COVID-19.
