Brief Summary:

There is emerging evidence that patients with SARS-CoV-2 are affected by increased coagulopathy, including in the most advanced forms, a fully blown disseminated intravascular coagulation, leading to multi organ failure (MOF). Post-Morten observations from patients who died because of SARS-CoV-2 infection in Bergamo, Italy and other places have revealed the presence of diffuse venous, arterial and microcirculatorythrombosis, not only restricted to the lung but also involving the kidneys, heart and gut.

Thrombin plays a central role in mediating clot forming as well as in mediating inflammation. A direct factor X inhibitor, namely edoxaban can act as prophylactic measure to mitigate the risk of venous and arterial thrombotic complications.

Colchicine is an inexpensive (generic drug), orally administered, and a potent anti-inflammatory medication. It might accelerate SARS-CoV-2 clearance.

The aim of the CONVINCE study is therefore to assess the safety and efficacy of edoxaban and/or colchicine administration in SARS-CoV-2 infected patients who are managed outside the hospital with respect to the occurrence of fatalities, hospitalisation, major vascular thrombotic events or the SARS-CoV-2 clearance rate under RT PCR.

Drug: Edoxaban Tablets

Drug: Colchicine Tablets

Primary Outcome Measures :
  1. Edoxaban vs. no active treatment [ Time Frame: Baseline to day 25 ]
    To assess the effect of edoxaban versus no active treatment on the composite endpoint of asymptomatic proximal deep-vein thrombosis, symptomatic proximal or distal deep-vein thrombosis, symptomatic pulmonary embolism or thrombosis, myocardial infarction, ischemic stroke, non-CNS systemic embolism or death at day 25 (+/-3) after randomization.

  2. Colchicine vs no active treatment [ Time Frame: Baseline to day 14 ]
    To assess the effect of colchicine versus no active treatment on the SARS-CoV-2 clearance rates under RT PCR or freedom from death or hospitalisation at day 14 (+/-3) after randomization.

Secondary Outcome Measures :
  1. Number of patients with asymptomatic proximal deep-vein thrombosis [ Time Frame: Baseline to day 25 ]
    An intraluminal filling defect on CT scan or MR venography in the IVC or iliac veins.

  2. Number of patients with symptomatic proximal or distal deep-vein thrombosis [ Time Frame: Baseline to day 25 ]
    Typical symptoms of DVT associated with non-compressible vein segment on ultrasonography or an intra-luminal filling defect on venography, CT venography or MRI venography,located in the inferior vena cava (IVC), the iliac vein, the common femoral vein, the femoral or the popliteal vein.

  3. Number of patient with symptomatic pulmonary embolism or thrombosis [ Time Frame: Baseline to day 25 ]

    Typical symptoms of PE associated with

    • an intra-luminal filling defect in (sub) segmental or more proximal branches on spiral computed tomography scan (CT) or computerized tomographic pulmonary angiography (CTPA).
    • a considerable perfusion defect (~ 75% of a segment) with a local normal ventilation result (high probability) during perfusion-ventilation lung scan (PLS, VLS or V/Q scan).
    • an intraluminal filling defect or a sudden cut-off of vessels (~more than 2.5 mm in diameter) on a catheter guided pulmonary angiogram.

    In case of an inconclusive CTPA, inconclusive V/Q scan or inconclusive angiography demonstration of DVT in the lower extremities e.g. by compression ultrasound or venography will be required

  4. Number of patients with myocardial infarction [ Time Frame: Baseline to day 25 ]
    For the primary analysis, MI endpoint will be defined based on the third universal definition of myocardial infarction with the exception of periprocedural MI after PCI, which will be defined according to the SCAI definition.

  5. Number of patients with ischemic stroke [ Time Frame: Baseline to day 25 ]
  6. Number of patients with non-CNS systemic embolism [ Time Frame: Baseline to day 25 ]
    Ischemic stroke is defined as an acute episode of focal cerebral, spinal, or retinal dysfunction caused by CNS infarction

  7. Number of deaths [ Time Frame: Baseline to day 25 ]
    Death will be classified in 5 categories with respect to cause. Thromboembolism, cardiovascular, bleeding, Pulmonary other known cause. In general, all deaths will be assumed to be due to thromboembolism or pulmonary in nature unless another cause is obvious

  8. Ventilation need [ Time Frame: Baseline to day 25 ]
    Need for non-invasive or invasive ventilation
