Brief Summary
Randomized, controlled study conducted in hospitalized patients with severe COViD-19 pneumonia and coagulopathy not requiring invasive mechanical ventilation. Aim of this study is to assess whether high doses of Low Molecular Weight Heparin (LMWH) (ie. Enoxaparin 70 IU/kg twice daily) compared to standard prophylactic dose (ie, Enoxaparin 4000 IU once day) are:
- 1.More effective to prevent clinical worsening, defined as the occurrence of at least one of the following events, whichever comes first, during hospital stay:
- 2.Death
- 3.Acute Myocardial Infarction \[AMI\]
- 4.Objectively confirmed, symptomatic arterial or venous thromboembolism \[TE\]
- 5.Need for either non-invasive - Continuous Positive Airway Pressure (Cpap) or Non-Invasive Ventilation (NIV) - or invasive mechanical ventilation for patients who are in standard oxygen therapy by delivery interfaces at randomisation
- 6.Need for invasive mechanical ventilation for patients who are in non-invasive mechanical ventilation at randomisation
- 7.Similar in terms of major bleeding risk during hospital stay

Eligibility Criteria
You may qualify if:
- Positive SARS-CoV-2 diagnostic (on pharyngeal swab of deep airways material)
- Severe pneumonia defined by the presence of at least one of the following criteria:
- Respiratory Rate ≥25 breaths /min
- Arterial oxygen saturation≤93% at rest on ambient air
- PaO2/FiO2 ≤300 mmHg
- Coagulopathy, defined by the presence of at least one of the following criteria:
- D-dimer \>4 times the upper level of normal reference range
- Sepsis-Induced Coagulopathy (SIC) score \>4
- No need for invasive mechanical ventilation
You may not qualify if:

- Known hypersensitivity to enoxaparin
- History of heparin induced thrombocytopenia

- Concomitant anticoagulant treatment for other indications (e.g. atrial fibrillation, venous thromboembolism, prosthetic heart valves).
- Concomitant double antiplatelet therapy
- Administration of therapeutic doses of LMWH, fondaparinux, or unfractionated heparin (UFH) for more than 72 hours before randomization; prophylactic doses are allowed
- Pregnancy or breastfeeding or positive pregnancy test
- Presence of other severe diseases impairing life expectancy (e.g. patients are not expected to survive 28 days given their pre-existing medical condition)
- Lack or withdrawal of informed consent

- Masking Details
- Randomisation will be centrally performed by using a secure, web-based system, which will be developed by the Methodological and Statistical Unit at the Azienda Ospedaliero-Universitaria of Modena. Randomisation stratified by 4 factors: 1) Gender (M/F); 2) Age (\<75/≥75 years); 3) BMI (\<30/≥30); 4) Co-morbidities (0-1/\>2) with random variable block sizes will be generated by STATA software. The web-based system will guarantee the allocation concealment.
