Brief Summary

SINGLE CENTER PHASE III INTERVENTIONAL RANDOMIZED CONTROLLED TRIAL comparing efficacy and safety of enoxaparin at prophylactic dose (standard treatment) and enoxaparin at therapeutic dose (OFF-LABEL treatment) in 300 COVID-19 infected patients with moderate-severe respiratory failure (PaO2/FiO2\<250) and/or increased D-dimer levels enrolled in different Units (Infectious disease, Internal Medicine, Emergency Medicine, Pneumology) of Azienda Socio Sanitaria Territoriale Fatebenefratelli Sacco (ASST-FBF-SACCO).

Outcome Measures

Primary Outcomes (5)

  • Mortality rate

    Mortality registered during the time frame

    30 days from enrollment

  • Progression of respiratory failure

    Progression of respiratory failure defined as duration of continuous positive pressure ventilation (CPAP)

    30 days from enrollment

  • Progression of respiratory failure

    Progression of respiratory failure defined as percentage of patients admitted to ICU

    30 days from enrollment

  • Progression of respiratory failure

    Progression of respiratory failure defined as percentage of patients undergoing oro-tracheal intubation

    30 days from enrollment

  • Number of major bleeding episodes

    Major bleeding (ISTH criteria) and/or clinically relevant non-major bleeding

    up to 6 months from randomization

Secondary Outcomes (4)

    at 72 hours

  • Respiratory function improvement

    1 week from randomization

  • Number of major cardiovascular events

    6 months from randomization

  • Deep Vein Thrombosis

    6 months from randomization

Study Arms (2)

Enoxaparin at prophylactic dose

ACTIVE COMPARATOR

Enoxaparin at prophylactic dose: standard 4.000 IU QD via subcutaneous injection (6000 IU if body weight\>100 kg)

Drug: Enoxaparin

Enoxaparin at therapeutic dose

EXPERIMENTAL

Enoxaparin at therapeutic dose : 70 U/Kg b.i.d. (every 12 h) In order to easily calculate the correct therapeutic dose of enoxaparin for each patient, a simplified categorization will be applied, as follows: * weight \< 65 Kg: 4.000 IU b.i.d. (every 12 h) * weight ≥ 65 Kg: 6.000 IU b.i.d. (every 12 h) * weight ≥ 100 Kg: 8.000 IU b.i.d. (every 12 h) The most appropriate dose will be evaluated in patients with creatinine clearance between 30 and 50 ml/min

Drug: Enoxaparin

Interventions

subcutaneous injections
