E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome variable will be the number of ventilator-free days defined as the number of days the patient is not receiving mechanical ventilation during the 21 days after randomisation. Mechanical ventilation will be defined as invasive and non-invasive. Patient will be defined free of mechanical ventilation after 12 hours from the suspension of any type of both invasive and non-invasive ventilation. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Starting from the 21 days after ranfomization |
|
E.5.2 | Secondary end point(s) |
- Number of free days from invasive ventilation - Number of free days from non-invasive ventilation (NIV) - Change from baseline in PaO2/FiO2 ratio at 6 and 12 hours following each dose administration in the treated group relative timepoints in the control group (6, 12, 30, 36, 54 and 60 hours after randomisation) - Change from baseline in PaO2/FiO2 ratio at additional timepoints (i.e. every 24 hours since treatment/randomisation till the patient is discharged from the ICU) - Percentage of patients with PaO2/ FiO2 improvement >20% at 6 and 12 hours following each dose administration in the treated group and relative timepoints in the control group (6, 12, 30, 36, 54 and 60 hours after randomisation) - Percentage of patients with PaO2/ FiO2 improvement >20% at additional timepoints (i.e. every 24 hours after treatment/randomisation till the patient is discharged from the ICU) - Change from baseline in FiO2 at 6 and 12 hours following each dose administration in the treated group and relative timepoints in the control group (6, 12, 30, 36, 54 and 60 hours after randomisation) - Change from baseline in FiO2 at additional timepoints (i.e. every 24 hours after treatment/randomisation till the patient is discharged from the ICU) - Length of ICU stay (days) - Mortality at Day 28 - Delta SOFA Score measured on Day 3 at Discharge and Day 28 - Change from baseline in ventilatory parameters [tidal volume (TV), respiratory rate (RR), dynamic compliance (Cdyn), static compliance (Cstat), positive end-expiratory pressure (PEEP), peak inspiratory pressure (PIP), plateau pressure (Pplat)] measured at 6-12-24h after each administration or randomisation up to 72 hours and then every 24 hours till the patient is discharged from the ICU. - Change from baseline in blood gas analysis acid-base balance parameters (i.e. pH, pCO2, pO2, HCO3, lactate) measured at 6-12-24h after each administration or randomisation up to 72 hours and then every 24 hours till the patient is discharged from the ICU. - Number of Extracorporeal Membrane Oxygenation (ECMO)-free days during the 21 days after randomisation, defined as the number of days the patient is not receiving ECMO (ECMO cohort)
