- Percentage of patients with treatment failure at day 11 [ Time Frame: Day 11 after randomization ]defined as death, need of ICU and extracorporeal membrane oxygenation, need of non-invasive ventilation or nasal high-flow oxygen therapy, or worsening of the condition clinic of the patient during treatment (two of these: need to increase Fraction of inspired oxygen inspired>20%, need for fraction inspired oxygenation>50%, increase in respiratory rate>25, increase in inflammatory markers).
- Percentage of patients without the need for oxygen support at day 11. [ Time Frame: Day 11 after randomization ]
