- Evaluation of clinical status [ Time Frame: Day 15 of the trial ]Evaluation of clinical status of patients on day 15 after randomization, defined by the Ordinal Scale of 7 points (score ranges from 1 to 7, with 7 being the worst score)
- All-cause mortality [ Time Frame: 29 days after the randomization ]All-cause mortality from randomization to day 28
- Hospital Mortality [ Time Frame: 29 days after the randomization ]Deaths that occur during hospital admission.
- Improvement of Sequential Sepsis-related Organ Failure Assessment (SOFA) scale [ Time Frame: 29 days after the randomization (evaluations at D8 and D15) ]Improvement of SOFA scale of patients at day 8, 15 and 29 after randomization
- Evaluation of clinical status [ Time Frame: 29 days after the randomization (evaluations at D8 and D29) ]Evaluation of clinical status of patients on the day 8, 22 and 29 after randomization, defined by the Ordinal Scale of 7 points (score ranges from 1 to 7, with 7 being the worst score)
- Ventilator free days [ Time Frame: 29 days after the randomization ]Days alive and free from mechanical ventilation since randomization
- Time until oxygen support independence [ Time Frame: 29 days after the randomization ]Days from randomization to independence of oxygen support
- Need of mechanical ventilation support [ Time Frame: 29 days after the randomization ]Number of patients that were not at mechanical ventilation at randomization and that required that support.
- Days to mechanical ventilation support. [ Time Frame: 29 days after the randomization ]
Number of days to mechanical ventilation for patients that were not receiving it at randomization.
For patients that were not in mechanical ventilation at randomization: number of days until that support was required.
- Duration of hospitalization [ Time Frame: 29 days after the randomization ]Lenght of hospitalization stay in survivors (in days)
- Other infections [ Time Frame: 29 days after the randomization ]Incidence of other infections (aside from SARS-CoV 2)
- Incidence of thromboembolic events [ Time Frame: 29 days after the randomization ]Incidence of thromboembolic events in patients with COVID-19
- Incidence of adverse events [ Time Frame: 29 days after the randomization (specific evaluations at D8, D15 and D29) ]Evaluation of adverse events, as well as serious and unexpected adverse events
- Correlation of inflammatory tests and cytokines with clinical outcomes [ Time Frame: 29 days after the randomization ]Correlation of inflammatory tests and cytokines with clinical outcomes: clinical status (ordinal scale), time to oxygen support independence, ventilator free days, need of mechanical ventilation and mortality
- Exploratory evaluation of laboratory exams during hospitalization [ Time Frame: 29 days after the randomization ]Evaluation the kinetics of hemostasia exams, inflammatory tests, cytokines, flow cytometry of blood cells, CBC, renal and liver exams
- Evaluation of viral clearance of SARS-CoV2 [ Time Frame: Day 8 and 15 after randomization ]Evaluation of viral clearance of SARS-CoV2 using RT-PCR analysis of nasopharyngeal swab
