Trial Outcomes

28-Day Mortality

Outcome reported as the number of participants who have expired at 28 days post enrollment. (NCT04312009)
Timeframe: 28 days

Interventionproportion of participants (Number)
Placebo0.087

90-Day Mortality

Outcome reported as the number of participants who have expired at 90 days post enrollment. (NCT04312009)
Timeframe: 90 days

Interventionproportion of participants (Number)
Placebo0.106

Change in Viral Load by Nasopharyngeal Swab Day 15

Nasopharyngeal swabs will be collected at baseline and day 15. Viral load is measured as number of viral genetic copies per mL. (NCT04312009)
Timeframe: 15 days

Interventionlog10 copies/mL (Mean)
Placebo-4.2
Losartan-4.8

Daily Hypotensive Episodes

Outcome reported as the mean number of daily hypotensive episodes (MAP < 65 mmHg) prompting intervention (indicated by a fluid bolus >=500 mL) per participant in each arm. (NCT04312009)
Timeframe: 10 days

Interventionepisodes per day (Mean)
Placebo0.048

Difference in Estimated (PEEP Adjusted) P/F Ratio at 7 Days

Outcome calculated from the partial pressure of oxygen or peripheral saturation of oxygen by pulse oximetry divided by the fraction of inspired oxygen (PaO2 or SaO2 : FiO2 ratio). PaO2 is preferentially used if available. A correction is applied for endotracheal intubation and/or positive end-expiratory pressure. Patients discharged prior to day 7 will have a home pulse oximeter send home for measurement of the day 7 value, and will be adjusted for home O2 use, if applicable. Patients who died will be applied a penalty with a P/F ratio of 0. (NCT04312009)
Timeframe: 7 days

Disease Severity Rating

Outcome reported as the number of participants in each arm who fall into each of 7 categories. Lower scores indicate greater condition severity. The ordinal scale is an assessment of the clinical status at the first assessment of a given study day. The scale is as follows: 1) Death; 2) Hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); 3) Hospitalized, on non-invasive ventilation or high flow oxygen devices; 4) Hospitalized, requiring supplemental oxygen; 5) Hospitalized, not requiring supplemental oxygen; 6) Not hospitalized, limitation on activities; 7) Not hospitalized, no limitations on activities.

Oxygen Saturation / Fractional Inhaled Oxygen (S/F)

Oxygen saturation (percent) is measured by pulse oximeter. Fraction of inspired oxygen (FiO2) (unitless) is the volumetric fraction of oxygen to other gases in respiratory support. The S/F ratio is unitless. (NCT04312009)
Timeframe: 7 days
