Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to Improvement in Clinical Status of Participants (Using 7-point Ordinal Scale Score) by at Least 2 Points	Time to improvement of greater than or equal (>=) 2 points in clinical status assessment was defined as time (in days) from first dose of study drug to the time of first occurrence of improvement of >=2 points in clinical status of participants assessed using 7-point ordinal scale (calculated as: Date of first occurrence/episode of the event - date of first dose + 1). Seven-point ordinal scale for clinical assessment ranges from 1= death; 2= hospitalized, on invasive mechanical ventilation/ECMO; 3= hospitalized, on non-invasive ventilation/high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5= hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related/otherwise); 6= hospitalized, not requiring supplemental oxygen - no longer required ongoing medical care; 7= not hospitalized, higher score = less severity. Kaplan-Meier method was used for analysis.	Baseline to Day 29
Secondary	Percentage of Participants Who Were Alive at Day 29	Percentage of participants who were alive at Day 29 were reported in this outcome measure.	Day 29
Secondary	Percentage of Participants With Improvement in Clinical Status (According to 7-point Ordinal Scale Score) by at Least 1 Point From Baseline at Days 4, 7, 15, 21, and 29	Clinical status of participants was assessed using 7-point ordinal scale ranges from: 1= death; 2= hospitalized, on invasive mechanical ventilation/ECMO; 3= hospitalized, on non-invasive ventilation/high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5= hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related/otherwise); 6= hospitalized, not requiring supplemental oxygen - no longer required ongoing medical care; 7= not hospitalized, higher score=less severity. Percentage of participants With >=1 point improvement in clinical status from Baseline at Days 4, 7, 15, 21, and 29 (assessed using the 7-point ordinal scale) were reported.	Baseline, Days 4, 7, 15, 21, and 29
Secondary	Change From Baseline at Days 4, 7, 15, 21, 29 in 7-point Ordinal Scale Score	Clinical status of participants was assessed using 7-point ordinal scale ranges from: 1= death; 2= hospitalized, on invasive mechanical ventilation/ECMO; 3= hospitalized, on non-invasive ventilation/high flow oxygen devices; 4= hospitalized, requiring supplemental oxygen; 5= hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related/otherwise); 6= hospitalized, not requiring supplemental oxygen - no longer required ongoing medical care; 7= not hospitalized, higher score=less severity.

Time to resolution of fever (in days) was calculated as: date of first occurrence/episode of the event (resolution of fever) - date of first dose + 1. Kaplan-Meier method was used for estimation.	Baseline to Day 29
Secondary	Time to Resolution of Fever and Improvement in Oxygenation	Time to resolution of fever was defined as body temperature <=36.6°C (axilla), or <=37.2 °C (oral), or <=37.8°C (rectal or tympanic) for at least 48 hours without antipyretics or until discharge, whichever was sooner. Improvement in oxygenation was defined as oxygen saturation (SpO2)/FiO2 of 50 or greater compared to the nadir SpO2/FiO2 for at least 48 hours, or until discharge, whichever was sooner. Nadir SpO2/FiO2 was the nadir (lowest value) at any point in the study. Time to resolution of fever and improvement in oxygenation (in days) was calculated as: date of first occurrence/episode of the event (resolution of fever and improvement in oxygenation) - date of first dose + 1. Kaplan-Meier method was used for estimation.	Baseline to Day 29
Secondary	Number of Days With Fever	Fever was defined as body temperature greater than (>) 37.4°C (axilla), or >38.0 °C (oral), or >38.4°C (rectal or tympanic) based on maximum value observed during a 24-hour period. Number of days with fever were reported. Least square (LS) mean and standard error (SE) were estimated using the analysis of covariance (ANCOVA) model with treatment group and randomization strata as fixed effects.	Baseline to Day 29
Secondary	Percentage of Participants in Each National Early Warning Score 2 (NEWS2) Clinical Risk Category at Baseline and at Days 4, 7, 15, 21, and 29	NEWS2: used to standardize assessment of acute-illness severity, track clinical condition of participants and to alert clinical teams to participant deterioration. NEWS2 score was based on 7 clinical parameters: respiration rate, oxygen saturation, supplemental oxygen, systolic blood pressure, pulse rate, level of consciousness, and temperature. A score of 0, 1, 2, and 3 was allocated to each parameter except supplemental oxygen (a score of 0 or 1 was allocated) and level of consciousness (a score of 0 or 3 was allocated), where 0 = normal health condition to 3 = worst health condition; higher score indicated more severity. All scores were summed to get an aggregate score. Aggregate NEWS2 score ranged from 0 to 19, with higher scores meaning more severity/higher risk. Percentage of participants in following clinical risk categories were reported: low risk (score 0 to 4); low to medium risk (score of 3 in any individual parameter); medium risk (score 5 to 6); high risk (score 7 to 19).

NEWS2 score was based on 7 clinical parameters: respiration rate, oxygen saturation, supplemental oxygen, systolic blood pressure, pulse rate, level of consciousness, and temperature. A score of 0, 1, 2, and 3 was allocated to each parameter except supplemental oxygen (score of 0 or 1 was allocated) and level of consciousness (score of 0 or 3 was allocated), where 0=normal health condition to 3=worst health condition; higher score=more severity. All scores were summed to get an aggregate score which ranged from 0 to 19, with higher scores=more severity/higher risk. Kaplan-Meier method was used for analysis.	Baseline to Day 29
Secondary	Change From Baseline at Days 4, 7, 15, 21, and 29 in National Early Warning Score 2	The NEWS2 was used to standardize the assessment of acute-illness severity, track the clinical condition of participants, and to alert clinical teams to participant deterioration. NEWS2 score is based on 7 clinical parameters: respiration rate, oxygen saturation, supplemental oxygen, systolic blood pressure, pulse rate, level of consciousness, and temperature. A score of 0, 1, 2, and 3 was allocated to each parameter except supplemental oxygen (a score of 0 or 1 was allocated) and level of consciousness (a score of 0 or 3 was allocated), where 0 = normal health condition to 3 = worst health condition; higher score indicated more severity. All scores were summed to get an aggregate score. Aggregate NEWS2 score ranged from 0 to 19, with higher scores meaning more severity/higher risk. LS means and SE were estimated using ANCOVA model with treatment group and randomization strata as fixed effects, and baseline NEWS2 score as a covariate.	Baseline, Days 4, 7, 15, 21, and 29
Secondary	Time-to-improvement in Oxygenation	Time-to-improvement in oxygenation was defined as increase in SpO2/FiO2 of 50 or greater compared to the nadir SpO2/FiO2 for at least 48 hours or until discharge, whichever was sooner. Nadir SpO2/FiO2 was the nadir (lowest value) at any point in the study. Time to improvement in oxygenation was calculated as: date of first occurrence/episode of the event (oxygenation) - date of first dose + 1. Kaplan-Meier method was used for estimation.	Baseline to Day 29
Secondary	Percentage of Participants Alive Off Supplemental Oxygen at Day 29	Supplemental oxygen was defined as oxygen administration by nasal cannula, simple face mask, or other similar oxygen delivery device.	Day 29
Secondary	Percentage of Days With Hypoxemia	Hypoxemia (low level of oxygen in the blood) was defined as SpO2 <93% on room air, or required supplemental oxygen, or mechanical ventilatory support.

LS mean and SE were estimated using the ANCOVA model with treatment group and randomization strata as fixed effects.	Baseline to Day 29
Secondary	Time to Oxygen Saturation >= 94% on Room Air	Time to oxygen saturation >=94% on room air was defined as the time (in days) from first dose of study drug until the time of first occurrence of oxygen saturation >=94% and it was calculated as: Date of first occurrence/episode of the event (oxygen saturation >=94%) - date of first dose + 1.Kaplan-Meier method was used for estimation.

Treatment-emergent AEs (TEAEs) were the AEs that developed or worsened or became serious during the TEAE period (from the time of first dose of study drug to the last dose of study drug + 60 days).
