Percentage of Participants With a Change in Oxygen Saturation From < 94% to ≥ 94% From BaselineDay 10Percentage of participants with a change in oxygen saturation from \< 94% to ≥ 94% from baseline based on National Early Warning Score (NEWS). Measure of the oxygen level of the blood is measure by pulse oximetry. The score is determined from six physiological parameters readily measured over time in hospitalized participants: Respiration rate; oxygen saturation; temperature; systolic blood pressure; heart (pulse) rate, and level of consciousness, as measured by Alert Voice Pain Unresponsive (AVPU). A score is assigned to each parameter, the magnitude of the score representing the extremity of variation from the norm. A weighting score is added for participants needing supplemental oxygen (oxygen delivery by mask or by cannula) The aggregate score is reflective of the participants status.
Overall MortalityDay 1 to Day 28Number of deaths by Day 28.
Percentage of Participants With at Least 1-Point Improvement on National Institute of Allergy and Infectious Diseases Ordinal Scale (NIAID-OS) or Live Discharge From HospitalDay 10The National Institute of Allergy and Infectious Diseases ordinal scale (NIAID-OS) is an assessment of clinical status. The scale is as follows: 1) Not hospitalized, no limitations on activities; 2) Not hospitalized, limitation on activities and/or requiring home oxygen; 3) Hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 4) Hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 5) Hospitalized, requiring supplemental oxygen; 6) Hospitalized, on non-invasive ventilation or high-flow oxygen devices; 7) Hospitalized, on invasive mechanical ventilation or ECMO; 8) Death. Participants with missing baseline ordinal scale values were excluded from analysis.
Time to Clinical Deterioration (One-category Increase on the NIAID-OS)Day 1 to Day 28The National Institute of Allergy and Infectious Diseases ordinal scale (NIAID-OS) is an assessment of clinical status. The scale is as follows: 1) Not hospitalized, no limitations on activities; 2) Not hospitalized, limitation on activities and/or requiring home oxygen; 3) Hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 4) Hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 5) Hospitalized, requiring supplemental oxygen; 6) Hospitalized, on non-invasive ventilation or high-flow oxygen devices; 7) Hospitalized, on invasive mechanical ventilation or ECMO; 8) Death. A higher score is representative of worse clinical outcome with a score of 8 being the highest and representing death.
Time to Resolution of Fever in Participants With Fever at BaselineDay 1 to Day 28Time to resolution of fever in participants with fever at baseline was calculated using cox proportional hazard regression model adjusted for baseline disease severity (OS 4, OS 5, OS 6), age (\<65 years, \>=65 years), region (United States, Europe, rest of world), and systemic corticosteroids used at baseline for primary study condition (Yes/No).
Mean Change From Baseline on the National Early Warning Score (NEWS)Baseline, Day 4; Baseline, Day 7; Baseline, Day 10; Baseline, Day 14The NEWS score is used to detect and report changes in illness severity in participants with acute illness to identify participants at risk for poor outcomes. The score is based on six physiological parameters (Respiration rate; oxygen saturation; temperature; systolic blood pressure; heart (pulse) rate, and level of consciousness). A score is assigned to each parameter, and the sum of the score represents the participant's risk of poor outcomes with a minimum score of 0 representing the better outcome, a score of 7 or greater reflects high clinical risk for worsening and maximum score of 19 representing the worse outcome.
Time to Definitive ExtubationDay 1 to Day 28Time to definitive extubation included participants who progressed to OS 7 at any time prior to Day 28.
Time to Independence From Non-Invasive Mechanical VentilationDay 1 to Day 28Time to independence from non-invasive mechanical ventilation was measured in days among participants who required non-invasive ventilation.

Percentage of Participants With a Change in Oxygen Saturation From < 94% to ≥ 94% From Baseline

Percentage of participants with a change in oxygen saturation from \< 94% to ≥ 94% from baseline based on National Early Warning Score (NEWS). Measure of the oxygen level of the blood is measure by pulse oximetry. The score is determined from six physiological parameters readily measured over time in hospitalized participants: Respiration rate; oxygen saturation; temperature; systolic blood pressure; heart (pulse) rate, and level of consciousness, as measured by Alert Voice Pain Unresponsive (AVPU). A score is assigned to each parameter, the magnitude of the score representing the extremity of variation from the norm. A weighting score is added for participants needing supplemental oxygen (oxygen delivery by mask or by cannula) The aggregate score is reflective of the participants status.

Time frame: Day 10

Population: All participants randomly assigned to study intervention whose oxygen saturation (based on National Early Warning Score) is \< 94% at baseline and have non-missing baseline and at least 1 postbaseline observation are in this population.

Time to Clinical Deterioration (One-category Increase on the NIAID-OS)

The National Institute of Allergy and Infectious Diseases ordinal scale (NIAID-OS) is an assessment of clinical status. The scale is as follows: 1) Not hospitalized, no limitations on activities; 2) Not hospitalized, limitation on activities and/or requiring home oxygen; 3) Hospitalized, not requiring supplemental oxygen - no longer requires ongoing medical care; 4) Hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 5) Hospitalized, requiring supplemental oxygen; 6) Hospitalized, on non-invasive ventilation or high-flow oxygen devices; 7) Hospitalized, on invasive mechanical ventilation or ECMO; 8) Death. A higher score is representative of worse clinical outcome with a score of 8 being the highest and representing death.
