Time to Improvement in Clinical Status of Participants (Using 7-point Ordinal Scale Score) by at Least 2 Points [ Time Frame: Baseline to Day 29 ]
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.
