Title Part 1: Percentage of Participants Alive and Free of Respiratory Failure at Day 28
Hide Description Participants were considered alive and free of respiratory failure if they were in category 1, 2, 3, or 4 from the GlaxoSmithKline (GSK) modified version ordinal scale adapted from World Health Organization (WHO) scale 2020. The 8-point scale was as follows: 1) Non-hospitalized, no limitation of activity; 2) Non-hospitalized,limitation of activity; 3) Hospitalized, no oxygen therapy; 4) Hospitalized, low-flow oxygen by mask or nasal prongs; 5) Hospitalized, highflow oxygen (greater than or equal to [>=]15 liters per minute [L/min]), continuous positive airway pressure (CPAP), bilevel positive airway pressure (BIPAP), non-invasive ventilation; 6) Hospitalized, intubation and mechanical ventilation; 7) Hospitalized, mechanical ventilation plus additional organ support; 8) Death. Higher scale indicates higher intensity of respiratory failure. Percentage values are rounded off.

Hide Description Participants were alive and free of respiratory failure if they were in category 1, 2, 3 or 4 from the GlaxoSmithKline (GSK) modified version ordinal scale adapted from World Health Organization (WHO) scale 2020. The 8-point scale was as follows: 1) Non-hospitalized, no limitation of activity; 2) Non-hospitalized,limitation of activity; 3) Hospitalized, no oxygen therapy; 4) Hospitalized, low-flow oxygen by mask or nasal prongs; 5) Hospitalized, highflow oxygen (>=15L/min), continuous positive airway pressure (CPAP), bilevel positive airway pressure (BIPAP), non-invasive ventilation; 6) Hospitalized, intubation and mechanical ventilation; 7) Hospitalized, mechanical ventilation plus additional organ support; 8) Death. Higher scale indicates higher intensity of respiratory failure. Percentage values are rounded off.

Hide Description Time to first discharge to non-hospitalized residence was defined as the time (days) from dosing to when the participant was discharged to a non-hospitalized residence for the first time up to (and including) Day 60. Median and inter-quartile range (first quartile and third quartile) of time to first discharge to non-hospitalized residence is presented.

Title Part 1: Number of Participants With Serious Adverse Events (SAEs) and Common (>=5%) Non-serious Adverse Events (Non-SAEs)
Hide Description An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is defined as any untoward medical occurrence that, at any dose may result in death or is life-threatening or requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity or is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment or is associated with liver injury and impaired liver function.

All-cause mortality was reported for Enrolled population (all participants who entered the study). Sixteen participants from Enrolled Population (N=1156) did not receive study treatment, hence were not included in Safety Population (N=1140).
