Part 1: Percentage of Participants Alive and Free of Respiratory Failure at Day 28
At Day 28

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.
