- Part A: Percentage of Participants in Each Clinical Status Category as Assessed by a 7-Point Ordinal Scale on Day 14 [ Time Frame: Day 14 ]Clinical status was derived from death, hospital discharge, and the ordinal scale as follows: score of "1" was used for all days on or after the date of death; score of "7" was used for all days on or after discharged alive date; last assessment carried forward for any missing values.The scale is as follows: 1. Death; 2. Hospitalized, on invasive mechanical ventilation or ECMO; 3. Hospitalized, on non-invasive ventilation or high flow oxygen devices; 4. Hospitalized, requiring low flow supplemental oxygen; 5. Hospitalized, not requiring supplemental oxygen - requiring ongoing medical care (COVID-19 related or otherwise); 6. Hospitalized, not requiring supplemental oxygen - no longer required ongoing medical care (other than per protocol remdesivir administration); 7. Not hospitalized. The odds ratio represents the odds of improvement in the ordinal scale for the Remdesivir for 10 days group vs the Remdesivir for 5 days group.
- Part A: Percentage of Participants Who Experienced Treatment-Emergent Adverse Events (TEAEs) [ Time Frame: First dose date up to last dose date (maximum: 10 days) plus 30 days ]Treatment-emergent Adverse Events (TEAE) were defined as AEs with onset dates on or after the study treatment start date and no later than 30 days after the permanent discontinuation of the study treatment and/or the AEs that led to premature discontinuation of study treatment.
