PRIMARY outcome

Timeframe: Up to 7 days

Population: Participants in the Full Analysis Set (participants who received at least 1 full dose of study drug and had an RSV viral load ≥ lower limit of quantification (LLOQ) of the real-time quantitative polymerase chain reaction (RT-qPCR) assay in the Day 1 nasal sample, as determined by RT-qPCR at the central lab) with available data were analyzed .

Timeframe: Up to 7 days

Population: Participants in the Full Analysis Set with available data were analyzed.

The Flu-PRO is a patient-reported outcome questionnaire utilized as a standardized method for evaluating symptoms of influenza. Flu-PRO Score was calculated as the mean of 38 individual scores. Individual scores ranged from 0 (no symptoms) to 4 (worst symptoms) for the 5-point severity scale and 0 (never) to 4 or more times (always) for the 5-point frequency scale. The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factor.
