The primary objective of this study is to evaluate the effects of presatovir on respiratory syncytial virus (RSV) viral load in RSV-positive adults who have been hospitalized with acute respiratory infectious symptoms.
Participants will receive 1 dose of presatovir on Day 1 and followed for 27 days postdose. Nasal swabs will be collected at each study visit (excluding Day 28) and assayed for change in viral load as the primary endpoint.

- Time-Weighted Average Change in Respiratory Syncytial Viral (RSV) Load From Baseline to Day 5 [ Time Frame: Baseline to Day 5 ]The time-weighted average change, often referred to as the DAVG, provides the average viral burden change from baseline. The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factor.
- Time-weighted Average Change in the Flu-PRO Score From Baseline to Day 5 [ Time Frame: Baseline to Day 5 ]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). The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factor.
- Number of Hospitalization-Free Days Following Presatovir Administration [ Time Frame: Up to Day 28 ]
- Rate of Unplanned Medical Encounters [ Time Frame: Up to Day 28 ]The adjusted rate of unplanned medical encounters (clinic visits, emergency room visits, urgent care visits, and rehospitalizations) related to a respiratory illness after initial hospital discharge through Day 28 will be assessed. Event rate was calculated as the total number of unplanned medical encounters divided by the total number of participants. The mean values presented were adjusted for stratification factor.
