Primary Outcomes

Description: 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.

Measure: Time-Weighted Average Change in Respiratory Syncytial Viral (RSV) Load From Baseline to Day 5

Time: Baseline to Day 5

---

Secondary Outcomes

Description: 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.

Measure: Time-weighted Average Change in the Flu-PRO Score From Baseline to Day 5

Time: Baseline to Day 5

---

Measure: Number of Hospitalization-Free Days Following Presatovir Administration

Time: Up to Day 28

---

Description: 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.

Measure: Rate of Unplanned Medical Encounters

Time: Up to Day 28

---

Primary Outcomes

Description: 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.

Measure: Time-Weighted Average Change in Nasal Respiratory Syncytial Virus (RSV ) Viral Load From Baseline (Day 1) to Day 9

Time: Baseline; Day 9

---

Description: A Lower Respiratory Tract Complication (LRTC) was defined as one of the below as determined by the adjudication committee: Primary RSV lower respiratory tract infection (LRTI) Secondary bacterial LRTI LRTI due to unusual pathogens Lower respiratory tract complication of unknown etiology

Measure: Percentage of Participants Who Developed a Lower Respiratory Tract Complication

Time: Up to Day 28

---

Secondary Outcomes

Description: Participants were considered to have an event if either condition is met: Participant develops a respiratory failure (of any cause) requiring mechanical ventilation (invasive or noninvasive) or; Participant dies prior to or on Day 28

Measure: Percentage of Participants Who Developed Respiratory Failure (of Any Cause) Requiring Mechanical Ventilation (Invasive or Noninvasive) or All-cause Mortality

Time: Up to Day 28

Measure: Time-weighted Average Change in Nasal Respiratory Syncytial Viral (RSV) Load From Baseline to Day 9

Time: Baseline to Day 9

---

Secondary Outcomes

Measure: Number of Supplemental O2-Free Days Through Day 28

Time: Up to Day 28

---

Measure: Percentage of Participants Developing Respiratory Failure Requiring Mechanical Ventilation Through Day 28

Time: Up to Day 28

---

Measure: Percentage of All-Cause Mortality Among Participants Through Day 28

Time: Up to Day 28

---

Primary Outcomes

Measure: Time-Weighted Average Change in Viral Load From Day 1/Baseline Through Day 7 in Participants in the Full Analysis Set

Time: Up to 7 days

---

Measure: Time-Weighted Average Change in Viral Load From Day 1/Baseline Through Day 7 in a Subset of Participants in the Full Analysis Set Whose Duration of RSV Symptoms Prior to the First Dose of Study Drug is ≤ Median

Time: Up to 7 days

---

Secondary Outcomes

Description: 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.

Measure: Time-Weighted Average Change in FLU-PRO Score From Day 1/Baseline Through Day 7

Time: Up to 7 days

---

Description: FEV1 is defined as forced expiratory volume in the first second.

Measure: Percent Change From Study Baseline in FEV1% Predicted Value

Time: Baseline; Day 28
