Outcome Measures
Primary Outcomes (7)
Respiratory Syncytial Virus (RSV) Lower Respiratory Tract Disease (LRTD) Symptoms as Assessed by Respiratory Infection Intensity and Impact Questionnaire (RiiQ) Symptom Scale Score at Baseline
RSV LRTD symptoms (cough, short of breath, wheezing, coughing up phlegm \[sputum\]) as assessed by the RiiQ symptom scale score at baseline were reported. The RiiQ symptom scale was a 13-items questionnaire rated on a 4-point scale. Each symptom was rated on a scale of 0 to 3 where 0=None, 1=Mild, 2=Moderate, and 3=Severe. Higher scores indicated greater severity. The LRTD symptom score was calculated as the mean of the LRTD symptom scores.
Baseline
Respiratory Syncytial Virus (RSV) Lower Respiratory Tract Disease (LRTD) Symptoms as Assessed by Respiratory Infection Intensity and Impact Questionnaire (RiiQ) Symptom Scale Score at Day 3
RSV LRTD symptoms (cough, short of breath, wheezing, coughing up phlegm \[sputum\]) as assessed by the RiiQ symptom scale score at Day 3 were reported. The RiiQ symptom scale was a 13-items questionnaire rated on a 4-point scale. Each symptom was rated on a scale of 0 to 3 where 0=None, 1=Mild, 2=Moderate, and 3=Severe. Higher scores indicated greater severity. The LRTD symptom score was calculated as the mean of the LRTD symptom scores. In this outcome measure, only those individual participants who had data were reported.
Day 3
Respiratory Syncytial Virus (RSV) Lower Respiratory Tract Disease (LRTD) Symptoms as Assessed by Respiratory Infection Intensity and Impact Questionnaire (RiiQ) Symptom Scale Score at Day 8
RSV LRTD symptoms (cough, short of breath, wheezing, coughing up phlegm \[sputum\]) as assessed by the RiiQ symptom scale score at Day 8 were reported. The RiiQ symptom scale was a 13-items questionnaire rated on a 4-point scale. Each symptom was rated on a scale of 0 to 3 where 0=None, 1=Mild, 2=Moderate, and 3=Severe. Higher scores indicated greater severity. The LRTD symptom score was calculated as the mean of the LRTD symptom scores. In this outcome measure, only those individual participants who had data were reported.

Higher scores indicated greater severity. The LRTD symptom score was calculated as the mean of the LRTD symptom scores. In this outcome measure, only those individual participants who had data were reported.
Day 14

Eligibility Criteria
You may qualify if:
- Presented to the healthcare facility with symptoms suggestive of a diagnosis of acute respiratory syncytial virus (RSV) infection
- Has at least 2 symptoms of lower respiratory tract disease (LRTD), one of which must be scored as at least 'moderate' if the symptoms did not pre-exist before RSV onset, or one of which is scored worse than usual if the symptoms pre-existed
- Tested positive for RSV infection using a molecular-based diagnostic assay (polymerase chain reaction \[PCR\] or other) on a bilateral nasal mid-turbinate swab sample
- Has at least one of the following high-risk conditions that predispose them to RSV-related disease progression: a. age greater than or equal to (\>=) 65 years, b. congestive heart failure (CHF), c. chronic obstructive pulmonary disease (COPD), d. asthma
- Randomized to study intervention treatment within 72 hours after onset of any of the RSV symptoms or worsening of pre-existing symptoms
- Not be hospitalized during screening (emergency room or hospital observation status for an anticipated duration of less than \[\<\] 24 hours are not considered as hospitalization)
You may not qualify if:
- Known allergies, hypersensitivity, or intolerance to rilematovir or to any of the excipients of rilematovir or placebo formulation
- Presence of clinically significant heart arrhythmias, uncontrolled, unstable atrial arrhythmia, or sustained ventricular arrhythmia
- Participant has known or suspected (from medical history or participant examination) chronic or acute hepatitis B or C infection
- Immunocompromised conditions
- Living in institutional care or assisted living facility and also receiving acute care management for any respiratory condition

Limitations and Caveats
As the study was terminated early, a low number of participants were enrolled, hence some efficacy analyses were not performed per change in the planned analysis. Thereby, data were analyzed for safety and selected efficacy parameters only.
