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 [1] | |||||||||||||||||||||||||||
End point description |
RSV LRTD symptoms (cough, short of breath, wheezing, coughing up phlegm [sputum]) as assessed by RiiQ symptom scale score at baseline was reported. RiiQ symptom scale was a 13-items questionnaire rated on 4-point scale. Each symptom and total score was ranged from 0-3 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. Intent-to-Treat infected (ITT-i) analysis set included subjects who were randomised and treated (at least 1 dose) and had RSV infection confirmed by central laboratory analysis. Subjects with confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection (positive test by central laboratory analysis) were excluded. Here, 'n' (number analysed) represent number of subjects evaluable for specified category. Here, ‘99999’ indicate that data was not collected as subjects was randomised to other treatment arm.

Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
As the study was terminated early, a low number of subjects were enrolled, hence some efficacy analyses were not performed per change in the planned analysis. Thereby, data were analysed for safety and selected efficacy parameters only. |
