    Serum trough concentrations of palivizumab were assessed at Screening, at Day 31 (30 days after the 1st dose) and Day 121 (30 days after the 4th dose).


Secondary Outcome Measures:
  • Percentage of Participants Requiring Hospitalization For Respiratory Syncytial Virus (RSV) Infection [ Time Frame: From the first administration of palivizumab to 30 days after the last administration of palivizumab. Mean (SD) duration of treatment was 183 (37.29) days. ] [ Designated as safety issue: No ]
  • Percentage of Participants Who Required Treatment for Respiratory Syncytial Virus (RSV) Infection [ Time Frame: From the first administration of palivizumab to 30 days after the last administration of palivizumab. Mean (SD) duration of treatment was 183 (37.29) days. ] [ Designated as safety issue: No ]
    Percentage of participants who required any of the investigated treatments (admission in the intensive care unit [ICU], oxygen supplementation, mechanical ventilation, extracorporeal membrane oxygenation, continuous positive airway pressure and other mechanical respiratory support) for disease caused by RSV infection after the initial dose to 30 days after the last dose of the study drug.

  • Duration of Hospitalization Caused by Respiratory Syncytial Virus (RSV) Infection [ Time Frame: From the first administration of palivizumab to 30 days after the last administration of palivizumab. Mean (SD) duration of treatment was 183 (37.29) days. ] [ Designated as safety issue: No ]
    Number of days of hospitalization caused by RSV infection.

  • Duration of Required Treatment for Respiratory Syncytial Virus (RSV) Infection [ Time Frame: From the first administration of palivizumab to 30 days after the last administration of palivizumab. Mean (SD) duration of treatment was 183 (37.29) days. ] [ Designated as safety issue: No ]
    Duration (days) of requirement for any of the investigated treatments (admission in the intensive care unit [ICU], oxygen supplementation, mechanical ventilation, extracorporeal membrane oxygenation, continuous positive airway pressure and other mechanical respiratory support) for disease caused by RSV infection after the initial dose to 30 days after the last dose of the study drug.

  • Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), and Discontinuations Due to AEs [ Time Frame: From the first administration of palivizumab to 100 days after the last administration of palivizumab. Mean (SD) duration of treatment was 183 (37.29) days. ] [ Designated as safety issue: Yes ]
    An adverse event (AE) is defined as any untoward medical occurrence in a participant, which does not necessarily have a causal relationship with treatment. If an adverse event meets any of the following criteria, it is considered a serious adverse event (SAE): results in death or is life-threatening, results in admission or prolongation of hospitalization, results in congenital anomaly or persistent or significant disability/incapacity, or is an important medical event requiring medical or surgical intervention to prevent serious outcome. AEs were categorized by severity (mild, moderate, severe) and relationship to treatment (probably, possibly, probably not, not related). Please see Adverse Events section below for more details.
