Brief Summary:
The primary objective of this study was to compare the safety and efficacy of motavizumab to palivizumab when administered monthly by intramuscular (IM) injection for the reduction of the incidence of RSV hospitalization among children at high risk for serious RSV disease. A secondary objective was to compare the incidence of medically-attended lower respiratory infections (LRIs) between treatment groups.

Condition or disease Intervention/treatment Phase
Respiratory Syncytial Virus Infections Biological: motavizumab (MEDI-524) Biological: palivizumab Phase 3

Detailed Description:
A randomized, double-blind, palivizumab-controlled, multi-center, multi-national trial conducted during 2 Northern Hemisphere RSV seasons with an intervening season in the Southern Hemisphere. Each child only participated during a single RSV season. Approximately 6,600 children at risk for serious RSV disease were to be randomized in a 1:1 ratio to receive either 15 mg/kg of palivizumab or motavizumab by IM injection every 30 days for a total of 5 doses.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of RSV Hospitalization (Includes Deaths by RSV) [ Time Frame: Days 0 - 150 ]
    RSV hospitalization was defined as 1) a respiratory hospitalization with a positive RSV test (primary), 2) a new onset of lower respiratory symptoms in an already hospitalized child, with an objective measure of worsening respiratory status and positive RSV test (nosocomial), or 3) death demonstrated to have been caused by RSV (by autopsy or clinical history and virologic evidence).

  2. Number of Participants Reporting Any Adverse Events (AEs) [ Time Frame: Days 0 - 150 ]
    Number of participants reporting one or more AEs

  3. Number of Participants Reporting Any Related AEs [ Time Frame: Days 0 - 150 ]
    Number of participants reporting one or more AEs considered related to study drug by the investigator

  4. Number of Participants Reporting Any Serious Adverse Events (SAEs) [ Time Frame: Days 0 - 150 ]
    Number of participants reporting one or more SAEs

  5. Number of Participants Reporting Any Related SAEs [ Time Frame: Days 0 - 150 ]
    Number of participants reporting one or more SAEs considered related to study drug by the investigator

  6. Number of Participants Reporting AEs by Highest Severity Grade [ Time Frame: Days 0 - 150 ]
    Adverse events events were graded by severity; Level 1, 2, 3, or 4

  7. Number of Participants Who Discontinued Study Drug Due to AEs [ Time Frame: Days 0 - 150 ]
  8. Number of Participants Who Died [ Time Frame: Days 0 - 150 ]
  9. Number of Participants Reporting Changes in Vital Signs From Baseline [ Time Frame: Days 0 - 150 ]
    Vital signs that were in a higher toxicity grade than observed at baseline were to be recorded as AEs


Secondary Outcome Measures :
  1. The Incidence of Outpatient Medically-attended Lower Respiratory Illness (LRI) [ Time Frame: Day 0 - 150 ]
    LRI was defined as an event of bronchiolitis or pneumonia or the occurance of a lower tract infectious illness as determined by the PI based on medical history, signs, and symptoms.

  2. The Incidence of RSV-specific Medically-attended Outpatient Lower Respiratory Illnesses (LRIs) Between Treatment Groups [ Time Frame: Days 0 - 150 ]
    The RSV-specific LRI was defined as an outpatient medically-attended LRI associated with a positive RSV test and was not inclusive of events that required hospitalization.

  3. The Incidence of Medically-attended Otitis Media (OM) Infections [ Time Frame: Days 0 - 150 ]
    Otitis media (OM) was to be recorded as the diagnosis if the following terms were used by the medical care provider: acute OM, acute tympanic membrane (TM) perforation, bulging TM, red TM with fever, OM with effusion, or middle ear effusion. A new episode was defined as a physician-diagnosed OM in either ear after a normal middle ear exam of the ear in question or an episode of acute OM greater than or equal to 21 days after resolution of the previous episode. A diagnosis of persistent middle ear effusion was not to be recorded as a new OM event.

  4. The Frequency of Prescribed Antibiotics for Medically-attended LRI [ Time Frame: Days 0 - 150 ]
    The average number of presciptions per event per subject was summarized for each treatment group.

  5. The Frequency of Prescribed Antibiotics for Medically-attended OM Infections [ Time Frame: Days 0 - 150 ]
    The average number of presciptions per event per subject was summarized for each treatment group.

  6. The Number of Participants With Anti-motavizumab Antibodies [ Time Frame: Day 0 - 120 ]
    Detection of anti-motavizumab antibodies was defined as a titer with a dilution value equal to or greater than 1:10.

  7. The Serum Concentrations of Motavizumab at Day 0 [ Time Frame: Day 0 ]
    Mean serum concentrations of motavizumab at Day 0

  8. The Trough Serum Concentrations of Motavizumab at 30 Days Post Dose 1 [ Time Frame: 30 days post Dose 1 ]
    Mean serum concentrations of motavizumab at 30 days post Dose 1

  9. The Trough Serum Concentrations of Motavizumab at 30 Days Post Dose 2 [ Time Frame: 30 days post Dose 2 ]
    Mean serum concentrations of motavizumab at 30 days post Dose 2

  10. The Trough Serum Concentrations of Motavizumab at 30 Days Post Dose 3 [ Time Frame: 30 days post Dose 3 ]
    Mean serum concentrations of motavizumab at 30 days post Dose 3

  11. The Trough Serum Concentrations of Motavizumab at 30 Days Post Dose 4 [ Time Frame: 30 days post Dose 4 ]
    Mean serum concentrations of motavizumab at 30 days post Dose 4
