Outcome Measures

Primary Outcomes (4)

  • Serum Concentrations of Nirsevimab

    Serum samples were collected at indicated timepoints to determine the serum concentration of nirsevimab.

    Pre-dose on Day 1 and on Days 2, 4, 6, 8, 15, 31, 91, 151 post-dose.

  • Maximum Observed Serum Concentration (Cmax) for Nirsevimab

    Cmax for nirsevimab was directly calculated from the individual concentration-time curve.

    Pre-dose on Day 1 and on Days 2, 4, 6, 8, 15, 31, 91, 151 post-dose

  • Time to Reach Maximum Observed Serum Concentration (Tmax) for Nirsevimab

    Tmax for nirsevimab was directly calculated from the individual concentration-time curve.

    Pre-dose on Day 1 and on Days 2, 4, 6, 8, 15, 31, 91, 151 post-dose

  • Area Under the Serum Concentration-Time Curve From Time 0 to 150 Days (AUC0-150) for Nirsevimab

    Area Under the Serum Concentration-Time Curve From Time 0 to 150 Days (AUC0-150) for Nirsevimab was calculated by linear up/log down trapezoidal summation.

    Pre-dose on Day 1 and on Days 2, 4, 6, 8, 15, 31, 91, 151 post-dose

Secondary Outcomes (1)

  • Number of Participants With Positive Anti-Drug Antibody (ADA) of Nirsevimab
