Merck Sharp & Dohme Corp.
  Purpose
The primary purpose of this study is to determine the dose requirements of rocuronium bromide when administered as a bolus dose (a single, large dose) for intubation (insertion of a tube through the nose or mouth into the trachea to provide artificial ventilation) and when administered by either continuous infusion or bolus doses for maintenance of muscle relaxation in term neonates (birth to <28 days old), infants (28 days to <=3 months) and toddlers (>3 months to <=2 years), children (2 years to less than or equal to 11 years of age), and adolescents (>11 years to less than or equal to 17 years of age).

Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label, Randomized, Phase IIIB, Multicenter Trial to Evaluate the Pharmacodynamic Parameters of Intubation Bolus, and Bolus and Infusion Maintenance Doses of Zemuron® in Pediatric and Adolescent Subjects

Primary Outcome Measures:
  • Total Dose of Zemuron (Rocuronium) Administered [ Time Frame: during surgery ]
    Total dose from administration of intubating dose to reappearance of T3 (the third twitch of a Train of Four [TOF] stimulation) after the last maintenance bolus dose or discontinuation of Zemuron (rocuronium) infusion (Per protocol [PP] data set)


Secondary Outcome Measures:
  • Duration of Recovery of T4/T1 Ratio (TOF Fourth Twitch to First Twitch) 70% [ Time Frame: after surgery, from the reappearance of T3 after Zemuron(R) (rocuronium) infusion/last bolus dose of Zemuron(R) (rocuronium) ]
    The time it takes for the the T4 to T1 ratio to reach 70%. The T4/T1 ratio is indicative of recovery. At complete recovery, the T4/T1 ratio is 1.0 (100%).

  • Duration of Recovery of T4/T1 (TOF Fourth Twitch to First Twitch) Ratio 80% [ Time Frame: after surgery, from the reappearance of T3 after Zemuron(R) (rocuronium) infusion/last bolus dose of Zemuron(R) (rocuronium) ]
    The time it takes for the the T4 to T1 ratio to reach 80%. The T4/T1 ratio is indicative of recovery. At complete recovery, the T4/T1 ratio is 1.0 (100%).

  • Duration of Recovery of T4/T1 (TOF Fourth Twitch to First Twitch) Ratio 90% [ Time Frame: after surgery, from the reappearance of T3 after Zemuron(R) (rocuronium) infusion/last bolus dose of Zemuron(R) (rocuronium) ]
    The time it takes for the the T4 to T1 ratio to reach 90%. The T4/T1 ratio is indicative of recovery. At complete recovery, the T4/T1 ratio is 1.0 (100%).
