Summary

This trial will evaluate the efficacy, safety, and pharmacokinetics of sugammadex for the reversal of both moderate and deep neuromuscular blockade (NMB) induced by either rocuronium or vecuronium in pediatric participants. The primary efficacy hypothesis of this investigation is that sugammadex is superior to neostigmine in reversing moderate NMB in pediatric participants as measured by time to recovery to a train-of-four (TOF) ratio of ≥0.9.

Detailed description

This trial will be conducted in two parts: Part A and Part B. In Part A, pharmacokinetic (PK) sampling will be conducted to identify the pediatric dose providing sugammadex exposure similar to adults. For Part B participants, the efficacy of sugammadex (i.e. time to recovery of the TOF ratio) will be assessed. Further, safety analyses will be conducted in both Parts A and B. Following completion of Part A, an interim analysis (IA) of the PK and safety data will be performed. Once the appropriate doses are confirmed and safety data is assessed for the 2 doses of sugammadex, then Part B will commence.

Conditions

• Neuromuscular Blockade

Interventions

Type	Name	Description
DRUG	Sugammadex 2 mg/kg	For moderate NMB reversal, a single i.v. bolus of sugammadex (2 mg/kg) will be given after final dose of neuromuscular blocking agent (NMBA; rocuronium or vecuronium) and within 2 minutes of the reappearance of a second twitch (T2) in response to TOF stimulations.
DRUG	Sugammadex 4 mg/kg	For deep NMB reversal, a single i.v. bolus of sugammadex (4 mg/kg) will be given after final dose of NMBA (rocuronium or vecuronium) and within 2 minutes of detection of a target of 1 to 2 post-tetanic counts and no response to TOF stimulations (TOF=0).
DRUG	Neostigmine + Glycopyrrolate	For moderate NMB reversal, a single i.v. bolus containing both neostigmine (50 μg/kg; up to 5 mg maximum dose) as well as glycopyrrolate (10 μg/kg) will be given after final dose of NMBA (rocuronium or vecuronium) and within 2 minutes of the reappearance of a second twitch (T2) in response to TOF stimulations.
DRUG	Neostigmine + Atropine	For moderate NMB reversal, a single i.v. bolus containing both neostigmine (50 μg/kg; up to 5 mg maximum dose) as well as atropine (20 μg/kg) will be given after final dose of NMBA (rocuronium or vecuronium) and within 2 minutes of the reappearance of a second twitch (T2) in response to TOF stimulations.
