Brief summary:
The objective of this trial was to explore the dose-response relation of sugammadex (Org 25969; MK-8616) administered for the reversal of neuromuscular blockade (NMB) at 3 and 15 minutes following administration of 1.0 and 1.2 mg/kg of Esmeron® (rocuronium) in participants receiving surgery, classified as American Society of Anesthesiologists (ASA) class 1 (otherwise normal, healthy participant), class 2 (participant with mild systemic disease), or class 3 (participant with a severe systemic disease that limits activity, but is not incapacitating).

Detailed description:
In the United States, the highest dose recommended in the package insert of Zemuron® (i.e. the trade name for Esmeron® in the US) is 1.2 mg/kg whereas in Europe it is 1.0 mg/kg. For both doses, dose recommendations for reversal with sugammadex were to be found. Hence, the present trial was set up to explore the dose-response relation of sugammadex given as an NMB reversal agent at 3 and 15 minutes following administration of 1.0 and 1.2 mg/kg of Esmeron® in subjects of ASA 1 to 3. The sub-investigator who performed any subjective safety assessments after anesthesia was to be remained blinded.

Arms:
arm 1: Placebo (single intravenous (IV) bolus) administered 3 minutes (min) after the bolus intubation dose of 1 mg/kg Esmeron®. arm 2: Sugammadex (2 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 3: Sugammadex (4 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 4: Sugammadex (8 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 5: Sugammadex (12 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 6: Sugammadex (16 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 7: Placebo (single intravenous (IV) bolus) administered 15 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 8: Sugammadex (2 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 9: Sugammadex (4 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 10: Sugammadex (8 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 11: Sugammadex (12 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 12: Sugammadex (16 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1 mg/kg Esmeron®. arm 13: Placebo (single IV bolus) administered 3 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 14: Sugammadex (2 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 15: Sugammadex (4 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 16: Sugammadex (8 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 17: Sugammadex (12 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 18: Sugammadex (16 mg/kg; single IV bolus) administered 3 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 19: Placebo (single IV bolus) administered 15 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 20: Sugammadex (2 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 21: Sugammadex (4 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 22: Sugammadex (8 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 23: Sugammadex (12 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1.2 mg/kg Esmeron®. arm 24: Sugammadex (16 mg/kg; single IV bolus) administered 15 min after the bolus intubation dose of 1.2 mg/kg Esmeron®.

Interventions: intervention 1: Sugammadex intervention 2: Placebo intervention 3: Esmeron®
Intervention descriptions: intervention 1: Sugammadex administered as a fast IV bolus dose (within 30 seconds) at 3 or 15 minutes following administration of Esmeron®, dosed at 2, 4, 8, 12 or 16 mg/kg according to participant actual body weight. intervention 2: 0.9% NaCl administered as a fast IV bolus dose (within 30 seconds) at 3 or 15 minutes following administration of Esmeron®, intervention 3: Esmeron® administered at 1 or 1.2 mg/kg as a fast IV bolus (within 10 seconds), dosed according to participant actual body weight.
