Brief summary

This study investigates the efficacy, safety, and pharmacokinetics of sugammadex (Org 25969; MK-8616) when administered for the reversal of neuromuscular blockade in male participants receiving surgery, classified as American Society of Anesthesiologists (ASA) class 1 (otherwise normal, healthy participant) to class 2 (participant with mild systemic disease). The primary objective of this study is to explore the dose-response relation of sugammadex given as a reversal agent at 3, 5, or 15 minutes following administration of 0.6 mg/kg Esmeron®.

Interventions

DRUGPlacebo

0.9% NaCl administered as a fast IV bolus dose (within 30 seconds).

DRUGSugammadex

Sugammadex administered as a fast IV bolus dose (within 30 seconds), dosed according to participant actual body weight.

Esmeron® administered at 0.6 mg/kg as a fast IV bolus (within 10 seconds), dosed according to participant actual body weight.

Inclusion criteria

* Participants of ASA class 1 to 2. * Participants scheduled for surgical procedures with an anticipated duration of anesthesia of at least 75 minutes, without further need for muscle relaxation other than for intubation.

Exclusion criteria

* Participants in whom a difficult intubation because of anatomical malformations is expected. * Participants known or suspected to have neuromuscular disorders and/or significant hepatic or renal dysfunction. * Participants known or suspected to have a (family) history of malignant hyperthermia. * Participants known or suspected to have an allergy to narcotics, muscle relaxants or other medication used during general anesthesia. * Participants receiving medication known to interfere with neuromuscular blocking agents such as anticonvulsants, aminoglycosides, and Mg\^2+. * Participants who have already participated in this trial. * Participants who have participated in another clinical trial, not pre-approved by NV Organon, within 30 days of entering into this trial.

MeasureTime frameDescription
Mean Time From Start of Study Treatment Administration to Recovery of the T4/T1 Ratio to 0.9Up to 70 minutes following administration of study treatmentMean time from start of study treatment administration to recovery of participant T4/T1 ratio to 0.9 was assessed through the repeated application (every 15 seconds) of an electrical stimulation protocol. Specifically, 4 electrical stimulations were applied to the ulnar nerve and the magnitude of the twitch response of the adductor pollicis muscle (i.e. thumb twitch response) was assessed. With T4 and T1 referring to the respective magnitude of the fourth and first thumb twitch during nerve stimulation, the T4/T1 ratio indicates the current degree of neuromuscular blockade (NMB) present in the participant as a decimal from 0 (loss of T4 twitch) to 1 (no NMB). Further, reduced recovery time of the T4/T1 ratio to 0.9 indicates faster recovery from NMB. Summary data, originally presented in the format of units minutes:seconds (mm:ss), was reformatted to be presented in the single unit of minutes (min).

An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational product, whether or not considered related to the investigational product.

Participant flow

Recruitment details

Of the N=99 randomized participants, N=98 received treatment. Treated participants are counted as Started in the arm that most accurately describes the treatment received. If no treatment was received (N=1 participant), participants are counted as Started in the arm to which they were randomized.

Pre-assignment details

One participant originally randomized to receive 2 mg/kg Sugammadex, given 3 minutes after Esmeron® (Arm C), incorrectly received placebo. As a result, this participant is counted as Started/Treated in the Arm A. Placebo; given 3 minutes after Esmeron® arm.

RR interval = 60/heart rate.

Number of Participants Experiencing an Adverse Event

The number of participants experiencing an adverse event (AE) was assessed. An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational product, whether or not considered related to the investigational product.

Time frame: Up to 7 days following administration of study treatment

Population: Includes all randomized participants receiving study treatment. One participant randomized to receive 2 mg/kg Sugammadex, given 3 minutes after Esmeron® (Arm C), incorrectly received placebo. This participant is counted in the Arm A. Placebo; given 3 minutes after Esmeron® arm.
