Use of Sugammadex at the End of Case in Routine Anesthesia (MK-8616-023)
March 15, 2019 updated by: Merck Sharp & Dohme LLC
A Multicenter, Open Label, Phase IIIa Trial to Evaluate the Efficacy and Safety of Org 25969 When Used at the End of a Surgical Procedure to Reverse the Neuromuscular Block Induced by Rocuronium Following Routine Anesthesia
The primary purpose of the study is to determine the time-course of recovery to a T4/T1 ratio of 0.9 within 4 minutes after 4.0 mg.kg^-1 Sugammadex is administered at least 15 minutes after the last administration of rocuronium in a wide range of surgical procedures and anesthetic regimens (routine use).
Safety evaluation is part of the study.

Intervention / Treatment |
---|---|
Experimental: Sugammadex
Each participant received an intravenous single bolus dose of 0.6 mg/kg rocuronium.
If further neuromuscular block was required after endotracheal intubation, maintenance dose(s) of 0.15 mg/kg rocuronium was administered.
At least 15 minutes after the intubation dose or the last maintenance dose of rocuronium, an intravenous single bolus dose of 4.0 mg/kg MK-8616 was administered.

Other Names:

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time From Start of MK-8616 Administration to Recovery of the T4/T1 Ratio to 0.9
Time Frame: Up to approximately 30 minutes following administration of study treatment
|
Mean time from start of MK-8616 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).

Up to approximately 30 minutes following administration of study treatment

Measure Description |
Time Frame |
---|---|---|
Time From Start of MK-8616 Administration to Recovery of the T4/T1 Ratio to 0.7
Time Frame: Up to approximately 10 minutes following administration of study treatment
|
Mean time from start of MK-8616 administration to recovery of participant T4/T1 ratio to 0.7 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.

|
Time From Start of MK-8616 Administration to Recovery of the T4/T1 Ratio to 0.8
Time Frame: Up to approximately 15 minutes following administration of study treatment
|
Mean time from start of MK-8616 administration to recovery of participant T4/T1 ratio to 0.8 was assessed through the repeated application (every 15 seconds) of an electrical stimulation protocol.

Clinical Assessment of Recovery - Participant's Level of Consciousness
Time Frame: Up to 24 hours
|
The quality of recovery was assessed by asking the participant 40 questions from a validated Quality of Recovery Questionnaire (QoR-40).
Participants were assessed for level of consciousness (i.e., awake and oriented, arousable with minimal stimulation, responsive only to tactile stimulation), if applicable, by asking their name, if they are aware of where they are, and what day it is.
Assessment 1 occurred prior to transfer to the recovery room after extubation and Assessment 2 occurred prior to discharge from the recovery room.
|
Up to 24 hours
|
Clinical Assessments of Recovery - Participant Able to Perform 5-second Head Lift (5SHL)
Time Frame: Up to 24 hours
|
5-second head lift test was assessment of the ability of the participant to lift the head for 5 seconds and was performed by a blinded safety assessor.
Tests were repeated every 15 minutes until the participant could successfully perform the 5-second head-lift.
Assessment 1 occurred prior to transfer to the recovery room after extubation and Assessment 2 occurred prior to discharge from the recovery room.
|
Up to 24 hours
|
Clinical Assessments of Recovery - Check for General Muscle Weakness (GMW)
Time Frame: Up to 24 hours
|
General muscle weakness check was assessed by the investigator.
The assessment of general muscle weakness was based on a scale from 0-10, with 0 representing total paralysis, 1 signifying extreme impairment, 9 for close to no impairment, and 10 for normal muscle strength.
Scores of 3, 4, 5, etc. denoted increasing muscle strength in approximately 10% increments.
Scores of 9 and lower were denoted as GMW.
Assessment 1 occurred prior to transfer to the recovery room after extubation and assessment 2 occurred prior to discharge from the recovery room.

Up to 24 hours
