Interventions
Registration Number
NCT00475215
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The purpose of the trial is to research the safety and to show faster recovery after administration of 2.0 mg/kg or 4.0 mg/kg sugammadex (Org 25969, MK-8616) given as a reversal agent for 0.6 mg/kg (0.15 mg/kg maintenance dose) rocuronium (Zemuron®) in participants diagnosed with or having a history of pulmonary disease. All drug administration will be via the intravenous (IV) route.

Primary Outcome Measures
NameTimeMethod
Time From Start of Sugammadex Administration to Recovery of T4/T1 Ratio to 0.9 in Participants With or Having a Past History of Pulmonary DiseaseUp to 90 minutes

The mean time from the start of sugammadex administration to recovery of the T4/T1 ratio to 0.9 was determined. Less time indicates faster recovery from neuromuscular blockade. The ratio of T4 (fourth twitch; amplitude of fourth response to train of four \[TOF\] stimulation is expressed as percent of control T4) over T1 (first twitch; amplitude of first response to TOF stimulation is expressed as percent of control T1) ranges from 0 (complete loss of T4 twitch response) to 1.0 (complete recovery of T4 twitch response). For TOF stimulation, 4 consecutive square wave supra-maximal stimuli of 0.2 msec duration were delivered at 2 Hz every 15 seconds. Neuromuscular monitoring was performed with the TOF-Watch® SX.

Percentage of Participants Experiencing ≥1 Adverse Event(s) (AE)Up to 7 days

The percentage of participants experiencing ≥1 AE(s) was determined for each arm. An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Percentage of Participants Discontinuing Study Treatment Due to an Adverse Event (AE)Up to 7 days

The percentage of participants discontinuing from study treatment due to an AE was determined for each arm. An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Secondary Outcome Measures
NameTimeMethod
Five-Second Head Lift Assessment 1: Prior to Transfer to the Recovery Room Following ExtubationUp to 6 hours (prior to transfer to the recovery room after extubation)

The ability of each cooperative (based on clinician determination) participant to perform a 5-second head lift was determined by the clinician. Participants were rated as either able or not able to complete the head lift task.

Time From Start of Sugammadex Administration to Recovery of T4/T1 Ratio to 0.7 in Participants With or Having a Past History of Pulmonary DiseaseUp to 90 minutes

The mean time from the start of sugammadex administration to recovery of the T4/T1 ratio to 0.7 was determined. Less time indicates faster recovery from neuromuscular blockade. The ratio of T4 (fourth twitch; amplitude of fourth response to train of four \[TOF\] stimulation is expressed as percent of control T4) over T1 (first twitch; amplitude of first response to TOF stimulation is expressed as percent of control T1) ranges from 0 (complete loss of T4 twitch response) to 1.0 (complete recovery of T4 twitch response). For TOF stimulation, 4 consecutive square wave supra-maximal stimuli of 0.2 msec duration were delivered at 2 Hz every 15 seconds. Neuromuscular monitoring was performed with the TOF-Watch® SX.

Time From Start of Sugammadex Administration to Recovery of T4/T1 Ratio to 0.8 in Participants With or Having a Past History of Pulmonary DiseaseUp to 90 minutes

The mean time from the start of sugammadex administration to recovery of the T4/T1 ratio to 0.8 was determined. Less time indicates faster recovery from neuromuscular blockade. The ratio of T4 (fourth twitch; amplitude of fourth response to train of four \[TOF\] stimulation is expressed as percent of control T4) over T1 (first twitch; amplitude of first response to TOF stimulation is expressed as percent of control T1) ranges from 0 (complete loss of T4 twitch response) to 1.0 (complete recovery of T4 twitch response). For TOF stimulation, 4 consecutive square wave supra-maximal stimuli of 0.2 msec duration were delivered at 2 Hz every 15 seconds. Neuromuscular monitoring was performed with the TOF-Watch® SX.

Level of Consciousness Assessment 2: Prior to Discharge From the Recovery RoomUp to 6 hours (prior to discharge from the recovery room)

The level of consciousness prior to discharge from the recovery room was determined by the clinician for each participant. Each participants was assigned 1 of 3 potential levels of consciousness: 1) awake and oriented; 2) arousable with minimal stimulation; or 3) responsive only to tactile stimulation.

Level of Consciousness Assessment 1: Prior to Transfer to the Recovery Room Following ExtubationUp to 6 hours (prior to transfer to the recovery room after extubation)

The level of consciousness prior to transfer to the recovery room was determined by the clinician for each participant. Each participants was assigned 1 of 3 potential levels of consciousness: 1) awake and oriented; 2) arousable with minimal stimulation; or 3) responsive only to tactile stimulation.

General Muscle Weakness Assessment 2: Prior to Discharge From the Recovery RoomUp to 6 hours (prior to discharge from the recovery room)

Each cooperative (based on clinician determination) participant was assessed by a clinician to determine if there was muscle weakness. Participants were rated as having or not having muscle weakness by the clinician.

Five-Second Head Lift Assessment 2: Prior to Discharge From the Recovery RoomUp to 6 hours (prior to discharge from the recovery room)

The ability of each cooperative (based on clinician determination) participant to perform a 5-second head lift was determined by the clinician. Participants were rated as either able or not able to complete the head lift task.
