Anesthesia, General

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.

Interventions

DRUGSugammadex

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.

DRUGPlacebo

0.9% NaCl administered as a fast IV bolus dose (within 30 seconds) at 3 or 15 minutes following administration of Esmeron®,

Esmeron® administered at 1 or 1.2 mg/kg as a fast IV bolus (within 10 seconds), dosed according to participant actual body weight.

Primary

MeasureTime frameDescription
Mean Time From Start of Study Treatment Administration to Recovery of the T4/T1 Ratio to 0.9Up to 240 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).

Mean Time From Start of Study Treatment Administration to Recovery of the T4/T1 Ratio to 0.7Up to 180 minutes following administration of study treatmentMean time from start of study treatment 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. thumb twitch response) was assessed.

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).
Number of Participants Experiencing an Adverse EventUp to 7 days following administration of study treatmentThe 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.

Participant flow

Recruitment details

Of the N=174 randomized participants, N=173 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

N=2 participants (randomized to Arm O) received (rec'd) 8 mg/kg Sugammadex, 3 minutes (min) after 1.2 mg/kg Esmeron® and are counted as Started/Treated in Arm P. Further, N=1 participant (randomized to Arm Q) rec'd 12 mg/kg Sugammadex, 29 min after 1.2 mg/kg Esmeron® and is counted as Started/Treated in Arm W.

Outcome results

Primary

Mean Time From Start of Study Treatment Administration to Recovery of the T4/T1 Ratio to 0.9

Mean 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).

Time frame: Up to 240 minutes following administration of study treatment

Population: Includes all participants receiving study treatment, having ≥1 post-baseline observation without a major protocol violation. Additionally, N=1 participant was excluded from Arm M due to missing data and N=1 participant was excluded from Arm N due to unreliability of the neuromuscular data.

Mean Time From Start of Study Treatment Administration to Recovery of the T4/T1 Ratio to 0.7

Mean time from start of study treatment 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. 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 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 0.7 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).

Time frame: Up to 180 minutes following administration of study treatment

Population: Includes all participants receiving study treatment, having ≥1 post-baseline observation without a major protocol violation.

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 participants receiving study treatment. N=2 participants (originally randomized to Arm O), rec'd 8 mg/kg sugammadex, 3 min after 1.2 mg/kg Esmeron® (counted in Arm P). N=1 participant (originally randomized to Arm Q) rec'd 12 mg/kg sugammadex, 29min after 1.2 mg/kg Esmeron® (counted in Arm W).
