Study Endpoints

Primary Endpoints

Number of Participants With Urinary Retention
6 hours postop

Urinary retention is defined as the inability to void at six hours postoperatively, which will be recorded in the postoperative recovery area and the same definition for urinary retention will be applied to the comparative retrospective cohort

Incidence of Residual Neuromuscular Blockade (NMB) as Defined by a Train-of-Four (TOF) Ratio <0.9 at Post Anesthesia Care Unit (PACU) Entry
At PACU entry on Day 1

Neuromuscular functioning was monitored by applying four TOF electrical stimulations to the ulnar nerve and assessing twitch response at the adductor pollicis muscle. T1 and T4 refer to the magnitudes (height) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (expressed as a decimal of up to 1.0) indicates the extent of recovery from NMB, with a higher ratio indicating greater recovery from NMB. A T4/T1 Ratio of \<0.9 is indicative of residual NMB.

Number of Participants With One or More Adjudicated Events of Bleeding (Major or Non-major) With Onset Within 24 Hours After Study Drug Administration
Up to 24 hours post study drug administration

Post-treatment events of bleeding were evaluated by a medically-qualified, blinded member of the surgical team (Blinded Safety Assessor), in consultation with the surgeon, to determine if an event was a "suspected, unanticipated adverse event of bleeding" (SUAEB). A SUAEB is an event of bleeding outside the usual boundaries of expectations for a participant (e.g., in amount of blood lost, prolonged duration of bleeding, or other factors) considering the type of procedure as well as participant's specific surgical experience and underlying risk of bleeding. In addition, blinded review of clinical and laboratory databases was performed to identify any event potentially consistent with a SUAEB; these were reviewed by the Blinded Safety Assessor, who determined if any was a SUAEB. All SUAEBs were evaluated by a blinded external Adjudication Committee, which classified each as either: 1) a major bleeding event, 2) a non-major bleeding event, or 3) not an unanticipated event of bleeding.

Time From Start of Study Drug Administration to Recovery of the T4/T1 Ratio to 0.9
From Start of Study Drug Administration to Recovery of the T4/T1 Ratio to 0.9 (estimated from 2 minutes up to ~15 minutes)

Neuromuscular functioning was monitored by applying repetitive Train-Of-Four (TOF) electrical stimulations to the ulnar nerve every 15 seconds \& assessing twitch response at the adductor pollicis muscle. T1 \& T4 refer to the magnitudes (height) of the 1st \& 4th twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (expressed as a decimal of up to 1.0) indicates the extent of recovery from neuromuscular blockade. In this study, twitch responses were recorded until the T4/T1 Ratio reached \>= 0.9, the minimum acceptable ratio that indicated complete recovery.

Time From Start of Administration of Sugammadex to Recovery of the T4/T1 Ratio to 0.9
Start of administration of sugammadex to recovery from neuromuscular blockade

Neuromuscular functioning was monitored by applying repetitive train of four (TOF) electrical stimulations to the ulnar nerve every 15 seconds and assessing twitch response at the adductor pollicis muscle. Nerve stimulation continued until the ratio of the magnitude of the fourth twitch (T4) to first twitch (T1) reached at least 0.9. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade, with a value of 1.0 representing full recovery. Analysis of recovery in Chinese subjects was the primary objective; Caucasian subjects and between-group analyses were secondary.

Time From Start of Administration of Investigational Medicinal Product (IMP) to Recovery of the T4/T1 Ratio to 0.9.
start of administration of sugammadex/neostigmine to recovery from neuromuscular blockade

Neuromuscular functioning was monitored by applying repetitive train of four (TOF) electrical stimulations to the ulnar nerve every 15 seconds and assessing twitch response at the adductor pollicis muscle. Nerve stimulation was to continue until the ratio of the magnitude of the fourth twitch (T4) to first twitch (T1) reached \>= 0.9. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade, with a value of 1.0 representing full recovery. The primary analysis was the comparison between sugammadex \& neostigmine among Chinese subjects; other comparisons were secondary.

Time From Start of Administration of Investigational Medicinal Product (IMP, Sugammadex or Placebo) to Recovery of the Fourth Twitch/First Twitch (T4/T1) Ratio to 0.9
From Start of IMP Administration to Recovery of the T4/T1 Ratio to 0.9 (estimated from ~2 minutes up to ~90 minutes)

Neuromuscular functioning was monitored by applying repetitive Train-Of-Four (TOF) electrical stimulations to the ulnar nerve every 15 seconds \& assessing twitch response at the adductor pollicis muscle. T1 and T4 refer to the magnitudes (height) of the first and fourth twitches, respectively, after TOF nerve stimulation. The T4/T1 Ratio (a percentage that is expressed as a decimal of up to 1.0) indicates the extent of recovery from neuromuscular blockade (NMB), with a higher ratio indicating a greater recovery from NMB. In this study, twitch responses were recorded until the T4/T1 Ratio reached \>=0.9, the minimum acceptable ratio that indicated complete recovery from NMB. A shorter time to recovery of the T4/T1 Ratio \>=0.9 indicates a faster recovery from NMB.

Time to Recovery of the T4/T1 Ratio to 0.9.
start of administration of sugammadex to recovery from neuromuscular blockade

Neuromuscular functioning was monitored by applying repetitive train of four (TOF) electrical stimulations to the ulnar nerve every 15 seconds and assessing twitch response at the adductor pollicis muscle. Nerve stimulation continued until the ratio of the magnitude of the fourth twitch (T4) to first twitch (T1) reached at least 0.9. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade, with a value of 1.0 representing full recovery.

Residual Neuromuscular Blockade Evidenced by T4/T1 Ratio at the Time of Tracheal Extubation
Up to the first 24 hours after tracheal extubation

Neuromuscular function was monitored by applying repetitive Train-Of-Four (TOF) electrical stimulations to the ulnar nerve every 15 seconds, and assessing twitch response at the adductor pollicis muscle with a TOF-Watch® SX. The magnitudes (heights) of the first and fourth twitches (T1 and T4) were used to calculate the T4/T1 ratio, where a higher T4/T1 ratio indicates a greater recovery from neuromuscular blockade, with a value of 1.0 indicating complete recovery. After anesthesia, when neuromuscular function was expected to be fully recovered, tracheal extubation was performed, at which time the T4/T1 ratio was measured, with any missing recovery times imputed.

after surgery
Time From Start of MK-8616 Administration to Recovery of the T4/T1 Ratio to 0.9
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).

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 Disease
Up 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.

Geometric Least Squares Mean Area Under the Plasma Drug Concentration-time Curve From Time Zero to Infinity (AUC0-∞) Following a Single IV Dose of Sugammadex
For participants with: normal renal function - up to 48 hours post-dose (Part 1 + Part 2); moderate renal insufficiency - up to Day 28 (Part 1) or Day 10 (Part 2); severe renal insufficiency - up to Day 35 (Part 1) or Day 14 (Part 2)

Plasma samples for determination of sugammadex pharmacokinetic parameters were obtained pre-dose and at specified post-dose time points. AUC0-∞ was calculated as the sum of the AUC to the last time point with a detectable plasma concentration (AUC0-last, determined by trapezoidal method) and the extrapolated area given by Cest,last/λz, where Cest,last is the estimated concentration corresponding to the time of the last measurable concentration and λz is the apparent first-order terminal elimination rate constant. For each subject, λz was calculated by regression of the terminal log-linear portion of the plasma concentration-time profile. The reported least squares mean is the geometric least squares mean, which is the back-transformed least squares mean from the analysis of variance (ANOVA) linear fixed-effect model performed on natural log-transformed values of AUC0-∞. This calculation also provides the associated 95% confidence interval.

Interventions

NameTypeDescription
SugammadexDRUGThe dosing for Sugammadex is 4mg/kg for a deep reversal and a 2mg/kg for a standard reversal, which will be more common for this study. Sugammadex comes in 200mg/2mL and 500mg/5mL vials. Because of the variability in weight of the patients and the type of reversal needed (deep vs standard), 140 5mL vials will be required.
NeostigmineDRUGneostigmine, per usual practice
GlycopyrrolateDRUGglycopyrrolate per usual practice
neostigmine and glycopyrrolate or atropineDRUGNeostigmine and glycopyrrolate or neostigmine and atropine administered intravenously per usual practice and per the product labels
Placebo to neostigmineDRUGNormal saline (NaCl 0.9%)
Placebo to sugammadexDRUGNormal saline (NaCl 0.9%)
0.9% sodium chloride (NaCl)DRUGAt a target depth of NMB of 1-2 PTC after the last dose of rocuronium, a bolus dose of placebo (0.9% NaCl, volume based on the actual body weight of the participant) will be administered, within 10 seconds into a fast running venous infusion.
RocuroniumDRUGParticipants received a single intubation bolus dose of 0.6 mg/kg rocuronium bromide, followed if necessary to maintain neuromuscular blockade by one or more single bolus dose(s) of 0.15 mg/kg rocuronium bromide.
