About this study
Official title: A Phase 4 Randomized, Active-Comparator Controlled Clinical Trial to Study the Safety of Sugammadex (MK-8616) for the Reversal of Neuromuscular Blockade Induced by Either Rocuronium Bromide or Vecuronium Bromide in American Society of Anesthesiologists (ASA) Class 3 or 4 Subjects
The purpose of this trial is to evaluate the safety of sugammadex for the reversal of neuromuscular blockade (NMB) induced by neuromuscular blockade agents (NMBA) rocuronium or vecuronium in adult American Society of Anesthesiologists (ASA) Physical Status Class 3 and 4 participants. The primary objectives of the study are to characterize the incidence of treatment emergent sinus bradycardia, treatment emergent sinus tachycardia, or other treatment emergent cardiac arrhythmias after administration of sugammadex and to evaluate the general safety of sugammadex in a population of ASA Class 3 and 4 participants in a surgical setting.
- Conditions
- Reversal of Neuromuscular Blockade
- Being tested
- Sugammadex 2 mg/kg, Sugammadex 4 mg/kg, Sugammadex 16 mg/kg, Neostigmine + Glycopyrrolate, Rocuronium
- Keywords
- arrhythmia, bradycardia, neuromuscular blocking agents, surgery, tachycardia
- Medical subject headings
- Arrhythmias, Cardiac, Bradycardia, Tachycardia
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Sugammadex 2 mg/kgDrug
Also called MK-8616, Bridion
Following administration of NMBA (Rocuronium or Vecuronium) to achieve moderate NMB, participants received a single i.v. bolus of Sugammadex 2 mg/kg for reversal of moderate NMB. Moderate block is a level of NMB in which peripheral nerve stimulation elicits one to four muscle twitches.
Sugammadex 4 mg/kgDrug
Also called MK-8616, Bridion
Following administration of NMBA (Rocuronium or Vecuronium) to achieve deep NMB, participants received a single i.v. bolus of Sugammadex 4 mg/kg for reversal of deep NMB. Deep block is a level of NMB in which peripheral nerve stimulation elicits no muscle twitches and high-frequency muscle stimulation elicits minimal levels of muscle contraction.
Sugammadex 16 mg/kgDrug
Also called MK-8616, Bridion
Following administration of NMBA (Rocuronium) to achieve deep NMB, participants received a single i.v. bolus of Sugammadex 16 mg/kg for reversal of deep NMB. Deep block is a level of NMB in which peripheral nerve stimulation elicits no muscle twitches and high-frequency muscle stimulation elicits minimal levels of muscle contraction.
Neostigmine + GlycopyrrolateDrug
Following administration of NMBA (Rocuronium or Vecuronium) to achieve moderate NMB, participants received a single i.v. bolus of Neostigmine (50 μg/kg; 5 mg maximum) and Glycopyrrolate (10 μg/kg; 1 mg maximum) for reversal of moderate NMB. Moderate block is a level of NMB in which peripheral nerve stimulation elicits one to four muscle twitches.
RocuroniumDrug
To achieve NMB, participants received steroidal NMBA Rocuronium Bromide administered via IV infusion and dosed according to participant body weight. NMBAs were concomitant medications used per label and at Investigator's discretion as an adjunct to general anesthesia.
VecuroniumDrug
To achieve NMB, participants received steroidal NMBA Vecuronium Bromide administered via IV infusion and dosed according to participant body weight. NMBAs were concomitant medications used per label and at Investigator's discretion as an adjunct to general anesthesia.
| Study group | Role | What they receive |
|---|---|---|
| Sugammadex 2 mg/kg | Experimental | Sugammadex 2 mg/kg administered as a single intravenous (IV) dose Receives: Drug: Sugammadex 2 mg/kg; Drug: Rocuronium; Drug: Vecuronium |
| Sugammadex 4 mg/kg | Experimental | Sugammadex 4 mg/kg administered as a single IV dose Receives: Drug: Sugammadex 4 mg/kg; Drug: Rocuronium; Drug: Vecuronium |
| Sugammadex 16 mg/kg | Experimental | Sugammadex 16 mg/kg administered as a single IV dose Receives: Drug: Sugammadex 16 mg/kg; Drug: Rocuronium |
| Neostigmine + Glycopyrrolate | Active comparator | Neostigmine 50 μg/kg (up to 5 mg maximum dose) plus glycopyrrolate 10 μg/kg (up to 1 mg maximum dose) administered as a single IV dose Receives: Drug: Neostigmine + Glycopyrrolate; Drug: Rocuronium; Drug: Vecuronium |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Treatment-Emergent Sinus Bradycardia Events
The percentage of participants experiencing treatment-emergent sinus bradycardia events was identified with continuous electrocardiogram (ECG) monitoring. Treatment-emergent sinus bradycardia were defined as a heart rate <60 bpm that has also decreased more than 20% compared to participant baseline heart rate value, sustained for at least 1 minute after administration of study intervention. Treatment-emergent sinus bradycardia events may or may not have been considered an adverse event (AE), as determined by investigator judgment.
Measured: Up to approximately 35 minutes post-administration
Percentage of Participants With Treatment-Emergent Sinus Tachycardia Events
The percentage of participants experiencing treatment-emergent sinus tachycardia events was identified with continuous ECG monitoring. Treatment-emergent sinus tachycardia is defined as a heart rate ≥100 bpm that has also increased more than 20% compared to participant baseline heart rate value, sustained for at least 1 minute after administration of study intervention. Treatment-emergent sinus tachycardia events may or may not have been considered an AE, as determined by investigator judgment.
Measured: Up to approximately 35 minutes post-administration
Percentage of Participants With Other Treatment-Emergent Cardiac Arrhythmia Events
The percentage of participants experiencing other treatment-emergent cardiac arrhythmia events was identified with continuous ECG monitoring. Other treatment-emergent cardiac arrhythmias were defined as new or worsening arrhythmias (e.g., atrial fibrillation, atrial tachycardia, ventricular fibrillation, or ventricular tachyarrhythmia), sustained for at least 1 minute after administration of study intervention. Worsening arrhythmia events may or may not have been considered an AE, as determined by investigator judgment.
Measured: Up to approximately 35 minutes post-administration
Percentage of Participants Experiencing an Adverse Event (AE) Up To 7 Days After Administration of Study Intervention
As per the protocol primary analysis, the percentage of participants experiencing an AE up to 7 days after administration of study intervention was reported. An AE was defined as any untoward medical occurrence in a participant which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE.
Measured: Up to 7 days
Percentage of Participants Experiencing a Serious Adverse Event (SAE) Up To 7 Days After Administration of Study Intervention
As per the protocol primary analysis, the percentage of participants experiencing an SAE up to 7 days after administration of study intervention was reported. An SAE was an adverse event that: resulted in death; was life threatening; resulted in persistent or significant disability or incapacity; resulted in or prolonged an existing inpatient hospitalization; was a congenital anomaly or birth defect; was an other important medical event, was a cancer; or was associated with an overdose.
Measured: Up to 7 days
Percentage of Participants Experiencing an Event of Clinical Interest (ECI) Up To 7 Days After Administration of Study Intervention
As per the protocol primary analysis, the percentage of participants experiencing an ECI up to 7 days after administration of study intervention was reported. ECIs were a discrete set of both AEs and SAEs, specifically designated as such for the trial. For the purposes of this investigation, ECIs included 1) drug-induced liver injury; 2) clinically-relevant arrhythmias, inclusive of bradycardia and tachycardia defined as events necessitating intervention, as determined by investigator judgment; and 3) instances of hypersensitivity and/or anaphylaxis adjudicated by an external expert Adjudication Committee. A participant could have experienced more than one type of ECI.
Measured: Up to 7 days
