Clinical Trial Summary

The current trial was designed to demonstrate faster recovery in participants undergoing elective surgeries requiring profound neuromuscular blockade induced by rocuronium to a fourth twitch/first twitch (T4/T1) ratio of 0.9, after reversal of a target depth of neuromuscular blockade (NMB) of 1-2 Post Tetanic Count (PTC) by 4.0 mg.kg-1 Sugammadex compared to Placebo, to evaluate the safety of 4.0 mg.kg-1 Sugammadex and to evaluate the Operating Room (OR) and Post Anesthetic Care Unit (PACU) length of stay for these participants.

Study Design

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Treatment

Related Conditions & MeSH terms

• Anesthesia
• Neuromuscular Blockade

Intervention

Drug:
• Sugammadex
At a target depth of NMB of 1-2 PTC after the last dose of rocuronium, a bolus dose of 4.0 mg.kg-1 sugammadex (volume based on the actual body weight of the participant) will be administered, within 10 seconds into a fast running venous infusion.
• 0.9% sodium chloride (NaCl)
At 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	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.	From Start of IMP Administration to Recovery of the T4/T1 Ratio to 0.9 (estimated from ~2 minutes up to ~90 minutes)	No
Secondary	Time From Start of Administration of IMP to Recovery of the T4/T1 Ratio to 0.7	Neuromuscular functioning was monitored by applying repetitive 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 NMB, with a higher ratio indicating a greater recovery from NMB.	From Start of IMP Administration to Recovery of the T4/T1 Ratio to 0.7 (estimated from ~1 minute up to ~70 minutes)	No
Secondary	Time From Start of Administration of IMP to Recovery of the T4/T1 Ratio to 0.8	Neuromuscular functioning was monitored by applying repetitive 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 NMB, with a higher ratio indicating a greater recovery from NMB.	From Start of IMP Administration to Recovery of the T4/T1 Ratio to 0.8 (estimated from ~2 minutes up to ~80 minutes)	No
