Time From Start of Administration of MK-8616 to Recovery T4/T1 Ratio to 0.9 Primary · Up to 90 minutes

The mean time from the start of MK-8616 administration to recovery T4/T1 ratio of 0.9 was determined. Less time indicates faster recovery from NMB. 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

Percentage of Participants Experiencing ≥1 Adverse Events (AEs) Secondary · Up to 7 days following MK-8616 administration

The percentage of participants experiencing ≥1 AEs was determined. An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment.

Sponsor's own description

The primary objective of this study is to explore the dose-response relation of MK-8616 (Org 25969) given as a reversal agent of Zemuron® at 1 to 2 post tetanic counts (PTCs); both Zemuron® and MK-8616 are administered by intravenous (iv) infusion. Another goal of the study is to evaluate the safety of single doses of MK-8616 administered to participants of American Society of Anesthesiologists (ASA) Physical Status Class 1 (otherwise normal, healthy participant); Class 2 (participant with a mild systemic disease); or Class 3 (participant with a severe systemic disease that limits activity, but is not incapacitating).
