About this study
Official title: A Multi-center, Randomized, Parallel-group, Active-controlled, Safety-assessor Blinded Trial, Comparing the Efficacy and Safety of 2.0 mg.Kg-1 Sugammadex With 50 μg.Kg-1 Neostigmine Administered at Reappearance of T2 After Rocuronium in Chinese and European ASA I-III Subjects Undergoing Elective Surgery Under Propofol Anesthesia
The present trial was set up to evaluate the efficacy and safety of 2.0 mg.kg-1 sugammadex compared to neostigmine administered at reappearance of T2 in Chinese and Caucasian subjects for registration purposes in China.
- Conditions
- Anesthesia, General, Neuromuscular Blockade
- Being tested
- Sugammadex, neostigmine
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SugammadexDrug
Also called Org 25969, Bridion®
After induction of anesthesia an intubation dose of 0.6 mg/kg rocuronium was administered. Maintenance doses of 0.1-0.2 mg/kg rocuronium intravenous (IV) could be administered if necessary. At reappearance of T2 after the last administration of rocuronium, an IV single bolus dose of 2.0 mg/kg sugammadex was administered.
neostigmineDrug
Also called Neostigmine with atropine
After induction of anesthesia an intubation dose of 0.6 mg/kg rocuronium was administered. Maintenance doses of 0.1-0.2 mg/kg rocuronium IV could be administered if necessary. At reappearance of T2 after the last administration of rocuronium, an IV single bolus dose of 50 µg/kg neostigmine (combined with 10-20 μg.kg-1 atropine, in a ratio ranging from 2.5:1 to 5:1) was administered.
| Study group | Role | What they receive |
|---|---|---|
| Sugammadex in Caucasian Subjects | Experimental | At reappearance of T2 after the last dose of rocuronium, 2.0 mg.kg-1 sugammadex was administered. Receives: Drug: Sugammadex |
| Neostigmine in Caucasian Subjects | Active comparator | At reappearance of T2 after the last dose of rocuronium, 50 μg.kg-1 neostigmine (combined with 10-20 μg.kg-1 atropine, in a ratio ranging from 2.5:1 to 5:1) was administered. Receives: Drug: neostigmine |
| Sugammadex in Chinese Subjects | Experimental | At reappearance of T2 after the last dose of rocuronium, 2.0 mg.kg-1 sugammadex was administered. Receives: Drug: Sugammadex |
| Neostigmine in Chinese Subjects | Active comparator | At reappearance of T2 after the last dose of rocuronium, 50 μg.kg-1 neostigmine (combined with 10-20 μg.kg-1 atropine, in a ratio ranging from 2.5:1 to 5:1) was administered. Receives: Drug: neostigmine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Time From Start of Administration of Investigational Medicinal Product (IMP) to Recovery of the 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 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.
Measured: start of administration of sugammadex/neostigmine to recovery from neuromuscular blockade
Secondary outcomes (1)
Time From Start of Administration of IMP to Recovery of the T4/T1 Ratio to 0.7 and 0.8.
Neuromuscular functioning was monitored by applying repetitive TOF electrical stimulations to the ulnar nerve every 15 seconds and assessing twitch response at the adductor pollicis muscle. The greater the T4/T1 ratio the greater the recovery from neuromuscular blockade.
Measured: start of administration of sugammadex/neostigmine to recovery from neuromuscular blockade

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Sugammadex and neostigmine in people with Anesthesia, General and Neuromuscular Blockade, run by Merck Sharp & Dohme LLC.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time From Start of Administration of Investigational Medicinal Product (IMP) to Recovery of the T4/T1 Ratio to 0.9. (time frame: start of administration of sugammadex/neostigmine to recovery from neuromuscular blockade). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00825812, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2015.
