What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time From Start of Administration of Study Treatment (Sugammadex or Placebo) to Recovery 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 \& T4 refer to the magnitudes (heights) of the first \& 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 neuromuscular blockade (NMB). In this study, twitch responses were recorded until the T4/T1 Ratio reached ≥0.9, the minimum acceptable ratio that indicated recovery from NMB. A faster time to recovery of the T4/T1 Ratio to 0.9 indicates a faster recovery from NMB.

    Measured: From start of sugammadex or palcebo administration to recovery of T4/T1 ratio to 0.9 (ranging from ~0.5 minutes to ~30 minutes from sugammadex or placebo administration)

Secondary outcomes (2)
  1. Time From Start of Administration of Study Treatment (Sugammadex or Placebo) to Recovery 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 \& T4 refer to the magnitudes (heights) of the first \& 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. A faster time to recovery of the T4/T1 Ratio to 0.7 indicates a faster recovery from NMB.

    Measured: From start of sugammadex or placebo administration to recovery of T4/T1 ratio to 0.7 (ranging from ~0.4 minutes to ~20 minutes from sugammadex or placebo administration)

  2. Time From Start of Administration of Study Treatment (Sugammadex or Placebo) to Recovery 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 \& T4 refer to the magnitudes (heights) of the first \& 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. A faster time to recovery of the T4/T1 Ratio to 0.8 indicates a faster recovery from NMB.

    Measured: From start of sugammadex or placebo administration to recovery of T4/T1 ratio to 0.8 (ranging from ~0.5 minutes to ~25 minutes from sugammadex or placebo administration)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Sugammadex 0.5 mg/kg, Sugammadex 1 mg/kg and Sugammadex 2 mg/kg in people with Anesthesia, 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 4 inclusion and 9 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 28 Jan 2019. 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. Some participants in this study may receive a placebo. 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 28 Jan 2019). 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 Study Treatment (Sugammadex or Placebo) to Recovery T4/T1 Ratio to 0.9 (time frame: From start of sugammadex or palcebo administration to recovery of T4/T1 ratio to 0.9 (ranging from ~0.5 minutes to ~30 minutes from sugammadex or placebo administration)). 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 NCT00421148, 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 28 Jan 2019.
