About this study

Official title: Comparison of Efficacy of Sugammadex Versus Neostigmine in Reversing Neuromuscular Blocks in Patients Having Outpatient Endoscopic Retrograde Cholangiopancreatography (ERCP). A Randomized, Double-Blinded Trial

The investigators propose a single-center, assessor-Blinded, parallel group randomized trial to compare the efficacy of reversal of rocuronium induced neuromuscular blockade by sugammadex versus neostigmine in patients undergoing Endoscopic retrograde cholangiopancreatography at Cleveland Clinic Fairview Hospital.

Read the detailed description

The investigators propose a single-center, assessor-blinded, parallel group randomized trial to compare the efficacy of reversal of rocuronium induced neuromuscular blockade by sugammadex versus neostigmine. Participating patients and outcome assessors will be blinded to group assignment. The anesthesiologists who assume anesthesia care will not be blinded to group assignment.

American Society of Anesthesiologists (ASA) physical status 3 and 4 adults scheduled for elective outpatient ERCP procedure with general anesthesia at Cleveland Clinic Fairview Hospital will be included in the study. Patients will be excluded if they have suspected difficult airway, neuromuscular disorders, end-stage renal disease requiring hemodialysis, are allergic to fentanyl, neuromuscular blocking drugs or neuromuscular reversal drugs, or are pregnant or breastfeeding.

Eighty patients scheduled for outpatient ERCP with general anesthesia and rocuronium-induced muscle relaxation will be randomized 1:1 to: 1) reversal by sugammadex; or 2) reversal by neostigmine. Randomization will be stratified by 2 factors: (1) patient's age (older than 60 versus younger than 60) and (2) diagnostic vs. interventional procedures. Randomization will be based on computer generated codes that will be maintained in web-based system until shortly before induction of anesthesia, thus concealing allocation so long as practical.

Being tested
2 mg/kg sugammadex, 0.07 mg/kg neostigmine

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 2 mg/kg sugammadexDrug

    Also called All participants will be given rocuromium for neuromuscular blocks during the procedure. Per randomization, patients in this group will be reversed with 2 mg/kg sugammadex.

  • 0.07 mg/kg neostigmineDrug

    Also called All participants will be given rocuromium for neuromuscular blocks during the procedure. Per randomization, patients in this group will be reversed with 0.07 mg/kg neostigmine (to a maximum of 5 mg).

    All participants will be given rocuromium for neuromuscular blocks during the procedure. Per randomization, patients in this group will be reversed with 0.07 mg/kg neostigmine (to a maximum of 5 mg).

What is being measured

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

  1. Time required from reversal of neuromuscular block to discharge readiness

    To assess the time required from reversal of neuromuscular block to discharge readiness in patients randomized to sugammadex or neostigmine.

    Measured: First 24 hours after reversal of neuromuscular block

Secondary outcomes (1)
  1. Incidence of postoperative nausea and vomiting (PONV) in patients randomized to sugammadex or neostigmine.

    Incidence of postoperative nausea and vomiting (PONV) in patients randomized to sugammadex or neostigmine.

    Measured: 2 hours of post anesthetic recovery

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 2 mg/kg sugammadex and 0.07 mg/kg neostigmine in people with Neuromuscular Blocks, run by The Cleveland Clinic at 1 site in United States.

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 3 inclusion and 8 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: looking for participants now, as of the sponsor's last update on 15 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Sabry Ayad, MD (216-476-7052, Saayad@ccf.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time required from reversal of neuromuscular block to discharge readiness (time frame: First 24 hours after reversal of neuromuscular block). 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 NCT06136585, 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 15 Dec 2025.
