Inclusion criteria

  • Has a (BMI) \< 40 kg/m2.
  • Is categorized as ASA Physical Status Class 3 or 4, as determined by the Investigator.
  • Has a planned surgical procedure that requires NMB with either rocuronium or vecuronium.
  • Has a planned surgical procedure (e.g., gastrointestinal, urologic, or laparoscopic) that in the opinion of the investigator does not preclude maintenance of moderate or deep depth of NMB throughout the case.
  • If female who is not of , is one of the following: (1) ; (2) has had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy, or bilateral tubal ligation/occlusion at least 6 weeks prior to screening; (3) has a congenital or acquired condition that prevents childbearing; or (4) is undergoing surgical sterilization (e.g., hysterectomy or tubal ligation) as the planned surgical procedure associated with participation in this study.
  • If female who is sexually active and of , agrees to use a medically accepted method of through seven days after receiving protocol-specified medication. Abstinence (relative to heterosexual activity) can be used as the sole method of contraception if it is consistently employed as the subject's preferred and usual lifestyle and if considered acceptable by local regulatory agencies and Ethics Review Committees/Institutional Review Boards.
  • Is able to provide (or the participant's legally authorized representative, in accordance with local requirements), written for the trial. The participant or legally authorized representative may also provide consent for Future Biomedical Research.

Exclusion criteria

Exclusion Criteria:

Terms in these criteria, in plain language(10)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Percentage of Participants With Treatment-Emergent Sinus Bradycardia Events

    The percentage of participants experiencing treatment-emergent sinus bradycardia events was identified with continuous electrocardiogram (ECG) monitoring. Treatment-emergent sinus bradycardia were defined as a heart rate \<60 bpm that has also decreased more than 20% compared to participant baseline heart rate value, sustained for at least 1 minute after administration of study intervention. Treatment-emergent sinus bradycardia events may or may not have been considered an adverse event (AE), as determined by investigator judgment.

    Time frame: Up to approximately 35 minutes post-administration

  2. Percentage of Participants With Treatment-Emergent Sinus Tachycardia Events

    The percentage of participants experiencing treatment-emergent sinus tachycardia events was identified with continuous ECG monitoring. Treatment-emergent sinus tachycardia is defined as a heart rate ≥100 bpm that has also increased more than 20% compared to participant baseline heart rate value, sustained for at least 1 minute after administration of study intervention. Treatment-emergent sinus tachycardia events may or may not have been considered an AE, as determined by investigator judgment.

    Time frame: Up to approximately 35 minutes post-administration

  3. Percentage of Participants With Other Treatment-Emergent Cardiac Arrhythmia Events

    The percentage of participants experiencing other treatment-emergent cardiac arrhythmia events was identified with continuous ECG monitoring. Other treatment-emergent cardiac arrhythmias were defined as new or worsening arrhythmias (e.g., atrial fibrillation, atrial tachycardia, ventricular fibrillation, or ventricular tachyarrhythmia), sustained for at least 1 minute after administration of study intervention. Worsening arrhythmia events may or may not have been considered an AE, as determined by investigator judgment.

    Time frame: Up to approximately 35 minutes post-administration

  4. Percentage of Participants Experiencing an Adverse Event (AE) Up To 7 Days After Administration of Study Intervention

    As per the protocol primary analysis, the percentage of participants experiencing an AE up to 7 days after administration of study intervention was reported. An AE was defined as any untoward medical occurrence in a participant which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE.

    Time frame: Up to 7 days

  5. Percentage of Participants Experiencing a Serious Adverse Event (SAE) Up To 7 Days After Administration of Study Intervention

    As per the protocol primary analysis, the percentage of participants experiencing an SAE up to 7 days after administration of study intervention was reported. An SAE was an adverse event that: resulted in death; was life threatening; resulted in persistent or significant disability or incapacity; resulted in or prolonged an existing inpatient hospitalization; was a congenital anomaly or birth defect; was an other important medical event, was a cancer; or was associated with an overdose.

    Time frame: Up to 7 days

  6. Percentage of Participants Experiencing an Event of Clinical Interest (ECI) Up To 7 Days After Administration of Study Intervention

    As per the protocol primary analysis, the percentage of participants experiencing an ECI up to 7 days after administration of study intervention was reported. ECIs were a discrete set of both AEs and SAEs, specifically designated as such for the trial. For the purposes of this investigation, ECIs included 1) drug-induced liver injury; 2) clinically-relevant arrhythmias, inclusive of bradycardia and tachycardia defined as events necessitating intervention, as determined by investigator judgment; and 3) instances of hypersensitivity and/or anaphylaxis adjudicated by an external expert Adjudication Committee. A participant could have experienced more than one type of ECI.

    Time frame: Up to 7 days

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2017 to primary completion in Sep 2019, 20 months.

Results were first posted in Oct 2020, 1 year 1 month after primary completion.

Of 24 phase 4 interventional studies under Arrhythmias, Cardiac, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 57. This study's 20 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 8, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
