Study summary

The goal of this clinical trial is to compare two sedation regimens-remimazolam and midazolam-for colonoscopy in adult patients with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis.

The main questions it aims to answer are:

  • Does remimazolam provide patient satisfaction that is non-inferior to midazolam during colonoscopy?
  • Does remimazolam allow faster recovery and discharge readiness compared to midazolam?

Researchers will compare sedation with remimazolam plus fentanyl to sedation with midazolam plus fentanyl to see if remimazolam improves patient experience and procedural efficiency.

Participants will:

  • Receive either remimazolam or midazolam, each combined with fentanyl, during their scheduled colonoscopy
  • Complete a short questionnaire to rate their satisfaction after the procedure
  • Be assessed for recovery using a standardized discharge score at 10 and 20 minutes after the procedure

Terms in these criteria, in plain language(4)

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.

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.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

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.

Study arms

  • Active comparator
    Arm 2 (Remimazolam + Fentanyl)

    ARM 2: Participants receive intravenous remimazolam plus fentanyl for procedural sedation during colonoscopy

    Drug: Intravenous remimazolam (5 mg initially, with optional 2.5 mg boluses) plus fentanyl (100 mcg) for procedural sedation.

  • Active comparator
    Arm 1 (Midazolam + Fentanyl)

    Arm Description: ARM 1: Participants receive intravenous midazolam plus fentanyl for procedural sedation during colonoscopy.

    Drug: Intravenous midazolam (3 mg initially, with optional 3 mg boluses) plus fentanyl (100 mcg) for procedural sedation.

Interventions

  • DrugIntravenous remimazolam (5 mg initially, with optional 2.5 mg boluses) plus fentanyl (100 mcg) for procedural sedation.

    \- Remimazolam + Fentanyl IV fentanyl 100 mcg is given first, followed after 1 minute by IV remimazolam 5 mg over 1 minute. Additional 2.5 mg boluses may be given every 2 minutes as needed. Colonoscopy starts 1 minute after sedation. Vital signs are monitored throughout.

  • DrugIntravenous midazolam (3 mg initially, with optional 3 mg boluses) plus fentanyl (100 mcg) for procedural sedation.

    \- Midazolam + Fentanyl (≤1000 caratteri) IV fentanyl 100 mcg is given first, followed after 1 minute by IV midazolam 3 mg over 1 minute. Additional midazolam may be administered based on clinical judgment. Colonoscopy starts 1 minute after sedation. Vital signs are monitored throughout.

What researchers measure

Primary outcomes

    Proportion of patients reporting at least "satisfied" with sedation (Likert scale 1-4, 3 or 4 points)

    Time frame: Immediately post-procedure

Secondary outcomes

    Proportion reporting "very satisfied" (Likert scale 1-4, 4 points)

    Time frame: Immediately post-procedure

  2. Incidence of treatment-emergent adverse events

    Proportion of patients experiencing any of the following adverse events (occurring after the administration of the study drug): * Desaturation: peripheral oxygen saturation (SpO₂) below 90% * Tachycardia: heart rate greater than 100 bpm * Bradycardia: heart rate less than 50 bpm * Hypotension: systolic blood pressure below 90 mmHg

    Time frame: Throughout the observation period (i.e., until discharge)

  3. Discharge readiness 10'

    Proportion of patients ready for discharge (PADSS ≥9)

    Time frame: 10 minutes post-procedure

  4. Dischatge readiness 20'

    Proportion of patients ready for discharge (PADSS ≥9)

    Time frame: 20 minutes post-procedure

  5. Maximum net benefit

    Proportion of patients reportinng "very satisfied" with sedation (Likert scale 1-4, 4 points) + ready for discharge (PADSS ≥9)

    Time frame: 10 minutes post-procedure

Other outcomes

  1. Endoscopy metrics - cecal intubation rate

    Percentage of procedures where the endoscope successfully reaches the cecum and can be visually confirmed by inspecting the appendiceal orifice

    Time frame: During procedure

  2. Endoscopy metrics - cecal intubation time

    Time from the insertion of the colonoscope tip into the anal verge until reaching the cecal base

Start is estimated for Sep 2025; primary completion for Sep 2025, 0 months later.

Of 33 non-industry phase 4 interventional studies under Inflammatory Bowel Diseases, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 30 and three quarters within 63. This study's planned 0 months is below that.

Counting every sponsor, half of 38 studies reached it within 38 months; a quarter within 21 and three quarters within 63.

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 Sep 8, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
