The Impact of GLP Medication on Colonoscopy Bowel Preparation Quality Phase 4 132 Single Dose

Recruiting
Clinical Trial NCT07127354 is designed to study Treatment for GLP - 1, Bowel Preparation for Colonoscopy. It is a Phase 4 interventional study that is recruiting, having started on 1 August 2025, with plans to enroll 132 participants. Led by The Cleveland Clinic, it is expected to complete by 1 August 2026. The latest data from ClinicalTrials.gov was last updated on 4 December 2025.
Brief Summary

The goal of this clinical trial is to learn how GLP-1 and GIP agonists effect bowel preparation in patients scheduled for colonoscopies. The main questions it aims to answer are:

  • Does GLP-1 and GIP agonist increase the rate of inadequate bowel preparation?
  • Does the quality of bowel preparation differ in patients who hold vs. those who continue a single dose of their GLP-1 or GIP agonist medication?
  • Are there a...

Accepts Healthy Volunteers
Yes
  • Adult patient (Age 18 years or older)
  • Patient scheduled for outpatient screening, surveillance, or diagnostic colonoscopy
  • Using a GLP-1 or GIP agonist at a stable dose for at least one month

  • Unable to provide informed consent, e.g., dementia

  • Patient refuses the USMSTF recommended bowel cleansing regimen for patients with diabetes or obesity (split-dose 4 liters polyethylene glycol + 15 mg bisacodyl the afternoon before; low residue diet 3 days before colonoscopy; clear liquid diet the day before colonoscopy)

  • Risk factors for inadequate bowel preparation besides diabetes and obesity with a likelihood ratio of 1.6 or greater:

    3. Dementia
    4. Tricyclic antidepressant use
    5. Opioid use
    6. Gastroparesis* or suspected gastric outlet obstruction on pre-procedure imaging (*defined based on a documented 4-hour solid phase gastric emptying study or prior history of retained gastric contents during upper endoscopy)
    7. Previous colorectal surgery
    8. Prior history of inadequate bowel preparation
