About this study

Official title: Comparison of Single-dose (Morning) Low-volume Polyethylene Glycol Plus Bisacodyl Versus Split-dose Polyethylene Glycol for Bowel Preparation Efficacy in Patient Receiving Morning Colonoscopy

Colonoscopy is the best method to detect colorectal cancer and colonic polyps. Studies showed that adenoma detection rate positive correlation with good bowel preparation which makes bowel preparation an important issue. Hence, investigators conduct a clinical trial about adding another laxative agent to morning single dose low-volume PEG. To see if this new regimen could have non-inferior efficacy and lower life/sleep impact compared with standard regimen.

Read the detailed description

Colorectal cancer incidence rate has increased in recently years, and colorectal cancer has come to the top of cancer incidence ranking of Taiwan. Colonoscopy is the best method to detect colorectal cancer and colonic polyps. Studies showed that adenoma detection rate positive correlation with good bowel preparation. That makes bowel preparation an important issue. Polyethylene Glycol (PEG) is widely used for bowel preparation for it efficacy and safety. However, there are many different adjunctive, dose, timing of administration in PEG preparation. Some may decrease patient tolerability due to large fluid volume, and some may influence patient's life and sleep quality when performing bowel preparation. Here, investigators conduct a clinical trial about adding another laxative agent to morning single dose low-volume PEG. To see if this new regimen could have non-inferior efficacy and lower life/sleep impact compared with standard regimen.

What participants receive

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

  • Polyethylene glycol and bisacodylDrug

    Also called Dulcolax®, Klean-prep®

    Intervention: Take 3 tablets (15mg) of stimulant laxatives Dulcolax® (bisacodyl) at 10pm the day before examination. Take two pack of osmotic laxative Klean-prep® powder (Polyethylene glycol) mixed with 2000ml water at 5am on the morning of examination.

  • Split-dose polyethylene glycolDrug

    Also called Klean-prep®

    Take two pack of Klean-prep® powder mixed with 2000ml water at 6pm before the day of examination, and take another two pack of osmotic laxative Klean-prep® powder mixed with 2000ml water at 5am on the examination day.

Study groups in NCT03248726
Study groupRoleWhat they receive
Polyethylene glycol and bisacodylExperimentalIn order to decrease the dose and frequency of polyethylene glycol, we added bisacodyl at the night before examination to facilitate the action of polyethylene glycol given solely in the morning of examination.
Receives: Drug: Polyethylene glycol and bisacodyl
Split-dose polyethylene glycolActive comparatorThe standard regimen of polyethylene glycol was used in this group. The participant of this arm receives polyethylene glycol in the evening before examination and the morning of examination .
Receives: Drug: Split-dose polyethylene glycol

What is being measured

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

  1. The Ottawa Bowel Preparation Scale

    Examiner will fill a case report form out after performing a colonoscopy. Score below or equal to 6 will be classified as "good preparation".

    Measured: Within 24 hours after colonoscopy

Secondary outcomes (1)
  1. Life disturbance

    Evaluate patients life disturbance with a questionnaire before performing a colonoscopy. The questionnaire including side effect, sleep quality, interference of life/work, and tendency of same bowel preparation method at next colonoscopy.

    Measured: 30 minutes before patient receive colonoscopy

Questions about this trial

What is this clinical trial studying?

A study testing Polyethylene glycol and bisacodyl and Split-dose polyethylene glycol in people with Bowel Preparation, run by Taipei Medical University WanFang Hospital at 1 site in Taiwan.

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 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 29 Oct 2019. 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 Taiwan. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The Ottawa Bowel Preparation Scale (time frame: Within 24 hours after colonoscopy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Oct 2019.
