About this study
Official title: Sodium Sulfate/Potassium Sulfate/Magnesium Sulfate Bowel Preparation With and Without Simethicone for Routine Colonoscopy: A Double-blinded Randomized Controlled Trial
The purpose of this study is to investigate Suprep bowel preparation, with and without the anti-gas medication simethicone, in terms of efficacy and patient tolerability in the preparation of patients undergoing routine colonoscopy for colorectal cancer screening.
Read the detailed description
The study will investigate sodium sulfate/potassium sulfate/magnesium sulfate (Suprep), with and without simethicone, in terms of efficacy and patient tolerability in the preparation of patients undergoing routine colonoscopy. Adult ambulatory outpatients who are scheduled for elective routine colonoscopy for colorectal cancer screening will be recruited to participate in the trial. Patients will be randomized to receive either simethicone or placebo in addition to oral sodium sulfate/potassium sulfate/magnesium sulfate solution (Suprep) and will receive verbal and written instruction on administration of solutions. During colonoscopy, three areas of the colon (right colon, transverse colon, and left colon) will be assessed during removal of the colonoscope for overall colon cleansing, presence of bubbles, and degree of haziness; this will be scored by a blinded endoscopist. A separate written patient questionnaire will be used to assess acceptability and tolerability of the preparation, as well as any adverse events.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SimethiconeDrug
Also called Gas-X Infant Drops, Infants Gas Relief, Infants Simethicone, Infants' Mylicon
Patients will be randomized to receive either simethicone or placebo in addition to oral sodium sulfate/potassium sulfate/magnesium sulfate solution (Suprep), and will be blinded to whether they are in the simethicone arm or the placebo arm of the trial. Simethicone and placebo will be prepared as identically-appearing liquid solution (2.4 mL) with the assistance of a pharmacist. The simethicone or placebo solution will then be assigned to patients according to the randomization scheme and samples will be labeled with patient information prior to distribution. Only the pharmacist will participate in the labeling process and know which patients receive simethicone or placebo; administering staff, nurses, physicians, and patients will be blinded to this.
PlaceboDrug
Also called Inert solution
Patients will be randomized to receive either simethicone or placebo in addition to oral sodium sulfate/potassium sulfate/magnesium sulfate solution (Suprep), and will be blinded to whether they are in the simethicone arm or the placebo arm of the trial. Simethicone and placebo will be prepared as identically-appearing liquid solution (2.4 mL) with the assistance of a pharmacist. The simethicone or placebo solution will then be assigned to patients according to the randomization scheme and samples will be labeled with patient information prior to distribution. Only the pharmacist will participate in the labeling process and know which patients receive simethicone or placebo; administering staff, nurses, physicians, and patients will be blinded to this.
sodium sulfate/potassium sulfate/magnesium sulfate solutionDrug
Also called Suprep Bowel Prep Kit
Both arms will receive sodium sulfate/potassium sulfate/magnesium sulfate solution for bowel preparation
| Study group | Role | What they receive |
|---|---|---|
| Simethicone Group | Active comparator | Early in the evening prior to colonoscopy, patients will be instructed to consume one 6 ounce bottle of oral sodium sulfate/potassium sulfate/magnesium sulfate (Suprep) solution (containing sodium sulfate 17.5 grams, potassium sulfate 3.13 grams, and magnesium sulfate 1.6 grams) diluted with 16 ounces of water over one hour. Over the next hour, the patient will be instructed to drink an additional 32 ounces of water. On the day of colonoscopy, the same procedure will be repeated. Patients will take 2.4 mL simethicone in a half glass of water immediately after consuming each dose of the Suprep. All of the bowel preparation solution and required water should be consumed at least 2 hours prior to colonoscopy. Receives: Drug: Simethicone; Drug: sodium sulfate/potassium sulfate/magnesium sulfate solution |
| Placebo Group | Placebo comparator | Early in the evening prior to colonoscopy, patients will be instructed to consume one 6 ounce bottle of oral sodium sulfate/potassium sulfate/magnesium sulfate (Suprep) solution (containing sodium sulfate 17.5 grams, potassium sulfate 3.13 grams, and magnesium sulfate 1.6 grams) diluted with 16 ounces of water over one hour. Over the next hour, the patient will be instructed to drink an additional 32 ounces of water. On the day of colonoscopy, the same procedure will be repeated. Patients will take 2.4 mL of placebo (identical in appearance to simethicone) in a half glass of water immediately after consuming each dose of the Suprep. All of the bowel preparation solution and required water should be consumed at least 2 hours prior to colonoscopy. Receives: Drug: Placebo; Drug: sodium sulfate/potassium sulfate/magnesium sulfate solution |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall bowel cleansing
To be assessed during removal of the colonoscope during the procedure and blinded endoscopist will score using a written questionnaire
Measured: During procedure
Secondary outcomes (2)
Number of patients with adverse effects
A written patient questionnaire will be used to assess patient acceptability and tolerability by recording any adverse effects experienced, including nausea, vomiting, headache, insomnia, bloating, abdominal pain, abdominal discomfort, abdominal cramps or any others.
Measured: Day prior to and day of colonoscopy
Number of patients completing the bowel preparation
A written patient questionnaire will be used to assess compliance by asking if the total prescribed volume of solution was ingested and by recording number of evacuations.
Measured: Day prior to and day of colonoscopy

Questions about this trial
What is this clinical trial studying?
A study testing Simethicone and sodium sulfate/potassium sulfate/magnesium sulfate solution in people with Colorectal Cancer, run by MercyOne Des Moines Medical Center at 2 sites 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 2 inclusion and 11 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: withdrawn, as of the sponsor's last update on 12 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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. Some participants in this study may receive a placebo. 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 was withdrawn before enrolling participants, so there are no results.
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?
Overall bowel cleansing (time frame: During procedure). 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 NCT02523911, which also lists 14 linked publications.
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 12 Feb 2020.
