Bowel Prep Options for Colorectal Cancer Screening
(COOP SIT Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to compare two bowel prep methods for individuals scheduled for a colonoscopy: low-volume tablets (Suflave/Sutab) and a traditional liquid solution (Golytely). Researchers seek to determine patient preference, assess tolerance, and evaluate the effectiveness of each method in preparing the colon. Participants will complete surveys before and after their colonoscopy to share their experiences. Adults with an upcoming colonoscopy who understand English or Spanish may be suitable for this trial. Both prep methods have FDA approval, ensuring no added health risks. As a Phase 4 trial, this research explores how these FDA-approved methods benefit more patients, offering an opportunity to contribute to improving colonoscopy preparation.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What is the safety track record for these treatments?
Research has shown that both Sutab and Suflave are safe for adults to use before a colonoscopy to clean out the bowel. Sutab, available in tablet form, may cause stomach issues like nausea in about 52% of users. These issues are common but usually not serious for most people.
Suflave, a liquid option, is also effective, with about 35% of users experiencing mild discomfort. These reactions are generally easy to manage.
Both Sutab and Suflave have FDA approval for colon cleaning, indicating their safety for this purpose. Prospective trial participants should know that these treatments are widely used and tolerated by many. Always consult a healthcare provider about any concerns to find the best option.12345Why are researchers enthusiastic about this study treatment?
Researchers are excited about these bowel prep options because they offer varied and potentially more palatable ways to prepare for a colonoscopy. Golytely, a common choice, requires drinking a large volume of liquid, which can be challenging for many. Sutab, on the other hand, is a tablet-based option that might be easier to consume, especially for those who struggle with liquid preps. Sulfave stands out with its lemon-lime taste and low volume, potentially making it more tolerable. These new options aim to improve patient comfort and compliance, which are crucial for effective colorectal cancer screening.
What evidence suggests that this trial's bowel preparation methods could be effective for colorectal cancer screening?
This trial will compare different bowel preparation options for colorectal cancer screening. Studies have shown that Sutab, one of the treatments participants may receive, effectively cleans the bowel before a colonoscopy, with about 92% of participants achieving a clean colon. Research indicates that Sutab works as well as other common methods and remains effective even for individuals with constipation. Another treatment option in this trial, Sulfave, requires drinking less liquid and also performs well, with an 89% success rate. This preparation aids doctors in identifying issues like polyps, which are growths in the colon that can become cancerous. Both Sutab and Sulfave are safe and effective at cleaning the colon, facilitating the detection of any problems by doctors.56789

SUTAB comes in a kit that contains two medication bottles and a cup for water. Each bottle contains 12 tablets (pills). You'll take 12 pills (one bottle) with water from the cup the night before your exam. Later that evening, drink two more cups of water. Fill the cup to the line each time. Then, six hours before your exam, repeat all three of those steps.
Suflave is a combination, osmotic prescription laxative that may be used to cleanse the bowel in preparation for colonoscopy in adults. Suflave contains polyethylene glycol 3350, sodium sulfate, potassium chloride, magnesium sulfate, and sodium chloride, and is supplied as a powder that is mixed with a low volume of water before consuming. It tastes like a lemon-lime sports drink. Drink 8 ounces of the solution every 15 minutes until the bottle is empty, and then drink an additional 16 ounces of water during the evening. One dose of Suflave is equal to one bottle plus one flavor-enhancing packet.
GoLYTELY is a prescription medicine used by adults to clean the colon before a colonoscopy or barium enema X-ray examination. GoLYTELY cleans your colon by causing you to have diarrhea (loose stools). Cleaning your colon helps your healthcare provider see the inside of your colon more clearly during your colonoscopy. Drink reconstituted solution at a rate of 8 ounces every 10 minutes, until 4 liters are consumed, or rectal effluent is clear.
