This multi-center study will compare multi-target DNA and quantitative FIT stool-based testing to colonoscopy in individuals with Cystic Fibrosis (CF) undergoing colon cancer screening with colonoscopy. The primary endpoint is detection of any adenomas, including advanced adenomas and colorectal cancer (CRC).
A Multi-Center Study of Non-Invasive Colorectal Cancer Evaluation in Cystic Fibrosis (NICE-CF)
NICE-CF is a cross-sectional, multi-center study comparing stool-based testing (multi-target DNA test and quantitative FIT test) to standard of care colonoscopy for colorectal cancer (CRC) screening in people with CF. The study includes an enrollment visit, two stool samples completed at home, a clinical screening colonoscopy, and three participant surveys which will be completed at enrollment or remotely.
The total duration of participant participation will be 3-12 months, depending on the timing of the completion of the stool samples and the participant's colonoscopy. The targeted participant timeline is 3 months from enrollment to the completion of a clinical screening colonoscopy. To allow for varying site-specific clinical colonoscopy scheduling delays and COVID delays in scheduling, the duration of time between submitting stool samples and screening colonoscopy may extend up to 12 months for inclusion of data in the study. However, participating sites must notify the DCC to obtain preapproval for greater than 3 months duration between stool-based testing and colonoscopy.
CF patients who are eligible for CRC screening will either be enrolled during an in-person CF clinic visit or via phone/video if clinic visits are taking place remotely. Participants will be asked to perform stool sample collection at home, and then complete their colonoscopy within three to twelve months of submission of the stool sample.
