Colon Cancer Clinical Trial
Colorectal Cancer Screening in Cystic Fibrosis
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).
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, greater than 3 months duration between stool-based testing and colonoscopy will be considered a protocol deviation.
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 months of submission of the stool sample.
Adults eligible for routine colon cancer screening: Adults with CF ages 40 - 75 years of age without history of transplant, or adults with CF age 30 - 75 who have had a transplant
Cystic Fibrosis diagnosis, defined by a sweat chloride test result ≥ 60 mmol/L (may be of historic value), and/or documented CF-causing CFTR mutations and clinical features of CF
Capable of understanding the purposes and risks of the study in English or Spanish and willing to participate and sign informed consent
Referred for screening or surveillance colonoscopy for CRC (current standard of care) and willing to undergo colonoscopy and stool testing
Able to access the Internet to complete self-administered surveys
Any condition that, in the opinion of the site PI, introduces undue risk by participating in this study
Incapable of understanding the purposes of the study or informed consent for any reason
Active inflammatory bowel disease as defined by a prior diagnosis of Crohn's Disease or Ulcerative Colitis, based on both clinical and histopathologic findings and the individual currently on medical therapy for Crohn's disease or Ulcerative Colitis.
Personal history of colon cancer diagnosis and treatment within 5 years of enrollment
Symptoms that merit colonoscopy for diagnostic purposes rather than as screening for CRC
