Clinical Study Comparing PillCam® Crohn's Capsule Endoscopy to Ileocolonoscopy (IC) Plus MRE for Detection of Active CD in the Small Bowel and Colon in Subjects With Known CD and Mucosal Disease


About this study

This study will evaluate the efficacy of capsule endoscopy (CE) versus ileocolonoscopy (IC) plus MRE for detection of active Crohn's disease (CD) in the small bowel in subjects with known CD and mucosal disease. The primary objective of the study is to assess the accuracy of CE versus IC plus MRE for detecting active CD, by visualizing the small bowel and colon in subjects with known CD and mucosal disease. There will be assessment of mucosal disease activity at baseline and 6- and 12- month follow ups. Patient satisfaction questionnaires will be completed at baseline, 6- and 12- month follow ups along with a Quality of Life questionnaire at 12 month follow up. Concomitant medication and adverse events information will be collected baseline and 3-, 6-, 9- and 12 month follow ups.

  • Subject with a diagnosis of gastroparesis or small bowel or large bowel dysmotility.
  • Subjects with a history of small bowel or colonic resection.
  • Subject with any current condition believed to have an increased risk of capsule retention such as suspected or known bowel obstruction, stricture, or fistula.

  • Subject is considered to be a part of a vulnerable population (eg. prisoners or those without sufficient mental capacity).
  • Subject has a known contraindication to MRE or IC.
  • Subject has participated in a drug or device research study within 30 days of enrollment that may interfere with the subject's safety or ability to participate in the study.
  • Subject has any medical condition that would make it unsafe for them to participate, per Investigator's descretion
