At baseline, subjects with known CD on routine evaluation (e.g. history, physical exams, labs) and a recent history of mucosal disease (within the last 2 years and diagnosis based on radiologic, endoscopic, or histologic findings) will undergo Magnetic Resonance Enterography (MRE), Capsule Endoscopy (CE) and Ileocolonoscopy (IC), to assess presence or absence of CD across the small and large bowel. Also, at baseline the following assessments will take place: Laboratory tests, Pregnancy test, Concomitant medications, Patient satisfaction questionnaire, Quality of life questionnaire and Adverse Events.
