Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

The disease, disorder, syndrome, illness, or injury that is being studied.
The aim of this study is to evaluate the applicability of SBCCE, MREC and US for diagnosing ulcer healing after medical treatment in patients with symptomatic CD compared to the current gold standard (ileocolonoscopy). This is a prospective, blinded, multicenter study. Patients are recruited from 3 centers in the Region of Southern Denmark managing adult patients with inflammatory bowel diseases. Each patient goes through a standardized work-up including medical history, physical examination, C-reactive protein, fecal calprotectin, ileocolonoscopy, SBCCE, MREC and US before and 10-12 weeks after medical treatment with corticosteroids or biological therapy (Infliximab, Adalimumab, Vedolizumab or Ustekinumab). All examinations are reviewed and described in a standardized fashion. The radiologists and physicians describing SBCCE, MREC, and US are blinded to the findings at ileocolonoscopy and the other imaging modalities. Ileocolonoscopy serves as the diagnostic gold standard, and endoscopic disease activity is assessed with SES-CD. LOGISTICS: Patients go through an accelerated diagnostic work-up at inclusion and after 10-12 weeks of medical treatment. In patients undergoing their first diagnostic work-up, ileocolonoscopy with biopsies is performed last to avoid false positive lesions at SBCCE. In patients with an established diagnosis, examinations can be performed in a random order provided that tissue samples are not taken during ileocolonoscopy. All diagnostic procedures should be completed within two weeks. If one imaging modality is contraindicated it is classified as "not performed". If ileocolonoscopy (gold standard) is contraindicated, the patient is excluded from the study. All radiological examinations are performed in the Department of Radiology, Lillebaelt Hospital Vejle. Ileocolonoscopy and SBCCE are performed at the local gastroenterology department. During the pre- and post-treatment assessment, radiological examinations and SBCCE are analyzed by physicians blinded to the result of ileocolonoscopy and the other bowel examinations. However, at the post-treatment assessment, physicians are not blinded to the pre-treatment examinations. After completing all diagnostic procedures, the treating gastroenterologist is provided with the results of SBCCE, MREC and US. EXTENDED ULTRASOUND STUDY: Patients are scheduled for additional US procedures after 2 and 4 weeks. Procedures are performed without blinding, i.e. the physician is aware of the results of the pre-treatment assessment and the preceding US examinations. If the bowel wall normalizes at week 2, the subsequent procedure is cancelled. Fecal calprotectin is measured before each US procedure.
Diagnostic Test: - Diagnostic work-up
Patients are examined with all modalities. MR enterocolonography, ultrasound, and small bowel capsule endoscopy are compared against ileocolonoscopy (gold standard).
