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 person who is responsible for the scientific and technical direction of the entire clinical study.

Crohn's disease (CD) is a chronic, relapsing, remitting, systemic disease, which may result in transmural inflammation of the gastrointestinal tract. The precise aetiology is unknown: it is a lifelong disease arising from an interaction between genetic and environmental factors, but predominantly observed in developed countries of the world. CD can affect the entire digestive tract from the mouth to the anus, but the most commonly affected sites are the ileum and the ascending colon . The clinical course of CD is characterized by exacerbations and remissions. Therefore, recurrent inflammation can cause bowel strictures, fistulae (often perianal) or abscesses. Moreover, Crohn's disease (CD) often requires intestinal resection, despite treatment with immunosuppressive and biologic therapies. Surgery in CD is not curative, and post-operative recurrence (POR) is a frequent event. Historically, up to 70% of patients who undergo CD-related resection develop postoperative endoscopic recurrence at or proximal to the surgical anastomosis within 1 year and approximately one-third of patients with CD, who have a first resection, require a second within 10 years. Endoscopic lesions usually precede and correlate with future clinical recurrence (about 20-25% per year), and predict the development of Crohn's disease-related complications and the need for re-intervention. Therefore, endoscopic follow-up 6-12 months after surgery is recommended. Given the association between enteric bacteria and postoperative CD recurrence, antibacterial agents directed against anaerobic bacteria (ornidazole and metronidazole) were shown to be effective in reducing the severity of endoscopic recurrence, but prolonged administration (more than 3 months) of these antibiotics causes significant toxicity, mainly neuropathy and gastrointestinal intolerance. The efficacy of "systemic antibiotics" and the experimental evidence of the central role of luminal flora as an essential factor in the development of post chirurgic CD recurrence provide the rationale for evaluating a locally acting antibiotic like Rifaximin in this condition.
