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 disease, disorder, syndrome, illness, or injury that is being studied.
Subjects age >/= 19 years with the diagnosis of CD for >/= 6 months, currently in remission based on the Harvey-Bradshaw Index score (=4 points) and C-reactive protein (<5 mg/L) will be recruited from two academic hospitals and affiliated gastroenterology outpatient clinics (St. Paul's Hospital, Vancouver, British Columbia, Canada; Alfred Hospital, Melbourne, Victoria, Australia). The study is a randomized, double-blind, placebo-controlled trial that consist of a 2-week run-in period followed by a 4-week study period. Prior to study entry, a screening visit will be required for all potential participants. If a participant meets the inclusion criteria, they will be randomized to either a placebo (0.55 g total fructans/GOS), a moderate oligosaccharide group (3.25 g total fructans/GOS) or a high oligosaccharide group (5.43 g total fructans/GOS) through a computed-generated scheme within each respective center. During the run-in period, enrolled subjects will undergo the following: 1) Laboratory analyses (CBC, routine biochemistry, CRP and fecal calprotectin); 2) Stool collection for fecal calprotectin analysis; 3) tolerability assessment including overall gastrointestinal symptoms and specific symptoms (abdominal bloating, abdominal pain, gut rumbling, flatulence) utilizing a 100mm visual analogue scale (VAS, 0 = no symptoms; 100 = worst symptoms ever experienced); 4) fatigue assessment utilizing a multi-dimensional fatigue impact scale (FIS); 5) health-related quality of life (HRQOL) assessment utilizing the Short Form 36-Item Health Survey (SF-36) and 6) Mood assessment utilizing the Spielberger State-Trait Personality Inventory (STPI). Participants will also meet with a registered dietitian to quantify baseline oligosaccharide consumption by completing a prospective 5-day diet diary alongside a validated food frequency questionnaire (FFQ), the Monash University Comprehensive Nutritional Assessment Questionnaire (CNAQ) that assesses oligosaccharide intake in addition to the usual nutrients . Once the initial dietary assessment is complete, participants will begin up-titration of their oligosaccharide supplementation in a step-wise fashion until they reach their required daily amounts defined by their treatment group allocation. Once this is achieved, they will enter the 4 weeks of treatment or at time of relapse. Participants will undergo re-assessment during the study period at 2 weeks (Visit #3), and at study completion (Visit #4). If a participant undergoes a CD flare during the run-in period, they will be withdrawn from the study. The end point of the study will be at 4 weeks of treatment or at time of relapse.
