Trial summary

The investigators hypothesize that a novel method for oligosaccharide supplementation, in the form of nutritional bars and/or muesli high in fructans and galacto-oligosaccharides (GOS), will be a safe and tolerable therapeutic intervention in patients with Crohn's disease (CD) in remission.

About this study

Official title: Assessing the Tolerability of Oligosaccharide Supplementation in Patients With Crohn's Disease: A Randomized, Controlled Trial

The investigators hypothesize that a novel method for oligosaccharide supplementation, in the form of nutritional bars and/or muesli high in fructans and galacto-oligosaccharides (GOS), will be a safe and tolerable therapeutic intervention in patients with Crohn's disease (CD) in remission.

Read the detailed description

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 [49]. 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Difference in overall GI symptoms

    The primary outcome will be the difference in overall gastrointestinal symptoms quantified by the VAS, at study completion compared to baseline, averaged over the 5-days in which the diet diaries are being completed among the 3 study groups.

    Measured: 5 days

Secondary outcomes (6)
  1. Tolerability assessment including overall gastrointestinal symptoms and specific symptoms

    Secondary outcomes concerning tolerability will include differences in the individual gastrointestinal symptoms (abdominal bloating, abdominal pain, gut rumbling, flatulence) quantified by the VAS at study completion compared to baseline, averaged over the 5-days in which the diet diaries are being completed among the 3 study groups.

    Measured: 4 weeks

  2. Fatigue assessment

    Secondary endpoints concerning differences in the scores of the overall FIS (fatigue impact scale) and sub-categories (physical, cognitive, psychosocial) at study completion compared to baseline in all 3 study groups

    Measured: 4 weeks

  3. Quality of Life Assessment

    Secondary endpoints concerning differences in physical components summary (PCS) and the mental component summary (MSC) scores at study completion compared to baseline in all 3 study groups respectively

    Measured: 4 weeks

  4. Mood Assessment

    Secondary endpoints concerning mood that will include differences in state anxiety, state curiosity, state anger, and state depression scores of the STPI at study completion compared to baseline in all 3 study groups respectively

    Measured: 4 weeks

  5. Disease Activity Asessment

    The proportion of participants who relapse, as well as the time to relapse at study completion between groups.

    Measured: 4 weeks

  6. Adherence Assessment

    Adherence will be estimated and compared between groups at study completion

    Measured: 4 weeks
