Fibres Supplementation in Rheumatoid Arthritis (SUPER-FIBRES)

December 22, 2022 updated by: University Hospital, Montpellier

Supplementation of Rheumatoid Arthritis Patients With Dietary Fibre to Improve Their Gut Microbiota

Design: Randomized, double-blind, placebo-controlled study with 4 weeks of treatment with either fiber supplements or placebo.

Primary outcome: variation in SCFA between baseline and week 4. Secondary outcomes : variations in gut microbiota, disease activity (DAS28, RAID), immune cells (regulatory T and B cells, Th17) and heart-rate variability.

Population: 29 patients with rheumatoid arthritis treated with only csDMARDs and a moderate disease activity will be recruited in each arm and 29 controls with mechanic disease (osteoarthritis, tendinitis).

Collection: Blood, feces, disease activity and heart rate variability will be collected at baseline and week 4.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
87

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 81 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Evaluation of Short-chain fatty acid (SCFA)
Time Frame: 36 months
36 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
