Comprehensive Assessment of Nutrition and Dietary Intervention in Hypermobile Ehlers Danlos Syndrome (CANDI-hEDS2)

August 4, 2023 updated by: Queen Mary University of London

Comprehensive Assessment of Nutrition & Dietary Intervention in Hypermobile Ehlers Danlos Syndrome (hEDS/HSD): a Personalised Approach: Phase 2 & 3

This study involves a comprehensive nutritional assessment of hEDS participants who have functional gastrointestinal disorders and dietary intervention to broaden their food choices and nutritional intake.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

The impact of diet on symptoms in patients with Hypermobile Ehlers Danlos Syndrome (hEDS/HSD) is widely recognised yet poorly understood. The investigators aim is to assess existing dietary patterns and nutritional status in hEDS/HSD as well as pilot a personalised dietary strategy to optimise nutrition. Participants recruited from EDS UK and a tertiary Neurogastroenterology clinic at the Royal London Hospital will undergo comprehensive nutritional assessment and blood tests. The investigators will then undertake a feasibility study of personalised dietary intervention in select cohort of patients.

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.

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
Measure Description
Time Frame
Number of patients
Time Frame: 3 months
Number of patients who adhere to dietary recommendations based on acceptability of intervention and ease of delivery.
3 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.
