Study summary

Study around children with inborn errors of metabolism (IEM) and their healthy siblings. Collection of stool and urine to assess contribution of microbiota to disease severity.

Read the detailed description

This study aims to collect biological samples (stool and urine) from children with inborn errors of metabolism, IEM (like UCD (urea cycle disorder), PA (propionic aciduria) and MMA (methylmalonic aciduria) and their healthy siblings.

The main focus of the study is to assess the contribution of the intestinal microbiota to disease severity in children that suffer from different forms of IEM and potentially find microbiota targets that could be used in the design of therapeutic/prophylactic agents.

Study population

The study aims to enroll 40 children that suffer from IEM (UCD, PA, MMA) and their siblings over the course of approximately two years.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Children or siblings of children that have been diagnosed with one of the following diseases: any type of UCD, PA or MMA

Exclusion criteria

Exclusion Criteria:

  • Children or siblings of children that have not been diagnosed with one of the following diseases: any type of UCD, PA or MMA
  • use of an drug or device less than 30 days prior to the study, or current enrollment in another investigational drug or device study less than 30 days prior to the study
  • considered to be poor attendees or unlikely for any reason to be able to comply with the study procedures, in the opinion of the investigator
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Groups and cohorts

  • Patients with IEM

What researchers measure

Primary outcomes

  1. Contribution of micriobiota to disease severity

    Assess contribution of intestinal microbiota to disease severity in children that suffer from different forms of IEM via changes in frequencies, absolute colonization levels or strain identity of microbiota species

    Time frame: 6 months

Secondary outcomes

  1. Disease aggravating microbiota (microbiota target)

    Identify members of the intestinal microbiota (species/strains) that are associated with IEM via differential abundance testing (microbiota target)

    Time frame: 6 months
