Gut Microbiome and Obesity (MATOMS)

July 1, 2020 updated by: Roberto Berni Canani, Federico II University

Gut Microbiome As Target of Intervention Against Obesity and Metabolic Syndrome

Pediatric obesity is a risk factor for the onset of obesity in adulthood and is a risk factor for various chronic non-communicable diseases. Metabolic syndrome (MS) is the name for a group of risk factors that increase cardiovascular risk and other health problems characterized by the presence of abdominal obesity, dyslipidemia, hyperglycaemia and high blood pressure. Numerous preclinical and clinical data suggest a potential role of the intestinal microbiota in these diseaes. Unfortunately, comparative studies of the gut microbiota are still scarce in pediatric subjects suffering from obesity than obesity complicated by MS. The aim is to study the metagenomics and metabolomics characteristics of the intestinal microbiota in obese children/adolescents with or without MS, that could provide useful data for innovative intervention strategies for these conditions.

Study Overview

Status

Status

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

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.

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
Concentration of metagenomic characteristics of the intestinal microbiota in subjects with obesity, obesity complicated by metabolic syndrome and healthy controls
Time Frame: at enrollment
Evaluation of gut microbiota composition
at enrollment

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.
Outcome Measure
Measure Description
Time Frame
Concentration of metabolomic characteristics of the intestinal microbiota in subjects with obesity, obesity complicated by metabolic syndrome and healthy controls

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2020

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
