About this study
Official title: Mechanisms of Type 1 Diabetes Endophenotypes, by Cluster Analysis
The goal of this observational study consists of performing cluster analysis to decipher underlying disease mechanisms of type 1 diabetes in children and young adults.
To this end, we will combine clinical, laboratory, genetic, transcriptomic, and metabolomic datasets of an extensively phenotyped cohort of children and young adults with type 1 diabetes. We will also assess the risk for cardiovascular diseases in this most vulnerable diabetes cohort.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Genome sequencingGenetic
Also called Lipidomic, Metabolomic, Transcriptomic, Mixed meal tolerance test
100 extensively phenotyped pediatric and young adult patients for genotyping, metabolomic and lipidomic analyses. Polygenic risk scores for type 1 diabetes and cardiovascular disease will be performed.
For patients older than 6 years who agree to do a second visit (optional), a Mixed Meal Tolerance Test (MMTT: the gold standard for assessing beta cell function) will be done as well as transcriptomic analysis.

| Control | 50 control patients Receives: Genetic: Genome sequencing |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cluster analysis to decipher underlying mechanisms of type 1 diabetes
We will combine clinical, laboratory, genetic, transcriptomic, and metabolomic datasets of an extensively phenotyped cohort of type 1 diabetes patients (Children and young adults).
We will create clinical and genetic correlates with the following clinical parameters: Age at diabetes onset (years), disease duration (years), BMI (kg/m2), diabetes autoantibodies, C-peptide level (pmol/l) and decline over time, HbA1c (%), insulin dose (U/kg/d), ketoacidosis at disease onset (y/n), lipid levels (Total cholesterol, triglycerides, HLD, LDL, Lipoprotein(a)), macro- and microvascular complications, ethnicity, family history for diabetes, associated autoimmune diseases (e.g., autoimmune thyroiditis or celiac disease) and mixed meal tolerance test.
Measured: blood sampling and analyses

Questions about this trial
What is this clinical trial studying?
An observational study of Type 1 Diabetes Mellitus and Genetic Predisposition to Disease, run by Pediatric Clinical Research Platform at 1 site in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 13 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Valerie VS Schwitzgebel, MD (+41 22 372 45 90, valerie.schwitzgebel@unige.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cluster analysis to decipher underlying mechanisms of type 1 diabetes (time frame: blood sampling and analyses). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2023.
