Clinical Trial Summary

Connective tissue diseases (CTD) or systemic autoimmune diseases (SADs) as they are known today are a group of chronic inflammatory conditions with autoimmune aetiology with few treatment options and difficult diagnosis.Brest team contribute to performe a new classification of the following systemic autoimmune diseases in a European Union's Seventh Framework Programme. The aim of this research consiteis to reclassify the individuals affected by SADs into molecular clusters instead of clinical entities through the determination of molecular profiles using several "Omics" techniques.


Description:

The overall objective of the PRECISESADS IMI project is to reclassify the individuals affected by SADs into clusters of molecular, instead of clinical entities through the determination of molecular profiles using several "-omics" techniques. The identification of the clusters relies on a cross sectional (CS) cohort/protocol where 2666 individuals (2000 patients and 666 controls) including a sub-study of 288 deeply characterized individuals (240 patients and 48 controls) are to be recruited. In parallel a longitudinal inception cohort/protocol will be started in order to further explore the clinical relevance of the identified clusters and their evolution over time. The objectives of the CS study and sub-study are: 1. To identify a systemic taxonomy for patients with SADs by producing the following data in individuals with SADs and controls: genetic, epigenomic, transcriptomic, flow cytometric (from peripheral blood mononuclear cells (PBMCs)), metabolomics and proteomic in plasma and urine, exosome analysis, classical serology (antibodies and autoantibodies), and clinical data. 2. To better characterize individual SADs at the omics level. 3. To perform clustering analyses to determine the groups of individuals who, differentially from other groups, share specific molecular features (precision medicine). 4. A deeper analysis will be done in a substudy of 288 individuals. The clustering process will be data-driven with the aim to find the most homogenous and differentiated clusters of diseases that clearly separate differentiate individuals from controls and other patient clusters. Aims of the Inception cohort: Specifically, this inception cohort aims at: 1. assign individuals newly diagnosed with an systemic autoimmune disease (SAD) to any of the reclassification clusters discovered in the CS study, 2. to study the development and modifications of OMICS signatures/clusters occurring in each individual patient in the course of the disease, including the impact of treatment on their individual pattern, and 3. to perform deep (thorough) OMICs studies to compare their patterns of OMICS as a group, with the patterns obtained in the CS cohort. The inception cohort will have patient follow up and sample collection at baseline, month 6(±1 month) and month 18 (±1 month). As the newly diagnosed patients we plan to recruit will have minimum or no treatment, we will identify differences and similitudes to patients from the cross-sectional study that have undergone long-term treatment.
