Molecular Diagnosis of Systemic Autoinflammatory Diseases (SAIDiag)

March 4, 2026 updated by: Institut National de la Santé Et de la Recherche Médicale, France
Systemic autoinflammatory diseases (SAIDs) are a set of rare clinically and genetically heterogeneous conditions. The project proposes to identify novel genes and specific signatures in subgroups of patients with SAIDs.

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.

Detailed Description

SAIDs are characterized by long dormant periods with no or only minor clinical symptoms interrupted by febrile crises accompanied by serous and synovial membrane inflammation that spontaneously resolves. Over the last decades, more than 50 genes encoding key components of the innate immune system have been identified to be involved in the pathophysiology of SAIDs, with both germline and somatic mosaic variations. When disease-causing variations are identified, specific biotherapies are proposed depending on the involved gene and pathway. However, despite these scientific advances, most SAIDs (70%) are of unknown etiology, the diagnosis is made with significant delay, and no targeted therapy can be suggested. This project aims to generate specific understanding and develop strategies for SAID patients with unknown etiology. The investigators aim to advance our understanding of SAIDs pathophysiology, find the disease-causing gene variations and identify the involved cellular pathways that should accelerate correct diagnosis and personalize treatment.

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.

Ages Eligible for Study

1 week to 120 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Probability Sample

Study Population

Participants in this research will be recruited during a follow-up consultation for their condition.

Description

Inclusion Criteria:

  • A patient presenting with a clinical and biological aseptic inflammatory syndrome associating one or more of the following signs: spontaneously resolving fever, abdominal (pain, diarrhea), locomotor (arthralgia, myalgia), thoracic (pain, pericarditis), cutaneous, sensory (uveitis, deafness), or renal (amyloidosis) involvement.

Exclusion Criteria:

  • Adult subject to legal protection measures (guardianship, curatorship, safeguard of justice).

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
To identify SAIDs disease-causing mutations and genes and to explore specific biological signatures.
Time Frame: Anytime in the period of 10 years
Molecular studies will be performed through the use of a SAID next generation sequencing (NGS) gene panel, followed by whole exome/genome sequencing (WES/WGS) in patients with no obvious genetic abnormality identified by the gene panel. When possible trio studies (the patient and his parents) will be performed in order to facilitate the interpretation of the molecular variants. Transcriptomics and cytokines profiles will be performed on whole blood cells to identify weakly expressed genes/proteins and by single cell experiments in order to assess cell-specific expression. These data will permit to better shape functional studies and to explore specific biological signatures.
Anytime in the period of 10 years
To identify novel and better assess the disease pathways
Time Frame: Anytime in the period of 10 years
Functional studies will be performed to evaluate the pathogenicity of the identified molecular variants, to assess the involvement of new candidate genes in SAIDs, to characterize the molecular networks to which the corresponding proteins belong and to open up new therapeutic avenues.
Anytime in the period of 10 years

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
To propose personalized treatment options
Time Frame: Anytime in the period of 10 years
Depending on the disease gene identified and on the involved signalling pathway, specific biotherapies could be proposed to SAID patients.
Anytime in the period of 10 years

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 18, 2022

Primary Completion (Estimated)

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.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
