Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for people with rare systemic autoimmune diseases, such as lupus, scleroderma or myositis. People with unusual signs of these diseases can also join. Blood samples are collected for research.
- Age
- From 6 Years to 99 Years
- Sex
- All sexes can join.
- Disease stage
- Rare systemic autoimmune disease (lupus, scleroderma, myositis for example), or an atypical presentation of a documented or probable systemic autoimmune disease.
- Earlier treatment
- People who are receiving, or are likely to receive, new innovative therapies (a new molecule on the market, gene therapy, cell therapy, etc.) can join.
Main reasons for not taking part
- Known anemia with hemoglobin below 10 g / dl
- Patients under protective supervision (guardianship, curators)
- Pregnant or breastfeeding women

About the trial
What the trial wants to find out
The aim of this project is to start a biological and clinical collection of patients presenting systemic autoimmune disease. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies
The group in the trial
- patients suffering from autoimmune disease
Biological samples will be collected in the normal diagnosis and follow-up process. Only blood will be taken in larger quantity.
Treatment: Blood sampling
Questions to ask the study team
- How often do I need to come in, and for how long each time?
- Are travel costs paid?
- Can I keep my own doctor?
- What happens if I want to stop?
