Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with a suspicion of myositis, including various subtypes such as dermatomyositis and polymyositis.
✕Probably not a fit
Patients under legal protection or those who oppose the use of their data will not benefit from this study.

What this trial studies
This observational study aims to create a cohort of patients with inflammatory myopathies to better understand the disease's underlying mechanisms and identify potential treatments. It will involve collecting a wide range of clinical, radiological, and biological data, including muscle biopsies and blood samples, to establish a biobank. Patients will undergo regular follow-up visits to assess muscle strength, function, and other relevant health metrics. The goal is to delineate factors contributing to myositis and improve prognostication based on various clinical variables.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and treatment options for patients with inflammatory myopathies.
How similar studies have gone: While myositis is a rare condition, similar cohort studies have shown promise in understanding autoimmune diseases, suggesting potential for success in this approach.
