miR-1 as a blood biomarker for muscular dystrophies and congenital myopathies

Evaluation of the Role of miR-1 in the Pathogenesis and as a Biomarker in Muscular Dystrophies and Congenital Myopathies

Not applicable Interventional University Hospital, Clermont-Ferrand · NCT07415837

This project will see if levels of a blood molecule called miR-1 can track disease status in people with Duchenne/Becker muscular dystrophy, myotonic dystrophy type 1, congenital myopathies, and in healthy volunteers.

What this trial studies

The study measures miR-1 levels in blood samples from four groups: Duchenne/Becker muscular dystrophy, myotonic dystrophy type 1, congenital myopathies, and healthy volunteers, across ages and disease severities. Investigators will compare miR-1 concentrations between groups and correlate levels with clinical severity measures. Participants provide blood samples at the CHU de Clermont-Ferrand and data are analyzed to determine whether miR-1 reliably reflects muscle disease activity. The protocol excludes recent intense exercise and treatments that could alter systemic, muscular, or cardiac biology to reduce confounding.

Who should consider this trial

Good fit: Ideal candidates are people older than 2 years with a confirmed diagnosis of Duchenne or Becker muscular dystrophy, myotonic dystrophy type 1, or a congenital myopathy, as well as healthy volunteers who are affiliated with the French social security system and provide consent.

Not a fit: Patients currently on systemic, muscular, or cardiac treatments that affect biological measurements, those who recently did intense exercise, or people without the eligible diagnoses are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this could give patients and clinicians a simple blood test to monitor disease progression and treatment response.

How similar studies have performed: Prior research has reported abnormal miR-1 levels in various neuromuscular diseases, providing supportive but not yet definitive evidence that miR-1 can serve as a clinical biomarker.

Inclusion Criteria:

* Age: Participants must be older than 2 years of age
* Consent: Participants (or their legal guardians) must provide free and informed consent,. For children, the consent is oral for those under 6 years old and written for those over 6,.
* Social Security: Every participant must be affiliated with the French social security system.

Exclusion Criteria:

* Refusal to participate expressed by the subject or their parental authority.
* Engaging in intense and unusual physical effort within 10 days before the blood draw.
* Current use of any treatment with systemic, muscular, or cardiac effects that could interfere with the study's biological results.
* Subjects or their legal guardians who are under tutelage, curatorship, deprived of liberty, or under judicial protection.
* Women who are pregnant or breastfeeding.
* The presence of an additional pathology that, in the judgment of the clinician, could interfere with the biological findings
