What this trial studies

This observational study aims to characterize the disease course and clinical features of children diagnosed with LAMA2-related dystrophies, specifically focusing on Merosin Deficient Congenital Muscular Dystrophy. Over a two-year period, participants will undergo comprehensive assessments including muscular and respiratory function, cognitive abilities, quality of life, growth parameters, and biomarker evaluations. The study seeks to establish a well-defined cohort of patients in France for future clinical trials and to validate various outcome measures relevant to the disease. By collecting prospective data, the study aims to reduce bias and variability in results compared to retrospective studies.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 6 years and older with a confirmed diagnosis of LAMA2-related dystrophies.

Not a fit: Patients with developmental quotients less than 70 or those with behavioral disorders requiring general anesthesia for MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the natural progression of LAMA2-related dystrophies, aiding in the development of targeted therapies.

How similar studies have performed: While this study builds on the need for natural history data in LAMA2-related dystrophies, it is part of a broader effort that has seen success in similar observational studies.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Signed informed consent by the Legal Authority Responsible and/or assent by the subject (starting from 6 years old)
* Subject must be
* Supportive clinical phenotype and diagnosis of LAMA2-RD, confirmed by:

  * Two pathogenic variants in the LAMA2 gene (via a diagnostic laboratory included on an approved list of genetic testing laboratories (Annex 1)) or
  * Muscle biopsy with absence of merosin (laminin-211) and at least one pathogenic variant in the LAMA2 gene
* Absence of another confirmed neurological genetic disease
* Willingness to maintain current exercise and/or physical therapy regimen for the duration of the clinical study
* Willingness to comply with the study protocol, including all the mandatory study procedures and visits
* Affiliated to or a beneficiary of a French or acknowledged in France, social security scheme

Exclusion Criteria:

* Developmental quotient less than 70 and/or behavioral disorder requiring general anesthesia to perform an MRI
* Acute medical illness or hospitalization within 30 days prior to informed consent
* Participation in a previous trial of any investigational agent for LAMA2-RD, or use of any other investigational therapy within 30 days prior to informed consent, or participation in other clinical studies, within 30 days (or 5 half-lives, whichever is longer) prior to informed consent, which, in the opinion of the PI, may potentially confound results from this study
* Other significant medical condition and/or overall fragility of medical status, which in the opinion of the Investigator may confound interpretation of the clinical course of LAMA2-RD
* Pregnant or breastfeeding women
