New study aims to speed up FSHD drug development
NCT ID NCT04038138
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is working to create better tools for measuring muscle function in people with facioscapulohumeral muscular dystrophy (FSHD). Researchers will follow 100 adults with FSHD for up to 24 months, testing new ways to track disease progression. The goal is to make future clinical trials more efficient and reliable.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could provide better ways to measure FSHD progression, making future drug trials faster and more reliable.
- What could go wrong
- This is an observational study, not a treatment trial. It focuses on measurement tools, so it won't directly improve patient health. Results may not apply to all FSHD patients.

Not a phased trial
Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Inclusion Criteria * Genetically confirmed FSHD1 or clinical diagnosis of FSHD with characteristic findings on exam and an affected parent or offspring 63 * Age 18-75 years * Symptomatic limb weakness * Patient able to walk alone or with a walking aid. * Manual Muscle Testing (MMT) score ≥ 4 for one of the lower limb muscles * Patient affiliated to the social security system * Patient giving written consent after written and oral information. * If taking over the counter supplements willing to remain consistent with supplement regimen throughout the course of the study Exclusion Criteria * Cardiac or respiratory dysfunction (deemed clinically unstable, or would interfere with safe testing in the opinion of the Investigator) * Orthopedic conditions that preclude safe testing of muscle function * Regular use of available muscle anabolic/catabolic agents such as corticosteroids, oral testosterone or derivatives, or oral beta agonists * Use of an experimental drug in an FSHD clinical trial within the past 30 days * Pregnancy. * Contraindication for muscle MRI * Any major comorbidity
