Outcome Measures in Duchenne Muscular Dystrophy: A Natural History Study
An observational study of Duchenne Muscular Dystrophy, run by University College, London at 5 sites in 3 countries.
Trial summary
Novel emerging therapies for Duchenne Muscular Dystrophy (DMD) require a deeper understanding of DMD natural history. This study aim to assess the natural history of DMD through a composite assessment tool capable of capturing disease progression linking ambulant and non-ambulant phases of the disease.

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 5 to 18 years
- Men only
- Healthy volunteers accepted
- Child, Adult
Study population: Patients with Duchenne muscular dystrophy (DMD) recruited across 5 specialised neuromuscular centres (London, Newcastle, Paris, Leiden, Nijmegen)
Who may be able to join
- For non-ambulant patients:
- Children and teenagers aged between 5 and 18 years with DMD, who have lost the ability to walk 10 meters with no support
- The diagnosis of DMD must be documented by genetic testing. If a muscle biopsy is available, it should contain less than 10% of revertant fibres

- Patients should be capable of sitting upright in a wheelchair for at least an hour
- Patients should be stable from a respiratory point of view. Artificial ventilation with either Bipap or tracheostomy is not a contraindication to the study.

- Informed consent signed by a parent/legal guardian (or by the patient if 16 years of age).
- In France, a subject will be eligible for inclusion in this study only if either affiliated to, or a beneficiary of, a social security category.
- For ambulant patients:
- Ambulant children from 5 years old and teenagers with DMD, and potential candidates for future genetic therapies with antisense oligomer (AO) exon skipping
- The diagnosis of DMD must be documented by MLPA or a standard genetic test for the disorder, genotypically confirmed to have an out-of-frame deletion(s) that could be corrected by skipping exon 51 or 53 or 45 or 44 or 46 or 50 or 52
- If a muscle biopsy is available less than 10% revertant fibres
- Ability to walk independently for at least 75 meters in 6 minutes at recruitment.

Who cannot join
- For non-ambulant patients:

Official title: Developing Tools for Assessing the Natural History of Ambulant and Non-ambulant DMD Individuals to Assist in Antisense-oligomer Clinical Trials

Read the detailed description
Novel emerging therapies for Duchenne Muscular Dystrophy (DMD) require a deeper understanding of DMD natural history. This study aim to assess the natural history of DMD through a composite assessment tool capable of capturing disease progression linking ambulant and non-ambulant phases of the disease.
With a recruitment target of 80 DMD patients across 5 centres (London, Newcastle, Paris, Leiden, Nijmegen), subjects are assessed 6 monthly according to a shared protocol. Assessments include 6-minute walk distance (6MWD), North Star Ambulatory Assessment (NSAA), Performance of Upper Limb (PUL) and MyoSet (myogrip, myopinch and moviplate). Both ambulant and non-ambulant subjects undergo upper limb evaluation and respiratory function test including forced vital capacity (FVC), maximum inspiratory and expiratory pressures (MIP/MEP). A subgroup of patients performs annual whole body DEXA scan. An imaging sub-study will aim to characterize muscle (upper/lower limb) and brain MRI.
The investigators will analyze the longitudinal data for the different assessment tools and explore correlations among them.
This study will offer a comprehensive natural history of DMD including novel outcome measures, allowing to capture disease progression and explore the relationship between different assessment tools.

Questions about this trial
What is this clinical trial studying?
An observational study of Duchenne Muscular Dystrophy, run by University College, London at 5 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 21 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Netherlands, United Kingdom, France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease progression (time frame: up to 4 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02780492, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2024.
