About this study

Official title: A LAMA2-related Muscular Dystrophy Study: Brain Magnetic Resonance Imaging (MRI)and Brain Electrophysiology Evaluation

Laminin alpha-2 (LAMA2)-related muscular dystrophy (LAMA2-MD, Merosin Deficient CMD) is a form of congenital muscular dystrophy (CMD). A person with LAMA2-MD will have changes on brain imaging (MRI), a decrease or absence of the protein merosin (laminin 211) on muscle or skin biopsy and changes in the LAMA2 gene that are inherited from both parents. Several studies have described the changes on brain MRI. Brain changes on MRI do not correlate with the partial reduction or absence of merosin on muscle or skin biopsy. 8-30% of people with LAMA2-MD develop seizures. The types of seizures, electroencephalogram changes and common treatment regimens have not been characterized. This study will review the magnetic resonance imaging (MRI) changes, determine whether certain brain MRI changes are linked to seizures and define the common seizure treatment regimens.

Read the detailed description

LAMA2-MD is a congenital muscular dystrophy (CMD) subtype caused by mutations in the laminin alpha 2 gene. LAMA2-MD may present clinically as an early onset, severe phenotype or a late onset limb girdle phenotype. The early onset form is most commonly associated with a complete absence of merosin on muscle biopsy with profound neonatal hypotonia, possible respiratory distress and feeding difficulties while the late onset form presents with proximal muscle weakness, contractures and is able to achieve walking. In both early and late onset forms, brain white matter abnormalities have been described on brain MRI and approximately 8-30% develop a seizure disorder. On magnetic resonance (MR) spectroscopy, white matter changes are shown to be due to increased water content rather than areas of demyelination. Both, non-ambulant and ambulant patients may develop respiratory insufficiency requiring non-invasive ventilation and scoliosis.

Although several studies have evaluated the correlation between brain MRI white matter changes and cognition, no studies to date have provided a systematic evaluation of brain imaging, electrophysiologic testing and seizures in patients identified by molecular or immunohistochemical testing to have LAMA2-MD.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Identify and grade the structural brain abnormalities observed on MRI

    Both single and longitudinal brain MRIs will be retrieved with patient consent from hospitals within the United States. Two trained neuroradiologists will evaluate de-identified brain MRIs using a pre-determined scoring system to identify and classify structural abnormalities.

    Measured: up to 5 months

Secondary outcomes (3)

  1. Seizure History

    To obtain a seizure history on all individuals with LAMA2-MD who have had a seizure, including: type of seizures, age of seizure onset, seizure frequency, need for mechanical ventilation, seizure medications, and need for emergency room (ER) visit or hospitalization.

    Measured: up to 8 months

  2. Evaluation of baseline and diagnostic electroencephalograms

    Both baseline and diagnostic electroencephalograms (EEG) will be obtained with patient consent from hospitals within the United States. An epileptologist will review de-identified EEG recordings to identify and classify abnormalities using a predetermined scoring system.

    Measured: up to 8 months

  3. Examine the association between brain MRI structural abnormalities and EEG findings

    Compare the frequency of various grades of brain MRI abnormalities in individuals with LAMA2-MD with and without seizures. Identify any association between MRI abnormality and type of seizure.

    Measured: up to 11 months

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 5 inclusion and 1 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: withdrawn, as of the sponsor's last update on 7 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 was withdrawn before enrolling participants, so there are no results.

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?

Identify and grade the structural brain abnormalities observed on MRI (time frame: up to 5 months). 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 NCT01952028, which also lists 10 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 7 Mar 2018; AzTrials last refreshed its copy on 27 Oct 2026.
