About this study
Official title: LAMA2 Retrospective Review of Medical Charts in Infants & Toddlers With LAMA2-Congenital Muscular Dystrophy
This retrospective chart review study of 75-120 LAMA2-CMD patients will expand the investigators understanding of the natural history of this disease. Current and pending publications cover research performed only in ages 5-16 years; there is currently no documented natural history for patients ages 0-5 years. Data collected in this study has the potential to inform the design of future interventional studies that draw nearer to clinical trial readiness every day.
Read the detailed description
LAMA2-related congenital muscular dystrophy (LAMA2-CMD) is caused by a deficiency of the α2 subunit of laminin due to mutation of the LAMA2 gene.
Typical LAMA2-CMD cases present with prominent hypotonia and weakness in infancy. Congenital contractures are a common finding in the hands and feet. Weakness and contractures are slowly progressive, and most patients do not achieve independent ambulation. Facial weakness and jaw contractures disrupt normal feeding, resulting in failure to thrive. Most patients require nutrition support at an early age. Cardiac involvement is rare. In addition to neuromuscular aspects of the disorder, patients with LAMA2-CMD have central nervous system findings including prominent T2 and fluid-attenuated inversion recovery (FLAIR) abnormalities in the white matter on brain MRI. Despite the prominent changes on MRI, cognitive function is normal, although patients are at risk of seizures, which are seen in 30% of patients.
A number of potential therapies are currently in development for LAMA2-CMD. A larger prospective natural history was conducted at the National Institutes of Health in LAMA2-CMD patients, ages 5-16 years of age, testing and validating a wide variety of outcome measures suitable for use in clinical trials. However, appropriate clinical outcome measures in younger patients (ages 0-5 years) have yet to be validated.
Some treatments currently in development will almost certainly be more effective the earlier the treatment is administered. Given that there is a distinct lack of data for affected individuals less than 6 years of age, this study will be instrumental in building outcome measures appropriate in younger patients. In order to obtain regulatory authorization to launch clinical trials in affected individuals less than 6 years of age, a documented natural history for this age group must be demonstrated.
The primary objective of this study is to characterize aspects of LAMA2-CMD in ages 0-5 years through medical chart review/data extraction, and participant survey. This study aims to derive clinical trial endpoints useful in conducting interventional trials in the near future.
The secondary objectives of this study include identifying potential prognostic variables of LAMA2-CMD, identifying adverse events associated with LAMA2-CMD that warrant monitoring and potential preventative measures, and to grow the knowledge base of care standards and optimization to improve the patient's quality of life.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This retrospective chart review study of 75-120 LAMA2-CMD patients will expand the investigators understanding of the natural history of this disease. Current and pending publications cover research performed only in ages 5-16 years; there is currently no documented natural history for patients ages 0-5 years. Data collected in this study has the potential to inform the design of future interventional studies that draw nearer to clinical trial readiness every day.

Questions about this trial
What is this clinical trial studying?
An observational study of Merosin Deficient Congenital Muscular Dystrophy, run by Prothelia, Inc. at 1 site in United States.
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 9 inclusion and 4 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 7 Feb 2022. 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 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?
To characterize the natural history of LAMA2-CMD (time frame: Birth to 5 years of age). 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 NCT04299321, 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 Feb 2022.
