Key requirements

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 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Inclusion criteria will be limited to those over 18 years of age, with a genetic confirmation of DM1 who are able to provide informed consent. This unrestrictive approach will enable assessment of a true cross-section of the population, including those with congenital, childhood and adult onset. Two substudies will be open to a subset of patients, one assessing muscle through MRI and on focussing on sleep and fatigue. Additional restrictions may be in place to ensure the safety of the participants during these studies. Informed consent will be obtained from all patients, including detailed patient information. Sharing and storage of data and samples will be discussed in this information and covered appropriately in the consent.

Who may be able to join

  • Main Inclusion Criteria
  • 18 years of age or over
  • Genetic confirmation of Myotonic Dystrophy Type 1
  • Able to consent and willing to participate throughout the duration of the study.
  • Additional Inclusion Criteria for MRI study:
  • Aged between 18 and 55 years

  • Ambulant or ambulant-assisted
  • Additional Inclusion Criteria for sleep study:
  • 1. Aged between 18 and 55 years

Who cannot join

  • Main Exclusion Criteria

About this study

Official title: Myotonic Dystrophy Type 1 (DM1) Deep Phenotyping to Improve Delivery of Personalized Medicine and Assist in the Planning, Design and Recruitment of Clinical Trials

PhenoDM1 will use patient reported outcomes to assess levels of pain, fatigue and quality of life in this cohort. Clinical and functional outcomes will look at muscle wasting and levels of myotonia. DNA, RNA, serum and CSF samples will be taken from all patients so that additional genetic and molecular biomarker analysis can be carried out. A subset of patients will undergo detailed sleep studies along with skeletal muscle MRI of the lower limbs. This study will complement the work of other groups currently looking at myotonic dystrophy type 1 using the same outcomes and measures where possible.

Read the detailed description

Myotonic Dystrophy type I (DM1) is the most common form of adult muscular dystrophy, affecting 1 in 8000 individuals. It is an autosomal dominant disorder with multisystemic involvement of multiple organs and tissues, namely brain, heart, endocrine system, eyes and both smooth and skeletal muscles. It results from the CTG expansion of an untranslated region 3' terminal of the DMPK gene which causes a disturbance of the RNA metabolism, in particular defective splicing of various pre-mRNAs such as the muscular chloride channel (causing myotonia), the insulin receptor (causing diabetes) and others. We will carry out an in-depth characterisation of 400 adult DM1 patients identified from local clinical populations across England and through the national DM Registry. Over a two year period we will take measurements 12 months apart to address specific symptoms that cause major quality of life impairment including muscle weakness, myotonia, excessive daytime sleepiness and cognitive impairment. DNA samples will be collected in order to determine the CTG repeat length and serum samples for biomarker identification. We will carry out muscle MRI and sleep studies in a subset of 50 patients. The implemented measures will capitalise on the efforts of previous cohort studies ensuring that all measures are comparable with existing datasets.

Questions about this trial

What is this clinical trial studying?

An observational study of Myotonic Dystrophy Type 1, run by Newcastle-upon-Tyne Hospitals NHS Trust at 2 sites in United Kingdom.

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 10 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 13 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. 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?

Strength and function (time frame: 9-12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Apr 2021.
