Trial summary

Sleep-Wake and behavioral disorders in Smith Magenis Syndrome (SMS) are strongly linked to an inversion of the nychtemeral secretion of melatonin. This inversion have been described in children with SMS. However its evolution during adulthood remains unknown. Read more about this study

About this study

Official title: Characterization of Behavioral Disorders and 24 H-melatonin Level in Adults With Smith Magenis Syndrome

Sleep-Wake and behavioral disorders in Smith Magenis Syndrome (SMS) are strongly linked to an inversion of the nychtemeral secretion of melatonin. This inversion have been described in children with SMS. However its evolution during adulthood remains unknown. The aim of this study is to assess 24hours melatonin levels in 10 adults with SMS in order to optimize medication in adults with SMS

Read the detailed description

SMS is one of the rare syndromes in which the inversion of melatonin secretion is regular, which is an exceptional situation for the study of the influence of genetic factors on the regulation of sleep / wake rhythm. Recently, point mutations of the RAI1 gene (Retinoic Acid Induced 1) have been identified in individuals with the clinical features of SMS with a reversal of the secretion rate of melatonin ,highlighting the role of RAI1 in SMS sleep disorders.

Daytime secretion of melatonin is associated with significant drowsiness and plays a major role in diurnal behavior disorders, especially in younger people. Conversely, the absence of nocturnal melatonin is a causal factor in the shortening and fragmentation of nocturnal sleep .

Basically, little is known about the mechanisms that explain the inversion of the secretion rate of melatonin in SMS.

These aspects, and in particular the nycthemeral reversal of the melatonin cycle, have been described in a population of children and we do not know how these disturbances evolve in adulthood

What is being measured

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

  1. 24h melatonin levels

    Plasmatic melatonin level will be assessed every hour during 24h for each subject

    Measured: 24 hours

Secondary outcomes (1)
  1. Analysis of actimetry

    At the end of the Visit 1 interview, an actimeter will be given to the patient to be worn on the previous two weeks before Visit 2. This will allow the evaluation of the sleep / wake rhythm in the usual life situation. The actimeter will be reported by the patient during the second visit .

    Measured: 15 days

Questions about this trial

What is this clinical trial studying?

A study testing Hourly dosing of the nychtemeral secretion of melatonin in people with Smith Magenis Syndrome, run by Hôpital le Vinatier at 1 site in France.

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 2 inclusion and 6 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 22 Apr 2019. 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 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?

24h melatonin levels (time frame: 24 hours). 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 22 Apr 2019.
