About this study

The main objective of the study is to investigate the determinants of the quality of life in children and adults with Neurofibromatosis type 1 (NF1) and more particularly the specific impact of neuropsychological deficits. In fact, cognitive impairment is currently considered as one of the most pervasive features of this genetic disorder but its relationship with the worsening of quality of life found in this population has not been directly investigated to date.

Secondary objectives of this study are (i) to compare neuropsychological and quality of life measures between patients and healthy controls matched by age, gender and education level, (ii) to contrast neuropsychological deficits incidence between patients and controls, and (iii) to differentiate NF1 children's self versus hetero-assessment of quality of life.

The main hypothesis of this study is that the neuropsychological impairment classically identified in this clinical population will be associated to the quality of life's worsening both in children and adults.

Read the detailed description

The study cohort will consist of 150 patients with NF1 (100 adults and 50 children) recruited from the Neurofibromatosis Clinic at the University Hospital in Nantes and Créteil (France). A sample of 150 healthy controls (100 adults and 50 children) will also be recruited from sport and leisure clubs to serve as a normally developing control group.

The protocol assessment includes a standard and thorough neuropsychological examination specific to children and adults, to investigate the different aspects of cognitive domains: language, visuoperceptive and visuomotor abilities, memory, attention, executive function and intelligence skills. Quality of life is measured by a questionnaire specifically adapted to children and adults.

Other factors linked to the NF1 disease (familial or sporadic form, severity and visibility) and to demographic characteristics (sex, age, education level) will be taken into account to study their respective impact on quality of life, as compared with neuropsychological measures.

What is being measured

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

  1. Quality of life as measured by the questionnaires used in children and adults

    Several domains in relation with quality of life (self perception, well-being, social life, emotions, etc.)

    Measured: at day 0 for adults; at 4 weeks for children

Secondary outcomes (1)
  1. Scores obtained from neuropsychological tests (composite measure)

    The neuropsychological tests used in this study evaluate different domains: language, visuoperceptive and visuomotor abilities, memory, attention, executive function and intelligence skills.

    Measured: at day 0 and 2 weeks for adults; at day 0, 2 weeks and 4 weeks for children

Questions about this trial

What is this clinical trial studying?

A study testing Neuropsychological examination and quality of life measures in people with Neurofibromatosis Type 1, run by Nantes University Hospital at 2 sites 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 10 inclusion and 5 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 6 Jul 2016. 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 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?

Quality of life as measured by the questionnaires used in children and adults (time frame: at day 0 for adults; at 4 weeks for children). 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 6 Jul 2016.
