About this study

Official title: Comportemental and Neuropsychologic Study of Children With Neurofibromatosis Type 1 Treated by Methylphenidate. A Double-blind Randomised Study Methylphenidate Versus Placebo

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder with an estimated prevalence of 1/2190 to 1/6711. Attention deficit hyperactivity disorder (ADHD) has been reported to be common in NF1. We, the researchers at Hospices Civils de Lyon, designed a randomized, double blind, placebo controlled, crossover trial with a total follow-up duration of 9 weeks to evaluate the effect of methylphenidate (MPH) on the improvement on the simplified parents Conners' Rating Scale. In a parallel exploratory study we will compare the nature of attention deficit disorders in NF1 children to 30 ADHD NF1-free controls. Children aged 7 to 12 years are eligible when their intelligence quotient (IQ) is between 80 and 120. Fifty subjects (25 for each period) were required for testing the primary study hypothesis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

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

  1. Effect of methylphenidate compared to placebo on ADHD. Time of measurements are realised on day 0, day 28, day 63 + 2 days.

Secondary outcomes (3)
  1. To evaluate the efficacy of methylphenidate compared to placebo on specific neuropsychologic, depression and anxiety scales

  2. To compare the nature of attention deficit disorders in NF1 children with those with primary ADHD, depression, and anxiety using the State Trait Anxiety Inventory for Children (STAI-C) and the Children's Depression Inventory (CDI).

  3. Time of measurements are realised on day 0, day 28, day 63 + 2 days.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing methylphenidate in people with Neurofibromatosis Type 1, run by Hospices Civils de Lyon 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 6 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 27 Jan 2011. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Effect of methylphenidate compared to placebo on ADHD. Time of measurements are realised on day 0, day 28, day 63 + 2 days.. 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 NCT00169611, which also lists 1 linked publication.

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 27 Jan 2011.
