Who may be able to join

  • The study will include 20 boys aged 8 to 10 years old, regularly enrolled in local schools and directed to the research through advertisement in the media, contact with schools or directly referred to the Attention Deficit/Hyperactivity Program (ProDAH/HCPA) by primary care services for assessment and treatment.

About this study

Official title: COST-EFFECTIVENESS STUDY OF THE TREATMENT OF ATTENTION DEFICIT/HYPERACTIVITY DISORDER IN BRAZIL

This study is an open-label, 6 month trial, of immediate release methylphenidate (MPH-IR) for children with ADHD aimed at assessing whether the observable behavioral changes seen during treatment are associated with potentially more stable underlying modifications in brain functioning (resting-state functional connectivity). Additionally, we will also be looking at treatment effects on neuropsychological processes and reading skills. This information will contribute to the first Brazilian study assessing the cost-effectiveness of the treatment of ADHD. Children with ADHD will be compared to a sample of sex and age-matched sample of typically developing children.

What participants receive

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

  • methylphenidate (Ritalin®)Drug

    The scheme provides for initial dose of 0.3 mg / kg / day, with an average dose of 1mg/kg/day. The increases will be made considering the presentation of the drug (10mg), which allows increments of 5mg or 10mg, which will be made in clinical review, as the clinical symptoms, including increasing the dose until there is more room for improvement or there is presence of significant adverse effects, all the patients with indication of treatment will be assessed before the use of medication, 15 days, 30 days, 3 and 6 months after the start,

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing methylphenidate (Ritalin®) in people with Attention-deficit/Hyperactivity Disorder, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.

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 1 inclusion and 1 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 21 Jul 2014. 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 Brazil. 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?

Resting-state functional connectivity (time frame: After 6 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 21 Jul 2014.
