About this study

Official title: Long-term Safety and Effectiveness of OROS (Methylphenidate HCl) in Children With ADHD

The purpose of this study is to evaluate the long-term safety and effectiveness of OROS® Methylphenidate HCl (a central nervous system stimulant) in children with attention deficit hyperactivity disorder (ADHD).

Read the detailed description

Attention Deficit Hyperactivity Disorder (ADHD) represents the most common neurobehavioral disorder in children, affecting 3% to 5% of the school-age population. Behavioral pediatricians, child psychiatrists, and child neurologists indicate that referrals for ADHD may constitute up to 50% of their practices. This is a multicenter, open-label, non-randomized, single-treatment study in children 6 to 13 years of age with ADHD who have successfully completed specific earlier ALZA studies. Part I of this study will evaluate the safety and effectiveness of OROS® (methylphenidate HCl) for a period of one year in children with ADHD. Part II of this study continues the evaluation of the safety and effectiveness of OROS® (methylphenidate HCl) in children with ADHD who have completed one year in Part I of the study. During Part I of the study, patients will be assigned to treatment with OROS® (methylphenidate HCl) 18, 36, or 54 milligrams once daily, as determined by the results from their participation in earlier ALZA studies. Patients continuing in Part II of the study continue to receive a daily dose as determined from the dosing at the end of Part I. Doses can be titrated up or down, as considered appropriate by the medical personnel at the study site, with a maximum once-daily dose of 54 milligrams. Effectiveness is determined by standardized measurements of attention, behavior, and hyperactivity including: the IOWA (Inattention Overactivity with Aggression) Conners Rating Scale, Inattention/Overactivity (I/O) and Oppositional/Defiance (O/D) subscales; Peer Interaction assessment; Global evaluation of effectiveness of therapy; and the Parent Satisfaction Questionnaire. Safety evaluations include the incidence of adverse events, physical examinations, clinical laboratory tests, vital signs, sleep quality, appetite, and the presence/severity of tics (hard-to-control, repeated twitching of any parts of the body or hard-to-control repeating of sounds or words).

Data will be summarized and no formal hypotheses will be tested. Part I: A daily morning oral dose of 18, 36, or 54 milligrams of OROS® (methylphenidate HCl) for up to 12 months. Part II: Continuation for up to 15 months of the same daily dose taken at the end of Part I. Total treatment duration to approximately 27 months.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing methylphenidate HCl in people with Attention Deficit Hyperactivity Disorder, run by Alza Corporation, DE, USA.

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 5 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 14 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Incidence of adverse events; Changes in physical examinations, clinical laboratory tests, vital signs, sleep quality, appetite, and tics. 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 NCT00269815, 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 14 Jun 2011.
