About this study
Official title: Screening, Efficacy, and Safety Study Evaluating OROS (Methylphenidate HCl), Ritalin and Placebo in Children With ADHD
The purpose of this study is to provide data on the effectiveness of the OROS Methylphenidate Hydrochloride (HCl) formulation compared to placebo and standard immediate-release Ritalin with respect to improving attention and behavior, and decreasing hyperactivity in children with Attention Deficit Hyperactivity Disorder (ADHD). Both OROS Methylphenidate HCl and Ritalin contain the central nervous system stimulant, methylphenidate HCl. The safety associated with the two methylphenidate formulations will also be compared with placebo.
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 double-blind, double-dummy, randomized, placebo-controlled, active-controlled, 3-treatment, 3-period crossover trial to compare the safety and effectiveness (onset of effect, time to loss of effect and overall efficacy) of OROS Methylphenidate Hydrochloride (HCl), with standard immediate-release Ritalin and placebo. During this study, patients receive each of the three treatments (OROS Methylphenidate HCl 18, 36 or 54 milligrams per day, Ritalin 5, 10 or 15 milligrams three times per day, or placebo) for 7 days, and are assigned to one of three dosage levels depending upon their prestudy methylphenidate dose and regimen. The total study participation for each patient will be 21 days. Since ADHD is manifested in a variety of settings and can affect attention and behavior, this study assesses efficacy in home, community school, and laboratory school settings using numerous assessments designed to evaluate various aspects of the disorder. These assessments are completed by a variety of raters, including the parents/caregivers, community school teachers, and laboratory school teachers. The primary measure of effectiveness is the community school teacher's rating on the IOWA Conners Inattention/Overactivity subscale. Additional measures of effectiveness include the IOWA Conners (Inattention/Overactivity and Oppositional/Defiance subscale) ratings, SKAMP attention and deportment ratings, peer interaction and other behavioral ratings, global assessments, SNAP-IV ratings, activity levels during structured activities, accuracy and productivity of independent assigned academic seatwork, and a home situation questionnaire. Safety evaluations include the incidence of adverse events, physical examinations, clinical laboratory tests, vital signs, sleep quality, actigraphy (sleep latency, duration, and arousals), 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). Patients will be given oral doses of: OROS (methylphenidate HCl) 1, 2, or 3 of the 18-milligram tablets once daily, or Ritalin 5, 10, or 15 mg (encapsulated/single capsule) three times a day, or placebo. There are three treatment groups, each group dosing for 7 days for a total of 21 days on study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing OROS (methylphenidate HCl) and Ritalin (methylphenidate) 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 11 Jul 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?
IOWA Conners Inattention/Overactivity subscale ratings by the Community School Teacher (time frame: Up to Day 6 of each treatment period for a total of approximatly 18 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 NCT00269776, 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 11 Jul 2011; AzTrials last refreshed its copy on 6 Nov 2026.
