About this study
Official title: A Multicentre, Randomised, Double-Blind, Placebo-Controlled, Parallel Group, Dose-Response Study To Evaluate the Safety And Efficacy Of Prolonged Release OROS Methylphenidate Hydrochloride (18, 36 and 72 mg/Day), With Open-Label Extension, In Adults With Attention Deficit/Hyperactivity Disorder
The purpose of this study is to evaluate the effectiveness and safety of three doses of prolonged-release methylphenidate (a central nervous system (CNS) stimulant) in adult patients with attention deficit/hyperactivity disorder (ADHD).
Read the detailed description
Stimulant therapy is the mainstay of pharmacologic treatment for attention deficit/hyperactivity disorder (ADHD) in children and adolescents. Methylphenidate is the most commonly prescribed and most frequently studied stimulant medication for children and adolescents with this disorder. It is widely acknowledged in the scientific literature that ADHD often will persist into adulthood. Few large-scale, rigorous studies have been conducted to investigate the effectiveness and safety of stimulant therapy in treating ADHD in adults. This is a multicentre, double-blind, randomised, placebo-controlled, parallel group, dose-response study comparing three doses of prolonged-release methylphenidate (18, 36, and 72 mg once-daily) versus placebo in adult patients with ADHD. The primary efficacy outcome will be the change from baseline to the end of the double-blind phase in the sum of the inattention and hyperactivity/impulsivity subscale scores of the investigator-rated Conners' Adult ADHD Rating Scale (CAARS). Additional measures of effectiveness will include the following scales: CAARS-self report, to rate items pertaining to the patient's behavior/problems; Clinical Global Impression (CGI), to rate the severity of a patient's illness; Sheehan's Disability Scale (SDS), to measure the extent to which a patient's work, social life or leisure activities and home life or family responsibilities are impaired by his/her symptoms; Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q); and the Global Assessment of Effectiveness. Safety and tolerability will be monitored throughout the study. The study hypothesis is that prolonged-release methylphenidate taken once-daily will produce clinically significant improvements compared with placebo on measures of inattention and hyperactivity/impulsivity of the Conners' Adult ADHD Rating Scale in patients with adult ADHD. Prolonged-release methylphenidate 18, 36 or 72 mg oral capsules, or placebo, taken once-daily for 5 weeks. Eligible patients may continue prolonged-release methylphenidate in an open-label extension study for an additional 7 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing methylphenidate hydrochloride in people with Attention Deficit Disorder With Hyperactivity, run by Janssen Pharmaceutica N.V., Belgium.
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 2 inclusion and 6 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 17 May 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?
Change from baseline in the sum of the inattention and hyperactivity/impulsivity subscale scores of the investigator-rated Conners' Adult ADHD Rating Scale at the end of the double-blind phase (5 weeks) compared with placebo.. 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 NCT00246220, which also lists 2 linked publications.
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 17 May 2011.
