About

The purpose of this pilot study is to evaluate the safety, tolerability and potential effectiveness of CONCERTAÂ® (methylphenidate hydrochloride extended-release tablets), a central nervous system (CNS) stimulant for the treatment of adults with Attention Deficit Hyperactivity Disorder (ADHD).

Full description

CONCERTA® is a long-acting form of methylphenidate (a CNS stimulant). Methylphenidate is a recognized first-line treatment for ADHD in children and adolescents. It is widely acknowledged in the scientific literature that the disorder often will persist in adulthood, and is associated with significant morbidity and undesirable outcomes. Despite this, few studies have been conducted to investigate the efficacy and safety of stimulant therapy in treating ADHD in adults. As a consequence, drug treatment options for adult sufferers of ADHD are limited. The primary objective of this pilot, open-label study is to evaluate the safety, tolerability and potential effectiveness of CONCERTA® (18, 36, 54 or 72 mg of methylphenidate hydrochloride, administered once-daily) in adult subjects with Attention Deficit Hyperactivity Disorder (ADHD). Patients cannot have been treated with any methylphenidate- or amphetamine-containing medication within 4 weeks of screening visit. Once deemed eligible, subjects will be started on 18 mg of CONCERTA® once-daily for 3 days, titrated up on Day 4 to 36 mg and maintained at this dose for 7 days. Depending on patient response, the dose of CONCERTA® can continue to be titrated up every 7 days, first to 54 mg and then to a maximum of 72 mg per day, in order to achieve the optimal dose for each patient. The primary efficacy outcomes will be the changes from baseline to the end of treatment in the inattention and hyperactivity/impulsivity subscale scores of the investigator-rated Conners' Adult ADHD Rating Scale (CARRS). Safety and tolerability will be monitored throughout the study. The study hypothesis is that stimulant therapy in treating adult ADHD will be safe and effective, measured by the Conners' Adult ADHD Rating Scale (CAARS) score. CONCERTA® is taken orally, once-daily. Starting with CONCERTA® 18 mg for 3 days, subjects are titrated up on Day 4 to 36 mg for 7 days. Depending on response, tolerability and clinician's discretion, the dose of CONCERTA® can continue to be titrated up every 7 days, first to 54 mg and then to a maximum of 72 mg per day (two 36 mg tablets), until each subject's optimal dose is achieved. The titration period will last a maximum of 24 days.
