Source: ADHD News From Medical News Today [2009.10.31]
Shire plc (LSE: SHP, Nasdaq: SHPGY), the global specialty biopharmaceutical company, announced findings at a major medical meeting from a Phase IIIb study of the tolerability and effectiveness of Daytrana® (methylphenidate transdermal system) in adolescents aged 13 to 17 years diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). In addition, data regarding the pharmacokinetic profile of Daytrana in children and adolescents was also presented.

Published Studies Related to Ritalin LA (Methylphenidate)
Stimulant treatment reduces lapses in attention among children with ADHD: the effects of methylphenidate on intra-individual response time distributions. [2009.08]
Recent research has suggested that intra-individual variability in reaction time (RT) distributions of children with ADHD is characterized by a particularly large rightward skew that may reflect lapses in attention. The purpose of the study was to provide the first randomized, placebo-controlled test of the effects of the stimulant methylphenidate (MPH) on this tail and other RT distribution characteristics...
Side effects of methylphenidate in childhood cancer survivors: a randomized placebo-controlled trial. [2009.07]
OBJECTIVES: To investigate the frequency and severity of side effects of methylphenidate among childhood survivors of acute lymphoblastic leukemia and brain tumors and identify predictors of higher adverse effect levels... CONCLUSIONS: Methylphenidate is generally well tolerated by childhood cancer survivors. There is a subgroup at increased risk for side effects that may need to be closely monitored or prescribed a lower medication dose. The seemingly paradoxical findings of increased "side effects" at baseline must be considered when monitoring side effects and designing clinical trials.
Behavioral response to methylphenidate challenge: influence of early life parental care. [2009.07]
Rat studies have shown that pups subjected to suboptimal rearing conditions exhibited permanently dysregulated dopamine activity and altered behavioral responses to dopamine stimulation. In humans, heightened stress-induced mesoaccumbens dopamine release in adults reporting low maternal care experience has been shown...
Safety of methylphenidate following traumatic brain injury: impact on vital signs and side-effects during inpatient rehabilitation. [2009.06]
OBJECTIVE: The aim of the present study was to evaluate the safety of methylphenidate administered during inpatient rehabilitation following traumatic brain injury... CONCLUSION: Methylphenidate given at 0.3 mg/kg body weight appears to be safe in the inpatient rehabilitation phase. This trial is registered with the Australian New Zealand Clinical Trials Registry (12607000503426).
Effects of application to two different skin sites on the pharmacokinetics of transdermal methylphenidate in pediatric patients with attention-deficit/hyperactivity disorder. [2009.06]
OBJECTIVE: This study was conducted to quantify the rate and extent of methylphenidate (MPH) absorption from a transdermal system when applied to two different skin sites in pediatric subjects with attention-deficit/hyperactivity disorder (ADHD)... CONCLUSION: MTS applied to both hip and scapular areas resulted in quantifiable plasma levels of d,l-MPH. Bioavailability of MPH from the same transdermal delivery system appears to differ substantially when applied to two different skin surfaces in young children but with similar overall skin effects assessments.
Clinical Trials Related to Ritalin LA (Methylphenidate)
A Comparative Effectiveness Study Evaluating OROS® Methylphenidate HCl, Ritalin® (Methylphenidate HCl), and Placebo for the Treatment of Attention Deficit Hyperactivity Disorder in Children [Completed]
An Effectiveness and Safety Study Evaluating OROS® Methylphenidate HCl, Ritalin® (Methylphenidate HCl) and Placebo in Children With Attention Deficit Hyperactivity Disorder [Completed]
The purpose of this study is to provide data on the effectiveness of the OROS®
Methylphenidate 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.
A Double-Blind Randomized, Placebo-Controlled, Crossover Study of Single Doses of OROS Methylphenidate Hydrochloride (CONCERTA) and Long-Acting Methylphenidate Hydrochloride (RITALIN LA) in Healthy Adults [Completed]
This is a double-blind, placebo-controlled study, three-period crossover study to examine the
likeability of a single dose of OROS MPH (CONCERTAÃ’ 90mg) and a single dose of Long-acting
MPH (RITALIN LAÃ’ 90mg). Hypotheses are as follows:
Hypothesis 1: OROS-MPH (CONCERTAÃ’) will be later than SODOS-MPH (RITALIN LAÃ’) in its Tmax
(time to Cmax).
Hypothesis 2: The subjective feelings of detection and likeability would be greater for
SODOS-MPH (RITALIN LAÃ’) than for an equivalent total dose of OROS-MPH (CONCERTAÃ’).
A Multicenter Study Comparing the Efficacy and Safety of OROS® Methylphenidate HCl, Ritalin® (Methylphenidate HCl) and Placebo in Children With Attention Deficit Hyperactivity Disorder [Completed]
The purpose of this study is to evaluate the efficacy and safety of OROS® Methylphenidate HCl
as compared with placebo and standard immediate-release Ritalin® (taken three time per day)
for the treatment of Attention Deficit Hyperactivity Disorder in children. Both OROS®
Methylphenidate HCl and Ritalin® contain the central nervous system stimulant,
methylphenidate HCl.
Naturalistic Substitution of Concerta in Adult Subject With ADHD Receiving Immediate Release Methylphenidate [Completed]
This is a single-blind study looking at the efficacy and satisfaction of Concerta
substitution in adult subjects with ADHD receiving immediate release methylphenidate.
Subjects will be administered a maximum dose of 1. 3mg/kg/day of either methylphenidate or
Concerta. The specific hypotheses of this study are:
Hypothesis 1: ADHD symptomatology in adults with DSM-IV, ADHD will continue to be controlled
in patients switched from MPH IR TID to Concerta.
Hypothesis 2: Patient satisfaction will not decrease in patients switched from MPH IR TID to
Concerta (ie., all patients will be equally or more satisfied on Concerta as compared with
MPH IR TID.
