Active clinical trials for "Attention Deficit Disorder with Hyperactivity"

The purpose of this study is to assess the efficacy, the quality of life, and the safety of multiple dosing atomoxetine in Asian adult subjects with attention deficit/hyperactivity disorder (ADHD).

The primary purpose is to assess the efficacy of once daily dosing with optimized SPD503 (1, 2, 3 and 4mg/day), dosed either in the morning or evening, compared to placebo, in children with ADHD as measured by change from baseline score at endpoint on the ADHD-RS-IV.

ADHD has been associated with persistent deficits in the efficient allocation of attention and supports the notion that regulation of the cholinergic system may improve these cognitive deficits in ADHD. It has been suggested that the effects of nicotine are most pronounced on tasks that demand effortful processing (Rusted and Warburton 1994). In addition, a recent theory proposes that the cholinergic system allocates additional attentional resources during tasks that are demanding (i.e. sustained attention, set shifting, etc; Sarter and Bruno 1997). Thus it may be that in ADHD, cholinergic systems are under-responsive or under-developed and thus stimulation of nicotinic receptors via nicotinic agents may result in improved cognitive performance particularly on tests requiring effortful processing.

The overall goal of the present project is to investigate whether lisdexamphetamine (LDX; Vyvanse) is an effective adjunct to nicotine replacement therapy (NRT) to promote smoking cessation in patients with comorbid Attention Deficit Hyperactivity Disorder (ADHD) and nicotine dependence. The investigators hypothesized initially that smokers with ADHD who are optimized to a dose of LDX prior to quitting smoking and who remain on this dose of medication after quitting will remain abstinent longer than patients who are treated with placebo before and after quitting.However due to recent key issues that have arisen showing that initiation of stimulant treatment while subjects are actively smoking may facilitate increased smoking, and given that the study was still in the very early stage of study execution, the investigators revised the study design to use an empirically validated pretreatment approach with NRT and to initiate LDX treatment on the first post quit date in order to reduce the withdrawal symptoms that accompany smoking cessation. The overall rationale for this revised study design remains similar to the original.

The purpose of this trial is to determine if the study medication, CONCERTA (methylphenidate HCl), is safe and effective in improving academic performance and behavior in children with attention deficit hyperactivity disorder (ADHD), when compared to placebo.

This study is designed to provide pharmacokinetic data for the assessment of bioequivalence of Ritalin LA formulation compared to Medikinet ret. concerning plasma levels and efficacy measures. The primary objective of the study is to determine the pharmacokinetic parameters and bioequivalence of Ritalin LA compared to Medikinet retard, both given as oral o.d. doses of 20 mg over 7 days in children with ADHD. The secondary objectives are to assess the efficacy, safety and tolerability of Ritalin LA and Medikinet retard and the association of these parameters with plasma levels.

The primary objective of this clinical study is to assess overall safety and tolerability as measured by discontinuation rate due to adverse events in doses up to 120 mg/day in relation to global clinical studies in adult subjects who meet Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV™) criteria for Attention-Deficit/Hyperactivity Disorder (ADHD).

The purpose of this study is to test if the investigational medication ABT-089 is a safe and effective treatment for adults with Attention-Deficit/Hyperactivity Disorder (ADHD).

The purpose of this study is to assess, in a controlled environment, the efficacy and safety of NRP104 and Adderall XR compared to placebo in treatment of children, aged 6-12, with ADHD.

This is a two-arm, parallel, randomized, double-blind, placebo-controlled Phase 4 multicenter trial to compare the whole day efficacy of atomoxetine versus placebo in children aged 6 through 12 years with Attention-Deficit/Hyperactivity Disorder (ADHD) treated in an inpatient, day-patient and outpatient setting in Germany. Core symptoms will be measured during once or bi-weekly visits, three times per visit-day, by a computer based Continuous Performance Test. Following an initial 3-28-day screening and washout phase, patients will be assigned to double-blind treatment with atomoxetine or placebo. In the verum arm, a one-week atomoxetine treatment period with the 0.5 mg/kg per day lead-in dose will be succeeded by a 7 week period at the target dose of 1.2 mg/kg per day.
