NCT ID: NCT00634439 Completed - ADHD Clinical Trials

Safety Study of Atomoxetine and Cerebrovascular Outcomes

Start date: January 2008
Phase: N/A
Study type: Observational

Using a proprietary insurance health claims database, Eli Lilly and Company has contracted with an external party to conduct a retrospective cohort study of health claims for the time period from 1 January 2003 through 31 December 2006 (with follow-up of patients through 30 June 2007). This study will evaluate the potential association between atomoxetine and cerebrovascular events. In this study, the incidence of selected cerebrovascular outcomes as represented in health claims data among adult patients who initiate therapy with atomoxetine will be estimated. In particular the study will focus on cerebrovascular accident (CVA) and transient ischemic attack (TIA) as the outcomes of interest. The incidence for each outcome among atomoxetine initiators will then be compared to the incidence in a cohort of similar patients who initiate stimulant treatment and an age and gender-matched general population cohort. The atomoxetine and stimulant-initiating cohorts will be matched on a broad variety of variables, including age, gender, diagnoses, medication use, and healthcare utilization through the use of propensity score matching in order to minimize the influence of confounding by indication. The analysis will include the cohorts (atomoxetine and stimulant initiators) from a previous completed study with increased follow-up time (1 January 2003 through 30 June 2007) and accrue new atomoxetine and stimulant ADHD medication initiators over a 2 year period, so that the study will represent initiators between January 1, 2003 and December 31, 2006 with follow-up through June 30, 2007.

NCT ID: NCT00593112 Completed - ADHD Clinical Trials

Proton Magnetic Spectroscopy in Children and Adolescents With ADHD Before and After Treatment With OROS Methylphenidate

Start date: November 2006
Phase: Phase 4
Study type: Interventional

This will be an open label study using daily does of up to 126mg/day of Concerta in the treatment of children and adolescents, ages 12-17, who meet DSM-IV criteria for ADHD. Specific hypotheses are as follows: Hypothesis 1: Children and adolescents with ADHD will have significantly higher ACC and DLPFC Glutamate/myo-Inositol containing compounds (Glu/Ino) and Glutamate/creatine + phosphocreatine (Glu/Cr) than matched HCS. Hypothesis 2: After six weeks of treatment, OROS methylphenidate will lower ACC and DLPFC Glu/Ino and Glu/Cr levels in children with ADHD who are methylphenidate responders.

NCT ID: NCT00586573 Completed - ADHD Clinical Trials

Open-Label Pilot Study of Namenda in Adult Subjects With ADHD and ADHD NOS

Start date: March 2007
Phase: Phase 4
Study type: Interventional

The primary objective of the study is to assess the efficacy and tolerability of a 12-week trial of memantine hydrochloride administered twice daily in 20 adults (ages 18-55) with ADHD and ADHD NOS. Improvement will be defined as: 1) changes from baseline on the investigator-rated DSM-IV based ADHD Rating Scale; 2) changes from baseline in a questionnaire aimed at assessing executive functions (BRIEF); and 3) changes from screening in a computerized neuropsychological battery (CANTAB). We hypothesize that memantine hydrochloride will be associated with improving ADHD symptoms and associated deficits in executive functions. We also expect that memantine will be well-tolerated with predictable adverse events.

NCT ID: NCT00586157 Completed - Clinical trials for Attention Deficit Hyperactivity Disorder

Study of Medication Patch to Treat Children Ages 6-12 With ADHD

Start date: September 2006
Phase: Phase 4
Study type: Interventional

The purpose of this study is to investigate the effectiveness of a medication skin patch called Methylphenidate Transdermal System (MTS). We will compare the MTS medicated patch to a placebo patch. We want to find out how well it treats ADHD during the early morning hours before a child leaves for school or summertime routines.

Study of Atomoxetine and OROS Methylphenidate to Treat Children and Adolescents Ages 6-17 With ADHD

Start date: January 2004
Phase: Phase 4
Study type: Interventional

The purpose of this study is to evaluate the safety, effectiveness, and tolerability of atomoxetine and OROS methylphenidate, taken together, in the treatment of ADHD in children and adolescents ages 6-17.

NCT ID: NCT00579267 Completed - Anxiety Disorders Clinical Trials

Reliability and Validity of the MINI International Neuropsychiatric Interview for Children and Adolescents (MINI-KID)

Start date: February 2004
Phase: N/A
Study type: Observational

The primary aims of this study are to assess: 1. The inter-rater and test-retest reliability of the MINI-KID 2. The validity of the standard MINI-KID interview in relation to the parent rated pencil/paper version (MINI-KID-P) and th longer clinician rated "Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime Version (K-SADS-PL) and "expert opinion" (when available). Secondary aims will include evaluating the concordance between: The Children's Global Assessment Scale (a required part of the K-SADS) with the clinician-rated Sheehan Disability Scale (to be administered with the MINI-KID) as a measure of illness severity.

NCT ID: NCT00573859 Completed - ADHD Clinical Trials

The Reinforcing Mechanisms of Smoking in Adult ADHD

Start date: September 2006
Phase: Phase 1/Phase 2
Study type: Interventional

Whereas the smoking prevalence rates in the general population are declining, rates among people diagnosed with attention-deficit hyperactivity disorder (ADHD) continue to be elevated. Smoking may be a form of self-medication in people with ADHD, which has specific reinforcing mechanisms such as improvement of ADHD core symptoms, enhancement of moods and arousal, or a combination of both. In addition, the reinforcing effects of smoking may be potentiated by stimulant medication. The study examined the reinforcing effects of ad libitum smoking with and without ADHD medication in adult smokers with clinically diagnosed ADHD. Participants were adults with ADHD. The effects of two day of ADHD medication compared to two days on placebo for were studied on nicotine intake (i.e., cotinine levels). In addition, task performance on the Continuous Performance Task and nicotine withdrawal symptoms were examined in response to ADHD medication + smoking a cigarette versus ADHD medication + abstinence versus placebo medication + smoking versus placebo medication + abstinence. The study identified the reinforcing mechanisms of smoking in interaction with ADHD medication. The findings will contribute to a better understanding of nicotine addiction and facilitate the development of targeted smoking cessation and prevention programs for individuals with ADHD and other people with deficiencies in impulse control and excessive risk taking.

NCT ID: NCT00573248 Completed - ADHD Clinical Trials

Nicotine and Behavior in Adult ADHD

Start date: August 2005
Phase: N/A
Study type: Interventional

Attention deficit hyperactivity disorder (ADHD) is characterized by inattention, impulsivity, and hyperactivity that are frequently treated with stimulant medications such as Ritalin. Many people with ADHD smoke. The smoking prevalence rates are estimated to be 40% in adults with ADHD compared to 20% in the general population. People with ADHD have also more difficulty to quit smoking. Only 29% of smokers with ADHD quit smoking compared to 48.5% of smokers in the general population. Nicotine is a stimulant, which may have properties similar to stimulant medications (e.g., Ritalin) used to treat ADHD. Nicotine may increase attention and reduce hyperactivity and impulsivity and, thus, may regulate behavior in individuals with ADHD. Alleviating the symptoms of ADHD and increasing cardiovascular activity through smoking may mimic the effects of stimulant medications and can be a form of self-medication. The major objective of the study was to examine the effects of nicotine on ADHD symptoms, moods, and cardiovascular activity. The study investigated the effects of nicotine patches on behavioral regulation in adult smokers and nonsmokers with ADHD. Smokers and nonsmokers with ADHD participated in two conditions: (1) nicotine patch and (2) placebo patch. During each condition, symptoms, moods, and side effects were assessed for 2 days during waking hours. An electronic handheld diary, programmed to prompt the participant twice per hour, recorded ADHD symptoms (e.g., difficulty concentrating, impulsivity, etc.), negative moods (e.g., anger, stress), and nicotine side effects (nausea, dizziness). Heart rate and blood pressure were recorded with lightweight ambulatory monitors to indicate cardiovascular activity. Results provided information about the effects of nicotine patches on behavioral regulation in adult smokers and nonsmokers with ADHD. The inclusion of nonsmokers was important to clarify whether the effects of nicotine on smokers was due to smoking withdrawal. The findings help explain the increased smoking prevalence rates and reduced quit rates associated with ADHD. Knowledge about nicotine's effects on behavioral regulation can help to develop successful smoking cessation programs for individuals with ADHD. The findings on cardiovascular activity may help determine the potential risk for cardiovascular disease in smokers and nonsmokers with ADHD. The study contributed to understanding nicotine's effects on behavioral regulation in a highly vulnerable population such as people with ADHD.

NCT ID: NCT00561340 Completed - ADHD Clinical Trials

Study of the Effect of Calorie Supplementation on Growth in Young Children on ADHD Medication

Start date: January 2, 2006
Phase: N/A
Study type: Interventional
