Proton Magnetic Spectroscopy in Children and Adolescents With Attention Deficit Hyperactivity Disorder (ADHD) Before and After Treatment With OROS Methylphenidate - Full Text View

Sponsor:	Massachusetts General Hospital
Information provided by:	Massachusetts General Hospital
ClinicalTrials.gov Identifier:	NCT00593112

Purpose

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.

Primary Outcome Measures:

H MRS Scan results [ Time Frame: before and after 6 weeks Concerta treatment ] [ Designated as safety issue: No ]

Enrollment:	20
Study Start Date:	November 2006
Study Completion Date:	May 2009
Primary Completion Date:	May 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Experimental	Drug: OROS methylphenidate Concerta is given in capsule form with a minimum dose of 18 mg/day and a max of 126 mg/day. Subjects take Concerta once per day for 6 weeks.
2 Healthy Volunteer Control group	Other: No intervention No intervention

Detailed Description:

The primary objective of this study is to use 1H MRS to assess Glutamate (Glu), myo-Inositol (Ino), and creatine + phosphocreatine (Cr) levels in brain regions of interest in 20 children with ADHD between the ages of 12-17 years old, before and after a six-week open treatment trial with OROS methylphenidate. For comparison, 1H MRS will also be obtained from 20 controls matched by age and gender. We also will scan 20 children with ADHD between the ages of 12-17 years old that are currently enrolled in the protocol entitled "Prevention of Cigarette Smoking in ADHD Youth with Concerta" (2003-P-001313) and on a stable dose of Concerta. These 20 children will be scanned once while on medication and once while off medication

Criteria

Inclusion Criteria:

Male or female subjects, 12-17 years of age.
ADHD subjects must meet study criteria for the "Prevention of Cigarette Smoking in ADHD Youth with CONCERTA Protocol"; #2003-P-001313.
Control subjects must not meet full DSM-IV criteria for Attention Deficit Hyperactivity Disorder, or any other current major psychiatric disorder.
Each subject and his/her authorized legal representative must understand the nature of this proposed study, and must sign informed consent and informed assent documents.
Subject and parent must have a level of understanding sufficient to communicate intelligently with the investigator and study coordinator, and to cooperate with study procedures.

Exclusion Criteria:

Clinically significant chronic medical condition including hepatic, renal, gastroenterologic, respiratory, cardiovascular (including ischemic heart disease), endocrinologic, neurologic, immunologic, or hematologic disease.
