Brief Summary:
This is an open label pilot study to obtain information on the best way to study young adolescents with Attention Deficit Hyperactivity Disorder (ADHD)who may also be at risk of developing substance abuse, in part because of their ADHD. The plan is to recruit older children/young adolescents (age 11-15) who have ADHD and also have an older sibling with substance abuse. The treatment for ADHD in the 11-15 year old will be Vyvanse, a novel preparation of dextroamphetamine in which the molecule is inactivated and only becomes activated when it is digested. This preparation is felt to be safer from diversion while at the same time providing treatment for the younger siblings in which a bad outcome has already occurred in the family, namely the older sibling's substance abuse. As mentioned, this is an open-label study, a feasibility study to see if we can use this approach to study and treat high risk youth before they develop substance abuse.

Condition or disease Intervention/treatment Phase
Attention Deficit Hyperactivity Disorder Drug: Vyvanse Phase 4

Detailed Description:

The study is a six month open-label treatment with Vyvanse, a novel preparation of the Attention Deficit Hyperactivity Disorder (ADHD) medication dextroamphetamine in which the drug is inactivated and only becomes reactivated when digested. Vyvanse is thought to be safer in youth at risk for substance use disorder because it is harder to abuse and divert. It is FDA approved to treat ADHD in children age 6 through 12. Although there are no negative studies in adolescents 13-15, efficacy has not been established in the latter age group.

In this study 30 adolescents (ages 11-15) will be identified who have Attention Deficit Disorder and are at risk for alcohol and substance use problems. We propose to treat their Attention Deficit Hyperactivity Disorder with Vyvanse in the hope that it may prevent ADHD from promoting the development of alcohol and substance abuse problems. Our main goal is to see if we can identify children who are at risk because they have an older sibling who already has a substance abuse problem and Attention Deficit Hyperactivity Disorder. This is dubbed "the younger sibling design." Families will be recruited via contacts in adolescent substance abuse treatment centers (e.g. Phoenix House, Odyssey House). Participating substance abuse treatment centers will inform families of our study. We will conduct two phone screens followed by an in person evaluation to determine eligibility. Relevant information includes family history with special emphasis on the growth and development of both children, as well as the results of a comprehensive clinical evaluation of the younger child. Subjects will therefore be the younger siblings of substance abusers in which both sibs have ADHD but only the older sib uses drugs or alcohol regularly. All subjects will receive active medication and all will be assessed weekly for the first three months of the study and monthly for three months thereafter. The assessments will focus on ADHD symptoms, substance use, and overall adolescent problem behaviors.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Pilot Study of Vyvanse™ (Lisdexamfetamine Dimesylate) in Adolescents (Ages 11-15) With ADHD and an Older Sibling With ADHD and Substance Dependence
Study Start Date : March 2008
Actual Primary Completion Date : January 2010
Actual Study Completion Date : March 2010

Arm Intervention/treatment
Experimental: Open Label Vyvanse
Open Label Vyvanse (lisdexamphetamine) in doses of 30-70 mgs over 8 weeks in younger siblings of substance abusing older siblings with a history of treatment for ADHD
Drug: Vyvanse
Patients will be titrated from 30 mgs to 50 mgs to 70 mgs over four weeks, as tolerated and as needed to control ADHD symptoms
Other Name: Lisdexamphetamine is marketed as Vyvanse

Primary Outcome Measures :
  1. Number of Participants With at Least 70% Reduction in ADHD Symptoms as Measured by Change in ADHD Rating Scale From First to Last Visit [ Time Frame: up to 24 weeks ]
    The outcome is the number of subjects who achieved a clinically meaningful reduction in ADHD symptoms. This is defined as a 70% reduction from baseline as measured by change in the ADHD Rating Scale (ADHD-RS). The ADHD RS quantifies symptoms on a 0-3 scale, 0 meaning never present, 1 sometimes, 2 often present, 3 very often present. For this study, the scale was clinician administered using both parent and adolescent to achieve a consensus score, or a best estimate on the clinician's part when consensus could not be achieved

Secondary Outcome Measures :
  1. Number of Participants With Low or no Substance Use During the Study vs the Number With Intermittent Use Judged by (1)Time Line Follow Back (Confidential Clinician Administered Record of Recent Substance Use) (2) Urine Toxicology. [ Time Frame: up to 24 weeks ]
    This outcome measure integrates data from self report supplied in the Time Line Follow Back (a self report summary of all substance and alcohol use over the previous week or month) with evidence from periodic (weekly to monthly) urine toxicologies.
