Filter by:The purpose of this study is to evaluate PET methodology to study in vivo synaptic dopamine release.
The purpose of this study is to define pathophysiological subtypes of abnormalities in subjects with cocaine dependence.
The purpose of this study is to assess the effects of chronic cocaine use on the acoustic startle response and on gating of this response in humans.
The purpose of this study is for the modeling of impaired judgement in cocaine abusers.
The purpose of this study is the use of Methylphenidate in the treatment of cocaine dependence and Attention Deficit Hyperactivity Disorder (ADHD) comorbidity.
The purpose of this study is the use of Nefazodone in the treatment of cocaine dependence and depression comorbidity.
The purpose of this study is the use of buprenorphine/naloxone in treatment of opioid dependence.
The purpose of this study is to evaluate the effect, pharmacokinetics and dose proportionality of buprenorphine when administered to non-dependent opiate users. 1) To evaluate whether plasma concentrations of buprenorphine increase proportionally to buprenorphine dose. 2) To evaluate the dose-response of subjective and physiological effects of buprenorphine; and 3) To determine the safety of buprenorphine.
The purpose of this study is to determine the efficacy and safety of a buprenorphine/naloxone sublingual tablet formulation as an office-based therapy for opiate-dependence treatment. The developmental objective for this combination product is an expansion of therapeutic options for the treatment of opiate dependence.
This trial is a continuation of the Multimodal Treatment Study of Children with Attention Deficit Hyperactivity Disorder (MTA Study). Continuation Aim 1 is to track the persistence of intervention-related effects as the MTA sample matures into mid-adolescence, including subsequent mental-health and school-related service utilization patterns as a function of MTA treatment experience (treatment assignment) and outcome (degree of treatment success at 14 mo.). Aim 2 is to test specific hypotheses about predictors, mediators, and moderators of long-term outcome among children with ADHD (e.g., comorbidity; family functioning; cognitive skills; peer relations) that may influence adolescent functioning (either independent of or through initial treatment assignment and/or 14-month treatment outcomes); and to compare how these predictors, mediators, and moderators are similar or dissimilar within the normal comparison group. Aim 3 is to track the patterns of risk and protective factors (including their mediation or moderation by initial treatment assignment and/or outcome) involved in early and subsequent stages of developing substance-related disorders and antisocial behavior. Aim 4 is to examine the effect of initial treatment assignment and degree of treatment success on later academic performance, achievement, school conduct, tendency to drop out, and other adverse school outcomes. In the original MTA design, patients were randomly assigned to 1 of 4 treatment conditions: (1) medication only; (2) psychosocial only; (3) combined (medication and psychosocial); or (4) Assessment-and-Referral condition. All but the latter were treated intensively for 14 months, with assessments for all subjects at baseline, 3, 9, 14, and 24 months. The original MTA design thus provides short-term (10 months post-treatment) follow-up at 24 months. This continuation extends the follow-up to assessments at 36, 60, and 84 months after treatment. A child may be eligible for this study if he/she: Is 7 - 9 years old, and has Attention Deficit Hyperactivity Disorder (ADHD).
