Active clinical trials for "Substance-Related Disorders"

The overall goal of the research project is to improve the outcome of medical care for injection drug users (IDUs) with Hepatitis C viral (HCV) infection. Hypothesis: An intervention designed to improve the rate of HCV treatment completion and sustained virologic response (SVR) in IDUs will increase access by integrating HCV medical care into a substance abuse treatment program.

The purpose of this study is to evaluate the impact of treating depression on substance dependent teens.

This research is being done to evaluate if NRP104 is a safe drug. The other purpose is to learn if NRP104 produces a high and any other effects like amphetamine and other stimulant drugs that are abused. This information will give some indication if NRP104 can be abused. NRP104 is an investigational drug. This means that it has not been approved by the U.S. Food and Drug Administration (FDA). Healthy people, between the ages of 18 and 55 with histories of substance abuse that include stimulant drugs, may join. Amphetamines are drugs that are used most often to treat attention deficit hyperactivity disorder (ADHD) in children, to treat narcolepsy (excessive sleepiness) and for weight loss.

Zinc deficiency is prevalent in HIV infected individuals who abuse drugs. The purpose of this study is to determine if zinc therapy will prevent immune failure in HIV infected individuals who abuse drugs and have low plasma zinc levels.

The purpose of this study is the safety and efficacy of Buprenorphine/Naloxone in the treatment of opioid dependence. A compassionate use study.

The purpose of this study is to evaluate the efficacy of desipramine, sertraline, and placebo on methamphetamine dependent gay men with AIDS.

The purpose of this study is to determine the safety of lofexidine in the treatment of opiate withdrawal. Preliminary data will also be obtained to assess the ability of lofexidine to alleviate opiate withdrawal signs and symptoms.

The purpose of this study is to evaluate the behavioral and physiological effects of buprenorphine and naloxone, both alone and in combination.

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).

The purpose of this study is to evaluate desipramine and carbamazepine in reducing cocaine craving; increase outpatient treatment capacity and evaluate their incidence of psychiatric disorders.
