13 Clinical Trials for Various Conditions
The purpose of this study is to determine whether Integrated Cognitive Behavioral Therapy or Twelve Step Facilitation Therapy is most effective for treatment of dually diagnosed veterans with depressive and substance use disorders.
The purpose of this study is to investigate if health interventions (intensive exercise or health education) can be used to help improve substance abuse treatment. The primary objective of this protocol is to compare percent days of abstinence between Vigorous Intensity High Dose exercise (VIHD) and Health Education Intervention (HEI) groups based on stimulant (i.e., cocaine, methamphetamine, amphetamine, or other stimulant, excluding caffeine and nicotine) use during a 12-week acute phase.
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.

The purpose of the study is to determine feasibility of repetitive transcranial magnetic stimulation (rTMS) for individuals with moderate to severe cocaine or methamphetamine use disorder (CUD/MUD). Potential participants will be age 18-65, and interested in cutting down or stopping use. Participants will be randomized to one of two groups; groups will receive rTMS or sham rTMS (placebo) over the course of an 8-week treatment period, and complete follow-up assessments at the end of treatment, 12, and 16 weeks post-randomization.
This study will leverage extracted leukocyte DNA specimens from a completed NIH-funded project to examine the efficacy of a behavioral intervention model that reduced stimulant use on DNA methylation over 6 months.
This study will evaluate the efficacy of ondansetron compared with placebo in the treatment of cocaine dependence.
This placebo-controlled, double-blind, randomized pilot clinical trial will evaluate atomoxetine (Strattera®) for the treatment of cocaine dependence. Cocaine-dependent individuals, who are healthy and are seeking treatment for their substance abuse, will be randomized to receive either atomoxetine (n=25) or a matched-placebo (n=25) during a trial lasting 12 weeks; there will be a double-blind, ascending dose lead-in order to achieve maintenance on the assigned active dose safely. Contingency management procedures will be used to reinforce attendance and compliance with study procedures. Primary outcome measures will include urinalysis data assessing cocaine use.
The hypotheses of this study are: 1. Ondansetron will show a decrease in cocaine use from baseline in individuals with HIV who are cocaine using. 2. Ondansetron will show a decrease in cravings from baseline in individuals with HIV who are cocaine using. After informed consent and screening, HIV infected individuals who are cocaine dependent and qualify for the study will be offered ondansetron 4mg BID for six weeks in an open label format 4mg BID has been found to have efficacy compared to placebo. At screening and then at each visit, they will be asked to provide urine and a drug of abuse screen will be conducted to assess for cocaine. They will be asked to detail their recent cocaine use in the last month and then will be given a visual analog scale to assess their craving for cocaine. They will be asked to return weekly for 6 weeks to receive a week's supply of ondansetron and to give a urine sample that will test for cocaine. They will fill out a time line follow back for the past week and asked to assess their craving for cocaine on a visual analog scale.
The primary aim of this project is to use a randomized single-blind sham-controlled study to investigate if high frequency repetitive transmagnetic stimulation (HF-rTMS) can modulate cue-induced craving in adult methamphetamine (METH) users. The investigators hypothesize that HF-rTMS directed at left dorsolateral prefrontal cortex (DLPFC) will result in a reduction in craving for METH compared to sham-controlled rTMS in adults with methamphetamine use disorder (MUD) as evidenced by validated measures of METH craving. Neurobiologically, the investigators anticipate rTMS mediated stimulation of the DLPFC could result in inhibition of cue-induced craving through potential disruption of involved circuitry. The current project proposes that participants who are recently abstinent from METH will be randomized into four experimental groups to provide two rTMS conditions (real versus sham) and two picture cues conditions (METH versus neutral). The experiment will have an induction phase where each subject will receive 10 daily treatments within 2 weeks. Just before each rTMS/sham session participants will be shown visual cues (METH or neutral). Participants will then undergo a maintenance phase for an additional month with assessments to evaluate craving and relapse. Urine samples for urine drug screening (UDS) will be collected at screening day and on days 1, 5 and 10. Just before each rTMS/sham session participants will be shown visual cues (METH and neutral). VAS craving scores will be assessed before and after picture presentation and after the rTMS/sham session. Before the first and 10th treatment session, participants were evaluated by the the Stimulant Craving Questionnaire (STCQ) and the Severity of Dependence Scale (SDS) questionnaires. Participants will then undergo a maintenance phase for an additional month. During the first week of maintenance, three rTMS/sham sessions will be administered. During each of the following 3 weeks, one rTMS/sham session will be given per week. As with the induction phase, urine samples will be collected for screening and STCQ and the SDS questionnaires will be completed at each maintenance session. To evaluate the long-term effects of the rTMS treatment, the investigators plan on contacting participants 6 months after treatment termination for all subjects who completed the 10 treatment sessions. During that phone conversation, craving and relapse will again be assessed.
This study is designed to collect data to determine whether a medication, ibudilast, is safe for use as a potential treatment for methamphetamine-dependent people. For 18 years in Japan and South Korea, ibudilast has been used safely in humans as a treatment for asthma, pulmonary, and cardiovascular disease. It is not known whether ibudilast is safe to use in outpatient settings with people who have methamphetamine dependence. This would be the first study to collect this information. This study is important because individuals with methamphetamine dependence often relapse to meth use, even when in treatment; some number of individuals who participate in an outpatient study will relapse to methamphetamine while taking ibudilast. It is crucial to know whether there may be interactions between ibudilast and methamphetamine before planning an outpatient clinical trial.Ibudilast is an exciting medication candidate for treating methamphetamine dependence. When individuals become abstinent from methamphetamine during early recovery, the body starts an inflammatory process in neurons, especially glial cells. Glial cells are important in that they provide support to the nerve cells that are involved in thought, movement, and other human activities. By dampening inflammation in glial cells, ibudilast may preserve glial and other nerve cells during early abstinence, which in turn may help individuals feel better and think better during treatment. The study specific aims are to determine whether ibudilast alters: 1. blood pressure and heart rate responses to methamphetamine; 2. the ratings of craving or other drug experiences from methamphetamine; 3. the reward/reinforcing effects of methamphetamine; and 4. the metabolism of methamphetamine. Over an enrollment period of 24 months, 12 methamphetamine-dependent participants who are not looking for treatment will complete this study.
Background: * Cues related to past drug use induce a particular pattern of brain activation, which has been correlated with craving for cocaine in active cocaine abusers. Researchers are interested in determining the role of the brain chemical dopamine in cue-elicited as well as spontaneous craving for cocaine. * To study the role of dopamine in cocaine craving, researchers will use positron emission tomography (PET) to compare the neural reactions of cocaine users with those of non-substance-abusing healthy volunteers. Researchers hope that the data gathered from this study will lead to the development of more effective anti-craving medications. Objectives: * To clarify the role of dopamine in cue-elicited responses that contribute to cocaine abuse. * To determine if PET results of this study differ with various means of administering PET chemicals. Eligibility: - Individuals 21 to 44 years of age who are either current cocaine users (at least twice per week) or healthy volunteers without a history of drug abuse. Design: * Cocaine-using participants will enter the inpatient clinical research ward at the National Institute on Drug Abuse (NIDA) Addiction Research Center for 2 nights before the day of the study. In addition, these participants will stay overnight at NIDA the evening after each PET session and will be discharged the following day. Cocaine-using participants will be required to perform a balance test before the study to provide a baseline response in case they require anti-anxiety medications to cope with the effects of the study. * Control subjects will not be required to stay overnight and will arrive as outpatients for the PET session. All participants will be required to abstain from alcohol and caffeine consumption from midnight before each study session, and will not be permitted to smoke on the day of testing. * - On the day of the study, participants will undergo a practice session to set up the PET scanning equipment. Following the practice session, participants will be shown video recordings of images that are related to nature (e.g., seashells) or to drug abuse (e.g., drug paraphernalia). Participant reactions will be studied through the PET monitoring, and the study will be conducted in two separate PET sessions with a break in between. Individuals in the cocaine-using group may receive anti-anxiety medication if the stimulus cues increase anxiety related to cocaine craving. * Different groups of participants will receive different methods of PET chemical administration, and researchers will compare these methods.
This research compares the benefits of the original treatment, Community Reinforcement and Family Training (CRAFT), with the Treatment Entry Training (TEnT) component of CRAFT to determine if TEnt alone can produce the primary outcome of CRAFT -- treatment entry of the drug user. We also look at the impact on the well-being of the concerned significant other and the drug use of their loved one.
