An Assessment of the Safety of Varenicline in Methamphetamine-dependent Volunteers
Description

More people worldwide use amphetamine-type stimulants than any illicit drug besides cannabis, and methamphetamine (MA) abuse and dependence is the fastest growing drug problem in the United States. Much work remains in identifying an effective pharmacotherapy for MA dependence. The neurobiological actions produced by MA involve dopamine (DA), serotonin, and norepinephrine, but also include alterations to cholinergic neurotransmitter systems. Candidate compounds that target acetylcholine (ACh) are attractive options for development that have not received adequate attention. Varenicline is a drug that increases the release of DA in the brain and it is logical to assume that it would to some extent compensate for the reduction in these neurotransmitters that occurs in MA withdrawal. Current research has linked certain genes that are related to neurotransmitters with drug abuse and memory impairment (e.g., A1 allele for the D2 dopamine receptor and catechol-O-methyltransferase). We will take blood samples and test for these genes in order to relate the findings to brain function. This is a double-blind, placebo-controlled, within-subjects study to determine the safety and tolerability of MA in MA-dependent volunteers treated with varenicline and placebo.

Study to Evaluate the Likeability, Safety, and Abuse Potential of NRP 104 in Adults With Histories of Stimulant Abuse
Description

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.

Preventing Parental Opioid and/or Methamphetamine Addiction Within DHS-Involved Families: FAIR
Description

Young parents aged 16 to 30, involved in the DHS system for child welfare or self-sufficiency needs are at risk for opioid use disorder and/or methamphetamine use disorder (OUD; MUD). Those identified as engaging in opioid or methamphetamine misuse are at high risk for escalation. Children of parents with OUD and MUD are at-risk for entering into foster care. Oregon is one state particularly affected by this challenge. The proposed UG3/UH3 offers one potential solution by adapting and evaluating a recently developed treatment for parental OUD and MUD, for prevention. This study seeks to collaborate with Oregon Department of Humans Services (DHS) leadership to deliver a new outpatient prevention program to high-risk, young, parents. The Families Actively Improving Relationships (FAIR) program will include community-based mental health, parent management, and ancillary needs treatment, and ongoing monitoring and prevention services for opioid and methamphetamine use. This study will randomize 240 parents, aged 16 to 30, to receive FAIR or standard case management and referral, in two counties in Oregon. Outcomes will include an evaluation of the effectiveness of FAIR in addressing risk factors associated with substance use disorders in DHS-involved populations, OUD and MUD outcomes, and implementation outcomes including implementation process and milestones, and program delivery outcomes. Intervention and Implementation costs will be assessed, and the benefit of FAIR will be evaluated in relation to standard services, but also in relation to capacity and population needs. Study hypotheses are: (1) Parents randomized to FAIR will be less likely to escalate opioid and/or methamphetamine use, and to receive a diagnosis of OUD and/or MUD; (2) Parents randomized to FAIR will experience significant reductions in mental health, parent skills, and ancillary needs compared to those receiving standard services; (3) Counties will follow the implementation plan developed in collaboration between study team members and state leadership, and that doing so will yield successful implementation of FAIR; and (4) Implementation and intervention costs for FAIR will demonstrate a benefit for offering FAIR compared to standard services, particularly in rural communities where capacity influences service delivery decisions.

Neurocognitive Empowerment for Addiction Treatment (NEAT) in Opioid Use Disorder and Amphetamine Use Disorder
Description

Chronic drug addiction is not only associated with increased mental health symptoms, such as anxiety and depression, but also with brain (neural and cognitive) deficits. These neurocognitive deficits (NCDs) in memory, attention, decision-making, self-control and judgement disturb normal daily functioning and attempts for abstinence. These NCDs are also associated with worse long-term treatment outcomes. Current treatment programs for addiction to opioids and amphetamines are mainly focused on abstinence from illicit drugs with or without assistance of medications, with the assumption that these NCDs will subsequently heal. However, NCDs are found to persist even after a long-term abstinence and are thought to contribute to relapse, decreases quality of life, or lack of reintegration into society. Furthermore, NCDs (particularly related to attention and memory) are considered a potential obstacle for engagement in therapy services for addiction and associated mood, anxiety and trauma-related comorbidities (i.e., cognitive-behavioral therapies). Brain rehabilitation programs focused on compensatory strategies and training exercises for NCDs associated with traumatic brain injuries, stroke, multiple sclerosis and schizophrenia has consistently been found to improve functioning and long-term outcomes for these populations. There have been a few preliminary attempts to transplant cognitive rehabilitation with substance use populations, with some limited promise. However, these previous studies failed to link cognitive strategies with the drug use and affective/craving symptoms experienced by patients and also did not fully incorporate knowledge gained from neuroscientific research on opioid and/or methamphetamine addiction specifically. The aim of this study is to characterize clinical efficacy for an intervention targeting NCDs in opioid and/or methamphetamine addiction by enhancing awareness and use of neurocognitive skills in the context of substance use recovery. This aim will be accomplished by randomizing 80 subjects with opioid and/or methamphetamine use disorder who are already enrolled in substance use treatment in the state of Oklahoma to also complete a novel "Neurocognitive Empowerment for Addiction Treatment" (NEAT) program developed by a group of investigators at Laureate Institute for Brain Research, Tulsa, Oklahoma. NEAT will be novel in (a) its use of cartoons, brain awareness games and real-life scenarios to ensure it is interactive and engaging, (b) the focus on the role of neurocognitive deficits in recovery from substance use and co-occurring mental health symptomatology, and (c) its incorporation of neuroscientific findings specific to substance use to the training and exercise strategies. Subjects will be followed up for twelve months after starting the program with different measures for addiction and mental health recovery to explore the efficacy of NEAT compared to the control intervention. Using LIBR's cutting-edge neuroimaging facilities before and after interventions, this study has the unique opportunity to monitor not only clinical outcomes but also potential changes NEAT may have on brain structure and function. In case of finding reasonable clinical efficacy for NEAT, it will be hopefully integrated as a manualized brain rehabilitation program to the substance use treatment programs.

Study of Medical Treatment for Methamphetamine Addiction
Description

Currently there are no medications approved for the treatment of methamphetamine addiction. Bupropion is an antidepressant that is approved by the Food and Drug Administration (FDA) for the treatment of depression and for cigarette smoking cessation but is not approved by the FDA for the treatment of methamphetamine addiction. Preliminary research studies suggest that bupropion may help people receiving treatment for methamphetamine addiction to reduce or to stop their methamphetamine use. But results of these studies also suggest that bupropion may help certain groups of patients more than others, such as men versus women and light versus heavy methamphetamine users, although the reasons for this difference are not known. One possibility is that a person's genetic make up may influence whether or not they respond to treatment with bupropion for methamphetamine addiction. The purpose of the study is to determine if bupropion is can help people reduce or stop their methamphetamine use and to investigate whether genetic variations influence whether people respond to treatment with bupropion for methamphetamine addiction, which may help doctors and patients better decide if treatment with bupropion will be beneficial or not. To identify possible genetic variations that influence response to bupropion, we will perform genetic tests on blood or saliva specimens from participants receiving treatment with either bupropion or placebo (which is a pill that contains no medication) in conjunction with standard cognitive behavioral therapy drug counseling. We will compare methamphetamine use, as assessed with urine drug screens, among participants receiving bupropion versus those receiving placebo to determine if bupropion helps people to reduce or stop their methamphetamine use. We will then compare the results of the genetic tests among participants who respond and who do not respond to bupropion. In addition, since the amount of methamphetamine a person uses was associated with response to bupropion in preliminary studies, we will also compare the results of genetic testing among persons with heavy versus light methamphetamine use before entering treatment. Results of this study have the potential to provide insights into the biology of methamphetamine addiction and help increase the understanding of how bupropion works. This information could be useful to develop effective medications for methamphetamine addiction and to improve the ability of clinicians to provide treatment to patients with methamphetamine addiction.

Psychology of Reward and Punishment: Functional and Molecular Brain Imaging and Monoaminergic Correlates
Description

Background: * Brain imaging studies, genetic research, and investigations of stress have provided more information about the role of dopamine in processing reward and punishment, and in vulnerability to substance dependence. Researchers are interested in learning more about how the brain responds to rewards, including drugs of abuse, and how these responses may involve genetic factors or previous stressful events. * Researchers intend to use the drug amphetamine to increase levels of dopamine in the brain and study the effects through two kinds of scanning: functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). Objectives: * To examine the relationship among dopamine function, brain activity, reward processing, genetic profile and exposure to stress in normal healthy adults. * To examine the variation in these factors between normal healthy adults and individuals with current cocaine-dependence. Eligibility: - Individuals 18 to 45 years of age who are either current cocaine users or healthy volunteers with no history of substance abuse or dependence. Design: * The study will consist of an initial evaluation session and six study visits, four of which will involve fMRI scans (3 hours each) and two of which will involve PET scans (8 to 9 hours each). * Cocaine-using participants will enter the inpatient clinical research ward at the National Institute on Drug Abuse Addiction Research Center the night before each scanning session and will be discharged the following day. Healthy volunteer subjects will not be required to stay overnight and will arrive as outpatients for the PET session. Participants will not be released until researchers have determined that participants are not experiencing significant effects of the drug. * Initial session (1): Participants will complete questionnaires about past reactions to stressful situations, and will be trained to do thinking tasks that will be performed in fMRI visits. The tasks will be practiced in a mockup of an MRI machine. * MRI sessions (2-5): Participants will receive either oral amphetamine or a placebo, and will perform thinking, short-term memory, and reward tasks during MRI scanning as directed by researchers. * PET sessions (6-8): Participants will receive either oral amphetamine or a placebo, and will provide blood samples during the PET scanning sessions. Participants will have short breaks during the PET scanning sessions.

A Pilot Trial of Modafinil for Treatment of Methamphetamine Dependence
Description

Patients treated for methamphetamine dependence have high rates of relapse, and no pharmacotherapy has yet been demonstrated to be efficacious. Modafinil (d, l-2-\[(diphenylmethyl) sulfinyl\] acetamide) is a novel wake- and vigilance- promoting agent that is chemically and pharmacologically dissimilar to CNS stimulants such as the amphetamines, methylphenidate, and pemoline. It is well tolerated and has low abuse liability compared to CNS stimulants. Modafinil is FDA approved for a variety of sleep disorders, may relieve methamphetamine withdrawal symptoms, improves cognitive function, has been shown to reduce cocaine use in dependent users, and is safe when co-administered with intravenous methamphetamine. We will conduct a pilot, open-label clinical trial of modafinil to establish its safety and efficacy as a pharmacotherapy for methamphetamine dependence. Specific Aims: 1. Determine the safety of modafinil in the treatment of methamphetamine dependence. 2. Determine the efficacy of modafinil in the treatment of methamphetamine dependence. 3. Assess the effect of modafinil on cognitive function in methamphetamine users. 4. Assess the effect of modafinil on methamphetamine withdrawal symptoms. 5. Compare the validity of a cellular telephone-based reporting system for assessing medication regimen adherence to conventional electronic medication monitoring. Hypotheses: 1. Modafinil will be as safe and well tolerated as placebo in a comparison group from another study. 2. Subjects given modafinil will use less methamphetamine than subjects given placebo. 3. Subjects given modafinil with demonstrate improvements in cognitive function when compared to subjects given placebo. 4. Subjects given modafinil will have reduced withdrawal symptoms when compared to subjects given placebo. 5. Adherence will be recorded more accurately by cellular telephone than by conventional electronic medication monitoring.
