22 Clinical Trials for Various Conditions
This study aims to adapt an outpatient mobile app-based contingency management intervention to the hospital setting to understand how we can use contingency management to improve health outcomes in hospitalized patients with stimulant use disorders.
This is a proof-of-concept randomized clinical trial of psilocybin-enhanced psychotherapy versus treatment-as-usual among individuals being treated for methamphetamine use disorder.
This Phase I behavior therapy development study seeks to improve treatment outcomes for methamphetamine (MA)-dependent subjects by developing a novel cognitive behavioral therapy- (CBT-) based short message service (SMS) text messaging intervention.
The investigators recently conducted a double-blind, randomized controlled trial (n=60) of limited duration (12 weeks), and found that compared with placebo, oral mirtazapine, an FDA-approved antidepressant, significantly reduced meth use in those receiving mirtazapine, as determined by reduction in meth-positive urines. Sexual risk behaviors also declined significantly in the mirtazapine arm compared to placebo. Mirtazapine decreased meth use despite low adherence: by medical event monitoring system (MEMS) caps, only 48.5% of daily doses were taken. All participants received weekly substance use counseling and monthly, brief clinician-delivered adherence counseling. The investigators propose expanding upon these results by lengthening the treatment period to 24 weeks, with adherence reminders added to the counseling, and determining if efficacy is sustained up to 12 weeks after drug discontinuation. The sample size for this 9-month study is 120.
Extended-release naltrexone (XR-NTX, VIVITROL) is an FDA-approved medication with efficacy in treating alcohol dependence and prevention of relapse to opioid dependence. It has shown promise in reducing relapse to amphetamine use among amphetamine-dependent, yet currently amphetamine-abstinent heterosexuals. The investigators will expand upon this promising work to determine whether monthly intramuscular injections of naltrexone will reduce methamphetamine (meth) use among actively using, meth-dependent men who have sex with men (MSM) in this double-blind randomized controlled trial of extended-release naltrexone versus placebo. The investigators will focus on MSM because of the disproportionate and intertwining epidemics of meth use and HIV in this population.
This study seeks to decrease methamphetamine use and concomitant high-risk sexual behaviors among methamphetamine-using men who have sex with men (MSM) by combining a biomedical intervention with a behavioral intervention. The behavioral intervention will consist of an 8-week course of contingency management (CM) through which participants will be reinforced for testing negative for methamphetamine metabolites during periodic urine analyses. The biomedical intervention involves a 28-day course of an antiretroviral drug (Truvada) to be administered after an unanticipated HIV risk exposure (i.e., engaging in either receptive or insertive anal sex without a condom with someone who is HIV-positive or of unknown status). In combining these two interventions, this study seeks to evaluate the combined intervention's effects on sexual risk behaviors and methamphetamine use.
In this parallel group clinical pharmacology laboratory experiment, we will assess pharmacodynamic interactions (with a focus on cardiovascular effects) of a 15 mg intravenous methamphetamine dose and single oral doses of reserpine (0.5 and 1.0 mg) or placebo.
The purpose of this study is to assess the potential interactions between intravenous methamphetamine and oral Modafinil.
The purpose of this study is to determine if different reinforcement procedures (i.e., schedules) produce different patterns of long-term abstinence from methamphetamine. We anticipate that the three contingency management conditions will promote longer periods of abstinence in the year following treatment relative to the standard control group. Furthermore, we predict that the intermittent reinforcement procedures will produce longer periods of continued abstinence (i.e., long-term behavior change) in the year following treatment than the continuous reinforcement procedure. Finally, we predict that the intermittent unpredictable schedule will produce longer lasting behavior change than the intermittent predictable schedule. Methamphetamine use will be measured using urine toxicology and self-report of methamphetamine use.
To assess the safety and tolerability of 7.5, 15 and 30 mg of sublingual lobeline.
The purpose of this study is to assess the interactions between intravenous methamphetamine and aripiprazole.
The purpose of this study is to assess the efficacy and safety of bupropion in reducing methamphetamine use in subjects with methamphetamine dependence
The purpose of this study is to assess ondansetron for the treatment of methamphetamine dependence.
The purpose of this study is to assess potential interactions between intravenous (IV) methamphetamine and oral bupropion.
The purpose of this study is to assess the potential interactions between intravenous methamphetamine and oral selegiline.
Part II: Examine cognitive performance of stimulant abusers (methamphetamine and cocaine) during recovery by assessing their cognitive function at monthly intervals.
The purpose of this study is to determine whether DAT availability, assessed by WIN binding, in the striatum is altered in cocaine or methamphetamine dependence. To determine whether DA synthesis capacity, assessed by FDOPA uptake, in the striatum is altered in Coc or Meth dependence. To determine whether the PET tracers, WIN or FDOPA, will differentiate Meth induced alterations from those induced by Coc use. To determine whether the PET characterization of striatal alterations observed at 3-5 days since last drug use persists at least 3 months after last drug use.
The purpose of this study is to characterize the cognitive performance of methamphetamine abusers by comparing them with cocaine abusers and normal controls.
The purpose of this study is to evaluate efficacy of tyrosine as a treatment for methamphetamine dependence in an outpatient treatment setting providing group psychosocial interventions. Examine effect of tyrosine on abstinence, retention in treatment, and craving."
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.

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.
