The goal of this clinical trial is to learn whether it is possible to use intramuscular (IM) ketamine in combination with psychotherapy to treat moderate-to-severe methamphetamine use disorder (MeUD) in publicly insured patients with or at-risk for HIV disease. The main questions it aims to answer are: * Do publicly insured patients find ketamine-assisted psychotherapy feasible and acceptable as a potential treatment for MeUD? * Is IM ketamine safe and tolerable among patients with MeUD? Participants will: * Receive 3 monitored doses of IM ketamine * Have 3 preparation and 4 integration psychotherapy visits * Report their daily amounts of methamphetamine used prior to, during, and up to 3 months following the intervention
This study aims to determine whether treatment response with IV ketamine is superior to treatment response with IV midazolam in adults with moderate to severe MUD. The study design is a 12-week randomized, double-blind, controlled trial comparing intravenous (IV) ketamine against IV midazolam, delivered over six weeks in 120 adults with moderate to severe methamphetamine use disorder (MUD).
In this project, the investigators examine behavior and associated brain activity during explore-exploit decision-making tasks performed pre- and post-modulation of affective state using autobiographical memory recall. The investigators hypothesize that a positive memory recall will reduce negative affective state, reduce explore-exploit biases and normalize the associated brain activity. The investigators propose a randomized double-blind, sham-controlled trial of positive autobiographical memory recall with 80 adults (n=40 per arm) with methamphetamine use disorder (MUD) currently involved in abstinence only treatment centers.
This study is using Transcranial Magnetic Stimulation (TMS) to determine if interventional psychiatry treatment can help with the treatment of Methamphetamine Use Disorder. Individuals with Methamphetamine Use Disorder will receive 5 consecutive TMS treatment sessions based off of randomization. Participants will be randomized to one of two groups. TMS treatment arm or sham-TMS arm.
The investigators will evaluate the effects of an accelerated Transcranial Magnetic Stimulation (TMS) protocol of the left dorsolateral prefrontal cortex (DLPFC) for moderate to severe methamphetamine use disorder. This is a randomized parallel group design to assess feasibility and safety, evaluate efficacy (use, craving) and identify magnetic resonance imaging (resting state and cue craving) associated with group/outcomes.
The primary objective of this study is to evaluate the efficacy of extended release naltrexone plus bupropion XL (XR-NTX/BUP-XL) compared to matched injectable and oral placebo (iPLB/oPLB) in reducing methamphetamine (MA) use in individuals with moderate or severe methamphetamine use disorder (MUD) seeking to stop or reduce MA use.
The overall goal of the study is to evaluate the effectiveness of a secondary prevention strategy implemented at a systems-level to prevent stimulant related overdoses.

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.
We propose a single-arm clinical trial, with historical controls as a comparison group for select outcomes. Subjects with MAUD will receive 16 sessions of dual-target theta burst stimulation to the DLPFC and MPFC over 4 weeks. We will follow outcomes for 12 weeks. Outcomes include treatment retention, craving, self-reported MA or stimulant use, urine drug screen results, depressive symptoms, anxiety symptoms, sleep quality, quality of life, response inhibition, and functional connectivity. Magnetic resonance imaging (MRI) to measure functional connectivity at baseline and four weeks.
This is a pilot study to test the feasibility of a recruitment strategy and study protocol to examine the effects of a dual target transcranial magnetic stimulation treatment in methamphetamine use disorder. The study will test intermittent theta burst stimulation (TBS) targeting the dorsolateral prefrontal cortex (DLPFC) combined with continuous TBS targeting the medial prefrontal cortex (MPFC) in people with methamphetamine use disorder (MAUD) who are engaged in psychosocial treatment. Intermittent TBS targeting the DLPFC is approved by the Food and Drug Administration for major depressive disorder, and continuous TBS targeting the MPFC has been studied in cocaine use disorder. We will administer this dual target TBS daily for 2 weeks, followed by three times weekly for 2 weeks, and monitor depressive symptoms, anxiety, sleep, craving, quality of life, and methamphetamine use for three months. Changes in functional connectivity of brain circuits will be evaluated with functional magnetic resonance imaging (fMRI) before and after treatment. We expect to observe changes in connectivity between the DLPFC, MPFC, and other regions implicated in addiction and impulsivity. Furthermore, we will evaluate if baseline differences in functional connectivity can be used to predict response. Psychological tests focusing on state impulsivity and risk taking will be administered, and we expect to observe reductions in these characteristics after treatment. We will test this protocol in 20 patients recruited from clinical care settings at University of Iowa Hospitals and Clinics, University of New Mexico Health System, and University of Utah Health to illustrate the feasibility of recruitment and completing the protocol, to support an external funding proposal.
The purpose of this research study is to determine the effects of an exercise intervention and health-education program on brain dopamine receptors and on cognitive functions that have been linked to these receptors.
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.
Methamphetamine use disorder (MUD) is among the costliest and deadliest substance use disorders (SUDs) world-wide and is frequently comorbid with other mental health conditions. There is no empirically validated medical treatment for MUD. Drug craving is the signature aspect of MUD and other substance use disorders and has been associated with continued drug use and relapse. The investigators and others have shown that transcranial direct current stimulation (tDCS) over dorsolateral prefrontal cortex (DLPFC) can modulate drug craving in different SUDs. tDCS is a method of non-invasive brain stimulation and is a low-cost scalable technology without any serious side effects that delivers low levels of direct current (0.1-2 mAmp) transcranially. However, there are significant inter-individual differences in response to tDCS, which is not well understood but can have profound impact on efficacy. Meanwhile, there are no studies with neuroimaging to show how tDCS affects drug craving. Investigators propose the first combined tDCS/functional Magnetic Resonance Imaging (fMRI) study to examine the acute effects of tDCS on neural substrates underlying drug induced craving.
This is a double-blind, placebo-controlled, randomized clinical trial evaluating the efficacy of extended-release naltrexone plus bupropion as a combination pharmacotherapy for methamphetamine use disorder. Participants will be randomly assigned to the active medication combination (AMC) group or matching placebo group and will receive medications over the course of 12 weeks. Follow-ups will occur in weeks 13 and 16.
The aim of this 2-stage, 3-site study is to investigate the effectiveness and safety of a combination of extended-release depot naltrexone plus extended-release bupropion as a potential pharmacotherapy for methamphetamine (MA) use disorder.

This is a double-blind, placebo-controlled phase 2b trial in which 54 MSM who use meth will be randomly assigned (2:1) to receive 12 weeks of as-needed intermittent oral naltrexone 50 mg enhanced with an EMA-informed EMI platform, or receive as-needed placebo with EMA-informed EMI. The 12-week treatment period is consistent with other pharmacotherapy trials for substance use disorders. The proposed sample size is also consistent with other phase 2b trials for substance use treatment. Upon enrollment, participants will complete daily EMA assessments and weekly visits for behavioral surveys and urine testing for meth metabolites, study drug dispensing and computer-based counseling for substance use. Safety laboratory assessments and vital signs will be completed monthly. Efficacy (Specific Aims 1-3) will be assessed upon trial completion as measured by proportion meth-positive urine samples; PrEP and ART adherence by drug levels and viral load testing; and sexual risk behavior data accounting for PrEP use and viral suppression.
This is a drug-drug interaction (DDI) study of mirtazapine for methamphetamine (MA) use disorder (MUD) to ensure the safety of this medication in the presence of a relevant dose of MA for people actively-using MA. Aim 1: To determine if mirtazapine alters the cardiovascular response to IV MA. Aim 2: To determine if the pharmacokinetics of IV MA are altered by mirtazapine administration. Aim 3: To evaluate the above aims in the setting of concomitant administration of methadone. This study involves two simultaneous within-subject drug-drug interaction studies, each comprised of 12 participants. A total of 24 subjects will be enrolled who have methamphetamine use disorder who will be classified into 2 groups: (Group 1: no opioids; Group 2: opioid use disorder on methadone maintenance). Subjects will be randomized to the order of mirtazapine and placebo (i.e. one-half will receive mirtazapine first, then placebo; one-half will receive placebo first, then mirtazapine).
This study will evaluate the behavioral effects of methamphetamine during maintenance on placebo, duloxetine, methylphenidate and duloxetine combined with methylphenidate using sophisticated human laboratory methods.
This is the first study of pomaglumetad in humans using methamphetamine. The goal of the study is to determine if pomaglumetad is safe when administered with methamphetamine. If shown to be safe with methamphetamine in the current study, a phase 2 clinical trial of pomaglumetad would be done to begin to find out if pomaglumetad is effective in treating methamphetamine use disorder.
Methamphetamine dependence is a significant drug use disorder in the Midwest. While a number of psychosocial and pharmacological treatments have been studied, no specific treatments for methamphetamine have been identified. This study is a collaborative pre-clinical and clinical partnership examining bupropion in the treatment of methamphetamine dependence.
This clinical trial is to implement contingency management (CM) as an intervention tool to address methamphetamine use and will be initiated during inpatient acute hospitalization in trauma injured patients. The goals are: * Gather effectiveness data on a CM program for participants in Hawaii who use methamphetamine during hospitalization and following discharge due to trauma injury * To assess participant perspectives on engaging with a CM program based at a Level 1 Trauma Center. Researches will assess both patient-reported and biologically-confirmed medium-term program effectiveness and conduct qualitative interviews with participants post-program. * To assess the rate of leaving against medical advice (AMA) and treatment completion in acute hospital setting in participants. * To assess the optimal timing of CM initiation for traumatically injured hospitalized patients by comparing patient outcomes (i.e. duration of CM participation and rates of CM program completion and providing negative urine samples) to NCT06532370 where CM was initiated after discharge from the hospital. For total of 12 weeks, participants will: * Be visited on Mondays, Wednesdays and Fridays by the research team to complete urine analysis during the hospitalization * Visit a follow up clinic up to 3 times per week on Mondays, Wednesdays and Fridays to complete urinalysis following discharge from the hospital * Complete Treatment Effectiveness Assessments at 6 and 12 weeks * Engage in qualitative interview at the end of the CM program
