Semaglutide for Treatment of People With Methamphetamine Use Disorder: the SHIFT Study

Methamphetamine use disorder is a major public health concern in Australia and globally. GLP-1 medications such as semaglutide (e.g. Ozempic) are approved for diabetes and medication, and may potentially affect craving for other substances apart from food. We do not know if this will help people who use methamphetamine ('ice') to reduce their use. This study will treat people who use methamphetamine with weekly injections of semaglutide. It will provide data on if this is a potentially safe and practical treatment for this group of people.

LDART for Stimulant Use Disorder

The goal of this study is to evaluate the feasibility, acceptability, and preliminary efficacy of a digital intervention called LDART in adults with stimulant use disorder.

Implementing a Contingency Management Program Addressing Methamphetamine Use For and With the People of Hawaii

The goal of this clinical trial is to use contingency management (CM) as an intervention tool to address methamphetamine use. The main objectives are to: * Gather effectiveness data on a pilot a CM program for participants in Hawaii who use methamphetamine following hospitalization due to traumatic 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. Participants will: * Visit a follow-up clinic up to three times per week to complete urinalysis following discharge from the trauma unit * Complete Treatment Effectiveness Assessments at 6 and 12-weeks * Engage in a qualitative interview at the end of the CM program

ECG Findings in Methamphetamine Use

This prospective cohort study aims to examine and compare electrocardiogram (ECG) parameters in subjects diagnosed with Methamphetamine Use Disorder (MUD) and Methamphetamine-Induced Psychotic Disorder (MP) during inpatient psychiatric treatment. ECG findings at hospital admission and during remission prior to discharge will be evaluated and compared between groups. The study also aims to determine whether methamphetamine-induced psychosis is associated with greater ECG abnormalities and increased cardiac risk compared to methamphetamine use without psychosis.

A Pilot Study of Transcranial Magnetic Stimulation Plus Episodic Future Thinking for Methamphetamine Use Disorder

The purpose of this study is to assess impact of repetitive transcranial magnetic stimulation (rTMS)+Episodic Future Thinking (EFT) vs. sham rTMS+EFT on delay discounting and methamphetamine (MA) demand, on vividness of future positive events during EFT training and on frequency of episodic thinking during the week following EFT training

LRFN5 and OLFM4 in Methamphetamine-Induced Psychosis

This cross-sectional observational case-control study aimed to examined serum levels of leucine-rich repeat and fibronectin type III domain-containing protein 5 (LRFN5) and olfactomedin-4 (OLFM4) levels in methamphetamine use disorder (MUD), methamphetamine-induced psychotic disorder (MP), and healthy control (HC) groups. The study also aimed to assessed systemic inflammation using the Aggregate Index of Systemic Inflammation (AISI) and examined associations between biomarkers and clinical symptom severity, including Insight Assessment Scale (IAS) and Positive and Negative Syndrome Scale (PANSS) scores.

Feasibility of Long-term, High-dose Stimulant for Methamphetamine Use Disorder

Methamphetamine use disorder (MUD) is becoming an increasing public health concern in Canada. While the evidence on the efficacy and safety of prescription psychostimulants for the treatment of MUD is promising, the knowledge on the maintenance therapy using stimulant agonist therapy is scarce and needs further investigation, especially in terms of long-term retention in treatment. The goal of this clinical trial is to evaluate the feasibility of a long-term (25 weeks) administration of high-dose stimulant agonist therapy, using Lisdexamfetamine (LDX-01) on top of treatment-as-usual (TAU), in a population of people with moderate to severe MUD, as measured by study retention, treatment retention, treatment adherence and satisfaction compared against a placebo group. Participants will be placed randomly into one of two groups: 1. TAU and high-dose LDX-01 2. TAU and placebo

Non-Abstinence Outcomes in Methamphetamine Use Disorder

Reduced drug use is a clinically meaningful target for treatment development, but few studies have evaluated the positive impacts produced by this behavioral change, preventing adoption of this endpoint in clinical trials. The proposed research will fill that critical knowledge gap by demonstrating the biopsychosocial benefits of reduced methamphetamine use. These data will be used to change current accepted methamphetamine treatment endpoints and accelerate identification of therapies for methamphetamine use disorder.

Methamphetamine and Troriluzole

This will be a human laboratory study evaluating the influence of troriluzole treatment on the effects of methamphetamine. Supported by and included in the Helping to End Addiction Long-term® (HEAL) Initiative.

Study of the Safety and Feasibility of Psilocybin in Adults With Methamphetamine Use Disorder

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/Thursdays or Tuesdays/Fridays by the research team to complete urine analysis during the hospitalization * Visit a follow up clinic up to 2 times per week on Mondays/Thursdays or Tuesdays/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

CHAMPION: Combining HIV And Meth Prevention and Treatment Interventions Optimized for HIV-Negative MSM

The goal of this randomized controlled trial is to pilot test new mobile health (mHealth) interventions to improve PrEP adherence among HIV-negative men who have sex with men (MSM) with mild to moderate methamphetamine use disorder (MUD). The CHAMPION intervention combines two mHealth tools-PrEPAPP and CBT4CBT-to address both HIV prevention and MUD treatment needs in this population. The study's specific aims are: * To evaluate the feasibility and acceptability of the CHAMPION intervention based on treatment retention and engagement rates. * To examine the preliminary efficacy the CHAMPION intervention to improve PrEP adherence, as measured by dried blood spot (DBS) tests compared to the waitlist control group.

Methamphetamine Use Disorder Support in Heart Failure Pilot Study

Heart failure (HF) affects over 6 million people in the US and is a major cause of both hospital admissions and death. HF has many causes and contributing factors. One of the most aggressive forms of HF is associated with methamphetamine abuse, which has become its own epidemic in the US over the past twenty years. People who use methamphetamine tend to develop HF at a much younger age, with more severe disease and more serious consequences. A recent analysis using nationwide data, methamphetamine use doubled the risk of death or hospitalizations compared to non-users in patients with HF. Thus, methamphetamine users with HF represent a very high-risk group of patients from a healthcare perspective. HF may be reversible in some patients who use methamphetamine if patients can achieve 1) abstain from further methamphetamine use and 2) consistently take all the medications that can improve HF. These two goals are very difficult to achieve in practice, as the care of both methamphetamine addiction and HF requires specialized medical expertise and intensive regular follow up of patients. In general, achievement of one goal is not possible without the other. Patients who use methamphetamine have poor adherence to medical follow-up and therapies, and abstinence from methamphetamine is difficult to maintain. This is further complicated because the current model of HF care does not incorporate treatment for methamphetamine use. The current study proposes to launch a multidisciplinary clinic that treats both HF and methamphetamine use disorder at the same time. The HF care will be led by a cardiologist while the methamphetamine use treatment will be led by a psychiatric clinical pharmacist trained in addiction medicine. State-of-the-art HF care will include optimization of four pillar HF medications. Methamphetamine use treatment will include counseling and incentivized abstinence known as contingency management (CM). The investigators will manage the patients in the clinic for 6 months total. The investigators are interested in demonstrating that this integrated clinic model will result in improved delivery of care for these patients by reporting the rates of successful abstinence from methamphetamine, improved optimization of the four HF medications, and enhanced patient reported quality of life over the 6 months of follow up. The investigators will also collect data on the costs associated with providing this level of care and estimate a range of potential cost-savings.

Psilocybin for Methamphetamine Addiction

The primary purpose of this study is to preliminarily determine if the use of psilocybin to promote abstinence from methamphetamine is feasible and well tolerated in populations such as those found in Northern Louisiana. Investigators will assess the impact of psilocybin-facilitated treatment on methamphetamine abstinence, craving, negative affect, cognitive function and quality of life. Components of the psilocybin experience will also be measured (persisting effects, quality of life, challenging experiences, etc). Investigators will assess feasibility and tolerability as rates of retention and challenging experiences, among other factors.

Testing an Accelerated TMS Protocol for Methamphetamine Use Disorder

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.

Deep TMS of Neural Circuits Associated With Stimulant Use Disorder

This study aims to evaluate the efficacy of deep transcranial magnetic stimulation (dTMS) as a treatment for Veterans with a methamphetamine use disorder (MUD).

Screen, Treat and Retain People With Primary Meth Use Disorder at MMT Clinics

This study is built upon the STAR-OM study (R01 DA050486) to assess if providing psycho-behavioral interventions and medications for people with primary methamphetamine use disorder (MUD) and without opioid use disorder (OUD) at methadone clinics is feasible and acceptable. In Vietnam and many U.S. settings, clinics providing medication for OUD (especially methadone clinics) are the only viable option for evidence-based addiction treatment. Importantly, many of these clinics are at primary care level and therefore accessible to people with primary MUD, who are in dire need for effective treatment. Furthermore, providers in methadone clinics are capable of conducting psycho-behavioral interventions, which remain the first line of treatment for MUD, and prescribing medications should these medications become available and approved by authorities. It remains unknown, however, if methadone clinics could serve as treatment facilities for those with primary MUD. This Supplement to the STAR-OM study will 1) assess the feasibility and acceptability of three recruitment strategies to enroll people with MUD and without OUD in MUD treatment at methadone clinics and 2) explore the feasibility and acceptability of providing psycho-behavioral interventions as well as challenges in providing medications at methadone clinics for people with MUD and without OUD. In Aim 1, the study will screen 600 people with primary MUD recruited through three strategies (peer outreach, snowballing and social media) over 3 months to enroll 60 people with MUD and without OUD into the study interventions. Participants will be screened at MMT clinics for meth use and readiness for MUD intervention. The study team will monitor recruitment rate for each strategy to assess feasibility. Acceptability will be assessed through focus group discussions with people who support recruitment (N=2 focus group with 12-16 participants), in-depth interviews with individuals eligible for enrollment and agree or decline to participate in the study interventions (N=15, 5 per recruitment strategy). In Aim 2, consenting participants will be randomized 1:1:1 into three arms of interventions over 12 weeks: (1) contingency management only; (2) group-based Matrix plus contingency management; and (3) individual-based Matrix plus contingency management. All participants will be required to provide urine samples randomly once a week. The investigators will monitor participation and retention rate in each treatment arm and completion of urine drug screens to assess feasibility. Acceptability will be assessed through post-intervention in-depth interviews with 15 participants, focus groups with methadone providers who deliver behavioral interventions (N = 1 focus group with 6-8 participants), and in-depth interviews with policy makers at national and city levels (N=5). In addition, participants will be asked in these interviews and focus groups about the challenges and facilitators of providing medications for treatment of MUD at MMT clinics should they become available. Findings from this Supplement will be used to prepare for a larger trial to assess effectiveness of implementing psycho-behavioral interventions for people with primary MUD and without OUD at methadone clinics.

Methamphetamine Cue-reactivity

In this observational cohort study, the researchers propose to first identify a psychophysiological marker of methamphetamine cue-reactivity and its incubation with abstinence from methamphetamine use (MUD) and examine group-differences between men who have sex with men (MSM) and non-MSM MUD. The primary objective is to identify psychophysiological markers of methamphetamine (MA) cue-reactivity and its abstinence incubation. The secondary objective is to examine group-differences in methamphetamine use disorder (MUD) individuals between homosexual men (MSM) and heterosexual men (non-MSM). The primary endpoint is to assess incubation of cue-reactivity longitudinally with its reduction in cognitive reappraisal, and the secondary endpoint is to examine the impact of cognitive reappraisal on clinical outcomes of methamphetamine use disorder (MUD) in homosexual men (MSM). 2-year long study. Screening and enrollment will be done at different locations of the Addiction Institute of Mount Sinai. The EEG session will be done at Icahn School of Medicine at Mount Sinai. Participation in the research study will be for a single EEG session.

Tirzepatide for Obesity and Meth Use Disorder

This is an open-label pilot study to evaluate the feasibility and preliminary efficacy of using tirzepatide when prescribed for its United States (US) Food and Drug Administration (FDA)-approved weight-related indication in individuals with comorbid methamphetamine use disorder.

Deep Brain Stimulation (DBS) for Methamphetamine Use Disorder

We will evaluate the effects of deep brain stimulation (DBS) of bilateral nucleus accumbens (NAc) added to background treatment for treatment refractory Methamphetamine Use Disorder (MUD). This is a small randomized cross-over study to demonstrate feasibility and safety, test treatment outcomes (use, craving), and identify novel biological targets (NAc local field potentials (LFP) and functional MRI).

Ketamine-Assisted Recovery for Methamphetamine Use Disorder & HIV

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

TACS Intervention for Methamphetamine Addiction

In 2021, nearly 296 million people worldwide used psychoactive substances, highlighting a significant need for effective interventions for disorders such as Methamphetamine Use Disorder (MUD). Despite existing treatments, including behavioral therapies and medications, the relapse rates remain high, signaling the need for more potent and targeted approaches. This clinical trial investigates high-intensity transcranial alternating current stimulation (Hi-tACS), a non-invasive method that applies 15mA electrical currents with a patented frequency of 77.5Hz to modulate brain activity. Hi-tACS has shown promise in preliminary studies for its ability to reduce drug cravings significantly by influencing brain regions crucial in addiction. The primary aim of this study is to evaluate the effectiveness of Hi-tACS in curbing cravings in individuals with MUD. As secondary objectives, the trial will also explore the potential benefits of Hi-tACS in alleviating other clinical symptoms, enhancing cognitive performance, and positively influencing brain activity. This study seeks to establish Hi-tACS as a more effective treatment option that could lead to substantially lower relapse rates for individuals with MUD.
