Methamphetamines clinical trials at UC Health
5 in progress, 2 open to new patients

  • Accelerated Development of Additive Pharmacotherapy Treatment (ADAPT-2) for Methamphetamine Use Disorder

    open to eligible people ages 18-65

    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.

  • Study of Pomaglumetad and Methamphetamine

    open to eligible people ages 18-55

    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.

  • Behavioral Therapy Development for Methamphetamine Abusers

    Sorry, currently not accepting new patients, but might later

    The purpose of this study is...to assess whether placing a substance abuse intervention for HIV+ methamphetamine users within an HIV medical care setting improves rates of follow-up on referral to treatment by primary care physicians; reduces drug use and sexual risk behaviors more than treatment-as-usual; and increases rates of adherence to HIV medication regimens.

  • Dopamine D2/D3 Receptor Upregulation by Varenicline in Methamphetamine Users

    Sorry, accepting new patients by invitation only

    While deficits in dopamine D2-type receptor availability have been linked to substance use disorders, higher availability associates with better behavioral treatment outcomes for stimulant dependence and resilience to addiction. Varenicline has been shown to upregulate D2-type receptors in drug-naive rats, and could be a useful therapeutic approach for the treatment of addictive disorders in humans. The purpose of the study is to assess the relationship between varenicline, dopamine signaling (specifically, D2-type receptor availability), functional connectivity within corticostriatal circuitry, genetic markers associated with smoking and methamphetamine abuse, and measures of cognitive performance. The investigators hypothesize that varenicline but not placebo will upregulate (increase) striatal dopamine D2-type receptor availability and improve cognition, and that the change in availability will correlate with the change in cognition. The investigators also hypothesize that varenicline but not placebo treatment will repair dysregulated connectivity between the striatum and prefrontal cortex observed in methamphetamine users, and will correlate with the change in cognition. The study design consists of two positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) scans to measure dopamine D2-type receptor availability and functional connectivity between the prefrontal cortex and striatum, two cognitive testing sessions including a battery of tests assessing working memory, declarative memory, sustained attention, inhibitory control, and reward-based decision making. Following eligibility screening, thirty six methamphetamine users will be enrolled and tested/scanned once prior to initiation of varenicline or placebo treatment and then again after completion of treatment.

  • Exercise in Methamphetamine Use Disorder Upregulation and Neural Function

    Sorry, not yet accepting patients

    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.
