Methamphetamines clinical trials at UC Health
6 in progress, 3 open to eligible people
open to eligible males
This study is a single-arm, non-randomized pilot study. Eligible participants are newly enrolled participants in an outpatient methamphetamine treatment program, and study activities will take place contemporaneously with participation in the service program. During the first two weeks of the treatment program, participants will be offered the chance to enroll in a low-intensity, internet-based depression intervention called MoodGym. Participants that agree to enroll will be offered the chance to attend up to seven MoodGym sessions at the same time they undergo outpatient methamphetamine treatment. It is hypothesized that sexual risk outcomes, as well as medication adherence (e.g., PrEP/PEP; ART) outcomes will be optimized for participants who enroll to receive the MoodGym intervention content.
open to eligible people ages 18-65
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.
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.

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.

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.

The most commonly used illicit stimulant in HIV-infected individuals is methamphetamine (MA). Prior studies demonstrate strong evidence that MA promotes increased HIV transcription as well as immune dysregulation. A challenge in achieving worldwide HIV eradication is targeting specific marginalized populations who are most likely to benefit from an HIV cure but possess poorer immune responses. For this study, HIV+ infected ART-suppressed individuals with no prior history of MA use disorder will be administered oral methamphetamine (the maximum FDA approved daily dose for the treatment of childhood obesity) to determine the effects of short-term MA exposure on residual virus production, gene expression, and inflammation. Measures of MA exposure in urine and serum will then be associated with residual virus production, gene expression, cell surface immune marker protein expression, and systemic markers of inflammation. The clinical trial data will generate advanced gene expression and immunologic data to identify potential novel targets for reversing HIV latency, reducing inflammation, and personalizing future therapies in HIV+ individuals who use MA.
