All Clinical Trials for DESOXYN

Trial ID Title Status Sponsor Phase Start Date Summary
NCT01967381 ↗ Targeting GABA and Opioid Systems for a Pharmacotherapy for Methamphetamine Abuse Completed National Institute on Drug Abuse (NIDA) Early Phase 1 2013-10-01 The research proposed in this application will determine the initial efficacy, safety and tolerability of a novel drug combination, oxazepam (Serax®) and naltrexone (Revia®), as a pharmacotherapy for methamphetamine (Desoxyn®) dependence. A rigorous, inpatient human laboratory study will be conducted. The proposed study is innovative and important because it will provide the impetus for the conduct of double blind, placebo-controlled trials to further demonstrate the efficacy of combined oxazepam and naltrexone for managing methamphetamine dependence.
NCT01967381 ↗ Targeting GABA and Opioid Systems for a Pharmacotherapy for Methamphetamine Abuse Completed University of Kentucky Early Phase 1 2013-10-01 The research proposed in this application will determine the initial efficacy, safety and tolerability of a novel drug combination, oxazepam (Serax®) and naltrexone (Revia®), as a pharmacotherapy for methamphetamine (Desoxyn®) dependence. A rigorous, inpatient human laboratory study will be conducted. The proposed study is innovative and important because it will provide the impetus for the conduct of double blind, placebo-controlled trials to further demonstrate the efficacy of combined oxazepam and naltrexone for managing methamphetamine dependence.
NCT02058966 ↗ Pilot Study of Entacapone for Methamphetamine Abuse Completed Portland VA Medical Center Early Phase 1 2014-06-01 Addiction to methamphetamine is a serious health problem. There are no medications that a doctor can give someone to help them stop using methamphetamine. Entacapone (Comtan©) is a medication that could help people addicted to methamphetamine. This study will see how entacapone works in healthy people who are given methamphetamine. We think that the study drug will be well tolerated, and that it will prevent some of the effects of methamphetamine that make it so addictive. We also want to see how differences in people's genes may cause differences in the ways the study drug and methamphetamine work for them. The study has six total visits. The first visit is for screening. Tests and procedures will make sure it is safe for subjects to participate. The second visit is a familiarization day. Subjects will receive methamphetamine, but no entacapone. This is done to make sure they can tolerate the drug and recognize its effects before being given a second drug on the same day. Subjects will take surveys and computer tests to see how the medications change mood, thinking, and liking the drug. The final four visits are the actual study days. Subjects will be randomly assigned (like the flip of a coin) to the different ways to get either 1) study medication or placebo (placebo contains no active study medication) and then 2) methamphetamine or placebo. Subjects will be in all four groups during the study, which means that each day a subject will get a different group.
NCT02058966 ↗ Pilot Study of Entacapone for Methamphetamine Abuse Completed Oregon Health and Science University Early Phase 1 2014-06-01 Addiction to methamphetamine is a serious health problem.

NCT02323048 ↗ Acquisition of Responses to a Methamphetamine-associated Cue in Healthy Humans Completed University of Chicago N/A 2014-07-01 The aim of the study is to extend our investigations of drug-associated conditioning with healthy volunteers. The investigators have recently completed a pilot study demonstrating that subjects show an increase in self-reported preference for a visual stimulus paired with stimulant drug administration. Furthermore, our pilot data suggest that methamphetamine acts synergistically with rewards in the environment, such that this conditioning effect is facilitated by experiencing the drug in the presence of rewarding, or positive events, such as earning money. The investigators now aim to extend these findings by assessing not only self-reported preference, but also attentional and psychophysiological (electromyogram; EMG) responses to the drug-associated stimuli.
NCT03825536 ↗ Effect of Methamphetamine on Residual Latent HIV Disease Study Recruiting National Institute on Drug Abuse (NIDA) Phase 4 2021-01-01 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.
NCT03825536 ↗ Effect of Methamphetamine on Residual Latent HIV Disease Study Recruiting University of California, San Francisco Phase 4 2021-01-01 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.
