Filter by:The purpose of Project 2 is to execute phase I functional magnetic resonance imaging (fMRI) studies to assess the effects of lorcaserin on brain target engagement (measured by fMRI brain activation and neural connectivity) in cocaine use disorder (CocUD) subjects and/or opioid use disorder.
The purpose of this study is to evaluate whether prednisolone lowers intensity and frequency of craving in heroin-addicted subjects undertaking a detoxification of cocaine and/or heroin.
Studies using positron emission tomography (PET) have been used with great success in demonstrating specific abnormalities in several facets of dopaminergic system function in human populations (Narendran and Martinez 2009). Among the first, most consistent, and broadly replicated of such findings in drug- (including cocaine) dependent individuals has been the reduction in subcortical (striatal) D2/3 receptors as imaged, most commonly, by the reversible, non-selective, D2/3 receptor antagonist radiotracer, [11C]raclopride. Certain dissociations on D2/3 availability by radioligand ([11C]raclopride vs. [11C]PHNO) and by brain region (striatum vs. SN; terminal vs. somatodendritic, respectively) are poorly understood in relationship to prior antagonist tracer results. In the current study the investigators will use pharmacological interventions (AMPT and methylphenidate) with both antagonist and agonist radiotracers to experimentally reconcile these discordant findings and clarify potential mechanistic inter-relationships.
We will develop a procedure for conditioning cue-cocaine associations in human drug users. Next, we will reactivate that learning and intervene pharmacologically to prevent the reconsolidation of cue-drug memories. We hypothesize that a combined behavioral and pharmacological approach will have significant potential for persistently inhibiting relapse.
The purpose of this study is to see if a drug called Candesartan will help to reduce use of cocaine.
This project will evaluate the effect of a single sub-anesthetic dose of ketamine on the time to first cocaine use and abstinence rates in 60 treatment-seeking cocaine-dependent individuals receiving mindfulness-based relapse prevention (MBRP) therapy, using a 5 week combined laboratory-inpatient and outpatient double-blind, randomized, controlled trial.
The purpose of this study is to evaluate ideal dose or lisdexamfetamine and tolerability, plus reduction in cocaine use and craving.
This is the first study to be conducted in humans for JDTic, a new chemical entity, with evaluations focusing on the safety, tolerability, and pharmacokinetics (PK) of JDTic following administration of single oral doses. JDTic is a novel, selective κ opioid receptor antagonist and is currently being developed by RTI International as a potential pharmacotherapy to treat cocaine dependence. This study has the possibility of identifying the maximum tolerated dose in humans and a surrogate measure of JDTic pharmacodynamic (PD) activity. Data from this study will be used to plan for and define dose ranges for subsequent studies, as well as to identify potential indicators of JDTic pharmacological activity.
The purpose of this study is to evaluate the effectiveness of vigabatrin at reducing drug and alcohol use in individuals addicted to cocaine and alcohol. Vigabatrin is approved for the treatment of seizures. It has not been proven to be effective for the treatment of alcohol or cocaine dependence.
The purpose of this study is to assess potential interactions between intravenous (IV) cocaine and treatment with lofexidine.
