Safety, Tolerability, and Pharmacokinetics of Single, Escalating Oral Doses of RTI-336 in Healthy,...
Cocaine DependenceThis is the first study to be conducted in humans for RTI-336, a new chemical entity, with evaluations focusing on the safety, tolerability, and pharmacokinetics of RTI-336 following administration of single, oral doses. RTI-336 is a novel dopamine transporter inhibitor of the 3-phenyltropane class, and is currently being developed by RTI International as a potential pharmacotherapy to treat cocaine dependence. Data from this study will be used to plan and define dose ranges for subsequent studies.
Vigabatrin Ph 1 Cocaine Interaction Study
Cocaine AddictionThis is a Phase 1 safety/tolerably study to determine if there are clinically significant interactions between oral vigabatrin (gamma vinyl-gamma-amino butyric acid; VGB) concurrent with intravenous (IV) cocaine infusions.
Efficacy of Varenicline in Methadone-Stabilized Cocaine Users
Cocaine DependenceNicotine DependenceCocaine addiction continues to be an important public health problem in the US with a significant cost to the individual and society. Among substance abusers, cocaine use has been recognized as a significant problem especially in methadone-maintenance patients. In several studies, rates of cocaine use have been reported to range from 30 to over 60 percent of those in methadone maintenance programs (Condelli et al. 1991; Hunt et al. 1984; Kidorf and Stitzer 1993; Kosten et al. 1988). In these patients, cocaine use seems to be a predictor of poor clinical outcome (Hartel et al. 1995; Kosten et al. 1987a). The development of effective pharmacotherapies for cocaine use disorders, especially in the opioid-dependent population is of great importance. Unfortunately, such effective pharmacotherapies do not exist. To determine the safety and tolerability of varenicline in cocaine-using methadone-stabilized subjects. To determine if varenicline is efficacious in reducing cocaine-use in methadone-stabilized subjects.
A Pilot Study of Cabergoline for the Treatment of Cocaine Dependence
Cocaine DependenceCocaine Abuse2 moreThe purpose of this study is to determine the effects of treatment with cabergoline, compared to treatment with placebo, on cocaine induced craving and subjective effects in cocaine-dependent human volunteers.
The Effects of Doxazosin on the Cardiovascular and Subjective Effects of Cocaine
Cocaine AddictionCocaine Abuse2 moreThe purpose of the study is to asses the potential interactions between intravenous cocaine and doxazosin in cocaine dependent volunteers who are not seeking treatment. The study will evaluate the effects of doxazosin on the cardiovascular and subjective effects of cocaine in a human laboratory study.
Rivastigmine and Huperzine A as Treatments for Cocaine Dependence
Cocaine DependenceCocaine Addiction2 moreThe purpose of this study is to determine the safety and effects of rivastigmine and huperzine A (HupA), potential treatments for cocaine abuse, when used before experimental administration of cocaine, on a number of physical and psychological measures.
Benefits of Therapy With Virtual Reality Exposure in the Treatment of Cocaine Use Disorders
AddictionCocaine-Related DisordersCocaine addiction is a multifactorial disease with important consequences: somatic, psychiatric... The number of applications for treatment for cocaine addiction is gradually increasing from year to year but no conventional treatment is available. New tools such as virtual reality could be used in this treatment. We propose to create a virtual reality program based on the analysis of high-risk relapse situations described by patients. We will then assess the effect of this cybertherapy on patients' relapse time and their desire to use cocaine
A Double-Blind, Controlled Study of Aripiprazole in Co-Morbid Schizophrenia and Cocaine Dependence...
SchizophreniaCocaine DependenceThe purpose of this study is to gather systematic clinical data on whether aripiprazole, a partial dopamine agonist, beneficially affects schizophrenia plus cocaine dependence subjects. Since aripiprazole has established effects against schizophrenia, the study focuses on whether aripiprazole concurrently reduces co-morbid cocaine dependence in schizophrenia plus cocaine dependence sufferers compared to a standard typical antipsychotic treatment (perphenazine). The working hypothesis states that subjects in the aripiprazole treatment arm of the study will give fewer cocaine positive urine specimens as compared to the perphenazine control arm.
Pharmacotherapy for HIV+ Stimulant Dependent Individuals
HIV InfectionsCocaine DependenceThe hypotheses of this study are: Ondansetron will show a decrease in cocaine use from baseline in individuals with HIV who are cocaine using. Ondansetron will show a decrease in cravings from baseline in individuals with HIV who are cocaine using. After informed consent and screening, HIV infected individuals who are cocaine dependent and qualify for the study will be offered ondansetron 4mg BID for six weeks in an open label format 4mg BID has been found to have efficacy compared to placebo. At screening and then at each visit, they will be asked to provide urine and a drug of abuse screen will be conducted to assess for cocaine. They will be asked to detail their recent cocaine use in the last month and then will be given a visual analog scale to assess their craving for cocaine. They will be asked to return weekly for 6 weeks to receive a week's supply of ondansetron and to give a urine sample that will test for cocaine. They will fill out a time line follow back for the past week and asked to assess their craving for cocaine on a visual analog scale.
Assessment of Potential Interactions Between GBR 12909 and Cocaine - 1
Cocaine-Related DisordersThe purpose of this study is to assess potential interactions between intravenous (IV) cocaine and 3 doses of GBR 12909.
