Pharmaco-Magnetic Resonance Spectroscopy (MRS) Study of Clavulanic Acid
Cocaine DependenceA dose-escalation study to determine the optimum dose of Clavulanic Acid (CLAV) for effects on craving and efficacy.
Efficacy and Safety of TV-1380 as Treatment for Facilitation of Abstinence in Cocaine-Dependent...
Cocaine AddictionThe primary objective of this study is to assess the efficacy and safety of TV-1380 [Recombinant human serum albumin (HSA) mutated butyrylcholinesterase (AlbuBChE)] in facilitating abstinence in cocaine-dependent subjects.
Brain Function and Structure in Cocaine Dependence
Cocaine DependenceThe purpose of this study is to examine the role of brain MRI findings in predicting treatment outcomes among individuals with cocaine dependence.
A Phase II Trial of Varenicline for the Treatment of Cocaine Dependence
Cocaine DependenceThis is a double-blind placebo-controlled clinical trial (n = 156) of varenicline for the treatment of cocaine dependence that utilizes contingency management to promote treatment attendance.
Open-Label Pilot Study of Lisdexamfetamine for Cocaine Dependence
Cocaine DependenceThe proposed protocol is an open-label pilot study of the treatment of cocaine dependence using lisdexamfetamine (LDX), a prodrug of d-amphetamine. The investigators plan to enroll 12 patients in an eight-week open-label trial to obtain preliminary data regarding the safety, tolerability, and potential utility of lisdexamfetamine for treatment of cocaine dependence and to determine an effective dosage range.
Contingency Management Treatment for Crack Addiction - Study With Brazilian Population
Cocaine Related DisordersCrack addiction has become a severe health problem in Brazil. Today, crack addiction is the primary cause for inpatient treatment for all illicit substances. When compared to cocaine, crack users develop much faster diagnoses for crack dependence, shows a more compulsive pattern of use, has higher probability of living or have lived in the streets, and of engaging in illegal activities. Consequently to this, mortality of crack addicts is 7 times higher than for the rest of the population. Despite all efforts being made for the development of effective pharmacological treatments for stimulant addiction (crack included), up to today, there is no robust evidence of efficacy of any pharmacological treatment. For that reason, the use of evidence based psychosocial interventions is so important for treating this population. Although today open treatment facilities in Brazil are more and more starting to use evidence-based interventions such as motivational interviewing, cognitive behavior therapy, relapse prevention and coping skills, such treatments present very modest results when treating crack addiction. The biggest difficulties encountered when treating this population are maintaining patients in treatment, reducing crack use and achieving continued abstinence. A psychosocial treatment based in behavioral principals' named Contingency Management (CM) is widely applied in the USA. Recent meta-analyses and review studies present robust evidence that, when applied alone or in adjunction with other psychosocial and pharmacological treatment, CM is the most effective treatment for what regards, treatment retention, reducing drug use and promoting continued abstinence. The purpose of this study is to evaluate if Contingence Management (CM) can be affective in the treatment of crack addiction in Brazil. To accomplish this, 60 individuals (male and female from 18 to 65 years of age) seeking open treatment for crack addiction will be randomized to 2 treatment conditions (Standard treatment (ST) or ST+CM. Both treatments will last 12 weeks with 3 and 6-month follow-up. In both groups patients will be encourage to leave urine samples 3 times week. Hypotheses: Patients receiving ST+CM will stay longer in treatment, have more negative tests for cocaine/crack, and achieve longer periods of cocaine/crack abstinence when compared to patients receiving ST alone.
Exercise as an Adjunctive Treatment for Cocaine Dependent Patients
Cocaine DependenceThe purpose of this study is to evaluate if exercise added to usual treatment improves cocaine dependence treatment. The primary objective of this study is to investigate if exercise can facilitate cocaine craving reduction. The secondary aims are to evaluate if exercise can reduce negative mood states, improve quality of life and facilitate abstinence of cocaine.
Smoking-Cessation and Stimulant Treatment (S-CAST)
Cocaine DependenceMethamphetamine Dependence1 moreThe primary objective of this study is to evaluate the impact of substance-abuse treatment as usual plus smoking-cessation treatment (TAU+SCT), relative to substance-abuse treatment as usual (TAU), on drug-abuse outcomes. Specifically, this study will evaluate whether concurrent smoking-cessation treatment improves, worsens, or has no effect on stimulant-use outcomes in smokers who are in outpatient substance-abuse treatment for cocaine or methamphetamine dependence.
Modafinil, Sleep Architecture and Cocaine Relapse
Cocaine DependenceThe medication modafinil has been shown to reduce cocaine use in some cocaine users. The investigators have shown that modafinil taken in the morning improves sleep in chronic cocaine users. The investigators hypothesize that the beneficial effects of modafinil in reducing cocaine use may be related to specific effects modafinil has on sleep. This study will measure sleep and cocaine use in cocaine dependent persons who are trying to stop using cocaine, and will test the connection between modafinil's effects on sleep and cocaine use.
Levetiracetam (Keppra) Tolerability in Cocaine Abusing Methadone-maintained Patients.
Cocaine DependenceOpioid DependenceThe proposed investigation will use methadone maintained patients who have concurrent cocaine dependence in order to take advantage of the excellent (over 80%) treatment retention in this patient group and to maximize treatment compliance by daily observed medication with both methadone and levetiracetam. In the initial patients we will explore the tolerability of escalating doses of levetiracetam as well as its potential role in reducing cocaine use, as monitored by self-report and verified by three-times weekly urine toxicology testing in methadone treated patients.The specific aim of this study is to evaluate the tolerability and efficacy of levetiracetam 3 grams/day in modifying cocaine-using behavior, reducing cocaine craving and attenuating cocaine's reinforcing effect among methadone-maintained patients
