Active clinical trials for "Cocaine-Related Disorders"

To examine the clinical efficacy of sertraline (200 mg/day) alone or sertraline in combination with gabapentin. The purpose of this study is to examine whether the antidepressant sertraline alone or combined with gabapentin delays time to relapse relative to placebo in recently abstinent cocaine-dependent volunteers who are also depressed. In addition, whether depressive symptoms or genetic factors influence treatment response to the study medications will be examined. Our hypothesis is that those on combined sertraline-gabapentin will show a longer period of abstinence than those on sertraline alone or placebo.

Cocaine dependence is a major public health problem and the development of a treatment for this disorder is a priority. To date, treatment interventions based on positive incentive principles have shown the strongest effects for improving substance use outcomes. One such example is contingency management (CM) interventions in which nondrug rewards are used to compete with cocaine. Recent evidence suggests that certain medications improve response to CM interventions, particularly agents that target dopamine reward systems in the brain. A promising dopamine-enhancing medication is levodopa. The study team has observed the strongest effects of levodopa when the medication is administered in the context of CM therapy, perhaps through mechanisms that enhance reward saliency. The proposed study is designed to further evaluate this promising treatment approach. Cocaine dependent outpatients will participate in a randomized, 2-group (levodopa vs. placebo), double-blind clinical trial. CM will be behavioral therapy platform for both treatment groups. The study will test the primary hypothesis that CM+levodopa will be more effective than CM+placebo in reducing cocaine use. This study is expected to validate the usefulness of a new behavioral-pharmacological treatment approach for cocaine dependence.

This placebo-controlled trial will test the effectiveness of Seroquel XR™ for the treatment of cocaine dependence in non-psychotic individuals who are cocaine dependent.

This is an outpatient clinical trial of topiramate for addressing cocaine dependence and reduction of cocaine associated behaviors in opiate dependent drug users maintained on methadone treatment. The study aims to answer whether topiramate is safe and acceptable to methadone patients reduces cocaine use helps with collateral problems such as alcohol abuse, tobacco dependence, anxiety, PTSD and/or pain symptoms. The study will also evaluate topiramate effect on neuro-cognitive performance.

The purpose of this study is to develop a model for long-term maintenance of behavior change by examining the effects of extending the duration of contingency management (CM) for drug abuse on long-term abstinence outcomes. The primary hypothesis is that the Extended (36 week) CM group will have better long-term outcomes as exhibited by greater rates of abstinence at each follow-up assessment as compared to the Standard (12 week) CM group.

The purpose of this study is to determine if quetiapine add-on therapy is associated with a decrease in cocaine use and craving and a greater improvement in mood.

The purpose of this study is... To assess whether a behavioral treatment that combines motivational enhancement and cognitive skills training therapy (MET-CBT) is more effective than brief advice in: 1) decreasing use of a full range of psychoactive substances (e.g. marijuana, cocaine, methamphetamines, alcohol, nicotine, opioids) in pregnant substance using and dependent women; 2) decreasing HIV risk behavior; 3) improving birth outcomes (longer gestations and greater birth weight).

Primary objective #1: Determine the relative effectiveness of MI-IOP and MI-PC in the full study sample with regard to treatment engagement over weeks 1-12 and cocaine/alcohol use over weeks 1-24. Hypothesis 1: An intervention that explores several possible treatment options with the patient and provides the chosen option (e.g., MI-PC) will produce higher rates of treatment engagement than an intervention focused on engagement in IOP only (e.g., MI-IOP). Hypothesis 2: An intervention that explores several possible treatment options with the patient and provides the chosen option (e.g., MI-PC) will produce better cocaine/alcohol use outcomes than an intervention focused on engagement in IOP only (MI-IOP). Secondary analysis 1: Among the Non-engaged patients, determine rates of selection of each of the three options in MI-PC, retention rates within each option, and cocaine/alcohol use outcomes in each option. Secondary analysis 2: Among the Engaged patients, determine rates of selection of each of the three options in MI-PC, retention rates within each option, and cocaine/alcohol use outcomes in each option. Primary objective #2: Determine whether the relative effectiveness of MI-IOP and MI-PC varies as a function of engagement group, with regard to treatment engagement over weeks 1-12 and cocaine/alcohol use outcomes over weeks 1-24. Hypothesis 1: The predicted main effect on retention favoring MI-PC over MI-IOP will be significantly larger among patients in the Non-engaged group than among those in the Engaged group. Hypothesis 2: The predicted main effect on cocaine/alcohol use outcomes favoring MI-PC over MI-IOP will be significantly larger among patients in the Non-engaged group than among those in the Engaged group.

The purpose of this study is to determine whether varenicline (Chantix), is effective for the treatment of cocaine dependence.

We are testing to see if Galantamine, a learning enhancing medication, will help methadone maintained cocaine abusers with their learning and memory specific to CBT using an innovative CBT computer program.
