Active clinical trials for "Cocaine-Related Disorders"

The purpose of this study is to determine the density of DA transporters during prolonged cocaine abuse and during withdrawal from cocaine use. This aim will test the hypothesis that DA transporters are altered by cocaine abuse and reestablished during withdrawal.

The purpose of this challenge grant is to conduct an initial test of a new, enhanced version of this protocol (telephone monitoring and counseling - enhanced, or TMAC-E), which has been modified to include the elements of our existing continuing care intervention plus patient-centered changes to boost patient involvement and community linkages. The investigators will recruit 150 cocaine dependent patients in publicly funded, community-based programs and randomize them to treatment as usual or the TMAC-E and follow them for 12 months.

The objective of this 26-28 week study is to demonstrate that the rate of cocaine dependent subjects treated with CPP-109 vigabatrin in addition to counseling, who completely stop use of cocaine in the last 2 weeks of the study's Treatment Phase (Weeks 8 and 9) will be higher than seen in subjects treated with placebo in addition to counseling.

The purpose of this study is to assess selegiline as a pharmacotherapy for cocaine dependence.

The purpose of this study is to test antidepressant medication, gepirone, as a pharmacotherapy for cocaine dependent subjects.

The purpose of this study is to evaluate naltrexone as an adjunct in alcoholic cocaine dependent patients; concurrent relapse prevention theory.

The pharmacokinetics of 10 to 12 individuals receiving 60 mg of sustained release dexamphetamine will be studied. These individuals have received this medication before in a previous trial where the pharmacodynamics were investigated. This trial will last 5 consecutive days during which blood samples will be drawn for pharmacokinetics analyses. Dried blood spots will also be collected for the clinical validation of the bioanalytical method wherein these are used.

The purpose of this study is to evaluate treatments designed to improve cocaine treatment success by combining medications that target cocaine-related cognitive impairments.

This protocol (a supplement to 805466) is to test whether our telephone continuing care model can be implemented successfully by "real world" publicly funded programs. Participants will be recruited from Philadelphia's Department of Behavioral Health - run drug programs. The investigators will train city telephone care managers to deliver our telephone continuing care intervention to patients in this program. The investigators will randomize 200 to receive this intervention or usual care and follow them for 12 months.

For this project, the investigators are interested in exploring a new way to extend and maintain drug abstinence in people who are addicted to crack cocaine. This study will combine a medication called D-Cycloserine (DCS) and weekly cognitive behavioral therapy (CBT) to assess whether the combination will enhance people's ability to stay clean (drug free) for longer periods of time. One of the greatest risks for drug relapse is drug craving. Oftentimes drug craving occurs when a person is confronted with stressors and reminders of past drug use behavior. DCS has been shown to enhance the learning of new information. By administering DCS prior to learning new techniques such as how to cope with drug craving and drug-use reminders, it is possible that patients can be more successful at living a drug free life for a longer period of time. In addition to exploring this model behaviorally, the investigators will explore changes that may occur in the brain before and after the therapy/medication intervention. A technique called MRI (Magnetic Resonance Imaging) will be used to identify areas of the brain that are being activated during an attention task. Areas of neural activation will be assessed at study entry, end of therapy (4-week endpoint) and one month following completion of the treatment program.
