NCT ID: NCT03025321 Not yet recruiting - Cocaine Addiction Clinical Trials

Effects of Repetitive tDCS on Relapse in Cocaine Addiction: EMA Study

Start date: January 2017
Phase: N/A
Study type: Interventional

Repetitive bilateral (left cathodal/ right anodal) transcranial Direct Current Stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) seems to reduce craving and relapse risk. However, little is known about the relapse rates in cocaine addiction after tDCS, despite the need for new treatment interventions to reduce the high relapse rates in cocaine addiction. The investigators aim to explore the effects of repetitive tDCS in a larger sample (N=80) of cocaine addicted patients on number of relapse days after three months. In addition, the underlying working mechanism will be explored (e.g. cognitive control functioning). Ecological momentary assessment (EMA) will be used to measure relapse, craving and mood since retrospective self-reports seem to be less reliable in this respect.

NCT ID: NCT03018236 Recruiting - Cocaine Addiction Clinical Trials

Effect of N-acetylcysteine on Alcohol and Cocaine Use Disorders: A Double-Blind Randomized Controlled Trial.

Start date: January 2017
Phase: Phase 4
Study type: Interventional

This study evaluates the use of N-acetylcysteine in the treatment of alcohol and cocaine use disorders. Alcohol users will be split in two groups, one will receive the active N-acetylcysteine and the other placebo. The same division will occur with cocaine users. The effects of N-acetylcysteine in adherence, abstinence, psychiatric symptoms and stress biomarkers will be evaluated.

NCT ID: NCT02939352 Completed - Alcoholism Clinical Trials

The Effects of Theta Burst Stimulation on the Brain Response to Drug and Alcohol Cues

addictionTBS
Start date: September 2014
Phase: Phase 1
Study type: Interventional

High relapse rates among substance dependent individuals are likely due to a combination of factors that involve limbic circuits in the brain involved in craving, including vulnerability to salient cues. Emerging data suggests that non-invasive, targeted brain stimulation may be able to modulate activity in these circuits and decrease craving. The primary goal of this pilot study is to determine the extent to which a single session of continuous theta burst stimulation (TBS) to the medial prefrontal cortex can attenuate limbic circuitry involved in craving among cocaine users and alcohol users. This will be tested through a double-blind,sham-controlled brain stimulation and brain imaging study in a cohort of polysubstance abusers and alcohol users.

NCT ID: NCT02892851 Recruiting - Cocaine Addiction Clinical Trials

Deep Brain Stimulation of the Sub-Thalamic Nucleus to Treat Severe and Treatment-resistant Cocaine Addiction.

STUC
Start date: March 2014
Phase: N/A
Study type: Interventional

Cocaine addiction is a chronic condition with severe cardiac, neurologic, psychiatric and social complications. Cocaine is the second most consumed illicit drug in France. Its prevalence has been multiplied by 3 between 2000 and 2008, and is still on the rise. Craving, the compulsive need to consume, is a key feature of cocaine addiction. It is also predictive of treatment efficacy. However, there is no validated treatment for severe cocaine dependence yet. Response to current psychological and medical treatment is poor, with 73% relapse after 3 months. Patients with severe cocaine addiction are thus in a therapeutic deadlock. To address these unmet medical needs, the investigators designed a pilot study (n=2) to evaluate the safety and the efficacy of the deep brain stimulation of the subthalamic nuclei (STN-DBS) in severe cocaine addiction with at least one cardiac, neurologic or psychiatric complication. Indeed, compulsivity is a critical component of craving, and severe treatment-resistant obsessive compulsive disorder (OCD) are already successfully treated using STN-DBS. Moreover, animal studies recently demonstrated a therapeutic effect of STN-DBS in rats addicted to cocaine. Together, these two lines of research suggest a therapeutic effect of STN-DBS in cocaine addiction mediated by an anti-obsessive mechanism on craving.

NCT ID: NCT02768441 Completed - Cocaine Addiction Clinical Trials

Dexamphetamine Sustained Release Pharmacokinetics and Clinical Validation of Dried Blood Spots

Start date: November 1, 2016
Phase: Early Phase 1
Study type: Interventional

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.

NCT ID: NCT02626494 Completed - Cocaine Addiction Clinical Trials

Neurobiological Adaptations and Pharmacological Interventions in Cocaine Addiction

CoGlu
Start date: March 2015
Phase: Phase 4
Study type: Interventional

This study aims at testing for the impact of glutamatergic changes on drug craving in cocaine addiction, and to evaluate the effects of n-acetylcysteine (n-AC) on both glutamate homeostasis and craving using a randomized, double-blind, placebo controlled cross-over design.

NCT ID: NCT02563769 Recruiting - Cocaine Dependence Clinical Trials

Clavulanic Acid (CLAV) and Cocaine Interaction Safety Study

Start date: February 2016
Phase: Phase 1
Study type: Interventional

The main purpose of this study is to determine if it is safe to use the study drug, clavulanic acid, in combination with cocaine. In this study, subjects will receive intravenous (i.v.) cocaine and the study drug, clavulanic acid. The safety of clavulanic acid is being studied so future studies can be done to find out if this drug is helpful in treating cocaine dependence. Currently, there is no available medication treatment for cocaine dependence.

NCT ID: NCT01984177 Completed - Clinical trials for Substance-Related Disorders

Effects of Corticorelin Administration on Dopamine Transmission, Craving, and Mood in Cocaine Dependence

Start date: June 2013
Phase: N/A
Study type: Observational

This study will, in a sample of cocaine-dependent and healthy control subjects, administer corticorelin and compare dopamine release between groups. Dopamine release will be measured using PET neuroimaging with the radiotracer [11C]-(+)-PHNO.

NCT ID: NCT01929343 Recruiting - Cocaine Addiction Clinical Trials

Lidocaine Infusion as a Treatment for Cocaine Relapse and Craving

LIDO
Start date: January 2014
Phase: Phase 2
Study type: Interventional

We propose that the systemic administration of lidocaine following the induction of cue-induced craving, relative to saline plus cue-induced craving or lidocaine without cue-induced craving, will block the reconsolidation of cue memories. This will lead to a reduction in cue-induced craving upon repeated testing as well as subsequent cocaine use and basal craving.

NCT ID: NCT01887366 Completed - Cocaine Addiction Clinical Trials

Efficacy and Safety of TV-1380 as Treatment for Facilitation of Abstinence in Cocaine-Dependent Subjects

Start date: June 2013
Phase: Phase 2
Study type: Interventional

The 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.
