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: NCT03007394 Recruiting - Clinical trials for Cocaine-Related Disorders

Lorcaserin in the Treatment of Cocaine Use Disorder

Start date: June 19, 2017
Phase: Phase 2
Study type: Interventional

The objective of this study is to evaluate the efficacy and safety of lorcaserin in the treatment of cocaine use disorder.

NCT ID: NCT02994875 Recruiting - Cocaine Dependence Clinical Trials

Functional Magnetic Resonance Imaging of N-acetylcysteine in Cocaine Dependence

Start date: May 2016
Phase: Early Phase 1
Study type: Interventional

The objective of this research is to identify the functional neural mechanisms (as assessed using fMRI) of short-term N-acetylcysteine (NAC) administration among methadone-maintained individuals with cocaine dependence.

NCT ID: NCT02986438 Recruiting - Clinical trials for Cocaine-Related Disorders

Treatment With Transcranial Magnetic Stimulation for Cocaine Addiction: Clinical Response and Functional Connectivity.

TMS_COC_CONN
Start date: May 1, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate the short and long term clinical and cognitive effects of repetitive Transcranial Magnetic Stimulation (rTMS) at 5 Hz and/or 10 Hz frequencies on the left dorsolateral prefrontal cortex in cocaine dependent patients and to examine possible changes in brain structure and functional connectivity associated with this intervention.

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: NCT02935101 Terminated - Cocaine Dependence Clinical Trials

Effects of Glucocorticoids on Craving During Detoxification Treatment of Heroin and/or Stimulants

Goliath
Start date: October 2016
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate whether prednisolone lowers intensity and frequency of craving in heroin-addicted subjects undertaking a detoxification of cocaine and/or heroin.

NCT ID: NCT02927236 Recruiting - Cocaine Dependence Clinical Trials

Theta-Burst Stimulation as a Treatment for Reducing Cocaine Use

Start date: October 6, 2016
Phase: Phase 1/Phase 2
Study type: Interventional

Background: More effective treatments for people with cocaine use disorder are needed. Researchers want to understand the parts of the brain involved in the disorder. Transcranial magnetic stimulation (TMS) stimulates parts of the brain. A form of TMS called intermittent theta-burst stimulation (iTBS) may help reduce cocaine use. Researchers want to learn how the brain might change with treatment. Objectives: To test if iTBS can reduce cocaine use. Also, to learn how cocaine changes the heart and the brain. Eligibility: Healthy, right-handed adults ages 18-60 who do or do not have cocaine use disorder. Design: Participants will be screened with: - Questionnaires - Medical history - Physical exam - Blood and urine tests - Alcohol breath tests In the pilot study, 10 participants with cocaine use disorder will have 10 treatment days over 2 weeks. Half will be inpatient and half will be outpatient. They will have 2 follow-up visits. Treatment includes: - iTBS: A coil is placed on the head. A brief electrical current passes through the coil. They view cocaine-related images during each session. Sessions are videotaped. - Repeat of screening tests - In the main study, participants will be randomly assigned to have either real or fake iTBS. - Participants with cocaine use disorder will join an incentive program to quit. - Participants will have 39 visits over 6 months. These include: - Repeat of screening tests - MRIs at 5 visits: Participants lie on a table that slides into a cylinder that takes pictures of the brain. They respond to images while in the scanner. - iTBS at 10 visits (5 days a week for 2 weeks) Participants will be contacted throughout the study to discuss iTBS treatment and drug use.

NCT ID: NCT02915341 Enrolling by invitation - Clinical trials for Cocaine-Related Disorders

Towards Detecting Cocaine Use Using Smartwatches in the NIDA Clinical Trials Network

AutoSense
Start date: May 1, 2016
Phase:
Study type: Observational

The overall objective of this study is to extend previous work in the development of methods to automatically detect the timing of cocaine use from cardiac interbeat interval and physical activity data derived from wearable, unobtrusive mobile sensor technologies. The specific objectives of this protocol are to characterize under which conditions high quality continuous interbeat interval data and physical activity data can be obtained from a specially developed smartwatch device in the natural field setting among a population of cocaine users. In addition to identifying common failure scenarios and understanding wearability/usage patterns when collecting interbeat interval from smartwatches, this study will extend previous work in the detection of cocaine use via interbeat interval and physical activity data that were previously obtained from wearable chestband sensors. Information from this study will contribute toward the adaptation of the investigators' existing computational model for detecting cocaine use via the chest sensors, so it can be applied to the interbeat and physical activity data obtained from less obtrusive smartwatches.

NCT ID: NCT02896712 Recruiting - Clinical trials for Cocaine-Related Disorders

Developing Adaptive Interventions for Cocaine Cessation and Relapse Prevention

Start date: January 2016
Phase: Phase 2
Study type: Interventional

First, the investigators will determine whether Acceptance and Commitment Therapy in combination with Contingency Management increases initial treatment response rates. Second, for patients who do not respond to initial treatment, the investigators will examine whether dopamine-targeted pharmacotherapy is an effective augmentation strategy. Third, for patients who respond to initial treatment, the investigators will assess the relative benefit of continued treatment with Acceptance and Commitment Therapy in combination with Contingency Management, as compared to Drug Counseling in combination with Contingency Management, to prevent relapse.
