NCT ID: NCT02939352 Completed - Alcoholism Clinical Trials

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

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.

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 Not yet recruiting - Clinical trials for Cocaine-Related Disorders

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

Start date: December 2016
Phase: N/A
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.

NCT ID: NCT02892851 Recruiting - Cocaine Addiction Clinical Trials

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

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: NCT02798627 Recruiting - Clinical trials for Cocaine Use Disorder

Trial Of NS2359 For The Treatment of Cocaine Dependence

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

NS2359 attenuates the euphoria associated with cocaine use. In a manner parallel to cocaine, NS2359 blocks the reuptake of dopamine (DA), norepinephrine (NE), and serotonin (5HT) with nanomolar affinities at the 3 transporters. In primates NS2359 significantly attenuated cocaine self-administration. In several phase II clinical trials for major depressive disorder and adult attention deficit disorder, NS2359 did not cause euphoria. NS2359 exhibited no abuse potential in a human laboratory study comparing NS2359 with amphetamine. In a phase I human laboratory interaction study, NS2359 showed no toxicity after 20 or 40 mg of cocaine, but it attenuated the both the rewarding and cardiovascular effects of intravenous cocaine. On the basis of these promising studies, investigators propose a Phase II double-blind clinical trial of NS2359 in cocaine addiction (CA). The proposed trial will involve 100 CA subjects participating in an eight week trial, including a 1-week baseline and 8 weeks of NS2359 or placebo treatment. Four weeks after completing the medication phase, there will be one follow-up visit. Subjects will be randomly assigned to treatment with placebo or 2 mg NS2359 daily, with a possible decrease to 1 mg daily for adverse events. This dose range is selected on the basis of phase I and II evidence of tolerability and NS2359 plasma levels which were associated with blockade of cocaine reward. This project has the potential to identify the first effective pharmacotherapy for CA.
