Changes in the communication of glutamate from one brain structure to another are important in the development of therapy for cocaine use disorders. Our preliminary investigations suggest that drugs that affect glutamate exchange may be effective at promoting and maintaining individuals' abstinence from cocaine. The purpose of this randomized, double-blind, controlled trial is to test various glutamate modulators in conjunction with motivational enhancement therapy (MET) and mindfulness based relapse prevention (MBRP) for cocaine use disorders.
Reduced drug use is a clinically meaningful target for treatment development, but few studies have evaluated the positive impacts produced by this behavioral change, preventing adoption of this endpoint in clinical trials. The proposed research will fill that critical knowledge gap by demonstrating the biopsychosocial benefits of reduced cocaine use. These data will be used to change current accepted cocaine treatment endpoints and accelerate identification of therapies for cocaine use disorder.
This project is a placebo-controlled, double-blind randomized trial evaluating the feasibility, tolerability, acceptability and adherence for lorcaserin among actively using, men who have sex with men (MSM) with cocaine use disorders.The study will enroll 45 individuals who will randomly be assigned to either the treatment (lorcaserin) arm or the placebo arm, to be taken twice a day for 12 weeks.
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.
EMB-001 is a combination of 2 drugs: the cortisol synthesis inhibitor, metyrapone (Metopirone®), and the benzodiazepine receptor agonist, oxazepam (original trade name Serax®; now marketed as oxazepam (generic) only). This Phase 1b cocaine interaction study is being conducted in order to assess the safety and PK of EMB-001 and cocaine in combination.
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.
The purpose of this study is to determine the effectiveness of a medication called suvorexant in reducing anxiety, improving sleep, and reducing cocaine cravings or cocaine use.
The purpose of this research study is to determine whether a medication called pioglitazone (trade name Actos) can reduce behavioral problems associated with cocaine use, improve brain structural changes associated with cocaine use and reduce cocaine craving and drug use in cocaine dependent patients.
This study will determine the influence of methylphenidate (e.g., Ritalin®) and duloxetine (Cymbalta®), alone and in combination, on the cocaine use as measured by self-report and urine drug screens.
