This is a Phase 2 single-blind, randomized, multicenter study to compare the efficacy and safety of a single dose of TNX-1300 to placebo with usual care in patients with acute cocaine intoxication within the emergency department setting.
The goal of this clinical trial is to compare the effects of active repetitive transcranial magnetic stimulation (rTMS) to sham (placebo) rTMS prior to cognitive-behavioral therapy (CBT) as a treatment for adults with cocaine use disorder. The main questions it aims to answer are: - Is rTMS safe and feasible as an augmentation for CBT for the treatment of cocaine use disorder? - What is the brain mechanism of rTMS? - Will active rTMS (compared to sham rTMS) followed by CBT help adults with cocaine use disorder achieve abstinence from cocaine? Participants will: - Have two brain MRI scans; - Undergo 3 weeks of daily rTMS (or sham) treatments (15 sessions), and; - Have 12 weeks of once-weekly cognitive-behavioral therapy for the treatment of cocaine use disorder. Researchers will compare active (real) rTMS to sham (placebo) rTMS. All participants will receive cognitive-behavioral therapy.
This study aims to understand the role of Low-Intensity Focused Ultrasound on craving levels for cocaine as evidenced by diagnostic imaging of the dorsal anterior insula (dAI) and subjective ratings. Data analysis will serve to show if 1) LIFU is safe and effective and to 2) examine the effects of LIFU on dAI BOLD activity and craving in response to cocaine cue-exposure. The study will screen 60 individuals with Cocaine Use Disorder (CUD) to arrive at 30 enrolled subjects, based on a 2:1 screen/randomization ratio.
Brief Summary: Background: Cocaine use disorders (CUD) is a multifactoral disease, involving several brain areas. One of the most investigated is the Dorsolateral Prefrontal Cortex (DLPFC) involved in impulsiveness control. Effective treatments for CUD are still needed and repetitive Transcranial Magnetic Stimulation (rTMS) is widely studied for its potential in reducing cocaine craving and consumption. Objectives: The main outcome is to test if rTMS can be related to neuroplasticity and neurotrophism through changes in Brain-Derived Neurotrophic Factor (BDNF) and its precursor (pro-BDNF) levels. Eligibility: Healthy, right-handed adults ages 18-65 who do have cocaine use disorder (moderate to severe). Design: This is a randomized, sham-controlled study. The study includes a rTMS continued treatment phase compared to healthy control (HC) evaluation. Prior to participating, participants will be screened with: - Medical history - Anamnestic sheet - Physical exam - Urine tests After being enrolled, participants and HC will undergo venous blood sample (BDNF and proBDNF levels). During the continued rTMS phase, participants with cocaine use disorder will be randomized to receive real or sham rTMS; a former arm is also provided and is made up of HC. RTMS will be delivered in 10 days, over 2 weeks (5 days/week). After the last rTMS session a blood sample for neurotrophines levels will be collected. Treatment includes: - rTMS: A coil is placed on the head. At each session, participants will receive two rTMS sessions, with a 50 mins interval. At the beginning of each rTMS session, they view cocaine-related images for few minutes (cue-induced stimuli). - BDNF/proBDNF levels: A venous blood sample will be collected before the first stimulation and after the last stimulation of the intensive-stimulation period (first two weeks), this sample will be also collected from HC. The blood sample will be centrifuged within 20 minutes of sampling at 1000 × g for 15 minutes. Then, the serum will be aliquoted and stored at -80 ° C until analysis. - Urine toxicological screen
A dose escalation study to assess the efficacy and safety of Clavulanic Acid (CLAV) vs. placebo (PBO) for the treatment of cocaine use disorder (CUD)
Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation in which low level electrical currents are applied to the scalp in order to alter brain function. In a prior Phase-I study, the research team demonstrated feasibility of self-administration of a home-tDCS prototype in 14 patients that applied 15 sessions for each patient at an outpatient center.
The purpose of the study is to determine feasibility of repetitive transcranial magnetic stimulation (rTMS) for individuals with moderate to severe cocaine or methamphetamine use disorder (CUD/MUD). Potential participants will be age 18-65, and interested in cutting down or stopping use. Participants will be randomized to one of two groups; groups will receive rTMS or sham rTMS (placebo) over the course of an 8-week treatment period, and complete follow-up assessments at the end of treatment, 12, and 16 weeks post-randomization.
The purpose of this study is to test the safety of a novel gene viral vector treatment for adults with cocaine use disorder-sustained remission. This gene regulates an enzyme (cocaine hydrolase) that breaks down cocaine into inactive substances, thereby decreasing the pleasurable feeling this drug usually provides.
A dose-escalation study to determine the optimum dose of Clavulanic Acid (CLAV) for effects on craving and efficacy.
The purpose of this study is to determine if synchronized transcranial magnetic stimulation is safe and tolerable in individuals with cocaine, opioid, or alcohol use disorders.
