Neurobehavioral Mechanisms of Choice in Opioid Use Disorder
Opioid Use DisorderThe objective of this protocol is to use probabilistic reinforcement learning choice tasks and magnetic resonance neuroimaging to demonstrate the impact of problematic opioid use and opioid withdrawal on dynamic decision-making and reveal the neurobehavioral and neurobiological processes underlying abnormal task performance. A second objective is to identify an appropriate dose of intravenous remifentanil for subsequent studies in physically dependent individuals with opioid use disorder.
Efficacy and Safety of Sustained-release Dexamphetamine in Patients With Moderate to Severe Cocaine...
Cocaine Use DisorderIn The Netherlands, each year, about 15 thousand people come into treatment because of problems with cocaine use. There is no approved medication for treatment of cocaine addiction and the psychosocial treatment patients receive is not successful for everyone; many return to treatment several times. There is evidence that agonist ("replacement") medications are effective in treating addiction: methadone for heroin addiction; nicotine replacement for smokers. Dexamphetamine is a stimulant medication registered for treatment of ADHD. It may also be effective as agonist treatment for people with cocaine addiction. It will be investigated whether sustained-release dexamphetamine in people with cocaine addiction, participating in routine methadone maintenance treatment for their comorbid opioid use disorder, (1) reduces cocaine use and (2) improves their health and quality of life.
Microdose Buprenorphine Initiation for Opioid Use Disorder
Opioid Use DisorderThe purpose of this study is to test whether low-dose buprenorphine initiation for treatment of opioid use disorder is safe and effective.
Together in Recovery With Veterans Through Employment
Veterans With Opioid Use DisorderThe purpose of this study is to help Veterans who have opioid use problems with gaining and maintaining meaningful employment. The investigators also want to know employment helps with other aspects of the Veteran's life including starting and staying on necessary medications, mental health needs, and feeling a part of society.
Evaluation of the O'Neil Long Acting Naltrexone Implant in Opioid Dependent Persons
Opioid Use DisorderThis study will examine the safety and efficacy of the O'Neil Long Acting Naltrexone Implant (OLANI) in persons with opioid dependency who are seeking relapse-prevention treatment. All participants will be treated in an open label manner. No randomization will occur. The OLANI is a long-acting biodegradable form of naltrexone which is implanted in the abdominal region. It is hypothesized that the OLANI will produce blood levels sufficient to block the effects of opioids for an extended period allowing patients to engage in psychosocial treatment and recovery over the long term. After the initial set of implants, participants will be offered a second set of implants after 13-24 weeks.
Women's Opioid Treatment Follow-up Study
Opioid Use DisorderThe goal of this study is to examine the feasibility of a gender-specific digital intervention for women with opioid use disorder. In this study, women with opioid use disorder will be randomized to receive treatment-as-usual plus a gender-specific digital intervention or treatment-as-usual only. Feasibility, satisfaction, and engagement with the intervention are the primary outcomes and will be measured post-intervention and at two-week, 6-week, and 12-week follow-up visits.
Neuromodulation and Cognitive Training in Opioid Use Disorder
Opioid-use DisorderOpioid Dependence1 moreThe relapsing nature of opioid use disorder is a major obstacle to successful treatment. About 90% of those entering treatment will relapse within one year. To improve treatment outcome, new interventions targeting the underlying brain biomarkers of relapse vulnerability hold significant promise in reducing this critical public health problem. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that can modulate brain connectivity.
Repeated-dose Behavioral Intervention to Reduce Opioid Overdose
Opioid-Related DisordersDrug OverdoseREBOOT is a randomized trial of a repeated-dose brief intervention to reduce overdose and risk behaviors among naloxone recipients with opioid use disorder. It includes an established overdose education curriculum within an Informational-Motivation-Behavior (IMB) model. This study will test the efficacy of REBOOT vs attention-control.
Opioid Use Disorder in Pregnancy in Long-Term Maternal/Infant Outcomes
Opioid-use DisorderOpioid Use2 moreThe objective of this study is to better understand the comprehensive integration of both clinical and genetic factors that will help to identify mothers who could be at an increased risk of poor response to opioid substitution and infants at risk of significant neonatal abstinence syndrome (NAS).
Accelerated Intermittent Theta-Burst Stimulation for Opiate Use Disorder
Opiate DependenceSuicidal Ideation5 moreThis study aims to examine whether multiple spaced sessions of intermittent theta-burst transcranial magnetic stimulation (iTBS) induce anti-depressant responses and reduce opiate cravings in adults with opiate use disorder (OUD). Additionally, we hope to identify whether the effectiveness of iTBS is related to changes in functional connectivity between particular brain areas.
