Active clinical trials for "Opioid-Related Disorders"

This study will disseminate five surveys collecting individual's attitudes and experiences during buprenorphine treatment for Opioid Use Disorder during the COVID-19 pandemic.

The overarching goal of this project is to have a consolidated consent and evaluation procedure that will lead potential subjects to the most appropriate clinical trial or human laboratory study (and its consent process) for their presenting concerns or interests. A second purpose is to have a consolidated intake data base on which secondary analyses can be conducted.

The purpose of this study is to observe and assess the successful taper and opioid withdrawal experience after participants stop receiving SUBLOCADE because their healthcare provider determines their disease symptoms have been controlled for at least 9 months and they, together with their healthcare provider, plan to discontinue MOUD.

There are more than 2.1 million people in the United States with opioid use disorder, and according to preliminary data from the US Centers for Disease Control and Prevention opioid overdose deaths rose 36% to more than 69,000 deaths in 2020. Treatment with buprenorphine or methadone reduces overdose deaths in patients with opioid use disorder. However, most patients with opioid use disorder do not receive treatment. In addition to the rising rates of morbidity and mortality, the healthcare, social, and societal costs of the opioid epidemic are roughly one trillion dollars annually. Rapidly scalable strategies are needed to increase access to treatment and improve treatment retention. The investigators propose a novel buprenorphine micro-dosing study to evaluate the pharmacokinetics, treatment retention, and qualitative outcomes in participants transitioning from methadone maintenance therapy to buprenorphine using a micro-dosing initiation in the outpatient setting. The proposed study will report participant pharmacokinetics, treatment retention, Clinical Opiate Withdrawal Scale (COWS) score, Treatment Satisfaction Questionnaire for Medication (TSQM) score, and other qualitative outcomes.

This outpatient study is designed to examine the potential relationship between non-fatal opioid overdose and cognitive functioning. This study will also examine the impact of computerized working memory training on relevant outcomes (cognition, psychosocial functioning, quality of life, drug use). The training component of the study lasts 1 month, with follow up visits and 1-month and 3-months post training.

The aim of this study is to describe outcome of people with opioid use disorder over the long-term by collecting monthly and yearly data on their recovery. Adults with opioid use disorder who participate will complete surveys monthly online and once per year by phone about their substance use, mental health, treatment involvement and functioning. The goal of this study is to better understand how people with opioid use disorder recover over time to improve intervention for this group.

This is a human laboratory-based, randomized, cross-over study in which buprenorphine will be administered to healthy volunteers (n=22) in 3 separate inpatient 2-night visits, at least 1 week apart. At each visit, the participant will receive a single dose buprenorphine, either 0.15mg IV, 8mg PO, or 16mg PO. The order for the first dose administered will be fixed to the IV dose, and the subsequent doses will be randomized and counterbalanced to 8mg or 16mg PO. Participants will be given naltrexone to produce opioid blockade to eliminate the risk for opioid dependence in individuals without OUD. Timed blood samples will be collected up to 24 hours.

There is growing recognition of the need for approaches to initiate treatment wherever patients touch the health care system, including the Emergency Department (ED). Most research has focused on initiation of medications for opioid use disorder (MOUDs) in the ED rather than ensuring continued treatment post-discharge. The investigators propose to adapt evidence-based interventions to support patients' complex needs and facilitate continued treatment, rather than discharging them and having them navigate outpatient treatment systems with limited support. The research team will randomize participants into 1 of 4 arms to receive varying degrees of augmented usual care, including daily check-ins and contingency management. The investigators plan to examine the effects of check-ins and contingency management on engagement with addiction treatment and equity of treatment effects among racial and ethnic subgroups and assess important moderators of treatment effects.

Background Back pain is among the most common cause for sick leave in the working population and is the main cause of years lived with disability globally. In Norway, about 30% report to live with chronic pain and women are affected more than men. Pharmacological strategies for pain management e.g., opioid medications, is a common treatment method. This is despite clinical guidelines suggesting limiting pharmacological treatment in management of chronic back pain. Long-term use of opioids is linked to opioid-induced hyperalgesia, paradoxically. However, it is suggested that RNA sequencing (seq.) profiling may identify individuals that are at risk of opioid-induced hyperalgesia. To help reduce medication intake brief intervention (BI), a method for discontinuing long-term medication use, has shown to be successful. In this pilot RCT the investigators aim to investigate the feasibility of a full scale RCT and observational study using BI on opioid-using patients with back pain and concurrently study if the response can be predicted by RNA seq. Method Ten outpatients aged 18-67 years with back pain will be recruited from the orthopaedic department at Akershus University Hospital. Inclusion criteria includes daily use of opioids for more than two weeks consecutively, and sufficient language (Norwegian) skills. Exclusion criteria includes severe medical or surgical condition such as cauda equina syndrome, rheumatic disease, psychiatric disease, or recent surgery. The patients will be randomised into two groups (5+5) where one group receives the BI and the other gets treatment as usual. Data collection will be conducted at three-time points; baseline, four weeks follow-up and three months follow-up (end of trial). The primary outcome for this pilot RCT is to test feasibility and estimate effect size for a later full-scale study. Secondary outcomes include subjective and objective findings from the data collection. Results Primary results concerning feasibility are mainly qualitative and will be presented as such. Secondary results including demographic information as well as tentative effect size, patient reported outcomes such as pain intensity, anxiety, depression, quality of life, psychosocial stressors in the workplace and the RNA seq will be presented descriptively. Conclusion The results from this pilot study will assist in constructing the optimal design for a full-scale RCT.

This study will investigate the mechanisms of cognitive-behavioral response to medications used for relapse prevention in opioid use disorder (opioid addiction, OUD), through investigation of the neural circuits underlying key cognition functions. The study will use previously validated cognitive probes, functional Magnetic Resonance Imaging (fMRI), and novel extended-release injectable preparations of opioid partial agonist buprenorphine and antagonist naltrexone, in OUD patients to explain the individual heterogeneity of OUD treatment response.
