Filter by:The overarching hypotheses of this protocol are that (1) persistent brain glutamate changes induced by chronic opioid use will exacerbate use of cocaine during opioid physical dependence and withdrawal and (2) n-acetylcysteine (NAC) will ameliorate glutamatergic dysregulation, and thus will reduce both opioid and cocaine demand. These hypotheses will be tested with two specific aims. Specific Aim 1. Determine the reinforcing effects of cocaine in individuals with comorbid opioid and cocaine use disorder with physiological dependence on opioids during NAC maintenance. All subjects will be maintained on oral hydromorphone. They will also be randomly assigned to receive placebo or oral NAC (2.4 g/day), stratified by sex. After dose stabilization, experimental sessions will be conducted in which subjects complete hypothetical cocaine purchase tasks during opioid maintenance and opioid withdrawal. The hypotheses are: 1) cocaine purchasing will be greater during opioid withdrawal and 2) NAC maintenance will attenuate cocaine purchasing across opioid maintenance and withdrawal periods. Specific Aim 2. Evaluate glutamate functionality during periods of opioid maintenance and withdrawal in individuals with comorbid opioid and cocaine use disorder and physiological dependence on opioids during NAC maintenance. Subjects will undergo magnetic resonance spectroscopy to evaluate brain glutamate changes as a function of opioid maintenance/withdrawal state and NAC maintenance. The hypotheses are: 1) glutamate levels will be elevated during opioid withdrawal and 2) NAC maintenance will ameliorate elevated glutamate levels.
The proposed project seeks to use public health and clinical data on opioid use disorders (OUD) outcomes for mother and infants, which is the leading cause of death to mothers one year after deliver and can lead to neonatal withdrawal syndrome (NOWS) and other poor outcomes. Insufficient or incomplete data about OUD and lack of integrated programs for OUD treatment during pregnancy can be barriers to providing optimal care to mothers and infants.
The investigators propose to conduct a dose-escalation trial of an FDA-approved antiepileptic drug, lacosamide, added to opioid therapy in patients with chronic abdominal pain from chronic pancreatitis (CP). This pilot trial will test the feasibility of the study design and provide reassurance regarding the tolerability and safety of lacosamide used concomitantly with opioids in this patient population to reduce the condition known clinically as opioid-induced hyperalgesia (OIH).
This project aims to elucidate the brain effects of opioid use disorder (OUD) treatments. The study will investigate the cognitive effects of extended-release preparations of a partial opioid agonist and an antagonist. To this end, the study will use up to three monthly injections of buprenorphine (XRBUP, Brixadi®) and naltrexone (XRNTX, Vivitrol®). Domain-specific brain activity will be induced by cognitive tasks and recorded with Magnetic Resonance Imaging. Participants will be imaged at baseline and in the interval between the 1st and 2nd injection and followed for up to three months.
This is a prospective, observational, longitudinal study to assess clinical outcomes in the 12-months following participants' exit from protocol SBM-OWP-03, Delivering Transcutaneous Auricular Neurostimulation to Improve Relapse Prevention in Opioid Use Disorder (RESTORE; ClinicalTrials.gov Identifier: NCT05053503). Clinical outcome scores will be collected at study exit from protocol SBM-OWP-03, 1 month, 3 months, 6 months, 9 months, and 12 months after study exit from protocol SBM-OWP-03.
This project, involving two distinct clinical trials, tests whether induction to a higher than currently recommended buprenorphine (BUP) induction dose is safe and can improve the proportion of patients who engage in comprehensive addiction services within 7-day of induction. Trial 1 is a head-to-head comparison of the safety, tolerability and feasibility of high dose BUP induction (32 mg). The study involves two cohorts, (1) a 12mg cohort (standard) to determine baseline data and (2) a 32 mg (high dose) cohort. If the 32mg is intolerable, a 24 mg dose may be evaluated. Trial 2 is a small pilot multicenter randomized, double blinded, clinical trial in 80 participants (randomized 1:1) that will provide preliminary information on efficacy with the primary outcome being engagement in comprehensive addiction treatment 7-days post BUP induction. In collaboration with National Institute on Drug Abuse (NIDA), the research team have determined that there must be a minimum increase in engagement in comprehensive addiction treatment of 15% at 7-days in the high dose induction group to justify a larger future clinical trial.
This randomized, 35-day research study (n=20) explores the effects of a simplified mindfulness intervention in opioid use disorder patients stabilized on buprenorphine maintenance therapy (BMT), aiming to alleviate insomnia, monitor BMT dose, and decrease non-prescribed opioid use. Patients tap along with their breathing at bedtime and practice sleep hygiene; controls do sleep hygiene only. Adherence will be monitored by a smartphone application.
This is a Phase 1, single-centre, randomized, double-blind, placebo-controlled, 2 fixed sequences, multiple dose study in healthy male and/or female recreational opioid users. This study is being primarily conducted to assess the effect on respiratory drive of morphine administered after multiple doses of AZD4041 compared to morphine administered alone in healthy recreational opioid users. The study will include up to 44 participants who will be randomised to either AZD4041 and morphine (28 participants) or placebo and morphine (16 participants). This is to ensure completion of at least 36 subjects (24 AZD4041 + morphine, and 12 Placebo + morphine on Day 15). The total study duration will be up to 54 days (including screening) per participant.
Central Asia (CA) represents the most rapidly growing HIV epidemic region worldwide, concentrated in people who inject drugs (PWID) and their sexual partners, and scaling up opioid agonist therapies (OAT) in this region is the most cost-effective strategy to prevent new HIV infections, and more effective when combined with antiretroviral therapy (ART). The investigators propose to use the Network for the Improvement of Addiction Treatment (NIATx) implementation strategy to scale-up OAT in three diverse Central Asian countries (Kazakhstan, Kyrgyzstan, Tajikistan) and guided by the Exploration-Planning-Implementation-Sustainment (EPIS) framework. Understanding the trajectories of implementation and scale-up in this context may emerge through creating communities of practice, especially when cohesion and competence evolves, and may guide other healthcare delivery challenges in the region (e.g., HIV, TB); as well as build important regional expertise and understanding implementation trajectories should help support OAT program sustainability.
This study is a multisite randomized clinical trial of a treatment designed to reduce pain interference while simultaneously addressing relapse prevention among individuals who have co-occurring chronic pain and Opioid Use Disorder (OUD). This study will recruit approximately 160 individuals who are currently being treated in clinics specializing in the physician management of OUD. To increase generalizability of study findings and increase internal validity of the physician management component of treatment, all participants will be stabilized on buprenorphine for OUD as part of their usual clinical care. Individuals will be randomized to either: (1) enhanced usual care or (2) the integrated ACT + MBRP treatment. The investigators hypothesize that: (1) the combination of ACT + MBRP in buprenorphine-prescribed patients with chronic pain will be more efficacious across primary and secondary outcome measures in comparison to Enhanced Usual Care and (2) examination of treatment mechanism data will indicate treatment-related changes that are consistent with the theoretical models of ACT+MBRP.
