Social Functioning in Opioid Use Disorder

Problems with social functioning are core to opioid use disorder (OUD), though specific, modifiable social functioning targets and how they relate to OUD treatment outcomes are poorly understood. This study will utilize both data from both patients with OUD and their concerned significant other (CSO) to examine associations between specific social functioning metrics and OUD treatment outcomes. Findings from this study will inform future precision-medicine approaches for people with OUD, a population in significant need of enhanced treatment approaches to combat opioid morbidity and mortality.

Contingency Management to Improve Medication for Opioid Use Disorder Continuation After the Emergency Department

Project Summary The goal of this pilot clinical trial is to assess contingency management (CM) for increasing attendance at outpatient clinics after Medication for Opioid Use Disorder (MOUD) prescription and clinic referral occurred in the hospital Emergency Department (ED). * The researchers will compare usual care (UC)+CM to UC alone to see if 1) CM works to promote MOUD clinic attendance after discharge from the ED and 2) demonstrate feasibility of providing CM in the ED and outpatient MOUD clinic settings. * Researchers will randomize 30 adults who started MOUD in the ED into two conditions. These conditions consist of (A) UC alone: A referral to an outpatient buprenorphine or methadone provider with reminders from STAR program staff or (B) UC+CM: UC plus financial incentives dependent on MOUD clinic attendance to receive an MOUD prescription. The primary outcome of interest is the number of participants who receive their first MOUD prescription from the outpatient clinic after discharge from the ED in UC+CM compared to the UC-only condition. A secondary outcome will be the proportion of participants who kept attending outpatient MOUD treatment by the end of the 30-day study period between UC+CM and UC conditions. An exploratory outcome will be biochemically-verified illicit opioid abstinence measured at day 30.

Measuring the Effects of Neurostimulation on Risky and Ambiguous Decision-Making Capacity in People With and Without Substance Use Disorder

Background: The purpose of this study is to understand how a type of brain stimulation, transcranial magnetic stimulation (TMS), may help those who use opioids such as heroin or methadone. TMS uses brief magnetic pulses to affect brain activity, and is approved by the FDA to treat some mental health problems and substance use. We will evaluate how TMS may help make it easier to make certain kinds of decisions that could help one manage their opioid use. Our findings may provide support for the use of brain stimulation as a treatment to reduce opioid use. Objective: To understand how TMS affects brain activity associated with decision making in people who do and do not use opioids. Eligibility: People aged 18 to 60 years with an OUD. Healthy volunteers are also needed. Design: Participants will have up to 3 clinic visits over 1 to 3 months. All participants will be screened to check if they are eligible to take part in this study. This study is completed in two parts. All eligible participants will complete the first part of the study. In the first part, you will receive one baseline magnetic resonance imaging (MRI) scan so we can take pictures of your brain while you complete computer tasks in the scanner. In these tasks, you will be asked to identify colors of words, view different images and play a game in which you can win money. If you can safely receive TMS, you will be invited to complete the second part of the study. In this part of the study, you will receive TMS and MRI over 2 sessions. For TMS, a coil will be placed on your head and a short electrical current will pass through the coil to create a magnetic pulse that stimulates your brain. You will also repeat the MRI scan and computer tasks. During one of the TMS visits you will receive active or real TMS. In the other, you will receive sham or placebo TMS, which feels like real TMS but does not affect the brain. You will receive both types of TMS. In all sessions, your urine and breath will be tested for drugs and alcohol, and you will complete questionnaires about mood and health....

Behavioral Optimization for Overcoming Suboptimal Treatment Retention (BUP-BOOSTeR)

Buprenorphine, a medication for opioid use disorder (MOUD), is associated with decreased opioid overdose and all-cause mortality. Treatment outcomes improve if patients remain on MOUD for at least six months, a period recommended by expert guidelines, although most studies report retention on MOUD of 50-65% at 3-6 months. Psychosocial interventions have the potential to improve MOUD treatment retention particularly when applied in combination in efficient delivery systems. The objective of this study is to develop an effective and efficient multicomponent intervention to increase buprenorphine retention at 6 months through an optimization trial.

Impact of Federal and State Medications for Opioid Use Disorder (MOUD) Policy Changes During the Pandemic

"Gold-standard" medications for opioid use disorder (MOUD) treatment combines FDA-approved medications, primarily methadone and buprenorphine, with behavioral therapies to provide "whole-patient" treatment. Prior to the pandemic, methadone and buprenorphine were subject to greater federal regulations than medications for other substance use disorders, including medication for alcohol use disorder (MAUD), which created barriers to MOUD initiation and retention. These barriers were exacerbated by physical distancing and diminished clinic capacities during the COVID-19 pandemic. To prevent healthcare disruption and expand access to MOUD treatment during the public health emergency, federal and state authorities implemented several MOUD policy changes during the pandemic to reduce barriers to MOUD initiation and retention, which subsequently became permanent. This study is an evaluation of the impacts of these policies on treatment use, retention, and patient outcomes pre- and post-MOUD policy implementation.

Longitudinal Neural Fingerprinting of Opioid-use Trajectories

This project aims to collect a densely sampled neuroimaging dataset among individuals receiving medications for opioid use disorder (MOUD). MOUD is multiphasic, comprised of medication induction, stabilization, ongoing treatment, and eventual dis-continuation phases. However, with a few small exceptions, existing neuroimaging efforts are almost exclusively single time-point assessments which, by definition, fail to capture these clinically relevant transitions and thus also do not capture individual risk and resilience trajectories. The investigators innovation, the characterization of neurocomputational trajectories during clinically relevant phases of MOUD treatment, will provide unprecedented mechanistic insight into the neurobiological basis of recovery. Once characterized, such trajectories may be used in the identification of specific therapeutic windows for additional intervention (e.g., times of increased neural plasticity) and in the design of novel tailored interventions based on known brain mechanisms (e.g., behavioral therapy, neurostimulation, neurofeedback).

MHealth Incentivized Adherence Plus Patient Navigation

Polysubstance use involving opioids and methamphetamine is emerging as a new public health crisis. Patients with opioids and methamphetamine use often experience serious medical complications requiring hospitalization, which provides an opportunity to offer addiction treatment. Yet linkage to outpatient treatment post-discharge is suboptimal and methamphetamine exacerbates outcomes. The investigators propose to pilot test "MHealth Incentivized Adherence Plus Patient Navigation" (MIAPP) to promote treatment linkage and retention for patients with opioid use disorder (OUD) and methamphetamine use who initiate buprenorphine in the hospital. The investigators Aim is to perform a two-arm, pilot randomized clinical trial (n=40) comparing MIAPP + treatment-as-usual (TAU) versus TAU alone on outpatient medication for opioid use disorder (MOUD) linkage within 30 days (primary) and 90-day retention on medications (secondary) among hospitalized patients with OUD and methamphetamine use.

A Study to Test Whether BI 1356225 Improves Impulsive Behavior in People With Opioid Use Disorder Who Are Taking Buprenorphine

This study is open to people between 18 and 65 years of age with opioid use disorder. Opioid use disorder is also called opioid addiction or opioid dependence. People can join the study if they currently take a medicine called buprenorphine. People with opioid dependence can act on impulse, which can lead to risky behaviours. The purpose of this study is to find out whether a medicine called BI 1356225 improves impulse control in people with opioid dependence. Participants are put into 2 groups by chance. One group takes BI 1356225 tablets and the other group takes placebo tablets. Placebo tablets look like BI 1356225 tablets but do not contain any medicine. Participants take a tablet once a day for 8 days. All participants also continue taking buprenorphine. Participants are in the study for up to 6 weeks. During this time, they visit the study site 3 times. At visit 2, participants stay at the study site for 9 nights. Doctors test participants' impulsivity using tasks or games on a computer and questionnaires. The results are compared between the 2 groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.
