Medications for Opioid Use Disorder Photosensitive Retinal Ganglion Cell Function, Sleep, and Circadian Rhythms: Implications for Treatment

Opioid use disorder (OUD) is a treatable medical illness with three medications FDA approved for treatment. However, persons with OUD report significant sleep disturbance, even when treated with medications for opioid use disorder, leading to high rates of relapse. In this project, we will investigate a special set of photosensitive neurons in the retina as an underlying mechanism for circadian rhythm and sleep disturbance from opioid use and medications for OUD that could lead to novel intervention and improve treatment outcomes.

Technology-Enhanced Therapy vs. Medication Monitoring for Buprenorphine Retention in Pregnant Persons

This study involves testing how useful a technology-enhanced therapy is for pregnant people prescribed buprenorphine for the treatment of opioid use disorder, compared to medication monitoring. Participants are randomized to one of the conditions. If participants are randomized to receive the therapy, participants will attend four 60-minute therapy appointments during pregnancy with an additional 30-minute therapy session towards the end of pregnancy, and 6 additional monthly postpartum (after childbirth) sessions (0-6 months postpartum). As part of the therapy program, participants will receive access to a mobile application, which will be accessible for the duration of the study. If participants are randomized to medication monitoring, participants will be asked to log each time participants take their medication for two months. All participants will also be asked to complete questionnaires at enrollment and again at 3-month postpartum and 6-months postpartum, and will be contacted randomly throughout the study to perform a medication count. The total duration of the study is between 8-12 months depending on when participants enroll (early second trimester-mid third trimester).

Project STRONGER: Stepped Care for Opioid Use Disorder Treatment Engagement and Recovery

Using a hybrid type 1 effectiveness-implementation approach, this study aims to evaluate the impact of a novel stepped care model ("PCT+2HOPE") versus treatment as usual (TAU) on increasing retention in community-based medication for opioid use disorder (MOUD) treatment among women who have experienced intimate partner violence (W-IPV). PCT+2HOPE includes Present-Centered Therapy (PCT+) with stepped care as indicated by moderate, severe, or extreme PTSD-related impairment in psychosocial functioning to Helping to Overcome PTSD through Empowerment (HOPE), two evidence-based behavioral interventions adapted for women with opioid use disorder (OUD). We will examine the effectiveness of PCT+2HOPE vs. TAU on the primary outcome (i.e., retention in MOUD treatment) and secondary outcomes related to trauma (i.e., PTSD-related impairment in psychosocial functioning and depression), substance use (i.e. OUD symptom severity, extra-medical opioid use \[i.e., use of prescription opioids without a doctor's prescription; in greater amounts, more often, longer than prescribed, or for a reason other than a doctor said they should be used\], and recovery), and empowerment. We will explore the extent to which the effectiveness of PCT+2HOPE vs. treatment as usual differs based on access to basic needs. We will also conduct an implementation-focused process evaluation.

Buprenorphine as a Post-operative Analgesic in Opioid-Naive Patients After Ankle Fracture Surgery

Addictive full-agonist opioids, like oxycodone and hydrocodone, are often used to treat pain after surgery. However, these full-agonist opioids can be very addictive. After ankle fracture surgery, about 1 in 5 patients that did not take opioids before surgery become addicted to opioids after surgery. Buprenorphine is an opioid with unique properties that may offer a way to reduce the number of patients that become addicted to opioids after surgery. Buprenorphine has good analgesic (painkilling) effects. It is also thought to be less addictive and cause less of a high than full-agonist opioids, like oxycodone and hydrocodone. This project's goal is to determine if transdermal buprenorphine can safely and effectively control pain after ankle fracture surgery. This study will be a pilot study, which sets the stage for future studies that investigate whether buprenorphine can reduce the rate that patients become addicted to opioids after surgery. This study's multidisciplinary team will divide patients into two groups. Participants in one group will be treated with a 7-day transdermal buprenorphine patch (where the buprenorphine is slowly absorbed through the skin over 7 days). Participants in the other group will be treated with a placebo patch. A placebo has no drug in it, it just looks like the buprenorphine patch. Aside from the buprenorphine patch or placebo patch, both groups' pain management plans will be the same as if they were not in the study. Over the first week after surgery, the investigators will measure the amount of full-agonist opioids (for example, oxycodone or hydrocodone) that participants consume, participants' pain scores, the frequency of side effects related to opioids, and the number of calls and patient portal messages to the clinic for uncontrolled pain. The investigators will also assess whether participants are continuing to use opioids 3 months after surgery for pain related to their ankle fracture.

PrEP and MOUD Rapid Access for Persons Who Inject Drugs: The CHORUS+ Study

The US opioid overdose epidemic has been accompanied by an increase in human immunodeficiency (HIV) among persons who inject drugs. HIV pre-exposure prophylaxis (PrEP) is an FDA approved medication taken daily orally by individuals who are HIV negative, but who are at increased risk for HIV. In order to obtain PrEP, a prescription is needed. Before being prescribed HIV PrEP, it is recommended by the Centers for Disease Control and Prevention (CDC) to obtain an HIV test first. Although home HIV self-test kits are recommended by the CDC and are locally available, uptake remains low. CHORUS+ (Comprehensive HIV, Hepatitis C, and Opioid Use Disorder Response to the Unaddressed Syndemic +) is a theory-based, peer-delivered, mobile phone-supported intervention focused on enhancing uptake and adherence to HIV PrEP (primary outcome), and continuation of MOUD (secondary outcome) among persons who inject opioids. At recruitment, the intervention will include HIV self-testing, rapid initiation of PrEP and MOUD, and 6-month peer recovery coaching (PRC) to support adherence to these medications. This research study seeks to determine the efficacy of a novel intervention to increase the uptake of evidence-based measures to prevent HIV and treat opioid use disorder. The efficacy of this multi-site, two-arm randomized control trial of CHORUS+ and usual care \[passive referral\]. This study is not testing the efficacy of PrEP or HIV home testing which is already known. In addition the investigators will determine the influence of HIV self-testing on PrEP uptake and adherence. In the CHORUS+/ intervention arm, there will be a baseline in-person session with the participant to encourage uptake of PrEP and MOUD using motivational interviewing (MI).

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.

tAN for PTSD and OUD in Buprenorphine Therapy

The goal of this research study supported by the HEAL Initiative (https://heal.nih.gov) is to investigate the effects transcutaneous auricular neurostimulation (tAN), as delivered through the Sparrow Ascent device, on helping people with co-occurring posttraumatic stress disorder (PTSD) and opioid use disorder (OUD) start and continue buprenorphine treatment. The main questions it aims to answer are: * Does the tAN help participants with OUD and PTSD remain in buprenorphine therapy for three months after starting use of the device (i.e., randomization to treatment condition)? * Do participants find the Sparrow Ascent device to be acceptable and use it? * Do participants find the Sparrow Ascent device to be tolerable and comfortable to use? * Do participants find the Sparrow Ascent device to be easy to use with their buprenorphine therapy? * Do participants follow the minimum recommended dose schedule for the Sparrow Ascent device most of the time? Participants will complete a baseline assessment to make sure that they are eligible to participate in the study. The assessment captures information about demographics, substance use and treatment history, opioid withdrawal symptoms and craving, difficult life experiences and PTSD symptoms, mental health and treatment history, quality of life, and recovery resources. After the assessment is complete and the participant has been inducted on buprenorphine as part of standard care, they are randomized to one of two treatment conditions: active tAN and placebo. Participants are trained on how to use the device and return for 12 weekly research visits to check on recent substance use and craving, PTSD symptoms, and their experience using the device. After 12 weeks of using the device, participants will complete a post-active treatment assessment that is nearly identical to the baseline assessment to see if there have been changes in these areas. Researchers will access the medical record to determine whether there is a current prescription for buprenorphine at three months and six months after randomization.

Multi-System Analysis of Opioid Receptor Binding

This study will enroll up to 60 adults (including 30 females and 30 males) in three cohorts of up to 20 subjects each. In all three groups, \[11C\]carfentanil whole-body PET imaging will be used to examine the central nervous system (CNS) and broader systemic opioid binding in an initial scan session. In the two groups not receiving standard of care medication assisted treatment (MAT) for opioid use disorder (OUD) the effects on \[11C\]carfentanil binding potential of the blockade of opioid binding by the non-selective opioid antagonist naloxone administered parenterally in a second scan session will also be examined. If two scans are completed they can be done on the same day or on different days.

Remotely Observed Methadone Evaluation II

Methadone is an effective treatment for severe opioid use disorder (OUD), but access is limited due to the requirement of daily observed dosing by most opioid treatment programs (OTPs). Sonara Health designed a HIPAA-compliant web-application called Sonara that features integrated video dosing recording, a tamper-evident seal, and an innovative measurement-based care (MBC) framework called the Opioid Craving Visual Analogue Scale (OC-VAS) to facilitate methadone take-homes while providing evidence of appropriate use and monitoring patient outcomes. Phase II of this SBIR aims to compare Sonara against usual take-homes to assess its impact on retention in care, opioid use, patient outcomes, and costs of care.
