Funded Projects

As the opioid crisis claims more and more lives, there is a need to develop new, safer analgesics. Biased agonists could activate beneficial signaling pathways while avoiding those that cause adverse effects. This project aims to speed the discovery of non-addictive analgesics by providing drug discovery teams with simpler, more robust, more quantitative assays for agonist bias. The goal is to optimize and test new assays for agonist bias at NOP, D3 dopamine, CB1 cannabinoid, and OPRM1 opioid receptors, which couple to both the Gi and ?-arrestin signaling pathway, and create new tools to improve the analysis of structure/activity relationships that can be used in drug discovery and distribute to researchers who are developing new drugs for OUD.

Significant racial, ethnic, socioeconomic, and geographic disparities affect access to opioid use disorder (OUD) treatment and have thus contributed to the opioid overdose crisis. Patient navigator interventions after hospitalization can improve access to treatment, but challenges prevent full adoption of these strategies. These include lack of coordination across institutions, inadequate data sharing, workforce shortages, and lack of awareness, especially in resource-limited communities. This project aims to develop a hospital system-wide patient navigation protocol that can be scaled up to address OUD treatment linkage and continuity after hospitalization.

While effective treatments exist for substance use disorders, adhering to treatment and retaining patients in treatment can be a challenge. The objectives of this project are to facilitate the implementation of loyalty/reward-based programs to increase adherence to medical treatment among patients with substance use disorders through innovative solutions to common challenges. Building on experience developing software to promote patient appointment attendance, the project will build a new tool to test on a sample of 10 providers and 10 patients who are prescribed but not fully adherent to substance use disorder treatment. Patients will receive tailored text messages (in English or Spanish) encouraging adherence, self-report their treatment adherence (which will be verified through smart pill caps and biological testing), earn points for adherence that can be exchanged for rewards customized for them based on a baseline survey, and report their satisfaction with the program and process at the end of the 4-week study. This pilot will assess the feasibility and perceived usefulness of the product in support of eventual larger-scale testing in a clinical trial.

Although there are effective prevention and treatment programs and services to address opioid misuse, opioid use disorder (OUD), and overdose, gaps remain between those needing and those receiving prevention and treatment, in part because of a need to better understand how to make these programs and services most effective at a local level. The National Institutes of Health (NIH) and the Substance Abuse and Mental Health Services Administration (SAMHSA) launched the HEALing Communities Study to generate evidence about how tools for preventing and treating opioid misuse and OUD are most effective at the local level. This multisite implementation research study will test the impact of an integrated set of evidence-based practices across health care, behavioral health, justice, and other community-based settings. The goal of the study is to reduce opioid-related overdose deaths by 40 percent over three years. The University of Kentucky is partnering with academic institutions in three other states to study the impact of these efforts in 67 highly affected communities. The study will also look at the effectiveness of coordinated systems of care designed to increase the number of individuals receiving medication to treat OUD, increase the distribution of naloxone, and reduce high-risk opioid prescribing.

Adolescents and young adults in justice settings (AYAJS) have some of the highest rates of opioid use disorder (OUD), with national rates approaching 20%. Multiple studies have established effectiveness of the Adolescent Community Reinforcement Approach with Assertive Continuing Care (ACRA/ACC) in reducing non-opioid substance use disorder (SUD); however, none have evaluated it as an OUD prevention strategy. SUD is common and costly among AYAJS; thus, ACRA/ACC-based approaches are likely to be effective and cost-beneficial OUD prevention strategies for this group. However, the optimal intensity of an ACRA/ACC-based OUD prevention intervention for AYAJS with and without non-opioid SUD is not known, as these groups are likely to have differing prevention needs. Seattle Children’s Hospital (SCH), University of Washington (UW), and Washington State Juvenile Rehabilitation (WSJR) will collaboratively evaluate ACRA/ACC-based OUD prevention strategies of different intensity levels among SUD and non-SUD youth.

Since 2002, persons with opioid use disorders who desire medication-assisted treatment can be treated with buprenorphine, which has been shown to be efficacious. Buprenorphine treatment can occur in any medical office-based setting, is prescribed by any physician who seeks to become waivered, and is taken by patients at home unsupervised. However, without visual confirmation of medication ingestion, providers remain unsure if patients divert part or all of their buprenorphine medication. This project will develop the technical and logistical workflow needed to implement a video-­based application, miDOT, for office-­based buprenorphine monitoring during the initial months of care, which will allow health care providers to monitor whether patients ingest the drug and adhere to treatment. The project will configure a video-based DOT platform, evaluate its effectiveness in securing medication ingestion and care retention for illicit opiate users, and solidify routes of sustainable commercial viability with commercial partners.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative template of developmental trajectories over the first 10 years of life. All sites in the HBCD-NC will carry out a common research protocol and will assemble and distribute a comprehensive research dataset to the scientific community. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. Most participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first 10 years of life. The Northwestern University study site is in Chicago where rates of prenatal substance use are rising and consistent with the national trend. This site will recruit a diverse urban sample of mother-infant pairs reflecting the population of Chicago.

Opioid dependence is a leading cause of premature illness and death. Previous research suggests that a protein called G-protein coupled receptor (GPR88) controls many addiction-relevant behavioral and physiological actions of opioids. This research study will validate GPR88 as a drug target for opioid use disorder as well as develop novel, brain-penetrant GPR88-binding molecules with properties optimized for treating opioid dependence. This research is an initial step toward the goal of developing GPR88-binding molecules as novel therapeutics to facilitate abstinence in people dependent on opioids.

The first ten years of life are accompanied by rapid changes to the developing brain and cognitive abilities. Complex interacting factors including genetics, early-life exposure to substances, family and social interactions, and home and community environments can affect brain and cognitive development. Three linked projects aim to develop effective research protocols to lay a foundation for a future HEALthy Brain and Cognitive Development (HBCD) birth cohort study. Project 1 will develop protocols for recruitment and retention of a diverse sample of pregnant and postpartum women with oversampling of mothers with prenatal opioid use. Project 2 will identify ethical, legal, and regulatory challenges for investigations in this vulnerable population and define effective solutions to enable recruitment and study of these participants. Project 3 will develop and evaluate protocols for acquiring high-quality, quantitative neuroimaging measures with magnetic resonance imaging and functional near infrared spectroscopy and assess effective strategies for measuring cognitive performance in young children, including those exposed to opioids.

Neonatal Opioid Withdrawal Syndrome (NOWS) affects a growing number of neonates each year due to the ongoing opioid epidemic ravaging the United States. Complex neurobehavioral observation of newborns is the primary modality used. It is subjective and time-consuming by nature, requires significant expertise, and can lead to delays in treatment. The goal of this project is to develop an innovative, low-cost, non-invasive, and easy-to-use brain monitor to objectively assess the severity of withdrawal symptoms in newborns exposed to opioids and provide evidence-based decision support to care providers to improve both short- and long-term developmental outcomes. This device, referred to as NeoGUARD, is based on the continuous, automated, and real-time monitoring of brain function to detect EEG abnormalities shown to be related to NOWS and determine severity to guide pharmacological intervention. This study will focus on the initial prototyping and refinement of the hardware and software, as well as initial evaluations of its use.

There is an urgent need for improved medications to treat OUD. This project will test cebranopadol, a novel synthetic medication that interacts in a new way with the human opioid system as a safe and potentially effective alternative treatment for OUD. The research will test the safety and efficacy of cebranopadol in preclinical and clinical studies, toward guiding future research to support potential approval of this medication by the U.S. Food and Drug Administration.

Hospital inpatient stays due to opioid-related health problems are a reachable moment for increasing access to treatment with medications for opioid use disorder (MOUD). Hospitalized patients with opioid use disorder (OUD) are at particularly high risk for morbidity, mortality, and high medical costs in the U.S. This study will substantially inform the care management of OUD in hospitalized patients. The project includes a comparative effectiveness research trial and an implementation research trial, which will lead to models of broad dissemination for treatment approaches to this largely unaddressed population. They will examine whether (1) in hospitals with addiction medicine consultation services, hospital-initiated extended-release buprenorphine (XR-BUP), compared with other OUD medications, results in increased engagement in treatment with MOUD following hospital discharge and (2) training hospitals without such consultation services on best practices for initiating MOUD using consultation service hubs improves medication uptake in hospitals and increased MOUD treatment engagement following discharge.
