The opioid overdose epidemic is increasingly affecting urban, poor and predominantly minority populations in the U.S., including Washington, D.C., as indicated by rapidly increasing overdoses clustered in medically underserved, economically disadvantaged, largely African American areas of the District and many of the nation’s other largest cities. This study seeks to (1) develop, implement and conduct a preliminary evaluation of an integrated, community-based collaborative care model, employing peer recovery coaches and telepsychiatry services, to improve utilization and effectiveness of MOUD in Federally Qualified Health Centers (FQHCs) and (2) use a community-based participatory research approach to develop, implement and conduct a preliminary evaluation of outreach, engagement and recovery support interventions in nontraditional community settings (e.g., grassroots community groups, churches or religious organizations, soup kitchens, black barber shops or nail or hair salons).

The Planning for the HEALthy Early Development Study will contribute to the design and recommended protocol for a future large-scale, multi-site research study to prospectively examine human brain, cognitive, behavioral, social, and emotional development of children beginning prenatally through ages 9–10 and to determine the impact of maternal pre- and postnatal substance use on short- and long-term development of children. The planning study will link investigators across 6 research sites who have complementary experience and expertise in the areas that are essential to designing the study. Planning activities will be accomplished using a coordinated set of 10 working groups. By the end of the planning phase, the 6 consortium sites will have produced and tested a recommended protocol for the future multi-site study and will have established feasibility of carrying out the study protocol at each of the 6 linked sites.

Less than half of youth in the juvenile justice system who meet the criteria for substance use disorders (SUD) have ever received treatment, and less than one third of those received treatment while under community or correctional supervision. SUDs during adolescence can lead to significantly longer periods of substance use, more severe offending, and penetration in the justice system. The Translational Research on Interventions for Adolescents in the Legal System (TRIALS) cooperative is intended to develop and test implementation strategies and associated measures to improve the continuum of substance abuse and HIV prevention and treatment services delivered to youth under juvenile justice supervision.

Despite increased efforts to understand the neurodevelopmental sequelae of in utero opioid and other substance exposure on long-term behavioral, cognitive, and societal outcomes, important questions remain, specifically, 1) How is brain growth disrupted by fetal substance and related pre- and post-natal exposures? and 2) How are these disrupted growth patterns causally related to later cognitive and behavioral outcomes? This project seeks to formulate an approach to addressing these key questions and decipher the individual and cumulative effect of these intertwined pre- and post-natal exposures on child neurodevelopment. First, researchers will address the legal, ethical, and mother-child care and support concerns implicit in this study. Next, they will integrate across our areas of neuroimaging expertise to develop, implement, and harmonize a multi-modal MRI and EEG protocol to assess maturing brain structure, function, and connectivity. Finally, researchers will develop and test advanced statistical approaches to model and analyze this multidimensional and longitudinal data.

Medications for the treatment of opioid use disorders (MOUD) are effective at reducing opioid use, opioid overdose risk, and opioid-related deaths; however, retention and adherence to MOUD treatment, particularly buprenorphine (BUP), are discouragingly low. The objective of the current research is to adapt and extend a cognitive behavioral therapy-based short message system (SMS) intervention (TXT-CBT) to address MOUD treatment retention and adherence using the imFREE (Interactive Messaging for Freedom from Opioid Addiction) platform. imFREE builds upon the efficacious SMS-based TXT-CBT intervention, with content addressing retention and adherence to BUP, including mitigating risk factors for dropout, and features to notify social and provider support contacts in the face of treatment discontinuation and/or other indicators of relapse and overdose risk. By providing support to maximize BUP treatment adherence, coupled with skills to prevent relapse, imFREE may provide a cost-effective, easily deployable strategy for OUD treatment and prevention of overdose deaths.

EicOsis is developing a first-in-class analgesic with efficacy against neuropathic pain that will reduce or replace the need for opioids and thus potentially prevent opioid use disorder (OUD). The target of the small molecule inhibitor EC5026 is the soluble epoxide hydrolase, a master regulatory enzyme that modulates the activity of endogenous bioactive lipids. The study will reach the next steps in clinical human clinical trials with EC5026 through additional preclinical studies to expand the efficacy into models of chronic pain conditions. Additionally, detailed pharmacokinetic, metabolism, and distribution studies are proposed that will provide the required information to optimize drug formulation and for advanced clinical trials examining efficacy in humans. EicOsis is meeting current development goals, and EC5026 is well positioned to meet the urgent need of reducing opioid use.

Newborn Abstinence Syndrome, which results from maternal opioid drug use prior to birth, is a serious condition that affects approximately 6% of all neonates born today in the U.S. and which is increasing rapidly in incidence because of this epidemic. Availability of a rapid screening test that can be administered at the point of care to all neonates would allow for early intervention, reducing costs of treatment and reducing pain and suffering for this vulnerable and helpless patient population. Providing a platform to accurately monitor actual levels of these drugs and their metabolites in such patients would allow better-controlled use of these pain management treatments, personalized to the needs of the individual neonate, and would reduce the probability of addiction and resulting complications, which include deleterious neurological effects. The purpose of this FastTrack SBIR project is to expand upon preliminary results that a device can sensitively and accurately detect opioids and their primary urinary metabolites in one-microliter urine samples, in less than a minute after sample introduction into the device, and adapt the device into a point-of-care instrument for use in hospitals, clinics, and other venues in which such tests are likely to be deployed.

As of 2012, an infant with neonatal abstinence syndrome (NAS) was born every 25 minutes in the United States, accounting for more than $1.5 billion in national health care expenditures. These infants frequently require hospital stay in a neonatal intensive care unit (NICU), with an average hospital stay of 25 days at an average treatment cost of $66,000. Treatment of NAS usually follows a multimodal regime based on drug therapy with an oral morphine solution, mostly in combination with a sedative, but there is a need for nonpharmacological approaches. This project will test a transcutaneous auricular neurostimulation device to help NAS babies recover from opioid withdrawal without harmful side effects. The non-invasive, auricular neurostimulation device will be placed around the ear (similar to a hearing aid), and stimulation will be delivered transcutaneously.

Opioid agonist therapy (OAT), such as buprenorphine/naloxone (BUP/NAL), is proven effective against opioid use disorder (OUD), but poor medication adherence is a major barrier. This project aims to substantially increase adherence to oral BUP/NAL with Pillsy, a smart technology platform, which acts like a digital medication coach, providing education and reminders using a mobile app, text messages, and automated phone calls. The platform is built around a Bluetooth-based smart pill bottle cap that automatically tracks doses and timing, and sends intelligent reminders to create a unique feedback loop, which allows constant optimization of the incentive/reminder messages to meet user needs to increase adherence. A dashboard enables providers to easily track medication use and patient engagement. The Pillsy platform only nominally increases the cost of oral BUP/NAL treatment, and physicians can bill for monitoring time (CPT code 99091). The project team will adapt the current Pillsy platform and perform a randomized efficacy trial of BUP/NAL adherence.

Poor medication-assisted treatment (MAT) retention disproportionately affects low-income racial/ethnic minority individuals with opioid use disorder (OUD) and increases risk for relapse; therefore, evidence-based interventions are needed to improve MAT retention. Peer recovery coaches (PRCs), trained individuals with experiences with substance use disorder, may be uniquely suited to address common MAT retention barriers among underserved populations, including stigma, challenges navigating services, housing instability, and other structural and psychosocial factors. Preliminary work by the research team suggests that behavioral activation (BA) by PRCs may be a feasible, scalable reinforcement-based approach for improving MAT retention for low-income minority OUD individuals. The study builds upon the research team’s formative work to adapt and evaluate the effectiveness and implementation of a PRC-delivered BA intervention (Peer Activate) to improve MAT retention for low-income, minority individuals with OUD.

Opioids have been significantly over-prescribed and are associated with numerous deaths, resulting in the nation’s current opioid crisis. The FDA recently approved the ?2 adrenergic agonist lofexidine as a non-addictive, non-opioid treatment for opioid use disorder (OUD), but there is a continued, urgent need to develop additional pharmacological alternatives to address both pain and OUD. The psychoactive, natural product, Mitragyna speciosa (kratom), has triggered significant interest in this space because Mitragynine, its main alkaloid, can interact with both mu opioid and ?2 receptors, offering a totally new approach for treating OUD. This project involves the synthesis and research of a series of Mitragynine analogs to better understand the pharmacological mechanisms that underlie Mitragynine’s opioid and adrenergic activities. If successful, this project will result in templates for the design of novel opioid receptor ligands. This advance would greatly improve the knowledge of interactions of these structurally novel compounds with opioid receptors and facilitate the development of these ligands as treatments for OUD.
