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.

The Data Coordinating Center (DCC) of the Early Phase Pain Investigation Clinical Network (EPPIC-Net) will be the data and biospecimen manager for pain research within the HEAL Partnership. As such, it will host, manage, standardize, curate, and provide a sharing platform for data and biospecimens for HEAL initiatives, such as the Acute to Chronic Pain Signatures initiative and the BACPAC, in addition to EPPIC-Net studies. The DCC will develop and maintain a databank for depositing data, will link these data with a repository for biological samples, and will create a platform for teams to work together to analyze and interpret data. Further, the DCC will provide leadership in the statistical design and analysis of EPPIC-Net studies and will deploy advanced systems and processes for data collection, management, quality assurance, and reporting. The DCC will create, sustain, and continually advance a robust organization for the rapid design, implementation, and performance of high-quality rigorous Phase II clinical trials to test promising therapeutics for pain.

Emergency department (ED)-initiated buprenorphine/naloxone (BUP) with referral for ongoing BUP is superior to referral alone in engaging patients with untreated opioid use disorder (OUD) in treatment at 30 days and is cost-effective. However, logistical barriers exist in translating research into practice. New BUP formulations such as the extended-release injectable BUP (CAM2038, XR-BUP) hold promise in addressing many of the barriers more effectively than sublingual buprenorphine (SL-BUP) by treating the patients’ symptoms for up to seven days. This study will recruit, train and provide resources to 30 ED sites throughout the U.S. using implementation facilitation strategies to address stigma and provide ED-initiated BUP for patients presenting with OUD who are not receiving medications for OUD. Once implementation is adequately achieved, the sites will conduct a randomized controlled trial (RCT) to compare the effectiveness of SL-BUP versus XR-BUP on ED patients’ engagement in formal addiction treatment seven days after their ED visit. In addition, in an ancillary component of the study, the use of XR-BUP will be assessed in ED patients with Clinical Opioid Withdrawal Scale (COWS) scores of

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.

This training and dissemination project will develop an office-based buprenorphine treatment module for primary care, including the algorithm for buprenorphine treatment and integration of OUD measures; assess the acceptability of the OUD module; evaluate the impact of the OUD module on screening and identification rates of problem opioid use and successful initiation and maintenance rates of buprenorphine in primary care; assess barriers to implementation of buprenorphine treatment and methods for overcoming these barriers in the network partner clinics; and develop a strategy to refine and more broadly implement opioid problem use and OUD treatment.

Substance use disorders (SUDs) can have devastating consequences for people with serious mental illness (SMI). SUDs can increase morbidity and mortality and are associated with higher healthcare and social costs, homelessness, and incarceration. Unfortunately, despite the availability of effective treatments, most individuals with co-occurring SMI and SUD (COD) never receive SUD treatment. We propose to evaluate system, provider, and patient-level facilitators and barriers and develop an implementation strategy and toolkit to promote the use of medication-assisted treatment (MAT) for people with COD. Aims 1–3 seek to assess organizational capacity (at the system and provider level); organizational readiness (at the provider level); and perceived needs, attitudes, and preferences (at the patient level) to identify barriers and facilitators. In Aim 4, we will use findings from Aims 1–3 to guide development of the implementation strategy and toolkit, using stakeholder input and a systematic process for strategy development.

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.

Dorsal root ganglion (DRG) neuronal hyperexcitability is central to the pathology of neuropathic pain and is a target for local anesthetics, even though the efficacy of local anesthetic patches has been mixed. The coordinated movement of ion channels, especially voltage-dependent sodium channels, from intracellular pools to the sites of nerve injury has been suggested to be an underlying cause of electrogenesis and ectopic firing in neuropathic pain conditions. Recent studies identified Magi1 as a scaffold protein responsible for sodium channel targeting and membrane stabilization in DRG neurons. This project will determine whether reducing the expression Magi1 could disrupt intracellular trafficking of sodium channels in DRG neurons under neuropathic injury conditions, and could therefore serve as a potential therapeutic target for neuropathic pain.

Effective treatment for OUD has been shown to improve patient outcomes and reduce health care costs; however, evidence of this effect in primary care settings is severely limited. The health economic findings from this study will supplement the parent PROUD trial’s results regarding clinical effectiveness and implementation outcomes and provide critical contextual information for health systems and other health care stakeholders. The study will evaluate the economic viability of the PROUD collaborative care model for OUD—that is, from the perspective of the health care sector, to what extent do the downstream cost savings associated with improved patient outcomes offset the additional costs of the PROUD intervention? The specific aims are to (1) estimate the start-up and ongoing management costs of the PROUD intervention, (2) assess costs associated with health care utilization for patients who receive primary care treatment in PROUD and usual care clinics and have been identified with recognized OUDs before clinic randomization, and (3) estimate the economic value of the PROUD intervention, measured as net monetary benefit (NMB, incremental benefit minus incremental cost), from the health care sector perspective.

This study will develop and test the feasibility of implementing guidelines on workplace policies to reduce prescription opioid use, decrease chronic opioid use, promote recovery from opioid use disorder, and improve health-related employment outcomes. The researchers will develop and test these guidelines among construction workers. This project will provide critical information to design and conduct a randomized trial to implement and evaluate insurance and employment policy guidelines among labor-management health funds in the building trades. Aim 1 will identify current best-practice health care and employment policies to prevent health and employment consequences of opioid use. Aim 2 will characterize the opioid problem in construction and adapt best-practice healthcare and employment policies to the unique needs of the construction industry. Aim 3 will evaluate the feasibility of implementing workplace opioid guidelines in the construction trades and will define and collect measures of implementation and effectiveness.

Effective treatments are elusive for the majority of patients with neuropathic pain. Reactive oxygen and nitrogen species (ROS/RNS) are involved in neuropathic pain, because they drive mitochondrial dysfunction, cytokine production, and neuronal hyperexcitability; therefore, stimulation of endogenous antioxidants is predicted to simultaneously resolve multiple neuropathic pain mechanisms. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that is a potential therapeutic target because it regulates the expression of a large number of endogenous antioxidant-related genes and can be activated with a single drug. This project will test the hypothesis that Nrf2 activation increases multiple endogenous antioxidants, therefore reversing neuropathic pain behaviors and counteracting neuropathic pain mechanisms that are driven by ROS/RNS and could provide an effective pain therapy, with minimal abuse/addictive potential.

From 2009 to 2013, the utilization of the Schedule II opioids codeine, OxyContin, and fentanyl declined significantly, down about 14 percent for all three drugs. In sharp contrast, the use of tramadol, a Schedule IV controlled substance, increased by 32.5 percent. Schedule IV substances have lower potential for abuse and harm than Schedule II substances, and the fortuitous trend to tramadol has reduced the use of the relatively unsafe Schedule II opioids dramatically. However, tramadol is less effective in some individuals with a particular gene variant that makes them unable to metabolize it well. A new analgesic, omnitram, uses similar mechanisms to tramadol but is not as dependent on this gene. This SBIR Fast-Track project will conduct a Phase 1 clinical trial of Omnitram in normal human subjects. Success in this in-patient Phase 1 clinical trial will provide direct support for Omnitram’s continued clinical development toward FDA approval.

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.
