Fibromyalgia (FM) is a chronic pain condition characterized by widespread musculoskeletal pain, tenderness, and stiffness associated with fatigue and sleep disturbance. The investigators have recently completed a trial that demonstrated efficacy of active transcutaneous electrical nerve stimulation (TENS) compared with placebo TENS or no treatment in women with FM. While physical therapists are trained in using TENS, it is underused in clinical practice. This application proposes a pragmatic clinical trial of TENS for patients with FM to determine if the addition of TENS to physical therapy (PT) reduces pain, increases PT adherence, and helps achieve functional goals with less drug use. This study will address the critical need for strategies to implement effective nonpharmacologic treatments for FM. Successful completion of this trial will provide generalizable effectiveness data for referring providers, physical therapists, and insurers and will inform future pragmatic trials of nonpharmacologic treatments conducted in PT practices.

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.

Quality implementation of evidence-based programs (EBPs) in community settings for youth is critical for reducing the burden of alcohol, tobacco and other drug (ATOD) use and its consequences. EBPs delivered in schools are an efficient way to reach large populations of young people, including those underserved by other settings, and reduce and prevent ATOD use. Yet youth rarely receive EBPs as intended in community settings, including schools. This training and research plan will prepare the investigator to become an independent scholar in the implementation of theories and frameworks to better understand factors related to program delivery—approaches to enhancing ATOD programs for youth in community settings. More specifically, the training will allow him to expand the application of Consolidated Framework for Implementation Research (CFIR) to inform approaches to enhancing effective EBP delivery. The proposed training and research plan extends current implementation research to focus applying implementation theories, frameworks and strategies in other community settings (schools) and on economic evaluation of implementation strategies. The results are expected to improve current efforts to deliver EBPs in diverse community settings and aid in applying evidence-based implementation strategies in the school context to ultimately reduce and prevent ATOD use among youth.

This study will evaluate novel strategies to reduce opioid use and pain in patients with end-stage renal disease receiving chronic hemodialysis (HD). Specifically, the study will examine the effect of nonpharmacologic (Acceptance and Commitment Therapy [ACT] and acupuncture) and pharmacologic (buprenorphine) interventions in HD patients who are receiving chronic opioid medications due to chronic pain and/or high pain interference. The study will enroll 720 HD patients across U.S. Hemodialysis Opioid Prescription Effort Consortium Clinical Centers to (1) determine the effectiveness of ACT and acupuncture compared with the control condition in reducing opioid dose and improving pain among HD patients; (2) identify the best adaptive intervention sequence for improved outcomes; (3) explore age, sex, and comorbidities as potential moderators of the response to the intervention; and (4) describe facilitators and barriers to the implementation of the intervention using in-depth, semi-structured individual interviews with intervention participants and providers.

There is a critical need to expand research infrastructure to develop, test, and implement new clinical interventions and evidence-based opioid use disorder (OUD) treatment into diverse clinical settings. The University of Utah’s Greater Intermountain Node (GIN) will expand the existing NIDA Clinical Trial Network’s (CTN) infrastructure by developing and testing innovative OUD interventions, expanding the settings for CTN research, and bringing new research acumen to the CTN. GIN brings expertise in three spheres of OUD research: (1) non-addiction health care settings, (2) large health systems of care, and (3) implementation science. GIN’s specific aims include (1) enhance CTN’s ability to conduct research in primary care and non-addiction care settings; (2) enhance CTN’s ability to conduct research within integrated systems of care with “big data” resources; and (3) enhance CTN’s implementation of science research to integrate and disseminate evidence-based addiction care into diverse non-addiction and health system targets.

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.

The overarching goal of the Greater Southern California Node (GSCN) of the National Drug Abuse Treatment Clinical Trials Network (CTN) is to expand access to and improve outcomes of treatments for substance use disorders (SUDs)—with a special emphasis on opioid use disorder (OUD). The specific aims of GSCN include the development of new research protocols, support of multi-site CTN projects, and dissemination of research findings. The GSCN research agenda includes four priority areas: (1) developing and testing effective interventions for OUD and related comorbidities, (2) applying implementation science to deliver and expand OUD treatment, (3) leveraging electronic health record systems and data science generation of innovative approaches to improve treatment for OUD, and (4) expanding OUD treatment access and utilization through mHealth and other technologies. The GSCN research agenda reflects its capacity to collaboratively expand CTN efforts to develop and implement innovative approaches to improve treatment for OUD.

Many chronic pain conditions are dependent upon activity of the sympathetic nervous system. Sympathetic blockade is used clinically in chronic pain conditions, but the clinical and preclinical evidence for this practice is incomplete. We propose that certain pathological pain conditions require intact sympathetic innervation of the sensory nervous system at the level of the dorsal root ganglion (DRG) and that release of sympathetic transmitters enhances local inflammation and leads to pain. Our preliminary data show large, rapid, and long-lasting reduction of pain behaviors and inflammatory responses following a"microsympathectomy" (mSYMPX) in both neuropathic and inflammatory pain models. Our aims are to: 1) characterize the effects of mSYMPX on pain and on local inflammation in the DRG; 2) explore the molecular mechanisms for sympathetic regulation of inflammatory responses in the DRG; and 3) assess the functional role of sympathetic transmitters in the sympathetically mediated inflammatory responses in the DRG.

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.

The orbitofrontal cortex (OFC) plays an important role in regulation of addiction, and OFC impairment from cocaine and opioids use leads to repetitive drug use. Brief optogenetic activation of the OFC reduces self-administration of drugs in neurobiology studies. However, the OFC is less accessible for noninvasive stimulation using direct transcutaneous current stimulation or transcranial magnetic stimulation. The small business EvON Medics LLC and Howard University have created a home-based olfactory pulsing prototype, called computerized chemosensory-based orbitofrontal cortex training (CBOT), using a high-fidelity chemosensory and computerized olfactory training approach to enable home-based neuromodulation of the OFC for treatment of opioid use disorder (OUD). A pilot feasibility study in OUD samples suggests that CBOT can minimize withdrawal symptoms, reduce drug cravings, enhance positive affect, and reduce rate of positive urine drug tests. The project seeks to establish CBOT stimulation parameters needed to maximally improve outcome inference and emotion regulation in OUD.

New Hampshire can anticipate as many as 1,000 infants born with prenatal opioid exposure each year. Pain management is complicated for pregnant women with opioid use disorder (OUD), and undermanagement of pain is a strong risk factor for relapse. Contemplative interventions, such as yoga and mindfulness, may reduce risks for relapse for pregnant and parenting women with OUD. This project represents a partnership with New Hampshire stakeholders to develop and pilot evaluation of a trauma-informed yoga and mindfulness relapse prevention intervention (Mindful Moms in Recovery: MMORE). It aims to: 1) identify needs and areas of adaptation of trauma-informed yoga and mindfulness-based relapse prevention protocols through formative work with pregnant and parenting woman; 2) develop an integrated 10-session intervention protocol with iterative feedback from client stakeholders; and 3) evaluate feasibility, acceptability, and efficacy trends of MMORE in a pre-post pilot with pregnant women.

Deaths from opioid overdose are highly preventable with early detection and administration of naloxone, but overdose victims often die because they are alone or among untrained or impaired bystanders and thus do not receive timely resuscitation. There is an urgent, unmet need for a low-barrier, easily scalable solution that can identify opioid overdoses in real time and rapidly connect victims to naloxone therapy. This proposal seeks to commercialize an innovative overdose detection software product that can be downloaded on any commodity smartphone and can detect opioid- induced respiratory failure (i.e., overdose) and summon help. The software-only product, SecondChance, converts a smartphone into a short-range active sonar system capable of monitoring breathing and detecting overdose.

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.
