Funded Projects

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.

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.

A large number of probationers/parolees with opioid use disorder have limited access to effective treatment. This study is the first random clinical trial in the United States that will assess the effectiveness of buprenorphine treatment using MedicaSafe, a system composed of secure pre-packaged buprenorphine/naloxone cartridges, designed to be dispensed by a SmartKey device that enables clinicians to track patient adherence. The study will initiate treatment at a community corrections office compared to referral to a community program. The public health impact of the proposed study would be widespread, as this model of care could be implemented throughout many areas of the United States with high rates of opioid use disorder in their probation/parolee populations that lack access to methadone treatment.

Rates of neonatal abstinence syndrome have reached a staggering 6.5 per 1,000 births nationwide, creating an urgent need to identify how in-utero exposure to opioids and associated risk factors influence the developing brain. A multidisciplinary team will address these challenges in Oregon, a state particularly hard hit by the opioid epidemic. Through linking sites, the impact of the Phase I project is enhanced and will provide critical information to support a national-level effort for Phase II of the HEALthy Brain and Child Development Study. Aim 1 will develop, implement, and evaluate innovative recruitment and retention strategies for high-risk populations. Aim 2 will address anticipated challenges of the planned Phase II study by implementing and evaluating a multi-site, standardized research protocol including multimodal MRI of placenta, fetus, neonate, and 24-month-old brain; biospecimen collection; and assessment of substance use and other key domains. Aim 3 will evaluate data acquisition, processing, and statistical considerations to maximize data quality, usability, and integration across sites.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative model 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 Boston Children’s Hospital study site is in Massachusetts, which has the fifth highest rate of opioid use in the U.S., and twice the U.S. average incidence of opioid use disorder in delivering mothers.

FDA-approved medications for treating opioid use disorder are effective, but there is a significant unmet need for alternatives, especially relapse prevention. NIDA and the FDA have encouraged investigators to expand the range of therapeutic outcomes, beyond measurement of abstinence. Insomnia is a clinically significant, but understudied, correlate/predictor of relapse to substance use. Yet most medications for treating insomnia have limited efficacy and can produce side effects. The orexin (OX) system plays a key role in sleep and substance use, offering a promising avenue for study. This project will address whether OX-1/2 antagonism is a mechanism that can directly improve outpatient opioid abstinence, or whether OX antagonism corrects sleep deficiencies and indirectly improves opioid abstinence. Specific aims are to determine whether nightly treatment with the OX-1/2 antagonist suvorexant, relative to placebo, 1) increases outpatient opioid abstinence and 2) improves sleep efficiency on the residential detoxification unit. The study will also determine 3) whether improved sleep efficiency predicts greater opioid abstinence (regardless of group assignment).

High relapse rates among people with opioid use disorder (OUD) indicate that addiction involves appetitive pathways. Peripheral stimulation of the glucagon-like peptide-1 receptor (GLP-1R) “satiety” pathway could reduce heroin seeking and taking. Pretreatment with a GLP-1R agonist reduces heroin taking, seeking, and drug-induced reinstatement in rats. This project tests whether GLP-1R agonists can reduce relapse in humans with OUD. A pilot study will be conducted to determine whether once-daily treatment with the shorter acting GLP-1R agonist, liraglutide, can safely and effectively reduce cravings among OUD patients. Animal models will be used to test the efficacy and safety of a longer-acting GLP-1R agonist, semaglutide, and then a clinical trial will be conducted to test whether semaglutide will reduce relapse and use in animal models. If successful, the study will show that treatment with GLP-1R agonists can safely and effectively reduce opioid craving, seeking, and relapse.

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.

The nation’s opioid epidemic remains a public health emergency, marked by high rates of opioid use and misuse among adults and a correlated rising incidence of neonatal opioid withdrawal syndrome (NOWS) in infants exposed to opioids before they are born. There are currently no pharmacotherapies approved by the Food and Drug Administration (FDA) for the treatment of NOWS. This research will complete manufacturing and clinical trial activities to evaluate and support FDA approval of a pediatric-appropriate formulation of lofexidine, a non-opioid medication approved for mitigation of opioid withdrawal symptoms in adults, as a first line-therapy in NOWS patients through two clinical trials to (1) identify an optimal dosing regimen of lofexidine for treatment of NOWS, and (2) evaluate the risks and benefits of its use in improving withdrawal symptoms, limiting infant exposure to other off-label narcotic medications and shortening the infant’s overall stay in the hospital.

This study will determine the feasibility of a multifaceted approach to recruitment of normal and high-risk pregnant women and their children. Three inter-related tasks will support this comprehensive feasibility study. First, an interdisciplinary summit will occur early in the study focused on how best to mitigate risks and maximize benefits to children and families recruited in a future cohort. Second, the feasibility of a multi-faceted recruitment strategy will be assessed. Third, select pregnancy and birth assessments will be collected from recruited participants in this feasibility study while leveraging data across early childhood from existing resources, to inform Phase II study planning. This Phase I of the FL-DECADE study will provide valuable planning and feasibility data to be used for the national efforts to build a large, prospective cohort.

One novel approach to address the opioid crisis is predicting the likelihood of retention in treatment for opioid use disorder (OUD) by assessing someone?s risk of early departure from treatment. Current methods rely on providers intuition to identify when an individual is at risk of leaving treatment early in order to intervene. This intervention, when it happens, often comes too late. Mobile health (mHealth) and Machine Learning (ML) predictive analytics offer a new opportunity to personalize OUD treatment, improve retention in OUD care, and mitigate the risk of relapse and overdose episodes. Project Motivate will combine physiological and behavioral data from disparate sources in order to predict when an individual is at risk of early departure from OUD treatment. If successful, results of the study will save lives, and lower medical costs, municipal emergency response costs, recidivism, workplace accidents, lost workplace productivity and costs to families.

Decreasing opioid dosing faster than advised by clinical recommendations often leaves chronic pain unaddressed and may increase the risk of overdose and suicide compared to continuing long-term opioid treatment. Continued, long-term use of opioids after surgery by individuals who use opioids increases the risk of postoperative complications, opioid use disorder, and death. Surgery is a critical point-of-care moment for health care providers to interact with patients who use opioids about continued opioid use when harms outweigh benefits. This project will test of the Motivational Interviewing and guided Opioid Tapering support (MI-Opioid Taper) strategy, with or without a medication that reduces anxiety and relieves pain, at four geographically diverse hospitals across the nation.

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.
