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 4-7.

Correctional settings have the potential to serve as key players in linking individuals with opioid use disorder (OUD) to treatment and health services upon release. Many individuals with OUD are being treated with medications, but these efforts will be ineffective if they fail to connect people to OUD treatment upon release. The Transitions Clinic Network (TCN) program provides enhanced primary care and OUD treatment for people recently released from incarceration. In TCN, formerly incarcerated community health workers are embedded within primary care teams and address social determinants of OUD, provide social support, help patients build trust in the health system, and advocate in interactions with the criminal justice system. This study will assess the effectiveness of the TCN: Post Incarceration Addiction Treatment, Healthcare, and Social Support (TCN PATHS) intervention versus referral to standard primary care on opioid treatment cascade outcomes and whether housing, food access, criminal justice contact, and social support mediate this association.

There are currently no FDA-approved treatments for cocaine use disorder (CUD) or co-occurring substance use disorder. High relapse rates pose a major obstacle to treatment, and this is due in part to the way that high drug cravings reduce individuals’ cognitive flexibility in situations where they are stressed or exposed to drug-related cues. These effects appear to be stronger in women with CUD than in men. Building on preliminary data that a drug called Guanfacine reverses these effects in women, but not in men, this 3-year pilot clinical study will test whether Guanfacine will reduce cocaine use and increase abstinence and will use laboratory challenges to determine whether it reduces cravings and enhances cognitive flexibility in stressful or drug-cue-related situations.

Compared to people with stable housing, individuals experiencing homelessness are more likely to use both fentanyl and stimulants and experience drug-related harms. This project will examine fentanyl-stimulant polysubstance use patterns and how they evolve over time in response to changes to housing status. It will also assess use of overdose prevention and substance use disorder treatment interventions in homeless individuals who use both fentanyl and stimulants, including how polysubstance use patterns shape their risk of overdose over time. This research will also interact with community stakeholders toward translating the findings into future research, policy, and program recommendations.

This study will conduct preclinical and clinical assessments of the NMDA modulator NYX-783 for treatment of opioid drug-seeking and relapse to opioid use disorder (OUD). NYX-783, a novel small molecule being developed by Aptinyx, has shown evidence of safety/tolerability in Phase 1 studies and is currently in Phase 2 trials for post-traumatic stress disorder. This project will test the safety, tolerability, and pharmacokinetics (PK) of NYX-718 in morphine-maintained patients in residential settings and then conduct a combined inpatient (safety/tolerability/PK) / outpatient (preliminary efficacy) study testing NYX-783’s effects on opioid use and relapse, stress/cue reactivity, craving, and quality of life in OUD subjects maintained on standard extended release naltrexone over a 10-week period. Successful completion of these studies will set the stage for larger scale Phase 2/3 studies of efficacy in OUD that will ultimately be required for FDA approval of NYX-783 for the treatment of drug-seeking and relapse in OUD.

Opioid use disorder (OUD) is a chronic and relapsing brain disease that affects over 2 million Americans. Despite effective evidence-based treatments in the form of behavioral interventions and FDA-approved medication for addiction treatment (MAT), relapse rates are high. The Collaboration Linking Opioid Use Disorder and Sleep Study will investigate patients on MAT to elucidate potential causal mechanisms between sleep deficiency and OUD. The aims of this study are to 1) test whether there are different neurocognitive connectivity patterns between patients with adequate vs. deficient sleep in brain systems involved in addiction and assess the extent to which these “neural fingerprints” predict ongoing opioid use; 2) evaluate the potential biologic, psychiatric, and pharmacologic mechanisms that explain the causal pathway between sleep deficiency and opioid use; and 3) test ecologic factors such as psychosocial, family, and neighborhood contextual factors associated with OUD and their contribution to sleep deficiency among patients in MAT.

Women with opioid use disorder (OUD) are disproportionately impacted by physical, sexual, and psychological intimate partner violence and posttraumatic stress disorder (PTSD). Yet, treatment approaches that address all these conditions together in OUD treatment settings are lacking. To address this gap, this project will evaluate delivery of two evidence-based interventions to address PTSD (Present-Centered Therapy+ and Helping to Overcome PTSD through Empowerment) for women seeking OUD treatment who have experienced intimate partner violence. It will also determine if integrated treatment can help retain the women in medication treatment for OUD.

Most opioid misuse begins during adolescence and young adulthood. Adolescence is the best time for prevention interventions in settings like school-based health centers (HCs), yet few programs focus on preventing initiation of opioid misuse. This study harnesses the power of video game interventions and incorporates components of effective substance use prevention programs to develop an evidence-informed intervention to prevent the initiation of opioid misuse in adolescents. In partnership with the national School-Based Health Alliance (SBHA), researchers will develop and test a new video game intervention, PlaySmart. It will build on our previous video game intervention that has demonstrated efficacy in improving attitudes and knowledge related to risk behaviors. The study will evaluate the game in a randomized controlled trial (RCT) in 10 school-based HCs and examine strategies for implementing PlaySmart in school-based HCs nationally. This research has considerable potential for wide implementation, reach, and impact on high-risk adolescents through school-based HCs.

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.

In 2018, new opiate prescribing limits (SB 273) were implemented across West Virginia to combat the opiate misuse epidemic. This study will utilize quantitative and qualitative measures to determine the effect of the recent opiate prescription laws in West Virginia, how a change in policy affects the opiate misuse epidemic, and how communities may apply this knowledge more broadly. The research team will: 1) collaborate with the West Virginia Board of Pharmacy to ascertain changes in opiate prescribing habits before and after the start of SB 273 using an interrupted time series methodology, and 2) achieve broad and deep understanding of how SB 273 has affected prescribing practices and experiences amongst primary care physicians, specialists (pan physicians, surgeons, emergency room physicians, etc.), and patients who currently or previously utilized opiate medications.

Mortality rates in Appalachia have progressively increased over recent years, in contrast to decreasing mortality rates observed in the remainder of the U.S. The West Virginia Clinical and Translational Science Institute (WVCTSI) was created in 2012 through the initial Clinical and Translational Research (CTR) award and has subsequently formed a well-connected, statewide research network, creating the infrastructure to address the substantial health disparities that exist in West Virginia. WVCTSI is now well positioned to attain the goals of this renewal application that include: 1) building sustainable research infrastructure that substantively contributes to improving West Virginia health outcomes by 2022; 2) recruiting the next generation of clinician scientists and translational researchers that excel in team science and are positioned for long-term success; and 3) actively engaging with multiple stakeholders that include communities, medical providers, and policy makers to drive research that improves the health of West Virginians.

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).
