Funded Projects

This proposal would address barriers to the NP’s ability to prescribe buprenorphine by incorporating waiver education into NP final semester curriculum. The initial eight hours of training would be provided to students in a face-to-face classroom setting or via live video streaming. The remaining 16 hours would be completed by the NP students through online modules offered by the AANP. Trained NP students would be eligible for one year of peer-to-peer mentorship and inclusion in the MUSC Project ECHO tele-mentoring for new providers. Outcomes to be tracked would be the number of NPs trained who obtain their waiver and the number of individuals treated with MOUD by the NPs trained. Secondary data collected would offer insight into wavier obtainment process and determine need for mentorship for newly waivered providers.

Innovative interventions being conducted in emergency departments (EDs) for the treatment of opioid use disorders (OUD) have engaged more OUD individuals in treatment and saved lives. However, individuals who present to the ED following an opioid overdose, particularly those who have received naloxone reversal, are often resistant to accepting treatment. An innovative state-funded project called FAVOR Overdose Recovery Coaching Evaluation (FORCE) was initiated to try to address this problem wherein trained peer recovery coaches are called to the ED as soon as an opioid overdose victim is admitted. The proposed project will assess the feasibility and replicability of this model, assess whether the FORCE approach leads to more opioid overdose survivors entering formal substance use disorder treatment at one month compared to treatment as usual, and assess whether the FORCE approach leads to better retention in SUD treatment for OUD overdose survivors over time.

The project will apply natural language processing to a rich repository of suicide and other clinical electronic health record and vital statistics to detect opioid problem-related encounters in order to (1) explore the relation between suicide risk and opioid misuse and (2) test whether a Zero Suicide model?s intervention effect is moderated by opioid misuse and whether it can also help to reduce opioid-related harm. First, the team will extract opioid-related EHR data using a combination of diagnostic codes and natural language processing, validated by structured manual chart review using a standardized procedure. Next, they will analyze the interplay between suicide risk and opioid problems in encounters and patients within the repository. Third, they will assess the effect of Zero Suicide implementation on prospective fatal and non-fatal suicidal behavior in patients with an opioid problem and examine whether the implementation had an effect on the incidence of opioid-related outcomes, including intentional overdose.

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.

Researchers will develop an innovative three-dimensional (3D) model of acute and chronic nociception using human induced pluripotent stem cell (hiPSC) sensory neurons and satellite glial cell surrogates. They will develop a tissue chip for modeling acute and chronic nociception based on 3D hiPSC-based dorsal root ganglion tissue mimics and a high-content, moderate-throughput microelectrode array. Researchers will demonstrate stable spontaneous and noxious stimulus-evoked behavior in response to thermal, chemical, and electrical stimulation challenges. They aim to demonstrate sensitivity to translational control via ligand receptor interactions between neuronal and non-neuronal cell types. They also will demonstrate the quantitative efficiency and preclinical efficacy of our system by detecting known ligand-based modulators of translational control and voltage-gated ion channel antagonists in a sensitized model of chronic nociception. Researchers will leverage the high-throughput nature of our tissue chip model to screen Food and Drug Administration–approved bioactive compounds.

New medication treatment approaches are needed to help address the severe epidemic of opioid use disorder (OUD) and opioid overdose deaths in the U.S. Currently available medications, such as methadone, buprenorphine, and extended release injection naltrexone (XR-NTX; trade name: Vivitrol), are highly efficacious, but their effectiveness in practice is limited by poor adherence, with many patients stopping treatment prematurely and relapsing. The goal of this proposal is to develop an innovative long-acting subcutaneous implanted formulation of naltrexone, the O’Neil Long-Acting Naltrexone Implant (OLANI), toward FDA approval. Expected to produce naltrexone blood levels sufficient to block the effects of opioids for 6 months after implant, OLANI circumvents the need for adherence to monthly injections with XR-NTX and could represent an important new addition to the medical armamentarium for treatment of OUD.

With the exception of the Breathalyzer for alcohol, there is currently no available technology that can immediately identify neurologic impairment related to the use of licit or illicit drugs. The presently available methods for detecting opioids—which rely upon analysis of urine, blood, saliva, or hair—are expensive, time-consuming to implement, and can take days to deliver actionable information to meet the “fitness-for-duty” concerns of employers as well as the needs for immediate detection of drug use in the drug rehabilitation and public safety fields. This project intends to develop a non-invasive means of identifying temporary neurological impairment from prescription opioids using analysis of involuntary eye movements. The resultant biometric signature of opioid impairment will be incorporated into Zverex’s existing product library of oculomotor biosignatures, such as marijuana impairment and fatigue.

Buprenorphine (BUP) is an FDA-approved medication-assisted therapy (MAT) that improves outcomes and saves lives in patients with opioid use disorder (OUD). It is available in multiple dosage forms and routes of administration, including daily sublingual (SL) and buccal tablets and films, a monthly subcutaneous (SC) injectable, and a 6-month SC implant; however, these forms leave many patients untreated or undertreated. This product, in a partnership with Lyndra Therapeutics, aims to develop a once-weekly oral BUP dosage form for maintenance therapy for OUD, using a new oral dosage formulation developed by Lyndra. A long-acting oral BUP may address important limitations of current MATs by providing improved PK with less euphoria than SL, a patient- and provider-preferred route of administration, and an optimal dosing interval for improved patient adherence with the potential for cost-effective direct observed therapy.

There is a need for an opioid use disorder (OUD) treatment that can prevent relapse in detoxified subjects. Titan's proprietary subdermal implants can provide long-term, non-fluctuating therapeutic levels of drug continuously following a single office-based insertion procedure. The non-biodegradable solid matrix implant formulation virtually eliminates the risk of accidental drug dumping and associated serious toxicity, and its subdermal location assures patient compliance for the 6-month treatment duration. Nalmefene hydrochloride (nalmefene) is an opioid receptor antagonist approved for the management and reversal of opioid overdose. Prototype nalmefene implants inserted subdermally in rats delivered nalmefene continuously for months without any observable safety concerns. This proposed study will develop a 6-month implantable device that delivers nalmefene at a steady rate to prevent relapse to opioid dependence following opioid detoxification. This project will manufacture nalmefene implants, complete nonclinical safety and pharmacology studies, and conduct clinical studies in OUD subjects to support a New Drug Application.

Health care services for patients with both chronic pain and opioid use disorder are fragmented in the United States. To develop effective and feasible interventions for chronic pain and opioid misuse/disorder that can be implemented in both general medical and addiction treatment settings, this research examines two different care-delivery strategies. The first project will compare the effectiveness of a pharmacist-led, collaborative care approach for patients prescribed long-term opioids who have chronic pain and  opioid misuse/disorder compared to a pharmacist program with a cognitive behavior therapy-based pain self-management program. The second project will examine the effectiveness of a multimodal, interdisciplinary chronic pain management program that includes cognitive behavioral therapy, exercise, and stress management. With input from stakeholders and individuals with lived experience, this research has the potential to generate novel, reproducible, and scalable findings that addresses fragmented care delivery for co-occurring chronic pain and opioid misuse/disorder.

Hospital inpatient stays due to opioid-related health problems are a reachable moment for increasing access to treatment with medications for opioid use disorder (MOUD). Hospitalized patients with opioid use disorder (OUD) are at particularly high risk for morbidity, mortality, and high medical costs in the U.S. This study will substantially inform the care management of OUD in hospitalized patients. The project includes a comparative effectiveness research trial and an implementation research trial, which will lead to models of broad dissemination for treatment approaches to this largely unaddressed population. They will examine whether (1) in hospitals with addiction medicine consultation services, hospital-initiated extended-release buprenorphine (XR-BUP), compared with other OUD medications, results in increased engagement in treatment with MOUD following hospital discharge and (2) training hospitals without such consultation services on best practices for initiating MOUD using consultation service hubs improves medication uptake in hospitals and increased MOUD treatment engagement following discharge.

This health care data mining study analyzes existing Veterans Health Administration data sets to examine patient and organizational characteristics associated with buprenorphine termination during outpatient OUD treatment. This project will generate data useful for predictive modeling on how to implement targeted approaches to improve retention in OUD treatment. An objective is to identify patient, provider and system targets to reduce unnecessary or inappropriate discontinuation of buprenorphine care. These analyses are critical for establishing initial constructs to evaluate reasons for treatment discontinuation based upon patient, provider and system factors in different health care settings.
