The objective of the HBCD PRELUDE (Prenatal Experiences and Longitudinal Development) multi-site consortium is to characterize typical brain development from birth through childhood. All sites in this consortium will measure the influence of key biological and environmental factors on child social, cognitive, and emotional development. Researchers will assess how prenatal exposure to opioids and other substances, as well as other adverse environmental factors, affect brain development and other child health outcomes. The Vanderbilt University site will enroll a diverse sample of mother-infant dyads reflective of the racial, ethnic, and economic composition of the demographics of Tennessee, including rural areas dramatically affected by the opioid crisis.

Neonatal Opioid Withdrawal Syndrome (NOWS) is a condition that occurs when newborns are exposed to opioids during pregnancy. Symptoms often include tremors, excessive crying, sleep deprivation, and swallowing difficulties. Cases are rising, with a newborn affected by NOWS approximately every 15 minutes. Currently, healthcare providers in the United States lack standard, evidence-based treatments for NOWS. 

This project is part of a multi-center, randomized controlled clinical trial that directly compares NOWS treatments—morphine, methadone, and buprenorphine—and takes into account other types of non-drug therapies, such as behavioral interventions. The goal is to generate results that can inform clinical practice guidelines and give newborns with NOWS the best start possible. 

The University of Alabama at Birmingham routinely treats newborns with NOWS and has been part of NICHD’s Neonatal Research Network (NRN) for more than 25 years. The center has an excellent track record of enrollment in clinical studies, with successful follow-up to 2 years of age and beyond.

The excruciating multiday experience of opioid withdrawal syndrome (OWS), is exacerbated by the opioid antagonist drugs naloxone and naltrexone. This industry-academia collaboration will explore the potential of the glutamate AMPA receptor antagonist Tezampanel (TZP). Animal studies have shown reduced hyperactivity in brain circuits involved in OWS, without relying on direct stimulation or antagonism of the opioid system ,and has already been delivered to over 500 human subjects and found to be safe for a potential migraine indication. This proposal will build up the evidence needed to apply for and conduct open label and blinded placebo-controlled human trials of TZP safety and efficacy for OWS. If successful, this project will allow planning for a pivotal registration trial for TZP for OWS, and as a transitional treatment to long-term recovery on naltrexone and help us stem the tide of the opioid crisis.

While advances in cancer treatment have increased survival rates, these patients often suffer from chronic cancer pain. Prescription opioids are often prescribed during active cancer treatment, but their long-term use for chronic cancer pain is associated with risk for opioid use disorder and risk for stigmatization associated with emotional distress, suboptimal health behaviors and coping strategies, and difficult patient-provider communication. This study aims to conduct qualitative interviews exploring prescription opioid and chronic pain stigma in cancer survivors with moderate-to-severe pain, caregivers, and clinicians who treat patients with chronic cancer pain, including oncologists, primary care providers, pain management specialists, and palliative care physicians. An analysis of potential contributors to stigma in cancer survivors will be completed to support development of multi-level behavioral interventions to reduce stigma and explore long-term health outcomes from such interventions.

Buprenorphine-naloxone is known to work for the treatment of Opioid Use Disorder (OUD). However, despite its success in treating OUD, retention for these kinds of medication-assisted treatments (MATs) for OUD is notoriously low, having a dropout rate of approximately 50 percent within the first 6 months. One factor known to negatively impact a person?s adherence to treatment is stigma. This includes, not only stigma associated with having OUD, but also that of multiple stigmatized identities, including stigma associated with race. The goal of this supplement award is to decrease OUD- and race-related stigma in low income African American communities using a Behavioral Economics Stigma Reduction intervention that functions at the intrapersonal, interpersonal, and community levels. The investigators will work at the individual level to address stigma in untreated individuals who present with OUD at local community or faith organizations through stigma reduction counseling and tangible rewards for treatment uptake. To assess the interpersonal stigma, referred family members or support persons of these individuals will also be enrolled to receive stigma reduction and supportive skills counseling. Finally, a stigma reduction campaign will be developed and administered to the community via social media and billboards. Community members? substance use stigma will be compared before and after the campaign.

The project will address gaps in both risk identification and clinical management by utilizing comprehensive clinical data from a mature health information exchange containing more than 2.3 million patients across the spectrum of clinical care (hospitals, primary care, specialty care, community health centers, urgent care) to develop a statistically robust method to measure suicide risk associated with prescription opioid use. First, the team will couple data fusion techniques with machine learning-based approaches in identifying the clinical and demographic characteristics associated with elevated risk of suicidal behavior among prescription opioid users. Second, the team will develop clinical profiles of patients with higher risk of suicidal behavior associated with prescription opioids, and to incorporate these profiles in a clinical decision support platform that can be used for identification and intervention at the point of care. The clinical decision support tool developed under this proposal will provide a generalizable platform that could be extended to other more conventional opioid related outcomes such as OUD and overdose.

Among the more than half-million adults entering addiction treatment for prescription opioid abuse every year, 50%-60% report co-morbid chronic pain, and 80% report that pain triggers relapse. Individualized/self-stigma among adults with substance abuse has been shown to lead to delayed recovery, increased relapse and reduced treatment-related attendance. Stigma may induce significant burden on patients with OUD and chronic pain and there may be unique characteristics of stigma for this population due to the overlap between medical treatment and substance abuse. Multiple sources of stigma may be imposed including internalized/self-stigma as well as intragroup/peer-to-peer (?horizontal?) stigma whereby peers impose stigma upon each other based on the type and severity of past drug use. Furthermore, stigma could be ?vertical? in that stigma may be enacted by health care providers or by treatment center staff. However, there is notably a lack of research and related assessment tools to measure these multidimensional facets of stigma, particularly in patients with OUD and chronic pain. The investigators will utilize a mixed-methods approach to evaluate internalized/self-stigma, anticipated/expected stigma and enacted stigma using existing standardized surveys, and to describe horizontal and vertical stigma in individuals with OUD and pain at multiple sites. In addition, the investigators will integrate the quantitative and qualitative information to help inform modifications to the psychotherapy component (I-STOP) of the parent award intervention, which would then also target multidimensional stigma in patients with OUD and chronic pain.

Neonatal opioid withdrawal syndrome (NOWS) has emerged as a tragic by-product of the opioid epidemic. Newborns whose mothers used opioids while pregnant can experience symptoms of opioid withdrawal in the days following birth, such as tremors, irritability, seizures, sleep, digestive, and feeding problems. However, little is known about the effect of antenatal opioid exposure on longer-term infant development over time. To address this gap in understanding, the ACT NOW Longitudinal study is examining a crucial developmental period from birth to two years of life through a comprehensive battery of assessments, including MRI imaging, neurodevelopmental behavioral assessments, and family report measures. This longitudinal cohort study is projected to include a total of 375 infants, 250 who were exposed to opioids and 125 matched controls.

The current overdose epidemic is being fueled by widespread, non-medical use of opioids prescribed by mostly well-meaning physicians who often lack adequate training on how to properly initiate, monitor, and discontinue opioid therapy. It is very difficult for physicians to fully assess a new patient?s risk of substance misuse and possible future overdose in the limited amount of time of a typical evaluation. The Care Continuity Program (CCP) is a novel, online patient self-assessment used by prescribers of opioids to better identify patient risk factors and therapy benefit. The CCP tool is completed by the patient, outside of the office, using an internet enabled device and follows a compliance-driven protocol. The results are instantly transmitted to the prescriber?s electronic health records (EHR), mitigating the prescriber?s civil and criminal liabilities. The study aims to validate the protocol and delivery system of the CCP by measuring patient outcomes, prescriber confidence, and completeness of documentation in the patient chart in primary care and pain management settings. If successful, this project can significantly expand the benefits of CCP to even a broader network of providers and help mitigate the impact of the opioid crisis

This study will evaluate the implementation of the Zero Suicide framework across six health systems serving over nine million people in collaboration with the Mental Health Research Network. The project will incorporate the voice of the patient and provider stakeholders as part of the implementation of the Zero Suicide framework in three health settings from the NIMH-funded parent award as well as the Southcentral Foundation which is an Alaska Native-owned, nonprofit health care organization serving nearly 65,000 American Indian/Alaskan Native people living in and around Anchorage, Alaska. The team will first systematically engage patients, providers, national consumer advocacy groups, and MHRN scientists in formulating research questions to address the prevention of opioid-related overdoses in people with Opioid Use Disorders (OUD) or people without diagnosed OUD who are using opioids for pain management. Next, the team will utilize semi-structured interviews to determine how people with OUD or people without diagnosed OUD who are using opioids for pain management are experiencing the implementation of the Zero Suicide framework in four diverse health systems. Experiences will be recorded using 80 semi-structured phone interviews in a diverse sample of patients who have survived an opioid-related overdose (50% intentional; 50% unintentional), as well as 20 Addiction Medicine, Primary Care, and/or Specialty Pain Medicine providers.

High rates of relapse and overdose deaths pose significant challenges to the treatment of Opioid Use Disorder (OUD). Anti-opioid immunotherapies (i.e., vaccines and monoclonal antibodies) have great potential to reduce long-term opioid use and overdose, with minimal risk of side effects, when used in conjunction with pharmacological treatments and/or behavioral therapies. The ability of an anti-opioid vaccine to induce antibodies that render an opioid less effective, or less rewarding, and protect from accidental overdose could provide an important therapeutic option for patients undergoing treatment for OUD. The goal of this collaborative study is to design, develop, and evaluate vaccines for use in the treatment of opioid use disorder
