The goal of the Tailored Retention and Engagement for Equitable Treatment of Opioid use disorder (OUD) and Pain (TREETOP) research program is to develop effective, equitable, and sustainable interventions for chronic pain and opioid misuse/disorder that improve engagement in medication for opioid misuse/disorder treatment and retention in office-based addiction treatment. TREETOP will prioritize disproportionately affected rural and Black communities. The Engagement research project will investigate whether pain self-management can improve pain and engage primary care patients to seek medication treatment for opioid misuse/disorder. The Retention project will investigate whether pain self-management and/or flexibly dosed buprenorphine/naloxone can improve pain and retention in treatment among patients who have already begun care in office-based addiction treatment programs. With engagement from stakeholders and representatives with varied perspectives and lived experiences, this research will advance the science of sustainably and equitably managing chronic pain and opioid misuse/disorder, prioritizing disproportionately affected communities.

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.

The objective of the HEALthy Brain and Child Development (HBCD) Prenatal Experiences and Longitudinal Development (PRELUDE) 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 Cincinnati Children’s Hospital study site is in a region hit hard by the opioid crisis and has a large catchment area that includes many rural counties in Ohio, Kentucky, Indiana, and West Virginia.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative template 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 and well curated research dataset to the scientific community at large. 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 University of New Mexico Health Science Center study site is in a largely rural/mixed state with one of the highest rates of overdose in the nation. This site will enroll diverse mother-infant pairs and partners or caregivers, including Hispanic/Latinx and American Indian individuals.

The Northwestern University study site is in Chicago where rates of prenatal substance use are rising and consistent with the national trend. This site will recruit a diverse urban sample of mother-infant pairs reflecting the population of Chicago.

Substance use disorder (SUD) is a serious public health and socioeconomic burden. In this project, researchers will develop novel drug compounds that dually target orexin receptors and kappa opioid receptors, which have both been implicated in SUD. The compounds will then be tested for effectiveness in preclinical models of SUD, including models of cocaine, methamphetamine, and fentanyl use. This research has the potential to provide highly impactful and innovative treatment options for SUD via simultaneous modulation of multiple signaling pathways.

There are currently no effective non-opioid-based pharmacotherapies for treatment of opioid use disorder (OUD). Glial cell line-derived neurotrophic factor (GDNF) is a beneficial protein normally present in low levels in the adult brain, and there is strong evidence that it has clinical potential as a therapy for OUD and relapse reduction. Researchers have developed a non-invasive approach that bypasses the blood-brain barrier to increase levels of GDNF using intranasal administration of gene nanoparticles that make GDNF protein within the brain. This project will test whether this intranasal GDNF gene therapy can suppress drug craving and reduce the tendency to start using a drug again after a period of abstinence in experimental models, thus providing a long-term therapeutic strategy for reducing opioid craving and preventing relapse.

In collaboration with Eolas Therapeutics and the NIH Blueprint Neurotherapeutics Network, AstraZeneca has developed a novel compound for treatment of opioid use disorder, AZD4041, which targets orexin 1 (OX1) receptors in the brain. In animal studies, AZD4041 reduced the motivation to consume opioids or nicotine, reduced relapse-like drug-seeking behaviors, and showed a favorable safety profile. The compound also has proven to be safe in an initial Phase 1 clinical trial in healthy human volunteers. This project will further evaluate the safety (e.g., respiratory depression profile) of AZD4041 in human volunteers, using multiple and increasing doses. Upon successful completion of these studies, the compound will be tested in a proof-of-concept efficacy study in patients with opioid use disorder. If this is successful, the compound will advance to larger Phase 2 and Phase 3 pivotal clinical trial to tests its effectiveness in the treatment of opioid use disorder.

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 HEALthy Brain and Child Development National Consortium (HBCD-NC) Data Coordinating Center (HDCC) will provide data management and oversight to all HBCD-NC sites to ensure the consortium’s primary objective of establishing a normative template of developmental trajectories over the first 10 years of life is met. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. The HDCC will coordinate data collection, data quality, data harmonization, data sharing, and data analysis efforts that are central to the consortium’s ability to implement a common research protocol. The HDCC will assemble all data across the consortium sites and distribute a comprehensive and well curated research dataset to the scientific community at large. The HDCC is tightly integrated with the HEALthy Brain and Child Development Administrative Core (HCAC) and includes a multi-institution investigative team at the University of Minnesota, University of California, San Diego, and Washington University at St Louis.
