Funded Projects

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. The majority of participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first decade of life. The University of Vermont study site will recruit mother-infant dyads from a rural area in Vermont, a state in which nearly one-third of neonatal hospitalizations are for neonatal abstinence syndrome (NAS).

Naloxone is a safe and effective opioid antagonist, but currently available products are burdened with high cost and limited accessibility due to a need for a prescription or being kept behind-the-counter. In response to the FDA putting out an unprecedented call for an over the counter naloxone product, Pocket Naloxone Corp. is developing a novel intranasal delivery method for naloxone intended to be low-priced and widely accessible. This project will culminate in a New Drug Application to the FDA for over-the-counter approval to meet the urgent need for widespread access to a reliable, easy-to-use naloxone product for use in an emergency by non-medical individuals.

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.

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 University of San Diego study site will recruit a diverse cohort of mother-infant pairs, including Hispanic and American Indian individuals.

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.

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.

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.

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 Arkansas Children’s Research Institute site is in a predominantly rural state with the second highest rate of opioid prescriptions in the U.S.

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.

Over-the-counter medicines such as non-steroidal anti-inflammatory drugs are ineffective for treating severe chronic pain and may have serious side effects from continued use, which limits treatment options. A kinase (an enzyme whose activity targets a specific molecule) called TAK1 is involved in the chronic pain process. This research will develop a molecule previously shown to be effective in a model of inflammatory pain that also inhibits TAK1. A main goal will be to determine if this inhibitor (takinib analog HS-276) can cross the blood-brain barrier and, if successful, pursue FDA  Investigative New Drug-enabling safety studies leading to a Phase I clinical trial and a potential new chronic pain treatment.

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 HEALthy Brain and Child Development National Consortium (HBCD-NC) Administrative Core (HCAC) will coordinate efforts across all sites in the HBCD-NC consortium to ensure that the consortium meets its primary objective to establish a normative model of developmental trajectories over the first 10 years of life. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. The HCAC will oversee study design and monitor the progress of each site’s ability to carry out a common research protocol and will assemble and distribute a comprehensive research dataset to the scientific community. This administrative core is located at the University of California, San Diego.
