NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: RFA-DA-19-002
Summary:

Chronic pain affects an estimated 100 million Americans, or one third of the U.S. population, and it is the primary reason Americans are on disability. Although many treatments are available for pain, the most potent class of analgesics relies on opioid analogs, whose limitations and well-known adverse effects have contributed to the present opioid crisis. New pharmacotherapies for pain management are sorely needed. MTX1604, a synthetic endomorphin analog, has emerged as a highly effective analgesic that exhibits reduced reward potential and respiratory suppression, and a robust duration of efficacy in a variety of validated animal models of acute, neuropathic, inflammatory, post-operative, and visceral pain. This project will generate additional preclinical characterization data of MTX1604 and advance clinical development toward FDA approval. If successful, this medication development project could offer patients a novel non-addictive, potent, and safe analgesic and thus have a direct impact on the opioid crisis.

NOFO Title: Notice of Special Interest (NOSI): HEAL Initiative: Biospecimen Collection in Pregnancy
NOFO Number: NOT-DA-23-005
Summary:

Opioid use during pregnancy is associated with adverse outcomes for pregnant individuals and offspring. The mechanisms through which these outcomes arise and the consequences of prenatal opioid exposure on child health and development remain largely unexplored. The HEALthy Brain and Child Development (HBCD) Study is a nationwide longitudinal prospective study of early child development that will assess a broad spectrum of biological, behavioral, social, and health factors among 7,500 pregnant women and their children from pregnancy to mid-childhood. This supplement will expand the biospecimen collection of the HBCD protocol at the University of North Carolina at Chapel Hill to include delivery specimens (placenta, cord tissue, and cord blood). This will provide an unprecedented resource-generating opportunity for the larger scientific community to comprehensively evaluate mechanisms that mediate the connection between substance use during pregnancy and adverse neonatal, infant, and/or maternal health outcomes and inform innovative preventive strategies.

NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

Current rates of prescription opioid misuse are rising to epidemic levels among adults. These rates may be even higher among adolescents and young adults (AYAs), who have elevated levels of substance exploration and misuse during this precise developmental period. AYAs who are exposed to opioids via legitimate prescriptions by age 18 are at increased risk for misuse after high school. However, there is a substantial gap in our knowledge of what factors might contribute to the development of misuse and related poor outcomes in these high-risk youth. Identifying factors that convey risk for increasing opioid use and problematic use would inform AYA models of opioid abuse and inform the development of preventive interventions to modify risk in medical settings, which are a unique point of entry into opioid use, and a key setting in which to examine AYA outcomes. We will use a developmental model of the impact of opioid exposure by legitimate prescription during late adolescence, with consideration for pain and psychological characteristics of the individual within the psychosocial (family, peer, educational and work context). Determining mechanisms and moderators of risk during this developmental transition will provide critical information for the design of interventions aimed at reducing opioid use disorders in at-risk AYA.

NOFO Title: HEAL Initiative: America’s Startups and Small Businesses Build Technologies to Stop the Opioid Crisis (R43/R44 - Clinical Trial Optional)
NOFO Number: RFA-DA-19-019
Summary:

Current agonist treatments for opioid use disorder (OUD) are not adequate to address the opioid crisis and have abuse liability concerns. Chemokines (hormones of the immune system that mediate innate immune inflammation) enhance pain, reduce opioid analgesia, and promote drug-seeking behavior and addiction—giving them a central role at the crossroads of chronic pain and the opioid crisis. So blocking chemokines (rather than opioid receptors) provides an exciting and untested treatment opportunity for pain and OUD. This proposal will assess, in animal self-administration models that mimic human drug-taking, whether a chemokine antagonist peptide R103 reduces morphine intake, as well as if R103 will prevent or blunt naloxone-precipitated withdrawal signs in morphine-dependent rats and stop relapse.

NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: RFA-DA-19-002
Summary:

Over 2 million Americans have an Opioid Use Disorder (OUD) and the risks associated with misuse of opioids have prompted a public health crisis. There are three effective FDA-approved drugs for medication assisted treatment (MAT) of OUD. However, while MAT can reduce overall OUD related mortality by as much as fifty percent, relapse and treatment discontinuation are common within the first 5 to 12 weeks of MAT. As longer treatment retention is correlated with better long-term outcomes, the development of an adjunctive medication to alleviate key psychiatric symptoms associated with treatment failure would address an important unmet need. This study seeks to evaluate the safety and efficacy of brexpiprazole as adjunctive treatment to buprenorphine/naloxone in OUD. If successful, this study could enhance the effectiveness of OUD treatments by extending the duration of treatment, thereby reducing the likelihood for relapse and overdose.

NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

Neurostimulation techniques, such as transcranial direct current stimulation (tDCS), have been used as interventions for substance use disorders. This is a supplement to the currently NIDA-funded UG3 DA047793, “tDCS to Decrease Opioid Relapse,” which will measure behavioral and brain responses following tDCS stimulation delivered during tasks that use a particular brain network involved in cognitive control, and utilizing FMRI to assess the effects. This supplement allows the researchers to add an EEG measurement to the study, to get a complete picture of how tDCS might affect the function of key brain networks in ways that could be helpful for SUDs.

NOFO Title: Notice of Special Interest (NOSI): Availability of Administrative Supplements for Helping to End Addiction Long-term (HEAL) Initiative awardees to make data Findable, Accessible, Interoperable, and Reusable (FAIR) through the HEAL Data Ecosystem
NOFO Number: NOT-OD-22-110
Summary:

This research provides support to strengthen data management, data sharing, and data readiness efforts within the HEAL Initiative. This support further fosters collaboration among HEAL awardees and enables maximal data discoverability, interoperability, and reuse by aligning with the FAIR (Findable, Accessible, Interoperable, and Reusable) principles. It also provides an opportunity for existing HEAL Initiative award recipients to increase data “FAIR”-ness, participate in coordinated HEAL Initiative activities to build community around data sharing, and foster sustainability of HEAL Initiative digital assets.

NOFO Title: HEAL Initiative: Justice Community Opioid Innovation Network (JCOIN) Clinical Research Centers (UG1 Clinical Trial Optional)
NOFO Number: RFA-DA-19-025
Summary:

Individuals who have been previously incarcerated have a significantly higher risk of dying from opioid overdose, particularly in the first two weeks after release. Providing medication for opioid use disorder (MOUD) to individuals on probation or parole decreases the rate of relapse and recidivism, and increases retention in substance abuse treatment. This study will test a systems-change approach for increasing use of MOUD across a network of seven probation and parole sites to improve linkage to the continuum of evidence-based care for justice-involved individuals. Implementation outcomes include program acceptability, adoption, penetration, sustainability, and costs. Client-level effectiveness outcomes include retention, satisfaction, opioid use, opioid overdoses, recidivism, linkage to OUD treatment, and utilization of recovery services. Targeting the intersection of justice and community-based care has substantial potential for addressing the opioid crisis.

NOFO Title: HEAL Initiative: HEALthy Brain and Child Development Study (HEALthy BCD) (Collaborative R34 Clinical Trial Not Allowed)
NOFO Number: RFA-DA-19-029
Summary:

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.

NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

We propose to estimate the impact of expanded access to medication-assisted treatment (MAT) in prisons and jails on post-release rates of overdose. Our approach will use agent-based modeling, data collected through the parent study, existing surveillance data, and recently published data from similar settings to understand how different MAT interventions in the prison and jail setting impact overdose death post-release. We will examine the impact of standard of care/no intervention, providing access to depot-naltrexone alone, providing access to all three MATs to only those who were prescribed it prior to incarceration, and comprehensive provision of all three MATs on post-release rates of overdose. These models will incorporate advanced methodological techniques that will allow for the investigation of engaged treatment, program attrition, and other complex events on a population level. This study’s findings may be used by health agencies, policymakers, and correctional systems to inform their efforts to expand MAT access.

NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: RFA-DA-19-002
Summary:

Tens of thousands of people die each year from opioid overdose. Many of these people began taking opioids for pain. A critical treatment goal is to reduce the development of opioid dependence either by enhancing opioid analgesia so lower doses can be used or by blocking withdrawal symptoms. Current pharmacological treatments in these two categories, although effective, present serious limitations. The recent finding that reducing the signaling through mu-delta opioid heterodimers appears to enhance opioid antinociception and reduce dependence suggests that a blocker of mixed mu-delta receptors (MDOR antagonist) could be effective in reducing dependence by limiting opioid tolerance and preventing opioid withdrawal. This research group has developed a compound with that characteristic, called D24M, which preliminary studies have shown could reduce opioid dependence by enhancing opioid antinociception, reducing opioid tolerance, or directly inhibiting opioid withdrawal. They propose to extend this research by investigating whether it can reduce chronic pain in an animal model that mimics the clinical situation of pain patients who transition to dependence. If these studies are successful, they could lead to the development of an optimized drug ready for Investigational New Drug (IND) application and enable translational and clinical testing.
