Development and Validation of a Novel Point-of-Care Technology for Rapid Non-Targeted Identification of Emerging Opioid and Other Drug Threats Novel Therapeutic Options for Opioid Use Disorder and Overdose Rapidly Assessing the Public Health Impact of Emerging Opioid Threats NIDA UNIVERSITY OF CALIFORNIA, SAN DIEGO WERB, DANIEL M (contact); HALL, DREW ALEXANDER La Jolla, CA 2023
NOFO Title: HEAL Initiative: Rapidly Assessing the Public Health Impact of Emerging Opioid Threats (UG1 - Clinical Trial Not Allowed)
NOFO Number: RFA-DA-23-045
Summary:

Drug checking services provide individuals who use drugs with information about the true contents of their purchases, and thus may help prevent overdoses. However, current technologies are either costly, technically complex, and non-portable or subject to false signals and restricted in their detection capabilities. This project will continue development of a new, simple-to-use, point-of-care analytical technology (DoseCheck) that can rapidly detect established drug threats in a sample and recognize newly emerging drugs. The project will also attempt to adapt DoseCheck to provide rapid results in emergency overdose situations and improve the analytical capabilities of medical examiners in under-resourced jurisdictions.

The HEALthy Brain and Child Development National Consortium Administrative Core Enhanced Outcomes for Infants and Children Exposed to Opioids HEALthy Brain and Child Development Study (HBCD) NIDA UNIVERSITY OF CALIFORNIA, SAN DIEGO CHAMBERS, CHRISTINA (contact); NELSON, CHARLES ALEXANDER La Jolla, CA 2023
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.

Transcriptomic Single-Cell Profiling in Breathing-Specific Parabrachial Mu-Opioid Receptor Neurons Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA Salk Institute for Biological Sciences HAN, SUNG La Jolla, CA 2022
NOFO Title: HEAL Initiative: Novel Targets for Opioid Use Disorders and Opioid Overdose (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-DA-22-031
Summary:

Opioids can be effective analgesics but can also be fatal due to opioid-induced respiratory depression after overdose. This project will use cutting-edge molecular, physiological, behavioral, and imaging techniques to better understand and distinguish opioid-induced respiratory depression and opioid-mediated analgesia. Nerve cell-specific, single-cell transcriptomic analysis will be used to identify functional markers expressed in nerve cells that play a specific role in opioid-induced respiratory depression, but not opioid analgesia. This research study will help to identify novel therapeutic targets that could selectively rescue opioid-induced respiratory depression while maintaining the beneficial pain-relieving effects of opioids.

Brain-Penetrant GPR88 Agonists as Novel Therapeutics for Opioid Abuse Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA Sanford Burnham Prebys Medical Discovery Institute SMITH, LAYTON HARRIS; KENNY, PAUL J La Jolla, CA 2022
NOFO Title: HEAL Initiative: Novel Targets for Opioid Use Disorders and Opioid Overdose (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-DA-22-031
Summary:

Opioid dependence is a leading cause of premature illness and death. Previous research suggests that a protein called G-protein coupled receptor (GPR88) controls many addiction-relevant behavioral and physiological actions of opioids. This research study will validate GPR88 as a drug target for opioid use disorder as well as develop novel, brain-penetrant GPR88-binding molecules with properties optimized for treating opioid dependence. This research is an initial step toward the goal of developing GPR88-binding molecules as novel therapeutics to facilitate abstinence in people dependent on opioids.

Development of SBI-553, an allosteric modulator of NTR1, for the treatment of substance use disorders Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA Sanford Burnham Prebys Medical Discovery Institute Pinkerton, Anthony La Jolla, CA 2019
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:

Addiction to opioids is related to the physiology of the brain’s dopamine-based reward system. As a modulator of dopaminergic systems, the neurotensin 1 receptor (NTR1) should be a molecular target for treating addictive disorders; however, few non-peptide brain penetrant neurotensin modulators have been identified, and orthosteric NTR1 ligands display side effects that have limited their clinical development. This group discovered a series of brain-penetrant NTR1 modulators, including a lead compound SBI-553, with a unique mechanism of action at NTR1. SBI-553 is an orally available, brain penetrant ?-arrestin biased allosteric modulator of NTR1, which shows efficacy in a range of addiction models and circumvents the clinically limiting side effects. While potentially high risk, the activity of SBI-553 has been validated in vitro and in vivo, and the initial safety profiling indicates no issues that would preclude further development. This study will develop SBI-553 as a treatment for opioid use disorder.
