Development of Specific Mu Opioid Receptor Antagonists to Reverse the Acute and Chronic Toxicity of Fentanyls Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA Virginia Commonwealth University ZHANG, YAN Richmond, Virginia 2022
NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: PAR-20-092
Summary:

Fentanyl and its analogs are synthetic opioids that are 100 to 10,000 times more potent than morphine. Overdose from these opioids is extremely dangerous due to their ultra-potency and longer half-life than naloxone, the front-line treatment for fentanyl overdose. This research study will develop novel mu opioid receptor antagonists that bind to the same receptor as the opioid drugs and specifically counteract fentanyl and its analogs, thereby reversing the drugs’ acute toxicity more effectively and with fewer side effects than current treatments. The researchers will characterize novel fentanyl derivatives, identify promising compounds, and pursue preclinical development of these compounds as novel reversal agents against the acute toxicity of fentanyl. The goal is to file an Investigational New Drug application with the U.S. Food and Drug Administration.

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.

Characterization, Optimization, and Development of Dual mGlu2/3 Positive Allosteric Modulators for Opioid Use Disorder 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 COSFORD, NICHOLAS DAVID; VELICELEBI, GONUL La Jolla, CA 2022
NOFO Title: Strategic Alliances for Medications Development to Treat Substance Use Disorders (R01Clinical Trial Optional)
NOFO Number: PAR-19-318
Summary:

Given recent increases in co-use of opioids and methamphetamine, there is a dire need for novel treatment strategies that prevent relapse to drug use in both opioid use disorder (OUD) and methamphetamine use disorder (MUD). The localization of certain receptors for the neurotransmitter glutamate—metabotropic glutamate receptor subtypes 2 and 3 (mGlu2/3)—and the mechanism through which they transmit signals, strongly suggest that activation of both of these receptors will effectively treat multiple symptoms that contribute to relapse, such as responsiveness to drug cues, physical withdrawal symptoms, neuroinflammation, and sleep disturbances. This project seeks to evaluate molecules that can activate mGlu2/3 receptors without binding to the same site as glutamate (i.e., positive allosteric modulators) as a novel pharmacological treatment for preventing relapse to OUD. The research also will examine the potential of such modulators for treating MUD.

Recruiting Active Expiration to Overcome Opioid-Induced Persistent Apnea Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA University of California, Los Angeles FELDMAN, JACK L Los Angeles, CA 2022
NOFO Title: HEAL Initiative: Novel Targets for Opioid Use Disorders and Opioid Overdose (R21 Clinical Trial Not Allowed)
NOFO Number: RFA-DA-22-032
Summary:

Prescription opioids provide pain relief, but overdose can be fatal because opioids also depress breathing through opioid-induced persistent apnea, when breathing stops. This research will determine whether targeted activation of a specific, opioid-insensitive brain region that triggers exhalation can increase tolerance to fentanyl-induced apnea. The research also seeks to identify the receptors responsible for this exhalation, which could be targets for new medications that prevent the negative impact of opioids on breathing. This research lays the groundwork for more preclinical and translational studies to prevent opioid-induced persistent apnea.

Targeting Tiam1-Mediated Synaptic Plasticity for the Relief of Opioid Tolerance Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA Baylor College of Medicine LI, LINGYONG (contact); TOLIAS, KIMBERLY Houston, TX 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:

Chronic opioid use results in tolerance, a primary driver for opioid misuse and overdose that directly contribute to increased morbidity and mortality. Changes in neuronal connectivity known as synaptic plasticity are a key determinant of opioid tolerance, but the underlying molecular mechanisms remain unclear. Tiam1 is a protein known to control the development of nerve cells and their connections and is also involved in morphine-induced neuronal changes. This research will examine Tiam1-mediated synaptic plasticity underlying opioid tolerance and validate Tiam1 as a potential therapeutic target for prevention of tolerance development.
