Synthesis of peripherally active CB1 agonists as analgesics Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS ST. LOUIS COLLEGE OF PHARMACY MAJUMDAR, SUSRUTA (contact); DROR, RON ; GEREAU, ROBERT W St. Louis, MO 2021
NOFO Title: HEAL Initiative: Planning Studies for Initial Analgesic Development Initial Translational Efforts [Small Molecules and Biologics] (R34 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-21-016
Summary:

Current medications for chronic pain are largely ineffective and rely heavily on opioids, one contributor to the nation’s opioid crisis. The endocannabinoid system that consists of cannabinoid receptors (CB1R and CB2R) and their endogenous ligands is a natural pathway in the human body and has emerged as an alternative target for developing new pain medications with few side effects. Current molecules that bind to CB1R in the brain and spinal cord have psychoactive side effects, limiting their therapeutic use for treating chronic pain. This study aims to develop new molecules to bind to CB1R tightly and selectively, are metabolically stable, and are also unable to enter the brain.

Regulation of Trigeminal Nociception by TRESK Channels Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS WASHINGTON UNIVERSITY CAO, YUQI St. Louis, MO 2018
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

TWIK-related spinal cord K+ (TRESK) channel is abundantly expressed in all primary afferent neurons (PANs) in trigeminal ganglion (TG) and dorsal root ganglion (DRG), mediating background K+ currents and controlling the excitability of PANs. TRESK mutations cause migraine headache but not body pain in humans, suggesting that TG neurons are more vulnerable to TRESK dysfunctions. TRESK knock out (KO) mice exhibit more robust behavioral responses than wild-type controls in mouse models of trigeminal pain, especially headache. We will investigate the mechanisms through which TRESK dysfunction differentially affects TG and DRG neurons. Based on our preliminary finding that changes of endogenous TRESK activity correlate with changes of the excitability of TG neurons during estrous cycles in female mice, we will examine whether estrogen increases migraine susceptibility in women through inhibition of TRESK activity in TG neurons. We will test the hypothesis that frequent migraine attacks reduce TG TRESK currents.

1/2 Optimizing access, engagement and assessment to elucidate prenatal influences on neurodevelopment: The Brains Begin Before Birth (B4) Midwest Consortium Enhanced Outcomes for Infants and Children Exposed to Opioids HEALthy Brain and Child Development Study (HBCD) NIDA WASHINGTON UNIVERSITY ROGERS, CYNTHIA ELISE (contact); SMYSER, CHRISTOPHER DANIEL St. Louis, MO 2019
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:

Though prenatal exposure to opioids and other substances have adverse effects on neurodevelopment, advances in neuroimaging and developmentally sensitive phenotypic measurement now enable characterization of typical and atypical brain-behavior pathways on an unprecedented scale. The Brains Begin Before Birth (B4) Midwest Consortium, a partnership of neuroscience, substance use, perinatal mental health, and child welfare scientists at Washington University School of Medicine (WUSM) and neuroscience, bioethics, pediatric population health, maternal-fetal, and addiction scientists at Northwestern University (NU). This regional consortium will leverage the contrasting approaches of Illinois (punitive) and Missouri (non-punitive) to prenatal opioid use, providing a platform for examining the impact of jurisdictional variations on science and practice. The consortium provide a framework for addressing three major areas of challenge: (1) legal/ethical, (2) recruitment/retention, and (3) imaging/assessment methods.

Development of an implantable closed-loop system for delivery of naloxone for the prevention of opioid-related overdose deaths Novel Therapeutic Options for Opioid Use Disorder and Overdose Focusing Medication Development to Prevent and Treat Opioid Use Disorder and Overdose NIDA Washington University Rogers, John St. Louis, MO 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:

Current opioid overdose treatment requires administration of naloxone by first responders, which requires timely identification of the overdose, the need for a rescue injection, and immediate availability of the medication. The development of a fail-safe treatment that would provide a life-saving dose of naloxone without the need for intervention by another party could significantly reduce mortality. The researchers aim to develop a new medical device comprising an implantable, closed-loop system that senses the presence of an opioid overdose, automatically administers a life-saving bolus injection of naloxone, and simultaneously alerts first responders.

Discovery and validation of a novel orphan GPCR as a target for therapeutic intervention in neuropathic pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS St. Louis University SALVEMINI, DANIELA St. Louis, MO 2019
NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

Neuropathic pain conditions are exceedingly difficult to treat, and novel non-opioid analgesics are desperately needed. Receptomic and unbiased transcriptomic approaches recently identified the orphan G-protein coupled receptor (oGPCR), GPR160, as a major oGPCR whose transcript is significantly increased in the dorsal horn of the spinal cord (DH-SC) ipsilateral to nerve injury, in a model of traumatic nerve-injury induced neuropathic pain caused by constriction of the sciatic nerve in rats (CCI). De-orphanization of GPR160 led to the identification of cocaine- and amphetamine-regulated transcript peptide (CARTp) as a ligand which activates pathways crucial to persistent pain sensitization. This project will test the hypothesis that CARTp/GPR160 signaling in the spinal cord is essential for the development and maintenance of neuropathic pain states. It will also validate GPR160 as a non-opioid receptor target for therapeutic intervention in neuropathic pain, and characterize GPR160 coupling and downstream molecular signaling pathways underlying chronic neuropathic pain.

SPRINT: Signature for Pain Recovery IN Teens Preclinical and Translational Research in Pain Management Discovery and Validation of Biomarkers, Endpoints, and Signatures for Pain Conditions NINDS STANFORD UNIVERSITY SIMONS, LAURA E Stanford, CA 2019
NOFO Title: Discovery of Biomarkers, Biomarker Signatures, and Endpoints for Pain (R61/R33 Clinical Trial Optional)
NOFO Number: RFA-NS-18-041
Summary:

Up to 5 percent of adolescents suffer from high-impact chronic musculoskeletal (MSK) pain, and only about 50 percent with chronic MSK pain who present for treatment recover. Current treatments for chronic MSK pain are suboptimal and have been tied to the opioid crisis. Discovery of robust markers of the recovery versus persistence of pain and disability is essential to develop more resourceful and patient-specific treatment strategies, requiring measurements across multiple dimensions in the same patient cohort in combination with a suitable computational analysis pipeline. Preliminary data has implicated novel candidates for neuroimaging, immune, quantitative sensory, and psychological markers for discovery. In addition, a standardized specimen collection, processing, storage, and distribution system is in place, along with expertise in machine learning approaches to extract reliable and prognostic bio-signatures from a large and complex data set. This project will facilitate risk stratification and a resourceful selection of patients who are likely to respond to current multidisciplinary pain treatment approaches.

Integrating Tailored Postoperative Opioid Tapering and Pain Management Support for Patients on Long-Term Opioid Use Presenting for Spine Surgery (MIRHIQL) Clinical Research in Pain Management Reducing Opioid-Related Harms to Treat Chronic Pain (IMPOWR and MIRHIQL) NIDA STANFORD UNIVERSITY HAH, JENNIFER Stanford, CA 2023
NOFO Title: HEAL Initiative: Multilevel Interventions to Reduce Harm and Improve Quality of Life for Patients on Long Term Opioid Therapy (MIRHIQL) (R01 Clinical Trial Required)
NOFO Number: RFA-DA-23-041
Summary:

Decreasing opioid dosing faster than advised by clinical recommendations often leaves chronic pain unaddressed and may increase the risk of overdose and suicide compared to continuing long-term opioid treatment. Continued, long-term use of opioids after surgery by individuals who use opioids increases the risk of postoperative complications, opioid use disorder, and death. Surgery is a critical point-of-care moment for health care providers to interact with patients who use opioids about continued opioid use when harms outweigh benefits. This project will test of the Motivational Interviewing and guided Opioid Tapering support (MI-Opioid Taper) strategy, with or without a medication that reduces anxiety and relieves pain, at four geographically diverse hospitals across the nation.

Novel Models to Study Dorsal Root Ganglion Neurons in Knee Osteoarthritis Pain Cross-Cutting Research Training the Next Generation of Researchers in HEAL NIAMS STANFORD UNIVERSITY BREWER, CHELSIE L Stanford, CA 2023
NOFO Title: HEAL Initiative Advanced Postdoctoral-to-Independent Career Transition Award in PAIN and SUD Research (K99/R00 Independent Clinical Trial Not Allowed)
NOFO Number: RFA-NS-22-022
Summary:

Knee osteoarthritis (OA) is a frequent cause of disability and chronic pain. Treatment often relies on analgesics like opioids to manage OA pain, with all the associated risks; other approaches to treat OA are often invasive and inaccessible to patients. Therefore, novel analgesic strategies are needed to reduce the high burden of knee OA-induced pain. This project aims to study in detail and target the sensory neurons that drive OA pain to assist in the development of more effective pain therapeutics.

Clinical Translation of Ultrasonic Ketamine Uncaging for Non-Opioid Therapy of Chronic Pain Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NINDS STANFORD UNIVERSITY AIRAN, RAAG D (contact); WILLIAMS, NOLAN R Stanford, CA 2019
NOFO Title: HEAL Initiative: Translational Devices to Treat Pain (UG3/UH3 Clinical Trial Optional)
NOFO Number: RFA-NS-19-016
Summary:

The research team has developed ultrasonic drug uncaging for neuroscience, in which neuromodulatory agents are uncaged from ultrasound-sensitive biocompatible and biodegradable drug-loaded nanocarriers. This project will clinically translate ultrasonic ketamine uncaging for chronic pain therapy. In the UG3 phase, the research team will scale our nanoparticle production processes to human scales and adapt them to pharmaceutical standards. In the UH3 phase, they will complete a first-in-human evaluation of the safety and efficacy of ultrasonic ketamine uncaging by quantifying how much ketamine is released relative to the ultrasound dose and assessing whether the uncaged ketamine can modulate the sensitivity and affective response to pain, in patients suffering from chronic osteoarthritic pain. This project aims to yield a novel, noninvasive, non-opioid therapy for chronic pain that maximizes the therapeutic efficacy of ketamine over its side effects, by targeting its action to a critical hub of pain processing.

Arousal circuitry and opiate-associated memories New Strategies to Prevent and Treat Opioid Addiction Sleep Dysfunction as a Core Feature of Opioid Use Disorder and Recovery NHLBI Stanford University DE LECEA, LUIS (contact); CHEN, XIAOKE Stanford, CA 2019
NOFO Title: HEAL Initiative: Sleep and Circadian-Dependent Mechanisms Contributing to Opiate Use Disorder (OUD) and Response to Medication Assisted Treatment (MAT) (R01 - Clinical Trial Not Allowed)
NOFO Number: RFA-HL-19-028
Summary:

Repetitive drug use forms powerful memories associating drug-evoked experiences with its proximal environmental cues. Memories are major obstacles for successfully treating addiction, since even after a prolonged period of abstinence, reexposure to such cues often triggers craving that promotes relapse. A polysynaptic pathway from the paraventricular nucleus of the thalamus (PVT) to the lateral hypothalamus (LH) has been shown to play a role in the maintenance of the opioid-associated memories. Hypocretin (Hcrt) neurons in the LH strongly innervate the PVT, required for maintaining wakefulness and involved in drug seeking. These factors may link sleep disorders in opioid addicts with their long-lasting drug-associated memories. This study will (1) determine whether Hcrt neurons in the LH are the major target; (2) examine whether manipulating the LH (Hcrt)-PVT pathway can effectively prevent relapse; and (3) test whether sleep intervention could be an effective strategy to prevent relapse.

Mechanisms of Action of Peripheral Nerve Stimulation for the Treatment of Chronic Neuropathic Pain Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NINDS STANFORD UNIVERSITY HAH, JENNIFER (contact); BISWAL, SANDIP; CHADWICK, ANDREA LYNN Stanford, CA 2023
NOFO Title: HEAL Initiative: Interdisciplinary Team Science to Uncover the Mechanisms of Pain Relief by Medical Devices (RM1 Clinical Trial Optional)
NOFO Number: RFA-NS-23-003
Summary:

Technology approaches that deliver electrical current through the skin near a damaged or injured peripheral nerve are used to treat chronic neuropathic pain that does not respond to other treatments. This project will optimize this nerve stimulation approach while also determining how the stimulation works to reduce pain in the body. The research will also look for patient characteristics that predict response by conducting a clinical trial comparing combined peripheral nerve stimulation and conventional medical treatment to medication alone.

Using Virtual Reality Psychological Therapy to Develop a Non-Opioid Chronic Pain Therapy Cross-Cutting Research Small Business Programs NINR COGNIFISENSE, INC. BAEUERLE, TASSILO; CEKO, MARTA ; WEBSTER, LYNN Sunnyvale, CA 2019
NOFO Title: PHS 2017-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44])
NOFO Number: PA-17-302
Summary:

Chronic pain affects over 100 million Americans, costing society about $600 billion annually. Despite numerous pharmacological and non-pharmacological therapies, over 50% of chronic pain sufferers feel little control over their pain. CognifiSense has developed a patent-pending Virtual Reality Psychological Therapy (VRPT), which is designed to create lasting reduction of chronic pain by addressing the maladaptive learning processes driving pain chronification. VRPT is an experiential learning system, which provides the brain a new set of signals that teaches it that the pain is not as bad as it perceived and that it has greater control over the pain than it perceived. VRPT combines the immersive power and the ability to individualize the therapy of Virtual Reality with well-researched principles of self-distancing, self-efficacy, and extinction to retrain the brain. The goal of this study is to determine the clinical feasibility of VRPT in achieving a lasting reduction of chronic pain, establish brain mechanisms associated with treatment response, and collect comprehensive user feedback to enable further refinement of the current product prototype. CognifiSense's VRPT has the potential to be a significant clinical and business opportunity in the treatment of chronic pain.

Closed-Loop Micromagnetic Neuromodulation as a Non-Opioid Treatment for Neuropathic Pain Cross-Cutting Research Small Business Programs NINDS QUANTUM NANOSTIM REILLY, THOMAS Treasure Island, FL 2021
NOFO Title: HEAL Initiative: Development of Therapies and Technologies Directed at Enhanced Pain Management (R43/R44 – Clinical Trial Not Allowed)
NOFO Number: RFA-NS-20-011
Summary:

Spinal cord stimulation (SCS) has been shown to provide effective relief for most people with chronic pain and eliminated the need for opioid therapy in more than half of those treated. However, traditional SCS approaches have encountered problems when glial cells coat the stimulation electrodes that distance the device from targeted neurons. This project will develop a novel hybrid Closed Loop Omnidirectional Neuromodulation with Electromagnetic fields (CLONE) system that is combined with magnetic-based stimulation to overcome glial coating of SCS electrodes, better target neurons in dorsal spine tissue, which may lead to better treatment of chronic neuropathic neck and low back pain.

Antagonists of CRMP2 Phosphorylation for Chemotherapy-Induced Peripheral Neuropathy Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS UNIVERSITY OF ARIZONA KHANNA, RAJESH Tucson, Arizona 2022
NOFO Title: HEAL Initiative: Planning Studies for Initial Analgesic Development [Small Molecules and Biologics] (R61 Clinical Trial Not Allowed)
NOFO Number: NS21-029
Summary:

A more thorough understanding of neuropathic pain is critical for developing new target-specific medications. Researchers know that peripheral nerve injury changes various cell processes that affect two ion channels linked with chronic pain. Preliminary studies indicate that molecular changes known as phosphorylation to the collapsin response mediator protein 2 (CRMP2), one of five intracellular phosphoproteins, promotes abnormal excitability in the brain region that contributes to neuropathic pain. This project aims to develop small molecule inhibitors of CRMP2 phosphorylation as potential therapeutics for pain.

Optimization of Betulinic Acid analogs for T-type calcium channel inhibition for non-addictive relief of chronic pain Cross-Cutting Research Small Business Programs NIDA REGULONIX, LLC KHANNA Tucson, AZ 2019
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:

The increase in prevalence of cancer coupled with an increase in the cancer survival rates due to chemotherapy regimens is transforming cancer pain into a large, unmet medical problem. Chemotherapy-induced peripheral neuropathy (CIPN) is a common and potentially dose-limiting side effect of many cancer drug treatment regimens and is caused in part by alterations in ion channels; blocking or depleting Cav3.2 channels in dorsal root ganglion (DRG) neurons should thus mediate analgesic effects. This proposal aims to develop and test potent, orally available, and selective Cav3.2 channel antagonists, building on the structure of a medicinal plant product—betulinic acid (BA)—that has been identified to be Cav3.2-selective and antinociceptive in CIPN. Such compounds could reduce the reliance on opioids in cancer patients.

Discovery of T-type Calcium Channel Antagonists from Multicomponent Reactions and Their Application in Paclitaxel-induced Peripheral Neuropathy Cross-Cutting Research Small Business Programs NINDS REGULONIX, LLC KHANNA, RAJESH Tucson, AZ 2019
NOFO Title: PHS 2017-02 Omnibus Solicitation of the NIH for Small Business Technology Transfer Grant Applications (Parent STTR [R41/R42])
NOFO Number: PA-17-303
Summary:

Chemotherapy-induced peripheral neuropathy (CIPN) is detected in 64% of cancer patients during all phases of cancer. CIPN can result in chemotherapy dose reduction or discontinuation, and can also have long-term effects on the quality of life. Taxanes (like Paclitaxel) may cause structural damage to peripheral nerves, resulting in aberrant somatosensory processing in the peripheral and/or central nervous system. Dorsal root ganglia (DRG) sensory neurons as well as neuronal cells in the spinal cord are key sites in which chemotherapy induced neurotoxicity occurs. T-type Ca2+ channels are critical determinants of increased neuronal excitability and neurotransmission accompanying persistent neuropathic pain. Though Cav3.2 has been targeted clinically with small molecule antagonists, no drugs targeting these channels have advanced to phase II human clinical trials. This proposal aims to explore multicomponent reaction products, for the rapid identification of potent and selective T-type Ca2+ channel antagonists. The work proposed here is the first step in developing non-opioid pain treatments for CIPN. The team anticipates success against paclitaxel-induced chronic pain will translate into other chronic pain types as well, but CIPN provides focus for early stage proof-of-concept.
