Temporal Patterns of Spinal Cord Stimulation Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NIBIB DUKE UNIVERSITY GRILL, WARREN M Durham, NC 2019
NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

This project will design and test optimized temporal patterns of stimulation to improve the efficacy of commercially available spinal cord stimulation (SCS) systems to treat chronic neuropathic pain. Researchers will build upon a validated biophysical model of the effects of SCS on sensory signal processing in neurons within the dorsal horn of the spinal cord to better understand how to improve the electrical stimulus patterns applied to the spinal cord. They will use sensitivity analyses to determine the robustness of stimulation patterns to variations in electrode positioning, selectivity of stimulation, and biophysical properties of the dorsal horn neural network. Researchers will demonstrate improvements from these new stimulus patterns by 1) measuring their effects on pain-related behavioral outcomes in a rat model of chronic neuropathic pain and by 2) quantifying the effects of optimized temporal patterns on spinal cord neuron activity. The outcome will be mechanistically derived and validated stimulus patterns that are significantly more efficacious than the phenomenologically derived standard of care patterns; these patterns could be implemented with either a software update or minor hardware modifications to existing SCS products.

Development of a Wireless Endovascular Nerve Stimulator for Treatment of Refractory Neuropathic Pain Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NIBIB BAYLOR COLLEGE OF MEDICINE KAN, PETER TZE MAN; ROBINSON, JACOB T; SHETH, SUNIL Houston, TX 2019
NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

For patients with neuropathic pain refractory to therapy using small molecules, modulation of specific neural structures in the central or peripheral nervous system can provide effective alternative treatments. While current Food and Drug Administration–approved devices for dorsal root ganglion (DRG) stimulation are safe and effective, there have been an unfortunate number of adverse events associated with pulse generator infections and lead migration. The research team will develop a wireless, millimeter-sized nerve stimulator that can be delivered through the vasculature and stimulate the DRG to alleviate symptoms of neuropathic pain and the associated minimally invasive delivery method. This endovascular nerve stimulation (EVNS) system depends on development and integration of key novel technologies into an endovascular stent. The magnetoelectric transducers and electronic circuits will convert wireless power and data into stimulus patterns that can trigger neural activity in the DRG via miniature electrodes. After chronic demonstration of safety and functionality in large animal models, the team will prepare for regulatory discussions with the FDA. If successful, the EVNS will provide a technology platform for treating other neuropathic pain syndromes.

Novel Implantable Device to Negate Post-Amputation Pain Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NIBIB NOVAFLUX, INC. LABIB, MOHAMED E (contact); KATHJU, SANDEEP Princeton, NJ 2021
NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

Approximately 3.6 million Americans live with an amputated extremity, and the majority of these individuals are likely to suffer from chronic post-amputation pain. There is no consensus as to a recommended therapy for such pain, and many treatments do not provide sufficient pain control. Some studies have shown effective pain suppression from delivering an anesthetic agent directly to an injured nerve. This research aims to develop a device that can be implanted near the injured nerves of an amputated limb to deliver an anesthetic. Findings from this preclinical study will optimize design and delivery features to maximize its effect on pain control for as long as possible without needing a drug refill. The research is expected to advance eligibility for further testing in large animals and humans.

Treating pain in sickle cell disease by means of focused ultrasound neuromodulation Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NIBIB CARNEGIE-MELLON UNIVERSITY HE, BIN Pittsburgh, PA 2019
NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

Researchers will develop a novel transcranial focused ultrasound (tFUS) device for pain treatment and establish its effectiveness for treating sickle cell disease (SCD) pain in humanized mice. The tFUS will target the specific cortical regions involved in SCD pain using a novel non-invasive electrophysiological source imaging technique. The project’s goals have several aims. Aim 1: Develop tFUS devices for pain treatment. The mouse-scale system will be designed to validate the therapeutic effect of stimulating the anticipated cortical targets. This will inform development of the simpler human-scale system, which will use models of the skull to select cost-effective transducers to reach the targets. Aim 2: Evaluate tFUS effectiveness and optimize stimulation parameters in an SCD mice model. Researchers will determine effective tFUS parameters to chronically reduce SCD pain in mice and validate this using behavioral measures. Aim 3: Use electrophysiological source imaging to target and trigger closed-loop tFUS in animal models. This aim also includes performing safety studies to prepare for human trials. The project will develop a transformative, noninvasive tFUS device to effectively and safely treat pain in SCD.

MFMU HEAL Initiative Opportunity: Opioid Prescription Protocols at Discharge after cesarean delivery Clinical Research in Pain Management Pain Management Effectiveness Research Network (ERN) NICHD George Washington University Clifton, Rebecca Washington, DC 2019
NOFO Title: Data Coordinating Center for the NICHD Cooperative Multicenter Maternal Fetal Medicine Units Research Network (U10)
NOFO Number: RFA-HD-13-014
Summary:

Cesarean deliveries are the most commonly performed surgical procedure in the United States. Opioids are almost universally used for post-cesarean analgesia management. Studies suggest that most women are prescribed more tablets at discharge than needed. These often go unused, providing an important reservoir contributing to the opioid crisis. Physicians struggle to prescribe and dose postoperative opioids appropriately while tackling the real needs of acute pain from surgery. Without literature to guide obstetric providers on appropriate amounts of opioids to prescribe upon discharge, actual prescription amounts nationally vary widely by up to 65 tablets. To improve post-cesarean opioid prescribing practices without compromising pain management, the study will test an individualized, patient-empowered approach for pain management and opioid prescription quantity. This is a noninferiority randomized trial of 5,500 women with a cesarean delivery who will be randomized prior to discharge.

A Novel Medical System for Quantitative Diagnosis and Personalized Precision Botulinum Neurotoxin Injection in Chronic Pelvic Pain Management Cross-Cutting Research Small Business Programs NICHD HILLMED, INC. DIAS, NICHOLAS Katy, TX 2021
NOFO Title: HEAL INITIATIVE: Development of Therapies and Technologies Directed at Enhanced Pain Management (R43/R44 - Clinical Trial Required)
NOFO Number: RFA-NS-20-010
Summary:

Chronic pelvic pain affects social and sexual quality of life in up to 20% of women in the United States. It is often managed with physical therapy approaches, but when these measures fail, injection therapies may be indicated. These include injection of botulinum neurotoxin, which leads to muscle relaxation in the pelvic floor and thus pain relief. However, botulinum neurotoxin has dose-dependent side effects and is expensive. Therefore, a precision injection technique to administer botulinum neurotoxin so that it remains effective while minimizing adverse effects and costs is needed. Hillmed Inc. has developed a technique to assess the pelvic floor and choose the optimal injection site, which has improved treatment outcome in initial analyses. They are now aiming to develop a commercializable, personalized precision injection medical device for botulinum toxin and software package that will enable clinicians to optimize botulinum neurotoxin injection. They will then assess the system’s efficacy in a clinical trial of women with chronic pelvic pain and healthy women.

Novel Approach to Personalize and Monitor Therapeutic Training At Home in Chronic Pelvic Pain Management Cross-Cutting Research Small Business Programs NICHD Hillmed, Inc. DIAS, NICHOLAS Katy, TX 2022
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:

Chronic pelvic pain is a debilitating condition that negatively affects the social and sexual quality of life for up to 20% of American women. Pelvic floor muscle (PFM) pain is caused by many factors, as well as by incorrect posture and excessive sensitization of the peripheral nervous system. This project will introduce a prototype of the Chronic Pelvic Pain (CPP) HomeTrainer that monitors, quantitatively and in real time, both PFM activation capacity and muscle interactions between the PFM and hip/trunk muscles and adapts the PFM training to the user’s needs in their own home. The proposed CPP HomeTrainer offers biofeedback to aid myofascial physical therapy and movement pattern training by tailoring the protocol to specifically correct interactions between the PFM and problematic hip/trunk muscles.

CMG2 as a Target for Safe and Effective Treatment of Endometriosis-Associated Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NICHD BOSTON CHILDREN'S HOSPITAL ROGERS, MICHAEL SEAN Boston, MA 2022
NOFO Title: HEAL Initiative: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: NS22-034
Summary:

Endometriosis is an often-painful disorder in which uterine tissue grows outside the uterus. Treatment of endometriosis-associated pain involves use of opioids in many women. This project aims to study a culprit gene thought to be involved with the disorder (capillary morphogenesis gene or CMG2) as a target for new, nonopioid pain medications. The research will also clarify how CMG2 s affects endometriosis-associated pain to test the effects of new medications for endometriosis pain.

Effectiveness of an mHealth psychosocial intervention to prevent transition from acute to chronic postsurgical pain in adolescents Clinical Research in Pain Management Pain Management Effectiveness Research Network (ERN) NICHD SEATTLE CHILDREN'S HOSPITAL RABBITTS, JENNIFER (contact); PALERMO, TONYA M Seattle, WA 2019
NOFO Title: HEAL Initiative: Pain Management Effectiveness Research Network: Clinical Trial Planning and Implementation Cooperative Agreement (UG3/UH3 Clinical Trial Required)
NOFO Number: RFA-NS-19-021
Summary:

The study team developed an mHealth pain self-management intervention for the perioperative period (SurgeryPal) to target psychosocial risk factors and teach pain self-management skills. The goal of this proposal is to establish the effectiveness of the SurgeryPal psychosocial intervention to improve clinically meaningful outcomes in adolescents undergoing major musculoskeletal surgery, and to identify the optimal timing of intervention delivery. The study team will plan for the efficient implementation of a multisite randomized clinical trial at 25 centers in 500 youth ages 12–18 years undergoing spinal fusion surgery and their parents. Participants will be randomized to receive SurgeryPal or attention control condition during the preoperative and postoperative phases. Self-reported pain severity and interference and secondary outcomes will be assessed at baseline, 3-, and 6-months. If effective, this scalable, low cost intervention will allow broad implementation to prevent chronic postsurgical pain in youth.

Peripherally-Restricted Long-Acting Somatostatin Receptor 4 (LA-SSTR4) Agonists for Pain Cross-Cutting Research Small Business Programs NIDA PEPTIDE LOGIC, LLC RIVIERE, PIERRE San Diego, CA 2019
NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44] Clinical Trial Not Allowed)
NOFO Number: PA-18-574
Summary:

The proposed SBIR Phase II program seeks to select a first-in-class, peripherally-restricted, and long-acting somatostatin receptor 4 (LA-SSTR4) agonist clinical candidate for development as a novel non-addictive analgesic able to replace opioids for the treatment of moderate-to-severe chronic pain. The program is based on strong scientific evidence showing that activation of peripheral SSTR4 produces broad spectrum analgesic activity and pursues a unique therapeutic strategy.   Unlike opioids, SSTR4 agonists do not induce constipation, respiratory depression, dependence, addiction, or abuse. Finally, unlike SSTR2 and SSTR5, SSTR4 expression in the pituitary and pancreas is very low, supporting that selective SSTR4 agonists are unlikely to perturb peripheral endocrine functions. The preceding SBIR Phase I program has already established the feasibility of conjugating a short-acting, potent, and selective peptide SSTR4 agonist to the antibody carrier. The resulting LA-SSTR4 agonist lead series has high agonist potency and selectivity for SSTR4 and has demonstrated antinociceptive activity in an animal pain model. The proposed SBIR Phase II program seeks to: optimize the existing lead series and select a clinical candidate for development,  validate and prioritize the indication(s) for clinical development using disease-relevant mouse pain models, and characterize the pharmacokinetics and safety/toxicology profile of the clinical candidate in rat and non-human primates to help design subsequent investigational new drug (IND)-enabling studies.

Long-term activation of spinal opioid analgesia after imflammation - Supplement Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDA University of Pittsburgh TAYLOR, BRADLEY K Pittsburgh, PA 2019
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Severe tissue injury generates central sensitization. Latent sensitization (LS) is a silent form of central sensitization that persists after tissue has healed and overt signs of hyperalgesia have resolved. Pain remission during LS is likely maintained by tonic opioid receptor activity. The opioid receptor inverse agonist, naloxone, can reinstate experimental pain when delivered one week after the resolution of secondary hyperalgesia following first degree thermal injury. Our aims are to test: 1) the hypothesis that burn or surgery triggers LS and long-term opioid analgesia in humans; 2) the hypothesis that mu-opioid receptor (MOR) constitutive activity (MORCA) receptors by opioid peptides maintains endogenous analgesia and restricts LS to a state of pain remission; 3) the extent to which MORs inhibit neural activity in the DH and synaptic strength in presynaptic terminals of primary afferent nociceptors during LS; and 4) whether MORs inhibit spinal NMDA receptor subunits to block pain during LS.

Integrated Treatment for Veterans with Co-Occurring Chronic Pain and Opioid Use Disorder Clinical Research in Pain Management Pain Management Effectiveness Research Network (ERN) NIDA University of New Mexico WITKIEWITZ, KATIE A (contact); VOWLES, KEVIN E Albuquerque, NM 2019
NOFO Title: HEAL Initiative: Pain Management Effectiveness Research Network: Clinical Trial Planning and Implementation Cooperative Agreement (UG3/UH3 Clinical Trial Required)
NOFO Number: RFA-NS-19-021
Summary:

Chronic pain is common, costly, and debilitating. Opioid prescription in the treatment of chronic pain is frequent and carries a consequent risk of poor treatment outcome, as well as higher morbidity and mortality in a clinically significant number of patients, particularly those who meet criteria for opioid dependence. Despite the alarming increases in prescription opiate misuse and opioid use disorder (OUD) nationally in the United States, there are few treatment options available that target both pain-related interference and OUD among patients with chronic pain. In military veterans, this issue is of particular importance as numerous reports indicate frequent use of opioids in the treatment of chronic pain, as well as increasing opioid-related problems. To date, there are no evidence-based treatment options that aim to both reduce pain interference while simultaneously addressing problematic opioid use. The overall aim of this study will be to determine the efficacy of an integrated psychosocial treatment in veterans with chronic pain who are taking buprenorphine for the treatment of OUD. To achieve this aim, they will utilize a randomized design to assess the efficacy of two empirically supported interventions: Acceptance and Commitment Therapy for chronic pain and Mindfulness-Based Relapse Prevention for substance use and misuse.

G Alpha Z Subunit as a Potential Therapeutic Target to Modulate Mu Opioid Receptor Pharmacology Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDA UNIVERSITY OF ROCHESTER BIDLACK, JEAN M Rochester, NY 2022
NOFO Title: Emergency Awards: HEAL Initiative-Early-Stage Discovery of New Pain and Opioid Use Disorder Targets Within the Understudied Druggable Proteome (R21 Clinical Trial Not Allowed)
NOFO Number: TR22-011
Summary:

Opioids affect the body by attaching to certain types of receptors that attach to G-proteins (particularly, a subtype called G-alpha). Opioids vary in their ability to provide pain relief as well as in their ability to require more drug to provide a response, known as tolerance. This project will explore the potential of various G-alpha subunits to increase or decrease opioid receptor signaling. The research findings will lay the groundwork for tailoring G-alpha related opioid effects to provide more pain relief while being less addictive.

Optimized Interventions to Prevent Opioid Use Disorder among Adolescents and Young Adults in the Emergency Department New Strategies to Prevent and Treat Opioid Addiction Preventing Opioid Use Disorder NIDA UNIVERSITY OF MICHIGAN AT ANN ARBOR WALTON, MAUREEN A Ann Arbor, MI 2021
NOFO Title: HEAL Initiative: Notice of Special Interest (NOSI) regarding the Availability of Administrative Supplements to Support Strategies to Increase Participant Diversity, Inclusion and Engagement in Clinical Studies
NOFO Number: NOT-NS-21-025
Summary:

The emergency department is an ideal venue to reach and intervene with adolescents and young adults at risk for opioid misuse, particularly as young adults may disconnect from primary care when transitioning out of care in pediatric settings. This study will evaluate the efficacy of interventions of varying type and intensity to prevent or reduce opioid misuse or opioid use disorder. The research leverages technology that is appealing to youth to facilitate intervention delivery by health coaches. In this study, adolescents and young adults in the emergency department screening positive for opioid use or misuse will be randomly assigned to one of four intervention conditions with outcomes measured at 4, 8, and 12 months. Technology-driven, scalable interventions delivered via health coaches allow for real-time tailoring to the rapidly changing opioid epidemic, with the potential to prevent an increase in opioid misuse among adolescents and young adults.  Black/African American youth are at increased risk for opioid and other substance use, but they often do not participate in research studies. As a result, it is not known how well prevention interventions work with Black/African American people. This supplement will focus on increasing participant diversity and inclusion by recruiting additional Black/African American participants for this ongoing randomized controlled study of technology-driven prevention interventions.

KOR AGONIST FUNCTIONAL SELECTIVITY IN PERIPHERAL SENSORY NEURONS Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDA UNIVERSITY OF TEXAS HLTH SCIENCE CENTER CLARKE, WILLIAM P; BERG, KELLY ANN SAN ANTONIO, TX 2019
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

Functional selectivity is a term used to describe the ability of drugs to differentially regulate the activity of multiple signaling cascades coupled to the receptor. The underlying mechanism for functional selectivity is based upon the formation of ligand-specific receptor conformations that are dependent upon ligand structure. Functional selectivity has the potential to revitalize the drug discovery/development process. Ligands with high efficacy for specific signaling pathways (or specific patterns of signaling) that mediate beneficial effects, and with minimal activity at pathways that lead to adverse effects, are expected to have improved therapeutic efficacy. We propose to demonstrate that ligand efficacy for specific signaling pathways associated with antinociception can be finely tuned by structural modifications to a ligand. We propose to use U50,488 and Salvinorin-A (Sal-A) as scaffolds to develop functionally selective analogs that maintain high efficacy for signaling pathways that lead to antinociception and minimize activity toward anti-antinociceptive signaling pathways.

Role for Tas2Rs in opioid addiction Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDA ICAHN SCHOOL OF MEDICINE AT MOUNT SINAI KENNY, PAUL J. New York, NY 2020
NOFO Title: Notice of Special Interest for HEAL Initiative: Request for Administrative Supplements to Existing Grants for Identification and Validation of New Pain and Opioid Use Disorder Targets within the Understudied Druggable Genome
NOFO Number: NOT-TR-20-008
Summary:

Opioids and other addictive substances have powerful rewarding properties that drive the development of addiction. They also have aversive properties that motivate their avoidance and protect against addiction. This project will explore the role of Type 2 Taste Receptor proteins (Tas2Rs or T2Rs) in regulating the aversive properties of opioids, potentially establishing an entirely new class of receptors that can be targeted for the development of novel addiction therapeutics.

Identification and Validation of a Novel Central Analgesia Circuit Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR DUKE UNIVERSITY WANG, FAN Durham, NC 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:

This project focuses on identifying and validating a new central analgesic circuit in the brain, based on a highly innovative hypothesis that the strong analgesic effects of general anesthesia (GA) are in part carried out by GA-mediated activation of the endogenous analgesic circuits. Preliminary discovery studies found that a subset of GABAergic neurons located in the central amygdala (CeA) become strongly activated and express high levels of the immediate early gene Fos under GA (hereafter referred to as CeAGA neurons). Furthermore, activation of these neurons exert profound pain-suppressing effects in an acute pain model and a chronic orofacial neuropathic pain model in mice. Based on these exciting preliminary findings, this project will identify and validate CeAGA neurons’ analgesic functions utilizing multiple mouse pain models. Identification of these shared common pathways that need to be suppressed by specific subtypes of CeAGA analgesic neurons will be highly critical for developing precise CeAGA-targeted therapies to treat chronic pain.

DE-IMPLEMENTING OPIOID USE AND IMPLEMENTING OPTIMAL PAIN MANAGEMENT FOLLOWING DENTAL EXTRACTIONS Clinical Research in Pain Management NIDCR HealthPartners Institute RINDAL, D. BRAD MINNEAPOLIS, MN 2018
NOFO Title: Implementation Science Research to Improve Dental, Oral and Craniofacial Health (U01)
NOFO Number: RFA-DE-18-001
Summary:

The primary objective of this project is to de-implement the use of opioid analgesics for the management of postoperative pain following dental extractions and to implement effective alternative pain management. We propose a cluster-randomized trial designin which dental practitioners are randomly assigned to one of three conditions: 1) standard practice as a control condition; 2) a clinical decision support (CDS) tool that will extract patient history and interface with the state prescription drug monitoring program to provide personalized recommendations for analgesic prescribing and offer language for discussing non-opioid pain management; 3) an enhanced version of the CDS (CDS-E) that will also include information regarding optimal, evidence-based non-opioid pain management delivered to the patient both before and following the dental extraction visit. We will examine opioid and non-opioid prescribing data from the electronic health record across study arms as well as other provider- and patient-focused outcomes using mixed methods.

Therapeutic in Situ Analgesic Implant for improved Oral-Facial Post-Operative Pain Outcomes Cross-Cutting Research Small Business Programs NIDCR EPIGEN BIOSCIENCES, INC. FRIEDMAN, CRAIG; CAUDLE, ROBERT M San Diego, CA 2019
NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44] Clinical Trial Not Allowed)
NOFO Number: PA-18-574
Summary:

Analgesia for post-operative populations remains a significant health need that calls for innovative therapies which improve both safety and outcome measures. Recent FDA drug safety warnings and studies focusing on post-operative analgesia have highlighted the imperative need for new approaches that can be utilized for common clinical scenarios. Accordingly, novel treatment options that are safe and afford additional benefit in relief of pain are needed. In this proposal, the development of an innovative surgical sealant technology is proposed that functions at the level of the surgical wound bed and actively delivers local pharmacologic agents to therapeutically address post-operative pain. New formulations of several analgesic regimens will be assessed for their ability to seal wounds and provide appropriate pain management.

Validation of blocking TSP4/Cava2d1 interaction as a new target for neuropathic pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR UNIVERSITY OF CALIFORNIA-IRVINE LUO, ZHIGANG DAVID Irvine, CA 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:

Validation of novel pain targets is a critical step toward the development of new non-addictive therapeutic agents for chronic pain management. Recent findings suggest that nerve injury-induced concurrent upregulation of the calcium channel alpha-2delta-1 subunit (CaValpha-2-delta-1) and thrombospondin-4 (TSP4) proteins in sensory and spinal cord neurons contributes to neuropathic pain development. Specifically, induction of aberrant excitatory synapse formation and sensitization of neurotransmission in spinal cord underlies this process; accordingly, a target site has been identified in the TSP4 that plays a critical role in mediating these pathological changes upon interaction with the CaValpha-2-delta-1 protein. This project will validate this novel target site in TSP4 for development of non-addictive pain medications, utilizing multidisciplinary approaches to investigate if blocking and genetic deletion of the target site can block or prevent the development of chronic pain state, aberrant excitatory synapse formation, and spinal cord neuron sensitization after injury in multiple rodent neuropathic pain models.

INVESTIGATION AND MODULATION OF THE MU-OPIOID MECHANISM IN CHRONIC TMD (IN VIVO) Preclinical and Translational Research in Pain Management NIDCR UNIVERSITY OF MICHIGAN AT ANN ARBOR DASILVA, ALEXANDRE ANN ARBOR, MI 2018
NOFO Title: Biology of the Temporomandibular Joint in Health and Disease (R01)
NOFO Number: PA-14-358
Summary:

Initial studies using positron emission tomography (PET) with [11C] carfentanil, a selective radiotracer for ?-opioid receptor (?OR), have demonstrated that there is a decrease in thalamic µOR availability (non-displaceable binding potential BPND) in the brains of TMD patients during masseteric pain compared to healthy controls. ?-opioid neurotransmission is arguably one of the mechanisms most centrally involved in pain regulation and experience. The main goals of our study are: first, to exploit the ?-opioidergic dysfunction in vivo in TMD patients compared to healthy controls; second, to determine whether 10 daily sessions of non-invasive and precise M1 HD-tDCS have a modulatory effect on clinical and experimental pain measures in TMD patients; and third, to investigate whether repetitive active M1 HD-tDCS induces/reverts ?OR BPND changes in the thalamus and other pain-related regions and whether those changes are correlated with TMD pain measures.

LIGHT and Lymphotoxin targeting for the treatment of chronic orofacial pain conditions Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR UNIVERSITY OF TEXAS HLTH SCIENCE CENTER AKOPIAN, ARMEN N San Antonio, TX 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:

Mismanagement of orofacial chronic pain, such as temporomandibular joint and muscle disorders (TMJD) and oral cancer, substantially contributes to opioid overuse; overdose-related deaths; and cardiovascular, renal, and neurological complications at epidemic proportions. The current paradigm implies that orofacial conditions could trigger maladaptation of the immune system and plasticity supporting persistent inflammation, which influences the development and maintenance of orofacial chronic pain. LIGHT (TNFSF14) and Lymphotoxin-beta (LT?), members of the tumor necrosis factor superfamily, provide a balance between protective immunity and immunopathology during chronic inflammatory diseases. This project will test the hypothesis that targeting LIGHT and LT? signaling could prevent the development and inhibit the maintenance of chronic pain produced by TMJD and oral cancer, via peripheral mechanisms involving plasticity of immune, stromal, and tumor cells, as well as sensory neurons. The proposed research is significant as it advances our understanding of mechanisms regulating the development and maintenance of orofacial pain and offers new therapeutic targets and an immunotherapeutic approach for preventing and blocking chronic pain during TMJD and oral cancer.

Targeting HB-EGF and Trigeminal EGFR for Oral Cancer Pain and Opioid Tolerance Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR NEW YORK UNIVERSITY YE, YI New York, NY 2022
NOFO Title: HEAL Initiative: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: NS22-034
Summary:

Oral cancers are painful and often require use of opioid medications to manage pain. However, the effectiveness of opioids often wanes quickly, and many patients require higher doses because they develop tolerance to these medications. This project will study the potential value of blocking epidermal growth-factor receptors interacting with peripheral nerves to treat oral cancer pain. The findings will advance understanding of the molecular mechanisms underlying oral cancer pain and provide a rationale for repurposing epidermal growth-factor receptor blockers, which is already approved for head and neck cancer treatment for treating oral cancer and associated pain.

A Novel Opioid-Free Targeted Pain Control Method for Acute Post-Operative Localized Pain Related to Oral Surgical Procedures Cross-Cutting Research Small Business Programs NIDCR LAUNCHPAD MEDICAL, LLC JADIA, RAHUL; KAY, GEORGE Boston, MA 2019
NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44] Clinical Trial Not Allowed)
NOFO Number: PA-18-574
Summary:

There is a compelling need to develop a front line, non-opioid-based acute pain management strategy for outpatient oral surgical procedures. LaunchPad Medical has developed Tetranite® (TN), a novel bone regenerative mineral-organic self-setting adhesive biomaterial. TN has been extensively studied in vivo in a canine jaw model and shown to be effective and well-tolerated. In this project, researchers will demonstrate that drug-loaded TN can be a novel route to providing localized and time release pain medication following wisdom tooth extraction by determining the release profile of various pain medications from TN at different concentrations. The ability to release pain therapeutics in a controlled fashion and directly at the site of injury offers improved pain control following oral surgical procedures without exposing the patient to opioids. This novel approach to pain management can be extended to more invasive orthopedic procedures such as joint replacement, spinal fusions or reconstructive trauma surgery. In Phase II the team will conduct an in vivo study to assess efficacy of medicated TN to address post-operative pain following wisdom tooth odontectomy, optimize incorporation and release of medications in TN formulations, develop cGMP manufacturing process for the compounded product, and ultimately conduct clinical trials for bone void filler using medicated TN.

Modeling temporomandibular joint disorders pain: role of transient receptor potential ion channels Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDCR Duke University Chen, Yong Durham, NC 2019
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Masticatory and spontaneous pain associated with temporomandibular joint disorders (TMJD) is a significant contributor to orofacial pain, and current treatments for TMJD pain are unsatisfactory. Pain-related transient receptor potential (TRP) channels, expressed by trigeminal ganglion (TG) sensory neurons, have been implicated in both acute and chronic pain and represent possible targets for anti-pain strategies. Using bite force metrics, we found TMJ inflammation-induced masticatory pain to be significantly, but not fully, reversed in Trpv4 knockout mice, suggesting the residual pain might be mediated by other pain-TRPs. Our gene expression studies demonstrated that TRPV1 and TRPA1 were up-regulated in the TG in response to TMJ inflammation in a Trpv4-dependent manner. We hypothesize that TRPV1 and TRPA1, like TRPV4, contribute to TMJ pain. Our specific aims will examine the contribution of TRPV1, TRPV4, and TRPA1 to pathogenesis of TMJD pathologic pain including assessment of the role of neurogenic inflammation.
