Subchondral Bone Cavities in Osteoarthritis Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS JOHNS HOPKINS UNIVERSITY CAO, XU; GUAN, YUN Baltimore, MD 2020
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:

A key marker of inflammation in Osteoarthritis (OA) is accompanied by significantly increased sensory innervation within the diseased joint. This study aims to validate the hypothesis that defective bone resorbing cells are responsible for the enlarged bone cavity, giving rise to the inflammatory marker causing further increases in levels sensory innervation and resulting in increased OA pain perception.

Nonpharmacologic Pain Management in FQHC primary care clinics Clinical Research in Pain Management Pragmatic and Implementation Studies for the Management of Pain to Reduce Opioid Prescribing (PRISM) NCCIH UNIVERSITY OF UTAH FRITZ, JULIE M Salt Lake City, UT 2020
NOFO Title: HEAL Initiative: Pragmatic and Implementation Studies for the Management of Pain to Reduce Opioid Prescribing (PRISM) (UG3/UH3, Clinical Trials Optional)
NOFO Number: RFA-AT-20-004
Summary:

Back pain is the most common chronic pain diagnosis and the most common diagnosis for which opioids are prescribed. Clinical practice guidelines make it clear that nonpharmacologic treatments are preferable to opioids for patients with back pain. Despite clear evidence, over-prescribing of opioids to individuals with back pain continues. Providers of nonpharmacologic care are often absent or unreachable from rural and low-income communities and patients with limited financial resources. Many rural and low-income communities are served by Federally Qualified Health Centers (FQHCs) that are at the forefront of the opioid crisis, but often lack adequate options to provide accessible nonpharmacologic treatments. This pragmatic clinical trial will compare the effectiveness of different telehealth strategies to provide effective nonpharmacologic interventions to overcome the barriers specific to serving rural and low-income communities. The trial will evaluate two strategies, one providing both a brief pain teleconsult with phone-based physical therapy, the other uses an adaptive strategy ? providing the brief pain teleconsult first, followed by phone-based physical therapy to those who need additional treatment. The study will also evaluate outcomes related to the efforts to implement strategies in FQHC clinics. This research will provide a toolkit for future efforts to make nonpharmacological interventions for back pain available in other low resource health care settings.

Isolation of GPR160 for biochemical analysis of the activation mechanism and development of a high throughput screening assay to identify small molecule inhibitors Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS SAINT LOUIS UNIVERSITY SALVEMINI, DANIELA Saint Louis, MO 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:

Neuropathic pain conditions are difficult to treat, and novel non-narcotic analgesics are desperately needed. The G protein-coupled receptor 160 (GPR160) has emerged as a novel target for analgesic development, as GPR160 in the spinal cord may play a role in the transition from acute to chronic pain. Cocaine- and Amphetamine-Regulated transcript peptide (CARTp) was identified as a ligand for GPR160. Blocking endogenous CARTp signaling in the spinal cord attenuates neuropathic pain, whereas intrathecal injection of CARTp evokes painful hypersensitivity in rodents through GPR160-dependent extracellular signal-regulated kinase (ERK) and cyclic AMP response element-binding pathways (CREB). This project will isolate and biochemically characterize GPR160 and establish methods for biochemical characterization of GPR160 interaction with CARTp activator. Researchers will miniaturize and optimize biochemical assay and scale up protein production for future high throughput biochemical screening to identify potent inhibitors of GPR160 activation. These studies are critical for defining the molecular mechanism of CARTp/GPR160 interactions and initiating large-scale screens for new inhibitors to develop novel therapeutics.

NOFO Number: NOT-NS-20-044
Summary:

There are numerous non-pharmacological interventions for chronic low back pain, yet no treatment is invariably effective for all. Understanding patient characteristics that predict differential responses to these non-pharmacological interventions will allow for tailored treatments to maximize positive patient impact. This supplement supports a training experience for an individual in clinical pain research, including exploring differential response to psychotherapeutic interventions. The aim of the project is to provide an extensive systematic literature review examining baseline phenotypic factors that predict differential responsiveness to the some of the most commonly used psychotherapeutic interventions for chronic low back pain.

Identification of Novel Targets for the Treatment of Chemotherapy-Induced Painful Peripheral Neuropathy Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF MARYLAND BALTIMORE MELEMEDJIAN, OHANNES KEVORK Baltimore, MD 2020
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:

Chemotherapy-induced painful peripheral neuropathy (CIPN) is the most common toxicity associated with widely used chemotherapeutics. CIPN accounts for significant dose reductions and/or discontinuation of these life-saving treatments. Unfortunately CIPN can also persist in cancer-survivors, adversely affecting their quality of life. CIPN is not well-managed with existing pain therapeutics. Recent preliminary findings suggest that the transcription factor hypoxia-inducible factor alpha (HIF1A) is the target for the chemotherapeutic bortezomib, a proteasome inhibitor. This project will test the hypothesis that bortezomib chemotherapy-induced expression of HIF1A, PDHK1 and LDHA constitute an altered metabolic state known as aerobic glycolysis (AG) that leads to the initiation and maintenance of peripheral neuropathy and pain using a novel tumor-bearing animal model of CIPN. This project aims to validate HIF1A as a therapeutic target for the prevention of CIPN, as well as validate PDHK1 and LDHA as non-opioid therapeutic targets for chronic or established CIPN in animal models.

A Double-Blind, Randomized, Controlled Trial of Epidural Conus Medullaris Stimulation to Alleviate Pain and Augment Rehabilitation in Patients with Subacute Thoracic Spinal Cord Injury (SCI) Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NINDS DUKE UNIVERSITY LAD, SHIVANAND P Durham, NC 2020
NOFO Title: HEAL Initiative: Clinical Devices to Treat Pain (UH3 Clinical Trial Optional)
NOFO Number: RFA-NS-19-018
Summary:

Pain is a major problem for spinal cord injury (SCI) patients that tends to persist and even worsen with time. No treatments are currently available to consistently relieve pain in SCI patients. This study will investigate the feasibility of Epidural Electrical Stimulation (EES) using the Abbott Proclaim? SCS system with two electrodes to treat neuropathic pain in patients with thoracic spinal cord injury. In this double-blind, prospective, randomized clinical trial, patients with subacute, traumatic, complete thoracic SCIs with American Spinal Injury Association (ASIA) Impairment Scale A will be randomized to receive either ?EES on? (treatment intervention) or ?EES off? (control intervention) of the target regions for pain control (lead overlying the spinal cord anatomy corresponding with their pain distribution) and neurorestoration (lead overlying the conus medullaris) as an adjunct to physical therapy. This study will help determine whether EES can help patients with SCI neuropathic pain and have more widespread clinical applicability.

The biophysics of skin-neuron sensory tactile organs and their sensitivity to mechanical and chemical stress Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS STANFORD UNIVERSITY GOODMAN, MIRIAM B Palo Alto, CA 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:

This project will establish a rapid research pipeline for linking plant-derived compounds to nociception (pain) and to G Protein-Coupled Receptors (GPCRs) and ion channels in the druggable human genome. As more than 80% of these membrane proteins are conserved in the C. elegans nematodes, the study will screen for compounds and genes affecting nociception as well as to identify novel ligand-receptor pairs using this model organism. The study will test which understudied GPCRs and ion channels are involved in nociception as well as attraction or repulsion behaviors. This research has the potential to reveal novel ligand-receptor pairs that could serve as new entry points for improved or alternative pain treatments.

NOFO Number: NOT-NS-20-044
Summary:

Pain is one of the most common symptoms in cancer patients and one least likely to be adequately treated. It is particularly common in advanced cancer, affecting an estimated 64% of patients with advanced disease. Pain treatment guidelines state patients should have access to behavioral pain interventions that educate them about pain and teach them skills for managing it. The parent grant will evaluate the effectiveness of an evidence based pain management intervention called ?Pain Coping Skills Training? in a web based format for patients with advanced cancer. This supplement will provide support for a training opportunity that aligns with the goals of the parent grant and includes community outreach and engaging underserved populations in clinical research.

B Lymphocyte-Mediated Autoimmunity in Pain After Trauma Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS PALO ALTO VETERANS INSTIT FOR RESEARCH CLARK, DAVID J Palo Alto, CA 2020
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:

A major recent advancement for the field of pain research is the recognition of immune system dysregulation as a contributor to the most serious adverse consequences of pain from injury. Accumulating data from clinical and laboratory studies place the activation of B lymphocytes at the center of much of this work, particularly with respect to chronic pain and disability-related outcomes. Validation of this B cell hypothesis could lead directly to trials testing the efficacy of novel or existing immunomodulating agents on posttraumatic pain. To achieve these goals a well-validated core mouse model of limb fracture will be employed with additional studies to be conducted in incisional and nerve injury models to broaden the assessment of B cell mediated effects on pain. Age and sex will be included as variables to enhance rigor.

Validation of Spinal Neurotensin Receptor 2 as an Analgesic Target Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF ARIZONA PATWARDHAN, AMOL M Tuscon, AZ 2020
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:

Epidural/spinal administration of analgesics such as opioids, ziconotide and local anesthetics have profound efficacy in some of the most intractable pain conditions such as severe neuropathic pain after failed back surgery, cancer pain and post-operative pain after major abdominal/thoracic surgeries. Contulakin G (CGX) is a snail venom derived peptide that has homology with mammalian neurotensin and was shown to be safe in humans in preliminary studies. A small pilot study demonstrated CGX?s analgesic effect in some patients with spinal cord injury-associated pain. Preliminary findings from mechanistic studies in rodents identified neurotensin receptor 2 (NTSR2) as the mediator for analgesic effects of CGX. This project aims to validate spinal NTSR2 as an analgesic target utilizing three species (rat, mice and human), and two pain models (neuropathic pain and post-surgical pain). The project will utilize pharmacological and gene editing tools such as CRISPR-Cas9 and will include assessment of both sensory and affective measures of pain. A two-site parallel confirmation study is designed based on multisite clinical trials to further authenticate spinal NTSR2 as an analgesic target. Successful completion of this project could lead to the development of a non-opioid spinal analgesic that has high translational potential.

Optimizing the Use of Ketamine to Reduce Chronic Postsurgical Pain Clinical Research in Pain Management Pain Management Effectiveness Research Network (ERN) NINDS NEW YORK UNIVERSITY SCHOOL OF MEDICINE WANG, JING (contact); DOAN, LISA New York, NY 2020
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-20-028
Summary:

Approximately 20% of patients who undergo surgery develop chronic pain, or Chronic Postsurgical Pain (CPSP). CPSP is highly associated with impaired functional recovery and persistent opioid use and dependence, and current standard postoperative multimodal analgesia is only moderately effective for its prevention. This study aims to determine whether the use of ketamine during and/or after surgery prevents Post-Mastectomy Pain Syndrome (PMPS), one of the most common CPSP conditions. Ketamine is a low-risk treatment option that is easy to implement in a wide range of clinical settings. If successful, this treatment could improve postoperative pain management in individuals undergoing mastectomy and help combat the opioid epidemic.

Osteoarthritis Progression And Sensory Pathway Alterations Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIAMS RUSH UNIVERSITY MEDICAL CENTER MALFAIT, ANNE-MARIE Chicago, IL 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:

There is an urgent need for new non-opioid therapeutic agents that treat the pain associated with Osteoarthritis (OA) ? a chronic, progressive disease that leads to pain in weightbearing joints, pain during movement, and pain at rest. This project will refine techniques for targeting several proteins expressed in sensory neurons associated with OA pain, with the goal of testing the potential of these proteins to serve as targets for development of effective, non-opioid painkillers.

Summary:

It is increasingly clear that the microbiome influences psychoneurological symptoms, including pain. This project will support clinical research training focused on examining the relationship between the composition and function of the gut microbiome, including the symbiotic bacteria residing in the gut and their functional gene content, and chronic pain among adults with end-stage kidney disease (ESKD). It provides an opportunity for the trainee to expand his skill set as a pain investigator, through experience in implementing and evaluating pain management interventions in adults with ESKD and chronic pain receiving maintenance hemodialysis. The project aims to determine the acceptability of collecting feces and the feasibility of fecal data collection procedure to determine the best strategies for recruiting research participants from multiple dialysis facilities. These steps will allow the exploration of gene content of the gut microbiota and short-chain fatty acids among people with ESKD on maintenance hemodialysis before and after pain management interventions.

Genetic and Pharmacological Validation of CRMP2 Phosphorylation as a Novel therapeutic Target for Neuropathic Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF ARIZONA KHANNA, RAJESH Tucson, AZ 2020
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:

Peripheral nerve injury-induced upregulation of three axonal guidance phosphoproteins correlates with the development of neuropathic pain through an unidentified mechanism: 1) collapsin response mediator protein 2 (CRMP2); 2) the N-type voltage-gated calcium (CaV2.2); 3) the NaV1.7 voltage-gated sodium channel. Injury induced phosphorylated-CRMP2/CaV2.2 and phosphorylated-CRMP2/NaV1.7 upregulation in the sensory pathway may promote abnormal excitatory synaptic transmission in spinal cord that leads to neuropathic pain states. This project will validate CRMP2 phosphorylation as a novel target in neuropathic pain using innovative tools. Examples include a genetic approach (crmp2S522A) in mice as well as a non-opioid pharmacological approach (a novel CRMP2-phsphorylation targeting compound). Demonstrating that inhibition of CRMP2 phosphorylation reverses or prevents neuropathic pain will promote the discovery and validation of a novel therapeutic target (CRMP2-phosphorylation) to facilitate the development of novel pain therapeutics.

Novel Target Identification for Treatment of Chronic Overlapping Pain Using Multimodal Brain Imaging Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF MARYLAND BALTIMORE TRAUB, RICHARD J; MELEMEDJIAN, OHANNES KEVORK Baltimore, MD 2020
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:

As many as 64% of patients with Temporomandibular Joint Disorders (TMJDs) report symptoms consistent with Irritable Bowel Syndrome (IBS). However the underlying connection between these comorbid conditions is unclear and treatment options are poor. As such, pain management for these Chronic Overlapping Pain Conditions (COPCs) is a challenge for physicians and patients. This project will determine whether the convergence of pain from different peripheral tissues and perceived stress occurs in the brain and elicits a change in central neural processing of painful stimuli. This project will identify and validate specific lipids, enzymes and metabolic pathways that change expression in the brain during the transition from acute to chronic overlapping pain that can be therapeutically targeted to treat COPCs. Multi-disciplinary approaches will be used to combine brain imaging, visualization of spatial distribution of molecules, genetics, pharmacological and behavioral research techniques.

Hybrid Effectiveness-Implementation Trial of Guided Relaxation and Acupuncture for Chronic Sickle Cell Disease Pain Clinical Research in Pain Management Pragmatic and Implementation Studies for the Management of Pain to Reduce Opioid Prescribing (PRISM) NCCIH UNIVERSITY OF ILLINOIS AT CHICAGO DOORENBOS, ARDITH Z (contact); EZENWA, MIRIAM OMELEBELE; MOLOKIE, ROBERT E; SCHLAEGER, JUDITH MICHELLE; SHAH, NIRMISH R Chicago, IL 2020
NOFO Title: HEAL Initiative: Pragmatic and Implementation Studies for the Management of Pain to Reduce Opioid Prescribing (PRISM) (UG3/UH3, Clinical Trials Optional)
NOFO Number: RFA-AT-20-004
Summary:

In the US, approximately 100,000 people, mainly of African and Hispanic background have Sickle Cell Disease (SCD). Pain is a constant companion and chronic disabling symptom for those with SCD. It is increasingly clear that adults with chronic SCD pain also experience periods of acute worsening of their pain. The evaluation of nonpharmacological therapies that reduce chronic pain and the need for opioid medication among individuals with SCD is critically needed to address lack of adequate pain control to prevent periods of acute deterioration and high opioid use with negative sequelae. The investigators will conduct a hybrid type 1 effectiveness-implementation trial to assess the effectiveness of acupuncture and guided relaxation in patients with SCD while observing and gathering information on implementation in three health systems. The study will utilize a 3-arm, 3-site pragmatic randomized controlled SMART trial design that evaluates adaptive interventions, in which selection of interventions responds to patients? characteristics and evolving clinical status. The investigators will use the Consolidated Framework for Implementation Research to plan, execute, and evaluate implementation processes.

Minor Cannabinoids and Terpenes: Preclinical Evaluation as Analgesics Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NCCIH RESEARCH TRIANGLE INSTITUTE WILEY, JENNY L. Research Triangle Park, NC 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:

G-protein coupled receptor 3 (GPR3) is an orphan receptor present in the central nervous system (CNS) that plays important role in many normal physiological functions and is involved in a variety of pathological conditions. Although the brain chemical that activates this receptor has not been identified, work with GPR3 knockout mice has identified GPR3 as a novel drug target for several Central Nervous System (CNS) mediated diseases including neuropathic pain. However, despite the emerging behavioral implications of the GPR3 system, little is known about how GPR3 affects behavior due to the lack of potent and selective chemical probes that allow scientists to examine functioning of the receptor. Recently, two cannabinoid chemicals present in the cannabis plant were discovered as affecting GPR3. This study will modify the chemical structure of these compounds to increase their potency and selectivity so that they may be used as pharmacological tools to investigate the role of GPR3 in modulating pain. In addition, this project focuses on identifying new compounds that show promise for development into therapeutics for the treatment of pain.

UCSF Core Center for Patient-centric Mechanistic Phenotyping in Chronic Low Back Pain Clinical Research in Pain Management Back Pain Consortium Research Program NIAMS UNIVERSITY OF CALIFORNIA, SAN FRANCISCO LOTZ, JEFFREY C. San Francisco, CA 2020
NOFO Title: Notice of Special Interest to Encourage Eligible NIH HEAL Initiative Awardees to Apply for Administrative Supplements to Promote Training in Clinical Research on Pain (Admin Supp ? Clinical Trial Not Allowed)
NOFO Number: NOT-NS-20-044
Summary:

Chronic low back pain is difficult to diagnose and treat effectively in part, because of the interplay of biophysical and psychosocial influences that complicate the relationship between impairment, disability, and pain. Psychological factors such as fear of movement and catastrophyzing can lead to compensatory movement patterns that affect movement biomechanics and paraspinal structure and function, driving further impairment, disrupting the balance between passive and active spine stabilizers, and reinforcing the patient?s perceived disability status. This study will support research to determine how psychological factors, spinal pathology, and perception of pain severity and disability status influence compensatory movement strategies, how movement biomechanics, psychological factors, and pain mechanisms relate to paraspinal muscle quality, and their relative changes during treatment. The supplement will provide training opportunities for skills in clinical pain management research.

Validation of Novel Target for OA Treatment Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF ILLINOIS AT CHICAGO SAMPEN, HEE-JEONG IM; LASCELLES, DUNCAN Chicago, IL 2020
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:

Osteoarthritis (OA) is the most common form of arthritis and a leading cause of pain and disability. Current challenges of managing OA are that there is no OA disease-modifying drug available, there are few effective treatment strategies, and there is an over-reliance on the use of opioids to manage OA-related joint pain. This project aims to validate vascular endothelial growth factor receptors 1 and 2 (VEGFR 1 receptor = Flt1) and (VEGFR 2 receptor = Flk1) as novel therapeutic targets for OA. This is based on a hypothesis that blocking these two specific receptors of VEGF will inhibit cartilage tissue degeneration and alleviate pain symptoms. This study will test the role of VEGFR-1 and -2 in multiple OA animal models using multiple available VEGF inhibitor molecules. The findings from these studies will develop a rationale for future clinical trials to target VEGFR-1 and -2 for OA patients and develop a novel non-addictive treatment for both joint pain and OA pathology.

Non-invasive Nonpharmaceutical Treatment for Neck Pain: Development of Cervical Spine-specific MR-guided Focused Ultrasound System Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NINDS UNIVERSITY OF UTAH RIEKE, VIOLA Salt Lake City, UT 2020
NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

Neck pain is the fourth leading cause of disability and also a significant cause of cervicogenic headaches. Many of the currently available neck pain treatments are invasive with associated risks and complications, particularly because of the complex anatomy. Magnetic resonance guided focused ultrasound, a novel, completely noninvasive technique, can precisely target spinal facet joints to help ameliorate neck pain, potentially transforming the current practices. The goal of this study is to develop a cervical spine-specific device and demonstrate its safety and efficacy on targeting cervical sensory fibers and the third occipital nerve. The results of these studies will provide an understanding on how to best use this technology for chronic neck pain as well as a basis for translation into human use.

The study of Gpr149 in nociception and the peripheral action of minor cannabinoids Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NCCIH UNIVERSITY OF CALIFORNIA, SAN FRANCISCO HELLMAN, JUDITH San Francisco, CA 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:

The cannabis plant contains many active compounds known collectively as cannabinoids that have been shown to possess analgesic and anti-inflammatory properties. These compounds exert their biological activity, in part, through the cannabinoid receptor. The cannabinoid receptor is a member of a class of proteins known as G-protein coupled receptors (GPCRs). This study will test whether a GPCR with unknown biological function, called Gpr149, has a role in the activity of cannabinoids. The study will identify and characterize Gpr149 expression in mouse cells, and deeply characterize the action of minor cannabinoids, endocannabinoids and products of inflammation to modulate Gpr149. This research will provide insight into the analgesic and anti-inflammatory action of minor cannabinoids and into the role of Gpr149 in nociception and the sensitization of nociceptors to inflammatory mediators.

Creating a multi-level intervention to reduce stigma for buprenorphine use for individuals with End Stage Kidney Disease and Chronic Pain Clinical Research in Pain Management Integrated Approach to Pain and Opioid Use in Hemodialysis Patients NIDDK UNIVERSITY OF PITTSBURGH AT PITTSBURGH JHAMB, MANISHA Pittsburgh, PA 2020
NOFO Title: HEAL Initiative: Notice of Special Interest (NOSI) regarding the Availability of Administrative Supplements to Support Strategies to Reduce Stigma in Pain Management and Opioid Use Disorder (OUD) and Treatment
NOFO Number: NOT-OD-20-101
Summary:

Medications have proven to be effective for treating opioid use disorder (OUD). Increasing accessibility to buprenorphine provides an opportunity for many with OUD to benefit from its proven effectiveness. Adherence to medication-based treatments however is low, in part because of the stigma associated with use of this and other effective drugs and as such, leads to inadequate treatment and poor outcomes. This study aims to understand the effects of stigma on patient engagement, retention, and outcomes of buprenorphine treatment. Knowledge drawn from the HIV Stigma Theory and tools developed to reduce HIV associated stigma will be used to assess OUD stigma and to develop interventions to reduce it in the context of buprenorphine treatment. The study findings may provide resources to address stigma and thus maximize treatment adherence among those affected by OUD.

Targeting Endosomal Receptors for Treatment of Chronic Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS COLUMBIA UNIVERSITY HEALTH SCIENCES BUNNETT, NIGEL W; SCHMIDT, BRIAN L New York, NY 2020
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:

Many non-opioid drugs target G Protein-Coupled Receptors (GPCRs), a family of proteins involved in many pathophysiological processes including pain, fail during clinical trials for unknown reasons. A recent study found GPCRs not only function at the surface of nerve cells but also within a cell compartment called the endosome, where their sustained activity drives pain. This study will build upon this finding and test whether the clinical failure of drugs targeting plasma membrane GPCRs is related to their inability to target and engage endomsomal GPCRs (eGPCRs). This study will use stimulus-responsive nanoparticles (NP) to encapsulate non-opioid drugs and selectively target eGPCR dyads to investigate how eGCPRs generate and regulate sustained pain signals in neuronal subcellular compartments. This study will also validate eGCPRs as therapeutic targets for treatment of chronic inflammatory, neuropathic and cancer pain. Using NPs to deliver non-opioid drugs, individually or in combinations, directly into specific compartments in nerve cells could be a potential strategy for new pain therapies.

Validating ASCT2 for the Treatment of Chronic Postsurgical Pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF MARYLAND BALTIMORE MELEMEDJIAN, OHANNES KEVORK Baltimore, MD 2020
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:

Pain associated with surgery is experienced by millions of patients every year. Although post-surgical pain usually resolves as the surgical site heals, up to half of the patients develop chronic pain after surgery. Opioids remain the mainstay treatment for post-surgical pain which are fraught with serious side-effects and abuse liabilities. The endogenous mechanism that leads to the resolution of post-surgical pain remain unclear, specifically the effects of surgery on the metabolism of sensory neurons and how those changes influence the resolution of post-surgical pain are not known. Preliminary findings suggest that surgical trauma suppresses pyruvate oxidation while increased glutamine catabolism was associated with the resolution of post-surgical pain. This project will test the hypothesis that tissue incision and surgery disrupt the expression of the glutamine transporter ASCT2, which then prevents the resolution of post-incisional pain and aims to validate ASCT2 as a therapeutic target. This project will also employ pharmacological, genetic and animal pain model studies test a novel RNA expression-based strategy to enhance ASCT2 expression in DRG sensory neurons and alleviate postoperative pain in animal model systems. Successful completion of this project would validate ASCT2 as a novel endogenous non-opioid and non-addictive mechanism-based target for the resolution of postoperative pain.
