A phenotypic screen for osteoarthritic pain therapeutics using all-optical electrophysiology Cross-Cutting Research Small Business Programs NIAMS QUELL TX, INC. LIU, PIN; MCMANUS, OWEN B Cambridge, 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:

 Quell Therapeutics uses the Optopatch platform for making all-optical electrophysiology measurements in neurons at a throughput sufficient for phenotypic screening. Using engineered optogenetic proteins, blue and red light can be used to stimulate and record neuronal activity, respectively. Custom microscopes enable electrophysiology recordings from 100’s of individual neurons in parallel with high sensitivity and temporal resolution, a capability currently not available with any other platform screening technology. Here, researchers combine the Optopatch platform with an in vitro model of chronic pain, where dorsal root ganglion (DRG) sensory neurons are bathed in a mixture of inflammatory mediators found in the joints of osteoarthritis patients. The neurons treated with the inflammatory mixture become hyperexcitable, mimicking the anticipated cellular pain response. Investigators calculate the functional phenotype of arthritis pain, which captures the difference in action potential shape and firing rate in response to diverse stimuli. The team will screen for small molecule compounds that reverse the pain phenotype while minimizing perturbation of neuronal behavior orthogonal to the pain phenotype, the in vitro “side effects.” The highest ranking compounds will be chemically optimized and their pharmacokinetic, drug metabolism, and in vivo efficacy will be characterized. The goal is to advance therapeutic discovery for pain, which may ultimately help relieve the US opioid crisis.

AIBP and regulation of neuropathic pain Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS Univ. of Calif., U.C. San Diego Miller, Yury La Jolla, CA 2018
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Persistent pain states arising from inflammatory conditions, such as in arthritis, diabetes, HIV, and chemotherapy, exhibit a common feature in the release of damage-associated molecular pattern molecules, which can activate toll-like receptor-4 (TLR4). Previous studies suggest that TLR4 is critical in mediating the transition from acute to persistent pain. TLR4 as well as other inflammatory receptors localize to lipid raft microdomains on the plasma membrane. We have found that the secreted apoA-I binding protein (AIBP) accelerates cholesterol removal, disrupts lipid rafts, prevents TLR4 dimerization, and inhibits microglia inflammatory responses. We propose that AIBP targets cholesterol removal to lipid rafts harboring activated TLR4. The aims of this proposal are to: 1) determine whether AIBP targets lipid rafts harboring activated TLR4; 2) test whether AIBP reduces glial activation and neuroinflammation in mouse models of neuropathic pain; and 3) identify the origin and function of endogenous AIBP in the spinal cord.

Validation of peripheral CGRP signaling as a target for the treatment of pain in chronic pancreatitis Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NIDDK JOHNS HOPKINS UNIVERSITY PASRICHA, PANKAJ J Baltimore, MD 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:

Chronic pancreatitis (CP) and the debilitating pain associated with it remains a common and challenging clinical syndrome that is difficult to treat effectively. Using rodent models of CP, preliminary studies have found that nerve growth factor (NGF) and transforming growth factor beta (TGFb) appear to be acting by the common effector, calcitonin-gene related peptide (CGRP), to induce pain in CP. CGRP is known to mediate pain as a neurotransmitter in the central nervous system, specifically as a potent vasodilator involved in migraine. This project will test the hypothesis that peripheral CGRP is a major mediator of peripheral nociceptive sensitization in CP, and that peripherally restricted anti-CGRP treatment could provide an efficient and sufficient approach for the treatment of pain in pancreatitis

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.

Clustering of individual and diverse ion channels together into complexes, and their functional coupling, mediated by A-kinase anchoring protein 79/150 in neurons Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS UNIVERSITY OF TEXAS HLTH SCI CTR SAN ANTONIO SHAPIRO, MARK S San Antonio, TX 2018
NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Multi-protein complexes have emerged as a mechanism for spatiotemporal specificity and efficiency in the function and regulation of cellular signals. Many ion channels are clustered either with the receptors that modulate them or with other ion channels whose activities are linked. Often, the clustering is mediated by scaffolding proteins, such as AKAP79/150. We will probe complexes containing AKAP79/150 and three different channels critical to nervous function: KCNQ/Kv7, TRPV1, and CaV1.2. We will use"super-resolution" STORM imaging of primary sensory neurons and heterologously expressed tissue-culture cells, in which individual complexes can be visualized at 10–20 nm resolution with visible light. We hypothesize that AKAP79/150 brings several of these channels together to enable functional coupling, which we will examine by patch-clamp electrophysiology of the neurons. Since all three of these channels bind to AKAP79/150, we hypothesize that they co-assemble into complexes in neurons and that they are dynamically regulated by other cellular signals.

Long-acting ghrelin for neuropathy Cross-Cutting Research Small Business Programs NINDS EXTEND BIOSCIENCES, INC. SOLIMAN, TARIK Newton, 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 need for safe, effective, well- tolerated drugs to treat painful neuropathy by halting or reversing the underlying pathology of the disease. One promising approach to treating painful neuropathy without opioids is the use of ghrelin, a 28-amino acid acylated peptide hormone. However, it has a short half-life and must be delivered via a constant intravenous infusion to have a therapeutic effect. Extend Biosciences' D-VITylation platform technology is truly enabling for small peptide-based therapeutics that are rapidly cleared from the bloodstream by renal filtration. The platform harnesses the naturally long half-life of vitamin D and its dedicated binding protein, VDBP. When the vitamin D molecule is conjugated to a biological therapeutic, it dramatically improves the half-life and bioavailability of the drug. Use of the technology should also allow the drug to be self-administered by subcutaneous injection. This would be of significant benefit to patients. In this project, the team will test the efficacy of EXT405 in a cell-based model of neuropathy as well as in animal models of CIPN and diabetes- induced neuropathy.

Proof of concept study to treat negative affect in chronic low back pain Clinical Research in Pain Management Back Pain Consortium Research Program NIAMS UNIVERSITY OF PITTSBURGH AT PITTSBURGH WASAN, AJAY D Pittsburgh, PA 2019
NOFO Title: HEAL Initiative: Back Pain Consortium (BACPAC) Research Program: Phase 2 Clinical Trials (UG3/UH3 Clinical Trial Required)
NOFO Number: RFA-AR-19-029
Summary:

The chronic low back pain (cLBP) subgroup with comorbid depression or anxiety disorders, known as high negative affect (NA), needs better non-opioid, comprehensive pain treatment options. Data shows that the combination of antidepressants (AD) and fear avoidance physical therapy is more efficacious at improving pain, function, depression, and anxiety in cLBP patients with high NA than each treatment alone or a control condition. Research also finds that an enhanced fear avoidance rehabilitation protocol (EFAR; fear avoidance-based physical therapy, pain education, and motivational messaging) further improves outcomes. To address the unmet needs of cLBP patients with high NA, this study will test in a randomized trial whether the combination of AD and EFAR is more effective than each treatment alone at relieving pain, improving function, combating depression, and preventing opioid misuse. This multimodal combination approach of pharmacotherapy and behavioral therapy is novel to the field and has the potential to shift current treatment paradigms.

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.

hiPSC-based DRG Tissue Mimics on Multi-well Microelectrode Arrays as a Tissue Chip Model of Acute and Chronic Nociception Preclinical and Translational Research in Pain Management Translational Research to Advance Testing of Novel Drugs and Human Cell-Based Screening Platforms to Treat Pain and Opioid Use Disorder NCATS UNIVERSITY OF TEXAS DALLAS BLACK, BRYAN JAMES Dallas, TX 2019
NOFO Title: HEAL Initiative: Tissue Chips to Model Nociception, Addiction, and Overdose (UG3/UH3 Clinical Trial Not Allowed)
NOFO Number: RFA-TR-19-003
Summary:

Researchers will develop an innovative three-dimensional (3D) model of acute and chronic nociception using human induced pluripotent stem cell (hiPSC) sensory neurons and satellite glial cell surrogates. They will develop a tissue chip for modeling acute and chronic nociception based on 3D hiPSC-based dorsal root ganglion tissue mimics and a high-content, moderate-throughput microelectrode array. Researchers will demonstrate stable spontaneous and noxious stimulus-evoked behavior in response to thermal, chemical, and electrical stimulation challenges. They aim to demonstrate sensitivity to translational control via ligand receptor interactions between neuronal and non-neuronal cell types. They also will demonstrate the quantitative efficiency and preclinical efficacy of our system by detecting known ligand-based modulators of translational control and voltage-gated ion channel antagonists in a sensitized model of chronic nociception. Researchers will leverage the high-throughput nature of our tissue chip model to screen Food and Drug Administration–approved bioactive compounds.

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, YUQING SAINT LOUIS, MO 2019
NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
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.

NOVEL THERAPEUTIC AGENTS FROM THE BACTERIAL SYMBIONTS OF BRAZILIAN INVERTEBRATES Preclinical and Translational Research in Pain Management FIC HARVARD MEDICAL SCHOOL CLARDY, JON; PUPO, MONICA T Boston, MA 2018
NOFO Title: Limited Competition: International Cooperative Biodiversity Groups (U19)
NOFO Number: RFA-TW-13-001
Summary:

An International Cooperative Biodiversity Group with an interdisciplinary leadership team of physicians, pharmacologists, evolutionary biologists, and chemists will discover and develop therapeutic agents produced by Brazilian symbiotic bacteria. The team will target three therapeutic areas: 1) infectious fungal pathogens, 2) Chagas disease and leishmaniasis, and 3) cancers of the blood. All three areas represent major threats to human health that need to be addressed with new therapeutic agents. Internationally, invasive fungal diseases kill more people than malaria or TB, while Chagas disease imposes a special burden on Brazil, killing as many Brazilians as TB. Leishmaniasis has now passed Chagas disease in the Brazilian population. Despite major improvements in cancer chemotherapy, cancer is projected to result in 8 million deaths internationally this year (13% of all deaths, WHO) and an estimated 13 million per year by 2030.

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.

Sympathetic-mediated sensory neuron cluster firing 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 JOHNS HOPKINS UNIVERSITY DONG, XINZHONG Baltimore, MD 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:

An important component of neuropathic pain is spontaneous or ongoing pain, such as burning pain or intermittent paroxysms of sharp and shooting pain, which may result from abnormal spontaneous activity in sensory nerves. However, due to technical limitations, spontaneous activity in sensory neurons in vivo has not been well studied. Using in vivo imaging in genetically-modified mice, preliminary findings identified spontaneously-firing clusters of neurons formed within the dorsal root ganglia (DRG) after traumatic nerve injury that exhibits increased spontaneous pain behaviors. Furthermore, preliminary evidence has been collected that cluster firing may be related to abnormal sympathetic sprouting in the sensory ganglia. This project will test the hypothesis that cluster firing is triggered by abnormal sympathetic inputs to sensory neurons, and that it underpins spontaneous paroxysmal pain in neuropathic pain models. Findings from this project will identify potential novel therapeutic targets for the treatment of neuropathic pain.

Joint Pain on a Chip: Mechanistic Analysis, Therapeutic Targets, and an Empirical Strategy for Personalized Pain Management Preclinical and Translational Research in Pain Management Translational Research to Advance Testing of Novel Drugs and Human Cell-Based Screening Platforms to Treat Pain and Opioid Use Disorder NCATS UNIVERSITY OF PITTSBURGH AT PITTSBURGH GOLD, MICHAEL S (contact); LIN, HANG Pittsburgh, PA 2019
NOFO Title: HEAL Initiative: Tissue Chips to Model Nociception, Addiction, and Overdose (UG3/UH3 Clinical Trial Not Allowed)
NOFO Number: RFA-TR-19-003
Summary:

The research team developed an in vitro multi-component joint on a chip (microJoint), in which engineered osteochondral complexes, synovium, and adipose tissues were integrated. This study will introduce sensory innervation into the microJoint and a neuron-containing microfluidic ally will be developed to innervate the microJoint. The osteoarthritis (OA) model will be created in the Neu-microJoint system. The research team will assess activation and/or sensitization of nociceptive afferents with electrophysiology, as well as neurite outgrowth. They will mechanically insult the Neu-microJoint and assess the emergence of “pain” in response to prolonged mechanical stress. Researchers will assess the impact of drugs used clinically for management of OA on OA models and will then use “omic” approaches to identify new biomarkers and therapeutic targets. Researchers will assess the impact of opioids—which they hypothesize will increase the rate of joint degeneration and potentiate the release of pain-producing mediators—on neural activity in the presence and absence of joint injury, as well as the integrity of all joint elements.

EXPLORATION, CONSERVATION, & DEVELOPMENT OF MARINE BIODIVERSITY IN FIJI AND THE SOLOMON ISLANDS Preclinical and Translational Research in Pain Management FIC GEORGIA INSTITUTE OF TECHNOLOGY HAY, MARK E ATLANTA, GA 2018
NOFO Title: Limited Competition: International Cooperative Biodiversity Groups (U19)
NOFO Number: RFA-TW-13-001
Summary:

This International Cooperative Biodiversity Group application aims to discover and develop small molecule drug leads from cultured marine microbes and diverse coral reef organisms collected from Fiji and the Solomon Islands. Drug discovery efforts will focus on four major disease areas of relevance to the United States and low- and middle-income countries: infectious disease, including tuberculosis and drug-resistant pathogens; neglected tropical diseases, including hookworms and roundworms; cancer; and neurodegenerative and central nervous system disorders. Screening in these therapeutic areas will be performed in collaboration with two major pharmaceutical companies, two highly respected academic groups, and various testing centers and government resources that are available to facilitate drug discovery and development. The acquisition of source material for this program will be linked to biotic surveys, informed by ecological investigations addressing the chemical mediation of biotic interactions, and enriched using ecology-based strategies designed to maximize secondary metabolite production and detection.

NOFO Number: PA-18-574
Summary:

New approaches that can effectively ameliorate acute and chronic migraine pain are urgently needed. Due to its critical roles in inducing migraine pain, CGRP and its receptor complex, the calcitonin receptor-like receptor (CLR) and receptor activity-modifying protein 1 (RAMP1) have been targeted for migraine treatment. A new strategy for targeting the CGRP-mediated signaling pathway is needed to meet the medical need of migraine patients. The team developed a group of long-acting CGRP/RAMP1-specific peptide super-antagonists that form gels in situ in aqueous solution. Based on this exciting finding, the investigators propose to develop and identify the most potent antagonistic analog candidates (Aim 1), and characterize the pharmacokinetics of gel depots made of the selected candidates in vivo (Aim 2). This feasibility study is needed to explore the translational potential of these newly invented super-antagonists for the treatment of chronic migraine in combination with conventional migraine agents.

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.

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.

Repression of Sodium Channels via a Gene Therapy for Treatment of Chronic Neuropathic Pain Cross-Cutting Research Small Business Programs NINDS NAVEGA THERAPEUTICS, INC. MORENO, ANA MARIA; ALEMAN GUILLEN, FERNANDO 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:

Voltage-gated sodium channels are responsible for the transmission of pain signals. Nine genes have been identified, each having unique properties and tissue distribution patterns. Genetic studies have correlated a hereditary loss-of-function mutation in one human Na+ channel isoform – ?Na?V?1.7 – with a rare genetic disorder known as Congenital Insensitivity to Pain (CIP). Individuals with CIP are not able to feel pain without any significant secondary alteration. Thus, selective inhibition of ?Na?V?1.7 in normal humans could recapitulate the phenotype of CIP. This research team developed a non-permanent gene therapy to target pain that is non-addictive (because it targets a non-opioid pathway), highly specific (only targeting the gene of interest), and long-term lasting (around 3 weeks in preliminary assays in mice). During this Phase I , the team will 1) test additional pain targets ?in vitro?, and 2) evaluate the new targets ?in vivo ?in mice models of inflammatory and neuropathic pain.

Summary:

Postoperative pain is a major contributor to the current opioid epidemic. Novel objective measures capable of personalizing pain care will enhance medical precision in prevention and treatment of postoperative pain. This project seeks to discover and validate a novel biosignature of the human pain experience, based on underlying IL-1 family cytokine activity and associated brain endogenous opioid function, that is readily quantifiable and clinically translatable to prevention and treatment of postoperative pain states. Specific aims will assess whether the novel biosignature will predict 1) experimentally induced pain during an experimental nociceptive pain challenge; 2) postoperative pain states with accuracy >75%, accounting for a wide range of variance in the human pain experience; and 3) postoperative pain states in an expanded clinically enriched sample.

Summary:

There is an unmet need for an effective parenteral/oral analgesic for acute post- operative pain management without the risks of opioid addiction. Salsalate, a dimer or salicylic acid, is currently available in oral dosage for the treatment of osteoarthritis and rheumatoid arthritis. Salsalate works at multiple levels to target multiple steps along the surgical pain pathway. Salsalate through its active metabolite, salicylic acid (SA), reduces NF-?B activation via IKK-kinase beta inhibition, and has no direct binding to cyclooxygenase 1 (Cox-1); therefore, does not affect function of platelets, resulting in a safer hematological and gastrointestinal safety profile. RH Nano proposes a plan for manufacturing and pre- clinical testing of parenteral M-salsalate in two animal models to assess the efficacy and safety in the treatment of acute postoperative pain management. In this proposal, the team will develop the optimal formulation under strict Chemistry Manufacturing and Control guidelines. In Phase II, the team proposes to conduct the pharmacokinetics and toxicology studies of M-salsalate in two species of animals (rodent and non-rodent). Additionally, the project will use an animal pain model for preclinical efficacy studies, and an in vivo Receptor Occupancy assay in animal brain tissues to assess the opioid sparing properties of M-salsalate.

Summary:

The research team will develop stimulation control algorithms to treat chronic pain using a novel device that allows longitudinal intracranial signal recording in an ambulatory setting. Subjects with refractory chronic pain syndromes will undergo bilateral surgical implant of temporary electrodes in the thalamus, anterior cingulate, prefrontal cortex, insula, and amygdala to identify candidate biomarkers of pain and optimal stimulation parameters. Six patients will proceed to chronic implantation of “optimal” brain regions for long-term recording and stimulation. The team will first validate biomarkers of low- and high-pain states to define neural signals for pain prediction in individuals. They will then use these pain biomarkers to develop personalized closed-loop algorithms for deep-brain stimulation (DBS) and test the feasibility of closed-loop DBS for chronic pain in weekly blocks. Researchers will assess the efficacy of closed-loop DBS algorithms against traditional open-loop DBS or sham in a double-blinded cross-over trial and measure mechanisms of DBS tolerance.
