Planning Study for the Development of Sigma 2 Ligands as Analgesics Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS UNIVERSITY OF KENTUCKY TIDGEWELL, KEVIN JOSEPH (contact); KOLBER, BENEDICT J Lexington, KY 2023
NOFO Title: HEAL Initiative: Planning Studies for Initial Analgesic Development [Small Molecules and Biologics] (R61 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-21-029
Summary:

Natural products, which are substances found in nature and made by living organisms, have been used in the past as good sources for developing new medications. Natural products isolated from marine bacteria that attach to the pain-signaling protein sigma-2 receptor (also known as transmembrane protein 97 [TMEM97]), may serve as a starting point to create new, non-opioid pain medications. This project will use chemistry and biology approaches to refine such natural products as a treatment for neuropathic pain.

NOFO Title: HEAL Initiative: Early Phase Pain Investigation Clinical Network - Specialized Clinical Centers (U24 Clinical Trials Not Allowed)
NOFO Number: RFA-NS-19-025
Summary:

Managing persistent pain has long been a difficult challenge, one that is heightened by the recent opioid crisis. Although many potential solutions may exist, demonstrating their efficacy in a multicenter trial is a considerable obstacle. There is broad consensus that a nationwide clinical research network is necessary to promote innovation. A hub-spoke complex of academic medical centers with considerable experience in pain management clinical trials and biomarker validation will leverage existing resources to make clinical trial execution efficient and rapid. Together, spokes will provide maximum flexibility, ready to accommodate studies in any well-characterized pain condition.

A Randomized, Double-blind, Placebo-controlled, Parallel, 20-week, Phase 2b Study of Topical Pirenzepine (WST-057) or Placebo in Type 2 Diabetes Mellitus Patients with Painful Diabetic Peripheral Neuropathy Clinical Research in Pain Management Early Phase Pain Investigation Clinical Network (EPPIC-Net) NINDS ICAHN SCHOOL OF MEDICINE AT MOUNT SINAI ROBINSON-PAPP, JESSICA New York, NY 2021
NOFO Title: HEAL Initiative: EPPIC-Net Pain Research - Application for Clinical Trial and Related Activities (OT2)
NOFO Number: OTA-20-008
Summary:

People with diabetes are at risk for painful diabetic peripheral neuropathy. This pain may be experienced as burning, aching, hypersensitivity to touch, or simply as pain, and there are no currently FDA-approved medications that reduce its symptoms. This phase 2 clinical trial, through the EPPIC-NET program, will test a potential new treatment for painful diabetic peripheral neuropathy. The treatment, WST-057 (topical pirenzepine 4%), is a molecule that was developed in the 1980s and marketed throughout Europe and Asia in an oral form to treat gastric ulcers. Studies show that this type of molecule can increase the density of certain nerve fibers, which has been linked with improve patient-reported outcome measures for painful diabetic peripheral neuropathy.

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

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

Novel mGlu5 negative allosteric modulators as first-in-class non-addictive analgesic therapeutics Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS VANDERBILT UNIVERSITY ROOK, JERRI MICHELLE; CONN, P JEFFREY; GEREAU, ROBERT W; LINDSLEY, CRAIG Nashville, TN 2019
NOFO Title: Optimization of Non-addictive Therapies [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-19-010
Summary:

An extensive literature provides compelling evidence that selective antagonists or negative allosteric modulators (NAMs) of the metabotropic glutamate (mGlu) receptor, mGlu5, have exciting potential as a novel approach for treatment of multiple pain conditions that could provide sustained antinociceptive activity without the serious adverse effects and abuse liability associated with opioids. Researchers have developed a novel series of highly selective mGlu5 NAMs that are structurally unrelated to previous compounds, have properties for further development, and avoid the formation of toxic metabolites that were associated with previous mGlu5 NAMs. Based on existing preclinical models, as well as clinical trial data showing efficacy of an mGlu5 NAM in migraine patients, researchers anticipate that their compounds will have broad-spectrum analgesic activity in patients with a variety of chronic pain conditions.

Pre-clinical evaluation of DT-001, a small molecule antagonist of MD2-TLR4 for utility in the treatment of pain Cross-Cutting Research Small Business Programs NINDS DOULEUR THERAPEUTICS, INC. YAKSH, TONY L; CHAKRAVARTHY, KRISHNAN San Diego, CA 2019
NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Technology Transfer Grant Applications (Parent STTR [R41/R42] Clinical Trial Not Allowed)
NOFO Number: PA-18-575
Summary:

 Chronic persistent post-operative pain (CPOP) is a devastating outcome from any type of surgical procedure. Its incidence is anywhere between 20-85% depending on the type of surgery, with thoracotomies showing one of the highest annual incidences of 30-60%. Given that millions of patients (approximately 23 million yearly based on incidence) are affected by CPOP, the results are increased direct medical costs, increased indirect medical costs due to decreased productivity, and associated negative effects on an individual’s physical functioning, psychological state, and quality of life. Given these extensive public health and economic consequences there is a resurgence of research in the area of preventative analgesia.  The goal of this project is to evaluate a novel small molecule antagonist of MD2-TLR4, DT-001 in preclinical models of surgical pain representative of persistent post-operative pain. In collaboration with University of California, San Diego, DT-001 will be evaluated for its ability to block the development of neuropathic pain states. These studies will evaluate dose escalating efficacy of DT001 in rats in formalin and spinal nerve injury (SNI) models using both intrathecal and intravenous routes of administration. Tissues will be preserved to assess functional effects on relevant pain centers for analysis by Raft. With demonstration of efficacy, these studies will determine the optimal dose and route of administration of DT001 and guide a development path to IND and eventually clinical trials.

Drug Free Nerve Block Device for the Relief of Pain and Symptoms in Migraines and other Headaches Cross-Cutting Research Small Business Programs NINDS THERMAQUIL, INC. POPIELARSKI, STEPHEN (contact); YUAN, HSIANGKUO Philadelphia, PA 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:

Migraines and other headaches are often debilitating for patients, yet few treatment options providing sustained relief exist. All available therapies, including frequently prescribed opioids, have considerable side effects or limitations. Therefore, novel treatment approaches are needed to reduce or eliminate the need to use opiates and other systemic pharmaceuticals. Thermaquil Inc. has developed a new way of stopping migraine and other headache pain by noninvasively blocking pain signal transmission in the head, which in initial studies allowed patients to discontinue use of opioids and other addictive pain medications. Thermaquil will now be conducting a larger randomized controlled trial to demonstrate the safety and effectiveness of this novel approach. After a baseline period, patients will be randomly assigned to the active or control condition and receive a single treatment. The study will continue for 12 weeks with the active versus control arms, before all patients will be given active therapy for an additional 12 weeks.

Development of an intranasal, direct to nerve treatment for headache disorders Cross-Cutting Research Small Business Programs NINDS Olfax, LLC BECKWITH, JONATHAN G (contact); COOK, JASON T Asheville, NC 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:

About 14% of U.S. adults report experiencing migraine symptoms within any given 3-month period, making it the second most disabling illness in the world. Nonspecific pain medications used in migraine (e.g., acetaminophen, nonsteroidal inflammatory drugs, opioids) are often not effective for severe migraine symptoms or cause significant adverse effects. A research team of migraine care specialists, device and drug developers, and clinical research specialists has created a technology for accurately delivering self-administered migraine medication to the upper nasal cavity. The technology enables development of a self-administered therapy to provide rapid pain relief without harsh and addictive side effects of existing migraine medications. This project will establish efficacy and evaluate commercial design feasibility for this treatment.

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.

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.

Immune Modulating Therapies to Treat Complex Regional Pain Syndrome Preclinical and Translational Research in Pain Management Discovery and Validation of Novel Targets for Safe and Effective Treatment of Pain NINDS DREXEL UNIVERSITY AJIT, SEENA Philadelphia, PA 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:

Complex regional pain syndrome is a difficult-to-treat chronic condition that causes excess and prolonged pain and inflammation after injury to an arm or leg and includes damage to skin of affected limbs. Although it is known that aberrant immune system function plays a role in this condition, the details remain unclear about how this occurs – in particular, through the adaptive immune system that relies on specialized immune cells and antibodies to protect the body from harm.  This project will study the role of certain immune cells (T cells) that circulate throughout the body or reside in bone using both rat or human bone samples from patients with complex regional pain syndrome.

Development of Positive TMEM97 Modulators for Treating Neuropathic Pain Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS NUVONURO, INC. MARTIN, STEPHAN Austin, TX 2023
NOFO Title: HEAL Initiative: Non-addictive Analgesic Therapeutics Development [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Optional)
NOFO Number: RFA-NS-21-010
Summary:

Neuropathic pain is a debilitating and complex medical condition for which safe and non-addictive treatment options are urgently needed. This project aims to develop new strategies for treating neuropathic pain by controlling the activity of transmembrane protein 97 (TMEM97), also known as the sigma 2 receptor, which has been shown to relieve pain in an animal model of neuropathic pain. The research aims to develop a new molecule that increases TMEM97 activity and is safe for human use, toward obtaining approval from the U.S. Food and Drug Administration for Phase I clinical testing.

Peripherally Restricted Non-Addictive Cannabinoids for Cancer Pain Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS UNIVERSITY OF CALIFORNIA LOS ANGELES SPIGELMAN, IGOR (contact); CAHILL, CATHERINE M; FAULL, KYM FRANCIS; SCHMIDT, BRIAN L; SPOKOYNY, ALEXANDER MICHAEL Los Angeles, CA 2023
NOFO Title: HEAL Initiative: Non-addictive Analgesic Therapeutics Development [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Optional)
NOFO Number: RFA-NS-21-010
Summary:

Oral cancer pain is debilitating and difficult to treat, in part because even the most effective available pain remedies are limited by side effects. Opioid-based pain medications have several side effects including dependence and tolerance, in which the body gets used to a medicine so that either more medicine is needed or different medicine is needed. Another side effect is hyperalgesia, in which people taking opioids become more sensitive to certain painful stimuli and may misuse the drugs and risk addiction. This project will evaluate lab-made versions of cannabinoid molecules known to block pain signals in nerve cells, but which cannot enter the brain to cause neurological side effects. The research aims to advance promising versions of the molecules to testing in human research participants.

Multisite adaptive brain stimulation for multidimensional treatment of refractory chronic pain Preclinical and Translational Research in Pain Management Translating Discoveries into Effective Devices to Treat Pain NINDS UNIVERSITY OF CALIFORNIA, SAN FRANCISCO SHIRVALKAR, PRASAD San Francisco, CA 2019
NOFO Title: HEAL Initiative: Clinical Devices to Treat Pain (UH3 Clinical Trial Optional)
NOFO Number: RFA-NS-19-018
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.

Inhibiting RIPK1 with Necrostatin-1 for Safe and Effective Pain Treatment Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS Massachusetts General Hospital SHEN, SHIQIAN (contact); HOULE, TIMOTHY T; WANG, CHANGNING ; ZHANG, CAN MARTIN Boston, MA 2022
NOFO Title: HEAL Initiative: Planning Studies for Initial Analgesic Development [Small Molecules and Biologics] (R61 Clinical Trial Not Allowed)
NOFO Number: NS21-029
Summary:

Recent studies have reported that neuropathic pain involves changes in the central nervous system that are linked to necroptosis (programmed necrotic cell death) and release of cellular components that create neuroinflammation. Necroptosis is a type of necrotic cell death affected by the protein receptor-interacting serine/threonine-protein kinase 1 (RIPK1 or RIP1). Preliminary studies also indicate that pain increases levels of RIPK1 in key brain regions implicated in pain processing. This project aims to further validate RIPK1 as a target for neuropathic pain using a newly developed positron emission tomography imaging approach. The work will pave the way for new brain-penetrant RIPK1 inhibitors as a safe, effective, and nonaddictive treatment approach for neuropathic pain.

Investigating the Contributions of Voltage Gated Sodium Channels to Oxaliplatin Induced Neuropathy Cross-Cutting Research Training the Next Generation of Researchers in HEAL NINDS UNIVERSITY OF CALIFORNIA AT DAVIS YAROV-YAROVOY, VLADIMIR M Davis, CA 2022
NOFO Title: Notice of Special Interest to Encourage Eligible NIH HEAL Initiative Awardees to Apply for PA-20-222: Research Supplements to Promote Diversity in Health-Related Research (Admin Supp - Clinical Trial Not Allowed)
NOFO Number: NOT-NS-20-107; PA-21-071
Summary:

Many molecular gates known as ion channels control the flow of electrical signals to sensory neurons and are thus key mechanisms and targets for understanding and interrupting pain signals. Recent breakthroughs in structural and computational biology shave illuminated specific molecular shapes of ion channels, which permits the improved design and refinement of small, stable protein-like molecules (peptide antigens). These peptides can stimulate an immune response that can then be targeted with a bioengineered antibody to match the peptide antigen. This project will test bioengineered antibodies in a rat model of chemotherapy-induced peripheral neuropathy within a region of the rat spinal cord that transmits signals to and from the brain.

Site-directed RNA editing of Nav1.7 as a novel analgesic Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS MARINE BIOLOGICAL LABORATORY, WOODS HOLE ROSENTHAL, JOSHUA J C (contact); DIB-HAJJ, SULAYMAN D; DUSSOR, GREGORY O; EISENBERG, ELI New Haven, CT 2021
NOFO Title: HEAL Initiative: Team Research for Initial Translational Efforts in Non-addictive Analgesic Therapeutics Development (U19 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-21-015
Summary:

Opioids are widely used pain treatments, despite their relative ineffectiveness for chronic pain and their high potential for misuse and addiction. There is thus an urgent need for alternative, non-addictive pain treatments. Genetic and functional studies of human pain disorders and animal models of pain have validated Nav1.7, a voltage-gated sodium channel as an attractive target for new pain treatments. Currently available blockers of these channels can sometimes provide symptomatic relief for patients but have worrisome side effects affecting the brain and heart. This study aims to develop and validate an innovative site-directed RNA editing strategy that will offer the ability to create new versions of molecules to block Nav1.7, toward establishing a novel, non-addictive approach to treat chronic pain.

Novel HCN1-selective small molecule inhibitors for the treatment of neuropathic pain Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS WEILL MEDICAL COLL OF CORNELL UNIV GOLDSTEIN, PETER A New York, NY 2019
NOFO Title: Optimization of Non-addictive Therapies [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-19-010
Summary:

Neuropathic pain is characterized by neuronal hyperexcitability and spontaneous activity, properties associated with activity of hyperpolarization-activated, cyclic nucleotide-regulated (HCN1-4) channels, the source of the pacemaker current, Ih. Inhibition of HCN1-mediated Ih elicits marked antihyperalgesia in multiple animal models of neuropathic pain, including models for direct nerve injury and chemotherapy-induced peripheral neuropathy, and does so with little or no disruption to either normal pain processing or baseline behaviors and activities. The overall objective is to develop a peripherally restricted HCN1 inverse-agonist as a therapeutic for neuropathic pain. Researchers have generated a novel small molecule that combines an antihyperalgesic HCN1 inhibitor with a motif that controls distribution and membrane presentation and is a potential non-opioid antihyperalgesic treatment for peripheral neuropathic pain.

Micronized salsalate in a parenteral formulation is a safe and effective analgesic for acute postoperative pain management Cross-Cutting Research Small Business Programs NINDS RH NANOPHARMACUETICALS L.L.C. ROSS, JOEL STEVEN Monmouth Beach, NJ 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 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.

Optimization of non-addictive biologics to target sodium channels involved in pain signaling Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS UNIVERSITY OF CALIFORNIA AT DAVIS YAROV-YAROVOY, VLADIMIR M Davis, CA 2019
NOFO Title: Optimization of Non-addictive Therapies [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-19-010
Summary:

Pain signals originate predominantly in a subset of peripheral sensory neurons that harbor a distinct subset of voltage-gated sodium (NaV) channels; however, current NaV channel blockers, such as local anesthetics, are non-selective and also block NaV channels vital for function of the heart, muscle, and central nervous system. Genetic studies have identified human NaV1.7, NaV1.8, and NaV1.9 channel subtypes as key players in pain signaling and as major contributors to action potential generation in peripheral neurons. ProTx-II is a highly potent and moderately selective peptide toxin that inhibits human NaV1.7 activation. This study will optimize ProTx-II selectivity, potency, and stability by exploiting the new structures of ProTx-II—human NaV1.7 channel complexes, advances in rational peptide optimization, and rigorous potency and efficacy screens to generate high-affinity, selective inhibitors of human NaV1.7, NaV1.8, and NaV1.9 channels that can define a new class of biologics to treat pain.

Development of selective calpain-1 inhibitors for chronic pain Cross-Cutting Research Small Business Programs NINDS 1910 GENETICS, INC. NWANKWO, JENNIFER Cambridge, MA 2021
NOFO Title: HEAL Initiative: Development of Therapies and Technologies Directed at Enhanced Pain Management (R43/R44 – Clinical Trial Not Allowed)
NOFO Number: NS-20-011
Summary:

The need to develop non-opioid therapeutics for chronic pain is greater than ever.  One option being explored is inhibiting the activity of calpains – enzymes that have been shown to cause pain in animal models of chronic pain.  Using an artificial intelligence (AI)-driven drug discovery platform, researchers have uncovered and validated four calpain-1 inhibitors using biochemical assays.  This study by 1910 Genetics Inc. hopes to synthesize multiple analogs of its most potent discovered calpain-1 inhibitor and determine its effectiveness against calpain-2 and certain enzymes that break down proteins.  Findings that successfully significantly inhibit calpain-1 in at least one animal model of chronic pain could lead to the first oral, central nervous system penetrating selective calpain-1 inhibitor [non-opioid therapeutic] for chronic pain.

Allosteric Targeting of Cannabinoid CB1 Receptor to Develop Non-Addictive Small Molecule Analgesics Preclinical and Translational Research in Pain Management Development and Optimization of Non-Addictive Therapies to Treat Pain NINDS Texas A&M Health Science Center LU, DAI (contact); SELLEY, DANA E; TAO, FENG College Station, TX 2022
NOFO Title: HEAL Initiative: Non-addictive Analgesic Therapeutics Development [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Optional)
NOFO Number: RFA-NS-21-010
Summary:

Overreliance on opioids to treat chronic pain has been a contributor to the increase in individuals experiencing opioid addiction. This project aims to develop an innovative treatment approach for chronic pain that targets the cannabinoid receptor 1 (CB1R) to block the sensation of pain. The approach seeks to identify molecules that interact with a different part of the CBR1 receptor than do endocannabinoids and the primary active component of cannabis, tetrahydrocannabinol. Molecules that bind to and activate CBR1 in this different way (at an “allosteric” site) may produce nerve signaling that might differ from the effects of cannabis and endocannabinoids. This redirection of signaling pathways could help eliminate the risk of adverse effects observed with natural cannabinoids and other CBR1-binding molecules. The goal of this project is to identify a CB1R allosteric molecule, conduct studies toward obtaining federal permission to develop it as a medication, and to test it in a Phase I clinical study.
