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 study aims to determine whether a subset of understudied genes that are expressed in human and mouse dorsal root ganglia (DRG) tissues (critical for relaying the sensation of pain from the body to the central nervous system), are also expressed in human induced pluripotent stem cell DRG mimetics. The study will also determine if these genes are involved in neuronal excitability changes under inflammatory conditions and compare these responses to those of primary DRG neurons. Third and finally, the study will optimize genetic depletion of target genes enabling future fundamental and preclinical research studies.

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:

Exacerbation of health disparities has emerged during the COVID 19 pandemic and highlighted the recognition that minority underrepresentation in clinical research may contribute to racial disparities in health outcomes. In clinical trials related to pain, disparities in trial patient inclusion are documented by white patients often being overrepresented. Mitigating these disparities is an area in which an early-career pain investigator training and contributions may have lasting benefits. The pandemic also drove rapid expansion of telehealth for pain management without knowledge of how social and demographic factors affect utilization patterns of this care delivery model. This supplement supports research to examine the extent to which disparities exist in access to and outcomes of telehealth in socially marginalized pain patients. Findings will be applied to enrich the diversity in clinical trial populations for phase 2 safety trials performed in the HEAL EPPIC Network.

NOFO Title: PHS 2017-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44])
NOFO Number: PA-17-302
Summary:

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

NOFO Title: HEAL Initiative: Integrated Approach to Pain and Opioid Use in Hemodialysis Patients: The Hemodialysis Opioid Prescription Effort (HOPE) Consortium - Clinical Centers (U01 Clinical Trial Required)
NOFO Number: RFA-DK-18-030
Summary:

This study will collaborate with diverse stakeholders to design and conduct a multisite trial evaluating innovative strategies to reduce opioid dosing and improve quality of life and experience with care specific to pain management among adults receiving in-center hemodialysis. A pragmatic parallel arm trial will test the impact of adding a 12-week interactive video cognitive behavioral therapy (IV-CBT) intervention program, compared with CDC guideline-concordant shared decision-making (SDM) for NCCP pharmacotherapy management. The specific aims are to (1) conduct a multisite randomized trial to receive IV-CBT and SDM versus SDM alone over 15 months; (2) investigate and describe barriers and facilitators of the implementation of IV-CBT and also SDM among patients, clinicians, and dialysis staff; and (3) create a collaborative network of investigators and dialysis facilities for efficient recruitment and for dissemination of successful strategies to optimize pain care in dialysis.

NOFO Title: HEAL Initiative: Pain Management Effectiveness Research Network: Clinical Trial Planning and Implementation Cooperative Agreement (UG3/UH3 Clinical Trial Required)
NOFO Number: RFA-NS-19-021
Summary:

To enhance availability of cognitive behavioral therapy for chronic pain (CBT-CP), this study will 1) refine strategies to identify and recruit patients, finalize intervention procedures, and ensure data infrastructure and quality; 2) determine the effectiveness of online and telephonic CBT-CP on patients and pain severity and secondary outcomes, including depression, sleep, quality of life, and pain-related health care utilization, from the electronic health record; and 3) assess the cost and incremental cost-effectiveness of online and telephonic CBT-CP compared with usual care. Eligible participants will be randomized to one of two painTRAINER interventions or usual care. Interventions will be eight weekly 45-minute sessions of the online program or telehealth-style phone coaching by trained behavioral health specialists. Self-reported pain severity and secondary outcomes will be assessed at baseline and at three, six, and 12 months.

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:

Effective treatments are elusive for the majority of patients with neuropathic pain. Reactive oxygen and nitrogen species (ROS/RNS) are involved in neuropathic pain, because they drive mitochondrial dysfunction, cytokine production, and neuronal hyperexcitability; therefore, stimulation of endogenous antioxidants is predicted to simultaneously resolve multiple neuropathic pain mechanisms. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that is a potential therapeutic target because it regulates the expression of a large number of endogenous antioxidant-related genes and can be activated with a single drug. This project will test the hypothesis that Nrf2 activation increases multiple endogenous antioxidants, therefore reversing neuropathic pain behaviors and counteracting neuropathic pain mechanisms that are driven by ROS/RNS and could provide an effective pain therapy, with minimal abuse/addictive potential.

NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH, CDC, and FDA for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44] Clinical Trial Not Allowed)
NOFO Number: PA-18-574
Summary:

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

NOFO Title: HEAL Initiative: Back Pain Consortium (BACPAC) Research Program Technology Research Sites (UH2/UH3 Clinical Trial Optional)
NOFO Number: RFA-AR-19-028
Summary:

Despite the significance of spine disorders, there are few reliable methods to determine appropriate patient care and evaluate intervention effectiveness. The research and tool development take the critical next step in the clinical translation of faster, quantitative magnetic resonance imaging (MR) of patients with lower back pain. The multidisciplinary Technology Research Site (Tech Site) of BACPAC will develop Phase IV (i.e., technology optimization) technologies and/or methods (TTMs) to leverage two key technical advancements: development of machine learning-based, faster MR acquisition methods and machine learning for image segmentation and extraction of objective disease related features from images. The team will develop, validate, and deploy end-to-end deep learning-based technologies (TTMs) for accelerated image reconstruction, tissue segmentation, and detection of spinal degeneration to facilitate automated, robust assessment of structure-function relationships between spine characteristics, neurocognitive pain response, and patient-reported outcomes.

NOFO Title: Blueprint Neurotherapeutics Network (BPN): Small Molecule Drug Discovery and Development for Disorders of the Nervous System (U44 Clinical Trial Optional)
NOFO Number: PAR-18-541
Summary:

We propose to develop a safe and effective nonopioid analgesic to treat neuropathic pain that targets an isoform of the voltage-gated sodium ion channel, NaV1.7. Voltage-gated sodium channels are involved in the transmission of nociceptive signals from their site of origin in the peripheral terminals of DRG neurons to the synaptic terminals in the dorsal horn. NaV1.7 is the most abundant tetrodotoxin-sensitive sodium channel in small diameter myelinated and unmyelinated afferents, where it has been shown to modulate excitability and set the threshold for action potentials. Development of systemic NaV1.7 inhibitors has been complicated by the challenge of achieving selectivity over other NaV isoforms expressed throughout the body. We have discovered a series of potent, state-independent NaV1.7 inhibitors that exhibit >1000-fold selectivity over other human isoforms. Work conducted under this program will support advancement of a lead candidate into clinical development as a therapeutic for neuropathic pain.

NOFO Title: HEAL Initiative: Optimization of Non-addictive Therapies [Small Molecules and Biologics] to Treat Pain - (U44 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-19-020
Summary:

MNK-eIF4E signaling is activated in nociceptors upon exposure to pain or peripheral nerve injury, promoting cytokines and growth factors and increasing nociceptor excitability, which leads to neuropathic pain. Genetic or pharmacological inhibition of MNK signaling blocks and reverses nociceptor hyperexcitability as well as behavioral signs of neuropathic pain. A clinical phase drug for cancer shows strong specificity as an MNK inhibitor but requires optimization because MNK inhibition in the central nervous system (CNS) may lead to depression, an unacceptable side effect for a neuropathic pain drug. The research team plans a targeted medicinal chemistry and screening campaign directed at generating a MNK-inhibitor-based neuropathic pain treatment with the goal of restricting its CNS penetration while retaining potency, specificity, and in vivo bioavailability and efficacy.

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:

Most of the 200k Americans who undergo thoracotomy each year receive opiates to reduce postoperative pain because clinicians have few non-addictive, cost-effective choices to control the severe pain patients often experience in the first two weeks after surgery. Managing pain post-thoracotomy is critical to enable patients to take deep breaths and remove (via coughing) lung secretions that otherwise significantly increase risk of pneumonia and collapsed lung, hospital re-admission and morbidity. The most severe pain associated with thoracotomy is transmitted along the intercostal nerves, but no long-term analgesic or nerve block device exists that can provide safe and effective long-term reduction of pain. A reversible, patient-controlled, non- addictive, intercostal nerve block device would reduce suffering due to thoracotomy, broken ribs and herpes zoster. In this Phase I project, the team will develop a minimally invasive thermal nerve block device that can control nerve conduction by gently warming and cooling a short nerve segment between room temperature and warm water temperature. This novel approach is based on the discovery that warm and cool temperature mechanisms of nerve block are different and additive, enabling moderate-temperature nerve block by cycling neural tissues slightly above and below body temperature. Reversible thermal nerve blocks represent a completely new approach to managing pain.

NOFO Title: HEAL Initiative: Pragmatic and Implementation Studies for the Management of Pain to Reduce Opioid Prescribing (PRISM)(UG3/UH3 Clinical Trial Optional)
NOFO Number: RFA-AT-19-004
Summary:

Prescriptions for narcotic pain relief after surgery result in unintended prolonged opioid use for hundreds of thousands of Americans. Nonpharmacological pain care is effective and recommended by guidelines for perioperative pain while offering a more favorable risk-benefit ratio. However, nonpharmacological pain care is rarely used as first or second-line therapy after surgery. Patient and clinician decision support interventions are effective in encouraging patient-centered and guideline-concordant care, but these strategies have not been tested pragmatically as a bundle in everyday postoperative pain care. The NOHARM trial will first confirm the feasibility of patient-facing and clinician-facing decision support components of an EHR-embedded evidence-based bundle. The investigators will test the bundle in a stepped-wedge cluster randomized trial. They will test a sustainable system strategy that could change the paradigm of perioperative pain management toward nonpharmacological options in a manner that preserves patient function, honors patient values, and maintains availability of opioids as a last resort.
