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.

Summary:

An important step for identifying new, non-addictive chronic pain treatments is the search for new, non-opioid molecular targets that reflect the human condition. Recent findings show an increase in levels of two proteins (calcium channel alpha-2delta-1 subunit and thrombospondin) in sensory and spinal cord neurons after nerve injury. This increase is associated with the development of neuropathic pain. This project will determine if chronic injury to key nerve fibers involved in pain cause changes in rat behavior that indicate altered mood. These nerve fibers include the trigeminal nerve that communicates pain, touch, and temperature sensations from the face to the brain and the L5/6 spinal nerves often associated with back and leg pain. This research will also test whether small protein-like molecules (peptides) that block calcium channel alpha-2delta-1 subunit and thrombospondin also block the mood-related behaviors.

NOFO Title: Discovery and Validation of Novel Targets for Safe and Effective Pain Treatment (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-NS-18-043
Summary:

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

NOFO Title: HEAL Initiative: Oral Complications Arising from Pharmacotherapies to Treat Opioid Use Disorders (R01 Clinical Trial Not Allowed)
NOFO Number: RFA-DE-23-015
Summary:

Buprenorphine is commonly used in medication-assisted treatment of opioid use disorders. The U.S. Food and Drug Administration recently issued a warning that the drug may lead to serious tooth damage in some patients. It is thought that high concentrations of the drug in saliva may contribute to tooth damage and decay. This project will use a mouse model of dental caries to explore the mechanism leading to high buprenorphine concentrations in saliva and examine ways to reduce concentrations in the mouth but not the rest of the body; it will also examine buprenorphine’s effects on the bacteria that lead to caries development.

NOFO Number: NS22-034
Summary:

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

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 Number: RFA-DK-18-030
Summary:

In this study, 600 to 700 hemodialysis patients receiving chronic opioids will be randomized across the Hemodialysis Opioid Prescription Effort (HOPE) Consortium to enhanced treatment as usual, buprenorphine therapy, or buprenorphine plus mindfulness-based cognitive therapy intervention delivered by telephone and adapted for pain (MBCT-TP). The following specific aims will be assessed: Aim 1—to assess the effectiveness of buprenorphine in reducing chronic opioid use and prescriptions in hemodialysis patients on opioids at baseline, compared with an enhanced treatment as usual intervention and to assess the effectiveness of buprenorphine in improving pain intensity, quality of life measures, and hospitalizations; Aim 2—to assess the incremental effectiveness of MBCT-TP added to buprenorphine compared with buprenorphine alone on pain interference with physical, social, and mental functioning, opioid use, pain intensity, other quality of life measures, hospitalizations, and mortality.

Summary:

The Pain Reduction and Opioid Medication Safety in ESRD (PROMISE) study aims to improve the safety of opioid use and pain management in end-stage renal disease (ESRD) patients on hemodialysis (HD) using a Type I effectiveness-implementation hybrid design. A multisite randomized controlled trial of HD patients from the Hemodialysis Opioid Prescription Effort (HOPE) Consortium will examine the effectiveness of two separate nine-month evidence-based interventions: 1) Opioid Tapering Management (OTM) and 2) Behavioral Pain Management (BPM). We will examine the effectiveness of OTM (versus no OTM, Aim 1) and BPM (versus no BPM) over nine months for reducing opioid use (primary outcome) and improving pain severity (secondary outcome) in HD patients on chronic opioids. The implementation goal will take advantage of the diverse patient, provider, and organizational settings in the HOPE Consortium to evaluate process outcomes.

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

NOFO Title: Research Project Grant (Parent R01)
NOFO Number: PA-13-302
Summary:

Postoperative ileus (POI) following gastrointestinal (GI) surgery leads to significant patient morbidity and prolonged hospitalizations. Recent studies have demonstrated that intestinal manipulation and surgical trauma activate inflammatory macrophages (M?) and release inflammatory mediators such as nitric oxide (NO) to inhibit intestinal smooth muscle cells in POI. Intestinal M? are a highly heterogeneous and dynamic population in the innate immune system. Preliminary studies show that transient receptor potential vanilloid 4 (TRPV4) channel, a molecular sensor of tissue damage and inflammation, is exclusively expressed by the F4/80+/CD206+ intestinal anti-inflammatory M2 M?. Activation of TRPV4 produces an intestinal contractile response and improves GI transit in a mouse model of POI. The current proposal aims to elucidate the cellular and molecular mechanisms underlying the activation of TRPV4 in the intestinal M2 M?.

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.
