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
Summary:

A significant gap exists in understanding of the barriers blocking access to specialized care for children of color who experience headaches, as well as to understand and appreciate the impact of undertreatment on a child’s functional ability and quality of life. Long-term, this research aims to understand these barriers to care and test interventions to remedy disparities. As the first step, this project's primary objective is to identify socioeconomic and clinical factors that lead children experiencing headache to seek care in an emergency department in lieu of outpatient neurology care. The results of this research will help to inform efforts to reduce the negative effects of emergency department overuse in this population and guide them to potentially more appropriate outpatient care.

Summary:

Identifying optimal chronic low back pain treatments on a patient-specific basis is an important and unresolved challenge. Tailoring interventions according to patient movement characteristics is one option. This research is characterizing patients based on spinal motion during functional tasks and daily activities and will use artificial intelligence to objectively characterize motions of the spine during both clinical assessments and day-to-day life. During clinical assessments, participants will be asked to perform functional tasks while wearing motion sensors. Data collected from the sensors will be used to identify tasks of interest, such as activities of daily living and aberrant/painful motions. An artificial intelligence approach will then interpret data collected continuously during assessment in patients’ homes over a 7-day testing period. Ultimately, this data could be used to help clinicians tailor treatments that are responsive to a patient’s real-world functional impairments.

Summary:

Social determinants of heath may affect breast cancer diagnosis and disease staging at time of mastectomy. It is unclear if socioeconomic factors such as annual income, marital status/single parent household, number of children, distance from the hospital, and other life stressors facing individuals from under-resourced populations affect development of postmastectomy pain syndrome or response to the drug ketamine. This research will analyze these factors toward mitigating post-mastectomy pain. This analysis will also serve as the basis for further research to define pathways that minimize health disparities plays in the development of chronic, post-surgical pain. The ultimate goal of this research is to normalize risk for chronic pain after breast surgery.

 

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.

NOFO Title: Research Supplements to Promote Diversity in Health-Related Research (Admin Supp - Clinical Trial Not Allowed)
NOFO Number: PA-21-071
Summary:

Knee osteoarthritis is one of the leading causes of chronic pain and disability worldwide, affecting more than 30% of older adults. Rates of this condition have more than doubled in the past 70 years and continue to grow sharply, given increases in life expectancy and body mass index among the U.S. population. This project supports a scientist from a group underrepresented in biomedicine to expand ongoing clinical research comparing various non-medication-based treatments for knee osteoarthritis.

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.

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.

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.

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.

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.
