NOFO Title: HEAL Initiative: Restoring Joint Health and Function to Reduce Pain Consortium (RE-JOIN) (UC2 Clinical Trial Not Allowed)
NOFO Number: RFA-AR-22-009
Summary:

Temporomandibular joint (TMJ) disorders are the most common form of chronic pain in the face and mouth area (orofacial pain), but relatively little is known about the biological causes of these conditions. This project will define the properties of sensory neurons that connect to tissues that make up the TMJ which connects the lower jaw and skull. This research aims to lay groundwork for development of new therapeutic approaches to treat these painful conditions.

NOFO Title: HEAL Initiative: America’s Startups and Small Businesses Build Technologies to Stop the Opioid Crisis (R43/R44 - Clinical Trial Optional)
NOFO Number: RFA-DA-19-019
Summary:

Pain is one of the most common and debilitating symptoms of a wide range of injuries and diseases. Safe and effective alternatives for treating pain that reduce dependence on opioids are, therefore, a primary goal of the NIH. This project proposes a non-invasive, non-pharmacological alternative to treat pain by combining an innovative electroencephalography (EEG)-based Neurofeedback (NF) solution in an immersive virtual reality (VR) environment. NF and VR have been shown to independently produce ameliorative effects on pain, and it is hypothesized that an NF training in VR would have synergistic effects, as VR would distract from pain perception to improve patient compliance in more engaging NF protocols that improve their ability to control pain perception. In the scope of this project, we will initially focus our work on chronic low back pain (cLBP), as this is a growing segment of chronic pain sufferers with a 39 percent worldwide lifetime prevalence, and whose sufferers have historically been heavy users of opiates; later stages of this project will expand this application to address other forms of pain.

NOFO Title: HEAL Initiative: Restoring Joint Health and Function to Reduce Pain Consortium (RE-JOIN) (UC2 Clinical Trial Not Allowed)
NOFO Number: RFA-AR-22-009
Summary:

Pain caused by degenerative joint diseases such as osteoarthritis (OA) is a major public health challenge that significantly affects quality of life for millions of Americans. There are no therapies available that offer pain relief and reverse the course of OA.  This project will use state-of-the-art technologies to create a neuronal connectivity and molecular map of the mouse knee joint, which will help identify molecular signatures that can be targeted for therapy. The research will include animals of different ages and of both sexes and test joint effects after exercise, in animals with OA, and after gene therapy that delivers an experimental OA medication directly to the joint.

NOFO Title: PHS 2018-02 Omnibus Solicitation of the NIH for Small Business Innovation Research Grant Applications (Parent SBIR [R43/R44] Clinical Trial Required)
NOFO Number: PA-18-573
Summary:

With the exception of the Breathalyzer for alcohol, there is currently no available technology that can immediately identify neurologic impairment related to the use of licit or illicit drugs. The presently available methods for detecting opioids—which rely upon analysis of urine, blood, saliva, or hair—are expensive, time-consuming to implement, and can take days to deliver actionable information to meet the “fitness-for-duty” concerns of employers as well as the needs for immediate detection of drug use in the drug rehabilitation and public safety fields. This project intends to develop a non-invasive means of identifying temporary neurological impairment from prescription opioids using analysis of involuntary eye movements. The resultant biometric signature of opioid impairment will be incorporated into Zverex’s existing product library of oculomotor biosignatures, such as marijuana impairment and fatigue.

NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

Neck pain is the fourth leading cause of disability and also a significant cause of cervicogenic headaches. Many of the currently available neck pain treatments are invasive with associated risks and complications, particularly because of the complex anatomy. Magnetic resonance guided focused ultrasound, a novel, completely noninvasive technique, can precisely target spinal facet joints to help ameliorate neck pain, potentially transforming the current practices. The goal of this study is to develop a cervical spine-specific device and demonstrate its safety and efficacy on targeting cervical sensory fibers and the third occipital nerve. The results of these studies will provide an understanding on how to best use this technology for chronic neck pain as well as a basis for translation into human use.

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.

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: HEAL Initiative: Notice of Special Interest (NOSI) regarding the Availability of Administrative Supplements to Support Strategies to Reduce Stigma in Pain Management and Opioid Use Disorder (OUD) and Treatment
NOFO Number: NOT-OD-20-101
Summary:

Increasing primary care clinician intention and behavior to obtain waivers to prescribe buprenorphine for treatment of opioid use disorder and increase use of the Opioid Wizard, a clinical decision support tool, has potential for patient benefit. This supplement will provide support to evaluate a training tool as an intervention to reduce stigma in primary care clinics by integrating a stigma reduction training component into the Opioid Wizard training at multiple sites of the NIDA Clinical Trial Network. Primary care providers will be randomized to novel stigma reduction training, grounded in stigma science, or an attention-control training to determine whether stigma reduction training reduces provider stigma, increases intention to apply for a waiver to prescribe buprenorphine, and ultimately increase the likelihood that providers use Opioid Wizard. The proposed supplement will utilize the randomized controlled trial design embedded in the larger multisite trial to evaluate the Opioid Wizard tool to help primary care clinicians identify, diagnose, and treat patients with opioid use disorder while evaluating the effect of the stigma reduction training.

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:

Some chemotherapy treatments damage nerves outside the brain and spinal cord. This condition, chemotherapy-induced peripheral neuropathy, involves tingling, burning, weakness, or numbness in hands and/or feet and affects nearly 70% of cancer patients receiving chemotherapy. Common pain medications, including opioids, can relieve pain for short intervals but are not suitable for long-term therapy. This project will conduct studies to investigate the safety and tolerability of a novel strategy to treat neuropathic pain: modifying the activity of the dorsal root ganglia, which are nerve cells in the spinal cord that communicate pain signals to and from the brain.

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.

NOFO Title: HEAL Initiative: Translational Development of Devices to Treat Pain (U18 Clinical Trial Not Allowed)
NOFO Number: RFA-EB-18-003
Summary:

Approximately 3.6 million Americans live with an amputated extremity, and the majority of these individuals are likely to suffer from chronic post-amputation pain. There is no consensus as to a recommended therapy for such pain, and many treatments do not provide sufficient pain control. Some studies have shown effective pain suppression from delivering an anesthetic agent directly to an injured nerve. This research aims to develop a device that can be implanted near the injured nerves of an amputated limb to deliver an anesthetic. Findings from this preclinical study will optimize design and delivery features to maximize its effect on pain control for as long as possible without needing a drug refill. The research is expected to advance eligibility for further testing in large animals and humans.

NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements. Parent Grant: HEAL Initiative: Non-addictive Analgesic Therapeutics Development [Small Molecules and Biologics] to Treat Pain (UG3/UH3 Clinical Trial Optional)
NOFO Number: Supplement: PA-20-272; Parent NOFO: NS-21-010
Summary:

Negative allosteric modulators (NAMs) of the metabotropic glutamate (mGlu) receptor, mGlu5, have shown promise for treatment of multiple pain conditions without the serious adverse effects and safety concerns associated with opioids. This project will develop and test a novel series of highly selective mGlu5 NAMs that are structurally unrelated to earlier failed compounds and do not form toxic byproducts as with previous mGlu5 NAMs. A lead candidate is now being characterized in several studies to assess readiness for testing in Phase I clinical studies.
