NOFO Title: Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
NOFO Number: PA-18-591
Summary:

TWIK-related spinal cord K+ (TRESK) channel is abundantly expressed in all primary afferent neurons (PANs) in trigeminal ganglion (TG) and dorsal root ganglion (DRG), mediating background K+ currents and controlling the excitability of PANs. TRESK mutations cause migraine headache but not body pain in humans, suggesting that TG neurons are more vulnerable to TRESK dysfunctions. TRESK knock out (KO) mice exhibit more robust behavioral responses than wild-type controls in mouse models of trigeminal pain, especially headache. We will investigate the mechanisms through which TRESK dysfunction differentially affects TG and DRG neurons. Based on our preliminary finding that changes of endogenous TRESK activity correlate with changes of the excitability of TG neurons during estrous cycles in female mice, we will examine whether estrogen increases migraine susceptibility in women through inhibition of TRESK activity in TG neurons. We will test the hypothesis that frequent migraine attacks reduce TG TRESK currents.

NOFO Title: Opioid Use Disorder in Pregnancy (R01)
NOFO Number: RFA-HD-18-036
Summary:

This study will challenge current clinical approaches to managing the pregnant woman with opioid use disorder. Dosing of buprenorphine (BUP) in pregnant women is based on studies in non-pregnant subjects, which suggests that symptoms of withdrawal occur when plasma BUP concentrations are < 1ng/ml. No such data exist for pregnant women, but this is a prerequisite for defining an appropriate dosing regimen of BUP in pregnant women. We will define this threshold by monitoring women undergoing mild, medically directed withdrawal. The Clinical Opioid Withdrawal Scale score and the Finnegan score for NAS are key to defining when withdrawal occurs and thus dictate treatment in mother and baby. Neither scoring system is based on plasma BUP concentrations and thus, may not reflect true opioid withdrawal. This proposal aims to develop physiologic-based scoring systems that refine the accuracy of diagnosis and optimize treatment.

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: HEALthy Brain and Child Development Study (HEALthy BCD) (Collaborative R34 Clinical Trial Not Allowed)
NOFO Number: RFA-DA-19-029
Summary:

The Planning for the HEALthy Early Development Study will contribute to the design and recommended protocol for a future large-scale, multi-site research study to prospectively examine human brain, cognitive, behavioral, social, and emotional development of children beginning prenatally through ages 9–10 and to determine the impact of maternal pre- and postnatal substance use on short- and long-term development of children. The planning study will link investigators across 6 research sites who have complementary experience and expertise in the areas that are essential to designing the study. Planning activities will be accomplished using a coordinated set of 10 working groups. By the end of the planning phase, the 6 consortium sites will have produced and tested a recommended protocol for the future multi-site study and will have established feasibility of carrying out the study protocol at each of the 6 linked sites.

NOFO Title: Administrative Supplements for Validation of Novel Non-Addictive Pain Targets (Clinical Trials Not Allowed)
NOFO Number: NOT-NS-18-073
Summary:

Masticatory and spontaneous pain associated with temporomandibular joint disorders (TMJD) is a significant contributor to orofacial pain, and current treatments for TMJD pain are unsatisfactory. Pain-related transient receptor potential (TRP) channels, expressed by trigeminal ganglion (TG) sensory neurons, have been implicated in both acute and chronic pain and represent possible targets for anti-pain strategies. Using bite force metrics, we found TMJ inflammation-induced masticatory pain to be significantly, but not fully, reversed in Trpv4 knockout mice, suggesting the residual pain might be mediated by other pain-TRPs. Our gene expression studies demonstrated that TRPV1 and TRPA1 were up-regulated in the TG in response to TMJ inflammation in a Trpv4-dependent manner. We hypothesize that TRPV1 and TRPA1, like TRPV4, contribute to TMJ pain. Our specific aims will examine the contribution of TRPV1, TRPV4, and TRPA1 to pathogenesis of TMJD pathologic pain including assessment of the role of neurogenic inflammation.

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: Discovery of Biomarkers, Biomarker Signatures, and Endpoints for Pain (R61/R33 Clinical Trial Optional)
NOFO Number: RFA-NS-18-041
Summary:

There is currently no recognized way of accurately predicting who will recover from post-traumatic headache (PTH) during the acute phase following concussion and who will go on to develop persistent post-traumatic headache (PPTH), a condition that is difficult to treat effectively. Clinical experience suggests that early treatment is most effective, before headache patterns become persistent, but treating all patients with PTH would expose some patients to unnecessary treatment. Clinicians lack the information needed to make informed treatment decisions. Therefore, the study goals are to develop a prognostic biomarker signature for PPTH using clinical data and structural and functional brain neuroimaging and to assess the predictive accuracy of an ensemble biomarker signature for the early identification of patients at high risk for PPTH. This study can be translated into clinical practice and integrated into PTH clinical trials for early identification of those individuals who are at high risk for PPTH.

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:

The proposed Fast Track SBIR effort will develop and validate the reliable, low-cost KnowPain instrument. KnowPain will objectively and quantitatively assess the functional impact of chronic pain using measures derived from six degrees-of-freedom motion, heart rate, skin surface temperature, and skin conductivity collected via a specially designed, ergonomic wrist-worn biometric sensing instrument. The new assessment instrument will apply advanced psychometric methods to both physiologic and kinematic data to provide precise scores for functional impairment due to chronic pain. The assessment results will be presented to the clinician in an easy-to-understand report and will include longitudinal results, confidence estimates, and normative data to enable comparisons both within and between patients. The system will include provision to interface with electronic medical records. Accurate functional assessment is a crucial component in the effective treatment of chronic pain. The proposed approach will supplement existing methods for assessing patient function by providing novel and highly complementary information for a more complete (and often unobserved) picture of the impact of chronic pain on patient function. KnowPain measures will provide important data on the practical consequences of pain and on treatment efficacy. 

NOFO Title: HEAL Initiative: Back Pain Consortium (BACPAC) Research Program: Mechanistic Research Centers (U19 Clinical Trial Optional)
NOFO Number: RFA-AR-19-026
Summary:

The University of Michigan (UM) will lead a Mechanistic Research Center (MRC) as part of the broader BACPAC initiative that will take patients with chronic low back pain (cLBP) and use a patient-centric, SMART design study to follow these individuals longitudinally as they try several different evidence-based therapies while mechanistic studies are overlaid to draw crucial inferences about what treatments will work in what patient endotypes. Interventional Response Phenotyping describes the need in any precision medicine initiative to phenotype participants based on what therapies they do and do not respond to so that one can later link mechanistically distinct disease endophenotypes with those who preferentially respond to therapies targeting those mechanisms.

NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: RFA-DA-19-002
Summary:

Naltrexone (NTX) has proven to be an important, safe, and effective therapy for helping patients overcome opioid use disorders (OUD) and for preventing overdose. Unfortunately, the therapeutic potential of NTX has been blunted by poor adherence. To combat this issue, a system must be developed to deliver NTX for longer durations than currently available and with a more patient-friendly format. To address this problem, we will develop a long-acting and bioabsorbable NTX subcutaneous implant for the treatment of OUD. The proposed research will (a) determine the optimal chemical preparation of NTX inside the implant, (b) optimize the composition and porosity of the drug delivery substrate, and (c) refine the surgical procedure and instrumentation to be used during implantation. Once the safety and efficacy of this novel NTX implant is established, we will conduct the necessary clinical trials. The proposed study is highly relevant to and complementary of other efforts, either in consideration or already deployed to stem the tide of the lingering opioid crisis. If successful, this solution has the potential to enhance health, lengthen life, and reduce illness and disability for those suffering from OUD.

NOFO Title: Development of Medications to Prevent and Treat Opioid Use Disorders and Overdose (UG3/UH3) (Clinical Trial Optional)
NOFO Number: RFA-DA-19-002
Summary:

The current studies are designed to examine a novel approach to treating OUD, namely use of a vaccine (OXY-KLH) targeted against oxycodone, one of the most commonly misused prescription opioids, and a vaccine (M-KLH) targeted against heroin/morphine. The researchers will evaluate the safety, immunogenicity, and preliminary efficacy of OXY-KLH and M-KLH. Overall, the proposed studies will provide a great deal of information about the safety and potential efficacy of the vaccines in reducing the addiction liability of opioids, which will be administered in a controlled laboratory setting. If the outcomes of the proposed studies with OXY-KLH and M-KLH are favorable, development of the bivalent vaccine (OXY-KLH plus M-KLH) that will target oxycodone and heroin will proceed. The long-term goal of this research is to develop a multivalent vaccine directed against oxycodone, heroin, and other relevant opioids.
