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

The clinical utility of opioids for pain treatment is limited by its risk for developing opioid usage disorders (OUD). These untoward effects impose a severe burden on society and present difficult therapeutic challenges for clinicians. We propose to extend our cerebral organoid MPS to facilitate the investigation of neuronal response to opioids and identify cellular and molecular signatures in patients vulnerable to OUD. We have assembled a team with complementary expertise in clinical characterization of OUD, cerebral organoid MPS modeling, single cell RNA-seq technology, and functional characterization of neurons in a mesolimbic reward system to test the hypothesis that midbrain MPS is a clinically relevant pre-clinical model for study of opioid usage disorder.

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

While traditional epidural spinal cord stimulation (SCS) for intractable pain has been very efficacious for the patients responsive to it, the success rate has held at approximately 55%. Dorsal root ganglion (DRG) stimulation has shown promise in early trials to provide greater pain relief. Although the decrease in back pain at 3 months was significantly greater in the DRG arm vs. SCS, the adverse event rate related to the device or implant procedure was significantly higher in the DRG arm. Researchers will develop the “Injectrode” system to make the procedure simpler and safer by using an alternative to implantation: using an injectable pre-polymer liquid composite that cures quickly after injection adjacent to the DRG. They will compare an Injectrode-based system with traditional electrode stimulation at the DRG as an alternative to opioid administration. Researchers will perform benchtop characterization and refinement as a precursor to a clinical study, use modeling and animal testing to refine the efficiency of energy transfer from a transcutaneous electrical nerve stimulation unit to an Injectrode/Injectrode collector concept, and optimize the procedure for the complex anatomy of the human DRG.

NOFO Number: PA-18-591
Summary:

As part of an ongoing teleECHO learning collaborative (LC),this study will expand clinical research training in evidence-based quality improvementmethods that were central to delivering and sustaining science-based medication-assisted treatment for opioid use disorder (MOUD) within the Vermont Hub-and-Spoke Model (HSM) with fidelity. Participating primary care practices will be trained in the (1) use of astudy-developedtoolkit of research and evaluationquality improvementmethodsintended to expand provider knowledge and performance in the delivery of evidence-based MOUD, (2) systematic tracking of standardized outcome metrics, and (3) sharing of these standardized data with other LC membersso that practices can use this empirical information to refine their care model over time. The study will measure changes in providers’ knowledge about best practices for MOUD, their comfort in caring for OUD patients with MOUD and their performance on all the standardized outcome metrics.

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

Neuropathic pain is a debilitating affliction present in 26% of diabetic patients, with substantial impact on the quality of life. Despite this significant impact and prevalence, current therapies for painful diabetic neuropathy (PDN) are only partially effective, and the molecular mechanisms underlying neuropathic pain in diabetes are not well understood. Our long-term goal is to elucidate the molecular mechanisms responsible for PDN in order to provide targets for the development of therapeutic agents. Our objective is to identify the molecular cascade linking CXCR4/SDF-1 chemokine signaling to DRG nociceptor hyper-excitability, neuropathic pain, and small fiber degeneration. Our aims will determine: 1) the ion-channel current profile of the nociceptor hyper-excitable state produced by CXCR4/SDF-1 signaling in PDN; 2) the gene expression profile of the nociceptor hyper-excitable state produced by CXCR4/SDF-1 signaling in PDN; and 3) the specific features of nociceptor mitochondrial dysfunction produced by CXCR4/SDF-1 signaling in PDN.

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 Number: PA-18-591
Summary:

The goal of this proposal is to launch an innovative, multi-modal neuroimaging program that will investigate the longitudinal trajectory of the neurodevelopment of irritability across the preschool period. Differentiating clinically salient irritability from developmentally normative temperamental variation has proven to be a difficult task. This is made even more challenging during the preschool period, when irritability has hit its normative peak and measuring neurodevelopment is impeded by methodological constraints. This research will (1) identify specific biomarkers underlying preschool vulnerability for psychopathology by examining neural maturation in executive function as a predictor for clinical outcome; and (2) examine how the parenting environment moderates this vulnerability, with the overarching objective of identifying aberrant irritable trajectories as the foundation for future brain-based behavioral intervention. Primary analyses will (1) probe underlying executive function as a predictor of clinical outcome; and (2) examine parent-child neural synchrony as a predictor of executive function maturation.

NOFO Title: HEAL Initiative Limited Competition: Behavioral Research to Improve MAT: Ancillary Studies to Enhance Behavioral or Social Interventions to Improve Adherence to Medication Assisted Treatment for Opioid Use Disorders (R01 Clinical Trial Optional)
NOFO Number: RFA-AT-19-007
Summary:

Washington state used federal Opioid-STR funding to develop the Washington State Hub and Spoke Model (H&S), an integrated care model to expand access to OUD medications by incorporating primary care and substance use treatment programs, referral organizations, nurse care managers, and care navigators. Based on the initial success, Washington provided more funding and developed a second-generation, low-barrier H&S model, to place medication initiation sites in nontraditional settings, such as emergency departments, syringe exchanges, jails, and homeless shelters, and to have community partners offer OUD medication maintenance. The study will determine the implementation and effectiveness of the new H&S model, maintaining a hybrid effectiveness-implementation approach, and utilizing social network analysis to understand how H&S networks develop to serve the OUD population. The findings will demonstrate what makes the H&S model effective for increasing OUD medication treatment, improving outcomes for people with OUD, and reaching individuals who may not seek treatment.

NOFO Title: The National Drug Abuse Treatment Clinical Trials Network (UG1)
NOFO Number: RFA-DA-15-008
Summary:

According to SAMHSA’s 2017 National Survey on Drug Use and Health (NSDUH), 11.4 million persons in the U.S. report past-year opioid misuse; out of them, only 2.1 million individuals met criteria for an OUD. Very little is known about efficacious interventions for those who do not meet criteria for moderate/severe OUD (i.e., subthreshold OUD). The prevalence of subthreshold OUD in primary care settings is 5 percent to 10 percent, with higher rates (21 percent to 29 percent) among those receiving prescribed opioids. Although they are at high risk of developing moderate/severe OUD and/or dying from an overdose, little or no empirical evidence exists for pragmatic prevention interventions that can be adopted at integrated general medical settings. To study the efficacy of prevention interventions to arrest the progression from risky opioid use, researchers will test the efficacy of a STOP intervention in primary care settings. STOP adopts an early intervention approach, based on a collaborative care model to prevent progression to moderate/severe OUD, and consists of a practice-embedded nurse care manager who provides patient education and supports the primary care provider (PCP) in engaging, monitoring and guiding patients who have risky opioid use; brief advice delivered to patients by their PCP; and phone counseling of patients by behavioral health providers to motivate and support behavior change. Researchers will determine whether STOP reduces risky opioid use and examine the impact of STOP on progression to moderate/severe OUD, overdose risk behavior and overdose events in adults with risky use of illicit or prescription opioids.

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:

This project aims to demonstrate the safety and effectiveness of a novel treatment for opiate addiction using a technique called photobiomodulation, application of light to the forehead. The treatment consists of using a 4-minute application of transcranial photobiomodulation, near-infrared mode, through a supra-luminous LED, to one side of the forehead over the brain hemisphere that has been determined to have a more positive emotional valence. The study will examine differences in opioid cravings, anxiety, depression, and opioid use between participants receiving the treatment and those receiving a sham treatment. We will evaluate patients weekly for safety and efficacy for 3 weeks post-treatment. In Aim II, a highly-regarded product engineer will work with the company to design a marketable product that may have patentable elements.

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

Up to 5 percent of adolescents suffer from high-impact chronic musculoskeletal (MSK) pain, and only about 50 percent with chronic MSK pain who present for treatment recover. Current treatments for chronic MSK pain are suboptimal and have been tied to the opioid crisis. Discovery of robust markers of the recovery versus persistence of pain and disability is essential to develop more resourceful and patient-specific treatment strategies, requiring measurements across multiple dimensions in the same patient cohort in combination with a suitable computational analysis pipeline. Preliminary data has implicated novel candidates for neuroimaging, immune, quantitative sensory, and psychological markers for discovery. In addition, a standardized specimen collection, processing, storage, and distribution system is in place, along with expertise in machine learning approaches to extract reliable and prognostic bio-signatures from a large and complex data set. This project will facilitate risk stratification and a resourceful selection of patients who are likely to respond to current multidisciplinary pain treatment approaches.

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 Pittsburgh Low Back Pain: Biological, Biomechanical, and Behavioral Phenotypes (LB3P) Mechanistic Research Center (MRC) will to perform in-depth phenotyping of patients with chronic low back pain (cLBP), using a multimodal approach to characterize patients and provide insight into the phenotypes associated with experience of cLBP to direct targeted and improved treatments. The LB3P MRC will be formed of three Research Cores, three support cores, and one research project. This approach will leverage and integrate distinctive resources at the University of Pittsburgh laboratories to deliver quantified biomechanical, biological, and behavioral characteristics; functional assessments; and patient-reported outcomes, coupled with advanced data analytics using a novel Network Phenotyping Strategy (NPS). By eliminating isolated and disconnected approaches to treatment and focusing on personalized patient-centric approaches, this approach will yield improved outcomes and patient satisfaction.

NOFO Title: HEAL Initiative: HEALthy Brain and Child Development Study (HEALthy BCD) (R34 Clinical Trial Not Allowed)
NOFO Number: RFA-DA-19-036
Summary:

Structural and functional neuroimaging measures are prone to errors induced by subject motion. Many comorbid features of opioid exposure are likely to increase children’s in-scanner motion. In total, this raises substantial concern that existing neuroimaging methods are not sufficiently motion-robust to be used in studies of children ages 3–5. Researchers will address these concerns with a feasibility study, comparing the existing methods developed for the Adolescent Brain Cognitive Development (ABCD) study with novel methods we will develop and optimize for young children. They will evaluate research methods in a sample of 100 children and test whether novel technologies improve the quality of the raw imaging data and reduce motion biases in the derived measures. Researchers will determine predictors of successful imaging to inform sampling strategies in future studies. The primary outcomes will be novel, validated structural and functional neuroimaging imaging methods for young children and feasibility data to inform the design of future studies addressing developmental questions, particularly those related to opioid exposure.

Summary:

People who use opioids in rural areas suffer worse health and less insurance coverage. The opioid problem in rural areas is of particular concern, as rural areas have higher overdose rates despite equivalent rates of OUD. This is because rural areas have a scant number of clinics and clinicians who provide medication treatment for OUD. Thus, people living in rural areas must travel long distances to access clinics that may or may not have expertise in providing treatment to patients with OUD. Telemedicine (TM) could efficiently increase capacity for delivery of buprenorphine in rural areas and may increase the number of patients receiving medication treatment and improve treatment retention and outcomes. While the development of medication treatments for opioid use disorder (MOUD) capacity in primary care settings with optimal/comprehensive services is desirable, the current opioid crisis with escalating overdose death rates in rural areas suggests a need to implement an efficient, cost-effective system of MOUD services that can be scaled up quickly. The use of a centralized and Medicare-covered TM vendor utilizing a developed methodology and established organizational infrastructure offers the great potential for a rapid rollout to increase access to MOUD and improve treatment retention in rural areas. This cluster randomized clinical trial with two phases will test expanded treatment access to improve retention on MOUD in highly affected rural areas. Phase I will include implementing telemedicine in a limited number of rural sites with varying levels of office-based opioid treatment (OBOT) to inform implementation strategies for the main trial, and Phase II will include evaluate comparative effectiveness between OBOT alone and OBOT + TM at 30 sites.
