Exacerbation of health disparities has emerged during the COVID 19 pandemic and highlighted the recognition that minority underrepresentation in clinical research may contribute to racial disparities in health outcomes. In clinical trials related to pain, disparities in trial patient inclusion are documented by white patients often being overrepresented. Mitigating these disparities is an area in which an early-career pain investigator training and contributions may have lasting benefits. The pandemic also drove rapid expansion of telehealth for pain management without knowledge of how social and demographic factors affect utilization patterns of this care delivery model. This supplement supports research to examine the extent to which disparities exist in access to and outcomes of telehealth in socially marginalized pain patients. Findings will be applied to enrich the diversity in clinical trial populations for phase 2 safety trials performed in the HEAL EPPIC Network.

A main goal of the NIH HEAL Initiative and the Early Phase Pain Intervention Clinical Network (EPPIC-Net) is to improve non-opioid pain management. This award will leverage the resources at one of EPPIC-Net’s Specialized Clinical Centers by implementing and evaluating strategies to improve the engagement, recruitment, and retention of individuals from underserved racial/ethnic minority populations to participate in EPPIC-Net clinical trials. Since environmental, cultural, and genetic factors may account for observed differences in pain responses between racial and ethnic groups, enrollment of a diverse sample in pain research is crucial to obtain a complete understanding of the effectiveness of any proposed pain therapeutic intervention. The success of these activities will be evaluated, and a toolkit will be created to define best practices that can be by other EPPIC-Net sites and additional trials.

A main goal of the NIH HEAL Initiative and the Early Phase Pain Intervention Clinical Network (EPPIC-Net) is to improve pain management by discovering and validating biomarkers and non-opioid pain medications. This award will leverage the resources at the University of Washington’s EPPIC-Net’s Specialized Clinical Centers by implementing and evaluating strategies to improve the engagement, recruitment, and retention of individuals from underserved racial/ethnic minority populations to participate in EPPIC-Net clinical trials. The site’s network spans multiple states and specialties, allowing access to geographically and demographically diverse patient populations, including underrepresented and underserved populations. 

This research is designed to further understand implementation of medication-delivery programs in jail and/or community treatment programs based on perceptions of staff delivering medications for opioid use disorder and related services. The primary study uses a mainly quantitative approach to examine medication-delivery program implementation in jail and/or treatment settings. The study compliments ongoing research by incorporating a qualitative approach to assess perceptions of diverse staff through two interviews each with 80 individuals working in jail and/or treatment facilities involved in an ongoing study. Qualitative methods will add depth and nuance to our understanding of how medication-delivery programmatic outcomes relate to correctional staff perceptions.

Due to the opioid misuse epidemic across the nation, more infants are being exposed to narcotics during fetal life and developing neonatal opioid withdrawal syndrome (NOWS) in the neonatal period. Critical gaps remain in our knowledge with respect to best practices for identifying and managing infants with NOWS and no large-scale studies have been published on treatments undertaken and later outcomes of infants with NOWS. To address these gaps in knowledge, the Advancing Clinical Trials in Neonatal Opioid Withdrawal Syndrome (ACT NOW) study will evaluate treatment options and improve clinical care of infants with NAS/NOWS. This collaborative effort will conduct two trials: 1) Eating, Sleeping, Consoling for Neonatal Withdrawal (ESC-NOW): a Function-Based Assessment and Management Approach (ESC Study); and 2) Pragmatic, Randomized, Blinded Trial to Shorten Pharmacologic Treatment of Newborns With Neonatal Opioid Withdrawal Syndrome (NOWS) (Weaning Study).

This project aims to develop and clinically validate a 64-channel spinal cord stimulation therapy for treating chronic neuropathic pain of the lower extremities, groin, and lower back. With an increased channel count and the ability to precisely target medial and lateral structures of the spinal cord, the system will treat chronic pain with greater efficacy and reduced side effects. This project will pursue a safe, effective, and non-addictive treatment for neuropathic pain through the testing of enhanced HD64 active leads to be manufactured under GMP regulations. The leads will then undergo electrical, mechanical, biocompatibility, and sterilization testing before being tested in a 10-subject early feasibility study.

There is an urgent unmet need for more efficacious analgesics that act via a non-opioid pathway. Mitogen Activated Protein Kinase-interacting kinase 2 (MNK2) is an enzyme that has been implicated in pain signaling, and there is compelling evidence that inhibiting MNK2 has significant pain-reducing effects with few side-effects. Since MNK2 selective inhibitors have not yet been identified, selective inhibition of MNK2 with a small molecule has not been possible. The development of such compounds will enable studies that will illuminate key differences between MNK2 and MNK1. More importantly, from a therapeutic standpoint, highly selective MNK2 inhibitors may prove to have enhanced efficacy and a more favorable side-effect profile than molecules that inhibit both MNK2 and MNK1. This project will support the design and synthesis of at least one MNK2 inhibitor, with >100-fold selectivity over MNK1, that may be developed into a lead compound for treating neuropathic pain.

Rapid technological advances are leading to field-deployable mobile sensing devices that can quantify complex dynamics of key physical, biological, behavioral, social, and environmental factors, enabling us to understand causation in complex disorders. Significant new investment is needed to develop and disseminate data analytics tools. The Center of Excellence for Mobile Sensor Data-to-Knowledge (MD2K) will generate generalizable theory, methods, tools, and software to address major barriers to processing complex mobile sensor data and its use in biomedical knowledge discovery and just-in-time care delivery. We will develop and implement a standards-based, interoperable, extensible, and open-source big data software platform for efficient implementation of MD2K data analytics. MD2K will demonstrate the feasibility, utility, and generalizability of this approach by implementing the entire MD2K data analytics system in the context of two biomedical applications: reducing relapse among abstinent daily smokers and reducing readmission among congestive heart failure patients

The United States is in the middle of two intertwined epidemics. Suicide and overdose deaths are at record levels. Opioid use disorder and mental illness are major contributors to both, with the highest death rates seen in people with co-occurring disorders (COD). This competitive revision tests whether enhancements to the collaborative care (CC) model adapted for co-occurring disorders improves retention in medication treatment and decreases suicide and overdose risk. The three additional components include: (1) education of family members about addiction and medication treatment; (2) training for family members to administer naloxone and on how to reduce opioid risk behaviors, and (3) implementation of Caring Contacts, a suicide prevention intervention. This study will examine patient and family member attitudes toward overdose education and naloxone in the population with COD; examine and then intervene with family members around patients? use of medication; and test in the COD population the effectiveness of universal suicide and overdose prevention programs.

Pain Coping Skills Training (PCST) uses a cognitive behavioral therapy (CBT) approach to teach patients cognitive and behavioral coping skills shown to reduce pain and pain interference (e.g., relaxation, distraction, cognitive restructuring, activity pacing). Randomized controlled trials show that PCST and similar CBT-based interventions, when delivered in a traditional in-person format, can improve pain and functioning in people with cancer and other conditions. Yet these interventions are underused in clinical care due to barriers such as high resource costs, a shortage of therapists trained to deliver them, and travel requirements for patients. This trial aims to deliver evidence-based behavioral pain interventions such as PCST with methods capable of overcoming barriers currently limiting patient access. This will be investigated using a two-arm trial comparing pain relief with the following interventions: painTRAINER in clinic with eight web-based follow-up sessions; enhanced usual care.
