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.

Given the severity of the current opioid crisis, there is a pressing need to maximize the effectiveness of our interventions and increase retention in medication for opioid use disorder (MOUD) treatment. Measurement-based care (MBC), in which patient progress is regularly and systematically assessed to aid in treatment decisions, is a promising approach. Assessment tools are needed that can be administered quickly and that yield information that can be used to suggest improvements in treatment. In this study, the Investigator will conduct a series of analyses with data from the Brief Addiction Monitor (BAM), which has been selected for a national MBC initiative within the Veterans Administration. The goal of the work will be to derive and validate two new scales from the BAM. One scale is intended for use in opioid use disorder (OUD) specialty care programs. The second version is intended for use in primary care–based MOUD.

The study team developed an mHealth pain self-management intervention for the perioperative period (SurgeryPal) to target psychosocial risk factors and teach pain self-management skills. The goal of this proposal is to establish the effectiveness of the SurgeryPal psychosocial intervention to improve clinically meaningful outcomes in adolescents undergoing major musculoskeletal surgery, and to identify the optimal timing of intervention delivery. The study team will plan for the efficient implementation of a multisite randomized clinical trial at 25 centers in 500 youth ages 12–18 years undergoing spinal fusion surgery and their parents. Participants will be randomized to receive SurgeryPal or attention control condition during the preoperative and postoperative phases. Self-reported pain severity and interference and secondary outcomes will be assessed at baseline, 3-, and 6-months. If effective, this scalable, low cost intervention will allow broad implementation to prevent chronic postsurgical pain in youth.

Chronic low back pain (CLBP) is a problem affecting millions of Americans. Psychosocial approaches are efficacious for addressing the multidimensional nature of CLBP. Three of the most widely implemented nonpharmacological techniques for CLBP management are cognitive therapy (CT), mindfulness meditation (MM), and behavioral activation (BA). However, there is a critical lack of research examining if these techniques work via the mechanisms specified by theory. Ecological momentary assessment (EMA) and ActiGraph technology embedded within a randomized controlled trial, consisting of daily measures of process and outcome, is ideal for testing mechanism models both during treatment and during the critical period following treatment. The current proposal seeks to utilize EMA and ActiGraph to examine if changes in cognitive content, cognitive process, and activity level are mechanisms specific to CT, MM, and BA, respectively, for reducing pain interference. Elucidating the mechanisms of pain coping skills will lead to streamlined CLBP interventions.

The Helping to End Addiction Long-term? (HEAL) Initiative’s Early Phase Pain Investigation Clinical Network (EPPIC-Net) is a unique opportunity to impact the management of pain, through expeditious discovery and validation of biomarkers and analgesic therapies, and in-depth phenotyping. The University of Washington’s (UW) Division of Pain Medicine (UW Pain; “hub”) includes four core clinical sites. Committed spokes include specialty care clinics, primary care clinics, external academic medical centers, and health systems. To achieve the goals of the HEAL Initiative’s EPPIC-Net, the study group will (1) establish UW EPPIC-Net hub and spokes infrastructure, provide scientific leadership and administrative oversight, and apply expertise in design and conduct of high-quality multidisciplinary Phase 2 clinical trials and biomarker validation studies; (2) develop policies and procedures for rapid design, initiation, recruitment, conduct, and closure of high-quality multidisciplinary Phase 2 clinical trials and biomarker validation studies for specific pain conditions at UW Pain EPPIC-Net hub and spokes; and (3) establish mechanisms for communication, education and training, and performance assessment of the UW-EPPIC-Net hub and spokes, to assure efficient and timely utilization of resources to most effectively recruit research participants into EPPIC-Net.

Non-steroidal anti-inflammatory drugs (NSAIDs) are a first line pharmacologic pain therapy for chronic musculoskeletal pain, and rheumatoid arthritis (RA) and moderate to severe osteoarthritis (OA) specifically. However, insufficient pain relief by NSAID monotherapy has encouraged the use of combination therapy. Combinations of NSAIDs plus weak opioids are widely used although objective evidence for efficacy is limited and they have many adverse events.  A growing body of evidence suggests that ?2/?3 subtype-selective positive allosteric modulators (PAM) of the ?- aminobutyric acid A receptor (GABAAR) may effectively restore central pain regulatory mechanisms thus providing effective relief of chronic pain with reduced prevalence and severity of side-effects.  Based on these promising preliminary studies and considerable supporting literature data, the research team will test the hypothesis that combination dosing of TPA-023B with an NSAID will work synergistically to suppress the acute and chronic pain components of chronic musculoskeletal pain. 

The research team will develop HD64—a high-resolution, 64-channel spinal cord stimulation therapy to provide more pain relief for those suffering from chronic neuropathic pain and opioid dependence. HD64 provides an ultra-thin conformal blanket of stimulation contacts across the width of the spinal cord and enables more precise targeting of the lateral structures of the spinal cord to enhance pain relief. A cadaveric pilot run followed by a non-significant risk intraoperative study will be performed to inform the design parameters of HD64 arrays. The study will evaluate activation of medial and lateral spinal targets. At the end of Phase 1, the clinical feasibility of HD64 surgical leads will be established. In Phase 2, researchers will develop an external active lead pulse generator and charger. They will perform an early feasibility study human trial using active HD64 and mechanical and electrical design verification testing and chronic safety studies in large animals.

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 a need for longer-acting prophylactic pharmacologic options for opioid use disorder (OUD) patients during maintenance therapy. This study tests a titanium implant loaded with a formulation of naltrexone and a naturally occurring carboxylic acid. The device is implanted subcutaneously with local anesthetic during an in-office procedure. The technology is based on a unique formulation that keeps the pH within the reservoir low and promotes passive diffusion of naltrexone. The benefits of the product include complete medication adherence for one year after administration, fewer relapses, smooth profile ensuring complete prophylaxis without sub-therapeutic plasma troughs, full reversibility, and similar efficacy with less drug exposure. This technology has been validated clinically with another drug and tested preclinically with naltrexone. This project will finalize the chemistry manufacturing and controls, produce IND supplies, conduct an IND-enabling safety study, and submit the IND.

This study will examine the epidemiology of injection drug use, its infectious consequences, and service accessibility among young persons who inject drugs (PWID) in 15 rural counties in Maine, New Hampshire, and Vermont, then implement an integrated telemedicine approach to treat opioid use disorder (OUD) and reduce infections and overdose. The UG3 phase will characterize the risk environment and epidemiology of OUD, its infectious complications, opioid overdose, risk behaviors, service use, and needs in young PWID in these counties. An environmental assessment of policy and infrastructure will examine available services, needs, and gaps. The UH3 phase will evaluate the effectiveness of a regionalized integrated model of expanded service delivery for rural PWID. This project will provide in-depth understanding of high-risk rural PWID, inform community response strategies, and implement a comprehensive, integrated approach to treat OUD and reduce overdose and infectious complications among PWID in the rural United States.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) Data Coordinating Center (HDCC) will provide data management and oversight to all HBCD-NC sites to ensure the consortium’s primary objective of establishing a normative template of developmental trajectories over the first 10 years of life is met. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. The HDCC will coordinate data collection, data quality, data harmonization, data sharing, and data analysis efforts that are central to the consortium’s ability to implement a common research protocol. The HDCC will assemble all data across the consortium sites and distribute a comprehensive and well curated research dataset to the scientific community at large. The HDCC is tightly integrated with the HEALthy Brain and Child Development Administrative Core (HCAC) and includes a multi-institution investigative team at the University of Minnesota, University of California, San Diego, and Washington University at St Louis.
