Funded Projects

This project creates the HEAL Data2Action Data Infrastructure Support Center that will conduct research as well as support the HEAL Data2Action Innovation Projects with analytics and support for navigating electronic health records and other “big data” sources, as well as logistical processes related to privacy and ethics. The center will help plan for data collection and assessing outcomes, as well as provide data visualization efforts for various stakeholders. Key support mechanisms include courses, seminars, conferences, trainings, and on-demand technical assistance.

The IMPOWR (Integrative Management of Chronic Pain and OUD for Whole Recovery) Dissemination, Education, and Coordination Center (IDEA-CC) will develop infrastructure to amplify and create momentum for the findings of the IMPOWR initiative and other linked research networks. This center will i) rapidly deploy a communication framework to link IMPOWR clinical sites with each other and the larger HEAL research frameworks; ii) develop an educational infrastructure addressing stigma and health disparities in patients with co-morbid chronic pain and opioid misuse/disorder; iii) disseminate research findings effectively to targeted audiences; iv) develop a novel composite screening tool for chronic pain and opioid misuse/disorder; and v) harmonize processes for data collection and common data elements of chronic pain and opioid misuse/disorder measures across the IMPOWR research centers, providing a coordinated platform for gathering data from these studies. This center will rapidly disseminate key findings to stakeholders, clinicians, and patients to improve the health and wellbeing of individuals with co-occurring chronic pain and opioid misuse/disorder.

Chronic musculoskeletal pain is common and often severe enough to be disabling. Some treatments such as cognitive behavioral therapies or analgesics may relieve pain for some, but not all patients. Combining effective therapies and providing support to ensure that patients are motivated to adhere to their treatment may prove to be more beneficial to patients than prescribing a drug or recommending a single non-pharmacological treatment. This study aims to evaluate a combination of complementary treatments and Registered Nurse (RN) support to motivate patients to use and maintain combined therapies. Some patients will receive phone-based motivational interviews with an RN to enhance their adherence to pain coping skills learned through web-based cognitive behavioral therapy in combination with duloxetine, a pain-relieving drug. Others will receive both treatments but will not receive support from an RN. The study aims to determine whether motivational nursing support enhances adherence to newly learned pain coping skills, and results in improved pain relief and physical function.

Cancer remains a leading cause of death among Hispanic/Latino populations in the United States. Compared with non-Hispanic Whites, Hispanic/Latino cancer patients are more likely to experience poor quality of life and inadequate cancer-related care, including less effective pain relief and poor patient‒provider communication. Additionally, Hispanic/Latino populations often have inadequate access to pain treatment, due to both social disparities and language barriers. However, most behavioral and psychosocial oncology research continues to focus on non-Hispanic Whites, and empirically validated and effective treatment interventions, particularly psychosocial interventions, are often not available in Spanish. This project will generate a Spanish-language version of the painTRAINER internet-based coping skills training program that is both linguistically and culturally sensitive and will evaluate its feasibility and acceptability in Hispanic/Latino patients with persistent cancer-related pain.

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.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative model of developmental trajectories over the first 10 years of life. All sites in the HBCD-NC will carry out a common research protocol and will assemble and distribute a comprehensive research dataset to the scientific community. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. Most participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first 10 years of life.

Chronic pain diminishes the quality of life for millions of patients, and new drugs that have better efficacy and/or fewer side effects are needed. A promising target is the sphingosine-1-phosphate (S1P) receptor system, which mediates central nervous system (CNS) neuromodulatory functions. FTY720-phosphate, the active metabolite of FTY720 (FTY), acts as an agonist at four of the five S1P receptors (S1P1, 3, 4, 5). We propose that the S1P1 receptor is a target for treatment of neuropathic pain. We will test whether S1P1 receptors mediate anti-hyperalgesic effects in a mouse neuropathic pain model. The specific aims are to: 1) determine the role of S1P1Rs in alleviation of neuropathic pain by S1PR ligands; 2) determine the role of FTY-induced S1PR adaptation in FTY-mediated reversal of neuropathic pain; and 3) determine the role of S1P and S1P1 receptors in spinal glia in CCI-induced neuropathic pain and its reversal by FTY.

There is a need to develop a mu-opioid receptor (MOR) treatment with enhanced therapeutic effects and reduced undesirable effects. Recently, several highly selective and potent MOR modulators have been identified as novel leads for opioid use disorder treatment. They all showed more promising pharmacological profiles compared to other known drugs in this category. The current proposal will focus on further development of these leads for preclinical IND-enabling studies and dynamic drug discovery and development pipeline construction. This project plans to further validate therapeutic profiles of the current leads with self-administration and pharmacokinetic studies and expand the small-molecule library to build a dynamic drug discovery and development pipeline. Preclinical IND-enabling studies on the identified lead(s) will be conducted, and in vivo pharmacokinetics and pharmacodynamics profiles of the new hits will be compared with current leads to define the next generation of lead compound(s).

This U54 Center will use translational research from brain to bedside as a tool for medication development in cocaine use disorder. Preclinical and early phase I clinical PK/PD data will provide information for go/no-go decisions on phase II–III clinical trials with medications that show promise for cocaine use disorder. The overall goal of this research is to create a center that can provide important preclinical and early phase I clinical data to NIDA and pharmaceutical industry partners on novel compounds for cocaine use disorder. The aims related to the theme of the center will be achieved through two cores and three projects: The Administrative Core serves as a general resource for the other projects and the Educational Core, including oversight of fiscal and compliance matters, and will oversee interactions with outside entities, including NIDA and the pharmaceutical industry. The Educational Core will focus on training translational researchers for medication development for addictions across the two institutions.

Levo-alpha-acetylmethadol (LAAM) offers numerous behavioral and clinical advantages for select opioid use disorder (OUD) patients who do not respond to standard treatment. While LAAM was withdrawn from the market despite being approved for OUD treatment, this project seeks to develop novel, patentable, convenient dosage forms of LAAM, including novel LAAM oral dosage formulations and novel buccal film formulations of LAAM. Morphology, mechanical property, drug release kinetics, and stability of the oral dosage and buccal film formulations will be characterized to determine the instant release or steady release of LAAM, respectively. The two lead LAAM formulations with adequate release and stability profiles will be chosen through optimization studies both in vitro and in vivo. A human pharmacokinetic/pharmacodynamic study will then be carried out on the two selected formulations.

Evidence-based behavioral treatments for pain are among the most effective and safe approaches, but they are underused, especially among patients taking opioids long-term. Despite known risks to long-term opioid therapy (including opioid use disorder and overdoses), patients may be reluctant to try something different to manage their pain. This project brings together two evidence-based behavior change interventions—motivational interviewing and contingency management—into an online format. The research will test whether web-based tools or mobile apps influence a patient’s willingness to consider using non-medication treatments for pain. The research will assess feasibility, acceptability to patients and providers, and broad-scale implementation.

Nerve stimulators are devices surgically implanted near a peripheral nerve or on the spinal cord that use electrical signals to reduce the perception of pain. Although these devices can provide effective pain relief to patients, many have high complication rates, resulting from the wire moving, breaking, not working, or the implantable battery pack or permanent wire causing new pain. This project will support the development and animal testing of a peripheral nerve stimulator to treat chronic pain which can be implanted without surgery. Once injected, the device will provide pain relief through electrical stimulation and then be safely degraded and resorbed by the body.

This project aims to develop a next-generation noninvasive neuromodulation system for non-addictive pain treatments. The research team will build an integrated system that uses magnetic resonance image-guided focused ultrasound (MRgFUS) stimulation to target pain regions and circuits in the brain with high precision. The system will use MR imaging to locate three pain targets commonly used in clinical pain treatments, to stimulate those targets with ultrasound, and to monitor responses of nociceptive pain circuits using a functional MRI readout. Three collaborating laboratories will tackle the goals of this project: (Aim 1) Develop focused ultrasound technology for neuromodulation in humans, compatible with the high magnetic fields in an MRI scanner. (Aim 2) Develop MRI technology to find neuromodulation targets, compatible with focused ultrasound transducers. (Aim 3) Validate the complete MRgFUS neuromodulation system in brain pain regions in nonhuman primates. By the end of the project, the research team will have a fully developed and validated MRgFUS system that is ready for pilot clinical trials in pain management.
