Funded Projects

The Greater New York Clinical Center (GNYCC) aims to engage experts in pain research and pain practice to build the infrastructure required to support the objectives of the Early Phase Pain Investigation Clinical Network (EPPIC-Net). The GNYCC will provide expertise and resources to perform phase 2 clinical trials to test the efficacy of novel pain treatments, as well as phenotyping and biomarker studies that will enable customized treatments. The consortium comprises four major academic centers in New York City, one of the most diverse cities in the United States and the nation’s largest metropolitan area. We will 1) build infrastructure to rapidly access clinical trial resources and a network of investigators and clinical leaders, 2) develop a plan for swift evaluation and launch of proposed studies, and 3) optimize patient retention and monitor sites to ensure protocol adherence, data quality, and efficiency.

Temporomandibular joint (TMJ) disorders are the most common form of chronic pain in the face and mouth area (orofacial pain), but relatively little is known about the biological causes of these conditions. This project will define the properties of sensory neurons that connect to tissues that make up the TMJ which connects the lower jaw and skull. This research aims to lay groundwork for development of new therapeutic approaches to treat these painful conditions.

In the US, approximately 100,000 people, mainly of African and Hispanic background have Sickle Cell Disease (SCD). Pain is a constant companion and chronic disabling symptom for those with SCD. It is increasingly clear that adults with chronic SCD pain also experience periods of acute worsening of their pain. The evaluation of nonpharmacological therapies that reduce chronic pain and the need for opioid medication among individuals with SCD is critically needed to address lack of adequate pain control to prevent periods of acute deterioration and high opioid use with negative sequelae. The investigators will conduct a hybrid type 1 effectiveness-implementation trial to assess the effectiveness of acupuncture and guided relaxation in patients with SCD while observing and gathering information on implementation in three health systems. The study will utilize a 3-arm, 3-site pragmatic randomized controlled SMART trial design that evaluates adaptive interventions, in which selection of interventions responds to patients? characteristics and evolving clinical status. The investigators will use the Consolidated Framework for Implementation Research to plan, execute, and evaluate implementation processes.

Throughout clinical pain research, there is a need to increase the workforce of researchers familiar with individualized treatment strategies known as precision pain medicine. This mentoring award will leverage EPPIC-Net’s Clinical Coordinating Center resources to encourage interest in clinical pain management, in particular through multidisciplinary pain research projects. A selected clinician-researcher  will mentor early career investigators and provide them with hands-on training activities and other skill-building experiences in clinical pain research, with a focus on precision pain medicine, biomarker development, and pain assessment. Mentoring activities will include formal educational coursework, inclusion in EPPIC-Net working groups, and collaborative writing experiences.

Back pain, including low back and neck pain, is one of the most prevalent and disabling pain disorders. Treatment requires ongoing self-management, but most healthcare systems do not support self-care and instead focus on costly, provider-dependent therapies that remain inaccessible to many Black and Hispanic Americans and individuals with less education and income. This project will address these health disparities by developing a personalized self-management treatment program that includes pain education, mindfulness, cognitive behavioral therapy, and exercise – and make it available in community settings.

EPPIC-Net will provide a robust and readily accessible infrastructure for the rapid implementation and performance of high-quality comprehensive studies of patients with well-defined pain conditions, and the rapid design and performance of high-quality Phase 2 clinical trials to test promising novel therapeutics for pain. Using the Hospital of the University of Pennsylvania as a hub and five additional centers that are part of the UPenn Health System and the Children’s Hospital of Philadelphia (CHOP) as spokes, studies will be conducted as designed by the expertise of the EPPIC Network, which intends to bring intense focus to relatively small numbers of patients with clinically well-defined pain conditions and high unmet therapeutic needs. The UPenn Specialized Clinical Center (SCC) will test novel, efficient study designs including adaptive and platform designs, validation studies of biomarkers, and biomarker-informed proof of principle or target engagement studies in Phase 2 trials of interventions from academic and industry partners.

The objective of the Early Phase Pain Investigation Clinical Network (EPPIC-Net) and EPPIC- Net initiatives is to rapidly and efficiently translate advances in the neurobiology of pain into treatments for people with chronic and acute pain, conditions associated with a significant burden to both patients and society. The Clinical Coordinating Center (CCC) for EPPIC-Net will promote and facilitate, from initial conception through final analysis, clinical trials in adult and pediatric populations with acute or chronic pain by providing efficient methodological, organizational, and logistical support. The EPPIC-Net-CCC will adopt and establish processes aimed at dramatically increasing the efficiency of multicenter clinical trials, improving the overall quality of clinical trials, promoting patient recruitment and retention as well as increasing the number of clinical investigators and research staff well trained and passionate about leading and conducting multicenter clinical trials.

This project will examine the association between end plate pathology and chronic low back pain (cLBP) and improve patient selection by developing and translating new imaging tools, technologies, and/or methods (iTTM) that provide accurate, noninvasive measures of end plate pathologies. A search for clinically relevant biomarkers of end plate pathology will focus on novel imaging measures of end plate bone marrow lesion (BML) severity with IDEAL MRI and cartilage endplate (CEP) fibrosis/damage with UTE MRI, assess interactions with paraspinal muscles, and identify metrics that associate with pain, disability, and degeneration. The research will refine imaging and post-processing methodologies by leveraging and expanding existing cross-sectional cohorts and then deploy and validate the new end plate iTTM to other BACPAC sites to test the most promising metrics’ clinical utility. These studies will provide validated iTTM that are useful for addressing the end plates pathology’s role in cLBP, identifying sub-phenotypes, discovering pain mechanisms, uncovering treatment targets, and selecting patients.

It is increasingly clear that the microbiome influences psychoneurological symptoms, including pain. This project will support clinical research training focused on examining the relationship between the composition and function of the gut microbiome, including the symbiotic bacteria residing in the gut and their functional gene content, and chronic pain among adults with end-stage kidney disease (ESKD). It provides an opportunity for the trainee to expand his skill set as a pain investigator, through experience in implementing and evaluating pain management interventions in adults with ESKD and chronic pain receiving maintenance hemodialysis. The project aims to determine the acceptability of collecting feces and the feasibility of fecal data collection procedure to determine the best strategies for recruiting research participants from multiple dialysis facilities. These steps will allow the exploration of gene content of the gut microbiota and short-chain fatty acids among people with ESKD on maintenance hemodialysis before and after pain management interventions.

Back pain is the most common chronic pain diagnosis and the most common diagnosis for which opioids are prescribed. Clinical practice guidelines make it clear that nonpharmacologic treatments are preferable to opioids for patients with back pain. Despite clear evidence, over-prescribing of opioids to individuals with back pain continues. Providers of nonpharmacologic care are often absent or unreachable from rural and low-income communities and patients with limited financial resources. Many rural and low-income communities are served by Federally Qualified Health Centers (FQHCs) that are at the forefront of the opioid crisis, but often lack adequate options to provide accessible nonpharmacologic treatments. This pragmatic clinical trial will compare the effectiveness of different telehealth strategies to provide effective nonpharmacologic interventions to overcome the barriers specific to serving rural and low-income communities. The trial will evaluate two strategies, one providing both a brief pain teleconsult with phone-based physical therapy, the other uses an adaptive strategy ? providing the brief pain teleconsult first, followed by phone-based physical therapy to those who need additional treatment. The study will also evaluate outcomes related to the efforts to implement strategies in FQHC clinics. This research will provide a toolkit for future efforts to make nonpharmacological interventions for back pain available in other low resource health care settings.

Some chemotherapy treatments damage nerves outside the brain and spinal cord. This condition, chemotherapy-induced peripheral neuropathy, involves tingling, burning, weakness, or numbness in hands and/or feet and affects nearly 70% of cancer patients receiving chemotherapy. Common pain medications, including opioids, can relieve pain for short intervals but are not suitable for long-term therapy. This project will develop and test a new type of treatment (reduced size cyclic analogs) for this condition. The research will evaluate the ability of this therapy to reduce inflammation and pain, as well as to repair nerve damage.

Enhancing the workforce of pain investigators and practitioners is a key goal of the NIH HEAL Initiative. This mentoring award leverages the resources at one of EPPIC-Net’s Specialized Clinical Centers to encourage interest in clinical pain management, in particular through multidisciplinary pain research projects. A selected investigator will train early career clinical researchers on how to develop and validate relevant pain measures and outcomes in chronic pain conditions, including chemotherapy-induced peripheral neuropathy and neuropathic chronic low back pain. Mentoring activities will include formal research and analysis, active inclusion in EPPIC-Net working groups, and collaborative writing experiences.

The research team developed an in vitro multi-component joint on a chip (microJoint), in which engineered osteochondral complexes, synovium, and adipose tissues were integrated. This study will introduce sensory innervation into the microJoint and a neuron-containing microfluidic ally will be developed to innervate the microJoint. The osteoarthritis (OA) model will be created in the Neu-microJoint system. The research team will assess activation and/or sensitization of nociceptive afferents with electrophysiology, as well as neurite outgrowth. They will mechanically insult the Neu-microJoint and assess the emergence of “pain” in response to prolonged mechanical stress. Researchers will assess the impact of drugs used clinically for management of OA on OA models and will then use “omic” approaches to identify new biomarkers and therapeutic targets. Researchers will assess the impact of opioids—which they hypothesize will increase the rate of joint degeneration and potentiate the release of pain-producing mediators—on neural activity in the presence and absence of joint injury, as well as the integrity of all joint elements.
