Funded Projects

The opioid epidemic has increased the demand for a research workforce with the necessary expertise and skills to conceptualize and carry out studies to expand and improve treatment options for opioid use disorders (OUDs). In particular, as the NIDA-funded Clinical Trials Network (CTN) expands the number of nodes and takes on additional studies as part of the HEAL Initiative, the need for an increasing number of staff who are familiar with the CTN research environment is amplified, and opportunities to provide a platform for training new investigators interested in the OUD area are increased. The CTN Research workforce development and dissemination program will provide multi-modal training, including didactic, experiential, and mentoring, to prepare research staff (regulatory personnel, study coordinators, project managers), post-doctoral fellows and faculty from a variety of disciplines (MD, PhD, PharmD, Nurse Practitioners, etc.) to participate in HEAL Initiative studies being conducted within the CTN.

The growing opioid use epidemic in the U.S. has been associated with a significant increase in the prevalence of pregnant opioid-dependent women and neonatal abstinence syndrome, which is associated with adverse health effects for the infant and with costly hospitalizations. Maintenance with sublingual (SL) buprenorphine (BUP) is efficacious for opioid use disorder but has disadvantages that may be heightened in pregnant women, including the potential for poor adherence, treatment dropout, and negative maternal/fetal effects associated with daily BUP peak-trough cycles. Extended release (XR) formulations may address some of these disadvantages. The primary objective of CTN-0080 is to evaluate the impact of treating opioid use disorder in pregnant women (n = 300) with BUP-XR, compared to BUP-SL, on maternal-infant outcomes. Other objectives include testing a conceptual model of the mechanisms by which BUP-XR may improve maternal-infant outcomes, relative to BUP-SL; determining the economic value of BUP-XR, compared with BUP-SL, to treat OUD in pregnant women; and evaluating the impact of BUP-XR, relative to BUP-SL, on neurodevelopment when the infant/child is approximately 12 and 24 months of age. Ultimately, this study will help in increasing access to treatment as well as provide quality care for pregnant/postpartum women.

Every year, more than 330,000 Americans are hospitalized for hip fractures. Rapid surgical intervention and pain treatment is critical to recover mobility and reduce other health complications. Ultrasound-guided regional anesthesia techniques are an effective alternative to opioid medication, but require specialized training for use in the emergency department. This project will develop and validate an easy-to-use ultrasound-based regional anesthesia guidance system, to ultimately improve access to non-opioid-pain treatment for hip fracture pain.

Head and neck cancer is particularly susceptible to nociceptive and neuropathic pains because it is dense with sensitive anatomic structures and richly innervated. Transcranial magnetic resonance imaging–guided focused ultrasound (FUS) is a new stereotactic modality capable of delivering high-intensity energy through the intact human skull with submillimeter precision. This clinical trial will target the spinothalamic and spinoreticular pain circuits by unilateral FUS mesencephalotomy, an effective procedure for cancer pain but limited by the accuracy of its era. The primary aim is to assess the safety and preliminary effectiveness in six head and neck cancer patients with opioid-resistant pain. Researchers will investigate the potential mechanism of pain relief as the mesencephalotomy target involves the confluence of the ascending and descending pain systems. Aims 2 and 3 will investigate these systems with electrophysiology specific for the spinothalamic tract and carfentenil positron emission tomography imaging that measures the brain’s endogenous opioids.

Sickle cell disease is an inherited blood disorder affecting about 100,000 Americans and over 20 million people worldwide. It is caused by a mutation in the gene for beta-globin that results in the characteristic sickled shape of red blood cells, life-long severe pain, and shortened lifespan. Painful episodes that require hospitalization and, in many cases, opioid treatment, are a hallmark of sickle cell disease. The source of these painful episodes remains unclear, and it is also unknown why pain severity varies so much among affected individuals. This project will identify novel, non-opioid targets to reduce sickle cell-related pain and search for biomarkers to help clinicians predict which individuals are at risk for increased pain, thereby improving health outcomes for people with sickle cell disease.

Many opioid harm reduction services are designed and implemented to serve urban populations in traditional centers of opioid use and leave rural patients underserved. The proposed project seeks to demonstrate improved MAT participation, naloxone distribution, and syringe support services (SSPs) among justice-involved persons with opioid use disorders, and thus improve health and criminal justice outcomes across diverse urban and rural settings in Illinois. Reducing Opioid Mortality in Illinois (ROMI) is a multi-site trial that will be carried out using a hub-and-spoke model, with centralized long-standing social services infrastructure at the Community Outreach Intervention Projects (COIP) hosted at the University of Illinois at Chicago. COIP provides case management/transition of care services to justice-involved opioid users, extending resources and technical assistance to less-populated rural areas hardest hit by the opioid epidemic.

Over-the-counter medicines such as non-steroidal anti-inflammatory drugs are ineffective for treating severe chronic pain and may have serious side effects from continued use, which limits treatment options. A kinase (an enzyme whose activity targets a specific molecule) called TAK1 is involved in the chronic pain process. This research will develop a molecule previously shown to be effective in a model of inflammatory pain that also inhibits TAK1. A main goal will be to determine if this inhibitor (takinib analog HS-276) can cross the blood-brain barrier and, if successful, pursue FDA  Investigative New Drug-enabling safety studies leading to a Phase I clinical trial and a potential new chronic pain treatment.

Health services for the treatment of opioid use disorder (OUD) are fragmented in west Chicago, an epicenter for overdose deaths. This project will develop a data-driven opioid response plan involving key partners. These include local health departments, community organizations, health care systems, and people with lived experience. The research will develop a digital screening tool for OUD that can be used in hospitals and their emergency departments. The tool will be built from machine learning of data from electronic health records, the prescription drug monitoring program, and patient-reported measures. The research will test the value of the screening tool for connecting people to treatment and preventing fatal overdoses mortality in local neighborhoods.

The HEAL Initiative is establishing a HEAL Data Ecosystem to help investigators manage and share HEAL-generated data, and quickly and efficiently disseminate HEAL results broadly to stakeholders. The HEAL Platform, built by the University of Chicago, will enable broad sharing of HEAL data by linking data stored in various locations, annotated and curated to various extents, to one central interface where studies, data, and digital assets can be discovered and accessed via metadata query. The Platform will also provide secure workspaces so that under appropriate conditions, data can be pulled from disparate repositories and computed on in the same cloud space, using tools and analytic suites provided within. The Platform team will collaborate closely with the HEAL Data Stewardship Group (Renascence Computing Institute at the University of North Carolina Chapel Hill and RTI, International) to meet the needs and goals of the HEAL Data Ecosystem.

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.

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.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative template 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. The Northwestern University study site is in Chicago where rates of prenatal substance use are rising and consistent with the national trend. This site will recruit a diverse urban sample of mother-infant pairs reflecting the population of Chicago.
