Funded Projects

Neonatal Opioid Withdrawal Syndrome (NOWS) is a condition that occurs when newborns are exposed to opioids during pregnancy. Symptoms often include tremors, excessive crying, sleep deprivation, and swallowing difficulties. Cases are rising, with a newborn affected by NOWS approximately every 15 minutes. Currently, healthcare providers in the United States lack standard, evidence-based treatments for NOWS. 

This project is part of a multi-center, randomized controlled clinical trial that directly compares NOWS treatments—morphine, methadone, and buprenorphine—and takes into account other types of non-drug therapies, such as behavioral interventions. The goal is to generate results that can inform clinical practice guidelines and give newborns with NOWS the best start possible. 

New Mexico is an epicenter of the opioid epidemic with high rates of maternal opioid use disorder and NOWS. This site has expertise in multi-center clinical trials for newborns, a history of high rates of study recruitment and follow-up, and a diverse population that includes Latinx and Native American women. The hospital currently cares for infants with NOWS in a variety of settings, including rooming in, a nursery, and a neonatal intensive care unit.

Patients with severe, intractable chronic pain primarily receive treatment with opioids, and non-opioid treatment options are urgently needed. These patients may be candidates for treatment using other types of pain medications administered via intrathecal injection—that is, injection directly into the fluid-filled space between the membranes surrounding the brain and spinal cord. Intrathecal injection requires much lower medication doses than systemic administration. Centrexion Therapeutics Corporation seeks to develop CNTX-3100, a highly selective and highly potent novel small molecule that activates the nociception receptor (NOPr), for intrathecal administration using a pump approved by the U.S. Food and Drug Administration. In animal studies, such NOPr agonists had powerful analgesic effects when delivered directly to the spinal cord by intrathecal administration. CNTX-3100 has ideal properties for intrathecal delivery and in animal studies provided pain relief and a safety profile that was superior to intrathecally administered morphine. This project will scale up the drug, develop a formulation that ensures a stable product for intrathecal delivery, and conduct preclinical toxicity studies to prepare for a Phase 1 clinical trial.

Substance use disorder (SUD) is a serious public health and socioeconomic burden. In this project, researchers will develop novel drug compounds that dually target orexin receptors and kappa opioid receptors, which have both been implicated in SUD. The compounds will then be tested for effectiveness in preclinical models of SUD, including models of cocaine, methamphetamine, and fentanyl use. This research has the potential to provide highly impactful and innovative treatment options for SUD via simultaneous modulation of multiple signaling pathways.

This site includes newborn nurseries and intensive care nurseries at 4 large
maternity centers across the Children’s Hospital of Philadelphia (CHOP) Newborn Care Network, each with a dedicated follow-up clinic, ensuring access to a large and diverse patient population for long-term study. CHOP also has a long history of successfully conducting multi-center clinical studies.

Efforts to identify non-opioid analgesics for treatment of chronic pain have identified a protein, carbonic anhydrase-8 (CA8), in pain-sensing nerve cells in the spinal cord (dorsal root ganglion cells) whose expression regulates analgesic responses. Gene therapy delivering CA8 to dorsal root ganglion cells through clinically relevant routes of administration functions as a “local anesthetic” that induces long-lasting pain relief in animal models of chronic pain. This project will further develop CA8 gene therapy with the goal of treating chronic knee osteoarthritis pain. It will assess several gene therapy constructs to determine the doses needed, safety, efficacy, and specificity to nerve cells for each construct. It will then select the safest and most effective construct that can be administered via the least invasive route for further development. The project will include all steps necessary to identify one candidate gene therapy construct that will be suitable to begin clinical trials in patients with chronic knee osteoarthritis pain.

Effective medications for opioid use disorder (MOUD) are approved by the Food and Drug Administration for the treatment of people with opioid use disorder; however, only a small fraction of patients who would benefit from these medications actually use them. Several reasons contribute to low MOUD use, including lack of insurance; lack of knowledge about the medications, both among patients and providers; stigma associated with MOUD; and social norms. Innovative methods are needed to help increase MOUD use. One such option is peer-led interventions that might increase patients’ interest in MOUD. One existing peer-led intervention is the Harnessing Online Peer Education (HOPE) online community intervention that has been designed to reduce stigma and increase health behavior change among stigmatized populations, such as people living with HIV. This project will investigate whether and how HOPE can be adapted for people with opioid use disorder. It will assess whether HOPE can effectively increase MOUD requests, MOUD uptake, and sustained adherence to MOUD as well as reduce overdose rates.  

Prescription opioids provide pain relief, but overdose can be fatal because opioids also depress breathing through opioid-induced persistent apnea, when breathing stops. This research will determine whether targeted activation of a specific, opioid-insensitive brain region that triggers exhalation can increase tolerance to fentanyl-induced apnea. The research also seeks to identify the receptors responsible for this exhalation, which could be targets for new medications that prevent the negative impact of opioids on breathing. This research lays the groundwork for more preclinical and translational studies to prevent opioid-induced persistent apnea. 

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.

Chronic pain affects millions of Americans and remains poorly understood and challenging to manage. Researchers do not fully understand brain processes involved in chronic pain, which can vary considerably from person to person. This project will analyze brain function using magnetic resonance imaging (MRI) in individuals with and without chronic pain. The research will also directly determine the degree of pain-related brain imaging changes by using a large database of brain imaging data.

Clinical decision support tools help clinicians make treatment decisions based on routinely collected data and offer a promising strategy to implement evidence-based practices for safe and effective pain management. This project will use clinical decision support tools embedded into electronic health records to help healthcare providers make treatment decisions that align with opioid prescribing guidelines from the Centers for Disease Control and Prevention (CDC). The project will also use information from prescription drug monitoring programs, insurance claims, and mortality data to evaluate patient outcomes. This research will evaluate how prescribing practices that align with CDC guidelines affect patient outcomes and whether clinical decision support tools provide an advantage over standard care practices for pain management.

Withdrawal symptoms associated with current opioid use disorder treatments, such as naltrexone or buprenorphine, can be serious obstacles to successful treatment. This project aims to develop a U.S. Food and Drug Administration-approved sedative medication (dexmedetomidine) as an under-the-tongue film to treat opioid withdrawal symptoms at doses that have minimal ill effects on blood pressure and heart rate. This research will compare the safety and efficacy of dexmedetomidine to lofexidine, which is currently approved to treat opioid withdrawal.
