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.

More than 700,000 total knee replacement surgeries are performed each year in the United States to relieve joint pain in patients with end-stage osteoarthritis or rheumatic arthritis. However, many patients still experience significant pain after this procedure, calling for additional long-lasting, drug-free pain management strategies. This project will develop and test a commercial prototype device for persistent knee pain after total knee replacement. The injection-based method freezes peripheral nerves to reduce pain sensation.

This project will develop and refine a wearable device (forearm bracelet) designed to rapidly sense and report the presence of opioids in the wearer. This research will optimize this device to provide ultra-high sensitivity, enhanced drug specificity, long-term durability, low power consumption, and cost-effective production. The findings could support a path toward commercialization of this new device.

The primary cause of death associated with opioids is opioid-induced respiratory depression, and there is currently no way to prevent this condition. The goal of this research is to develop a therapy to prevent opioid-induced respiratory depression without disrupting opioids’ analgesic effects. Previous research has shown that the hormone leptin, which suppresses appetite and increases metabolic rate, also stimulates breathing. This research project in a mouse model will test if the novel, brain-penetrant leptin receptor-binding protein E1/Aca can prevent fentanyl-induced breathing failure without diminishing fentanyl’s analgesic effects.

Lumbar spinal surgery, an increasingly common surgery in adults with severe chronic back pain, is associated with acute post-surgical pain, costly postoperative opioid-related adverse effects, long hospital stays, high-risk for chronic post-surgical back pain, and persistent opioid use and dependence. Each individual responds differently to opioids based on their unique genetic and clinical factors, and the current trial-and-error approach to opioid use and prescribing promotes excessive opioid use, costly adverse outcomes, and poor surgical pain management. To address this issue, this research project will develop a preoperative diagnostic test that will use genetic and clinical information to proactively assess each person’s risk for opioid-related adverse events and chronic post-operative pain. The results will help clinicians provide personalized pain management to maximize pain relief while minimizing opioid-related safety risks, including opioid dependence.

Relapse is common in people with opioid use disorder, and recovery attempts often fail within 6 months. This research project will test a novel virtual reality intervention to improve recovery outcomes for people recovering from opioid use disorder. By increasing future orientation and delay-of-reward behavior with a precision medicine personalized experience, the intervention is designed to enhance advantageous decision-making and increase positive future outcomes. The results of this study will provide critical data for creating a commercially viable software product for facilitating relapse prevention and improving opioid use disorder recovery outcomes.

About 14% of U.S. adults report experiencing migraine symptoms within any given 3-month period, making it the second most disabling illness in the world. Nonspecific pain medications used in migraine (e.g., acetaminophen, nonsteroidal inflammatory drugs, opioids) are often not effective for severe migraine symptoms or cause significant adverse effects. A research team of migraine care specialists, device and drug developers, and clinical research specialists has created a technology for accurately delivering self-administered migraine medication to the upper nasal cavity. The technology enables development of a self-administered therapy to provide rapid pain relief without harsh and addictive side effects of existing migraine medications. This project will establish efficacy and evaluate commercial design feasibility for this treatment.

Infants exposed to opioids in the womb may suffer from neonatal opioid withdrawal syndrome (NOWS). They experience symptoms such as excessive crying, irritability, rapid breathing, elevated heart rates, tremors, and sometimes seizures. There is no accepted standard treatment for NOWS; infants are treated with pharmacological (opioid administration and gradual weaning) and nonpharmacological measures. Nonpharmacological care such as swaddling, rocking, frequent feedings, and skin contact, are time consuming, placing a substantial burden on hospitals with limited resources. Prapela, Inc. previously developed a hospital bassinette pad that, using stochastic vibrotactile stimulation (SVS) technology, very gently rocks infants with NOWS to reduce irritability and other symptoms without disturbing sleep patterns. This project will conduct an additional clinical study to determine the SVS bassinette pad’s efficacy in reducing breathing and heart rate, its safety, and its acceptability with clinical staff and parents caring for infants with NOWS.

Neuropathic pain adversely affects quality of life and remains challenging to treat, presenting high unmet medical need. One example of this type of pain, chemotherapy-induced peripheral neuropathy, is a chronic, severely debilitating consequence of cancer therapy for which there are no effective treatment strategies. This research is testing a new cannabidiol (CBD) analogue (KLS-13019) with neuroprotective properties and which has improved drug-like properties compared to CBD. This project will optimize the process to manufacture KLS-13019, develop analytical methods, optimize its formulation, evaluate its safety and toxicity, and test KLS-13019’s efficacy of in a rat model of chemotherapy-induced peripheral neuropathy.

Chronic pain is a major healthcare burden. However, the types and underlying mechanisms of pain vary greatly, as do patient responses to currently available pain medications. Inflammation in the nervous system (neuroinflammation) is involved in several types of pain, and targeting key molecules involved in neuroinflammation is therefore a promising treatment approach. The chemokine receptor system, a complex network of more than 20 different receptors and more than 80 molecules that bind to these receptors, has a central role in neuroinflammation. Researchers do not yet fully understand the functioning of this network and how specific receptors vary in different chronic pain conditions. Therefore, this project aims to further characterize the expression of one specific receptor, using samples collected from participants in clinical trials evaluating a compound that interferes with the receptor’s function. This information should allow researchers to classify pain patients and identify those most likely to benefit from a treatment with compounds targeting the receptor.

There is an urgent need for non-opioid post-operative pain management solutions.  This research is developing a naturally absorbable polymer film that can release controlled amounts of the non-opioid analgesic bupivacaine – aiming to manage pain for several days following surgery. Project objectives are to optimize the timing of drug release, develop manufacturing standards, determine effective dosage for preserving motor function, and determine safety and efficacy in mouse models of neuropathic pain. Continued development of this film delivery system may lead to a new, non-opioid therapeutic strategy that could be combined with local anesthesia for up to 4 days after surgery to reduce or potentially eliminate opioids use.

As prescription opioid drug abuse and overdose-related deaths continue to skyrocket in the United States, the need for new and more effective non-addictive pain drugs to treat chronic pain remains critical. This research is conducting studies in animal models of a small molecule that has high potential to treat chronic pain conditions associated with neuropathy and/or inflammation. The goal of this project is to conduct dosing and other studies leading up to an animal model study of the potential drug in a toxicology study for 28 days. Results may lead to Investigative New Drug regulatory clearance to begin clinical studies to validate the potential drug’s efficacy and safety.
