With the entwined crises of opioid use and chronic pain, there is a need for alternative, safe therapies to manage opioid use disorder, opioid withdrawal symptoms, chronic pain, and/or associated anxiety and depression. A proof-of-concept preclinical study has already been conducted of a cannabinoid-opioid combination that demonstrated opioid-sparing and synergistic analgesic effects, with the combination providing greater analgesia in a rodent model of chronic pain than a standard dose of the opioid alone. This proposal aims to develop a fixed-dose combination (FDC) of the cannabinoid-opioid that may have improved analgesia with lower opioid doses and thereby lower the risk of dependence, withdrawal, diversion, abuse, and overdose. Preclinical pharmacokinetic and ?in vivo ?safety studies will help determine if co-administration alters the pharmacokinetics and/or respiratory depression related to either compound in rodents.

Many current pain relief treatments rely on use of opioid drugs. This research is conducting preclinical development on a non-addictive, non-opioid therapeutic that uses antibodies to target the sodium channel Nav1.7. This channel is known to be one of the primary routes for generating pain signals – thus it is a target for reducing pain. The antibody approach offers potential for greater specificity than small molecule approaches, potentially resulting in fewer side effects.

Although medications for opioid use disorder are effective and available, providers currently lack methods to monitor patients and thus inform improved dosing. This project will develop Strength Band Platform, an innovative artificial intelligence-based digital platform. The wearable device will collect patient physiological characteristics to detect relapse and withdrawal during treatment with medications for opioid use disorder in real-world settings. 

Most people with opioid use disorder are either not in treatment or receive inconsistent treatment. Peer support is proven to be effective at engaging patients who are unwilling or unable to seek traditional treatment, but commonly available group support models are often separate from other clinical care or are otherwise hard for patients to access. This research will test a novel, machine learning enabled, digital peer support program added to an anonymous text-based social network that can provide 24/7 support for patients at all stages of recovery. The project will examine the ability of this digital service to engage and retain patients with opioid use disorder and will also develop novel techniques to automatically analyze patient messages for clinical and social determinants of health-related needs.

Migraines and other headaches are often debilitating for patients, yet few treatment options providing sustained relief exist. All available therapies, including frequently prescribed opioids, have considerable side effects or limitations. Therefore, novel treatment approaches are needed to reduce or eliminate the need to use opiates and other systemic pharmaceuticals. Thermaquil Inc. has developed a new way of stopping migraine and other headache pain by noninvasively blocking pain signal transmission in the head, which in initial studies allowed patients to discontinue use of opioids and other addictive pain medications. Thermaquil will now be conducting a larger randomized controlled trial to demonstrate the safety and effectiveness of this novel approach. After a baseline period, patients will be randomly assigned to the active or control condition and receive a single treatment. The study will continue for 12 weeks with the active versus control arms, before all patients will be given active therapy for an additional 12 weeks.

 Non-Invasive Brain Stimulation (NIBS) has been successfully applied for the treatment of chronic pain (CP) in some disease states, where treatment induced changes in brain activity revert maladaptive plasticity associated with the perception/sensation of CP [25-28]. However, the most common NIBS methods, e.g., transcranial direct current stimulation, have shown limited, if any, efficacy in treating neuropathic pain. It has been postulated that limitations in conventional NIBS techniques’ focality, penetration, and targeting control limit their therapeutic efficacy . Electrosonic Stimulation (ESStim™) is an improved NIBS modality that overcomes the limitations of other technologies by combining independently controlled electromagnetic and ultrasonic fields to focus and boost stimulation currents via tuned electromechanical coupling in neural tissue . This proposal is focused on evaluating whether our noninvasive ESStim system can effectively treat CP in carpal tunnel syndrome (CTS), both as a lone treatment and in conjunction with physical therapy (PT). Investigators hypothesize ESStim can be provided synergistically with PT, as both can encourage plasticity-dependent changes which could maximally improve a CTS patient’s pain free mobility. In parallel with the CTS treatments, the team will build multivariate linear and generalized linear regression models to predict the CTS patient outcomes related to pain, physical function, and psychosocial assessments as a function of baseline disease characteristics. The computational work will be used to develop an optimized CTS ESStim dosing model. 

New and safe therapeutic targets for treating opioid use disorder are needed. One promising approach is to test drugs currently approved by the U.S. Food and Drug Administration that work independently of the body’s opioid system. The medication memantine targets N-methyl-D-aspartate (NMDA) receptors in the brain, which have been implicated in the development and maintenance of addiction. This project will study a miniature version of multiple memantine molecules bound together that attaches only to NMDA receptors that are not within nerve connections. The research will evaluate the safety, misuse potential, and effectiveness of this molecular assembly in preclinical models. 

Effective medication-based treatment could prevent overdose deaths and help individuals recover from opioid use disorder, but only a fraction of those in need access treatment or receive a medication approved by the U.S. Food and Drug Administration. One way to improve people’s choice to seek and stay in treatment is to improve training for addiction treatment counselors beyond current methods that rely on brief online or in-person workshops. The goal of this research project is to develop and evaluate the technical feasibility and commercial viability of a scalable digital program to train behavioral addiction professionals in Community Reinforcement and Family Training (CRAFT), an evidence-based approach to increase treatment entry, using ongoing counselor training with feedback and coaching.

While patient self-report of pain is the gold standard of pain measurement, this may not be feasible in critically ill patients who are sedated and intubated, unconscious, or unable to verbally communicate. Pupillary dilation (PD) is a reliable indicator of acute pain, and measurement of pupil size changes may be useful in determining the intensity of pain experienced as well as the efficacy of an analgesia. Research also demonstrates that pupillary unrest under ambient light (PUAL) is an objective marker of sensitivity to opioids, and facial expression analysis can help detect pain. Benten Technologies, Inc. aims to develop and validate IMPACT, a device that uses pupillometry with a proprietary algorithm to measure both PD and PUAL and conduct facial expression analysis using computer vision. The project team will then demonstrate the feasibility of IMPACT in helping clinicians objectively determine pain and assess opioid efficacy and compare results obtained to pain scores reported by patients.

Thoracic (chest) surgeries often cause both short-term (acute) and long-term (chronic) pain and long-term opioid use. Unique genetic and clinical risk factors affect individual responses to surgical pain and pain medications. Current trial-and-error approaches to managing post-surgical pain and opioid prescribing are not ideal. This project will develop predictive software within a medical device that takes into account an individual’s genetic and clinical information to predict the likelihood of chronic pain following thoracic surgery. 

 Investigating the broader efficacy of sEH inhibition and specifically our IND candidate, EC5026, has indicated that it is efficacious against chemotherapy induced peripheral neuropathy (CIPN). This painful neuropathy develops from chemotherapy treatment, is notoriously difficult to treat, and can lead to discontinuation of life-prolonging cancer treatments. Thus, new therapeutic approaches are urgently needed. The research team will investigate if EC5026 has potential drug-drug interaction with approved chemotherapeutics or alters immune cells function, and assess the effects of sEHI on the lipid metabolome and probe for changes in endoplasmic reticulum stress and axonal outgrowth in neurons. The team proposes to more fully characterize the analgesic potential of our compound and investigate on and off target actions in CIPN models and model systems relevant to cancer therapy.

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.

There is a need for safe, effective, well- tolerated drugs to treat painful neuropathy by halting or reversing the underlying pathology of the disease. One promising approach to treating painful neuropathy without opioids is the use of ghrelin, a 28-amino acid acylated peptide hormone. However, it has a short half-life and must be delivered via a constant intravenous infusion to have a therapeutic effect. Extend Biosciences' D-VITylation platform technology is truly enabling for small peptide-based therapeutics that are rapidly cleared from the bloodstream by renal filtration. The platform harnesses the naturally long half-life of vitamin D and its dedicated binding protein, VDBP. When the vitamin D molecule is conjugated to a biological therapeutic, it dramatically improves the half-life and bioavailability of the drug. Use of the technology should also allow the drug to be self-administered by subcutaneous injection. This would be of significant benefit to patients. In this project, the team will test the efficacy of EXT405 in a cell-based model of neuropathy as well as in animal models of CIPN and diabetes- induced neuropathy.
