There are alarming rates of substance abuse and diversion in hospitals, with multiple studies finding that roughly 10% of our nation’s nurses, anesthesiologists, and pharmacists are currently diverting drugs in their workplaces. Diversion continues even though most hospitals already lock addictive drugs in Automated Dispensing Machines (ADMs) and run monthly “anomalous usage” computer reports to try to detect diversion. This SBIR project will research mechanisms to detect when health care workers (HCWs) in hospitals steal or “divert” legal drugs, either to abuse themselves or to illegally sell to others, by building a computer system with (a) automated data feeds from multiple existing hospital computer systems and (b) advanced analytics to flag potential diversion for investigation. This research has the potential to reduce injuries to HCWs who are becoming addicted, destroying their careers, jeopardizing their patients’ safety, and increasingly dying from drug diversion overdoses.

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.

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.

Chronic pain affects more than 100 million adults in the United States, resulting in disability, loss of work productivity, and overall reductions in health, making chronic pain a major public health problem with an economic burden estimated at $560–635 billion annually. Opioids, the most frequently prescribed class of drugs to control pain, lack evidence supporting their long-term efficacy and carry a 15% to 26% risk of misuse and abuse among pain patients. Guided imagery (GI) is an effective non-pharmacological intervention for reducing pain, but its effectiveness is limited by patients’ imaging abilities. This project will develop and assess the feasibility of an at-home virtual reality system, Limbix VR Kit, to reduce chronic pain and opioid reliance, as well as improve other functional outcomes, by delivering an immersive GI experience.

 Quell Therapeutics uses the Optopatch platform for making all-optical electrophysiology measurements in neurons at a throughput sufficient for phenotypic screening. Using engineered optogenetic proteins, blue and red light can be used to stimulate and record neuronal activity, respectively. Custom microscopes enable electrophysiology recordings from 100’s of individual neurons in parallel with high sensitivity and temporal resolution, a capability currently not available with any other platform screening technology. Here, researchers combine the Optopatch platform with an in vitro model of chronic pain, where dorsal root ganglion (DRG) sensory neurons are bathed in a mixture of inflammatory mediators found in the joints of osteoarthritis patients. The neurons treated with the inflammatory mixture become hyperexcitable, mimicking the anticipated cellular pain response. Investigators calculate the functional phenotype of arthritis pain, which captures the difference in action potential shape and firing rate in response to diverse stimuli. The team will screen for small molecule compounds that reverse the pain phenotype while minimizing perturbation of neuronal behavior orthogonal to the pain phenotype, the in vitro “side effects.” The highest ranking compounds will be chemically optimized and their pharmacokinetic, drug metabolism, and in vivo efficacy will be characterized. The goal is to advance therapeutic discovery for pain, which may ultimately help relieve the US opioid crisis.

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.

Millions of Americans undergo surgery each year, with fewer than half of patients reporting adequate postoperative pain relief and approximately 75 percent reporting moderate to severe postoperative pain. Gaps in postoperative pain management that lead to the unnecessary introduction and over-prescription of opioids continue to exacerbate the opioid crisis, but virtual reality (VR) has been demonstrated to be an effective strategy for pain management. This project will enhance and improve the functionality of a VR-based technology, AppliedVR, to provide acute perioperative pain management through a new software-based VR medical device, RelieVRx™. As a non-opioid alternative intended to reduce postoperative pain, RelieVRx can potentially reduce the need for and utilization of opioids in the postoperative setting.

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.

Managing the risks and benefits of opioid medications can be difficult. Although prescription opioids alleviate pain for some patients, serious adverse effects include opioid use disorder. There is a critical, unmet need for new technologies that significantly minimize the opioid doses needed for effective relief from moderate to severe pain. This project will develop a novel combination treatment containing a small amount of morphine along with pramipexole, a drug approved by the U.S. Food and Drug Administration for Parkinson’s disease and restless legs syndrome that reduces the reward-seeking behavior associated with opioids. The research will conduct safety studies to enable testing in human research participants.

Novel therapies that could alleviate the severe symptoms of opioid withdrawal and/or reduce risk of relapse could help address the devastating opioid crisis. Memantine, an FDA-approved NMDA receptor antagonist, has shown encouraging results as an adjunct to existing opioid use therapies. Its therapeutic efficacy likely derives from its preferential binding to NMDA receptors located outside the synapse, since broad spectrum NMDA receptor antagonists are associated with multiple clinical side effects. This project will use a preclinical model to evaluate a nanostructured version of memantine (AuM) that physically prevents its binding to synaptic NMDA receptors but allows activation of extrasynaptic receptors with potency exceeding that of free memantine.

To avoid the reliance on opioids for treatment of pain, researchers are investigating alternative approaches to disrupt the transmission of pain signals by specialized neurons in the body, such as dorsal root ganglion neurons in the spinal cord. Molecules called voltage-gated sodium channels that are located in the membranes of dorsal root ganglion neurons are essential for transmission of the pain signals. People carrying a specific variant of these channels, NaV1.7, are insensitive to pain; therefore, strategies to block this particular channel might help in the development of non-addictive pain treatment approaches. Navega Therapeutics is developing an innovative gene therapy that specifically targets NaV1.7. Using studies in human cell lines, they will identify the best designs to then test this gene therapy approach in human dorsal root ganglion neurons.
