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.

New Mexico (NM) is an epicenter of the opioid crisis in the United States. Many challenging social determinants, including poverty and unemployment, contribute to high rates of opioid use disorder (OUD) in NM. The aims of the NM node are to (1) develop and maintain a highly efficient platform to conduct clinical trials that will inform evidence-based prevention and treatment of OUD; (2) collaborate on and lead research that addresses and improves outcomes across the OUD Cascade of Care (CoC); and (3) promote uptake of best practices in OUD prevention and care in NM and nationwide through effective dissemination of evidence-based innovations. NM node research will ensure the development of robust and generalizable methods for prevention, identification, and treatment of OUD, including evaluation and modification of the CoC to expand the local and national knowledge base.

Emergency department (ED)-initiated buprenorphine/naloxone (BUP) with referral for ongoing BUP is superior to referral alone in engaging patients with untreated opioid use disorder (OUD) in treatment at 30 days and is cost-effective. However, logistical barriers exist in translating research into practice. New BUP formulations such as the extended-release injectable BUP (CAM2038, XR-BUP) hold promise in addressing many of the barriers more effectively than sublingual buprenorphine (SL-BUP) by treating the patients’ symptoms for up to seven days. This study will recruit, train and provide resources to 30 ED sites throughout the U.S. using implementation facilitation strategies to address stigma and provide ED-initiated BUP for patients presenting with OUD who are not receiving medications for OUD. Once implementation is adequately achieved, the sites will conduct a randomized controlled trial (RCT) to compare the effectiveness of SL-BUP versus XR-BUP on ED patients’ engagement in formal addiction treatment seven days after their ED visit. In addition, in an ancillary component of the study, the use of XR-BUP will be assessed in ED patients with Clinical Opioid Withdrawal Scale (COWS) scores of

Often (around 40 percent of the time), individuals being treated for opioid use disorder (OUD) also have pain that interferes with daily life. This study builds on the prior development of a collaborative primary care approach, entitled TOPPS (Treating Opioid Patients’ Pain and Sadness), in which behavioral health specialists and primary care providers share a unified plan for addressing pain and depression in patients receiving buprenorphine. Building in preliminary work, researchers are conducting a randomized controlled trial of TOPPS compared to a health education contact-control condition among 250 persons with OUD recruited from two primary care-based buprenorphine programs, provided over 3 months and followed over 12 months. The study will examine whether this intervention changes how much pain interferes with daily functioning, the severity of pain, depression, and whether individuals stay in OUD treatment.

In 2015–2016, there were over 2 million adults with an opioid use disorder (OUD); 62% had a co-occurring mental illness and 24% had a co-occurring serious mental illness. Despite the effectiveness of treatment, many individuals never receive it, and when treatment is provided, quality is low. This is a critical treatment gap in a vulnerable and stigmatized population. Collaborative care (CC) aims to address these gaps by improving access, quality, and outcomes in primary care patients with common mental health conditions. However, CC has never been tested with co-occurring disorders (COD). In the team’s CC model for COD (CC-COD), the CC team includes a behavioral health psychotherapist, medications for OUD, pharmacotherapy for depression and post-traumatic stress disorder (PTSD), motivational interviewing (MI), problem-solving therapy, and Seeking Safety. A multisite, randomized pragmatic trial will be conducted to adapt, harmonize, and then test whether CC-COD improves access, quality, and outcomes for patients with comorbid OUD and depression and/or PTSD.

Adolescents face increased HIV risk, infrequent testing, inconsistent linkage to care, and a lack of prevention-related knowledge. We propose to complete and evaluate the Mobile Augmented Screening (MAS) tool to privately and discretely offer routine HIV testing and counseling, including prevention education, to high-need, diverse adolescent and young adult populations at a low cost. The MAS will consist of a tablet-based intervention including a brief video designed to increase adolescent HIV testing, automated text messages to facilitate linkage to care for those who test positive, and text-based education for those who test negative or decline testing. Phase I was conducted with young emergency department (ED) patients. Preliminary evaluations indicate the video led to significant knowledge increases and encouraged testing. In phase II, we seek to complete intervention development and evaluate through a randomized controlled trial with ED patients, with qualitative interviews for a subset of young patients and ED staff.

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.

Less than half of youth in the juvenile justice system who meet the criteria for substance use disorders (SUD) have ever received treatment, and less than one third of those received treatment while under community or correctional supervision. SUDs during adolescence can lead to significantly longer periods of substance use, more severe offending, and penetration in the justice system. The Translational Research on Interventions for Adolescents in the Legal System (TRIALS) cooperative is intended to develop and test implementation strategies and associated measures to improve the continuum of substance abuse and HIV prevention and treatment services delivered to youth under juvenile justice supervision.

Prevalence rates of opioids misuse in Los Angeles County (LA) are particularly high among individuals of childbearing age and in already-vulnerable populations including African American females. These data highlight a pressing need for a systematic study of the effects of prenatal drug exposures (PDE) in the unique sociodemographic LA County area. In this project, researchers aim to establish the feasibility for the large-scale Phase II HEALthy BCD study in the Los Angeles area with three specific aims: (1) build a broad interdisciplinary team of investigators capable of a multi-faceted study of brain and behavioral development in both typically developing and at-risk infants/children; (2) establish a set of highly executable recruitment and retention strategies for both drug-free and drug-exposed infants/children; and (3)establish comprehensive study protocols that will help address the three key research objectives of the Phase II study.

Opioid use disorder (OUD) can be lethal, with opioid overdose causing more than 115 deaths in the U.S. each day. Although medications are effective at reducing illicit opioid use and overdose deaths, it is well-established that withdrawal and craving are highest in the initial weeks, making this a high-risk period for treatment dropout, relapse, and overdose. Adjunct therapies that can reduce early opioid withdrawal and craving may improve retention in treatment with buprenorphine-naloxone, and recent research has shown that stimulation of a peripheral nerve significantly modulates withdrawal- and craving-related responses for opioids and other drugs. This project will test the effectiveness of the EMPOWER Neuromodulation System, a portable, non-invasive transcutaneous electrical nerve stimulation (TENS) device developed by TheraNova for the treatment of OUD.

The orbitofrontal cortex (OFC) plays an important role in regulation of addiction, and OFC impairment from cocaine and opioids use leads to repetitive drug use. Brief optogenetic activation of the OFC reduces self-administration of drugs in neurobiology studies. However, the OFC is less accessible for noninvasive stimulation using direct transcutaneous current stimulation or transcranial magnetic stimulation. The small business EvON Medics LLC and Howard University have created a home-based olfactory pulsing prototype, called computerized chemosensory-based orbitofrontal cortex training (CBOT), using a high-fidelity chemosensory and computerized olfactory training approach to enable home-based neuromodulation of the OFC for treatment of opioid use disorder (OUD). A pilot feasibility study in OUD samples suggests that CBOT can minimize withdrawal symptoms, reduce drug cravings, enhance positive affect, and reduce rate of positive urine drug tests. The project seeks to establish CBOT stimulation parameters needed to maximally improve outcome inference and emotion regulation in OUD.

A more than 5-fold increase in the incidence of neonatal abstinence syndrome has been reported since 2000. Preliminary studies show that prenatal opioid exposure is associated with increased risk of impaired neurodevelopment. Five institutions (Duke University, Arkansas Children’s Research Institute, Cincinnati Children’s Hospital, University of Illinois at Urbana–Champaign, and University of North Carolina at Chapel Hill) have formed a consortium to develop strategies for the Phase II HEALthy Brain and Child Development Study. Research teams will develop instruments and strategies (recruitment/retention protocols, assessment batteries, and novel tools); conduct pilot studies (fetal and postnatal imaging, advanced imaging harmonization and quality control, assessment administration, biosampling) to evaluate instruments; and analyze available data, including imaging, behavioral, cognitive, and maternal data from studies on early brain development, to guide the Phase II study design. Upon completion, the consortium aims to conduct the Phase II study.

For many individuals in recovery from a substance use disorder, certain cues—including stress and drug-related cues—can trigger a physiological state in which they are more likely to relapse. In this SBIR project, the investigators intend to deploy a system—consisting of a wearable sensor, a smartphone app, and a clinical portal—to provide individuals in recovery and their treatment providers with an opportunity to identify moments of high risk for relapse and to access real-time intervention opportunities. The sensors will identify signals of stress or drug use, interface with a smartphone app, and provide options for annotations, stress-reduction techniques, or contact with an individual’s support system and treatment providers, as well as log and encourage healthy behaviors. This study will deploy and optimize the system, as well as test its effects on addiction-related outcomes, such as rate of relapse.
