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.

There is a need to improve access to treatments and address the stigma, bias, and mistrust that harm and isolate people with chronic pain, especially those from ethnic and racial minority populations. The Integrating Nonpharmacologic Strategies for Pain with Inclusion, Respect, and Equity (INSPIRE) Chronic Pain (CP) intervention blends cognitive-behavioral therapy, physical therapy, mindfulness, and pain education, and is delivered by a trilingual mobile app and supported by a telehealth pain coach who coordinates with doctors. The coach will collect and summarize patient reports on pain, depression, anxiety, substance use, and social factors, and share them with healthcare providers. In this project, researchers will create the digital tool and coaching protocol, develop educational and implementation strategies for healthcare providers, and conduct a pilot test. They will then perform a randomized clinical trial to compare INSPIRE to current treatment, analyze its effects, and evaluate outcomes.

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.

There are currently few effective therapies available for chronic nerve injury-induced pain, associated anxiety, and depression. This project aims to extend previous research aiming to uncover the mechanism of action of artificially modified immune molecules (humanized cholecystokinin-2 receptor [CCKBR] single-chain variable fragments [scFv]) on human neurons and how it reverses chronic pain and anxiety-like behaviors in mouse models. This potential treatment approach offers important advantages over existing therapies, including extreme specificity, higher affinity, brain/nerve penetrance, safety, and reduced self-immunogenicity.

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. 

A more thorough understanding of neuropathic pain is critical for developing new target-specific medications. Researchers know that peripheral nerve injury changes various cell processes that affect two ion channels linked with chronic pain. Preliminary studies indicate that molecular changes known as phosphorylation to the collapsin response mediator protein 2 (CRMP2), one of five intracellular phosphoproteins, promotes abnormal excitability in the brain region that contributes to neuropathic pain. This project aims to develop small molecule inhibitors of CRMP2 phosphorylation as potential therapeutics for pain.

Voltage-gated sodium channels such as Nav1.7, Nav1.8, and Nav1.9 transmit pain signals in nerve fibers and are molecular targets for pain therapy. While Nav channels have been validated as pharmacological targets for the treatment of pain, available therapies are limited due to incomplete efficacy and significant side effects. Taking advantage of recent advances in structural biology and computational-based protein design, this project aims to develop antibodies to attach to Nav channels and freeze them in an inactive state. These antibodies can then be further developed as novel treatments for chronic pain.

This research aims to define factors involved in the transition from acute to chronic pain, toward reducing opioid use and discovering new, non-addictive pain treatments. This project will develop recruitment efforts to engage a diverse patient population in clinical research that results from new findings about the transition from acute to chronic pain. The project will use focus groups, led by experts in health equity and implementation research, and patient navigators to enhance recruitment of diverse research participants.

Emerging adults (ages 16-25) involved with public systems and individuals involved with the justice system (including emerging adults) are at the highest risk for problems stemming from opioid use disorder. Emerging adults report the highest rates of drug use, including opiates, and those involved with public systems are more likely to have poor outcomes. For adults of all ages, opioid use increases the likelihood of justice system involvement. Peer recovery support services and recovery residences are growing nationally and may benefit these two groups tremendously, but research on them is limited. This project will establish the Initiative for Justice and Emerging Adult Populations to advance recovery support services research through a partnership between researchers, people in recovery from these two populations, recovery support service providers, and payors.

Individuals with opioid use disorder tend to be more in need of additional services; feel more isolated and marginalized; have less available resources such as education, training, employment, and housing opportunities (collectively known as “recovery capital”); and report lower quality of life than those with other substance use disorders. Recovery Community Centers (RCCs) are designed specifically to help grow recovery capital and enhance remission and quality of life. Preliminary evidence suggests RCCs are particularly valuable for people with opioid use disorder, but little is known about their clinical and public health benefits and cost-effectiveness. This project will organize activities on a national level to enhance research on RCCs. It builds on existing professional and academic resources, including an established recovery dissemination platform (i.e., the Recovery Research Institute).

The increased presence of fentanyl in cocaine has drastically increased cocaine-related overdoses, yet there is no research quantifying how cocaine users respond to fentanyl adulteration. In this online study, a modification of a behavioral economics measure, the Cocaine Purchase Task, will quantify for the first time how cocaine users respond to fentanyl contamination in cocaine. This study aims to 1) Determine how possible fentanyl adulteration affects cocaine demand, and 2) Determine which individual characteristics moderate the relationship between fentanyl adulteration and cocaine demand. Determining how possible fentanyl adulteration affects cocaine demand can help inform the development of effective harm reduction interventions for people who use cocaine to address the worsening crisis of opioid related deaths.

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.
