Funded Projects

Evidence-based behavioral treatments for pain are among the most effective and safe approaches, but they are underused, especially among patients taking opioids long-term. Despite known risks to long-term opioid therapy (including opioid use disorder and overdoses), patients may be reluctant to try something different to manage their pain. This project brings together two evidence-based behavior change interventions—motivational interviewing and contingency management—into an online format. The research will test whether web-based tools or mobile apps influence a patient’s willingness to consider using non-medication treatments for pain. The research will assess feasibility, acceptability to patients and providers, and broad-scale implementation.

Decreasing opioid dosing faster than advised by clinical recommendations often leaves chronic pain unaddressed and may increase the risk of overdose and suicide compared to continuing long-term opioid treatment. Continued, long-term use of opioids after surgery by individuals who use opioids increases the risk of postoperative complications, opioid use disorder, and death. Surgery is a critical point-of-care moment for health care providers to interact with patients who use opioids about continued opioid use when harms outweigh benefits. This project will test of the Motivational Interviewing and guided Opioid Tapering support (MI-Opioid Taper) strategy, with or without a medication that reduces anxiety and relieves pain, at four geographically diverse hospitals across the nation.

Drug checking services provide individuals who use drugs with information about the true contents of their purchases, and thus may help prevent overdoses. However, current technologies are either costly, technically complex, and non-portable or subject to false signals and restricted in their detection capabilities. This project will continue development of a new, simple-to-use, point-of-care analytical technology (DoseCheck) that can rapidly detect established drug threats in a sample and recognize newly emerging drugs. The project will also attempt to adapt DoseCheck to provide rapid results in emergency overdose situations and improve the analytical capabilities of medical examiners in under-resourced jurisdictions.

Although medication-based treatment for opioid use disorder can effectively reduce overdose risk and improve health outcomes, most people discontinue treatment too soon. Quality measures that inform opioid treatment programs about how many patients remain in treatment relative to peer programs could motivate those programs to pursue quality improvement activities, such as helping patients navigate logistical barriers to receiving treatment. This project will test approaches to developing and disseminating retention and outcome measures for opioid treatment programs.

This project provides protected time for training and research activities that are required for an independent scientific career in the development, testing, and implementation of cutting-edge digital therapies and tools (such as smartphone apps and other web-based resources) that can promote health equity in treatment of opioid use disorder (OUD). The research will adapt and test digital overdose prevention and recovery support interventions for Black Americans with co-occurring OUD and mental illness. 

Novel treatments for opioid use disorder are critically needed as the addiction and overdose crises continue. Neuromodulation is a promising supplemental treatment to standard care. The overarching project seeks to evaluate low-intensity focused ultrasound that targets the nucleus accumbens, a primary component of the brain’s reward neurocircuitry. This supplement will expand the number of participants in part of the study and will increase the project’s overall impact consistent with the original objectives and aims of the parent grant.

There is an urgent need for a new generation of non-addictive, pain-relieving medications that do not cause problematic side effects like breathing problems or constipation. The overarching project is testing a new potential medication that interacts in a new way with the opioid system in human research participants. This supplement will help cover costs associated with the Safety Review Committee meeting required by the U.S. Food and Drug Administration.

There is an urgent need for improved medications to treat OUD. This project will test cebranopadol, a novel synthetic medication that interacts in a new way with the human opioid system as a safe and potentially effective alternative treatment for OUD. The research will test the safety and efficacy of cebranopadol in preclinical and clinical studies, toward guiding future research to support potential approval of this medication by the U.S. Food and Drug Administration.

There is an urgent need for longer acting opioid overdose reversal medications to treat acute fentanyl intoxication and overdose. This project will develop a novel molecule (CS-1103) that sticks to fentanyl and removes it from the body. Previous research with animal models shows that CS-1103 has several features that make it attractive for a new medication. It can reverse fentanyl-induced respiratory depression, preventing another overdose; work in combination with naloxone; and appears to be safe and well-tolerated. The research will continue exploration of CS-1103 toward testing CS-1103 in human research participants.

Opioids can be effective analgesics but can also be fatal due to opioid-induced respiratory depression after overdose. This project will use cutting-edge molecular, physiological, behavioral, and imaging techniques to better understand and distinguish opioid-induced respiratory depression and opioid-mediated analgesia. Nerve cell-specific, single-cell transcriptomic analysis will be used to identify functional markers expressed in nerve cells that play a specific role in opioid-induced respiratory depression, but not opioid analgesia. This research study will help to identify novel therapeutic targets that could selectively rescue opioid-induced respiratory depression while maintaining the beneficial pain-relieving effects of opioids. 

About 23 million Americans identify as being in recovery from opioid and other substance use disorders. While recovery support services are an established best practice to support people in recovery, there is little scientific evidence to support the efficacy and implementation of peer recovery support services, training approaches, and delivery models. Recovery support services are particularly lacking in the U.S. Southwest and for individuals who choose to take medications for opioid use disorder as part of their recovery pathway. This project will establish the Peer Recovery Innovation Network to address research gaps. This research will incorporate input from people with lived experience in all stages of the recovery process – toward helping to set the research agenda and conducting the research, as well as enhancing infrastructure for peer recovery support services research.

Opioid dependence is a leading cause of premature illness and death. Previous research suggests that a protein called G-protein coupled receptor (GPR88) controls many addiction-relevant behavioral and physiological actions of opioids. This research study will validate GPR88 as a drug target for opioid use disorder as well as develop novel, brain-penetrant GPR88-binding molecules with properties optimized for treating opioid dependence. This research is an initial step toward the goal of developing GPR88-binding molecules as novel therapeutics to facilitate abstinence in people dependent on opioids.

Safe and stable housing is widely considered to be critical to recovery from alcohol and drug use disorders. Therefore, providing dedicated safe and substance-free housing options for individuals in recovery (recovery housing) may be an essential component of a comprehensive response to the current opioid crisis. However, there is limited evidence about effective recovery housing practices for individuals choosing treatment with medications for opioid use disorders as part of their path to recovery. This project will enhance the infrastructure necessary to study the effectiveness of recovery housing for these individuals. It will develop a national multi-stakeholder network, host webinars for researchers and recovery housing providers, and support mentored pilot studies for new researchers seeking to study recovery housing.
