Funded Projects

Opioid overdose deaths disproportionately affect Black individuals in the United States. While the use of complementary and integrative pain treatments is effective and widely recommended, Black pain patients (especially those who also have depression) face barriers to the use of these approaches. This project will refine, test, and prepare to implement a novel approach to overcoming these treatment barriers. The research will partner with and empower Black patients to find safe, effective pain treatments that best match their values, preferences, and lifestyles.

The opioid crisis has been particularly devastating to adolescents and young adults between 16 and 25 years old. Recovery support services in community settings can help these individuals who take medications for opioid use disorder find a path to recovery. This project will develop a network of advanced researchers, recovery support specialists, adolescents and young adults in recovery, and other key community stakeholders to help rapidly advance the science of recovery support services. This research will focus in particular on continuing care services specialized for adolescents and young adults who currently take or who have taken medications for opioid use disorder.

There are currently no medications approved by the U.S. Food and Drug Administration to treat methamphetamine use disorder, even though risky patterns of methamphetamine use and overdose deaths have increased in recent years. Research using animal models shows that immune molecules that latch onto methamphetamine (anti-methamphetamine antibodies) show promise in blocking the effects of the drug. This project aims to identify a long-acting monoclonal antibody targeted to methamphetamine and conduct development and safety studies to prepare for future testing of the antibody treatment in humans.

People who take medications for opioid use disorder as part of their recovery pathway need to take these medications for extended periods of time to reduce risk of overdose. Recovery community centers, which provide a range of recovery-oriented and peer-delivered services in a welcoming environment, may be an important asset for these individuals. This project joins two recovery community centers that serve Black communities with an academic research team to inform the design of a rigorous, large-scale clinical trial to determine if clinical referral to recovery community centers improves long-term recovery outcomes.

Young adults (18 to 26) with a substance use problem have the highest rates of polysubstance use among all age groups. At the same time, individuals in this age group (especially in rural areas) are generally lacking in recovery capital: resources to help them recover from substance use, such as vocational or educational skills. This project will assess the feasibility and acceptability of “Launch,” which uses parental and peer recovery support to increase recovery capital for young adults with polysubstance use. The intervention will use coaching as well as contingency management, a treatment approach in which individuals receive tangible rewards as incentives for desired behaviors such as abstinence. If successful, the findings will inform a future large-scale trial assessing the effectiveness of this approach.

The widespread availability of fentanyl and other potent synthetic opioids has dramatically increased opioid-related fatal overdoses. This project will develop and manufacture immune molecules (monoclonal antibodies) to reverse and treat overdose from fentanyl by keeping it out of the brain. This research will advance promising results in animal studies (preventing and reversing fentanyl- and carfentanil-induced breathing problems and irregular heartbeat) to clinical testing in people with opioid use disorder and others at high risk of opioid overdose from accidental or deliberate exposure to fentanyl and fentanyl-like drugs.

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.

Chronic pain severely reduces the quality of life and ability to work for millions of Americans. Because misuse of opioids for chronic pain treatment contributes to opioid addiction and opioid overdose, there is an urgent need to study novel non-opioid mechanisms, targets, and treatment strategies for chronic pain. Many ion channels control the flow of electrical signals in peripheral sensory neurons and are thus key targets for understanding and treating chronic pain. This project will conduct detailed studies to identify major ion channel-related molecular activities, targets, and treatment strategies for chronic pain. In particular, this research will explore the role of a specific ion channel (lysosomal mechanosensitive ion channel, orTmem63A) in neuropathic pain resulting from nerve injury.

This research project will investigate the cannabinoid receptor 2 protein (CB2R) as a novel therapeutic target for opioid-induced respiratory depression caused by fentanyl, oxycodone, and heroin. This study will shed light on how the endocannabinoid system in the brainstem works to control breathing under normal conditions and during opioid-induced respiratory depression. The research aims to determine whether activation of the CB2R with a brain-penetrant CB2R-binding molecule is safe and clinically useful for treating opioid overdose prevention and reversal. This research will pave the way for discovering new medications that activate CB2R to reduce opioid-related deaths.

There is an urgent need for novel substance use disorder treatments aimed at treating polysubstance use disorders, such as opioid and methamphetamine co-use. One promising new target is the peptide ghrelin, which recent studies have implicated in drug- and reward-relevant behaviors. This research project will investigate the recently identified enzyme, ghrelin deacylase, that affects the activity of ghrelin to attenuate the rewarding and reinforcing effects of fentanyl and heroin in combination with methamphetamine. The researchers will also design and test new, long-acting forms of ghrelin deacylase that may be potential therapeutic candidates for the treatment of polysubstance use disorders.

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.

Given recent increases in co-use of opioids and methamphetamine, there is a dire need for novel treatment strategies that prevent relapse to drug use in both opioid use disorder (OUD) and methamphetamine use disorder (MUD). The localization of certain receptors for the neurotransmitter glutamate—metabotropic glutamate receptor subtypes 2 and 3 (mGlu2/3)—and the mechanism through which they transmit signals, strongly suggest that activation of both of these receptors will effectively treat multiple symptoms that contribute to relapse, such as responsiveness to drug cues, physical withdrawal symptoms, neuroinflammation, and sleep disturbances. This project seeks to evaluate molecules that can activate mGlu2/3 receptors without binding to the same site as glutamate (i.e., positive allosteric modulators) as a novel pharmacological treatment for preventing relapse to OUD. The research also will examine the potential of such modulators for treating MUD.

This research is intended to create multidisciplinary team science collaborations to develop effective interventions, best models of care for delivery of services, and sustainable implementation strategies for access to quality care for complex patients with chronic pain and opioid use disorder or opioid misuse. To allow comparison and analysis of data created in nine unique clinical trials funded across four centers, common data elements (CDEs) were selected to assess all aspects of a patient’s condition and experience. The purpose of this project is to make the IMPOWR CDE data more FAIR (Findable, Accessible, Interoperable, Reusable) by building a tool that will automate the mapping/conversion of HEAL-related data to the Observational Medical Outcomes Partnership data model that allows for systematic analysis of data from different databases. Upon completion, this tool would be shared with the HEAL research community as a new resource to enable broader harmonization and secondary data analysis.
