Opioid use disorder (OUD) is a key driver of the current opioid epidemic in the United States, but nearly 80% of individuals with OUD do not receive treatment. Buprenorphine medication-assisted treatment (MAT) is an effective form of care for OUD. This project will develop a state-of-the-art, digital therapeutic tool that effectively promotes buprenorphine adherence by providing contingency management rewards and educational content and enables home induction using a new self-monitoring support tool. This tool, named reSET-O+, will be integrated with Pear Therapeutics’ reSET-O, an FDA market-authorized mobile application delivering validated behavioral therapy and intended for use in conjunction with buprenorphine and standard outpatient treatment for OUD.

The U.S. is in the midst of an opioid crisis, and efforts to tackle the complex and dynamic nature of this public health challenge must comprehensively consider a multitude of contributing factors. In response, states have implemented a wide range of policies and initiatives. However, the dynamic nature of the crisis and the speed with which different policy approaches are being implemented pose numerous challenges for researchers evaluating the effects of such efforts. These challenges stem in part from limited information regarding policy implementation; insufficient information about policy characteristics that may influence effectiveness; little consideration of how the chosen analytic method may influence findings, given simultaneous or concurrent implementation of multiple policies; and limited training on how to best communicate findings to policymakers. To address these challenges, the proposed Center for Opioid Policy Research (COPR) will serve as a national resource, fostering innovative and high-quality research in the opioid policy arena and developing and disseminating methods, tools and information to the research community, policymakers and the public.

The HEALthy Brain and Child Development National Consortium (HBCD-NC) will establish a normative model of developmental trajectories over the first 10 years of life. All sites in the HBCD-NC will carry out a common research protocol and will assemble and distribute a comprehensive research dataset to the scientific community. The HBCD-NC will collect neural, behavioral, physiological, and psychological measures, as well as biospecimens, to characterize neurodevelopmental trajectories. Most participants will be recruited in the second trimester of pregnancy, with a smaller subset recruited at birth, and followed for the first 10 years of life. This study will be conducted at Emory University School of Medicine in Atlanta, Georgia, allowing access to a diverse population with a high representation of Black/African American women.

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.

A major driver of the U.S. opioid crisis is limited access to effective medications for opioid use disorder (MOUD) that reduce the risk of overdose. Traditionally, jails and prisons in the U.S. do not initiate or maintain MOUD for inmates with OUD prior to their return to the community, which places them at high risk for fatal overdose. The Massachusetts Justice Community Opioid Innovation Network (JCOIN) will study the outcomes and implementation of a 2018 state law that seven county jails must provide all approved forms of medication for OUD. The Chapter 208 initiative has important implications for future policy and practice in the justice and OUD treatment systems at the local, state, and national levels.

For many reasons, the emergency department (ED) is a critical venue to initiate opioid use disorder (OUD) interventions. ED patients have a disproportionately high prevalence of substance use disorders and are at an elevated risk of overdose, and many do not access health care elsewhere. Despite this, OUD interventions are rarely initiated in EDs. The Emergency Department Connection to Care with Buprenorphine for Opioid Use Disorder study (CTN-0079) will assess the feasibility, acceptability and impact of introducing clinical protocols for screening for OUD, buprenorphine treatment initiation, and referral for ongoing treatment in ED settings with high need, limited resources and different staffing structures. This extension study will use the existing infrastructure to evaluate the adoption and sustainability of the clinical protocols introduced at each of the study sites and to identify factors influencing their diffusion and effectiveness.

People who work in harm reduction settings aiming to keep people with substance use disorders safe from overdose and other negative health outcomes are exposed to high rates of lifetime and occupational stress and trauma. Their work conditions can have adverse effects on patient care and also on their own well-being, such as unmet mental health needs, burnout, and relapse. This project will adapt the Stress First Aid intervention for harm reduction workers. The research will test the impact of this intervention on social support, burnout, secondary traumatic stress, use of mental health care, engagement, and turnover. The long-term goal of this work is to implement a sustainable and effective national occupational stress intervention for harm reduction workers to strengthen their important role in helping individuals get treatment and avoid overdose.

The Planning for the HEALthy Early Development Study will contribute to the design and recommended protocol for a future large-scale, multi-site research study to prospectively examine human brain, cognitive, behavioral, social, and emotional development of children beginning prenatally through ages 9–10 and to determine the impact of maternal pre- and postnatal substance use on short- and long-term development of children. The planning study will link investigators across 6 research sites who have complementary experience and expertise in the areas that are essential to designing the study. Planning activities will be accomplished using a coordinated set of 10 working groups. By the end of the planning phase, the 6 consortium sites will have produced and tested a recommended protocol for the future multi-site study and will have established feasibility of carrying out the study protocol at each of the 6 linked sites.

Chronic pain is a significant public health problem associated with tremendous personal and economic burden. First-line treatment consists of opioid medications, but despite only moderate efficacy and unpleasant side effects, rates of opioid prescriptions have quadrupled over the past 15 years, and this has contributed to high rates of misuse, overdose, and mortality. Clearly, alternative, or non-opioid strategies for treating pain are needed. In this context, “opioid-sparing” medications refer to compounds that can be combined with and enhance the analgesic effects of lower-dose opioids without increasing the rewarding properties of either drug. There is preclinical evidence suggesting that cannabidiol (CBD) may have the potential to function as “opioid-sparing” medications, but its ability to alter opioid-mediated analgesia in humans has yet to be determined. This proposal will fill this gap by conducting a double-blind, placebo-controlled, within-subject randomized crossover study of the effects of CBD and morphine co-administration on pain sensitivity and subjective reinforcement on 28 healthy males and females. This is the first known study to investigate the ability of CBD to alter morphine’s analgesic effects in humans. If successful, the model will have a lasting impact on our ability to develop and test medications that reduce our reliance on chronic use of opioid medications for pain relief.

Despite substantial increases in overdose deaths among people who use methamphetamine, little is known about how to effectively provide harm reduction services to these individuals. This project will combine and test two harm reduction interventions for people who use methamphetamine. First, peer recovery support specialists will help identify personal harm reduction goals. The project will also test the value of incentives toward achieving these goals (a strategy known as contingency management).

Substance use disorder (SUD) is a serious public health and socioeconomic burden. In this project, researchers will develop novel drug compounds that dually target orexin receptors and kappa opioid receptors, which have both been implicated in SUD. The compounds will then be tested for effectiveness in preclinical models of SUD, including models of cocaine, methamphetamine, and fentanyl use. This research has the potential to provide highly impactful and innovative treatment options for SUD via simultaneous modulation of multiple signaling pathways.
