Smartphones for Opiate Addiction Recovery
Treatments for opioid addiction exist, but effectiveness is compromised when subjects use illicit opiates during treatment. Reuse rates during treatment can be high, and reducing illicit opiate use during treatment has thus recently become a major NIDA policy goal. The 5-minute battery indicates the numerical probability that a patient will reuse illicit opiates within the next 7-10 days.

Encouraging Abstinence Behavior in a Drug Epidemic: Optimizing Dynamic Incentives
Combatting the rise of the opioid epidemic is a central challenge of U.S. health care policy. A promising approach for improving welfare and decreasing medical costs of people with substance abuse disorders is offering incentive payments for healthy behaviors. This approach, broadly known as "contingency management" in the medical literature, has repeatedly shown to be effective in treating substance abuse. However, the use of incentives by treatment facilities remains extremely low. Furthermore, it is not well understood how to design optimal incentives to treat opioid abuse. This project will conduct a randomized evaluation of two types of dynamically adjusting incentive schedules for people with opioid use disorders or cocaine use disorders: "escalating" schedules where incentive amounts increase with success to increase incentive power, and "de-escalating" schedules where incentive amounts decrease with success to improve incentive targeting. Both schemes are implemented with a novel "turnkey" mobile application, making them uniquely low-cost, low-hassle, and scalable. Effects will be measured on abstinence outcomes, including longest duration of abstinence and the percentage of negative drug tests. In combination with survey data, variation from the experiment will shed light on the barriers to abstinence more broadly and inform the understanding of optimal incentive design.

Effective Caregiving for Neonatal Abstinence Syndrome: Testing an Instructional Mobile Technology Platform for High-Risk Pregnant Women
Most newborns experiencing Neonatal Abstinence Syndrome (NAS) require non-pharmacologic care, which entails, most importantly, maternal involvement with her newborn. To facilitate positive maternal-newborn interactions, mothers need to learn effective caregiving NAS strategies while they are pregnant, yet, an enormous gap exists in the early education of mothers on the symptoms and progression of NAS, in part because no interventions exist to prepare future mothers for the challenges of caring for their newborns at risk for NAS. In this project, the investigators propose to adapt an existing mobile NAS tool for high-risk pregnant women and assess its usability, acceptability, and feasibility in a small randomized controlled analog trial.

The Youth Opioid Recovery Support (YORS) Intervention
Youth are disproportionately affected by the current opioid crisis with catastrophic consequences, and young adults with opioid use disorder (OUD) often struggle with adherence to relapse prevention medications. The Youth Opioid Recovery Support (YORS) model is a promising, innovative, wrap-around approach that addresses barriers to medication adherence and treatment engagement in an effort to improve public health outcomes in this vulnerable young adult population. This study seeks to refine the YORS intervention through stakeholder input and pilot iterative testing followed by an efficacy randomized controlled trial. This project will significantly contribute to our knowledge base of practical strategies to address the opioid crisis.

Therapy and Peer Support for Patients Taking Medication for Opioid Use Disorder
Current clinical guidelines for medication assisted treatment (MAT) of opioid use disorder (OUD) recommend that treatment include a psychosocial component to help address psychological factors related to addiction. However, a knowledge gap exists regarding the most effective forms of psychosocial intervention and what interventions are most effective for different types of patients. This gap represents a significant barrier to the widespread implementation of effective office-based opioid treatment (OBOT) with buprenorphine, which is important to improving opioid treatment and responding to the critical needs of individuals living with OUD. The overarching goal of this patient-centered research is to address the diverse needs and preferences of OUD patients in regards to psychosocial approaches and to overcome the "one-size-fits-all" strategies that are typically used to treat OUD. Importantly, the investigators arrived at this goal, in part, through collaboration and consultation with former patients who have received different types of treatments for OUD. In this manner, patients provided important insight to inform the selection of interventions to be evaluated, patient characteristics that may differentially impact the effects of the interventions, and the patient outcomes to be examined.

Project I Test: Implementing HIV Testing in Opioid Treatment Programs
This study will test two active evidence-based "practice coaching" (PC) interventions to improve opioid treatment programs' (OTPs') provision and sustained implementation of on-site 1) HIV testing and linkage to care and 2) HIV/Hepatitis C virus (HCV) testing and linkage to care among patients seeking/receiving substance use disorder treatment. Aims are: Aim 1: To evaluate the effectiveness of the PC interventions on improving patient uptake of HIV testing in OTPs including the incremental impact of the HIV/HCV intervention on HIV testing. Aim 2: To examine, using mixed-methods, the impact of the PC interventions on the initiation and sustained provision of HIV testing and timely linkage to care. Aim 3: To evaluate the health outcomes, health care utilization, and cost-effectiveness of the PC interventions compared incrementally to one another and to the control condition. Primary Hypothesis: 1. The two PC interventions will result in significantly higher proportions of patients tested for HIV than the information control condition during the "initial impact" period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Primary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary). 2. The HIV/HCV PC intervention will result in significantly higher proportions of patients tested for HIV than the HIV PC intervention during the initial impact period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Secondary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary).

Neuromodulation and Cognitive Training in Opioid Use Disorder
The relapsing nature of opioid use disorder is a major obstacle to successful treatment. About 90% of those entering treatment will relapse within one year. To improve treatment outcome, new interventions targeting the underlying brain biomarkers of relapse vulnerability hold significant promise in reducing this critical public health problem. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that can modulate brain connectivity.

Evaluating Buprenorphine/Naloxone Microdosing vs. Standard Dosing in Emergency Departments
This is a multi-centre, open-label RCT at four Emergency Departments (EDs) in British Columbia and Alberta. The purpose of the current study is to compare the effectiveness of buprenorphine/naloxone microdosing and standard dosing take-home induction regimens at enabling patients to successfully complete the induction regimen, and at retaining patients on opioid agonist therapy. We will randomize our enrolled patients to receive take-home microdosing or standard dosing packages of buprenorphine/naloxone. For the microdosing arm, patients immediately start taking low doses that increase to effective levels without requiring them to go into withdrawal. We hypothesize that ED patients provided buprenorphine/naloxone microdosing packages will be more likely to successfully complete the induction period compare to patients provided standard dosing packages. We furthermore hypothesize that those provided microdosing will be more likely to be retained in opioid agonist therapy, and will experience lower overdose, mortality, and healthcare utilization subsequent to their ED visit.

Efficacy of Buprenorphine and XR-Naltrexone Combination for Relapse Prevention in Opioid Use Disorder
This study will evaluate the effectiveness of a new pharmacological approach to increase efficacy of treatment with extended release naltrexone (XR-naltrexone) for individuals with opioid use disorder by combining it with buprenorphine-naloxone. This is a two arm, double-blind, placebo-controlled study to examine whether addition of buprenorphine-naloxone will improve treatment retention, reduce opioid craving, and improve mood over 24 weeks of treatment with extended release naltrexone (XR-naltrexone) administered every four weeks for a total of 6 injections. The NYSPI site, which provides study oversight (no direct participant involvement) is currently paused and has been paused since an institutional pause on human subjects research began in June, 2023. The U.S. Department of Health and Human Services (HHS) Office of Human Research Protections (OHRP) issued an FWA restriction on NYSPI research that also included a pause of human subjects research as of June 23, 2023.

Clinical Trials of Multivalent Opioid Vaccine Components
Currently, abuse of prescription opioid analgesics and heroin is a serious problem in the U.S. Although several medications, including methadone, buprenorphine, and naltrexone, are available and effective in treating opioid use disorder (OUD), long-term relapse rates remain high. The current study is designed to examine a new approach to treating OUD, namely use of a vaccine targeted against oxycodone \[Oxy(Gly)4-sKLH\], one of the most commonly abused prescription opioids. The vaccination approach to treating substance use disorders relies on the ability of the vaccine to produce antibodies that bind the target drug in blood and reduce its ability to enter the brain. The long-term goal of this research will be to develop a combined vaccine against oxycodone and heroin. However, in this trial the Oxy(Gly)4-sKLH vaccine will be studied separately. This is a multi-site study, being conducted at the New York State Psychiatric Institute and the Clinilabs clinical research unit (CRU) in Eatontown, New Jersey. The current study proposes to evaluate safety (Aim 1), degree of antibody production (Aim 2), and efficacy (i.e., ability to reduced drug liking following opioid administration) (Aim 3). The oxycodone vaccine (Oxy(Gly)4-sKLH) will be tested in participants with OUD (target # completers = 45 across two study sites). This study will provide a great deal of information about the safety and potential effectiveness of the Oxy(Gly)4-sKLH vaccine in reducing the abuse of opioids. The NYSPI site is currently paused and has been paused since an institutional pause on human subjects research began in June 2023. The U.S. Department of Health and Human Services (HHS) Office of Human Research Protections (OHRP) issued an FWA restriction on NYSPI research that also included a pause of human subjects research as of June 23, 2023.

Imaging Cannabinoid Receptors Using Positron Emission Tomography (PET) Scanning
The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, \[11C\]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.
