Clinical trials

This project will evaluate the ability of Mirtazapine (MZP), a pharmacologically unique medication with a growing body of evidence to support its efficacy and safety for the treatment of methamphetamine (MA) use among medication for opioid use disorder (MOUD) patients, to significantly decrease MA use and related health-impairing behaviors. MZP has already successfully been used in the treatment of methamphetamine (detailed further below and in the Appendices). The investigators hypothesize that those assigned to the MZP plus treatment as usual (TAU) MZP+TAU arm will demonstrate significantly increased rates of biochemically verified abstinence from MA and other substances of abuse and experience improvements in health impairing behaviors relative to the placebo (PLO)+TAU arm across the 10-week treatment and follow-up periods.

Using a randomized controlled trial (RCT), the goal of this study is to evaluate the ability of evidence based behavioral treatment (contingency management: CM) to significantly decrease alcohol use and cigarette smoking among treatment-seeking smokers with an alcohol use disorder (AUD) who have initiated pharmacotherapy (varenicline; VC) for smoking cessation.

The goal of this clinical trial is to determine how two different doses of cannabidiol (CBD), given as a hemp product, change the blood concentrations of the drug clopidogrel in the body. Results will be used to help design future studies and to assist healthcare providers in informing their patients about the safe use of CBD.

The purpose of this clinical trial is to determine how the supplement oregano affects how the body metabolizes pharmaceutical drugs.

The purpose of this pilot study is to gather preliminary data on the (1) contribution of the understudied drug metabolizing enzyme, UDP-glucuronosyltransferase (UGT) 2B17, to the metabolism of a widely used medication, diclofenac, and (2) impact of the UGT2B17 inhibitor and natural product, curcumin, on diclofenac pharmacokinetics. Results will inform future studies aimed to assess the effects of UGT2B17 genetic polymorphisms and co-consumed xenobiotics on the pharmacokinetics and toxicity risk of diclofenac and other UGT2B17 drug substrates.

The goal of this study is to investigate whether the botanical product kratom affects how the body processes the opioid drug oxycodone. The main research questions to be answered are two-fold: 1. How does kratom affect the manner in which oxycodone is metabolized (broken down and removed) by the body? 2. Does kratom change the effects oxycodone exerts on the body? Healthy adult participants will complete four study arms, during which they will be given the following: * Kratom (as a tea) * A single dose of oxycodone (as a tablet) * Kratom tea and a single dose of oxycodone * Kratom tea for four days, then kratom tea and a single dose of oxycodone

This study will examine how a moderate dose of THC affects mood, stress responses, and cognitive functioning in regular cannabis users. The study uses a double-blind, placebo-controlled, crossover design, meaning each participant will complete two sessions. Specifically, each participant will be given active cannabis (20 mg THC) in one session, and placebo in the other session. The order will be randomized across participants, so half will receive cannabis first, and the other half will receive placebo first. Ninety adults who use cannabis at least weekly will be recruited from the local community. After an online screening survey, eligible participants will attend a laboratory visit where the participants will provide informed consent and complete saliva and urine drug tests to confirm recent abstinence from cannabis and absence of other drugs. Participants who pass screening will complete baseline questionnaires of cannabis use patterns, depression, anxiety, ADHD symptoms, emotion regulation, affect, and demographic information. Cannabis and placebo materials (obtained from NIDA) will be vaporized using a Volcano vaporizer device. Participants will inhale the vapor under supervision, and neither the participant nor the researcher assessing outcomes will know which product is administered. After vaping, participants will complete repeated mood ratings, saliva samples, and a battery of cognitive tests assessing executive functions like planning, inhibition, working memory, and cognitive flexibility. Participants will also complete a standardized stress challenge (the Maastricht Acute Stress Test), which involves repeated trials of placing their hand in cold water and doing challenging mental math, followed by additional mood ratings and saliva samples. The participants will then watch a nature video and report their feelings of awe and affect. At the end of each session, participants will remain in a supervised room with entertainment and snacks until at least four hours have passed since vaping and the participants report feeling sober. The participants will then return for a second session with the opposite study condition (THC or placebo) one week later. Both sessions follow the same procedures. Participants are fully debriefed after completing the study.

The study aims to explore the potential of Transcranial Magnetic Stimulation (TMS), particularly Theta Burst Stimulation (TBS), as an adjunctive treatment to enhance recovery outcomes (consumption and craving; withdrawal symptoms; mental, physical, sleep, and cognitive health; engagement with therapy, etc.) in individuals with Opioid Use Disorder (OUD) and individuals with Alcohol Use Disorder (AUD). This project will be completed in partnership with Another Chance Rehab (Portland): Portland's top addiction treatment program offering evidence-based treatment programs for a range of substance use disorders. Another Chance Rehab will serve as the project site for this work.

The purpose of this study is to examine the impact of timed cortisol release or differently timed cortisol rhythms on insulin resistance in both men and women undergoing sleep restriction. Chronic sleep loss is highly prevalent, affecting 1 in 3 adults in the US. Chronic sleep loss causes stress which induces insulin resistance and leads to obesity and type 2 diabetes. Many factors contribute to sleep loss including shift work, environmental disturbances, sleep/circadian disorders and comorbid medical and mental health conditions. Sleep loss increases the stress hormone cortisol in the evening and decreases daytime testosterone. Examining these hormones in a controlled laboratory environment under different sleep schedules may help researchers find solutions for adults experiencing negative health consequences related to chronic sleep loss.

The overarching goal of this study is to develop and examine the feasibility of a music-listening intervention that can be deployed in "real time" to regulate emotions and reduce momentary stress among young adults within the first 12 months of recovery from alcohol use disorder. The investigators design the study with two phases to address three aims: Phase I includes the first two aims. For Aim 1, the investigators will conduct formative research with a sample of young adults who have are within 12 months of recovery (N = 30) to identify features of music selections that are most effective in reducing momentary stress in real-world, ambulatory settings. For Aim 2, the investigtors will focus on developing mobile health technology that uses passive sensing and machine learning to automatically predict moments of heightened stress in real-time and suggest specific musical selections when stress is detected. During Phase II (Aim 3), the investigators will test the feasibility of a novel music-listening intervention among a second unique sample of young adults who are within 12 months of recovery from AUD (N = 30). This protocol refers only to Phase II of the larger study.

The purpose of the study is to examine the impact of hemp-derived minor cannabinoids on symptoms of menopause/perimenopause.

Family members/support persons' engagement in mental health services has been linked to reduced burden and stress and improves engagement and outcomes in individuals in the early stages of psychosis. The goal of FAMES is to address low family member/support person engagement in services. FAMES will also address disparities in coordinated specialty care (CSC) by using a culturally responsive family engagement strategy to be delivered by family peers.

This research project will develop and implement a motivational interviewing and electronic messaging intervention to address obstructive sleep apnea (OSA), positive airway pressure (PAP) adherence, and risk of Alzheimer's disease and related dementias in American Indians. The project will work with American Indian Elders, aged 50 years and older, from three Northern Plains Reservations and surrounding communities. A total of 300 American Indian elders with a confirmed OSA diagnosis and prescribed PAP therapy will be randomized to receive usual care consisting of PAP therapy alone (control condition) or usual care plus the culturally informed CATNAP MI component (intervention condition).

The overall objective of this program of research is to utilize phosphatidylethanol (PEth), a blood-based biomarker that can detect alcohol use for up to 28 days to deliver a feasible telehealth-based 26-week CM intervention. This study will test a telehealth PEth-based CM model in a sample of adults with AUD (n=200), recruited via online platforms by randomizing individuals to six months of 1) an online cognitive behavioral therapy for AUD (CBT4CBT) and telehealth PEth-based CM (CM condition) or 2) CBT4CBT and reinforcers for submitting blood samples (no abstinence required) (control condition). Investigators will assess group differences in PEth-defined abstinence and regular excessive drinking (PEth \>= 200 ng/mL), and alcohol-related harms (e.g., smoking, drug use). This study will address important gaps in CM research by assessing outcomes during a 12-month follow-up, which is much longer than most previous CM studies; using a conceptual model to identify predictors of post-treatment abstinence. Investigators will conduct an economic analysis to place the cost of this model in the context of downstream CM-associated cost-offsets and improvements in personal and public health.

Building upon formative research, this mixed methods study will be conducted in three phases to develop, refine, and pilot-test a multi-component Family Peer Navigator model designed to increase access to and initial engagement in coordinated specialty care for early psychosis among Black/African American families.

INTACT will utilize a group-randomized trial, to test the effectiveness of a culturally informed provider training and "dementia friendly clinic" intervention for detection and appropriate management of AI/AN patients with ADRD and MCI in 28 urban and rural clinics serving AI/ANs.

The Automated Reinforcement Management Systems Phase II (ARMS II) study is a phase II trial is a randomized controlled, non-medicated assisted trial to determine the effectiveness of Contingency Management (CM) treatment for reducing alcohol drinking among adults who want to quit or reduce their alcohol consumption.
