Chicago, IllinoisAges 18 years+ - NCT03713424RecruitingPhase 2
Brain scan study of an antibiotic for drug addiction
This study uses an MRI brain scan to see how taking clavulanic acid affects brain activity related to drug addiction. It may help researchers understand whether this medicine could change how addiction-related cues affect the brain.
Columbia, MissouriAges 18–65 - NCT03745339Recruiting
Smell-based memory task in people with opioid-use disorder
This study tests how people learn and infer what something means using a smell-and-memory task. It compares people with opioid-use disorder who are abstinent, those in maintenance treatment, and healthy controls to see what affects learning and decision-making after opioid use.
Baltimore, MarylandAges 21–60 - NCT04033679Recruiting
Brain stimulation to help people stay on schizophrenia medications
This study tests whether a non-invasive brain stimulation treatment can improve medication adherence in people with schizophrenia or schizoaffective disorder. If it helps you take meds more reliably, it may also support more stable mental health over time.
Toronto, OntarioAges 18 years+ - NCT04325958Recruiting
Test how cannabis affects driving in different age groups
This study looks at how smoked cannabis changes driving performance when compared across two age groups. It may help researchers understand safety risks and differences by age.
Toronto, OntarioAges 19–45 - NCT04373629Recruiting
Testing how flexible appearance worries may change in BDD
This study looks at whether training can change how people with body appearance worries (including body dysmorphic disorder) perceive faces or the head. It may help researchers understand new ways to reduce distress related to these concerns.
Toronto, OntarioAges 18–40 - NCT04379115Recruiting
Brain stimulation study for people with opioid addiction
This study tests a non-invasive brain stimulation approach to reduce opioid cravings in people who are actively using non-prescribed opioids while on stable methadone. It may help people feel less craving and improve recovery support.
Hinsdale, IllinoisAges 18–85 - NCT04478838RecruitingPhase 4
Alternate-day antipsychotic dosing for schizophrenia
This trial looks at whether taking an antipsychotic every other day can keep symptoms controlled in adults with schizophrenia or another psychotic disorder. It may help some people avoid daily dosing, but it requires specific medication stability and screening checks.
Toronto, OntarioAges 18 years+ - NCT04613791Recruiting
Alcohol and addictive behaviors in people with obesity
This study looks at how often people with obesity struggle with alcohol or other addictive behaviors, and how these issues change over time. Understanding this connection may help doctors better support patients managing obesity.
NîmesAges 18 years+ - NCT07145866RecruitingPhase 4
Varenicline and TMS for quitting nicotine use
This study tests whether combining the medication varenicline (Chantix) with a special brain stimulation treatment (TMS) can help people quit vaping or smoking nicotine. If you're motivated to quit and use nicotine daily, you may be able to join.
Boston, MassachusettsAges 18–65 - NCT06408233Recruiting
Improving addiction care in New York
This study looks at how to improve care for people with opioid use disorder in New York State. Researchers want to learn from both patients and their treatment providers to make addiction treatment more person-centered.

Toronto, OntarioAges 18–55 - NCT04972136Recruiting
Brain stimulation treatment for depression in young adults with autism
This trial studies a noninvasive brain stimulation (rTMS) to help reduce depression symptoms in young adults who have autism. It aims to find out if this treatment can improve mood and daily functioning without requiring recent changes to medications.
Toronto, OntarioAges 16–35 - NCT05033028RecruitingPhase 3
Using a smartphone to support opioid addiction recovery
This Phase 3 study tests whether using smartphones can help people with opioid-use disorder stick with treatment and recover more successfully. It focuses on people starting or already in treatment using methadone or buprenorphine, with support delivered through the study app or messages.
Piscataway, New JerseyAges 18–85 - NCT05062369Recruiting
Brain stimulation plus training to support alcohol abstinence
This study tests whether a combination of brain stimulation (tDCS) and cognitive training can help people with alcohol use disorder stay abstinent. You may be included if you are currently not drinking and can commit to the program timeline.
Minneapolis, MinnesotaAges 18–65 - NCT05117255Recruiting
Online therapy study for anxiety in residential alcohol treatment
This study tests an internet-based, interactive version of cognitive behavioral therapy (CBT) for anxiety symptoms. It’s designed for people getting mainly alcohol-focused treatment in a residential program, to see if the online approach works and is feasible for you.
