- 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 - NCT04161066RecruitingPhase 1
Psilocybin plus buprenorphine to help opioid use disorder symptoms
This Phase 1 study tests how adding psilocybin to a standard opioid treatment (buprenorphine-naloxone) affects recovery and symptoms in people with moderate-to-severe opioid use disorder. It may help researchers understand whether this combination is safe and beneficial alongside medication for opioid withdrawal and cravings.
Madison, WisconsinAges 21–65 - NCT06405607RecruitingPhase 2
Psilocybin vs Ketamine for Alcohol Use Disorder Trial
This trial tests two psychedelic-assisted therapies, psilocybin and ketamine, to see which works better for reducing heavy drinking in people with alcohol use disorder (AUD). You'll receive either drug along with counseling, and the study monitors safety closely.
Iowa City, IowaAges 21–65 - NCT06995885Enrolling by invitation
A study to improve tracking of opioid use in the fentanyl era
This study aims to develop a better tool for recalling and tracking opioid use patterns, especially with fentanyl. It may help people who use opioids outside of medical settings to more accurately report their use.
Baltimore, MarylandAges 18–99 - NCT06484075RecruitingPhase 1/Phase 2
Sleep medication for alcohol use disorder
This study tests whether suvorexant, a sleep aid, can help people with alcohol use disorder by looking at brain changes. It may improve sleep and reduce drinking.
Bethesda, MarylandAges 18–75 - NCT05658796Recruiting
Program to reduce opioid use after hip or knee replacement
This trial tests a support program called RXWell to help people use less opioid pain medicine after elective hip or knee replacement surgery. It may help by addressing anxiety and depression symptoms that can affect pain and recovery.
Monroeville, PennsylvaniaAges 18–100 - NCT05630781Recruiting
Orexin's role in the neurobiology of addiction
This study looks at how a brain chemical called orexin affects addiction. Researchers will give a medication that blocks orexin to see if it helps reduce cravings or use. It might help people who smoke or vape regularly.
Baltimore, MarylandAges 18–60 - NCT06780202RecruitingPhase 2
Steroid to reduce opioid use after foot/ankle surgery
This study tests whether a steroid medicine called Medrol Dosepak can help reduce the need for opioid painkillers after foot or ankle surgery. If you are having foot or ankle surgery at Emory and are generally healthy, you may be able to join.
Atlanta, GeorgiaAges 18–95 - NCT05538910Recruiting
Brain imaging study on substance use and depression
This study uses brain scans to understand how substance use and mental illness, like depression, are linked. It may help develop better treatments by looking at brain activity in people with and without depression.
Baltimore, MarylandAges 18–60 - NCT07559500RecruitingPhase 1
Study of tirzepatide for alcohol use disorder
This trial tests if tirzepatide, a diabetes drug, affects brain chemistry linked to alcohol use. Researchers want to see if it can help people with mild-to-moderate alcohol use disorder who also have tried stimulants.
Bethesda, MarylandAges 21–65 - NCT07813026RecruitingPhase 4
Combining gabapentin and oxycodone: abuse effects in recreational users
This study looks at how the combination of gabapentin and oxycodone affects feelings of reward or abuse (like euphoria) in healthy people who have used opioids recreationally. It helps understand if this combination might be more or less abusable.
