Baltimore, MarylandAges 25–55 - NCT05677321Recruiting
Study how taste and smell differ in alcohol use disorder
This study compares how people with alcohol use disorder and people without it experience taste and smell. It also checks brain activity during taste/smell testing to understand individual differences that may be linked to alcohol use.
Bethesda, MarylandAges 18–65 - NCT05042102RecruitingPhase 2
Donepezil plus brain training for alcohol use disorder
This Phase 2 study tests whether donepezil, along with structured cognitive (brain) training, can improve outcomes for people with alcohol use disorder. It will measure whether this combination helps after recent heavy drinking, while tracking safety over about 13 weeks.
West Haven, ConnecticutAges 18–80 - NCT04354077Recruiting
Deep brain stimulation for opioid addiction
This study tests whether deep brain stimulation (DBS), a surgical treatment that uses electrical pulses to target specific brain areas, can help reduce cravings and relapse in people with opioid use disorder who haven't found relief from other treatments.
Pittsburgh, PennsylvaniaAges 22–65 - NCT06967831Recruiting
Testing existing drugs for mitochondrial disorders
This trial looks at whether drugs already approved for other conditions might help people with Leigh syndrome, a rare mitochondrial disorder. Researchers will study cells made from your skin to see how these drugs work.
Düsseldorf, North Rhine-WestphaliaAges Any age - NCT06923423Recruiting
Cognitive processing therapy for drug use and trauma in prison
This study tests if a type of therapy called cognitive processing therapy (CPT) can help people in prison who have both a drug use problem and trauma-related stress. If you qualify, you would receive CPT and be compared to those getting usual care.
Little Rock, ArkansasAges 18 years+ - NCT06969937RecruitingPhase 2
Ketamine and Neurofeedback for Alcohol Use Disorder
This study tests whether combining ketamine with a brain-training technique called neurofeedback can help people reduce or stop drinking alcohol. It may offer a new treatment option for alcohol use disorder.
ZurichAges 18–65 - NCT06800703Recruiting
Opioid use, pain, and the brain
This study uses brain scans (MRI) to understand how pain affects people with opioid use disorder or regular opioid use, compared to healthy volunteers. It aims to find better ways to treat both pain and opioid addiction.
New Haven, ConnecticutAges 21–60 - NCT05913752RecruitingPhase 1/Phase 2
Test drug CMND-100 in people with alcohol use disorder
This early study tests the safety and dosing of CMND-100 in first-time participants, including people with alcohol use disorder (AUD) and some healthy volunteers. It may help researchers understand whether the drug is safe, and how it might affect alcohol use in AUD.
New Haven, ConnecticutAges 18–60 - NCT04616781RecruitingPhase 2/Phase 3
Ketone drink study for alcohol use disorder brain function
This study tests whether a ketone-based treatment (a ketone ester) can change brain activity in people with alcohol use disorder who are not currently seeking treatment. You may also have brain scans, so the study is looking for safe MRI eligibility and certain health factors.
Philadelphia, PennsylvaniaAges 21–65 - NCT07387796Recruiting
Brain and behavior changes with tirzepatide stop and restart
This study looks at how your brain and behavior change when you stop and then restart the weight loss drug tirzepatide. It will help researchers understand what happens during treatment breaks.
Dallas, TexasAges 18–70 - NCT05534815Recruiting
