Recruiting studies
- NCT06048172Recruiting
Trauma therapy for PTSD with a psychotic disorder
This trial tests if prolonged exposure therapy, a common PTSD treatment, can help people who also have a psychotic disorder (like schizophrenia or bipolar with psychosis). The goal is to reduce PTSD symptoms.
HamburgAges 18 years+ - NCT06638710RecruitingPhase 2
Testing oral midazolam for care in elderly with dementia who refuse care
This trial tests if giving a medication called midazolam by mouth can help older adults with memory problems who refuse care to accept it more calmly. It is for people in certain hospital or long-term care units, with moderate to severe memory loss and a history of resisting care.
Grenoble, IsereAges 60 years+ - NCT07763392Recruiting
Normal cognitive test scores for adults
This study is testing a voice-controlled digital platform to measure normal memory and thinking abilities in healthy adults. By participating, you would help create a baseline of normal scores that doctors can use to compare against when assessing people with thinking problems.
Carlsbad, CaliforniaAges 18–100 - NCT07750639Enrolling by invitationPhase 4
Reducing painkiller use after hand surgery
This study tests a new approach to prescribing fewer opioid pain pills after hand, wrist, or elbow surgery. It aims to help reduce the risk of opioid misuse while still controlling pain after surgery.
Orlando, FloridaAges 18 years+ - NCT05343598Recruiting
Using TMS to study hallucinations in schizophrenia
This study uses a non-invasive brain stimulation method (TMS) along with brain scans (MRI) to better understand why hallucinations happen in schizophrenia. It may help researchers learn more about brain processes involved, which could guide future treatments.
Belmont, MassachusettsAges 18–55 - NCT07197138Recruiting
TMS for depression with long COVID
This trial tests whether accelerated TMS (a brain stimulation treatment) can help people with depression who also have long COVID. It may be an option if your depression hasn't improved enough with medication alone.
Munich, BavariaAges 18–65 - NCT06274112Recruiting
Using brain stimulation to understand social motivation in depression or social anxiety
This study uses transcranial magnetic stimulation (TMS), a non-invasive brain stimulation technique, to explore how the brain processes social motivation in people with major depressive disorder or social anxiety disorder. Understanding these brain processes could help develop new treatments for social avoidance.
Auburn, AlabamaAges 25–50 - NCT05205291Recruiting
Imaging inflammation in Parkinson’s using PET/MR scans
This study uses special brain scans (PET/MR) to see inflammation in people with Parkinson’s disease or related conditions. It may help researchers better understand what drives symptoms and how inflammation changes in the brain.
ExeterAges 50–85 - NCT07345377Enrolling by invitation
Personalized brain stimulation for irritable bowel syndrome
This study uses brain stimulation (TMS) customized for each person to treat IBS. It uses MRI scans to see how the brain responds, aiming to find better ways to predict who will benefit from this therapy.
Hangzhou, ZhejiangAges 18–75 - NCT05194098Recruiting
EEG and brain stimulation study for depression reward symptoms
This study uses non-invasive brain stimulation (like TMS) and EEG brain recordings to measure how the brain’s “reward” system works in people with major depression. It may help researchers understand which stimulation approaches best affect depression-related reward processing.
San Francisco, CaliforniaAges 18–65 - NCT04883411Recruiting
First-in-human test of new cervical spine plate and cage
This study tests a new implanted metal plate and cage to treat problems in the neck caused by worn spinal discs and nerve or spinal cord compression. It is aimed at people whose symptoms have not improved with non-surgical care for at least 6 weeks (or who have worsening nerve/spinal cord symptoms).
Union, New JerseyAges 22–79 - NCT07157540Enrolling by invitation
Testing Cann'App for cannabis harm reduction
This study is testing a smartphone app called Cann'App to help people who use cannabis reduce related harms. It's only for people who are already in a larger cannabis study in Lausanne, Switzerland.
Lausanne, Vaud CantonAges 18 years+ - NCT07354139Recruiting
Can brain stimulation help adults who stutter speak more fluently?
This study uses a gentle, non-invasive brain stimulation technique to see if it can reduce speech errors in adults who have stuttered since childhood. If you are 22 or older, speak English as your main language, and have developmental stuttering, you may be able to join.
Richardson, TexasAges 22 years+

Common questions
- Are there clinical trials for substance use disorders?
- Yes. Clin2 currently lists 421 recruiting substance use disorders studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a substance use disorders trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a substance use disorders trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
