Recruiting studies
- NCT06781905Recruiting
Brain effects of ALK/ROS1 lung cancer drugs and quality of life
This study looks at how certain targeted therapy drugs for ALK/ROS1-positive lung cancer may affect thinking, memory, mood, and mental health. It aims to build a special care and research path where patients and researchers work together to understand and manage these side effects.
BronAges 18 years+ - NCT05877885Recruiting
Digital treatment for low motivation in older adults with depression
This study tests a digital therapy to improve apathy (feeling unmotivated or “checked out”) in people age 60+ who have depression. It also uses brain imaging (MRI) and questionnaires to see whether the treatment helps brain function linked to motivation.
Orlando, FloridaAges 60 years+ - NCT06853665RecruitingPhase 4
Study of mixed amphetamine for autism and ADHD in teens
This trial tests if a mixed amphetamine medication helps teenagers with both autism and ADHD who still have significant symptoms, even if they are already on other treatments. It also includes typically developing teens as a comparison group.
Boston, MassachusettsAges 8–18 - NCT04956016Recruiting
Compare two rTMS treatments for moderate to severe depression
This study tests whether a classic type of brain stimulation (rTMS) works better or the same as a deeper version for depression that keeps coming back or is ongoing. You may be offered one of the two stimulation options to see which helps reduce depressive symptoms.
PoitiersAges 18 years+ - NCT07083557Recruiting
Validation study for lab tests on hormones and metabolism
This study checks if lab tests used for hormone, heart, metabolism, and muscle disorders are accurate and reliable. You might be eligible if you are an adult with a body mass index between 16 and 60.
Columbia, MissouriAges 18–100 - NCT06639438Recruiting
Sensory outcomes in people who use opioids
This study looks at how opioids affect the senses in people having planned surgery. Researchers want to compare patients who use opioids (for pain or addiction) with those who don't, to see if there are differences in sensation.
Boston, MassachusettsAges 18 years+ - NCT07533773Recruiting
Brain Activity Changes After Depression Treatment
This study measures how brain activity in specific regions changes after you receive electroconvulsive therapy (ECT) or magnetic seizure therapy (MST) for severe depression. Researchers use a non-invasive headband to monitor blood flow in your brain before and after treatment to better understand how these therapies work.
Hefei, AnhuiAges 12–65 - NCT06373016Recruiting
Ketone drink study for stable bipolar disorder
This study tests whether a ketone drink can change how the body uses energy in people with bipolar disorder. It may help understand new ways to manage the condition.
Belmont, MassachusettsAges 18–45 - NCT05929144Recruiting
MRI testing to improve brain scans in neurodegenerative diseases
This study aims to improve MRI scan settings used when studying brain diseases that affect memory and movement. You would be asked to undergo MRI scanning as a healthy volunteer to help optimize the imaging process.
CaenAges 18 years+ - NCT07263321Recruiting
Depression treatment choice in general practice
This study helps people with moderate depression decide between medication and therapy. Your doctor will work with you to pick the best option.
AalborgAges 18–65 - NCT06544226Recruiting
Using smart devices to track eating disorder recovery
This study tests whether smart devices can help monitor recovery in people with eating disorders. You will use a device to track health signs and attend weekly clinic visits.
LiverpoolAges 10 years+ - NCT06821646Enrolling by invitation
Brain responses in depression and autism with TMS and EEG
This study uses brain stimulation (TMS) and brain wave recording (EEG) to understand how the brain works in people with autism, depression, or both. It may help find better ways to treat these conditions.
TaipeiAges 20–50 - NCT07469384Recruiting
Brain stimulation study for schizophrenia using tDCS
This study tests whether a mild form of brain stimulation called tDCS (transcranial direct current stimulation) can help improve symptoms of schizophrenia or schizoaffective disorder. tDCS uses small electrodes on the scalp to gently stimulate brain areas involved in vision and thinking.
Orangeburg, New YorkAges 18–55 - 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+ - 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 - 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 - 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 - 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 - 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 - 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).

Common questions
- Are there clinical trials for substance use disorders?
- Yes. Clin2 currently lists 409 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.
