Recruiting studies
- NCT05565352Enrolling by invitation
Ketamine safety study for people in inpatient psychiatric care
This trial looks at whether ketamine is safe and well-tolerated for certain mental health conditions when given in a hospital setting. It may help teams better understand side effects and comfort for people who may be offered ketamine.
GdanskAges 18–90 - 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 - NCT05437705Recruiting
Brain scan and stimulation study for low mood
This study uses brain imaging (MRI) and a brain-stimulation method (TMS) to understand and possibly change brain patterns linked with low mood. You may be eligible if you have moderate to severe depression symptoms and can safely complete the scans and stimulation sessions.
Philadelphia, PennsylvaniaAges 18–65 - NCT05327699RecruitingEarly Phase 1
Ketamine study for depression with reduced pleasure
This early-phase study tests whether ketamine can help people with major depression who have trouble feeling pleasure. It also studies how the brain may change in response to stress, to better understand who might respond to treatment.
Atlanta, GeorgiaAges 18–65 - NCT05004987RecruitingPhase 4
Study brain and blood changes in older adults with depression
This study looks at how a brain protein linked to Alzheimer’s disease changes over time in older adults who have major depression but no major memory problems. It involves brain scans, blood and urine tests, and a spinal fluid sample to better understand the connection between depression and brain aging.
New York, New YorkAges 60 years+ - NCT04923685Recruiting
Study looks at blood markers linked to childhood trauma and suicide risk
This study checks whether tiny genetic signals in blood (microRNAs) are linked to childhood maltreatment and thoughts or risk of suicide, especially in people with major depression. It may help researchers understand biological clues that could someday guide better care.
Birmingham, AlabamaAges 18–60 - NCT04040062Enrolling by invitation
Tested deep brain–stimulating treatment for hard-to-treat depression
This study tests a specialized type of magnetic brain stimulation (spectral TMS) to treat severe major depression when standard treatments haven’t worked. You may be eligible if you’ve tried several antidepressants and other add-on treatments but still have symptoms.
Los Angeles, CaliforniaAges 18–65 - NCT03953014Recruiting
Genetic study of antidepressant side effects in young people
This trial studies whether genes (using a saliva sample) can help explain why some young people feel more “disinhibited” after taking antidepressants like SSRIs. If you’ve had depression, anxiety, or OCD and have used an SSRI, your information and genetics may help improve how antidepressants are chosen and monitored.
Calgary, AlbertaAges 6–17 - NCT00018057RecruitingPhase 2
Brain study of pediatric anxiety disorders
This study looks at how the brain works in children and adults with anxiety disorders. It uses brain scans (fMRI) and other safe tests to understand anxiety better.
Bethesda, MarylandAges 8–65 - NCT04870255Recruiting
Brain stimulation for depression in borderline personality disorder
This study tests a type of brain stimulation called rTMS to see if it can help improve mood in people who have both depression and borderline personality disorder. It may offer a new treatment option for those who haven't tried TMS before.
Stanford, CaliforniaAges 18–80 - NCT07540585Recruiting
Mental health support for pregnant patients with pregnancy complications
This study tests whether providing mental health care while you're in the hospital for pregnancy-related complications can help you feel better and have better outcomes. It's designed for patients who've had difficulties with past pregnancies.
Indianapolis, IndianaAges 18–100 - 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 - NCT07059234Recruiting
Depression and Activity: The MASE Project
This study tests whether tracking your daily activity can help improve energy and mood in people with depression. You will wear a small device that measures your movement.
BernAges 18–60 - NCT06546917Recruiting
Cognitive training trial for mild depression with brain scans
This trial tests a computer-based cognitive training program (bWell-D) to see if it can improve thinking skills like memory and focus in people with mild depression. You will also have an MRI brain scan to see how the training affects your brain.
Vancouver, British ColumbiaAges 19–55 - NCT05491538Recruiting
Work-focused social skills training for veterans with mental illness
This study tests a program to help veterans with serious mental illness improve social skills for work and find jobs near the VA. It aims to see if the program is acceptable and feasible for participants.
Minneapolis, MinnesotaAges 18 years+ - NCT05232032RecruitingPhase 2
Brain scan and medication study for avoiding versus approaching
This Phase 2 study looks at how a medication affects brain activity and real-life mood or anxiety behaviors. It includes people with major depression or several anxiety disorders and also healthy volunteers, using questionnaires, a smartphone, and brain imaging.
Belmont, MassachusettsAges 18–45 - NCT00762866Enrolling by invitation
Study of mental health traits using genetic and brain measurements
This study collects information about mental health symptoms and body/genetic samples to better understand how different mental health conditions are related. Some people may also have brain scans (PET or MRI) if they can safely complete them.
Nashville, TennesseeAges 16–65 - NCT06338215Recruiting
Moderate drinking vs. abstention advice for adults
This study compares two approaches for adults who drink regularly: advice on drinking in moderation vs. advice to stop drinking entirely. The goal is to see which approach better prevents major diseases and early death over time.
Pamplona, NavarreAges 50–75 - NCT06212219Recruiting
EEG brain training to help arm recovery after stroke
This study tests whether a brain-training technique called neurofeedback can improve arm movement in people who recently had a stroke. It uses an EEG cap to measure your brain activity while you do arm exercises, helping you relearn how to move your affected arm.
ToulouseAges 18–99

Common questions
- Are there clinical trials for major depression?
- Yes. Clin2 currently lists 451 recruiting major depression 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 major depression 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 major depression 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.
