Toronto, OntarioAges 60 years+ - NCT06832605Recruiting
Mindfulness classes by video to prevent depression relapse
This trial tests an 8-week mindfulness-based cognitive therapy program delivered via video call to help people with a history of depression prevent future episodes. It may help you learn skills to manage low mood and reduce the chance of relapse.

Study of an experimental psychedelic-like drug for depression (CYB003)
This study tests an investigational medication (CYB003) for people with major depression whose current antidepressant isn't working well enough. It looks at whether this treatment can help improve depression symptoms.
Birmingham, AlabamaAges 18–85 - NCT06692361Recruiting
Gut bacteria transplant for depression not helped by escitalopram
This trial tests whether transplanting healthy gut bacteria (fecal microbiota) can help people with depression that does not respond well to the antidepressant escitalopram. You will first take escitalopram for 2 weeks, and if it doesn't help enough, you may receive either the real transplant or a placebo capsule.
Wuhu, AnhuiAges 18–65 - NCT06619366Recruiting
Guided risk talk to prevent major depression
This study tests if talking with a coach about your personal risk of depression can help prevent it. You may be eligible if you are at higher risk but currently well.
Halifax, Nova ScotiaAges 18–65 - NCT06580041Enrolling by invitationPhase 4
Precision treatment for major depression
This trial tests a personalized approach to treating major depressive disorder using assessments and brain imaging to match you with the best therapy. It aims to improve outcomes by tailoring care to your specific needs.
San Francisco, CaliforniaAges 18 years+ - NCT06523439Recruiting
Brain stimulation for depression in young people
This study tests a new type of brain stimulation called accelerated intermittent theta burst stimulation (aiTBS) in young people (ages 13-20) with depression who have not tried many treatments before. The goal is to see if this treatment can safely help reduce depression symptoms.
Austin, TexasAges 13–20 - NCT06396312Recruiting
Predicting lithium response in difficult depression
This study looks at how to predict which people with hard-to-treat depression will benefit from adding lithium to their antidepressant. If you have treatment-resistant depression and are considering lithium, this trial may help find the best treatment for you.
Munich, BavariaAges 18 years+ - NCT05630963Recruiting
Study sleep-like brain signaling in major depression
This trial looks at how a specific brain receptor related to pain signals (nociceptin/orphanin FQ receptor) may be involved in depression. It may help researchers understand depression better by comparing people with current versus past (remitted) major depression.
Belmont, MassachusettsAges 18–45 - NCT06086366Recruiting
Brain scan study for depression after COVID-19
This study uses brain scans to understand depression that starts soon after COVID-19. Researchers want to see if there are changes in brain chemistry related to depression, and you may help find new treatment targets.
Toronto, OntarioAges 18–75 - NCT05892744RecruitingPhase 4
Testing brain scans to help choose depression treatment
This trial studies how brain signals measured by MRI and EEG may help doctors choose the best treatment for depression. It focuses on people with early-onset, long-lasting or recurring major depression, and tests whether these “brain biomarkers” track with treatment choice and response.
Austin, TexasAges 18–65 - NCT04999553Recruiting
Comparing brain stimulation on left vs right side for depression
This study tests whether delivering a type of brain stimulation to the left side of the head is as effective as delivering it to the right side for treating major depression. The treatment is called transcranial magnetic stimulation (TMS), which uses magnetic pulses to stimulate brain areas involved in mood.
Vancouver, British ColumbiaAges 18–65 - NCT04480918Recruiting
Registry for people with depression or bipolar to receive psychiatry care
This is a patient registry that enrolls people being evaluated for treatment options from an Interventional Psychiatry Service. It helps track patients with depression, bipolar disorder, or treatment-resistant OCD who are suitable for these psychiatry treatments.
Iowa City, IowaAges 18–99 - NCT03973268RecruitingPhase 1
Ketamine study to understand treatment response in hard-to-treat depression
This early-stage study tests ketamine and looks at what brain changes may explain why it helps people with major depression that hasn’t improved with usual treatments. You may be asked to stay in the hospital and complete detailed interviews, mood rating scales, and brain imaging.
Bethesda, MarylandAges 18–70 - NCT04004169Recruiting
Closed-loop deep brain stimulation for long-lasting depression
This study tests a special kind of brain stimulation that can adjust to your brain signals while treating major depression that has not improved with standard treatments. It may help people with severe, long-term treatment-resistant depression, but it requires brain surgery and frequent visits.
San Francisco, CaliforniaAges 22–70 - NCT03065335RecruitingPhase 1
Ketamine plus brain imaging to study response in depression
This early-stage study tests how ketamine given once and then repeatedly may change brain signals and related biomarkers in people with major depression. If you’re eligible, the team will use brain imaging and assessments to see who responds and why.
Bethesda, MarylandAges 18–65 - NCT06409325Recruiting
Magnetic Seizure vs. Electric Shock for Depression
This study compares two brain stimulation treatments—Magnetic Seizure Therapy (MST) and Electroconvulsive Therapy (ECT)—to see which works better for severe depression. If you are on a stable antidepressant and haven't had recent brain stimulation, this trial may be an option for you.
Shanghai, Shanghai MunicipalityAges 18–65 - NCT07768397Recruiting
Comparing two brain-stimulation schedules for depression
This study tests two different schedules of a treatment called theta burst stimulation, which uses magnetic pulses to gently stimulate the brain. It aims to find out if the faster schedule works better than the standard one for people with major depression.
Ho Chi Minh CityAges 18–65 - NCT05644301RecruitingPhase 3
Blood-marker guided add-on treatment for major depression
This study tests whether doctors can choose the best add-on immune-related treatment for people with major depressive disorder by using inflammation blood tests. It’s meant for people whose depression has not improved enough with their current antidepressant.
Duffel, AntwerpenAges 18–65 - NCT07691749Recruiting
Psychobiotics plus antidepressants for Major Depression
This study tests whether adding psychobiotics (special probiotics for mental health) to your current antidepressant helps treat major depression better than the antidepressant alone. It may be an option if you have moderate to severe depression and are on a stable antidepressant dose.

- 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.
