Phoenix, ArizonaAges 18 years+ - NCT05850689RecruitingPhase 3
Lumateperone add-on for major depression that didn’t improve
This study tests whether adding lumateperone to an antidepressant helps adults with major depressive disorder (MDD) who haven’t improved enough after trying at least two different antidepressants. It may help reduce depressive symptoms more than antidepressants alone.
Huntsville, AlabamaAges 18–65 - NCT07180537Recruiting
Health course for joint and mood conditions
This study tests an online health course that helps improve diet and self-care to support cell health and wellbeing. It is for people with certain rheumatological conditions like rheumatoid arthritis, lupus, or psoriatic arthritis, who also have mood concerns.
Iowa City, IowaAges 18–100 - NCT06247839RecruitingPhase 3
Psilocybin for depression: changing self-focus
This trial tests whether a single dose of psilocybin can help people with treatment-resistant depression by changing how they focus on themselves. It aims to understand how psilocybin affects brain activity and self-related thinking.
Charlestown, MassachusettsAges 18–55 - NCT02994433RecruitingPhase 1
Testing nitrous oxide for depression brain circuit activity
This early study tests whether nitrous oxide, aimed at specific brain circuits, can change depression-related brain activity. It is mainly for adults with major depression or treatment-resistant depression, and includes brain imaging during the study.
St Louis, MissouriAges 18–65 - NCT04637620RecruitingPhase 2
NMDA-based treatment study for major depression
This Phase 2 trial tests whether an NMDA-targeted treatment can improve symptoms of major depressive disorder (MDD). You may be able to join if your depression diagnosis and symptom score fit, and you meet several safety and study-following requirements.
TaichungAges 18–55 - NCT04751331RecruitingPhase 1/Phase 2
Study brain response to inflammation in depression
This early-stage study tests how your brain responds to an “inflammatory challenge” in people with major depressive disorder and in healthy volunteers. It may help researchers understand the immune-to-brain link in depression and guide future treatments.
Tulsa, OklahomaAges 18–65 - NCT05136755RecruitingPhase 2
NMDA treatment for depression that did not improve
This trial studies an NMDA-based treatment for people with major depressive disorder who did not respond to at least one antidepressant. It may help by changing brain signaling linked to depression symptoms.
TaichungAges 18–65 - NCT05435222Recruiting
Male-only therapy program for major depression
This study tests a counseling/psychotherapy program designed specifically for men with major depression. If you qualify, you may be offered this structured therapy and followed to see whether it helps depressive symptoms.
Zurich, Canton of ZurichAges 25–50 - NCT05441969Recruiting
Brain stimulation study for major depression symptoms
This trial studies a way to change how excitable the brain is (through in-person brain stimulation) in people with major depression. It may help understand new treatments or symptom patterns that could be useful for major depression.
LisbonAges 18–65 - NCT05549102Recruiting
CBT therapy study for anxiety and brain circuit changes
This trial studies whether a specific form of talk therapy (CBT) changes brain activity in people with moderate anxiety. It may help your care team understand what works best and how brain “circuits” respond to treatment.
LondonAges 18–64 - 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 - NCT06132178RecruitingPhase 2
Psilocybin and rTMS for hard-to-treat depression
This study tests whether a combination of psilocybin (a psychedelic substance) and transcranial magnetic stimulation (rTMS, a noninvasive brain stimulation) can help people with treatment-resistant depression. It involves daily visits to the research center for about 2 weeks.
Austin, TexasAges 22–65 - NCT06152705Recruiting
fMRI-Guided vs. Standard Brain Stimulation for Depression
This study compares two types of repetitive transcranial magnetic stimulation (rTMS) to treat depression. One type uses a brain scan (fMRI) to guide the treatment, while the other uses a standard approach. It may help people whose depression hasn't improved with medication.
Ottawa, OntarioAges 18 years+ - NCT06450704Recruiting
Exercise for depression: brain and body health
This trial tests if a 12-week exercise program can reduce inflammation and improve brain function in people with depression. It's for adults currently taking antidepressant medication and looking for extra help through physical activity.
Alcalá de Henares, MadridAges 18–65 - NCT06547489RecruitingPhase 2
Testing zelquistinel for major depression
This study tests whether zelquistinel, an investigational drug, can reduce symptoms of major depressive disorder (a type of clinical depression). It is for people who are currently experiencing a moderate to severe depressive episode and are not taking other antidepressants.
Birmingham, AlabamaAges 18–64 - NCT06592833RecruitingPhase 2
Psilocybin with or without pimavanserin for depression
This study tests whether combining psilocybin (a psychedelic substance) with pimavanserin (a medication that may help reduce side effects) works better than psilocybin alone for treating major depressive disorder. It may help people who have not responded well to other treatments.
New York, New YorkAges 21–80 - NCT06668688Recruiting
Testing a school mental health website
This study looks at how users naturally interact with a website called 'ich Bin Alles @Schule' (I Am Everything @school). It aims to understand the user experience, which may help improve the site for students.
MunichAges Any age - NCT06695767Recruiting

- Are there clinical trials for depressive disorder?
- Yes. Clin2 currently lists 689 recruiting depressive disorder 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 depressive disorder 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 depressive disorder 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.
