Brain wave and inflammation markers in shock therapy for depression
This study looks at brain wave patterns and markers of inflammation in people with depression that hasn't improved with other treatments and who are receiving electroconvulsive therapy (ECT, also known as shock therapy). The goal is to understand how these markers might relate to how well ECT works.

Phoenix, ArizonaAges 18 years+ - NCT07611773Recruiting
Brain Stimulation for Depression Treatment Planning

You would use a small home device and complete brain monitoring sessions.
ValenciaAges 18 years+ - NCT07603804Recruiting
Accelerated Brain Stimulation for Treatment-Resistant Depression
This study tests an accelerated form of iTBS (a non-invasive brain stimulation technique) for depression that hasn't improved with antidepressant medications. The goal is to help people with major depression who haven't responded adequately to at least one antidepressant drug.
IstanbulAges 18–65 - NCT07572526Recruiting
Brain Stimulation to Improve Sleep and Mood in Depression
This study tests a non-invasive brain stimulation technique called tDCS (transcranial direct current stimulation) to see if improving sleep can help reduce depression symptoms. You'll do short stimulation sessions at home and track your sleep and mood.
New York, New YorkAges 18–65 - NCT07569198RecruitingPhase 2
Ketamine plus therapy for depression with suicidal thoughts
This study tests whether ketamine (a medication) combined with a specific type of therapy called DBT can help people with treatment-resistant depression and borderline personality disorder who are having thoughts of suicide. You would receive ketamine infusions alongside structured therapy sessions over 6 months.
Toronto, OntarioAges 18–70 - NCT06732089Recruiting
Digital help for stubborn depression
This trial tests a digital program (smartphone app or website) to help people with tough-to-treat depression. If you are already receiving advanced treatments like rTMS, ketamine, or ECT at St. Michael's Hospital, you may be able to join and see if this extra digital support improves your mood.
Toronto, OntarioAges 18 years+ - NCT07562191RecruitingPhase 2
Inhaled DMT for major depression
This trial tests if inhaling DMT can help treat moderate to severe major depression. You may qualify if your depression has lasted at least two weeks and you have not changed medications recently.
Fortaleza, CearáAges 18 years+ - NCT07510880Recruiting
Home brain stimulation for major depression
This trial tests a home-based brain stimulation device (tDCS) to treat depression. You would use a headset daily for a few weeks, and the study team will check in to make sure it's working safely and effectively.
L'Hospitalet de Llobregat, BarcelonaAges 18–65 - NCT07512284RecruitingPhase 2
Mindfulness and Brain Stimulation for Treatment-Resistant Depression
This study combines mindfulness practice with transcranial magnetic stimulation (TMS)—a non-invasive brain stimulation technique—to help people with depression that hasn't improved with antidepressant medications. The goal is to see if adding mindfulness to TMS improves how well the treatment works.
San Diego, CaliforniaAges 18–65 - NCT07474974Recruiting
Can Eye Cells Predict TMS Success for Depression?
This study tests whether a specific type of eye cell can predict how well transcranial magnetic stimulation (TMS) works for treating depression. TMS is a non-invasive brain stimulation method that may help people with depression that hasn't responded to other treatments.
Porto, Porto DistrictAges 18–65 - NCT07474363Recruiting
Depression differences between men and women
This study looks at how depression affects men and women differently, including symptoms, strength to cope (resilience), and feelings of stigma. It aims to understand these differences to improve treatment.

Escitalopram for first-time depression
This trial tests whether escitalopram, a common antidepressant, helps people who are experiencing their first episode of depression and have never taken medication for it. It also looks at how the drug works in the brain.
Beijing, Beijing MunicipalityAges 18–65 - NCT07422519Recruiting
Virtual reality mindfulness for hard-to-treat depression
This study tests whether using a virtual reality mindfulness program, added to your usual depression care, can help people whose depression hasn't responded to standard treatments.
BarcelonaAges 18–74 - NCT07282678Recruiting

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.
