Recruiting studies
- NCT06462196Recruiting
Study of Depression, Bipolar Disorder & Suicide Risk
This study looks at how depression, bipolar disorder, and suicide risk naturally change over time. It aims to better understand these conditions so doctors can improve treatments.
Bethesda, MarylandAges 18–120 - 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 - 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 - 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 - 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 - NCT04509102Enrolling by invitationEarly Phase 1
Test added stimulant medicine with rTMS for depression
This early study tests whether adding a stimulant medicine to repetitive TMS (a non-drug brain stimulation) can improve depression. It is aimed at people whose depression has not improved after at least two antidepressant tries.
Los Angeles, CaliforniaAges 18–65 - NCT04556890Recruiting
Brain stimulation for treatment-resistant depression and chronic pain
This study tests a non-invasive brain stimulation treatment, called transcranial magnetic stimulation (TMS), to see if it can help people who have both major depression that hasn't improved with medication and chronic pain from fibromyalgia or chronic fatigue syndrome. It aims to reduce both depression and pain symptoms.
Los Angeles, CaliforniaAges 18–75 - NCT06417437RecruitingPhase 4
Brain-computer interface test for depression
This trial tests a non-invasive brain-computer interface (BCI) to help people with depression. It may be a good fit for teenagers and adults who are right-handed, Han Chinese, and have moderate to severe depression without other major health problems.
Shanghai, Shanghai MunicipalityAges 12 years+ - NCT06542094Recruiting
Brain stimulation for severe depression that hasn't improved with other treatments
This trial tests if deep brain stimulation (a device that sends tiny electrical pulses to mood-related brain areas) can help people with tough-to-treat depression. It uses brain-signal monitoring to see which patterns predict improvement.
Chengdu, SichuanAges 18–65 - NCT07284667RecruitingPhase 2
A new medicine for depression that hasn't improved with other treatments
This trial tests a new medicine called ACP-211 in adults with major depression who have not gotten enough relief from at least two previous antidepressants. The goal is to see if it can help when other treatments have not worked well.
Birmingham, AlabamaAges 18–65 - NCT07212075Recruiting
Digital twin study for mental health in diabetes
This study uses digital twins—a virtual model of your health—to track how your mental health changes with diabetes. It aims to find patterns that could help personalize mental health care.
Bad Mergentheim, Baden-WurttembergAges 18–80 - NCT06860165Recruiting
Mood tracking app study for adults with depression
This study tests a smartphone app (EmoDTx) that monitors mood in people with unipolar depression. It aims to see if the app can provide helpful digital measurements of your mood.
Changé, FranceAges 18 years+ - NCT03537794Recruiting
Brain scan study in treatment-resistant depression
This study compares brain synaptic density in people with treatment-resistant depression, people with depression that responds to treatment, and healthy controls. It uses a PET scan to measure synaptic density and aims to understand the biological differences.
Toronto, OntarioAges 25–65 - NCT07775300RecruitingPhase 3
Study of an injectable drug for major depressive disorder
This study tests an investigational drug called brenipatide for major depressive disorder. It is given as a self-injection and is being compared to a placebo to see if it helps improve depression symptoms in people who are already on standard treatment.
Birmingham, AlabamaAges 18–75 - NCT07684911Recruiting
Long-term effects of TMS for depression
This study looks at how well the benefits of transcranial magnetic stimulation (TMS) last over time for people with depression that didn't get better with other treatments. It also uses brain scans to find markers that might predict who will keep doing well.
RennesAges 18 years+ - NCT07592689RecruitingPhase 3
DT120 Treatment for Major Depression
This study tests whether a new medication called DT120 can help people with moderate-to-severe depression feel better. You'd take the medication for several weeks while doctors track your mood and symptoms.
Little Rock, ArkansasAges 18–74 - NCT07573176RecruitingPhase 3
Seltorexant for Depression in Adults and Older Adults
This study tests a new medication called seltorexant as a standalone treatment for major depression. The trial is for adults and older adults who have depression that hasn't improved with other antidepressants or who haven't tried them yet.
Bryant, ArkansasAges 18–74 - NCT07462637Recruiting
Light therapy for depression in unipolar and bipolar disorder
This study tests how well light therapy works for moderate to severe depression in people with or without bipolar disorder. It includes a possible MRI brain scan to understand how light affects the brain. You must not have certain eye conditions or high suicide risk.
ParisAges 18–65 - NCT07412756RecruitingPhase 3
Brenipatide for major depressive disorder
This trial tests a new medication, Brenipatide, to see if it helps people with major depression who are already on a stable treatment. You would need to inject the study drug yourself and complete questionnaires.
Moorpark, CaliforniaAges 18–75 - NCT07228468Recruiting
Home brain stimulation for depression
This trial tests if a gentle electrical current applied to the head at home can help reduce symptoms of major depression. You would use a device for short sessions over several weeks, while continuing your usual care.
CardiffAges 18 years+ - NCT07227454RecruitingPhase 3
Esketamine for teens with severe depression and suicidal thoughts
This trial tests if esketamine (a nasal spray) can quickly reduce symptoms of major depression and suicidal thoughts in teenagers who need urgent hospital care.
Birmingham, AlabamaAges 12–17 - NCT07196501RecruitingPhase 3
Study of a new add-on treatment for depression maintenance
This trial tests a new medication (NBI-1065845) added to your current antidepressant to see if it helps maintain improvement in depression. It is for people whose depression hasn't fully responded to their current oral antidepressant.
Oceanside, CaliforniaAges 18 years+ - NCT07113548Recruiting
Personalized online treatment for depression
This trial tests an online program tailored to your needs for treating depression. You'll get a personalized treatment plan that you can access from your smartphone, without needing to visit a clinic.
OdenseAges 18 years+ - NCT06966401RecruitingPhase 3
Long-term safety study of a new depression treatment
This study tests a new oral medication (NBI-1065845) added to your current antidepressant to see if it's safe and tolerable over a long period for people with depression that hasn't fully responded to treatment.
Huntsville, AlabamaAges 18 years+
