HalmstadAges 13–17 - 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 - NCT05142683Recruiting
Test an integrated care plan for teens with depression
This study tests whether a structured, coordinated care pathway helps teens (and their caregivers) manage depression better than usual care. It aims to see if targeted treatment and follow-up improve depression symptoms over time.
Toronto, OntarioAges 13–18 - NCT05194098Recruiting
EEG and brain stimulation study for depression reward symptoms
This study uses non-invasive brain stimulation (like TMS) and EEG brain recordings to measure how the brain’s “reward” system works in people with major depression. It may help researchers understand which stimulation approaches best affect depression-related reward processing.
San Francisco, CaliforniaAges 18–65 - 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 - NCT05239780Recruiting
Brain stimulation study for adults with depression
This study uses an invasive approach (placement of brain monitoring/stimulation) to better understand how the brain processes reward in depression. It may help researchers develop more targeted treatments in the future.
New York, New YorkAges 18–80 - NCT05295888Recruiting
Temporal Interference treatment for moderate-to-severe depression
This study tests temporal interference (TI), a brain stimulation method, to treat depression. You may be a candidate if you have moderate-to-severe major depression and can follow the study schedule and safety screening.
Toronto, OntarioAges 18–65 - NCT05409794Recruiting
Testing blood lithium levels in people with depression and suicidality
This study checks how much lithium is naturally present in the blood and whether that relates to suicidal thoughts or attempts in people with a current major depressive episode. It may help researchers understand biological factors linked to suicide risk and improve future prevention.
MontpellierAges 18 years+ - 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 - NCT05437588Recruiting
Blood-based biomarkers for suicide risk in teens with depression
This study looks at tiny blood particles (exosomes) and specific microRNAs to see if they can signal suicide risk and predict treatment outcomes in adolescents. If you qualify, your blood may be used to help researchers find better ways to understand and track suicidality and depression treatment response.
Birmingham, AlabamaAges 10–24 - 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 - NCT05450432RecruitingPhase 4
Ketamine maintenance to help prevent suicidal thoughts
This Phase 4 study tests whether ongoing treatment with ketamine or esketamine can reduce suicidal thoughts in people with major depression who are at high risk. Because the study focuses on long-term maintenance, you’d receive treatment over time while being closely monitored for safety and mental health changes.
Boston, MassachusettsAges 18–70 - NCT05480150Recruiting
Study of brain and mood in people with depression or bipolar disorder
This study is following and assessing people with major depression or bipolar disorder to better understand the condition and how the brain relates to symptoms. It may help researchers develop more targeted support by comparing brain and health information over time.
