Observing ketamine and Spravato for depression
This study follows people who are already taking or about to start IV ketamine or Spravato® for hard-to-treat depression. Researchers want to learn more about how these treatments work in real life.
Milford, ConnecticutAges Any age - NCT06605105Enrolling by invitationPhase 3
Long-term extension trial of CYB003 for depression
This long-term study is for people who already completed an earlier trial of the experimental drug CYB003 for major depression and who stayed on their regular antidepressant. It looks at the safety and effects of taking CYB003 again over many months.
Phoenix, ArizonaAges 18–85 - NCT06546917Recruiting
Cognitive training trial for mild depression with brain scans
This trial tests a computer-based cognitive training program (bWell-D) to see if it can improve thinking skills like memory and focus in people with mild depression. You will also have an MRI brain scan to see how the training affects your brain.
Vancouver, British ColumbiaAges 19–55 - NCT05645575Recruiting
Inpatient TMS for treatment-resistant depression
This study tests an in-hospital brain stimulation treatment (TMS) for people with moderate to severe depression who did not improve after multiple antidepressant treatments. It may help your mood by targeting brain circuits involved in depression, and you would follow an intensive accelerated schedule.
Los Angeles, CaliforniaAges 18–65 - NCT06183359Recruiting
Self-Identification Program for Depression
This study tests a self-identification program for people aged 18 to 70 who are currently in a major depressive episode. It aims to explore whether a simple self-monitoring tool can help you better manage your depression.
MontpellierAges 18–70 - NCT05996900Recruiting
Brain stimulation study for adults with epilepsy
This study uses advanced brain monitoring and noninvasive magnetic stimulation to understand how repetitive brain stimulation works in people with epilepsy who are already scheduled for hospital monitoring. It may help develop better treatments for seizures.
Stanford, CaliforniaAges 18–65 - NCT05703412Enrolling by invitation
Text or app check-ins after discharge for serious mental illness
This study tests an mHealth (phone-based) program that helps people with serious mental illness after leaving the hospital. It may help you stay connected to care and support in the community after discharge.
Providence, Rhode IslandAges 18 years+ - NCT05613972Recruiting
Combined therapy for adults with suicidal thoughts and childhood trauma
This study tests a new combination of talk therapies for adults who have both suicidal thoughts and a history of childhood trauma. The goal is to see if this combined approach reduces suicide risk better than usual care.
Toronto, OntarioAges 18 years+ - NCT05437705Recruiting
Brain scan and stimulation study for low mood
This study uses brain imaging (MRI) and a brain-stimulation method (TMS) to understand and possibly change brain patterns linked with low mood. You may be eligible if you have moderate to severe depression symptoms and can safely complete the scans and stimulation sessions.
Philadelphia, PennsylvaniaAges 18–65 - NCT05327699RecruitingEarly Phase 1
Ketamine study for depression with reduced pleasure
This early-phase study tests whether ketamine can help people with major depression who have trouble feeling pleasure. It also studies how the brain may change in response to stress, to better understand who might respond to treatment.
Atlanta, GeorgiaAges 18–65 - NCT05004987RecruitingPhase 4
Study brain and blood changes in older adults with depression
This study looks at how a brain protein linked to Alzheimer’s disease changes over time in older adults who have major depression but no major memory problems. It involves brain scans, blood and urine tests, and a spinal fluid sample to better understand the connection between depression and brain aging.
New York, New YorkAges 60 years+ - NCT04923685Recruiting
Study looks at blood markers linked to childhood trauma and suicide risk
This study checks whether tiny genetic signals in blood (microRNAs) are linked to childhood maltreatment and thoughts or risk of suicide, especially in people with major depression. It may help researchers understand biological clues that could someday guide better care.
Birmingham, AlabamaAges 18–60 - NCT04040062Enrolling by invitation
Tested deep brain–stimulating treatment for hard-to-treat depression
This study tests a specialized type of magnetic brain stimulation (spectral TMS) to treat severe major depression when standard treatments haven’t worked. You may be eligible if you’ve tried several antidepressants and other add-on treatments but still have symptoms.
Los Angeles, CaliforniaAges 18–65 - NCT07878754RecruitingPhase 1
Remote monitoring for depression treatment
This study tests whether remote monitoring through a smartphone, computer, or tablet can help people with depression who are starting a new antidepressant. It aims to see if this approach improves care and outcomes.

Can Avnace eZZe improve sleep?
This study tests a dietary supplement called Avnace eZZe to see if it helps improve sleep in adults with insomnia. You may be able to join if you have a diagnosis of insomnia and are not currently using sleep aids.
TaipeiAges 18 years+ - NCT07813169Recruiting
Brain stimulation for loss of pleasure in depression
This study tests a type of brain stimulation called iTBS (repetitive magnetic pulses) to see if it can help people with depression who feel little pleasure in life. The treatment targets a brain area involved in reward, and may improve your mood and ability to enjoy things.
Changsha, HunanAges 18–45 - NCT06923995Recruiting
AI-based depression and anxiety assessment study
