Recruiting studies
- 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 - NCT05296356RecruitingPhase 2
Study drug for bipolar depression in people already on mood stabilizers
This trial tests whether OSU6162 can improve depressive symptoms in adults with bipolar depression who are already taking a stable mood-stabilizing medicine. It also checks safety by closely monitoring mood, heart rhythm, and other health factors during the study.
GothenburgAges 18–65 - 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 - NCT05867849RecruitingPhase 3
Cannabidiol treatment for bipolar depression symptoms
This trial tests whether cannabidiol (CBD) can reduce symptoms of bipolar depression. You may be eligible if you have bipolar I or II and a current depressive episode while staying on approved mood-stabilizing or antipsychotic medication.
Vancouver, British ColumbiaAges 19–70 - NCT05913947RecruitingPhase 4
Lithium or cariprazine for bipolar depression
This trial compares lithium versus cariprazine to treat an episode of depression in people with bipolar disorder. It may help find which medicine works better and is safer during the acute (active) phase of depression.
AalborgAges 18–65 - NCT06081426Recruiting
Ketogenic diet for bipolar disorder brain study
This study looks at how a ketogenic diet (very low carb, high fat) might affect brain function in people with bipolar disorder. Participants will follow the diet and have brain scans and blood tests to see how it helps mood and energy levels.
Pittsburgh, PennsylvaniaAges 18–40 - 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+ - 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 - NCT06641726Recruiting
Global database linking genetics and health records for mental illness
This trial is building a research database that combines genetic information and long-term health data to improve personalized treatment for serious mental illness. You may be eligible if you have been diagnosed or treated for depression, bipolar disorder, schizophrenia, or dementia.
Oxford, OxfordAges 18–110 - NCT06698666RecruitingPhase 3
Can statins help treat depression?
This trial tests if adding a statin (a cholesterol-lowering medicine) to your current depression treatment improves symptoms. It is for adults aged 20 to 45 with mild to moderate depression who are not already taking a statin.
Cairo, Al AbbasiaAges 20–45 - NCT06844058Recruiting
Religious vs. standard hypnosis for anxiety and depression
This study compares two types of hypnosis (one that includes Islamic themes and one that follows a standard approach) to see which works better for anxiety and depression. It is designed for Muslim adults who are feeling stressed but do not have a formal mental health diagnosis.
IstanbulAges 18–65 - NCT06860958RecruitingPhase 3
Adding roflumilast to antidepressants for depression
This study tests if adding roflumilast, a medicine that reduces inflammation, can help people with major depression feel better when taken with their current antidepressant. It is for adults with moderate to severe depression.
TantaAges 18–65 - NCT06976697Recruiting
Home-based tDCS for major depression
This trial tests a home-use device that sends a small electrical current to the brain to treat major depression. It may be a good option if you are already on antidepressant medication and have a smartphone.
Boston, MassachusettsAges 22–70 - NCT07104916RecruitingPhase 2
Mindfulness and psilocybin therapy for PTSD
This study tests whether a combination of mindfulness training and a single dose of psilocybin can help reduce PTSD symptoms. It is for people with moderate-to-severe PTSD who are not on certain medications and do not have major health problems.
Columbus, OhioAges 21–65 - NCT07115329RecruitingPhase 2
Testing Zelquistinel for major depression
This study tests a new oral medication called Zelquistinel (taken as a tablet) against a placebo for treating major depressive disorder. Researchers want to see if it can reduce depression symptoms, especially when other antidepressants haven't been tried or haven't worked.
Phoenix, ArizonaAges 18–64 - NCT07139834RecruitingPhase 1
Memory and mood study for depression
This study tests how a medication called memantine affects memory and mood in people with major depression who are not currently taking antidepressants. It involves MRI scans and may help find new ways to treat depression.
New York, New YorkAges 18–50 - NCT07204314RecruitingPhase 3
Study of vortioxetine for teens with depression in Japan
This trial tests whether vortioxetine helps reduce symptoms of major depression in Japanese teenagers aged 12-17. It compares the study drug to a placebo to see if it is safe and effective.

Study of an investigational drug for depression
This trial tests an investigational medication for adults with major depressive disorder who are currently taking an antidepressant but still have symptoms. It aims to see if adding this new drug can improve mood better than a placebo.
Garden Grove, CaliforniaAges 18–70 - NCT07523048RecruitingPhase 2
Dextromethorphan-Bupropion for Moderate-to-Severe Depression
This study tests a combination medication (dextromethorphan plus bupropion) to see how it affects brain activity in people with moderate-to-severe depression. Researchers use brain imaging (fMRI) to understand how the drug works and whether it may help relieve depression symptoms.
