Recruiting studies in Massachusetts
- NCT06830044RecruitingPhase 3
Adding an experimental drug for major depression
This trial tests if adding a new medicine called milsaperidone can help people with major depression who haven't gotten enough relief from their current antidepressant. It aims to see if the combination works better than the antidepressant alone.
Boston, MassachusettsAges 18–65 - NCT06816329Recruiting

Study of an experimental psychedelic-like drug for depression (CYB003)
This study tests an investigational medication (CYB003) for people with major depression whose current antidepressant isn't working well enough. It looks at whether this treatment can help improve depression symptoms.
Boston, MassachusettsAges 18–85 - NCT06792175Enrolling by invitation

Brookline, MassachusettsAges 13–60 - NCT06786624RecruitingPhase 3
Testing a new drug for depression that hasn't fully responded to treatment

Watertown, MassachusettsAges 18 years+ - NCT06633016RecruitingPhase 2
ABX-002 for major depression (add-on treatment)
This trial tests a new medication called ABX-002 as an add-on to your current antidepressant. It's for people with moderate to severe depression who haven't gotten enough help from their current antidepressant alone.
Boston, MassachusettsAges 18–65 - NCT06559306RecruitingPhase 3
Seltorexant for depression with insomnia symptoms
This trial tests if adding seltorexant to your current antidepressant can improve depression and sleep problems. It is for people with major depressive disorder who still have symptoms, especially insomnia, despite trying at least one antidepressant.
Watertown, MassachusettsAges 18–74 - 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.
Russells Mills, MassachusettsAges 18–64 - NCT04296604Recruiting
tDCS brain stimulation to improve thinking and mood
This study tests whether a non-surgical brain stimulation called tDCS can improve “executive function,” which means skills like planning, focus, and decision-making. It is designed for people with several mental health and substance-use conditions, and it may help you if those skills are affected by your diagnosis.
Boston, MassachusettsAges 18–65 - NCT05570812RecruitingPhase 2
Pregnenolone to improve depressed mood in people with HIV
This Phase 2 trial tests a brain-acting steroid called pregnenolone to help reduce depressed mood. It studies whether it can improve mood in adults with HIV who are already on HIV treatment and still have depression symptoms.
Boston, MassachusettsAges 18–85 - NCT06376734RecruitingPhase 2
TMS for depression, anxiety, OCD, or schizophrenia
This study tests whether a brain stimulation technique called TMS can help people with depression, anxiety, OCD, or schizophrenia. It aims to find better ways to target the treatment for each person's specific needs.
Boston, MassachusettsAges 18–65 - 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 - NCT05630963Recruiting
Study sleep-like brain signaling in major depression
This trial looks at how a specific brain receptor related to pain signals (nociceptin/orphanin FQ receptor) may be involved in depression. It may help researchers understand depression better by comparing people with current versus past (remitted) major depression.
Belmont, MassachusettsAges 18–45 - 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.
Methuen, MassachusettsAges 18–65 - NCT05800925Recruiting
Triage survey to check who can join psychiatry research
This study uses a short questionnaire to figure out who is eligible to join future psychiatry research. It may help people get routed into studies that match their situation and safety needs.
Boston, MassachusettsAges 18 years+ - NCT05573074Recruiting
Light treatment trial for brain blood flow in depression
This study tests whether shining near-infrared light through the head can change brain blood flow and reduce depression symptoms. If you have major depression, you may be offered a non-drug, device-based approach to see how well it helps.
Boston, MassachusettsAges 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 - NCT05523817Recruiting
Brain scan targeting to improve specific depression symptoms
This study uses brain-signal targeting (likely with MRI) to see whether it can improve certain symptoms of depression. You may be able to join if you’re 18–65 and currently have a depressive episode, and if you can safely complete the scan.
Boston, MassachusettsAges 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 - NCT04788524Recruiting
Brain and stress study in depressed teens with control feelings
This study uses brain scans and short real-life mood/stress check-ins to understand how stress and perceived control work in teens with depression. It may help researchers better pinpoint brain patterns linked to depression and how teens experience control during stressful moments.
Belmont, MassachusettsAges 14–18 - NCT07484217RecruitingPhase 3
Testing solriamfetol for depression with daytime sleepiness
This study tests if the drug solriamfetol can help people with major depression who also feel very tired during the day. It aims to improve both mood and daytime sleepiness.
Springfield, MassachusettsAges 18–65 - NCT06136546RecruitingPhase 2
Infliximab for depression with cognitive problems
This trial tests if a medicine called infliximab, given through an IV, can help improve thinking and memory problems in people with moderate to severe depression who also have high inflammation levels. It aims to see if lowering inflammation can ease both mood and cognitive symptoms.
Boston, MassachusettsAges 25–50 - NCT06656416RecruitingPhase 2
Study of ALTO-100 for bipolar depression

What taking part in a major depressive disorder study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
