Recruiting studies
- NCT03973268RecruitingPhase 1
Ketamine study to understand treatment response in hard-to-treat depression
This early-stage study tests ketamine and looks at what brain changes may explain why it helps people with major depression that hasn’t improved with usual treatments. You may be asked to stay in the hospital and complete detailed interviews, mood rating scales, and brain imaging.
Bethesda, MarylandAges 18–70 - NCT05418894Recruiting
Study brain signals and improve treatment-resistant depression
This trial studies how brain activity relates to feelings and depression, using brain electrodes to measure signals. It’s meant for people with long-lasting, treatment-resistant major depression who may need stimulation while continuing psychiatric care.
Houston, TexasAges 22–70 - NCT05518578RecruitingPhase 2
Drug trial for hard-to-control focal epilepsy with brain scar
This Phase 2 trial tests SPN-817 in adults whose seizures are still not well controlled despite trying multiple seizure medicines. It targets people with a specific type of brain finding called focal cortical dysplasia and looks at safety/tolerability and seizure outcomes over several weeks.
Jacksonville, FloridaAges 18–70 - NCT05905705Recruiting
ECT plus a sleep monitor for treatment-resistant depression
This study looks at how electroconvulsive therapy (ECT) affects brain activity and sleep patterns in people with difficult-to-treat depression. It uses a wearable sleep monitor (the Dreem device) to record sleep while you receive ECT.
St Louis, MissouriAges 21–65 - NCT06278909Recruiting
Nerve stimulation for stubborn anxiety
This study tests a new, non-invasive treatment using mild electrical stimulation on a nerve in your face (trigeminal nerve) to help with anxiety that hasn't improved with other treatments. It aims to see if this approach is safe and helpful for people with generalized anxiety disorder who have not responded to standard medications.
Kingston, OntarioAges 18–65 - NCT06370988Recruiting
Theta-burst stimulation for bipolar depression
This study tests a type of brain stimulation (theta-burst TMS) to see if it helps improve depression in people with bipolar disorder. It might be a good option if you have tried medication but still feel depressed.
Toronto, OntarioAges 18–65 - NCT06599099Recruiting
Deep brain stimulation for depression that hasn't responded to other treatments
This trial tests if deep brain stimulation (a surgical implant that sends gentle electrical pulses to a specific area of the brain) can help people with bipolar I disorder who are currently in a severe depressive episode and have not found relief from multiple treatments.
Boston, MassachusettsAges 22–64 - NCT07382596RecruitingPhase 4
Cervical injections for treatment-resistant PTSD
This study tests if injecting a sugar-water solution around neck nerves can help PTSD that hasn't improved with standard treatments. Half the participants get sugar-water, half get salt-water, and you'll be assigned to usual care for 3 months first.
Lexington, KentuckyAges 19–90 - NCT02122562RecruitingPhase 2
Ketamine treatment for depression that hasn’t responded to care
This Phase 2 study tests ketamine for people with major depression that hasn’t improved after at least one antidepressant. It aims to see whether ketamine can reduce depression symptoms during a current depressive episode.
Iowa City, IowaAges 18–55 - NCT03320304Recruiting
VNS for long-term depression that hasn’t improved with treatment
This trial studies how well and how efficiently VNS therapy works for people with long-lasting or repeated major depression that hasn’t responded to enough antidepressant treatments. It may help patients who are already receiving depression treatment but are still struggling.
ViennaAges 18 years+ - NCT07603804Recruiting
Accelerated Brain Stimulation for Treatment-Resistant Depression
This study tests an accelerated form of iTBS (a non-invasive brain stimulation technique) for depression that hasn't improved with antidepressant medications. The goal is to help people with major depression who haven't responded adequately to at least one antidepressant drug.
IstanbulAges 18–65 - NCT06611592RecruitingPhase 2
Pramipexole for hard-to-treat OCD
This study tests if pramipexole can help people whose OCD hasn't improved with standard treatments like SSRIs or certain antipsychotics. You might qualify if standard therapies haven't worked for you.
BragaAges 18–64 - NCT07363577RecruitingPhase 3
Testing LB-102 for adults with acute schizophrenia
This trial tests a new medication called LB-102 for people with acute (sudden worsening of) schizophrenia. It aims to see if the drug helps reduce symptoms like hallucinations or disorganized thinking.
Bentonville, ArkansasAges 18–65 - NCT05528926Recruiting
Resist irritability: a trial for children with ongoing behavior issues
This trial tests a program meant to reduce long-lasting irritability in children and teens who have conditions like ADHD, oppositional behavior, disruptive behavior, mood/anxiety problems, or DMDD. It includes children whose parents rate irritability as at least moderately severe and who have had symptoms for 6 months or more.
MontpellierAges 6–15 - NCT07467993RecruitingPhase 2
Testing GXV813 for hospitalized adults with schizophrenia
This trial tests a new drug, GXV813, to see if it helps reduce symptoms in people with schizophrenia who are currently hospitalized due to a sudden worsening of their condition. It compares the drug's safety and effect against a placebo over several weeks.
Bentonville, ArkansasAges 18–65 - NCT06863350Recruiting
Closing a heart hole to treat drug-resistant epilepsy
This trial tests if closing a small hole in the heart (called a PFO) can reduce seizures in people whose epilepsy isn't controlled by medication. It might offer a new treatment option for those who have both drug-resistant epilepsy and this heart condition.
Chengdu, SichuanAges 18–60

Common questions
- Are there clinical trials for treatment resistant schizophrenia?
- Yes. Clin2 currently lists 64 recruiting treatment resistant schizophrenia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a treatment resistant schizophrenia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a treatment resistant schizophrenia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
