This study looks at “biomarkers,” or blood measures, in people with schizophrenia who respond to clozapine. It may help researchers understand who benefits from clozapine and why, by linking test results to symptom changes.
Glostrup Municipality, DenmarkAges 18–64 - NCT05349513Recruiting
Testing a home-care program for schizophrenia-like disorders
This study tests a specific kind of care delivered in a home-like setting for people with schizophrenia or schizoaffective disorder. It may help the care team understand what kinds of supports work best and improve day-to-day treatment.
PoitiersAges 18–65 - NCT05343598Recruiting
Using TMS to study hallucinations in schizophrenia
This study uses a non-invasive brain stimulation method (TMS) along with brain scans (MRI) to better understand why hallucinations happen in schizophrenia. It may help researchers learn more about brain processes involved, which could guide future treatments.
Belmont, MassachusettsAges 18–55 - NCT05296720Recruiting
EEG study of touch prediction in people with schizophrenia
This study uses a special brain test (EEG) while you do a touch-related task to see how your brain predicts what comes next. It may help researchers understand brain and behavior differences in schizophrenia and how sensory processing works.
StrasbourgAges 18–60 - NCT05276050Recruiting
Brain-circuit treatment to help people with schizophrenia quit smoking
This study tests a circuitry-guided approach to help people with schizophrenia quit smoking. It may help reduce cravings and improve quitting, while also watching for safety issues.
Houston, TexasAges 22–65 - NCT05303064RecruitingPhase 3
Study of weight gain medicine for teens with certain mood or psychosis
This Phase 3 study tests a treatment aimed at reducing unhealthy weight gain in teens with schizophrenia or bipolar I disorder, using changes in BMI (a height-and-weight measure). It may help families who are concerned about weight changes that can happen with some psychiatric medicines.
Dothan, AlabamaAges 10–17 - NCT05208190RecruitingPhase 4
Clozapine to prevent violence in schizophrenia
This trial tests whether clozapine can reduce repeat violent behavior in people with schizophrenia or schizoaffective disorder. Participants are randomly assigned to clozapine or usual care to see which approach works better for preventing violence.
Los Angeles, CaliforniaAges 18–65 - NCT05240976RecruitingPhase 2
Testing add-on treatments for very treatment-resistant schizophrenia
This trial tests a combination of an NMDA-targeting medicine and an anti-inflammatory treatment for people with schizophrenia that has not responded well to several standard treatments, including clozapine. If you qualify, the goal is to see whether this combination improves symptoms more than usual care.
TaichungAges 18–65 - NCT05159349Recruiting
Studying mental health support for adults with schizophrenia
This trial is studying mental health across the daily life of people living in the community who have schizophrenia. It may help by improving how care is planned and supported over time for people living in Shanghai.
ShanghaiAges 18–65 - NCT05165316Enrolling by invitation
Long-acting antipsychotic options for schizophrenia
This study looks at long-acting (extended-release) antipsychotic medicine options in people with schizophrenia, compared with regular tablets. You may be able to join if you were already part of a related earlier study or its real-world follow-up.
Ramat GanAges 18 years+ - NCT05102929Recruiting
Brain-training for working memory in early schizophrenia
This study looks at whether a treatment that targets brain “rhythms” can improve working memory in people who are in the early stage of schizophrenia. It may help the brain process information more effectively, which can support daily thinking and functioning.
Pittsburgh, PennsylvaniaAges 18–40 - NCT05025605RecruitingPhase 1
Study medicine for agitation in youth with bipolar or schizophrenia
This Phase 1 trial tests whether BXCL501 is safe and can help reduce agitation in children and teens who have bipolar disorder or schizophrenia. You may be considered if your agitation is significant during screening, but certain recent medication and health factors can make you ineligible.
Anaheim, CaliforniaAges 10–17 - NCT05052853RecruitingPhase 2
Early treatment trial for early schizophrenia warning signs
This Phase 2 study tests an NMDA-enhancer medicine to see if it can help people who are in the early “prodromal” stage—when symptoms are starting but full schizophrenia is not diagnosed yet. It aims to reduce or prevent worsening symptoms over the study period.
TaichungAges 13–45 - NCT04887792RecruitingPhase 1/Phase 2
Acetazolamide for schizophrenia that hasn’t improved
This Phase 1/2 study tests whether acetazolamide can help people with treatment-resistant schizophrenia. It aims to see if adding this medication improves symptoms when standard antipsychotics haven’t worked enough.
Pittsburgh, PennsylvaniaAges 18–55 - NCT04871048Recruiting
tDCS training to reduce cannabis use in people with schizophrenia
This trial tests whether a non-painful brain stimulation method (tDCS) can help people with schizophrenia who also have moderate-to-severe cannabis use disorder reduce or quit cannabis. It also involves MRI scanning to help study brain changes.
BronAges 18–60 - NCT04745143RecruitingPhase 2
NMDA-enhancer medicine tested for schizophrenia without antipsychotics
This Phase 2 trial tests a single medicine intended to help people with schizophrenia who cannot take standard antipsychotic medications due to side effects or poor response. It may help reduce schizophrenia symptoms, but whether you can join depends on your diagnosis, medication history, and health conditions.
TaichungAges 18–65 - NCT04432116Recruiting
Virtual reality training for schizophrenia and bipolar symptoms
This study looks at whether virtual reality and time-based training can improve symptoms for people with schizophrenia or bipolar disorder. You may do virtual-reality tasks as part of your care plan while the team tracks changes over time.
StrasbourgAges 18–60 - NCT04267003Recruiting
Brain stimulation study for thinking and brain chemistry in schizophrenia
This study tests whether a brain stimulation approach can improve thinking (cognition) in people with schizophrenia and how it changes brain electrical signals and a brain chemical called GABA. It may help researchers understand new ways to support thinking and symptoms.
Sacramento, CaliforniaAges 18–47 - NCT04159662Recruiting
Brain scans to study thinking in schizophrenia and depression
This study uses brain imaging to better understand how thinking works in people with schizophrenia or major depression. Your results may help researchers learn what brain patterns match different thinking and symptoms.
Ottawa, OntarioAges 18–60 - NCT04226898RecruitingPhase 2
Synbiotic supplement to lessen schizophrenia symptoms
This Phase 2 trial tests whether a “synbiotic” supplement (a mix of probiotics and prebiotics) can reduce symptoms of schizophrenia or schizoaffective disorder. It may help by targeting gut-related immune and inflammation pathways that could affect brain symptoms.
Batlimore, MarylandAges 18–65 - NCT04113993RecruitingPhase 4
Bazedoxifene study in women with schizophrenia
This trial tests whether bazedoxifene can help women with schizophrenia who are stable on their current medicines. You may be asked to do questionnaires and thinking (cognitive) tests to see if symptoms or brain-related measures change.
