Clozapine to reduce violence in people with schizophrenia
4/7 Clozapine for the Prevention of Violence in Schizophrenia: a Randomized Clinical Trial
This trial will compare clozapine with usual antipsychotic care to see whether clozapine lowers the chance of violent acts in people with schizophrenia who are at high risk.

What this research studies
If you join, you'll be randomly assigned to receive clozapine or your usual antipsychotic treatment for 24 weeks. The trial is open-label so your treating clinicians will know your medication, but the people who rate outcomes will be blinded. About 280 adults with schizophrenia judged to be at high risk for violence will be enrolled across seven community sites coordinated by the New York State Psychiatric Institute and led by the University of Maryland Baltimore. The study will track violent acts and safety measures, including regular blood tests required for clozapine.
Who could benefit from this research
Good fit: Adults diagnosed with schizophrenia who are considered at high risk for violent behavior and who can comply with clozapine's required blood monitoring are the best fit.
Not a fit: People without schizophrenia, those not judged to be at elevated risk for violence, or anyone with medical contraindications to clozapine (for example low white blood cell counts, inability to comply with blood monitoring, or pregnancy) are unlikely to benefit.
Why it matters
Potential benefit: If successful, this could lower violent behavior and improve safety, clinical outcomes, and stigma for people with schizophrenia.
How similar studies have performed: Smaller and mostly observational studies have suggested clozapine reduces aggression, but large randomized effectiveness trials in community outpatient settings have not previously answered this question.
