What this research studies

If you join, you would be randomly assigned to take clozapine or to continue your usual antipsychotic care for 24 weeks. The trial is open-label (you and your doctors know the treatment) but outcomes will be rated by staff who do not know which treatment you received, and it will run at seven participating sites. The team plans to enroll about 280 people with schizophrenia who are judged to be at high risk for violence and will track time to any violent act as the main outcome. Participation will involve regular clinic visits and the blood monitoring required for safe clozapine use.

Who could benefit from this research

Good fit: Adults with a diagnosis of schizophrenia who are considered at high risk for violent behavior, are treated in outpatient/community settings, and are willing to take clozapine with required blood monitoring.

Not a fit: People without schizophrenia, those at low risk for violence, or anyone who cannot take clozapine or refuses the necessary blood tests are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, this could lower violent behavior, improve safety and clinical outcomes, and help guide use of clozapine in community care.

How similar studies have performed: Several observational and small trials have suggested clozapine can reduce aggression, but large randomized outpatient trials confirming effects on violent acts are lacking.
