Summary

This study is looking at 200 people with treatment-resistant schizophrenia who are starting clozapine. Researchers will measure immune markers in blood and spinal fluid, brain scans, and other tests before and after 12 weeks of treatment. The goal is to find biological signs that predict who will respond well to clozapine, which could help tailor treatment in the future.
