Summary

This study will determine the effectiveness of clozapine versus olanzapine in treating people with schizophrenia that has not improved with treatment.

Detailed description

This is a two-year open-label, randomized trial of the comparative effectiveness of clozapine versus olanzapine in patients with treatment refractory schizophrenia. The objective is to determine whether in a naturalistic setting olanzapine is a logical treatment choice (before using the more toxic clozapine) for some treatment refractory patients.
