Design outcomes

Primary

MeasureTime frame
Main Objective: Evaluate the effectiveness of clozapine, in association with other antipsychotics, in reducing psychotic symptomatology in treatment-resistant schizophrenia and schizoafective disorder.;Secondary Objective: 1-Study the tolerability of clozapine in treatment-resistant schizophrenia and schizoafective disorder., identifying differences and similarities. 2-Determine the existence of clinical and/or sociodemographic characteristics that help predict the response to clozapine;Primary end point(s): Assess changes (relationship to reducing psychotic symptomatology), and magnitude, in the PANSS scale score in patients with Treatment-resistant schizophrenia and schizoafective disorder. A 25% reduction in the PANSS will be considered to be significant improvement.;Timepoint(s) of evaluation of this end point: The follow-up time to evaluate the changes will be 3 months.

Secondary

MeasureTime frame
Secondary end point(s): 1-To assess tolerability, the UKU scale score will be assessed. 2-Compare the response to Clozapine in the different groups and study correlations of it with the variables included in the sociodemographic, clinical and therapeutic profile.;Timepoint(s) of evaluation of this end point: The follow-up time to evaluate the changes will be 3 months.
