Sequential Multiple-Assignment Randomized Trials to Compare Antipsychotic Treatments(SMART-CAT)

This study is a sequential multiple-assignment randomized trial (RCT) of antipsychotic medication treatment in first-episode schizophrenia patients in the real-world settings.Through analysis of treatment efficacy rate and adverse reactions and pharmacoeconomic evaluation, this project intends to provide evidence for the selection of antipsychotics in FES patients as well as the efficacy and safety of using clozapine in the early phase of schizophrenia treatment by comparing with other SGAs.
