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

Registration Number
NCT03510325
Lead Sponsor
Shanghai Mental Health Center
Brief Summary

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.

Detailed Description

A total of 720 first-episode schizophrenia (FES) patients will be enrolled and followed up for 12 months in this study. The trial includes three treatment phases (each phase lasting for 8 weeks) and a naturalistic follow-up phase. Phase 1 is a 8-week randomized controlled trial; patients will be randomly assigned to one of the treatments with oral olanzapine, risperidone, amisulpride, aripiprazole or perphenazine. Patients who had an acceptable response to the randomly assigned drug therapy will remain on that treatment for a 12-month treatment period. Subjects who fail to respond in phase 1 will switch to phase 2, an equipoise-stratified randomization trial, in which patients will be randomly assigned to oral olanzapine, amisulpride or clozapine for another 8 weeks. No-responders in phase 2 will further enter an open label trial (phase 3). Patients who receive clozapine in phase 2 will be assigned to an extended clozapine treatment or modified electroconvulsive therapy add-on therapy (Phase 3A). Patients who were not assigned to clozapine in phase 2 will be assigned to treatment with clozapine or another SGAs not previously used in phase 1 and 2 (Phase 3B).
