Randomized Evaluation of the Effectiveness of Clozapine and Aripiprazole Versus Clozapine and Haloperidol in the Treatment of Schizophrenia

Summary

The principal clinical question to be answered by CHAT (Clozapine Haloperidol Aripiprazole Trial) is the relative efficacy and tolerability of combination treatment with clozapine plus aripiprazole compared to combination treatment with clozapine plus haloperidol in patients with an incomplete response to treatment with clozapine over an appropriate period of time.
