- Brief summaryIn the European First Episode Schizophrenia Trial (EUFEST) we study the effectiveness of antipsychotic drugs in patients with recent onset schizophrenia. EUFEST assesses the effectiveness of a low dose of haloperidol versus regular doses of 4 second generation antipsychotics: amisulpride, olanzapine, quetiapine, and ziprasidone on loss of retention. We focus on the real world treatment of first episode patients by enrolling heterogeneous patient populations, including patients who show comorbid drug abuse or who are aggressive or suicidal or less likely to be compliant with treatment. The principal investigators are Prof.dr. René S Kahn and Prof.dr. W Wolfgang Fleischhacker.
