The study will be conducted as a randomized, double-blind, placebo-controlled, multi-center study in patients diagnosed with schizophrenia and an acute exacerbation of psychosis. The efficacy and safety of two dose levels of ITI-007 administered daily for 28 days will be evaluated as compared to placebo; risperidone has been included as a positive control.
Upon completion of the inpatient 28-day Study Treatment Period, patients will be started on standard antipsychotic medication and will be stabilized over a 5-day period before discharge from the study clinic. Patients will be seen for a final outpatient safety evaluation at the End-of-Study visit approximately 2 weeks after discharge.
