• Non pregnant female patients who agree to use acceptable birth control
• At entry to the study must be considered moderately ill in the opinion of the investigator
• Willing to participate in a minimum of 3 weeks of inpatient hospitalization and this must be appropriate for the patient in the clinical judgment of the investigator.
• 1 year history of Schizophrenia prior to entering the study
• At study entry patients with a history of antipsychotic treatment must have a lifetime history of at least one hospitalization for the treatment of schizophrenia, not including the hospitalization required for study. Patients who have never taken antipsychotic treatment may enter the study even without a history of hospitalization.
• At study entry patients with a history of antipsychotic treatment must have a history of at least one episode of illness exacerbation requiring an intensification of treatment intervention or care in the last 2 years, not including the present episode of illness.

• At study entry patients must have experienced an exacerbation of illness within the 2 weeks prior to entering the study, leading to an intensification of psychiatric care in the opinion of the investigator. If exacerbation occurs in patients who are presently hospitalized, the patient must not have been hospitalized longer than 60 days at entry of the study

  • head trauma, stroke, or CNS infection with persistent neurological deficit (focal or diffuse);
  • brain surgery;
  • an electroencephalogram with paroxysmal (epileptiform) activity, or
  • brain structural lesion, including developmental abnormalities, as determined by examination or previous neuroimaging studies that are consistent with a diagnosable neurological disease or syndrome.
• Electroconvulsive therapy (ECT) within 3 months of entering the study or who will have ECT at any time during the study.
• Leukopenia
• Medical history of Human Immunodeficiency Virus positive (HIV+) status.
