  • Patients must meet the following psychopathologic severity criteria at screening: Positive and Negative Syndrome Scale (PANSS) total score, of at least
  • Patients must receive a rating of 4 (moderately ill) or greater on the Clinical Global Impression-Severity (CGI-S) scale at screening.
  • Patients in whom, in the opinion of the investigator, a switch to another antipsychotic medication or initiation of an antipsychotic medication is indicated.

  • Patients who require concomitant treatment with any other medication with primary central nervous system activity, other than certain allowed medications as specified in Study Protocol.
  • Patients receiving treatment with depot antipsychotic medication within 1 dosing interval, minimum of 4 weeks, prior to screening.
