  4. On a stable regimen of treatment to include quetiapine fumarate for 3 months minimum prior to screening, and on a dose of quetiapine fumarate totaling 600 mg total per day for a minimum of 1 month prior to screening. Patients who are on qd dosing of daily quetiapine fumarate must be willing to convert to 300 mg bid dosing for the duration of the study.

Exclusion Criteria:

  1. All other DSM-IV axis I diagnoses, including schizoaffective disorder, schizophreniform disorder and/or any other psychiatric diagnoses that in the opinion of the principal investigator may during the conduct of the trial become a primary treatment concern, or may interfere in the patients ability to participate in the trial.
