You may qualify if…

• DSM-IV-TR primary diagnosis of Bipolar I Disorder as confirmed by the SCID
• Outpatient receiving treatment with a combination of Depakote plus olanzapine for their bipolar illness and considered clinically stable (e.g., no more than minimal symptoms, no psychiatric hospitalizations, no increase in intensity of clinical interventions) for the preceding 4 months
• Identified at Screening a most bothersome side effect listed in the UKU which makes switching to monotherapy desirable
• MRS total score < 12 on two consecutive ratings, separated by at least 5 days (Screening and Day 1)
• DSS score < 13 on two consecutive ratings, separated by at least five days (Screening and Day 1)
• CGI-S score < 3 on two consecutive ratings, separated by at least five days (Screening and Day 1)
• Serum valproate level > 45 mcg/mL, and a maximum allowable dose of Depakote of 3000 mg/day at Screening
• Olanzapine dose between 5 and 20 mg/day at Screening

You may not qualify if…

• History of schizophrenia or schizoaffective disorder

• Has taken antipsychotics, mood stabilizers, or anticonvulsants (unless specifically for seizure control) other than Depakote or olanzapine in the four months prior to randomization. Other psychotropics (e.g., antidepressants, anxiolytics) with the exception of stimulants, that have been used routinely to maintain stability in the preceding four months may be continued, but not increased or decreased
