The primary objective of the study is to determine if armodafinil treatment, at a dosage of 150 mg/day, is more effective than placebo treatment as adjunctive therapy for adults who are experiencing a major depressive episode associated with Bipolar I Disorder and who are inadequately responsive to their current treatment for a current major depressive episode.

Patients were randomly assigned to begin oral treatment with armodafinil, which was titrated to 150 mg/day (3 tablets). Armodafinil was titrated up to the target dosage of 150 mg/day (daily dose was administered each morning). Patients began taking blinded armodafinil at a dose of 50 mg/day (1 tablet) on the day following the baseline visit. Doses were increased by 50 mg/day (1 tablet) to a dose of 100 mg/day on Day 2 and 3, and then again by 50 mg /day on day 4 for a target dose of 150 mg/day. Following titration, patients continued taking 150 mg/day of armodafinil for the duration of the study. If a patient was unable to tolerate (recurrent or persistent adverse events) the study drug, 1 reduction in dosage (ie, minimum dosage 100 mg/day \[2 tablets\]) was allowed. The dosage could not be increased after it was decreased.
Patients were randomly assigned to begin oral treatment with placebo, which was titrated to 3 tablets. Placebo tablets matching the 50 mg armodafinil tablet were used in a manner identical to that of the armodafinil tablets. Study drug was titrated up to the target dosage of 3 tablets / day (daily dose was administered each morning). Patients began taking blinded study drug at a dose of 1 tablet daily on the day following the baseline visit. Doses were increased by 1 tablet to a dose of 2 tablets/day on Day 2 and 3, and then again by 1 tablet /day on day 4 for a target dose of 3 tablets/day. Following titration, patients continued taking 3 tablets/day of study drug for the duration of the study. If a patient was unable to tolerate (recurrent or persistent adverse events) the study drug, 1 reduction in dosage (ie, minimum dosage 2 tablets/day) was allowed. The dosage could not be increased after it was decreased.

Change From Baseline to Endpoint (Week 8 or Last Observation After Baseline) in the Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
The MADRS is a 10-item scale to evaluate the overall severity of a patient's depressive symptoms, that is completed by the physician. The rating scale makes use of both observational clues as to the subject's level of depression (eg. apparent sadness) and verbal indicators of depression expressed by the patient. Each of the 10 items is graded on a 6-point scale with anchors at 2 point intervals. Total scores range from 0 to 60, with the higher number indicating more severe symptoms of depression. Here we present data summarizing the change in MADRS from Baseline to Endpoint.
