Primary | Number of Manic Episodes According to the Young Mania Rating Scale | Young Mania Rating Scale is an 11-item, clinician-administered scale to assess severity of manic symptoms before, during and after treatment. Four items are graded on a min. 0 to max. 8 scale (irritability, speech, thought content and disruptive/aggressive behavior) while the remaining 7 items are graded on a min. 0 to max. 4 scale. A score of 0 indicates behavior is absent and score of 4 or 8 indicates the behavior is present and severe. The change in score between Baseline and the Completion Visit will be reported. Ideally, the two time points will be Baseline and 6 Weeks after Baseline, but if a subject terminates early, the last Young Mania Rating Scale score will be used. The scores from each question are added for a total score ranging from min. 0 to max 60; higher scores indicate greater severity of symptoms. A score of 0-12 indicates the absence of mania or a very mild manic state, a score of 13-20 or higher indicates a mild manic episode, and over 20 indicates a manic state. |

Secondary | Number of Depressive Episodes Per Patient Visit According to the Hamilton Depression Scale | The Hamilton Depression Rating Scale is a tool used to determine a patient's level of depression before, during, and after treatment. The Hamilton Depression Scale form lists 21 items, but the scoring is based on the first 17 questions. Eight items are scored on a 5-point scale, ranging from 0 (min) = not present to 4 (max) = severe. Nine are scored from 0 (min) to 2 (max). The sum of the scores from the first 17 questions is: 0 (min) to 7 (max) = normal, 8 (min) to 13 (max) = mild depression, 14 (min) to 18 (max) = moderate depression, 19 (min) to 22 (max) = severe depression and = 23=very severe depression. A score of 11 or more indicates a depressive episode in terms of this outcome measure. | 2 years | |
Secondary | Number of Psychiatric Hospitalizations | The number of psychiatric hospitalizations that occur during the study will be compared to the number of hospitalizations that occurred prior to the study. | 2 years |
