This is an Open-label, Multi-center, Extension Study Designed to Evaluate the Longer Term Safety, Tolerability and Effectiveness of Lurasidone, Flexibly Dosed, Adjunctive to Lithium or Divalproex for the Treatment of Subjects With Bipolar I Disorder Who Have Participated in Study D1050296

The QIDS-SR16 is a 16-item self-report measure of depressive symptomatology which uses a computerized assessment interface for administration. The scoring system for the QIDS-SR16 converts responses to 16 separate items into nine DSM-IV symptom criterion domains. The nine domains comprise: depressed mood (Item 5); concentration/decision making (Item 10); self outlook (Item 11); suicidal ideation (Item 12); decreased interest (Item 13); decreased energy (Item 14); sleep disturbance (initial, middle, and late insomnia or hypersomnia) (highest score of Items 1 to 4); appetite/weight disturbance (highest score of Items 6 to 9); and psychomotor disturbance (highest score of Items 15 and 16). The QIDS-SR16 total score is calculated as the sum of the 9 domain scores. The QIDS-SR16 total score ranges from 0 to 27 with a high score indicating more severe symptoms.

The PANSS-P is a subset of items in the PANSS, an interview-based measure of the severity of psychopathology in adults with psychotic disorders. The measure contains seven questions to assess delusions, conceptual disorganization, hallucinations behavior, excitement, grandiosity, suspiciousness/persecution, and hostility. An anchored Likert scale from 1-7, where values of 2 and above indicate the presence of progressively more severe symptoms, is used to score each item. The PANSS-P subscale score is the sum of the 7 items and ranges from 7 through 49. A higher score is associated with greater illness severity.

Movement disorders as assessed by Young Mania Rating Scale (YMRS) The YMRS is an 11-item instrument used to assess the severity of mania in subjects with a diagnosis of bipolar disorder. Ratings are based on patient self-reporting, combined with clinician observation (accorded greater score). The YMRS total score is calculated as the sum of the 11 items. The YMRS total score ranges from 0 to 60. Higher scores are associated with greater severity of mania.

Depression as assessed by Montgomery-Asberg Depression Rating Scale (MADRS) -The MADRS consists of 10 items, each rated on a Likert scale, from 0="Normal" to 6="Most Severe". The MADRS total score is calculated as the sum of the 10 items. The MADRS total score ranges from 0 to 60. Higher scores are associated with greater severity of depression.

Severity of illness as assessed by the Clinical Global Impression Bipolar Version, Severity of Illness (CGI-BP-S) -The CGI-BP-S overall score is a single value, clinician-rated assessment of overall bipolar illness severity and ranges from 1= 'Normal, not at all ill' to 7= 'Among the most extremely ill patients'. A higher score is associated with greater illness severity.

The CGI-BP-S mania score is a single value, clinician-rated assessment of mania illness severity and ranges from 1=Normal, not at all ill to 7= Among the most extremely ill patients. A higher score is associated with greater illness severity

The CGI-BP-S depression score is a single value, clinician-rated assessment of depression illness severity and range from 1=normal, not at all ill to 7=Among the most extremely ill patients. A higher score is associated with greater illness severity.

The SDS is a composite of three self-rated items designed to measure the extent to which three major sectors in the patient's life are impaired by depressive symptoms. The SDS total score is calculated as the sum of the 3 items. The SDS total score ranges from 0 to 30. Higher scores are associated with greater severity of global functional impairments. If a subject has not worked/studied at all during the past week for reasons unrelated to the disorder, the SDS total score will be set to missing.
