A serious AE is defined as a an event resulting in death, persistent or significant disability/incapacity or congenital anomaly or birth defect, was life-threatening, re quire d or prolonged hospitalization or was considered medically important.

Participant flow

Recruitment details

Elderly participants with documented clinical diagnosis meeting the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, Text Revision criteria for bipolar I disorder or bipolar II disorder, with most recent episode depressed confirmed by the Mini-International Neuropsychiatric Interview were recruited from 32 sites in Japan.

Pre-assignment details

Participants who were not taking quetiapine or was at \< 50 mg/day at least 28 days prior to informed consent, FK949E was administered at an initial dose of 50 mg during the dose-titration period. Participants who were taking quetiapine at 50 to \< 300 mg/day or 300 mg/day, FK949E was administered at 150 mg/day during the dose-titration period.

FK949E Elderly Participants
After 2 days of dose-titration, elderly participants received either FK949E 150 mg or FK949E 300 mg once daily at bedtime from day 3 to week 52. Dose increase and reduction was allowed following dose increase or reduction guidelines and at the investigator's discretion. After which, participants went through a follow-up period of 1 week. For participants, who completed or discontinued treatment at FK949E 300 mg, a dose-tapering period was placed before proceeding to the follow-up period, and FK949E 150 mg was administered once daily for 1 week in this period.
