FK949E Elderly ParticipantsFK949EAfter 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.
Primary Outcome Measures
NameTimeMethod
Change From Baseline to Last Assessment in Treatment Period in Montgomery-Asberg Depression Rating Scale (MADRS) Total ScoreBaseline and week 52 (or the time of last assessment for participants who discontinued earlier)

The MADRS is a 10-item scale to measure the severity of depressive episodes, where each item is rated on a scale from 0 to 6. The MADRS total score ranges from 0 to 60 with lower scores indicating less depressive symptoms.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline to Last Assessment in Treatment Period in Hamilton Depression Scale (HAM-D17)Baseline and week 52 (or the time of last assessment for participants who discontinued earlier)

The HAM-D17 is a clinician-rated 17-item scale for assessing the severity of depression symptoms. The scores for each item range from 0 to 4 or 0 to 2, where 0 represents no symptoms. The rating is based on the past 7 days prior to the time of assessment. The total score ranges from 0 to 52 with lower scores indicating less depressive symptoms.

Change From Baseline to Last Assessment in Treatment Period in CGI-BP-S: DepressionBaseline and week 52 (or the time of last assessment for participants who discontinued earlier)

The CGI-BP-S is a scale which assesses a participant's severity of their overall bipolar illness, depression, and mania as assessed by the clinician using a scale from with the scale from 1 (Normal, not ill) to 7 (very severely ill).

Change From Baseline to Last Assessment in Treatment Period in CGI-BP-S: ManiaBaseline and and week 52 (or the time of last assessment for participants who discontinued earlier)

The CGI-BP-S is a scale which assesses a participant's severity of their overall bipolar illness, depression, and mania as assessed by the clinician using a scale from with the scale from 1 (Normal, not ill) to 7 (very severely ill).

Change From Baseline to Last Assessment in Treatment Period in Clinical Global Impression-Bipolar-Severity of Illness (CGI-BP-S): Overall Bipolar IllnessBaseline and week 52 (or the time of last assessment for participants who discontinued earlier)

The CGI-BP-S is a scale which assesses a participant's severity of their overall bipolar illness, depression, and mania as assessed by the clinician using a scale from with the scale from 1 (Normal, not ill) to 7 (very severely ill).

Clinical Global Impression-Bipolar-Change (CGI-BP-C): Overall Bipolar IllnessWeek 52 (or the time of last assessment for participants who discontinued earlier)

The CGI-BP-C is a scale which assesses the degree of change or improvement from baseline for each of overall bipolar illness, depression and mania, by grading it using 8 grades, from 1 (very much improved) to 7 (very much worse) or 8 (not applicable). Grade 8 (not applicable) was regarded as a missing value for purposes of calculating the mean score.

CGI-BP-C: DepressionWeek 52 (or the time of last assessment for participants who discontinued earlier)

The CGI-BP-C is a scale which assesses the degree of change or improvement from baseline for each of overall bipolar illness, depression and mania, by grading it using 8 grades, from 1 (very much improved) to 7 (very much worse) or 8 (not applicable). Grade 8 (not applicable) was regarded as a missing value for purposes of calculating the mean score.

Grade 8 (not applicable) was regarded as a missing value for purposes of calculating the mean score.

Number of Participants With Adverse EventsFrom first dose of study drug up to week 52 (52 weeks)

An adverse event (AE) is defined as any undesirable or unintended sign (including abnormal laboratory test values), symptom, or disease occurring while the study drug was administered, regardless of whether or not there was a causal relationship with the study drug. 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.
