Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to Last Assessment in Treatment Period in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
Time Frame: Baseline 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.
Baseline and week 52 (or the time of last assessment for participants who discontinued earlier)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to Last Assessment in Treatment Period in Hamilton Depression Scale (HAM-D17)
Time Frame: 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.
Baseline and week 52 (or the time of last assessment for participants who discontinued earlier)
Change From Baseline to Last Assessment in Treatment Period in Clinical Global Impression-Bipolar-Severity of Illness (CGI-BP-S): Overall Bipolar Illness
Time Frame: Baseline 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).
Baseline and week 52 (or the time of last assessment for participants who discontinued earlier)
Change From Baseline to Last Assessment in Treatment Period in CGI-BP-S: Depression
Time Frame: Baseline and week 52 (or the time of last assessment for participants who discontinued earlier)

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

Time Frame: Week 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.
Week 52 (or the time of last assessment for participants who discontinued earlier)
CGI-BP-C: Mania
Time Frame: Week 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.
Week 52 (or the time of last assessment for participants who discontinued earlier)
Number of Participants With Adverse Events
Time Frame: From 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.
