A Study to Evaluate the Efficacy of FK949E in Bipolar Disorder Patients With Major Depressive Episodes

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.

The MADRS total score ranges from 0 to 60 with lower scores indicating less depressive symptoms. Baseline for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-12.

A MADRS response was defined as a decrease in MADRS total score of 50% or more from baseline.

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, where a higher score indicates a greater depressive state.

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.

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, required or prolonged hospitalization or was considered medically important.

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, required or prolonged hospitalization or was considered medically important. AEs reported are AEs that occurred after the start of the FK949E treatment for all groups.

The DIEPSS is a scale used to evaluate drug-induced extrapyramidal symptoms. DIEPSS is composed of 8 individual symptom parameters and a global assessment of severity, each rated on a 5-point scale, with lower scores indicating as "normal." The DIEPSS total score ranges from 0 (none, normal) to 32 (severe), and excludes the global assessment of severity.

The YMRS is a scale used to evaluate manic symptoms. The YMRS total score was the total assessment of assessed points for 11 items, ranges from 0 to 60 (each item is scored from either 0-4 or 0-8 by severity (0 = absent and 4/8 = displays mood/behavior to a greater degree). A lower score indicates "Absent" or "Normal."

The C-SSRS is a scale for assessing risk for suicidal behavior and suicide ideation and was administered by the clinician. Affirmative or negative responses were provided to 5 items for suicide ideation (1. Wish to be dead; 2. Suicidal thoughts; 3. Suicidal thoughts with a method (no specific plan or intent to act); 4. Suicidal intent (without a specific plan); 5. Suicidal intent with specific plan. If participants responded with a negative response for questions 1 and 2, the remaining questions are skipped. If question 2 was responded to with a positive response, the remaining questions need to be asked.
