Trial Outcomes & Findings for Study to Evaluate the Effects of Switching Different Strength Forms of FK949E in Bipolar Disorder Patients With Major Depressive Episodes (NCT NCT02362412)

Participants with documented clinical diagnosis meeting the DSM-IV-TR criteria for bipolar I disorder or bipolar II disorder, with most recent episode depressed (296.50 to 296.54 or 296.89) confirmed by the Mini-International Neuropsychiatric Interview (M.I.N.I.) were recruited from 10 sites in Japan.

After informed consent was obtained and prior to randomization in Treatment Period II, participants entered Treatment Period I (4 weeks) to allow a dose titration and reduction for adjusting the dosage regimen of FK949E. Two participants did not enter Treatment Period II (due to an adverse event and withdrawal of consent, respectively).

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 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.

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).

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 abnonmal 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.
