Brief summary

In period I, the treatment effect of FK949E was compared with that of placebo in a blind manner in bipolar disorder patients with major depressive episodes. In period II, the long-term safety and efficacy of FK949E was evaluated.

Detailed description

This study consisted of two parts. In Treatment Period I, FK949E or placebo was administered orally in a blind manner to bipolar disorder patients with major depressive episodes, with the aim of evaluating the superiority of FK949E over placebo and the dose response of two doses of FK949E based on changes in Montgomery-Asberg Depression Rating Scale (MADRS) total score. In Treatment Period II, the long-term safety, efficacy and pharmacokinetics of open-label FK949E was evaluated in patients who completed Treatment Period I. An analysis was performed for data in Treatment Period I and another analysis was done for data in combined Treatment Periods I and II.

CGI-BP-C: Depression (Combined Treatment Period I and II)

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. Baseline for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-10.

CGI-BP-C: Overall Bipolar Illness (Combined Treatment Period I and II)

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. Baseline for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-10.

Time frame: Weeks 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 28, 32, 36, 40, 44, 48, 52 (Placebo/FK949E only from week 12, FK949E 150 mg/FK949E & FK949E 300 mg/FK949E from week 1)

Population: FAS (for combined Treatment Period I and II) participants with available data at each time point; LOCF imputation was used at end of combined treatment period.

Change From Baseline in DIEPSS: Parkinsonism (Combined Treatment Period I and II)

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. Parkinsonism is a total of the gait disturbance, bradykinesia, salivation, muscle rigidity, and tremor scores and ranges from 0 (none, normal) to 20 (severe). Baseline for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-12.

Change From Baseline in MADRS Total Score (Combined Treatment Period I and II)

The MADRS is a10-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 for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-12.

Time frame: Baseline (Week 0 for FK949E 150 mg/FK949E & FK949E 300 mg/FK949E and Week 12 for Placebo/FK949E) and Weeks 1, 2, 3, 4, 6, 8, 10, 12 13, 14, 16, 18, 20, 24, 28, 32, 36, 40, 44, 48, 52

Population: FAS for combined Treatment Period I and II, which included participants who received at least one dose of FK949E and had measurements taken for at least one efficacy endpoint after the start of FK949E treatment, and with available data at each time point. LOCF imputation method was used at end of combined treatment period.

Number of Participants With Adverse Events (Combined Treatment Period I and II)

An 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. AEs reported are AEs that occurred after the start of the FK949E treatment for all groups.

Time frame: Up to 54 weeks (Placebo / FK949E, from week 12 to week 52, for FK949E 150 mg / FK949E & FK949E 300 mg / FK949E groups, from week 0 to week 52)

Number of Participants With an Affirmative Response to Columbia Suicide Severity Rating Scale (C-SSRS): Suicidal Ideation (Treatment Period I)

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.

Time frame: Weeks 4, 8

Number of Participants With an Affirmative Response to C-SSRS: Suicidal Behaviors - Suicide Attempt (Combined Treatment Period I and II)

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 7 items to suicidal behaviors (1. suicide attempt; 2. Self-injury without suicide intent; 3. discontinued suicide attempt; 4. interrupted suicide attempt; 5. preliminary action to suicide; 6. suicidal behavior; 7. completed suicide). Baseline for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-10.

Time frame: Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52 (Placebo/FK949E only from week 12, FK949E 150 mg/FK949E & FK949E 300 mg/FK949E from week 4)

Population: SAF (for combined Treatment Period I and II) participants with available data at each time point; LOCF imputation was used for value at end of combined treatment period.

Number of Participants With an Affirmative Response to C-SSRS: Suicidal Ideation - Suicidal Thoughts (Combined Treatment Period I and II)

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. Baseline for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-10.

Time frame: Weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52 (Placebo/FK949E only from week 12, FK949E 150 mg/FK949E & FK949E 300 mg/FK949E from week 4)

Population: SAF (for combined Treatment Period I and II) participants with available data at each time point; LOCF imputation was used for value at end of combined treatment period.

Number of Participants With HAM-D17 Response (Combined Treatment Period I and II)

A HAM-D17 response was defined as a decrease in HAM-D17 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. Baseline for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-12.

Time frame: Baseline (Week 0 for FK949E 150 mg/FK949E & FK949E 300 mg/FK949E and Week 12 for Placebo/FK949E) and Weeks 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 20, 28, 36, 44, 52

Number of Participants With HAM-D17 Response (Treatment Period I)

A HAM-D17 response was defined as a decrease in HAM-D17 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.

Time frame: Baseline and Weeks 1, 2, 3, 4, 6, 8

Population: FAS; LOCF imputation method was used for all time points.

Number of Participants With MADRS Remission (Combined Treatment Period I and II)

MADRS remission was defined as MADRS total score of 12 or less. 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 for Placebo / FK949E was at week 12 therefore no data were calculated for weeks 1-10.

Time frame: Weeks 1, 2, 3, 4, 6, 8, 10, 12, 13, 14, 16, 18, 20, 24, 28, 32, 36, 40, 44, 48, 52

Population: FAS (for combined Treatment Period I and II) participants with available data at each time point; LOCF imputation method was used at end of combined treatment period.
