Overview
Brief Summary
This is a phase 3, flexible-dose, open-label, multi-center study. The subjects who complete the week 8 visit in the prior double-blind study (B2411263) will be eligible to participate in this study. This study consists of 10 month treatment phase and 1-3 week tapering phase. The 2 follow-up visits will be evaluated after 2 weeks and 4 weeks of last study medication dosing.

Outcomes
Primary Outcomes
Number of Participants With Clinical Significant Laboratory Tests Changes
Time Frame: Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months
Clinical significant changes were pre-defined for each laboratory test based on the criteria: Red Blood Cell Count \<0.8 x lower limit normal (LLN); Lymphocytes (%) \<0.8 x LLN; Eosinophils (%) \>1.2 x upper limit normal (ULN); Total Bilirubin \>1.5 x ULN; Alanine Aminotransferase (ALT) \>3.0 x ULN; Gamma glutamyl transferase (GGT) \>3.0 x ULN; Uric Acid \>1.2 x ULN; Cholesterol \>1.3 x ULN; Low density lipoprotein (LDL) cholesterol \>1.2 x ULN; Triglycerides \>1.3 x ULN; Glucose \>1.5 x ULN; Urine Glucose \[qualitative (Qual)\] \>=1; Urine Protein (Qual) \>=1; Urine Blood/Hemoglobin (Hgb) (Qual) \>=1.
Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months
Any untoward medical occurrence in a participant who received study drug was considered an adverse event (AE), without regard to possibility of causal relationship. Treatment-emergent adverse events: those which occurred or worsened after baseline. An AE resulting in any of the following outcomes, was considered to be a serious adverse event: death; lifethreatening; initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect.
Number of Participants With no at Baseline and Yes at Any Post Baseline for Columbia Suicide-Severity Rating Scale (C-SSRS) According to the Columbia Classification Algorithm of Suicide Assessment (C-CASA) Categories
Time Frame: Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months
C-SSRS is a participant rated questionnaire to assess suicidal ideation, suicidal behavior, actual attempts (yes or no responses), and intensity of ideation (rated 1=low severity to 5=high severity). Yes/No responses are mapped to Columbia Classification Algorithm of Suicide Assessment (C-CASA) categories: Completed suicide, suicide attempt, preparatory acts toward imminent suicidal behavior, suicidal ideation, and self-injurious behavior, or no suicidal intent. A participant could have a yes or no response in more than one category.
Number of Participants With Clinical Significant Vital Changes
Time Frame: Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months
Clinical significant changes were pre-defined for systolic blood pressure (SBP), diastolic blood pressure (DBP) , and pulse rate (PR). An average value of 3 measurements in each visit meeting the following criteria for 3 consecutive visits was determined as clinical siginificant changes: DBP \>= 90 mmHg with change from the baseline \>= 10 mmHg; SBP \>= 140 mmHg with change from the baseline \>= 20 mmHg; PR \>= 100 bpm with change from the baseline \>= 15 bpm.
Number of Participants With Clinical Significant Electrocardiogram (ECG) Changes
Time Frame: Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]) up to 10 months
Clinically significant ECG findings included: corrected QT (QTc), QT interval corrected using the Bazett's formula (QTcB), and QT interval corrected using the Fridericia formula (QTcF)\> 450 millisecond (ms), \>480 ms, and \>500 ms respsctively, change from baseline in QTc, QTcB, and QTcF \>= 30 ms, and \>= 60 ms, respectively.
Secondary Outcomes
- Change From Baseline in 16-item Quick Inventory of Depressive Symptomatology Self-Report Japanese Version (QIDS16-SR-J) at Each Post Baseline Time Point(Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]), Weeks 12, 24, 44)
- Change From Baseline in 17-item Hamilton Rating Scale for Depression (HAM-D17) at Each Post Baseline Time Point(Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]), Weeks 1, 2, 3, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44)
- Change From Baseline in Clinical Global Impression - Severity (CGI-S) at Each Post Baseline Time Point(Baseline (Week 8 of the preceding double-blind study B2411263 [NCT01441440]), Weeks 1, 2, 3, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44)
- Mean Clinical Global Impression - Improvement (CGI-I) Score at Each Post Baseline Time Point(Weeks 1, 2, 3, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44)
