Percentage of Participants With Remission as Assessed by the Montgomery-Asberg Depression Rating Scale (MADRS) Score at Week 8 |
Percentage of participants with remission as assessed by the MADRS at Week 8 was reported. The MADRS is a clinician-rated scale designed to measure depression severity and to detect changes due to antidepressant treatment. The scale consists of 10 items, each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition. The MADRS evaluates apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts. A participant was defined as being in remission if the MADRS total score was less than or equal to (<=)10 and no treatment or study discontinuation before Week 8. |

Percentage of Participants With Both Remission at Week 8 and Relapse-free Until Week 32 |
Percentage of participants with both remission at Week 8 and relapse-free until Week 32 were reported. A participant was defined as being in remission if the MADRS total score was <= 10 and no treatment or study discontinuation before Week 8. A relapse was defined by any of following: a) Worsening of depressive symptoms as indicated by MADRS total score greater than or equal to (>=) 22 confirmed by 1 additional assessment of MADRS total score >= 22 within the next 5 to 15 days. The date of the second MADRS assessment was used for the date of relapse; b) Any psychiatric hospitalization for: worsening of depression, suicide prevention or suicide attempt, the start date of hospitalization was the date of relapse; c) Suicide attempt, completed suicide, or any other clinically relevant event determined by investigator's judgment to be indicative of a relapse of depressive illness, but without hospitalized. The onset of the event was used for the date of relapse. |

Change From Baseline in Clinician-rated Overall Severity of Depressive Illness as Assessed by Clinical Global Impression - Severity (CGI-S) Scale Score |
Change from baseline in clinician-rated overall severity of depressive illness as assessed by CGI-S scale score was reported. The CGI-S provides an overall clinician-determined summary measure of the severity of the participant's illness that takes into account all available information, including knowledge of the participant's history, psychosocial circumstances, symptoms, behavior, and the impact of the symptoms on the participant's ability to function. The CGI-S evaluates the severity of psychopathology on a scale of 1 to 7. Considering total clinical experience, a participant is assessed on severity of mental illness at the time of rating according to: 1 = normal (not at all ill); 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; 7 = among the most extremely ill participants. Negative change in score indicates improvement. |

Change from baseline in participant-reported functional impairment and associated disability as assessed by SDS total score was reported. The SDS is a validated PRO measure consisting of a 5-item questionnaire that has been widely used and accepted for assessment of functional impairment and associated disability.

It also has 1 item assessing days lost from school or work and 1 item assessing days of underproductivity. The scores for the first 3 items are summed to create a total score of 0 to 30, where higher score indicates greater impairment. Scores <=2 for each item and <= 6 for the total score are considered functional remission. |

The SF-36 consists of 8 subscales (physical function, role limitations due to physical problems, pain, general health perception, vitality, social function, role limitations due to emotional problems, and mental health). Participants self-report on items in a subscale that have between 2-6 choices per item using likert-type responses (for example: none of the time, some of the time, etc.). Summations of item scores of the same subscale give the subscale scores, which are transformed into a range from 0 to 100; 0= worst HRQoL, 100=best HRQoL. Higher scores indicate better health status. |

Each of the 5 dimensions is divided into 5 levels of perceived problems (level 1 = no problem, level 2 = slight problems, level 3 = moderate problems, level 4 = severe problems, level 5 = extreme problems). The participant selects an answer for each of the 5 dimensions considering the response that best matches his or her health "today." Responses were used to generate health status index which ranges from 0 (dead) and 1 (full health), a lower score indicates worse health. |
