Primary Outcome Measures :
  1. Mean Change From Randomization at the End of the Treatment Phase in the MADRS Total Score [ Time Frame: Week 0 (Randomization) and Week 10 ]
    The MADRS scale measures the depression level of a participant. The total score was derived by adding the scores of the following 10 items: 1, apparent sadness; 2, reported sadness; 3, inner tension; 4, reduced sleep; 5, reduced appetite; 6, concentration difficulties; 7, lassitude; 8, inability to feel; 9, pessimistic thoughts; 10, suicidal thoughts. Each item was scored using a scale of 0 to 6 (a higher score indicates increased severity). The maximum total score is 60; 0, no depression; 60, severely depressed. Randomization value was defined as the assessment value done on Week 0. Change from Randomization in total score was the difference between MADRS total score at the time point being analyzed (Week 10) to Randomization.

    The HAMD is a rating instrument for evaluating severity of symptoms of depression, was completed by the participant. The rating instrument used in this study was the 17-item version (HAM-D17). The Bech scale of the HAMD-17 is composed of 6 identified items out of the 17 items rated in HAMD-17 scale. Each item is rated on either a 3-point scale (0 to 2) or a 5-point scale (0 to 4). The following symptoms were rated on a 5-point scale (0-4): depressed mood, feeling of guilt, work and interests, psychomotor retardation, and anxiety (psychic). The following symptom was rated on a 3-point scale (0-2): somatic symptoms (general). Total score ranged from 0 to 22, with 0 indicating absence of symptoms and a higher score indicating greater severity of symptoms. Randomization value was defined as the assessment value done on Week 0. Change from Randomization in total score was the difference between Bech total score at the time point being analyzed (Week 10) to Randomization.

    CSSRS is a clinician-rated scale that evaluates severity and change of suicidality by integrating both behaviour and ideation. For SB scale, participants were scored as "non-suicidal" (00), "preparatory acts or behavior communicating ideation" (01), "aborted attempt" (02), "interrupted attempt" (03) or "actual attempt" (04) based on the most severe score (4 being the most severe). On SI scale, participants were scored as "non-suicidal" (00), "wish to be dead" (01), "non-specific active suicidal thoughts" (02), "active suicidal ideation with associated thoughts of methods without intent" (03), "active suicidal ideation with some intent to act on suicidal thoughts without clear plan" (04), "active suicidal ideation with plan and intent" (05), based on the most severe score (5 being the most severe). For both subscales, 0 indicated absence of symptom and higher score indicated greater severity of symptom. Only those scores for which at least one participant was reported are summarized.
