Primary Outcome Measures :
  1. Time to First Relapse During Double-blind Treatment Period [ Time Frame: Randomization (Week 18) to End of Treatment (Week 44) ]

    Time to Relapse is the number of days from randomization to first relapse.

    Relapse is defined as any 1 of the following:

    • Increase in Positive and Negative Syndrome Scale(PANSS) by ≥30% for participants who had total score of ≥50 at randomization or ≥10-point increased score with total score <50 at randomization [PANSS=30 questions where 1=absence of symptoms to 7=extremely severe symptom;total score=30 to 210;higher score more severe symptoms]
    • Increase in Clinical Global Impression-Severity (CGI-S) score by 2 or more points [1=normal to 7=among most extremely ill]
    • Score of >4 on 1 or more of 7 PANSS items:P1-delusions,P2-conceptual disorganization,P3-hallucinatory behavior,P6-suspiciousness,P7-hostility,G8-uncooperativeness,G14-poor impulse control
    • Deliberate self-injury
    • Initiation of treatment with mood stabilizer,antidepressant,antipsychotics or benzodiazepine that exceeds specified allowance
    • Psychiatric hospitalization
    • Exacerbation of psychiatric illness
