    CGI-Severity of illness and CGI-Global improvement at Visit 6/final visit

  • Changes in evaluation of sleep quality and sexual dysfunction [ Time Frame: Six weeks ] [ Designated as safety issue: Yes ]
    change from baseline in evaluation of sleep quality and sexual dysfunction at Visit 6/final visit

  • Rate changes of responders/patients [ Time Frame: Six weeks ] [ Designated as safety issue: Yes ]
    rate of responders, defined as patients with a 50% improvement from baseline in the HAMD score at Visit6/final visit;or rate of patients with remission, defined as patients with HAMD score ≤7 at Visit 6/final visit.
