E.2.2 | Secondary objectives of the trial |
Responder rates whereby response is defined as at least 50% reduction of the MADRS total score between baseline and the individual last visit of the treatment period; Remission rates whereby remission is defined as total score of the MADRS below 10 points at the individual last visit of the treatment period. Change in the 17-HAMD total score between baseline and the individual last visit of the treatment period; Responder rates whereby response is defined as at least 50% reduction of the 17-HAMD total score between baseline and the individual last visit of the treatment period ; Remission rates whereby remission is defined as total score of the 17-HAMD below 8 points at the individual last visit of the treatment period Further outcome variables: MADRS single items, CGI, BDI, global rating of satisfaction with therapy result at individual last visit of the acute treatment period; SF 36, Sheehan Disability Scale. Safety and tolerability during the treatment

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is defined as: change from baseline (visit 2) to the individual last visit (visit 5 = day 57 or last day in study in case of premature termination) in the MADRS total score. For confirmatory analysis, the difference to day 57 (visit 5) or individual last visit in the treatment phase in case of premature termination will be considered. |
