E.5 End points |
E.5.1 | Primary end point(s) |
Total Severity Score (TSS) at 4-items, as evaluated by the Blind Assessor (the Principal Investigator or a designee) at the end of the treatment period (w4) will be considered as primary efficacy variable for this study. The results achieved in the two treatment groups will be compared statistically in order to assess the non-inferiority of the tested versus the reference treatment. Data will be analysed as ITT. |
