Design outcomes

Primary

MeasureTime frame
Main Objective: The primary endpoint of the study is to ascertain if Betesil® medicated plaster is as effective as the reference drug, when applied daily during a period of maximum 4 weeks on psoriasis plaques localised at elbows and knees.;Secondary Objective: Secondary endpoints are: the evaluation of the products safety and the record of patient’s acceptability of the treatments.;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
