LEO 80185 in the Treatment of Psoriasis Vulgaris on the Non-scalp Regions of the Body (Trunk and/or Limbs)

The purpose of this study is to compare the efficacy and safety of Calcipotriol 50 Mcg/g Plus Betamethasone 0.5 mg/g (as Dipropionate) Topical Suspension with the active components when used individually as monotherapy in the topical suspension vehicle (betamethasone dipropionate in the topical suspension vehicle, calcipotriol in the topical suspension vehicle) and with the topical suspension vehicle alone in the treatment of psoriasis vulgaris on the non-scalp regions of the body (trunk and/or limbs) in a large phase 3 study. This comparison will ensure a more informed assessment of the benefit/risk ratio of Calcipotriol 50 Mcg/g Plus Betamethasone 0.5 mg/g (as Dipropionate) Topical Suspension while also establishing the optimal treatment duration in psoriasis vulgaris on the non-scalp regions of the body (trunk and/or limbs).
