Official Title: “Calcipotriol Plus Betamethasone Dipropionate Gel Compared to Betamethasone Dipropionate in the Gel Vehicle and Calcipotriol in the Gel Vehicle in Scalp Psoriasis”

The purpose of the study is to evaluate whether once daily topical treatment for up to 8 weeks of calcipotriol 50 mcg/g plus betamethasone 0.5 mg/g (as dipropionate) gel is safe and more effective than betamethasone 0.5 mg/g (as dipropionate) in the gel vehicle and calcipotriol 50 mcg/g in the gel vehicle in patients with scalp psoriasis.

The primary response criterion is the number of patients with absence of disease and very mild disease after 8 weeks of treatment.

Study Type: Interventional

Study Design: Treatment, Randomized, Double-Blind, Active Control, Parallel Assignment, Safety/Efficacy Study

Secondary Measures

• - Total sign score at week 8
• - Score for scaliness, redness and thickness at week 8
• - Patients with "Controlled disease" ("Absence of disease" or "Very mild disease") according to investigator's global assessment of disease severity at week 2 and 4
• - Patients with "Treatment success" ("Almost clear" or "Cleared") according to patient's overall assessment of disease severity at week 8
• - Evaluation of Adverse Events
• - Evaluation of Laboratory Data
