  Purpose

The scalp is one of the most common affected sites in psoriatic patients as 79% of them have scalp involvement.It has also a psychological aspect with 31% of patients with scalp psoriasis indicating distress.

Topical agents remain the mainstay of treatment for scalp psoriasis. However, they are not always ideal because they might be inconvenient and messy to use, stain or damage hair.

The test shampoo, Clobetasol propionate Shampoo 0.05% (marketed in the USA under the tradename of Clobex®) was developed to provide the strongest available corticosteroid as a short-contact therapy in order to improve the chances of it being effective and reduce the potential for traditional side-effects.

The objective of this study is to compare subject's overall preference between Clobetasol propionate shampoo 0.05% and three other topical corticosteroids in the treatment of moderate to severe scalp psoriasis.

Primary Outcome Measures:
  • Percentage of Subjects Preffering Clobetasol Propionate Shampoo Better Than Comparator [ Time Frame: End of period II (up to 16 weeks) ]
    Subjects' Overall preference at the end of Period II. The purpose was to demonstrate a superiority of Clobetasol propionate shampoo 0.05% therapy compared to any of three other topical comparators, in terms of subject's overall preference: "C. propionate shampoo a lot better than the comparator",C. propionate shampoo a lillte bit better than the comparator", "Comparator a lot better than C. propionate shampoo", Comparator a lillte bit better than C. propionate shampoo". This was to be shown using a non parametric two-sided Wilcoxon rank Signed test, on Intention to Treat (ITT) population.
