Study for Treatment With Calcipotriol/Betamethasone Dipropionate Gel in Korean Patients With Psoriasis Vulgaris

• Status: Completed
• Trial end date: 2014-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The combination of calcipotriol and betamethasone dipropionate used in an ointment formulation (Daivobet® ointment) has shown to have an excellent efficacy and safety in the short-term and long-term management of psoriasis vulgaris. A newly developed gel formulation (Xamiol® gel) of calcipotriol and betamethasone dipropionate has recently been approved and marketed in Korea as a topical treatment of moderate to severe scalp psoriasis and non-scalp psoriasis vulgaris.

Xamiol® gel, the investigational product (IP) used in this study, prevents keratinization by normalizing the reproduction cycle of skin cells. It also relieves itching associated with psoriasis. Xamiol® gel was initially approved for treatment of moderate to severe scalp psoriasis and its label was extended to non-scalp psoriasis vulgaris in October 2012.

Since patient compliance is one of the important factors in achieving effective outcomes in the treatment of psoriasis, the once daily dosing of Xamiol® gel is expected to enhance compliance and treatment outcomes as well as to provide a safe and effective therapeutic option.
