A Study to Determine the Efficacy of Taclonex Topical Suspension as a Supplement to Non-biologic Systemic Therapy

Many patients with mild psoriasis are able to control disease symptoms with topical medications alone. There are a variety of topical options available, including corticosteroids, synthetic vitamin D3, vitamin A, coal tar, salicylic acid and a number of other products of varying efficacy. The combination topical suspension of calcipotriene 0.005% and betamethasone dipropionate 0.064% is a first-line treatment for moderate to severe psoriasis vulgaris and is FDA approved for use on the skin and scalp in adults 18 years and older. This treatment combines the pharmacological effects of calcipotriene hydrate as a synthetic vitamin D3 analog and betamethasone dipropionate as a synthetic corticosteroid. It is well tolerated and has a low rate of adverse events according to pooled safety data from 2700 patients who have used a calcipotriene/betamethasone combination in clinical trials. Calcipotriene/betamethasone topical suspension has also been shown to have a positive impact on patient quality of life, as seen in clinical trials utilizing patient reported outcomes such as the Dermatology Life Quality Index (DLQI) and Psoriasis Disability Index. Calcipotriene/betamethasone topical suspension is a therapy commonly used to treat patients with mild to moderate psoriasis. Currently, there have been no formal trials studying the efficacy of calcipotriene/betamethasone topical suspension used in conjunction with methotrexate or acitretin. In order to better understand the effectiveness of this treatment combination, we conducted a preliminary, open label, single arm prospective study to determine the benefit of adding betamethasone-calcipotriene topical suspension to ongoing systemic psoriasis therapy in subjects who do not have complete clearance of psoriasis on a single systemic agent alone.
