INTRODUCTION
The sequential use of the topical vitamin D analog, calcipotriene, and the topical corticosteroid, betamethasone dipropionate, is well established for the treatment of psoriasis; and the 2 agents used in combination have been shown to provide greater benefit than either monotherapy.1,2,3
Fixed combinations of calcipotriene and betamethasone dipropionate (Cal/BD) are available in ointment, foam, and topical suspension formulations. A Cal/BD aerosol foam formulation (Enstilar, LEO Pharma) is well established in the market. In clinical trials for psoriasis, Cal/BD aerosol foam was significantly more effective than either Cal/BD ointment or the individual active ingredients, providing greater and faster reduction in disease severity. Cal/BD foam was also associated with rapid itch reduction.4 Based on a review of data across studies, a panel of experts has suggested that Cal/BD aerosol foam presents an effective, safe, and cost-effective option for management of psoriasis that is beyond mild.5
A newer topical fixed combination formulation of calcipotriene 0.005% and betamethasone dipropionate 0.064% in a cream base (Wynzora® Cream, EPI Health/MC2 Therapeutics) is now available on the market. It features a specialized multimolecular technology (Polyaphron Dispersion [PAD™] Technology) that encapsulates the active ingredients in microscopic oil droplets suspended in an aqueous vehicle. In clinical trials, Cal/BD cream outperformed Cal/BD topical suspension (TS) in terms of Physicians Global Assessment (PGA) and mean psoriasis area and severity index (PASI) improvement at week 8. Cal/BD cream was well tolerated, with no adverse event reported with a frequency greater than 1%.6 In the pivotal trials, patients expressed a preference for the Cal/BD cream formulation, indicating that it was more convenient than the topical suspension.7
The current study is intended to investigate comparative patient satisfaction between Cal/BD foam and Cal/BD cream formulations.
