    Abstract:
    BACKGROUND: Calcipotriene ointment and cream are effective treatments for psoriasis, but many patients with scalp psoriasis prefer lighter, less messy vehicles. OBJECTIVES: To evaluate the efficacy and safety of calcipotriene foam, 0.005%, for plaque-type psoriasis of the scalp. METHODS: Subjects (n=363) were randomized into an 8-week, multicenter, double-blind, vehicle-controlled, parallel-group, phase 3b study of calcipotriene foam, 0.005% (NCT01139580). Primary end point was the proportion of subjects with an Investigator's Static Global Assessment (ISGA) score of 0 (clear) or 1 (almost clear) at week 8 for scalp involvement. Body involvement, target lesion score, and improvement for erythema, scaling, and plaque thickness were also assessed.<BR> RESULTS: At week 8, more subjects in the calcipotriene foam, 0.005% group (40.9%) met the primary end point vs the vehicle foam group (24.2%; intent-to-treat [ITT] population; P <.001); a significant difference between groups was also observed at weeks 2 (P = .041) and 4 (P <.001). No significant difference was observed between treatment groups for ISGA of body psoriasis (ITT population; P = .544). In the per-protocol population, but not the ITT population, more subjects in the calcipotriene foam, 0.005%, group than the vehicle foam group met the secondary end points for scaling (P = .019) and plaque thickness (P =.027). Incidence of adverse events in both treatment groups was low; calcipotriene foam, 0.005%, was associated with erythema. LIMITATIONS: An 8-week study provides limited safety and efficacy data.<BR> CONCLUSION: Calcipotriene foam, 0.005%, was more effective than vehicle foam for improving scalp psoriasis over an 8-week period, with improvements evident from week 2, and had a similar safety profile to vehicle foam.
