METHODS: Patients aged ≥18 years with mild–severe psoriasis were enrolled into three Phase II/III studies (nCT01536886, nCT01536938, nCT01866163); each study evaluated Cal/BD aerosol foam versus different comparators. Endpoints included: proportion of patients clear/almost clear with ≥2-step improvement in physician's global assessment of disease severity (‘treatment success’); modified (excluding head) psoriasis area and severity index (mPASI); proportion of patients with ≥75% reduction in mPASI (PASI75); change in itch (according to visual analog scale [VAS]).
RESULTS: 1104 patients were included in the pooled analysis: Cal/BD aerosol foam (n=564), Cal/BD ointment (n=135), BD aerosol foam (n=101), Cal aerosol foam (n=101), aerosol foam vehicle (n=152), ointment vehicle (n=51). At week 4, 51% of Cal/BD aerosol foam patients achieved treatment success, a higher proportion than in all other groups (Cal/BD ointment, 43%; BD aerosol foam, 31%; Cal aerosol foam, 15%; aerosol foam vehicle, 5%; ointment vehicle, 8%). Greater percentage mean decrease in mPASI with Cal/BD aerosol foam was noted versus other treatments at week 4 (72% vs 63%, 53%, 43%, 32%, and 33%, respectively); week 4 PASI75 rate was also greater (51% vs 41%, 34%, 18%, 7%, and 10%, respectively). Cal/BD aerosol foam was efficacious irrespective of baseline disease severity and on all body areas assessed (arms, legs, trunk). Cal/BD aerosol foam alleviated itch as early as week 1 (change in itch VAS: –30 mm), maintained to week 4 (change in itch VAS: –41 mm).
CONCLUSIONS: Cal/BD aerosol foam was significantly more effective than Cal/BD ointment and the individual active ingredients for treating psoriasis vulgaris, resulting in greater and faster reduction in disease severity and rapid, effective relief of itch.
