Fixed combination calcipotriol as hydrate (Cal) 50g/g plus betamethasone as dipropionate (BD) 0.5mg/g aerosol foam is an alcohol-free treatment for psoriasis. Betamethasone 17-valerate 2.25mg (BV)-medicated plasters are recommended for treating psoriasis plaques localized in difficult-to-treat (DTT; elbow, knee, anterior face of the tibia) areas.The aim of this study was to compare the efficacy of Cal/BD foam with BV-medicated plaster in patients with plaque psoriasis.In this phase IIa, randomized, single-center, investigator-blinded, 4-week study, both Cal/BD foam and BV-medicated plaster were applied once daily to six test sites (three for each treatment). The primary efficacy endpoint was absolute change in total clinical score (TCS; sum of erythema, scaling, and infiltration); secondary endpoints were changes from baseline in each individual clinical score, ultrasonographic changes (total skin and echo-poor band thickness), and safety; and post hoc analysis was change from baseline in TCS on DTT areas.Thirty-five patients were included. Least-squares mean change in TCS from baseline was significantly greater for Cal/BD foam (-5.8) than BV-medicated plaster (-3.7; difference -2.2; 95% confidence interval -2.6 to -1.8; p<0.001); greater changes for Cal/BD foam were observed from day8 for each clinical sign. Absolute total skin and echo-poor band thickness change was significantly greater for Cal/BD foam than for BV-medicated plaster (both p<0.001). Post hoc analyses showed that Cal/BD foam was significantly more effective than BV-medicated plaster on DTT areas after 4weeks (p<0.001), and both treatments were well tolerated.Cal/BD foam demonstrated superior efficacy versus BV-medicated plasters, including on DTT areas, in patients with plaque psoriasis.NCT02518048.
