Calcipotriol plus betamethasone dipropionate aerosol foam vs. apremilast, methotrexate, acitretin or fumaric acid esters for the treatment of plaque psoriasis: a matching‐adjusted indirect comparison

Background Plaque psoriasis has significant impact on patients’ quality of life. Topical therapy is considered the treatment mainstay for mild‐to‐moderate disease according to guidelines. Calcipotriol/betamethasone dipropionate (Cal/BD) [0.005%/0.05%] aerosol foam is indicated for psoriasis vulgaris treatment in adults. Cal/BD foam trials demonstrated improved efficacy and similar safety in this population. Psoriasis treatment is complicated by the broad range of disease presentation, variability and therapeutic options; particularly decisions on transition from topical to non‐biologic systemic treatment are difficult. Assessing comparative effectiveness of treatment options provides meaningful value to treatment decisions. Objective To compare efficacy of Cal/BD foam individual patient data from pooled trials with efficacy of non‐biologic systemic treatments based on aggregated patient characteristics and treatment outcomes. Methods Individual data from four Cal/BD foam trials in 749 psoriasis patients were pooled to conduct matching‐adjusted indirect comparisons. Literature review identified non‐biologic systemic treatment trials where methods, populations and outcomes align with Cal/BD foam trials. Of 3090 screened publications, four studies of apremilast, methotrexate, acitretin or fumaric acid esters (FAE) were included. Results After baseline matching, patients treated with 4 weeks of Cal/BD foam had greater Physician's Global Assessment 0/1 response compared to those treated with 16 weeks of apremilast (52.7% vs. 30.4%; P
