Addition of topical pimecrolimus to once-daily mid-potent steroid confers no short-term therapeutic benefit in the treatment of severe atopic dermatitis; a randomized controlled trial

Abstract

Background: Combination therapy with pimecrolimus cream 1%, a topical calcineurin inhibitor (TCI), and fluticasone propionate cream 0.05% (FP), a mid-potency topical corticosteroid, may have a synergistic effect for treatment of atopic dermatitis (AD) because their mechanism of action differs.

Objectives: To assess the efficacy of concomitant pimecrolimus twice daily/FP once daily vs. vehicle twice daily/FP once daily in patients with severe AD.

Methods: An exploratory, 2-week, double-blind, randomized, within-patient study was conducted (n = 45). Two target areas of similar severity, size and location were assessed. Assessments included the modified Eczema Area and Severity Index (0-12 scale) (primary variable), localized investigator global assessment (0-4 scale) and Patients' Self-Assessment of Disease Severity (0-4 scale).

Results: Data for all variables were similar for the TCI/FP and vehicle/FP treatments.

Conclusions: The efficacy observed for treatment of severe AD flares with this TCI/FP combination regimen was equivalent to that of vehicle/FP.
