Effectiveness and safety of a prevention‐of‐flare‐progression strategy with pimecrolimus cream 1% in the management of paediatric atopic dermatitis

Abstract

This study was performed to investigate the efficacy and safety of a prevention-of-flare-progression strategy with pimecrolimus cream 1% in children and adolescents with atopic dermatitis (AD). A 26-week multi-centre, randomized, double-blind, vehicle-controlled study was conducted in 521 patients aged 2-17 years, with a history of mild or moderate AD, who were clear/almost clear of disease before randomization to pimecrolimus cream 1% (n = 256) or vehicle cream (n = 265). Twice-daily treatment with study medication was started at the first signs and/or symptoms of recurring AD. If, despite the application of study medication for at least 3 days, AD worsened (as confirmed by the investigator), treatment with a moderately potent topical corticosteroid (TCS) was allowed in both groups. The primary efficacy end point was the number of days on study without TCS use for a flare. The mean number of TCS-free days was significantly higher (P < 0.0001) in the pimecrolimus cream 1% group (160.2 days) than in the control group (137.7 days). On average, patients on pimecrolimus cream 1% experienced 50% fewer flares requiring TCSs (0.84) than patients on vehicle cream (1.68) (P < 0.0001). Patients on pimecrolimus cream 1% also had fewer unscheduled visits (87) than patients on vehicle cream (246). In children and adolescents with a history of mild or moderate AD but free/almost free of signs or symptoms of the disease, early treatment of subsequent AD exacerbations with pimecrolimus cream 1% prevented progression to flares requiring TCS, leading to fewer unscheduled visits and reducing corticosteroid exposure.
