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

OBJECTIVE: 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). METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

Pimecrolimus cream 1% in the long-term management of adult atopic dermatitis: prevention of flare progression. A randomized controlled trial.

BACKGROUND: Previous studies suggested that early intervention with pimecrolimus cream 1% at the first signs and/or symptoms of a relapse of atopic dermatitis (AD) following remission may prevent the occurrence of more severe flares and therefore reduce corticosteroid exposure in the long term. However, this possibility was not rigorously evaluated. OBJECTIVES: To evaluate the effectiveness of pimecrolimus cream 1% for the prevention of flare progression in adults with AD. METHODS: A 26-week randomized controlled study was conducted in 543 patients aged>or=18 years, with a history of mild or moderate AD, who were clear/almost clear of disease before randomization to pimecrolimus cream 1% (n=277) or matching vehicle cream (n=266). Twice-daily treatment with study medication was started at the onset of the first signs and/or symptoms of a relapse. If disease worsened, despite the application of study medication for at least 3 days, treatment with a moderately potent topical corticosteroid (TCS) was allowed in both groups. The primary efficacy endpoint was the number of days without TCS use for disease worsening. RESULTS: The mean number of TCS-free days was significantly higher (P<0.001) in the pimecrolimus cream 1% group (152 days) than in the vehicle cream group (138.7 days). In comparison with vehicle cream, pimecrolimus cream 1% reduced the mean number of flares requiring TCS use from 1.39 to 0.97 (P=0.0014). Patients on pimecrolimus cream 1% made 30% fewer unscheduled visits (156) than patients on vehicle cream (223). CONCLUSIONS: In adults with a history of mild or moderate AD but free of active skin lesions, intervention with pimecrolimus cream 1% at the first signs and/or symptoms of a subsequent recurrence reduces the number of flares requiring TCS use and decreases the number of disease-related office visits.
