Efficacy and safety of tacrolimus ointment compared with that of hydrocortisone acetate ointment in children with atopic dermatitis.

摘要

BACKGROUND: Vehicle-controlled studies have demonstrated the efficacy and safety of tacrolimus ointment in the treatment of patients with atopic dermatitis (AD). OBJECTIVE: This study was undertaken to compare 0.03% and 0.1% tacrolimus ointment with 1% hydrocortisone acetate ointment in children 2 to 15 years of age with moderate-to-severe AD. METHODS: Treatment was twice daily to affected areas for 3 weeks in this multicenter, randomized, double-blind, parallel-group study. The primary endpoint was the modified eczema area and severity index (mEASI) mean area under the curve (mAUC) as a percentage of baseline. RESULTS: Five hundred sixty patients were randomized and received at least one application of ointment. Discontinuations included 21 of 189 patients from the 0.03% tacrolimus group, 13 of 186 patients from the 0.1% tacrolimus group, and 20 of 185 patients from the hydrocortisone acetate group. The median mEASI mAUC as a percentage of baseline showed 0.03% and 0.1% tacrolimus to be significantly more effective than 1% hydrocortisone acetate (P <.001) and 0.1% tacrolimus to be more effective than 0.03% tacrolimus (P =.006). The mEASI mAUC as a percentage of baseline was 44.8%, 39.8%, and 64.0% for patients who received 0.03% tacrolimus, 0.1% tacrolimus, and 1% hydrocortisone acetate, respectively. Transient skin burning was the only adverse event to show a higher incidence in the tacrolimus treatment groups than in the hydrocortisone acetate group (P <.05). Laboratory parameters showed no treatment differences and no marked changes over time. CONCLUSION: Tacrolimus, 0.03% and 0.1%, was significantly more effective than 1% hydrocortisone acetate and 0.1% tacrolimus was more effective than 0.03% tacrolimus in the treatment of moderate-to-severe AD in children. No safety concerns were identified.
