First experience of topical SDZ ASM 981 in children with atopic dermatitis

Br J Dermatol. 2001 Apr;144(4):781-7. doi: 10.1046/j.1365-2133.2001.04133.x.


Background: SDZ ASM 981 is a selective inhibitor of inflammatory cytokine release under development for the topical treatment of atopic dermatitis.

Objectives: This first paediatric study was designed to measure the systemic exposure to SDZ ASM 981 in young children with atopic dermatitis treated on extensive skin areas.

Methods: Children 1-4 years of age referred to a tertiary care centre for their atopic dermatitis were treated twice daily for 3 weeks with 1% SDZ ASM 981 cream. SDZ ASM 981 blood concentrations were measured on day 4 and 22 (last day) of treatment, and 1 week after the last application, using a radioimmunoassay with a limit of quantification of 0.5 ng mL(-1). Efficacy was assessed by the Eczema Area Severity Index (EASI).

Results: The 10 patients included had 23-69% of their body surface area (BSA) affected at baseline. Of the 63 SDZ ASM 981 blood concentrations measured, 63% were < 0.5 ng mL(-1); the maximum value observed was 1.8 ng mL-1. No accumulation was evidenced between days 4 and 22. The first two patients experienced a flare of atopic dermatitis that was not controlled by the study medication. In the other patients, the EASI improved by 8-89% at 3 weeks of treatment.

Conclusions: In these children 1-4 years of age, blood concentrations of SDZ ASM 981 during topical treatment with the 1% cream were consistently low even in the children with the most extensive areas treated (up to 69% of their BSA).
