Key clinical point: Topical Streptococcus postbiotic emollient (strain CX) demonstrated superior efficacy in improving disease activity outcomes and a tolerable safety profile in patients with mild-to-moderate atopic dermatitis (AD).
Major finding: At week 8, a higher percentage of patients in the topical Streptococcus postbiotic emollient vs placebo group (41.5% vs 12.1%; P = .005) achieved an Investigator’s Global Assessment score of 0 or 1 and a reduction of ≥1 point from baseline. No significant safety issues were identified during the study.
Study details: Findings are from a proof-of-concept trial including 98 patients with mild-to-moderate AD (age 12-70 years) who were randomly assigned 2:1 to receive daily topical 1.0% Strain CX postbiotic emollient (n = 65) or placebo (n = 33) for 8 weeks.
Disclosures: This study was supported by the National Research Foundation of Korea grant funded by the Korea government and Cosmax BTI. The authors declared no conflicts of interest.
