Efficacy and safety of ruxolitinib cream in children aged 2 to 11 years with atopic dermatitis: Results from TRuE-AD3, a phase 3, randomized double-blind study.

Abstract

Ruxolitinib (Janus kinase 1 and Janus kinase 2 inhibitor) cream demonstrated efficacy and safety in adolescents and adults with mild-to-moderate atopic dermatitis (AD). To evaluate 8-week efficacy and safety of ruxolitinib cream in children with mild-to-moderate AD. This phase 3 study (TRuE-AD3; NCT04921969) enrolled children aged 2-11 years with an Investigator's Global Assessment (IGA) score of 2 or 3 and 3% to 20% affected body surface area. Patients were randomized 2:2:1 to twice-daily ruxolitinib cream (0.75% or 1.5%) or vehicle for 8 weeks. The primary endpoint was the proportion of patients achieving IGA treatment success (IGA-TS; score of 0/1 with ≥2-grade improvement from baseline) at Week 8. Children (N = 330) were randomized to vehicle (n = 65), 0.75% ruxolitinib cream (n = 134), or 1.5% ruxolitinib cream (n = 131). At Week 8, significantly more patients achieved IGA-TS with 0.75%/1.5% ruxolitinib cream (36.6%/56.5%) versus vehicle (10.8%; P = .0001/P < .0001). Improvements in itch and quality of life were also observed. The safety profile was consistent with that observed in adults and adolescents. Enrollment was limited to patients in North America. Ruxolitinib cream provided superior improvements versus vehicle in AD signs and symptoms in children with mild-to-moderate AD and was well tolerated.
