Reduction in itch after first dose (as measured at Week 3)

6 MONTHS TO 5 YEARS

Significant itch reduction
(≥4-point improvement in
Worst Scratch/Itch NRS)
with DUPIXENT + TCS at
Week 16 in AD-1539
(secondary endpoint)1‑3,a,b

Definitive conclusions cannot be made for time points earlier than Week 16 as those data were not multiplicity controlled and P value was nominal.

bIn the primary analyses of the efficacy endpoints, subjects who received rescue treatment or with missing data were considered nonresponders.1

Worst Scratch/Itch NRS assesses the average itch intensity over the previous 24 hours4

It is a patient-reported measure that uses a 0- to 10-point scale, with which caregivers of infants to preschoolers aged 6 months to 5 years were asked:

“How would you rate your child’s scratching/itching at its worst in the past 24 hours?”
