Primary Outcome Measures
NameTimeMethod
Percentage of subjects who achieved Eczema Area and Severity Index (EASI)-75at week 18 (day 127)

At week 18, the percentage of subjects who achieved EASI-75 compared to baseline. The EASI score ranges from 0 (no eczema) to 72 (maximum severity).

Percentage of subjects with the Investigator's Global Assessment (IGA) score decrease of ≥ 2 pointsat week 18 (day 127)

At week 18, the percentage of subjects with the IGA score decrease of ≥ 2 points from baseline. The IGA is a five-point scale ranging from 0 to 4 ( 0 indicates clear, 4 indicates severe).

Secondary Outcome Measures
NameTimeMethod
Percentage change in affected Body Surface Area (BSA)week 0 to week 52

Percentage change in BSA from baseline.

percentage change of Peak Pruritus Numerical Rating Scale (P-NRS) scoresweek 0 to week 52

percentage change of P-NRS scores from baseline at each visit. The scale ranging from 0 to 10 ( 0=no itch; 10=worst itch imaginable).

Percentage changes in the Children's Dermatology Life Quality Index (CDLQI) scoreweek 0 to week 52

Percentage changes in the CDLQI score compared to baseline at each visit. The total score range from 0 to 30, with higher scores indicating a greater impact on the patient's quality of life.

Incidence of Adverse Events (AE)week 0 to week 52
