Primary outcome measures
- Incidence and severity grading of Adverse Events (AE)(applicable to Part 1) [Time frame: Up to Week 16 (applicable to the Q4W dosing group); Up to Week 8 (applicable to the Q2W dosing group).]
- Percentage of patients who achieved Eczema Area and Severity Index (EASI)-75 (applicable to Part 2) [Time frame: at week 16]
Secondary outcome measures (4)

- Percentage change in affected Body Surface Area (BSA) [Time frame: Up to week 24]
- Percentage change of Peak Pruritus Numerical Rating Scale (P-NRS) scores [Time frame: Up to week 24]
- Percentage changes in the Dermatology Life Quality Index (DLQI) score [Time frame: Up to week 24]
