Primary Outcome Measures
NameTimeMethod
Incidence of treatment emergent adverse events (TEAEs)through study completion, an average of 25 weeks

An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered related to the study treatment

Secondary Outcome Measures
NameTimeMethod
Eczema Area and Severity Index (EASI) scorebaseline to week 20

Percentage change in EASI score from baseline. EASI score is to assesses the extent and severity of eczema in four body regions with the score ranges from 0 to 72. The higher the score, the more severe the eczema.

Investigator's Global Assessment (IGA) 0/1from baseline to week 20

Percentage of subjects who achieved 0/1 in the IGA. The IGA is an assessment instrument used in clinical studies to rate the severity of atopic dermatitis globally, based on a 5-point scale ranging from 0 (clear) to 4 (severe).

Affected body surface area (BSA) scorefrom baseline to week 20

Percentage change in BSA score from baseline. Body surface area affected by atopic dermatitis will be assessed for each section of the body (0-100%) and will be reported as a percentage of all major body sections combined.

Area under the curve(AUC) of AK120before drug administration at week 0/4/8/12/16

Assessment of AUC of AK120.

Anti-drug antibodies (ADA) of AK120before drug administration at week 0/4/8/16/20

Percentage of subjects with detectable anti drug antibodies (ADA) of AK120.
