Incidence of treatment emergent adverse events (TEAEs) Timeframe: 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 outcomes 1. Eczema Area and Severity Index (EASI) score Timeframe: baseline 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. 2. Investigator's Global Assessment (IGA) 0/1 Timeframe: from 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). 3. Affected body surface area (BSA) score Timeframe: from 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. 4. Area under the curve(AUC) of AK120 Timeframe: before drug administration at week 0/4/8/12/16 Assessment of AUC of AK120. 5. Anti-drug antibodies (ADA) of AK120 Timeframe: before drug administration at week 0/4/8/16/20 Percentage of subjects with detectable anti drug antibodies (ADA) of AK120.

Male or female subjects aged ≥18≤75 years old. 2. Atopic dermatitis (AD) diagnosed at least half a year before screening. 3. Subject with EASI score ≥16, IGA ≥ 3, BSA ≥ 10% at screening and baseline. 4. Subjects who are suitable for continue using biological treatment assessed by investigator ### Exclusion criteria 1. Acute onset of AD within 4 weeks before drug administration. 2. The accompany disease have been assessed by the investigators during screening period as unsuitable for participation in this study. 3. Any history or symptoms of malignant tumors in any organ within 5 years prior to screening, regardless of whether treatment has been received and whether there are signs of recurrence or metastasis 4. Have a known or suspected history of immunosuppressive diseases, including a history of invasive infections. 5. Having undergone or planned major surgery within 4 weeks prior to drug administration, or unable to fully recover from surgery prior to drug administration. 6. any medical or psychological condition that puts subjects at risk or may affect the study results assessed by investigators.
