2. Chronic AD for at least 1 year based on clinically confirmed diagnosis of active AD, according to Hanfin and Rajka criteria.
3. Participants with moderate-to-severe AD defined by:

   1. Investigator global assessment (IGA) score of ≥ 3 (on a scale of 0 to 4, in which three is moderate and four is severe) at Screening and Baseline.

   3. EASI score of ≥ 16 at Screening and at Baseline.
   4. Peak pruritus numerical rating scale (PP-NRS) ≥ 4 at Baseline. Note: The PP-NRS will be calculated from the 7 consecutive days immediately preceding Baseline. A minimum of 4 daily scores out of the 7 days is needed.
4. Participants who are candidates for systemic therapy, defined as history of inadequate response to topical AD treatments applied for at least 28 days, or for the maximum duration recommended by the product prescribing information, or for treatment with topical AD treatments is medically inadvisable due to important side effects or safety risks.

3. Participant has a current diagnosis of other active skin disease (e.g., psoriasis or lupus erythematosus) or skin infection (bacterial, fungal, or viral) that may affect the evaluation of AD or would interfere with the study assessments based on the Investigator's judgement.
4. Participant has history of significant flares of AD within 4 weeks prior to screening, in the opinion of the investigator.
5. Participant has a severe comorbidity that may require systemic steroids therapy or other interventions or requires active frequent monitoring (e.g., unstable chronic asthma) based on investigator judgement.

    4. Systemic therapies (other than biologics) that could affect AD not noted above, within 4 weeks prior to Baseline, including but not limited to, retinoids, calcineurin inhibitors, methotrexate, hydroxycarbamide (hydroxyurea), azathioprine, oral/injectable corticosteroids. Note: Intranasal corticosteroids and inhaled corticosteroids are allowed. Eye and ear drops containing corticosteroids are also allowed.
    5. Treatment with any investigational biologic agent or biologic agent approved after publication of this protocol, within 12 weeks (or 5 half-lives, whichever is greater) of screening.
    6. Treatment with any investigational nonbiologic agent, or any investigational device or procedure, within 4 weeks (or 5 half-lives, whichever is greater) of screening.
