    AK139 plus placebo regimen 1-subcutaneous injection.
  • Biological AK139
    AK139 regimen 2-subcutaneous injection.
  • Biological AK139 and placebo
    AK139 plus placebo regimen 3-subcutaneous injection.
  • Biological AK139
    AK139 regimen 4-subcutaneous injection.
  • Biological AK139 and placebo
    AK139 plus placebo regimen 5-subcutaneous injection.
  • Biological AK139 and placebo
    AK139 plus placebo regimen 6-subcutaneous injection.
  • Biological Placebo
    Placebo-subcutaneous injection

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 of patients achieving an IGA score of 0 or 1 at each visit, with a reduction of ≥2 points from baseline [Time frame: Up to Week 24]
  • 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]

Eligibility criteria

Inclusion criteria

  • Able to understand the study and voluntarily sign the ICF.
  • Atopic dermatitis (AD) diagnosed at least 6 months before screening.
  • Eczema Area and Severity Index (EASI) score ≥16, Investigator's Global Assessment (IGA) score ≥3, and Body surface area (BSA) involvement ≥10% at both screening and baseline.
  • A weekly average of daily Peak Pruritus Numerical Rating Scale (P-NRS) score ≥4 at baseline.
  • Inadequate response or intolerance to prior topical therapy for AD.
  • The patients agree to use highly effective contraception methods from the moment of signing of the ICF to 90 days after the last dose of the investigational product.

Exclusion criteria

  • Acute onset of AD within the first 4 weeks of randomization.
  • Received systemic corticosteroids, immunosuppressive/immunomodulatory drugs, phototherapy or other systemic therapies used for AD within the 4 weeks before randomization.
  • Received treatment with other clinical research drugs (non-biological agents) within the first 4 weeks or 5 half-lives of randomization (whichever is longer)
  • Received or planned to receive live vaccine treatment within the 12 weeks before randomization or during the study period.
  • Received allergen specific immunotherapy within the 12 weeks before randomization.
  • Have a history of allergies to any component of AK139 and/or severe allergic reactions to monoclonal antibodies.
