  • •validated Investigator Global Assessment Scale for Atopic Dermatitis (vIGA-AD) score greater than or equal to 3 at screening and baseline.
  • •Body Surface Area (BSA) of AD involvement greater than or equal to 10% at screening and baseline.

Exclusion Criteria

  • •Major surgery within 8 weeks prior to screening, or planned inpatient surgery or hospitalization during the trial period
  • •Active dermatologic condition that could confound the diagnosis of AD or interfere with assessment of the treatment (e.g. scabies, contact dermatitis, rosacea, urticaria, or psoriasis)
  • •History of cancer, with the following exceptions:
  • •Subjects who have had basal cell carcinoma, localized squamous cell carcinoma of the skin or in situ carcinoma of the cervix are eligible provided that the subject is in remission and curative therapy was completed at least 12 months prior to screening.
  • •Subjects who have had other malignancies are eligible provided that the subject is in remission and curative therapy was completed at least 5 years prior to screening
  • •History of or current immunodeficiency syndrome.
  • •History of anaphylaxis following any biologic therapy
  • •History of clinically significant infection within 4 weeks prior to baseline which, in the opinion of the investigator, may compromise the safety of the subject in the trial, interfere with evaluation of the IMP, or reduce the
  • •subjects ability to participate in the trial.
  • •Skin infection within 7 days prior to baseline
  • •Positive HBsAg or positive anti-HCV AND positive HCV RNA at screening.
  • •History of HIV infection or positive HIV serology at screening.

  • •Impede the subjects ability to complete the trial.
  • •Any significant abnormal finding at screening and or baseline which may, in the opinion of the investigator:

  • •Use of tanning beds or phototherapy, within 4 weeks prior to baseline.
  • •Receipt of blood products within 28 days prior to screening.
  • •Treatment with:
  • •Any marketed or investigational biologic agents within 3 months or 5 half-lives, whichever is longer, prior to baseline.
  • •Any cell-depleting agents including but not limited to rituximab: within 6 months prior to baseline, or until lymphocyte count returns to normal, whichever is longer.
