Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject has provided informed consent prior to initiation of any study specific activities/procedures.
• Age greater than or equal to 18 to less than or equal to 75 years at screening.
• Clinical diagnosis of chronic AD (also known as atopic eczema) for at least 2 years prior to screening and has confirmed AD (Hanifin and Rajka criteria for AD (Hanifin and Rajka, 1980).
• AD that affects greater than or equal to' 10% body surface area as assessed by EASI at screening and on day 1.
• An IGA score of greater than or equal to 3 at screening and on day 1.
• An EASI score of greater than or equal to 16 at screening and on day 1.
• Subject discontinued treatment with TCS, topical calcineurin inhibitors (TCI), and prescription moisturizers containing TCS or topical calcineurin inhibitors (TCI) for at least the 7 days immediately prior to the first dose of investigational product
• Documented recent history (within 12 months before the screening visit) of inadequate response totreatment with topical TCS or subjects for whom topical treatments are otherwise medically inadvisable (ie, because of important side effects or safety risks).
• Inadequate response is defined as failure to achieve and maintain remission or a low disease activity state (comparable to IGA 0 = clear to IGA 2 = mild) despite treatment with a daily regimen of TCS of medium or higher potency (with or without TCI as appropriate).

You may not qualify if…

• Active dermatologic conditions, which might confound the diagnosis of AD or would interfere with the assessment of treatment, such as scabies, seborrheic dermatitis, cutaneous lymphoma, ichthyosis, psoriasis, allergic contact dermatitis, or irritant contact dermatitis.
• History of a clinically significant infection within 28 days prior to day 1 that, in the opinion of the investigator or medical monitor, might compromise the safety of the subject in the study, interfere with evaluation of the investigational product, or reduce the subject's ability to participate in the study. Clinically significant infections are defined as either of the following: 1) a systemic infection; or 2) a serious skin infection requiring parenteral antibiotic, antiviral, or antifungal medication.
• Diagnosis of a helminth parasitic infection within 6 months prior to screening that had not been treated with or had failed to respond to standard of care therapy.
• Documented medical history of chronic alcohol or drug abuse within 12 months prior to screening.
• History of anaphylaxis following any biologic therapy.
• Evidence of active liver disease at screening, including jaundice or aspartate aminotransferase (AST), alanine aminotransferase (ALT), or alkaline phosphatase greater than twice the upper limit of normal (ULN).
• Subjects who, in the opinion of the investigator, have evidence of active tuberculosis (TB), either treated or untreated, or a positive QuantiFERON-tuberculosis Gold (QFT-G) test for TB during screening. Subjects with an indeterminate QFT-G may be enrolled if they have ALL of the following:
• No symptoms of TB: productive, prolonged cough (> 3 weeks); coughing up blood; fever; night sweats; unexplained appetite loss; unintentional weight loss
• No evidence of active TB on chest radiograph within 3 months prior to the first dose of investigational product. Note: Chest radiograph is not part of screening procedure and will be the responsibility
• Positive hepatitis B surface antigen or hepatitis C antibody serology. Subjects with a history of hepatitis B vaccination without a history of hepatitis B are allowed to enroll in the study.
• Positive human immunodeficiency virus (HIV) test at screening or the subject is taking antiretroviral medications, as determined by medical history, prior medications, and/or the subject's verbal report.
• Other Medical Conditions>
• History of malignancy, except for basal cell carcinoma or in situ carcinoma of the cervix treated with apparent success with curative therapy ≥ 12 months prior to screening or other malignancies treated with apparent success with curative therapy ≥ 5 years prior to screening.
• History or evidence of severe depression, schizophrenia, previous suicide attempts, or suicidal ideation.
• Prior/Concomitant Therapy:
• Subjects who are unwilling to abstain from the use of TCS, TCI, and prescription moisturizers (those that contain TCS and TCI) from screening through week 16 (applies only to Part A subjects)
• Subjects who have had side effects of topical medications including intolerance to treatment, hypersensitivity reactions, significant skin atrophy, or systemic effects as assessed by the investigator or by the subject's treating physician (applies only to Part B subjects)
• More than or equal to 30% of the total lesional surface is located on areas of thin skin that cannot be safely treated with medium or higher potency TCS (eg, face, neck, intertriginous areas, areas of skin atrophy) (applies only to Part B subjects)
• Receipt of any approved biologic agent (eg, dupilumab) within 4 months or 5 elimination half-lives (whichever is longer) prior to screening
• Have used immunosuppressive/immunomodulating drugs (eg, systemic corticosteroids, cyclosporine, mycophenolate-mofetil, interferon (IFN)-gamma, Janus kinase inhibitors, azathioprine, methotrexate) within 4 weeks prior to screening, or any condition that, in the opinion of the investigator, is likely to require such treatment(s) during the first 4 weeks of study treatment.
• Have had phototherapy for AD in the 2 months prior to day 1, and subjects unwilling to avoid phototherapy during the first 16 weeks of the study
• If on allergen-specific immunotherapy, subjects must be on a maintenance dose and schedule for ≥ 28 days prior to screening. Allergen-specific immunotherapy is defined as SC immunotherapy to aeroallergens and/o venom (Hymenoptera) as well as sublingual immunotherapy to aeroallergens
• Vaccination with a live or attenuated vaccine within 28 days prior to day 1. Receipt of inactive/killed vaccinations (eg, inactive influenza) is allowed. Note that receipt of the Th2 cytokine inhibitor suplatast within 15 days prior to randomization and during the study is not allowed.
• Major surgery within 8 weeks prior to screening or planned inpatient surgery or hospitalization during the study period
• Currently receiving treatment in another investigational device or drug study, or less than 6 months since ending treatment on another investigational device or drug study(ies). Other investigational procedures while participating in this study are excluded.
