Who can join

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

You may qualify if…

Be an adult ≥18 and ≤ 75 years of age at the screening visit (Screening) with atopic dermatitis according to American Academy of Dermatology Consensus Criteria, (Eichenfield 2014)
Present for at least 1 year prior to the baseline visit (Baseline) with an inadequate response, in the judgement of the Investigator, to AD treatment with a topical regimen of corticosteroids, phosphodiesterase inhibitors or calcineurin inhibitors, or for whom topical treatments are otherwise medically inadvisable (eg, because of important side effect or safety risks)
Investigator Global Assessment (IGA) score ≥ 3 at Screening and Baseline.
Eczema Area and Severity Index (EASI) score ≥ 16 at Screening and Baseline
Body Surface Area (BSA) for total AD involvement ≥ 10% at Screening and Baseline
Able and willing to apply a stable dose of a bland emollient twice a day to affected areas for at least 7 days before Baseline and to continue for the duration of the study
Females of child-bearing potential (FCBP) and males who have not undergone a vasectomy must abstain from heterosexual activities or agree to use effective contraception throughout the entire study period.

You may not qualify if…

Have any of the following laboratory abnormalities at Screening:
Hemoglobin ≤ 90% of the lower limit of normal range (LLN)
White blood cell (WBC) below the LLN
Neutrophil count below the LLN
Platelet count below the LLN
Have undergone treatment with any of the following:
Topical agents such as corticosteroids, phosphodiesterase (PDE) inhibitors, Janus kinase (JAK) inhibitors, tacrolimus or pimecrolimus within 1 week prior to Baseline. Note that low to medium potency topical corticosteroids (TCS) are permitted after randomization to treat AD flares
Prior treatment with dupilumab or any antibody against IL-4Rα or IL-13
Systemic treatment for AD or other condition with steroids or other immunosuppressive/immunomodulating substances, e.g., cyclosporine, mycophenolate-mofetil, azathioprine, methotrexate or oral Janus kinase (JAK) inhibitors within 4 weeks prior to Baseline. Use of steroid inhalers and nasal corticosteroids is allowed.
Cell depleting agents, e.g. rituximab, within 6 months of Baseline or treatment with other biologics within 5 half-lives (if known) or 3 months prior to baseline visit, whichever is longer
Phototherapy (narrow band ultraviolet B [NBUVB], ultraviolet B [UVB], ultraviolet A1 [UVA1], psoralen + ultraviolet A [PUVA]), tanning beds, or any other light emitting device (LED), within 4 weeks of Baseline
≥ 2 bleach baths within 2 weeks of Baseline
Prescription emollient to treat AD (e.g. Atopiclair®, MimyX®, Epicerum®, etc.) within 2 weeks of Baseline
Any investigational drug within 30 days or within 5 half-lives, whichever is longer, before Baseline.
Live (attenuated) vaccine within 8 weeks of Baseline.
Treatment with systemic traditional Chinese medicine (TCM) or herbal medications within 4 weeks before Baseline or treatment with topical TCM or herbal medications within 1 week before Baseline visit
Have any of the following:
Infection requiring treatment with systemic antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 4 weeks before Baseline, or superficial skin infection, such as impetigo, within 2 weeks before the Baseline (subjects may be rescreened after the infection has resolved)
A history of parasitic infection (e.g. helminth), within 6 months of Baseline
Per investigator judgement, known or suspected history of immunosuppression within 6 months of Baseline, including a history of invasive opportunistic infections, such as aspergillosis, coccidioidomycosis, histoplasmosis, human immunodeficiency virus (HIV), listeriosis, pneumocystosis, or tuberculosis, despite infection resolution; or unusually frequent, recurrent or prolonged infections.
Any history of vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC)
A history of malignancy with the following exceptions: completely treated carcinoma in situ of cervix or non-metastatic squamous or basal cell carcinoma of the skin
Positive results at Screening for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb) or hepatitis C antibody with positive HCV RNA polymerase chain reaction; positive HIV serology at screening
An allergy to L-histidine, trehalose or Tween (polysorbate) 80
Women must not be pregnant, planning to become pregnant or breast-feed during the study
