Title: A Multi-Center, Randomized, Double-Blind, Vehicle-Controlled, Bilateral Study of the Safety and Efficacy of Topically Applied AN2898 and AN2728 in the Treatment of Patients With Mild-to-Moderate Atopic Dermatitis
Brief Summary: The purpose of this study is to determine whether AN2898 and AN2728 ointments are safe and effective treatments for mild-to-moderate atopic dermatitis (AD).


Options:
A: Inclusion Criteria:

* Clinical diagnosis of atopic dermatitis that has been clinically stable for ≥1 month
* Total body surface area (BSA) of atopic dermatitis involvement ≤35%, excluding involvement of the face, scalp, and groin
* Presence of two (2) comparable target lesions
* Willing and able to apply study medications as directed, comply with study instructions, and commit to attending all visits
* Females of childbearing potential must use at least one highly effective method of birth control. Males with partners of childbearing potential should inform them of their participation in this clinical study and use highly effective methods of birth control during the study.

Exclusion Criteria:

* Concurrent or recent use of certain topical or systemic medications or phototherapy without a sufficient washout period
* Active or potentially recurrent dermatologic condition other than atopic dermatitis in the target lesion area that may confound evaluation
* Significant confounding conditions as assessed by study doctor
* History or evidence of allergies requiring acute or chronic treatment (except seasonal allergic rhinitis)
* Participated in any other trial of an investigational drug or device within 30 days or participation in a research study concurrent with this study
* Pregnancy or lactation
B: Inclusion Criteria:

* Diagnosis of atopic dermatitis
* Family history of atopy
* 3 to 18 months of age at baseline
* At least mild atopic dermatitis at baseline (investigator global assessment \[IGA\] greater or equal to 2)
* Clinical evidence of atopic dermatitis for no longer than 3 months

Exclusion Criteria:

* Diagnosis of or substantial clinical evidence for food or other allergies at baseline

Other protocol related criteria may apply

* Available to complete the whole trial
* Can use the inhalation device correctly
* Able to read, understand and write English

Exclusion criteria:

* Deemed suitable healthy subject
* History to sensitivity to the study medication
* Any history of breathing problems in adult life
* Participated in another trial within 30 days or 5 half-lives of the new chemical entity
* Exposed to more than 4 new chemical entities within 12 months
* Donated \>500 mL blood within 2 months of screening
* Haemoglobin level \< 13g/dl
* Use of prescription or non-prescription drugs within 7 days of first dose
* Taking drugs that significantly inhibit cytochrome P450 subfamily enzyme CYP3A4
* Drinks more than 4 units a day or 28 units a week
* Cannot use DISKHALER device correctly
* Positive HepB, HepC within 3 months of screening
* Positive HIV test
* Positive pre study drug/alcohol screen
* Significant cardiac conduction abnormalities
* Risk of non-compliance
D: Inclusion Criteria:

* Participants diagnosed with atopic dermatitis (AD) as defined by the Hanifin and Rajka criteria.
* Participants with a history of AD for at least 2 years.
* Participants with an Investigator's Global Assessment (IGA) score of 2 to 3 at screening and baseline.
* Participants with body surface area (BSA) of AD involvement, excluding the face and intertriginous areas, of 3% to 20% at screening and baseline.
* Participants who agree to discontinue all agents used to treat AD from screening through the final follow-up visit.

Exclusion Criteria:

* Participants with evidence of active acute or chronic infections.
* Use of topical treatments for AD (other than bland emollients) within 2 weeks of baseline.
* Systemic immunosuppressive or immunomodulating drugs (eg, oral or injectable corticosteroids, methotrexate, cyclosporine, mycophenolate mofetil, azathioprine) within 4 weeks or 5 half-lives of baseline (whichever is longer).
* Participants with other dermatologic disease besides AD whose presence or treatments could complicate the assessment of disease (eg, psoriasis).
* Participants with a history of other diseases besides dermatologic disorders (eg, other autoimmune diseases) taking treatments that could complicate assessments.
* Participants with cytopenias at screening, defined as:

  * Leukocytes \< 3.0 × 10\^9/L.
  * Neutrophils \< lower limit of normal.
  * Hemoglobin \< 10 g/dL.
  * Lymphocytes \< 0.8 × 10\^9/L
  * Platelets \< 100 × 10\^9/L.
* Participants with severely impaired liver function (Child-Pugh Class C) or end-stage renal disease (ESRD) on dialysis or at least 1 of the following:

  * Serum creatinine \> 1.5 mg/dL.
  * Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥ 1.5 × upper limit of normal.
* Participants taking potent systemic cytochrome P450 3A4 inhibitors or fluconazole within 2 weeks or 5 half-lives, whichever is longer, before the baseline visit (topical agents with limited systemic availability are permitted).
* Participants who have previously received Janus kinase (JAK) inhibitors, systemic or topical (e.g., ruxolitinib, tofacitinib, baricitinib, filgotinib, lestaurtinib, pacritinib).
