Inclusion criteria
* The subjects understand and comply with the study requirements, voluntarily participate in the study and sign the informed consent form. * Ages at ≥18 and ≤ 65 years. * The diagnosis of atopic dermatitis will be confirmed according to the criteria of Hanifin and Rajka at the Screening Visit and Have a clinical diagnosis of atopic dermatitis for at least 6 months. * Have an Investigator's Global Assessment (IGA) score of 2, or3 at screening and at baseline. * Have atopic dermatitis on the head (excluding hair-bearing scalp), neck, trunk, or limbs, covering at least 2% of total BSA and up to and including 20% of total BSA at Screening and at baseline.
Exclusion criteria
* Subjects with other dermatologic disease besides AD whose presence or treatments could interfere the assessment of disease (eg, psoriasis). * In the opinion of the investigator, have any clinically significant laboratory abnormality that would affect the participant's participation in the study. * Use of topical treatments for AD within 2 weeks of baseline. * Vaccinated or exposed to a live or attenuated vaccine within the 12 weeks of baseline, or is expected to be vaccinated these vaccines during treatment. * A history of alcohol or substance abuse within 12 months prior to Screening that in the opinion of the investigator will preclude participation in the study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Achieving >=75% Improvement in Eczema Area and Severity Index Total Score (EASI-75) From Baseline at Weeks 8 | Baseline, Weeks 8 | EASI evaluates severity of participant's AD (excluded scalp, palms, soles) based on severity of AD clinical signs and % of body surface area (BSA) affected. Severity of clinical signs of AD (erythema, induration/papulation, excoriation and lichenification) scored separately for each of 4 body regions(head and neck, upper limbs, trunk \[including axillae and groin\] and lower limbs \[including buttocks\]) on4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % BSA with AD in each 4 body region: 0 (0%), 1 (\>0 to \<10%), 2 (10 to \<30%), 3 (30 to \<50%), 4 (50 to \<70%), 5 (70 to \<90%) and 6 (90 to 100%). Total EASI score =0.1\*Ah\*(Eh+Ih+Exh+Lh) + 0.2\*Au\*(Eu+Iu+ExU+Lu) + 0.3\*At\*(Et+It+Ext+Lt) + 0.4\*Al\*(El+Il+Exl+Ll); A = EASI area score; E = erythema; I = induration/papulation; Ex = excoriation; L = lichenification; h = head and neck; u = upper limbs; t = trunk; l = lower limbs. Total EASI score ranged from 0.0 to 72.0, higher scores = greater severity of AD. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Achieving Investigator's Global Assessment (IGA) Score Clear (0) or Almost Clear (1) and a Reduction From Baseline of Greater Than or Equal to ( >=2) Points at Week 8 | Baseline, Weeks 8 | IGA assesses severity of participant's AD on a 5 point scale. 0= clear, no inflammatory signs of AD; 1= almost clear, AD not fully cleared- light pink residual lesions (except post-inflammatory hyperpigmentation), just perceptible erythema, papulation/induration lichenification, excoriation, and no oozing/crusting; 2= mild AD with light red lesions, slight but definite erythema, papulation/induration, lichenification, excoriation and no oozing/crusting; 3= moderate AD with red lesions, moderate erythema, papulation/induration, lichenification, excoriation and slight oozing/crusting and 4= severe AD with deep dark red lesions, severe erythema, papulation/induration, lichenification, excoriation and moderate to severe oozing/crusting. Higher scores indicating more severity of AD. Assessment excluded soles, palms and scalp. |
