About

This is a multi-center, longitudinal study which will characterize the gene expression profiles and transcriptomic endotypes that underlie mild and moderate-severe Atopic dermatitis (AD) and will determine changes in these expression patterns and endotypes in response to standard-of-care treatment. Participants will complete up to ten scheduled study visits with assessment of topical steroid response and dupilumab response (if uncontrolled with topical steroids). Skin samples will be collected at all study visits to determine the gene expression profiles and transcriptomic endotypes that underlie mild vs. moderate-severe AD disease. The investigators will also evaluate the lipidomic, metabolomic, proteomic, and microbiome profiles of AD skin endotypes associated with mild and moderate-severe AD disease. Non-AD participants will serve as a control population.

The primary objective of this study is to determine if the type 2-high non-lesional skin (skin tape) endotype is associated with current mild versus moderate-severe AD disease.

This includes hypersensitivity to local anesthetics (e.g., lidocaine or Novocain), bleeding disorders, treatment with anticoagulants or other conditions in adult participants that would make the biopsy procedure inadvisable

600 participants in 3 patient groups

Dupilumab-naïve atopic dermatitis participants
Experimental group
Description:
On Day 7, dupilumab-naïve AD participants will begin applying topical corticosteroids twice daily to their specified target area, as well as to active lesions on non-target skin. Dupilumab-naïve AD participants will return for a Steroid Assessment Visit at Day 35, when response to topical corticosteroids will be evaluated at the target site by TAA and targeted EASI scoring, and overall management of AD body-wide by topical steroid/moisturizer treatment will be evaluated by EASI score. Participants who are responsive to topical corticosteroids will continue to use them body-wide through Day 140. Participants who are non-responsive to topical corticosteroids at any time before Day 91 will begin use of dupilumab through their penultimate scheduled visit (Day 140-Day 196) and may continue use of topical corticosteroids outside of their specified target area as needed.
Treatment:
Drug: Vanicream- Dupilumab-naïve
Drug: Triamcinolone Acetonide
Biological: Dupilumab
Drug: Hydrocortisone
Experienced Dupilumab atopic dermatitis participants
Experimental group
Description:
AD participants already on dupilumab (for \>= 4 months prior to study entry (20 children, 40 adults)) at the start of the study will continue treatment with dupilumab as prescribed by their physician outside of the study. They may also continue treatment with other prescribed topical AD medications outside of the specified target skin area throughout the study; they may continue treatment with other prescribed topical AD medications within the specified target area from Day 7 through Day 140. Long-term dupilumab participants will apply Vanicream™ beginning at Day 0 through Day 7. Long-term dupilumab participants will return for assessment visits at Day 63 and 140. At Day 140, participants will resume application of Vanicream™ through the End of Study Assessment (Day 168).
Treatment:
Drug: Vanicream- Experienced Dupilumab
Non-atopic dermatitis participants
Active Comparator group
Description:
Approximately 150 will be non-AD controls (including approximately 50 children, 6-17 years of age, and 100 adults, = 18 years of age) Non-AD control participants will apply Vanicream™ beginning at Day 0 through Day 7. Non-AD control participants will return for assessment visits at Day 35, 91, and 140. At Day 140, participants will resume application of Vanicream™ through the End of Study Assessment (Day 168).
Treatment:
Drug: Vanicream- Active
