Brief Summary

Prospective longitudinal study to characterize Choronic Hand Eczema (CHE) subtypes and Atopic Dermatitis (AD) with noninvasive molecular and imaging techniques, and assess changes through time and its association with quality of life.

Eligibility Criteria

Inclusion Criteria: All subjects: 1. Male or female subjects aged 18 to 65 years, inclusive, at the time of consent. 2. Subject is willing to participate and is capable of giving informed consent. Note: Consent must be obtained prior to any study-related procedures. 3. Subject must be willing to comply with all study procedures and must be available for the duration of the study. CHE subjects only: 4. Subject has at least a 6-month history of CHE before Screening (information obtained from medical chart or subject's physician, or directly from the subject). 5. Subject has moderate to severe CHE as defined by an IGA score of ≥3 at Screening and Day 1. 6. Subject has CHE covering ≥0.25% of BSA on palmar surface of hands at Screening and Day 1. 7. Subjects has CHE that can be categorized in one of the following CHE subtypes at Day 1: * Atopic hand eczema (without wet-work or excessive contact with irritants) * Irritant contact hand eczema without atopic disease * Hyperkeratotic hand eczema without atopic disease * Vesicular hand dermatitis without atopic disease * Allergic contact hand eczema without atopic disease * Idiopathic hand eczema without wet-work, excessive contact with irritants, atopic disease, hyperkeratotic morphology, allergic contact hand eczema and vesicular hand eczema. Subjects with only AD: 8. Subject has clinically confirmed diagnosis of active atopic dermatitis, according to Hanifin and Rajka criteria. 9. Subject has at least a 6-month history of AD and had no significant flares in AD for at least 4 weeks before Screening (information obtained from medical chart or subject's physician, or directly from the subject). 10. Subject has moderate to severe AD as defined by a vIGA-AD score of ≥3 at Screening and Day 1. 11. Subject has AD covering ≥0.5% of BSA at Screening and Day 1. 12. Subject has an AD lesion covering ≥0.25% of BSA on the forearm at Screening and Day 1.Healthy Volunteers only: 13. Subject is in good general health, according to the investigator's judgment based on medical history and physical examination. Exclusion Criteria: All subjects: 1. Subject has a history of skin disease or presence of skin condition that, in the opinion of the investigator, would interfere with the study assessments. 2.

Subject has used doxepin within 1 week prior to Day 1. 12. Subject has used hydroxyzine or diphenhydramine within 1 week prior to Day 1. 13. Subject has used any topical medicated treatment that could affect CHE within 1 week prior to Day 1, including, but not limited to, topical corticosteroids, topical retinoids, crisaborole, calcineurin inhibitors, tars, antimicrobials, medical devices, and bleach baths. 14. Subject has used alitretinoin, isotretinoin, acitretin or other systemic retinoids within 4 weeks before Day 1, or has not completely recovered from its side effects. 15.
