Accepts healthy volunteers: yes
Observational model: COHORT
Time perspective: CROSS_SECTIONAL
Sampling method: PROBABILITY_SAMPLE
Study population: Participants are enrolled at selected investigational sites in a standard clinical practice setting

Brief summary: The main objectives of the study are: To determine if RNA recovery from tape harvesting allows for the identification of a disease gene signature (e.g., interferon \[IFN\] signature for lupus) or other biomarkers that may differentiate affected from normal or unaffected skin; To determine if the lupus gene signature is differentially expressed in the epidermis from active discoid lupus erythematosus (DLE) or subacute cutaneous lupus erythematosus (SCLE) lesions when compared with unaffected skin from the same participants and from the skin of healthy volunteers (HVs); To determine if the atopic dermatitis (AD) gene signature is differentially expressed in the epidermis from active AD lesions when compared with unaffected skin from the same participants and from the skin of HVs; and To correlate the levels of transcripts of targeted genes in the skin by tape harvesting with those obtained from the blood.

Detailed description: No study drug is administered as part of this study. All participants except healthy volunteers will be treated according to standard clinical practice.

Eligibility criteria: Key Inclusion Criteria:

* Healthy volunteers must be in good overall health as determined by the Investigator, based on medical history, physical examination (per standard dermatology practice), and vital signs.
* Subjects with lupus must present with active DLE or SCLE skin disease (with or without systemic manifestations of SLE, as defined by ≥4 out of 11 classification criteria for SLE).
* Subjects with AD must have been diagnosed by the Eichenfield revised criteria of Hanifin and Rajka, disease duration for at least 2 years before Screening and disease activity defined as Investigator's Global Assessment (IGA) score ≥3 at screening

Key Exclusion Criteria:

* History of severe allergic or anaphylactic reactions or history of allergic reactions likely to be exacerbated by tape harvesting (e.g., allergy to adhesives).
* Other unspecified reasons that, in the opinion of the Investigator, make the subject unsuitable for enrollment.

Key Exclusion Criteria for Healthy Volunteers

* History of any clinically significant medical condition, as determined by the Investigator, that may impact study analyses

Key Exclusion Criteria for Subjects with Discoid or Subacute Cutaneous Lupus:

* Evidence of skin conditions other than DLE or SCLE at the Day 1 Visit that, in the opinion of the Investigator, would interfere with the study execution or analysis.
* History of malignancy in the last 5 years (nonmelanoma skin cancer that is considered cured by the Investigator will not be exclusionary).

Key Exclusion Criteria for Subjects With Atopic Dermatitis:

* History of any clinically significant medical condition, other than AD, as determined by the Investigator, that may impact study analyses, including, but not limited to: History of human immunodeficiency virus; History of hepatitis C virus or hepatitis B virus infection; Symptoms of bacterial or viral infection (including skin infection) within 14 days prior to the Day 1 Visit; History of malignancy in the last 5 years (nonmelanoma skin cancer that is considered cured by the Investigator will not be exclusionary).
* Evidence of skin conditions other than AD at the Day 1 Visit that, in the opinion of the Investigator, would interfere with the study execution or analysis.

NOTE: Other protocol-defined inclusion/exclusion criteria may apply.
