A Pilot Cohort Study of Risk Factors and Novel Methods of Skin Lesion Assessments in Adults With Atopic Dermatitis, Alopecia Areata, Psoriasis or Vitiligo

Conditions
Atopic Dermatitis
Psoriasis
Alopecia Areata
Vitiligo

Other: Observational
Registration Number
NCT06319781
Lead Sponsor
Blueskin AS
Brief Summary

The objective of the study is to explore various clinical and biochemical parameters and their potential associations with disease severity, activity, and prognosis in atopic dermatitis, psoriasis, alopecia areata, and vitiligo. Further, the study aims at validating remote assessments of skin lesions, using smartphone-acquired photos. The study will also assess the feasibility and compliance with weekly remote-assessments and patient-reported data collection over the full study period of one year. The study will observe patients through a period of one year and will provide detailed information concerning the type and dose of medication used, as well as data to evaluate the disease activity with high resolution during this period. The study will involve collection of serum samples for exploratory biomarkers, and punch biopsies. A total of approximately 370 patients, divided into the four disease areas of atopic dermatitis, alopecia areata, psoriasis, and vitiligo, will be enrolled in the study. Using a combination of self-reported and on-site assessments and procedures, the intent is to observe the natural history of patients with select dermatological conditions, investigate tissue characteristics associated with disease activity and symptoms, and evaluate the validity of remote assessment of lesions, and feasibility of weekly self-acquired smart-phone images of skin lesions for remote assessment.

Recruitment & Eligibility

Status
RECRUITING
Sex
All
Target Recruitment
370
Inclusion Criteria
  • Adult subjects >18 years of age at screening.
  • Previous diagnosis by a physician of atopic dermatitis, psoriasis, vitiligo, or alopecia areata.
  • Visible lesions and willingness to photograph weekly using their smartphone
  • Availability of a smartphone
Exclusion Criteria
  • Has any physical attributes or skin conditions that in the opinion of the investigator might interfere with the evaluation of lesions (i.e., pigmentation, tattoos, extensive scarring, excessive hair growth or acne)
  • Has other clinically relevant illness that could interfere with healing of lesions (e.g. keloid scaring)
  • Current or previous malignant disease, including malignant melanoma and basal cell carcinoma, within 5 years
  • Some patients may have more than one of the four conditions. This is not an exclusion criterion per se but must be recorded.

Primary Outcome Measures
NameTimeMethod
Clinical characteristics and disease activity.52 weeks

Association/correlations of clinical characteristics (age, sex, body-mass index, baseline disease activity score, disease duration etc.) with disease activity/flares

Compliance of remote tasks.52 weeks

Proportional compliance in % with required self-assessments and photo acquisitions during the study period

Disease activity and biomarkers.52 weeks

Associations of patient-reported treatment regimens and disease activity parameters, and relevant parameters derived from serum and skin biopsy biomarkers

Severity of the disease.52 weeks

Descriptive changes in relevant disease activity scores over the study period

Level of agreement between the in-person and remote scoring52 weeks

Level of agreement between the in-person and remote scoring, inter- and intrareliability, subsequent bias (average of differences) and precision estimates on the average difference between the scorings evaluated by the raters from remote and in-person, from the changes from baseline in relevant disease activity scores

Quality of life.52 weeks

Changes from baseline in quality of life as analyzed by the WHOQOL-BREF

Quality of smartphone collected photos.52 weeks

Proportion of acquired images which were deemed of adequate quality to facilitate remote assessment

Tissue profiling and disease activity.52 weeks

Changes in tissue profiling and associations with disease activity based on relevant analyses of skin punch biopsies and standard disease activity scoring scales as listed below
