What this Trial Is About

Researchers are studying six immune-mediated inflammatory skin diseases: atopic dermatitis (AD), plaque psoriasis (PSO), hidradenitis suppurativa (HS), cutaneous T-cell lymphoma subtype mycosis fungoides (MF), chronic spontaneous urticaria (CSU), and cutaneous lupus erythematosus (CLE). This observational study aims to identify and compare biomarkers that distinguish responders from non-responders to treatments, understand differences between patients and healthy volunteers, and explore how biomarkers relate to disease subtypes and treatment outcomes. The study is part of the Next Generation ImmunoDermatology (NGID) initiative, which seeks to develop tools for personalized patient care. Participants will receive standard treatments for their specific skin condition according to national guidelines, including various immunosuppressants, biologics, and targeted therapies such as cyclosporine A, anti-IL4/13 antibodies, JAK1 inhibitors, anti-TNF agents, anti-IL17 therapies, BTK inhibitors, topical corticosteroids, and phototherapy. The study includes different treatment arms for each disease group, and patients will be monitored over one year with scheduled visits and assessments. Healthy volunteers will also be enrolled for baseline comparisons and followed for six weeks. Participants will attend clinic visits combined with their regular care appointments at baseline, month 3, month 6, and optionally month 12. They will complete online questionnaires multiple times during the study, and those with CSU will fill in daily symptom diaries (UAS7 and AAS7). Researchers will collect biological samples, perform imaging and molecular analyses, and evaluate disease severity using various clinical scoring tools. The main outcomes include measuring lipidomics, microbiome, serum and plasma biomarkers, and disease activity scores over 12 months to better understand disease progression and treatment responses.

Not Eligible

You will not qualify if you...

  • Other relevant skin infection or disease in treatment area
  • Treatment with any non-marketed drug within 4 weeks prior to baseline
  • Any condition interfering with study conduct or objectives
  • Recent treatments with preferred washout periods not met (topical, phototherapy, systemic, biologics, chemotherapy, radiotherapy, surgery)
  • CLE patients diagnosed with systemic lupus erythematosus
  • CSU patients treated with omalizumab within 8 weeks prior to baseline or with urticarial/angioedema symptoms such as urticarial vasculitis or mastocytosis

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Monitoring

Duration - 1 year

Participants are observed while starting and continuing their prescribed standard-of-care treatments for their skin condition. Various clinical, imaging, molecular, and patient-reported data are collected to profile disease and treatment response.

Visits at baseline, month 3, month 6, and month 12

Monitoring for Healthy Controls

Duration - 6 weeks

Healthy volunteers are observed for comparison over a short period without receiving treatment.

Visits at baseline and follow-up within 6 weeks
