About this study

Official title: ADBest-TREAT: A Registry for Patients With Atopic Dermatitis Receiving Systemic, Local, or UV Therapy

Atopic dermatitis is a chronic inflammatory skin disease associated with intense pruritus, recurrent eczematous lesions, sleep disturbance, and reduced quality of life. The disease may be influenced by genetic factors, environmental triggers, epidermal barrier dysfunction, and immune dysregulation. Patients may experience flares triggered by allergens, infections, dry skin, stress, irritants, or other environmental factors. Atopic dermatitis can also be associated with secondary bacterial or viral skin infections and a substantial burden on daily activities, work productivity, sleep, and psychosocial well-being.TREAT is the German national treatment registry for patients with atopic dermatitis. The registry collects real-world data from routine dermatological care to assess disease course, treatment patterns, disease burden, patient-relevant treatment benefits, and quality of life. Data are collected electronically using physician-completed eCRFs and patient-completed questionnaires at inclusion and follow-up visits. The registry aims to improve understanding of atopic dermatitis real-world care and outcomes in daily clinical practice.

Read the detailed description

ADBest-TREAT uses a fully electronic data collection system. Study data are collected through web-based electronic case report forms (eCRFs), which can be completed via a web browser on a computer or tablet. After a patient is included in the registry, the patient is registered in the eCRF system using a pseudonymized identification number, and a visit schedule is generated automatically.

The registry uses separate electronic forms for physicians and patients. Physicians complete online doctor eCRFs at the inclusion visit and follow-up visits. These physician-completed eCRFs document eligibility criteria, clinical diagnosis, disease course, clinical phenotype, affected body sites, disease severity scores including PGA/IGA and EASI (Eczema Area and Severity Index), comorbidities, allergic sensitization, previous and current therapies, treatment changes, safety and tolerability information, and planned follow-up.

Patients complete separate online patient questionnaires and/or patient app entries during routine visits at defined intervals. These patient-completed questionnaires collect patient-reported information, including demographic data, lifestyle factors, disease history, family history of atopic diseases, symptoms, flares, physician visits, work impairment, affected skin areas, itch, sleep impairment, pain, dermatology-related quality of life using the DLQI (Dermatology Life Quality Index), treatment satisfaction, treatment benefit, and the personal importance of treatment goals.

Physician-reported and patient-reported data are therefore collected separately but within the same electronic registry system, allowing clinical information from physicians and patient-reported outcomes from patients to be analyzed together.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Eczema Area and Severity Index(EASI) score

    Atopic dermatititis severity will be assessed by the physician using the Eczema Area and Severity Index (EASI).The score ranges from 0 to 72 ,with higher scores indicating greater disease severity.

    Measured: At registry inclusion (week 0),at weeks 16,28, and 52 ,and every 24 weeks thereafter through 60 months.

  2. Dermatology Life Quality Index (DLQI) score

    Quality of life will be assessed using the 10 -item Dermatology Life Quality Index.(DLQ),referring to the previous week.Total score ranges from 0 to 30 ;Higher scores indicates greater impairement of quality of life.

    Measured: At registry inclusion (week 0),at weeks 16,28, and 52 ,and every 24 weeks thereafter through 60 months;an additional visit during weeks 0-4 may occur optionally.

Secondary outcomes (9)
  1. Physician-reported clinical phenotype and affected body sites

    Clinical phenotype and affected body sites are documented by the physician using the online eCRF, including disease course, clinical subtype, and current eczematous involvement of predefined anatomical areas.

    Measured: At inclusion;phenotype and disease course updated as needed.Body -site involvement assessed at registry inclusion (week 0) at weeks 16,28,and 52 ,then every 24 weeks through months 60.

  2. Atopic Dermatitis-related Pain Intensity

    Pain intensity during 24 hours,rated by the patient on a 0-10 scale (0=no pain;10=worst imaginable pain).Higher scores indicate more pain.

    Measured: At registry inclusion(week 0),at weeks 16,28, and 52 ,and every 24 weeks thereafter through month 60.

  3. Physician-reported Adverse Events During Routine Care

    Adverse events are documented by treating physicians in the online electronic case report form (eCRF) during routine care. Results will be reported as the number and percentage of participants with at least one documented adverse event;event type and severity will be reported when available.

    Measured: At weeks 16,28, and 52, then every 24 weeks through month 60,and at unscheduled visits when applicable.

  4. Physician/Investigator Global Assessment( PGA/IGA).

    Atopic dermatitis severity is assessed by the physician using the Physician /Investigator Global Assessment (PGA/IGA).Scores range from 0 to 5 :0=clear,1=almost clear,2=mild,3=moderate,4=severe, and 5 =very severe.Higher scores indicate greater disease severity.

    Measured: At registry inclusion(week 0),at weeks 16,28, and 52 ,and every 24 weeks thereafter through month 60.

  5. Sleep impairment

    Atopic dermatitis-related sleep impairment during the previous night,rated by the patient on a 0-10 scale (0=no impairment;10=extreme impairment).Higher scores indicate greater impairment.

    Measured: At registry inclusion(week 0),at weeks 16,28, and 52 ,and every 24 weeks thereafter through month 60.

  6. Patient-assessed atopic dermatitis severity

    Current disease severity reported by the patient as clear,almost clear,mild,moderate ,severe,or very severe.

    Measured: At registry inclusion(week 0),at weeks 16,28, and 52 ,and every 24 weeks thereafter through month 60.

  7. Patient-reported disease control

    Number of weeks during the previous 12 weeks in which atopic dermatitits was well controlled,reported by the patient(0-12 weeks).

    Measured: At weeks 16,28, and 52 ,and every 24 weeks thereafter through month 60.

  8. Patient satisfaction with treatment

    Patient satisfaction with medical care and atopic dermatitis treatment during the previous 3 months,rated on a 0-10 scale(0=very dissatisfied,10=very satisfied).

    Measured: At weeks 16,28, and 52 ,and every 24 weeks thereafter through month 60.

  9. Atopic Dermatitis-related Itch Intensity

    Patient-reported worst itch intensity due to atopic dermatitis during the previous 24 hours,measured on an 11-point numeric rating scale from 0(no itch) to 10 (worst imaginable itch).Higher scores indicate greater itch intensity.

    Measured: At registry inclusion(week 0),at weeks 16,28, and 52 ,and every 24 weeks thereafter through month 60.
