Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Alopecia Areata (AA) symptoms affecting quality of life and daily functioning, assessed by the Alopecia Areata Symptom Impact Scale (AASIS) AA only | Up to Day 1 | AASIS- is a scale assessing the severity of AA-related symptoms on daily functioning. Each item scored on a 0-10 Likert scale, where 0 = not present and 10 = as bad as you can imagine Higher total score = greater impact |
| Measuring scalp hair loss, assessed by the Severity of Alopecia Tool (SALT) score. AA only | Up to Day 1 | SALT is a Tool developed to quantify AA-related hair loss Total score of 0-100, with 0 = no hair loss, and 100 = complete hair loss |
| Measuring facial skin depigmentation, assessed by the Facial Vitiligo Area Scoring Index (F-VASI) Vitiligo Only | Up to Day 1 | F-VASI is a quantitative scoring tool used to evaluate the extent and severity of facial vitiligo calculated by multiplying the degree of skin depigmentation of the face |
| Vitiligo Quality of Life (QOL), assessed by Vitiligo Quality of Life Score (VitiQoL) Vitiligo Only | Up to Day 1 | VitiQoL is a 16-item instrument assessing impact of vitiligo on QoL. 15 items are scored on a 7-point Likert scale, ranging from "not at all" to "all the time". An additional item (not contributing to total score) assesses current severity of condition on a 7-point scale ranging from "no skin involvement" to "most severe case" |
| Hidradenitis Suppurativa (HS) Quality of Life (QOL), assessed by Dermatology Life Quality Index (DLQI)/Children's Dermatology Life Quality Index (CDLQI) HS only | Up to Day 1 | CDLQI is a10-question index measuring health-related quality of life (HRQoL) over the last 7 days for patients suffering from a skin disease. The DLQI is used in participants aged 16 and over and the CDLQI has been validated from the ages of 4 to 16 years. Each item scored on a 4-point Likert scale, where 0 = not at all/not relevant/question unanswered and 3 = very much. Maximum total score = 30 (highest impact on QoL). |
| Measuring disease severity, assessed by the International Hidradenitis Suppurativa Severity Scoring System (IHS4) HS only | Up to Day 1 | The IHS4 score is calculated as follows: number of nodules (multiplied by 1) + number of abscesses (multiplied by 2) + number of draining tunnels (multiplied by 4). A total score of 3 or less signifies mild, 4 to 10 signifies moderate, and 11 or higher signifies severe disease. |
