Long Term Observational Study to Collect in a Real-world populatIon Data on the Treatment Pattern of secukinumAb in Adult Patients With Moderate to Severe Hidradenitis Suppurativa.

Study Overview
=================
Brief Summary
-----------------
The purpose of this observational, prospective, non-interventional, multicenter, open-label, single arm study in Hidradenitis suppurativa (HS) is to assess the treatment pattern of secukinumab in a flexible dosing regimen and decision influencing factors for flexible dosing in a real-world population over 2 years.

Detailed Description
-----------------
The study will collect data from patients during routine secukinumab treatment and will be representative of the real-world patient population eligible for secukinumab treatment in Germany. In order to attain widespread representation of health care practices related to the use of secukinumab in the approved indication of moderate to severe HS, a broad spectrum of dermatology practices and clinics who are treating patients with HS across Germany will be included.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of patients receiving up-titration | Proportion of patients receiving up-titration (q4w-to-q2w) | Up to 24 months | 
| Proportion of patients receiving down-titration | Proportion of patients receiving down-titration (q2w-to-q4w) | Up to 24 months | 
| Time to up-titration and down-titration | Time to up-titration and down-titration | Up to 2 years | 
| Duration of q4w treatment with secukinumab after dose reduction | Duration of q4w treatment with secukinumab after dose reduction | Up to 2 years | 
| Proportion of patients who receive more than one up-and/or down titration | Proportion of patients who receive more than one up-and/or down titration | Up to 24 months | 
| Proportion of patients receiving HS-specific concomitant treatments in combination with secukinumab | Proportion of patients receiving HS-specific concomitant treatments in combination with secukinumab | Up to 2 years | 
| Number and type of surgical interventions | Number and type of surgical interventions minor and major surgical excision; inpatient, outpatient | Up to 2 years | 
| Proportion of patients achieving 55% reduction in IHS4 (IHS4-55) | The IHS4 is an exclusively physician-based, clinical scoring system for dynamic assessment of HS severity. HS severity is calculated based on the number of lesions multiplied by their respective score: the IHS4 score (points) = (number of nodules multiplied by 1) + (number of abscesses multiplied by 2) + [number of draining tunnels (fistulae/sinuses) multiplied by 4]. A score of 3 or less signifies mild HS, a score of 4-10 signifies moderate HS and a score of 11 or higher signifies severe HS | Up to 24 months | 
| mean change of International Hidradenitis Suppurativa Severity Score System (IHS4) | The IHS4 is an exclusively physician-based, clinical scoring system for dynamic assessment of HS severity. HS severity is calculated based on the number of lesions multiplied by their respective score: the IHS4 score (points) = (number of nodules multiplied by 1) + (number of abscesses multiplied by 2) + [number of draining tunnels (fistulae/sinuses) multiplied by 4]. A score of 3 or less signifies mild HS, a score of 4-10 signifies moderate HS and a score of 11 or higher signifies severe HS | Up to 24 months | 
| Proportion of patients achieving a 5-point reduction of their Dermatology Life Quality Index (DLQI) questionnaire | The DLQI is a 10-item general dermatology disability index designed to assess health-related quality of life (HRQoL) in adult subjects with skin diseases such as eczema, psoriasis, acne, and viral warts. The measure is self-administered and includes domains of daily activities, leisure, personal relationships, symptoms and feelings, treatment, and work/school. Each item has four response categories ranging from 0 (not at all) to 3 (very much). Not relevant is also a valid response and is scored as 0. The DLQI total score is a sum of the 10 questions. Scores range from 0 to 30, with higher scores indicating greater HRQoL impairment. | Up to 24 months | 
| Mean reduction of Abscesses and inflammatory nodules (AN) count | Mean reduction of Abscesses and inflammatory nodules (AN) count | Up to 24 months | 
| Proportion of patients achieving a 30% reduction of pain Numerical Rating scale 30 (NRS30) | The NRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of their pain ranging from 0 (no skin pain) to 10 (skin pain as bad as you can imagine). To assess this, the patient should concentrate on the pain that his/her skin lesions generate. The Patient's Global Assessment of Skin Pain - NRS will be completed by the subject electronically via a web-based application or in paper form. | Up to 24 months |
