A Prospective Multicenter Study for the Assessment of Treatment Patterns, Effectiveness and Safety of Secukinumab in Adult Patients With Moderate to Severe Plaque Psoriasis in a Real-world Setting in China

Study Overview
=================
Brief Summary
-----------------
This non-interventional, prospective, multi-center study aims to provide short- and long- term treatment patterns, effectiveness, and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis (with and without PsA) initiating treatment of secukinumab.

Detailed Description
-----------------
All patients will be followed up for 52 weeks no matter they adhere to secukinumab or they have shifted to other treatment plans. Data will be collected in conjunction with routine care visits, most likely happen at week 0, 4, 12, 16, 24, 36, 52. No extra study visits, examinations, laboratory tests or procedures will be mandated. If visits happen at other time points (not within the window period), then they will be counted as unscheduled visits.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of patients achieving a 90% reduction in the Psoriasis Area and Severity Index (PASI) score | The PASI is used for assessing and grading the severity of psoriatic lesions and their response to therapy. PASI scores can range from a lower value of 0, corresponding to no signs of psoriasis, up to a theoretic maximum of 72.0. | week 24 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of patients experiencing a 75% reduction of PASI (PASI75) | The PASI is used for assessing and grading the severity of psoriatic lesions and their response to therapy. PASI scores can range from a lower value of 0, corresponding to no signs of psoriasis, up to a theoretic maximum of 72.0. | week 4, week12, week 16, week 24, week 36, week 52 | 
| Percentage of patients experiencing a 90% reduction of PASI (PASI90) | The PASI is used for assessing and grading the severity of psoriatic lesions and their response to therapy. PASI scores can range from a lower value of 0, corresponding to no signs of psoriasis, up to a theoretic maximum of 72.0. | week 4, week12, week 16, week 36, week 52 | 
| Percentage of patients experiencing a 100% reduction of PASI (PASI100) | The PASI is used for assessing and grading the severity of psoriatic lesions and their response to therapy. PASI scores can range from a lower value of 0, corresponding to no signs of psoriasis, up to a theoretic maximum of 72.0. | week 4, week12, week 16, week 24, week 36, week 52 | 
| Percentage of patients with absolute PASI change ≤1, ≤2, ≤3,and ≤5 | The PASI is used for assessing and grading the severity of psoriatic lesions and their response to therapy. PASI scores can range from a lower value of 0, corresponding to no signs of psoriasis, up to a theoretic maximum of 72.0 | week 4, week12, week 16, week 24, week 36, week 52 | 
| Percentage of patients with Investigator Global Assessment Mod 2011 (IGA mod 2011) 0 or 1 | The IGA mod 2011 rating scale for overall psoriatic disease can range from 0 to 4 (0: Clear, 1: almost clear, 2: mild, 3: moderate, 4: severe) | week 4, week12, week 16, week 24, week 36, week 52 | 
| Mean change of Investigator Global Assessment Mod 2011(IGA mod 2011) | The IGA mod 2011 rating scale for overall psoriatic disease can range from 0 to 4 (0: Clear, 1: almost clear, 2: mild, 3: moderate, 4: severe) | week 4, week12, week 16, week 24, week 36, week 52 | 
| Percentage of patients achieved (Body Surface Area) BSA≤1% | The total BSA affected by plaque-type psoriasis will be estimated from the percentages of areas affected, including head, trunk, upper limbs and lower limbs. The following calculations will be done: each reported percentage will be multiplied by its respective body region corresponding factor (head = 0.1, trunk = 0.3, upper limbs = 0.2, lower limbs = 0.4). The resulting four percentages will be added up to estimate the total BSA affected by psoriasis. | week 4, week12, week 16, week 24, week 36, week 52 | 
| Mean change in Dermatology life quality index (DLQI) | DLQI is a 10-item general dermatology disability index designed to assess HRQoL in adult patients 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 4 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 and higher scores indicate greater HRQoL impairment. Additionally, each subscale of the DLQI may be analyzed separately. | Baseline,week 4, week12, week 16, week 24, week 36, week 52 | 
| Percentage of patients achieving DLQI 0 or 1 response | DLQI is a 10-item general dermatology disability index designed to assess HRQoL in adult patients with skin diseases such as eczema, psoriasis, acne and viral warts.
