A Multicenter Registry of Adalimumab in Chinese Adult Patients With Active Ankylosing Spondylitis

Study Overview
=================
Brief Summary
-----------------
A multicenter registry to explore the clinical outcome of Chinese adult patients with active Ankylosing Spondylitis *AS* treated with adalimumab,prescribed according to the local label,in the real world practice

Detailed Description
-----------------
This registry will be conducted in a non-interventional setting for AS patients using adalimumab in China.The primary objective is to evaluate the effectiveness and safety of adalimumab in Chinese AS patients in real world clinical practice.The secondary objective is to 1)compare the clinical outcome in patients with or without good persistence with adalimumab;2)investigate the predicting factors of a good clinical response after discontinuation of adalimumab.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Adalimumab<br>Chinese adult patients with a diagnosis of AS who meet the requirements per the local label for treatment with adalimumab. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effectiveness of adalimumab, measured as percentage of patients achieving Bath Ankylosing Spondylitis Disease Activity Index *BASDAI* 50 at week12 with adalimumab treatment. |  | week12 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effectiveness of adalimumab measured as change in BASDAI,Ankylosing Spondylitis Disease Activity Scores *ASDAS*,Visual Analogue Scale *VAS* in pain,Patient Global Assessment *PtGA* with adalimumab treatment. |  | week 12 | 
| Proportion of patients who achieve each of the ASDAS disease state categories(inactive,mild,moderate,high) with adalimumab treatment. |  | week 12 | 
| Improvement of extra-articular manifestation with adalimumab treatment compared to baseline: uveitis flare rates, patient proportion with VAS scale at 1 in IBD PtGA, patient proportion with skin lesion clear or almost clear in psoriasis PGA. | Physician Global Assessment*PGA*. Inflammatory Bowel Disease *IBD* | week 12 | 
| BASDAI50 response rate at week 26 and week52 in patients still on adalimumab compared to patients who discontinued adalimumab early. |  | week26 and 52 | 
| Change in BASDAI, ASDAS, and VAS in pain and PtGA in patients still on adalimumab compared to patients who discontinued adalimumab early. |  | week 26 and 52 | 
| Factors influencing the clinical response evaluated by the relapse rate(defined as BASDAI≥4) after discontinuation of adalimumab in patients who achieved BASDAI <4 and do not restart biologics in the follow-up |  | week 52 |
