An Observational, Prospective Cohort Study to Evaluate Safety and Efficacy of RemsimaTM in Patients with Ankylosing Spondylitis
This is a longitudinal, observational, prospective cohort study to assess the safety and efficacy of RemsimaTM in patients with AS in comparison with patients receiving other TNF blockers. For the RemsimaTM cohort data will be collected for patients who commence treatment with RemsimaTM in accordance with the product label at the time of enrolment. Patients who have been treated with Remicade® prior to enrolment, their dosing schedule will be continued appropriately. This observational study allows drug switching between anti-TNF drugs. If switched to RemsimaTM, data will be collected until the end of study for each patient. If switched to other anti-TNF drugs (infliximab (Remicade®), etanercept, adalimumab and etc.), data will be collected until 1 year from the day of switch or until the end of study for each patient, whichever reaches earlier. For switched patients, their assessment schedule will be re-started from the day of switch. Patients will undergo safety and efficacy assessments in accordance with routine medical practice. The decision to treat with RemsimaTM will be independent of the decision to enroll the patient in this registry.

Time frame: Duration of study participation (up to 5 years)
The Number and Percentage of Patients Achieving BASDAI 50
Efficacy was assessed by the evaluation of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). The BASDAI questionnaire consists of 6 component questions about the disease activity. For each question the possible answer from the patient is a whole number from 0 to 10 inclusive where 0 = None and 10 = Very severe. The BASDAI score is generated from the set of 6 questions and calculated using the following formula BASDAI = \[Q1+Q2+Q3+Q4+(\[Q5+Q6\]/2)\]/5. The number and percentage of patients achieving BASDAI 50 will be displayed. BASDAI 50 is defined as a 50% decrease of the baseline BASDAI score. Percentages will be calculated using the number of patients who perform the assessment at each time point.
Time frame: Month 6 ~ Month 48 (every 6 months ± 6 weeks)
Descriptive Statistics for BASFI
The Bath Ankylosing Spondylitis Functional Index (BASFI) questionnaire consists of 10 component questions measuring functionality. Each item was given a rating by the patient which is a whole number from 0 to 10 inclusive where 0 = Easy and 10 = Impossible. The BASFI score is generated from the mean of the scores for the 10 items. The lowest score is 0 and the highest score is 10, with higher scores indicating a higher degree of functional limitation in patients.

Descriptive Statistics of Physician Global Assessment Score
Physician and Patient Global Assessment of disease status was measured by Visual Analogue Scale (VAS) (0-100 mm) for EU patients and Numerical Rating Scale (NRS) (0-10) for Korea patients where higher scores indicated poorer status. Descriptive statistics for actual value of Global Assessment Score were summarized by analysis group and every six months including Day 0. For the summary table, each score of Korea patients in NRS was transformed by multiplying 10. Scores are from 0 to 100, with higher scores indicating more disease activity.
Time frame: Day 0 ~ Month 48 (every 6 months ±6 weeks)
Descriptive Statistics of Patient Global Assessment Score
Physician and Patient Global Assessment of disease status was measured by Visual Analogue Scale (VAS) (0-100 mm) for EU patients and Numerical Rating Scale (NRS) (0-10) for Korea patients where higher scores indicated poorer status. Descriptive statistics for actual value of Global Assessment Score were summarized by analysis group and every six months including Day 0. For the summary table, each score of Korea patients in NRS was transformed by multiplying 10. Scores are from 0 to 100, with higher scores indicating more disease activity.
Time frame: Day 0 ~ Month 48 (every 6 months ±6 weeks)
Descriptive Statistics of Spinal Pain Score
Patient Assessment of Spinal Pain will be measured by VAS (0-100 mm) for EU patients and NRS (0-10) for Korea patients where higher scores indicates more severe pain. Descriptive statistics for actual value of Spinal Pain Score will be summarized by analysis group and every six months including Day 0. For the summary table, each score of Korea patients in NRS will be transformed by multiplying 10. Scores are from 0 to 100, with higher scores indicating more pain as assessed by the patient.
Time frame: Day 0 ~ Month 48 (every 6 months ±6 weeks)
