Diagnosis of axial spondyloarthritis according to Ankylosing Spondylo Arthritis International Society (ASAS) axial spondyloarthritis criteria 3. Objective signs of inflammation (magnetic resonance imaging (MRI) or abnormal C-reactive protein) 4. Total back pain as measured by NRS ≥ 4 at baseline

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
1. The Percentage of Participants Who Achieved an Assessment of Spondylo Arthritis International Society (ASAS) 40 ResponseFrom Baseline to Week 16Assessment of Spondylo Arthritis International Society criteria (ASAS) consist of 6 domains (4 main and 2 additional assessment domains): 1. Patient's global assessment measured on a NRS; 2. Patient's assessment of back pain, measured on a NRS; 3. Function represented by Bath Ankylosing Spondylitis Functional Index (BASFI) average of 10 questions as measured by NRS; 4. Inflammation represented by mean duration and severity of morning stiffness, on the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) as measured by NRS; 5. Spinal mobility represented by the Bath Ankylosing Spondylitis Metrology Index (BASMI) lateral spinal flexion assessment; 6. C-reactive protein (acute phase reactant). ASAS40 response is defined as an improvement of ≥40% and ≥2 units on a scale of 10 in at least three of the four ASAS main domains and no worsening at all in the remaining domain. A higher score on the NRS signifies higher severity.

2. The Percentage of Participants Who Achieved an Assessment of Spondylo Arthritis International Society (ASAS) 20 ResponseFrom Baseline to the Week 16Assessment of Spondylo Arthritis International Society criteria (ASAS) consist of 6 domains (4 main and 2 additional assessment domains): 1. Patient's global assessment measured on a NRS; 2. Patient's assessment of back pain, measured on a NRS; 3.

Spinal mobility represented by the Bath Ankylosing Spondylitis Metrology Index (BASMI) lateral spinal flexion assessment; 6. C-reactive protein (acute phase reactant). ASAS 20 response is defined as an improvement of ≥20% and ≥1 unit on a scale of 10 in at least three of the four main domains and no worsening of ≥20% and ≥1 unit on a scale of 10 in the remaining domain. A higher score on the NRS signifies higher severity.
