Outcome Measures
  • Primary Outcome Measures: 1. Assessment of SpondyloArthritis International Society 40% response criteria (ASAS40) response at Week 16 [ Time Frame: Week 16 ]
    ASAS40 will be calculated relative to Baseline. The Assessment of SpondyloArthritis International Society (ASAS) criteria for 40% improvement are defined as relative improvements of at least 40%, and absolute improvement of at least 2 units on a 0 to 10 Numeric Rating Scale (NRS) in at least 3 of the 4 domains and no worsening at all in the remaining domain. The domains are: Patient's Global Assessment of Disease Activity (PGADA) Pain assessment (the total spinal pain, NRS score) Function (represented by Bath Ankylosing Spondylitis Functional Index (BASFI)) Inflammation (the mean of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI))
  • Secondary Outcome Measures: 1. Assessment of SpondyloArthritis International Society 40% response criteria (ASAS40) response in TNFα inhibitor-naïve subjects at Week 16 [ Time Frame: Week 16 ]
    ASAS40 will be calculated relative to Baseline. The Assessment of SpondyloArthritis International Society (ASAS) criteria for 40% improvement are defined as relative improvements of at least 40%, and absolute improvement of at least 2 units on a 0 to 10 Numeric Rating Scale (NRS) in at least 3 of the 4 domains and no worsening at all in the remaining domain. The domains are: Patient's Global Assessment of Disease Activity (PGADA) Pain assessment (the total spinal pain, NRS score) Function (represented by Bath Ankylosing Spondylitis Functional Index (BASFI)) Inflammation (the mean of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI))
  • 2. Change from Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at Week 16 [ Time Frame: Baseline, Week 16 ]
    The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a validated self-reported instrument, which consists of six 10 unit horizontal Numeric Rating Scales (NRS) to measure the disease activity of ankylosing spondylitis (AS) from the subject's perspective. It measures the severity of fatigue, spinal and peripheral joint pain and swelling, enthesitis, and morning stiffness (both severity and duration) over the last week. The final BASDAI scores ranges from 0 to 10, with lower scores indicating lower disease activity.
  • 3. Assessment of SpondyloArthritis International Society 20% response criteria (ASAS20) response at Week 16 [ Time Frame: Week 16 ]
    ASAS20 will be calculated relative to Baseline. The Assessment of SpondyloArthritis International Society (ASAS) criteria for 20% improvement are defined as relative improvements of at least 20%, and absolute improvement of at least 1 unit on a 0 to 10 Numeric Rating Scale (NRS) in at least 3 of the 4 following domains and absence of deterioration in the potential remaining domain. The domains are: Patient's Global Assessment of Disease Activity (PGADA) Pain assessment (the total spinal pain, NRS score) Function (represented by Bath Ankylosing Spondylitis Functional Index (BASFI)) Inflammation (the mean of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI))
  • 4. Assessment of SpondyloArthritis International Society (ASAS) partial remission (PR) at Week 16 [ Time Frame: Week 16 ]
    The Assessment of SpondyloArthritis International Society (ASAS) partial remission (PR) is defined as a score of <=2 units on a 0 to 10 unit scale in all 4 domains listed for ASAS20.
  • 5. Ankylosing Spondylitis Disease Activity Score major improvement (ASDAS-MI) at Week 16 [ Time Frame: Week 16 ]
    Ankylosing Spondylitis Disease Activity Score major improvement (ASDAS-MI) is achieved when there is a reduction (improvement) >= 2.0 in the Ankylosing Spondylitis Disease Activity Score (ASDAS) relative to Baseline. ASDAS is calculated as the sum of the following components: 0.121 × Total back pain (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Q2 result) 0.058 × Duration of morning stiffness (BASDAI Q6 result) 0.110 × Patient's Global Assessment of Disease Activity (PGADA) 0.073 × Peripheral pain/swelling (BASDAI Q3 result) 0.579 × (natural logarithm of the C-reactive protein (CRP) [mg/L] + 1) Total back pain, PGADA, duration of morning stiffness, peripheral pain/swelling and fatigue are all assessed on a numerical scale (0 to 10 units). High ASDAS scores mean worse disease. If a subjects achieves the ASDAS-MI it indicates a major improvement of their disease.
  • 6. Assessment of SpondyloArthritis International Society (ASAS) 5/6 response at Week 16 [ Time Frame: Week 16 ]
    The Assessment of SpondyloArthritis International Society (ASAS) 5/6 response is defined as achieving at least 20% improvement in 5 of 6 domains, including the 4 domains defined for ASAS20 as well as spinal mobility (lateral spinal flexion) and C-reactive Protein (CRP).
  • 7. Change from Baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) at Week 16 [ Time Frame: Baseline, Week 16 ]
    The Bath Ankylosing Spondylitis Functional Index (BASFI) assesses physical function in comprising 10 items relating to activities during the past week. Each item ranges from 0 ('Easy') to 10 ('Impossible'). The BASFI is the mean of the 10 scores such that the total score ranges from 0 to 10, with lower scores indicating better physical function. A negative value in BASFI change from Baseline indicates an improvement from Baseline. The higher the negative value the better the improvement.
  • 8. Change from Baseline in nocturnal spinal pain Numeric Rating Scale (NRS) at Week 16 [ Time Frame: Baseline, Week 16 ]
    Change from baseline in the nocturnal spinal pain NRS at Week 16. Nocturnal spinal pain experienced by ankylosing spondylitis (AS) subjects is measured by one question: pain in the spine at night due to AS?. When responding, the subject is to consider the average amount of pain in the preceding week. It is assessed on a numerical scale (0 to 10 units). A lower score indicates less pain and an improvement of the outcome.
  • 9. Change from Baseline in Ankylosing Spondylitis Quality of Life (ASQoL) at Week 16 [ Time Frame: Baseline, Week 16 ]
    The Ankylosing Spondylitis Quality of Life (ASQoL), a validated disease-specific 18-item questionnaire, has been developed specifically for measuring health-related quality of life (HRQoL) in subjects with ankylosing spondylitis (AS) and has shown to be responsive in axial spondyloarthritis (axSpA). The ASQoL score ranges from 0 to 18 with a higher score indicating worse HRQoL.
  • 10. Change from Baseline in the Short Form 36-Item Health Survey (SF-36) physical component summary (PCS) at Week 16 [ Time Frame: Baseline, Week 16 ]
    There are 8 SF-36 domain scores. In addition to domain scores, the PCS scores are calculated from the 8 domains. Each of the 8 domain scores and the component summary scores ranging from 0 to 100, with higher scores indicating better health status. A larger positive value in change from Baseline indicates an improvement.
  • 11. Change from Baseline in Bath Ankylosing Spondylitis Disease Metrology Index (BASMI) at Week 16 [ Time Frame: Baseline, Week 16 ]
    The Bath Ankylosing Spondylitis Disease Metrology Index (BASMI) characterizes the spinal mobility of subjects with axial Spondyloarthritis (SpA) and Ankylosing Spondylitis (AS). It is a disease-specific measure consisting of 5 clinical measures to reflect subject axial status: cervical rotation; tragus to wall distance; lateral lumbar flexion; lumbar flexion (modified Schober test); intermalleolar distance. According to the linear definition of the BASMI a score of 0 to 10 is calculated for each item based on the measurement. The mean of the sum of the 5 scores provides the BASMI score. The higher the BASMI score the more severe the patient's limitation of movement due to their axial SpA. A negative value in BASMI change from Baseline indicates an improvement from Baseline. The higher the negative value the better the improvement.
  • 12. Change from Baseline in the Maastricht Ankylosing Spondylitis Enthesitis (MASES) Index in the subgroup of subjects with enthesitis at Baseline at Week 16 [ Time Frame: Baseline, Week 16 ]
    The Maastricht Ankylosing Spondylitis Enthesitis (MASES) is an index that measures the severity (ie, intensity and extent) of enthesitis through the assessment of 13 entheses (bilateral costochondral 1, costochondral 7, anterior superior iliac spine, posterior iliac spine, iliac crest and proximal insertion of the Achilles tendon sites, and the fifth lumbar vertebral body spinous process) each scored as 0 or 1 and then summed for a possible score of 0 to 13. A higher score indicates worsening.
  • 13. Enthesitis-free state based on the Maastricht Ankylosing Spondylitis Enthesitis Index (MASES) Index in the subgroup of subjects with enthesitis at Baseline at Week 16 [ Time Frame: Baseline, Week 16 ]
    The Maastricht Ankylosing Spondylitis Enthesitis (MASES) is an index that measures the severity (ie, intensity and extent) of enthesitis through the assessment of 13 entheses (bilateral costochondral 1, costochondral 7, anterior superior iliac spine, posterior iliac spine, iliac crest and proximal insertion of the Achilles tendon sites, and the fifth lumbar vertebral body spinous process) each scored as 0 or 1 and then summed for a possible score of 0 to 13. A higher score indicates worsening.
  • 14. Incidence of treatment-emergent adverse events (TEAEs) during the study [ Time Frame: From Baseline (Day 1) until Safety-Follow-Up (up to Week 72) ]
    An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
  • 15. Incidence of serious adverse events (SAEs) during the study [ Time Frame: From Baseline (Day 1) until Safety-Follow-Up (up to Week 72) ]
    A serious adverse event (SAE) is any untoward medical occurrence that at any dose: Results in death Is life-threatening Requires in patient hospitalisation or prolongation of existing hospitalisation Is a congenital anomaly or birth defect Is an infection that requires treatment with parenteral antibiotics Other important medical events which based on medical or scientific judgement may jeopardise the patients, or may require medical or surgical intervention to prevent any of the above
  • 16. Adverse events (AEs) leading to withdrawal from investigational medicinal product (IMP) during the study [ Time Frame: From Baseline (Day 1) until Safety-Follow-Up (up to Week 72) ]
    An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
