- Incidence of treatment-emergent adverse events (TEAEs) during the study [ Time Frame: From Entry Visit (Visit 1) until Last Visit (up to Week 208) ]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.
- Incidence of serious adverse event (SAE) during the study [ Time Frame: From Entry Visit (Visit 1) until Last Visit (up to Week 208) ]Once it is determined that a subject experienced an Adverse Event (AE), the seriousness of the AE must be determined. An SAE must meet 1 or more of the following criteria: death, life-threatening, significant or persistent disability/incapacity, congenital anomaly/birth defect, important medical event, initial inpatient hospitalization or prolongation of hospitalization.
- Subjects who withdrew due to an treatment-emergent adverse event (TEAE) during the study [ Time Frame: From Entry Visit (Visit 1) until Last Visit (up to Week 208) ]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.
- Subjects with Axial Spondyloarthritis International Society 40 % response criteria (ASAS40) at Week 48 calculated relative to Baseline of AS0008 [ Time Frame: Baseline of AS0008, Week 48 ]
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))
- Subjects with Axial Spondyloarthritis International Society 20 % response criteria (ASAS20) at Week 48 calculated relative to Baseline of AS0008 [ Time Frame: Baseline of AS0008, Week 48 ]
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 2 units 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))
- Change from Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) to Week 48 [ Time Frame: Baseline of AS0008, Week 48 ]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.
