Week 96
|
Change From Baseline in Ankylosing Spondylitis Disease Activity Score (ASDAS) at Week 96 in Part B
Time Frame: From Week 48 to Week 96
|
The ASDAS was calculated as the sum of the following components: 0.121 x Back pain (BASDAI Q2 result) 0.058 x Duration of morning stiffness (BASDAI Q6 result) 0.110 x PGADA (Patient's Global Assessment of Disease Activity) 0.073 x Peripheral pain/swelling (BASDAI Q3 result) 0.579 × (natural logarithm [ln] of the (CRP [mg/L] + 1)) Back pain, PGADA, duration of morning stiffness, peripheral pain/swelling and fatigue were all assessed on a numerical scale (0 to 10 units). There is a minimum score of 0.636 for the total ASDAS score, but no defined upper score. Based on the formula even in the situation that the CRP is normal, any value below 4 is recorded as "below the limit of quantification" (BLQ) and a value of BLQ/2=2 was prespecified. This assumption is triggering the lowest possible value of 0.636. The change from Part B Baseline is calculated, a negative value indicating improvement and a positive value worsening. |
From Week 48 to Week 96
|
Change From Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at Week 96 in Part B
Time Frame: From Week 48 to Week 96
|
The 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. The change from Part B Baseline is calculated, a negative value indicating improvement and a positive value worsening. |
From Week 48 to Week 96
|
Change From Baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) at Week 96 in Part B
Time Frame: From Week 48 to Week 96
|
The BASFI is a validated disease-specific instrument for assessing physical function. The BASFI comprises 10 items relating to the past week. The BASFI is the mean of the 10 scores such that the total score ranges from 0 (Easy) to 10 (Impossible), with lower scores indicating better physical function. The change from Part B Baseline is calculated, a negative value indicating improvement and a positive value worsening. |
From Week 48 to Week 96
|
Change From Baseline in Bath Ankylosing Spondylitis Metrology Index (BASMI) at Week 96 in Part B
Time Frame: From Week 48 to Week 96
|
The BASMI 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 was calculated for each item based on the measurement. The mean of the sum of the 5 scores provided the total BASMI score, ranging from 0 to 10. The higher the BASMI score the more severe the patient's limitation of movement due to their axial spondyloarthritis (axSpA). The change from Part B Baseline is calculated, a negative value indicating improvement and a positive value worsening. |
From Week 48 to Week 96
|
Percentage of Participants With Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 50 Response Criteria Response at Week 96 in Part B
Time Frame: Week 96
|
The BASDAI50 response was defined as an improvement of at least 50 % in the BASDAI score relative to Baseline. Missing data were handled using non-response imputation (NRI) methods. |
Week 96
|
Change From Baseline in Sacroiliac Spondyloarthritis Research Consortium of Canada (SPARCC) Score at Week 96 in Part B
Time Frame: From Week 48 to Week 96
|
The SPARCC scoring method for lesions found on the Magnetic Resonance Imaging (MRI) is based on an abnormal increased signal on the Short-Tau-Inversion Recovery (STIR) sequence, representing bone marrow edema. Total Sacroiliac (SI) joint SPARCC score can range from 0 to 72 with higher scores indicating higher joint inflammation. The change from Part B Baseline is calculated, a negative value indicating improvement and a positive value worsening. |
From Week 48 to Week 96
|
Change From Baseline in Spine Ankylosing Spondylitis Spine Magnetic Resonance Imaging Score for Disease Activity (ASspIMRI-a) in the Berlin Modification Score at Week 96 in Part B
Time Frame: From Week 48 to Week 96
|
The Berlin modification of the ASspiMRI-a is a scoring system with a concentration on Short-Tau-Inversion Recovery (STIR) sequences without other fat saturation techniques. It quantifies changes in 23 Vertebral Units (VU) of the spine. Active inflammation was scored by grading the degree of bone marrow edema from 0 to 3 in 1 dimension on 1 or more consecutive slices that represent the highest level of inflammation in a particular VU. The change from Part B Baseline is calculated, a negative value indicating improvement and a positive value worsening. |
From Week 48 to Week 96
|
Percentage of Participants in Ankylosing Spondylitis Disease Activity Score (ASDAS) Disease Activity Categories at Escape Week 12 for Participants Who Experienced a Flare in Part B
Time Frame: Escape Week 12

Change From Baseline in Ankylosing Spondylitis Disease Activity Score (ASDAS) at Escape Week 12 for Participants Who Experienced a Flare in Part B
Time Frame: From time of flare to Escape Week 12
|
The ASDAS was calculated as the sum of the following components: 0.121 x Back pain (BASDAI Q2 result) 0.058 x Duration of morning stiffness (BASDAI Q6 result) 0.110 x PGADA (Patient's Global Assessment of Disease Activity) 0.073 x Peripheral pain/swelling (BASDAI Q3 result) 0.579 × (natural logarithm [ln] of the (CRP [mg/L] + 1)) Back pain, PGADA, duration of morning stiffness, peripheral pain/swelling and fatigue were all assessed on a numerical scale (0 to 10 units). There is a minimum score of 0.636 for the total ASDAS score, but no defined upper score. Based on the formula even in the situation that the CRP is normal, any value below 4 is recorded as "below the limit of quantification" (BLQ) and a value of BLQ/2=2 was prespecified. This assumption is triggering the lowest possible value of 0.636. The change from Part B Baseline is calculated, a negative value indicating improvement and a positive value worsening. |

Change From Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at Escape Week 12 for Participants Who Experienced a Flare in Part B
Time Frame: From time of flare to Escape Week 12
|
The 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. The change from flare Baseline is calculated, a negative value indicating improvement and a positive value worsening. |

Change From Baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) at Escape Week 12 for Participants Who Experienced a Flare in Part B
Time Frame: From time of flare to Escape Week 12
|
The BASFI is a validated disease-specific instrument for assessing physical function. The BASFI comprises 10 items relating to the past week. The BASFI is the mean of the 10 scores such that the total score ranges from 0 (Easy) to 10 (Impossible), with lower scores indicating better physical function. The change from flare Baseline is calculated, a negative value indicating improvement and a positive value worsening. |

Change From Baseline in Bath Ankylosing Spondylitis Metrology Index (BASMI) at Escape Week 12 for Participants Who Experienced a Flare in Part B
Time Frame: From time of flare to Escape Week 12
|
The BASMI 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 was calculated for each item based on the measurement. The mean of the sum of the 5 scores provided the total BASMI score, ranging from 0 to 10. The higher the BASMI score the more severe the patient's limitation of movement due to their axial spondyloarthritis (axSpA). The change from flare Baseline is calculated, a negative value indicating improvement and a positive value worsening. |

Change From Baseline in Sacroiliac Spondyloarthritis Research Consortium of Canada (SPARCC) Score at Escape Week 12 for Participants Who Experienced a Flare in Part B
Time Frame: From time of flare to Escape Week 12
|
The SPARCC scoring method for lesions found on the Magnetic Resonance Imaging (MRI) is based on an abnormal increased signal on the Short-Tau-Inversion Recovery (STIR) sequence, representing bone marrow edema. Total Sacroiliac (SI) joint SPARCC score can range from 0 to 72 with higher scores indicating higher joint inflammation. The change from flare Baseline is calculated, a negative value indicating improvement and a positive value worsening. |

Change From Baseline in Spine Ankylosing Spondylitis Spine Magnetic Resonance Imaging Score for Activity (ASspIMRI-a) in the Berlin Modification Score at Escape Week 12 for Participants Who Experienced a Flare in Part B
Time Frame: From time of flare to Escape Week 12
|
The Berlin modification of the ASspiMRI-a is a scoring system with a concentration on Short-Tau-Inversion Recovery (STIR) sequences without other fat saturation techniques. It quantifies changes in 23 Vertebral Units (VU) of the spine. Active inflammation was scored by grading the degree of bone marrow edema from 0 to 3 in 1 dimension on 1 or more consecutive slices that represent the highest level of inflammation in a particular VU. The change from flare Baseline is calculated, a negative value indicating improvement and a positive value worsening. |

Certolizumab Pegol (CZP) Plasma Concentration During the Study
Time Frame: From Week 0 until the Safety Follow-up Visit (10 weeks after the last dose of study medication)
|
CZP plasma concentration was measured in micrograms per milliliter (μg/mL). Blood sample measurements that were deemed to be below the level of quantification, were set to half the lower level of quantification (LLOQ) for analysis purposes. Summary statistics were only displayed if at least two-thirds of the values were above the LLOQ and if n was greater or equal to (>=) 4. The primary purpose of the study was to evaluate treatment options for axSpA patients after being in sustained remission. Hence, one of the objectives was to evaluate the PK of these patients. The CZP plasma concentration of the patients that did not reach sustained remission were therefore not analysed, and the Pharmacokinetic Set A as described in the protocol was removed from the SAP. |

Percentage of Participants With Positive Anti-certolizumab Pegol-antibody Levels in Plasma During the Study
Time Frame: From Week 0 until the Safety Follow-up Visit (10 weeks after the last dose of study medication)
|
Treatment emergent ADAb status positive was defined as either baseline ADAb negative subjects having at least one ADAb confirmed positive sample post baseline or baseline ADAb positive subjects with at least one post baseline sample with >= minimum significant ratio (MSR) increase from baseline on CZP treatment. Once determined positive, the highest titer during Part A and Part B (including Escape and Safety Follow up) was used to categorize the subject. The primary purpose of the study was to evaluate treatment options for axSpA patients after being in sustained remission. Hence, one of the objectives was to evaluate the immunogenicity of these patients. The ADAb titer of the patients that did not reach sustained remission were therefore not analysed, and the Pharmacokinetic Set A as described in the protocol was removed from the SAP. |

Percentage of Participants With at Least One Adverse Event (AE) During Part A of the Study
Time Frame: From Screening Period (Week -5 to Week -1) until Week 48
|
An AE was any untoward medical occurrence in a patient or clinical investigation study participant administered a pharmaceutical product that did not necessarily have a causal relationship with this treatment.
An AE could therefore have been any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
