Current Primary Outcome Measures (submitted: April 10, 2020)

Percentage of Participants in Part B Who Did Not Experienced a Flare [ Time Frame: From Week 48 to Week 96 ]

A participant was considered to have experienced a flare if the participant had an Ankylosing spondylitis disease activity score (ASDAS) greater or equal to (≥) 2.1 at 2 consecutive visits or an ASDAS greater than (>) 3.5 at any visit during Part B up until Week 96. A participant qualified for Part B only if he achieved sustained remission after 48 weeks of Open-Label certolizumab pegol (CZP) treatment. Sustained remission was achieved when a participant had an ASDAS less than (<) 1.3 at Week 32 or Week 36 (if ASDAS < 1.3 at Week 32, it must have been < 2.1 at Week 36; if ASDAS < 2.1 at Week 32, it must have been < 1.3 at Week 36) and an ASDAS < 1.3 at Week 48. Missing data were handled using non-response imputation (NRI) methods.

Original Primary Outcome Measures (submitted: July 20, 2015)

Percentage of subjects in Part B who do not experience a flare [ Time Frame: From Week 48 to Week 96 ]

A flare occurs when a subject has an Ankylosing spondylitis disease activity score (ASDAS) ≥ 2.1 at 2 consecutive visits or ASDAS > 3.5 at any visit during Part B. A subject qualifies for Part B only if in sustained remission after 48 weeks of open-label Certolizumab Pegol (CZP) treatment. Sustained remission is achieved when a subject has an ASDAS < 1.3 at Week 32 or Week 36 (if ASDAS < 1.3 at Week 32, it must be < 2.1 at Week 36 [or vice versa]) and at Week 48.

Disease activity was measured by categorical response variables:

  • ASDAS-Inactive Disease (ASDAS-ID): ASDAS < 1.3
  • ASDAS-Moderate Disease (ASDAS-MD): ASDAS ≥ 1.3, < 2.1
  • ASDAS-High Disease activity (ASDAS-HD): ASDAS ≥ 2.1, ≤ 3.5

• Time to Flare in Part B [ Time Frame: From Week 48 to Week 96 ]
  For those who met the criteria for flare (see primary efficacy variable), the time to flare was the length in days from randomization in Part B until the visit at which the criteria for flare were met. Participants who discontinued the study without meeting the criteria for flare were counted as experiencing a flare at the time of their last study visit. The time to flare was analyzed using Kaplan-Meier methods. If Kaplan-Meier Estimate was NA for all estimates then more than 75 % failed to meet the flare condition.

  Missing data were handled using non-response imputation (NRI) methods.
• Percentage of Participants With Axial SpondyloArthritis International Society 20 % Response Criteria (ASAS20) Response at Week 96 in Part B [ Time Frame: Week 96 ]
  The ASAS20 response was defined as an improvement 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 domains: Patient's Global Assessment of Disease Activity (PGADA), Pain assessment (total spinal pain NRS scores), Function (Bath Ankylosing Spondylitis Functional Index (BASFI)), Inflammation (mean of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) questions 5 and 6 concerning morning stiffness intensity and duration) and absence of deterioration in the potential remaining domain [deterioration was defined as a relative worsening of at least 20 % and an absolute worsening of at least 1 unit]. Missing data were handled using non-response imputation (NRI) methods.
• Percentage of Participants With Axial SpondyloArthritis International Society 40 % Response Criteria (ASAS40) Response at Week 96 in Part B [ Time Frame: Week 96 ]
  The ASAS40 response was defined as a relative improvement 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: Patient's Global Assessment of Disease Activity (PGADA), Pain assessment (total spinal pain NRS scores), Function (Bath Ankylosing Spondylitis Functional Index (BASFI)), Inflammation (mean of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) questions 5 and 6 concerning morning stiffness intensity and duration) and no worsening at all in the remaining domain.

• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.

• 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.
• Percentage of Participants With at Least One Adverse Event (AE) During Part B of the Study [ Time Frame: From Week 0 until the Safety Follow-up Visit (10 weeks after the last dose of study medication) ]
  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. For subjects with flare in Part B and do escape to CZP full-dose therapy, only TEAEs with an onset date prior to the start date of escape CZP full-dose therapy were included.
• Percentage of Participants With at Least One Adverse Event (AE) and Who Experienced a Flare During Part B of the Study [ Time Frame: From time of flare to Escape Week 12 ]
  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. For subjects with flare in Part B and do escape to CZP full-dose therapy, only TEAEs with an onset date after or on the start date of escape CZP full-dose therapy were included.

• Change from Baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 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 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.
