Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Who do Not Experience a Flare (Combined Ixekizumab Treatment)
Time Frame: Week 64
|
A flare is defined as Ankylosing Spondylitis Disease Activity Score (ASDAS ≥2.1) at 2 consecutive visits, or ASDAS >3.5 at any visit during Period 2. ASDAS is a composite index to assess disease activity in AS. The parameters used for the ASDAS (with high sensitivity C-reactive protein (CRP) as acute phase reactant) are total back pain, patient global, peripheral pain/swelling, duration of morning stiffness and CRP in mg/L. The ASDAScrp is calculated with the following equation: 0.121×total back pain+0.110×patient global+0.073×peripheral pain/swelling+0.058×duration of morning stiffness+0.579×Ln(CRP+1). (CRP is in mg/liter, the range of other variables is from 0(normal) to 10(very severe); Ln represents the natural logarithm). Data from five variables combined to yield a score (0.6361 to no defined upper limit), where higher the score worse the disease activity. |

Week 64
|
Change From Baseline in Modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS)
Time Frame: Baseline, 2 Years
|
The mSASSS is a four-point scoring system for lateral radiographs of the lumbar and cervical spine and has been shown to reliably track disease progression over time, where: 0 = normal; 1 = sclerosis, squaring or erosion; 2 = syndesmophyte; 3 = bony bridge. By the scoring system of mSASSS of the spinal x-rays, a total of 24 sites were scored on the lateral cervical and lumbar spine: the anterior corners of the vertebrae from lower border of C2 to upper border T1 (inclusive), and from lower border of T12 to upper border of S1 (inclusive). Each corner was scored from 0 to 3, resulting in a range from 0 [no change] to 72 [progression]. |
Baseline, 2 Years
|
Percentage of Participants Achieving an Assessment of Spondyloarthritis International Society (ASAS)20 Response
Time Frame: Week 64
|
ASAS20 response is defined as a ≥20% improvement and an absolute improvement from baseline of ≥1 units (range 0 to 10) in ≥3 of 4 domains, and no worsening of ≥20% and ≥1 unit (range 0 to 10) in the remaining domain. The following ASAS domains are used: Patient Global: How active was your spondylitis on average during the last week? score ranges 0 (not active) to 10 (very active). Spinal Pain: How much Pain of your spine due to Ankylosing spondylitis? score ranges 0 (no pain) to 10 (severe pain). Bath Ankylosing Spondylitis Functional Index (BASFI): Participant asked to rate the difficulty associated with 10 individual basic functional activities. Participant response was captured using Numeric Rating Scale (NRS) (range 0 to 10) with a higher score indicating worse function. Inflammation based on mean of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Q5 & Q6 (mean of intensity & duration of stiffness): Score ranges from "0" (none) and "10" (very severe). |

Change From Baseline in the Individual Components of the ASAS Criteria
Time Frame: Baseline, Week 64
|
Patient Global: How active was your spondylitis on average during the last week? score ranges 0 (not active) to 10 (very active). Spinal Pain: How much Pain of your spine due to Ankylosing spondylitis? score ranges 0 (no pain) to 10 (severe pain). Bath Ankylosing Spondylitis Functional Index (BASFI): Participant asked to rate the difficulty associated with 10 individual basic functional activities. Participant response was captured using Numeric Rating Scale (NRS) (range 0 to 10) with a higher score indicating worse function. Inflammation based on Q5 & Q6 mean of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) (mean of intensity & duration of stiffness): Score ranges from "0" (none) and "10" (very severe). LS mean was determined by ANCOVA with treatment, geographic region, originating study, baseline value and Week 24 value as fixed factors. |
Baseline, Week 64
|
Percentage of Participants Achieving Bath Ankylosing Spondylitis Disease Activity Index 50 (BASDAI50) Response
Time Frame: Week 64
|
The BASDAI is a participant-reported assessment consisting of 6 questions that relate to 5 major symptoms relevant to radiographic axial spondyloarthritis (rad-axSpA): 1) Fatigue, 2) Spinal pain, 3) Peripheral arthritis, 4) Enthesitis, 5) Intensity, and 6) Duration of morning stiffness.
Participants need to score each item with a score from 0 to 10 (NRS).
Total score is obtained from the average of symptom scores ranging 0 (no problem) to 10 (worst problem), with a higher score indicating more severe AS symptom.
BASDAI50 represents an improvement of ≥50% of the BASDAI score from baseline.
|
Week 64
|
Change From Baseline in the Measure of High Sensitivity C-Reactive Protein (CRP)
Time Frame: Baseline, Week 64
|
High sensitivity CRP is the measure of acute phase reactant.
It was measured with a high sensitivity assay at the central laboratory to help assess the effect of ixekizumab on disease activity.
High sensitivity CRP is a sensitive laboratory assay for serum levels of C-Reactive Protein, which is a biomarker of inflammation.
LS mean was determined by ANCOVA with treatment, geographic region, originating study, baseline value and Week 24 value as fixed factors.
|
Baseline, Week 64
|
Change From Baseline in Bath Ankylosing Spondylitis Metrology Index (BASMI)
Time Frame: Baseline, Week 64
|
BASMI is a combined index comprising of the following 5 clinical measurements of spinal mobility in participants with radiographic axial spondyloarthritis (rad-axSpA).
The BASMI linear result is the average of the 5 assessments and ranges from 0 to 10. The higher the BASMI score the more severe the participant's limitation of movement due to their AS. LS mean was determined by ANCOVA with treatment, geographic region, originating study, baseline value and Week 24 value as fixed factors. |
Baseline, Week 64
|
Change From Baseline in Chest Expansion in Centimeters
Time Frame: Baseline, Week 64
|
Chest expansion is the difference, in centimeter (cm), between the circumference of the chest in maximal inspiration and maximal expiration.
While participants have their hands resting on or behind the head, the assessor will measure the chest encircled length by centimeter (cm) at the fourth intercostal level anteriorly.
Two tries were recorded.
The better measurement (larger difference) of 2 tries (in centimeters) was used for analyses.
LS mean was determined by ANCOVA with treatment, geographic region, originating study, baseline value and Week 24 value as fixed factors.
|
Baseline, Week 64
|
Change From Baseline in Occiput to Wall Distance
Time Frame: Baseline, Week 64
|
The participant is to make a maximum effort to touch the head against the wall when standing with heels and back against the wall (occiput).
Then the distance from occiput to wall is measured.
Two tries will be recorded.
The better (smaller) measurement of 2 tries (in centimeters) will be used for analyses.
LS mean was determined by ANCOVA with treatment, geographic region, originating study, baseline value and Week 24 value as fixed factors.
|

Change From Baseline in the European Quality of Life - 5 Dimensions 5 Level (EQ-5D-5L) UK Population-based Index Score
Time Frame: Baseline, Week 64
|
The European Quality of Life - 5 Dimensions 5 Level (EQ-5D-5L) is a standardized measure of health status used to provide a simple, generic measure of health for clinical and economic appraisal.
The EQ-5D-5L consists of 2 components: a descriptive system of the respondent's health and a rating of his/her current health state using a 0- to 100-mm visual analog scale (VAS).
The descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.
Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems.
LS mean was determined by ANCOVA with treatment, geographic region, originating study, baseline value and Week 24 value as fixed factors.

Change From Baseline in the Work Productivity Activity Impairment Spondyloarthritis (WPAI-SpA) Scores
Time Frame: Baseline, Week 64
|
The WPAI-SpA consists of 6 questions to determine employment status, hours missed from work because of SpA, hours missed from work for other reasons, hours actually worked, the degree to which SpA affected work productivity while at work, and the degree to which SpA affected activities outside of work.
The WPAI-SpA has been validated in the rad-axSpA participant population.
Four scores are derived: percentage of absenteeism, percentage of presenteeism (reduced productivity while at work), an overall work impairment score that combines absenteeism and presenteeism, and percentage of impairment in activities performed outside of work.
The computed percentage range for each sub-scale was from 0-100, with higher scores indicating greater impairment and less productivity.
LS mean was determined by ANCOVA with treatment, geographic region, originating study, baseline value and Week 24 value as fixed factors.
