Results Overview

ASAS40 is defined as improvement from baseline of greater than or equal to (\>=) 40 % and absolute improvement from baseline of at least 2 units (range of 0 to 10) in at least 3 of the following 4 domains without any worsening in the remaining domain. 1. Patient Global: How active was your spondylitis on average during the last week? score ranges 0 (not active) to 10 (very active). 2. Spinal Pain: How much Pain of your spine due to Ankylosing spondylitis? score ranges 0 (no pain) to 10 (severe pain). 3. 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. 4. 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).

SECONDARY outcome

Timeframe: Baseline, Week 16

Population: All randomized participants who had baseline and post-baseline data for ASDAS.

ASDAS is a composite index to assess disease activity in AS. The parameters used for the ASDAS (with CRP as acute phase reactant) are 1. Total back pain 2. Patient global 3. Peripheral pain/swelling 4. Duration of morning stiffness and 5. 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 scores indicated higher disease activity. Least Square (LS) mean was determined by mixed-model repeated measures (MMRM) with treatment, baseline C-reactive protein (CRP) status, Tumor necrosis factor (TNF) inhibitors experience, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.

Population: All randomized participants who had baseline and post-baseline data for BASDAI.

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. LS mean was determined by MMRM with treatment, baseline CRP status, TNF inhibitors experience, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.

Population: All randomized participants who had baseline and post-baseline data for BASFI.

The BASFI is a participant-reported assessment that establishes a participant's functional baseline and subsequent response to treatment. The BASFI is composed with 10 questions to assess the disease severity, including the first 8 questions regarding to functional anatomy related activities and the remaining 2 questions related to daily activities of AS participants. Participants respond to each question using an NRS scale (range 0 to 10). The BASFI score is the average of the 10 responses and has a possible minimum value of 0 and a possible maximum value of 10, with a higher score indicating worse function. LS mean was determined by MMRM with treatment, baseline CRP status, TNF inhibitors experience, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.

Population: All randomized participants who had baseline and post-baseline data for SF-36 PCS score.

SF-36 consists of 36 questions measuring 8 health domains: physical functioning, bodily pain, role limitations due to physical problems, role limitations due to emotional problems, general health perceptions, mental health, social function, and vitality. The patient's responses are solicited using Likert scales that vary in length, with 3-6 response options per item. The SF-36 can be scored into the 8 health domains named above and two overall summary scores: physical component summary (PCS) and mental component summary (MCS) scores. The domain and summary scores range from 0 to 100; higher scores indicate better levels of function and/or better health. LS mean was determined by MMRM with factors for treatment, baseline CRP status, TNF inhibitors experience, baseline value, visit, baseline value-by-visit, and treatment-by-visit interaction as fixed factors.

ASAS-NSAID score is used to present the NSAID intake by considering the type of NSAID, the total dose and the number of days taking NSAID during a period of interest (PI). For the NSAID equivalence scoring system, "no NSAID intake" was set to a score value of 0, and the reference dose of NSAID (150 mg/day diclofenac) was set to a score value of 100. The Daily diclofenac-equivalent dose score was derived by converting each daily dose of NSAID to a percentage dose equivalent of 150 mg diclofenac. ASAS-NSAID score = (equivalent NSAID score) x (days of intake during PI) x (days per week)/(PI in days). The total score range is from 0 to 100, higher the score greater the NSAID intake and 0 represents no intake at all. A negative change from baseline indicates less NSAID consumption.
