Outcome Measures
Primary Outcomes (1)
Percentage of Participants Achieving an Assessment of Spondyloarthritis International Society 40 (ASAS40) Response
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).
