Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants with Assessment in Ankylosing Spondylitis (ASAS) 20 response at Week 12.

    ASAS20 is defined as a \>= 20% improvement and an absolute improvement of \>= 1 units (on a scale of 0 to 10) from Baseline in at least 3 of the 4 domains (patient's global assessment, back pain, function and inflammation) with no deterioration in the remaining domain (where deterioration is defined as a worsening of \>= 20% and a net worsening of \>= 1 unit \[on a scale of 0 to 10\])

    Week 12

Secondary Outcomes (8)

  • Percentage of Participants with Assessment in Ankylosing Spondylitis (ASAS) 20 response at Week 24.

    Week 24

  • Percentage of Participants with Assessment in Ankylosing Spondylitis (ASAS) 40 response at Week 12 and Week 24.

    Week 12 and Week 24

  • Percentage of Participants with Assessment in Ankylosing Spondylitis (ASAS) 5/6 response at Week 12 and Week 24.

    Week 12 and Week 24

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

    Week 12 and Week 24

  • Change from baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) at Week 12 and Week 24.

    Week 12 and Week 24

  • +3 more secondary outcomes
