Design outcomes

Primary

MeasureTime frame
Main Objective: Efficacy of ixekizumab (LY2439821) compared to placebo in participants with active ankylosing spondylitis based on ASAS20 at 16 Weeks; Secondary Objective: Efficacy of either ixekizumab compared to placebo in patients with active AS based on the following measures at Week 16: -Proportion of biologic naïve patients who achieve an ASAS40 response. -peripheral tender or swollen joint counts -Change from baseline in patient-reported quality of life and other outcomes assessments -Change from baseline in non-arthritic aisease assessments -spinal mobility Efficacy of either ixekizumab compared to placebo in patients with active AS based on the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) change from baseline at Week 108. ; Primary end point(s): Efficacy of ixekizumab in participants with Ankylosing Spondylitis (AS). Measure: Assessment of Spondyloarthritis International Society (ASAS) 20 Response ;Timepoint(s) of evaluation of this end point: At 16 Weeks
