Study Endpoints

Primary Endpoints

Percentage of participants achieving ASAS40.
Baseline to week 16

ASAS40 response is defined at least a 40% improvement in at least three of the four main ASAS domains, with no worsening in the remaining domain: Patient Global Assessment of Disease Activity (Q3 of ASDAS-CRP), Pain Assessment (BASDAI Q2), physical function (Bath Ankylosing Spondylitis Functional Index \[BASFI\]), and Inflammation (represented by the mean of the two morning stiffness BASDAI questions Q5 and Q6).

Secondary Endpoints
