About this trial

The goal of this clinical trial is to find out if the study drug will work as a new therapy for axSpA patients. This study is placebo-controlled, and evaluates if study drug can treat symptoms of axSpA, including global disease activity, pain, function and inflammation.

Trial outcomes

Primary outcomes

1

Percentage of participants achieving ASAS40.

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).

Time frame
Baseline to week 16

Secondary outcomes

1

Patient Global Assessment of Disease Activity (PGADA) using Q3 of ASDAS-CRP

Time frame
Baseline to week 16
2

Spinal pain [Numeric Rating Scale (NRS) using Question 2 of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)]

Time frame
Baseline to week 16
3

Physical function using Bath Ankylosing Spondylitis Functional Index (BASFI)

Time frame
Baseline to week 16
4

Inflammation, defined as the mean of Questions 5 and 6 of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)

Time frame
Baseline to week 16
