Clinical Efficacy of Alternative TNF Inhibitor and Secukinumab Between Primary Non-responder and Secondary Non-responder of Prior TNF Inhibitor in Ankylosing Spondylitis

This study demonstrated comparable drug retention between AS patients treated with alternative TNFi and secukinumab after failing to respond to prior TNFi therapy. The objective of this study was to compare the drug retention times and clinical efficacy of alternative TNFi and secukinumab in primary and secondary
non-responders with AS.

This data will influence decision making in respect to changing biologics in patients who fail prior TNFi therapy. In particular, clinicians can base the decision on whether the AS patient is a primary or secondary non-responder.
