AUTHOR=Cheung Peter P. TITLE=Anti-IL17A in Axial Spondyloarthritis—Where Are We At? JOURNAL=Frontiers in Medicine VOLUME=Volume 4 - 2017 YEAR=2017 URL=https://www.frontiersin.org/journals/medicine/articles/10.3389/fmed.2017.00001 DOI=10.3389/fmed.2017.00001 ISSN=2296-858X ABSTRACT=Knowledge regarding the mechanisms of the IL17-IL23 pathway and its role in spondyloarthritis has been pivotal to the development of IL-17 blockade in patients with axial spondyloarthritis. Previously, only anti-TNF has proven to be clinically efficacious in patients with active disease despite non-steroidal anti-inflammatory drugs and physiotherapy. However, up to 50% fail to achieve a clinically significant response. Secukinumab, a fully humanised monoclonal antibody targeting IL-17a has recently been approved for use in patients with active ankylosing spondylitis. Clinical studies and current issues surrounding the use of secukinumab will be discussed.
