Anti-IL-17 monoclonal antibodies for the treatment of ankylosing spondylitis

INTRODUCTION: Ankylosing spondylitis is the prototype of spondyloarthritis, a chronic inflammatory disease involving mainly the axial skeleton. The treatment strategy was, until now, restricted to NSAIDs and anti-TNF agents. Targeting Interleukin 17 is an emerging option with a currently available biologic agent, secukinumab. AREAS COVERED: This paper reviews the available data published on secukinumab (and other anti-IL-17 agents) in ankylosing spondylitis, evaluating the effect on clinical outcomes as well as radiological progression and extra articular manifestations and safety. EXPERT OPINION: Secukinumab represents the first anti-IL-17A agent available for the treatment of ankylosing spondylitis, with evidence of efficacy upon signs and symptoms of the disease, even after anti-TNF failure, and acceptable safety profile.
