Therapies in ankylosing spondylitis—from clinical trials to clinical practice

Until recently, the therapeutic options for patients suffering from active AS comprised NSAIDs and TNF inhibitor therapy. Although these are effective in a significant proportion of patients, not all patients respond and some are intolerant to these therapies. Therefore, there is a clear unmet treatment need in AS patients. This article reviews the evidence for targets currently being studied in AS. This includes the IL-12/23 inhibitor ustekinumab, the pan-Janus kinase inhibitor tofacitinib and the anti-IL-17A antibody secukinumab.
