For more than 10 years, anti-TNF biologics were successfully employed to treat AS, with marked improvement of signs and symptoms in around 60% of the patients. Recent knowledge of the pathophysiology of spondyloarthritis has highlighted the emerging role of the IL-17/IL-23 axis. New therapies with selective biological drugs have emerged in the treatment of this pathology. In this review, we evaluated the effects of ixekizumab, a new anti–IL-17A, that was licensed both by EMA and FDA in August 2019 for the treatment of ankylosing spondylitis. The review highlights the efficacy and safety data of the 3 randomized controlled trials (COAST V-COAST W-COAST X) and those of the extension to 52 weeks of COAST V and COAST W.Keywords: ixekizumab, ankylosing spondylitis, randomized control trials
