The role of secukinumab in the treatment of psoriatic arthritis and ankylosing spondylitis

Abstract

Psoriatic arthritis and ankylosing spondylitis are chronic inflammatory diseases that can cause significant disability. The commercialization of the first tumour necrosis factor (TNF) inhibitors led to a radical improvement of the quality of life of people affected by these conditions; however, response was not universal, highlighting the need for alternative therapeutic targets. Secukinumab is a monoclonal interleukin (IL)-17A inhibitor which has been proven efficacious for psoriatic arthritis and ankylosing spondylitis in recent clinical trials. Dactylitis, enthesitis, skin and nails are some of the domains in which the inhibition of IL-17 has shown significant improvements apart from the joints. Its safety profile and satisfactory medium- to long-term outcome data are some of the aspects suggesting its potential impact in treatment protocols in the short term.
