Treatment of psoriatic arthritis with secukinumab: a case series

Psoriatic arthritis (PsA) is a chronic inflammatory disorder affecting up to 30% of psoriatic patients, worsening patients' quality of life. Secukinumab, a fully humanized monoclonal antibody that selectively inhibits interleukin (IL) 17 A, has been recently approved for the treatment of PsA in adults, alone or in association with methotrexate (MTX). In the secukinumab registration studies, the primary endpoint was evaluated at 24 weeks; whether there is an early response in patients with psoriatic arthritis is not well characterized. Furthermore, the registration studies included a hierarchical analysis of end-points that led to a missing evaluation of many secondary endpoints.
