Efficacy and safety of secukinumab in patients with giant cell arteritis: study protocol for a randomized, parallel group, double-blind, placebo-controlled phase II trial.

Background: One key pathological finding in giant cell arteritis (GCA) is the presence of interferon-gamma and interleukin (IL)-17 producing T helper (Th) 1 and Th17 cells in affected arteries. There is anecdotal evidence of successful induction and maintenance of remission with the monoclonal anti-IL-17A antibody secukinumab. Inhibition of IL-17A could therefore represent a potential new therapeutic option for the treatment of GCA.

Background: The prevalence of spondyloarthritis (SpA) in Germany is approximately 1-1.4% and includes predominantly axial SpA (axSpA) and predominantly peripheral SpA. Ankylosing spondylitis (AS) belongs to the group of axial SpA but also exhibits peripheral manifestations.
