[Current treatment for spondyloarthritis: focus on netakimab. A review]

Spondyloarthritis (SpA) is a group of rheumatic diseases that includes ankylosing spondylitis (AS), psoriatic arthritis (PsA) and a number of other diseases. SpA lead to a significant social problem, since it is a common pathology that debuts mainly at a young age, significantly impairing the ability to work and the ability to social contacts of the most active part of the population. For all the main types of chronic progressive SpA, biological agents (biologics) are of great importance in patients with persistent activity despite standard treatment, especially in the case of predominantly axial involvement, since in this case it is actually the only option for effective treatment, in addition to the constant use of non-steroidal anti-inflammatory drugs (NSAIDs). Over the past decade, interleukin-17A (IL-17A) inhibitors have taken the first place in therapy of SpA, because, according to modern ideas about pathogenesis, IL-17A may be a key target for therapeutic intervention in SpA. In terms of ensuring availability for Russian patients with SpA, it is of particular importance to the introduction of the original medication from the group of IL-17A inhibitors Netakimab (NTK). This review presents data from randomized clinical trials of NTK phases I, II and III in AS and PsA also post-registration observational studies of phase IV, including analysis of subpopulations of patients of special interest, in particular, patients with psoriatic spondylitis. NTK demonstrated high effectiveness in the treatment of SpA both in randomized clinical trials and in clinical practice. The drug is characterized by a rapid onset of clinical action and persistent maintenance of the achieved improvement, a complex effect on various manifestations of the disease, is able to have a structure-modifying effect and slow down the progression of both the erosive process and osteoproliferation. The safety profile of NTK is generally typical for the entire group of IL-17 inhibitors. The drug has low immunogenicity, which allows us to count on the possibility of many years of effective use. Resolutions of expert councils on the use of NTK in AS and PsA support the inclusion of this drug in clinical guidelines.
