Overview
Secukinumab is a monoclonal antibody that inhibits interleukin 17A, which has been introduced into the treatment of axial spondyloarthritis (axSpA) after successful phase III clinical trials. The open-label extension of MEASURE studies 1, 2 and 3 demonstrated the long-term efficacy and safety of the drug.
The aim of the analysis is to evaluate the long-term effectiveness in real clinical practice in the Czech Republic.
Methods: A retrospective, open-label, cohort study of patients with axSpA treated with secukinumab in the national ATTRA registry was performed, in which patients with axSpA (radiographic and non-radiographic axSpA), who met the indication criteria of the Czech Society for Rheumatology for the biological treatment of spondyloarthritis, were monitored and treated. The following indicators were evaluated: survival on treatment, BASDAI, ASDAS, HAQ, and SF-36.
Results: A total of 243 patients with radiographic axSpA were included in the study. The drug survival of secukinumab was 70.8% after 12 months and 63.5% after 24 months of treatment. Clinically significant improvement in ASDAS (≥ 1.1) was achieved in 71.7% of patients. The HAQ score decreased from a mean of 1.3 ± 0.6 to 0.8 ± 0.6 during the first 2 years of treatment. Furthermore, all quality of life parameters evaluated by SF-36 were improved. The ability to work was another parameter evaluating the quality of life. During the 2-year treatment, 37.7% of patients with disabilities or incapacity for work regained their ability to work. On the contrary, 15.7% of working patients or job-seekers lost their ability to work. The safety of the treatment was good, and no new signs of toxicity appeared. In the non-radiographic axSpA group, only 29 patients with similar results have been monitored and treated to date.
Conclusion: Treatment survival, efficacy, and safety of secukinumab in real clinical practice are very good, and secukinumab represents a new therapeutic alternative for active axial SpA.
