Abstract:
Anti-TNF agents have been used for the last two decades. However, targeting interleukin-17 (secukinumab (SEC)) is a relatively novel treatment option for spondyloarthritis (SpA). Therefore, SEC is frequently preferred after multi anti-TNF agents, in real life. Objectives: The objective of this study was to assess the retention rate and response of SEC in anti-TNF naïve and anti-TNF resistance patients in real life experience. Methods: HUR-BIO is a monocentric database of biologics including 2886 SpA patients, since 2005. SEC is approved at May 2018 in Turkey and 147 patients have used SEC by January 2020. Demographic and clinical data were obtained from HUR-BIO registry. SpA patients were classified as ankylosing spondylitis (AS) and non-radiographic SpA (nrAxSpA). Response and retention rate of SEC were determined regarding to anti-TNF naïve vs anti-TNF resistance patients. Kaplan-Meier analysis was used to estimate SEC retention rates. Results: In total, 147 axial SpA patients (96 (65.3%) AS and 51 (34.7%) nrAxSpA) were analyzed. Overall, 23/147 (15.7%) patients were anti-TNF naïve, 27 (18.4%) patients were 1 anti-TNF failure and 97 (65.9%) patients were ≥2 anti-TNF failure. Baseline characteristics of patients and the main causes of discontinuation of anti-TNF agents were shown in table. Median duration of SEC usage was 7.9 (min-max, 3.0-19.8) months in AS and 6.7 (min-max, 3.0-19.8) months in nrAxSpA group (p=0.365). SEC survival at 12 months was similar between AS and nrAxSpA patients (56% vs %52, p=0.315) (not shown).SEC survival was similar among anti-TNF naïve, one anti-TNF failure and ≥2 anti-TNF failure patients (Figure). BASDAI 50 response was reached in 61.5% of anti-TNF naïve, 42.1% of one anti-TNF failure and 43.2% of ≥2 anti-TNF failure patients at the last control (p=0.452). Patients who used ≤ 1 anti-TNF agent had a higher drug survival rate (%69 vs %46, p=0.027) at 1 year, in comparison with patients who used 〉 1 anti-TNF agents before SEC(not shown). Figure. Secukinumab survival in anti-TNF naïve, one anti-TNF failure and ≥2 anti-TNF failure patients Conclusion: For SpA, SEC is a relatively new player in biological era. When SEC launched for new treatment option, it is preferred mostly (almost 2/3) in multi anti-TNF resistance patients. Moreover, those difficult patients’ (usually female) treatment response and retention rate were not satisfactory than biological naïve patients. Table.
