Background: Clinical research is needed to identify patients with axial spondyloarthritis (axSpA) who are more likely to be responsive to interleukin (IL)-17 inhibition. Objectives: To evaluate short-term efficacy of secukinumab in the management of axSpA. Method: Twenty-one patients (7 males, 14 females) with axSpA were consecutively treated with secukinumab. Laboratory and clinical assessments were based on erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Ankylosing Spondylitis Disease Activity Score (ASDAS)-CRP, and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Data were recorded at baseline and at a 3 month follow-up visit. Results: The study was comprised of 21 patients. Both BASDAI and ASDAS-CRP showed a statistically significant reduction between the baseline and the 3 month visit (P < 0.0001 and P = 0.0005, respectively). During the laboratory assessment, ESR showed a significant decrease (P = 0.008) while CRP improvement did not reach statistical significance (P = 0.213). No statistical significance was observed between patients treated with secukinumab 150 mg vs. 300 mg in BASDAI (P = 0.99), ASDAS-CRP (P = 0.69), ESR (P = 0.54), and CRP (P = 0.56). No significant differences emerged between the BASDAI (P = 0.15), ASDAS-CRP (P = 0.09), and CRP (P = 0.15) rates in biologic-naïve patients and those previously failing tumor necrosis factor-α inhibition. Conversely, ESR decrease was significantly higher in the biologic-naïve subgroup (P = 0.01). No adverse events were reported. Conclusions: Secukinumab has proven remarkable short-term effectiveness, regardless of the biologic treatment line. A dosage of 150 mg proved to be appropriate in the clinical and laboratory management of axSpA.
