Abstract

Objective: To assess the efficacy and safety of secukinumab in patients with rheumatoid arthritis (RA) who failed to respond to tumour necrosis factor- α (TNF-α) inhibitors. Method: This phase III double-blind, double-dummy, placebo-controlled study (NCT01770379) randomized (1:1:1) patients to subcutaneous secukinumab 150 mg, secukinumab 75 mg, or placebo at baseline, weeks 1, 2, 3, and 4, and then every 4 weeks. American College of Rheumatology (ACR) 20 response at week 24 was the primary endpoint. Secondary outcomes included the 28-joint Disease Activity Score using C-reactive protein (DAS28-CRP), Health Assessment Questionnaire Disability Index (HAQ-DI), and ACR50 at week 24. Long-term treatment was planned for 5 years. Results: ACR20 response rates at week 24 for the secukinumab 150 mg and 75 mg groups were not statistically superior to placebo. None of the secondary endpoints was met for either secukinumab dose. Although not statistically significant, compared with placebo, numerically greater differences in least squares mean changes from baseline in HAQ-DI score and numerically higher ACR50 response rates were observed at week 24 in both secukinumab treatment groups. No new or unexpected adverse events were observed in this study compared with the large secukinumab safety database across psoriasis, psoriatic arthritis, ankylosing spondylitis, and other RA studies. Conclusions: Given that other second-line therapies have demonstrated efficacy in RA patients who failed to respond to TNF-α inhibitors, these findings may suggest that interleukin-17A inhibition with secukinumab does not provide additional benefit to these patients. This study further confirms the well-characterized safety profile of secukinumab.
